Abstract: A highly efficient and milder protocol for the syntheses of novel series of 2-aminothiazoles
bearing 5-methylisoxazoline and pyridine-piperazine hybrid molecules has been developed. The target
compounds 13a-e were screened for their in vitro cytotoxicity activity against various tumor cell lines
including MCF-7 (human breast adenocarcinoma), HCT-116 (colorectal carcinoma), Jurkat (human Tcell
leukemia) and THP-1 (human acute monocytic leukemia). The bioactive assay showed most of the
new compounds exhibited promising results in comparison with the parental Sunitinib. The synthesized
compounds could well be used in the future as lead anticancer drugs in drug development studies. The
synthesized compounds were fully characterized by IR, 1H NMR, 13C NMR, elemental analysis and
mass spectral data.

Abstract Objective: To explore the mechanism of action of Radix et Rhizoma Rhei (Dahuang) (RERR) and Semen Persicae (Taoren) (SP) on adhesive intestinal obstruction (AIO). Methods: The main targets of the active ingredients of RERR and SP were filtered based on the traditional Chinese medicine system pharmacology analysis platform. Cytoscape 3.2.1 was applied to build the ingredient-target network of RERR and SP for AIO. Results: Fifteen active components were predicted from the RERR and SP herb pair, such as aloe-emodin, catechin, rhein, gibberellin (GA) 119, GA120 and GA121. These components were applied to 59 targets mainly involved in many biological processes such as signal transduction, anti-apoptosis, and inflammatory response involved in activating the immune effect. Conclusion: This study proposes the system pharmacology method and identifies the potent combination therapeutic mechanism of RERR and SP for AIO. This strategy will provide a new insight to the study of herb combinations.

This work demonstrates that intracellular distribution is not ruled only by physical-chemical parameters, rather it is mainly regulated by specific biological-mediated mechanisms. Substances with
apparent chemical similarity may show different distribution profile, as shown by the intra-nuclear distribution of polyphenols. While our results derive from a limited number of substances applied to
one cell line, it is plausible that using different substances and/or different cell lines would also have shown that intracellular distribution is not directly related to physical-chemical parameters.
Chemical uptake should be specifically measured and simple extrapolations based on physical-chemical properties may provide misleading decision
Recent innovations of ultrasound green technology in herbal phytochemistry: A...Mostafa Gouda
Ultrasound (US) has become one of the most important techniques in green chemistry and emerging technologies.
Many research investigations documented the usefulness of US in a wide range of applications in food
science, nanotechnology, and complementary medicine, where effective extraction of natural products is
important. However, as with all novel technologies, US has advantages and limitations that require clarification
for full adaptation at an industrial scale. The present review discusses recent applications of US in herbal
phytochemistry with the emphasis on US effects on chemical structures of bioactive compounds extracted from
herbs and their bioactivities. The impact of different US processing conditions such as frequency, intensity,
duration, temperature, and pressure on the effectiveness of the extraction process and the properties of the
extracted materials are also discussed. Different frequencies and intensities of US have demonstrated its potential
applications in modifying, determining, and predicting the physicochemical properties of herbs and their extracts.
US has important applications in nanotechnology where it supports the fabrication of inexpensive and ecofriendly
herbal nanostructures, as well as acoustic-based biosensors for chemical imaging of the herbal tissues.
The application of US enhances the rates of chemical processes such as hydrolysis of herbal fibers, which reduces
the time and energy consumed without affecting the quality of the final products. Overall, the use of US in herbal
science has great potential to create novel chemical constructions and to be used as an innovative diagnostic
system in various biomedical, food, and analytical applications.

The molecular properties of compounds expressing growth inhibition of Mycobacterium tuberculosis are determined and examined for underlying relationships by pattern recognition methods. Pattern recognition methods such as hierarchical cluster analysis will show relationships between compounds. Descriptive statistical analysis of molecular properties reveal commonality among bacteriostatic compounds. Outliers within any category of descriptor is identified by Grubb’s test. Potency of growth inhibition measured as MIC (minimum inhibitory concentration) after in vitro evaluation will be compared and analyzed. Structure moieties and their effect on activity is identified. All compounds analyzed showed substantial growth inhibition of Mycobacterium tuberculosis, having MIC values ranging from 16.7 µgrams/milliliter to 65.9 µgrams/milliliter (isoniazid MIC at 14.7 µgrams/milliliter). Ranges in values of Log P, number of atoms, and molecular weight were, respectively: -1.89 to 1.10, 11 to 25 (isoniazid at 10), and 150.18 grams/mole to 345.38 grams/mole (isoniazid at 137.14). All eight compounds and isoniazid showed favorable bioactivity within six categories of measureable bioactivity scores. The molecular properties of eight compounds and isoniazid varied, however, remained favorable in drug-likeness with zero violations of the Rule of 5. Interrelationships of the descriptors were revealed by statistical analysi

Studies have demonstrated genotoxic effects by the presence of micronucleus in exfoliated cells from the buccal mucosa of agricultural workers exposed to pesticides. This study has assessed the genotoxic effects of pesticides on 61 agricultural workers from the state of Piauí, Brazil. 31 individuals were exposed to pesticides and 30 are from the same area, but were not involved in pesticides application. Cytogenetic damage were evaluated through micronucleus test in cells from the buccal mucosa and some parameters such as hematological and levels of enzymes. Exposed individuals exhibited cytogenetic damage with increased number of micronuclei in cells from the buccal mucosa in comparison with subjects from the control group with significant statistical difference (P < 0.01). We perceive that there is a statistically no significant (P > 0.05) increase in levels of plasmatic and eritrocytaireacetylcholinesterase and no statistically significant increase of phosphatase alkaline were detected in exposed workers in relation to the control group. No association was found in relation to smoking habits, alcohol consumption, protection utensils and the biomarkers analyzed or the biochemical analysis. Analysis of variance revealed a correlation between occupational exposure to pesticides of workers in Piauí and the presence of micronuclei (P < 0.05).

