现代医学教育创新的思考与对策

随着科技进步的加速,现代医学教育创新势在必行.本文针对这一现状,阐述了现代医学教育创新的内涵,分析了现代医学教育创新面临的问题,探讨了医学院校如何进行创新教育,介绍了山西医科大学对实施现代医学教育创新的一些具体措施.     

后囊连续环形撕囊在儿童人工晶体植入术的应用

后发障是儿童白内障最常见的并发症，是导致术后视力下降的主要原因，故降低后发障的发生率对提高术后视力及减少弱视的发生非常重要，以往文献报道大多是术后行ND-YAG激光后囊切开术来治疗后发障。笔者近年对儿童白内障采用白内障摘除人工晶体植入联合后囊连续环形撕囊术预防人工晶体术后后囊混浊，效果肯定，报告如下。     

低调做人，踏实做事——访上海麦迪逊医疗器械有限公司总经理赵在玉先生

从2004年下半年到2005年上半年,世界超声联合会以及中华医学会超声学会共同举办了5次较大规模的超声学术研讨会,上海麦迪逊医疗器械有限公司作为唯一的赞助商承担了全部研讨会的组织运行工作,投入了很大的人力、财力、物力,但是在研讨会上却没有看到他们任何与商业有关的活动.上海麦迪逊的这种作法引起了我的注意,于是我找来麦迪逊公司的简单资料:     

Coping with economic crisis: policy development in China and India

This paper explores health policy options in response to economiccrises in developing countries. The paper is based upon thepremise that policy is best pursued within a broad understandingof the determinants of health of populations. To provide anempirical base for analysis, the health status and health caresystems of China and India are compared. A conceptual frameworkon the determinants of the health status of populations is thendeveloped, incorporating both the performance of health caresystems and non-medical factors which influence health. Usingthe China and India experiences, the paper reviews the strengthsand weaknesses of traditional tools used in the analysis ofhealth policy. Significant policy change, it is argued, is bestimplemented through structural change of several health caresystem components simultaneously. Health policy analysis, itis further argued, must consider the broader political economyof the society. Moreover, there remain many imperfectly understoodsociocultural aspects of behaviour which enable some familiesto produce good health despite economic constraints. The paperconcludes that economic crisis presents an opportunity for astructural review of a society's health systems. Health policyoptions in response to economic crisis cannot be confined tothe health care sector. Rather, health policy should be viewedas only one, perhaps important, element of a package of socioeconomicpolicy options. Critical to policy choices are reliable informationon the condition of the poor and high political priority tominimize the adverse impact of economic crisis on the health,nutrition and social welfare of disadvantaged groups.     

人肿瘤特异抗原MAGE-3基因疫苗的构建和表达

目的：克隆肿瘤特异性共享抗原mage-3基因，制备基于α－病毒复制酶的高效黑色素瘤特异性基因疫苗。方法：用RT-PCR方法从黑色素瘤细胞系LB373中制备mage-3基因，以含α－病毒复制酶的哺乳细胞高效表达质粒pSMART2a为载体，构建重组DNA疫苗。重组子用载体中的T7和T3启动子序列为测序引物进行自动测序。再将鉴定过的重组质粒用脂质体法转化293细胞，用免疫印迹法和免疫组化法鉴定转化细胞中mage-3蛋白的表达。结果：正确构建了mage-3/pSMART2a重组质粒，并且在转化此质粒的293细胞中检测出了mage-3蛋白的表达。结论：此重组mage-3/pSMART2a质粒可以作为肿瘤特异的DNA疫苗，可进行下一步的肿瘤动物模型的疫苗接种及相关免疫学效应研究。     

16层螺旋CT对肋骨骨折的诊断价值

随着工业化进程的加速及交通事故的增加,胸部创伤日渐增多。国内报道在45 569例创伤中,胸部创伤占1·47%[1],其中肋骨骨折非常常见。随着螺旋CT检查临床应用日趋广泛,其高敏性、快速成像的特性及强大的后处理功能越来越在肋骨骨折中显现重要作用。本文对53例肋骨骨折患者的16层     

护理工作量测量的影响因素

对影响护理工作量测量的护士因素、患者因素及环境等诸多因素进行综述。提出管理工作者需根据目前护理人力资源现状和配置标准进行分析、论证，明确界定护理工作的性质和内容，制定适合我国国情的护理工作量测量工具，以合理分配护理人力资源，使有限的护理资源满足广大患者的需要，从而提高社会效益和经济效益。     

继发性肝癌的外科治疗

目的探讨继发性肝癌的手术适应证和方法。方法对52例继发性肝癌的临床病例资料进行回顾性分析。结果分别采用了左半肝切除、右半肝切除、左外叶切除、右前叶切除、右后叶切除和肝楔形切除术。术后1、3、5年的生存率分别为28.3%、19.4%和11.9%。结论对适合手术的继发性肝癌,行肝切除术可以获得满意的效果。
