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.
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.
【摘要】 目的 探讨各种不同体外受精（IVF）助孕方案对子宫腺肌病伴不孕症患者的疗效。 方法 对2006年1月-2009年6月进行IVF助孕治疗的子宫腺肌病伴不孕症患者63例的临床资料进行回顾性分析。根据是否应用长效促性腺激素释放激素激动剂（GnRH-a）及启动促性腺激素（Gn）时间分为超长方案、长效GnRH-a后长或短方案、常规长方案3组，对IVF助孕疗效进行分析。 结果 3种治疗方案的Gn刺激天数、Gn总量、获卵数、不良反应发生率和流产率比较无统计学意义（Pgt;0.05）；3种治疗方案的周期取消率为20.0%、7.7%、30.0%，比较有统计学意义（χ2=5.74，Plt;0.05），方案2的周期取消率低于方案1和方案3，有统计学意义（χ2=7.21，Plt;0.05）；3种治疗方案的继续妊娠率为23.0%、37.0%、15.3%，有统计学意义（χ2=11.31，Plt;0.05），方案2的继续妊娠率高于方案1和方案3，有统计学意义（χ2=8.52，Plt;0.05）。 结论 与超长方案和常规长方案相比，子宫腺肌病伴不孕症患者采用长效GnRH-a治疗后长方案或短方案行IVF助孕治疗，妊娠率升高，周期取消率降低。【Abstract】 Objective To investigate the effect of different in vitro fertilization (IVF) treatment protocols on infertile women with adenomyosis. Methods Sixty-four infertile women with adenomyosis who had IVF treatment cycles from January 2006 to June 2009 were retrospectively analyzed. According to administration of long course gonadotropin-releasing hormone agonist (GnRH-a) and the start time of gonadotropin (Gn), all participants were divided into three groups: the first group with ultra-long term protocol, the second group with long or short term protocol after administration of long course GnRH-a and the third group with routine long term protocol. Results There were no differences among the three groups with regard to days of Gn administration, amounts of Gn administration, numbers of retrieved oocytes, prevalence of poor response and miscarriage (Pgt;0.05). The cancelation rates of the three groups were 20.0%、7.7% and 30.0% respectively. There were significant differences in cancelation rates among the groups (χ2=5.74, Plt;0.05), and the cancelation rate in the second group was significantly lower than the other groups (χ2=7.21, Plt;0.05). The ongoing pregnancy rates of the groups were 23.0%、37.0% and 15.3% respectively. There were significant differences in ongoing pregnancy rates among three groups (χ2=11.31, Plt;0.05), and the ongoing pregnancy rate in the second group was significantly higher than the other groups (χ2=8.52, Plt;0.05). Conclusion Compared with the ultra-long term and routine long term protocol of IVF treatment in infertile woman with adenomyosis, the ongoing pregnancy rate might be higher and the cancelation rate might be lower in the long or short term protocol after administration of long course GnRH-a.
ObjectiveTo compare the clinical outcomes of different pituitary down regulation protocols with gonadotropin-releasing hormone agonist (GnRH-a) in patients undergoing in vitro fertilization and embryo transfer (IVF-ET) treatment. MethodsThe clinical data of 358 IVF cycles in women at 40 years old or younger from November 2012 to January 2013 in the West China Second University Hospital were analyzed retrospectively. All the 358 cycles were divided into two groups, according to whether the leading follicle diameter was <14 mm (group A, 158 cycles) or ≥14 mm (group B, 200 cycles) after discontinuing the GnRH-a. The clinical outcomes were compared between the two groups. ResultsCompared with group B, the amount of gonadotropins used was significantly more, and the time of gonadotropin use was also significantly longer in group A (P<0.05). However, the serum level of estradiol (E2), progesterone (P) and Luteinizing hormone (LH), incidence of premature P rise, retrieved ovum number, the rates of implantation, clinical pregnancy, miscarriage and live birth did not significantly differ between the two groups (P>0.05). ConclusionDiscontinuing the use of GnRH-a in early stage of controlled ovarian stimulation can keep effective pituitary down regulation and it has the same optimal clinical outcomes in patients undergoing IVF-ET.
ObjectiveTo explore the effect of chronic unpredictable mild stress (CUMS) on the reproductive function of mice and provide a suitable animal model for reproduction and stress. MethodsA total of 240 female Kunming mice were feed for 5 days, and then divided randomly into the control group (n=90) and experimental group (n=150). The mice in the experimental group were stressed by 9 chronic mild unpredictable stress factors for 4 weeks and validated by open field test and sucrose consumption test. We administrated pregnant mare serum gonadotropin (PMSG)/human chorionic gonadotropin (HCG) for induction of superovulation and observed the ovarian response and embryo development potential. ResultsAfter 4-week CUMS stimulation, the weight gain, 2% sugar consumption test and open field test were significantly different between the mice in two groups (P>0.05). After PMSG/HCG was administrated, the antra follicles and preovulatory follicles significantly reduced significantly in the experiment group than that in the control group (P<0.05); the number of oocytes, fertilization rate, 2-cell embryos, D4 embryos, blastocysts, high quality embryo rate and D5 bed points were all significantly decreased in the experiment group than those in the control group (P<0.05). ConclusionThe CUMS female Kunming mice model is a kind of emotional stress animal model with low reproductive function, which is effective, operable and repeatable; it could be used for further study on the mechanism of reproductive medicine.
ObjectiveTo quantify cytokine and chemokine mRNA expression in follicular fluid cells obtained at the time of oocyte retrieval before IVF in women with and without polycystic ovary syndrome (PCOS). MethodsBetween January and August 2014, 80 subjects undergoing IVF-ET were chosen to be studied. Among them, 40 had PCOS, and the other 40 were controls. Follicular fluid cells were subjected to quantitative RT-PCR to evaluate growth-regulated oncogene-α (GRO-α), tumor necrosis factor-α (TNF-α), interleukins (IL-6, IL-8) expression relative to β-actin. And the chemokine was measured in serum and follicular fluids by immunoassays. These mRNA transcriptions production was proved by sequencing. ResultsGRO-α, TNF-α, IL-6 and IL-8 mRNA were expressed in follicular fluid cells. Their expressions were significantly higher in PCOS compared with controls (P<0.05). They were also detected higher in PCOS than controls in serum and follicular (P<0.05), but the difference of IL-6 level between PCOS and controls in lean patients was not statistically significant (P>0.05). ConclusionGRO-α, IL-8, TNF-α, and IL-6 may play important roles in the occurrence and development of PCOS. PCOS may be a chronic immunological inflammatory disease.
Childhood obesity is a global public health problem that seriously affects the normal growth and development of children. In recent years, a large number of studies have pointed out that the intestinal microbiome is closely related to childhood obesity, and the treatment strategies targeting the intestinal microbiome have a certain improvement effect on childhood obesity. This article elaborates on the establishment and development of intestinal microbiome, intestinal microbiome characteristics, the mechanisms of intestinal microbiome involvement in the occurrence and development of childhood obesity, and potential intervention strategies, so as to provide more ideas for basic and clinical research on childhood obesity.
