7Contribution of the IL-17/IL-23 axis to the pathogenesis of inflammatory bowel disease显示文摘Inflammatory bowel diseases(IBDs) are chronic disorders of modern society, requiring management strategies aimed at prolonging an active life and establishing the exact etiology and pathogenesis.These idiopathic diseases have environmental, genetic,immunologic, inflammatory, and oxidative stress components. On the one hand, recent advances have shown that abnormal immune reactions against the microorganisms of the intestinal flora are responsible for the inflammation in genetically susceptible individuals. On the other hand, in addition to T helper cell-type(Th) 1 and Th2 immune responses,other subsets of T cells, namely regulatory T cells and Th17 maintained by IL-23 are likely to develop IBD. IL-23 acts on innate immune system members and also facilitates the expansion and maintenance of Th17 cells. The IL-17/IL-23 axis is relevant in IBD pathogenesis both in human and experimental studies. Novel biomarkers of IBD could be calprotectin,microRNAs, and serum proinflammatory cytokines.An efficient strategy for IBD therapy is represented by the combination of IL-17 A and IL-17 F in acute IL-17 A knockout TNBS-induced colitis, and also definite decrease of the inflammatory process in IL-17 F knockout, DSS-induced colitis have been observed.Studying the correlation between innate and adaptive immune systems, we hope to obtain a focused reviewin order to facilitate future approaches aimed at elucidating the immunological mechanisms that control gut inflammation.Cristina-Sorina Cǎanǎ Ioana Berindan Neagoe Vasile Cozma Cristian Magdas Flaviu Tǎbǎan Dan Lucian Dumitrasu 2015World Journal of Gastroenterology2015,21,19:37
8AGNP精神科治疗药物监测共识指南:2011显示文摘治疗药物监测(Therapeutic drug monitoring,TDM),如通过定量测定血清或血浆药物浓度指导用药剂量优化,已经成为对患者进行精神药物治疗的很有价值的工具。在患者用药依从性难以判断、药物耐受性不佳、治疗剂量下无效以及可能存在药代动力学药物-药物相互作用等情况下,测定药物浓度是很有用的。在精神科,有可能明显获益于TDM的主要患者群体包括儿童、孕妇、老年患者、智力障碍患者、涉及司法的患者、已知或怀疑携带药代动力学相关基因变异的患者,以及合并躯体疾病影响药代动力学的患者。然而,只有将TDM充分整合到临床治疗过程中去,才能发挥其优化药物治疗的潜在优势。为了促进TDM的合理应用,神经精神药理学与药物精神病学协会(Arbeitsgemeinschaft für Neuropsychopharmakologie und Pharmakopsychiatrie,AGNP)的TDM专家组在2004年发表了精神药物治疗药物监测指南。之后,随着知识不断更新,又有许多可能需要进行TDM的新药上市。因此,本次更新将神经精神药物的种类扩展到了128种,并将其TDM必要性划分为从'强烈推荐'到'可能有用'的四个等级。经过大量细致且全面的文献检索与分门别类的汇总整理,将基于循证医学理念的'治疗参考浓度范围'和'剂量相关参考浓度范围'呈现给大家。本共识指南引入了'实验室警戒浓度'的新概念,即实验室需要马上告知治疗医生的药物浓度上限。本共识指南还给出了诸如药物作为细胞色素P450酶的底物和抑制剂的性质,代谢物与母药浓度比值的常见范围,以及与结果解释相关的内容,还提供了何时将TDM与遗传药理学检测相结合的建议。遵循本指南,有助于改善许多患者精神药物治疗的效果,特别是那些存在药代动力学异常的患者。TDM是一门交叉学科,有时针对看起来不一致的数据,需要多学科坦诚地讨论,只有这样,患者才能从这种合作中获益。Hiemke C Baumann P Bergemann N Conca A Dietmaier O Egberts K Fric M Gerlach M Greiner C Gründer G Haen E Havemann-Reinecke U Jaquenoud Sirot E Kirchherr H Laux G Lutz UC Messer T Müller MJ Pfuhlmann B Rambeck B Riederer P Schoppek B Stingl J Uhr M Ulrich S Waschgler R Zernig G 李文标(译) 果伟(译) 阮灿军(译) 贺静(译) 汤宜朗(审校) 王传跃(审校) 2016实用药物与临床2016,19,10:37

10血管内超声去肾交感神经术治疗高血压:一项多中心,国际,单盲,随机,假手术对照试验显示文摘早期研究表明,基于射频的去肾交感神经术可降低中度高血压患者的血压。研究者研究了在没有使用抗高血压药物的情况下,使用血管内超声去。肾交感神经术是否会降低高血压患者的动态血压。刘青 叶鹏 Azizi M Schmieder RE Mahfoud F Weber MA Daemen J Davies J Basile J Kirtane AJ Wang Y Lobo MD Saxena M Feyz L Rader F Lurz P Sayer J Sapoval M Levy T Sanghvi K Abraham J Sharp ASP Fisher NDL Bloch MJ Reeve-Stoffer H Coleman L Mullin C Mauri L 2018中华高血压杂志2018,26,10:27
11光复散射对消光法粒径测量的影响:复散射模型与数值模拟显示文摘复散射效应在光散射颗粒测量中不仅重要 ,且尚未得到很好解决。采用蒙特卡罗方法 ,对不同的光波长 ,颗粒浓度以及收接器条件下的光复散射进行了数值模拟 ,数值算法程序经与四通量模型进行对比验证 ,数值结果与单散射条件的郎伯比尔模型进行比较 ,进而讨论了复散射效应对消光法颗粒粒径测量影响。表明复散射对消光法颗粒测量的影响不仅取决于颗粒系自身的浓度 ,而且接收器的几何尺寸和接收位置起着非常重要的作用 ,减小颗粒介质层厚度和减小光接收器接收面积 ,增大接收距离以及减小接收角都能减小复散射效应对消光法粒径测量的影响。苏明旭 任宽芳 Grehan G 蔡小舒 Rozé C Girasole T 2004光学学报2004,24,5:25
