Model informed precision medicine of Chinese herbal medicines formulas-A multi-scale mechanistic intelligent model

Recent trends suggest that Chinese herbal medicine formulas(CHM formulas)are promising treatments for complex diseases.To characterize the precise syndromes,precise diseases and precise targets of the precise targets between complex diseases and CHM formulas,we developed an artificial intelligence-based quantitative predictive algorithm(DeepTCM).DeepTCM has gone through multilevel model calibration and validation against a comprehensive set of herb and disease data so that it accurately captures the complex cellular signaling,molecular and theoretical levels of traditional Chinese medicine(TCM).As an example,our model simulated the optimal CHM formulas for the treatment of coronary heart disease(CHD)with depression,and through model sensitivity analysis,we calculated the balanced scoring of the formulas.Furthermore,we constructed a biological knowledge graph representing interactions by associating herb-target and gene-disease interactions.Finally,we experimentally confirmed the therapeutic effect and pharmacological mechanism of a novel model-predicted intervention in humans and mice.This novel multiscale model opened up a new avenue to combine“disease syndrome”and“macro micro”system modeling to facilitate translational research in CHM formulas.

The potential of Chinese herbal medicines in treating anxiety disorders

In recent years,there has not been much progress in developing anxiolytic drugs.Amongst the barriers are the lack of clarity on the pathogenesis of anxiety disorders,low product conversion rates for developing drugs targeting the receptors,and species variability.Some scientists have focused on natural medicines,especially herbal medicines in traditional Chinese medicine.New drugs with excellent anxiolytic activity are hoped to be found in herbal medicines with anxiolytic effects.This mini-review summarised three Chinese herbal medicines with anxiolytic effects and anxiolytic herbal formulas used in the traditional Chinese medicine clinic.Several key issues that block the development of new anxiolytic drugs are also discussed.We hope to provide some ideas for researching and developing new anxiolytic drugs and studying anxiolytic components in traditional Chinese medicine.

Developments in the study of Chinese herbal medicine's assessment index and action mechanism for diabetes mellitus

In traditional Chinese medicine(TCM),based on various pathogenic symptoms and the‘golden chamber’medical text,Huangdi Neijing,diabetes mellitus falls under the category‘collateral disease’.TCM,with its wealth of experience,has been treating diabetes for over two millennia.Different antidiabetic Chinese herbal medicines re-duce blood sugar,with their effective ingredients exerting unique advantages.As well as a glucose lowering effect,TCM also regulates bodily functions to prevent diabetes associated complications,with reduced side effects compared to western synthetic drugs.Chinese herbal medicine is usually composed of polysaccharides,saponins,al-kaloids,flavonoids,and terpenoids.These active ingredients reduce blood sugar via various mechanism of actions that include boosting endogenous insulin secretion,enhancing insulin sensitivity and adjusting key enzyme activity and scavenging free radicals.These actions regulate glycolipid metabolism in the body,eventually achiev-ing the goal of normalizing blood glucose.Using different animal models,a number of molecular markers are available for the detection of diabetes induction and the molecular pathology of the disease is becoming clearer.Nonetheless,there is a dearth of scientific data about the pharmacology,dose-effect relationship,and structure-activity relationship of TCM and its constituents.Further research into the efficacy,toxicity and mode of action of TCM,using different metabolic and molecular markers,is key to developing novel TCM antidiabetic formulations.

Unveiling the anticancer effect of traditional Chinese herbal medicine

In this issue of World Journal of Gastroenterology,Huang et al reported that Calculus bovis(CB),a traditional Chinese herbal medicine,impedes the growth of liver cancers in vivo.Through further in vitro studies,they showed that CB suppressed the M2 polarization of tumor-associated macrophages by suppressing the Wnt signaling pathway,which consequently inhibited the growth of liver cancer.Although the effects of traditional Chinese herbal medicine are often not scientifically proven,Huang et al successfully identified the molecular mechanism involved in the anticancer effect of CB,and it is anticipated that the molecular mechanisms involved in the effects of other traditional Chinese herbal medicines will be scientifically elucidated,as demonstrated in this article.