Annual advances of integrative pharmacology in 2019LucyPi1
Abstract Representative studies concerning the pharmacology of traditional medicine and active herbal products have been summarized over the past 12 months. This annual integrative pharmacology review encompasses research articles published during 2019 on the bioactive compounds and extracts used in traditional medicine. Reports highlighting the pharmacology progress of traditional medicine were specifically introduced, including artemisinin for cancer cell sensibility and induction to ferroptosis, rutin for neuroinflammation suppression, Ginseng Radix et Rhizoma for gut microbiota regulation against obesity, green tea and Pu-erh tea for metabolic syndrome, and marine-derived oligosaccharide (GV-971) from brown algae for anti-dementia. Moreover, novel TCM molecular targets and pharmacological mechanisms were trialed against different human diseases, including cancers, cardiovascular, cerebrovascular diseases, diabetes, and metabolic diseases. Notably, herb-derived bioactive products have become important treatment alternatives for cancer research in 2019. Cardiovascular and cerebrovascular diseases, together with diabetes and metabolic diseases, are ongoing research areas for traditional medicine. Moreover, inflammation and infectious disease are also attracting more attention by researchers, which might have been influenced by seasonal influenza or HIV/Ebola viral infections. Further traditional medicine investigations are required in neurodegenerative diseases, depression, and mental diseases. Taken together, the findings of the integrative pharmacology review in 2019 provide a vast number of novel lead compounds or drug candidates for future clinical agent development and also details a novel series of attractive therapeutic targets and molecular mechanisms for human diseases.

Cancer Chemoprevention by Flavonoids, Dietary Polyphenols and Terpenoids Dr Varruchi Sharma
The world population is aging, and cancer is always considered to be one of the major causes of death all over the globe. The advent of recent drug-targeted therapies undoubtedly is going to reduce the incidence of cancer over the coming years. However, the frequency of occurrence of such chronic diseases like cancer would continue to increase. Therefore, the search for a safer and cost-effective treatment is urgently needed. Phytochemicals found in plants, foods, vegetables, tea, etc. have emerged as proven therapeutic compounds modulating signaling pathways involved in cancer. We carried out a structured search of bibliographic databases for peer-reviewed research literature using the keywords: cancer chemoprevention, flavonoids, dietary polyphenols, terpenoids, bioactive, microbiota. Quality of the retrieved papers and characteristic outcomes of the articles included in the study was assessed by employing standard tools and deductive qualitative content analysis methodology. The development of personalized supplements comprising particular phytochemicals has been the key, especially dealing with chronic inflammatory disorders like cancer. Better understanding at the molecular level explains the influence of phytochemicals on human health, which has been extensively covered through this review. Moreover, the wide collection of dietary polyphenols that has significant properties in reference to human health has been highlighted. Furthermore, the etiology of end products of such phytochemicals, especially on the modulation of gut microbiota and the host-microbial interactions thereof, need to be properly understood. The present study summarizes the chemoprevention and treatment of cancer using the bioactive components, including flavonoids, dietary polyphenols, and terpenoids. Likewise, the effect of dietary polyphenols on the human gut microbiota has been realized more recently. However, more research is needed in this field, especially focused on the communications, interlinks between the gut microbiota and polyphenols with the precise mechanism of action.

Antitumor applications of nano-traditional Chinese medicineLucyPi1
An article by Deng et al. [1] that was first published in ACS Nano in 2019 revealed that nanoparticles extracted from cuttlefish ink (CINPs) could inhibit tumor growth by synergizing immunotherapy and photothermal therapy. The researchers found that these CINPs, which had significant antitumor efficacy, could effectively reprogram tumor-associated macrophages (TAMs) from the immune-suppressive M2-like phenotype to the antitumor M1-like phenotype.
Cytotoxicity of Blended Versus Single Medicinal Mushroom Extracts on Human Ca...Jolene1981
ABSTRACT: The use of mushrooms contributes to human nutrition by providing low lipid content of lipids and high dietary fiber content, as well as significant content of other biologically active compounds such as polysaccharides, minerals, vitamins, and polyphenolic antioxidants. This study aimed to determine the content of polyphenols and polysaccharides, as well as the cytotoxic and antioxidative properties of several medicinal mushroom preparations. The content of total phenols and flavonoids of preparations of blended mushroom extracts (Lentifom, Super Polyporin, Agarikon, Agarikon Plus, Agarikon.1, and Mykoprotect.1) was evaluated quantitatively by using ultraviolet–visible spectroscopy spectrophotometric methods. The antioxidant capacity of the preparations was evaluated using the ABTS (2,2′-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) and ferric reducing/antioxidant power assays. The content of water-soluble polysaccharides was determined using a specific gravimetric method, based on ethanol precipitation. To determine cytotoxic effects of single and blended mushroom extracts, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) and neutral red assays were conducted using human small cell lung cancer, lung adenocarcinoma, colon cancer, and brain astrocytoma cancer cells. The obtained results suggest that due to the significant content of beneficial polyphenolic antioxidants and soluble polysaccharides, use of these mushroom preparations is beneficial in maintaining good health, as well as in the prevention and adjuvant biotherapy of various human pathological aberrations. These results reveal that these extracts exhibit different cytotoxic effects on tumor cells originating from different tissues. In addition, the comparison of investigated blended mushroom extracts with three well-known commercial mushroom products derived from single mushroom species or single mushroom compounds shows that blended mushroom extracts exhibit significantly stronger cytotoxic effects on human tumor cell lines.
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.

Antibacterial Effect of Endophytic Actinomycetes from Marine Algae against Multi Drug Resistant Gram Negative Bacteria by Manoharan N in Examines in Marine Biology & Oceanography
Chlorogenic acid may be a potent inhibitor of dimeric SARS-CoV-2 main proteas...LucyPi1
Abstract Background: Since the emergence of coronavirus disease 2019 to date, there is no available approved drug or definitive treatment for coronavirus disease 2019 viral infection, and the identification of novel hits against therapeutic targets has become a global emergency. Echinacea purpurea is a traditional herb utilized to treat cough, fever, sore throat, respiratory tract infection, and so on as an immune stimulant. In this study, in silico molecular docking approach was used to screen phytocompounds from E. purpurea against severe acute respiratory syndrome coronavirus 2 main protease 3C-like protease (3CLpro) and severe acute respiratory syndrome coronavirus main peptidase (96% sequence similarity) to blunt the viral gene expression and viral replication. Methods: Initially, we screened phytocompounds for their druggability and ADMET property. Furthermore, x-ray crystallographic structures of main proteases 3CLpro and main peptidase having Protein Data Bank ID 6LU7 and 2GTB were used as protein targets for the identification of potential drug candidates. We performed docking using AutoDock Vina by PyRx 0.8 software. BIOVIA Discovery Studio Visualizer v2019 was used to analyze ligand-protein complex. The probable protein targets of the selected compound were predicted by BindingDB (P ≥ 0.7). STRING and Kyoto Encyclopedia of Genes and Genomes pathways are utilized to identify the molecular pathways modulated by the predicted targets (FDR ≤ 0.05), and the network interaction between compounds and protein pathways was constricted by Cytoscape 3.6.1. Results: Among all the compounds, chlorogenic acid showed druggable characteristics and scored the lowest binding energy with main protease and main peptidase via interacting with active site 1 domain amino acid residues. Interestingly, chlorogenic acid interacted with Phe140 main protease 3CLpro, which is potentially involved in the dimerization. Enrichment analysis identified chlorogenic acid to modulate insulin resistance, necroptosis, interleukin-17, tumor necrosis factor signaling pathway, legionellosis, T helper 17 cell differentiation, advanced glycation end products and receptor for advanced glycation end products, mitogen-activated protein kinase, Ras, estrogen, vascular endothelial growth factor, B-cell receptor, nuclear factor kappa B, Rap1, hypoxia inducible factor-1, phosphatidylinositide 3-kinase-Akt, insulin, mechanistic target of rapamycin, p53, retinoic acid inducible gene I like receptor, and ErbB signaling pathways. Conclusion: Chlorogenic acid may act as a potent main protease 3CLpro inhibitor and may also inhibit the severe acute respiratory syndrome coronavirus 2 dimerization, viral gene expression, and replication within the lung epithelium. Chlorogenic acid may go a long way in finding one of the multipronged solutions to tackle coronavirus disease 2019 viral infection in the future.

