1Severe acute pancreatitis: Clinical course and management显示文摘Severe acute pancreatitis (SAP) develops in about 25% of patients with acute pancreatitis (AP). Severity of AP is linked to the presence of systemic organ dysfunctions and/or necrotizing pancreatitis pathomorphologically. Risk factors determining independently the outcome of SAP are early multi-organ failure, infection of necrosis and extended necrosis (> 50%). Up to one third of patients with necrotizing pancreatitis develop in the late course infection of necroses. Morbidity of SAP is biphasic, in the first week strongly related to early and persistence of organ or multi-organ dysfunction. Clinical sepsis caused by infected necrosis leading to multi-organ failure syndrome (MOFS) occurs in the later course after the first week. To predict sepsis, MOFS or deaths in the first 48-72 h, the highest predictive accuracy has been objectified for procalcitonin and IL-8; the Sepsis- Related Organ Failure Assessment (SOFA)-score predicts the outcome in the first 48 h, and provides a daily assessment of treatment response with a high positive predictive value. Contrast-enhanced CT provides the highest diagnostic accuracy for necrotizing pancreatitis when performed after the first week of disease. Patients who suffer early organ dysfunctions or at risk of developing a severe disease require early intensive care treatment. Early vigorous intravenous fluid replacement is of foremost importance. The goal is to decrease the hematocrit or restore normal cardiocirculatory functions. Antibiotic prophylaxis has not been shown as an effective preventive treatment. Early enteral feeding is based on a high level of evidence, resulting in a reduction of local and systemic infection. Patients suffering infected necrosis causing clinical sepsis, pancreatic abscess or surgical acute abdomen are candidates for early intervention. Hospital mortality of SAP after interventional or surgical debridement has decreased in high volume centers to below 20%.Hans G Beger Bettina M Rau 2007World Journal of Gastroenterology2007,13,38:122
2高使用性能粉末冶金零件的表面致密化显示文摘为保证机构的可靠性,历史上一直在用锻钢合金批量生产高转矩变速器零件,诸如变速器齿轮、高性能链轮、单向离合器座圈及滚珠轴承座圈。虽然用粉末冶金工艺生产的零件成本低廉,但常规粉末冶金钢的静态、疲劳及耐磨性能的局限性,使粉末冶金零件不能应用于上述领域。为解决这些缺欠,近年来,一直在研发用选择性表面致密化(SSD)改进粉末冶金钢性能的各种生产工艺。特别是,PMG集团开发出了一种拥有专利权的表面致密化工艺——DensiForm。利用这种工艺可使零件表面关键部分形成深度达1mm的完全致密化表面层,而零件心部仍然是多孔性的。这种结合与粉末冶金材料合金化的灵活性,使生产的烧结钢零件的使用性能可与在高应力下使用的锻钢性能相比拟。本文将介绍2个例子,即变速器中应用的表面致密化螺旋齿轮和直齿链条的驱动链轮。本文说明了螺旋齿轮和驱动链轮的生产工艺与显微组织,介绍了轿车变速器用螺旋齿轮的性能(其中包括在三轴总成的成对试验台架上得到的滚动接触疲劳的数据)和表面致密化链轮的材料性能与使用性能。Lorenz S Sigl Günter Rau Christian Dennert 2012粉末冶金技术2012,30,2:4
3表面致密化粉末冶金齿轮的性能显示文摘用压制、烧结及选择性横向辗压表面致密化制造了轿车变速器的粉末冶金螺旋齿轮。在生产的每一道工序中都根据显微组织、齿轮几何形状、表面粗糙度及DIN品质对齿轮的性能演变进行了监控。将粉末冶金齿轮的几何形状和现在变速器中使用的常规生产的锻钢齿轮(DIN品质7)进行了比较。表明,制造的粉末冶金齿轮的品质位于DIN品质8范围以内;而且,证明通过生产工序的改变可减小对中与齿廓的误差。虽然锻钢齿轮的对中与齿廓误差较小,但是粉末冶金齿轮的偏心率与节矩的误差和表面粗糙度较好。Lorenz S.Sigl Günter Rau Michael Krehl 韩凤麟(译) 2012粉末冶金技术2012,30,3:4

5同步器系统的粉末冶金零件显示文摘近年来,手动变速器的同步器系统中的关键零件,诸如同步器齿毂与同步器锁环,都在用粉末冶金工艺大量生产。本文首先介绍近年来生产先进同步器齿毂用的高强度粉末冶金钢;然后对碳纤维、烧结摩擦层及Mo丝喷涂衬面3种同步器锁环用摩擦衬面进行了比较,根据压力与滑动速度讨论了其摩擦性能与寿命长短;最后,特别强调了粉末冶金的新发展,诸如滑动齿套与负载齿轮,给出并讨论了滑动齿套的应用试验结果,阐述了表面致密化螺旋齿轮的使用性能,给出了运转-时间试验的结果,并和常规的锻钢齿轮进行了比较。Lorenz S Sigl Günter Rau 韩凤麟(译) 2013粉末冶金技术2013,31,2:2
