常规IVF不受精周期行补救卵母细胞单精子注射

 【目的】探讨常规体外受精胚胎移植（in vitro fertilization and embryo transfer,IVF-ET）不受精时,应用卵母细胞单精子显微注射（intracytoplasmic sperm injection,ICSI）技术进行补救授精的临床意义。【方法】2001年8月～2005年8月,在499个常规IVF-ET周期中有25个周期完全不受精,进行补救ICSI,并与同期实施的179个正常ICSI周期进行比较。【结果】补救ICSI组与正常ICSI组比较,HCG日平均血清雌二醇水平、每个成熟卵泡平均血清雌二醇量、每个周期的获卵数无明显差别,补救ICSI受精率为57.7%,低于正常ICSI组（67.8%）,补救ICSI组平均每个周期获得胚胎数（7.8±3.9）比正常ICSI（10.0±4.9）组少,且有统计学意义（P〈0.01）。补救ICSI组≥4细胞的胚胎占总胚胎数的54.5%,低于正常ICSI组（87.5%）,有统计学意义（P〈0.01）。正常ICSI组妊娠率为38.5%,补救ICSI组无一例妊娠。补救ICSI组中有8例在下一周期行ICSI,有2例妊娠并分娩2个健康女婴。【结论】补救ICSI虽可以避免取消IVF周期，但其受精率和妊娠率低，其临床应用价值还有待于进一步探讨。对于常规IVF不受精的患者，再次治疗时可考虑行ICSI助孕。

Successful Pregnancy and Delivery after Multifetal Pregnancy Reduction in AWoman with Monochorionic Triplet Pregnancy Following Intracytoplasmic Sperm Injection and the Transfer of Frozen-thawed Embryos

This was the first report of multifetal pregnancy reduction （MFPR） with mono- chorionic triplet pregnancy following ICSI and the transfer of frozen-thawed embryos. A 30-year-old woman who had undergone ICSI and the transfer of frozen-thawed embryos subsequently developed monochorionic triplet pregnancy. She did a multifetal pregnancy reduction to remove one embryo limb from the fetal sac and remained a singleton pregnancy after pregnancy reduction. At last she delivered a healthy baby girl at 40 weeks of gestation. In conclusions, an early stage fetal reduction, selection of the appropriate reduction week, and the expertise of a highly experienced doctor using ultrasound can ensure a wonderful pregnancy outcome in monozygotic multiple pregnancies.     

Impact of Blood Clot in Oocyte-Corona-Cumulus Complex during in vitro Fertilization and Embryo Transfer

Objective To study the impact of blood clots in the oocyte-corona-cumulus complexes (OCCC) during in vitro fertilization and embryo transfer (IVF-ET). Methods The OCCCs were harvested from the patients undergoing long protocol ovarian hyperstimulation. The OCCCs with blood clots removed or not, were randomly grouped into A or B. The OCCCs without blood clots were group C (the control). Results The patient’s age, infertility duration, the average GN consumption, the average days of superovulation and an average number of harvested oocytes showed no significant difference in the 3 groups. The fertilization rate and 2PN rate in group A were the highest, which were 85.4% and 71.1%, respectively, followed by group C, which were 77.5% and 64.9%, respectively. The lowest fertilization rate and 2PN rate were in group B, 75.8% and 62.2%, respectively. Those in group A were significantly higher than those in groups B and C (P<0.01), while there was no significant difference between group B and group C . The implantation rates and pregnancy rates showed no significant difference in the 3 groups after transplantation, even if group A got the highest rate among the 3 groups. Conclusion Removing the blood clots in OCCC can improve the outcome of IVF-ET without increasing the cost and complexity of the operation.

体外受精/卵胞浆内单精子注射术后宫内单胎妊娠早期自然流产的相关因素

目的：探讨体外受精(in vitro fertilization,IVF)/卵胞浆内单精子注射(intracytoplasmic sperm injection,ICSI)术后宫内单胎妊娠病例发生早期自然流产的相关因素,为早期自然流产的预防提供可行依据。方法：采用成组病例-对照研究,对2013年1月至2014年5月在湘雅医院生殖医学中心行IVF/ICSI术后的单胎妊娠病例进行回顾性分析,以早期自然流产夫妇(96对)为病例组,足月活产分娩夫妇(593对)为对照组,分析早期自然流产的相关因素。结果：多因素分析显示女方年龄大、有自然流产史以及男方精子DNA碎片指数(DAN fragmentation index,DFI)高为IVF/ICSI术后早期自然流产的独立危险因素(P<0.05)。结论：IVF/ICSI术后发生早期自然流产受多因素的影响。女方年龄越大(>30岁)、有自然流产史或男方精子DFI越高(≥15%),IVF/ICSI术后发生早期自然流产的风险越大。     

Clinical Analysis on Laparoscopic Salpingectomy for Ectopic Pregnancy Following IVF/ICSI-ET

Objective To investigate whether laparoscopic surgery is valuable during early pregnancy and its influence on delivery outcome of the patients.Methods A retrospective analysis was undertaken of 14 heterotopic pregnancies conceived by IVF/ICSI-ET and underwent laparoscopic salpingectomy from December 2001 to September 2009.Results The mean age of 14 patients was 29 ± 5.3 years with range of 21-39 years.The ectopic pregnancy was located in the ampulla（11 patients,78.57%） and isthmus（3 patients,21.43%）.All 14 patients underwent successful laparoscopic salpingectomy without complications.Eleven（78.57%） patients delivered live singleton infants at full term via caesarean section while 3（21.43%） had spontaneous abortion.The birth weight of viable newborns ranged from 2 600 g to 3 720 g and had a high Apgar score.Conclusion During early pregnancy,the heterotopic pregnancy should be diagnosed and treated early and laparoscopic salpingectomy can be a safe and effective choice.The well experienced surgeons and accessibility of the modern equipments are mandatory.

