| 1 | MicroRNAs as a potential prognostic factor in gastric cancer显示文摘AIM:To compare the microRNA (miR) profiles in the primary tumor of patients with recurrent and non-recurrent gastric cancer.METHODS:The study group included 45 patients who underwent curative gastrectomies from 1995 to 2005 without adjuvant or neoadjuvant therapy and for whom adequate tumor content was available.Total RNA was extracted from formalin-fixed paraffin-embedded tumor samples,preserving the small RNA fraction.Initial profiling using miR microarrays was performed to identify potential biomarkers of recurrence after resection.The expression of the differential miRs was later verified by quantitative real-time polymerase chain reaction (qRT-PCR).Findings were compared between patients who had a recurrence within 36 mo of surgery (bad-prognosis group,n=14,31%) and those who did not (good-prognosis group,n=31,69%).RESULTS:Three miRs,miR-451,miR-199a-3p and miR-195 were found to be differentially expressed in tumors from patients with good prognosis vs patients with bad prognosis (P<0.0002,0.0027 and 0.0046 respectively).High expression of each miR was associated with poorer prognosis for both recurrence and survival.Using miR-451,the positive predictive value for non-recurrence was 100% (13/13).The expression of the differential miRs was verified by qRT-PCR,showing high correlation to the microarray data and similar separation into prognosis groups.CONCLUSION:This study identified three miRs,miR-451,miR-199a-3p and miR-195 to be predictive of recurrence of gastric cancer.Of these,miR-451 had the strongest prognostic impact. | Baruch Brenner Moshe B Hoshen Ofer Purim Miriam Ben David Karin Ashkenazi Gideon Marshak Yulia Kundel Ronen Brenner Sara Morgenstern Marisa Halpern Nitzan Rosenfeld Ayelet Chajut Yaron Niv Michal Kushnir | 2011 | World Journal of Gastroenterology2011，17，35： | 31 |

| 3 | Infectious burden and atherosclerosis: A clinical issue显示文摘Atherosclerotic cardiovascular diseases, chronic inflam-matory diseases of multifactorial etiology, are the lead-ing cause of death worldwide. In the last decade, more infectious agents, labeled as 'infectious burden', rather than any single pathogen, have been showed to con-tribute to the development of atherosclerosis through different mechanisms. Some microorganisms, such as Chlamydia pneumoniae(C. pneumoniae), human cytomegalovirus, etc. may act directly on the arterial wall contributing to endothelial dysfunction, foam cell formation, smooth muscle cell proliferation, platelet ag-gregation as well as cytokine, reactive oxygen specie, growth factor, and cellular adhesion molecule produc-tion. Others, such as Helicobacter pylori(H. pylori), in-fluenza virus, etc. may induce a systemic inflammation which in turn may damage the vascular wall(e.g., by cytokines and proteases). Moreover, another indirect mechanism by which some infectious agents(such as H. pylori, C. pneumoniae, periodontal pathogens, etc.) may play a role in the pathogenesis of atherosclero-sis is molecular mimicry. Given the complexity of the mechanisms by which each microorganism may con-tribute to atherosclerosis, defining the interplay of moreinfectious agents is far more difficult because the pro-atherogenic effect of each pathogen might be ampli-fied. Clearly, continued research and a greater aware-ness will be helpful to improve our knowledge on the complex interaction between the infectious burden and atherosclerosis. | Rosa Sessa Marisa Di Pietro Simone Filardo Ombretta Turriziani | 2014 | World Journal of Clinical Cases2014，2，7： | 17 |

| 5 | Endoscopic ultrasound staging for early esophageal cancer: Are we denying patients neoadjuvant chemo-radiation?显示文摘AIM To evaluate the accuracy of endoscopic ultrasound(EUS) in early esophageal cancer(EC) performed in a highvolume tertiary cancer center. METHODS A retrospective review of patients undergoing esophagectomy was performed and patients with c T1 N0 and c T2 N0 esophageal cancer by EUS were evaluated. Patient demographics, tumor characteristics, and treatment were reviewed. EUS staging was compared to surgical pathology to determine accuracy of EUS. Descriptive statistics was used to describe the cohort. Student's t test and Fisher's exact test or χ~2 test was used to compare variables. Logistic regression analysis was used to determine if clinical variables such as tumor location and tumor