直至 1999年 ,仍尚未发现理想的、能正确地预测胎盘剥离程度的指标[1] 。但近年来 ,该领域的研究已逐渐增多。本文将重点综述预测胎盘早剥发生指标的研究进展。一、Ｇｌｕ 2 98Ａｓｐ基因突变体内皮细胞一氧化氮合酶基因中的Ｇｌｕ 2 98Ａｓｐ基因突变体与胎盘早剥发生有关[2 ] Until 1999, there was still no ideal indicator that correctly predicted the degree of placental detachment [1]. But in recent years, the research in this field has been gradually increasing. This article will focus on review of the prediction of placental abruption indicators of research progress. First, Glu 2 98Asp gene mutations in endothelial nitric oxide synthase gene Glu 2 98Asp gene mutations associated with placental abruption [2]
