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.展开更多

文摘Pien Tze Huang(PZH),a class-1 nationally protected traditional Chinese medicine(TCM),has been used to treat liver diseases such as hepatitis;however,the effect of PZH on the progression of sepsis is unknown.Here,we reported that PZH attenuated lipopolysaccharide(LPS)-induced sepsis in mice and reduced LPS-induced production of proinflammatory cytokines in macrophages by inhibiting the activation of mitogen-activated protein kinase(MAPK)and nuclear factor-kappa B(NF-κB)signalling.Mechanistically,PZH stimulated signal transducer and activator of transcription 3(STAT3)phosphorylation to induce the expression of A20,which could inhibit the activation of NF-κB and MAPK signalling.Knockdown of the bile acid(BA)receptor G protein-coupled bile acid receptor 1(TGR5)in macrophages abolished the effects of PZH on STAT3 phosphorylation and A20 induction,as well as the LPS-induced inflammatory response,suggesting that BAs in PZH may mediate its anti-inflammatory effects by activating TGR5.Consistently,deprivation of BAs in PZH by cholestyramine resin reduced the effects of PZH on the expression of phosphorylated-STAT3 and A20,the activation of NF-κB and MAPK signalling,and the production of proinflammatory cytokines,whereas the addition of BAs to cholestyramine resin-treated PZH partially restored the inhibitory effects on the production of proinflammatory cytokines.Overall,our study identifies BAs as the effective components in PZH that activate TGR5-STAT3-A20 signalling to ameliorate LPS-induced sepsis.

文摘Objective: This paper aims to investigate the therapeutic effect of the combination of Emilia Sonchifolia and Coptidis Rhizoma on oral ulcer rats. Methods: 36 SD rats of half male and half female were kept for 7 days, and 6 rats among them were selected as normal group by random sampling method, and the rest rats were randomly divided into model group, positive control group, Emilia Sonchifolia group, Coptidis Rhizoma group and combined group after the establishment of oral ulcer model. The normal group and model group were given blank film, the positive control group was given Guilin Watermelon Frost, and the Emilia Sonchifolia group, Coptidis Rhizoma group and combined group were given the corresponding oral film, which was administered to the ulcer for 7 days continuously, 2 times per day. The healing of oral ulcer was assessed at the end of the last day of administration, and the ulcer area was calculated on the 1st, 3rd, 5th and 7th days after successful modeling, and the serum levels of IL-2 and TNF-α in rats were detected by Emilia Sonchifolia. Results: The grading of ulcer healing in the positive control group and the combined group was better than the other groups, and the difference was statistically significant when compared with the model group (p Coptidis Rhizoma group, Emilia Sonchifolia group, combined group and positive control group was smaller than that in the model group, and the difference was statistically significant (p Emilia Sonchifolia group, Coptidis Rhizoma group and combined group were all effective in reducing the area of oral ulcer, among which the combined group was more effective. The level of pro-inflammatory factor TNF-α was reduced and the level of anti-inflammatory factor IL-2 was increased in the Emilia Sonchifolia group, Coptidis Rhizoma group and combined group, and the difference was statistically significant (p Conclusion: The combination of Coptidis Rhizoma and Emilia Sonchifolia is effective in the treatment of oral ulcer in rats, and the effect of the combination is better than that of the drug alone.
文摘Huang Lian(Rhizoma coptidis, RC), which has effects on clearing damp-heat, quenching fie, and counteracting poison, is a herb frequently used in many traditional formulas. At present, there are many researches on the pharmacological effects of RC. In this review, we summarize the research progress on pharmacological effects of RC from four main aspects, in order to guide clinical application and explore the prospects of the application of RC.
文摘Background:Diethylnitrosamine,one of food additives,possessed a strong carcinogenic effect in human.Rhizoma paridis saponins,as the main active components of Paris polyphylla,have a good anti-cancer effect in our previous research.To verify their inhibitory effect on diethylnitrosamine-induced liver cancer,we carried out this study.Methods:We established diethylnitrosamine-induced mouse hepatocarcinoma models to evaluate antitumor of Rhizoma paridis saponins.Subsequently,gas chromatography-mass spectrometry was applied to analyze the metabolites in the urine and serum samples.Results:Rhizoma paridis saponins alleviated diethylnitrosamine-induced hepatocarcinogenesis.On the one hand,Rhizoma paridis saponins down-regulated the levels of liver function markers,such as alanine aminotransferase,aspartate transaminase and alpha fetoprotein.On the other hand,Rhizoma paridis saponins reduced metabolic disorders by increasing fructose and mannose metabolism,and decreasing pentose and glucuronate interconversion,inositol phosphate metabolism,and the process of saturated fatty acids transforming to unsaturated fatty acids,which based on the regulating mRNA expression of glucose transporter type 4,lactate dehydrogenase A,fatty acid synthetas,acetyl-CoA carboxylase and apolipoprotein A-I.Conclusion:Rhizoma paridis saponins has the potential application to inhibit chemical-induced hepatocarcinogenesis in the future.

文摘BACKGROUND Traditional Chinese medicine has used the drug Pien Tze Huang(PTH),a classic prescription,to treat autoimmune hepatitis(AIH).However,the precise mode of action is still unknown.AIM To investigate the mechanism of PTH in an AIH mouse model by determining the changes in gut microbiota structure and memory regulatory T(mTreg)cells functional levels.METHODS Following induction of the AIH mouse model induced by Concanavalin A(Con A),prophylactic administration of PTH was given for 10 d.The levels of mTreg cells were measured by flow cytometry,and intestinal microbiota was analyzed by 16S rRNA analysis,while western blotting was used to identify activation of the toll-like receptor(TLR)2,TLR4/nuclear factor-κB(NF-κB),and CXCL16/CXCR6 signaling pathways.RESULTS In the liver of mice with AIH,PTH relieved the pathological damage and reduced the numbers of T helper type 17 cells and interferon-γ,tumor necrosis factor-alpha,interleukin(IL)-1β,IL-2,IL-6,and IL-21 expression.Simultaneously,PTH stimulated the abundance of helpful bacteria,promoted activation of the TLR2 signal,which may enhance Treg/mTreg cells quantity to produce IL-10,and suppressed activation of the TLR4/NF-κB and CXCL16/CXCR6 signaling pathways.CONCLUSION PTH regulates intestinal microbiota balance and restores mTreg cells to alleviate experimental AIH,which is closely related to the TLR/CXCL16/CXCR6/NF-κB signaling pathway.