Reliability and validity of the Tibetan medicine constitution scale: a cross-...LucyPi1
Abstract Background: The constitutional theory is an important aspect of Tibetan medicine, however a quantitative measurement tool for constitution identification still does not exist. The objective of this study is to evaluate the reliability and validity of a Tibetan medicine constitution scale (TMCS) that consists of three sub-scales and 31 items. Methods: From June to July 2019, 622 people from the general population in Beijing, China, aged 18 to 60 were investigated. We employed Cronbach’s alpha (α), split-half reliability, and test-retest reliability to determine the reliability of the scale. The content validity and contract validity of the TMCS were evaluated using factor analysis and correlation analysis based on Tibetan medicine theory. The items were screened according to the reliability test results. Results: After the items were screened, 22 items remained in the scale. The Cronbach’s alpha value for the internal consistency reliability of the TMCS was 0.754 (95% confidence interval (CI): 0.700–0.761). The correlation coefficient for the two-week test-retest of the total score was 0.726 (95% CI: 0.571–0.834). The split-half coefficient was 0.689 (95% CI: 0.640–0.734). The scale can be explained by eight potential factors, including morphological structure, physiological function, personality, adaptability, etc. The body mass index was negatively correlated with the score of the sub-rlung scale (r = − 0.376), slightly positively correlated with the sub-mkhris pa scale (r = 0.099), and positively correlated with the sub-bad kan scale (r = 0.362). Conclusion: The TMCS is a reliable and valid instrument that can be used to assess the body constitution of the general population in Beijing, China. Future studies are needed to explore the differences in biological characteristics among the constitutional types and the association between constitution and disease.
The riddles of number nine in Chinese medicine processing methodLucyPi1
Abstract The “nine cycles of steaming and shining”, “nine making”, “nine turns” and “nine cycles of calcining and quenching” methods that are recorded and used since ancient times are merely one aspect of the unique processing methods of traditional Chinese medicine. Inducing the Chinese medicine processing method “nine cycles of steaming and shining” from historical review and summarizing the practical wisdom based on the canonical aspects of traditional Chinese medicine and the experiences of ancient Chinese medicine sages to promote the new development of traditional Chinese medicine. After the long-term and multiple “nine” processing, the materials of traditional Chinese medicine exhibit significant beneficial changes in terms of taste, efficacy, and chemical composition contents, thus emphasizing that Chinese medicine processing plays a significant role in their efficacy enhancement and toxicity reduction. Heshouwu (Polygoni Multiflori Radix), Dihuang (Rehmanniae Radix), Huangjing (Rhizoma Polygonati), Dahuang (Radix et Rhizoma Rhei), and Xixiancao (Herba Siegesbeckiae) are representatives of Chinese medicinal materials prepared using the “nine-system” processing method. This review discovers the aim and the molecular mechanism of “nine” processing of the abovementioned herbs from the viewpoints of modern pharmacochemistry and pharmacology to provide a theoretical support for the “nine” processing method of traditional Chinese medicine and to promote the international market of traditional Chinese medicine.
Research progress in the use of leeches for medical purposesLucyPi1
Abstract Leeches are invertebrates that have a long history of application in the development of human medicine in both the East and the West. This paper comprehensively analyzes and evaluates current research and the latest progress with regard to the application of leeches, their medical value, and their application prospects from various perspectives, so as to provide a reference for new viewpoints and directions for research on leeches. Modern research has revealed that leeches contain various bioactive components, which have pharmacological effects such as anticoagulation, antithrombosis, blood viscosity reduction, and anti-atherosclerosis. Leech therapy is an important treatment approach for venous congestion after microsurgery and is also an effective adjuvant treatment for diabetic feet, chronic pain, and tumors. Therefore, leeches are of importance for the research and development of new drugs, the restoration of blood supply after surgery, and the adjuvant treatment of diseases accompanied by blood blocking. In addition, leeches can also be used as model organisms for research in evolutionary biology and invertebrate neurophysiology as well as in neurophysiological, behavioral, and functional studies.
Brucea javanica oil inhibits proliferation of hepatocellular carcinoma cells ...LucyPi1
Abstract Background: Brucea javanica oil (BJO), distributed primarily in Southeast Asia, has long been utilized as a therapeutic agent for treating malignancies. However, its anticancer mechanisms are not clearly understood. The objective of this study was to examine the mechanisms underlying its treatment of hepatocellular carcinoma cells. Methods: CCK8 assay was used to evaluate cell viability. Hoechst33342 staining and flow cytometry analyses were used to examine apoptosis. Mito-Tracker Red CMXRos kit was used to measure the membrane potential of mitochondria. ATP assay kit was used to evaluate ATP levels. Western blots were used to assess the presence of AKT, adenosine monophosphate-activated protein kinase, Caspase3, Caspase9, Bax, and Bcl-2. Results: BJO inhibited the proliferation of hepatocellular carcinoma cells HepG2 in a time- and dose-dependent manner. It induced apoptosis, with the percentage of cells treated with 50–150 μg/mL BJO increasing from 8.01% to 28.02% in a concentration-dependent manner (P < 0.05, when 50 μg/mL of BJO group compared with the control group; P < 0.001, when 100 or 150 μg/mL of BJO group compared with the control group). After exposed to BJO, the expression of C-caspase3, C-caspase9 and Bax upregulated while that of Bcl-2 downregulated. BJO suppressed the PI3K/AKT pathway and promoted phosphorylation of adenosine monophosphate-activated protein kinase, while repressing the phosphorylation of mechanistic target of rapamycin. Compared with treatment by BJO alone, the PI3K/AKT agonist 740Y-P increased the survival rate of HepG2 cells (P < 0.01) and attenuated the inhibitory effect of BJO on cell apoptosis (P < 0.05). Conclusion: BJO is capable of inhibiting proliferation of HepG2 cells and inducing apoptosis via the PI3K/AKT pathway.

