| 1 | Renin angiotensin system in liver diseases: Friend or foe?显示文摘In the last three decades,the understanding of the renin angiotensin system(RAS)has been changed by the discoveries of functional local systems,novel biologically active peptides,additional specific receptors,alternative pathways of angiotensin(Ang)?Ⅱ?generation,and new roles for enzymes and precursor components other than those in Ang?Ⅱ?synthesis.In this regard,the discovery that Ang-(1-7)opposes the pressor,proliferative,pro-fibrotic,and pro-inflammatory effects mediated by Ang?Ⅱ?has contributed to the realization that the RAS is composed of two axes.The first axis consists of the angiotensin-converting enzyme(ACE),with Ang?Ⅱ?as the end product,and the angiotensin type 1(AT1)receptor as the main effector mediating the biological actions of Ang?Ⅱ.The second axis results from ACE2-mediated hydrolysis of Ang?Ⅱ,leading to the production of Ang-(1-7),with the Mas receptor as the main effector conveying the vasodilatory,antiproliferative,anti-fibrotic,and anti-inflammatory effects of Ang-(1-7).Experimental and clinical studies have shown that both axes of the RAS may take part in the pathogenesis of liver diseases.In this manuscript,we summarize the current evidence regarding the role of RAS in hepatic cirrhosis and its complications,including hemodynamic changes and hepatorenal syndrome.The therapeutic potential of the modulation of RAS molecules in liver diseases is also discussed. | Ana Cristina Simoes e Silva Aline S Miranda Natália P Rocha Antonio L Teixeira | 2017 | World Journal of Gastroenterology2017，23，19： | 12 |
| 2 | Subclinical carotid atherosclerosis predicts all-cause mortality and cardiovascular events in obese patients with negative exercise echocardiography显示文摘BACKGROUND Obesity is a major health problem due to its high prevalence. The relationship between obesity and cardiovascular disease is unclear. Some studies agree that certain conditions associated with obesity, such as physical inactivity or cardiovascular risk factors, are responsible for cardiovascular risk excess among obese people. Carotid intima-media thickness and carotid plaques(CP) have been associated with cardiovascular adverse events in healthy populations, and recent data suggest a higher prevalence of subclinical carotid atherosclerosis in obese and metabolically unhealthy patients. However, there are no studies correlating subclinical atherosclerosis and adverse events(AE) in obese subjects.AIM To determine the association between carotid disease and AE in obese patients with negative exercise echocardiography(EE).METHODS From January 1, 2006 to December 31, 2010, 2000 consecutive patients with a suspicion of coronary artery disease were submitted for EE and carotid ultrasonography. Exclusion criteria included previous vascular disease, left ventricular ejection fraction < 50%, positive EE, significant valvular heart disease and inferior to submaximal EE. An AE was defined as all-cause mortality,myocardial infarction and cerebrovascular accident. Subclinical atherosclerosis was defined as CP presence according to Manheim and the American Society of Echocardiography Consensus.RESULTS Of the 652 patients who fulfilled the inclusion criteria, 226(34.7%) had body mass indexes ≥ 30 kg/m2, and 76 of them(33.6%) had CP. During a mean follow-up time of 8.2(2.1) years, 27 AE were found(11.9%). Mean event-free survival at 1, 5 and 10 years was 99.1%(0.6), 95.1%(1.4) and 86.5%(2.7), respectively. In univariate analysis, CP predicted AE [hazard ratio(HR) 2.52, 95% confidence interval(CI) 1.17-5.46; P = 0.019]. In multivariable analysis, the