4Nitrosamine and related food intake and gastric and oesophageal cancer risk: A systematic review of the epidemiological evidence显示文摘瞄准:学习在亚硝酸根和亚硝基胺吸入和胃的癌症(GC ) 之间的协会在肉和处理的肉吸入之间, GC 和食道的癌症(OC ) ,并且在保存的鱼,蔬菜和吸的食物摄取和 GC 之间。方法:在这篇文章,我们从 1985-2005 考察了所有出版的队和盒子控制研究,并且分析了在亚硝基胺和亚硝酸根吸入和最重要的相关食物摄取(喝的肉和处理的肉,保存蔬菜和鱼,吸的食物和啤酒) 和 GC 或 OC 风险之间的关系。61 研究, 11 个队和 50 盒子控制研究被包括。结果:从盒子控制研究的证据与 GC 支持了在亚硝酸根和亚硝基胺吸入之间的一个协会,但是证据在与 OC 的关系是不够的。盒子控制研究的一个高比例为两个瘤(GC 上的 16 研究中的 11 个和 OC 上的 18 研究中的 11 个) 与肉吸入发现了一个积极协会。盒子控制研究的一个相对大的数字显示出支持在处理的肉吸入和 GC 和 OC 风险之间的一个积极协会的相当一致的结果(GC 上的 14 研究中的 10 个和 9 中的 8 个在 OC 上学习) 。几乎所有盒子控制研究发现了在保存的鱼,蔬菜和吸的食物摄取和 GC 之间的一个积极、重要的协会。关于 OC 的证据是更有限的。从队的证据学习的外套从盒子控制研究比那不够或更不一致。结论:可得到的证据支持在亚硝酸根和亚硝基胺吸入和 GC 之间的一个积极协会,在肉和处理的肉吸入和 GC 和 OC 之间,并且在保存的鱼,蔬菜和吸的食物摄取和 GC 之间,但是不是最后的。Paula Jakszyn Carlos Alberto González 2006World Journal of Gastroenterology2006,12,27:42
5Blood loss,predictors of bleeding,transfusion practice and strategies of blood cell salvaging during liver transplantation显示文摘Blood loss during liver transplantation (OLTx) is a common consequence of pre-existing abnormalities of the hemostatic system,portal hypertension with multiple collateral vessels,portal vein thrombosis,previous abdominal surgery,splenomegaly,and poor 'functional' recovery of the new liver.The intrinsic coagulopathic features of end stage cirrhosis along with surgical technical difficulties make transfusion-free liver transplantation a major challenge,and,despite the improvements in understanding of intraoperative coagulation profiles and strategies to control blood loss,the requirements for blood or blood products remains high.The impact of blood transfusion has been shown to be significant and independent of other well-known predictors of posttransplant-outcome.Negative effects on immunomodulation and an increased risk of postoperative complications and mortality have been repeatedly demonstrated.Isovolemic hemodilution,the extensive utilization of thromboelastogram and the use of autotransfusion devices are among the commonly adopted procedures to limit the amount of blood transfusion.The use of intraoperative blood salvage and autologous blood transfusion should still be considered an important method to reduce the need for allogenic blood and the associated complications.In this article we report on the common preoperative and intraoperative factors contributing to blood loss,intraoperative transfusion practices,anesthesiologic and surgical strategies to prevent blood loss,and on intraoperative blood salvaging techniques and autologous blood transfusion.Even though the advances in surgical technique and anesthetic management,as well as a better understanding of the risk factors,have resulted in a steady decrease in intraoperative bleeding,most patients still bleed extensively.Blood transfusion therapy is still a critical feature during OLTx and various studies have shown a large variability in the use of blood products among different centers and even among individual anesthesiologists within the same center.Unfortunately,despite the large number of OLTx performed each year,there is still paucity of large randomized,multicentre,and controlled studies which indicate how to prevent bleeding,the transfusion needs and thresholds,and the 'evidence based' perioperative strategies to reduce the amount of transfusion.Feltracco Paolo Brezzi Marialuisa Barbieri Stefania Galligioni Helmut Milevoj Moira Carollo Cristiana Ori Carlo 2013World Journal of Hepatology2013,5,1:37

10Diabetic foot syndrome:Immune-inflammatory features as possible cardiovascular markers in diabetes显示文摘Diabetic foot ulcerations have been extensively reported as vascular complications of diabetes mellitus associated with a high degree of morbidity and mortality. Diabetic foot syndrome(DFS), as defined by the World Health Organization, is an 'ulceration of the foot(distally from the ankle and including the ankle) associated with neuropathy and different grades of ischemia and infection'. Pathogenic events able to cause diabetic foot ulcers are multifactorial.Among the commonest causes of this pathogenic pathway it's possible to consider peripheral neuropathy, foot deformity, abnormal foot pressures, abnormal joint mobility, trauma, peripheral artery disease. Several studies reported how diabetic patients show a higher