- Abstract: Aim To examine the therapeutic effects of DHZCP on carbon tetrachloride(CCl4)-induced chemical hepatic fibrosis model in rats and the mechanism of acid-sensitive ion channels 1a(ASIC1a)and vascular endothelial growth factor(VEGF)-related mechanisms.Methods The rats were injected intraperitoneally with CCl4 vegetable oil mixture to establish hepatic fibrosis model,and randomly divided into six groups:control group,hepatic fibrosis model group,DHZCP low dose group,DHZCP medium dose group,DHZCP high dose group and colchicine(Col)positive control group.HE staining was used to observe the pathological changes of hepatic structures in each group,Masson staining to view the production of collagen fibers in each group,and immunohistochemistry,Western blot,q-PCR to investigate the expression level of ASIC1a,CaMKKβ,VEGF,α-SMA,Collagen-I proteins.Results In model group,serum ALT and AST levels were obviously up-regulated,liver tissue structure was severely damaged,and ASIC1a,CaMKKβ,VEGF,α-SMA,Collagen-I gene and protein expression levels were significantly elevated.Compared with model group,each treatment group of DHZCP could markedly alleviate the pathological changes of liver fibrosis caused by CCl4,significantly reduce the serum ALT and AST levels,and dose-dependently down-regulate the gene and protein expression levels of ASIC1a,CaMKKβ,VEGF,α-SMA,Collagen-I,etc.Conclusions DHZCP ameliorates hepatic fibrosis in rats,and its mechanism of action may be associated with the regulation of ASIC1a/VEGF.
