Abstract： 目的:探讨大黄素、小檗碱改善非酒精性脂肪肝患者体内高瘦素水平的作用及机制.方法:用MTT法筛选大黄素、小檗碱作用于HepG2细胞实验浓度,在HepG2细胞中加入高浓度的瘦素(10-6 mol/L)作为模型组,在模型组中分别加入大黄素、小檗碱及地塞米松,并设对照组进行比较.用RT-PCR检测细胞上瘦素长型受体及短型受体mRNA的表达水平.结果:模型组细胞上瘦素长型受体及短型受体mRNA的表达水平较对照组显著下调(P<0.01),大黄素、小檗碱及地塞米松组较模型组显著上调(P<0.01),较对照组无明显改变(P>0.05).结论:大黄素和小檗碱具有通过上调瘦素受体mRNA的表达来治疗高浓度瘦素诱导机体产生非酒精性脂肪肝的作用.
