Impact of race‐based customization on detection of fetal growth restriction
Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 4, Page 480-485, October 2025.ABSTRACT Objective Fetal growth standards determine which fetuses are diagnosed with fetal growth restriction (FGR) and become candidates for enhanced fetal monitoring. Given the existence of race‐based differences in fetal and neonatal weights, we sought to determine the impact of race‐based customization of fetal growth curves on the antenatal ...

联合检测VEGF以及PAPP-A在鉴别诊断先兆流产和异位妊娠中的价值
Zhongguo shiyan zhenduanxue, 2017 目的探讨联合检测血管内皮生长因子（VEGF）以及妊娠相关蛋白（PAPP-A）在先兆流产和异位妊娠鉴别诊断中的临床应用价值。方法选择宫内早孕患者60例（正常早孕组）、先兆流产患者50例（先兆流产组）以及异位妊娠患者40例（异位妊娠组）,检测并比较三组血清VEGF及PAPP-A水平。结果与正常早孕组比较,异位妊娠组和先兆流产组血清VEGF表达水平均显著的增高,PAPP-A表达水平显著降低,差异有统计学意义 ...

Zhongguo shiyan zhenduanxue, 2014 目前而言,异位妊娠发病率有升高趋势。异位妊娠需要及早诊断及早处理,改善患者预后。所以及时准确诊断是正确治疗的前提。虽然异位妊娠的诊断并不困难,可根据患者病史、体格检查、B超等仪器而确诊,但早孕5周前,B超并不能观察出胎心芽。为了探讨异位妊娠及早孕准确诊断,本文测定血清-HCG及孕酮值水平 ...
