1Pancreatic regenerating protein (regⅠ) and regⅠreceptor mRNA are upregulated in rat pancreas after induction of acute pancreatitis显示文摘AIM: Pancreatic regenerating protein (regⅠ) stimulates pancreatic regeneration after pancreatectomy and is mitogenic to ductal andβ-cells. This suggests that regⅠand its receptor may play a role in recovery after pancreatic injury. We hypothesized that regⅠand its receptor are induced in acute pancreatitis. METHODS: Acute pancreatitis was induced in male Wistar rats by retrograde injection of 3% sodium taurocholate into the pancreatic duct. Pancreata and serum were collected 12, 24, and 36 hours after injection and from normal controls (4 rats/group). RegⅠreceptor mRNA, serum regⅠprotein, and tissue regⅠprotein levels were determined by Northern analysis, enzyme-linked immunosorbent assay (ELISA), and Western analysis, respectively. Immunohistochemistry was used to localize changes in regⅠand its receptor. RESULTS: Serum amylase levels and histology confirmed necrotizing pancreatitis in taurocholate treated rats. There was no statistically significant change in serum regⅠconcentrations from controls. However, Western blot demonstrated increased tissue levels of regⅠat 24 and 36 h. This increase was localized primarily to the acinar cells and the ductal cells by immunohistochemistry. Northern blot demonstrated a significant increase in regⅠreceptor mRNA expression with pancreatitis. Immunohistochemistry localized this increase to the ductal cells, islets, and acinar cells. CONCLUSION: Acute pancreatitis results in increased tissue regⅠprotein levels localized to the acinar and ductal cells, and a parallel threefold induction of regⅠreceptor in the ductal cells, islets, and acinar cells. These changes suggest that induction of reg I and its receptor may be important for recovery from acute pancreatitis.Martin H Bluth Sameer A Patel Brian K Dieckgraefe Hiroshi Okamoto Michael E Zenilman 2006World Journal of Gastroenterology2006,12,28:19
2Retrograde-viewing device improves adenoma detection rate in colonoscopies for surveillance and diagnostic workup显示文摘AIM:To determine which patients might benefit most from retrograde viewing during colonoscopy through subset analysis of randomized,controlled trial data.METHODS:The Third Eye Retroscope Randomized Clinical Evaluation(TERRACE) was a randomized,controlled,multicenter trial designed to evaluate the efficacy of a retrograde-viewing auxiliary imaging device that is used during colonoscopy to provide a second video image which allows viewing of areas on the proximal aspect of haustral folds and flexures that are difficult to see with the colonoscope's forward view.We performed a post-hoc analysis of the TERRACE data to determine whether certain subsets of the patient population would gain more benefit than others from use of the device.Subjects were patients scheduled for colonoscopy for screening,surveillance or diagnostic workup,and each underwent same-day tandem examinations with standard colonoscopy(SC) and Third Eye colonoscopy(TEC),randomized to SC followed by TEC or vice versa.RESULTS:Indication for colonoscopy was screening in 176/345 subjects(51.0%),surveillance after previous polypectomy in 87(25.2%) and diagnostic workup in 82(23.8%).In 4 subjects no indication was specified.Previously reported overall results had shown a net additional adenoma detection rate(ADR) with TEC of 23.2% compared to SC.Relative risk(RR) of missing adenomas with SC vs TEC as the initial procedure was 1.92(P = 0.029).Post-hoc subset analysis shows additional ADRs for TEC compared to SC were 4.4% for screening,35.7% for surveillance,55.4% for diagnostic and 40.7% for surveillance and diagnostic combined.The RR of missing adenomas with SC vs TEC was 1.11(P = 0.815) for screening,3.15(P = 0.014) for surveillance,8.64(P = 0.039) for diagnostic and 3.34(P = 0.003) for surveillance and diagnostic combined.Although a multivariate Poisson regression suggested gender as a possibly significant factor,subset analysis showed that the difference between genders was not statistically significant.Age,bowel prep quality and withdrawal time did not significantly affect the RR of missing adenomas with SC vs TEC.Mean sizes of adenomas detected with TEC and SC were similar at 0.59 cm and 0.56 cm,respectively(P = NS).CONCLUSION:TEC allows detection of significantly more adenomas compared to SC in patients undergoing surveillance or diagnostic workup,but not in screening patients(ClinicalTrials.gov Identifier:NCT01044732).Peter D Siersema Amit Rastogi Anke M Leufkens Paul A Akerman Kassem Azzouzi Richard I Rothstein Frank P Vleggaar Alessandro Repici Giacomo Rando Patrick I Okolo Olivier Dewit Ana Ignjatovic Elizabeth Odstrcil James East Pierre H Deprez Brian P Saunders Anthony N Kalloo Bradley Creel Vikas Singh Anne Marie Lennon Daniel C DeMarco 2012World Journal of Gastroenterology2012,18,26:6
