1Changes of the cytokine profile in inflammatory bowel diseases显示文摘Cytokines are indispensable signals of the mucosaassociated immune system for maintaining normal gut homeostasis.An imbalance of their profile in favour of inflammation initiation may lead to disease states,such as that is observed in inflammatory bowel diseases(IBD).Although Crohn's disease(CD) is often described as a prototype of T-helper 1-type diseases,and ulcerative colitis(UC) is traditionally viewed as a T-helper 2-mediated condition,the classic paradigm,which categorises cytokines into pro-and anti-inflammatory groups,has recently been changed.The inflammation regulatory pathways may not be mutually exclusive as individual cytokines can have diverse and even opposing functions in various clinical and immunological settings.None the less there are many common immunological responses in IBD that are mediated by cytokines.Although they regulate and influence the development,course and recurrence of the inflammatory process,the concrete pathogenic role of these small signaling molecules is sometimes not unambiguous in the subtypes of the disease.Our aim is to review the current information about pro-and anti-inflammatory effects of traditionally studied and recently discovered cytokines in the pathogenesis of UC and CD.The better understanding of their production and functional activity may lead to the development of new therapeutic modalities.Gyrgyi Mzes Béla Molnár Zsolt Tulassay Ferenc Sipos 2012World Journal of Gastroenterology2012,18,41:16
2Epithelial toll-like receptor 9 signaling in colorectal inflammation and cancer: Clinico-pathogenic aspects显示文摘Toll-like receptors (TLRs) recognize specific motifs which are frequently present in bacteria, fungi, prokaryotes and viruses. Amongst TLRs, TLR9 can be activated by such bacterial or viral DNA fragments, immunoglobulin-DNA complexes or synthetic oligonucleotides, which all contain unmethylated cytosineguanine nucleotide sequences (CpGs). Emerging data indicate that TLR9 signaling has a role in, and may influence, colorectal carcinogenesis and colonic inflammation. CpGs are classified into three groups according to their influence on both the antigen-specific humoraland cellular immunity, and the production of type 1 interferons and proinflammatory cytokines. TLR9 activation via CpGs may serve as a new therapeutic target for several cancerous and various inflammatory conditions. Due to its probable anti-cancer effects, the application possibilities of TLR9-signaling modulation may be extremely diverse even in colorectal tumors. In this review we aimed to summarize the current knowledge about TLR-signaling in the pathogenesis and therapy of inflammatory bowel diseases and colorectal cancer. Due to the species-specific differences in TLR9 expression, however, one must be careful in translating the animal model data into the human system, because of the differences between CpG-oligodeoxynucleotide-responsive cells. TLR9 agonist DNA-based immunomodulatory sequences could also represent a promising therapeutic alternative in systemic inflammatory conditions and chronic colonic inflammations as their side effects are not significant.István Fri Ferenc Sipos Tiana M Germann Alexandra Kalmár Zsolt Tulassay Béla Molnár Gyrgyi Mzes 2013World Journal of Gastroenterology2013,19,26:14

4非诺贝特治疗与2型糖尿病患者长期心血管病风险的关系显示文摘2型糖尿病患者心血管病风险高,部分原因在于高三酰甘油和低高密度脂蛋白胆固醇血症。而在他汀类药物治疗基础上,加强降低三酰甘油治疗,能否降低这种风险尚不清楚。该研究的目的是在使用他汀类药物治疗的2型糖尿病患者中,确定非诺贝特能否降低心血管病风险。刘莉 叶鹏 Elam MB Ginsberg HN Lovato LC Corson M Largay J Leiter LA Lopez C O'Connor PJ Sweeney ME Weiss D Friedewald WT Buse JB Gerstein HC Probstfield J Grimm R Ismail-Beigi F Goff DC Jr Fleg JL Rosenberg Y Byington RP ACCORDION study investigators 2017中华高血压杂志2017,25,6:7
