2Association 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 2008World Journal of Gastroenterology2008,14,28:7
3Risk factors for Barrett’s oesophagus and oesophageal adenocarcinoma:Results from the FINBAR study显示文摘AIM:To investigate risk factors associated with Barrett's oesophagus and oesophageal adenocarcinoma.METHODS:This all-Ireland population-based case-control study recruited 224 Barrett's oesophagus patients,227 oesophageal adenocarcinoma patients and 260 controls.All participants underwent a structured interview with information obtained about potential lifestyle and environmental risk factors.RESULTS:Gastro-oesophageal reflux was associated with Barrett's [OR 12.0(95% CI 7.64-18.7)] and oesophageal adenocarcinoma [OR 3.48(95% CI 2.25-5.41)].Oesophageal adenocarcinoma patients were more likely than controls to be ex-or current smokers [OR 1.72(95% CI 1.06-2.81)and OR 4.84(95% CI 2.72-8.61)respectively] and to have a high body mass index [OR 2.69(95% CI 1.62-4.46)].No significant associations were observed between these risk factors and Barrett's oesophagus.Fruit but not vegetables were negatively associated with oesophageal adenocarcinoma [OR 0.50(95% CI 0.30-0.86)].CONCLUSION:A high body mass index,a diet low in fruit and cigarette smoking may be involved in the progression from Barrett's oesophagus to oesophageal adenocarcinoma.Lesley A Anderson RG Peter Watson Seamus J Murphy Brian T Johnston Harry Comber Jim Mc Guigan John V Reynolds Liam J Murray 2007World Journal of Gastroenterology2007,13,10:5
4Have patients with esophagitis got an increased risk of adenocarcinoma? Results from a population-based study显示文摘AIM: To examine an increased risk of esophageal adenocarcinoma is restricted to patients who develop Barrett's esophagus or whether esophagitis per se is a risk factor for adenocarcinoma.METHODS: A population-based cohort of patients with histological evidence of esophagitis without Barrett's esophagus was constructed using electronic pathology reports relating to all esophageal biopsies in Northern Ireland between 1993 and 1996. Person-years of followup and incident cases of esophageal cancer were calculated by linking the cohort to death files and the Northern Ireland Cancer Registry records. Standardized incidence ratios (SIR) were calculated for esophageal cancers (adenocarcinoma, squamous cell carcinoma (SCC), and histologically unspecified cancers).RESULTS: A total of 2 013 patients in the cohort provided 13 559 patient-years of follow-up (mean follow-up 6.7 years). None of the patients developed adenocarcinoma. Three patients developed SCC, and six developed histologically unspecified cancers. The SIR for all esophageal cancers and for SCC were 2.73 (95%CI 1.25-5.19) and 2.93 (95%CI 0.61-8.59), respectively. In a sensitivity analysis in which all unspecified esophageal cancers were treated as adenocarcinomas, the SIR for adenocarcinoma was 2.64 (0.97-5.75).CONCLUSION: The risk of adenocarcinoma is not elevated in patients with histological evidence of esophagitis without Barrett's esophagus; however, these patients may have a moderately increased risk of SCC.Further studies are required to confirm these findings,which suggest that Barrett's esophagus, not esophagitis,is the key precursor lesion in the development of adenocarcinoma.Seamus J Murphy Lesley A Anderson Brian T Johnston Deirdre A Fitzpatrick Peter RG Watson Pauline Monaghan Liam J Murray 2005World Journal of Gastroenterology2005,11,46:4
