Colorectal cancer (CRC) is one of the most common and deadly cancers in the world and is a typical inflammatory tumor. In recent years, the incidence of CRC has been increasing year by year. There is evidence that the intake of high-fat diet and overweight are associated with the incidence of CRC, among which bile acids play a key role in the pathogenesis of the disease. Studies on the relationship between bile acid metabolism and the occurrence of CRC have gradually become a hot topic, improving the understanding of metabolic factors in the etiology of colorectal cancer. Meanwhile, intestinal flora also plays an important role in the occurrence and development of CRC In this review, the classification of bile acids and their role in promoting the occurrence of CRC are discussed, and we highlights how a high-fat diet affects bile acid metabolism and destroys the integrity of the intestinal barrier and the effects of gut bacteria.

Immune injury is the main side effect caused by cyclophosphamide and the disruption of the intestinal barrier may be an important cause. Yupingfeng granules have been reported to have immunomodulatory effects and polysaccharides are important components of them. This study aimed to investigate the ameliorative effect of polysaccharides from Yupingfeng granules (YPFP) on cyclophosphamide induced immune injury and reveal their potential mechanisms based on its protective effect on the intestine.

Bile acids (BAs), not only promote the absorption of fat-soluble nutrients and regulate the metabolism of multiple substances but also have a potential role as diagnostic and prognostic indicators in a variety of diseases such as cholestasis, hepatocellular carcinoma, and diabetes mellitus. Here, a rapid and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the simultaneous quantification of 50 BAs was developed and validated. Sample preparation included internal standard spiking, followed by protein precipitation, centrifugation, solvent evaporation, and reconstitution.

Background And Aims: Alcohol abuse is the most frequent precipitating factor of acute-on-chronic liver failure (ACLF). We aimed at developing an alcohol-induced ACLF model and dissecting its underlying molecular mechanisms.
Methods: ACLF was triggered by a single alcohol binge (5g/Kg) in a bile duct ligation (BDL) liver fibrosis murine model.

Background: Yes-associated protein 1 (YAP1) regulates the survival, proliferation, and stemness of cells, and contributes to the development of metabolic dysfunction associated fatty liver disease (MAFLD). However, the regulatory role of intestinal YAP1 in MAFLD still remains unclear.
Methods: Terminal ileal specimens were used to compare intestinal YAP1 activation in patients with and without MAFLD.