presence of CP remained a predictor of AE(HR 2.26, 95%CI 1.04-4.95, P = 0.041). Other predictors identified were glomerular filtration rate(HR 0.98, 95%CI 0.96-0.99; P= 0.023), peak metabolic equivalents(HR 0.83, 95%CI 0.70–0.99, P = 0.034) and moderate mitral regurgitation(HR 5.02, 95%CI 1.42–17.75, P = 0.012).CONCLUSION Subclinical atherosclerosis defined by CP predicts AE in obese patients with negative EE. These patients could benefit from aggressive prevention measures. | Rafael Vidal-Perez Raúl Franco-Gutiérrez Alberto J Pérez-Pérez Virginia Franco-Gutiérrez Alberto Gascón-Vázquez Andrea López-López Ana María Testa-Fernández Carlos González-Juanatey | 2019 | World Journal of Cardiology2019，11，1： | 7 |
| 3 | Metabolic syndrome and colorectal neoplasms:An ominous association显示文摘AIM:To evaluate the association of metabolic syndrome(MS) and colorectal cancer and adenomas in a Western country,where the incidence of MS is over 27%.METHODS:This was a prospective study between March 2013 and March 2014.MS was diagnosed according to the National Cholesterol Education ProgramATP III.Demographic characteristics,anthropometric measurements,metabolic risk factors,and colonoscopic pathologic findings were assessed in patients with MS(group 1) who underwent routine colonoscopy at our department.This data was compared with consecutive patients without metabolic syndrome(group 2),with no differences regarding sex and age.Patients with incomplete colonoscopy,family history,or past history of colorectal neoplasm were excluded.Informed consent was obtained and the ethics committee approved this study.Statistical analysis was performed using Student's t-test and χ2 test,with a P value ≤ 0.05 being considered statistically significant.RESULTS:Of 258 patients,129 had MS;51% males;mean-age 67.1 years(50-87).Among the MS group,94% had high blood pressure,91% had increased waist circumference,60% had diabetes,55% had low high-density lipoprotein cholesterol level,50% had increased triglyceride level,and 54% were obese [body mass index(BMI) 30 kg/m2].51% presented 4 criteria of MS.MS was associated with increased prevalence of adenomas(43% vs 25%,P = 0.004) and colorectal cancer(13% vs 5%,P = 0.027),compared with patients without MS.MS was also positively associated with multiple(≥ 3) adenomas(35% vs 9%,P = 0.024) and sessile adenomas(69% vs 53%,P = 0.05).No difference existed between location(P = 0.086),grade of dysplasia(P = 0.196),or size(P= 0.841) of adenomas.In addition,no difference was found between BMI(P = 0.078),smoking(P = 0.146),alcohol consumption(P = 0.231),and the presence of adenomas.CONCLUSION:MS is positively associated with adenomas and colorectal cancer.However,there is not enough information in western European countries to justify screening in patients with MS.To our knowledge,no previous study has evaluated this association in Portuguese patients. | Daniel Trabulo Suzane Ribeiro Cláudio Martins Cristina Teixeira Cláudia Cardoso Jo?o Mangualde Ricardo Freire élia Gamito Ana L Alves Fátima Augusto Ana P Oliveira Isabelle Cremers | 2015 | World Journal of Gastroenterology2015，21，17： | 5 |
