An effective method is developed for analysis of trace lead and cadmium in Chinese herbal medicines and their decoctions by graphite furnace atomic absorption spectrometry (GFAAS). The effects of analytical conditions on absorbance were investigated and optimized. A water-dissolving capability for Pb and Cd was investigated, and the contents of different species in five Chinese herbal medicines and their decoctions were analyzed. The content ratios (kow) of n-octanol-soluble Pb or Cd to water-soluble Pb or Cd were evaluated, and the distribution of Pb and Cd in water decoction at stomach and intestine acidities was developed, in the first time. The contents of water-soluble Pb and Cd, n-octanol-soluble Pb and Cd, and their content ratios were related with the kind of medicine and the acidity of the decoction. The proposed method has the advantages of simple operation, high sensitivity and high speed, with 3 σ detection limits of 4.2 pg for Pb and 0.1 pg for Cd.展开更多

文摘Xiexin decoctions(XXDs)display beneficial anti-inflammatory and anti-diabetic effects,which raises interests on this group of formulae for broad clinical applications.However,there was no report about systematic analysis of XXDs to elucidate the constitution of chemical components,which hampers further investigations on the therapeutic values of XXDs.In this work,crude herbs were extracted and prepared to obtain the XXDs for systemic analysis on their chemical compositions,according to the information described in the ancient Zhang Zhongjing’s herbal formulae.LC-MS analysis of five XXDs was carried out to facilitate recognition of the source herbs for compounds in the mixture.A total number of 93 compounds were identified through our methods and their chemical classes encompassed five major groups,including protoberberine alkaloids,flavonoids,stilbenes,anthraquinones and saponins.Our current work provided important information about material basis for pharmacological studies on XXDs and would help shed light on relationships between chemical compositions and therapeutic effects.
文摘Lead and cadmium in herbal medicines are highly toxic to living organisms even in low concentrations. An effective method is developed for analysis of trace lead and cadmium in Chinese herbal medicines and their decoctions by graphite furnace atomic absorption spectrometry (GFAAS). The effects of analytical conditions on absorbance were investigated and optimized. A water-dissolving capability for Pb and Cd was investigated, and the contents of different species in five Chinese herbal medicines and their decoctions were analyzed. The content ratios (kow) of n-octanol-soluble Pb or Cd to water-soluble Pb or Cd were evaluated, and the distribution of Pb and Cd in water decoction at stomach and intestine acidities was developed, in the first time. The contents of water-soluble Pb and Cd, n-octanol-soluble Pb and Cd, and their content ratios were related with the kind of medicine and the acidity of the decoction. The proposed method has the advantages of simple operation, high sensitivity and high speed, with 3 σ detection limits of 4.2 pg for Pb and 0.1 pg for Cd.

文摘During the late Qing dynasty(1840 A.D.-1912 A.D.),a large quantity of Western medicines entered China,which continuously impacted the traditional Chinese medicine(TCM)market and revealed the shortcomings of Chinese medicines.Some personages in the TCM community followed the trend of learning from the West,and attempted to reform TCM,with the improvement on decoction becoming an important aspect of this effort.Through debates and trials,the improvement on decoction underwent three stages of conceptual evolution:“taking Chinese medicines as the foundation and referring to the dosage forms of Western medicines”,“introducing Western techniques to serve the preparation of decoctions”and“integrating the theories of TCM and Western medicine to improve decoctions”.The study highlights the effective complementarity between modern TCM and Western medicine in the field of pharmacy,and provides valuable experience and support for the reevaluation of the value of TCM in contemporary society.

