| 1 | Computed tomography-guided percutaneous core needle biopsy in pancreatic tumor diagnosis显示文摘AIM: To evaluate the techniques, results, and complications related to computed tomography(CT)-guided percutaneous core needle biopsies of solid pancreatic lesions.METHODS: CT-guided percutaneous biopsies of solid pancreatic lesions performed at a cancer reference center between January 2012 and September 2013 were retrospectively analyzed. Biopsy material was collected with a 16-20 G Tru-Core needle(10-15 cm; Angiotech, Vancouver, CA) using a coaxial system and automatic biopsy gun. When direct access to the lesion was not possible, indirect(transgastric or transhepatic) access or hydrodissection and/or pneumodissection maneuvers were used. Characteristics of the patients, lesions, procedures, and histologic results were recorded using a standardized form. RESULTS: A total of 103 procedures included in the study were performed on patients with a mean age of 64.8 year(range: 39-94 year). The mean size of the pancreatic lesions was 45.5 mm(range: 15-195 mm). Most(75/103, 72.8%) procedures were performed via direct access, though hydrodissection and/or pneumodissection were used in 22.2%(23/103) of cases and indirect transhepatic or transgastric access was used in 4.8%(5/103) of cases. Histologic analysis was performed on all biopsies, and diagnoses were conclusive in 98.1%(101/103) of cases, confirming3.9%(4/103) of tumors were benign and 94.2%(97/103) were malignant; results were atypical in 1.9%(2/103) of cases, requiring a repeat biopsy to diagnose a neuroendocrine tumor, and surgical resection to confirm a primary adenocarcinoma. Only mild/moderate complications were observed in 9/103 patients(8.7%),and they were more commonly associated with biopsies of lesions located in the head/uncinate process(n =8), than of those located in the body/tail(n = 1) of the pancreas, but this difference was not significant.CONCLUSION: CT-guided biopsy of a pancreatic lesion is a safe procedure with a high success rate, and is an excellent option for minimally invasive diagnosis. | Chiang J Tyng Maria Fernanda A Almeida Paula NV Barbosa Almir GV Bitencourt José Augusto AG Berg Macello S Maciel Felipe JF Coimbra Luiz Henrique O Schiavon Maria Dirlei Begnami Marcos D Guimares Charles E Zurstrassen Rubens Chojniak | 2015 | World Journal of Gastroenterology2015，21，12： | 14 |
| 2 | Helicobacter pylori and corpus gastric pathology are associated with lower serum ghrelin显示文摘AIM To evaluate the association of Helicobacter pylori(H. pylori), cag A genotype, and type of gastric pathology with ghrelin, leptin and nutritional status.METHODS Fasted dyspeptic adults(18-70 years) referred for an upper digestive endoscopy were enrolled in this crosssectional study. Height and weight were assessed for body mass index(BMI) calculation. A sociodemographic survey was administered and nutrient intake was evaluated with 24 h dietary recalls. Serum total ghrelin and leptin levels were analyzed by enzymelinked immunosorbent assay. 13 C-Urea Breath Test was performed and four gastric biopsies were obtained during endoscopy for histopathology and H. pylori DNA amplification and genotyping. Data analysis was performed using χ2, Mann-Whitney U, Kruskal-Wallis tests, Spearman's correlation and linear regression.RESULTS One hundred and sixty-three patients(40.8 ± 14.0 years), 98/65 females/males, were included. Overall, persistent H. pylori prevalence was 53.4%(95%CI: 45.7%-65.8%). Neither nutrient intake nor BMI differed significantly between H. pylori positive and negative groups. Serum ghrelin was significantly lower in infected patients [median 311.0 pg/m L(IQR 230.0-385.5)] than in uninfected ones [median 355.0 pg/m L(IQR 253.8-547.8)](P = 0.025), even after adjusting for BMI and gender(P = 0.03). Ghrelin levels tended to be lower in patients carrying cag A positive strains both in the antrum and the corpus; however, differences with those carrying cag A negative strains did not reach statistical significance(P = 0.50 and P = 0.49, respectively). In addition, the type and severity of gastric pathology in the corpus was associated with lower serum ghrelin(P = 0.04), independently of H.pylori status. Conversely, leptin levels did not differ significantly between infected and uninfected patients [median 1.84 ng/m L(0.80-4.85) vs 1.84 ng/m L(0.50-5.09),(P = 0.51)]. CONCLUSION H. pylori infection and severity of gastric corpus pathology are associated with lower serum ghrelin. Further studies could confirm a lower ghrelin prevalence in cag A-positive patients. | Paula Mantero Gonzalo Sebastián Matus Rodolfo Ernesto Corti Ana María Cabanne Gerardo Gabriel Zerbetto de Palma Liliana Marchesi Olid María Marta Piskorz Marcela Beatriz Zubillaga Mariana Andrea Janjetic Cinthia Gabriela Goldman | 2018 | World Journal of Gastroenterology2018，24，3： | 8 |
