| 1 | -765G > C COX-2 polymorphism may be a susceptibility marker for gastric adenocarcinoma in patients with atrophy or intestinal metaplasia显示文摘AIM: To investigate the relationship between the -765G > C COX-2 polymorphism and the development of different gastric lesions: atrophy or intestinal metaplasia and gastric adenocarcinoma. METHODS: A cross-sectional study was performed involving 320 Portuguese individuals (210 without evidence of neoplastic disease, 73 patients with gastric adenocarcinomas and 37 with atrophy or intestinal metaplasia) using a PCR-RFLP method. RESULTS: -765C allele was overrepresented in the patients with gastric adenocarcinoma (51%) when compared either with the control group (38%) or patients with atrophy or intestinal metaplasia (27%). Callele was found to be very common in our population (0.22), and a multivariate logistic regression analysis revealed nearly 3-fold increased risk for the progression to gastric adenocarcinoma in patients with atrophy or intestinal metaplasia carrying the -765C allele (OR = 2.67, 95% CI = 1.03-6.93; P = 0.04).considered as another susceptibility marker for gastric adenocarcinoma development in patients with atrophy or intestinal metaplasia. | Carina Pereira Hugo Sousa Paula Ferreira Maria Fragoso Luís Moreira-Dias Carlos Lopes Rui Medeiros Mário Dinis-Ribeiro | 2006 | World Journal of Gastroenterology2006，12，34： | 16 |
| 2 | Treatment modalities for early gastric cancer显示文摘Different treatment modalities have been proposed in the treatment of early gastric cancer(EGC). Endoscopic resection(ER) is an established treatment that allows curative treatment, in selected cases. In addition, ER allows for an accurate histological staging, which is crucial when deciding on the best treatment option for EGC. Recently, endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD) have become alternatives to surgery in early gastric cancer, mainly in Asian countries. Patients with 'standard' criteria can be successfully treated by EMR techniques. Those who meet 'expanded' criteria may benefit from treatment by ESD, reducing the need for surgery. Standardized ESD training system is imperative to promulgate effective and safe ESD technique to practices with limited expertise. Although endoscopic resection is an option in patients with EGC, surgical treatment continues to be a widespread therapeutic option worldwide. In this review we tried to point out the treatment modalities for early gastric cancer. | Jesús Espinel Eugenia Pinedo Vanesa Ojeda Maria Guerra del Rio | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，12： | 11 |
| 3 | Chronic exposure to ethanol causes steatosis and inflammation in zebrafish liver显示文摘AIM To evaluate the effects of chronic exposure to ethanol in the liver and the expression of inflammatory genesin zebrafish.METHODS Zebrafish(n = 104),wild type,adult,male and female,were divided into two groups:Control and ethanol(0.05 v/v).The ethanol was directly added into water;tanks water were changed every two days and the ethanol replaced.The animals were fed twice a day with fish food until satiety.After two and four weeks of trial,livers were dissected,histological analysis(hematoxilineosin and Oil Red staining) and gene expression assessment of adiponectin,adiponectin receptor 2(adipor2),sirtuin-1(sirt-1),tumor necrosis factor-alpha(tnf-a),interleukin-1b(il-1b) and interleukin-10(il-10) were performed.Ultrastructural evaluations were conducted at fourth week.RESULTS Exposing zebrafish to 0.5% ethanol developed intense liver steatosis after four weeks,as demonstrated by oil red staining.In ethanol-treated animals,the main ultrastructural changes were related to cytoplasmic lipid particles and droplets,increased number of rough endoplasmic reticulum cisterns and glycogen particles.Between two and four weeks,hepatic mR NA expression of il-1b,sirt-1 and adipor2 were upregulated,indicating that ethanol triggered signaling molecules which are key elements in both hepatic inflammatory and protective responses.Adiponectin was not detected in the liver of animals exposed and not exposed to ethanol,and il-10 did not show significant difference.CONCLUSION Data suggest that inflammatory signaling and ultrastructural alterations play a significant role during hepatic steatosis in zebrafish chronically exposed to ethanol. | Ana Claudia Reis Schneider Cleandra Gregório Carolina Uribe-Cruz Ranieli Guizzo Tais Malysz Maria Cristina Faccioni-Heuser Larisse Longo Themis Reverbel da Silveira | 2017 | World Journal of Hepatology2017，9，8： | 7 |

