This document summarizes research on the effects of Chinese herbal medicine on tumor-related T cells. It begins by providing background on traditional Chinese medicine and its use alongside Western medicine to treat cancer in China. It then describes different types of T cells (e.g. cytotoxic T cells, helper T cells) and their roles in tumor progression and inhibition. The document reviews studies showing that Chinese herbal medicines can increase T cell production, enhance T cell regulation and ratios, and promote normal T cell function to reduce cancer therapy side effects. It concludes that while promising herbal agents have been identified, most Chinese herbal mechanisms remain undiscovered, representing a rich area for further research.
Case reports and studies may be defined as the non-experimental description of an individual or a few of cases in terms of new or unusual presentation of the diseases, an unexpected disease course or pathophysiology, and new effects (either beneficial or detrimental) of existing medications or procedures. Although they suffer from the non-experimental nature and other potential bias and errors, case reports and studies have played and will continue to play an important part in the advancement of medicine. They often serve as "primers" leading to discoveries of new diseases/disease pathophysiology as well as development of new preventive and therapeutic measures. Case reports and case studies are also employed as a platform for the training of medical students and/or resident doctors in scientific writing and critical thinking. Although the significance of case reports and studies in medicine has being recognized since the early stage of development of clinical medicine, their value needs to be appreciated in the context of modern clinical research design and the hierarchy of strength of evidence for guiding patient care. This paper discusses case reports and studies within the big picture of clinical research, research design, and evidence-based practice.

Annual advances of Chinese minority traditional medicine in 2019LucyPi1
Abstract Traditional medicine systems practiced by various ethnic minorities represent an important part of traditional Chinese medicine. The past 12 months have witnessed extensive research pertaining to different Chinese minority traditional medicine (CMTM). The annual CMTM review evaluates research published during 2019 in different CMTM including Tibetan medicine, Uyghur medicine, Mongolian medicine, Korean medicine and Zhuang medicine. Research in the field of Tibetan medicine focused on pharmacology, pharmacy, plant sciences, medicinal chemistry and integrated complementary medicine and the top three countries were China, USA and India. Research in Uyghur medicine mainly pertained to chemistry, pharmacology, pharmacy, and food science technology and the publications were mainly from China. Research in Mongolian medicine mainly pertained to pharmacology, pharmacy, analytical chemistry, biochemistry, molecular biology and experimental research; the publications were mainly from China and Mongolia. In short, research related to traditional medicine of various ethnic minorities was mainly conducted in China and the neighboring countries. The research focus for each minority medicine is essentially on the effects and mechanisms of action of the active ingredients of the ethnodrugs and the special prescriptions or therapies. The generated evidence will facilitate further developments in this field.
The Evolution of Future Medicine - WE Medicine - To Meet Unmet Medical Needs_...CrimsonpublishersCancer
The medicines needed today are not just for the treatment of disease, but for the treatment of the whole person across his or her lifetime - from disease prevention to disease progression, modulating the efficacy and safety of other medicines, and improving quality of life.
Currently many pharmaceutical and biotech companies are focusing primarily on the treatment versus the prevention of disease, with the exception of developing vaccines against infectious agents as preventative measurement. Developing small molecule medicines still largely applies a reductionist approach focused on a particular target and developing selective and potent chemicals aimed at it. The advancement of knowledge and modern technologies has facilitated the reductionist approach and led to the discovery of a few interesting target- oriented drugs with varying degrees of success, however this approach has not been satisfactory for the treatment of more complex, heterogeneous diseases which are often associated with the aging process [1]. It is recognized that the selected target in most cases is not only important for the pathogenesis of disease, but also plays an important role in the normal functions of the body. With highly potent chemicals used on long term basis, toxicity in normal tissues will often evolve.
Personalized Therapies for OA: Can Biomarkers Get Us There?OARSI
This document discusses the potential for using biomarkers to enable personalized therapies for osteoarthritis (OA). It defines key terms like personalized therapies, biomarkers, phenotypes, and endotypes. The presenter argues that biomarkers could help identify the right treatment for individual OA patients by enabling prognostic and predictive enrichment in clinical trials. However, moving biomarkers from discovery to clinical validation and use involves a long process including assay development, testing biological links and hypotheses, and conducting randomized controlled trials. Several studies are highlighted that have discovered potential new biomarkers and are beginning to test biological links and hypotheses regarding how biomarkers may reflect disease processes and response to treatments.
This document discusses the need for ethically responsible choice architecture in prostate cancer treatment decision making. It notes that while patients are assumed to make autonomous decisions, evidence shows that for prostate cancer many men may not be properly informed of their options, especially active surveillance. Decision making can be influenced by biases and heuristics that favor immediate intervention over active surveillance. The document advocates for clinicians to engage in choice architecture that encourages men to seriously consider the harms of immediate intervention and benefits of active surveillance when deciding on treatment. This could be done through framing options, appealing to social norms, and using patient narratives. The goal is to raise awareness of active surveillance as an appropriate option for eligible men.

Abstract Objective: Traditional Chinese medicine (TCM) has been extensively used as one of popular alternative therapies for several cancers. However, it remains unclear whether TCM treatment is associated with longer survival in lung cancer patients. In this study, we explored the effect of long-term TCM treatment on patients with different stages of lung cancer. Methods: All information of lung cancer patients with stage I-III disease from January 2007 to September 2015 was collected for this retrospective cohort study. Those who were treated with TCM after surgery were divided into TCM group and the others were into the non-TCM group (control group). All patients were regularly followed up by clinic appointment or phone, and all survival data were collected from databases after the last follow-up in October 2017. Results: A total of 575 patients were included in this study, with 299 patients in the TCM group and 276 in the control group. For all patients, 5-year disease-free survival (DFS) was 62.2% in TCM group and 42.1% in the control group, and 6-year DFSs were 51.8% and 35.4%, respectively (HR = 0.51, 95% CI: 0.40 to 0.66, log-rank P ≤ 0.001). For patients with stage I, 5-year DFSs were 83.7% (TCM group) and 57.5% (control group) and 6-year DFSs were 73.7% and 51.9%, respectively (HR = 0.30, 95% CI: 0.18 to 0.50, log-rank P ≤ 0.001). For patients with stage II in the TCM group and the control group, 5-year DFSs were 59.4% and 17.6% and 6-year DFSs were 44.7% and 17.6%, respectively (HR = 0.31, 95% CI: 0.19 to 0.52, log-rank P ≤ 0.001), and for patients with stage III, 5-year and 6-year DFSs in the TCM group were 18.7% and 12.5% compared with 28.4% and 20.3% in the control group (HR = 1.06, 95% CI: 0.72 to 1.56, log-rank P = 0.76). Conclusions: This study demonstrated that long-term TCM treatment as an adjuvant therapy is able to improve the DFS of postoperative stage I-III lung cancer patients, especially in patients with stage I and II disease. However, these observational findings need being validated by large sample randomized controlled trials.

This study examined how intensivists make decisions about withholding or withdrawing life-sustaining treatment for critically ill patients at the end of life. In-depth interviews were conducted with 12 intensivists from two hospitals in the UK. The analysis identified three main themes that influenced intensivists' decision-making: their role and responsibilities, considerations of treatment effectiveness, and the patient's best interests. Two overarching tensions also emerged: balancing prolonging life versus quality of life, and balancing their sense of responsibility with the burden of end-of-life decisions. The results provide insight into how intensivists make sense of death and the role that their own beliefs play in complex end-of-life decision-making

The document summarizes a qualitative study that explored how a colorectal cancer diagnosis and treatment impacted patients' quality of life in Jordan. Ten Jordanian patients diagnosed with colorectal cancer participated in semi-structured interviews. Analysis of the interviews identified four main categories reflecting changes in patients' quality of life: 1) perceptions of quality of life such as diminished physical fitness and treatment side effects, 2) cancer as a source of distress through emotions, outlook on the future, and lost confidence, 3) changing roles like dependencies and altered responsibilities, and 4) changes in social life including isolation and disrupted family life. The study provides insight into how colorectal cancer affected patients' lives physically, psychologically, and socially.
The importance of sex and gender in medical researchCoda Change
The importance of sex and gender in medical research.
For many years it was widely assumed that the occurrence and outcome of disease was the same for women and men.
Our understanding was that studies involving only men would be equally relevant for women. In the last two decades however, it has been shown that this assumption is highly prejudice and can have a detrimental impact on the health of women.
It is, therefore, really important to incorporate a sex and gender research lens in to medical research.
First, Kelly makes the important distinction between sex and gender and how this can impact medical diagnosis, treatment and outcomes.
Then, she identifies how the incorporation of sex and gender into research has allowed for advancements across healthcare. Improved accuracy, avoiding misinterpretation, reduced unintentional bias and greater social equity to name a few.
In this presentation, Kelly Thompson refers to case studies to examine the differences in the interpretation of health data when examining through a sex and gender research lens.
The severity of disease, risk factors and treatment effectiveness are just a few of the reasons why this is so important.
Kelly encourages researchers to ensure gender diversity in the research team and to explain how sex and gender are accounted for in research applications moving forward.
From CodaZero Live, tune into this fascinating discussion on the importance of sex and gender in medical research by Kelly Thompson.
This document summarizes a systematic review that aimed to identify studies measuring health-related quality of life (HRQL) in tuberculosis (TB) patients using standardized instruments. The review identified 12 original studies meeting the criteria. A variety of generic and disease-specific HRQL instruments were used, with the Short Form-36 being most common. The studies found that TB significantly impacts patients' physical, psychological, and social well-being. Treatment improves HRQL but patients' quality of life remains worse than the general population even after being microbiologically cured. There is a need for a validated TB-specific HRQL instrument.
This document summarizes a systematic review of randomized controlled trials evaluating natural products for the treatment of chronic plaque psoriasis. Three studies with a total of 127 participants were included that evaluated Mahonia aquifolium, topical Aloe vera, and Chinese herbal medicines. Results were mixed, with one study finding improvement in psoriasis severity with Aloe vera compared to conventional treatment at 2 months, but another found Chinese herbal medicines were less effective than conventional treatment at 6 months. Adverse events were similar between natural products and conventional treatments in one study. Quality of life measures did not differ. Due to variability in natural products studied and limited evidence, applicability and safety of natural products for psor

