| 3 | Relationship 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 | 2014 | World Journal of Gastroenterology2014,20,45: | 9 |
| 4 | Dietary and metabolomic determinants of relapse in ulcerative colitis patients: A pilot prospective cohort study显示文摘AIM To identify demographic, clinical, metabolomic, and lifestyle related predictors of relapse in adult ulcerative colitis(UC) patients.METHODS In this prospective pilot study, UC patients in clinical remission were recruited and followed-up at 12 mo to assess a clinical relapse, or not. At baseline information on demographic and clinical parameters was collected. Serum and urine samples were collected for analysis of metabolomic assays using a combined direct infusion/liquid chromatography tandem mass spectrometry and nuclear magnetic resolution spectroscopy. Stool samples were also collected to measure fecal calprotectin(FCP). Dietary assessment was performed using a validated self-administered food frequency questionnaire. RESULTS Twenty patients were included(mean age: 42.7 ± 14.8 years, females: 55%). Seven patients(35%) experienced a clinical relapse during the follow-up period. While 6 patients(66.7%) with normal body weight developed a clinical relapse, 1 UC patient(9.1%) who was overweight/obese relapsed during the follow-up(P = 0.02). At baseline, poultry intake was significantly higher in patients who were still in remission during follow-up(0.9 oz vs 0.2 oz, P = 0.002). Five patients(71.4%) with FCP > 150 μg/g and 2 patients(15.4%) with normal FCP(≤ 150 μg/g) at baseline relapsed during the follow-up(P = 0.02). Interestingly, baseline urinary and serum metabolomic profiling of UC patients with or without clinical relapse within 12 mo showed a significant difference. The most important metabolites that were responsible for this discrimination were trans-aconitate, cystine and acetamide in urine, and 3-hydroxybutyrate, acetoacetate and acetone in serum. CONCLUSION A combination of baseline dietary intake, fecal calprotectin, and metabolomic factors are associated with risk of UC clinical relapse within 12 mo. | Ammar Hassanzadeh Keshtel iFloris F van den Brand Karen L Madsen Rupasri Mandal Rosica ValchevaKaren I Kroeker Beomsoo Han Rhonda C Bell Janis Cole Thomas Hoevers David S Wishart Richard N Fedorak Levinus A Dieleman | 2017 | World Journal of Gastroenterology2017,23,21: | 9 |
| 5 | TAT-Gap19通过抑制啮齿动物星形胶质细胞的连接蛋白43半通道发挥抗惊厥作用显示文摘越来越多的证据表明,星形胶质细胞连接蛋白43(Cx43)信号在癫痫中发挥至关重要的作用。但是,由于通过实验方法鉴别Cx43间隙连接通道(GJCs)和半通道(HCs)的技术尚不成熟,导致目前尚无法确定哪个通道在癫痫的发生中发挥更重要的作用。因此,本研究观察TAT-Gap19(Cx模拟肽)是否通过抑制Cx43半通道而非Cx43间隙连接通道影响实验诱导的啮齿动物癫痫发作。急性海马切片小鼠染料摄取实验表明,星形胶质Cx43半通道响应化学惊厥毛果芸香碱的作用而开放,并且可被TAT-Gap19抑制。体内实验中,毛果芸香碱诱导的癫痫发作及相伴随的D-丝氨酸微透析液的增长水平被Cx43半通道的抑制所抑制。此外,TAT-Gap19的抗惊厥作用被外源性D-丝氨酸给药逆转,这表明,抑制Cx43半通道可以通过降低细胞外D-丝氨酸水平来防止癫痫发作。抑制Cx43半通道的抗惊厥特性在电癫痫小鼠模型(如急性6 Hz难治性癫痫发作模型和慢性6 Hz角膜点燃模型)中得到了进一步的证实。总而言之,这些结果表明,Cx43半通道在癫痫发作中可以起到一定作用,并且有成为癫痫治疗中新型用药靶点的潜力。 | Walrave L Pierre A Albertini G Aourz N De Bundel D Van Eeckhaut A Vinken M Giaume C Leybaert L Smolders I 聂昊 | 2018 | 神经损伤与功能重建2018,13,6: | 5 |

| 10 | 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) 无 | 2017 | 皮肤性病诊疗学杂志2017,24,5: | 3 |
