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.

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.

A meta-analysis of Chinese herbal medicines for vascular dementia

OBJECTIVE： To investigate the efficacy and safety of Chinese herbal medicines in the treatment of patients with vascular dementia. DATA RETRIEVAL： We retrieved publications from Cochrane Library （2004 to July 2011）, PubMed （1966 to July 2011）, the Chinese Science and Technique Journals Database （1977 to July 2011）, the China National Knowledge Infrastructure （1979 to July 2011）, Google Scholar （July 2011）, and the Chinese Biomedical Database （1977 to July 2011） using the key words ＂Chinese medicine OR Chinese herbal medicine＂ and ＂vascular dementia OR mild cognition impair OR multi-infarct dementia OR small-vessel dementia OR strategic infarct dementia OR hypoperfusion dementia OR hemorrhagic dementia OR hereditary vascular dementia＂. SELECTION CRITERIA： Randomized controlled trials comparing Chinese herbal medicines with placebo/western medicine in the treatment of patients with vascular dementia were included. Diagnostic standards included Diagnostic and Statistical Manual of Mental Disorders-IV, and National Institute of Neurological Disorders and Stroke and Association Internationale pour la Recherche et I＇Enseignement en Neurosciences. Two participants independently conducted literature screening, quality evaluation and data extraction. The quality of each trial was assessed according to the Cochrane Reviewers＇ Handbook 5.0. MAIN OUTCOME MEASURES： Effective rate, Mini-Mental State Examination scores, Hasegawa Dementia Scale scores, and incidence of adverse reactions. RESULTS： We identified 1 143 articles discussing the effects of Chinese medicine on vascular dementia. Thirty-one of these were included in the analysis. These studies involved a total of 2 868 participants （1 605 patients took Chinese medicine decoctions （treatment group）; 1 263 patients took western medicine or placebo）. The results of our meta-analysis revealed that Chinese herbal remedies in the treatment group were more efficacious than the control intervention （relative risk （RR） = 1.27; 95% confidence interval （C/）： 1.18-1.38, P 〈 0.01）. Mini-Mental State Examination scores were higher in patients taking Chinese herbal medicines than in those in the control group （weighted mean difference （WMD） = 2.83; 95%CI： 2.55-3.12, P 〈 0.01）. Patients in the treatment group showed better disease amelioration than those in the control group （Hasegawa Dementia Scale scores; WMD = 2.41, 95%CI： 1.48-3.34, P 〈 0.01）. There were also considerably fewer adverse reactions among those in the treatment group compared with those in the control group （RR = 0.20, 95%CI： 0.08-0.47, P 〈 0.01）. CONCLUSION： Chinese herbal medicine appears to be safer and more effective than control measures in the treatment of vascular dementia. However, the included trials were generally low in quality. More well-designed, high-quality trials are needed to provide better evidence for the assessment of the efficacy and safety of Chinese medicines for vascular dementia.

Regulatory effect of a Chinese herbal medicine formula on nonalcoholic fatty liver disease

BACKGROUND Non-alcoholic fatty liver disease(NAFLD)has become a major cause of chronic liver disease.The Chinese herbal medicine(CHM)Dachaihu decoction(DCHD)has been proved to treat NAFLD with good efficacy in previous studies.Based on the TCM principle of formula formation,we divided DCHD into soothing liver part,invigorating spleen part,and dredging intestine part.Marshall officially proposed the concept of“intestinal-hepatic axis”,which systematically explains the interactions between the intestine and liver.We hypothesized that the effect of CHM on NAFLD is achieved by regulating the liver and intestine.Thus,we aimed to investigate the possible effect of a CHM formula on NAFLD in a rat model.AIM To investigate the effects of a CHM formula(a decoction of Chinese thorowax root,scutellaria root,and white peony root)on NAFLD and its regulatory effect on the“intestinal-liver”axis.METHODS Sixty rats were randomly divided into control,model,pioglitazone hydrochloride(PH),and CHM(a decoction of Chinese thorowax root,scutellaria root,and white peony root)groups.An NAFLD rat model was established using a high-fat highfructose diet for 16 wk.From the 13th week,rats were administered with PH or a decoction of Chinese thorowax,scutellaria,and white peony root(CHM group)for 4 wk.Rats in the control group and model group were administered with an equal volume of distilled water.At the end of the study,blood was collected via the abdominal aorta.Liver tissues were harvested and any morphological changes were observed by hematoxylin-eosin(HE)staining,Oil red O staining,and Masson staining.In addition,blood lipids,liver function markers,and triglyceride(TG)in liver tissues were analyzed.The levels of transforming growth factor-β1(TGF-β1),tumor necrosis factor-α(TNF-α),Toll-like receptor-4(TLR4),and nuclear factor-kappa B(NF-кB)in liver tissues and secreted immunoglobulin A(sIgA)in intestinal tissues were analyzed by ELISA,and protein and mRNA expression of occludin and zonula occludens-1(ZO-1)in the intestine were measured using Western blot and reverse transcriptionquantitative polymerase chain reaction,respectively.The endotoxin level in plasma was detected by endpoint chromogenic assay.RESULTS Compared to the normal control group,the liver coefficient,serum TG,total cholesterol(TC),low density lipoprotein(LDL),aspartate aminotransferase(AST),and alanine aminotransferase(ALT),blood glucose,plasma endotoxin,and the levels of TG,TNF-α,TGF-β,NF-kB,and TLR4 in liver tissues increased significantly in the model group,while serum high density lipoprotein(HDL),intestinal sIgA,and protein and mRNA expression of occludin and ZO-1 decreased significantly in the model group(P<0.01).PH and CHM attenuated the elevated liver coefficient,serum TG,TC,LDL,AST,and ALT,blood glucose,plasma endotoxin,and the levels of TG,TNF-α,TGF-β,NF-kB,and TLR4 in liver tissues and increased serum HDL levels compared to the model group(P<0.01).Intestinal sIgA and the protein and mRNA expression of intestinal occludin and ZO-1 were significantly increased in the PH group compared to the model and CHM groups(P<0.01).CONCLUSION The decoction of Chinese thorowax root,scutellaria root,and white peony root is beneficial in regulating lipid metabolism and liver function,which indicates that it has a good effect on the liver.To a certain extent,this CHM formula can affect both the liver and intestine,while its effect on the liver is superior to that on the intestine.

