摘要
目的探讨一氧化氮合酶(NOS)在子宫内膜异位症(内异症)不孕患者在位子宫内膜(在位内膜)中的表达及促性腺激素释放激素激动剂(GnRHa)对其表达的影响。方法采用免疫组化方法及蛋白印迹方法,对30例Ⅲ~Ⅳ期内异症不孕患者(内异症组)及19例有正常生育史的宫颈原位癌患者(对照组)的在位内膜进行内皮型NOS(eNOS)及诱生型NOS(iNOS)表达的定位及半定量检测,内异症组中18例行GnRHa治疗(治疗组);采用电化学发光法,同时测定患者血清雌二醇及孕酮水平。结果eNOS在子宫内膜的腺上皮、腔上皮及血管内皮细胞中均有表达;iNOS仅在子宫内膜的腺上皮和间质细胞中微弱表达。eNOS在增生期早、中、晚期和分泌期早、中、晚期在位内膜中的相对表达水平,内异症组分别为0.30±0.04,0.40±0.03,0.49±0.03,0.43±0.04,0.55±0.04和0.48±0.03,治疗组分别为0.22±0.03,0.37±0.03,0.45±0.04,0.35±0.05,0.50±0.03和0.41±0.00,对照组分别为0.21±0.03,0.33±0.03,0.45±0.04,0.40±0.03,0.47±0.05和0.41±0.03。在整个月经周期中,内异症组患者在位内膜eNOS相对表达水平持续性高于对照组患者,但仅在增生期早、中期及分泌期中、晚期两组比较,差异有统计学意义(P<0.05);与内异症组比较,治疗组在位内膜eNOS相对表达水平均有所下降,但仅在增生期早期及分泌期早、中期比较,差异有统计学意义(P<0.05)。3组子宫内膜中均未检出iNOS的表达。血清雌二醇或孕酮水平与子宫内膜eNOS表达水平均呈正相关(P<0.01)。结论eNOS在内异症患者在位内膜中的高表达,可能与其发病及其所致的不孕有关,GnRHa治疗可降低内异症患者在位内膜eNOS的表达。
