摘要(Abstract)：

目的:观察解偶联蛋白2(UCP2)在高脂饮食诱导的非酒精性脂肪性肝炎(NASH)大鼠肝组织的表达及山楂叶总黄酮(TFHL)对其的影响。方法:以高脂饮食喂养12周诱导SD大鼠建立NASH模型,同时分别以250,125 mg.kg-1.d-1的TFHL和195.4 mg.kg-1.d-1的易善复进行干预,观察大鼠肝组织的病理改变,血清ALT,AST水平,肝组织匀浆TG,CHOL,MDA含量和T-AOC的活性,RT-PCR检测UCP2基因mRNA在肝组织中表达,ELISA检测肝组织UCP2含量。结果:NASH模型组大鼠肝组织重度脂肪变、炎细胞浸润,血清ALT,AST水平和肝组织TG,CHOL,MDA,UCP2含量较正常大鼠明显增高,UCP2 mRNA表达显著增强,T-AOC活性明显降低。肝组织UCP基因的表达与MDA含量呈明显正相关,与T-AOC活性则呈负相关。TFHL高、低剂量组大鼠肝组织炎症活动程度、肝匀浆MDA和UCP2含量以及肝组织UCP2 mRNA表达均较模型组大鼠显著降低,而肝匀浆T-AOC的活性则较模型组大鼠明显增高。结论:TFHL可能是通过抑制氧应激/脂质过氧化反应和肝组织UCP2过表达的途径减轻肝脏炎症损伤,从而防止NASH的进一步发展。
