台州市功能性消化不良的流行病学现状调查及影响因素分析

目的 探讨台州市功能性消化不良的流行病学现状及影响因素。方法 回顾性选取2020年1月至2022年2月浙江省台州医院收治的功能性消化不良患者200例，统计患者的一般资料，分析该病的流行病学现状，对功能性消化不良的影响因素进行单因素分析，然后将差异有统计学意义的因素再进一步纳入多因素Logistic回归分析。结果 200例功能性消化不良患者中，女性发病率高于男性；30~60岁年龄段群体，患病率最高；存在暴饮暴食、喜食烫食、挑食、多食酸制品、未准时进食、常食宵夜、睡眠时间<6h、有药物过敏史、有功能性消化不良家族史、存在便秘情况者的患病率均高于未存在以上情况者，差异均有统计学意义（P<0.05）。多因素Logistic回归分析显示，性别、年龄、暴饮暴食、喜食烫食、挑食、多食酸制品、未准时进食、宵夜摄取情况、每天睡眠时间、药物过敏史、家族史、便秘是该病患病率升高的主要影响因素。结论 性别、年龄、暴饮暴食、喜食烫食、挑食、酸制品、未准时进食情况、宵夜摄取情况、每天睡眠时间、药物过敏史、家族史、便秘是功能性消化不良的主要影响因素。     

Event-related potential changes due to early-onset Parkinson’s disease in parkin (PARK2) gene mutation carriers and non-carriers

ObjectiveTo investigate cognitive functions in non-demented patients with early-onset Parkinson's disease (PD), and to compare PARK2 gene mutation carriers and non-carriers by means of event-related brain potentials (ERPs).MethodsThe participants comprised patients with early-onset PD (EOPD) and healthy controls (HC). Patients with EOPD were divided into two groups as carriers of known pathogenic variants of PARK2 gene (EOPD-PC) and non-carriers of genes involved in familial PD (EOPD-NC). ERP data were collected during auditory oddball and visual continuous performance test (CPT).ResultsBoth EOPD groups (EOPD-PC and EOPD-NC) displayed reduced and delayed P3 in response to oddball target and CPT NoGo. CPT Go P3 was reduced in EOPD-NC but not in EOPD-PC. Oddball target N1 was reduced and P2 was enhanced in both EOPD-PC and EOPD-NC. In both cognitive tasks, RTs were prolonged and accuracy was lower in EOPD-PC and EOPD-NC.ConclusionsWe found several EOPD-related neurophysiologic changes, implying impairments in cognitive functions. Pairwise comparisons between EOPD-PC and EOPD-NC revealed no significant ERP marker.SignificanceIn this study, the confounding effect of normative aging was somewhat excluded compared with many previous studies. In contrast with the many oddball studies in non-demented PD, we clearly observed reduced and prolonged P3 in early-onset PD. Our NoGo P3 findings also contribute to the limited ERP research concerning response inhibition.     

Preparing IR for COVID-19: The Singapore Experience

This paper describes country-wide special measures undertaken for interventional radiology staff during the current coronavirus disease 2019 (COVID-19) pandemic. Although each interventional radiology service around the world faces unique challenges, the principles outlined in this article will be useful when designing or strengthening individual practices and integrating them within wider hospital and national measures. Moving beyond the current outbreak, these measures will be useful for any future infectious diseases which are likely to arise.     

肝内胆管癌肝切除术后“教科书式结局”影响因素分析及预测模型建立

目的 分析肝内胆管癌（ICC）病人肝切除术后“教科书式结局”（TO）的影响因素，构建预测TO评分模型。方法 回顾性分析2011年1月至2017年1月东南大学附属中大医院和中国人民解放军东部战区总医院八一医院收治的261例行肝切除术的ICC病人临床病理资料，分析影响TO的独立危险因素，根据危险因素的权重构建预测TO的评分模型。结果 261例ICC病人中，67例（25.7%）术后发生TO。年龄、肝硬化、手术时间和T分期［第8版美国癌症联合委员会（AJCC）癌症分期］为术后TO的独立预测因素。依此4项因素构建的评分模型显示了较好的预测准确性，最佳截断值为-1.9分，其敏感度为67.2%，特异度为62.9%。一致性检验显示其预测概率和实际发生概率有着较好的一致性（χ2=1.350，P=0.853）。结论 基于年龄、肝硬化、手术时间、T分期4个因素建立的评分模型可较准确地预测ICC病人术后TO的可能性，即手术时间短、无肝硬化、肿瘤直径<5 cm的年轻ICC病人肝切除后获得TO的可能性更大。     

电针“足三里”穴对脾气虚大鼠小肠黏膜转运体SGLT1及GLUT2表达的影响

目的:观察电针双侧"足三里"穴对脾气虚模型大鼠小肠黏膜上皮组织内的钠依赖葡萄糖转运体(SGLT1),葡萄糖运载蛋白2(GLUT2)的基因及蛋白表达的影响。方法:将40只SD雄性大鼠随机分为正常组、脾气虚组、足三里组、非经非穴组,每组10只。所有大鼠均在SPF级动物实验中心饲养。除正常组外,其余3组均采用劳倦过度和不规则饮食复合法建立脾气虚证的大鼠模型。造模成功之后,对足三里组、非经非穴组大鼠分别进行电针"足三里"穴、非经非穴点干预处理7天。采用HE染色方法观察各组大鼠小肠黏膜组织形态变化;采用荧光定量PCR法检测大鼠小肠黏膜上皮的SGLT1和GLUT2的mRNA表达水平;采用蛋白质免疫印迹法(WB)检测大鼠小肠黏膜上皮组织内的SGLT1和GLUT2的蛋白含量变化。结果:脾气虚组大鼠小肠黏膜组织部分损伤,足三里组的小肠黏膜组织有一定程度的恢复;脾气虚组和非经非穴组大鼠小肠黏膜组织内的SGLT1和GLUT2蛋白和基因表达水平均明显低于正常组(P 0. 05);足三里组大鼠小肠黏膜组织内的SGLT1和GLUT2蛋白和基因表达水平相比于脾气虚组有所升高(P 0. 05),非经非穴组未见显著性差异(P 0. 05)。结论:电针"足三里"穴可以调节脾气虚大鼠小肠黏膜上皮组织内的SGLT1和GLUT2基因及蛋白的异常表达,参与小肠对葡萄糖的吸收作用进而改善脾气虚证。