| 4 | Sex-specific effects of Eugenia punicifolia extract on gastric ulcer healing in rats显示文摘AIM To evaluate the sex-specific effects of a hydroalcoholic extract from Eugenia punicifolia(HEEP) leaves on gastric ulcer healing.METHODS In this rat study involving males, intact(cycling) females, and ovariectomized females, gastric ulcers were induced using acetic acid. A vehicle, lansoprazole, or HEEP was administered for 14 d after ulcer induction. Body weight was monitored throughout the treatment period. At the end of treatment, the rats were euthanized and the following in vivo and in vitro investigations were performed: macroscopic examination of the lesion area and organ weights, biochemical analysis, zymography, and evaluation of protein expression levels. Additionally, the concentration-dependent effect of HEEP was evaluated in terms of subacute toxicity and cytotoxicity.RESULTS Compared to the vehicle, HEEP demonstrated a great healing capacity by substantially reducing the ulcerative lesion area in males(52.44%), intact females(85.22%), and ovariectomized females(65.47%), confirming that HEEP accelerates the healing of acetic acidinduced gastric lesions and suggesting that this effect is modulated by female sex hormones. The antiulcer effect of HEEP was mediated by prostaglandin E2 only in male rats. Overall, the beneficial effect of HEEP was the highest in intact females. Notably, HEEP promoted the expression of vascular endothelial growth factor(intact vs ovariectomized females) and decreased the expression of Caspase-8 and Bcl-2(intact female vs male or ovariectomized female). Additionally, HEEP enhanced fibroblast proliferation and migration into a wounded area in vitro, confirming its healing effect. Finally, no sign of subacute toxicity or cytotoxicity of HEEP was observed.CONCLUSION In gastric ulcers, HEEP-induced healing(modulated by female sex hormones; in males, mediated by prostaglandin) involves extracellular matrix remodeling, with gastric mucosa cell proliferation and migration. | Larissa Lucena Périco Vinícius Peixoto Rodrigues Rie Ohara Gabriela Bueno Vania Vasti Alfieri Nunes Raquel Cássia dos Santos Ana Carolina Lima Camargo Luis Antuio Justulin Joior Sérgio Faloni de Andrade Viviane Miranda Bispo Steimbach Luísa Mota da Silva Lúcia Regina Machado da Rocha Wagner Vilegas Catarina dos Santos Clélia Akiko Hiruma-Lima | 2018 | World Journal of Gastroenterology2018，24，38： | 3 |
| 5 | Appropriateness of outpatient gastrointestinal endoscopy in a non-academic hospital显示文摘AIM:To assess the appropriate use and the diagnostic yield of upper gastrointestinal endoscopy and colonoscopy in this subgroup of patients.METHODS:In total,789 consecutive outpatients referred for gastrointestinal(GI) endoscopy [381 for esophagogastroduodenoscopy(EGD) and 408 for colonoscopy] were prospectively enrolled in the study.The American Society for Gastrointestinal Endoscopy(ASGE) guidelines were used to assess the relationship between appropriateness and the presence of relevant endoscopic f indings.RESULTS:The overall inappropriate rate was 13.3%.The indications for EGD and colonoscopy were,respectively,appropriate in 82.7% and 82.6% of the exams,uncertain in 5.8% and 2.4% and inappropriate in 11.5% and 15%.The diagnostic yield was signif icant higher forEGDs and colonoscopies judged appropriate and uncertain when compared with those considered inappropriate(EGD:36.6% vs 36.4% vs 11.4%,P = 0.004;Colonoscopy:24.3% vs 20.0% vs 3.3%,P = 0.001).Of the 25 malignant lesions detected,all but one was detected in exams judged appropriate or uncertain.CONCLUSION:This study shows a good adherence to ASGE guidelines by the referring physicians and a significant increase of the diagnostic yield in appropriate examinations,namely in detecting neoplastic lesions.It underscores the importance that the appropriateness of the indication assumes in assuring high-quality GI endoscopic procedures. | Joo Mangualde Marie I Cremers Ana M Vieira Ricardo Freire lia Gamito Cristina Lobato Ana L Alves Fátima Augusto Ana P Oliveira | 2011 | World Journal of Gastrointestinal Endoscopy2011，3，10： | 2 |
