摘要
目的 了解绝经期及子宫腺肌症患者雌、孕激素受体(estrogen receptor,ER;progesterone receptor,PR)在子宫全层中的表达。方法 选择因子宫脱垂行阴式子宫全切的绝经期患者及子宫腺肌症患者行子宫全切术,分别取子宫体的全层组织,用免疫组织化学的方法研究不同病症中ER、PR在子宫全层(内膜层、浅肌层、深肌层及浆膜层)中的表达情况,采用图像分析仪和光学显微镜进行测定,对ER、PR阳性细胞的表达率进行比较。结果 绝经期ER、PR在子宫内膜层中高度表达,与其他各层比较差异有统计学意义(P<0.01),浆膜层含量最少,亦与其他各层有统计学差异(P<0.01),浅肌层、深肌层之间无统计学差异(P=0.148)。子宫腺肌症患者中子宫浆膜层ER、PR受体含量最少,与其他各层有统计学差异(P<0.01),子宫内膜层、浅肌层、深肌层之间无统计学差异。结论 绝经期由于雌孕激素水平急剧下降,子宫各层中ER、PR含量较低,但在子宫内膜中仍占多数。ER、PR在子宫腺肌症患者子宫内膜层表达无显著性差异。因此保留子宫的经宫颈子宫内膜电切术治疗子宫腺肌症可能疗效不佳。
Abstract
Objective To compare the gradient distribution of estrogen and progesterone receptor in the whole layers of the uterus (mucous, superficial myometrium, deep myometrium layer and subserious layers) by the expression of estrogen and progesterone receptors. Methods To evaluate the distribution and intensity of estrogen receptor (ER) and progesterone receptor (PR) stained in the various part of human endometrium and myometrium, two different diseases were chosen in the menopause and adenomyosis group. Immuno-histochemical study was performed on ER and PR in the whole layers (mucous layer, superficial myometrium layer, and deep myometrium layer). Results There was significant difference in distribution of ER and PR between endometrium and other layers (P<0.01) in menopause group. There was significant difference in distribution of ER and PR between subserous and other layers (P=0.000) in adenomyosis group. Conclusions In menopause ER and PR levels is maximum in the endometrium. So the endometrial abalation is effective for the tamoxifen-treated breast cancer patients.