Adverse Events among HIV/MDR-TB Co-Infected Patients Receiving Antiretroviral...Dr.Samsuddin Khan
Abstract
Background
Significant adverse events (AE) have been reported in patients receiving medications for multidrug- and extensively-drug-resistant tuberculosis (MDR-TB & XDR-TB). However, there is little prospective data on AE in MDR- or XDR-TB/HIV co-infected patients on antituberculosis and antiretroviral therapy (ART) in programmatic settings.
Methods
Médecins Sans Frontières (MSF) is supporting a community-based treatment program for drug-resistant tuberculosis in HIV-infected patients in a slum setting in Mumbai, India since 2007. Patients are being treated for both diseases and the management of AE is done on an outpatient basis whenever possible. Prospective data were analysed to determine the occurrence and nature of AE.
Results
Between May 2007 and September 2011, 67 HIV/MDR-TB co-infected patients were being treated with anti-TB treatment and ART; 43.3% were female, median age was 35.5 years (Interquartile Range: 30.5–42) and the median duration of anti-TB treatment was 10 months (range 0.5–30). Overall, AE were common in this cohort: 71%, 63% and 40% of patients experienced one or more mild, moderate or severe AE, respectively. However, they were rarely life-threatening or debilitating. AE occurring most frequently included gastrointestinal symptoms (45% of patients), peripheral neuropathy (38%), hypothyroidism (32%), psychiatric symptoms (29%) and hypokalaemia (23%). Eleven patients were hospitalized for AE and one or more suspect drugs had to be permanently discontinued in 27 (40%). No AE led to indefinite suspension of an entire MDR-TB or ART regimen.
Conclusions
AE occurred frequently in this Mumbai HIV/MDR-TB cohort but not more frequently than in non-HIV patients on similar anti-TB treatment. Most AE can be successfully managed on an outpatient basis through a community-based treatment program, even in a resource-limited setting. Concerns about severe AE in the management of co-infected patients are justified, however, they should not cause delays in the urgently needed rapid scale-up of antiretroviral therapy and second-line anti-TB treatment

This document discusses the need for geriatric assessments (GAs) in older cancer patients undergoing treatment. GAs evaluate patients' functional status, medical conditions, cognition, nutrition, social support and medications. The document aims to analyze evidence on how GAs impact treatment decisions and patient outcomes. It describes how GAs may alter treatments in up to 49% of patients by identifying age-related vulnerabilities. Studies show GAs correlate with survival rates, quality of life and toxicity risks. While GAs provide useful information, more research is still needed on their optimal use in oncology.
This document summarizes a study on risk factors, health problems, reasons for admission, and knowledge of diabetes patients admitted to a hospital in Nepal. The study found that over half of patients were aged 40-60 years old, Hindu, and non-vegetarian. Many had complications like hypertension, eye and kidney problems. Patients had some knowledge of their disease but lacked understanding of causes, treatments, diet etc. There is a need for better health education programs to improve patient knowledge and care of diabetes in Nepal.

Abstract Background: Postoperative nausea and vomiting (PONV) refers to a problem commonly occurring after surgery. Acupuncture is considered a critical complementary alternative therapy for PONV. The acupoints selection critically determines the efficacy of acupuncture, whereas the selection rules remain unclear. The objective of the present study was to delve into the principles of acupoints selection for PONV using data mining technology. Methods: The clinical trials assessing the acupuncture effect for PONV were searched with the use of computer in PubMed, China National Knowledge Infrastructure, and Chinese Biomedical Database; the time span was confined as 2009–2019. The database of acupuncture prescriptions for PONV was built using Excel 2016; the description and association were analyzed by IBM SPSS modeler 18. Result: Eighty-three relevant literatures were screened out. The number of specific acupoints took up 72.5% of all acupoints; specific acupoints exhibited the frequency taking up 91.30% of the total frequency. As revealed from the result, Neiguan (PC 6), Zusanli (ST 36), Hegu (LI 4), and Zhongwan (CV 12) were most frequently applied, suggesting the tightest associations. Most acupoints were taken from the stomach meridian and pericardium meridian. The common acupoints were concentrated in the lower limbs, chest, as well as abdomen. Conclusion: Data mining acts as a feasible method to identify acupoints selection and compatibility characteristics. As suggested from our study, the acupoints selection for PONV prioritizes specific acupoints and related meridians. The selection and combination of acupoints comply with the theory of traditional Chinese medicine.
East to west: research progress in traditional Chinese medicine for antiaging...LucyPi1
Abstract Delaying the onset of aging is considered an important tool for dealing with the global crisis of the aging population. Accordingly, several antiaging studies have been conducted using strategies of modern medicine and traditional Chinese medicine (TCM). In this review, we summarize the current state of antiaging research related to both modern medicine and TCM and provide suggestions for further research. Various theories related to the aging process have been proposed, including the free radical theory, mitochondrial DNA damage theory, telomere theory, cross-linking theory, and intestinal flora theory, and a number of antiaging chemical treatments have been developed using modern medicine. These theories and achievements have resulted in major advancements in antiaging research. TCM is based on practical experience and has a long history with unique advantages in antiaging research. Some antiaging practices such as moderate diet consumption, acupuncture, Tai Chi (a traditional Chinese martial art that can relax the nerves to slow down the aging process), and Wuqin Xi (a traditional Chinese exercise to strengthen the body) have been adopted to maintain health. Several TCMs and prescriptions, particularly those related to medicine food homology, have been used in antiaging treatment, and their antiaging properties have been demonstrated to be effective based on pharmacological experiments and clinical applications.
The document discusses enhancing quality of life as an important goal for cancer treatment. It notes that while treatments have increased survival rates, they can also cause chronic health issues for survivors that reduce quality of life. More research is needed to better understand and prevent these toxic side effects, through identifying biomarkers and mitigation strategies. The authors call for increased priority and resources for quality of life research to both improve existing treatments and enable more patients to benefit from new therapies.
Herbal Medicine for Cancer Treatment: Main Force or Supplement_Crimson Publis...CrimsonpublishersCancer
The Estimated numbers of new cancer cases and deaths in 2020 will be an estimated. 1.8 million new cancer cases diagnosed and 606,520 cancer deaths in the United States and there were 17 million new cases of cancer worldwide in 2018 [1]. The four most common cancers occurring worldwide are lung, female breast, bowel and prostate. A person’s risk of developing cancer depends on different factors, including age, genetics, and exposure to some potentially known carcinogens and those which are believed to be carcinogenic. Some avoidable lifestyle factors including smoking can increase cancer risk. However, cancer risk factors are similar worldwide. Insufficient exercise, alcohol, imbalanced diet, and obesity, and various infections account for a considerable proportion of cancers worldwide. Prevalence of any one of the risk factors varies in different ethnic groups and can vary by region and country, which contributes to variation of cancer incidence rates of the common types of cancer worldwide.
Annual advances in traditional medicine for tumor therapy in 2019LucyPi1
Abstract Today, the treatment of tumors remains a difficult problem. Traditional medicine has been used to treat cancer in different countries worldwide. However, while traditional medicine is popular globally, it is not yet accepted by Western medicine as some of the ingredients and the mechanism of action for the therapeutic effect have not been fully elucidated. Thus, scholars studying traditional medicine in the treatment of cancer have strived to solve this problem. In this review, we summarized the research progress of several traditional medicines used as tumor therapies in 2019 from the PubMed database. Studies of tumors treated with traditional Chinese medicine (TCM) are popular worldwide and obtain the most attention, which attracts more researchers to this field. The anti-tumor effects of Chinese herbal medicine-derived phytochemicals, such as polyphenols, polysaccharides, saponins, and alkaloids were the new research targets for 2019. The anti-tumor effects of TCM formula such as Sijunzi decoction, and Xiaopi formula have attracted the most attention in the past year. In addition to TCM, we also focused on the anti-tumor studies of other traditional medicines, including Thai traditional medicine, traditional medicine in Sri Lanka, traditional African medicine, traditional Korean medicine, and traditional Japanese medicine.

It also discusses concepts like informed consent, surrogate decision making, conscientious objection, and the ethical treatment of children and animals in medical research.
This study examined how intensivists make decisions about withholding or withdrawing life-sustaining treatment for critically ill patients at the end of life. In-depth interviews were conducted with 12 intensivists from two hospitals in the UK. The analysis identified three main themes that influenced intensivists' decision-making: their role and responsibilities, considerations of treatment effectiveness, and the patient's best interests. Two overarching tensions also emerged: balancing prolonging life versus quality of life, and balancing their sense of responsibility with the burden of end-of-life decisions. The results provide insight into how intensivists make sense of death and the role that their own beliefs play in complex end-of-life decision-making

The document summarizes a qualitative study that explored how a colorectal cancer diagnosis and treatment impacted patients' quality of life in Jordan. Ten Jordanian patients diagnosed with colorectal cancer participated in semi-structured interviews. Analysis of the interviews identified four main categories reflecting changes in patients' quality of life: 1) perceptions of quality of life such as diminished physical fitness and treatment side effects, 2) cancer as a source of distress through emotions, outlook on the future, and lost confidence, 3) changing roles like dependencies and altered responsibilities, and 4) changes in social life including isolation and disrupted family life. The study provides insight into how colorectal cancer affected patients' lives physically, psychologically, and socially.
The importance of sex and gender in medical researchCoda Change
The importance of sex and gender in medical research.
For many years it was widely assumed that the occurrence and outcome of disease was the same for women and men.
Our understanding was that studies involving only men would be equally relevant for women. In the last two decades however, it has been shown that this assumption is highly prejudice and can have a detrimental impact on the health of women.
It is, therefore, really important to incorporate a sex and gender research lens in to medical research.
First, Kelly makes the important distinction between sex and gender and how this can impact medical diagnosis, treatment and outcomes.
Then, she identifies how the incorporation of sex and gender into research has allowed for advancements across healthcare. Improved accuracy, avoiding misinterpretation, reduced unintentional bias and greater social equity to name a few.
In this presentation, Kelly Thompson refers to case studies to examine the differences in the interpretation of health data when examining through a sex and gender research lens.
The severity of disease, risk factors and treatment effectiveness are just a few of the reasons why this is so important.
Kelly encourages researchers to ensure gender diversity in the research team and to explain how sex and gender are accounted for in research applications moving forward.
From CodaZero Live, tune into this fascinating discussion on the importance of sex and gender in medical research by Kelly Thompson.
This document summarizes a systematic review that aimed to identify studies measuring health-related quality of life (HRQL) in tuberculosis (TB) patients using standardized instruments. The review identified 12 original studies meeting the criteria. A variety of generic and disease-specific HRQL instruments were used, with the Short Form-36 being most common. The studies found that TB significantly impacts patients' physical, psychological, and social well-being. Treatment improves HRQL but patients' quality of life remains worse than the general population even after being microbiologically cured. There is a need for a validated TB-specific HRQL instrument.