mortality rate compared to patients without diabetes and in particular these studies under filled how cardiovascular mortality and morbidity is 2-4 times higher among patients affected by type 2 diabetes mellitus. This higher degree of cardiovascular morbidity has been explained as due to the observed higher prevalence of major cardiovascular risk factor, of asymptomatic findings of cardiovascular diseases, and of prevalence and incidence of cardiovascular and cerebrovascular events in diabetic patients with foot complications. In diabetes a fundamental pathogenic pathway of most of vascular complications has been reported as linked to a complex interplay of inflammatory, metabolic and procoagulant variables. These pathogenetic aspects have a direct interplay with an insulin resistance, subsequent obesity, diabetes, hypertension, prothrombotic state and blood lipid disorder. Involvement of inflammatory markers such as IL-6 plasma levels and resistin in diabetic subjects as reported by Tuttolomondo et al confirmed the pathogenetic issue of the a 'adipo-vascular' axis that may contribute to cardiovascular risk in patients with type 2 diabetes. This 'adipo-vascular axis' in patients with type 2 diabetes has been reported as characterized by lower plasma levels of adiponectin and higher plasma levels of interleukin-6 thus linking foot ulcers pathogenesis to microvascular and inflammatory events. The purpose of this review is to highlight the immune inflammatory features of DFS and its possible role as a marker of cardiovascular risk in diabetes patients and to focus the management of major complications related to diabetes such as infections and peripheral arteriopathy.Antonino Tuttolomondo Carlo Maida Antonio Pinto 2015World Journal of Orthopedics2015,6,1:37
11Early respiratory complications after liver transplantation显示文摘The poor clinical conditions associated with end-stage cirrhosis,pre-existing pulmonary abnormalities,and high comorbidity rates in patients with high Model for End-Stage Liver Disease scores are all well-recognized factors that increase the risk of pulmonary complications after orthotopic liver transplantation(OLT)surgery.Many intraoperative and postoperative events,such as fluid overload,massive transfusion of blood products,hemodynamic instability,unexpected coagulation abnormalities,renal dysfunction,and serious adverse effects of reperfusion syndrome,are other factors that predispose an individual to postoperative respiratory disorders.Despite advances in surgical techniques and anesthesiological management,the lung may still suffer throughout the perioperative period from various types of injury and ventilatory impairment,with different clinical outcomes.Pulmonary complications after OLT can be classified as infectious or non-infectious.Pleural effusion,atelectasis,pulmonary edema,respiratory distress syndrome,and pneumonia may contribute considerably to early morbidity and mortality in liver transplant patients.It is of paramount importance to accurately identify lung disorders because infectious pulmonary complications warrant speedy and aggressive treatment to prevent diffuse lung injury and the risk of evolution into multisystem organ failure.This review discusses the most common perioperative factors that predispose an individual to postoperative pulmonary complications and these complications’early clinical manifestations after OLT and influence on patient outcome.Paolo Feltracco Cristiana Carollo Stefania Barbieri Tommaso Pettenuzzo Carlo Ori 2013World Journal of Gastroenterology2013,19,48:32

13Immune regulatory properties of multipotent mesenchymal stromal cells:Where do we stand?显示文摘Multipotent mesenchymal stromal cells (MSC) can be isolated and efficiently expanded from almost every single body tissue and have the ability of self-renewal and differentiation into various mesodermal cell lineages. Moreover, these cells are considered immunologically privileged, related to a lack of surface expression of costimulatory molecules required for complete T cell activation. Recently, it has been observed that MSC are capable of suppressing the immune response by inhibiting the maturation of dendritic cells and suppressing the function of T lymphocytes, B lymphocytes and natural killer cells in autoimmune and inflammatory diseases as a new strategy for immunosuppression. The understanding of immune regulation mechanisms by MSC is necessary for their use as immunotherapy in clinical applications for several diseases.ênio José Bassi Carlos Alberto Mayora Aita Niels Olsen Saraiva Camara 2011World Journal of Stem Cells2011,3,1:27