| 5 | Iron homeostasis and H63D mutations in alcoholics with and without liver disease显示文摘AIM: To evaluate the prevalence of HFE gene mutation and indices of disturbed iron homeostasis in alcoholics with and without liver disease.METHODS: One hundred and fifty-three heavy drinkers (defined as alcohol consumption > 80 g/d for at least 5 years) were included in the study. These comprised 78 patients with liver disease [liver disease alcoholics (LDA)] in whom the presence of liver disease was confirmed by liver biopsy or clinical evidence of hepatic decompensation, and 75 subjects with no evidence of liver disease, determined by normal liver tests on two occasions [non-liver disease alcoholics (NLDA)], were consecutively enrolled. Serum markers of iron status and HFE C282Y and H63D mutations were determined. HFE genotyping was compared with data obtained in healthy blood donors from the same geographical area.RESULTS: Gender ratio was similar in both study groups. LDA patients were older than NLDA patients (52 ± 10 years vs 48 ± 11 years, P = 0.03). One third and one fi fth of the study population had serum transferrin saturation (TS) greater than 45% and 60% respectively. Serum iron levels were similar in both groups. However, LDA patients had higher TS (51 ± 27 vs 36 ± 13, P < 0.001) and ferritin levels (559 ± 607 ng/mL vs 159 ± 122 ng/mL, P < 0.001), and lower total iron binding capacity (TIBC) (241 ± 88 μg/dL vs 279 ± 40 μg/dL, P = 0.001). The odds ratio for having liver disease with TS greater than 45% was 2.20 (95% confi dence interval (CI): 1.37-3.54). There was no difference in C282Y allelic frequency between the two groups. However, H63D was more frequent in LDA patients (0.25 vs 0.16, P = 0.03). LDA patients had a greater probability of carrying at least one HFE mutation than NLDA patients (49.5% vs 31.6%, P = 0.02). The odds ratio for LDA in patients with H63D mutation was 1.57 (95% CI: 1.02-2.40).CONCLUSION: The present study confirms the presence of iron overload in alcoholics, which was more severe in the subset of subjects with liver disease, in parallel with an increased frequency of H63D HFE mutation. | Mariana Verdelho Machado Paula Ravasco Alexandra Martins Maria Rosário Almeida Maria Ermelinda Camilo Helena Cortez-Pinto | 2009 | World Journal of Gastroenterology2009，15，1： | 3 |
| 6 | Embryonal rhabdomyosarcoma in the maxillary sinus with orbital involvement in a pediatric patient:Case report显示文摘This report presents a case of embryonal rhabdomyosarcoma(e RMS) located in the left maxillary sinus and invading the orbital cavity in a ten-year-old male patient who was treated at a referral hospital.The images provided from the computed tomography showed a heterogeneous mass with soft-tissue density,occupying part of the left half of the face inside the maxillary sinus,and infiltrating and destroying the bone structure of the maxillary sinus,left orbit,ethmoidal cells,nasal cavity,and sphenoid sinus.An analysis of the histological sections revealed an undifferentiated malignant neoplasm infiltrating the skeletal muscle tissue.The immunohistochemical analysis was positive for the antigens:MyoD 1,myogenin,desmin,and Ki67(100% positivity in neoplastic cells),allowing the identification of the tumour as an eR MS.The treatment protocol included initial chemotherapy followed by radiotherapy and finally surgery.The total time of the treatment was nine months,and in 18-mo of follow-up period did not show no local recurrences and a lack of visual impairment. | Ana Carolina Rodrigues de Melo Tácio Candeia Lyra Isabella Lima Arrais Ribeiro Alexandre Rolim da Paz Paulo Rogério Ferreti Bonan Ricardo Dias de Castro Ana Maria Gondim Valen?a | 2017 | World Journal of Clinical Cases2017，5，12： | 3 |

| 8 | Assessing the relationship between the rumen microbiota and feed efficiency in Nellore steers显示文摘Background:Ruminants rely upon a complex community of microbes in their rumen to convert host-indigestible feed into nutrients.However,little is known about the association between the rumen microbiota and feed efficiency traits in Nellore(Bos indicus)cattle,a breed of major economic importance to the global beef market.Here,we compare the composition of the bacterial,archaeal and fungal communities in the rumen of Nellore steers with high and low feed efficiency(FE)phenotypes,as measured by residual feed intake(RFI).Results:The Firmicutes to Bacteroidetes ratio was significantly higher(P<0.05)in positive-RFI steers(p-RFI,low feed efficiency)than in negative-RFI(n-RFI,high feed efficiency)steers.The differences in bacterial composition from steers with high and low FE were mainly associated with members of the families