6Surgical vs percutaneous radiofrequency ablation for hepatocellular carcinoma in dangerous locations显示文摘AIM:To compare the long-term outcome of percutaneous vs surgical radiofrequency ablation(RFA) for hepatocellular carcinoma(HCC) in dangerous locations.METHODS:One hundred and sixty-two patients with HCC in dangerous locations treated with percutaneous or surgical RFA were enrolled in this study.The patients were divided into percutaneous RFA group and surgical RFA group.After the patients were regularly followed up for a long time,their curative rate,hospital stay time,postoperative complications and 5-year local tumor progression were compared and analyzed.RESULTS:No significant difference was observed in curative rate between the two groups(91.3% vs 96.8%,P = 0.841).The hospital stay time was longer and more analgesics were required while the incidence of bile duct injury and RFA-related hemorrhage was lower in surgical RFA group than in percutaneous RFA group(P < 0.05).The local progression rate of HCC in dangerous locations was significantly lower in surgical RFA group than in percutaneous RFA group(P = 0.05).The relative risk of local tumor progression was 14.315 in percutaneous RFA group.CONCLUSION:The incidence of severe postoperative complications and local tumor progression is lower after surgical RFA than after percutaneous RFA.Ji-Wei Huang Roberto Hernandez-Alejandro Kristopher P Croome Lu-Nan Yan Hong Wu Zhe-Yu Chen Pankaj Prasoon Yong Zeng 2011World Journal of Gastroenterology2011,17,1:14
7MicroRNA regulation of innate immune responses in epithelial cells显示文摘Mucosal surface epithelial cells are equipped with several defense mechanisms that guard against pathogens.Recent studies indicate that microRNAs(miRNAs)mediate post-transcriptional gene suppression and may be a critical component of the complex regulatory networks in epithelial immune responses.Transcription of miRNA genes in epithelial cells can be elaborately controlled through pathogen recognition receptors,such as Toll-like receptors(TLRs),and associated nuclear factor kappaB(NF-kB)and mitogen-activated protein kinase(MAPK)pathways,and ultimately nuclear transcription factor associated-transactivation and transrepression.Activation of these intracellular signaling pathways may also modulate the process of miRNA maturation.Functionally,miRNAs may modulate epithelial immune responses at every step of the innate immune network,including production and release of cytokines/chemokines,expression of adhesion and costimulatory molecules,shuttling of miRNAs through release of exosomes and feedback regulation of immune homeostasis.Therefore,miRNAs act as critical regulators to the fine-tuning of epithelial immune responses.Rui Zhou Steven P O’Hara Xian-Ming Chen 2011Cellular & Molecular Immunology2011,8,5:13

12Percutaneous transgastric computed tomography-guided biopsy of the pancreas using large needles显示文摘AIM:To assess the safety,yield and clinical utility of percutaneous transgastric computed tomography(CT)-guided biopsy of pancreatic tumor using large needles, in selected patients. METHODS:We reviewed 34 CT-guided biopsies in patients with pancreas mass,of whom 24(71%)had a direct path to the mass without passing through a major organ.The needle passed through the liver in one case(3%).Nine passes(26%)were made through the stomach.These nine transgastric biopsies which used a coaxial technique(i.e.a 17-gauge coaxial introducer needle and an 18-gauge biopsy needle)were the basis of this study.Immediate and late follow-up CT images to detect complications were obtained. RESULTS:Tumor tissues were obtained in nine pancreatic biopsies,and histologic specimens for diagnosis were obtained in all cases.One patient,who had a rare sarco-matoid carcinoma,received a second biopsy.One patient had a complication of transient pneumoperitoneum but no subjective complaints.An immediate imaging study and clinical follow-up detected neither hemorrhage nor peritonitis.No delayed procedure-related complication was seen during the survival period of our patients.CONCLUSION:Pancreatic biopsy can be obtained by a transgastric route using a large needle as an alternative method,without complications of peritonitis or bleeding.Hsiuo-Shan Tseng Chia-Yuen Chen Wing P Chan Jen-Huey Chiang 2009World Journal of Gastroenterology2009,15,47:11

