摘要：

目的:研究子宫内膜异位症(内异症)患者在位内膜神经生长因子(NGF)及其受体trkA、p75NTR的表达,探讨上述因子与内异症疼痛的关系。方法:选择就诊于北京协和医院并进行了腹腔镜手术的28例子宫内膜异位症患者作为研究组,非子宫内膜异位症患者10例作为对照组(B组),收集上述患者分泌期在位子宫内膜。根据患者有无痛经,分为内异症疼痛组(A1组,18例)及内异症非疼痛组(A2组,10例)。采用免疫组化比较各组病灶中NGF及其受体trkA、p75NTR的表达,并分析其与痛经的关系。结果:各组在位内膜腺上皮中NGF的表达显著高于间质(P<0.05);内异症疼痛组腺上皮NGF表达较非疼痛组明显升高(359.9±18.7 vs 201.3±34.3,P<0.05)。p75NTR主要在子宫内膜间质细胞中表达;内异症组明显高于非内异症组(58.8±21.1、22.5±16.1 vs 0,P<0.05);内异症疼痛组较非疼痛组p75NTR表达明显升高(58.8±21.1 vs 22.5±16.1,P<0.05)。trkA在非内异症组子宫内膜间质中表达明显高于腺上皮(P<0.05);在内异症组腺上皮中,trkA的表达较非内异症组明显增高(P<0.05);trkA的表达量与内异症患者疼痛无关。结论:p75NTR可能参与内异症的发病,NGF及其受体p75NTR在在位内膜中的表达与患者疼痛相关,表明其可能参与了内异症疼痛发病机制。
