摘要 目的探讨绝经期子宫内膜息肉的发病机制。方法选取30例绝经期子宫内膜息肉患者作为实验组,选取绝经期子宫内膜正常者30例作为对照组。息肉组均进行宫腔镜下子宫内膜息肉电切术,取息肉组织为实验组一,取远离息肉的内膜组织为实验组二。经石蜡病理证实为良性子宫内膜息肉。实验组和对照组均检测外周血激素6项,将两组中雌激素进行对比,应用免疫组织化学方法测定息肉及子宫内膜中芳香化酶的表达,用Image-Pro Plus 6.0图像分析软件进行图片分析,平均光密度值为比较指标。结果实验组和对照组血清雌激素水平分别为:(16.5±2.11)pg/ml和(15.8±2.28)pg/ml,两组外周血雌激素水平差异无统计学意义;实验组一、实验组二和对照组组织中芳香化酶表达的平均光密度分别为(0.101 1±0.001 3)、(0.025 5±0.001 0)、(0.024 7±0.000 7),以α=0.05的检验水准,实验组一中芳香化酶的表达明显高于实验组二,差异有统计学意义(P<0.05);实验组二中芳香化酶的表达与对照组差异无统计学意义(P>0.05)。结论绝经期子宫内膜息肉的形成不依赖于体循环雌激素水平的升高,可能与子宫内膜局部芳香化酶过表达有关。
