| 1 | A matched-pair analysis of laparoscopic versus open pancreaticoduodenectomy: oncological outcomes using Leeds Pathology Protocol显示文摘BACKGROUND: Laparoscopic pancreaticoduodenectomy(LPD)is a safe procedure. Oncological safety of LPD is still a matter for debate. This study aimed to compare the oncological outcomes,in terms of adequacy of resection and recurrence rate following LPD and open pancreaticoduodenectomy(OPD).METHODS: Between November 2005 and April 2009, 12LPDs(9 ampullary and 3 distal common bile duct tumors)were performed. A cohort of 12 OPDs were matched for age,gender, body mass index(BMI) and American Society of Anesthesiologists(ASA) score and tumor site.RESULTS: Mean tumor size LPD vs OPD(19.8 vs 19.2 mm,P=0.870). R0 resection was achieved in 9 LPD vs 8 OPD(P=1.000). The mean number of metastatic lymph nodes and total number resected for LPD vs OPD were 1.1 vs 2.1(P=0.140)and 20.7 vs 18.5(P=0.534) respectively. Clavien complications grade I/II(5 vs 8), III/IV(2 vs 6) and pancreatic leak(2 vs 1)were statistically not significant(LPD vs OPD). The mean high dependency unit(HDU) stay was longer in OPD(3.7 vs 1.4 days,P<0.001). There were 2 recurrences each in LPD and OPD(logrank,P=0.983). Overall mortality for LPD vs OPD was 3 vs 6(log-rank, P=0.283) and recurrence-related mortality was 2 vs 1.There was one death within 30 days in the OPD group secondary to severe sepsis and none in the LPD group.CONCLUSIONS: Compared to open procedure, LPD achieved a similar rate of R0 resection, lymph node harvest and longterm recurrence for tumors less than 2 cm. Though technically challenging, LPD is safe and does not compromise oncological outcome. | Abdul R Hakeem Caroline S Verbeke Alison Cairns Amer Aldouri Andrew M Smith Krishna V Menon | 2014 | Hepatobiliary & Pancreatic Diseases International2014，13，4： | 24 |
| 2 | 汽车采用的无级变速功率分流变速器的设计显示文摘在汽车应用方面提出了无级变速功率分流变速箱的一种设想 ,该装置由两可变速带轮 (变速器 )和一行星齿轮系所谓太阳轮和内齿圈三转动构件组合而成。“功率分流”的布置特点是输入轴同时把功率传到太阳轮和主动带轮 ,并通过变速器传到行星齿轮传动的内齿圈。因为输入轴传递的输入功率一分为二 (传到太阳轮和主动带轮 ) ,变速器中仅通过输入轴总功率流的一小部分 ,行星齿轮传动的第三转动件 (转臂 )收集了由内齿圈和太阳轮传来的功率流 ,把总功率传到输出轴传到车辆。该特徵提高了发动机功率在汽车应用的许可范围 ,该特徵特别在低速 -高转矩情况下提供无级变速可变传动比的范围时还降低了与动力传动有关的功率损失。建立一个所谓“增益系数”,用它通过变速箱的可变速元件和速比间隔来确定总功率流的两个分量的大小。用一外齿轮箱可以在发动机和变速箱的最佳范围内扩展无级变速范围。提出了一个采用外啮合有级齿轮传动 (同步变速器 )实现有效传动比间隔的无级变速范围应用于汽车的设计程序 。 | V H Mucino Z Lu J E Smith M Kimcikiewicz B Cowan | 2004 | 传动技术2004，18，1： | 7 |

| 4 | Endoscopic retrograde cholangiography for pediatric choledocholithiasis: Assessing the need for endoscopic intervention显示文摘AIM:To assess pediatric patients for choledocholithiasis.We applied current adult guidelines to identify predictivefactors in children.METHODS:A single-center retrospective analysis was performed at a tertiary children's hospital.We evaluated 44 consecutive pediatric patients who underwent endoscopic retrograde cholangiography(ERCP) for suspected choledocholithiasis.Patients were stratified into those with common bile duct stones(CBDS) at ERCP vs those that did not using the American Society of Gastrointestinal Endoscopy(ASGE) guidelines(Very Strong and Strong criteria) for suspected CBDS.RESULTS:CBDS were identified in 84% at the time of ERCP.Abdominal ultrasound identified CBDS in 36% of patients.Conjugated bilirubin ≥ 0.5 mg/d L was an independent risk factor for CBDS(P = 0.003).The Very Strong(59.5%) and Strong(48.6%) ASGE criteria identified the majority of patients(P = 0.0001).A modified score using conjugated bilirubin had a higher sensitivity(81.2% vs 59.5%) and more likely to identify a stone than the standard criteria,odds ratio of 25.7 compared to 8.8.Alanine aminotransferase and gamma-glutamyl transferase values identified significant differences in a subset of patients with odds ratio of 4.1 and 3.25,respectively.CONCLUSION:Current adult guidelines identified the majority of pediatric patients with CBDS,but specific pediatric guidelines may improve detection,thus decreasing risks and unnecessary procedures. | Douglas S Fishman Bruno P Chumpitazi Isaac Raijman Cynthia Man-Wai Tsai E O’Brian Smith Mark V Mazziotti Mark A Gilger | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，11： | 6 |
| 5 | 猪霉菌毒素中毒的新概念显示文摘霉菌毒素是真菌的次级代谢产物,可以降低畜禽生产性能和改变新陈代谢(wannemacher等,1991)。动物采食被霉菌毒素污染的饲料而引发的病理状态称为霉菌毒素中毒。猪霉菌毒素中毒会对养猪生产造成严重的不良影响。本文综述了各种霉菌毒素对猪生长性能、繁殖性能和免疫功能的影响,各种霉菌毒素间的协同作用以及猪霉菌毒素中毒的最新研究成果。 | Trevor K Smith Gabriel Diaz Swamy H V LN 苗朝华(摘译) | 2007 | 养猪2007，，5： | 6 |