文摘BACKGROUND Chronic atrophic gastritis(CAG)is a clinically refractory gastric disease often characterized by high recurrence rates and adverse drug reactions.Anwei decoction(AWD),a traditional Chinese medicine formula,has been shown to significantly improve clinical symptoms in patients with CAG,as demonstrated by a multicenter cohort study(overall effective rate:82.5%,P<0.01).However,the unclear molecular mechanisms and therapeutic targets of AWD limit its international acceptance.AIM To investigate the therapeutic mechanisms of AWD against CAG from an integrated perspective.METHODS In this study,N-methyl-N’-nitro-N-nitrosoguanidine was used to establish a CAG rat model.Serum-derived constituents transferred from AWD were first identified using ultra-high-performance liquid chromatography coupled with tandem mass spectrometry.The concentrations of inflammatory cytokines in serum samples were determined by enzyme-linked immunosorbent assay.Moreover,gastric mucosal tissues were analyzed by quantitative realtime polymerase chain reaction to measure messenger RNA(mRNA)levels of the NLRP3 inflammasome.Western blotting was used to detect the protein expression of NLRP3,caspase-1,and interleukin(IL)-1β.To elucidate the regulatory mechanisms underlying AWD treatment,structural alterations of the gut microbiota(GM)and associated metabolites were analyzed using integrated high-throughput sequencing(16S rRNA)and liquid chromatography-mass spectrometry based untargeted metabolomics.This comprehensive approach systematically clarified AWD’s multi-target therapeutic mechanisms against CAG.RESULTS AWD notably reduced serum levels of pro-inflammatory cytokines,such as IL-1β,IL-18,tumor necrosis factor-α,and lipopolysaccharide,demonstrating significant statistical differences(all P<0.01).Additionally,AWD substantially inhibited NLRP3 mRNA expression in gastric mucosal tissue(P<0.01)and concurrently decreased the protein abundance of NLRP3,IL-1β,and caspase-1(all P<0.01),thereby suppressing inflammasome signaling activation.GM analysis indicated that AWD intervention significantly increased the relative abundance of beneficial bacteria.Associated microbial metabolites likely inhibited the NLRP3 inflammasome pathway by modulating immune cell function.Non-targeted metabolomics further indicated that AWD exerted anti-inflammatory effects by regulating critical metabolic pathways,including the Kaposi’s sarcoma-associated herpesvirus infection pathway,autophagy processes,and glycosylphosphatidylinositol-anchor biosynthesis.CONCLUSION AWD alleviates the pathological progression of CAG through multi-target synergistic mechanisms.On one hand,AWD directly suppresses gastric mucosal inflammation by inhibiting NLRP3 inflammasome activation.On the other hand,AWD remodels intestinal microbiota-metabolite homeostasis,enhances intestinal barrier function,and regulates mucosal immune responses.

文摘Background:ZhiZi-BoPi Decoction(ZZBPD),a traditional prescription for liver and gallbladder protection,has garnered significant clinical interest due to its hepatoprotective properties.Despite its proven efficacy in mitigating intrahepatic cholestasis,the precise mechanisms underlying its therapeutic effects remain inadequately understood.This study aims to comprehensively investigate the pharmacological mechanisms underlying the therapeutic effects of ZZBPD in cholestatic liver injury(CLI).Methods:Firstly,we evaluated the hepatoprotective effects of ZZBPD on mice with CLI induced byα-naphthylisothiocyanate(ANIT),by measuring biochemical markers,inflammatory factors,and bile acid levels.Subsequently,we employed network pharmacology and single-cell RNA sequencing(scRNA-seq)to identify key targets and potential signaling pathways for the prevention and treatment of CLI.Finally,we further validated the mechanism of action of ZZBPD on these key targets through molecular docking,western blotting,and immunofluorescence techniques.Results:ZZBPD notably improved serum liver function,reduced hepatic inflammation,and restored bile acid balance.Through network pharmacology and scRNA-seq analysis,48 core targets were identified,including TNF,IL-6,and NFKB1,all of which are linked to the IL-17 and NF-κB signaling pathways,as shown by KEGG enrichment analysis.Molecular docking further confirmed stable interactions between ZZBPD’s key active components and molecules such as IL-6,IL-17,and NF-κB.Additionally,western blotting and immunofluorescence validated the downregulation of IL-17 and NF-κB protein expression in liver tissue.Conclusion:ZZBPD effectively treats CLI by activating pathways related to the bile acid receptor FXR,while also modulating the IL-17/NF-κB signaling pathway.This dual action enhances bile secretion and alleviates liver inflammation.These findings offer important insights into the pharmacological mechanisms of ZZBPD and underscore its potential as a promising therapeutic for CLI.