5Regulatory T cells in inflammatory bowel diseases and colorectal cancer显示文摘Regulatory T cells(T regs) are key elements in immunological self-tolerance.The number of T regs may alter in both peripheral blood and in colonic mucosa during pathological circumstances.The local cellular,microbiological and cytokine milieu affect immunophenotype and function of T regs.Forkhead box P3+ T regs function shows altered properties in inflammatory bowel diseases(IBDs).This alteration of T regs function can furthermore be observed between Crohn's disease and ulcerative colitis,which may have both clinical and therapeutical consequences.Chronic mucosal inflammation may also influence T regs function,which together with the intestinal bacterial flora seem to have a supporting role in colitis-associated colorectal carcinogenesis.T regs have a crucial role in the immunoevasion of cancer cells in sporadic colorectal cancer.Furthermore,their number and phenotype correlate closely with the clinical outcome of the disease,even if their contribution to carcinogenesis has previously been controversial.Despite knowledge of the clinical relationship between IBD and colitis-associated colon cancer,and the growing number of immunological aspects encompassing sporadic colorectal carcinogenesis,the molecular and cellular links amongst T regs,regulation of the inflammation,and cancer development are still not well understood.In this paper,we aimed to review the current data surrounding the role of T regs in the pathogenesis of IBD,colitis-associated colon cancer and sporadic colorectal cancer.Gyrgyi Mzes Béla Molnár Ferenc Sipos 2012World Journal of Gastroenterology2012,18,40:7
6Quality of life, work productivity impairment and healthcare resources in inflammatory bowel diseases in Brazil显示文摘BACKGROUND Inflammatory bowel diseases(IBD)have been associated with a low quality of life(QoL)and a negative impact on work productivity compared to the general population.Information about disease control,patient-reported outcomes(PROs),treatment patterns and use of healthcare resources is relevant to optimizing IBD management.AIM To describe QoL and work productivity and activity impairment(WPAI),treatment patterns and use of healthcare resources among IBD patients in Brazil.METHODS A multicenter cross-sectional study included adult outpatients who were previously diagnosed with moderate to severe Crohn’s disease(CD)or ulcerative colitis(UC).At enrolment,active CD and UC were defined as having a Harvey Bradshaw Index≥8 or a CD Activity Index≥220 or calprotectin>200μg/g or previous colonoscopy results suggestive of inadequate control(per investigator criteria)and a 9-point partial Mayo score≥5,respectively.The PRO assessment included the QoL questionnaires SF-36 and EQ-5D-5L,the Inflammatory Bowel Disease Questionnaire(IBDQ),and the WPAI questionnaire.Information about healthcare resources and treatment during the previous 3 years was collected from medical records.Chi-square,Fisher’s exact and Student’s t-/Mann-Whitney U tests were used to compare PROs,treatment patterns and the use of healthcare resources by disease activity(α=0.05).RESULTS Of the 407 patients in this study(CD/UC:64.9%/35.1%,mean age 42.9/45.9 years,54.2%/56.6%female,38.3%/37.1%employed),44.7%/25.2%presented moderate-to-severe CD/UC activity,respectively,at baseline.Expressed in median values for CD/UC,respectively,the SF-36 physical component was 46.6/44.7 and the mental component was 45.2/44.2,the EQ-visual analog scale score was 80.0/70.0,and the IBDQ overall score was 164.0/165.0.Moderate to severe activity,female gender,being unemployed,a lower educational level and lower income were associated with lower QoL(P<0.05).Median work productivity impairment was 20%and 5%for CD and UC patients,respectively,and activity impairment was 30%,the latter being higher among patients with moderate to severe disease activity compared to patients with mild or no disease activity(75.0%vs 10.0%,P<0.001).For CD/UC patients,respectively,25.4%/2.8%had at least one surgery,38.3%/19.6%were hospitalized,and 70.7%/77.6%changed IBD treatment at least once during the last 3 years.The most common treatments at baseline were biologics(75.3%)and immunosuppressants(70.9%)for CD patients and 5-ASA compounds(77.5%)for UC patients.CONCLUSION Moderate to severe IBD activity,especially among CD patients,is associated