| 1 | Significant association between ABO blood group and pancreatic cancer显示文摘AIM:To evaluate whether the ABO blood group is related to pancreatic cancer risk in the general population of the United States.METHODS:Using the University of Pittsburgh's clinicalpancreatic cancer registry,the blood donor database from our local blood bank (Central Blood Bank),and the blood product recipient database from the regional transfusion service (Centralized Transfusion Service) in Pittsburgh,Pennsylvania,we identified 274 pancreatic cancer patients with previously determined serological ABO blood group information.The ABO blood group frequency was compared between these patients and 708842 individual,community-based blood donors who had made donations to Pittsburgh's Central Blood Bank between 1979 and 2009.RESULTS:The frequency of blood group A was statistically significantly higher amongst pancreatic cancer patients compared to its frequency amongst the regional blood donors [47.63% vs 39.10%,odds ratio (OR)=1.43,P=0.004].Conversely,the frequency of blood group O was significantly lower amongst pancreatic cancer patients relative to the community blood donors (32.12% vs 43.99%,OR=0.60,P=0.00007).There were limited blood group B (n=38) and AB (n=17) pancreatic cancer patients;the overall P trend value comparing patient to donor blood groups was 0.001.CONCLUSION:The ABO blood group is associated with pancreatic cancer risk.Future studies should examine the mechanism linking pancreatic cancer risk to ABO blood group. | Julia B Greer Mark H Yazer Jay S Raval M Michael Barmada Randall E Brand David C Whitcomb | 2010 | World Journal of Gastroenterology2010，16，44： | 10 |
| 2 | Vanishing bile duct syndrome in human immunodeficiency virus infected adults:A report of two cases显示文摘Vanishing bile duct syndrome(VBDS) is a group of rare disorders characterized by ductopenia,the progressive destruction and disappearance of intrahepatic bile ducts leading to cholestasis.Described in association with medications,autoimmune disorders,cancer,transplantation,and infections,the specific mechanisms of disease are not known.To date,only 4 cases of VBDS have been reported in human immunodeficiency virus(HIV) infected patients.We report 2 additional cases of HIV-associated VBDS and review the features common to the HIV-associated cases.Presentation includes hyperbilirubinemia,normal liver imaging,and negative viral and autoimmune hepatitis studies.In HIV-infected subjects,VBDS occurred at a range of CD4+ T-cell counts,in some cases following initiation or change in antiretroviral therapy.Lymphoma was associated with two cases;nevirapine,antibiotics,and viral co-infection were suggested as etiologies in the other cases.In HIV-positive patients with progressive cholestasis,early identification of VBDS and referral for transplantation may improve outcomes. | Ana Paula Oppenheimer Christopher Koh Mary McLaughlin John C Williamson Thomas D Norton Jennifer Laudadio Theo Heller David E Kleiner Kevin P High Caryn G Morse | 2013 | World Journal of Gastroenterology2013，19，1： | 8 |
| 3 | Association between calcium sensing receptor gene polymorphisms and chronic pancreatitis in a US population:Role of serine protease inhibitor Kazal 1type and alcohol显示文摘AIM: To test the hypothesis that calcium sensing receptor (CASR) polymorphisms are associated with chronic pancreatitis (CP), and to determine whether serine protease inhibitor Kazal 1type (SPINK1) N34S oralcohol are necessary co-factors in its etiology. METHODS: Initially, 115 subjects with pancreatitis and 66 controls were evaluated, of whom 57 patients and 21 controls were predetermined to carry the high-risk SPINK1 N34S polymorphism. We sequenced CASR gene exons 2, 3, 4, 5 and 7, areas containing the majority of reported polymorphisms and novel mutations. Based on the initial results, we added 223 patients and 239 controls to analyze three common nonsynonymous single nucleotide polymorphisms (SNPs) in exon 7 (A986S, R990G, and Q1011E). RESULTS: The CASR exon 7 R990G polymorphism was signifi cantly associated with CP (OR, 2.01; 95% CI, 1.12-3.59; P = 0.015). The association between CASR R990G and CP was stronger in subjects who reported moderate or heavy alcohol consumption (OR, 3.12; 95% CI, 1.14-9.13; P = 0.018). There was no association between the various CASR genotypes and SPINK1 N34S in pancreatitis. None of the novel CASR polymorphisms reported from Germany and India was detected. CONCLUSION: Our United States-based study confirmed an association of CASR and CP and for the first time demonstrated that CASR R990G is a signifi cant risk factor for CP. We also conclude that the risk of CP with CASR R990G is increased in subjects with moderate to heavy alcohol consumption. | Venkata Muddana Janette Lamb Julia B Greer Beth Elinoff Robert H Hawes Peter B Cotton Michelle A Anderson Randall E Brand Adam Slivka David C Whitcomb | 2008 | World Journal of Gastroenterology2008，14，28： | 7 |

