建立人卵细胞冷冻保存以及融解后受精和发育颇具实用价值。本文采用慢冷、快融法,结合使用丙二醇和蔗糖作为冷冻保护剂,对285个临床IVF未受精卵进行冷冻保存,3天至40天时间不等。冷冻存活率为54.73%,其中未成熟卵子51.72%,成熟卵子55.50%,二者无显著性差异(P>0.05)。冷冻损伤的卵子中,细胞膜损坏为96.89%,透明带破裂为13.18%。选择冻融后形态结构正常的126个成熟卵子进行胞浆内单个精子注射(ICSI),受精率达42.06%,其中50.94%受精卵子进一步发育成2~8细胞胚胎。来源于常规IVF未受精卵的再次受精率为40.74%,来源于ICSI未受精卵的再次受精率为36.73%。作者认为,必要时可以借助显微操作技术进行胚胎活检,了解部分染色体畸变情况,使卵子冷冻保存技术安全地应用于临床。

Preimplantation genetic diagnosis (PGD), a new prenatal diagnosis which can be offered to the couples who are at risk to give births to genetically affected offspring,is based on the techniques of in vitro fertilization (IVF) and early embryo biopsy.As one of the most common X?linked lethal genetic diseases,Duchenne muscular dystrophy(DMD) is one of the first group of genetic diseases which were chosen to be evaluated the possibility of clinical PGD.Here we present that the development of 3?multiplex(including DMD gene exon19,48 and SRY gene)and 4?multiplex(including DMD gene exon17 44,45and SRY gene)PCR amplifying both DMD gene and SRY gene on single lymphocytes and the analysis of their reliability.After analysis of 50 single normal male lymphocytes with these techniques,we found the successful amplification rates on single lymphocytes for DND gene exon17,19,44,45,48,and SRY gene are 92%,96%,94%,96%,94%and 94?96%respectively.We also found that the total amplification accurate rate for 3?multiplex and 4?multiplex are 96%(607/630)and 96%(807/840) respectively along with total false positive amplification rate 4.4%(4/90)and 3.3%(4/120) respectively after further analysis of 50 normal female lymphocytes and 50 DMD patient lymphocytes carrying a DMD gene deletion mutation involved exon44?49. Our results suggested that these techniques can be used for clinical PGD application which can analyze both sex and deletion mutation of DMD gene of the embryos at risk of being affected in DMD families carrying DMD gene deletion mutations involved exon17,19,44,45 and 48.These techniques are better than those only based on either sexdetermination of DMD deletion analysis which are available so far.