Lachnospiraceae,Ruminococcaceae and Christensenellaceae,as well as the genus Prevotella.Archaeal community richness was lower(P<0.05)in p-RFI than in n-RFI steers and the genus Methanobrevibacter was either increased or exclusive of p-RFI steers.The fungal genus Buwchfawromyces was more abundant in the rumen solid fraction of n-RFI steers(P<0.05)and a highly abundant OTU belonging to the genus Piromyces was also increased in the rumen microbiota of highefficiency steers.However,analysis of rumen fermentation variables and functional predictions indicated similar metabolic outputs for the microbiota of distinct FE groups.Conclusions:Our results demonstrate that differences in the ruminal microbiota of high and low FE Nellore steers comprise specific taxa from the bacterial,archaeal and fungal communities.Biomarker OTUs belonging to the genus Piromyces were identified in animals showing high feed efficiency,whereas among archaea,Methanobrevibacter was associated with steers classified as p-RFI.The identification of specific RFI-associated microorganisms in Nellore steers could guide further studies targeting the isolation and functional characterization of rumen microbes potentially important for the energy-harvesting efficiency of ruminants. | Déborah Romaskevis Gomes Lopes Márcio de Souza Duarte Alex J.La Reau Ibrahim Zuniga Chaves Tiago Antônio de Oliveira Mendes Edenio Detmann Cláudia Braga Pereira Bento Maria Eugênia Zerlotti Mercadante Sarah Figueiredo Martins Bonilha Garret Suen Hilário Cuquetto Mantovani | 2021 | Journal of Animal Science and Biotechnology2021，12，4： | 3 |
| 9 | Association between EGF +61A/G polymorphism and gastric cancer in Caucasians显示文摘AIM: To investigate the association between epidermal growth factor (EGF) +61A/G polymorphism and susceptibility to gastric cancer, through a cross-sectional study. METHODS: Polymerase chain reaction resctriction fragment lenght polymorphism analyses were used to genotype EGF +61 in 207 patients with gastric lesions (162 patients with gastric adenocarcinomas, 45 with atrophy or intestinal metaplasia) and 984 controls. All subjects were Caucasian. RESULTS: Genotype distribution was 23.5% for GG and 76.5% for GA/AA in the control group, 18.4% for GG and 68.6% for GA/AA in the entire group with gastric lesions and 17.9% for GG and 82.1% for GA/AA in the group with gastric adenocarcinoma. No statistically significant associations were found between EGF +61 variants and risk for developing gastric cancer [odds ratios (OR) = 1.41, 95% confidence intervals (CI): 0.90-2.21, P = 0.116]. However, the stratification of individuals by gender revealed that males carrying A alleles (EGF +61A/G or AA) had an increased risk for developing gastric cancer as compared to GG homozygous males (OR = 1.55, 95% CI: 1.05-2.28, P = 0.021). CONCLUSION: In summary, we found that males who were A carriers for EGF +61 had an increased risk for developing gastric cancer. This result may be explained by the suggestion that women secrete less gastric acid than men. | Ana Paula Araújo Bruno M Costa Ana L Pinto-Correia Maria Fragoso Paula Ferreira Mário Dinis-Ribeiro Sandra Costa Rui M Reis Rui Medeiros | 2011 | World Journal of Gastroenterology2011，17，4： | 3 |
| 10 | Epidemiology of upper gastrointestinal symptoms in Brazil(Epi Gastro):A population-based study according to sex and age group显示文摘AIM:To determine the prevalences of symptoms consistent with gastroesophageal reflux disease(GERD)and dyspepsia in South America.METHODS:A telephone survey was conducted among adult owners of land-based telephones in S?o Paulo,Brazil,using previously validated computer-assisted sampling and survey protocols.The Portugueselanguage survey included(1)sociodemographic characteristics(e.g.,weight,height,smoking)and comorbidities;(2)dietary habits;(3)presence of symptoms consistent with GERD or dyspepsia within the prior 3mo;and(4)use of medications and other therapies to manage symptoms.Data were stratified post-hoc into three homogeneous geographical regions of S?o Paulo according to the Social Exclusion Indices of the districts and postal codes.Survey response data from each respondent were weighted by the numbers of adults and landline telephones in each household.The analyses were weighted to account for sampling design and to be representative of the S?o Paulo population according to city census data.RESULTS:Among 4570 households contacted,an adult from 3050(66.7%)agreed to participate.The nonresponse rate was 33.3%.The mean(SE)respondent age was 42.6(16.0)years.More than half of all respondents were women(53.1%),aged 18 through 49 