Chinese herbal medicine combined with Western medicine for Mycoplasma pneumoniae pneumonia in children:An overview of systematic reviews

Objective:To summarize the characteristics and evaluate the quality of the methodology and evidence within systematic reviews(SRs)of Chinese herbal medicine(CHM)for Mycoplasma pneumoniae pneumonia(MPP)inchildren.Methods:SRs of randomized controlled trials were searched using PubMed,the Cochrane Library,Embase,the Chinese National Knowledge Infrastructure Databases(CNKI),the Chinese Scientific Journals Database(VIP),Wanfang,and the SinoMed Database.SRs on the use of CHM alone or in combination with Western medications for MPP in children were included.The study compared the effects of Western medicine alone with those of CHM.The evidence quality using the A Measurement Tool to Assess Systematic Reviews(AMSTAR)2,the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)2020,and the Grading of Recommendations,Assessment,Development,and Evaluation(GRADE)criteria.The primary indicators were the total effective rate,fever subsidence time,and cough disappearance time.The secondary outcomes were pulmonary rale disappearance time,average hospitalization time,lung X-ray infiltrate disappearance time,immunological indices,and inflammatory cytokine levels.Results:Twelve relevant SRs were included;75%(9/12)were assessed as very low quality,and 25%(3/12)Were rated as low quality using the AMSTAR 2 criteria.According to the PRISMA 2020 checklist,the average SR score was 20.3 out of a 27 point maximum.In all SRs,CHM demonstrated improvement in symptoms and signs among children with MPP.The evidence quality using the GRADE criteria ranged from"very low"(>50%)to"moderate"(<5%).The most common downgrading factor was imprecision,followed by publication bias and inconsistency.Conclusion:This overview highlights the limited quality of the methodology and evidence of the included SRs.Although the included studies showed the beneficial effects of CHM on MPP in children,it was difficult to draw firm conclusions owing to methodological flaws.

Bioactive Components of Chinese Herbal Medicines in the Treatment of Glucose and Lipid Metabolism Disorders:Evidence and Potential Mechanisms

Disturbed cholesterol and glucose homeostasis play crucial roles in the development of various diseases such as cardiovascular diseases,cerebrovascular diseases,central nervous system diseases,and cancer.An increasing number of studies have shown that excessive body fat accumulation is associated with type 2 diabetes or insulin resistance in a vicious cycle.This vicious cycle promotes the occurrence and development of the aforementioned diseases.Therefore,stabilizing the blood lipids and blood glucose of patients is the predominant strategy for improving the symptoms of patients with cardiovascular,cerebrovascular,and central nervous system diseases.Traditional Chinese medicine,mainly Chinese herbal medicine(CHM),has a history of more than 2000 years in China,which has established a unique theory and accumulated a great wealth of clinical experience.Moreover,CHM has been widely used in China and other countries for the treatment of cardiovascular and cerebrovascular diseases,with the advantages of preventing and curing hyperlipidemia,diabetes,hypertension,and other diseases.However,the use of CHM in Western countries remains rather limited,partly because of the incomplete understanding of multiple complex components and uncertain pharmacological mechanisms.Herein,we review and discuss the benefits,molecular mechanisms,and clinical research progress of bioactive components of CHM and their preparations as therapeutics for hyperlipidemia and hyperglycemia.

Integration of Chinese herbal medicines and exercise for insomnia:a systematic review and meta-analysis

Background:As a disease,insomnia is often ignored by the general public.Insomnia,which not directly fatal,may be equivalent to chronic suicide if it is not paid attention to.However,there are many theories on how to treat insomnia,and researchers have been searching for a cure.Chinese herbal medicine(CHM)and exercise therapy(ET)are relatively effective,and have been used since ancient times to treat insomnia.This study aimed to examine the effect of CHM combined with ET(CHM-ET)on patients with insomnia.Methods:We searched eight electronic databases including PubMed,Web of Science,EMBASE,the Cochrane Library,the China National Knowledge Infrastructure(CNKI),the China Biology Medicine disc(CBMdisc),the China Science and Technology Journal Database(VIP),the Wanfang Database to find randomized controlled trials(RCTs)evaluating CHM-ET in the treatment of insomnia patients up to September 13,2022.Two researchers read and screened the publications to extract data.We used the pittsburgh sleep quality index(PSQI)as the evaluation indicators for each study,and the other was the total effective rate(TER).The Cochrane risk-of-bias assessment tool was used to assess the risk of bias of the included literature.The level of evidence for this result was assessed by GARDE method.The meta-analysis was performed using STATA 14 software and RevMan 5.3.The research method was registered with PROSPERO(CRD42022350926).Results:We included fourteen randomized controlled trials,which including a total of 1,126 participants.Compared with the control group,the experimental group showed significantly improvements in sleep effect as reflected by the reduced PSQI score[mean difference(MD)=-2.47,95%confidence interval(CI)(-3.15,-1.78),I^(2)=92%]with low quality of evidence,and increased TER[risk ratio(RR)=1.23,95%CI(1.14,1.33),I^(2)=40%]with moderate quality of evidence.Compared with hypnotic drugs,CHM-ET significantly reduced the PSQI score[mean difference(MD)=-3.18,95%CI(-5.48,-0.89),I^(2)=73%]with low quality of evidence.The PSQI of CHM-ET significantly decreased compared with single CHM[mean difference(MD)=-3.04,95%CI(-5.84,-0.25),I^(2)=98%]with low quality of evidence,and ET[mean difference(MD)=-2.44,95%CI(-2.87,-2.02),I^(2)=0%]with moderate quality of evidence.No serious adverse reactions were observed.Conclusion:This review suggested that CHM-ET may be an effective treatment for insomnia.However,given the limited quality of the studies and methodologies included in the trials,further rigorous randomized controlled trials are needed for more accurate results.

