| 1 | 新的铝锡硅发动机轴承合金显示文摘介绍一种用于发动机轴承的AlSn8Si2.5Pb2CuO.8Cr0.2新合金。专门开发的这种合金优化了抗咬合性,同时,又提供了极好的抗疲劳性和耐磨性。该合金的开发系利用高冷却率铸轧工艺的优点,并采用高温下把合金复于钢背上的粘结工艺。列出新合金的性能参数,包括抗疲劳、抗咬合特性及耐磨性,此数据包含与淬硬钢、球铁、软钢三种不同材料配对的抗咬合数据。 | Whitney W J 孙杰 张乐山 | 2000 | 国外内燃机2000，32，2： | 13 |
| 2 | Operative complications and economic outcomes of cholecystectomy for acute cholecystitis显示文摘BACKGROUND Recent management of acute cholecystitis favors same admission(SA)or emergent cholecystectomy based on overall shorter hospital stay and therefore cost savings.We adopted the practice of SA cholecystectomy for the treatment of acute cholecystitis at our tertiary care center and wanted to evaluate the economic benefit of this practice.We hypothesized that the existence of complications,particularly among patients with a higher degree of disease severity,during SA cholecystectomy could negate the cost savings.AIM To compare complication rates and hospital costs between SA vs delayed cholecystectomy among patients admitted emergently for acute cholecystitis.METHODS Under an IRB-approved protocol,complications and charges for were obtained for SA,later after conservative management(Delayed),or elective cholecystectomies over an 8.5-year period.Patients were identified using the acute care surgery registry and billing database.Data was retrieved via EMR,operative logs,and Revenue Cycle Operations.The severity of acute cholecystitis was graded according to the Tokyo Guidelines.TG18 categorizes acute cholecystitis by Grades 1,2,and 3 representing mild,moderate,and severe,respectively.Comparisons were analyzed withχ2,Fisher’s exact test,ANOVA,ttests,and logistic regression;significance was set at P<0.05.RESULTS Four hundred eighty-six(87.7%)underwent a SA while 68 patients(12.3%)received Delayed cholecystectomy.Complication rates were increased after SA compared to Delayed cholecystectomy(18.5%vs 4.4%,P=0.004).The complication rates of patients undergoing delayed cholecystectomy was similar to the rate for elective cholecystectomy(7.4%,P=0.35).Mortality rates were 0.6%vs 0%for SA vs Delayed.Patients with moderate disease(Tokyo 2)suffered more complications among SA while none who were delayed experienced a complication(16.1%vs 0.0%,P<0.001).Total hospital charges for SA cholecystectomy were increased compared to a Delayed approach($44500±$59000 vs$35300±$16700,P=0.019).The relative risk of developing a complication was 4.2x[95%confidence interval(CI):1.4-12.9]in the SA vs Delayed groups.Among eight patients(95%CI:5.0-12.3)with acute cholecystitis undergoing SA cholecystectomy,one patient will suffer a complication.CONCLUSION Patients with Tokyo Grade 2 acute cholecystitis had more complications and increased hospital charges when undergoing SA cholecystectomy.This data supports a selective approach to SA cholecystectomy for acute cholecystitis. | Christopher P Rice Krishnamurthy B Vaishnavi Celia Chao Daniel Jupiter August B Schaeffer Whitney R Jenson Lance W Griffin William J Mileski | 2019 | World Journal of Gastroenterology2019，25，48： | 8 |