with a substantial impact on QoL,work productivity impairment and an increased number of IBD surgeries and hospitalizations in Brazil.Rogerio Serafim Parra Julio MF Chebli Heda MBS Amarante Cristina Flores Jose ML Parente Odery Ramos Milene Fernandes Jose JR Rocha Marley R Feitosa Omar Feres Antonio S Scotton Rodrigo B Nones Murilo M Lima Cyrla Zaltman Carolina D Goncalves Isabella M Guimaraes Genoile O Santana Ligia Y Sassaki Rogerio S Hossne Mauro Bafutto Roberto LK Junior Mikaell AG Faria Sender J Miszputen Tarcia NF Gomes Wilson R Catapani Anderson A Faria Stella CS Souza Rosana F Caratin Juliana T Senra Maria LA Ferrari 2019World Journal of Gastroenterology2019,25,38:2

11西印度洋地区海草生态系统显示文摘海草是海洋被子植物,广泛分布在温带和热带的海岸带水域,是地球上水生生态系统中最具生产力的生物之一。在西印度洋地区大概有13种海草,这些海草覆盖了12000kg海岸线的近岸柔软海底广大区域。海草床一般分布在潮间带和潮下带,有时向下延伸至40m,并经常出现在珊瑚礁和红树林附近。由于具有很高的初级生产力和复杂的栖息环境,海草供养了许多底栖生物和浮游生物。许多鱼类和贝类,包括那些具有商业价值的种类都被吸引到海草栖息地,将海草作为其食物来源和避难场所,特别是在它们的幼年期。分布在西印度洋海草床附近广泛而丰富的鱼类资源就足以说明这一点。这些鱼分别属于天竺鲷科、亚科、玻甲鱼科、银鲈科、虾虎鱼科、隆头鱼科、裸颊鲷科、笛鲷科、单角亚科、鹦嘴鱼科、科、篮子鱼科、海龙科和Teraponidae科。因此,西印度洋地区的海草生态系统无论对当地还是整个地区的渔业发展都是非常有价值的资源。尽管如此,与其他地区相比,该地区有关海草资源的研究还十分缺乏,而且大多数研究也都集中在植物多样性和生态学上。本文主要阐述西印度洋地区海草床研究现状,特别强调鱼类和渔业。目前,该课题的大多数研究主要是在东非海岸开展的,如肯尼亚,坦桑尼亚,莫桑比克以及南非东部地区,而在索马里和西印度洋地区的岛屿国家(塞舌尔、科摩罗、法属留尼旺岛、毛里求斯、马达加斯加等)此类研究却很少,有关海草鱼类生态系统的论文也少有发表,而且大部分都是描述性的。因此,需要通过研究和实验获得有关描述模式和处理方法的科学知识。关于海草鱼类群落的定量研究,类似本文所介绍的案例研究在西印度洋地区是很少的,而这些研究对于渔业的管理前景而言是必不可少的。值得强调的是由于海岸人口的不断增长以及人类活动的侵扰给该地区海草床带来的压力与日俱增,如污染,海水富营养化,沉积作用,捕鱼以及无脊椎动物的采集等活动,而这些活动对于海草床的影响却鲜为人知。因此,需要开展广泛的研究,为西印度洋地区海草生态系统可持续管理提供有用的信息服务。Martin Gullstrm Maricela de la Torre Castro Salomo O.Bandeira Mats Bjrk Mattis Dahlberg Nils Kautsky Patrik Rnnbck Marcus C.hman 章任群 2002AMBIO-人类环境杂志2002,31,7:2
12Involvement of serum retinoids and Leiden mutation in patients with esophageal, gastric, liver, pancreatic, and colorectal cancers in Hungary显示文摘AIM: To analyze the serum levels of retinoids and Leiden mutation in patients with esophageal, gastric, liver,pancreatic, and colorectal cancers.METHODS: The changes in serum levels of retinoids (vitamin A, α- and β-carotene, α- and β-cryptoxanthin,zeaxanthin, lutein) and Leiden mutation were measured by high liquid performance chromatography (HPLC)and polymerase chain reaction (PCR) in 107 patients (70 males/37 females) with esophageal (0/8), gastric (16/5), liver (8/7), pancreatic (6/4), and colorectal (30/21including 9 patients suffering from in situ colon cancer)cancer. Fifty-seven healthy subjects (in matched groups)for controls of serum retinoids and 600 healthy blood donors for Leiden mutation were used.RESULTS: The serum levels of vitamin A and zeaxanthin were decreased significantly in all groups of patients with gastrointestinal (GI) tumors except for vitamin A in patients with pancreatic cancer. No changes were obtained in the serum levels of α- and β-carotene,α- and β-cryptoxanthin, zeaxanthin, lutein in patients with GI cancer. The prevalence of Leiden mutation significantly increased in all groups of patients with GI cancer.CONCLUSION: Retinoids (as environmental factors)are decreased significantly with increased prevalence of Leiden mutation (as a genetic factor) in patients before the clinical manifestation of histologically different (planocellular and hepatocellular carcinoma, and adenocarcinoma) GI cancer.Gyula Mózsik Gy(o|¨)rgy Rumi András D(o|¨)m(o|¨)t(o|¨)r Mária Figler Beáta Gasztonyi El(?)d Papp Alajos Pár Gabriella Pár József Belágyi Zoltán Matus Béla Melegh 2005World Journal of Gastroenterology2005,11,48:2