3Model combining pre-transplant tumor biomarkers and tumor size shows more utility in predicting hepatocellular carcinoma recurrence and survival than the BALAD models显示文摘AIM To assess the performance of BALAD, BALAD-2 and their component biomarkers in predicting outcome of hepatocellular carcinoma(HCC) patients after liver transplant.METHODS BALAD score and BALAD-2 class are derived from bilirubin, albumin, alpha-fetoprotein(AFP), Lens culinaris agglutinin-reactive AFP(AFP-L3), and des-gammacarboxyprothrombin(DCP). Pre-transplant AFP, AFP-L3 and DCP were measured in 113 patients transplanted for HCC from 2000 to 2008. Hazard ratios(HR) for recurrence and death were calculated. Univariate and multivariate regression analyses were conducted. C-statistics were used to compare biomarker-based to predictive models. RESULTS During a median follow-up of 12.2 years, 38 patients recurred and 87 died. The HRs for recurrence in patients with elevated AFP, AFP-L3, and DCP defined by BALAD cut-off values were 2.42(1.18-5.00), 1.86(0.98-3.52), and 2.83(1.42-5.61), respectively. For BALAD, the HRs for recurrence and death per unit increased score were 1.48(1.15-1.91) and 1.59(1.28-1.97). For BALAD-2, the HRs for recurrence and death per unit increased class were 1.45(1.06-1.98) and 1.38(1.09-1.76). For recurrence prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs. 0.64, 0.61, 0.53, and 0.53 for BALAD, BALAD-2, Milan, and UCSF, respectively. Similarly, for death prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs 0.65,0.61, 0.52, and 0.50 for BALAD, BALAD-2, Milan, and UCSF. A new model combining biomarkers with tumor size at the time of transplant(S-LAD) demonstrated the highest predictive capability with c-statistics of 0.71 and 0.69 for recurrence and death. CONCLUSION BALAD and BALAD-2 are valid in transplant HCC patients, but less predictive than the three biomarkers in combination or the three biomarkers in combination with maximal tumor diameter(S-LAD).Nicha Wongjarupong Gabriela M Negron-Ocasio Roongruedee Chaiteerakij Benyam D Addissie Essa A Mohamed Kristin C Mara William S Harmsen J Paul Theobald Brian E Peters Joseph G Balsanek Melissa M Ward Nasra H Giama Sudhakar K Venkatesh Denise M Harnois Michael R Charlton Hiroyuki Yamada Alicia Algeciras-Schimnich Melissa R Snyder Terry M Therneau Lewis R Roberts 2018World Journal of Gastroenterology2018,24,12:5
4Gastric hyperplastic polyps causing upper gastrointestinal hemorrhage in a young adult显示文摘Here, we report a case of a young man who presented with a significant upper gastrointestinal bleed treated by endoscopic removal of multiple hyperplastic polyps. Gastric hyperplastic polyps are a relatively uncommon cause of overt gastrointestinal bleeding. While most hyperplastic gastric polyps are asymptomatic, they may present with abdominal pain, iron def iciency anemia or gastric outlet obstruction. These polyps are associated with conditions such as Helicobacter pylori gastritis and atrophic autoimmune gastritis, which predispose the epithelium to chronic inf lammation and epithelial repair.The patient presented to Northwestern Memorial Hospital in July 2011. The polyps were resected by clip-assisted snare polypectomy. Histopathologic assessment of the resected polyps demonstrated multiple, nonulcerative hyperplastic polyps measuring 1.3-1.8 cm in size, without evidence of dysplasia or malignancy. This case describes a young adult patient with multiple, large gastric polyps causing overt gastrointestinal bleeding. This is a rare presentation in a young individual, as these polyps are typically identifi ed in patients older than 60 years of age and less commonly, pediatric populations.Brian J Secemsky Kenika R Robinson Kumar Krishnan Kristina A Matkowskyj Barbara H Jung 2013World Journal of Clinical Cases2013,1,1:2
5Physical activity and nutrition attitudes in obese Hispanic children with non-alcoholic steatohepatitis显示文摘AIM:To assess nutrition,physical activity and health-ful knowledge in obese children with biopsy-proven nonalcoholic steatohepatitis(NASH or NA)compared to children without liver disease.METHODS:Children with biopsy-proven NASH comprised the NASH group.Age,sex and ethnicity matched control groups consisted of obese(OB)and lean(CO) children with no liver disease.Subjects were adminis-tered the School Physical Activity and Nutrition Survey and one blood draw was obtained.RESULTS:Fifty-seven patients were enrolled with a mean age of 12.1±2.1 years,and all were Hispanic.Even though the OB and NA had a similar increased body mass index(%),35%of the NA group always read nutrition labels compared to none in the OB(P<0.05),and more NA children felt their diet is'less healthy'.NA consumed the least amount of fruits with only 25%having≥1 fruit/d vs 45%in OB and 64.7% in CO(P<0.05 NA vs CO).Only 15%of NA subjects performed light exercise vs 35%and 59%of OB and CO groups,respectively(P=0.02).The mean physical activity score was lowest in the NA group(P<0.05).Amongst the subjects with NASH,we found that 100% of patients with grade 2 or 3 fibrosis had a sedentary score>2 compared to only 63.6%of those with grade 1 or no fibrosis(P<0.05).CONCLUSION:Children with NASH had increased sedentary behavior,decreased activity,and fruit intake.Larger studies may determine the benefit of changing these behaviors as treatment for NASH.Lana N Hattar Theresa A Wilson Leanel A Tabotabo E O'Brian Smith Stephanie H Abrams 2011World Journal of Gastroenterology2011,17,39:2