12Angiographic evaluation and management of acute gastrointestinal hemorrhage显示文摘Although most cases of acute nonvariceal gastrointestinal hemorrhage either spontaneously resolve or respond to medical management or endoscopic treatment,there are still a significant number of patients who require emergency angiography and transcatheter treatment.Evaluation with noninvasive imaging such as nuclear scintigraphy or computed tomography may localize the bleeding source and/or confirm active hemorrhage prior to angiography.Any angiographic evaluation should begin with selective catheterization of the artery supplying the most likely site of bleeding,as determined by the available clinical,endoscopic and imaging data.If a hemorrhage source is identified,superselective catheterization followed by transcatheter microcoil embolization is usually the most effective means of successfully controlling hemorrhage while minimizing potential complications.This is now wellrecognized as a viable and safe alternative to emergency surgery.In selected situations transcatheter intra-arterial infusion of vasopressin may also be useful in controlling acute gastrointestinal bleeding.One must be aware of the various side effects and potential complications associated with this treatment,however,and recognize the high re-bleeding rate.In this article we review the current role of angiography,transcatheter arterial embolization and infusion therapy in the evaluation and management of nonvariceal gastrointestinal hemorrhage.T Gregory Walker Gloria M Salazar Arthur C Waltman 2012World Journal of Gastroenterology2012,18,11:24

16Contribution of oxidative stress to pulmonary arterial hypertension显示文摘Recent data implicate oxidative stress as a mediator of pulmonary hypertension (PH) and of the associated pathological changes to the pulmonary vasculature and right ventricle (RV). Increases in reactive oxygen species (ROS), altered redox state, and elevated oxidant stress have been demonstrated in the lungs and RV of several animal models of PH, including chronic hypoxia, monocrotaline toxicity, caveolin-1 knock-out mouse, and the transgenic Ren2 rat which overexpresses the mouse renin gene. Generation of ROS in these models is derived mostly from the activities of the nicotinamide adenine dinucleotide phosphate oxidases, xanthine oxidase, and uncoupled endothelial nitric oxide synthase. As disease progresses circulating monocytes and bone marrow-derived monocytic progenitor cells are attracted to and accumulate in the pulmonary vasculature. Once established, these inflammatory cells generate ROS and secrete mitogenic and fibrogenic cytokines that induce cell proliferation and fibrosis in the vascular wall resulting in progressive vascular remodeling. Deficiencies in antioxidant enzymes also contribute to pulmonary hypertensive states. Current therapies were developed to improve endothelial function, reduce pulmonary artery pressure, and slow the progression of vascular remodeling in the pulmonary vasculature by targeting deficiencies in either NO (PDE-type 5 inhibition) or PGI 2 (prostacyclin analogs), or excessive synthesis of ET-1 (ET receptor blockers) with the intent to improve patient clinical status and survival. New therapies may slow disease progression to some extent, but long term management has not been achieved and mortality is still high. Although little is known concerning the effects of current pulmonary arterial hypertension treatments on RV structure and function, interest in this area is increasing. Development of therapeutic strategies that simultaneously target pathology in the pulmonary vasculature and RV may be beneficial in reducing mortality associated with RV failure.Vincent G DeMarco Adam T Whaley-Connell James R Sowers Javad Habibi Kevin C Dellsperger 2010World Journal of Cardiology2010,2,10:21
