| 1 | Helicobacter pylori and EBV in gastric carcinomas:Methylation status and microsatellite instability显示文摘AIM:To verify the methylation status of CDH1, DAPK, COX2, hMLH1 and CDKN2A genes and to evaluate their association with Helicobacter pylori (H. pylori)-cagA+ and Epstein Barr virus (EBV) infections in gastric adenocarcinomas.METHODS: Methylation-specific PCR (MSP) assay was performed in 89 primary gastric carcinomas (intestinal and diffuse types). Microsatellite instability (MSI) analysis was performed using the BAT26 primer set and PCR products were analyzed with the ABI PRISM 3100 Genetic Analyzer using Genescan 3.7 software (Applied Biosystems). Detection of H. pylori and genotyping were performed by PCR, using specifi c primers for ureaseC and cagA genes. The presence of EBV was assessed by in situ hybridization. Statistical analyses were performed using the χ2 or Fisher's exact test.RESULTS: The most frequent hypermethylated gene was COX-2 (63.5%) followed by DAPK (55.7%), CDH1 (51%), CDKN2A (36%) and hMLH1 (30.3%). Intestinal and diffuse adenocarcinomas showed different methylation profiles and there was an association between methylation of E-CDH1 and H. pylori-cagA+ in the intestinal adenocarcinoma type. MSI was correlated with hMLH1 methylation. There was an inverse correlation between DAPK hypermethylation and MSI.CONCLUSION: We found a strong association between CDH1 methylation and H. pylori-cagA+ in intestinal-type gastric cancer, association of MSI and better prognosis and an heterogeneous COX-2 overexpression. | Adriana Camargo Ferrasi Nídia Alice Pinheiro Silvia Helena Barem Rabenhorst Otávia Luisa Caballero Maria Aparecida Marchesan Rodrigues Fabrício de Carvalho Celso Vieira de Souza Leite Marcia Valéria Pitombeira Ferreira Marcos Aurélio Pessoa Barros Maria Inês de Moura Campos Pardini | 2010 | World Journal of Gastroenterology2010，16，3： | 6 |
| 2 | Fecal immunochemical test accuracy in average-risk colorectal cancer screening显示文摘AIM:To assess the fecal immunochemical test(FIT)accuracy for colorectal cancer(CRC)and advanced neoplasia(AN)detection in CRC screening.METHODS:We performed a multicentric,prospective,double blind study of diagnostic tests on asymptomatic average-risk individuals submitted to screening colonoscopy.Two stool samples were collected and the fecal hemoglobin concentration was determined in the first sample(FIT1)and the highest level of both samples(FITmax)using the OC-sensor.Areas under the curve(AUC)for CRC and AN were calculated.The best FIT1and FITmax cut-off values for CRC were determined.At this threshold,number needed to scope(NNS)to detect a CRC and an AN and the cost per lesion detected were calculated.RESULTS:About 779 individuals were included.An AN was found in 97(12.5%)individuals:a CRC in 5(0.6%)and an advanced adenoma(≥10 mm,villous histology or high grade dysplasia)in 92(11.9%)subjects.For CRC diagnosis,FIT1 AUC was 0.96(95%CI:0.95-0.98)and FITmax AUC was 0.95(95%CI:0.93-0.97).For AN,FIT1 and FITmax AUC were similar(0.72,95%CI:0.66-0.78 vs 0.73,95%CI:0.68-0.79,respectively,P=0.34).Depending on the number of determinations and the positivity threshold cut-off used sensitivity for AN detection ranged between 28%and 42%and specificity between 91%and 97%.At the best cut-off point for CRC detection(115 ng/mL),the NNS to detect a CRC were 10.2 and 15.8;and the cost per CRC was 1814€and 2985€on FIT1 and FITmax strategies respectively.At this threshold the sensitivity,NNS and cost per AN detected were 30%,1.76,and 306€,in FIT1 strategy,and 36%,2.26€and 426€,in FITmax strategy,respectively.CONCLUSION:Performing two tests does not improve diagnostic accuracy,but increases cost and NNS to detect a lesion. | Vicent Hernandez Joaquin Cubiella M Carmen Gonzalez-Mao Felipe Iglesias Concepción Rivera M Begoa Iglesias Lucía Cid Ines Castro Luisa de Castro Pablo Vega Jose Antonio Hermo Ramiro Macenlle Alfonso Martínez-Turnes David Martínez-Ares Pamela Estevez Estela Cid M Carmen Vidal Angeles López-Martínez Elisabeth Hijona Marta Herreros-Villanueva Luis Bujanda Jose Ignacio Rodriguez-Prada the COLONPREV study investigators | 2014 | World Journal of Gastroenterology2014，20，4： | 4 |
