选择3种典型的寒性中药大黄、黄芩和黄连,以及3种典型的热性中药肉桂、干姜及附子,在小鼠中观察上述6种代表性寒热中药对动物机体代谢的调节作用,重点观察了短期(7 d)及长期(35 d)干预对动物脂质代谢及能量代谢的作用。采用real-time PC... 选择3种典型的寒性中药大黄、黄芩和黄连,以及3种典型的热性中药肉桂、干姜及附子,在小鼠中观察上述6种代表性寒热中药对动物机体代谢的调节作用,重点观察了短期(7 d)及长期(35 d)干预对动物脂质代谢及能量代谢的作用。采用real-time PCR法测定附睾脂肪组织和肝脏中脂质代谢基因mRNA表达水平;通过代谢系统检测机体耗氧量、二氧化碳生成量、热量消耗等。在短期干预下,热性中药显著降低脂肪组织指数,升高肝脏和附睾脂肪组织中乙酰辅酶A羧化酶(ACC)、脂蛋白酯酶(LPL)、肉碱-棕榈酰转移酶1(CPT-1)表达量;寒性中药促进附睾脂肪组织以上基因表达。在长期干预下,寒热中药对动物附睾脂肪指数均无明显影响,而寒性中药干预可以增加机体二氧化碳生成量和热量消耗,以及降低活动量。该研究表明短期寒热中药干预对动物机体代谢的影响明显强于长期干预,表现为短期干预寒性中药可促进附睾脂肪组织脂质代谢,热性中药可促进附睾脂肪组织和肝脏脂质代谢。长期寒热中药干预对机体脂质水平几乎没有明显影响,不过,长期寒性中药干预可促进机体能量消耗。该研究初步从机体脂质及能量代谢的角度观察了寒热属性中药对正常动物生理的影响,为基于生物体响应解释寒热属性中药的生物学基础提供参考。 展开更多

Cholestasis is caused by the obstacle of bile formation or secretion and can develop into severe liver diseases. We previously reported the ethanol extract of Schisandra sphenanthera(Wuzhi tablet, WZ) can significantly protect against lithocholic acid(LCA)-induced intrahepatic cholestasis in mice, partially due to the activation of PXR pathway and promotion of liver regeneration.However, the effect of WZ on the bile acids profile and gut microbiome in cholestastic mice remain unknown. In this study, the effect of WZ against LCA-induced liver injury was evaluated and its effect on the bile acids metabolome and gut microbiome profiles in cholestastic mice was further investigated. Targeted metabolomics analysis was performed to examine the change of bile acids in the serum, liver, intestine and feces. The change of intestinal flora were detected by the genomics method. Targeted metabolomics analysis revealed that WZ enhanced the excretion of bile acids from serum and liver to intestine and feces. Genomics analysis of gut microbiome showed that WZ can reverse LCA-induced gut microbiome disorder to the normal level. In conclusion, WZ protects against LCAinduced cholestastic liver injury by reversing abnormal bile acids profiles and alteration of gut microbiome. 展开更多

Huang-Qin Decoction(HQD)is a classic prescription for diarrhea in Chinese medicine treatment.Recent studies have demonstrated that HQD and its modified formulation PHY906 could ameliorate irinotecan(CPT-11)induced gastrointestinal(GI)toxicity and enhance its anticancer therapeutic efficacy.Nevertheless,which constituents in HQD are effective is still unclear so far.The study aims to screen out the key bioactive components combination from HQD that could enhance the anticancer effect of CPT-11.First,the potential bioactive constituents were obtained through system pharmacology strategy.Then the bioactivity of each constituent was investigated synthetically from the aspects of NCM460 cell migration,TNF-αrelease of THP-1-derived macrophage and MTT assay in HCT116 cell.The contribution of each constituent in HQD was evaluated using the bioactive index Ei,which taken the content and bioactivity into comprehensive consideration.And then,the most contributing constituents were selected out to form a keycomponent combination.At last,the bioefficacy of the key-component combination was validated in vitro and in vivo.As a result,a key-component combination(HB4)consisting of four compounds baicalin,baicalein,glycyrrhizic acid and wogonin was screened out.In vitro assessment indicated that HB4 could enhance the effect of CPT-11 on inhibiting cell proliferation and inducing apoptosis in HCT116.Furthermore,the in vivo study confirmed that HB4 and HQD have similar pharmacological activity and could both enhance the antitumor effect of CPT-11 in HCT116 xenograft model.Meanwhile,HB4 could also reduce the CPT-11 induced GI toxicity. 展开更多