17世界卫生组织(WHO)造血与淋巴组织肿瘤分类方案:临床顾问委员会会议报告显示文摘引言 :从 1995年开始 ,欧洲病理学工作者协会和血液病理学会一直致力于制定一个新的世界卫生组织 (WHO)血液恶性肿瘤分类方案 ,该分类方案包括淋巴系肿瘤、髓系肿瘤、组织细胞肿瘤和肥大细胞肿瘤。 材料与方法 :此项 WHO计划共组成十个病理学工作者委员会 ,负责确定病种和作出定义。另外还成立一个由国际血液学家和肿瘤学家组成的临床顾问委员会 (CAC)以保证该分类的临床实用性。 1997年 11月召开会议讨论了与该分类有关的临床问题。 结果 :WHO采纳了 1994年国际淋巴瘤研究组 (IL SG)报告的修订欧美淋巴系肿瘤分类 (REAL)方案作为淋巴系肿瘤的分类方案。该方案的分类方法遵循以下原则 :分类应是联合应用形态学、免疫表型、遗传特征及临床特征能够清楚界定的“真实存在”(“real”)病种的名录 ,上述各项特征的相对重要性因病种不同而异 ,不存在任何“金标准”。 WHO将 REAL分类原则延用于髓系肿瘤和组织细胞肿瘤 ,髓系肿瘤的分类包括联合应用细胞形态学和细胞遗传学异常能够界定的各个病种。围绕一系列临床问题召集的这次 CAC会议 ,就提交的大多数问题达成共识 ,这些问题及共识将详述于下。对于另外一些问题 ,CAC认为淋巴系肿瘤临床分组既无必要也不必需 ,患者的治疗取决于淋巴瘤的具体类型 ,如有?N L Harris E S Jaffe J Diebold G Flandrin H K Muller-Hermelink J Vardiman T A Lister C D Bloomfield 张凤奎 郝玉书 2001白血病.淋巴瘤2001,10,3:20
18Surgical management of polycystic liver disease显示文摘Adult polycystic liver disease (PCLD) is an autosomal dominant condition commonly associated with autosomal dominant polycystic kidney disease (ADPKD). However in the last decade, it has been recognized that there is a distinct form of autosomal dominant PCLD that arises without concomitant ADPKD. Early knowledge of the pathogenesis was gained from the study of hepatic cysts in patients with ADPKD. Bile duct overgrowth after embryogenesis results in cystic hepatic dilatations that are known as biliary microhamartomas or von Meyenburg complexes. Further dilatation arises from cellular proliferation and fluid secretion into these cysts. There is a variable, broad spectrum of manifestations of PCLD. Although PCLD is most often asymptomatic, massive hepatomegaly can lead to disabling symptoms of abdominal pain, early satiety, persistent nausea, dyspnea, ascites, biliary obstruction, and lower body edema. Complications of PCLD include cyst rupture and cyst infection. Also, there are associated medical problems, especially intracranial aneurysms and valvular heart disease, which clinicians need to be aware of and evaluate in patients with PCLD. In asymptomatic patients, no treatment is indicated for PCLD. In the symptomatic patient, surgical therapy is the mainstay of treatment tailored to the extent of disease for each patient. Management options include cyst aspiration and sclerosis, open or laparoscopic fenestration, liver resection with fenestration, and liver transplantation. The surgical literature discussing treatment of PCLD, including techniques, outcomes, and complication rates, are summarized in this review.Robert T Russell C Wright Pinson 2007World Journal of Gastroenterology2007,13,38:20

20Use of antibiotics in broiler production:Global impacts and alternatives显示文摘Antibiotics are used to fight bacterial infections.However, a selective pressure gave rise to bacteria resistant to antibiotics.This leaves scientists worried about the danger to human and animal health.Some strategies can be borrowed to reduce the use of antibiotics in chicken farms.Much research has been carried out to look for natural agents with similar beneficial effects of growth promoters.The aim of these alternatives is to maintain a low mortality rate, a good level of animal yield while preserving environment and consumer health.Among these, the most popular are probiotics, prebiotics, enzymes,organic acids, immunostimulants, bacteriocins, bacteriophages, phytogenic feed additives, phytoncides,nanoparticles and essential oils.Youcef Mehdi Marie-Pierre Létourneau-Montminy Marie-Lou Gaucher Younes Chorfi Gayatri Suresh Tarek Rouissi Satinder Kaur Brar Caroline Cté Antonio Avalos Ramirez Stéphane Godbout 2018Animal Nutrition2018,,2:19
