出生体重是反映新生儿健康状况的一项重要指标。妊娠期母儿双方许多因素均影响胎儿的生长发育,决定其出生体重,但主要因素是胎盘功能和胎儿本身正常与否。产前检测中,血清 SP_1(胎盘合体滋养层细胞分泌的妊娠特异β-糖蛋白)含量可作为衡量胎盘功能的一项指标,而尿雌三醇/肌酐(E/C)比值,则能较稳定地反映胎儿-胎盘单位的功能状况。本文试图探讨孕38～42周孕妇血清 SP_1量和尿 E/C 比
Birth weight is an important indicator of a newborn’s health. Many factors during pregnancy both affect the fetus’s growth and development, determine their birth weight, but the main factor is the placental function and the fetus itself is normal or not. Prenatal testing, serum SP_1 (placental syncytiotrophoblast secretion of pregnancy-specific β-glycoprotein) content can be used as a measure of placental function index, and urinary estriol / creatinine (E / C) ratio, you can compare Stably reflect the fetal - placental function of the unit status. This article attempts to explore pregnant 38 ~ 42 weeks pregnant women serum SP_1 and urinary E / C ratio
