Study on the Serum Levels of Placenta Growth Factor During Normal Pregnancy and in Patients with Pregnancy Induced Hypertension

目的 :检测正常妊娠及妊娠高血压综合征 (妊高征 )患者血清胎盘生长因子 ( Pl GF)的水平 ,探讨 Pl GF与妊高征发病的关系。方法 :采用酶联免疫吸附法 ( ELISA)检测 5 1例不同孕期健康孕妇 (正常妊娠组 )及 33例妊高征患者 (妊高征组 )血清 Pl GF水平。结果 :1正常妊娠过程中 ,Pl GF在早孕期最低为 ( 1 72 .89± 82 .76) ng.L-1,中孕期开始大幅度升高至 ( 62 3.0 5± 1 66.2 2 ) ng.L-1,晚孕期达高峰 ( 833.84± 35 8.2 4 ) ng;2妊高征组 Pl GF平均水平为 ( 32 5 .70± 1 62 .2 1 ) ng.L-1,显著低于正常妊娠晚孕期水平 ( P<0 .0 0 1 ) ,并随妊高征病情加重 ,Pl GF水平呈逐渐下降趋势 ( P<0 .0 0 1 )。结论 :妊娠过程中 ,Pl GF对胎盘血管的形成有重要调节作用 ,Pl GF的下降与妊高征发病有关。

Study on the Serum Levels of Placenta Growth Factor During Normal Pregnancy and in Patients with Pregnancy Induced Hypertension

Objective:To detect serum levels of placenta growth factor(PIGF)throughout normal pregnancy and in patients with pregnancy-induced hypertension(PIH)as well as to explore the relationship between P1GF and pathogenesis of PIH. Methods: Serum specimens were collected from 51 healthy pregnant women as a control group and 33 women suffered from PIH as third trimester of normal pregnancy(P＜0.001).There was a trend that serum levels of P1GF in PIH group decreased with the severity of PIH(P＜0.001).Conclusion:PlGF play important roles in placental angiogenesis throughout pregnancy, and decreased serum levels of PlGF is associated with PIH.
