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热浸镀锌超高强钢板钒微合金化技术研究显示文摘对超高强度钢板进行热处理,模拟热浸镀锌和合金化镀锌工艺的热循环,并考察获得的力学性能和微观组织。研究用钢含有适量的碳(~0.2%)、锰(1.2%)和铬(0.4%),保证钢板在奥氏体化后在镀锌前的连续退火线上进行快速冷却时能够完全转变成马氏体。采用不同的钒含量(0~0.1%)和氮含量(0.002%~0.012%),研究这些微合金化元素对回火马氏体强度的影响。尤其与高氮相配合情况下,钒有助于抵抗回火效应,因此在镀锌后大部分原始强化贡献被保留下来,使得钢的抗拉强度超过1 000 MPa。使用铝或硅进行不同脱氧试验,发现在同一碳含量下两者具有相同的强度水平,但是Si镇静钢的弯曲性能明显优异。对退火钢板进行微观组织观察,但是钒产生有益作用的原因还未完全掌握。通过研究得出这样结论:钒微合金化对耐腐蚀超高强度钢板的开发而言是一种极具前景的途径。Hutchinson B Martin D Karlsson O Lindberg F Thoors H Marceau R K W Taylor A S 2016钢铁钒钛2016,37,6:2