Three studies with a total of 127 participants were included that evaluated Mahonia aquifolium, topical Aloe vera, and Chinese herbal medicines. Results were mixed, with one study finding improvement in psoriasis severity with Aloe vera compared to conventional treatment at 2 months, but another found Chinese herbal medicines were less effective than conventional treatment at 6 months. Adverse events were similar between natural products and conventional treatments in one study. Quality of life measures did not differ. Due to variability in natural products studied and limited evidence, applicability and safety of natural products for psor

Adverse Events among HIV/MDR-TB Co-Infected Patients Receiving Antiretroviral...Dr.Samsuddin Khan
Abstract
Background
Significant adverse events (AE) have been reported in patients receiving medications for multidrug- and extensively-drug-resistant tuberculosis (MDR-TB & XDR-TB). However, there is little prospective data on AE in MDR- or XDR-TB/HIV co-infected patients on antituberculosis and antiretroviral therapy (ART) in programmatic settings.
Methods
Médecins Sans Frontières (MSF) is supporting a community-based treatment program for drug-resistant tuberculosis in HIV-infected patients in a slum setting in Mumbai, India since 2007. Patients are being treated for both diseases and the management of AE is done on an outpatient basis whenever possible. Prospective data were analysed to determine the occurrence and nature of AE.
Results
Between May 2007 and September 2011, 67 HIV/MDR-TB co-infected patients were being treated with anti-TB treatment and ART; 43.3% were female, median age was 35.5 years (Interquartile Range: 30.5–42) and the median duration of anti-TB treatment was 10 months (range 0.5–30). Overall, AE were common in this cohort: 71%, 63% and 40% of patients experienced one or more mild, moderate or severe AE, respectively. However, they were rarely life-threatening or debilitating. AE occurring most frequently included gastrointestinal symptoms (45% of patients), peripheral neuropathy (38%), hypothyroidism (32%), psychiatric symptoms (29%) and hypokalaemia (23%). Eleven patients were hospitalized for AE and one or more suspect drugs had to be permanently discontinued in 27 (40%). No AE led to indefinite suspension of an entire MDR-TB or ART regimen.
Conclusions
AE occurred frequently in this Mumbai HIV/MDR-TB cohort but not more frequently than in non-HIV patients on similar anti-TB treatment. Most AE can be successfully managed on an outpatient basis through a community-based treatment program, even in a resource-limited setting. Concerns about severe AE in the management of co-infected patients are justified, however, they should not cause delays in the urgently needed rapid scale-up of antiretroviral therapy and second-line anti-TB treatment

This document discusses the need for geriatric assessments (GAs) in older cancer patients undergoing treatment. GAs evaluate patients' functional status, medical conditions, cognition, nutrition, social support and medications. The document aims to analyze evidence on how GAs impact treatment decisions and patient outcomes. It describes how GAs may alter treatments in up to 49% of patients by identifying age-related vulnerabilities. Studies show GAs correlate with survival rates, quality of life and toxicity risks. While GAs provide useful information, more research is still needed on their optimal use in oncology.
This document summarizes a study on risk factors, health problems, reasons for admission, and knowledge of diabetes patients admitted to a hospital in Nepal. The study found that over half of patients were aged 40-60 years old, Hindu, and non-vegetarian. Many had complications like hypertension, eye and kidney problems. Patients had some knowledge of their disease but lacked understanding of causes, treatments, diet etc. There is a need for better health education programs to improve patient knowledge and care of diabetes in Nepal.

Abstract Background: Postoperative nausea and vomiting (PONV) refers to a problem commonly occurring after surgery. Acupuncture is considered a critical complementary alternative therapy for PONV. The acupoints selection critically determines the efficacy of acupuncture, whereas the selection rules remain unclear. The objective of the present study was to delve into the principles of acupoints selection for PONV using data mining technology. Methods: The clinical trials assessing the acupuncture effect for PONV were searched with the use of computer in PubMed, China National Knowledge Infrastructure, and Chinese Biomedical Database; the time span was confined as 2009–2019. The database of acupuncture prescriptions for PONV was built using Excel 2016; the description and association were analyzed by IBM SPSS modeler 18. Result: Eighty-three relevant literatures were screened out. The number of specific acupoints took up 72.5% of all acupoints; specific acupoints exhibited the frequency taking up 91.30% of the total frequency. As revealed from the result, Neiguan (PC 6), Zusanli (ST 36), Hegu (LI 4), and Zhongwan (CV 12) were most frequently applied, suggesting the tightest associations. Most acupoints were taken from the stomach meridian and pericardium meridian. The common acupoints were concentrated in the lower limbs, chest, as well as abdomen. Conclusion: Data mining acts as a feasible method to identify acupoints selection and compatibility characteristics. As suggested from our study, the acupoints selection for PONV prioritizes specific acupoints and related meridians. The selection and combination of acupoints comply with the theory of traditional Chinese medicine.
East to west: research progress in traditional Chinese medicine for antiaging...LucyPi1
Abstract Delaying the onset of aging is considered an important tool for dealing with the global crisis of the aging population. Accordingly, several antiaging studies have been conducted using strategies of modern medicine and traditional Chinese medicine (TCM). In this review, we summarize the current state of antiaging research related to both modern medicine and TCM and provide suggestions for further research. Various theories related to the aging process have been proposed, including the free radical theory, mitochondrial DNA damage theory, telomere theory, cross-linking theory, and intestinal flora theory, and a number of antiaging chemical treatments have been developed using modern medicine. These theories and achievements have resulted in major advancements in antiaging research. TCM is based on practical experience and has a long history with unique advantages in antiaging research. Some antiaging practices such as moderate diet consumption, acupuncture, Tai Chi (a traditional Chinese martial art that can relax the nerves to slow down the aging process), and Wuqin Xi (a traditional Chinese exercise to strengthen the body) have been adopted to maintain health. Several TCMs and prescriptions, particularly those related to medicine food homology, have been used in antiaging treatment, and their antiaging properties have been demonstrated to be effective based on pharmacological experiments and clinical applications.
The document discusses enhancing quality of life as an important goal for cancer treatment. It notes that while treatments have increased survival rates, they can also cause chronic health issues for survivors that reduce quality of life. More research is needed to better understand and prevent these toxic side effects, through identifying biomarkers and mitigation strategies. The authors call for increased priority and resources for quality of life research to both improve existing treatments and enable more patients to benefit from new therapies.
Herbal Medicine for Cancer Treatment: Main Force or Supplement_Crimson Publis...CrimsonpublishersCancer
The Estimated numbers of new cancer cases and deaths in 2020 will be an estimated. 1.8 million new cancer cases diagnosed and 606,520 cancer deaths in the United States and there were 17 million new cases of cancer worldwide in 2018 [1]. The four most common cancers occurring worldwide are lung, female breast, bowel and prostate. A person’s risk of developing cancer depends on different factors, including age, genetics, and exposure to some potentially known carcinogens and those which are believed to be carcinogenic. Some avoidable lifestyle factors including smoking can increase cancer risk. However, cancer risk factors are similar worldwide. Insufficient exercise, alcohol, imbalanced diet, and obesity, and various infections account for a considerable proportion of cancers worldwide. Prevalence of any one of the risk factors varies in different ethnic groups and can vary by region and country, which contributes to variation of cancer incidence rates of the common types of cancer worldwide.
Annual advances in traditional medicine for tumor therapy in 2019LucyPi1
Abstract Today, the treatment of tumors remains a difficult problem. Traditional medicine has been used to treat cancer in different countries worldwide. However, while traditional medicine is popular globally, it is not yet accepted by Western medicine as some of the ingredients and the mechanism of action for the therapeutic effect have not been fully elucidated. Thus, scholars studying traditional medicine in the treatment of cancer have strived to solve this problem. In this review, we summarized the research progress of several traditional medicines used as tumor therapies in 2019 from the PubMed database. Studies of tumors treated with traditional Chinese medicine (TCM) are popular worldwide and obtain the most attention, which attracts more researchers to this field. The anti-tumor effects of Chinese herbal medicine-derived phytochemicals, such as polyphenols, polysaccharides, saponins, and alkaloids were the new research targets for 2019. The anti-tumor effects of TCM formula such as Sijunzi decoction, and Xiaopi formula have attracted the most attention in the past year. In addition to TCM, we also focused on the anti-tumor studies of other traditional medicines, including Thai traditional medicine, traditional medicine in Sri Lanka, traditional African medicine, traditional Korean medicine, and traditional Japanese medicine.

WELLNESSAPPROACH
THE NUMBER OF INDIVIDUALS WHOSUFFER FROM COMPLEX CHRONICdiseases such as heart disease,
diabetes, cancer, and autoimmune
disorders is on the rise. The conven-
tional care provided by allopathic
medicine is oriented toward acute care
and the diagnosis of trauma or disease
of limited duration, such as a broken
limb or heart attack.
Medical physicians practicing in this
model typically prescribe drugs or
surgery with the goal of ameliorating
the immediate conditionand symptoms.
If, as a DC, you are frustrated by
watching your patients suffer from
chronic disease and be cycled through
the system of diagnosis and drugs
without improvement, Functional
Medicine (FM) can provide you with
powerful tools and strategies to help
your patients regain their health.
Why Functional Medicine?
The acute-care approach is ill-equipped
to handle the multifaceted issues that
accompany most chronic diseases. It’s
also a model that fails to address the
unique genetic background of each
individual. It also does not take into
account the impact of modern lifestyles
and environmental factors that can
lead to an increase in chronic diseases.
These factors include diet, exercise,
exposure to toxins, and stress. For
these reasons, most doctors are
unequipped to assess the underlying
causes of disease. They do not know
how to utilize diet, exercise, and
nutrition as preventive factors in
combating chronic disease.
From an allopathic perspective, FM
offers a novel approach and method-
ology to treating andpreventing chronic
diseases. From a chiropractic perspec-
tive, seeking to discover the underlying
cause of disease by examining how
structure impacts function is a foun-
dational principal for the profession.
By joining forces, either through
collaboration or in a more formal
integrative or multidisciplinary practice
setting, allopathic physicians and
chiropractors can help their patients
derive the greatest benefit from both
perspectives. Practitioners of FM
develop individualized treatment
programs that address the interaction
between the external environment and
the internal environment of the body,

Hepatocellular carcinoma (HCC) has always been a difficult medical problem for the increasing mortality rate. According to the World Health Organization (WHO), hepatocellular carcinoma (HCC) is the fourth-leading cause of cancer related deaths worldwide [1] and is considered as a highly refractory cancer. Surgery is the most effective treatment to HCC, but HCC is resistant to conventional chemotherapy. In recent years, immunotherapy has been attracting growing attention as a promising therapeutic method to HCC. Immunotherapies to HCC including chimeric antigen receptor T cells (CAR-T), immune checkpoint inhibitor and oncolytic virus have become research hotspots.

