THE CORRELATION OF ANTITROPHOBLAST ANTIBODY, EMAB AND HCG-AB WITH IVF-ET PREGNANCY OUTCOMEYANG ZONG-ZHI, SONG DONG-PO, ZOU SHU-HUA, et al（Medical and Health Care Center For Women and Childen of Qingdao, Qingdao 266011, China）［ABSTRACT］ObjectiveTo assess the effect of antitrophoblast antibody, EmAb and HCG-Ab on in vitro fertilization and embryo transfer outcome.MethodsThis study included 140 infertility women of unexplained reasons, salpingemphraxis and/or male factor undergoing IVF-ET, of whom, 31 with repeated failure of implantation; 26 with biochemical loss of pregnancy; 18 with clinical pregnancy loss. Sixty-five with clinical pregnancy served as control group.

目的 探讨抗滋养细胞膜抗体、抗子宫内膜抗体、抗HCG抗体对体外受精-胚胎移植妊娠结局的影响方法选择2002年1月～2007年7月在本生殖医学中心由于不明原因性不育、女方输卵管因素和男方轻度少弱精子症因素不育而接受IVF-ET治疗的妇女140例，其中次植失败31例，生化妊娠丢失26例及临床妊娠丢失18例，持续妊娠65例。

Most IVF pregnancies are singletons but the rates of multiple gestations are much higher than those seen in spontaneous conceptions: approximately 30% of all pregnancies occurring via IVF are multiples, the majority being twins.

大多数IVF婴儿是独生子，但是与自然怀孕相比，IVF多胎怀孕的几率要高得多：全部IVF受孕婴儿中约有30%是多胞胎，绝大多数是双胞胎。

4H was the best time of bovine oocyte activationin the 6-DAMP, and the cleavage rates and blastula rates could reach 85.1% and 26.8%. 4. IVF-100 was used in vitro fertilization, because IVF-100 was not needed to prepare usually,store conveniently, and gain a higher cleavage rates. After the oocytes have matured for 20h, theywere digested by permease and treated with suctionpipe.

由于IVF-100无需经常配制、保存方便且可以获得较高的卵裂率，所以本实验采用IVF-100为受精液，卵母细胞成熟20小时后采用透酶+口吸管消化的方法处理，获得了较好的受精效果，卵裂率可达(76.8％)。

The results show that: 1 supplementation of protein to maturation media improves cumulus expansion in vitro compared to the protein-free control, but cumulus expansion is not necessarily related to oocyte nuclear maturation in pigs, and cumulus expansion is not the criterae for determination of nuclear maturation of pig oocytes, but only the exclusion of the first polar body; 2 exposure of pig COCs to hormone supplements for 23-24 hours improved cumulus expansion but had no significant effect on nuclear maturation compared to that for 46-48 hours; 3 under our research conditions, supplementation of different proteins into different maturation media has different effects on porcine oocyte nuclear maturation, but has no significant effect on subsequent embryonic development after IVF; 4 the nuclear maturation rates of pig oocytes matured in mTCM+pFF and mNCSU+pFF are superior than that in mNCSU+FCS; 5 different maturation media have no effect on pig oocyte cumulus expansion and subsequent embryonic development after IVF.

结果显示：(1)在成熟液中添加蛋白质可以加强卵丘细胞的扩散，但猪卵母细胞的核成熟与其周围的卵丘细胞扩展没有必然的联系，卵丘细胞扩散或成放射状不宜作为猪卵母细胞核成熟的标准，只有排出第一极体才能作为猪卵母细胞核成熟的标志；(2)在猪COCs的46-48小时成熟培养的后23-24小时阶段去除成熟液中的激素不但可以保证卵母细胞的核成熟率，而且可加强卵丘细胞的扩散；(3)在现有实验条件下，在mTCM和mNCSU中添加10％pFF与在mNCSU中添加10％FCS相比可获得较高的猪卵母细胞核成熟率；(4)在不同的成熟液中添加不同的蛋白质对猪卵母细胞核成熟率的影响效果不一样，但对体外受精后的早期胚胎发育影响不明显；(5)成熟液种类对猪卵母细胞的卵丘细胞扩散和体外受精后的早期胚胎发育无显著影响。

We further examined the effect of change of histone acetylation level in developmentof IVF and NT embryos.

试验还进一步研究了组蛋白乙酰化修饰的变化对早期IVF和核移植胚发育的影响。

Objective To investigate the relationship between ovum fertilization rate and sperm morphology, acrosome reaction in IVF and to explore the influence of parameters of sperm on fertilization rate.

目的 研究体外受精(in vitro fertilization，IVF)中精子形态、顶体反应与卵子受精率之间的关系，分析精子各参数在IVF受精率方面的参考意义。

FISH technique could be performed for the detection of HBV in human blastomere cells,and it has great significance to reduce vertical transmission of HBV in IVF-ET.

荧光原位杂交技术可用于卵裂球细胞HBV感染的检测，在体外受精-胚胎移植实践中对降低HBV垂直传播有重要意义。

The results showed that there was no significant difference in three structure approach of liquid layers among which B was relatively higher;and it was considered that one-step dilution was an effective preservation method in that survival capacity with frozen and melted embryos freshly split,and survival capacity of frozen and melted IVF embryos split by one-step dilution by application minimum capacity refrigerant method with specific canaliculus were obviously higher than B.

结果，3种不同液体层构成间胚胎的存活能力无显著差异，B法较高；应用特定细管最小容量冷却法在冷冻溶解的新鲜分割胚、体外受精分割胚及冷冻溶解的体外受精分割胚一步法稀释后的存活能力均显著高于B法。结果表明，特定细管最小容量冷却法是更有效的保存方法。

By the research of sperm capacitation,the research of IVF has broken through obstacles and developed.

精子获能为体外受精研究获得突破性进展，为人类直接观察受精过程和研究受精机理奠定了基础。

This center passes classics rectum seminiferous duct crock abdomen, spermatic gland, prostate massages art extraction essence of life to be able to avoid this kind of injury and anguish very well, and obtain enough spermatozoon to be used at ICSI and IVF-ET, report as follows now.

梗概： 隨着现代辅助生殖技术的发展，体外受精-胚胎移植及其相关技术成为治疗不孕不育症主要方法之一，对于精液中有精子者一般通过患者手淫取精用于体外受精。
