| 1 | National trends in resection of the distal pancreas显示文摘AIM:To investigate national trends in distal pancreatectomy(DP) through query of three national patient care databases.METHODS:From the Nationwide Inpatient Sample(NIS,2003-2009),the National Surgical Quality Improvement Project(NSQIP,2005-2010),and the Surveillance Epidemiology and End Results(SEER,2003-2009) databases using appropriate diagnostic and procedural codes we identified all patients with a diagnosis of a benign or malignant lesion of the body and/or tail of the pancreas that had undergone a partial or distal pancreatectomy.Utilization of laparoscopy was defined in NIS by the International Classification of Diseases,Ninth Revision correspondent procedure code;and in NSQIP by the exploratory laparoscopy or unlisted procedure current procedural terminology codes.In SEER,patients were identified by the International Classification of Diseases for Oncology,Third Edition diagnosis codes and the SEER Program Code Manual,third edition procedure codes.We analyzed the databases with respect to trends of inpatient outcome metrics,oncologic outcomes,and hospital volumes in patients with lesions of the neck and body of the pancreas that underwent operative resection.RESULTS:NIS,NSQIP and SEER identified 4242,2681 and 11 082 DP resections,respectively.Overall,laparoscopy was utilized in 15%(NIS) and 27%(NSQIP).No significant increase was seen over the course of the study.Resection was performed for malignancy in 59%(NIS) and 66%(NSQIP).Neither patient Body mass index nor comorbidities were associated with operative approach(P = 0.95 and P = 0.96,respectively).Mortality(3% vs 2%,P = 0.05) and reoperation(4% vs 4%,P = 1.0) was not different between laparoscopy and open groups.Overall complications(10% vs 15%,P < 0.001),hospital costs [44 741 dollars,interquartile range(IQR) 28 347-74 114 dollars vs 49 792 dollars,IQR 13 299-73 463,P = 0.02] and hospital length of stay(7 d,IQR 4-11 d vs 7 d,IQR 6-10,P < 0.001) were less when laparoscopy was utilized.One and two year survival after resection for malignancy were unchanged over the course of the study(ductal adenocarinoma 1-year 63.6% and 2-year 35.1%,P = 0.53;intraductal papillary mucinous neoplasm and nueroendocrine 1-year 90% and 2-year 84%,P = 0.25).The majority of resections were performed in teaching hospitals(77% NIS and 85% NSQIP),but minimally invasive surgery(MIS) was not more likely to be used in teaching hospitals(15% vs 14%,P = 0.26).Hospitals in the top decile for volume were more likely to be teaching hospitals than lower volume deciles(88% vs 43%,P < 0.001),but were no more likely to utilize MIS at resection.Complication rate in teaching and the top decile hospitals was not significantly decreased when compared to non-teaching(15% vs 14%,P = 0.72) and lower volume hospitals(14% vs 15%,P = 0.99).No difference was seen in the median number of lymph nodes and lymph node ratio in N1 disease when compared by year(P = 0.17 and P = 0.96,respectively).CONCLUSION:There appears to be an overall underutilization of laparoscopy for DP.Centralization does not appear to be occurring.Survival and lymph node harvest have not changed. | Armando Rosales-Velderrain Steven P Bowers Ross F Goldberg Tatyan M Clarke Mauricia A Buchanan John A Stauffer Horacio J Asbun | 2012 | World Journal of Gastroenterology2012，18，32： | 8 |

| 3 | 壳牌对未来车用能源多元化发展趋势的思考显示文摘面对能源短缺和环境污染的双重挑战,交通领域的转型升级不可避免。本文结合未来车用动力系统的发展趋势,对交通运输领域中应用的多种先进动力系统、清洁能源及替代燃料进行综述和评价,包括目前主要使用的传统液态化石燃料即汽、柴油及先进内燃机技术,清洁替代燃料(如生物燃料、天然气合成油(GTL)燃料、电转液(PTL)燃料、液化天然气(LNG)等),以及电气化动力系统(包括混合动力、纯电动和燃料电池)等,并着重讨论液体燃料。壳牌认为没有一种单一的解决方案可以解决复杂的能源问题,未来交通能源结构将呈现多种能源并存的特点,并分别适用于不同的场景。该文还介绍了壳牌近期基于不同政治、经济和社会发展程度提出的3种远景(壳牌“高山”、“海洋”和“天空”远景),提出壳牌对未来车用能源领域转型脱碳发展情景的思考。 | 贾恬 郑彬 Warnecke W Kolbeck A Aradi A Kofod M Clark R Wilbrand K | 2020 | 汽车安全与节能学报2020，11，1： | 2 |
