  • 辅助生殖技术与子代神经系统疾病的相关性研究回顾

    辅助生殖技术是目前治疗不孕症的主要手段之一。由于辅助生殖技术涉及对卵泡发育、精卵结合、胚胎形成、转运、种植过程的人为干预,自 1978 年首例试管婴儿诞生以来,其安全性,尤其是对子代健康的影响一直受到人们的关注。神经系统疾病是常见的出生缺陷之一。由于神经系统疾病通常影响儿童的精神、情绪、智力、运动、语言等关键能力,且神经系统的损伤往往不可修复,因此婴幼儿一旦罹患神经系统疾病对家庭和社会来说无疑是巨大的打击与负担。该文就辅助生殖技术与几种常见的子代神经系统疾病如智力低下、脑瘫、癫痫的关系进行了综述,并对辅助生殖技术对子代神经系统的安全性进行评价,从而进一步指导临床不孕症的治疗及围产期的母儿监护。

  • Diagnosis and treatment of emergency complications after oocyte retrieval with assisted reproductive technology

    Objective To retrospectively analyze the emergency complications of the patients after oocyte retrieval with assisted reproductive technology (ART), and analyze the corresponding strategies. Methods The clinical data of patients after oocyte retrieval with ART between January and December 2016 were retrospectively anayzed. The postoperative emergency complications were observed. Results A total of 5 013 patients were included in the study. The common emergency complications after oocyte retrieval included vaginal bleeding in 137 cases (2.73%) , ovarian hyperstimulation syndrome (OHSS) in 35 (0.69%), hematuria caused by bladder injury in 11 cases (0.21%), pelvic infection in 3 (0.06%), and vagal reflex in 2 (0.04%). OHSS was related to age, the number of basal follicles, the number of oviposaccharides and the estradiol level on the day of human chorionic gonadotropin injection, but not related to the body mass index and the number of days of gonadotropin use; which might be misdiagnosed most likely. Conclusions OHSS is one of the common and severe emergency complications after oocyte retrieval with ART, which should be concerned. Active treatment of complications is helpful to reduce the incidence of emergency complications after oocyte retrieval with ART.

  • Associations between ESR1 gene intron 1 polymorphisms and premature ovarian failure: a meta-analysis based on case-control studies

    ObjectiveTo explore the associations between estrogen receptor α (ESR1) gene intron 1 PvuⅡ (−397 T/C, rs2334693), XbaⅠ (−351 A/G, rs9340799) polymorphisms and premature ovarian failure (POF).MethodsLiterature published before February 2021 were retrieved in PubMed, Web of Science, China National Knowledge Infrastructure, Wanfang, and CQVIP databases, according to the inclusion and exclusion criteria developed before. Odds ratio (OR) and 95% confidence interval (CI) were used for data analysis, the Q test and I2 statistic were used for heterogeneity analysis. Random-effect model or fixed-effect model was used according to I2 value. All analyses were performed by RevMan 5.3 software.ResultsSix case-control studies were included in this meta-analysis. For the associations between ESR1 gene intron 1 PvuⅡ polymorphisms and POF, there was no statistical difference in TT vs. CC model [OR=0.72, 95%CI (0.31, 1.70), P=0.46], TC vs. CC model [OR=1.09, 95%CI (0.83, 1.43), P=0.54], recessive model [OR=1.08, 95%CI (0.68, 1.70), P=0.74], or dominant model [OR=0.77, 95%CI (0.42, 1.42), P=0.41]. For the associations between ESR1 gene intron 1 XbaⅠ polymorphisms and POF, there was no statistical difference in AA vs. GG model [OR=0.88, 95%CI (0.44, 1.75), P=0.72], AG vs. GG model [OR=1.23, 95%CI (0.84, 1.79), P=0.29], recessive model [OR=1.14, 95%CI (0.81, 1.61), P=0.44], or dominant model [OR=0.75, 95%CI (0.41, 1.35), P=0.34], either. No statistical difference was found in the ethno-based subgroup analyses (P>0.05). Most models had obvious heterogeneities.ConclusionsCurrent evidence can’t confirm the associations between ESR1 gene PvuⅡ, XbaⅠ polymorphisms and POF. High-quality, multi-central and large-sample studies are still necessary to support this conclusion.
