Abstract:
Objective To observe the effects of Jianpi Liqi Huashi Prescription on hepatocyte injury,oxidative stress and nitrative stress in mice with non-alcoholic steatohepatitis(NASH);To explore its mechanism in the treatment of NASH.Methods Totally 32 male C57BL/6J mice were randomly divided into control group,model group and TCM low-and high-dosage groups,with 8 mice in each group.The control group was fed with ordinary diet,and the other groups were fed with high-fat diet,for consecutive 16 weeks.Starting from the 13th week,the control group and model group were given 0.4%CMC-Na solution by intragastric administration and the TCM groups were given corresponding doses of drugs by intragastric administration,respectively.Biochemical instrument was used to detect serum alanine aminotransferase(ALT)and aspartate aminotransferase(AST)contents,HE staining and oil red O staining were used to detect liver histopathology,triglyceride(TG)content and myeloperoxidase(MPO)activity in liver tissue were detected through test kit.immunofluorescence staining was used to detect positive expression of CD11b in liver tissue,the mRNA expressions of NOX1 and NCF1 were detected by RT-PCR,and the protein expressions of inducible nitric oxide synthase(iNOS)and 3-nitrotyrosine(3-NT)in liver tissue were detected by Western blot.Results Compared with the control group,the hepatocytes in the model group showed diffuse steatosis,hepatocyte swelling and inflammatory cell infiltration;a large number of fat droplets were formed by oil red O staining;serum ALT and AST contents significantly increased(P<0.05),the TG content and MPO activity in liver tissue significantly increased(P<0.05);the positive expression of CD11b in liver tissue increased;the mRNA expressions of NOX1 and NCF1 in liver tissue significantly increased(P<0.05);the expressions of iNOS and 3-NT protein in liver tissue significantly increased(P<0.05).Compared with the model group,the degree of liver steatosis,the level of inflammatory cell infiltration and the number of lipid droplets in TCM groups decreased significantly;serum ALT and AST contents significantly decreased(P<0.05);the TG contents and MPO activity in liver tissue significantly decreased(P<0.05);the positive expression of CD11b in liver tissue decreased;the mRNA expressions of NOX1 and NCF1 in liver tissue significantly decreased(P<0.05);the expression of 3-NT protein in liver tissue significantly decreased(P<0.05);the expression of iNOS protein in liver tissue of mice in TCM high-dosage group significantly decreased(P<0.05).Conclusion Jianpi Liqi Huashi Prescription may relieve liver cell damage,lipid deposition and inflammation in NASH mice by alleviating oxidative stress and nitrative stress in the liver,and play a role in the treatment of NASH.
