摘要 目的分析子痫前期患者肾脏血流动力学参数与血管内皮损伤因子的相关性。方法选择产科住院分娩的子痫前期孕妇作为研究对象,分为轻度子痫前期组及重度子痫前期组,另选健康孕妇作为对照组。比较组间血清肾功能指标、肾动脉血流动力学参数及血管内皮损伤因子的差异,分析子痫前期患者肾动脉血流动力学参数与血管内皮损伤因子的相关性。结果轻度PE组及重度PE组尿素氮(BUN)、肌酐(Cr)、尿酸(UA)及肾脏血流动力学参数阻力指数(RI)、搏动指数(PI)、S/D高于对照组,舒张末期流速峰值(EDV)低于对照组,差异均有统计学意义(均P<0.05)。轻度PE组及重度PE组可溶性细胞内皮因子(sEng)、可溶性血管内皮生长因子受体(sFlt-1)、内皮素-1(ET-1)高于对照组,血管内皮生长因子(VEGF)低于对照组(均P<0.05);重度PE组血清可溶性细胞内皮因子(sEng)、可溶性血管内皮生长因子受体(sFlt-1)高于轻度PE组,VEGF低于轻度PE组(均P<0.05)。子痫前期肾脏血流动力学参数RI、PI及S/D与血清sEng、sFlt-1均呈正相关(均P<0.05),与VEGF均呈负相关(P<0.05),与ET-1均无相关性(P>0.05)。结论肾脏血流动力学参数可以作为筛查和评估子痫前期患者肾脏损伤的指标,血管内皮功能损伤可能是子痫前期患者肾脏损伤的机制之一。
