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Background:Baitouweng decoction is a classic prescription for treating chronic dysentery and mainly used to treat heat-toxic dysentery and is widely used in damp-heat ulcerative colitis(UC)in China.Methods:Meta-analysis and network pharmacology were used to examine the pharmacological properties of Baitouweng decoction in the treatment of UC.Additionally,the potential mechanisms of action were investigated.In the meta-analysis,studies were searched from databases up to March 2024.Data from the included studies were extracted.The results were quantified by calculating the standardized mean difference(SMD).Additionally,95%confidence intervals(CI)were used to assess the precision of the estimates.Results:It was found that 201 components of Baitouweng decoction,including Pulsatillae Radix(Baitouweng),Coptidis Rhizoma(Huanglian),Phellodendri Chinensis Cortex(Huangbo),Fraxini Cortex(Qinpi),and 106 intersecting targets of UC,were obtained from INPUT.PPI and enrichment analyses showed Baitouweng decoction might regulate inflammatory response to improve UC injury.Seventeen included studies were published between 2004 and 2024.The meta-analysis results suggested that Baitouweng decoction may help increase body weight,decrease DAI and CMDI,reduce colon length shortening associated with UC,lower the spleen index,and alleviate tissue damage in colitis.In addition,Baitouweng decoction could inhibit inflammatory response and repair intestinal barrier in UC model.The protective mechanism of Baitouweng decoction was consistent with the predicted targets of network pharmacology,which suggested the results were accurate.Conclusion:Baitouweng decoction could improve UC injury by regulating the inflammatory response,cell apoptosis,and body metabolism through the integration of network pharmacology and meta-analysis.Its protective mechanisms are related to anti-inflammation,regulation of intestinal flora,brain-gut peptides,and protection of the intestinal mucosal barrier,along with modulation of body metabolism,including SCFA,bile acids,and tryptophan metabolism.

文摘Hypertension is one of the most prevalent cardiovascular diseases,and autophagy is known to play a significant role in the pathogenesis and progression of cardiovascular conditions.This study aimed to evaluate the effects of Huanglian Jiedu decoction(HLJDD)on myocardial mitochondrial autophagy in spontaneously hypertensive rats(SHRs)and to further explore the relationship between autophagy,myocardial remodeling,and injury.The SHRs were randomly assigned to five groups:the model group,the HLJDD low-dose group,the HLJDD medium-dose group,the HLJDD high-dose group,and a positive control group treated with captopril.Additionally,a blank control group was established using Wistar Kyoto(WKY)rats,with 10 rats in each group.The model and blank control groups were administered an equivalent volume of physiological saline via oral gavage,while the treatment groups received their respective doses of HLJDD or captopril by oral gavage.Following the treatments,various parameters were assessed,including blood pressure(systolic,diastolic,and mean arterial pressure),mitochondrial swelling and membrane potential,free ATPase activity,as well as the mRNA and protein levels of autophagy-related factors.The results showed that HLJDD significantly reduced blood pressure(systolic,diastolic,and mean arterial pressure)in SHR rats.Moreover,it enhanced mitochondrial swelling and membrane potential,increased mitochondrial ATPase activity,and decreased the mRNA and protein expression levels of autophagy-related genes(AKT,mTOR,Beclin-1,and LC3-II)in SHRs.The findings of this study suggested that HLJDD could effectively ameliorate myocardial tissue injury in SHRs,and its protective effects on the heart might be attributed to the reduction of autophagy in cardiomyocyte mitochondria.This provided insights into the potential therapeutic use of HLJDD in managing hypertension-induced myocardial injury and remodeling.

文摘Background:The traditional Chinese medicine compound Sancao decoction(SCD)is a folk prescription for regulating immunity.It is composed of 8 Chinese herbal medicines,such as Prunellae Spica(Xiakucao),Houttuyniae Herba(Yuxingcao),Lysimachiae Herba(Jinqiancao)and so on.In cancer,the interleukin-6(IL-6)/the signal transducer and the activator of transcription 3(STAT3)pathway directly promotes the proliferation,survival and angiogenesis of cancer cells,and arginase-1(ARG-1)is a key enzyme for myeloid-derived suppressor cells(MDSCs)to exert immunosuppressive function.It is not clear whether SCD regulates the expression of ARG-1 in MDSCs through the IL-6/STAT3 pathway.Therefore,we explored the effect and mechanism of SCD on lung metastasis of breast cancer.Methods:The components in SCD have been analyzed by HPLC-MS.A spontaneous metastasis model of breast cancer was established by injecting 4T1 cells into the mammary fat pad of BALB/c mice.Pre-metastatic niche(PMN)formation and the role of SCD on PMN were evaluated by lung metastasis nodules,lung pathology tests and immunofluorescence for 2–4 weeks.Serum tests and hematoxylin-eosin staining(H&E)were used to evaluate the side effects of cisplatin.Western blot and ELISA were used to detect proteins and cytokines of the STAT3 signaling pathway in mouse lung tissue.Results:Compared with SCD or cisplatin treatment alone,SCD/cisplatin(CP)synergistic administration not only significantly inhibited orthotropic breast tumor growth,but also reduced lung metastasis and alleviated the hepatorenal toxicity induced by CP in vivo.Remarkably,the combination effectively inhibited PMN formation and the accumulation of MDSCs in the lung PMN,accompanied by the significant infiltration of CD4+T and CD8+T-lymphocytes in the lung PMN and spleen.In addition,the SCD/CP combination downregulated protein expression levels of STAT3,p-STAT3,IL-6 and ARG-1 in the lung PMN of breast cancer mice.Conclusion:The synergistic effect of SCD and cisplatin inhibited MDSCs aggregation and the immunosuppressive function of pulmonary PMN,thereby remodeling the immunosuppressive tumor microenvironment and enhancing anti-tumor immunity,leading to remission of orthotopic breast cancer and lung metastases and amelioration of cisplatin-induced liver and kidney toxicity.