Abstract Background: Our previous study shows that the empirical formula of Chinese medicine Jianpi-yangwei decoction (JYD) can improve the quality of life in patients with gastric cancer undergoing chemotherapy by increasing beneficial gut bacteria and decreasing harmful bacteria. The present study aims to investigate the effect of JYD on gut fungi in patients with gastric cancer undergoing chemotherapy. Methods: A total of 73 patients with gastric cancer undergoing chemotherapy were recruited. Twenty-nine patients in the chemotherapy group were given standard chemotherapy and 44 patients in the observation group were given JYD plus standard chemotherapy. A control group (55 cases) was recruited from the healthy medical examiners. After 3 months of treatment, life-quality score was evaluated and fecal microbiota was tested by high-throughput sequencing based on the 18S rRNA gene. Results: After treatment, life-quality score in the observation group was significantly lower than that in the chemotherapy group (P < 0.05). There was no significant difference between the observation and control groups’ diversity and richness indices of intestinal fungi. The Chao index for intestinal fungi in the chemotherapy group was significantly lower than that in the observation group (P < 0.05). There was a significant difference between the control and chemotherapy groups in the intestinal fungi according to Shannon and Simpson indices (P < 0.05). Linear discriminant analysis effect size analysis showed no significant differences among the three groups, but significant difference in intestinal fungi was observed between the observation group and the chemotherapy group. At the genus level, the relative abundance of the Aspergillus genus in the observation and control groups was significantly lower (P < 0.05), the relative abundance of the Cutaneotrichosporon, Galactomyces, and Ganoderma genus taxa was significantly higher compared with those in the chemotherapy group (P < 0.05), and there was no significant difference between the observation group and control group. Conclusion: JYD can ameliorate chemotherapy-induced fungal dysbacteriosis in patients with gastric cancer undergoing chemotherapy and improve the quality of life of patients.
A broad perspective on COVID-19: a global pandemic and a focus on preventive ...LucyPi1
Abstract Coronavirus 2019 has become a highly infectious disease caused by severe acute respiratory syndrome coronavirus-2, a strain of novel coronavirus, which challenges millions of global healthcare facilities. Coronavirus are sub-microscopic, single stranded positive sense RNA viruses that leads to multi organ dysfunction syndrome, severe acute and chronic respiratory distress syndrome and pneumonia. The spike glycoprotein structure of the virus causes the viral protein to bind with the receptors on the lung and gut through angiotensin-converting enzyme 2. In some cases, the infected patients become hyper to the immune system because of the uncontrolled production of cytokines resulting in “cytokine storm”, a devastating consequence of coronavirus disease 2019. Due to the rapid mutant strain and infective nature of severe acute respiratory syndrome coronavirus-2, discovering a drug or developing a vaccine remains a global challenge. However, some anti-viral agents, certain protease inhibitor drugs, non-steroidal inflammatory drugs and convalescent plasma treatment were suggested. The containment and social distancing measures only aim at reducing the rate of new infections. In this view, we suggest certain traditional herbs and complementary and alternative medicine as a supporting public healthcare measure to boost the immune system and also may provide some lead to treat and prevent this infection.
The coastal medicinal plant Vitex rotundifolia: a mini-review on its bioactiv...LucyPi1
Abstract Humans have long used natural remedies like plants and herbs to treat disease. Furthermore, research has been ongoing to find alternative pharmaceutical drugs based on traditionally used plants, as natural products show fewer side effects compared to synthetic drugs. Medicinal plants have long been targeted in drug development due to their bioactive compounds like alkaloids, flavonoids, and terpenoids. This is not only the case for terrestrial plants, but marine environments also provide a larger diversity of flora and fauna with medicinal bioactive compounds. Vitex rotundifolia, also known as Beach Vitex, is a coastal plant that has been traditionally used to treat a variety of diseases including premenstrual syndrome, headaches, migraines, colds, and eye pain. There have been many review papers on V. rotundifolia, emphasizing its taxonomy, distribution, and biological activity. Our current mini-review not only summarizes the pharmacology and bioactivity of V. rotundifolia, but it also provides new information on the main bioactive compounds of V. rotundifolia such as flavonoids, phenolic acid, and terpenes and their current pharmacological activity in vitro and in vivo research. This information can be useful for developing new pharmaceutical and nutraceutical agents to treat and manage disease.
International expert consensus on clinical application of traditional Chinese...LucyPi1
Abstract Guided by the theory of traditional Chinese medicine (TCM), TCM formula granules are made through the optimal process of extraction, concentration, drying, and granulation by combining modern new preparation technologies and pharmaceutical technologies. TCM formula granules are stable, safe, convenient, and effective. Compared with TCM decoction pieces, TCM formula granules can achieve the full process control of its industry chain from field to workshop and standardize the management of the origin of medicinal materials, processing of decoction pieces, processing technology, quality inspection, sales, and products distribution. TCM formula granules can partially replace Chinese patent medicines. Only available for around 800 common varieties of TCM, TCM formula granules cannot replace decoction pieces for many types which are not commonly used in clinical practice. A large number of formula granules are used in clinical and animal studies so that investigators no longer need to extract and control the quality of TCM decoction pieces. How to improve the production process, establish the quality standard, perfect the regulatory system, and expand the clinical application are the problems we need to solve as soon as possible for the better development of formula granules.
