类固醇生成因子1在卵巢子宫内膜异位囊肿及子宫腺肌病病灶中的表达

目的 探讨类固醇生成因子1( SF-1)在子宫内膜异位症(内异症)患者在位内膜、卵巢内异症囊肿、子宫腺肌病病灶中的表达.方法 选择2008年1月至2010年12月在北京大学第一医院妇科住院,因子宫腺肌病合并卵巢内异症囊肿行子宫全切除术及卵巢内异症囊肿剥除术或附件切除术的患者共30例,经病理确诊子宫腺肌病合并内异症囊肿共17例作为观察组;同期因宫颈上皮内瘤变(CIN)Ⅲ行子宫全切除术的患者10例作为对照组.将观察组患者的在位内膜、卵巢内异症囊肿病灶、子宫腺肌病病灶和对照组的子宫内膜组织进行石蜡切片,免疫组化Envision二步法检测SF-1蛋白的表达.结果 两组患者在位内膜的腺体和间质细胞中均无SF-1蛋白表达;观察组卵巢内异症囊肿病灶的间质细胞核SF-1蛋白的阳性表达率为14/17,SF-1蛋白在卵巢内异症病灶的腺体细胞及子宫腺肌病病灶中均无表达.结论 卵巢内异症囊肿与子宫腺肌病病灶中SF-1蛋白表达的差异可能在疾病的发生与发展中具有重要意义.

Expression of steroidogenic factor 1 in ovarian endometriosis and adenomyosis

Objective To investigate the expression of steroidogenic factor 1 ( SF-1 ) in eutopic endometrium,ovarian endometriosis (EM) and adenomyosis.Methods From Jan.2008 to Dec.2010,30 patients with both ovarian endometriotic cysts and adenomyosis underwent hysterectomy,cystectomy or adenxectomy in Peking University First Hospital.The combination of ovarian EM and denomyosis were confirmed in 17 cases.In the mean time,endometria form 10 patients with cervical intraepithelial neoplasm ( CIN ) Ⅲ underwent hysterectomy were selected as controls.The expression of SF-l in eutopic endometrium,ovarian EM and adenomyosis was detected by immunohistochemistry staining.Results No immunoreactivity of SF-l was observed glandular cell and stromal cell in eutopic endometrium of both groups.14/17 of positive rate of SF-l were observed in lesions of ovarian endometriosis.SF-l protein was not expressed in the endometrial glandular cells of ovarian EM and in adenomyosis foci.Conclusion The differences of SF-l expression in ovarian endometrioma and adenomyosis foci might mediate the development of the disease.
