7Severe acute pancreatitis: pathogenesis, diagnosis and surgical management显示文摘BACKGROUND: Severe acute pancreatitis is a subtype of acute pancreatitis, associated with multiple organ failure and systemic inflammatory response syndrome. In this qualitative review we looked at the principles of pathogenesis, classification and surgical management of severe acute pancreatitis. We also looked at the current shift in paradigm in the management of severe acute pancreatitis since the guideline developed by the British Society of Gastroenterology.DATA SOURCES: Studies published between 1st January 1991 and 31st December 2015 were identified with Pub Med, MEDLINE, EMBASE and Google Scholar online search engines using the following Medical Subject Headings: 'acute pancreatitis, necrosis, mortality, pathogenesis, incidence' and the terms 'open necrosectomy and minimally invasive necrosectomy'.The National Institute of Clinical Excellence(NICE) Guidelines were also included in our study. Inclusion criteria for our clinical review included established guidelines, randomized controlled trials and non-randomized controlled trials with a follow-up duration of more than 6 weeks.RESULTS: The incidence of severe acute pancreatitis within the UK is significantly rising and pathogenetic theories are still controversial. In developed countries, the most common cause is biliary calculi. The British Society of Gastroenterology,acknowledges the Revised Atlanta criteria for prediction of severity. A newer Determinant-based system has been developed.The principle of surgical management of acute necrotizing pancreatitis requires intensive care management, identifying infection and if indicated, debridement of any infected necrotic area. The current procedures opted for include standard surgical open necrosectomy, endoscopic necrosectomy and minimally invasive necrosectomy. The current paradigm is shifting towards a step-up approach.CONCLUSIONS: Severe acute pancreatitis is still a subject of grey areas in its surgical management even though new studies have been recorded since the origin of the latest UK guidelines for management of severe acute pancreatitis.Mark Portelli Christopher David Jones 2017Hepatobiliary & Pancreatic Diseases International2017,16,2:201
8A general-purpose machine learning framework for predicting properties of inorganic materials显示文摘A very active area of materials research is to devise methods that use machine learning to automatically extract predictive models from existing materials data.While prior examples have demonstrated successful models for some applications,many more applications exist where machine learning can make a strong impact.To enable faster development of machine-learning-based models for such applications,we have created a framework capable of being applied to a broad range of materials data.Our method works by using a chemically diverse list of attributes,which we demonstrate are suitable for describing a wide variety of properties,and a novel method for partitioning the data set into groups of similar materials to boost the predictive accuracy.In this manuscript,we demonstrate how this new method can be used to predict diverse properties of crystalline and amorphous materials,such as band gap energy and glass-forming ability.Logan Ward Ankit Agrawal Alok Choudhary Christopher Wolverton 2016npj Computational Materials2016,,1:83

10从AO传统加压接骨板到新型内固定器原则显示文摘骨折内固定中生物学的重要性和保护骨和软组织,作为AO的第4项原则已受重视。AO传统加压接骨板对骨面的压迫会干扰骨皮质的血运,引起接骨板下方骨的结构性改变。有限接触动力加压接骨板(LC-DCP)可减小接骨板和骨的接触面积。锁定螺丝钉(LHS)、点接触固定器(PCFix)及微创固定系统(LISS)设计则因接骨板与骨面无接触和压迫,是新的一次变革。这种内固定器原理的概念可以用外固定支架来理解,可以防止任何对骨血运的破坏,其稳定性依赖于螺丝钉-接骨板组合的成角稳定性。带有锁定螺丝钉的新型微创固定系统(LISS)和锁定加压接骨板(LCP)可以为现代骨折手术治疗提供新的选择方法,是微创经皮接骨板技术(MIPO)的理想材料,并可以在疏松骨质内得到相当好的固定强度。然而,必须指出这些新型接骨板和螺丝钉并不能解决所有的问题,特别是在处理干骺端和骨干部骨折时,它们每一步的操作都需要有非常仔细的计划,包括重温AO经典的原则。Thomas P.Rüedi(托马斯.鲁迪) Christoph Sommer(克利斯托夫.邵墨) 罗炯 顾立强 2003中华创伤骨科杂志2003,5,3:169