Effects of Salinity Fluctuation and Dietary Traditional Chinese Herbal Medicines on Survival,Growth and Immunity of Exopalaemon carinicauda

[Objective]The aim of this study was to provide a theoretical basis for the large-scale breeding of Exopalaemon carinicauda. [Method]Effects of salinity fluctuation （S0,S3,S6 and S9 represented salinity fluctuations of 0,3,6 and 9 respectivley） and dietary traditional Chinese herbal medicines （0,1%,2% and 4% respectively） on survival,growth and immunity of E.carinicauda were studied,and its experiment lasted for 60 d. [Result]The results showed that specific growth rate,feed conversion efficiency and superoxide dismutase activity of E.carinicauda in the treatment group with 1% dietary traditional Chinese herbal medicine and S6 salinity fluctuation were higher than those in other treatments,which was significantly higher than the treatment groups with S0,S3 and S9 salinity fluctuation at the same adding level of 1% dietary traditional Chinese herbal medicine. The regression analysis indicated that at S0,S3 and S6 salinity fluctuation,the optimal adding level of dietary traditional Chinese herbal medicines in feeds decreased with the increase of salinity fluctuation,accounting for 2.74%,1.77% and 0.51% respectively. At four adding levels of dietary traditional Chinese herbal medicines,the optimal salinity fluctuation of E.carinicauda also decreased with the increase of dietary traditional Chinese herbal medicines in feeds,accounting for 5.26,4.95,3.54 and 1.97 respectively. [Conclusion]Salinity,dietary traditional Chinese herbal medicines and their interactions have a significant effect on survival,growth and immunity of E.carinicauda,which calls for attentions in the breeding.

Transplanted: Chinese Herbal Medicine in the United States, 1800-1911

Chinese medicine has a long history in the United States, dating back to its colonial period and extending up to the present. This essay focuses on the earliest generation of practitioners of traditional Chinese medicine in the United States. Although acupuncture is the modality most commonly associated with Chinese medicine in today's medical marketplace, up until the 1970s, Chinese healers in the United States typically specialized in herbalism. Well before mass emigration from China to the United States began, Chinese material medica crossed the oceans, in both directions: Chinese medicinal teas and herbs came west while Appalachian ginseng went east. Beginning in the 1850s, Chinese immigrants came to the United States and transplanted their health practices, sometimes quite literally by propagating medicinal plants in their adopted home. Over time, Chinese doctors learned how to sell their services to non-Chinese patients by presenting herbalism as “nature's remedies.”

Research Progress in the Application of Chinese Herbal Medicines in Aquaculture： A Review

Due to increasing safety concerns regarding human consumption of fish products, an increasing number of medicinal chemicals are prohibited from use in aquaculture. As a result, Chinese herbal medicines are being increasingly used, coining the use of the term ＂green medicine.＂ Research shows that Chinese herbal medicines have many beneficial effects on fish, including growth promotion, enhancement of disease resistance, and improvement in meat quality. Many effective ingredients have been discovered in Chinese herbal medicines, which function to promote feed intake, improve meat flavor, and increase digestive enzyme activity. They also regulate and participate in processes that improve the specific and non-specific immunity of fish; however, the composition of Chinese herbal medicines is very complex and it is often difficult to identify the effective ingredients. This article reviews the latest research and application progress in Chinese herbal medicines regarding growth and feed utilization, immunity and disease resistance, and the meat quality of cultured fish. It also discusses research on the chemical constituents of classical Chinese medicinal herbs and problems with the application of Chinese herbal medicines in fish culture. This article concludes by proposing that future studies on Chinese herbal medicines should focus on how to cheaply refine and extract the effective ingredients in classical Chinese medicinal herbs, as well as how to use them efficiently in aquaculture.