| 8 | H pylori receptor MHC classⅡcontributes to the dynamic gastric epithelial apoptotic response显示文摘AIM: To investigate the role of MHC classⅡin the modulation of gastric epithelial cell apoptosis induced by H pylon infection. METHODS: After stimulating a human gastric epithelial cell line with bacteria or agonist antibodies specific for MHC classⅡand CD95, the quantitation of apoptotic and anti-apoptotic events, including caspase activation, BCL-2 activation, and FADD recruitment, was performed with a fluorometric assay, a cytometric bead array, and confocal microscopy, respectively. RESULTS: Pretreatment of N87 cells with the anti-MHC classⅡIgM antibody RFD1 resulted in a reduction in global caspase activation at 24 h of H pylori infection. When caspase 3 activation was specifically measured, crosslinking of MHC class n resulted in markedly reduced caspase activation, while simple ligation of MHC classⅡdid not. Crosslinking of MHC class n also resulted in an increased activation of the anti-apoptosis molecule BCL-2 compared to simple ligation. Confocal microscope analysis demonstrated that the pretreatment of gastric epithelial cells with a crosslinking anti-MHC classⅡIgM blocked the recruitment of FADD to the cell surface. CONCLUSION: The ability of MHC class n to modulate gastric epithelial apoptosis is at least partially dependent on its crosslinking. The crosslinking of this molecule has anti-apoptotic effects during the earlier time points of H pylori infection. This effect is possibly mediated by the ability of MHC classⅡto modulate the activation of the pro-apoptotic receptor Fas by blocking the recruitment of the accessory molecule FADD, and this delay in apoptosis induction could allow for prolonged cytokine secretion by H pylori-infected gastric epithelial cells. | David A Bland Giovanni Suarez Ellen J Beswick Johanna C Sierra Victor E Reyes | 2006 | World Journal of Gastroenterology2006，12，29： | 3 |
| 9 | Chromodomain-helicase-DNA binding protein 5, 7 and pronecrotic mixed lineage kinase domain-like protein serve as potential prognostic biomarkers in patients with resected pancreatic adenocarcinomas显示文摘Pancreatic cancer is one of the deadliest cancers with a very poor prognosis. Recently, there has been a significant increase in research directed towards identifying potential biomarkers that can be used to diagnose and provide prognostic information for pancreatic cancer. These markers can be used clinically to optimize and personalize therapy for individual patients. In this review, we focused on 3 biomarkers involved in the DNA damage response pathway and the necroptosis pathway: Chromodomainhelicase-DNA binding protein 5, chromodomain-helicaseDNA binding protein 7, and mixed lineage kinase domain-like protein. The aim of this article is to review present literature provided for these biomarkers and current studies in which their effectiveness as prognostic biomarkers are analyzed in order to determine their future use as biomarkers in clinical medicine. Based on the data presented, these biomarkers warrant further investigation,and should be validated in future studies. | Crystal S Seldon Lauren E Colbert William A Hall Sarah B Fisher David S Yu Jerome C Landry | 2016 | World Journal of Gastrointestinal Oncology2016，8，4： | 2 |
| 10 | Outcomes after arthroscopic repair of rotator cuff tears in the setting of mild to moderate glenohumeral osteoarthritis显示文摘BACKGROUND Rotator cuff pathology is a very common source of shoulder pain.Similarly,osteoarthritis of the glenohumeral joint can cause shoulder pain and produce similar symptoms.Surgical management can be indicated for both pathologies,however,outcomes data is limited when examining rotator cuff repair(RCR) in the setting of glenohumeral arthritis(GHOA).Thus,this study sought to determine outcomes for patients who undergo RCR in the setting of GHOA.AIM To evaluate if a relationship exists between outcomes of RCR in the setting of GHOA.METHODS This was a retrospective analysis of patients who underwent arthroscopic rotator cuff repair with concurrent glenohumeral osteoarthritis between 2010-2017.Patients were stratified based on rotator cuff tear size and glenohumeral osteoarthritis severity.Cohorts were paired 1:1 with patients without glenohumeral osteoarthritis.Patients included had a minimum two year follow-up.Rate of conversion to total shoulder arthroplasty,complication rates following initial surgery,and patient-reported outcome measures were collected.RESULTS A total of 142 patients were included.The number of patients that required total shoulder arthroplasty within two years after index surgery was low.2/71(2.8%) patients with GHOA,and 1/71(1.4%) without GHOA.Following rotator cuff repair,both groups showed favorable patientreported outcomes.CONCLUSION Patients with glenohumeral osteoarthritis who underwent arthroscopic rotator cuff repair showed comparable outcomes to patients without glenohumeral osteoarthritis. | Ian S Hong Allison J Rao Tyler L CarlLee Joshua D Meade Daniel J Hurwit Gregory Scarola David P Trofa Shadley C Schiffern Nady Hamid Patrick M Connor James E Fleischli Bryan Michael Saltzman | 2022 | World Journal of Orthopedics2022，13，7： | 2 |

