NT超声检查技术联合孕中期四维彩超对胎儿结构畸形的诊断价值分析
Zhongguo shiyan zhenduanxue, 2019 目的分析胎儿颈项透明层厚度(NT)超声检查技术与孕中期四维彩超联合诊断胎儿结构畸形的价值。方法选取2016年2月至2018年3月我院产检产妇1205例,均予以产前二维彩超、NT超声检查联合孕中期四维彩超检查,对检查结果进行分析并随访至产后。结果孕11-14周1205例产检产妇中,确诊结构异常胎儿46例(3.82%),NT检出异常胎儿44例(3.65%);继续妊娠的1186例孕21-28周四维彩超检查中,确诊结构异常胎儿29例(2.45%),四维彩超检出异常胎儿29例(2.45 ...

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 2, Page 162-167, February 2026.ABSTRACT Objective Pre‐eclampsia (PE) is a leading cause of maternal and neonatal morbidity and mortality worldwide. Early identification of high‐risk pregnancies in the first trimester allows preventive treatment with low‐dose aspirin. This study aimed to evaluate whether multivariable Gaussian algorithm‐based PE screening strategies, with and without

Zhongguo 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 ...

, 1995 在胚胎发育早期，江豚上颌生有短须：左侧１－３根，右侧２－３根。具有半月形外耳廓。雄性胎儿阴茎露于体外。脐带较短。胎儿运动器官（胸鳍、尾鳍和尾柄）发育较快。随着胚胎的发育，外耳廓消失，阴茎藏于体腔。江豚胚胎发育过程中的这些形态学变化，再现了鲸类祖先在陆上生活的历史，同时也反映了鲸类在二次入水过程中所形成的对水环境的适应。此外。通过对收集的１７头江豚胎儿资料进行统计，结果表明长江江豚胎儿的生长速度约为９．０８ｃｍ／月（Ｏ．３０３ｃｍ／ｄ），妊娠期为９．４个月，交配季节为６－８月份，分娩为３ ...