[Objectives]To explore the effects of nano compound Chinese herbal medicine feed additive on growth performance,meat quality and disease resistance of chickens.[Methods]Chickens were fed with nano compound Chinese herbal medicine feed additive developed by Hunan Polytechnic of Environment and Biology,including 120 chickens in the treatment group and 120 chickens in the control group(CK).The growth performance indices(body weight gain,feed to gain ratio and slaughter index),meat quality indices(pH value,color,drip loss,shear force)and disease resistance indices(morbidity and mortality)of the chickens in the treatment and CK groups were recorded and determined,respectively.[Results]The inclusion of 2%nano compound Chinese herbal medicine feed additive in the diet significantly increased the growth rate,reduced the feed-to-gain ratio and improved the meat quality of the chickens.Supplementing Chinese herbal medicine could increase the pH value and reduce the drip loss and shear force of chicken meat.At the same time,the body's immune function,antioxidant level and resistance against diseases of the chickens fed with nano compound Chinese herbal medicine feed additive were improved.[Conclusions]The inclusion of nano compound Chinese herbal medicine feed additive in the diet can improve the growth performance,meat quality and disease resistance of chickens.

Integrative techniques using acupuncture,Chinese herbal medicine,diet,and supplements for polycystic ovary syndrome:a case report

Patients with a diagnosis of polycystic ovary syndrome （PCOS） are on the rise. About 4%-12% of women are currently estimated to have this condition. It is hypothesized that PCOS appears in women who have long-standing insulin resistance （1R）, which leads to high androgen and testosterone levels; this ultimately disrupts their menstrual cycles. Some researchers attribute IR to genetic factors, although there have been only minute changes in the human genome in the past 20 000 years. However, even with a stable gene pool, genes can be turned on and offby the environment, food and air quality and toxin exposure.

Chinese herbal medicine for hand-foot-and-mouth disease in children: An overview of systematic reviews

Objective:To summarize the use of Chinese herbal medicines (CHM) for the treatment of hand-foot-and-mouth disease (HFMD) in children and to provide high-level evidence for clinical decision-making.Methods:We conducted an overview of systematic reviews (SRs).Two English-language and four Chinese-language electronic databases were searched from inception to March 31,2018.Published SRs and meta-analyses evaluating CHM use in children with HFMD and reporting clinically-relevant outcomes such as time to fever resolution were eligible for inclusion in this overview.Reviews were accepted if the intervention featured CHM with or without other treatment.Two authors evaluated the methodological quality of the included SRs by using ASMTAR and ROBIS.Results:Thirty SRs comprising 90 244 children with HFMD were included in this overview of SRs.All SRs were published in Chinese between 2011 and 2017.All intervention arms received CHM with or without conventional treatment and were compared against control arms receiving no treatment,conventional treatment alone,or placebo.All 30 reviews reported the time to fever resolution and results demonstrated that CHM had a greater benefit in reducing fever compared with controls.Twenty-three reviews reported the time to rash resolution which presented similar results.Fourteen SRs reported the time to oral ulcer healing and CHM demonstrated a significantly reduced time to resolution compared to controls.The quality of the included SRs was low to moderate as assessed by the AMSTAR tool.Conclusion:Published reviews demonstrated potential benefits of CHM in children with HFMD.Overall,the methodological quality of reviews included in this overview of SRs was low and our findings should be interpreted with caution.We would strongly recommend that future SRs be designed and reported rigorously following PRISMA in order to provide more robust evidence on which to base clinical guidance.