12Clinical characteristics and outcome of a cohort of 101 patients with hepatocellular carcinoma显示文摘AIM To conduct a cohort study of 101 patients with hepatocellular carcinoma (HCC) presenting to a tertiary care medical referral center in Germany between 1997 and 1999.METHODS AND RESULTS Data were retrospectively analyzed by chart review. In 95cases (72 males and 23 females) sufficient data were available for analysis. Twenty-five (29%)of 8.5 patients were HBsAg or anti-HBc positive,21/85 (25%) were anti-HCV positive, and 6/85(7%) were positive for both HBV and HCV-markers. Age was significantly lower in HBV-positive patients than in the other two groups.Thirty-one (34%) of 90 patients had histories of alcohol abuse, In 79/ 94 (84%) patients,cirrhosis was diagnosed. Of these cirrhotic patients, 29/79 (37%) belonged to Child-Pugh's group (CHILD) A, 32/79 (40%) to CHILD B, and 18/79 (23%) to CHILD C. AFP was elevated in 61/91 (67%) patients. A single tumor nodule was found in 38/94 (40%), more than one nodule in 31/94 (34%), and 25/94 (26%) had a diffusely infiltrating tumor, i.e. the tumor margins could not be seen on imaging procedures. Portal vein thrombosis was present in 19/ 94 (20%).Imaging data consistent with lymph node metastases were found in 10/92 (11%), while distant metastases were found in 8/93 (9%).According to Okuda 28/94 (30%) were grouped to stage Ⅰ, 53/94 (56%) were grouped to stage Ⅱ, and 13/94 (14%) were grouped to stage Ⅲ.Survival data were available for 83 patients. The Kaplan-Meier estimate for median survival was 8.4 months. Factors influencing survival were the Okuda score, the presence of portal vein thrombosis, and the presence of ascites. The presence of non-complicated liver cirrhosis by itself, distant metastases, or infection with hepatitis viruses did not influence survival. AFP positivity by itself did not influence survival,though patients with an AFP value greater than 100μg/L did experience shortened survival.Treatment besides tamoxifen or supportive care was associated with prolonged survival. The influence of therapy on survival was most pronounced in Okuda stage Ⅱ patients. There was longer survival in those Okuda stage Ⅱpatients who were treated with percutaneous ethanol injection.CONCLUSION Even in a Iow incidence area such as Germany, the majority of HCC is caused by viral hepatitis and therefore potentially preventable. Reflecting the high proportion of advanced stage tumors in our patients, the median survival was poor. Patients who received active therapy had a longer survival.Christian Rabe Tillmann Pilz Christoph Klostermann Marc Berna Hans H.Schild Tilman Sauerbruch Wolfgang H.Caselmann 2001World Journal of Gastroenterology2001,7,2:60

16保持围手术期体温正常 一种减少手术并发症的简单、安全和有效的方法显示文摘围手术期低体温的危害尚未引起人们的重视,这种危害包括伤口感染率、心血管并发症和失血量的增加,以及病人的恢复和住院时间延长。而保持病人的体温在36℃或以上是有益的并可节省费用。 Frank等人对接受胸部。Christopher Mark Harper Thomas McNicholas S Gowrie-Mohan 黄宇光 2003英国医学杂志中文版2003,6,4:51
17Risk of cardiovascular,cardiac and arrhythmic complications in patients with non-alcoholic fatty liver disease显示文摘Non-alcoholic fatty liver disease(NAFLD)has emerged as a public health problem of epidemic proportions worldwide.Accumulating clinical and epidemiological evidence indicates that NAFLD is not only associated with liver-related morbidity and mortality but also with an increased risk of coronary heart disease(CHD),abnormalities of cardiac function and structure(e.g.,left ventricular dysfunction and hypertrophy,and heart failure),valvular heart disease(e.g.,aortic valve sclerosis)and arrhythmias(e.g.,atrial fibrillation).Experimental evidence suggests that NAFLD itself,especially in its more severe forms,exacerbates systemic/hepatic insulin resistance,causes atherogenic dyslipidemia,and releases a variety of pro-inflammatory,pro-coagulant and pro-fibrogenic mediators that may play important roles in the pathophysiology of cardiac and arrhythmic complications.Collectively,these findings suggest that patients with NAFLD may