14Laparoscopic and robot-assisted laparoscopic digestivesurgery:Present and future directions显示文摘Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen's fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated.Juan C Rodríguez-Sanjuán Marcos Gómez-Ruiz Soledad Trugeda-Carrera Carlos Manuel-Palazuelos Antonio López-Useros Manuel Gómez-Fleitas 2016World Journal of Gastroenterology2016,22,6:27
15Liver enzymes,metabolomics and genome-wide association studies:From systems biology to the personalized medicine显示文摘For several decades,serum levels of alanine(ALT) and aspartate(AST) aminotransferases have been regarded as markers of liver injury,including a wide range of etiologies from viral hepatitis to fatty liver.The increasing worldwide prevalence of metabolic syndrome and cardiovascular disease revealed that transaminases are strong predictors of type 2 diabetes,coronary heart disease,atherothrombotic risk profile,and overall risk of metabolic disease.Therefore,it is plausible to suggest that aminotransferases are surrogate biomarkers of 'liver metabolic functioning' beyond the classical concept of liver cellular damage,as their enzymatic activity might actually reflect key aspects of the physiology and pathophysiology of the liver function.In this study,we summarize the background information and recent findings on the biological role of ALT and AST,and review the knowledge gained from the application of genome-wide approaches and 'omics' technologies that uncovered new concepts on the role of aminotransferases in human diseases and systemic regulation of metabolic functions.Prediction of biomolecular interactions between the candidate genes recently discovered to be associated with plasma concentrations of liver enzymes showed interesting interconnectivity nodes,which suggest that regulation of aminotransferase activity is a complex and highly regulated trait.Finally,links between aminotransferase genes and metabolites are explored to understand the genetic contributions to the metabolic diversity.Silvia Sookoian Carlos J Pirola 2015World Journal of Gastroenterology2015,21,3:27
16Endoscopic management of biliary complications after liver transplantation: An evidence-based review显示文摘Biliary tract diseases are the most common complications following liver transplantation(LT) and usually include biliary leaks, strictures, and stone disease. Compared to deceased donor liver transplantation in adults, living donor liver transplantation is plagued by a higher rate of biliary complications. These may be promoted by multiple risk factors related to recipient, graft, operative factors and post-operative course. Magnetic resonance cholangiopancreatography is the first-choice examination when a biliary complication is suspected following LT, in order to diagnose and to plan the optimal therapy; its limitations include a low sensitivity for the detection of biliary sludge. For treating anastomotic strictures, balloon dilatation complemented with the temporary placement of multiple simultaneous plastic stents has become the standard of care and results in stricture resolution with no relapse in > 90% of cases. Temporary placement of fully covered self-expanding metal stents(FCSEMSs) has not been demonstrated to be superior(except in a pilot randomized controlled trial that used a special design of FCSEMSs), mostly because of the high migration rate of current FCSEMSs models. The endoscopic approach of non-anastomotic strictures is technically more difficult than that of anastomotic strictures due to the intrahepatic and/or hilar location of strictures, and the results are less satisfactory. For treating biliary leaks, biliary sphincterotomy and transpapillary stenting is the standard approach and results in leak resolution in more than 85% of patients. Deep enteroscopy is a rapidly evolving technique that has allowed successful treatment of patients who were not previously amenable to endoscopic therapy. As a result, the percutaneous and surgical approaches are currently required in a minority of patients.Carlos Macías-Gómez Jean-Marc Dumonceau 2015World Journal of Gastrointestinal Endoscopy2015,7,6:25