5新致病基因在颅缝早闭Crouzon综合征中的初步机制研究显示文摘目的研究Rbp4(Retinol binding protein 4)、Gpc3(Glypican family of growth factor binding protein 3)、C1qtnf3(Collagenous repeat-containing sequence of 26 KDa protein)等新致病基因在颅缝早闭症中的发病机制,为疾病非手术治疗奠定理论基础。方法以Crouzon综合征Fgfr2cC342Y/+小鼠为实验模型,应用MicroCT和组织学染色,研究小鼠颅缝闭合模式;以Fgfr2cC342Y/+模型,RT-qPCR研究Rbp4、Gpc3、C1qtnf3等新致病基因的表达差异,初步探讨其在颅缝闭合过程中的调控作用;以体外培养的Fgfr2cC342Y/+小鼠颅缝细胞为模型,研究基因突变动物细胞增殖与代谢改变。结果获得Fgfr2cC342Y/+小鼠后额缝、冠状缝、人字缝、矢状缝等颅缝闭合模式,随颅骨发育、颅缝闭合,OC(Osteocalcin)、ALP(Alkalinephosphatase)表达增加,目的基因Rbp4、Gpc3、C1qtnf3表达下降,Msx2(Muscle segment homeobox gene 2)表达增加,杂合子与野生型小鼠之间均存在显著统计学差异,与前期人颅缝组织Microarray研究结果一致。Gpc1(Glypican family ofgrowth factor binding protein 1)、FliI(Flightless I)在颅缝闭合中的表达较恒定,野生型与杂合子之间未见明显统计学差异。体外培养Fgfr2cC342Y/+小鼠颅缝细胞,CellTiter96 MTS和Quant-iT Picogreen dsDNA细胞增殖与代谢分析结果显示,Fgfr2功能获得性突变可促进冠状缝细胞的增殖,从而导致成骨增加,颅缝早闭。结论 Fgfr2cC342Y/+模型新致病基因表达趋势与前期人颅缝组织Microarray研究结果一致,Rbp4、Gpc3、C1qtnf3可能在颅缝早闭中具重要调控作用。杨娴娴 Jodie T Hatfield Susan J Hinze 穆雄铮 Peter J Anderson Barry C Powell 2012组织工程与重建外科杂志2012,8,5:3

10Novel predictors of permanent pacemaker implantation following transcatheter aortic valve replacement显示文摘BACKGROUND Conduction and rhythm abnormalities requiring permanent pacemakers(PPM)are short-term complications following transcatheter aortic valve replacement(TAVR),and their clinical outcomes remain conflicting.Potential novel predictors of post-TAVR PPM,like QRS duration,QTc prolongation,and supraventricular arrhythmias,have been poorly studied.AIM To evaluate the effects of baseline nonspecific interventricular conduction delay and supraventricular arrhythmia on post-TAVR PPM requirement and determine the impact of PPM implantation on clinical outcomes.METHODS RESULTS Out of the 357 patients that met inclusion criteria,the mean age was 80 years,188(52.7%)were male,and 57(16%)had a PPM implantation.Baseline demographics,valve type,and cardiovascular risk factors were similar except for type II diabetes mellitus(DM),which was more prevalent in the PPM cohort(59.6%vs 40.7%;P=0.009).The PPM cohort had a significantly higher rate of pre-procedure right bundle branch block,prolonged QRS>120 ms,prolonged QTc>470 ms,and supraventricular arrhythmias.There was a consistently significant increase in the odds ratio(OR)of PPM implantation for every 20 ms increase in the QRS duration above 100 ms:QRS 101-120[OR:2.44;confidence intervals(CI):1.14-5.25;P=0.022],QRS 121-140(OR:3.25;CI:1.32-7.98;P=0.010),QRS 141-160(OR:6.98;CI:3.10-15.61;P<0.001).After model adjustment for baseline risk factors,the OR remained significant for type II DM(aOR:2.16;CI:1.18-3.94;P=0.012),QRS>120(aOR:2.18;CI:1.02-4.66;P=0.045)and marginally significant for supraventricular arrhythmias(aOR:1.82;CI:0.97-3.42;P=0.062).The PPM cohort had a higher adjusted OR of heart failure(HF)hospitalization(aOR:2.2;CI:1.1-4.3;P=0.022)and nonfatal myocardial infarction(MI)(aOR:3.9;CI:1.1-14;P=0.031)without any difference in mortality(aOR:1.1;CI:0.5-2.7;P=0.796)at one year.CONCLUSION Pre-TAVR type II DM and QRS duration>120,regardless of the presence of bundle branch blocks,are predictors of post-TAVR PPM.At 1-year post-TAVR,patients with PPM have higher odds of HF hospitalization and MI.Somto Nwaedozie Haibin Zhang Javad Najjar Mojarrab Param Sharma Paul Yeung Peter Umukoro Deepa Soodi Rachel Gabor Kelley Anderson Romel Garcia-Montilla 2023World Journal of Cardiology2023,15,11:2
