Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 4, Page 470-479, October 2024.ABSTRACT Objectives Our aim was to examine the prenatal profiles of pregnancies affected by an atypical chromosomal aberration, focusing on pathogenic copy‐number variants (pCNVs). We also wanted to quantify the performance of combined first‐trimester screening (cFTS) and a second‐trimester anomaly scan in detecting these aberrations. Finally, we aimed

Zhongguo shiyan zhenduanxue, 2015 心血管疾病是严重危胁人类健康和生命的常见病和多发病,已成为人类死亡的第一位原因。特发性生长激素缺乏症（IGHD）的儿童由于生长激素（GH）缺乏引起身材矮小,高胆固醇或高脂血症等代谢紊乱[1]。因此这些患儿有潜在发生心血管疾病的危险,影响儿童的身心健康。近几年国外文献报道,继发于垂体肿瘤放疗或手术后的成年人GHD患者心血管疾病的发生率明显高于正常对照组 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2017 血管新生是肿瘤发生发展中一个重要的病理特征，抗血管新生已经成为肿瘤治疗研究的一大热点。目前抗 血管新生的策略主要是应用血管新生刺激因子拮抗剂或血管新生抑制因子，以恢复肿瘤中被打破的血管新生平衡。相比 于血管新生刺激因子拮抗剂，内源性血管新生抑制因子展现了更好的治疗前景，但是其分子机制还有待进一步阐明。内 源性血管新生抑制因子包括两类，一类是前体蛋白的水解片段，如人纤溶酶原K5（plasminogen kringle 5，K5）、血管抑素 （angiostatin/ kringle 1-4 ...

Prenatal diagnosis and postnatal outcome of Type‐III vasa previa: systematic review of literature
Ultrasound in Obstetrics &Gynecology, Volume 63, Issue 1, Page 24-33, January 2024.ABSTRACT Objective Type‐III vasa previa (VP) is a rare form of VP, not necessarily associated with other placental or vascular anomalies, in which aberrant vessels run from the placenta to the amniotic membranes, near the internal cervical os, before returning to the placenta. Early diagnosis of Type‐III VP is important but technically challenging. The

Effects of Bone Mesenchymal Stem Cells Transplantation Combined with Therapeutic Mild Hypothermia on Recovery of Neurological Functions and Its Mechanisms in Cerebral Ischemia Injury in Rats [PDF]
, 2017 摘要 研究背景和目的： 缺血性脑卒中是导致人类高致死率和致残率的主要疾病之一，至今仍缺乏真正有效的治疗措施。研究表明，通过移植BMSCs(bonemarrowmesenchymalstemcell)可缩小梗死面积，促进神经功能修复。亚低温（32～35℃）治疗可减小梗死灶体积，促进血管再生，减轻脑水肿，促进神经功能恢复。因此，本课题组联合这两种治疗方案以期获得最大治疗效果，为临床上脑血管疾病的治疗提供丰富的理论依据。 研究内容和方法： 采用密度梯度离心法与全骨髓细胞贴壁法相结合，提取、培养 ...