文摘Since 2016,a number of studies have been published on standard decoctions used in Chinese medicine.However,there is little research on statistical issues related to establishing the quality standards for standard decoctions.In view of the currently established quality standard methods for standard decoctions,an improvement scheme is proposed from a statistical perspective.This review explores the requirements for dry matter yield rate data and index component transfer data for the application of two methods specified in‘‘Technical Requirements for Quality Control and Standard Establishment of Chinese Medicine Formula Granules,"which include the average value plus or minus three times the standard deviation (■±3SD) or 70%to 130%of the average value (■±30%■).The square-root arcsine transformation method is used as an approach to solve the problem of unreasonable standard ranges of standard decoctions.This review also proposes the use of merged data to establish a standard.A method to judge whether multiple sets of standard decoction data can be merged is also provided.When multiple sets of data have a similar central tendency and a similar discrete tendency,they can be merged to establish a more reliable quality standard.Assuming that the dry matter yield rate and transfer rate conform to a binomial distribution,the number of batches of prepared slices that are needed to establish the standard decoction quality standard is estimated.It is recommended that no less than 30 batches of prepared slices should be used for the establishment of standard decoction quality standards.

文摘Objective This study aimed to study the effects of different crystalline states of Sheng Shigao(raw gypsum,RG)and its inorganic elements on the antipyretic efficacy of Baihu Decoction(BHT).Methods RG samples calcined at different temperatures were prepared.The phase composition of RG and Duan Shigao(calcination of gypsum,CG)as well as the changes in phase composition before and after adding water to RG calcined at specific temperatures,were determined using X-ray diffraction(XRD).A fever model was established by subcutaneously injecting 20%yeast suspension(10 mL·kg~(-1))into the backs of rats.The effects of BHT containing RG in different crystalline states on rat body temperature were measured.Serum levels of IL-1β,IL-6,and hypothalamic prostaglandin E2(PGE_2)were detected using ELISA.Serum Ca~(2+)levels were measured using a microplate method.The content of trace elements in RG and CG and the corresponding freeze-dried BHT powder was determined using inductively coupled plasma mass spectrometry(ICP-MS).The complexation of representative inorganic elements with mangiferin,a major active component in BHT,was investigated using UV-Vis spectroscopy and fluorescence spectroscopy.A validation model was established using RAW264.7 mouse macrophages.Drug-containing serum of BHT with different inorganic elements was prepared,and the nitric oxide(NO)levels in the cell supernatant of different treatment groups were measured using the Griess method.The mRNA levels of IL-6,TNF-α,and PGE2in each group were detected using qPCR(real-time fluorescent quantitative PCR).Results After calcination,the phase composition of RG changed,and the content of inorganic elements in RG,CG170(RG calcined at 170°C),and CG350(RG calcined at 350°C)showed similar trends.Compared with RG,the content of Ca,Sr,Al,and Na in CG changed significantly.Compared with BHT,the content of Ca,Sr,Si,and Na in CG changed significantly when incorporated into the formula.Intermolecular interactions confirmed strong binding between mangiferin and Cu~(2+)and Al~(3+).Cu~(2+)and Fe~(3+)exhibited fluorescence quenching effects on mangiferin solution,while Al~(3+)and Zn~(2+)showed strong fluorescence enhancement,with fluorescence intensity increasing by 120-fold and 30-fold,respectively.In vitro evaluation of synergistic anti-inflammatory effects confirmed that Ca,Fe,Cr,Al,and Si exhibited synergistic anti-inflammatory effects.Conclusion The crystalline state of RG has little effect on its antipyretic properties,while Ca,Sr,Na,Fe,and Al are likely the key material bases influencing its efficacy.

