Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 4, Page 433-442, October 2025.
ABSTRACT Objective Currently, there are several surgical approaches to manage fetal open spina bifida (OSB), namely postnatal surgical repair, open fetal surgery and its minimally invasive alternative, fetoscopic repair. Our objective was to determine the optimal surgical approach for OSB, weighing the benefits and risks to the fetus and the pregnant ...

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.

Generation and Characterization of HCMV Specific Human Antibody to Explore Antibody Response Profile in HCMV Naturally Infected Individuals [PDF]

, 2015
人巨细胞病毒（Humancytomegalovirus，HCMV）是一种常见的疱疹病毒，在人群中普遍感染，儿童感染率约为10%-40%，成人为50%-90%，大部分感染者为无临床症状的健康人。但机体免疫功能低下的人群如器官移植患者及AIDS病人，更易发生HCMV病毒的新发或复发感染，引起致命疾病如肺炎、肝炎、脑炎等，从而导致器官移植失败及术后死亡；同时HCMV病毒也是宫内感染中危害最大的病毒之一，感染率占怀孕妇女的0.5%-2%，尤其是在发展中国家较为常见，孕妇感染后自身多无明显症状或轻微症状 ...

Is parvovirus B19 infection upsurge in 2023–2024 associated with adverse pregnancy outcome?

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 3, Page 307-313, September 2025.
ABSTRACT Objective A surge in parvovirus B19 infections has been reported in 2023–2024 across Europe and the USA, raising concerns about the associated perinatal risks. The aim of this study was to compare perinatal outcomes following maternal parvovirus B19 infection during the 2023–2024 period with those from a pre‐2023 cohort.

产前死胎危险因素的病例对照研究

Zhongshan Daxue xuebao. Yixue kexue ban, 2016
【目的】 探讨产前死胎的相关危险因素。【方法】 收集2011年1月-2015年12月中山大学附属第一医院收治的孕≥20周产前死胎病例74例作为死胎组，按1:2的比例随机选取同期148例单胎活产分娩作为对照组。回顾病例资料，比较两组的临床特点，分析产前死胎的危险因素。采用t检验、卡方检验及Logistic回归分析进行统计学处理。【结果】 无规范产检、流动人口、大专以下学历、胎动异常在死胎组的比率均高于对照组，两组相比差异均有统计学意义（P值分别为0.000、0.004、0.024、0.000），而年龄 ...

The establishment of Elispot-based neutralization assay for HCMV and its application in epidemiological study [PDF]

, 2013
人巨细胞病毒（humancytomegalovirus，HCMV）的感染在全球普遍存在。HCMV感染一般以潜伏状态存在，当机体免疫力低下时，则易发生再激发感染，引起严重甚至威胁生命的感染性疾病。在自然感染过程中，HCMV可感染包括淋巴细胞，上皮细胞以及内皮细胞在内的多种类型的细胞。HCMV体外培养体系的宿主细胞主要是上皮细胞及成纤维细胞。传统的基于细胞病变的TCID50以及空斑形成减少实验检测样本中和滴度的方法，存在周期长，操作繁杂，主观因素影响大的缺点，不适合大样本量的临床研究 ...

正弦曲线胎心率的预后和处理3例报告

Zhongshan Daxue xuebao. Yixue kexue ban, 1996
正弦曲线胎心率（ｓｉｎｕｓｏｉｄａｌｆｅｔａｌｈｅａｒｔｒａｔｅ，ＳＦＨＲ）的出现说明胎儿存在着严重的危险，是胎儿濒临死亡的征兆，围产儿死亡率高达５０％～７５％。１９９３年１月～１９９５年３月，我院对５８８６例次孕产妇进行胎儿电子监护产前无刺激试验（ＮＳＴ）或宫缩应激试验（ＣＳＴ）时，胎心率呈ＳＦＨＲ３例，无围产儿死亡。结合文献，分析了正弦曲线胎心率死亡的原因与合并症、分娩时机和方式的关系。作者认为及时终止妊娠，对不能短期内道自然分娩者，尽快手术产，可能降低围产儿的死亡率。