While In contrast, is their really enough antidotal evidence that suggest complementary and alternative medicine is more effective then mainstream medicine in the treatment of cancer? There is supported evidence that when remedies are properly used in homeopathic care, specific remedies have reversed the growth of cancer. Various forms of homeopathic therapy allow the patient to take control of their health while making small manageable changes without the huge cost. Alternative therapies open new options for patients without harmful side-effects. The interest in preventative health has encouraged society to explore outside of the mainstream field of medicine and the options of various therapies are now being considered. Is it possible for Homeopathic remedies to be the future treatment and care for cancer?
Complementary and Alternative Medicine (CAM)
Protocols
Treating the person and as a whole being (Mind, body and spirit).
The focus on engaging the inner resources of each individual as an active & conscious participate in their own well-being. Complementary and Alternative systems do not research into echelons the practitioner/healer is not above the one that is being healed. The relationship is on a continuum of mutuality where both walk step-by-step on the journey to healing (Koopsen and Young, 2009).
Historical events
Samuel Hahnemann noted the description of a remedy made from "Peruvian Tree Bark" (Cinchona) (Cuellar, 2006. p. 79). Hahnemann’s “The Organon of Medicine” was published from first edition in eighteen ten, and “The Organon of the Healing Art” in nineteen twenty-one which enhanced the influence of homeopathic theory significantly. (Micozzi, M, 2015)
Chronic Disease
Chronic illnesses refer to those illnesses that are usually not fully recovered from them once a person has them. (Burkholder, Nash, 2014). Chronic conditions can remain for life, it is important for those affected by them to understand their condition and related care in order to achieve the highest quality of life. (Eliopoulos, 2014, p.280, para 1)
CAM perspective
The law of Similars, Allow the body to heal itself (Micozzi, 2015, p.385 para, 6). Cam perspective is to define what is causing disharmony in the body, treat it, and then allow the body to heal itself. We live in an era when individuals can survive and have a high quality life being empowered with knowledge, having a support system, and having a positive mind frame. The healing approach is stimulated by information.

The document discusses the importance of studying pathology for nurses. It begins by defining pathology as the scientific study of changes in structure and function of the body due to disease. It then discusses how understanding pathology can help nurses in several ways. Specifically, it allows them to understand disease etiology and progression, perform early diagnosis, implement preventative measures, and provide more effective patient care and management. Studying pathology equips nurses with knowledge about various disease processes and helps them correlate clinical features with structural and functional changes in organs.

Abstract
The timely introduction and rapid development of precision medicine have provided strong theoretical support and
technical support for tumor research. The treatment methods have been developed from single to multiple; the
research technology has been transformed from macro to micro; the treatment drugs have been updated from
systemic chemotherapy to targeted therapy and immunotherapy, and cancer has changed from a highly lethal
disease to a "chronic disease". Based on the current international cancer research hotspots and treatment frontiers,
this paper takes stock from five aspects, namely, treatment methods, detection technology, new drug research and
development, information data and traditional Chinese medicine, with a view to "from the point to the surface",
"from the outside to the inside", and "the combination of Chinese and western", so as to explore the overall picture
of cancer treatment and research.
This document summarizes and critiques research on psychoneuroimmunology (PNI) and claims that psychological factors can influence cancer outcomes. It finds that PNI research often relies on weak study designs, ignores negative findings, and overstates small or insignificant positive results. Better designed studies find little evidence that stress influences cancer or that psychosocial interventions impact survival time. The document cautions against overinterpreting immune system changes without considering the system's complexity.

This document reviews different types of cancer treatments and analyzes the tumor microenvironment and its role in cancer progression and treatment effectiveness. It discusses how the tumor microenvironment, consisting of non-cancerous cells like fibroblasts and immune cells, interacts with tumor cells and affects their behavior and response to therapy. Monitoring changes in the tumor microenvironment using molecular and cellular profiles can help identify new targets for cancer prevention and treatment. The document then provides an overview of common cancer treatment methods like surgery, chemotherapy, radiation therapy, immunotherapy, hormone therapy, and targeted therapy, and discusses how the tumor microenvironment contributes to tumor heterogeneity and drug resistance.
Herbal and Synthetic Drug Combinations in Cancer Therapy A Reviewijtsrd
Cancer is one of the leading and most serious diseases in the current decade, every year millions of people die because of various kinds of cancers. Many aspects relate to the cause of disease besides heredity, food habits, smoking, nutritional behaviors, radiation etc. Cancer is a high mortality disease and the therapeutics for cancer, especially for cancer metastasis is still imperfect. The successful cancer treatment till now has been under study, only chemotherapy and radiation treatments are at times successful. Alternative and less toxic medication is very much in need towards the disease, the use of concepts of herbal medicine with synthetic drug could present better drug leads towards the inhibitory treatment of Cancer. Nature shows plethora of medicinal plants with anticancer and antioxidant activities which may suppress the disease completely. By applying combination therapy instead of monotherapy can lead to improved efficacy and reduced toxicity of the conventional method of treatments of cancer.

This document summarizes a meta-analysis that evaluated the efficacy and safety of Astragalus injection as an adjuvant treatment for colorectal cancer. Eight randomized controlled trials involving 583 patients were included. The analysis found that compared to Western medicine alone, Astragalus injection improved treatment efficacy, improved patient quality of life, reduced leukopenia, reduced neurotoxicity, and reduced nausea and vomiting. The quality of the included studies was acceptable. In conclusion, Astragalus injection can reduce toxicity and improve the efficacy of conventional Western medicine in treating colorectal cancer.
complementary and alternative medicine applications in cancer medicineLucyPi1
Abstract
Besides conventional medicine, many patients with cancer seek complementary and alternative medicine (CAM) as
an additional treatment option. Since the early 1970s, the use of CAM in cancer treatment has expanded worldwide.
CAM, as a tempting option, was used by patients with cancer mainly due to easy accessibility. Patients with cancer
used CAM to achieve better quality of life or to find a cure. As physicians are mainly unaware of CAM use by
patients, doctor-patient communication about CAM use should be brought to a higher level. To identify
circumstances in which CAM are preferred, further investigations are needed especially in biologically based
therapies. Clinical-based evidence for mind-body therapies have been established, so this type of CAM can be
recommended for patients with cancer during chemotherapy. Future studies are necessary to fill the gaps so that
CAM users, as well as medical experts, are in position to clearly determine all the benefits and disadvantages of the
mentioned therapy.

Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.

Traditional Chinese medicine is an accepted and integral part of clinical cancer
management alongside Western medicine in China. However, historically TCM
physicians were unaware of the chemical constituents of their formulations, and the
specific biological targets in the body. Through HPLC, flow cytometry, and other
processes, researchers now have a much clearer picture of how herbal medicine works
in conjunction with the immune system in cancer therapy. Among them, the regulation of
tumor-related T cells plays the most important role in modulating tumor immunity by
traditional Chinese medicine. Encouraging results have been well-documented, including
an increase in T cell production along with their associated cytokines, enhanced regulation
of Tregs and important T cell ratios, the formation and function of Tregs in tumor
microenvironments, and the promotion of the number and function of normal T Cells to
reduce conventional cancer therapy side effects. Chinese herbal medicine represents a
rich field of research from which to draw further inspiration for future studies. While
promising agents have already been identified, the vast majority of Chinese herbal
mechanisms remain undiscovered. In this review, we summarize the effects and
mechanisms of specific Chinese herbs and herbal decoctions on tumor related T cells.

INTRODUCTION
Traditional Chinese medicine (TCM) has utilized herbs and herbal extracts to treat a variety of
diseases and disorders for over 2000 years. Among these diseases, Chinese doctors have treated
masses and tumors through the prescription of various herbs and formulations to reduce symptoms
describing the etiology of cancer. As cancer is one of the leading causes of death in China (He J.
et al., 2005), significant resources have been devoted to study the effects of TCM alongside Western
medical treatments. Clinical and preclinical trials have demonstrated the efficacy of Chinese

of conventional cancer therapies, reducing toxicity, and
improving quality of life factors (Nie et al., 2016; Xiang
et al., 2019).
Cancer was first described during the Shang dynasty (6th
–
11th
century BC) where it was described as liú, tumor, or lump
(Liu et al., 2015; Xiao, 2018). Clinical manifestations were
described in medical literature as early as 400 BC with further
elucidation by Wei Ji Bao Shu in 1170 AD, and Yang S.Y. in 1264
AD (Hu et al., 2012; Li et al., 2013). But, it is in the classic text,
the Huang Di Nei Jing (HDNJ) or Yellow Emperor’s Inner
Classic, circa 250 BC, that the full clinical picture of cancer
is presented.
Today, TCM is an accepted and important part of cancer
treatment alongside Western medicine in China and is gaining
acceptance in the United States. (Liu et al., 2015; Ling et al., 2018;
Wang Q. et al., 2017; Xiang et al., 2019). Complementary
medicine has increased 30% in National Cancer Institute
(NCI) designated cancer centers, and acupuncture is
represented in 73% of those centers, herbal medicine in 66.7%
(Yun et al., 2017). Chinese herbs are typically used as an adjuvant
therapy, and research suggests the alleviation of clinical
symptoms, such as pain, and prolonged survival time of post-
operational, and advanced stage cancer patients (Zhang
et al., 2017).
Within TCM, treatment methods are inextricably linked to
pattern-differentiation (BIAN ZHENG). This differential
diagnosis is based on four distinct examination methods—
observation, palpation (Chinese pulse methods), interrogation,
hearing, and smelling. These diagnoses are dependent upon the
clinician’s subjective judgement and clinical experience, which
can induce considerable variability in clinical trials and evidence-
based research (Hsiao and Liu, 2010). Further, a western
diagnosis of cancer may present as a variety of TCM patterns
for which the clinician might devise a treatment plan (Ferreira
and Lopes, 2011; Jiang et al., 2012). As such, TCM treatments are
very specific and the emphasis is on individual therapy (Hsiao
and Liu, 2010).
TCM practitioners may consult with a patient’s oncologist in
devising a treatment plan; however, the TCM strategy may also
be conceived completely outside the biomedical treatment
program as TCM practitioners in the United States most often
work in private practice, removed from institutional settings
(NCCAOM.org). A typical TCM treatment would involve the
aforementioned differential diagnosis, followed by an
acupuncture protocol involving one or more needles designed
to strengthen the patient’s immune system, alleviate current side
effects resulting from chemo or radio therapy, and in some cases,
reduce masses (Lu et al., 2008). The specific acu-points used
would be determined by traditional functions and indications as
indicated in classical texts such as the Zhenjiu Da Cheng and the
Huangdi Neijing Ling Shu. The practitioner would then
determine if an herbal formula is suited to the patient’s
diagnosis. Once again, the formula chosen would be based on
differential diagnosis and classical Chinese medicine texts such as
the Shang Han Lun and Jin Gui Yao Lue. In some cases, TCM
practitioners may have advanced training through a doctoral
program or specialty centers, such as Memorial Sloan Kettering’s
Cancer Center, from which they may have additional sources for
choosing treatment protocols (mskcc.org).
As this review will demonstrate, several classical treatment
methods, such as QUXIE, HUOXUE TONGLUO, and QINGRE,
are widely used alongside FUZHENG in TCM herbal medicine
and cancer treatment. As shown in Figure 1, in addition to
directly inhibiting tumor proliferation and metastasis, all of these
methods have an impact on the immune environment of tumor
patients, especially the distribution and function of T
lymphocytes, and each method has its own characteristics and
emphases. Simply speaking, they are aimed at different
subgroups of T cells with different mechanisms of action.
Herbal treatments, dietary therapy, acupuncture, and
moxibustion have long been the standard form of treatment in
Chinese medical literature, and represent a rich resource for
future investigation.
METHODS
An extensive search was undertaken in PubMed/MEDLINE,
ScienceDirect, Ovid, PLoS, and Google using the keyword
search terms TCM, Chinese herbs, T cells, tumor regulation,
and cancer along with specific T cell descriptors, and both
individual Chinese herbs and formulas. We selected and
reviewed all relevant studies, both in vivo and in vitro, that
analyzed the relationships of various Chinese formulas, herbs,
and their constituents with T cells and cancer therapy over the
last 25 years (1994–2019).
TUMOR RELATED T CELLS AND THEIR
ROLE IN TUMOR PROGRESSION
Also called thymocytes (reflecting their development in the
thymus), T cells or T lymphocytes are developed from
hematopoietic stem cells in the bone marrow. They help
protect the body from infection and help fight cancer
(cancer.gov). A type of white blood cell, they search the body
for cells displaying antigens either from infectious organisms or
antigens arising from tumor cell mutations known as
neoantigens. When the T-cell receptor (TCR) of a cytotoxic T
cell recognizes and binds to an antigen, the T cell kills the cell
displaying that antigen (Sarkizova and Hacohen, 2017).
Normally, the body recognizes and destroys cancer cells via the
innate and acquired immune system, and their relative immune
effector cells via the process of immunosurveillance (Figure 2).
However, cancer cells may evade such immunosurveillance
through immunoselection and immunosubversion. Block and
Markovic (2009) suggest that multiple factors may disrupt
normal immune function including production of cell surface
molecules, cytokines, and growth factors by tumors in order to
promote their own progression (Ha, 2009). Tumor clones, which
Hoffman et al. Chinese Medicine and Tumor Immunity
Frontiers in Pharmacology | www.frontiersin.org April 2020 | Volume 11 | Article 492

