1Schistosoma mansoni proteins attenuate gastrointestinal motility disturbances during experimental colitis in mice显示文摘AIM:To investigate the therapeutic effect of Schistosoma mansoni(S.mansoni) soluble worm proteins on gastrointestinal motility disturbances during experimental colitis in mice. METHODS:Colitis was induced by intrarectal injection of trinitrobenzene sulphate(TNBS) and 6 h later,mice were treated ip with S.mansoni proteins.Experiments were performed 5 d after TNBS injection.Inflammationwas quantified using validated inflammation parameters. Gastric emptying and geometric center were measured to assess in vivo gastrointestinal motility.Peristaltic activity of distal colonic segments was studied in vitro using a modified Trendelenburg set-up.Cytokine profiles of T-lymphocytes isolated from the colon were determined by real time reverse transcriptase-polymerase chain reaction. RESULTS:Intracolonic injection of TNBS caused severe colitis.Treatment with S.mansoni proteins significantly ameliorated colonic inflammation after 5 d.TNBS did not affect gastric emptying but significantly decreased the geometric center and impaired colonic peristaltic activity 5 d after the induction of colitis.Treatment with S.mansoni proteins ameliorated these in vivo and in vitro motility disturbances.In addition,TNBS injection caused a downregulation of effector T cell cytokines after 5 d,whereas a S.mansoni protein effect was no longer observed at this time point. CONCLUSION:Treatment with S.mansoni proteins attenuated intestinal inflammation and ameliorated motility disturbances during murine experimental colitis.Nathalie E Ruyssers Benedicte Y De Winter Joris G De Man Natacha D Ruyssers Ann J Van Gils Alex Loukas Mark S Pearson Joel V Weinstock Paul A Pelckmans Tom G Moreels 2010World Journal of Gastroenterology2010,16,6:11
2Near-infrared fluorescence sentinel lymph node detection in gastric cancer: A pilot study显示文摘AIM: To investigate feasibility and accuracy of nearinfrared fluorescence imaging using indocyanine green: nanocolloid for sentinel lymph node(SLN) detection in gastric cancer.METHODS: A prospective, single-institution, phaseI feasibility trial was conducted. Patients suffering from gastric cancer and planned for gastrectomy were included. During surgery, a subserosal injection of 1.6 m L ICG:Nanocoll was administered around the tumor. NIR fluorescence imaging of the abdominal cavity was performed using the Mini-FLARE? NIR fluorescence imaging system. Lymphatic pathways and SLNs were visualized. Of every detected SLN, the corresponding lymph node station, signal-to-background ratio and histopathological diagnosis was determined. Patients underwent standard-of-care gastrectomy. Detected SLNs outside the standard dissection planes were also resected and evaluated.RESULTS: Twenty-six patients were enrolled. Four patients were excluded because distant metastases were found during surgery or due to technical failure of the injection. In 21 of the remaining 22 patients, at least 1 SLN was detected by NIR Fluorescence imaging(mean 3.1 SLNs; range 1-6). In 8 of the 21 patients, tumor-positive LNs were found. Overall accuracy of the technique was 90%(70%-99%; 95%CI), which decreased by higher p T-stage(100%, 100%, 100%, 90%, 0% for respectively Tx, T1, T2, T3, T4 tumors). All NIR-negative SLNs were completely effaced by tumor. Mean fluorescence signal-to-background ratio of SLNs was 4.4(range 1.4-19.8). In 8 of the 21 patients, SLNs outside the standard resection plane were identified, that contained malignant cells in 2 patients.CONCLUSION: This study shows successful use of ICG:Nanocoll as lymphatic tracer for SLN detection in gastric cancer. Moreover, tumor-containing LNs outside the standard dissection planes were identified.Quirijn RJG Tummers Leonora SF Boogerd Wobbe O de Steur Floris PR Verbeek Martin C Boonstra Henricus JM Handgraaf John V Frangioni Cornelis JH van de Velde Henk H Hartgrink Alexander L Vahrmeijer 2016World Journal of Gastroenterology2016,22,13:9
3Near-infrared fluorescence imaging of a solitary fibrous tumor of the pancreas using methylene blue显示文摘A 67-year-old female presented with unexplained abdominal pain. A contrast-enhanced computed tomography scan of the abdomen incidentally revealed a mass in the uncinate process of the pancreas. This mass was resected and based on histopathological findings, diagnosed as a solitary fibrous tumor (SFT) of the pancreas. A SFT is an extremely rare benign mesenchymal tumor that in 65% of cases affects the visceral pleura but can also affect extra-pleural sites. The intraoperative demarcation of pancreatic tumors, such as SFTs, can bechallenging. In this report, the first clear intraoperative identification of a SFT of the pancreas in a human was shown using near-infrared fluorescence and methylene blue.Joost R van der Vorst Alexander L Vahrmeijer Merlijn Hutteman Tjalling Bosse Vincent THBM Smit Cornelis JH van de Velde John V Frangioni Bert A Bonsing 2012World Journal of Gastrointestinal Surgery2012,4,7:7

