However, the emerging evidences in the past decade showed that BAs act as signaling molecules that not only autoregulate their own metabolism and enterohepatic recirculation, but also as important regulators of integrative metabolism by activating nuclear and membrane-bound G protein-coupled receptors. The present review was to get insight into the role of maintenance of BA homeostasis and BA signaling pathways in development and management of hepatobiliary and intestinal diseases.DATA SOURCES: Detailed and comprehensive search of PubM ed and Scopus databases was carried out for original and review articles.RESULTS: Disturbances in BA homeostasis contribute to the development of several hepatobiliary and intestinal disorders, such as non-alcoholic fatty liver disease, liver cirrhosis, cholesterol gallstone disease, intestinal diseases and both hepatocellular and colorectal carcinoma.CONCLUSION: Further efforts made in order to advance the understanding of sophisticated BA signaling network may be promising in developing novel therapeutic strategies related not only to hepatobiliary and gastrointestinal but also systemic diseases.展开更多

In order to understand the complex interplay between HBV and hepatic metabolism in greater depth, we systematically reviewed these alterations in different metabolic signaling pathways due to HBV infection. HBV infection interfered with most aspects of hepatic metabolic responses, including glucose, lipid, nucleic acid, bile acid and vitamin metabolism. Glucose and lipid metabolism is a particular focus due to the significant promotion of gluconeogenesis, glucose aerobic oxidation, the pentose phosphate pathway, fatty acid synthesis or oxidation, phospholipid and cholesterol biosynthesis affected by HBV. These altered metabolic pathways are involved in the pathological process of not only hepatitis B, but also metabolic disorders, increasing the occurrence of complications, such as hepatocellular carcinoma and liver steatosis. Thus, a clearer understanding of the hepatic metabolic pathways affected by HBV and its pathogenesis is necessary to develop more novel therapeutic strategies targeting viral eradication.展开更多
为探究茯砖茶水提物(Fuzhuan brick tea water extract,FTE)预防肥胖及高胆固醇血症的作用机制,本实验以SPF级SD大鼠为研究对象,设置了正常饮食组、高脂饮食组以及不同剂量FTE干预组,采用降脂药物血脂康作为阳性对照组,对比茯砖茶在预...为探究茯砖茶水提物(Fuzhuan brick tea water extract,FTE)预防肥胖及高胆固醇血症的作用机制,本实验以SPF级SD大鼠为研究对象,设置了正常饮食组、高脂饮食组以及不同剂量FTE干预组,采用降脂药物血脂康作为阳性对照组,对比茯砖茶在预防肥胖型血脂异常的效果。结果表明,FTE能通过调节大鼠肠道微生物群结构和功能,影响肠-肝胆汁酸(bile acid,BA)代谢循环,增强机体抗氧化作用,促进全身性脂质消耗,并对肝脏与肠道的结构和功能具有明显保护作用,同时改善脂质谱与炎症反应,抑制高脂饮食环境下大鼠体质量的过快增长。综上,FTE能够对营养型肥胖以及高胆固醇血症具有显著预防作用,在预防体质量增长和脂质积累、增加脂质消耗、抑制肝功能酶活性以及调节胆汁酸代谢方面比降脂药物血脂康具有优势。展开更多
