全英语病理学教学的四点体会

在初步开展了全英病理学教学后，我们认为提高教师的日常英语口语表达能力；用英语作为载体，重新构建教师的医学知识体系；要求学生课前认真预习；授课时尽可能多地采用图片，对采用全英语讲好病理学课大有裨益。     

医学微生物学"项目-导师制"实验教学改革初探

目的:探讨"项目-导师制"实验教学改革效果及其在医学微生物学实验教学中应用价值.方法:采用"项目-导师制"法对2001级学生进行医学微生物学实验教学,以无记名问卷调查和专家评议方式了解实验教学效果,以现场操作了解学生实验技能,以相对标准化试卷综合测试学生成绩,并与2000级学生医学微生物学实验教学效果、实验技能、考试成绩进行回顾性和对比分析.结果:2001级和2000级学生实验教学效果不满意、满意、很满意率分别为0%(0/180)、25.00%(45/180)、75.00%(135/180)和55.38%(72/130)、34.62%(45/130)、10.00%(13/130),差异有显著性(P＜0.01).实验技能考核及格、良好、优秀率分别为0%(0/180)、22.22%(40/180)、77.78%(140/180)和56.92%(74/130)、35.38%(46/130)、7.69%(10/130),差异有显著性(P＜0.01).综合考试成绩不及格、及格、良好、优秀率分别为0%(0/180)、17.78%(32/180)、47.22%(85/180)、35.00%(63/180)和154%(2/130)、38.46%(50/130)、52.31%(68/130)、7.69%(10/130),差异有显著性(P＜0.01).结论:"项目-导师制"实验教学是一种新型实验教学模式,可显著增强实验教学效果,帮助学生快速掌握实验技能,提高学生综合考试成绩,克服传统实验教学存在的一些弊端,具有应用推广价值.     

Comparing orthodontic undergraduate student satisfaction with teaching in Leeds,UK and Marburg,Germany

A questionnaire was used to compare undergraduate student satisfaction with orthodontic teaching in two units; one in Leeds, UK, the other in Marburg, Germany. Whilst the methods of teaching differed between the units, the aim was to highlight aspects of both courses which students might wish to see improved. Statistical analysis suggested that students appreciate clarity of course structure and means of assessment and that use of a course manual is helpful in achieving this. Recommended texts to back-up course work are also appreciated whilst students from both locations, want to see more patients. Alternatives, such as patient case folders, computer-assisted learning packages and use of videos showing treatment progression, seem to be acceptable alternatives should there be difficulty in supplying “real” patients. The relevance of laboratory courses needs to be reviewed. Overall, the use of student questionnaires is seen as a useful tool in monitoring standards of teaching.     

Candidaemia: a 10-year study in an Indian teaching hospital

Retrospective evaluation of candidaemia patients was performed in an Indian teaching hospital over a 10-year period. The incidence of patients with candidaemia increased eleven-fold in the second half of the study period (55 patients) compared with the first half (5 patients). Haematological malignancies (11 patients), neonatal septicaemia (9), cardiac abnormalities and cardiac surgery (9) were the commonest underlying diseases in these patients. Candida albicans (50%), C. guilliermondii (17%), C. tropicalis (15%) and C. parapsilosis (8%) were the most common fungal pathogens isolated from blood culture. Therapy with two or more antibiotics (92%), corticosteroid administration (25%), intravascular catheter use for over 24 h (78%) and neutropenia (48%) were the accountable predisposing factors. Prolonged hospitalization (mean average 22.2 days as compared with 11.2 days in other patients) was an added risk factor in these patients.     

House officers in general medicine: their perception of educational value of rotation components

Summary: As curriculum planners in general medicine residency training programmes we were concerned about house officers' anecdotal reports that hospital work requirements often overshadow individual learning goals. After each of five rotations, we asked residents to identify the educational 'usefulness' of certain rotation components which can be included in three categories; team members, work-related activities and educational events. Of 165 surveys distributed, 127 (77%) were returned. Data were analysed by residency year and by all years combined. The mean overall perception of learning was 3.9 out of a possible 5 points suggesting that residents do find some learning value. Results suggest that different residency years vary as to the significance of specific educational components. The importance of faculty/resident relationships to residents' perceptions of learning value was highlighted in particular.     

低剂量混配农药对家兔血浆谷胱甘肽过氧化物酶和一氧化氮的影响

目的 探讨低剂量混配农药对家兔脂质过氧化及一氧化氮（NO）浓度的影响及意义。方法 将家兔随机分为6个混配农药染毒组、1个丙溴磷染毒组和1个对照组，于不同的时间测定各组血清胆碱酯酶（ChE)活力、谷胱甘肽过氧化物酶（GSH-Px)活力及一氧化氮（NO）浓度。结果 除较高剂量混配农药组外，其余各组染毒后的ChE活力均大于对照组实验前平均值的70%。随着染毒时间的延长农药混配组血浆GSH-Px活力高于或显著高于同时间的单剂量组和对照组，而血浆NO的浓度则呈降低趋势。结论 低剂量含有机磷的混配农药在导致ChE活力降低之前即可造成脂质过氧化增强和NO浓度的降低。     

University and Community Hospital Medical Student Emergency Medicine Clerkship Experiences

Objective : To determine whether there is a significant difference between educational opportunities for fourth-year medical students rotating at a university hospital (UH) compared with several community hospitals (CHs) during a mandatory emergency medicine (EM) clerkship.
Methods : A self-reported clinical tool was completed in real time by each student rotating for 2 weeks at the UH and 2 weeks at 1 of 4 CHs (3 affiliated and 1 unaffiliated). Students are required to document the number of patients seen and the number of procedures performed on each of 20 six-hour shifts. They rated the EM attending clinical teaching by site using a 5-point scale at the end of the clerkship.
Results : Most (95%) of the 87 students in the 7 clerkship blocks of the 1996–97 academic year rotated at the UH and a CH. Most (71%) students rated both the UH and the CH for the quality of teaching by attendings. There was a significant difference in the mean number of patients evaluated/shift (2.2 ± 0.10 vs 2.8 ± 0.10, UH vs CH; p < 0.001) and the mean number of procedures performed/shift (0.36 ± 0.04 vs 0.56 ± 0.05, UH vs CH; p < 0.001). Attending clinical teaching scores were significantly higher (p = 0.03) at the CHs.
Conclusions : The educational opportunities for students in an EM clerkship to evaluate patients and perform procedures were significantly greater at the community hospitals. Inclusion of community hospital settings in a medical student EM clerkship may optimize the clinical experience.