Efficacy and Safety of Chinese Herbal Medicines Combined with Chemical Drugs for Alzheimer's Disease:A Systematic Review and Meta-Analysis

Objective:To evaluate the efficacy and safety of Chinese herbal medicines(CHMs)combined with chemical drugs for the treatment of Alzheimer's disease(AD).Materials and Methods:Databases were searched to retrieve randomized controlled trials(RCTs)of CHMs combined with tacrine,galantamine,rivastigmine,donepezil,or memantine,following strict inclusion and exclusion criteria.Only research papers published in English,Chinese,and Japanese were considered.The primary outcome was the mini-mental state examination(MMSE)score and the secondary outcomes were AD assessment scale cognitive subscale(ADAS-Cog)score and safety evaluation.Meta-analysis was carried out using Rev Man 5.3 and subgroup analysis was conducted to identify the sources of heterogeneity.Results:A total of 15 RCTs with 1386 participants were included in this study.Only donepezil was used in the retrieved literature.Meta-analyses showed that the combination of CHMs with donepezil led to significant improvement in the MMSE score(Z=9.45;P<0.00001;weighted mean difference[WMD]=2.68,95%confidence interval[CI]:2.12-3.24)and a significant decrease in the ADAS-Cog score(Z=5.53;P<0.00001;WMD=-3.79;95%CI:-5.13--2.44).Safety evaluation demonstrated that these combination treatments relieved adverse events such as insomnia(risk ratio[RR]=0.20,95%CI:0.06-0.68;P=0.01)and hive(RR=0.10;95%CI:0.01-0.73;P=0.02).Conclusions:The combination of CHMs with a chemical drug like donepezil led to significant improvements in patient cognition as well as a better safety profile when compared to the application of a chemical drug alone.

Integration of multi-omics in investigations on the mechanisms of action of Chinese herbal medicine interventions in metabolic diseases

The rapid development of bioinformatics has provided novel approaches and methods for exploring the mechanisms of disease treatment via Chinese herbal medicines.Compound Chinese herbal medicines formulas have complex compositions and are characterized by their multiple constituents and diverse array of biological targets.Therefore,the mechanisms of action of most compound Chinese herbal medicines formulas cannot be adequately explained using a single pathway.Omics technologies describe high-throughput-based analytical and detection techniques,which include transcriptomics,proteomics,and metabolomics and provide multilayer parameter information that can be integrated to characterize the overall relationships involved in the therapeutic effects of Chinese herbal medicines formulas.Through their combination with network biology and drug effect networks,omics technologies also enable investigations into the mechanisms of disease treatment in traditional Chinese medicine.The integration of multiple omics technologies is in line with the concept of holism in traditional Chinese medicine and provides an approach for combining modern science and technology with traditional Chinese medicine theories.In recent years,omics technologies have been widely used to elucidate the mechanisms of action of Chinese herbal medicines.The latest studies employing multi-omics integration for investigating the mechanisms of action of Chinese herbal medicines interventions in metabolic diseases have devoted greater attention to in-depth explorations of disease pathogenesis.This paper provides a review of the following multi-omics technologies,which are used in research on the treatment of common metabolic diseases(e.g.,type-2 diabetes mellitus,nonalcoholic fatty liver disease):network pharmacology combined with metabolomics,16S rRNA sequencing combined with transcriptomics,16S rRNA sequencing combined with metabolomics,and 16S rRNA sequencing combined with network pharmacology and metabolomics.

Isolation and Identification of the Pathogen Causing Skin Ulcer Disease in Cynoglossus semilaevis Günther and Its Sensitivity to Chinese Herbal Medicine

In this study, the pathogen causing skin ulcer disease in Cynoglossus semilaevis Gunther was isolated for morphological observation, physiological and bio- chemical identification. According to the result, the isolated pathogen was identified as Vibrio harveyi. The results of recurrent infection of C. semilaevis Gonther showed that the pathogen was strongly pathogenic to C. semilaevis Gunther. In or- der to explore the pathogenesis, outer membrane protein （OMP） gene of C. semi- laevis Gunther was detected by PCR. The results showed that all the three repre- sentative strains harbored OMP gene. According to the results of sensitivity test of the pathogen to Chinese herbal medicine, Galla Chinensis, Fructus Mume, Fructus Hippophae and Lignum Sappan exerted strong antibacterial effects against V. harveyr, Pericarpium Granati exhibited slight antibacterial effect against V. harveyi; Pericarpium Citri Reticulatae, Rhizoma Acori GramineL Herba Houttuyniae, Herba Portulacae, Herba Andrographis, Eucalyptus globulus Labill. and Herba Menthae Heplocalycis had little effect on V. harveyi. Galla Chinensis, Fructus Mume, Fructus Hippophae and Lignum Sappan were prepared into three prescriptions, among which prescription 1 （Galla Chinensis ＋ Fructus Mume） exhibited the strongest antibacterial effect.