histology were associated with EUS accuracy.RESULTS Between 2000 and 2015, 139 patients with clinical stage Ⅰ or Ⅱ?A esophageal cancer undergoing esophagectomy were identified. There were 25(18%) female and 114(82%) male patients. The tumor location included the middle third of the esophagus in 11(8%) and lower third and gastroesophageal junction in 128(92%) patients. Ninety-three percent of patients had adenocarcinoma. Preoperative EUS matched the final surgical pathology in 73/139 patients for a concordance rate of 53%. Twenty-nine patients(21%) were under-staged by EUS; of those, 19(14%) had unrecognized nodal disease. Positron emission tomography(PET) was used in addition to EUS for clinical staging in 62/139 patients. Occult nodal disease was only found in 4 of 62 patients(6%) in whom both EUS and PET were negative for nodal involvement. CONCLUSION EUS is less accurate in early EC and endoscopic mucosal resection might be useful in certain settings. The addition of PET to EUS improves staging accuracy. | Carrie Luu Marisa Amaral Jason Klapman Cynthia Harris Khaldoun Almhanna Sarah Hoffe Jessica Frakes Jose M Pimiento Jacques P Fontaine | 2017 | World Journal of Gastroenterology2017，23，46： | 8 |
| 6 | Cancer stem cells in colorectal cancer from pathogenesis to therapy: Controversies and perspectives显示文摘Colorectal cancer remains one of the most common and lethal malignancies worldwide despite the use of various therapeutic strategies.A better understanding of the mechanisms responsible for tumor initiation and progression is essential for the development of novel,more powerful therapies.The traditional,so-called'stochastic model'of tumor development,which assumes that each cancer cell is tumorigenic,has been deeply challenged during the past decade by the identification of cancer stem cells(CSCs),a biologically distinct subset of cells within the bulk of tumor mass.This discovery led to the development of the hierarchical model of tumorigenesis which assumes that only CSCs have the ability to initiate tumor growth,both at primary and metastatic sites.This model implies that the elimination of all CSCs is fundamental to eradicate tumors and that failure to do so might be responsible for the occurrence of relapses and/or metastases frequently observed in the clinical management of colorectal cancer patients.Identification and isolation of CSCs is essential for a better understanding of their role in the tumorigenetic process and for the development of CSC-specific therapies.Several methods have been used for this purpose and many efforts have been focused on the identification of specific CSC-surface markers.This review provides an overview of the proposed roles of CSC in human colorectal tumorigenesis focusing on the most important molecules identified as CSC-specific markers in colorectal cancer and on the potential strategies for the development of CSC-targeted therapy. | Caterina Fanali Donatella Lucchetti Marisa Farina Maddalena Corbi Valerio Cufino Achille Cittadini Alessandro Sgambato | 2014 | World Journal of Gastroenterology2014，20，4： | 7 |
| 7 | Management of cholelithiasis in Italian children:A national multicenter study显示文摘AIM:To evaluate the management of Italian children with cholelithiasis observed at Pediatric and Surgical Departments linked to Italian Society of Pediatric Gastroenterology Hepatology and Nutrition. METHODS: One-hundred-eighty children (90 males, median age at diagnosis 7.3 years; range, 0-18 years) with echographic evidence of cholelithiasis were enrolled in the study; the data were collected by an anonymous questionnaire sent to participating centers. RESULTS: One hundred seventeen patients were treated with ursodeoxycholic acid; in 8 children dissolution of gallstones was observed, but the cholelithiasis recurred in 3 of them. Sixty-five percent of symptomatic children treated became asymptomatic. Sixty-four patients were treated with cholecystectomy and in only 2 cases a postoperative complication was reported. Thirty- four children received no treatment and were followed with clinical and echographic controls; in no case thedevelopment of complications was reported. CONCLUSION: The therapeutic strategies were extremely heterogeneous. Ursodeoxycholic acid was ineffective in dissolution of gallstones but it had a positive effect on the symptoms. Laparoscopic cholecystectomy was confirmed to be an efficacy and safe treatment for pediatric gallstones. | Claudia Della Corte Diego Falchetti Gabriella Nebbia Marisa Calacoci Maria Pastore Ruggiero Francavilla Matilde Marcellini Pietro Vajro Raffaele Iorio | 2008 | World Journal of Gastroenterology2008，14，9： | 6 |

