- Abstract
Objective: To study the prevention and treatment mechanism of Qingxia therapy (based on Yinchenhao Decoction and Dachengqi Decoction) on hepatocyte apoptosis in rats with acute hepatic injury induced by lipopolysaccharide plus D-galactosamine (LPS/D-GalN)., Methods: The acute hepatic injury model was established by LPS/D-GalN and then intervened with Qingxia therapy. Serum liver function, PT and liver tissue pathology were observed, hepatocyte apoptosis index was detected by Tunel, protein expressions of BCL-2, BAX and Caspase-3 were detected by Western blotting., Results: Qingxia therapy could significantly decrease serum ALT, AST and TBIL levels (P < 0.01 or 0.05), reduce hepatocyte necrosis and inflammatory cell infiltration. There were more apoptotic cells in model group, which had significant differences compared with Qingxia group and control group. Protein expressions of BAX and Caspase-3 in model group were significantly higher than those in control group and Qingxia group (P < 0.05), but BCL-2 protein expression in model group was lower (P < 0.05)., Conclusion: Qingxia therapy can ameliorate the liver function and hepatic tissue pathology of rats with hepatic injury induced by LPS/D-GalN, alleviate hepatocyte apoptosis in rats, prevent and treat hepatocyte apoptosis by down-regulating the protein expressions of Caspase-3 and BAX, up-regulating the protein expression of BCL-2, and adjusting the balance of BCL-2/BAX.
