摘要: 目的:探讨脐带血和脐带血管肾上腺髓质素(ADM)和内皮素1(ET-1)在妊娠高血压综合征(简称妊高征)中的作用。方法:应用放射免疫法测定30例妊高征患者和12例正常妊娠晚期孕妇(简称正常晚孕组)脐静脉血浆ADM和ET-1水平,用免疫组化法检测ADM和ET-1蛋白在40例妊高征患者和12例正常妊娠晚期孕妇脐带血管中的表达。结果:①妊高征患者脐静脉血浆ADM水平高于正常晚孕妇女,且随着病情加重逐渐增高,中、重度妊高征患者与正常晚孕组比较差异也具有显著性(P<0.05)。妊高征患者脐静脉血浆ET-1水平略有升高,与正常晚孕组比较,差异无显著性(P>0.05);②正常晚孕组脐带血管内皮细胞和平滑肌细胞有ADM的表达,妊高征组随着病情加重,ADM表达增强;正常晚孕妇女ET-1在脐带血管的内皮细胞表达,妊高征组随着病情加重,ET-1表达减弱。 结论:脐血和脐带血管ADM和ET-1表达改变可能与妊高征胎儿胎盘之间血液循环调控有关。

Abstract: Objective To investigate the role of adrenomedullin (ADM) and endothelin-1 (ET-1) in the pathogenesis of pregnancy-induced hypertension (PIH). Methods The plasma concentrations of ADM in human umbilical vein of PIH patients(n=30) and normal late trimester pregnancy women (n=12)were measured by radioimmunoassay. The expressions of ADM and ET-1 in umbilical cord vessel of PIH patients(n=40)and normal late trimester pregnancy women (n=12) were detected by immunohistochemistry (SABC) . Results ①The plasma concentration of ADM in human umbilical vein of PIH patients was significantly higher than that of normal late trimester pregnancy women (P<0.05). The plasma concentration of ET-1 in human umbilical vein of PIH patients was similar to that of normal late trimester pregnancy women (P>0.05). ②The expression of ADM was found in endothelium and smooth muscle cell of umbilical cord vessel,and it increased with the serious degree of PIH. The expression of ET-1 was only found in endothelium of umbilical cord vessel, and it decreased with the serious degree of PIH. Conclusion The changes of ADM and ET-1 in umbilical cord plasma and vessel may related to regulation of fetoplacental circulation in PIH.
