目的探讨科学引文索引(SCI)对我国医学期刊的影响.方法检索SCI扩展版(SCI-E)数据库,得到2000至2009年各年被SCI-E收录的中国医学论文和其刊载期刊,对刊载这些论文的期刊的影响因子分布、变化进行分析.查阅2000至2008年度中国科学技术信息研究所发布的<中国科技论文统计与分析>(2009年数据还未公布),得到2000至2008年中国科技论文与引文数据库(CSTPCD)收录的论文数,比较SCI-E和CSTPCD收录论文的变化趋势.对一组动态(与时间相关)资料的分析,采用"定基比"(与1个固定时间2000年的数值比)和"环比"(后1年与前1年比).求平均速度时,采用几何均数(G),影响因子数的分布描述采用中位数.结果 2000年SCI-E收录期刊刊出我国医学论文3774篇,其后逐年上升,到2008年增加到16 714篇,增加了442.87%,较同期CSTPCD收录期刊刊出的我国医学论文增加百分比(281.33%)高出161.54个百分点.10年来,SCI期刊收录的中国医学论文的几何平均增长速度为20.87%,2000至2008年CSTPCD的几何平均增长速度为18.2l%.2000至2009年,发表我国医学论文的SCI收录的期刊,影响因子并没有上升,甚至有下降,中位影响因子逐年为1.866、2.073、2.390、2.702、2.409、2.496、2.380、2.218、2.280、2.331;在SCI收录期刊上发表的论文平均被引次数也只有5.87次,仅为国际被引次数平均值(10.57次)的一半;发表在影响因子＞5的SCI期刊上的医学研究论文一直低于20%,平均仅占16.38%.结论 l0年来,我国在SCI收录期刊发表的论文数量逐年上升,增加幅度明显高于CSTPCD,但其影响力有限.要区别对待SCI期刊,控制在影响因子＜3的SCI期刊上发表论文,要鼓励在影响因子＞5的SCI期刊上发表研究论文.

Objective This study was designed to investigate the influence of journals indexed by Science Citation Index(SCI)on Chinese medical journals. Method Articles on medicine written by Chinese and the journals that published these articles from 2000 to 2009 were searched using Science Citation Index Expanded(SCI-E)database,and the status and variation tendency of the impact factors(IF)of these journals were analyzed.Data of articles on medicine included Chinese Scientific and Technical Paper and Citations Data(CSTPCD)from 2000 to 2008 were searched(the data of 2009 have not been released).The included articles and the time-dependent changing profile were studied.These outcomes were evaluated as the fixed base relative or link relative when compared with the data of 2000 or those of last year,respectively.Geometric mean was used when mean increase was calculated and IF distribution was described with median.Result Totally 3774 articles from China were published by journals indexed by SCI-E in 2000,and the number of articles published by Chinese authors increased every year. In 2008,16 714 articles were indexed by SCI-E,442.87% higher than those of 2000.The increment was 161.54% higher than that of articles published in the journals indexed by CSTPCD(281.33%)during the same period.From 2000 to 2009,the geometric mean of increase in the number of published articles from China in journals indexed by SCI-E was 20.87% but it was 18.21% in CSTPCD.From 2000 to 2009,the median of IF of SCI-E indexed journals that published Chinese medical articles was 1.866,2.073,2.390,2.702,2.409,2.496,2.380,2.218,2.280 and 2.331,respectively,and they did not increase or even decreased.Conclusion The number of the articles indexed by SCI-E increased year by year,much faster than that of CSTPCD.However,it does not necessarily mean the increase in impact.
