At term, the pregnancy-associated plasma protein B (PAPP-B) level in normal pregnancy was correlated with placental and newborn weights, but not with nine other normal obstetric variables. It was lower in pregnancies complicated by diabetes or severe toxaemia, and higher in twin pregnancies.
足月时,正常妊娠中妊娠相关血浆蛋白B(PAPP - B)水平与胎盘和新生儿体重相关,但与其他九个正常产科变量无关。在合并糖尿病或重度子痫前期的妊娠中其水平较低,而在双胎妊娠中较高。