文摘Lingguizhugan Decoction(LGZG)demonstrates significant efficacy in treating various cardiovascular diseases clinically,yet its precise mechanism of action remains elusive.This study aimed to elucidate the potential mechanisms and effects of LGZG on isoproterenol(ISO)continuous stimulation-induced chronic heart failure(CHF)in mice,providing direct experimental evidence for further clinical applications.In vivo,continuous ISO infusion was administered to mice,and ventricular myocytes were utilized to explore LGZG's potential mechanism of action on theβ1-adrenergic receptor(β1-AR)/Gs/G protein-coupled receptor kinases(GRKs)/β-arrestin signaling deflection system in the heart.The findings reveal that LGZG significantly reduced the messenger ribonucleic acid(mRNA)expression of hypertrophy-related biomarkers[atrial natriuretic peptide(ANP)and B-type natriuretic peptide(BNP)]and improved cardiac remodeling and left ventricular diastolic function in mice with ISO-induced CHF.Furthermore,LGZG inhibited the overactivation of Gs/cyclic adenosine monophosphate(c AMP)/protein kinase A(PKA)signaling and downregulated the downstream transcriptional activity of c AMP-response element binding protein(CREB)and the expression of the coactivator CBP/P300.Notably,LGZG downregulated the expression ofβ-arrestin1 and GRK 2/3/5 while upregulating the expression ofβ1-AR andβ-arrestin2.These results suggest that LGZG inhibits Gs/c AMP/PKA signaling andβ-arrestin/GRK-mediated desensitization and internalization ofβ1-AR,potentially exerting cardioprotective effects through the synergistic regulation of theβ1-AR/Gs/GRKs/β-arrestin signaling deflection system via multiple pathways.

文摘Severe fever with thrombocytopenia syndrome(SFTS)is a novel emerging acute infectious disease caused by severe fever with thrombocytopenia syndrome virus(SFTSV),characterized by high fever and thrombocytopenia.It has been proved that traditional Chinese medicine(TCM)has displayed definite therapeutic effects on viral hemorrhagic fever,indicating its potential to treat SFTS.In this study,SFTS-relative key targets were predicted via gene ontology(GO)analysis and kyoto encyclopedia of genes and genomes(KEGG)enrichment analysis.Molecular docking was then used to select stable binders.Molecules matched TCMs were identified,and a new prescription,Qingqi Guxue decoction(QQGX),was formulated to clear heat and nourish blood,with a resulting drug composition network.We explored the optimal drug proportion for QQGX.Through an in-depth study of molecular mechanisms,we found that QQGX induces S phase arrest by promoting the degradation of cyclin A2(CCNA2)and cyclin-dependent kinase 2(CDK2),thereby inhibiting SFTSV replication.Finally,we verified the effectiveness and safety of QQGX based on the mouse liver bile duct organoid model infected with SFTSV.In summary,our study prepared a TCM decoction using the method of network pharmacology.This decoction has a significant inhibitory effect on the replication of SFTSV and provides a new treatment strategy for hemorrhagic fever with TCM.

文摘BACKGROUND The development of slow transit constipation(STC)is associated with intestinal barrier damage.Huangqi decoction(HQD)is effective in treating STC,but me-chanisms are unclear.AIM To investigate whether HQD alleviates STC by downregulating the nuclear factorκB(NF-κB)signaling pathway and restoring intestinal barrier function.METHODS KM mice were divided into control,model,and HQD treatment groups.Fresh colonic tissues were collected for single-cell RNA sequencing and spatial tra-nscriptome sequencing.The expressions of claudin-1,mucin 2,and NF-κB P65 proteins were detected by immunohistochemistry.In vitro experiments evaluated the effects of HQD on the LS174T cell line.RESULTS HQD improved intestinal motility,restored mucosal epithelium function and morphology.Single-cell RNA sequencing and spatial transcriptome sequencing data showed a reduction in goblet cells,decreased mucin 2 secretion,and activated apoptotic pathways in STC mice.The population of intestinal stem cells was reduced,and proliferation along with Wnt/β-catenin pathways were inhibited.STC also altered the distribution of intestinal cell states,increasing immune-associated Enterocyte_C3.Aberrant NF-κB pathway activation was noted across various cell types.After HQD treatment,NF-κB pathway activity was down-regulated,while cell proliferation pathways were up-regulated,alongside an increase in Enterocyte_C1 related to material transport.Immunocytochemical,Western blot,and immunohistochemistry analyses confirmed NF-κB pathway activation in goblet cells of STC mice,with HQD inhibiting this aberrant activation.CONCLUSION STC involves intestinal mucosal barrier damage.HQD may treat STC by suppressing NF-κB signaling in epithelial cells,restoring intestinal epithelial cell function,and promoting mucosal barrier repair.

