摘要 目的研究白虎二地汤对实验性2型糖尿病(T2DM)胰岛素抵抗大鼠血糖、血脂的影响,并探讨其机制。方法采用高糖高脂饲料喂养联合低剂量链脲佐菌素腹腔注射建立T2DM胰岛素抵抗大鼠模型,将大鼠分为正常对照组、模型组、罗格列酮组、白虎二地汤高、低剂量组。治疗前后检测空腹血糖(FBG)、空腹胰岛素(FINS)、胰岛素抵抗指数(HOMA-IR)、血清总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、游离脂肪酸(FFA)。显微镜观察五组大鼠肝脏、骨骼肌、脂肪的病理变化。结果白虎二地汤可明显降低2型糖尿病大鼠FBG、FINS、HOMA-IR及血清TC、TG、LDL-C、FFA水平,升高血清HDL-C浓度,减少肝脏组织脂肪浸润,且以高剂量白虎二地汤组效果最佳。结论白虎二地汤可以改善STZ诱导的T2DM胰岛素抵抗大鼠糖、脂代谢异常,减轻胰岛素抵抗。其可能的机制是通过降低脂毒性,增强胰岛组织对胰岛素的敏感性,发挥其改善糖脂代谢紊乱和降糖降脂作用。
