子痫前期患者胎盘组织PLGF表达及血清HGF和VEGF测定

目的：探讨子痫前期患者血清肝细胞生长因子（HGF）、胎盘生长因子（PLGF）表达水平和血管内皮生长因子（VEGF）水平的变化及意义。方法：分别采用放射免疫分析、酶联免疫分析和免疫组化法测定32例子痫前期孕妇（子痫前期组）和35名正常孕妇（对照组）血清VEGF、HGF和PLGF表达水平。结果：子痫前期患者无论轻度子痫前期组和重度组血清HGF含量均显著低于对照组（P均〈0.01）;但轻度和重度组之间水平无显著性差异（P〉0.05）。胎盘中PLGF表达水平也显示轻度和重度两组均显著低于对照组（P均〈0.01）;且重度组又显著低于轻度组（P〈0.01）。血清VEGF水平轻度组显著低于对照组（P〈0.05）;重度组水平较对照组降低更为显著（P〈0.01）,且重度组显著低于轻度组（P〈0.01）。相关分析显示,HGF含量与PLGF具有显著相关性（r=0.6012,P〈0.01）;而与VEGF水平则无明显相关性（r=0.3010,P〉0.05）。结论：测定结果证实,患者血清三项标志物均参与了子痫前期的病理进程,其测定对于了解病情和预后评估有帮助。

Clinical Significance of Changes of Serum VEGF,HGF Levels and Placental Tissue PLGF Expression in Patients with Pre-eclampsia

Objective To explore the clinical significance of changes of serum levels of hepatocyte growth factor (HGF),vascular endothelial growth factor (VEGF) and placental tissue expression of placenta growth factor (PLGF) in patients with pre-eclampsia. Methods Serum HGF (with ELISA),VEGF (with RIA) and placental tissue expression of PLGF (with immuno-histochemistry) were examined in 15 patients with mild pre-eclampsia,17 patients with severe pre-eclampsia and 35 normal pregnant women (as controls). Results The se...
