Abstract:
Objective::To investigate the protective effect of modified Yinchenhao Tang on α-isothiocyanate(ANIT)-induced cholestatic liver disease (CSLD). Method::Wistar rats were randomly divided into 7 groups: blank control group, model control group, compound Glycyrrhizin capsules group(22.5, 45 mg·kg-1), modified Yinchenhao Tang low, middle and high dose groups(4.1, 8.1, 16.2 g·kg-1). A model of cholestatic liver injury was prepared by intragastric administration of ANIT (100 mg·kg-1). Glycyrrhizin capsules and modified Yinchenhao Tang were administered intragastrically on the second day of modeling for 4 consecutive days. And bile duct intubation was performed on the fifth day to measure the bile flow rate of the rats, and serum was taken to test the total bilirubin(TBIL), direct bilirubin(DBIL), indirect bilirubin(IBIL), alanine aminotransferase(ALT) and total bile acid(TBA) serological indicators of each group. Pathological changes of liver tissues were observed by hematoxylin-eosin (HE) staining. The expression levels of G protein-coupled bile acid receptor(TGR5), nucleotide binding oligomerization domain-like receptor 3(NLRP3) and cysteinyl aspartate specific proteinase-1(Caspase-1) proteins in the iver tissues were detected by Western blot. Result::Compared with the blank control group, bile flow rate in the model group decreased significantly(P<0.01). TBIL, DBIL, IBIL, ALT and TBA level in serum were significantly increased(P<0.01), liver tissue lesions were severe, and significantly increased the expression of liver tissue TGR5 and Caspase-1.Compare with model group, the compound Glycyrrhizin capsules group had no significant effect on bile flow rate and TBIL, DBIL, IBIL, ALT and TBA level in serum. Bile flow rate increased and TBIL, DBIL, IBIL, ALT and TBA level in serum decreased significantly in modified Yinchenhao Tang high dose group. The compound Glycyrrhizin capsules group and modified Yinchenhao Tang group have different extents of improvement the pathological changes of the lung tissues, and the protein expression of TGR5 and Caspase-1 were significantly decreased in the liver tissue(P<0.01). Conclusion::Modified Yinchenhao Tang can effectively treat CSLD in rats, and its mechanism may be related to bile acid and bile acid receptor TGR5-mediated inflammatory factors.
