| 2 | 高性能粉末冶金材料发展及其解决方案显示文摘与其它制造技术相比,粉末冶金技术可以更经济和高效地生产结构部件,并能达到高的尺寸精度和性能需求,这一优势一直驱动着粉末冶金技术的发展。粉末冶金技术为了能够适应汽车工业不断发展的应用需求,迫切需要开发具有更高尺寸精度、更高性能以及经济高效的粉末冶金材料解决方案,粉末冶金技术可以通过不同的工艺路径来实现这一目标。例如开发经济的新型合金体系,实现更高密度的新型压制技术,结合高温烧结和快速冷却的烧结工艺,以及碳势控制和二次热处理等工艺,都是可行的解决方案,单独或组合采用这些工艺都可以提高材料性能。随着人们对可持续发展越来越重视,选择对环境影响最小的材料和制造工艺变得尤为重要。本文探讨了满足性能要求的金属粉末方案和工艺条件等关键因素,并列举了具有成本效益和可持续性的汽车应用案例,如同步轮毂,凸轮轴桃片,链轮,齿轮等高要求的应用。 | 谭兆强 Ulf Engström 苏鹏飞 李昆 刘咏 | 2020 | 粉末冶金工业2020，30，3： | 10 |
| 3 | 粉末冶金钢中的Cu显示文摘近年来,粉末冶金已成为一种可制造形状结构复杂、精度高及具有优异力学性能的零件的重要且成本可行的生产工艺。在铁基粉末冶金产品中,除碳外,Cu是应用最广的一种合金化元素。虽然Cu在锻轧钢中具有不良作用,但在粉末冶金钢中却具有显著强化作用。然而,Cu在烧结中会引起胀大,并且在与Fe粉的混合粉中倾向于偏聚,从而导致压坯的各部分组成之间发生变化,致使烧结件的尺寸显著分散。通过不同的方法将Cu粉粘结于Fe粉颗粒上,可有效地防止这种偏聚。本文评定了用不同的含Cu合金化系统得到的零件力学性能与尺寸变化。 | Ulf Engstrm 韩凤麟 | 2012 | 粉末冶金技术2012，30，6： | 6 |
| 4 | Impact of body composition on survival and morbidity after liver resection in hepatocellular carcinoma patients显示文摘Background: Hepatocellular carcinoma is the most common innate liver tumor. Due to improved surgical techniques, even extended resections are feasible, and more patients can be treated with curative intent. As the liver is the central metabolic organ, preoperative metabolic assessment is crucial for risk stratification. Sarcopenia, obesity and sarcopenic obesity characterize body composition and metabolic status. Here we present the impact of body composition on survival after liver resection in patients with hepatocellular carcinoma. Methods: A retrospective database analysis of 70 patients who were assigned for liver resection due to hepatocellular carcinoma was conducted. For assessment of sarcopenia and obesity, skeletal muscle surface area was measured at lumbar vertebra 3 level(L3) in preoperative four-phase contrast enhanced abdominal CT scans, and L3 muscle index and body fat percentage were calculated. Results: Univariate analysis comparing the survival curves using the score test demonstrated superior postoperative overall survival for sarcopenic( P = 0.035) and sarcopenic obese( P = 0.048) patients as well as a trend favoring obese( P = 0.130) subjects. Whereas multivariate analysis could not identify significant difference in postoperative survival regarding sarcopenia, obesity or sarcopenic obesity. Only large tumor size, multifocal disease and male gender were risk factors for long-term survival. Conclusions: Sarcopenia, obesity and sarcopenic obesity are indeed no risk factors for poor postoperative survival in this study. Our data do not support the evaluation of sarcopenia, obesity and sarcopenic obesity before liver resection in hepatocellular carcinoma patients. | Andreas Kroh Diane Uschner Toine Lodewick Roman M Eickhoff Wenzel Sch?ning Florian T Ulmer Ulf P Neumann Marcel Binneb?sel | 2019 | Hepatobiliary & Pancreatic Diseases International2019，18，1： | 5 |
| 5 | Lactobacilli,bifi dobacteria and E.coli nissle induce pro-and anti-inflammatory cytokines in peripheral blood mononuclear cells显示文摘AIM: To investigate whether the stimulation of peripher- al blood mononuclear cells (PBMNC) with the cell debris and cell extraction of different probiotic strains is similar or species specifi c. METHODS: Three strains of bifi dobacteria, 4 strains of lactobacilli, and E. coli nissle were sonicated and centri- fuged in order to divide them into cell extract and cell debris. PBMNC were separated by density gradient and incubated for 36 h with either the cell debris or the cell extract of single strains of probiotic bacteria in doses from 102 to 108 CFU/mL. Cell supernatants were taken and interleukin (IL)-10, IL-1β, and tumor necosis factor (TNF)-α were determined by ELISA. RESULTS: Depending on the species super-family, the strains had different stimulation patterns. Except for both L. casei strains, the cell extract of bifidobacteriaand lactobacilli had less