摘要 目的:观察糖尿病肾病(DN)大鼠肾组织中α-平滑肌肌动蛋白(α-SMA)分布及含量的变化,探讨内源性H2S在糖尿病肾病病理变化中的作用。方法:雄性SD大鼠28只随机分为:对照组、DN组、H2S干预组、胱硫醚-γ-裂解酶(CSE)阻断剂组。采用免疫组织化学法及Western免疫印迹法,检测各组大鼠肾脏组织中α-SMA的分布及含量。结果:(1)对照组大鼠肾脏中的α-SMA主要存在于血管壁,DN组、CSE阻断剂组除血管壁外,肾小球系膜区及肾间质均有表达;H2S干预组的DN大鼠肾脏中α-SMA的表达与对照组相似,主要位于血管壁。(2)与对照组比较,DN组中α-SMA的含量增加[DN组(40209±935)vs对照组(16028±958),P<0.01];与DN组及CSE阻断剂组比较,H2S干预组中α-SMA的含量下降[H2S干预组(23612±510)vsDN组(40209±935)、CSE阻断剂组(39338±1342),P<0.01]。结论:内源性H2S可抑制DN大鼠肾脏中成肌纤维细胞的生成,延缓糖尿病肾病的病理改变。