When caspase 3 activation was specifically measured, crosslinking of MHC class Ⅱ resulted in a marked re-duced caspase activation, while simple ligation of MHC class Ⅱ did not. Crosslinking of MHC class Ⅱ also re-sulted in an increased activation of the anti-apoptosis molecule BCL-2 compared to simple ligation. Confocal microscope analysis demonstrated that the pretreatment of gastric epithelial cells with a crosslinking anti-MHC class Ⅱ IgM blocked the recruitment of FADD to the cell surface.CONCLUSION: The results presented here demonstrate that the ability of MHC class Ⅱ to modulate gastric epi-thelial apoptosis is at least partially dependent on its crosslinking. Furthermore, while previous research has demonstrated that MHC class Ⅱ signaling can be pro-apoptotic during extended ligation, we have shown that the crosslinking of this molecule has anti-apoptotic ef-fects during the earlier time points of H pylori infection. This effect is possibly mediated by the ability of MHC class Ⅱ to modulate the activation of the pro-apoptotic receptor Fas by blocking the recruitment of the accessory molecule FADD, and this delay in apoptosis induction could allow for prolonged cytokine secretion by H pylori-infected gastric epithelial cells. | David A Bland Giovanni Suarez Ellen J Beswick Johanna C Sierra Victor E Reyes | 2006 | World Journal of Gastroenterology2006，12，33： | 2 |

| 15 | Changes in efficiency and resource utilization after increasing experience with double balloon enteroscopy显示文摘AIM:To investigate changes in efficiency and resource utilization as a single endoscopist's experience increased with each subsequent 100 double balloon enteroscopy(DBE) procedures.METHODS:We reviewed consecutive DBE procedures performed by a single endoscopist at our center over 4 years.DBE was employed when the clinician deemed the procedure was needed for disease management.The approach(oral,anal or both) was chosen based on suspected location of the target lesion.All DBE was performed in a standard endoscopy room with a portable fluoroscopy unit.Fluoroscopy was used to aid in shortening the small intestine and reducing bowel loops.For oral DBE,measurements were taken from the incisors.For anal DBE,measurements were taken from the anal verge.Enteroscopy continued until the target lesion was reached,until the entire small intestine was examined,or until no further progress was deemed possible.The length of small intestine examined(cm),procedure duration(min),and fluoroscopy time(s) were analyzed for sequential groups of 100 DBE.Sub-groups of diagnostic and therapeutic procedures were analyzed using multivariable linear regression.RESULTS:802 consecutive DBE procedures were analyzed.For oral DBE,median [interquartile range(IQR)] length of small bowel examined was 230.8 cm(range:210-248 cm) and for anal DBE was 143.5 cm(range:100-180 cm).No significant increase in length examined was noted for either the oral or anal approach with advancing position in series.In terms of duration of procedure,the median(IQR) for oral DBE was 86 min(range:71-105 min) and for anal DBE was 81.3 min(range:67-105 min).When comparing by the position in series,there was a significant(P value < 0.001) decrease in procedure duration for both upper and lower procedures with increasing experience.Median(IQR) time of exposure to fluoroscopy for oral DBE was 190 s(114-275) compared to anal DBE which was 196.4 s(312-128).This represented a significant(P value < 0.001) decrease in the amount of fluoroscopy used with increasing position in series.For both oral and anal DBE,fluoroscopy time was reduced by greater than 50% over the course of 802 total procedures performed.Sub-group analysis was conducted on therapeutic and diagnostic groups.Out of 802 procedures,a total of 434 were considered therapeutic.Argon plasma coagulation was by far the most common therapeutic intervention performed.There was no evidence of a difference in length examined or fluoroscopy exposure among oral DBE for diagnostic and therapeutic procedures,P = 0.91 and P = 0.32 respectively.The median(IQR) for length was 235 cm(range:178-280 cm) for diagnostic vs 230 cm(range:180-275 cm) for therapeutic procedures;additionally,fluoroscopy time median(IQR) was 180 s(range:110-295 s) and 162 s(range:102-263 s) for no intervention and intervention.However,there was a significant difference in procedure duration among oral DBE(P < 0.001).The median(IQR) was 80 min(range:60-97 min) and 94 min(range:77-110 min) for diagnostic and therapeutic interventions respectively.CONCLUSION:For a single endoscopist,increased DBE experience with number of performed procedures is associated with increased efficiency and decreased resource utilization. | Neal C Patel William C Palmer Kanwar R Gill David Cangemi Nancy Diehl Mark E Stark | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，3： | 2 |