years(66.7%),married or cohabitating(52.5%),and/or above normal-weight standards(i.e.,35.3%overweight and 16.3%obese).A total of 26.5%of women were perimenopausal.More than 20%of respondents reported highly frequent symptoms consistent with GERD(e.g.,gastric burning sensation=20.8%)or dyspepsia(e.g.,abdominal swelling/distension=20.9%)at least once per month.Prevalences of these symptoms were significantly(approximately 1.5-to 2.0-fold)higher among women than men but did not vary significantly as a function of advancing age.For instance,14.1%of women reported that they experienced stomach burning(symptom of GERD)at least twice per week,compared to 8.4%of men(P=0.012 byχ2 test).A total of 15.7%of women reported that they experienced abdominal swelling(symptom of dyspepsia)at least twice per week,compared to 6.4%of men(P<0.001byχ2 test).Despite frequent manifestations of GERD or dyspepsia,most(≥90%)respondents reported that they neither received prescription medications fromphysicians,nor took behavioral measures(e.g.,dietary modifications),to manage symptoms.CONCLUSION:Symptoms consistent with dyspepsia and GERD are prevalent in Brazil and represent major public-health and clinical challenges. | Maria do Rosário Dias de Oliveira Latorre Aline Medeiros da Silva Décio Chinzon Jaime N Eisig Telma RP Dias-Bastos | 2014 | World Journal of Gastroenterology2014，20，46： | 2 |
| 11 | How to manage inflammatory bowel disease during the COVID-19 pandemic:A guide for the practicing clinician显示文摘Managing inflammatory bowel disease(IBD)during the coronavirus disease 2019(COVID-19)pandemic has been a challenge faced by clinicians and their patients,especially concerning whether to proceed with biologics and immunosuppressive agents in the background of a global outbreak of a highly contagious new coronavirus(severe acute respiratory syndrome coronavirus 2,SARS-CoV-2).The knowledge about the impact of this virus on patients with IBD,although it is still scarce,is rapidly evolving.In particular,concerns surrounding medications’impact for IBD on the risk of acquiring SARS-CoV-2 infection or developing COVID-19,and potentially exacerbate viral replication and the COVID-19 course,are a current thinking of both practicing clinicians and providers caring for patients with IBD.Managing patients with IBD infected with SARS-CoV-2 depends on both the clinical activity of the IBD and the occasional development and severity of COVID-19.In this review,we summarize the current data regarding gastrointestinal involvement by SARS-CoV-2 and pharmacologic and surgical management for IBD concerning this infection,and the COVID-19 impact on both the patient's psychological functioning and endoscopy services,and we concisely summarize the telemedicine roles during the COVID-19 pandemic. | Júlio Maria Fonseca Chebli Natália Sousa Freitas Queiroz Adérson Omar Mourão Cintra Damião Liliana Andrade Chebli Márcia Henriques de Magalhães Costa Rogério Serafim Parra | 2021 | World Journal of Gastroenterology2021，27，11： | 2 |

| 13 | Assessing the estrogenic potency in a Portuguese wastewater treatment plant using an integrated approach显示文摘The estrogenic potency of a wastewater treatment plant(WWTP) was evaluated using chemical and biological analyses,which showed that after the station treatment processes some of the selected endocrine disruptor compounds(EDCs) were still present in the treated effuent(e.g.,bisphenol A,alkylphenols,estrone) .Thus,the most common endocrine EDCs were identified and quantified and the overall estrogenicity of the treated effuent assessed by integrating the results.Male goldfish(Carassius auratus) were used as biological indicators in a 28-day experiment.Vitellogenin(Vtg) ,gonadosomatic and hepatosomatic indices,steroids(17β-estradiol and 11-ketotestosterone) and histopathology were biomarkers used in fish to evaluate WWTP treated effuent estrogenicity,in combination with instrumental analyses.The results showed a significant increase(P<0.01) in plasma and liver Vtg,which were significantly correlated(r=0.66;P<0.01) .The gonadosmatic index was significantly(P<0.01) reduced in exposed fish.The steroid analyses revealed significant elevations in 17β-estradiol and depressed 11-ketotestosterone concentrations.The histological examinations show changes in exposed fish gonads,such as regressed testes and in some cases(43%to 75%) the development of ovo-testis in fish exposed to 50% and 100% treated effuent. | Mário S.Diniz Rita Maurício Mira Petrovic Maria J.López De Alda Leonor Amaral Isabel Peres Damiá Barceló Fernando Santana | 2010 | Journal of Environmental Sciences2010，22，10： | 2 |
