二陈汤对非酒精性脂肪肝CYP2E1及线粒体能量代谢的影响

摘要

Objective:To observe the effect of Er Chen Tang on CYP2E1 and mitochondrial energy metabolism in nonalcoholic fat-ty liver disease ( NAFLD) to explore the role of Pinellinae Rhizoma Praeparata ( PRP) and Citri reticulatae pericarpium ( CRP) in the treatment of nonalcoholic fatty liver disease. Methods:Er ChenTang and the prescription without PRP or CRP was respectively given the animal models by gastric gavage. The serum levels of ALT, AST, triglyceride, cholesterol, SOD and MDA in hepatic tissue, and the contents of liver tissue CYP2E1 and ATP were detected in the mice. Results:The CYP2E1 levels in NAFLD mice increased signif-icantly with abnormal mitochondrial energy metabolism. Compared with those in the model group, the levels of ALT, AST, triglyceride and cholesterol were significantly reduced by Er Chen Tang, meanwhile, the content of CYP2E1 was reduced and also restored liver en-ergy metabolism. The treatment effect significantly decreased when the lack of PRP or CRP, and the ability of restoring liver mitochon-drial energy metabolism of Er Chen Tang decreased significantly when the lack of PRP (P<0. 05). After the removal of CRP, the in-hibition ability of Er Chen Tang to CYP2E1 levels significantly decreased (P<0. 05). Conclusion:Er Chen Tang can effectively im-prove nonalcoholic fatty liver diseases, and effectively reduce the content of CYP2E1 in liver tissue of mice and restore the mitochondri-al energy metabolism.%目的:观察二陈汤对非酒精性脂肪肝模型小鼠肝细胞色素酶CYP2E1及线粒体能量代谢的影响,探讨二陈汤中君臣两药法半夏及陈皮在非酒精性脂肪肝治疗中的作用.方法:分别灌胃给予非酒精性脂肪肝动物模型:二陈汤及分别去除法半夏,陈皮后的二陈汤,检测小鼠血清谷氨酸转氨酶(ALT)、天门冬氨酸氨基转移酶(AST),血浆三酰甘油(TG)、总胆固醇(TC),肝脏超氧化物歧化酶(SOD)及丙二醛(MDA)水平,同时检测小鼠肝组织CYP2E1含量及三磷酸腺苷(ATP)含量.结果:脂肪肝小鼠模型CYP2E1含量明显升高,线粒体能量代谢异常.与模型组相比,二陈汤可显著改善模型鼠ALT、AST、TG、TC、SOD及MDA水平,降低CYP2E1含量,恢复肝组织能量代谢.二陈汤去除法半夏后,改善体内ALT、AST、TC水平作用,及恢复肝组织线粒体能量代谢能力均显著下降(P<0.05);二陈汤去除陈皮后,改善体内ALT、AST、TC、SOD、MDA水平的作用,以及对CYP2E1含量抑制作用则明显降低(P<0.05).结论:二陈汤有效改善非酒精性脂肪肝病变,并可有效降低非酒精性脂肪肝小鼠肝组织CYP2E1含量,恢复其线粒体能量代谢,而法半夏与陈皮发挥协同增效作用.