| 9 | Short-term effectiveness of golimumab for ulcerative colitis: Observational multicenter study显示文摘AIM To evaluate the real-world effectiveness of golimumab in ulcerative colitis(UC) and to identify predictors of response.METHODS We conducted an observational, prospective and multi-center study in UC patients treated with golimumab, from September 2014 to September 2015. Clinical activity was assessed at wk 0 and 14 with the physician's global clinical assessment(PGA) and the partial Mayo score. Colonoscopies and blood tests were performed, following daily-practice clinical criteria, and the results were recorded in an SPSS database.RESULTS Thirty-three consecutive patients with moderately to severely active UC were included. Among them, 54.5% were female and 42 years was the average age. Thirty percent had left-sided UC(E2) and 70% had extensive UC(E3). All patients had an endoscopic Mayo score of 2 or 3 at baseline. Twenty-seven point three percent were anti-tumor necrosis factor(TNF) treatment na?ve, whereas 72.7% had previously received infliximab and/or adalimumab. Sixty-nine point seven percent showed clinical response and were steroid-free at wk 14(a decrease from baseline in the partial Mayo score of at least 3 points). Based on PGA, the clinical remission and clinical response rates were 24% and 55% respectively. Withdrawal of corticosteroids was observed in 70.8% of steroid-dependent patients at the end of the study. Three out of 10 clinical non-responders needed a colectomy. Mean fecal calprotectin value at baseline was 300 μg/g, and 170.5 μg/g at wk 14. Being anti-TNF treatment na?ve was a protection factor, which was related to better chances of reaching clinical remission. Twenty-seven point three percent of the patients required treatment intensification at 14 wk of followup. Only three adverse effects(AEs) were observed during the study; all were mild and golimumab was not interrupted.CONCLUSION This real-life practice study endorses golimumab's promising results, demonstrating its short-term effectiveness and confirming it as a safe drug during the induction phase. | Marta Maia Bosca-Watts Xavier Cortes Marisa Iborra Jose Maria Huguet Laura Sempere Gloria Garcia Rafa Gil Mari Fe Garcia Marga Munoz Pedro Almela Nuria Maroto Jose Maria Paredes | 2016 | World Journal of Gastroenterology2016，22，47： | 5 |
| 10 | Gastric mucin expression in Helicobacter pylori-related, nonsteroidal anti-inflammatory drug-related and idiopathic ulcers显示文摘AIM: To determine the pattern of secreted mucin expression in Helicobacter pylori (H. pylori)-related, nonsteroidal anti-inflammatory drug (NSAID)-related and idiopathic gastric ulcers. METHODS: We randomly selected 92 patients with H. pylori-associated (n = 30), NSAID-associated (n = 18), combined H. pylori and NSAID-associated gastric ulcers (n = 24), and patients with idiopathic gastric ulcers (n = 20). Immunohistochemistry for T-cell CD4/CD8, andfor mucin 5AC (MUC5AC) and mucin 6 (MUC6), was performed on sections of the mucosa from the ulcer margin. Inflammation score was assessed according to the Sydney system. RESULTS: MUC5AC was expressed on the surface epithelium (98.9%) and neck glands (98.9%) with minimal expression in the deep glands (6.5%). MUC6 was strongly expressed in the deep glands (97.8%), variable in the neck glands (19.6%) and absent in the surface epithelium (0%). The pattern of mucin expression in idiopathic ulcer margins was not different from the expression in ulcers associated with H. pylori, NSAIDs, or combined H. pylori and NSAIDs. CD4/CD8 ratio was higher in H. pylori-positive patients (P = 0.009). Idiopathic ulcers are associated with hospitalized patients and have higher bleeding and mortality rates. CONCLUSION: Idiopathic ulcers have a unique clinical profile. Gastric mucin expression in idiopathic gastric ulcers is unchanged compared with H. pylori and/or NSAID-associated ulcers. | Doron Boltin Marisa Halpern Zohar Levi Alex Vilkin Sara Morgenstern Samuel B Ho Yaron Niv | 2012 | World Journal of Gastroenterology2012，18，33： | 5 |