| 3 | Proteomics for discovery of candidate colorectal cancer biomarkers显示文摘Colorectal cancer(CRC)is the second most common cause of cancer-related deaths in Europe and other Western countries,mainly due to the lack of wellvalidated clinically useful biomarkers with enough sensitivity and specificity to detect this disease at early stages.Although it is well known that the pathogenesis of CRC is a progressive accumulation of mutations in multiple genes,much less is known at the proteome level.Therefore,in the last years many proteomic studies have been conducted to find new candidate protein biomarkers for diagnosis,prognosis and as therapeutic targets for this malignancy,as well as to elucidate the molecular mechanisms of colorectal carcinogenesis.An important advantage of the proteomic approaches is the capacity to look for multiple differentially expressed proteins in a single study.This review provides an overview of the recent reports describing the different proteomic tools used for the discovery of new protein markers for CRC such as two-dimensional electrophoresis methods,quantitative mass spectrometry-based techniques or protein microarrays.Additionally,we will also focus on the diverse biological samples used for CRC biomarker discovery such as tissue,serum and faeces,besides cell lines and murine models,discussing their advantages and disadvantages,and summarize the most frequently identified candidate CRC markers. | Paula lvarez-Chaver Olalla Otero-Estévez María Páez de la Cadena Francisco J Rodríguez-Berrocal Vicenta S Martínez-Zorzano | 2014 | World Journal of Gastroenterology2014，20，14： | 7 |
| 4 | Impact of an acute hemodynamic response-guided protocol for primary prophylaxis of variceal bleeding显示文摘AIM To evaluate the long-term outcome of an acute hemodynamic response-guided protocol in which acute responders to intravenous propranolol received traditional nonselective beta-blockers(NSBBs) and acute nonresponders received carvedilol.METHODS Retrospective review of a protocol for primary prophylaxis of variceal bleeding guided by the acute hemodynamic response to intravenous propranolol. Fifty-two acute responders treated with traditional NSBB(i.e. propranolol or nadolol) were compared with 24 acute nonresponders receiving carvedilol. A second hemodynamic study was performed in 27 and 13 patients, respectively. The primary endpoint was development of first or further decompensation. Secondary endpoints included death from any cause, association between acute and chronic hemodynamic response, and baseline clinical and laboratory variables related to the acute hemodynamic response.RESULTS Acute responders and acute nonresponders presented similar 1, 2, and 3-year probabilities of first decompensation(NSBB: 0%, 13.7%, 26.1% vs carvedilol: 0%, 20%, 20%, P = 0.968) or further decompensation(21.2%, 26.1%, 40.9% vs 21.2%, 50.0%, 50.0%, P = 0.525). A previous episode of hepatic encephalopathy was the only independent predictor of decompensation [hazard ratio(95% confidence interval): 8.03(2.76-23.37)]. Mortality rates were similar in acute responders and acute nonresponders with compensated(P = 0.428) or decompensated cirrhosis(P = 0.429). No clinical, laboratory, endoscopic or hemodynamic parameter predicted the acute hemodynamic response. In patients receiving traditional NSBB, the acute and chronic changes of hepatic venous pressure gradient were correlated(r = 0.59, P = 0.001). Up to 69.2% of acute nonresponders gained chronic response with carvedilol.CONCLUSION Early identification and treatment with carvedilol of acute nonresponders to intravenous propranolol improves the clinical outcome of this high-risk group of patients, probably due to its greater effects for reducing portal pressure. | José Ignacio Fortea ángela Puente Patricia Ruiz Iranzu Ezcurra Javier Vaquero Antonio Cuadrado María Teresa Arias-Loste Joaquín Cabezas Susana Llerena Paula Iruzubieta Carlos Rodríguez-Lope Patricia Huelin Fernando Casafont Emilio Fábrega Javier Crespo | 2018 | World Journal of Clinical Cases2018，6，13： | 6 |

| 7 | Expression and function of renal and hepatic organic anion transporters in extrahepatic cholestasis显示文摘Obstructive jaundice occurs in patients suffering from cholelithiasis and from neoplasms affecting the pancreas and the common bile duct.The absorption,distribution and elimination of drugs are impaired during this pathology.Prolonged cholestasis may alter both liver and kidney function.Lactam antibiotics,diuretics,non-steroidal anti-inflammatory drugs,several antiviral drugs as well as endogenous compounds are classified as organic anions.The hepatic and renal organic anion transport pathways play a key role in the pharmacokinetics of these compounds.It has been demonstrated that acute extrahepatic cholestasis is associated with increased renal elimination of organic anions.The present work describes the molecular mechanisms involved in the regulation of the expression and function of the renal and hepatic organic anion transporters in extrahepatic cholestasis,such as multidrug resistanceassociated protein 2,organic anion transporting polypeptide 1,organic anion transporter 3,bilitranslocase,bromosulfophthalein/bilirubin binding protein,organic anion transporter 1 and sodium dependent bile salt transporter.The modulation in the expression of renal organic anion transporters constitutes a compensatory mechanism to overcome the hepatic dysfunction in the elimination of organic anions. | Anabel Brandoni María Herminia Hazelhoff Romina Paula Bulacio Adriana Mónica Torres | 2012 | World Journal of Gastroenterology2012，18，44： | 5 |
