摘要：

目的探究大黄酚(chrysophanol,CP)对幼龄大鼠非酒精性脂肪肝(non-alcoholic fatty liver disease,NAFLD)的调节作用。方法将40只大鼠随机分为对照(control,Ctrl)组、CP组,高脂(high-fat,HF)组和HF+CP组。HF组和HF+CP组用高脂饲料喂养,其余2组以正常饲料喂养,CP组和HF+CP组同时腹腔注射CP(30 mg/kg)。4周后收集各组大鼠血清及肝脏组织,HE染色检测肝脏病理情况、TUNEL法检测细胞凋亡、Western blot检测脂质合成和分解代谢基因的表达、ELISA检测血清炎症因子水平。结果与Ctrl组比较,HF组大鼠肝脏组织出现明显的肝脂肪变性及炎性细胞浸润,凋亡小体明显增多;与HF组比较,HF+CP组大鼠肝组织脂肪变性及炎性细胞浸润显著减轻,凋亡小体数明显减少;同时,与Ctrl组比较,HF组大鼠脂质合成代谢基因ACC和SPEBP-1c的表达水平明显升高,分解代谢基因PPARα和CPT-1的表达水平明显降低,CP能显著减弱HP对ACC、SPEBP-1c、PPARα和CPT-1表达的影响。此外,HF能显著升高大鼠血清IL-1β和IL-6水平,CP能显著降低模型大鼠血清IL-1β和IL-6水平。结论 CP能通过调控脂质的合成代谢及炎症反应减轻幼龄大鼠NAFLD。