| 11 | MGMT and MLH1 methylation in Helicobacter pylori-infected children and adults显示文摘AIM:To evaluate the association between Helicobacter pylori(H.pylori) infection and MLH1 and MGMT methylation and its relationship with microsatellite instability(MSI).METHODS:The methylation status of the MLH1 and MGMT promoter region was analysed by methylation specific methylation-polymerase chain reaction(MSPPCR) in gastric biopsy samples from uninfected or H.pylori-infected children(n = 50),from adults with chronic gastritis(n = 97) and from adults with gastric cancer(n = 92).MLH1 and MGMT mRNA expression were measured by real-time PCR and normalised to a constitutive gene(β actin).MSI analysis was performed by screening MSI markers at 4 loci(Bat-25,Bat-26,D17S250 and D2S123) with PCR;PCR products were analysed by single strand conformation polymorphism followed by silver staining.Statistical analyses were performed with either the χ 2 test with Yates continuity correction or Fisher's exact test,and statistical significance for expression analysis was assessed using an unpaired Student's t-test.RESULTS:Methylation was not detected in the promoter regions of MLH1 and MGMT in gastric biopsy samples from children,regardless of H.pylori infection status.The MGMT promoter was methylated in 51% of chronic gastritis adult patients and was associated with H.pylori infection(P < 0.05);this region was methylated in 66% of gastric cancer patients,and the difference in the percentage of methylated samples between these patients and those from H.pylori-infected chronic gastritis patients was statistically significant(P < 0.05).MLH1 methylation frequencies among H.pylori-infected and non-infected chronic gastritis adult patients were 13% and 7%,respectively.We observed methylation of the MLH1 promoter(39%) and increased MSI levels(68%) in samples from gastric cancer patients in comparison to samples from H.pylori-infected adult chronic gastritis patients(P < 0.001 and P < 0.01,respectively).The frequency of promoter methylation for both genes was higher in gastric cancer samples than in H.pylori-positive chronic gastritis samples(P < 0.05).The levels of MLH1 and MGMT mRNA were significantly reduced in chronic gastritis samples that were also hypermethylated(P < 0.01).CONCLUSION:In summary,MGMT and MLH1 methylation did not occur in earlier-stage H.pylori infections and thus might depend on the duration of infection. | Marisa C Alvarez Juliana C Santos Nathália Maniezzo Marcelo S Ladeira Artur LC da Silva Isabel CA Scaletsky José Pedrazzoli Jr Marcelo L Ribeiro | 2013 | World Journal of Gastroenterology2013，19，20： | 5 |
| 12 | Membrane-bound mucins and mucin terminal glycans expression in idiopathic or Helicobacter pylori, NSAID associated peptic ulcers显示文摘AIM:To determine the expression of membrane-bound mucins and glycan side chain sialic acids in Helicobacter pylori(H.pylori)-associated,non-steroidal inflammatory drug(NSAID)-associated and idiopathic-gastric ulcers.METHODS:We studied a cohort of randomly selected patients with H.pylori(group 1,n=30),NSAID(group 2,n=18),combined H.pylori and NSAID associated gastric ulcers(group 3,n=24),and patients with idiopathic gastric ulcers(group 4,n=20).Immunohistochemistry for MUC1,MUC4,MUC17,and staining for Erythrina cristagalli agglutinin and Sambucus nigra agglutinin(SNA)lectins was performed on sections from the ulcer margins.RESULTS:Staining intensity of MUC17 was higher in H.pylori ulcers(group 1)than in idiopathic ulcers(group4),11.05±3.67 vs 6.93±4.00 for foveola cells,and10.29±4.67 vs 8.00±3.48 for gland cells,respectively(P<0.0001).In contrast,MUC1 expression was higher in group 4 compared group 1,9.89±4.17 vs 2.93±5.13 in foveola cells and 7.63±4.60 vs 2.57±4.50 for glands,respectively(P<0.0001).SNA lectin staining was increased in group 4,in parallel to elevated MUC1expression,indicating more abundantα2-6 sialylation in that group.CONCLUSION:Cytoplasmic MUC17 staining was sig-nificantly decreased in the cases with idiopathic ulcer.The opposite was observed for both MUC1 and SNA lectin.This observation may reflect important pathogenic mechanisms,since different mucins with altered sialylation patterns may differ in their protection efficiency against acid and pepsin. | Yaron Niv Doron Boltin Marisa Halpern Miriam Cohen Zohar Levi Alex Vilkin Sara Morgenstern Vahig Manugian Erica St Lawrence Pascal Gagneux Sukhwinder Kaur Poonam Sharma Surinder K Batra Samuel B Ho | 2014 | World Journal of Gastroenterology2014，20，40： | 5 |

