Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 6, Page 749-760, June 2025.ABSTRACT Objective Placental dysfunction can result in small‐for‐gestational age (SGA) or fetal growth restriction (FGR). The aim of this prospective cohort study was to assess the association of the cerebroplacental ratio (CPR) and other more conventional fetoplacental Doppler indices, circulating placental growth factor (PlGF) levels and soluble fms ...

孕妇血清妊娠相关蛋白-A及超敏C反应蛋白在子痫前期临床检测意义分析
Zhongguo shiyan zhenduanxue, 2014 目的探讨孕妇血清妊娠相关蛋白-A及超敏C反应蛋白在子痫前期的临床检测意义。方法选择我院2010年7月至2013年7月期间收治的子痫前期患者共221例,上述患者根据子痫前期严重程度分为轻度子痫前期共144例,重度子痫前期患者共77例,分别作为轻度组和重度组。同时选择在我院定期产前检测的正常孕妇50例,作为对照组。采用酶联免疫吸附实验测定血清妊娠相关蛋白A水平;采用免疫发光法测定超敏C反应蛋白水平。结果重度组和轻度组的血清超敏C反应蛋白、妊娠相关蛋白A水平分别高于对照组,差异有统计学意义 ...

孕妇外周血中高甲基化RASSF1A基因检测对子痫前期早期预测价值的研究
Zhongguo shiyan zhenduanxue, 2019 目的通过分析子痫前期孕妇外周血中胎儿高甲基化RASSF1A基因含量的变化,探讨孕妇外周血中胎儿游离DNA水平在子痫前期中的预测诊断价值。方法收集子痫前期孕妇外周血样本32例,择同期孕龄健康孕妇30例为对照组,采用荧光定量PCR法检测孕妇外周血中高甲基化RASSF1A基因的含量,应用受试者工作特征曲线(ROC)评价高甲基化RASSF1A基因检测对轻度和重度子痫前期孕妇的诊断价值。结果轻度子痫前期组和重度子痫前期组孕妇血浆高甲基化RASSF1A基因的中位数倍值分别是正常妊娠孕妇的3.28倍和10.47倍 ...