| 3 | Nutritional therapy for hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC)is the most frequent primary liver cancer and presents together with cirrhosis in most cases.In addition to commonly recognized risk factors for HCC development,such as hepatitis B virus/hepatitis C virus infection,age and alcohol/tobacco consumption,there are nutritional risk factors also related to HCC development including high intake of saturated fats derived from red meat,type of cooking(generation of heterocyclic amines)and contamination of foods with aflatoxins.On the contrary,protective nutritional factors include diets rich in fiber,fruits and vegetables,n-3 polyunsaturated fatty acids and coffee.While the patient is being evaluated for staging and treatment of HCC,special attention should be paid to nutritional support,including proper nutritional assessment and therapy by a multidisciplinary team.It must be considered that these patients usually develop HCC on top of long-lasting cirrhosis,and therefore they could present with severe malnutrition.Cirrhosisrelated complications should be properly addressed and considered for nutritional care.In addition to traditional methods,functional testing,phase angle and computed tomography scan derived skeletal muscle index-L3 are among the most useful tools for nutritional assessment.Nutritional therapy should be centered on providing enough energy and protein to manage the increased requirements of both cirrhosis and cancer.Supplementation with branched-chain amino acids is also recommended as it improves response to treatment,nutritional status and survival,and finally physical exercise must be encouraged and adapted to individual needs. | Astrid Ruiz-Margáin Berenice M Román-Calleja Paulina Moreno-Guillén JoséA González-Regueiro DeyaniraKúsulas-Delint Alejandro Campos-Murguía Nayelli C Flores-García Ricardo Ulises Macías-Rodríguez | 2021 | World Journal of Gastrointestinal Oncology2021，13，10： | 4 |
| 4 | Immunohistochemical expression of intrarenal renin angiotensin system components in response to tempol in rats fed a high salt diet显示文摘AIM To determine the effect of tempol in normal rats fed high salt on arterial pressure and the balance between antagonist components of the renal renin-angiotensin system.METHODS Sprague-Dawley rats were fed with 8% Na Cl highsalt(HS) or 0.4% Na Cl(normal-salt,NS) diet for 3 wk,with or without tempol(T)(1 mmol/L,administered in drinking water). Mean arterial pressure(MAP),glomerularfiltration rate(GFR),and urinary sodium excretion(UVNa) were measured. We evaluated angiotensin Ⅱ(Ang Ⅱ),angiotensin 1-7(Ang 1-7),angiotensin converting enzyme 2(ACE2),mas receptor(Mas R),angiotensin type 1 receptor(AT1R) and angiotensin type 2 receptor(AT2R) in renal tissues by immunohistochemistry.RESULTS The intake of high sodium produced a slight but significant increase in MAP and differentially regulated components of the renal renin-angiotensin system(RAS). This included an increase in Ang Ⅱ and AT1 R,and decrease in ACE-2 staining intensity using immunohistochemistry. Antioxidant supplementation with tempol increased natriuresis and GFR,prevented changes in blood pressure and reversed the imbalance of renal RAS components. This includes a decrease in Ang Ⅱ and AT1 R,as increase in AT2,ACE2,Ang(1-7) and Mas R staining intensity using immunohistochemistry. In addition,the natriuretic effects of tempol were observed in NS-T group,which showed an increased staining intensity of AT2,ACE2,Ang(1-7) and Mas R.CONCLUSION These findings suggest that a high salt diet leads to changes in the homeostasis and balance between opposing components of the renal RAS in hypertension to favour an increase in Ang Ⅱ. Chronic antioxidant supplementation can modulate the balance between the natriuretic and antinatriuretic components of the renal RAS. | Gabriel Cao Silvana Lorena Della Penna Nicolas Martín Kouyoumdzian Marcelo Roberto Choi Susana Gorzalczany Belisario Enrique Fernández Jorge Eduardo Toblli María Inés Roson | 2017 | World Journal of Nephrology2017，6，1： | 4 |

| 6 | Beta-blocker therapy in elderly patients with renal dysfunction and heart failure显示文摘OBJECTIVE To assess the role of beta-blockers(BB)in patients with chronic kidney disease(CKD)aged≥75 years.METHODS AND RESULTS From January 2008 to July 2014,we included 390 consecutive patients≥75 years of age with ejection fraction≤35%and glomerular filtration rate(GFR)≤60 m L/min per 1.73 m^2.We analyzed the relationship between treatment with BB and mortality or cardiovascular events.The mean age of our population was 82.6±4.1 years.Mean ejection fraction was 27.9%±6.5%.GFR was 60-45 m L/min per 1.73 m^2 in 50.3%of patients,45-30 m L/min per 1.73 m^2 in 37.4%,and<30 m L/min per 1.73 m^2 in 12.3%.At the conclusion of follow-up,67.4%of patients were receiving BB.The median follow-up was28.04(IR:19.41-36.67)months.During the study period,211 patients(54.1%)died and 257(65.9%)had a major cardiovascular event(death or hospitalization for heart failure).BB use was significantly associated with