文摘Traditional Chinese medicine has unique advantages in preventing and treating COVID-19,and Fuzheng Jiedu decoction(FZJDD)was reported to be effective against COVID-19 in clinical trials.To investigate the potential mechanisms and material basis of FZJDD against SARS-CoV-2,we performed SARS-CoV-2 target protein inhibition analyses and a metabolite full spectrum analysis of FZJDD.Interestingly,FZJDD was found to block the binding of SARS-CoV-2 Spike protein with the receptor ACE2 and inhibit the activity of SARS-CoV-23CLpro.Moreover,FZJDD can regulate the TNF and the MAPK signaling pathway to inhibit the inflammatory response and alleviate the“cytokine storm”.A total of 298 compounds were identified in FZJDD,among them,caffeic acid and octyl gallate were found to be the potential therapeutic agents of FZJDD.Importantly,FZJDD can broadly inhibit coronavirus infection,including SADS-CoV and porcine epidemic diarrhea virus(PEDV)live viruses,SARS-CoV,MERS-CoV,and SARS-CoV-2 mutant pseudotyped viruses,which might be ascribed to the broad-spectrum anti-coronavirus activity of caffeic acid and octyl gallate.In conclusion,this study reveals the mechanisms and material basis of FZJDD against SARS-CoV-2 and identifies the broadspectrum anti-coronavirus activity of FZJDD for the first time.Our data provide empirical evidence for the development and application of FZJDD.
文摘Objective:To evaluate the therapeutic effect of Tianma Gouteng Decoction combined with Betahistine Mesylate in patients with posterior circulation ischemic vertigo(PCI).Methods:Eighty-two patients with PCI who visited the hospital from February 2024 to February 2025 were selected as samples and randomly divided into two groups.Group A received Tianma Gouteng Decoction combined with Betahistine Mesylate,while Group B received only Betahistine Mesylate.The efficacy,syndrome scores,hemodynamics,and quality of life indicators were compared between the two groups.Results:The efficacy of PCI treatment in Group A was higher than that in Group B(P<0.05).The syndrome scores in Group A were lower than those in Group B(P<0.05).The peak systolic velocity(PSV)of the basilar artery and left and right vertebral arteries in Group A were higher than those in Group B(P<0.05).The quality of life(SF-36)score in Group A was higher than that in Group B(P<0.05).Conclusion:Tianma Gouteng Decoction combined with Betahistine Mesylate is effective and feasible in the treatment of PCI,with improved hemodynamic indicators and reduced disease scores.
文摘Chemotherapy-induced intestinal mucositis(IM)is a prevalent complication affecting up to 80%of cancer patients undergoing treatment.Current therapies focus on symptomatic relief rather than addressing the underlying mechanism.Recent advances in integrative medicine highlight the potential of traditional Chinese medicine formulations as alternatives or adjuncts to existing therapies.In this context,this editorial discusses the recent results of a study published by Qiu et al,which investigates the multifaceted potential of modified Pulsatilla decoction(PD),a formulation of PD with licorice(Glycyrrhiza uralensis)and Ejiao(Colla corii asini),on 5-fluorouracil-induced IM in mice to alleviate clinical symptoms including diarrhea,weight loss,and intestinal damage.A series of histological,biochemical,bioinformatic,and microbiological assays evaluated body weight,diarrhea scores,inflammatory cytokine profiles,oxidative stress modulation,and microbiota composition.The findings indicated a reduction in diarrhea and oxidative stress,as well as an improvement in body weight and intestinal histopathology.Furthermore,the modified PD suppressed the TLR4/MyD88/nuclear factor kappa-B inflammatory pathway and down-regulated key proinflammatory cytokines.Moreover,the study underscores the role of gut microbiota in IM pathogenesis.Modified PD treatment reshaped microbial diversity by promoting beneficial genera such as Bacteroides acidifaciens while suppressing pathogenic species like Salmonella.These findings suggest that the therapeutic effects of the modified PD extend beyond inflammation modulation to encompass microbiome reprogramming and mucosal barrier repair.Although the study provides significant insights,several limitations still prevail.The broader implications of modified PD in gastrointestinal disorders and integrative oncology need further exploration.