benefit from more intensive surveillance and early treatment interventions to decrease the risk for CHD and other cardiac/arrhythmic complications.The purpose of this clinical review is to summarize the rapidly expanding body of evidence that supports a strong association between NAFLD and cardiovascular,cardiac and arrhythmic complications,to briefly examine the putative biological mechanisms underlying this association,and to discuss some of the current treatment options that may influence both NAFLD and its related cardiac and arrhythmic complications.Stefano Ballestri Amedeo Lonardo Stefano Bonapace Christopher D Byrne Paola Loria Giovanni Targher 2014World Journal of Gastroenterology2014,20,7:55
18基于小波多尺度分析的奇性指数:一种新地震属性显示文摘传统的地震解释主要是观测地震振幅及相位的变化,但是地震振幅也会掩盖地下介质中真实的地质情况.在许多情况下,重要的地质信息可能是通过与振幅特征无关的奇异性参数来传递的.本文提出奇异性指数,即Hlder指数α(又被称为Lipschitz指数),可以作为一种新的地震属性,它能够准确反映数据中的奇点的位置和奇异性强度.Hlder指数α是对某一点上或某一点周围很小的范围内的奇异性强度的度量,大的α值表示低的奇异性(或高的正则性).研究表明α可以作为一种自然的能够精确刻画地层边界的地震属性.本文根据这一思想,对合成和实测的地震数据进行了小波基础上的多尺度分析研究,结果表明由本文的算法得到的α提高了对地层边界划分的能力,而这些地层界面在传统的地震振幅显示则不明显.李春峰 Christopher Liner 2005地球物理学报2005,48,4:46
19Contrast-enhanced endoscopic ultrasound in discrimination between focal pancreatitis and pancreatic cancer显示文摘瞄准:作为基于微容器的灌注特征把发炎区分开来与胰腺的癌的一个方法评估提高对比的 endosonography。方法:在有怀疑的慢性胰炎的 86 个病人(变老:62+/-12 年;性别:f/m 38/48 ) ,胰腺的损害被常规内视镜的 B 模式,力量 Doppler 超声和提高对比的力量模式检验(日立 EUB 525, SonoVue, 2.4 mL, Bracco ) 用为恶意的损害的下列标准:用常规力量 Doppler 的没有可检测的 vascularisation 在用 SonoVue 提高对比的技术和没有可检测的静脉的容器里面的短距离上的动脉的容器的扫描、不规则的外观损害。如果所有标准是可检测的,恶意的损害被假定[内视镜的超声(EUS ) 指导了的标准答案好针渴望细胞学,操作] 。没有瘤形成的慢性胰炎的标准在 SonoVue 的注射前被定义为没有可检测的 vascularisation,在在 SonoVue 的注射和动脉、静脉的容器的察觉以后的至少 20 公里的距离上的容器的常规外观。结果:常规 EUS 的敏感和特性为胰腺的癌症分别地是 73.2% 和 83.3% 。与恶意的胰腺的损害和特性在 56 个病人中的 51 个增加到 91.1% 的提高对比的 EUS 的敏感与长期的煽动性的胰腺的疾病在 30 个病人中的 28 个增加了到 93.3% 。结论:提高对比的内视镜的超声改进在慢性胰炎和胰腺的癌之间的区别。Michael Hocke Ewald Schulze Peter Gottschalk Theodor Topalidis Christoph F Dietrich 2006World Journal of Gastroenterology2006,12,2:43
20Endoscopic ultrasound elastography for evaluation of lymph nodes and pancreatic masses:A multicenter study显示文摘AIM:To evaluate the ability of endoscopic ultrasound(EUS) elastography to distinguish benign from malignant pancreatic masses and lymph nodes.METHODS:A multicenter study was conducted and included 222 patients who underwent EUS examination with assessment of a pancreatic mass(n=121) or lymph node(n=101).The classification as benign or malignant,based on the real time elastography pattern,was compared with the classif ication based on the B-mode EUS images and with the fi nal diagnosis obtained by EUS-guided fi ne needle aspiration(EUS-FNA) and/or by surgical pathology.An interobserver study was performed.RESULTS:The sensitivity and specificity of EUS elastography to differentiate benign from malignant pancreatic lesions are 92.3% and 80.0%,respectively,compared to 92.3% and 68.9%,respectively,for the conventional B-mode images.The sensitivity and specificity of EUS elastography to differentiate benign from malignant lymph nodes was 91.8% and 82.5%,respectively,compared to 78.6% and 50.0%,respectively,for the B-mode images.The kappa coefficient was 0.785 for the pancreatic masses and 0.657 for the lymph nodes.CONCLUSION:EUS elastography is superior compared to conventional B-mode imaging and appears to be able to distinguish benign from malignant pancreatic masses and lymph nodes with a high sensitivity,specificity and accuracy.It might be reserved as a second line examination to help characterise pancreatic masses after negative EUS-FNA and might increase the yield of EUS-FNA for lymph nodes.Marc Giovannini Botelberge Thomas Bories Erwan Pesenti Christian Caillol Fabrice Esterni Benjamin Monges Geneviève Arcidiacono Paolo Deprez Pierre Yeung Robert Schimdt Walter Schrader Hanz Szymanski Carl Dietrich Christoph Eisendrath Pierre Van Laethem Jean-Luc Devière Jacques Vilmann Peter Saftoiu Andrian 2009World Journal of Gastroenterology2009,15,13:48
