Abstract

目的 探讨黄芪-黄连药对可能通过Keap1/Nrf2/GPX4通路来降低糖耐量减低大鼠(IGT)肝脏脂肪沉积的潜在作用机制。 方法 SPF级雄性Wistar大鼠,随机挑选10只作为空白组,余给予高糖高脂饮食10周和小剂量链脲佐菌素复制IGT模型,分为模型组(n=9)、黄芪-黄连药对组(4.05 g·kg-1·d-1,n=10)、二甲双胍组(0.05 g·kg-1·d-1,n=9)。干预4周,观察各组一般情况、血糖相关指标改变;HE染色观察肝脏组织形态;免疫荧光染色与qPCR检测肝脏组织Keap1、Nrf2、HO-1、GPX4蛋白、mRNA含量。 结果 干预后,黄芪-黄连可降低OGTT试验2h血糖(P
