联合检测孕早期血脂指标、尿糖水平对妊娠期糖尿病及妊娠结局的预测价值研究

open access: yesZhongguo shiyan zhenduanxue, 2021
妊娠期糖尿病(GDM)是孕妇在妊娠期间发生或首次出现的糖代谢异常,其发病时间主要在孕中期及孕晚期。GDM患者在不同妊娠阶段中血清代谢物谱存在一定的差异,可能是鉴别GDM在不同妊娠阶段的潜在标志物,且其代谢差异主要表现磷脂代谢途径上[1-2]。研究表明[3],医学营养治疗中妊娠期糖尿病孕妇的依从度影响了母儿的妊娠结局,需改进营养指导,以增加其对医学营养治疗的依从性,从而改善妊娠期糖尿病孕妇的妊娠结局。近年来,GDM作为临床上常见的多发病,患病率也逐年升高,因此对于妊娠期糖尿病的关注也越来越高[4]。

Effect of sialic acid expression in maternal-fetal blood and tissues of natural and assisted reproductive technology’s pregnancy outcomes [PDF]

open access: yes, 2017
研究背景:唾液酸(Sialicacid,Sia)是一类以九碳糖神经氨酸为基本结构的衍生物的总称,在自然界广泛存在,并发挥重要的生物功能。N-乙酰神经氨酸(Neu5Ac),N-羟乙酰神经胺酸(Neu5Gc)和脱氨神经氨酸(KDN)是唾液酸三种主要亚型,其中,前两者是哺乳动物中最常见的存在形式,但在人体中很难检测到Neu5Gc。目前关于唾液酸的研究多集中于感染、肿瘤、冠心病、神经发育迟缓等疾病以及神经系统发育这方面的健康问题,它因广泛存在于人类的组织和体液包括血液、唾液、胃液、脑脊液 ...
