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.
Abstract:
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.  相似文献

Citation counts can identify landmark papers. The aim of this study was to identify and characterize the top‐cited articles in the pediatric liver transplantation literature. A search strategy for the Scopus® database was designed for pediatric liver transplantation publications from 1945 to 2014. The 50 top‐cited articles were analyzed. Author co‐citation analysis was performed using VOSviewer techniques. There were 2896 articles published between 1969 and 2015. The mean citation count of the top 50 cited articles was 166 (range 95‐635). There were three case reports in this top‐cited list. There were 15 collaborations in this top‐cited list with nine being international. The top‐cited publications originated in 12 countries, with the USA and the UK contributing 31 and seven articles, respectively. There were 14 authors with four or more publications in this list. There was a single author with nine publications in the top‐cited list. These top‐cited papers were found in 16 journals, with three journals collectively publishing over 50% of these publications. Pediatric liver transplantation research is an evolving entity. Surgical techniques and case reports are influential articles. Collaborations at a national and international level produce highly cited articles, which are found in influential journals.  相似文献

Aim: To test the hypotheses that published randomized clinical trials (RCTs) in neonatology with negative results (NR) are more likely to be published in journals with lower impact factor (IF) than those with positive results (PR); that there is an increase in the number of yearly published RCTs; that studies with large sample sizes are likely to be published in journals with higher IF. Methods: We used all English‐written RCTs registered in MEDLINE between 1/1/2001–31/12/2010 in the field of neonatology. Each RCT was classified as having a PR or NR. IF of each journal was determined for the year of publication. Results: We identified 329 RCTs. Yearly number of RCTs varied between 19 and 46, with no significant consistent linear increase over the years. There was no significant change over the years in average IF or in average patient size. IF and sample size of the studies were not significantly higher in studies with PR than in studies with NR. Conclusion: The number of RCTs per year in the field of neonatology has stabilized in the past 10 years, and RCTs with positive or negative results are published in journals of similar IF.  相似文献

AIM: This study aimed to investigate the characteristics of the most frequently cited articles published in 3 main journals dedicated to the field of pediatric surgery (Journal of Pediatric Surgery, Pediatric Surgery International and European Journal of Pediatric Surgery). MATERIAL AND METHODS: A search was initiated using the database (1985 - 2006) of the Science Citation Index of the Institute for Scientific Information. The total number of publications and their citation numbers were found and the most cited articles were investigated in detail. A total of 600 (200 from each journal) most cited articles were identified and chosen for further analysis. RESULTS: The total number of citations in these 3 journals was 20 271. The citations of the most cited articles ranged from 10 to 224. The articles were published between 1985 and 2003 and the mean number of citations/article was 33.78. Articles originated from 39 counties and 256 institutions. The leading countries were the United States (203 articles from 75 institutions), Germany (50 articles from 21 institutions), Japan (34 articles from 17 institutions), Switzerland (34 articles from 8 institutions), United Kingdom (32 articles from 19 institutions), and Canada (28 articles from 7 institutions). Of the institutions with the highest number of cited articles, four institutions were from the USA followed by Switzerland with two institutions. The leading topics were the gastrointestinal system (n = 239), respiratory system (n = 94), urology (n = 61) and oncology (n = 56), and diaphragmatic hernia (n = 41) was the most common special topic. There were 42 case reports (7 %) and 75 experimental research articles (12.5 %). Thirty-four authors from 14 countries and 30 institutions had articles in more than one journal. The most cited author was N. S. Adzick from the USA with 224 citations. CONCLUSION: In this study, we found that the Journal of Pediatric Surgery predominated with the greatest number of cited articles. The most cited articles, authors and institutions originated from the USA and English-speaking countries. The gastrointestinal system, respiratory system, urology and oncology were the leading topics and diaphragmatic hernia was the most common special topic.  相似文献

Abstract:
Objective To explore the articles, authors and citations of the articles published in Chinese Journal of Pediatrics, and have a clear view of the characteristics of this journal in its different development stages. Method Bibliometric methods were used to analyze the published articles,cooperation, regional distribution, core authors, corresponding authors and high-quantities of publication institutes, and also to calculate the number of citations per paper, types of citations, language-based citation number, Price index, self-cited rate and the distribution of journals based on citations. Result Totally 5534 academic articles were published during the 60 years, of which the number of articles written by more than one author was 4669 (80. 71% ), with a degree of collaboration as 3.87, and a rate of collaboration as 84. 37%. The number of articles by a single author was 865 ( 19. 29% ). As for the regions from where the papers were submitted, the top one was Beijing, which had 1495 articles published (27.01%). The top 15 institutes in number of articles had published 2254 articles ( 40. 73% ). The average citation rate was 84. 15%, and the number of citations was 48 854. The number of citations per paper was 10. 06, the Price index and self-cited rate were 55.57% and 6. 12%, respectively. The number of citations from foreign language literature was 35 781 (69. 1% ). The citation number of journals was 43 266 (84. 5% ), which is markedly higher than the citations of books and others. Conclusion Chinese Journal of Pediatrics has a wide distribution of authors and a high cooperative rate. This journal has a group of high-level core authors since founded in 1950, and it shows an adequate ability of absorbing and using scientific information. The articles published in this journal not only objectively reflected the distribution of the research powers, but also the development status of pediatrics in our country.  相似文献
