随着无偿献血的深入开展,各地血站为了降低血液不合格报废率,越来越重视献血前筛查工作,但对ALT的筛查各血站都在寻找适合自己血站的方法,存在较多差异,有的血站不筛查,有的用干式生化,有的用半自动生化,今年年初我站提出加强献血前ALT的筛查,特别是筛查要符合工作流程的需要,选择的方法简单又能有效解决ALT筛查问题,降低因ALT不合格的血液报废率,为此我们进行了一些比较,选择了艾康公司的Mission干式生化,

目的研究不同检验方法在RhD弱表达变异体中的应用范围及相互之间的关系。方法应用酶介质法和间接抗球蛋白试验(indirect antiglobulin test,IAT)在盐水凝集法初筛出的RhD阴性个体中进一步筛查弱D/部分D,然后在IAT确认的RhD阴性个体中采用吸收放散试验筛查DEL型。结果 278例RhD阴性个体酶介质法和IAT分别筛查出13和15例弱D/部分D,吸收放散试验筛查出64例DEL型。结论在这几种RhD弱表达变异体筛查方法中,盐水凝集法不能筛查RhD弱表达变异体 ...

Effects of Treponema pallidum on THP-1 derived macrophage polarization [PDF]
梅毒螺旋体(Treponemapallidum)是性传播疾病梅毒的致病菌,尽管有关T.pallidum的研究已经开展近一个多世纪,对其生物学及病原学特性有了一定的了解,然而对于T.pallidum致病机制的认识还处于起步阶段。巨噬细胞作为机体防御外来病原体的第一道防线,在对T.pallidum的识别、吞噬、抗原提呈、杀伤等方面均发挥着重要作用。随着对巨噬细胞研究不断深入,有学者将巨噬细胞分为两种不同的极化类型,即促进炎症发展的M1型巨噬细胞和在抑制炎症反应及组织修复等方面发挥作用的M2型巨噬细胞 ...

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.

目的分析五横切面检查法在胎儿心脏畸形产前筛查中的应用效果。方法从2012年7月-2015年7月我院收治的产前常规检查孕妇中,抽取5500例采用五横切面筛查法的产妇作为研究对象。比较五横切面检查结果和产后或尸检确诊结果,并计算五横切面筛查的准确性。结果在5500例孕妇中,五横切面筛查检出胎儿心脏畸形34例,检出率为0.62%。其中17例孕妇正常妊娠、16例引产、1例胎儿死亡,经产后或尸检确诊。胎儿经产后或尸检确诊显示,五横切面筛查漏诊4例、误诊3例。计算可知阴性预测值为5469/5473=99.9 ...