Bibliometric analysis of acupuncture research through the Web of Science data...LucyPi1
Abstract Background: The main points of focus of bibliometric analysis of acupuncture treatment of diseases include pain (headache, low back pain), insomnia, and knee osteoarthritis, for example. In this paper, we analyze the frontiers, hotspots, and research trends of acupuncture over the past 30 years and compare them for each of three 10-year periods. Methods: All the studies on acupuncture research in three different periods (1990–1999, 2000–2009, 2010–2019) were collected from the Web of Science database. The evolution of the research, hotspots, and trends in acupuncture were explored intuitively by analyzing the frequency, betweenness centrality, and subject word clustering of the three periods. Results: (1) 1990–1999, the main content relating to research was the mechanism of research of acupuncture treatment of pain. Naloxone was the high-frequency subject word, and centrality included, for example, the spinal cord, enkephalin, smoking cessation, and detoxification. The results of keyword cluster analysis showed that the main research content included capsaicin-induced neurogenic edema, chemical dependency treatment, afferent fiber, and sufferers from xerostomia. (2) 2000–2009, during this stage, the frequency of keywords appeared in new research content such as randomized controlled trials of acupuncture and low back pain, but pain still dominated the main research content. From the perspective of intermediary centrality, along with the rise in randomized controlled trials, there were many important meta-analyses, as well as the management of acupuncture treatment. The main elements of the keyword cluster analysis included, for example, systematic review, randomized controlled pilot study, add-on therapy, brief overview, and ovarian morphology. (3) 2010–2019, during this period, compared with the previous two stages, there was increased frequency of keywords, a growth in clinical randomized controlled trials, and distribution of centrality was evident in the emergence of acupuncture in care, osteoarthritis treatment, and breast cancer research. The keyword clustering covered, for example, neural specificity, inflammatory reaction, chronic pain, sleep pattern, and consort statement. Conclusion: This article summarizes the trend of development of acupuncture from 1990 to 2019 and compares the main research categories and hotspots in each of three different 10-year periods within this span, thereby helping elucidate the research direction within the field.
The dynamic changes and mechanisms of Rehmanniae radix processing based on Ma...LucyPi1
Abstract Background: Traditional Chinese medicines are usually processed before they are used for clinical treatment. This is done in a way associated with the Maillard reaction. Methods: Based on the Maillard reaction, this paper analyzed the degree of processing of rehmannia root (Rehmanniae radix) relative to the dynamic variation rules of Maillard reaction index parameters, including pH, A420, amino acids, and 5-hydroxymethylfurfural. Furthermore, this study introduced thermal analysis techniques and pyrolysis kinetics to assess the influence of the correlation between processing raw rehmannia root and the Maillard reaction during carbonization. It then went through the whole process of transforming the raw material to end-product in order to explain the scientific connotation of processing it. Results: The results showed that each time rehmannia root was processed, its pH value and amino acid content decreased, while the A420 value and 5-HMF increased. Processing with wine shows a significant difference in these experimental indexes. The position and intensity of the maximum thermal weight loss rate peak of processed rehmannia root at different degrees of processing are different. Comprehensive quantitative 221 ± 0.2 °C for processed rehmannia root carbonization was the processing temperature limit. Moreover, the kinetic solution verified that the activation energy corresponding to the carbonization temperature was close to the maximum value of the activation energy of the whole carbonization process, and the optimal mechanism function was g(α) = ((1 − α) − 1/3 − 1)2. Conclusion: The Maillard reaction occurred during the processing of rehmannia root mixed with carbonization. With each increase of the number of steaming and drying cycles involved in the processing, the level of Maillard reaction increased significantly. The wine-steaming method had a significant effect on the quality of the processed product.

Abstract Background: Vine tea from fermented Ampelopsis grossedentata leaves has been used as a herbal tea and folk medicine in the southern region of China for hundreds of years. The aim of this investigation was to analyze the total flavonoids found in vine tea, including three bioactive flavonoids, and the total phenolic contents in the aqueous methanol extracts of 10 vine tea samples. In addition, this study also aimed to examine the antioxidant activity of dihydromyricetin and vine tea’s flavonoid-rich extract. Methods: The total flavonoids and total phenolic content assay of extracts from vine tea were performed by ultraviolet-visible spectroscopy and epoch microplate spectrophotometer, respectively. Three bioactive flavonoids were quantified simultaneously using high performance liquid chromatography. The antioxidant activity of dihydromyricetin and vine tea’s flavonoid-rich extract was evaluated in vitro using six different methods. Results: Vine tea contained a large number of flavonoids, with dihydromyricetin as its main constituent. The flavonoid-rich extract exhibited a significant scavenging effect on superoxide anion radicals, and on 3-ethylbenzthiazoline-6-sulphonic acid and 1,1-diphenyl-2-picrylhydrazyl radicals. It also possessed definite activity in lipid peroxidation inhibition, ferric reduction, and the moderation of Fe2+ ion chelation ability. There was a significant negative correlation between dihydromyricetin content and antioxidant activity in the vine tea samples, including superoxide anion radical scavenging activity (P = −0.754, P < 0.05), lipid peroxidation inhibition activity (P = −0.759, P < 0.05), ferric-reducing antioxidant power (P = −0.843, P < 0.01), respectively. Dihydromyricetin played a dominant role in the antioxidant activities of the flavonoid-rich extract. Conclusion: Vine tea’s flavonoid-rich extract could be used as a new antioxidant source to safeguard against oxidative stress.
Advances in anti-inflammatory and immunoregulatory mechanisms of sinomenineLucyPi1
Abstract Sinomenine, a major active ingredient from traditional Chinese medicine Qingfengteng (Sinomenium acutum (Thunb.) Rehd.et Wils.), has been proven to have anti-inflammatory, analgesic, anti-tumor, immunomodulatory and other pharmacological effects, and is clinically used for various inflammatory and autoimmune diseases. However, due to complex molecular mechanisms and pathological characteristics in inflammatory and immune responses, the precise anti-inflammatory and immunological mechanisms of sinomenine are still unclear. This review summarizes the anti-inflammatory and immunoregulatory mechanisms of sinomenine during recent years in rheumatoid arthritis, respiratory system, nervous system, digestive system and organ transplant rejection. The molecular pharmacological mechanisms of sinomenine responsible for anti-inflammatory and immunosuppressive effects were in detail introduced based on 3 aspects including cytokines induction, signal pathways modulation and immune cells function regulation. Moreover, this review also raises some concerns and challenges in future sinomenine study, which will contribute to crucial theoretical and practical significance for in-depth development and utilization of sinomenine as medicinal resource.