17异重流成因和异重岩沉积特征显示文摘河流在洪水期携带大量陆源碎屑,当其入湖或入海后,由于洪水密度大于周围水体的密度,洪水发生下沉并沿盆地底部长距离运移,形成陆源下潜流或异重流。异重流形成的相关沉积岩被统称为异重岩。异重岩通常由一个底部的反粒序单元和一个顶部的正粒序单元组成,反粒序单元反映了异重流能量的逐渐增强,正粒序反映了流体能量的逐渐减弱。异重流以3种方式搬运碎屑颗粒,即底载搬运、悬浮搬运和漂浮搬运。根据搬运方式的不同,异重岩分为3类岩相,即底载成因的B类岩相、悬载成因的S类岩相和漂浮物成因的L类岩相。异重流的沉积充填形成了河道、堤岸和朵叶体3类微相,内部岩相变化极为发育。异重岩的沉积特征虽然典型且较易识别,但是常被误认为是砂质碎屑流、滨岸相、三角洲相或河流相沉积。Carlos Zavala 潘树新 2018岩性油气藏2018,30,1:26
18MicroRNAs as possible biomarkers for diagnosis and prognosis of hepatitis b- and c-related-hepatocellularcarcinoma显示文摘Aim of the present review is to summarize the current knowledge about the potential relationship between mi RNAs and hepatitis B virus(HBV)-hepatitis C virus(HCV) related liver diseases. A systematic computerbased search of published articles, according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis Statement, was performed to identify relevant studies on usefulness of serum/plasma/urine mi RNAs, as noninvasive biomarkers for early detection of HBV and HCV-induced hepatocellular carcinoma(HCC) development, as well as for its prognostic evaluation. The used Medical Subject Headings terms and keywords were: 'HBV', 'HCV', 'hepatocellular carcinoma', 'micro RNAs', 'mi RNAs', 'diagnosis', 'prognosis', 'therapy', 'treatment'. Some serum/plasma mi RNAs, including mi R-21, mi R-122, mi-125a/b, mi R-199a/b, mi R-221, mi R-222, mi R-223, mi R-224 might serve as biomarkers for early diagnosis/prognosis of HCC, but, to date, not definitive results or well-defined panels of mi RNAs have been obtained. More well-designed studies, focusing on populations of different geographical areas and involving larger series of patients, should be carried out to improve our knowledge on the potential role of mi RNAs for HCC early detection and prognosis.Sirio Fiorino Maria Letizia Bacchi-Reggiani Michela Visani Giorgia Acquaviva Adele Fornelli Michele Masetti Andrea Tura Fabio Grizzi Matteo Zanello Laura Mastrangelo Raffaele Lombardi Luca Di Tommaso Arrigo Bondi Sergio Sabbatani Andrea Domanico Carlo Fabbri Paolo Leandri Annalisa Pession Elio Jovine Dario de Biase 2016World Journal of Gastroenterology2016,22,15:25
19Different profile of cytokine synthesis according to the severity of acute pancreatitis显示文摘AIM: To evaluate the cellular synthetic ability of cytokines involved in pro- and anti-inflammatory reactions in patients with AP.METHODS: Sixty-seven patients with AP (16 severe,51 mild) and 10 controls were included in the study.Cultures of whole blood were performed in samples obtained within the first 72 h from the onset of pain.Serum levels of interleukins (IL) 6, 8, 10, and TNF-α were measured at baseline and in the supernatant of cultures with (functional reserve) or without stimulation with phytohemaglutinin.RESULTS: Basal levels of cytokines were significantly higher in patients with severe AP. A significant increase of all pro-inflammatory cytokines vs basal levels was observed in the supernatant after 24 h of whole blood cultures in patients, but not in controls. In contrast, IL-10 increased significantly in the supernatant of cultures only in patients with mild AP. Cells showed a statistically significant functional reserve for all IL in patients with mild, but only for pro-inflammatory cytokines in patients with severe AP.CONCLUSION: A marked activation of immune system may be observed in patients with AP, being balanced between pro- and anti-inflammatory cytokines in patients with mild but not severe AP. A reduced functional reserve for the synthesis of IL-10 may be observed in patients with severe AP, which might lead to a worst prognosis.Raquel Laveda Juan Martínez Carlos Mu■oz Juan Carlos Penalva Jesus Sáez Germán Belda Salvador Navarro Faust Feu Anton Mas José Ma Palazón José Sánchez-Payá José Such Miguel Pérez-Mateo 2005World Journal of Gastroenterology2005,11,34:24
20利用声发射法和变形率变化法联合测定地应力显示文摘针对葡萄牙南部Neves-Corvo,SA(Somincor)矿区一垂直钻孔钻取的岩芯,利用声发射法(AE法)和变形率变化法(DRA法)联合测定该区域垂直向地应力。试验表明:矿区垂直向地应力呈现随深度增加而增加的趋势,但由于受褶皱、断裂等多种地质因素的影响,随深度的增加,由AE法和DRA法测得的地应力值差别也越大;通过AE和DRA试验曲线确定地应力在较大程度上依赖于对试验曲线中拐点的判断,而这种判断必须结合曲线本身的特点进行。在同一个试样上同时利用AE法和DRA法测定其地应力不仅是可行的,二者还可相互印证,确保了试验数据的可靠性。谢强 邱鹏 余贤斌 Carlos Dinis da Gama 2010煤炭学报2010,35,4:24
