An ultra-thin amniotic membrane preparation and its application as carrier in corneal epithelium tissue-engineering [PDF]

open access: yes, 2016
目的:羊膜是目前应用最广泛的构建组织工程角膜上皮的载体。但在临床应用中发现,基于羊膜构建的组织工程角膜上皮在移植术后角膜的透明度恢复并不理想。目前认为,羊膜基质的纤维细胞层及疏松的海绵层可能是影响羊膜透明度的主要原因。因此,本研究对传统去上皮羊膜(DAM)进行改造,制备一种新型的超薄羊膜(UAM)载体,并评估其生物学及光学性质,同时探讨使用该种载体构建组织工程角膜上皮的可行性。 方法:本研究利用0.02%的EDTA去除失活羊膜组织的上皮细胞,并采用IV型胶原酶消化去除羊膜基质的纤维层及海绵层 ...

Comparison of open fetal, fetoscopic and postnatal surgical repair for open spina bifida: decision analysis

open access: yesUltrasound 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 ...

孕妇血型IgG抗体效价与新生儿溶血病发病率关系的分析

open access: yesZhongguo shiyan zhenduanxue, 2015
新生儿溶血病(hemolytic disease of the newborn,HDN)是因母胎红细胞血型不合,母体的免疫系统被胎儿红细胞致敏而产生血型IgG类抗体,这种血型IgG类抗体可以通过胎盘进入胎儿的血液循环,胎儿的红细胞被母亲的IgG血型抗体包被,并在婴儿的单核巨噬细胞系统内受到破坏而引起的免疫性溶血性疾病[1]。溶血出现后继发引起胎儿或新生儿发生贫血、肝脾肿大等症状 ...

Impact of race‐based customization on detection of fetal growth restriction

open access: yesUltrasound 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 ...

四维超声联合高分辨血流成像在胎儿肺静脉观察中的应用

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2017
摘要:【目的】探讨四维超声联合高分辨血流成像(HD flow)在观察胎儿肺静脉中的应用价值。【方法】本研究纳入 2015年6月-2016年6月在我院接受产前胎儿心脏超声检查的胎儿130胎。于胎儿四腔心切面分别应用彩色多普勒和高分 辨血流成像观察并计数肺静脉的显示数目。在开启HD flow状态下,于胎儿四腔心切面采集心脏三维容积数据,利用图像 后处理软件对容积数据分析重建,获取胎儿肺静脉的三维图像,观察并计数肺静脉的显示数目。对比三种方法对正常125 例胎儿肺静脉的显示情况 ...