文摘OBJECTIVE:To evaluate the effect of Fuzi Lizhong decoction(附子理中汤)on intestinal flora,serum inflammatory factors,and hypoxia inducible factor-1α(HIF-1α)in patients with colorectal cancer associated with spleen and kidney Yang deficiency.METHODS:A total of 100 patients diagnosed with advanced colorectal cancer were randomly divided into two groups:a control group(CON,50)and a Traditional Chinese Medicine(TCM)group(n=50).The control group received treatment with the Capecitabine+Oxaliplatin(CAPEOX)regimen,while the TCM group received the same regimen along with Fuzi Lizhong decoction for six weeks.Changes in intestinal flora were assessed before and after six weeks in both groups.Serum markers,including HIF-1α,vascular endothelial growth factor(VEGF),interleukin-6(IL-6),and tumor necrosis factor-alpha(TNF-α),were measured using enzyme-linked immunosorbent assay.Adverse reactions,clinical efficacy,and TCM syndrome efficacy were also monitored.RESULTS:After six weeks,the levels of Lactobacillus and Bifidobacterium were significantly higher,while the levels of Enterobacter and Enterococcus were significantly lower in the TCM group compared to the control group(P<0.05).Serum levels of HIF-1α,VEGF,IL-6,and TNF-αwere also significantly reduced in the TCM group compared to the control group(P<0.05).Additionally,the incidence of adverse reactions was lower,and the clinical efficacy was higher in the TCM group compared to the control group(P<0.05).CONCLUSION:Fuzi Lizhong decoction effectively improves intestinal microbiota composition,reduces inflammatory factors and HIF-1αexpression,alleviates chemotherapy-related adverse reactions,enhances clinical efficacy,and may inhibit tumor growth in patients with colorectal cancer.

文摘OBJECTIVE:To evaluate the effectiveness and safety of the sequential therapy in treating infertility with polycystic ovary syndrome(PCOS)and luteal phase defects(LPD)by Yangxin Dianji decoction(养心奠基方,YXDJ-D)and Nuangong Tiaojing decoction(暖宫调经方,NGTJ-D).METHODS:This study was undertaken in the Jiangsu Province Hospital of Chinese Medicine.Altogether 90 eligible patients with PCOS and LPD were assigned to exposed group A(Chinese Medicine therapy,YXDJ-D and NGTJ-D),exposed group B(Chinese Medicine plus Western Medicine therapy),control group(Western Medicine therapy).The exposed group A adopted the sequential therapy that YXDJ-D is taken in the postmenstrual period(follicular phase)and NGTJ-D is taken in premenstrual period(luteal phase).Control group took letrozole,dydrogesterone and was given intramuscular injection of human menopausal gonadotropin,human chorionic gonadotropin.The exposed group B was treated with the above-mentioned therapy project of integrated Chinese Medicine and Western Medicine.This study lasted for 2 courses for 6 months.The primary outcomes were pregnancy rate and early abortion rate.The secondary outcomes were the Traditional Chinese Medicine(TCM)syndrome scores,estrogen(E2)and progesterone(P),endometrial volume(EV),vascularity index(VI),flow index(FI)and vascularization flow index(VFI).These outcomes will be assessed at baseline and post-intervention.RESULTS:The pregnancy rates of the exposed group A and B were higher than the control group(60.00%vs 60.00%vs 53.33%),while early abortion rates of exposed groups A and B were lower than the control group(33.33%vs 16.67%vs 43.75%,P>0.05).Total efficacy rates in exposed group A and B were better than the control group(93.30%vs 93.30%vs 53.30%,P<0.01).TCM symptom scores and endometrial receptivity indexes(EV,FI,VFI)were significantly lower in exposed groups compared to the control group(P<0.05).P increase in exposed group B was superior to the other two groups(P<0.01).No noticeable abnormalities in safety indicators in the three groups.CONCLUSION:The sequential therapy of YXDJ-D and NGTJ-D can effectively increase pregnancy rate,reduce the early abortion rate and alleviate the clinical symptoms of infertility in patients with PCOS and LPD by improving luteal function and promoting the endometrial receptivity.