| 6 | Dendritic cell deficiencies persist seven months after SARS-CoV-2 infection显示文摘Severe Acute Respiratory Syndrome Coronavirus(SARS-CoV)-2 infection induces an exacerbated inflammation driven by innate immunity components.Dendritic cells(DCs)play a key role in the defense against viral infections,for instance plasmacytoid DCs(pDCs),have the capacity to produce vast amounts of interferon-alpha(IFN-α).In COVID-19 there is a deficit in DC numbers and IFN-αproduction,which has been associated with disease severity.In this work,we described that in addition to the DC deficiency,several DC activation and homing markers were altered in acute COVID-19 patients,which were associated with multiple inflammatory markers.Remarkably,previously hospitalized and nonhospitalized patients remained with decreased numbers of CD1c+myeloid DCs and pDCs seven months after SARS-CoV-2 infection.Moreover,the expression of DC markers such as CD86 and CD4 were only restored in previously nonhospitalized patients,while no restoration of integrinβ7 and indoleamine 2,3-dyoxigenase(IDO)levels were observed.These findings contribute to a better understanding of the immunological sequelae of COVID-19. | Alberto Pérez-Gómez Joana Vitallé Carmen Gasca-Capote Alicia Gutierrez-Valencia María Trujillo-Rodriguez Ana Serna-Gallego Esperanza Muñoz-Muela María de los Reyes Jiménez-Leon Mohamed Rafii-El-Idrissi Benhnia Inmaculada Rivas-Jeremias Cesar Sotomayor Cristina Roca-Oporto Nuria Espinosa Carmen Infante-Domínguez Juan Carlos Crespo-Rivas Alberto Fernández-Villar Alexandre Pérez-González Luis Fernando López-Cortés Eva Poveda Ezequiel Ruiz-Mateos JoséMiguel Cisneros Sonsoles Salto-Alejandre Judith Berastegui-Cabrera Pedro Camacho-Martínez Carmen Infante-Domínguez Marta Carretero-Ledesma Juan Carlos Crespo-Rivas Eduardo Márquez JoséManuel Lomas Claudio Bueno Rosario Amaya JoséAntonio Lepe Jerónimo Pachón Elisa Cordero Javier Sánchez-Céspedes Manuela Aguilar-Guisado Almudena Aguilera Clara Aguilera Teresa Aldabo-Pallas Verónica Alfaro-Lara Cristina Amodeo Javier Ampuero María Dolores Avilés Maribel Asensio Bosco Barón-Franco Lydia Barrera-Pulido Rafael Bellido-Alba Máximo Bernabeu-Wittel Candela Caballero-Eraso Macarena Cabrera Enrique Calderón Jesús Carbajal-Guerrero Manuela Cid-Cumplido Yael Corcia-Palomo Juan Delgado Antonio Domínguez-Petit Alejandro Deniz Reginal Dusseck-Brutus Ana Escoresca-Ortega Fátima Espinosa Nuria Espinosa Michelle Espinoza Carmen Ferrándiz-Millón Marta Ferrer Teresa Ferrer Ignacio Gallego-Texeira Rosa Gámez-Mancera Emilio García Horacio García-Delgado Manuel García-Gutiérrez María Luisa Gascón-Castillo Aurora González-Estrada Demetrio González Carmen Gómez-González Rocío González-León Carmen Grande-Cabrerizo Sonia Gutiérrez Carlos Hernández-Quiles Inmaculada Concepción Herrera-Melero Marta Herrero-Romero Luis Jara Carlos Jiménez-Juan Silvia Jiménez-Jorge Mercedes Jiménez-Sánchez Julia Lanseros-Tenllado Carmina López Isabel López Álvaro López-Barrios Luis F.López-Cortés Rafael Luque-Márquez Daniel Macías-García Guillermo Martín-Gutiérrez Luis Martín-Villén JoséMolina Aurora Morillo María Dolores Navarro-Amuedo Dolores Nieto-Martín Francisco Ortega María Paniagua-García Amelia Peña-Rodríguez Esther Pérez Manuel Poyato Julia Praena-Segovia Rafaela Ríos Cristina Roca-Oporto Jesús F.Rodríguez María Jesús Rodríguez-Hernández Santiago Rodríguez-Suárez Ángel Rodríguez-Villodres Nieves Romero-Rodríguez Ricardo Ruiz Zida Ruiz de Azua Celia Salamanca Sonia Sánchez Víctor Manuel Sánchez-Montagut César Sotomayor Alejandro Suárez Benjumea Javier Toral | 2021 | Cellular & Molecular Immunology2021，18，9： | 2 |
