玻璃化冻融囊胚助孕妊娠妇女娩出胎盘Grb10表达分析研究

目的 对玻璃化冻融囊胚助孕妊娠妇女娩出胎盘中生长因子受体结合蛋白10(Grb10)表达进行分析,评价其安全性.方法 收集2012年1月至2014年5月在福建省妇幼保健院产科门诊玻璃化冻融囊胚助孕妊娠的妇女(观察组)50例及同期自然妊娠妇女(对照组)50例病例数据和胎盘标本.采用免疫组织化学、Western blot检测胎盘Grb10蛋白的表达,Real-time PCR检测Grb10 mRNA表达.对两组妊娠妇女的产科结局及胎盘Grb10的表达进行比较分析.结果 两组孕龄、胎龄,胎儿性别、体质量、身长、头围、腹围比较差异均无统计学意义(P＞0.05),娩出胎盘面积、胎盘质量比较差异有统计学意义(P＜0.05).两组胎盘组织Grb10蛋白表达率、表达强度、免疫组织化学评分比较差异均无统计学意义(P＞0.05).Real time PCR、Western blot分析结果进一步显示两组胎盘组织中Grb10 mRNA与蛋白表达差异均无统计学意义(P＞0.05).结论 玻璃化冻融囊胚助孕有可能会增加娩出胎盘的面积与质量.但发育相关分子Grb10在胎盘的表达未见明显改变.

Placental Grb10 expression analysis for evaluation of security for blastocyst vitrification

Objective To analyze the expression of the placenta Grb10 from women conceived by transferred thawed blastocyst,and to evaluate the security of blastocysts vitrification.Methods A cross-sectional study was performed in the Department of Obstetrics and Gynecology of Fujian Provincial Maternity and Children's Hospital from January 2012 to May 2014,50 women conceived by transferring thawing blastocyst and 50 natural pregnancy control women were enrolled in this study.The expression of Grb10 protein was detected by immunohistochemistry and Western blot,and the expression of Grb10 mRNA was detected by Realtime PCR method.Results Comparison of two cases of gestational age,gestational age,fetal sex,fetal body weight,body length,head circumference,abdominal circumference,there were no significant differences(P＞0.05),comparison of placental area,placental weight,the difference was statistically significant(P＜0.05).Real-time PCR and Western blot results showed that,there was no significant difference in the expression of Grb10 mRNA and protein between the two groups(P＞0.05).Conclusion Blastocysts vitrification may increase the area and quality of delivery of placenta,however,there was no significant change in the expression of Grb10 in placenta.
