摘要 目的检测肺组织中类胰蛋白酶、补体C3a的表达,初步探讨羊水栓塞(AFE)的发病机制。方法对28例尸检病例通过补体C3a与类胰蛋白酶抗原免疫组织化学染色进行回顾性研究。结果 AFE组(羊水栓塞)类胰蛋白酶表达均阳性,补体C3a表达明显下降。PHH组(高度可疑AFE病例)类胰蛋白酶阳性表达9例,补体C3a弱阳性表达7例;阴性对照组类胰蛋白酶表达弱阳性1例,补体C3a均阳性。AFE组与阴性对照组、PHH组与阴性对照组比较均有统计学差异(P<0.05)。结论类胰蛋白酶在羊水栓塞及部分产后出血病例表达,提示羊水栓塞可能与过敏反应有关,部分产后出血可能与羊水成分所激发的过敏反应有关;补体C3a表达弱阳性,提示在羊水栓塞中可能存在补体活化途径。