| 17 | Adalimumab in prevention of postoperative recurrence of Crohn's disease in high-risk patients显示文摘AIM:To evaluate the effectiveness of adalimumab in preventing recurrence after intestinal resection for Crohn's disease in high-risk patients.METHODS:A multicenter,prospective,observational study was conducted from June 2009 until June 2010.We consecutively included high-risk Crohn's disease patients who had undergone an ileal/ileocolonic resection.High-risk patients were defined as two or more criteria:smokers,penetrating pattern,one or more previous surgical resections or prior extensive resection.Subcutaneous adalimumab was administered 2 wk(± 5 d) after surgery at a dose of 40 mg eow,with an initial induction dose of 160/80 mg at weeks 0 and 2.Demographic data,previous and concomitant treatments(antibiotics,5-aminosalicylates,corticosteroids,immunomodulators or biologic therapies),smoking status at the time of diagnosis and after the index operation and number of previous resections(type and reason for surgery) were all recorded.Biological status was assessed with C-reactive protein,erythrocyte sedimentation rate and fecal calprotectin.One year(± 3 mo) after surgery,an ileocolonoscopy and/or magnetic resonance enterography was performed.Endoscopic recurrence was defined as Rutgeerts score ≥ i2.Morphological recurrence was based on magnetic resonance(MR) score ≥ MR1.RESULTS:Twenty-nine patients(55.2% males,48.3% smokers at diagnosis and 13.8% after the index operation),mean age 42.3 years and mean duration of the disease 13.8 years were included in the study.A mean of 1.76(range:1-4) resections previous to adalimumab administration and in 37.9% was considered extensive resection.51.7% had previously received infliximab.Immunomodulators were given concomitantly to 17.2% of patients.Four of the 29(13.7%) developed clinical recurrence,6/29(20.7%) endoscopic recurrence and 7/19(36.8%) morphological recurrence after 1-year.All patients with clinical recurrence showed endoscopic and morphological recurrence.A high degree of concordance was found between clinical-endoscopic recurrence(k = 0.76,P < 0.001) and clinical-morphological recurrence(k = 0.63,P = 0.003).Correlation between endoscopic and radiological findings was good(comparing the 5-point Rutgeerts score with the 4-point MR score,a score of i4 was classified as MR3,i3 as MR2,and i2-i1 as MR1)(P < 0.001,r s = 0.825).During follow-up,five(17.2%) patients needed adalimumab dose intensification(40 mg/wk);Mean time to intensification after the introduction of adalimumab treatment was 8 mo(range:5 to 11 mo).In three cases(10.3%),a biological change was needed due to a worsening of the disease after the dose intensification to 40 mg/wk.One patient suffered an adverse event.CONCLUSION:Adalimumab seems to be effective and safe in preventing postoperative recurrence in a selected group of patients who had undergone an intestinal resection for their CD. | Mariam Aguas Guillermo Bastida Elena Cerrillo Belén Beltrán Marisa Iborra Cristina Sánchez-Montes Fernando Muoz Jesús Barrio Sabino Riestra Pilar Nos | 2012 | World Journal of Gastroenterology2012，18，32： | 3 |
| 18 | Biosorption of mercury by Macrocystis pyrifera and Undaria pinnatifida:Influence of zinc,cadmium and nickel显示文摘This study investigated the adsorption of Hg(Ⅱ) on Macrocystis pyrifera and Undaria pinnatifida in monometallic system in the presence of Zn(II),Cd(Ⅱ) and Ni(II).The two biosorbents reached the same maximum sorption capacity (q m = 0.8 mmol/g) for mercury.U.pinnatifida showed a greater affinity (given by the coefficient b of the Langmuir equation) for mercury compared to M.pyrifera (4.4 versus 2.7 L/mmol).Mercury uptake was significantly reduced (by more than 50%) in the presence of competitor heavy metals such as Zn(II),Cd(II) and Ni(Ⅱ).Samples analysis using an environmental scanning electron microscopy equipped with an energy dispersive X-ray microanalysis showed that mercury was heterogeneously adsorbed on the surface of both biomaterials,while the other heavy metals were homogeneous distributed.The analysis of biosorbents by Fourier transform infrared spectrometry indicated that Hg(Ⅱ) binding occurred on S=O (sulfonate) and N-H (amine) functional groups. | Josefina Plaza Marisa Viera Edgardo Donati Eric Guibal | 2011 | Journal of Environmental Sciences2011，23，11： | 3 |
