目的 评估产后女性的认知功能,并分析其认知功能受损的特点,以及分析可能的影响因素。方法 病例组选取健康单胎足月顺产初产妇、二胎产妇,对照组选取一般资料匹配的未生育女性,选用蒙特利尔认知评估(Montreal Cognitive Assessment Test,MoCA)北京版、伯明翰认知评估量表(Birmingham Cognitive Screen test,BCoS)普通话版评估认知功能。结果 实际入组病例组80例产妇,均完成MoCA量表,共42例产妇完成BCoS量表,对照组30例均完成MoCA、 BCoS评估。产妇组(80例)MCA得分为(26.26±2.28)分,低于未生育女性对照组MoCA分数(27.47±1.28)分(P<0.05),产妇组认知障碍发生率为30%高于对照组6.7%(P<0.05)。初产妇组MoCA分数(26.52±2.13)分,认知障碍发生率为26%,二胎产妇组MoCA分数(25.83±2.49)分,认知障碍发生率为36.7%,两者对比无明显差别(P>0.05)。产妇组(80例)在MoCA量表视空间与执行功能分项得分低于对照组(P<0.01);产妇组BCoS评分在故事瞬时回想、苹果删除总数、听觉注意、规则转换、手势模仿5个分项低于对照组(P<0.05)。产妇的受教育年限、分娩镇痛麻醉、总产程时间是产后认知功能下降的影响因素(P<0.05)。结论 ①产后妇女可能发生认知功能障碍,但初产妇与二胎产妇的认知障碍发生率无明显差别。②MoCA量表可以用于产妇产后认知功能筛查,BCoS量表可做为全面评估产妇产后认知功能的工具,产妇产后认知受损主要在视空间、注意力、执行功能(实践与行动能力)、记忆力领域。③产妇的受教育年限、分娩镇痛麻醉、总产程时间是产后认知功能下降的影响因素。
Objective To evaluate the cognitive function of postpartum women, and analyze the characteristics of cognitive dysfunction and the possible affecting factors. Methods The case group selected healthy single-born full-term primiparae (50 cases) and second birth parturient (30 cases), and the control group (30 cases) selected non-fertile women with general data matching. The Montreal Cognitive Assessment Test (MoCA) Beijing version and Birmingham Cognitive Screen test(BCoS) were used to evaluate cognitive function. Results Of the 80 cases in the case group, all completed the MoCA test, only 42 cases completed the BCoS test. The 30 cases in the control group all completed the MoCA and BcoS.The MoCA score of the case group (80 cases) was (26.26±2.28), which was lower than that of the control group (27.47±1.28) (P<0.05). The incidence of cognitive impairment in the case group was 30%, higher than the control group 6.7% (P<0.05). The MoCA score of the primiparae group was (26.52±2.13); the incidence of cognitive impairment was 26%; the MoCA score of the second birth parturient group was (25.83±2.49); the incidence of cognitive impairment was 36.7%.There was no significant difference in the MoCA score and the incidence of cognitive impairment between primiparae and second birth parturient (P> 0.05).The case group had lower scores on visual space and executive function of MoCA test than the control group (P<0.01).The score of BCoS test in the case group was lower than that in the control group in the five items of the instantaneous recall item of the story, apple deletion, auditory attention, Birmingham rule conversion and gesture imitation (P<0.05).The years of education, labor analgesia, and the total duration of labor were the factors that affected the cognitive function of postpartum women (P<0.05). Conclusion ①Postpartum women may have cognitive dysfunction, but there was no significant difference in the incidence of cognitive impairment between primiparae and second birth parturient group. ②The MoCA test can be used for the screening of cognitive impairment of postpartum women, and the BCoS test can be used as a tool to comprehensively evaluate the cognitive function of postpartum women. The cognitive impairment of postpartum women was mainly in the fields of visual space, attention, executive function (practice and action ability), and memory. ③The years of education, labor analgesia, and the total duration of labor were the factors that affect the cognitive function of postpartum women.

目的 探讨骨髓间充质干细胞源性微泡(BMSC-MV)修复大鼠早发性卵巢功能不全的自噬机制。方法 大鼠骨髓分离培养骨髓间充质干细胞;超速离心法从骨髓间充质干细胞培养液中分离微泡;腹腔注射顺铂溶液制备早发性卵巢功能不全(POI)模型,制备后3 d尾静脉取血ELISA检测血清雌二醇(E2)及卵泡刺激素(FSH);尾静脉注射BMSC-MV移植治疗POI大鼠模型,移植后28 d尾静脉取血ELISA检测E2、FSH及抗苗勒管激素(AMH),同时取卵巢组织检测自噬相关蛋白LC3及P62。结果 模型对照组及微泡移植组在模型制备后3 d的E2 含量低于正常对照组,FSH 含量高于正常对照组(P<0.001);微泡移植组在移植后28 d的E2、AMH含量高于模型对照组(P<0.001),FSH含量低于模型对照组(P<0.001);微泡移植组的LC3较模型对照组表达升高,而P62表达降低(P<0.001)。结论 BMSC-MV介导自噬修复大鼠早发性卵巢功能不全。
Objective To investigate the autophagy mechanism of bone marrow mesenchymal stem cell-derived microvesicle (BMSC-MV) in repairing premature ovarian dysfunction in rats. Methods The whole bone marrow adherence method was used to isolate,culture and identify BMSCs of SD rats. Microvesicles were isolated from bone marrow mesenchymal stem cell by ultracentrifugation. Premature ovarian insufficiency (POI) model was prepared by intraperitoneal injection of cisplatin solution,and serum estradiol (E2) and follicular stimulating hormone (FSH) were detected by ELISA from tail vein 3 days after preparation. Rat model of POI was treated with BMSC-MV transplantation by tail vein. Blood from tail vein was collected 28 days after transplantation to detect E2,FSH and AMH by ELISA. Meanwhile,ovarian tissues were collected to detect autophagy-related proteins LC3 and P62. Results The E2 content of the model control group and the microvesicle transplantation group was lower than that of the normal control group,and the FSH content was higher than that of the normal control group (P<0.001). The content of E2 and AMH in the microvesicle transplantation group at 28 days after transplantation was higher than that in the model control group (P<0.001),and the content of FSH was lower than that in the model control group (P<0.001). Compared with the model control group,LC3 expression in the microvesicle transplantation group was increased,while P62 expression was decreased (P<0.001). Conclusion BMSC -MV mediate autophagy to repair premature ovarian insufficiency in rats.