3. may be more evasive to immune detection, emerge in a process
called immunoediting propelled by the selective pressures of
immunosurveillance (Gross et al., 2013).
As cancer develops in the human body the number of normal
T cells decreases, along with B cells and natural killer (NK) cells
(Noguchi et al., 2014). Further, the specific ratios between Th1
and Th2, CD4+
and CD8+
, and Th17 and regulatory T Cells
(Tregs) are essential in a healthy system, but as cancer develops,
these ratios are dysregulated. While previous anti-genetic
experience is essential in developing the body’s T cell
sensitivity, additional factors such as patient and tumor
genetics, and the microbiome all play essential roles as well
(Lanitis et al., 2017). As the immune system continuously
interacts with tumors it is essential to understand these
mechanisms in developing cancer therapies.
Pro-T Cells, Cytotoxic T Cells, and Effector
T Cells
Pro-T cells or CD3+
cells help to activate cytotoxic T cells (CD8+
naive T cells) and T helper cells (CD4+
naive T cells). These cells
are required for T cell activation, and are frequent targets of drug
development. CD8+
T cells (cytotoxic T cells) are T lymphocytes
that have the ability to recognize and kill cancer cells directly.
Many studies, as outlined below, have identified Chinese herbs
and formulations that promote CD8+
function and infiltration.
Furthermore, effector T cells respond to stimulus, acting locally
at sites of infection to either kill infected cells or to help other
cells eliminate pathogens (Molecular Biology, 2002), and are also
identified as targets for TCM herbal therapy.
T Helper Cells
CD4+
T cells (T helper cells) assist white blood cells in
eliminating pathogens as a part of our acquired or adaptive

macrophages, and aid the maturation of B cells into both
plasma cells and memory cells. T helper cells suppress and
regulate the immune response by secreting cytokines during
the immune response and may differentiate into Th1, Th2, Th17,
and others.
Th1cells are responsible for activating and regulating the
development of cytotoxic T cells (CTL). They regulate the
production of cytokines IFN-g and TNF-a, and activate
antigen-presenting cells (APC). The release of cytokines from
Th1cells activates death receptors on tumor cell surfaces leading
to their destruction (Knutson and Disis, 2005). Th1 cytokines
also include IL-1, IL-2, and IL-12. Further, Th1 cells induce
secretion of IL-1b and IL-6 in antigen-presenting macrophages,
and this collaboration leads to cancer cell death (Haabeth
et al., 2011).
Th2 cells are essential in facilitating protective type 2 immune
responses (producing cytokines IL-4, IL-5, and IL-13), such as
those that target parasites and facilitate tissue repair. However,
they also contribute to chronic inflammatory diseases, such as
asthma and allergies. Their anti-tumor effects and contributions
to tumor growth remain one of the more challenging
mechanisms within immunotherapy, and studies often focus
on the ratio between Th1 and Th2. Factors secreted byTh2 such
asIL-4, IL-10, and TGF-b play suppressive roles in tumor
immune microenvironment, and promote tumor recurrence
and metastasis (Guo et al., 2014).
Th17cells protect the body against pathogens as a part of the
acquired or adaptive immunity. In murine studies Th17cells
mediate the regression of tumors (Martin-Orozco et al., 2009).
However, they were also shown to promote the formation of
tumors when induced by colonic inflammation (Wu et al., 2009).
The mechanisms by which Th17 cells contribute to tumor
progression are not clear despite being identified in a wide
variety of human tumors including ovarian, gastric, prostate,
renal, and pancreatic cancers (Kim and Cantor, 2014). Studies of
Th17 are primarily concerned with inflammatory diseases, and
autoimmune disorders. Nonetheless, the results may help us
understand how the regulatory effects of Chinese herbs may be
useful in immunotherapy.
CD4+
CD8+
Cells and Memory T Cells
CD4+
CD8+
cells are double positive T cells that express both
CD4 and CD8 co-receptors. Memory T cells (TM, CD4+
/CD44+
)
are T cells that have had interaction with specific antigens or
cancer, and are able to mount a strong and rapid response to the
pathogen or cancer.
Regulatory T Cells
Regulatory T cells (Tregs) play an important role in regulating
the immune system, preventing autoimmunity, and moderating
inflammation. However, they also play a significant role in the
development and progression of cancer via the suppression of
tumor-specific immunity. As Tregs secrete a variety of
immunosuppressive cytokines, it is essential to investigate
strategies that reduce their regulatory influences while
enhancing anti-tumor immunity (Ha, 2009). It has been shown
that regulation of Treg cells can increase immune protection
from tumor-associated antigens that are expressed as self-
antigens (Kosmaczewska et al., 2008). Treg cells are
characterized by CD25 and Foxp3 mRNA, a protein involved
in immune responses, and the development of Treg cells.
Natural Killer Cells
Natural Killer cells (NK) are cytotoxic lymphocytes (white blood
cells) that behave like cytotoxic T cells. However, they do not
require antibodies or MHC to respond to harmful cells. NK cells,
also known as CD56+
, play a major role in detecting and
controlling early signs of tumors, and in killing virally infected
cells (immunology.org). NK cells also produce interferon-g,
which activates M1 and Th1 immune responses, thus indirectly
increasing cytotoxicity of cancer cells (Gross et al., 2013).
REGULATING EFFECTS OF TRADITIONAL
CHINESE MEDICINE ON TUMOR
RELATED T CELLS
The regulatory effects of Chinese herbal medicines on the
immune system of tumor-bearing organisms is commonly
accepted. As shown in Table 1, Chinese herbs and formulas
can play an important auxiliary role in the treatment of tumors
by affecting many kinds of T cells, including Pro-T cells, Tregs, T
helper cells, Cytotoxic T cells, and NK cells. The targeted T cells
and the mechanism of change often reflect the characteristics of
specific TCM treatment methods.
FUZHENG Combined with QUXIE
FUZHENG (扶正) therapy was developed in modern China, and
utilizes herbal formulations to protect and enhance the immune
system from the damage exerted by conventional therapies such as
chemotherapy and radiation on patients. Though similar in concept
to classical Chinese medicine tonification formulas (BUFA), it is the
addition of herbs to eliminate pathogens (QUXIE) that often makes
them unique in their category. The primary strategy of FUZHENG
formulas combined with QUXIE (eliminating pathogens) is the
positive regulation of overall immunity through the promotion of
normal T lymphocyte and macrophage function, and inhibition of
tumor immunosuppressive T cells such as Tregs. As FUZHENG
formulas are a modern creation utilizing Chinese herbs and
formulas, there is no historical record of these formulas. The
formula FUZHENG QINGJIE (FZQJ) is often used along with
chemotherapy in gastrointestinal cancer (Chen et al., 2017b). It was
found that FZQJ could alleviate chemotherapy induced stresses
including white blood cell and platelet destruction, and reduction of
CD3+
and CD4+
T lymphocytes. FZQJ could also help maintain the
concentration of hemoglobin, prevent the loss of body weight, and
increase serum TNF-a and IL-2 levels, thus alleviating the side
effects of chemotherapy (in this case cyclophosphamide or CTX).
Interestingly, while FZQJ was able to inhibit the development of
tumors on its own, its effects were more pronounced when used
with CTX. How this occurs is still poorly understood; however, the
authors suggest that the elevated levels of TNF-a (perhaps triggered