Herbal medicines and nonalcoholic fatty liver disease

Nonalcoholic fatty liver disease(NAFLD), which is characterized by excessive fat accumulation in the liver of patients who consume little or no alcohol, becomes increasingly common with rapid economic development. Long-term excess fat accumulation leads to NAFLD and represents a global health problem with no effective therapeutic approach. NAFLD is considered to be a series of complex, multifaceted pathological processes involving oxidative stress, inflammation, apoptosis, and metabolism. Over the past decades, herbal medicines have garnered growing attention as potential therapeutic agents to prevent and treat NAFLD, due to their high efficacy and low risk of side effects. In this review, we evaluate the use of herbal medicines(including traditional Chinese herbal formulas, crude extracts from medicinal plants, and pure natural products) to treat NAFLD. These herbal medicines are natural resources that can inform innovative drug research and the development of treatments for NAFLD in the future.

Advances in traditional Chinese medicine for liver disease therapy in 2020

Liver diseases are gradually becoming a serious threat to human health worldwide.Although a number of medications have been introduced for the prophylaxis,diagnosis,and treatment of liver diseases,several limitations and challenges remain.Traditional Chinese medicine is frequently used to treat liver diseases and well known to protect hepatocytes and inhibit inflammation,oxidative stress,and fibrosis.However,given the complex composition of traditional Chinese medicine,clarifying the mechanisms behind its curative and protective effects is difficult.In this review,research progress on traditional Chinese medicine for the treatment of liver diseases in 2020 is summarized on the basis of the literature available in the PubMed database.Herbal extracts derived from traditional Chinese medicine,including flavonoids,polysaccharides,saponins,and alkaloids,and Chinese medicinal formulas,such as the classic decoctions Chaihu Shugan powder,Linggui Zhugan decoction,and Huanglian Jiedu decoction,have shown promising therapeutic efficacy in liver disease treatment.We summarized the findings of several studies on the active ingredients of traditional Chinese herbs used for liver disease treatment in 2020,focusing mainly on their ability to confer antiviral effects to treat hepatitis,regulate antioxidant levels and apoptosis to treat liver injury,inhibit inflammation and improve dysfunctions in amino acids and energy metabolism to treat alcoholic liver disease,reduce hepatic lipid deposition to treat nonalcoholic fatty liver disease,promote activated hepatic stellate cells to treat liver fibrosis,inhibit the proliferation or promote the apoptosis of liver cancer cells to treat hepatocellular carcinoma,and improve bile acid metabolism to treat cholestasis.

Effects of Chinese Herbal Medicine Additives on Growth,Immunity and Antioxidation of Chickens

Chinese herbal medicine additives can not only directly improve the growth performance of chickens,but also indirectly affect the growth of chickens by enhancing the antioxidant capacity,immunity and disease resistance of the body,and eliminating diseases and adverse factors,thereby improving the growth performance of chickens.In the context of the current national prohibition of adding antibiotics to feed,the research and application of Chinese herbal medicine additives are of practical significance to eliminate the long-term use of antibiotics as chicken feed additives and reduce the threat to the environment and human health.For this reason,the research related to the substitution of Chinese herbal medicine for antibiotics is made a brief introduction to provide a reference in research and production practice.

Chinese herbal medicines for treating ulcerative colitis via regulating gut microbiota-intestinal immunity axis

Ulcerative colitis(UC)is one of types of inflammatory bowel disease with high recurrence.Recent studies have highlighted that microbial dysbiosis as well as abnormal gut immunity are crucial factors that initiate a series of inflammatory responses in the UC.Modulating the gut microbiota-intestinal immunity loop has been suggested as one of key strategies for relieving UC.Many Chinese herbal medicines including some of single herb,herbal formulas and the derived constituents have been reported with protective effect against UC through modulating gut microbiome and intestinal immunity.Some clinical trials have shown promising results.This review thus focused on the current knowledge on using Chinese herbal medicines for treating UC from the mechanism aspects of regulating intestinal homeostasis involving microbiota and gut immunity.The existing clinical trials are also summarized.

Can TCM Treatment be Performed on the Basis of Differential Diagnosis of the Diseases Instead of the Syndromes?

Great advances have been achieved in the integration of western and traditional Chinese medicine (TCM).More and more TCM physicians in their practice accept the term 'differential diagnosis of the diseases' instead of the syndromes since western medicine has been introduced into the TCM circle.
