【摘要】 目的:研究ER、PR及AR在内异症异位内膜、在位内膜和正常对照子宫内膜组织中的表达,阐述性激素及其受体与子宫内膜异位症发生机制的关系,探究治疗EMs的新途径。方法:利用免疫组织化学的方法检测50例EMs患者异位内膜、在位内膜及20例正常对照子宫内膜组织中ER、PR及AR的表达情况。结果:ER在EMs患者在位子宫内膜组织中的表达均明显高于异位内膜及正常对照子宫内膜,比较差异均有统计学意义(P<0.05);PR在EMs患者异位内膜组织中的表达明显低于在位内膜及正常对照子宫内膜,比较差异均有统计学意义(P<0.05);AR在EMs患者异位内膜组织中的表达明显低于在位内膜及正常对照子宫内膜,比较差异均有统计学意义(P<0.05)。结论:EMs患者异位内膜PR及AR表达的相对增高可能在内异症的发生与发展中起着一定的作用。

【Abstract】 Objective:To explore the expression of ER, PR and AR in endometriosis ectopic endometrium, eutopic endometrium and normal endometrium tissues, describe the relationship between sex hormones and their receptors, and pathogenesis of endometriosis, and explore the new ways of treatment to EMs.Method:Immunohistochemistry was used to detect the expression of ER, PR and AR of 50 cases of ectopic endometrium and eutopic endometrium of patients EMs and 20 cases of normal endometrial tissue.Result:ER expression in eutopic endometrial tissue of EMs patients were higher than the normal endometrium and ectopic endometrium of patients, the differences were statistically significant (P<0.05).PR expression in ectopic endometrium tissue in EMs patients was less than the eutopic and normal endometrium, the differences were statistically significant (P<0.05). AR expression in ectopic endometrium tissue in EMs patients was less than the eutopic and normal endometrium, the differences were statistically significant (P<0.05).Conclusion:The relatively higher expression of PR and AR in EMs patients ectopic endometrium may play a role in the occurrence and development of endometriosis.

子宫内膜异位症(EMs)是常见妇科疾患之一,其发病率有逐年增加的趋势。其发病机制不清,治疗效果不理想。子宫内膜异位症是一种雌激素依赖性疾病,其发病于育龄期,卵巢激素对它的发生发展有着重要的作用,子宫内膜作为性激素的靶器官,存在着性激素的受体,性激素与其受体结合发挥作用。本研究采用免疫组织化学的方法检测三种性激素受体在EMs患者的在位及异位内膜的表达,以探讨内异症的发病机理及激素治疗等问题。
1 资料与方法
1.1 一般资料 选取2011年6月-2013年8月在山西省妇幼保健院行手术治疗的70例患者,经过患者的知情同意,研究对象年龄在20~45岁之间。其中研究组50例为经腹腔镜检查确诊的子宫内膜异位症患者,标本为腹腔镜手术切除卵巢囊肿的囊皮及其在位子宫内膜。按美国生育协会修正(r-AFS)的分期标准,均为Ⅲ~Ⅳ期子宫内膜异位症。对照组20例为因卵巢冠囊肿或子宫中隔行手术治疗的非内异症患者,标本为患者的子宫内膜。……