5. by IL-2) may activate apoptosis via mitochondrial mediation and
Bcl-2 family proteins.
Another Chinese herbal formula used in FUZHENG therapy,
FUZHENG FANGAI pill (FZFA), has been shown to have few
side effects with moderate but persistent efficacy. FZFA contains
Codonopsis pilosula (tangshen, 15g), Astragalus mongholicus
(huang qi, 30g), lycii fructus (gouqizi, 12g), Polygonum
multiflorum (he shou wu, 12g), bistort root (quanshen, 10g),
and Chinese Actinidia root (tenligen, 12g). Liu et al. (2014)
demonstrated that FZFA along with cyclophosphamide could
restore the ratio of spleen lymphocytes such as CD4+
, and their
associated cytokines IL-17, Th17, CD4+
CD25+
, and Foxp3+
Treg
cells while inhibiting the inflammatory response. Remarkably,
the ratio of Th17 to Treg cells approached normal ranges with
this combination. Like FZQJ above, FZFA administered with
CTX inhibited tumor growth and metastasis, and could improve
survival rates while increasing life span, compared with the
administration of CTX alone (Liu et al., 2014).
FUZHENG YILIU Decoction (Radix ginseng (ren shen),
Radix astragali (huang qi), Ganoderma lucidum (lingzhi),
Angelica sinensis (dang gui), and Lycium chinense (gou qi zi)),
remarkably inhibited the proliferation of hepatoma cells, and
induced apoptosis in vivo by promoting the production of Th1
cytokine IL-2 (Chen et al., 2014). A number of studies
demonstrating FUZHENG Yiliu’s effects on hepatoma cells
have been published showing an increase in CD3+
, CD4+
and
NK cells in peripheral blood with an increase in IL-2 and TNF-a,
thus inhibiting hepatocellular cancer proliferation (Cao et al.,
2011; Cao et al., 2012).
In a meta-analysis of 8 trials utilizing SHEN QI FU ZHENG
Injection (SFI), Xu et al. (2017) found that the formula consisting
of Codonopsis (dang shen) and Radix astragalus (huang qi) could
improve chemotherapy outcomes, and improve immune function,
upregulating CD3+
, CD4+
, CD4+
/CD8+
, and NK+
cells. They also
found that SFI could reduce adverse side effects such as
leukocytopenia, thrombocytopenia and gastrointestinal toxicity

6. (Xu et al., 2017). Though the meta-analysis pointed out the
shortcomings of the included trials (the small sample size was
772, and lacked double-blind controls), it did provide encouraging
results that warrant larger, better quality clinical trials.
Li et al. (2013) demonstrated that an injection of the herbal
formula XIAO AI PING (Marsdenia tenacissima, tong guan
teng) in combination with Cisplatin promotes both the
infiltration and the function of CD8+
T cells, thus reducing
tumor growth and promoting the apoptotic effects of cisplatin in
Lewis lung cancer cells. XIAO AI PING was also found to
increase the infiltration of cytotoxic T lymphocytes CD8+
T
cells (Li et al., 2013). XIAO AI PING was shown to target
proliferating cell nuclear antigen (PCNA) and phosphorylated
Akt, both markers for tumor growth, and increased levels C/EBP
homologous protein (CHOP), a marker for tumor cell apoptosis.
The study concluded that XIAO AI PING used in combination
with cisplatin was more effective than either formula or
chemotherapy alone. A 2019 systematic review and meta-
analysis confirms this data. Wu et al. (2019) compared data
from 14 studies between 2009 and 2018 utilizing a variety of
chemotherapy protocols including XELOX (capecitabine and
oxaliplatin), SOX (S-1 and oxaluplatin), and others in
combination with XIAO AI PING. They concluded that the
combination could offer an effective treatment strategy for gastric
cancer patients, especially with the XIAO AI PING and XELOX
pairing. They reported a reduction in leukopenia, liver and renal
damage, and reduced incidence of erythrodysesthesia or hand-
foot syndrome.
The formula FEI YANNING Decoction [Radix astragali
mongolici (sheng huangqi) 40 g, Rhizoma atractylodis
macrocephalae (baizhu) 15 g, Succys bufo skin (gan chenpi) 9
g, Nidus vespae (fengfang) 9 g, Rhizoma paridis (qiye yizhihua)
15 g, Rhizoma polygonati sibirici (huangjing) 30 g, Herba
epimedii brevicornus(xianlingpi) 15 g, Ganoderma lucidum
(lingzhi) 30 g] has undergone several studies related to cancer
(Wang et al., 2009; Guo et al., 2012; Wang et al., 2012; etc.).
Specifically, FEI YANNING (FYN) decoction was found to
reduce Treg cells in the spleen and thymus, and in tumors
along with significantly downregulating Foxp3 mRNA. These
results suggest that FYN may be used as an adjuvant treatment to
improve chemo and radiotherapy treatment, as well as
anticancer vaccines.
BUFA (Formulas and Herbs That Tonify)
BUFA formulas promote the proliferation and function of T cells
and other immune positive regulatory cells through a variety of
mechanisms. Important herbs that have been studied with regard
to BUFA include Radix astragalus (huang qi), and its ability to
enhance the immune system (Denzer et al., 2006); Atractylodes
rhizome (bai zhu), which increases lymphocyte proliferation and
stimulates the immune system (Son et al., 2017); and Radix
codonopsis (dang shen), which increases red blood cells and
assists in T cell formation (He et al., 2015b). Additionally,
American ginseng or Panacis quinquefolii radix (xi yang shen)
has been found to inhibit cancer of the liver (Qu et al., 2018),
colon (Yang et al., 2016), and breast cancer (Yonghe, 2004).
Chinese ginseng or Radix ginseng (ren shen) has been intensely
studied as an athletic performance enhancer, and as an
immunomodulator. Radix ginseng has also been found to have
inhibitory effects on prostate cancer, hepatic carcinoma,
glioblastoma, and other malignant tumors (Wang et al.,
2017b). One of its constituents, ginsenoside Rh2, has been
found to enhance the antitumor immunological response by
increasing tumor infiltration by T lymphocytes.
The Chinese formula XIAOJI has been shown to increase
both CD3+
and CD4+
cells after treatment in patients with
suppressed immune systems as a result of non-small cell lung
cancer. The formula contains several tonifying herbs: Astragalus
mongholicus (huang qi), Coriolus versicolor (yun zhi), Psoralea
corylifolia L. (bu gu zhi), along with herbs to clear heat and drain
damp including Hedyotis diffusa (bai hua she she cao), Curcuma
kwangsiensis (jiang huang), Scorpion (quan xie), Centipede (wu
gong), and Rhubarb (da huang). Li et al. (2015) combined the
formula with chemotherapy, and a transfusion of cytokine
induced killer cells. Patients with this combined therapy had
greater progression free survival rates, higher disease control
rates, and there were no significant side effects. Li also noted that
in their studies XIAOJI increased lung cancer cell apoptosis, and
inhibited tumor cell growth and metastasis (Chai et al., 2014).
Zhang et al. (2018) found that Cistanche deserticola (rou cong
rong), when used as a replacement for alum as an adjuvant,
enhanced the proliferation of T and B cells, the production of
IFN-g and IL-4 in CD4+
T cells, and the expression of IFN-g in
CD8+
T cells. Remarkably, the extraction also down-regulated
Tregs, while up-regulating levels of both CD40 and CD80,
signaling proteins found on the surface of antigen presenting
cells, dendritic cells, B cells, and monocytes. Though this study
demonstrated the use of cistanche as an adjuvant, it provides
evidence that the polysaccharides of the herb enhance humoral
and cellular immunity, and should be further investigated.
Wang et al. (2017a) found that polysaccharides from Epimedium
koreanum nakai (yin yang huo), a Chinese tonic herb, could
substantially increase macrophage activity in Lewis Lung
Carcinoma-bearing mice. The results of this activity enhanced
CD4+
differentiation, and increased immunomodulatory cytokines
(IFN-g) thus inhibiting the growth of tumors. These antitumor
activities achieved host-immune regulation, and an increase in the
antigen presenting function of dendritic cells.
Lycium barbarum (gou qi zi), an herb used to nourish the
blood and mentioned earlier as a component of FUZHENG
FANGAI pill, showed similar effects in an additional study (He
Y. L. et al., 2005). Cao et al. (1994) found that Lycium barbarum
polysaccharides (LBP), one of the primary constituents of gou qi
zi, significantly increased the response rate and effectiveness of
NK cells in advanced stage cancer patients. More recent studies
demonstrated that LBP significantly increased CD4+
and CD8+
as compared with the control groups to reduce
immunosuppression in H22-bearing mice, and that LBP can
enhance the immune system and inhibit tumor growth (Bo et al.,
2017; Deng et al., 2018; Wang et al., 2018a). In addition, goji
reduces inflammation via regulation of the NF-kB pathway and
has been shown to inhibit the growth of colon (Mao et al., 2011),