Abstract Background: Non-alcoholic fatty liver disease (NAFLD) can cause insulin resistance (IR) and diabetes. Our previous studies have demonstrated that Jian-Gan-Xiao-Zhi decoction (JGXZ) could be effective for the treatment of NAFLD and IR. However, the possible mechanism underlying the effects of JGXZ on NAFLD and IR remains unknown. Methods: Fifty rats received a high-fat high-carbohydrate (HFHC) diet for 12 weeks to induce NAFLD. After 4 weeks of HFHC treatment, rats were orally treated with JGXZ (8, 16, and 32 g/kg weight) for 8 weeks. Ten rats in the control group received standard chow. In the positive control group, rats were orally treated with metformin (90 mg/kg weight) for 8 weeks. After JGXZ and metformin treatment, H&E staining was conducted on rat livers and serum biochemical markers, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), and total cholesterol (TC), were measured using test kits. Moreover, a fasting blood glucose test and an oral glucose tolerance test (OGTT) were conducted. Serum levels of insulin were determined using ELISA kit, and the homeostatic model assessment of insulin resistance (HOMA-IR) was calculated. The levels of total insulin receptor substrate-1 (IRS1), AMP-activated protein kinase-α (AMPKα) and c-Jun N-terminal kinase (JNK) as well as the levels of phosphorylation of IRS1 (p-IRS1), phosphorylation of AMPK (p-AMPK) and phosphorylation of JNK (p-JNK) were measured using western blotting. Results: The body weights in JGXZ low-, middle-, and high-dose groups were lower than those in the model group (P < 0.05, P < 0.01, P < 0.01, respectively). The serum levels of AST (P < 0.05 in JGXZ middle- and high-dose groups), ALT (P < 0.01 in JGXZ middle-dose group and P < 0.05 in JGXZ high-dose group), TG (P < 0.01 in JGXZ middle- and high-dose groups), and TC (P < 0.01) upon JGXZ treatment were lower those than in NAFLD model rats. H&E staining showed that JGXZ treatment reduced steatosis of the hepatocytes in NAFLD model rats. JGXZ decreased the levels of fasting blood glucose (P < 0.01), HOMA-IR (P < 0.01), AUC (area under the curve) of the OGTT (P < 0.05) and p-IRS1 (P < 0.01 in JGXZ middle- and high-dose groups, P < 0.05 in JGXZ low-dose groups). Moreover, JGXZ regulated the hepatic AMPKα/JNK pathway in NAFLD model rats, which reflected the induction of p-AMPKα and inhibition of p-JNK. Conclusion: This study showed that JGXZ improved liver function and reduced steatosis of the hepatocytes in NAFLD model rats. Moreover, JGXZ improved IR in NAFLD model rats. The possible mechanism underlying the effects of JGXZ on NAFLD and IR involves the modulation of the AMPK/JNK pathway.
Omics technology: an important tool in mechanism studies of Chinese herbal fo...LucyPi1
Identifying the active ingredients from natural herbal medicines and demonstrating their potential mechanisms are key points in the traditional Chinese medicine (TCM) field. In recent years, increasing studies have focused on the effects and mechanisms of Chinese herbal formulas. Basic studies on these formulas further coincide with the theory and practical use of TCM according to the clinical experiences for thousands of years. Single compounds have specific molecular structures; therefore, their methodologies in effect and mechanism studies are similar in both Western and Eastern medicines, making them more acceptable by researchers worldwide. On the contrary, the multicomponent, multitarget, and multipathway structures of Chinese formulas make it challenging to explore their mechanisms accurately where the routine method used in Western medicine studies would be inapplicable, which is the main reason for the unacceptance of Chinese herbal formulas by researchers worldwide and presents a huge obstacle to the modernization of TCM. With the rapid progress in basic TCM studies, scientific and technological innovations have achieved a breakthrough in TCM. Omic technology, a series of research methods based on high-throughput analysis and detection techniques in modern biological research system such as genomics, transcriptomics, proteomics, and metabolomics, evaluates thousands of targets and pathways rather than focusing on a single target or pathway and could screen the global changes in genes, proteins, metabolites, and other factors involved in the process of biological signaling transduction [1]. This is in agreement with the “holism” theory in TCM, which explains the overall mechanisms of Chinese herbal formulas comprehensively. In this study, we introduced the conventionally used omic technologies and their applications in research of mechanism studies of Chinese herbal formulas.
Gastrointestinal effects of Artemisia absinthium Linn. based on traditional P...LucyPi1
Abstract One of the most extensively used herbs in traditional Persian medicine (TPM) used in the treatment of gastrointestinal (GI) disorders, is the plant Artemisia absinthium Linn. (AAL). It also has a wide range of activities such as analgesic and anti-inflammatory, anti-oxidant, anti-fungal, and anti-bacterial activities, hepatoprotective, and neuroprotective activities in addition to having gastroprotective effects. This article is a review comparing TPM resources with new medicines. This review investigates this herb in major TPM sources and strives to extrapolate the exact function it serves in the digestive tract and compares the collected information on the function of AAL with information found in new medical resource databases such as ISI, Pubmed, Scopus, Google Scholar, and Scientific Information Database. AAL from the Asteraceae family of TPM, known as Afsentin, was used in the treatment of GI weaknesses, stomach pains, swellings, intestinal parasites, diarrhea, and vomiting. AAL increased appetite, so it was used for insect repellents and insecticide. Recent studies have indicated that the effects of this plant improved the symptoms of Crohn's disease and played a role in reducing inflammatory factors. It also has strong anti-parasitic, anti-insect, hepatoprotective, and antioxidant effects. Given the widespread use of AAL as a traditional medicine currently in use in different countries, particularly in the treatment of GI diseases, further clinical studies that focus on the therapeutic qualities of this plant are required in the future.
Jadwar (Delphinium denudatum Wall.): a medicinal plantLucyPi1
Abstract Delphinium denudatum Wall. is one of the important medicinal herbs of traditional Persian medicine and is known as Jadwar. Medicinal plants are the most widely used drugs in traditional Persian medicine and has been used for various diseases since earlier times. The medicinal uses of Delphinium denudatum Wall. date back to over 1,000 years ago. Rhazes (845–925 C.E.) was the first Persian physician and scientist who reported the use of Delphinium denudatum Wall. as a herbal remedy. During the following centuries, the usages of Delphinium denudatum Wall. in the treatment of various diseases has been mentioned in the books and references of traditional Persian medicine for cures to various diseases such as neurologic and psychiatric disease, gastrointestinal disease, fever, pain, and poisoning. According to modern studies, the dried roots of Delphinium denudatum Wall. have antipyretic, antimicrobial, anticonvulsant, hepatoprotective, antioxidant, and pain-relieving properties. Biomolecules from roots of Delphinium denudatum Wall. were also identified as potential cures for central nervous system diseases as well as for the amelioration of morphine addiction. Delphinium denudatum Wall., with its properties involving the prevention of mitochondrial dysfunction, reduction of oxidative stress, and inflammation and immune dysregulation, can be utilized in curing inflammatory disorders. The effective therapeutic influence of root extract of Delphinium denudatum Wall. against several diseases needs to be confirmed through controlled clinical trials. This article reviews the different features of Delphinium denudatum Wall. and focuses on the well-known therapeutic effects of this herbal drug on various human disorders and animal disease models.
