摘要 目的 观察白藜芦醇对代谢综合征(MS)大鼠糖脂代谢的改善作用.方法 采用高脂高盐高糖饮食诱导大鼠MS模型,随机分为正常组、模型组、白藜芦醇组(100 mg/kg)、二甲双胍组(150 mg/kg),灌胃给药4周.观察一般行为学,记录体质量和血压,计算体脂比;检测FPG、FINS,计算胰岛素抵抗指数(HOMA-IR);检测TC、TG、LDL-C、HDL-C)水平;qRT-PCR法检测AMPKα、ChREBP、SREBP-1 mRNA表达;Western blot法检测肝脏乙酰ACCα、Fas蛋白表达.结果 与模型组比较,白藜芦醇能有效控制MS大鼠体质量增长、腹腔脂肪蓄积(P<0.05),降低体脂比、SBP、DBP、FPG、FINS、HOMA-IR(P<0.05,P<0.01),降低LDL-C水平(P<0.05),增加HDL-C水平(P<0.05),促进AMPKα mRNA表达(P<0.05),同时下调ChREBP、SREBP-1 mRNA (P<0.01)及ACCα、Fas蛋白表达(P<0.01).结论 白藜芦醇通过调节AMPK及相关靶分子活性改善糖脂代谢,这可能是其有效防治MS的重要机制.