gastric cancer (Cheng et al., 2014).
DANG GUI BU XUE TANG (DGBXT) is a Chinese herbal
formula consisting of two herbs, Radix astragali (huang qi) and
Angelicae sinensis radix (dang gui), and is used to nourish blood
and improve overall energy levels, especially in post-partum
women. Interestingly, after just 3 weeks of oral administration,
Hsieh et al. (2003) found that DGBXT “increased the population
of cytotoxic T lymphocytes and NK cells,” while down-regulating
T helper cells (CD4+
/CD25+
) in both the spleen and in tumor-
draining lymph nodes. The study also demonstrated that
DGBXT also increased the production of TNF-a. Chen et al.
(2017) found that DGBXT could also inhibit colorectal cancer
(CT-26) through autophagic processes, or cell degradation. The
mechanism, LC3B lipidation, downregulation of phospho-
p70s6k
, and upregulation of Atg7, was elucidated further in vitro.
Ganoderma lucidum or Reishi mushroom (língzhī) has
traditionally been used to calm the spirit in TCM, and has
been known as a longevity herb for centuries. Modern research
has touted numerous health benefits related to its
polysaccharides and triterpenes including strengthening the
immune system, and enhancing T cell and macrophage
function (Wachtel-Galor et al., 2011). It has also been shown
to reduce the side effects of chemo and radiotherapy (Gao et al.,
2003; Kladar et al., 2016; Jin et al., 2016). In another study (Li A.
et al., 2015), Ganoderma lucidum polysaccharides(GLPS)
significantly inhibited tumor growth in hepatoma-bearing mice
by increasing the ratio of T effector cells to Tregs. GLPS also
increased IL-2 secretion, thus eliminating the suppression of T
effector cells by Tregs. GLPS also inhibited Foxp3 mRNA
expression, but in this study they further demonstrated that
this occurred through an increase of miR-125b expression.
Zhang et al. (2019) found similar results with Ganoderma
lucidum polysaccharides combined with gold nanocomposites
(GLP-Au). They found that the combination increased DC
activation which resulted in the proliferation of CD4+
and
CD8+
, and when combined with the chemotherapy drug
doxorubicin, GLP-Au increased CD4+
/CD44+
T cells. In a
clinical trial of advanced stage cancer patients, Gao et al.
(2003) prescribed an extract of Ganoderma lucidum. After 12
weeks of oral administration they found increased levels of
CD56+
(NK cells), plasma IL-2, IL-6, and IFN-y, along with
decreased levels of IL-1 and TNF-a. Additionally, CD3+
(T
lymphocytes), CD4+
(T helper cells), and CD8+
(T suppressor
cells) showed increased levels. Chang et al. (2014) noted that
Ganoderma lucidum stimulated the secretion of perforin and
granulysin, granule proteins with lytic properties that increase
NK cell cytotoxicity. However, in a Cochrane review (Jin et al.,
2016), researchers noted that Zhang et al. (2000) found a
negative impact on NK cell activity with ganoderma
administration; however, this study is only available in Chinese
and not available for verification.
Glycyrrhiza uralensis, licorice root (gan cao) is an herb used in
many traditional Chinese herbal formulas to moderate and
harmonize the characteristics of other herbs (Bensky et al.,
2004). Ayeka et al. (2017) found that the polysaccharides of
Glycyrrhiza uralensis significantly suppressed the growth of
tumors in CT26 tumor bearing mice while activating CD4+
and CD8+
. This activation of CD4+
and CD8+
increased
cytokine production, specifically IL-2, IL-6, IL-7, and decreased
TNF-a levels. Ayeka’s previous study (2016) also showed
benefits from Glycyrrhiza uralensis polysaccharides on
inhibiting carcinoma cell growth and upregulation of IL-7 in
vitro. A recent study (Guo et al., 2015) showed that an extract of
licorice root increased production of Foxp3+
regulatory T cells
“after stimulation of purified naive (CD4+
CD25−
) T cells by CD3
and CD28 antibodies, and transforming growth factor-beta
(TGFb).” Furthermore, T cell proliferation and survival may be
compromised by licorice as it reduces levels of Th1 cytokine IL-2.
While Regulatory T cells are crucial in the prevention and
regulation of inflammatory diseases, their immuno-suppressive
actions are counterproductive in the treatment of cancer.
Therefore, contradicting Ayeka et al.’s findings, the use of
licorice extracts might be contraindicated despite its ability to
enhance T helper cells.
Siberian ginseng, radix et caulis acanthopanacis senticosi (ci
wu jia), is a qi tonic in Chinese medicine that is primarily used to
strengthen the body, invigorate the blood, and improve
concentration or even alleviate mild depression. Studies by
Szolomocki et al. (2000) found that the herb positively affected
physical fitness and lipid metabolism while stimulating T
lymphocytes and natural killer cell production. Lau (2019)
demonstrated that the primary active constituents from A.
senticosi include the polysaccharides and glycopolysaccharides
which stimulate or enhance T cells, cytotoxic cells, and NK cells.
Lau further suggests that it is the whole-herb aqueous extract of
A. senticosi, not extracted constituents, that may yield the most
promising mechanisms for investigation.
Treatment with ACML-55 (Ma et al., 2008), a standardized
extract of American ginseng or Panacis quinquefolii radix (xi
yang shen), showed increased CD8+
T cells, and increased
activation of innate lymphocytes, including NK cells and
gamma-delta T cells (gd). The study showed that the immune
response was able to significantly delay tumor development in
colon cancer-bearing murine models, and indicates that ACML-
55 increases the antitumor response of both our adaptive
immune system, and our innate immune system.
Wang and Chen (2009) observed that patients with
esophageal squamous cell carcinoma (ESCC) receiving
radiation therapy had significantly lower expressions of Th1
type transcription factor T-bet and cytokines IFN-g and IL-2,
while expressions of Th2 type transcription factor GATA-3 and
cytokines IL-4 and IL-10 were significantly higher. However,
using Aidi injection (Mylabris (ban mao), Radix ginseng (ren
shen), Radix astragali (huang qi), and Radix et caulis
acanthopanacis senticosi (ci wu jia)) during radiotherapy the
Th2 factors were inhibited, suggesting that this herbal extract
may reverse the Th2 predominant status (Wang and Chen, 2009).
A retrospective study by Gang et al. (2018) further suggested that
Aidi injection could be used along with chemotherapy to
significantly improve Quality of Life (QoL) scores for a variety
of cancers, including gastric, lung, breast, colorectal, cardiac and
Hoffman et al. Chinese Medicine and Tumor Immunity

8. esophageal cancers, liver and ovarian cancer. This extensive
study included 3,200 patients and further supported findings
that Aidi injection could increase CD3+
, CD4+
, CD8+
, NK cells,
and the ratio of CD4+
/CD8+
, and Th1/Th2, thus enhancing
cellular immunity.
QINGRE (Formulas and Herbs That Clear
Heat)
QINGRE (清热–Formulas that Clear Heat), one of the eight classical
treatment methods (BA FA, 八法) in TCM, seeks to clear heat in the
body in order to eliminate pathogens. From a biomedicine
perspective, these herbs and formulas are considered antipyretic
and anti-inflammatory, and may have antibacterial, antiviral, and
antifungal effects (Chen and Chen, 2004, p. 105). A recent study
(Huang et al., 2016) investigated the use of Rehmannia glutinosa
polysaccharide liposome (RGPL), a standardized extract of the
unprepared form of rehmannia (sheng di huang). Rehmannia
glutinosa is traditionally used in TCM to clear heat from the
body, and nourish fluids in cases of high or continuous low-grade
fever, thirst, dry mouth, and constipation. In TCM, these symptoms
would most commonly be associated with warm pathogenic
diseases, diabetes, and in a modern context, the side effects of
chemo and radiotherapy. The study found that RGPL significantly
increases the percentages of central and memory cells, and effector
memory cells in murine models. Of particular interest in the study
was the encapsulation of RPG within a liposome in order to reduce
the rate of metabolism, and therefore extend its duration of action
within the body. The study demonstrated that the RGPL not only
increased antigen-specific immune responses, but also triggered
dendritic cell (DC) activation and immune memory. DC’s are
antigen presenting cells (APC) with high levels of cell surface
receptors whose main function is to capture and process antigens
(Melief, 2003). The study demonstrated the upregulation of DCs,
and allogenic T cell proliferation while strengthening antigen
presenting functions. Though the study was primarily looking at
RGPL as a vaccine adjuvant, the results provide a mechanism for
increased antitumor and antiviral immune responses, and warrant
further study of this important herbal extract.
A study conducted by Ip et al. (2017) found that anemoside
A3 (AA3), a triterpenoid constituent of Pulsatilla chinensis (bai
tou weng), inhibits Th17 cell differentiation, and reduced both
Th1 and Th17 inflammatory responses. While this study
measured the immunomodulatory and neuroprotective effects
of AA3 in MS, its findings elucidate the effects of AA3 on the
immune system, and the mechanisms by which it may help
restore homeostasis via the downregulation of these
inflammatory cytokines (Th1 and Th17).
Scutellaria baicalensis (huang qin) has been studied extensively,
and a variety of mechanisms have been discovered. These include
inhibition of PGE2 synthesis and G0, G1, G2, and S phase arrest.
Scutellaria also has neuroprotective and hepatoprotective affects
(Wang et al., 2018b). In TCM, it is said to clear heat from the body
and is typically used to eliminate toxins. Wogonin, a flavonoid-like
chemical compound found in Scutellaria, was found to induce
apoptosis of tumor cells via DC’s, and to promote NK, DC and T
cells in tumor tissue (Nie et al., 2016, and Xiao et al., 2015).
Baicalin, a flavonoid found in Scutellaria baicalensis, significantly
decreases inflammatory mediators such as TNF-a, IL-1B, and in
Th1 related cytokines such as IL-12 and IFN-g in rats with TNBS-
induced ulcerative colitis (Zou et al., 2015). Baicalin also reduces
the number of Th17 cells and their associated cytokines, IL-17 and
Il-6. Zou states that the effects of baicalin are associated with the
regulation of Th17 and Tregs. It is this ratio of Th17 to Treg that
may be the mechanism with which baicalin reduces inflammation,
and could lead to further research in the regulation of the
tumor microenvironment.
In an older study, Yoshida et al. (1997) found that extracts of
Oldenlandia diffusa (bai hua she she cao) enhanced the induction
of alloantigen specific cytotoxic T lymphocytes, and stimulated
murine spleen cells. Oldenlandia diffusa is used in TCM to clear
heat and eliminate toxins, and as such is often used in herbal
formulas to treat cancer in China. Studies consistently show its
pro-apoptotic effects via caspase-dependent apoptosis and other
mechanisms (Gupta et al., 2004; Yadav and Lee, 2006; Willimott
et al., 2007; Yang et al., 2010).
Musca domestica (MDPF, also known as wugu chong), the
larvae of domestic houseflies, has been used in China for cancer
treatment along with osteomyelitis, decubital necrosis, and other
diseases. Sun et al. (2014) found that oral administration of MDPF
for 10 days could not only inhibit the growth of S180 sarcoma, but
also enhance splenocyte proliferation, and both NK cell and CTL
activity from the splenocytes. Furthermore, MDPF significantly
promoted Th1 transcription factors T-bet and STAT-4 in
splenocytes, while enhancing Ig2, IgG2a, and IgG2b antibody
levels. Sun et al. speculated that MDPF may trigger Th1 specific
cell-mediated immunity. Previous studies showed that MDPF
inhibited bacterial pathogens such as e.coli, and inhibited tumor
growth in human colon cancer CT26 cell lines (Hou et al., 2007).
Artesunate (ART), is an artemisinin based compound derived
from Artemisia annua (huang hua hao), an herb that is
traditionally used to treat malaria as an anti-inflammatory and
antifebrile medicinal. A 2014 study showed that ART was capable
of inhibiting orthotopic tumor growth in human cervical cancer
cells while decreasing Foxp3 expression in T cells, and facilitated
the reduction of Tregs (Zhang et al., 2014). The study demonstrates
that ART may be effective for use in the treatment of cervical cancer
utilizing immunotherapy. Another study utilized ART as an
adjuvant treatment in esophageal cancer with radiotherapy (Fei
et al., 2018). It was found that administration of ART inhibited
esophageal cancer cell growth (TE-1 cell line), and increased the
sensitivity to radiotherapy. Interestingly, pretreatment with ART
enhanced the apoptotic effects of radiotherapy, and downregulated
or reversed radiation induced G2/M arrest, the process by which
damaged cells are not able to initiate mitosis.
HUOXUE TONGLUO (Formulas and Herbs
That Promote Blood Circulation and
Remove Obstructions)
Herbs and formulas to promote blood circulation and remove
obstructions from the collateral channels (HUOXUE
TONGLUO, 活血通络) may also be included in TCM cancer
treatment. HUOXUE TONGLUO herbs may dilate blood
Hoffman et al. Chinese Medicine and Tumor Immunity

