3Relationship between the exocrine and endocrine pancreas after acute pancreatitis显示文摘AIM:To determine the prevalence and time course of pancreatic exocrine insufficiency in individuals with newly diagnosed prediabetes or diabetes mellitus after acute pancreatitis.METHODS:Relevant literature cited in three major biomedical journal databases(EMBASE,MEDLINE,and Scopus)was reviewed independently by two authors.There were no language constraints but the search was limited to human studies.Studies included were cohort studies of adult patients who were discharged after an attack of acute pancreatitis.Patients were excluded if they were under 18 years of age or had a previous diagnosis of prediabetes or diabetes mellitus,pancreatic exocrine insufficiency,or chronic pancreatitis.The main outcome measure was the prevalence of concomitant pancreatic exocrine insufficiency in patients who were diagnosed with prediabetes and diabetes mellitus after an attack of acute pancreatitis.Subgroup analysis was conducted for patients who were diagnosed with prediabetes only and those who were diagnosed withdiabetes mellitus only.Subgroup analysis looking at the time course of concomitant pancreatic exocrine and endocrine insufficiency was also conducted.Pooled prevalence and corresponding 95%confidence intervals were calculated for all outcome measures and P-values<0.05 were deemed statistically significant.RESULTS:Eight clinical studies comprising of 234patients met all eligibility criteria.The pooled prevalence of newly diagnosed prediabetes or diabetes in individuals after acute pancreatitis was 43%(95%CI:30%-56%).The pooled prevalence of pancreatic exocrine insufficiency in individuals after acute pancreatitis was 29%(95%CI:19%-39%).The prevalence of concomitant pancreatic exocrine insufficiency in individuals with newly diagnosed prediabetes or diabetes was 40%(95%CI:25%-55%).The prevalence of concomitant pancreatic exocrine insufficiency among individuals with prediabetes alone and diabetes mellitus alone was 41%(95%CI:12%-75%)and 39%(95%CI:28%-51%),respectively.Further analysis showed that the prevalence of concomitant pancreatic exocrine insufficiency in individuals with prediabetes or diabetes decreases over time after an attack of acute pancreatitis.CONCLUSION:Pancreatic exocrine insufficiency occurs in 40%of individuals with newly diagnosed prediabetes or diabetes mellitus after acute pancreatitis.Further studies are needed to investigate the pathogenesis of diabetes in this setting.Stephanie L M Das James I C Kennedy Rinki Murphy Anthony R J Phillips John A Windsor Maxim S Petrov 2014World Journal of Gastroenterology2014,20,45:9
4Orally administered extract from Prunella vulgaris attenuates spontaneous colitis in mdr1a^(-/-) mice显示文摘AIM: To investigate the ability of a Prunella vulgaris(P. vulgaris) ethanolic extract to attenuate spontaneous typhlocolitis in mdr1a-/- mice. METHODS: Vehicle(5% ethanol) or P. vulgaris ethanolic extract(2.4 mg/d) were administered daily by oral gavage to mdr1a-/- or wild type FVBWT mice from 6 wk of age up to 20 wk of age. Clinical signs of disease were noted by monitoring weight loss. Mice experiencingweight loss in excess of 15% were removed from the study. At the time mice were removed from the study, blood and colon tissue were collected for analyses that included histological evaluation of lesions, inflammatory cytokine levels, and myeloperoxidase activity. RESULTS: Administration of P. vulgaris extracts to mdr1a-/- mice delayed onset of colitis and reduced severity of mucosal inflammation when compared to vehicle-treated mdr1a-/- mice. Oral administration of the P. vulgaris extract resulted in reduced(P < 0.05) serum levels of IL-10(4.6 ± 2 vs 19.4 ± 4), CXCL9(1319.0 ± 277 vs 3901.0 ± 858), and TNFα(9.9 ± 3 vs 14.8 ± 1) as well as reduced gene expression by more than two-fold for