a reduced risk of death(HR=0.51,95%CI:0.35-0.74;P<0.001).Patients receiving BB consistently showed a reduced risk of death across the different stages of CKD:stage IIIa(GFR=30-45 m L/min per 1.73 m^2;HR=0.47,95%CI:0.26-0.86,P<0.0001),stage IIIb(GFR 30-45 m L/min per 1.73 m^2;HR=0.55,95%CI:0.26-1.06,P=0.007),and stages IV and V(GFR<30 m L/min per 1.73 m~2;HR=0.29,95%CI:0.11-0.76;P=0.047).CONCLUSIONS The use of BB in elderly patients with HFr EF and renal impairment was associated with a better prognosis.Use of BB should be encouraged when possible. | Juan Martínez-Milla Marcelino Cortés García Julia Anna Palfy Mikel Taibo Urquía Marta López Castillo Ana Devesa Arbiol Ana Lucía Rivero Monteagudo María Luisa Martín Mariscal Inés Jiménez-Varas Sem Briongos Figuero Juan Antonio Franco-Pelaéz JoséTuñón | 2021 | Journal of Geriatric Cardiology2021，18，1： | 3 |
| 7 | Preclinical evaluation of azathioprine plus buthionine sulfoximine in the treatment of human hepatocarcinoma and colon carcinoma显示文摘AIM: To evaluate the efficacy and the safety of azathioprine (AZA) and buthionine sulfoximine (BSO) bylocalized application into HepG2 tumor in vivo.METHODS: Different hepatoma and colon carcinoma cell lines (HepG2, HuH7, Chang liver, LoVo, RKO, SW-48, SW-480) were grown in minimal essencial medium supplemented with 10% fetal bovine serum and 1% antibiotic/antimycotic solution and maintained in a humidified 37 ℃ incubator with 5% CO2. These cells were pretreated with BSO for 24 h and then with AZA for different times. We examined the effects of this combination on some proteins and on cellular death. We also studied the eff icacy and the safety of AZA (6 mg/kg per day) and BSO (90 mg/kg per day) in HepG2 tumor growth in vivo using athymic mice. We measured safety by serological markers such as aminotransferases and creatine kinase.RESULTS: The in vitro studies revealed a new mechanism of action for the AZA plus BSO combination in the cancer cells compared with other thiopurines (6-mercaptopurine, 6-methylmercaptopurine, 6-thioguanine and 6-methylthioguanine) in combination with BSO. The cytotoxic effect of AZA plus BSO in HepG2 cells resulted from necroptosis induction in a mitochondrial-dependent manner. From kinetic studies we suggest that glutathione (GSH) depletion stimulates c-Jun amino-terminal kinase and Bax translocation in HepG2 cells with subsequent deregulation of mitochondria (cytochrome c release, loss of membrane potential), and proteolysis activation leading to loss of membrane integrity, release of lactate dehydrogenase and DNA degradation. Some of this biochemical and cellular changes could be reversed by N-acetylcysteine (a GSH replenisher). In vivo studies showed that HepG2 tumor growth was inhibited when AZA was combined with BSO.CONCLUSION: Our studies suggest that a combination of AZA plus BSO could be useful for localizedtreatment of hepatocellular carcinoma as in the currently used transarterial chemoembolization method. | Borja Hernández-Breijo Jorge Monserrat Sara Ramírez-Rubio Eva P Cuevas Diana Vara Inés Díaz-Laviada M Dolores Fernández-Moreno Irene D Román Javier P Gisbert Luis G Guijarro | 2011 | World Journal of Gastroenterology2011，17，34： | 2 |

| 11 | Renal dopaminergic system:Pathophysiological implications and clinical perspectives显示文摘Fluid homeostasis, blood pressure and redox balance in the kidney are regulated by an intricate interaction between local and systemic anti-natriuretic and natriuretic systems. Intrarenal dopamine plays a central role on this interactive network. By activating specific receptors, dopamine promotes sodium excretion and stimulates anti-oxidant and anti-inflammatory pathways. Different pathological scenarios where renal sodium excretion is dysregulated, as in nephrotic syndrome, hypertension and renal inflammation, can be associated with impaired action of renal dopamine including alteration in biosynthesis, dopamine receptor expression and signal transduction. Given its properties on the regulation of renal blood flow and sodium excretion, exogenous dopamine has been postulated as a potential therapeutic strategy to prevent renal failure in critically ill patients. The aim of this review is to update and discuss on the most recent findings about renal dopaminergic system and its role in several diseases involving the kidneys and the potential use of dopamine as a nephroprotective agent. | Marcelo Roberto Choi Nicolás Martín Kouyoumdzian Natalia Lucía Rukavina Mikusic María Cecilia Kravetz María Inés Rosón Martín Rodríguez Fermepin Belisario Enrique Fernández | 2015 | World Journal of Nephrology2015，4，2： | 2 |
