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。     

Undergraduate psychiatry teaching in Ethiopia

Many epidemiological studies have shown the magnitude and seriousness of mental disorders in developing countries. However, mental health care remains unsatisfactory owing to lack of skilled manpower and many other social and medical priorities. General practitioners and other health personnel can significantly help in extending mental health care provided they receive adequate training during their medical curriculum. With this aim, the Department of Psychiatry at Addis Ababa University runs a 6-week full-time course for undergraduate medical students. Its chief objectives, teaching methods, achievements and shortcomings are discussed in the paper.

静脉输液瓶（袋）的排列排序方法

为杜绝输液过程中液体少输或者多输及错输的情况发生，经过2001-2007年5年总结出了一套静脉输液瓶的排列排序方法，应用此方法，减少了差错事故的发生，同时也减轻了护士来回加注输液的时间，提高了护理质量及工作效率。这种排列排序方法主要是用26个英文字母进行排列和排序。     

Basic sciences in problem-based learning and conventional curricula: students' attitudes

The purpose of this study was to compare the attitudes toward basic sciences of students in a preclinical problem-based curriculum and a conventional lecture-based curriculum at the end of their second year of medical school. The results showed that the PBL class had more positive attitudes toward basic sciences than students in the conventional class. These results may reflect a learning environment where students meet many scientist role models as teachers and where basic science is learnt in the context of clinical problems.     

Ultrastructural synaptology of Clarke's column

Summary An electron microscopic analysis of the synapses in Clarke's column of the cat, using fresh short term degeneration, long term degeneration for detection of the persisting elements, and a newly devised two-step degeneration technique using fresh short term degeneration for further analysis of the persisting synaptic elements in chronic degeneration cases. — Three kinds of synaptic terminals can be identified in the lower part (L₃ segmental level) of Clarke's column: (1) very large (so-called giant) axon terminals with spheric vesicles of primary muscle afferents establishing multiple (climbing-type) contacts mainly with the large dorsal spinocerebellar tract neurons; (2) small bouton-type terminals having spheric synaptic vesicles and originating mainly from spinal interneurons, localized below L₄ in the lumbar enlargement and contacting small distal dendrites and cell bodies of small cells; (3) two types of nerve terminals, originating from local neurons, and characterized by flattened vesicles. One type of (3) contacts mainly the large Clarke neurons directly, whereas the other establishes axo-axonic synapses with the giant terminals (1) of primary muscle affer ents. The possible functional significance of these findings is discussed.

The three-dimensional microvascular arrangement around rat dorsal hairs as revealed by scanning electron microscopy

The three-dimensional microvascular arrangement around the dorsal hairs in vascular corrosion casts of adult Wistar rats was studied by scanning electron microscopy. Each anagen dorsal hair was surrounded by a basket-like capillary network, which was supplied by the branches of the subcutaneous artery and drained into the veins continuous with the subcutaneous vein. The capillary network surrounding the anagen dorsal hair was denser at its lower part, and became more sparse at its upper part. Transmission electron microscopy showed that the capillaries around the hair bulb possessed fenestrations. Our findings indicate that the microvascular arrangement around the anagen dorsal hair is so organized as to supply the hair bulb, which is the most important area for hair growth, with abundant blood. This study was presented at the 24th Annual Meeting of the Clinical Electron Microscopy Society of Japan, Okayama, September 17–19, 1992.
