h CG的终末代谢产物是 β-核心片段 ,作者曾报道 h CG的 β-核心片段可作为滋养叶细胞活动的标志 ,临床正常的中期妊娠孕妇尿 h CG的β-核心片段升高最终可发生先兆子痫。本研究的目的是评估中期妊娠孕妇尿 h CG的β-核心片段是否能预示小于胎龄儿 (SGA)的发生。故作者从 1977 The final metabolite of hCG is the beta-core fragment. The authors have reported that the beta-core fragment of hCG can serve as a hallmark of trophoblast cell activity, and the elevated beta-core fraction of urinary hCG in clinically normal midterm pregnant women eventually Pre-eclampsia occurs. The purpose of this study was to assess whether beta-core fragments of urine h CG in pregnant women in mid-term pregnancies predict predilection for gestational age (SGA). The author from 1977
