诱导性多功能干细胞(induced human pluripotent stem cells,iPSC),也称诱导性多潜能干细胞,是利用特定基因或是特定基因产物(如蛋白质)诱导成体细胞重新编码,在一定条件下转化为类似胚胎干细胞(Embryonic Stem cell,ESC)的一类多潜能细胞。iPSC具有分化潜能,在体外能分化为拟胚体(embryonic bodies,EB),在动物体内能形成畸胎
最新2011AHA指南对大面积肺栓塞的定义:急性肺栓塞伴有持续性低血压(收缩压<90 mm Hg至少15min,排除非肺栓塞所致的心律失常、血容量不足、败血症或左室功能障碍)、症状性心动过缓(有休克症状或体征且心率<40次/min)。传统肺栓塞治疗包括抗凝、溶栓、外科手术等。大面积肺栓塞的单纯药物治疗效果有限;外科手术创伤大、出血多、难度大;介入治疗以其微创、可重复性及出血少的特点已成为治疗肺栓塞

近年来,肺血管疾病在学术领域发展迅速,随着认识的不断深入,疾病的分类和发病机理也逐渐清晰,相应的治疗手段也趋多样化和个体化。其中经导管介入治疗也已渗透到该领域。上海市胸科医院心内科报道了肺动脉分支血栓闭塞和肺静脉重度狭窄应用经皮球囊扩张和/或支架植入,取得良好疗效。
本文以原发性高血压合并IGT患者为研究对象,观察血清维生素D的变化,探讨维生素D与原发性高血压及并发IGT的相互关系。方法是:选取2011.07.26~2012.07.25在新疆医科大学第一附属医院住院的原发性高血压病的汉族患者216例,其中男性106例、女性110例,年龄(50.5±12.1)岁,记录身高、体重、入院SBP和DBP,检测其血清25-羟维生素D3、FPG、HbAlc、血脂和血钙等。
