Universal cervical‐length screening to prevent preterm birth in twin pregnancy: cost‐utility analysis

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 3, Page 290-297, September 2025.
ABSTRACT Objective The purpose of this cost‐utility analysis was to model the clinical and economic impact of three cervical‐length screening strategies among low‐risk twin pregnancies: two‐step universal screening (at 18–20 and 20–22 weeks), one‐step universal screening (at 18–20 weeks) and no screening.

不同内膜准备方案在子宫内膜异位症患者冻融囊胚移植中的疗效观察 [PDF]

, 2019
目的研究不同内膜准备方案对子宫内膜异位症(EMs)患者囊胚冻融移植(FET)妊娠结局的影响。方法回顾性分析EMs患者375个囊胚FET周期,按照子宫内膜准备方式分为:单纯人工周期组(HRT组,45个周期),促性腺激素释放激素激动剂降调节后人工周期组(GnRH-a+HRT组,121个周期)和自然周期组(NC组,209个周期)。比较3种内膜准备方案的囊胚FET妊娠结局。结果 3组EMs患者间年龄、不孕年限、基础抗苗勒管激素(AMH)和基础内分泌水平比较均无统计学差异(P>0.05 ...

Aspirin delays preterm birth in pregnancies at high risk for preterm pre‐eclampsia: evidence from randomized clinical trial in Asia

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 1, Page 24-32, July 2025.
ABSTRACT Objectives To investigate the impact of aspirin administration on the incidence of preterm birth, according to the type of delivery and gestational age at preterm birth, and to examine the hypothesis that aspirin delays preterm delivery. Methods This was a secondary analysis of a multicenter stepped‐wedge cluster randomized trial of a first ...

Automated multivolume placental reconstruction using three‐dimensional power Doppler ultrasound and infrared camera tracking

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 5, Page 624-632, May 2025.
ABSTRACT Objectives Placental insufficiency contributes to many obstetric pathologies, but there is no bedside clinical tool to evaluate placental perfusion. We have developed a method to acquire multiple three‐dimensional (3D) power Doppler (PD) ultrasound (US) volumes of placental vasculature, with infrared camera tracking of the precise spatial ...

子宫内膜异位症对冻融胚胎移植的影响 [PDF]

, 2019
目的探讨子宫内膜异位症(EMs)对冻融胚胎移植(FET)的影响。方法回顾性分析2015年1月至2017年12月EMs患者(A组,n=657)与盆腔输卵管因素不孕症患者(B组,n=3 271)解冻囊胚移植周期的临床和实验室指标。结果 A组患者年龄大于B组[(32.07±3.92)岁vs.(31.41±4.42)岁]、不孕年限大于B组[(5.05±2.86)年vs.(4.61±3.19)年],但差异无统计学意义(P>0.05)。两组内膜厚度[(9.97±1.81)mmvs.(9.69±1.75)mm ...

N‐terminal pro B‐type natriuretic peptide as biomarker to predict pre‐eclampsia and maternal–fetal complications

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 4, Page 447-455, April 2025.
ABSTRACT Objective A soluble fms‐like tyrosine kinase‐1 (sFlt‐1)‐to‐placental growth factor (PlGF) ratio cut‐off of 38 is currently considered optimal for ruling out pre‐eclampsia (PE); however, implementation of this ratio in clinical practice is limited.

性激素对妊娠期高血压的诊断价值分析

Zhongguo shiyan zhenduanxue, 2017
妊娠期高血压是严重威胁围产期母婴健康的产科综合征,临床上主要表现为高血压、蛋白尿和水肿等,给母婴带来严重的不良影响[1,2]。目前关于妊娠期高血压的确切的发病机制尚不明确,但其可能与母体内某些性激素的代谢紊乱有关[3,4]。因此,探索妊娠期高血压发病的相关生物分子对临床诊断和早期干预具有重要的意义。本研究分析性激素水平对妊娠期高血压的诊断价值,为临床诊断及评估和预测提供参考 ...
