摘　　要：背景:目前对多囊卵巢综合征的治疗大多是超指征用药,对其治疗仍面临很大的挑战。研究证明人脐带间充质干细胞可修复卵巢功能,但鲜有研究报道其对多囊卵巢综合征的治疗作用。目的:观察人脐带间充质干细胞对多囊卵巢综合征的治疗作用,并初探线粒体自噬与人脐带间充质干细胞改善多囊卵巢综合征症状的相关性。方法:C57BL/6J小鼠皮下连续注射20 d脱氢表雄酮构建多囊卵巢综合征模型,通过尾静脉注射人脐带间充质干细胞(2×10^(6)),治疗后连续10 d取阴道内分泌物检测小鼠的发情周期。治疗后2周,采用ELISA检测小鼠外周血性激素水平,包括黄体生成素和卵泡刺激素;苏木精-伊红染色进行卵巢组织病理学评估,最后通过透射电镜观察卵巢组织中线粒体自噬反应。结果与结论:(1)经人脐带间充质干细胞治疗后,多囊卵巢综合征小鼠卵巢中出现了处在原始卵泡、初级卵泡、次级卵泡等各阶段的卵泡,而且可见黄体组织,说明小鼠排卵功能明显改善;(2)经人脐带间充质干细胞治疗后,多囊卵巢综合征小鼠性激素水平恢复至正常;(3)未经治疗的多囊卵巢综合征小鼠长期处在动情期,缺乏动情间期和动情前期,经过人脐带间充质干细胞治疗的多囊卵巢综合征小鼠动情周期恢复到正常水平;(4)经人脐带间充质干细胞治疗后,多囊卵巢综合征小鼠卵巢组织中的线粒体自噬明显减少;(5)结果表明,人脐带间充质干细胞可有效改善多囊卵巢综合征小鼠内分泌紊乱,促进排卵,这可能与抑制线粒体自噬相关。BACKGROUND:At present,many drugs used in the treatment of polycystic ovary syndrome are super-designated drugs,and the treatment of patients with polycystic ovary syndrome still faces great challenges.Studies have shown that human umbilical cord mesenchymal stem cells can repair ovarian function,but few studies have reported their therapeutic effect on polycystic ovary syndrome.OBJECTIVE:To investigate the therapeutic effect of human umbilical cord mesenchymal stem cells on polycystic ovary syndrome,and to preliminarily explore the correlation between mitochondrial autophagy and the improvement of polycystic ovary syndrome by human umbilical cord mesenchymal stem cells.METHODS:Polycystic ovary syndrome mouse model was established by subcutaneous injection of dehydroepiandrosterone for 20 days into C57BL/6J mice.Human umbilical cord mesenchymal stem cells(2×10^(6))were injected through the caudal vein.After treatment,vaginal secretions were collected for 10 consecutive days to detect the estrus cycle of mice.At 2 weeks after treatment,the levels of sex hormones in the peripheral blood of mice,including luteinizing hormone and follicle-stimulating hormone,were detected by ELISA.Hematoxylin-eosin staining was used to evaluate ovarian histopathology.Finally,mitochondrial autophagy in ovaries was observed by transmission electron microscopy.RESULTS AND CONCLUSION:(1)After human umbilical cord mesenchymal stem cell therapy,follicles at different stages(primitive follicles,primary follicles,and secondary follicles)appeared in the ovary of polycystic ovary syndrome mice,and luteal tissue could be seen,indicating that ovulation function of mice was effectively improved.(2)Polycystic ovary syndrome mice treated with human umbilical cord mesenchymal stem cells had sex hormone levels.(3)Untreated polycystic ovary syndrome mice were found to be in the estrous stage for a long time,lacking estrous interphase and estrous phase,but after human umbilical cord mesenchymal stem cell therapy,the estrous cycle returned to a normal l
