磁性纳米复合粒子富集胎儿细胞在无创性产前诊断22q11.2微缺失综合征中的应用
目的探讨利用磁性纳米复合粒子富集胎儿细胞进行无创性产前诊断22q11.2微缺失综合征的可行性。方法收集研究对象26例,分别经过磁性纳米粒子富集胎儿有核红细胞(研究组)及羊水穿刺胎儿细胞(对照组)进行荧光原位杂交(FISH)检测确定22q11.2是否存在异常,比较两组之间存在的差异。结果两组在诊断22q11.2微缺失综合征方面一致率为100%(2/2),证实了利用该方法实现无创性产前诊断22q11.2微缺失综合征的可行性。结论磁性纳米复合粒子富集胎儿细胞诊断22q11.2微缺失综合征为无创性的产前诊断 ...

Routine 36‐week scan: prediction of small‐for‐gestational‐age neonate
ABSTRACT Objectives First, to compare the predictive performance of routine ultrasonographic estimated fetal weight (EFW) at 31 + 0 to 33 + 6 and 35 + 0 to 36 + 6 weeks' gestation for delivery of a small‐for‐gestational‐age (SGA) neonate. Second, to compare the predictive performance of EFW at 36 weeks' gestation for SGA vs fetal growth restriction ...

ABSTRACT Objective Accurate differentiation between placenta accreta spectrum (PAS) and uterine‐scar dehiscence with underlying non‐adherent placenta is often challenging, even for PAS experts, both prenatally and intraoperatively. We investigated the use of standardized two‐dimensional grayscale ultrasound and Doppler imaging markers in ...
