【摘要】 目的:比较延时摄像胚胎观测技术(time-lapse)培养和常规体外受精(IVF-ET)胚胎培养对临床结局的影响。方法:回顾性分析2016年8月-2017年5月58例time-lapse培养周期和125例常规IVF胚胎培养周期的临床结果。比较time-lapse培养周期和常规IVF胚胎培养周期的卵裂数、D3优质胚胎数、D3可用胚胎数、种植率、临床妊娠率。结果:time-lapse培养周期组和常规IVF胚胎培养周期组的卵裂数、D3优质胚胎数、D3可用胚胎数、多胎率、种植率、累计移植次数和累计妊娠率比较差异均无统计学意義(P>0.05),两组临床妊娠率(62.5% vs 41.0%)比较差异有统计学意义(P<0.05)。结论:延时摄像胚胎观测技术(time-lapse)有助于预测胚胎发育潜能,可以改善胚胎选择方法,对传统的胚胎挑选给予新的思路。

[Abstract] Objective: To compare the clinical outcomes of time-lapse embryo observation (time-lapse) and conventional in vitro fertilization (IVF-ET) embryo cultures. Method: The clinical results of 58 time-lapse cycles and 125 conventional IVF embryo culture cycles from August 2016 to May 2017 were analyzed retrospectively. The number of cleavage, number of high-quality embryos (D3), number of available embryos (D3), implantation rate and clinical pregnancy rate were compared between time-lapse lapse culture cycle and conventional IVF embryo culture cycle. Result: There was no significant difference in the number of cleavage, number of high-quality D3 embryos, number of available D3 embryos, multiple embryo rate, implantation rate, cumulative transfer times and cumulative pregnancy rate between the time-lapse cycle group and the conventional IVF cycle group (P>0.05), The clinical pregnancy rate (62.5% vs 41.0%) was statistically different between the two groups (P<0.05). Conclusion: Time-lapse imaging (time-lapse) can be used to predict the development potential of embryos, improve the method of embryo selection, and give new ideas on the selection of conventional embryos.

在体外受精-胚胎移植(IVF-ET)过程中,胚胎的发育潜能是影响临床结果的重要因素[1]。因此,如何正确判断和选择具有良好发育潜能的胚胎,保证较好的临床妊娠结局已成为胚胎学研究的焦点[2-3]。延时摄像技术(time-lapse,TLI)是一种瞬时曝光连续拍摄的成像技术[4-6],通过对胚胎整个体外培养阶段进行监测,保证观察过程中胚胎发育环境的稳定,还能获取胚胎发育各个阶段的形态以及各事件发生的特定时间,为胚胎形态评估提供更为客观、精准的方式,进而根据胚胎动力学参数有效地评估胚胎的发育潜力,为筛选出最优发育条件的胚胎进行移植。本研究旨在分析比较TLI培养和常规IVF胚胎培养对临床结果的影响,探讨TLI培养是否更有利于选择高潜能胚胎。