Ccl2, Ccl20, Cxcl1, Cxcl9, IL-1 α, Mmp10, VCAM-1, ICAM, IL-2, and TNFα in the colonic mucosa of mdr1a-/- mice compared to vehicle-treated mdr1a-/-mice. Histologically, several microscopic parameters were reduced(P < 0.05) in P. vulgaris-treated mdr1a-/-mice, as was myeloperoxidase activity in the colon(2.49 ± 0.16 vs 3.36 ± 0.06, P < 0.05). The numbers of CD4+ T cells(2031.9 ± 412.1 vs 5054.5 ± 809.5) and germinal center B cells(2749.6 ± 473.7 vs 4934.0 ± 645.9) observed in the cecal tonsils of P. vulgaris-treated mdr1a-/- were significantly reduced(P < 0.05) from vehicle-treated mdr1a-/- mice. Vehicle-treated mdr1a-/- mice were found to produce serum antibodies to antigens derived from members of the intestinal microbiota, indicative of severe colitis and a loss of adaptive tolerance to the members of the microbiota. These serum antibodies were greatly reduced or absent in P. vulgaris-treated mdr1a-/- mice. CONCLUSION: The anti-inflammatory activity of P. vulgaris ethanolic extract effectively attenuated the severity of intestinal inflammation in mdr1a-/- mice.Kelley MK Haarberg Meghan J Wymore Brand Anne-Marie C Overstreet Catherine C Hauck Patricia A Murphy Jesse M Hostetter Amanda E Ramer-Tait Michael J Wannemuehler 2015World Journal of Gastrointestinal Pharmacology and Therapeutics2015,6,4:8
5簇毛麦抗白粉病基因的RAPD及RFLP标记显示文摘分析了来自前苏联簇毛麦及其抗病衍生系的抗白粉病基因对不同生理小种的抗性反应。用 120 个随机引物对 6D/6V 代换系 Pm930640 进行 RAPD 分析,检测到 5 个引物 OPAN03、OPAI01、OPAL03、OPAD07 和 OPAG15,分别在大约 1 700、700、750、480 和 580 bp 处有区别于小麦亲本的多态性条带。对 Chancellor×Pm930640 F2群体进行 OPAN03、OPAI01 和 OPAL03 等 3 个 RAPD 标记与抗白粉病基因的连锁分析,表明这些标记同簇毛麦的抗白粉病基因是连锁的。对大部分分别含有 Pm1-Pm20 的已知抗病基因、含有簇毛麦抗病基因及其相关亲本的 29 个小麦品系进行RAPD标记分析。结果表明,这些标记不仅可以鉴定簇毛麦的抗病基因,而且可以判断其遗传背景。OPAL03750仅出现在含有前苏联簇毛麦 6VS 染色体的抗病材料中,可作为区别于 Pm21 的分子标记。RFLP 标记的结果也表明两个不同簇毛麦的 6VS 染色体有明显的多态性。李辉 陈孝 施爱农 孔凡晶 Leath S Murphy J P 贾旭 2005中国农业科学2005,38,3:7
6Risk 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

8Have 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
9系统性药物治疗儿童银屑病的安全性显示文摘银屑病是一种常见的慢性炎症性皮肤病。成年人的发病率为2%~3%,其中大约有三分之一的患者在18岁之前发病。在儿童期,该病的发病率呈线性增长。从1970年至2000年,儿童银屑病的发病率增加了一倍多。尽管对许多轻度银屑病患儿而言,局部治疗已足够,但对更多可能影响生活质量的重度或顽固性的银屑病患儿,则往往需要系统性治疗。bronckers imgj seyger mmb west dp lara-corrales i tollefson m tom wl hogeling m belazarian l zachariae c mahé e siegfried e philipp s szalai z vleugels ra holland k murphy r baselga e cordoro k lambert j alexopoulos a mrowietz u kievit w paller as 邓婕(编译) 张锡宝(审校) 2017皮肤性病诊疗学杂志2017,24,5:3
10C-reactive protein and radiographic findings of lower respiratory tract infection in infants显示文摘AIM To evaluate the association between C-reactive protein(CRP) and radiological evidence of lower respiratory tract infection(LRTI) in infants.METHODS All patients aged less than 4 years who presented with suspected lower respiratory tract infection,who received a peri-presentation chest radiograph and CRP blood measurement over an 18-mo period were included in the study.Age,gender,source of referral,CRP,white cell count,neutrophil count along with the patients' symptoms and radiologist's report were recorded.RESULTS Three hundred and eleven patients met the inclusioncriteria.Abnormal chest radiographs were more common in patients with elevated CRP levels(P < 0.01).Radiologic signs of LRTI were identified in 73.7% of chest radiographs when a patient had a CRP level between 50-99 mg/L.CRP levels were a better predictor of positive chest radiograph findings for those aged greater than I year compared to those 1 year or less.CONCLUSION CRP may be used in patients with suspected LRTI diagnosis to select those who are likely to have positive findings on chest radiograph,thus reducing unnecessary chest radiographs.Maria Twomey Hannah Fleming Fiachra Moloney Kevin P Murphy Lee Crush Siobhan B O’Neill Oisin Flanagan Karl James Conor Bogue Owen J O’Connor Michael M Maher 2017World Journal of Radiology2017,9,4:2