Effects of chicory (Cichorium intybus L.) on nonalcoholic fatty liver diseaseLucyPi1
Abstract There is a dramatic increase in the prevalence of nonalcoholic fatty liver disease, which is slowly turning into a pandemic as well as a major challenge across the world. Nonalcoholic fatty liver disease is described as a range of liver conditions such as fat accumulation, hepatic steatosis, or end-stage liver disease. Patients with nonalcoholic fatty liver disease are asymptomatic and their mortality is higher than people without nonalcoholic fatty liver disease. The pathogenesis of nonalcoholic fatty liver disease has not been clearly determined yet. The “two hits” hypothesis is designed to explain the pathogenesis of nonalcoholic fatty liver disease. Dyslipidemia, oxidative stress, insulin resistance, obesity, and chronic inflammation are some of the morbidities involved in the progression of nonalcoholic fatty liver disease. Chicory (Cichorium intybus L.) is an herbaceous perennial, known as chicory. Chicory contains various compounds, such as vitamins, sonchuside A, caffeic acid derivatives, fructo-oligosaccharides, chlorogenic acid, magnolialide, polysaccharides, coumarins, phenolic acids, terpenoids, flavonoids, polyphenol, cichoriosides, ixerisosides, eudesmanolides, inulin, bitter sesquiterpene lactones, and alkaloids. Current research has revealed that chicory supplementation might be effective in the treatment of nonalcoholic fatty liver disease. The anti-inflammatory, antihepatotoxic, antihyperlipidemic, antidiabetic, antihyperglycemic, and antioxidant properties of chicory provide plausible mechanisms by which chicory may affect the various steps of disease progression and severity. Existing studies have shown that chicory supplementation has beneficial effects on nonalcoholic fatty liver disease, but the existence of only one human study and possible side effects of chicory necessitate further studies.
Effects of herbal medicine in gastroesophageal reflux disease symptoms: a sys...LucyPi1
Abstract Background: Pyrosis and regurgitation are the cardinal symptoms of gastroesophageal reflux disease. Several herbs have been used for treating gastrointestinal disorders worldwide. This systematic review was conducted to investigate the effects of medicinal herbs on gastroesophageal reflux disease and adverse events. Methods: MEDLINE (via PubMed; The United States National Library of Medicine, USA), Scopus, ScienceDirect, Cochrane Central Register of Controlled Trials, Web of Science, Magiran, and Scientific Information Database were systematically searched for human studies, without a time frame, using medical subject heading terms such as “gastroesophageal reflux disease”, “reflux”, “esophagitis” and “herbs”. Manual searches completed the electronic searches. Results: Thirteen randomized controlled trials were identified, including 1,164 participants from 1,509 publications. In comparing herbal medicine to placebo, there were no significant differences in terms of heartburn (P = 0.23 and 0.48), epigastric or abdominal pain (P = 0.35), reflux syndrome (P = 0.12), and effective rate (P = 0.60), but there was a significant difference in terms of acid regurgitation (P = 0.01). In comparing herbal medicine to drugs, there was a significant difference in terms of effective rate (P = 0.001), and there was one trial that reported a significant difference in terms of epigastric pain (P = 0.00001). Also, in comparing herbal medicine to drugs, there were no significant differences in terms of acid regurgitation (P = 0.39). Conclusion: This meta-analysis showed that herbal medicines are effective in treating gastroesophageal reflux disease. Further standardized researches with a large-scale, multicenter, and rigorous design are needed.
New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Background
Safety, effectiveness and quality control belong to
three basic characteristics of drug. During 2019, there
were a number of papers referred to the safety
assessment of toxins [1] like metal [2], elemental
distribution [3], toxic proteins [4, 5] and special
secondary metabolites in traditional medicine (TM),
which might be also the bioactivation of herbal
constituents [6]. The herbs included Cuscuta chinensis
Lam epithymum [7], Cassiae semen [8], Ephedra
sinica Stapf [9], MeLia toosendan Sieb.et Zucc. [10],
Psoralea corylifolia Linn. [11], Gynura segetum (Lour.)
Merr. [12], Leonurus artemisia (Laur.) S.Y. Hu F [13],
Polygonum multiflorum [14–16], Tripterygium
wilfordii Hook. f. [17, 18], Telfaria occidentalis root
[19, 20] and so forth. At the same time, people paid
attention to different age groups such as infants [2],
children [21–23], adults [24], pregnancy and the
postnatal period [13, 25–27] in the use of TM. Liquid
Chinese patent drug, especial for injection received
researchers’ more attention like Xiyanping injection
[28], Tianfoshen oral liquid [29], and motherwort
injection [13]. New detection technology like
multispectral optoacoustic tomography (MSOT)
imaging the precise location of
herbal-medicine-induced liver injury with 3D
information in a noninvasive way using
conjugated-polymer-based ratiometric nanoprobe was
applied [14]. A computational toxicology approach
was also applied to screening the hepatotoxic
ingredients in TM [15]. Furthermore, China played the
key role in the promotion of the rapid upsurge in this
field. Statistical analysis of annual publications of
toxicological studies on TM by relative percentages on
different countries is showed in Figure 1. USA ranked
the second important countries, while India was tied
with Canada and Brazil ranked the third place
researching the toxicology of TM. In addition,
compared to 2018, many counties like Australia,
Germany and UK started to pay attention to the safety
evaluation of TM.
Organ toxicity
Liver is regarded as the top 1 toxic target organ in
TM
Liver is the most important organ of drug metabolism
and detoxification in the body. For herb-induced liver
injury was a growing clinical and economic problem
worldwide, there were a large amount of researches
focusing on liver toxicity in 2019. For example, new
detection technologies like MSOT imaging the precise
location of Fallopia multiflora (Thunb.)
Harald-induced liver injury with 3D information was
applied due to oxidative/nitrosative stress resulted
from hepatically-generated reactive oxygen
species/reactive nitrogen species [14]. A computational
toxicology approach was applied to screening the
hepatotoxic ingredients in Fallopia multiflora (Thunb.)
