1Fondaparinux预防老年急性内科患者发生静脉血栓形成的效果与安全性:随机安慰剂对照研究显示文摘目的:观察 Fondaparinux 对具有中高度静脉血栓发生危险的老年急性内科住院患者的抗凝效果与安全性。设计:双盲随机安慰剂对照研究。背景:8个国家的35个中心。参与者:849例≥60岁内科患者,住院原因分别为充血性心力衰竭、慢性肺病合并急性呼吸系统疾患、急性炎症性或感染性疾病,预期至少住院4天以上。干预:2.5 mg Fondaparinux 或安慰剂,每天1次皮下注射,持续6~14天。观察指标:主要指标为静脉血栓形成(治疗后15天内采用双侧静脉造影检查)及有症状的静脉血栓;次要指标为死亡与出血。患者随访时间为1个月。结果:Fondaparinux 治疗组425例患者和安慰剂组414例患者接受了安全性分析(10例未治疗)。644例患者(75.9%)可接受主要指标分析。静脉血栓检出率在 Fondaparinux 治疗组为5.6%(18/321),安慰剂组为10.5%(34/323),相对危险减少46.7%(95% CI 7.7%~69.3%)。安慰剂组5例患者发生有症状的静脉血栓,Fondaparinux治疗组无患者发生有症状的静脉血栓(P=0.029)。两组均有1例(0.2%)患者发生严重出血。随访结束时,安慰剂组、Fondaparinux 治疗组分别死亡25(6.0%)、14(3.3%)例患者。结论:Fondaparinux 可有效预防急性内科老年患者无症状性及有症状的静脉血栓。严重出血几率两组相似。Alexander T Cohen Bruce L Davidson Alexander S Gallus Michael R Lassen Martin H Prins Witold Tomkowski Alexander G G Turpie Jan F M Egberts Anthonie W A Lensing 石汉平(译) 王深明(校) 2006英国医学杂志中文版2006,9,5:3
2菱面体畸变的钙钛矿结构多铁性氧化物薄膜畴界精细结构显示文摘畴是所有铁性材料的一个共同本质特性,畴及畴界的结构极大影响着材料性能。本文应用高分辨透射电子显微学和定量电子显微学,在原子尺度定量研究了钙钛矿菱面体结构多铁性薄膜BiFeO3的109°畴界的精细结构,包括畴界附近阳离子位移及局部铁电极化分布。结果表明:正是由于畴界附近原子发生微小位移,导致材料能带的变化,带隙减小,从而在绝缘BiFeO3中产生独特的导电性能。这不仅为研究铁电极化反转和磁电效应等科学问题提供关键的定量结构信息,同时也促进相关材料的设计和性能优化。詹倩 于荣 CHU Y H MARTIN L W RAMESH R 2010电子显微学报2010,29,5:2
