In the paternal or maternal alcohol exposure during pregnancy, parents with alcohol intake during pregnancy may damage DNA methylation and histone modifications of pre-implantation embryo. We provide prevent the harm of alcohol to the fetus.

在父性、母性孕期酒精暴露研究中，怀孕期间酒精摄入对植入前胚胎DNA甲基化及组蛋白修饰可能造成损害的差异，也为我们预防酒精对胎儿的伤害提供借鉴的作用。

The invasiveness of trophoblast is highly important for blastula implantation, placenta development, and the establishment of maternal-fetal circulation. The invasive abnormity of the trophoblast and abnormal remodeling of uterus spiral artery are the main reason causing pre-eclampsia, fetal growth restriction and spontaneous abortion.

滋养细胞侵袭能力对于囊胚植入、胎盘发育，并建立母-胎循环至关重要；滋养细胞侵袭功能异常，蜕膜螺旋动脉重塑不良是子痫前期、胎儿宫内生长迟缓、自然流产等妊娠相关疾病的主要原因。

Critics also question the need for gene editing when pre-implantation diagnosis ( PGD), which selects healthy IVF embryos by a DNA test, can do the job, too.

当胚胎植入前遗传学诊断（PGD）——通过DNA测试来选择健康的体外受精（IVF）胚胎——也可以达到同样目的时，批评者还质疑基因编辑的必要性。