13Interaction of the major inflammatory bowel disease susceptibility alleles in Crohn’s disease patients显示文摘AIM:To investigate the interaction of interleukin-23 receptor(IL23R)(rs1004819 and rs2201841),autophagy-related 16-like 1(ATG16L1)(rs2241880), caspase recruitment domain-containing protein 15 (CARD15)genes,and IBD5 locus in Crohn's disease(CD) patients. METHODS:A total of 315 unrelated subjects with CD and 314 healthy controls were genotyped.Interactions and specific genotype combinations of a total of eight variants were tested.The variants of IBD5locus(IGR2198a_1 rs11739135 and IGR2096a_1 rs12521868),CARD15(R702W rs2066845 and L1007fs rs2066847),ATG16L1(rs2241880)and IL23R (rs1004819,rs2201841)genes were genotyped by PCR-RFLP,the G908R(rs2066844)in CARD15 was determined by direct sequencing. RESULTS:The association of ATG16L1 T300A with CD was confirmed[P=0.004,odds ratio(OR)=1.69, 95%CI:1.19-2.41],and both IL23R variants were found to represent significant risk for the disease(P= 0.008,OR=2.05,95%CI:1.20-3.50 for rs1004819 AA;P<0.001,OR=2.97,95%CI:1.65-5.33 for rs2201841 CC).Logistic regression analysis of pairwise interaction of the inflammatory bowel disease (IBD)loci indicated that IL23R,ATG16L1,CARD15 and IBD5(IGR2198a_1)contribute independently to disease risk.We also analysed the specific combina- tions by pair of individual ATG16L1,IL23R rs1004819, rs2201841,IGR2198a_1,IGR2096a_1 and CARD15 genotypes for disease risk influence.In almost all cases,the combined risk of susceptibility pairs was higher in patients carrying two different risk-associated gene variants together than individuals with just one polymorphism.The highest OR was found for IL23R rs2201841 homozygous genotype with combination of positive CARD15 status(P<0.001,OR=9.15,95% CI:2.05-40.74). CONCLUSION:The present study suggests a cumulative effect of individual IBD susceptibility loci.Veronika Csngei Luca Járomi EnikSáfrány Csilla Sipeky Lili Magyari Bernadett Faragó Judit Bene Noémi Polgár Lilla Lakner Patrícia Sarlós Márta Varga Béla Melegh 2010World Journal of Gastroenterology2010,16,2:2

15Competition between fusion-evaporation and multifragmentation in central collisions in ^(58)Ni+^(48)Ca at 25A MeV显示文摘The experimental data concerning the58Ni+48Ca reaction at Elab(Ni)=25A MeV,collected by using the CHIMERA 4π device,have been analyzed in order to investigate the competition among different reaction mechanisms for central collisions in the Fermi energy domain.As a main criterion for centrality selection we have chosen the flow angle(flow) method,making an event-by-event analysis that considers the shape of events,as it is determined by the eigenvectors of the experimental kinetic-energy tensor.For the selected central events(flow >60°) some global variables,good to characterize the pattern of central collisions have been constructed.The main features of the reaction products were explored by using different constraints on some of the relevant observables,like mass and velocity distributions and their correlations.Much emphasis was devoted,for central collisions,to the competition between fusion-evaporation processes with subsequent identification of a heavy residue and a possible multifragmentation mechanism of a well defined(if any) transient nuclear system.Dynamical evolution of the system and pre-equilibrium emission were taken into account by simulating the reactions in the framework of transport theories.Different approaches have been envisaged(dynamical stochastic BNV calculations + sequential SIMON code,QMD,CoMD,etc.).Preliminary comparison of the experimental data with BNV calculations shows reasonable agreement with the assumption of sequential multifragmentation emission in the mass region of IMFs close to the heavy residues.Possible deviations from sequential processes were found for those IMFs in the region of masses intermediate between the mass of heavy residues and the mass of light IMFs.Further simulations are in progress.The experimental analysis will be enriched also by information obtained inspecting the IMF-IMF correlation function,in order to elucidated the nature of space-time decay property of the emitting source associated with events having the largest IMF multiplicity.FRANCALANZA L ABBONDANNO U AMORINI F BARLINI S BINI M BOUGAULT R BRUNO M CARDELLA G CASINI G AGOSTINO M D' De FILIPPO V De SANCTIS J GERACI E GIUSSANI A GRAMEGNA F GUIOT B KRAVCHUK V La GUIDARA E LANZALONE G Le NEINDRE N MAIOLINO C MARINI P MORELLI L OLMI A PAGANO A PAPA M PIANTELLI S PIRRONE S POLITI G POGGI G PORTO F RUSSOTTO P RIZZO F VANNINI G VANNUCCI L 2013Nuclear Science and Techniques2013,24,5:2
