Fetoscopic laser ablation vs standard management for Type‐II and Type‐III vasa previa
Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 320-328, March 2026.ABSTRACT Objective The standard management (SM) for vasa previa (VP) includes antepartum inpatient admission at 28–32 weeks' gestation followed by Cesarean delivery at 34–37 weeks. Case reports and case series have reported on fetoscopic laser ablation (FLA) as an alternative management approach for Types‐II and ‐III VP.

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 ...

Rapid prenatal diagnosis of chromosomal aneuploidy using real-time multiplex ligation-dependent probe amplification （real-time MLPA） [PDF]
, 2008 染色体非整倍体是一类发病率高，病征严重的遗传性疾病。对于大多数此类病征目前尚无有效治疗的手段。因此，快速、准确、高通量地对染色体非整倍体进行产前诊断对于减少患病胎儿的出生、提高人口素质具有十分重要的意义。本论文运用实时荧光多重探针连接再扩增技术以及相关的数据分析方式，致力于实现对染色体非整倍胎儿的快速产前诊断。 第一章，综述了染色体非整倍体的产前诊断现状，介绍了传统细胞生物学诊断方法以及新兴分子生物学诊断方法的技术特点与应用现状。针对目前分子生物学产前诊断技术的优缺点 ...

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 2, Page 200-209, August 2025.Abstract Objectives Neonates with critical congenital heart disease (CCHD) are at risk for adverse early brain development and long‐term neurodevelopmental sequelae. Insulin‐like growth factor‐1 (IGF‐1) and insulin‐like growth factor binding protein‐3 (IGFBP‐3) are essential contributors to brain growth and maturation.

Complete androgen insensitivity syndrome, a pedigree gene mutation analysis [PDF]
, 2016 研究背景 雄激素不敏感综合征（AndrogenInsensitivitySyndrome，AIS），是一种常见的男性假两性畸形。是伴X连锁隐性遗传病。患者染色体核型为46，XY，但其X染色体上的雄激素受体（Androgenreceptor，AR）基因存在缺陷，可致雄激素靶器官上的AR出现缺陷，体内的雄激素不能发挥相应的作用而出现相应的临床症状。此疾病可对患者的生殖能力造成不同程度的影响，还可能引发与性发育异常相关的性心理、性行为的异常，并可能给社会和患者家庭造成难以挽回的损失 ...
