摘要 目的观察糖原合成激酶-3β(GSK3β)抑制剂对糖尿病肾病大鼠的肾脏保护作用,探讨其可能机制。方法将实验大鼠随机分为正常对照组(NC组)、GSK3β抑制剂(CI)、糖尿病模型组(DM组)和糖尿病GSK3β抑制剂治疗组(DI)。糖尿病大鼠GSK3β抑制剂治疗组干预治疗后,处死大鼠,检测24 h尿蛋白、血清肌酐(Scr);肾脏组织切片行PAS染色,观察大鼠肾脏病理改变;用免疫组化(IHC)方法检测结缔组织生长因子(CTGF)在肾脏中的表达,测量血清中细胞间黏附分子(ICAM)-1含量。结果 GSK3β抑制剂可以减轻糖尿病大鼠肾脏病理功能改变。与NC组相比,DM组大鼠CTGF蛋白表达增强(均P<0.01);血清中ICAM-1水平升高(均P<0.01)。与DM组相比,DI组大鼠CTGF蛋白表达下降(均P<0.01);血清中ICAM-1水平下降(均P<0.01)。结论 GSK3β抑制剂可以通过抑制糖尿病大鼠肾脏纤维化,降低结缔组织生长因子(CTGF)表达,减轻糖尿病大鼠肾脏病理改变。通过抑制炎症反应,降低血清中ICAM-1含量,发挥肾脏保护作用。