14Multivariate statistical analysis of clinicopathologic factors influencing survival of patients with bile duct carcinoma显示文摘AIM: To evaluate the influence of various clinicopathologicfactors on survival of patients with bile duct carcinoma aftercurative resection.METHODS: A retrospective analysis was made for 86 casesof bile duct carcinoma treated from January 1981 toSeptember 1995. Fifteen clinicopathologic factors possiblyinfluencing survival were selected. Independent variableswere first analyzed by univariate methods. Survival forvariable was estimated by the method of Kaplan and Meier.The variables that were statistically significant by univarlateanalysis were included in a multivariate analysis, which wereconfirmed using the Cox stepwise proportion hazard modelwith the help of SPSS 10.0 for Windows software.RESULTS: The overall cumulative survival rate was 72.6 %at 1 year, 32.4 % at 3 years, and 18.7 % at 5 years. Theresults of univariate analysis showed that the majorsignificant prognostic factors influencing survival of thesepatients were histological type of lesion, lymph nodemetastasis, pancreatic invasion, duodenal invasion, pedneuralinvasion, macroscopic vessel involvement, resected surgicalmargin and depth of cancer invasion (P=0.02, 0.02, 0.004,0.005, 0.01, 0.43, 0.03 and 0.04). Age, sex, location of tumor,size of tumor, macroscopic type of lesions, hepaticmetastasis, and hepatic invasion were not significantlyassociated with prognosis (P>0.05). Pancreatic invasion,perineural invasion and lymph node metastases were thethree most important prognostic factors by multivariateanalysis using the Cox proportional hazards model.CONCLUSION: Pancreatic invasion, pedneural invasion andlymph node metastases are the most important prognosticfactors for bile duct carcinoma after curative resection.He, P Shi, JS Chen, WK Wang, ZR Ren, H Li, H 2002World Journal of Gastroenterology2002,8,5:10
15Up-regulation of mitochondrial chaperone TRAP1 in ulcerative colitis associated colorectal cancer显示文摘AIM:To characterize tumor necrosis factor receptorassociated protein 1(TRAP1)expression in the progression of ulcerative colitis(UC)-associated colorectal cancer.METHODS:Chronic UC is an inflammatory bowel disease that predisposes to colorectal cancer.Immunohistochemical analysis was used to evaluate TRAP1expression on tissue microarrays containing colonic tissues from 42 UC progressors(patients with cancer or dysplasia)and 38 non-progressors(dysplasia/cancer free patients).Statistical analyses of the TRAP1immunohistochemistry staining were performed using Graph Pad Prism.Differences in the TRAP1 level between non-progressors and progressors were tested for statistical significance using the Mann-Whitney test.Receiver operating characteristic curve method was used to quantify marker performance in distinguishing diseased cases from controls.RESULTS:TRAP1 was up-regulated in the colon tissues from UC progressors,but not in the colon tissues from UC non-progressors.Moreover,up-regulation of TRAP1 preceded the neoplastic changes:it was present in both the dysplastic and non-dysplastic tissues of UC progressors.When TRAP1 staining in rectal tissue was used as a diagnostic marker,it could distinguish progressors from non-progressors with 59%sensitivity and 80%specificity.Our study further showed that the increase of TRAP1 expression positively correlated with the degree of inflammation in the colorectal cancer tissues,which could be related to the increased oxidation present in the colonic mucosa from UC progressors.We then investigated the cellular proteome changes underlying oxidative stress,and found that oxidative stress could induce up-regulation of TRAP1 along with several other negative modulators of apoptosis.CONCLUSION:These results suggest that oxidative stress in long standing UC could lead to the increase of cytoprotective protein TRAP1,which in turn could promote cancer progression by preventing or protecting the oxidative damaged epithelial cells from undergoing apoptosis.TRAP1 could be a potential diagnostic marker for UC associated colorectal cancer.Ru Chen Sheng Pan Keith Lai Lisa A Lai David A Crispin Mary P Bronner Teresa A Brentnall 2014World Journal of Gastroenterology2014,20,45:9

20Effect of age on aortic atherosclerosis显示文摘Objective To examine the association of atherosclerosis burden in the survivors of an asymptomatic elderly cohort study and its relationship to other coronary risk factors (specifically, age) by evaluating aortic atherosclerotic wall burden by magnetic resonance imaging (MRI). Methods A total of 312 participants in an ongoing observational cohort study underwent cardiac and descending thoracic aorta imaging by MRI. Maximum wall thickness was measured and the mean wall thickness calculated.Wall/outer wall ratio was used as a normalized wall index (NWI) adjusted for artery size difference among participants. Percent wall volume (PWV) was calculated as NWI ×100.Results In this asymptomatic cohort (mean age: 76 years), the mean (SD) aortic wall area andwall thicknesswere 222 ±45 mm2 and 2.7 ±0.4 mm, respectively. Maximum wall thickness was 3.4 ±0.6 mm, and PWV was 32% ±4%. Women appeared to have smaller wall area,but after correcting for their smaller artery size, had significantly higher PWV than men (P = 0.03). Older age was associatedwith larger wall area (P = 0.04 for trend) with similar PWVs. However, there were no statistically significant associations between standard risk factors,Framingham global risk, or metabolic syndrome status, therapy for cholesterol or hypertension, coronary or aortic calcium score, and the aortic wall burden. Aortic calcificationwas associated with coronary calcification. Conclusions Asymptomatic elderly in this cohort had a greater descending thoracic aortic wall volume that correlated with age, andwomen had a significantly increased PWV compared to men. In these survivors, the atherosclerotic aortic wall burden was not significantly associated with traditional risk factors or with coronary or aortic calcium scores or coronary calcium progression. Results suggest that age, or as yet unidentified risk factor(s), may be responsible for the increase in atherosclerosis.Michael A. Chen Miwa Kawakubo Patrick M.
