医学文献检索课中期刊论文分类标引的教学

针对当前的医学文献检索课中忽略期刊论文分类标引教学的问题,总结了几点教学实践,分别从期刊论文分类标引准确的重要性、期刊论文分类标引的步骤及原则、医学期刊论文分类标引的注意事项几个方面进行阐述.     

《中华医学图书馆杂志》作者群的分析

对2001年《中华医学院图书馆杂志》的论文作者群进行了统计和分析。结果表明，该刊的作者女性居多，中年居多；作者的集中与离散程度比较明显；高学历、高职称，多成果人才云集，从个人角度看，研究还缺乏连续性和一定的深度，研究以个人为主，跨地域跨系统的群体合作研究明显水足。     

多普勒超声心动图食道调搏负荷试验对冠心病左室功能的评价

本文对１９例冠心病患者和１３例健康人进行了经食道心房调搏负荷多普勒超声心动图检查，旨在观察此法对冠心病患者的诊断价值。结果表明：（１）静息状态下多普勒超声心动图各项心功能指标二组之间无显著差异（Ｐ＞０．０５）；（２）在经食道心房调搏试验中左心室收缩指标Ｖｍａｘ、Ｖｍｅａｎ、ＶＴＩ、ＳＶ、ＣＯ等与对照组比较有显著差异（Ｐ＜０．００ｌ），以此几项指标进行二类判别分析，符合率达９３．７５％。结论认为经食道心房调搏负荷多普勒超声心动图是诊断冠心病的一项较敏感、无创易行的方法。     

《中国矫形外科杂志》被引分析研究

目的：分析《中国矫形外科杂志》被引情况，从文献引证角度了解该刊学术水平和期刊质量。方法：利用清华大学同方光盘股份有限公司研制开发的中国医院知识仓库期刊全文数据库中的数据，用定量分析的方法，对《中国矫形外科杂志》被引情况进行统计、分析和研究。结果：总被引2039篇次，被引频次逐年上升。2002年自引率1839％，单篇平均被引1．2次，影响因子0．293。结论：《中国矫形外科杂志》已形成自己的学术风格和专业特点，具有较高的被引率，是我国骨科领域的精品期刊之一。

解脲脲原体与自然流产关系的探讨

采用聚合酶链反应技术对３２例自然流产患者的宫颈粘液及其中２２例清宫组织进行解脲脲原体（ＵＵ）检测，并与３０例人工流产妇女比较。结果表明：自然流产与ＵＵ寄生于宫颈无关（Ｐ＞０．０５），与宫内感染ＵＵ明显相关（Ｐ＜０．０５）。     

1998～2004年《高原医学杂志》载文、著者和引文情况统计分析

Osteotomy around the knee: Assessment of quality,content and readability of online information

BackgroundAs knee osteotomy surgery becomes increasingly accessible, more patients may turn to the Internet for information. This study examined the source, quality, content and readability of online information regarding osteotomy around the knee.MethodsThe first 70 websites returned by the top four search engines were identified using the key words: “knee osteotomy” and “high tibial osteotomy.” The websites were categorised by type and assessed using the DISCERN score, Journal of the American Medical Association (JAMA) benchmark criteria and a novel Knee Osteotomy-Specific Score (KOSS). The presence of the Health On the Net (HON) code accreditation seal was noted. Readability of each website was assessed using eight readability formulae. The mean reading grade level (RGL) was compared to the 6th and 8th grade reading levels. The mean RGL of each category was also compared.ResultsOf the 45 unique websites analysed, the majority were Physician (33%) and Journal websites (31%). The mean DISCERN score was 36.7 (±8.9) which is classified as ‘poor.’ The mean JAMA benchmark criteria score was 2.04 (±1.5) and Physician websites were most likely to be scored zero. The mean KOSS was 15.4 (±5.7). The highest scoring website was a Commercial site but, overall, Journal category sites provided the best quality information. Websites that bore the HONcode seal obtained higher DISCERN, JAMA benchmark criteria and Knee Osteotomy - Specific Scores.The cumulative mean RGL was 13.2 (±2.2) which exceeded the 6th grade level by an average of 7.2 grade levels and the 8th grade level by an average of 5.2 grade levels. No website (0%) was written at or below either the 6th or the 8th grade reading levels. The mean Flesch Reading Ease Score of all websites was 41.13 (±14.7) which is classified as ‘difficult.’ Journal websites had the highest RGL.ConclusionThe information available online regarding osteotomy around the knee varies tremendously in quality and completeness. Physician sites predominate, but these were among the lowest scoring of all websites. Even where high quality information is available, it is set at too high a level to be easily understood.Level of evidenceSurvey of materials – Internet.