stimulating capacity than cell debris, whereas the cell extract of E. coli nissle had simi- lar stimulating properties to that of the cell debris of the strain and significantly more stimulating capacity than that of bifi dobacteria and lactobacilli. The cell debris of bifi dobacteria stimulated more cytokine release than the cell debris of lactobacilli. The cell debris of lactobacilli did not have a stimulating capacity when lower concentra- tions were used. Neither cell extraction nor cell debris had an inhibitory effect on the production of the tested cytokines by stimulated PBMNC. CONCLUSION: The incubation of probiotic strains, which have been used in clinical trials for inflammatory diseases, with immunocompetent cells leads to different species specifi c reactions. High IL-10 response to cell de- bris of bifi dobacteria and E. coli nissle can be found. This corresponds to positive effects of bifi dobacteria and E. coli nissle in clinical trials for inflammatory bowel disease compared to negative outcomes obtained with lactoba- cilli. | Ulf Helwig Karen M Lammers Fernando Rizzello Patricia Brigidi Verena Rohleder Elisabetta Caramelli Paolo Giochetti Juergen Schrezenmeir Ulrich R Foelsch Stefan Schreiber Massimo Campieri | 2006 | World Journal of Gastroenterology2006，12，37： | 3 |
| 6 | The European registry of quality outcomes for cataract and refractive surgery(EUREQUO):a database study of trends in volumes,surgical techniques and outcomes of refractive surgery显示文摘Background:A European web-based registry for refractive surgery was established in 2008;The European Registry of Quality Outcomes for Cataract and Refractive Surgery(EUREQUO).The aim of the registry was to improve treatment and standards of care for refractive surgery.Further aims were to offer a tool for benchmarking by establishing a reference database and for surgeons to enter and analyze their own outcomes.The purpose of this study was to characterize the registry and analyze the data collected during its first decade.Methods:The characteristics of the web-based registry are described.Data collected from February 4^(th) 2004 until June 30th 2014 are included in the analysis.The database is analyzed in terms of surgical technique,indications for surgery,complications,and refractive and visual outcomes.Results:Data have been reported from 47 centers in 14 countries until mid-2014.About 4,000 procedures were reported annually.The most frequent procedure was laser-assisted in-situ keratomileusis(LASIK)with 11697 reported surgeries.Over time in the database,LASIK declined(p<0.001)while photorefractive keratectomy(PRK)and refractive lens exchange(RLE)increased(p<0.001 for both procedures).The indications for surgery,in terms of preoperative refraction and age,were stable over time,for all types of procedures.Surgical complications were reported infrequently and with a well-known relationship to the type of surgical procedure.The reported refractive outcomes were good.The visual outcomes indicate a significant increase of visual acuity after high myopia treatment by phakic intraocular lens in the anterior(phakic IOL AC)and the posterior(phakic IOL PC)chamber and a poorer visual outcome,after both myopia and hyperopia treatment,by epithelial LASIK(Epi-LASIK).Conclusions:We describe the establishment of a European registry for refractive surgery.The database increases at a rate of approximately 4000 refractive procedures per year.The most frequent procedure is LASIK,but both PRK and RLE are an increasing part of the reported procedures.The indications for surgery have been stable over time.Surgical complications and visual outcome vary,depending on the type of surgery. | Mats Lundström Sonia Manning Peter Barry Ulf Stenevi Ype Henry Paul Rosen | 2015 | Eye and Vision2015，2，1： | 3 |