| 8 | T_3-induced liver AMP-activated protein kinase signaling:Redox dependency and upregulation of downstream targets显示文摘AIM:To investigate the redox dependency and promotion of downstream targets in thyroid hormone(T3)-induced AMP-activated protein kinase(AMPK)signaling as cellular energy sensor to limit metabolic stresses in the liver.METHODS:Fed male Sprague-Dawley rats were given a single ip dose of 0.1 mg T3/kg or T3 vehicle(Na OH0.1 N;controls)and studied at 8 or 24 h after treatment.Separate groups of animals received 500 mg N-acetylcysteine(NAC)/kg or saline ip 30 min prior T3.Measurements included plasma and liver 8-isoprostane and serumβ-hydroxybutyrate levels(ELISA),hepaticlevels of m RNAs(q PCR),proteins(Western blot),and phosphorylated AMPK(ELISA).RESULTS:T3 upregulates AMPK signaling,including the upstream kinases Ca2+-calmodulin-dependent protein kinase kinase-βand transforming growth factor-β-activated kinase-1,with T3-induced reactive oxygen species having a causal role due to its suppression by pretreatment with the antioxidant NAC.Accordingly,AMPK targets acetyl-Co A carboxylase and cyclic AMP response element binding protein are phosphorylated,with the concomitant carnitine palmitoyltransferase-1α(CPT-1α)activation and higher expression of peroxisome proliferator-activated receptor-γco-activator-1αand that of the fatty acid oxidation(FAO)-related enzymes CPT-1α,acyl-Co A oxidase 1,and acylCo A thioesterase 2.Under these conditions,T3 induced a significant increase in the serum levels ofβ-hydroxybutyrate,a surrogate marker for hepatic FAO.CONCLUSION:T3 administration activates liver AMPK signaling in a redox-dependent manner,leading to FAO enhancement as evidenced by the consequent ketogenic response,which may constitute a key molecular mechanism regulating energy dynamics to support T3preconditioning against ischemia-reperfusion injury. | Luis A Videla Virginia Fernández Pamela Cornejo Romina Vargas Paula Morales Juan Ceballo Alvaro Fischer Nicolás Escudero Oscar Escobar | 2014 | World Journal of Gastroenterology2014，20，46： | 3 |

| 11 | S-adenosyl-L-methionine modifies antioxidant-enzymes,glutathione-biosynthesis and methionine adenosyltransferases-1/2 in hepatitis C virus-expressing cells显示文摘AIM: To elucidate the mechanism(s) by which S-adenosyl-L-methionine(SAM) decreases hepatitis C virus(HCV) expression.METHODS: We examined the effects of SAM on viral expression using an HCV subgenomic replicon cell culture system. Huh7 HCV-replicon cells were treated with 1 mmol/L SAM for different times(24-72 h), then total RNA and proteins were isolated. c DNA was synthesized and real time-PCR was achieved to quantify HCV-RNA, superoxide dismutase 1 and 2(SOD-1, SOD-2) catalase, thioredoxin 1, methionine adenosyltransferase 1A and 2A(MAT1A, MAT2A) expression, and GAPDH and RPS18 as endogenous genes. Expression of cellular and viral protein was evaluated by western-blot analysis using antibodies vs HCV-NS5 A, SOD-1, SOD-2, catalase, thioredoxin-1, MAT1 A, MAT2 A, GAPDH and actin. Total glutathione levels were measured at different times by Ellman's recycling method(0-24 h). Reactive oxidative species(ROS) levels were quantified by the dichlorofluorescein assay(0-48 h); Pyrrolidin dithiocarbamate(PDTC) was tested as an antioxidant control and H2O2 as a positive oxidant agent.RESULTS: SAM exposition decreased HCV-RNA levels 50%-70% compared to non-treated controls(24-72 h). SAM induced a synergic antiviral effect with standard IFN treatment but it was independent of IFN signaling. In addition, 1 mmol/L SAM exposition did not modify viral RNA stability, but it needs cellular translation machinery in order to decrease HCV expression. Total glutathione levels increased upon SAM treatment in HCV-replicon cells. Transcriptional antioxidant enzyme expression(SOD-1, SOD-2 and thioredoxin-1) was increased at different times but interestingly, there was no significant change in ROS levels upon SAM treatment, contrary to what was detected with PDTC treatment, where an average 40% reduction was observed in exposed cells. There was a turnover from MAT1A/MAT2 A, since MAT1 A expression was increased(2.5 fold-times at 48 h) and MAT2 A was diminished(from 24 h) upon SAM treatment at both the transcriptional and translational level. CONCLUSION: A likely mechanism(s) by which SAM diminish HCV expression could involve modulating antioxidant enzymes, restoring biosynthesis of glutathione and switching MAT1/MAT2 turnover in HCV expressing cells. | Sonia Amelia Lozano-Sepulveda Eduardo Bautista-Osorio Jose Angel Merino-Mascorro Marta Varela-Rey Linda Elsa Munoz-Espinosa Paula Cordero-Perez María Luz Martinez-Chantar Ana Maria Rivas-Estilla | 2016 | World Journal of Gastroenterology2016，22，14： | 2 |
