OBJECTIVEThis study was designed to investigate the influence of journals indexed by Science Citation Index (SCI) on Chinese medical journals.

METHODArticles 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.

RESULTTotally 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.

CONCLUSIONThe 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.

OBJECTIVEThe present study was designed to explore the cited status and its correlated factors of articles published in Chinese Journal of Pediatrics.

METHODArticles published in Chinese Journal of Pediatrics from 2001 to 2010 were searched using Wanfang Medical Online database, and the relationship between cited number and column and funding status were analyzed.

RESULTSTotally 3209 articles were published by Chinese Journal of Pediatrics from 2001 to 2010. Two thousand and seventy-three articles (64.60%) were cited. The total cited number was 18 546 (mean rate: 5.78 per paper). Standard/protocol/guideline was the most often cited column (mean rate: 62.92 per paper). Featured articles including editorials (mean rate: 7.12 per paper), special articles (mean rate: 6.50 per paper) and original articles (mean rate: 7.90 per paper) had higher cited rate. Cited rate of original papers in featured articles was higher than other original articles (mean rate: 6.03 per paper). Those with academic perspectives, such as Opinion/Debate/Discussion, were well cited (mean rate: 7.09 per paper). All of original articles in Rapid Pathway were well cited (mean rate: 16.20 per paper). Mean cited number of grant-supported articles was 4.81 per paper, lower than that of all kinds of papers (mean rate: 5.78 per paper) and non-grant-supported articles (mean rate: 6.06 per paper). However, it was slightly higher than that of articles except Standard/protocol/guideline (mean rate: 4.36 per paper).

CONCLUSIONCited status varies among columns. The invited papers should be increased in number to raise commentary papers and original articles with high quality.Grant-supported or non-grant-supported papers should be reviewed based on the same standard after submission.
