Evidence-based Medicine

Summary:  Evidence-based medicine (EBM) has become a watchword for "the new" medical practice in the new century. Whether it represents a paradigm shift or simply a codification of the scientific method in medicine will be debated for years to come. Regardless of the place of EBM in medicine, this "movement" has served an important role in moving physician practice into the realm of becoming more scientific (albeit empirical) and transparent. There are still many problems to be addressed in the global application of the best evidence for medical practice. These include low-quality studies, delays in implementation of clear-cut improvements, outright fraud and deceit, and wariness on the part of physicians to change their practice. By working to understand the underpinnings of EBM (basic statistical concepts and critical thinking) we can advance the practice of medicine along the moral high road of science.     

Concerns for medical radiation programs in Australian universities

The Australian higher education system is in a state of great change. The Federal education minister, Dr Brendan Nelson, has indicated that he intends to continue introducing far-reaching reforms that will impact significantly on how universities conduct teaching and research. The future allocation of government funding for university programs, including those in medical radiation, will have a significant effect on how those programs are delivered and could even determine whether programs remain viable. There will be a financial imperative for academic departments to strengthen research activity and to obtain funding from non-government sources, such as full-fee paying students, in order to generate enough income to cover program delivery. Medical radiation education in Australia is also facing many other challenges. Some of these are longstanding, such as the high cost of medical radiation program delivery, poor levels of research activity and difficulty in recruiting and retaining academic staff. Other problems have arisen recently, such as increased competition for students and a critical shortage of available training placements in clinical practice. The aim of this paper is to raise and explore these issues from a university perspective.     

民族生留学生考试不及格原因与对策调查

为了解临床医学专业留学生和民族生较为严重的功课不及格的原因并寻求相应的对策，课题组于2005年12月进行了学生问卷调查，2006年4月对教师进行了半结构式访谈调查和访谈发现，学生的汉语水平和原有的学习基础、学习生活习惯、对学校教学管理制度和管理系统的熟悉程度、自学时间和学习努力程度、学校学院教师对待他们方式等是主要的影响因素；根据调查与访谈，课题组针对影响因素归纳出了相应的对策，     

Proximal load transfer with a stemless uncemented femoral implant

Bone stock preservation is crucial when performing total hip replacement in young patients. The aim is to save good bone stock for a possible revision procedure. Furthermore, there is an increasing demand from young and active patients to receive a new joint which allows a normal or nearly normal life style. With this in mind, we began, in 1993, to develop a new femoral implant. The purpose of this ultra-short stem was a physiologic strain distribution on the proximal femur with a proximal load transfer from the implant to the femoral bone. Main features were an almost complete absence of the diaphyseal portion of the stem, a well defined lateral flare with load transfer on the lateral column of the femur, and a very high femoral neck cut. These innovations resulted in a conservative implant on both the bone stock and the soft tissues. This implant, in the first years, was recommended only for young and active patients. Over the last thirteen years, this project has undergone several modifications but the basic principles of the implant have remained the same. In the present review, we present the rationale, the surgical technique and the clinical and experimental results so far obtained with this implant.     

试论加强国际合作与促进我国医学伦理学教育的发展

原北京医科大学(现为北京大学医学部)从20世纪90年代初开始,积极寻求与美国中华医学基金会的合作以促进医学伦理学的学科发展和国际化水平的提高。十几年来,北京大学医学部作为基地和依托极大地支持和引领了我国医学伦理学的教学改革与发展,增强了相关人员的医学伦理意识以及医学伦理学理论对实践的指导作用,促进了伦理学知识和能力的培训,提升了我国生物医学科研伦理的实力,奠定了医学伦理学继续教育的基础,使医学伦理学实现了系统性和跨越式的发展。     

医科院校学生心理危机管理浅探

结合医科院校学生心理危机管理的实践，阐述大学生心理危机的内涵、类型、特征及心理危机管理的特性，并从建立预警系统、增设心理委员、危机处理的专业化及危机干预策略等方面探讨在医科院校加强学生心理危机管理的对策。     

从天价医药费事件折射出当前我国医疗机构存在的问题

目前，我国许多医院的医疗卫生工作人员在为患者进行医疗卫生服务的过程中，为了医院和个人的经济利益，存在着过度医疗消费现象。最典型的是哈尔滨医科大学第二附属医院发生的天价医药费事件。导致这种现象出现的原因是由于法律的不健全、制度的不完善等而导致的监督力度不够，加之有些医务工作者在经济利益的驱使下使自己的职业道德滑坡，从而导致了老百姓看病贵现象的出现。     

20世纪后半叶美国高等医学教育改革历程

美国现代高等医学教育模式的确立是以20世纪初Flexner报告发表为开端的。第二次世界大战前，现代高等医学教育体系已基本完善，并经历了二战的考验。二战后，随着社会和医学发展，美国高等医学教育一直在进行着改革。按照时间顺序在50年代、60年代以及70、80年代进行了改革。分析历次改革的背景、主要内容及改革的特点特别对指导20世纪80年代后医学教育改革的纲领性文件——GPEP报告进行详细阐述，包括GPEP报告的内容、作用以及与Flexner报告的对比分析。通过回顾与分析，对美国医学教育改革历程中的成功经验和不足之处进行梳理，为我国正在进行的高等医学教育改革提供借鉴与参考。
