摘要 目的探讨可溶性人晚期糖基化终末产物受体胞外段—IgG Fc(sRAGE-IgG Fc)融合蛋白对糖尿病(DM)大鼠的肾脏保护作用。方法将60只大鼠随机分为正常对照组、糖尿病肾病(DN)组、洛汀新组、sRAGE-IgGFc 4 mg/kg组、sRAGE-IgG Fc 6 mg/kg组、sRAGE-IgG Fc 9 mg/kg组各10只。以左肾切除、高糖、高脂饲养及注射链脲佐菌素方法 ,建立DN模型。检测各组非空腹血糖(FPG)、胰岛素(INS)、血脂、血肌酐(Scr)、尿素氮(BUN)、肌酐清除率(Ccr)、尿白蛋白排泄率(UAER)等,观察其肾组织变化。结果与DN组比较,sRAGE-IgG Fc用药组、洛汀新组的Scr、BUN、Ccr、UAER等指标均明显降低,肾脏病变不同程度地减轻(P均<0.01);除正常对照组外,其他组间FPG、INS、血脂改变无统计学意义(P均>0.05)。说明sRAGE-IgG Fc融合蛋白对DN大鼠的肾脏保护作用具有剂量依赖性。结论 sRAGE-IgG Fc融合蛋白对DN大鼠的肾脏有明显保护作用,其功能与洛丁新相当。