Harald [15]. Integrating serum exosomal microRNA
and liver microRNA profiles were used to disclose the
mechanism of MeLia toosendan Sieb. et Zucc.-induced
hepatotoxicity in mice [10]. Meanwhile, metabolism
was used commonly to display cholestatic liver injury
caused by psoralen [30], isopsoralen [30] and Gynura
segetum (Lour.) [12], and metabolic disorder like
glycerophospholipid metabolism, primary bile acid
biosynthesis, sphingolipid metabolism, phenylalanine,
tyrosine and tryptophan biosynthesis, and tyrosine
metabolism by Daphne genkwa Sieb. et Zucc. [31],
Glycyrrhiza uralensis Fisch. [31], Sophora flavescens
Ait. [32] and Xysmalobium undulatum [33].
Kidney is considered as the second toxic target
organ in TM
Renal blood flow is abundant, accounting for 25% of
cardiac output, so a large number of drugs can reach
the kidney with blood flow to cause pathological
changes. For example, aristolochic acid I was
recognized as the major cause of aristolochic acid
nephropathy before [34]. During 2019, untargeted
liquid chromatograph-mass spectrometer-based
metabonomics was used to reveal that aristolochic acid
I inhibited amino acids metabolism, glucose
metabolism, beta-oxidation of fatty acids and the
tricarboxylic acid cycle in male mice [35]. Aristolochic
acid I could also react with genomic DNA to form
persistent DNA adducts with purines to induced
nephrotoxicity [36]. Chemotherapy usually induced
nephrotoxicity like cisplatin [37] and doxorubicin [38].
In the year of 2019, researchers reported that grape
pomace extract did not protect against
cisplatin-induced nephrotoxicity, but accentuated the
toxic effect of cisplatin [37]. Dioscorea bulbifera L.
delayed the excretion of doxorubicin and accumulated
doxorubicin in the body, which was associated with its
inhibition of P-glycoprotein in liver and kidneys [38].
Furthermore, it was reported that the incompatible herb
pair Euphorbia kansui T. N. Liou ex S. B. Ho and
Glycyrrhiza uralensis Fisch. induced hepatotoxicity
and nephrotoxicity and attenuated the effect of Gansui
Banxia decoction [39].
Other toxic target organs of TM
In 2019, a review introduced poisoning by toxic plants
in Hong Kong. 62 cases involving 26 poisonous plant
species were identified, among which Alocasia
macrorrhizos (Giant Alocasia), Gelsemium elegans
(Graceful Jessamine), and Rhododendron (Azalea)
species were the three most commonly encountered.
Gastrointestinal toxicity (n = 30, 48%), neurological
toxicity (n = 22, 35%), and hepatotoxicity (n = 6, 10%)
were the three most common clinical problems.
Forty-nine (79%) and eight (13%) patients had mild

and moderate toxicity, respectively. They were all
recovered shortly with supportive treatment. The
remaining five (8%) patients experienced severe
toxicity requiring intensive care support [40].
Meanwhile, the mechanisms of reproductive injuries
induced by combination of Daphne genkwa Sieb. et
Zucc. and Glycyrrhiza uralensis Fisch. [31],
cardiotoxicity and neurotoxicity caused by diester and
monoester diterpenoid alkaloids in processed Aconitum
carmichaeli Debx. root [41], cardiotoxicity induced by
Chloranthus serratus [42], gastrointestinal injury
incurred by Gardenia jasminoides Ellis [43] and so
forth were explained in 2019. These extracts should be
used with caution. Taken together, statistical analysis
of annual publication referred to different toxic target
organs induced by TM is summarized in Figure 2.
Current advances
Zebrafish embryoes are popular for evaluating the
safety of TM
Right now, the safety evaluation has been applied in
cellular, organ & individual levels. Rodents are
regarded as the common individual models to analyze
the safety of TM or natural products. Meanwhile,
zebrafish embryoes are secondly widely used because
of its rapid, medium throughput and cost-effective.
During 2019, it was used to evaluate the liver
protection and hepatotoxicity of saikosaponin a [44],
aloe emodin [45], and triptolide [46], teratogenicity of
Momordica charantia seeds and fruits [47], heart
toxicity of Libidibia ferrea (juca) [48], reproductive
toxicity of Endopleura uchi (Huber) Cuatrec [49] and
so forth. Although caenorhabditis elegans [50] and
drosophila [51] were popular in the safety evaluation
of various chemical compounds recently, there were no
relative research in TM in 2019.

Safety evaluation of TM in different kinds of people
Recently, safety medication has been concerned to
different kinds of people, such as infants [2], children
[21–23], adults [24] and maternal [13, 25–27]. During
2019, a review reported the safety of the herbal
medicinal product used during pregnancy and postnatal
period [25]. In this report, almond oil might induce
preterm birth, the use of oral raspberry leaf was related
to cesarean delivery; the application of heavy licorice
use was relative to early preterm birth by 3.07-fold.
African herbal medicine mwanaphepo was also
reported to be associated with maternal morbidity,
neonatal death or morbidity [25]. Meanwhile, other
research reported that Anastatica hierochuntica
aqueous extract [26] and Snus tobacco [27] displayed
potential toxicity during pregnancy. What’s more, it
attracted attention to the safety assessment of toxic
metals in commonly used pharmaceutical herbal
products in Jordanian market [2], a mixed extract
containing marshmallow root, chamomile flowers,
horsetail herb, walnut leaves, yarrow herb, oak bark
and dandelion herb in the treatment of acute
non-bacterial tonsillitis [21], and green tea [22] in
children.
New toxicology study technology
In 2019, new technology was used in toxicology
evaluation. For example, a computational toxicology
approach was also applied to screening the hepatotoxic
ingredients in TM [15]. Electrospray laser desorption
ionization mass spectrometry was used to rapid
identify herbal toxins [1]. MSOT imaging conjugated
with polymer-based ratiometric nanoprobe was applied
for the precise location of TM-induced liver injury
with 3D information in a noninvasive way [14].
Furthermore, integrating serum exosomal microRNA
and liver microRNA profiles were used to disclose the
mechanism of TM-induced hepatotoxicity in mice
[10].
Conclusion
Taken together, the annual research shows that liver,
kidney and heart are the mainly toxic target organs of
TM. Their toxic mechanisms include cell apoptosis,
metabolic disorder, oxidative stress, inflammatory
damage, liver and renal fibrosis and even inducing
carcinogenesis. Safety medication of TM has been
concerned to different kinds of people, such as infants,
children and maternal. Besides rodents, zebrafish
embryoes have been regarded as common models to
evaluate the safety of TM. New technologies in
toxicology focus on how to screen and identify toxin in
TM, how to image the precise location of TM-induced
tissue injury with 3D information, and how to explain
the mechanism of TM-induced toxicity. In the future,
study on the toxicity mechanism of other target organs,
drug safety in elders, new models and methods should
be used in the prevention of TM toxicology.