9. vessels, and have anticoagulant and antiplatelet effects. They may
also provide analgesic and anti-inflammatory effects (Chen and
Chen, 2004, p. 612). Ligusticum chuanxiong is one of the primary
herbs used in TCM to improve blood circulation. Wei et al.
(2003) found that a preparation of the herbs Radix astragali
(huang qi), and one of the primary constituents of Ligusticum
chuanxiong (chuan xiong), tetramethylpyrazine (TTMP), could
enhance levels of Th1 cytokines (IFN-g and IL-2), and reduce Th2
cytokines in cultured peripheral blood mononuclear cells
(PBMC) of lung cancer patients. Additional studies showed
that the polysaccharides of Radix astragali reduced the
percentage of Th2 cells along with Tregs, and restored the ratio
of Th1 and Th2 (Hou et al., 2015).
Chang et al. (2011) found that extracts of Carthamus
tinctorius (hong hua), another important herb used to increase
blood circulation in TCM, increased production of cytotoxic
CD8+
T cells while also enhancing dendritic cell cancer vaccines.
In the study, a Carthamus tinctorius (CT) treated DC vaccine
also stimulated splenic T lymphocytes to secrete IFN-g and IL-
10, and heightened expressions of CD86, MHC-1, and MHC-II
antigen-presenting cells. Studies have further demonstrated the
antitumor effects of CT polysaccharides (Wakabayashi et al.,
1997; Ando et al., 2002; Shi et al., 2010).
In another study by Chueh et al. (2015), a crude extract of
Polygonum cuspidatum (hu zhang) was found to promote
natural killer cell activity of splenocytes, and promoted B cell
proliferation at specific doses (200 mg/kg), but did not promote
T cell proliferation in leukemic mice. Polygonum cuspidatum is
typically used in Chinese medicine as a laxative due to the natural
presence of emodin. Recent studies have focused on its
resveratrol content, though Kimura and Okuda (2001) note
that resveratrol has no effect on the levels of CD4+
, CD8+
, or
NK cells.
Further, Tripterygium wilfordii or Thunder God Vine (lei
gong teng) has had an almost meteoric rise in research circles for
its positive effects on arthritis, and in fighting cancer. The herb is
used in Chinese medicine to increase blood circulation and
remove obstructions (HONGXUE TONGLUO), but rarely as it
has potential toxic side effects (Chen, 2004; Zhao et al., 2015).
More than 100 different compounds have been isolated from
Tripterygium wilfordii (Liu et al., 2011), and research aimed at
understanding their actions is underway. One such study
suggests that leukemic T-lymphocyte apoptosis is induced by
triptolide, a diterpenoid epoxide, and is related to cell cycle G1
phase arrest (Zhang et al., 2015).
XUEBIJING (XBJ) injection is commonly-used to treat sepsis
and septic shock. The formula contains five Chinese herbs, Radix
Angelicae Sinensis (dang gui), Rhizoma Chuanxiong
(chuanxiong), Radix Paeoniae Rubra (chi shao), Radix Salviae
Miltiorrhizae (dan shen), and Flos Carthami (hong hua). From a
TCM perspective, XUEBIJING was derived from Xuefu zhuyu
decoction, and invigorates blood circulation, dispels stasis, cools
and detoxifies blood. In a meta-analysis and systematic review,
Chen et al. (2018) found that XBJ could inhibit inflammation
through the regulation of Tregs and Th17, and reduced
inflammatory cytokines TNF-a and IL-6. In another study,
Jiang et al. (2013) identified the constituents by which the
inflammatory process was downregulated via the NF-kB
pathway by senkyunolide I, safflor yellow A, oxypaeoniflorin,
and benzoylpaeoniflori (Jiang et al., 2013). Though these studies
demonstrate the use of XBJ to reduce sepsis and septic shock, the
mechanisms by which they operate via T cells encourage further
research and investigation.
Several studies have shown the efficacy of YUNZHI-
DANSHEN decoction (Wong et al., 2005; Bao et al., 2006; Saleh
et al., 2017). This simple formula consists of Coriolus versicolor
(yun zhi, commonly called Turkey Tail mushroom), and Salvia
miltiorrhiza (dan shen). Yun zhi is traditionally used in TCM to
promote the immune system, while dan shen is typically used to
improve circulation. Wong et al. (2005) found in a clinical trial of
post-treatment breast cancer patients that yunzhi-danshen
decoction could significantly elevate CD4+
T cells along with B-
lymphocytes after just 6 months of oral administration. The
formula also improved the ratio of CD4+
/CD8+
. Further,
plasma sIL-2R (a membrane receptor) concentration was
significantly reduced, showing that consumption of yunzhi-
danshen decoction orally can promote immune function and
response in post-treatment breast cancer patients. Interestingly,
YUNZHI-DANSHEN decoction was also effective in reducing
lymphopenia during radiotherapy of nasopharyngeal carcinoma
patients during a 16-week trial (Bao et al., 2006).
XIAFA (Formulas and Herbs That Drain
Downward)
XIAFA, another classical treatment method in TCM eight
methods, cleanses the intestines and stomach, so that the
pathogenic factors can be removed from the body, such as
food, dry excrement, excess heat, cold accumulation, blood
stasis, phlegm knot, and effusion. Lectin-55 is an active
constituent of Chinese mistletoe (hu ji sheng or herb visci). It
is primarily used in Chinese medicine to dispel or drain damp,
terminology often used to describe symptoms of rheumatoid
arthritis, and soreness/weakness of the tendons in the low back
or knees. Ma et al. (2008) demonstrated herb visci’s ability to
enhance CD4+
and CD8+
T cell proliferation in colon cancer,
and were able to demonstrate increased production of both
antigen-specific CD8+
T cells, and cytokine IFN-g. Lectin’s
represent an important focus in cancer research as they are
present in many plant species, and may increase both apoptosis
and autophagy (Yau et al., 2015).
Natural Killer cells can be promoted with an extract of
Solanum lyratum (bai ying). A traditional herb used to clear
heat and dampness from the body, it is now used to regulate the
immune system and treat allergies. Liu et al. (2011) found that
the main active fraction, n-butanol extract (BESL), promoted NK
cell, and CTL activity while significantly inhibiting the growth of
S180 sarcoma transplanted mice. BESL also promotes splenocyte
proliferation, and in turn increases IL-2 and IL-y production
improving the immune response. Guan et al. (2013) confirmed
Solanum lyratum’s immunomodulatory effects, and its ability to
inhibit the growth of tumors in S180 sarcoma transplanted mice.
Additional studies by Yang et al. (2010) showed that Solanum
Hoffman et al. Chinese Medicine and Tumor Immunity
Frontiers in Pharmacology | www.frontiersin.org April 2020 | Volume 11 | Article 492
9
10. lyratum could increase both macrophage and natural killer cell
activity in murine models bearing WEHI-3 murine leukemia
cells, and may act as an anticancer agent in patients (Yang
et al., 2012).
Further studies suggest that Liqi, another traditional herbal
formula used for centuries in China to treat cancer, increases the
activity of both NK cells and TNF-a, while increasing IL-2 activity
andproduction(Jietal.,2009).LiqiwasalsoeffectiveinregulatingT
lymphocyte subpopulations, and inhibited Lewis lung carcinoma
metastasis. The formula consists of Poncirus trifoliate (L.) Raf (zhi
ke), Akebia Trifoliate Koidz (san ye mu tong), Citrus medica var.
sarcodactylis Swingle (fo shou), and Saussurea lappa (yun mu
xiang), and contains a wide variety of active constituents
including coumarins, flavonoids, terpenoids, triterpenes and
triterpenoids, polysaccharides, and sesquiterpenes.
HUATAN (Formulas and Herbs That
Transform Phlegm)
Phlegm, an accumulation of damp, is often a part of the TCM
diagnosis related to cancer as phlegm is considered a primary
cause of masses in the body. Cai et al. (2011) found that
Trichosanthes kirilowi (gua lou), an herb used to transform
and remove damp phlegm in TCM, increased the percentage
of effector T cells, including CD4+
and CD8+
T cells which
produce cytokine interferon-gamma (IFN-g). The increased
immune response to tumor growth occurs via the interaction
between tumor suppression in lung cancer 1 (TSLC1) and class
1-restricted T cell-associated molecule (CRTAM), and results in
inhibited cell proliferation and increased apoptosis. Interestingly,
Trichosanthes kirilowi has been shown to augment Th2 cells, and
to induce HLA-associated immune suppression in bone marrow
derived cells, and to decrease CD3+
CD8+
T cells in the lymph
nodes and spleen of naive mice although Cai et al. demonstrated
this was not the case in tumor-bearing mice.
XI FENG (Formulas and Herbs That
Extinguish Wind)
XI FENG means extinguish wind, this method normally uses
animal derived proteins or alkaloids to remove pathogenic
factors. Zhao et al. (2012) found that polysaccharides from
centipede, Scolopendra subspinipes (wu gong), could also
increase the percentage of CD4+
, B cells, and NK Cells, while
regulating the ratio of Th1 and Th2 cytokines in sarcoma S180
bearing mice, thus inhibiting the growth of S180. Scolopendra
subspinipes is typically used in TCM to stop tremors and spasms,
but is also used to attack toxins in the body and dissipate nodules.
The same study revealed that Scolopendra subspinipes
polysaccharides also prolonged the survival time of hepatoma
H22 bearing mice. Ma et al. (2014) further elucidated the effects
of Scolopendra subspinipes on cancer cells, specifically A375
human melanoma cells, finding that the extract could inhibit
cell growth at the DNA synthesis phase (S-phase), and induce
cell apoptosis. And Ding et al. (2016) repeat this finding of cell
cycle arrest and apoptosis in their investigation of human glioma
(U87) cancer cells with isoquinoline alkaloids 1-2 isolated from
Scolopendra subspinipes.
CONCLUSION AND PERSPECTIVES
The vast majority of traditional Chinese medicine formulas are
extracted from one or more medicinal herbs with multiple
bioactive constituents. Understanding these constituents, their
interactions, and biological pathways is key to not only
developing targeted cancer therapies but also to create a bridge
between allopathic and TCM practitioners.
FU ZHENG therapy and other herbal treatment methods can be
beneficial when used in conjunction with conventional cancer
treatments (Nie et al., 2016; Xiang et al., 2019). However, TCM
herbal therapy, personalized cancer therapy, and immunotherapy
strive to enhance a cancer patient’s own ability to fight cancer. As
these therapies gain a stronger foothold in cancer treatment
strategies (especially T cell-based therapy), Chinese medicine
practitioners are presented with a unique opportunity to improve
TCM’s mainstream role in clinical cancer management. Moreover,
TCM differential diagnosis may be used as a significant tool to
create individualized treatment plans and protocols, thus guiding
personalized cancer therapy. Utilizing these unique diagnostic tools
and the Eight Treatment Methods as presented above may further
enhance clinical outcomes.
As researchers discover the mechanisms and effects of
Chinese medicinal herbs on specific body systems such as T
cells (summarized in Table 1), we can form consensus
treatments and offer more valuable insights into cancer patient
care. Looking forward, future investigations should be directed at
TCM’s effects on cancer stem cells and the tumor
microenvironment (Qi et al., 2015; Xiang et al., 2019), as these
represent exciting potential for the discovery of new multi-
targeted cancer drugs and therapies.