Assisted Reproduction of Pretreatment with Laparoscopic “Core-pulling” Salpingectomy for Patients with Hydrosalpinx before in vitro Fertilization Embryo Transfer

Objective To investigate the reproduction-assisting effects of laparoscopic ＂corepulling＂ salpingectomy for patients with hydrosalpinx on ovarian reserve,responsiveness to stimuli and outcomes of in vitro fertilization and embryo transfer（IVF-ET）.Methods Infertile females receiving treatment in Reproductive Medicine Center of Yantai Yuhuangding Hospital due to fallopian tube disorders（n=214） were enrolled from July 2006 to December 2007 and further divided into three groups.＂Core-pulling＂ procedure group（group A） consisted of patients receiving pretreatment with ＂corepulling＂ salpingectomy due to hydrosalpinx in our center（n=31）,wherein 16 patients received IVF-ET.Conventional procedure group（group B） consisted of patients receiving conventional salpingectomy for hydrosalpinx or ectopic pregnancy in our center or other institutes prior to IVF-ET（n=59）.Control group（group C） consisted of patients receiving IVF-ET without the history of previous hydrosalpinx or salpingectomy（n=124）.Results At baseline,the antral follicle count of group B was significantly less than that of groups A and C（8.6±2.5 vs 8.3±2.0 vs 9.8±2.4）.The mature oocytes retrieved numbered less than the other two groups,in a statistically significant manner compared with group C（13.1±5.7 vs 10.6±5.0 vs 12.0±6.2）.Patients of groups A and B received more gonadotropin while the dosage of group B differed significantly from group C（31.0±17.7 vs 37.6±8.3 vs 30.0±4.6）.E2 level on hCG injection day was slightly lower in group B than in the other two groups,statistically significant compared with that of group C,but not compared with that of group A.After receiving IVF-ET,patients of group A showed significantly higher conception rate than groups B and C（62.5% vs 43.6% vs 39.2%）.Conclusion Compared with the conventional procedure,laparoscopic ＂core-pulling＂ salpingectomy should be recommended for patients with hydrosalpinx intending to receive IVF-ET,which did not interfere with the ovarian reserve or responsiveness but improve the conception rate in clinical practice.

目的评价亲情护理在辅助生殖技术中的体外授精．胚胎移植（WF-ET）忠者中的应用效果，提高患者满意度。方法随机将2006年1-6月本中心100例IVF—ET患者分为，实验组与对照组各50例，对照组采用传统的护理模式，实验组采用亲情护理模式。结果对照组患者的满意度为74％，实验组患者的满意度为98％，两组患者满意度有显著性差异p〈0．01（u=3．602）。结论亲情护理在IVF-ET中的应用取得了明显的临床效果，减少了护理纠纷，同时也说明了医护人员服务观念改变的必要性。     

卵泡液和血清EG-VEGF、VEGF和TGF-β1水平与IVF妇女卵巢反应的关系及其对妊娠结局的预测价值

目的 探讨卵泡液和血清中内分泌腺来源的血管内皮生长因子(EG-VEGF）、血管内皮生长因子（VEGF）和转化生长因子β1（TGF-β1）水平与体外受精（IVF）妇女卵巢反应的关系及其对妊娠结局的预测价值。方法 选择60例因输卵管和（或）男性因素而接受体外受精-胚胎移植(IVF-ET)治疗的不孕症患者作为研究对象。ELISA法检测取卵当日卵泡液中和取卵后第2天血清中EG-VEGF、VEGF和TGF-β1的水平,分析其与卵巢反应和IVF妊娠结局的关系。结果 卵泡液EG-VEGF、血清EG-VEGF、卵泡液VEGF浓度均与控制性超排卵周期中人绒毛膜促性腺激素(hCG)注射日血清雌二醇（E₂）浓度呈显著负相关（r=－0.622, P<0.01; r=－0.511, P<0.01; r=－0.427, P<0.01）,卵泡液EG-VEGF与卵泡液VEGF浓度呈显著正相关（r=0.354, P<0.01）。60例不孕症患者中,妊娠31例,未妊娠29例。与非妊娠组比较,妊娠组hCG注射日血清E₂浓度较低（P<0.05）,而血清EG-VEGF浓度较高（P<0.01）;而两组间卵泡液和血清VEGF、TGF-β1的浓度比较,差异均无统计学意义（P>0.05）。结论 卵泡液和血清EG-VEGF及卵泡液VEGF水平均与卵巢反应呈显著负相关。黄体早期血清EG-VEGF水平与IVF妊娠结局相关,可能具有预测IVF妊娠结局的潜在价值。