9Trends in treatment and overall survival among patients with proximal esophageal cancer显示文摘BACKGROUND The management of proximal esophageal cancer differs from that of tumors located in the mid and lower part of the esophagus due to the close vicinity of vital structures.Non-surgical treatment options like radiotherapy and definitive chemoradiation(CRT)have been implemented.The trends in(non-)surgical treatment and its impact on overall survival(OS)in patients with proximal esophageal cancer are unclear,related to its rare disease status.To optimize treatment strategies and counseling of patients with proximal esophageal cancer,it is therefore essential to gain more insight through real-life studies.AIM To establish trends in treatment and OS in patients with proximal esophageal cancer.METHODS In this population-based study,patients with proximal esophageal cancer diagnosed between 1989 and 2014 were identified in the Netherlands Cancer Registry.The proximal esophagus consists of the cervical esophagus and the upper thoracic section,extending to 24 cm from the incisors.Trends in radiotherapy,chemotherapy,and surgery,and OS were assessed.Analyses were stratified by presence of distant metastasis.Multivariable Cox proportional hazards regression analyses was performed to assess the effect of period of diagnosis on OS,adjusted for patient,tumor,and treatment characteristics.RESULTS In total,2783 patients were included.Over the study period,the use of radiotherapy,resection,and CRT in non-metastatic disease changed from 53%,23%,and 1%in 1989-1994 to 21%,9%,and 49%in 2010-2014,respectively.In metastatic disease,the use of chemotherapy and radiotherapy increased over time.Median OS of the total population increased from 7.3 mo[95%confidence interval(CI):6.4-8.1]in 1989-1994 to 9.5 mo(95%CI:8.1-10.8)in 2010-2014(logrank P<0.001).In non-metastatic disease,5-year OS rates improved from 5%(95%CI:3%-7%)in 1989-1994 to 13%(95%CI:9%-17%)in 2010-2014(logrank P<0.001).Multivariable regression analysis demonstrated a significant treatment effect over time on survival.In metastatic disease,median OS was 3.8 mo(95%CI:2.5-5.1)in 1989-1994,and 5.1 mo(95%CI:4.3-5.9)in 2010-2014(logrank P=0.26).CONCLUSION OS significantly improved in non-metastatic proximal esophageal cancer,likely to be associated with an increased use of CRT.Patterns in metastatic disease did not change significantly over time.Judith de Vos-Geelen Sandra ME Geurts Liselot BJ Valkenburg-van Iersel Evelien JM de Jong Vivianne CG Tjan-Heijnen Margreet van Putten Valery EPP Lemmens Heike I Grabsch Nadia Haj Mohammad Frank JP Hoebers Chantal V Hoge Paul M Jeene Hanneke WM van Laarhoven Tom Rozema Marije Slingerland Grard AP Nieuwenhuijzen 2019World Journal of Gastroenterology2019,25,47:2

11遗传性肥胖与心房颤动的关系显示文摘观察性研究已经确定了体质量指数(body mass index,BMI)与心房颤动之间的关联。然而,从观察性研究中推断因果关系会受到混杂因素、逆因果关系和偏倚的影响。该研究的主要目的是应用BMI的遗传学预测因子评估BMI与心房颤动之间的因果关系。方法:纳入1987-2002年期间在美国、冰岛和荷兰实施的7个前瞻性人群队列研究中基线无心房颤动的欧洲血统个体51 646人,刘莉 叶鹏 Chatterjee NA Giulianini F Geelhoed B Lunetta KL Misialek JR Niemeijer MN Rienstra M Rose LM Smith AV Arking DE Ellinor PT Heeringa J Lin H Lubitz SA Soliman EZ Verweij N Alonso A Benjamin EJ Gudnason V Stricker BH van der Harst P Chasman DI Albert CM 2017中华高血压杂志2017,25,2:2
12Exploiting the diversity of tomato:the development of a phenotypically and genetically detailed germplasm collection显示文摘A collection of 163 accessions,including Solanum pimpinellifolium,Solanum lycopersicum var.cerasiforme and Solanum lycopersicum var.lycopersicum,was selected to represent the genetic and morphological variability of tomato at its centers of origin and domestication:Andean regions of Peru and Ecuador and Mesoamerica.The collection is enriched with S.lycopersicum var.cerasiforme from the Amazonian region that has not been analyzed previously nor used extensively.The collection has been morphologically characterized showing diversity for fruit,flower and vegetative traits.Their genomes were sequenced in the Varitome project and are publicly available(solgenomics.net/projects/varitome).The identified SNPs have been annotated with respect to their impact and a total number of 37,974 out of 19,364,146 SNPs have been described as high impact by the SnpEeff analysis.GWAS has shown associations for different traits,demonstrating the potential of this collection for this kind of analysis.We have not only identified known QTLs and genes,but also new regions associated with traits such as fruit color,number of flowers per inflorescence or inflorescence architecture.To speed up and facilitate the use of this information,F2 populations were constructed by crossing the whole collection with three different parents.This F2 collection is useful for testing SNPs identified by GWAs,selection sweeps or any other candidate gene.All data is available on Solanaceae Genomics Network and the accession and F2 seeds are freely available at COMAV and at TGRC genebanks.All these resources together make this collection a good candidate for genetic studies.Estefanía Mata-Nicolás Javier Montero-Pau Esther Gimeno-Paez Víctor Garcia-Carpintero Peio Ziarsolo Naama Menda Lukas A.Mueller JoséBlanca Joaquín Cañizares Esther van der Knaap María JoséDíez 2020Horticulture Research2020,7,1:2
