基于Web of Science的肠道菌群文献计量学分析

[目的]从文献计量学角度分析1900～2010年肠道菌群研究状况。[方法]以美国ISI Web of Science的Science Citation Index Ex-panded(SCIE)引文数据库为检索对象,检索1900～2010年SCIE收录的有关肠道菌群的文献,分别对不同国家、机构、著者的发文量、被引频次、文献来源期刊及论文学科分布等进行统计分析。[结果]1900～2010年共有肠道菌群文献8 838篇,分布于490多种期刊,载文量居前10位的期刊中影响因子最高的3种期刊分别是Gastroenterology(12.899)、Gut(9.357)和American Journal of Clinical Nutrition(6.307);主要学科分布为Microbiology(1 509篇,17.07%)、GastroenterologyHepatology(935篇,10.58%)和PharmacologyPharmacy(894篇,10.12%);发文量居前3位的国家分别为美国(2 005篇,22.69%)、日本(1 031篇,11.67%)和英国(688篇,7.78%),中国发表文285篇,占总量的3.22%,居世界第10位;发文量居前3位的作者分别为韩国的Kim,DH(118篇)、瑞典的Nord,CE(102篇)和英国的Gibson,GR(89篇);发文量居前3位的机构是KAROLINSKA INST(瑞典卡罗林斯卡学院,185篇)、INRA(法国国家农业研究所,168篇)和KYUNG HEE UNIV(韩国庆熙大学,118篇),中国研究机构中发文量最多的是中国科学院(CHINESE ACDA SCI),发文45篇,其次是上海交通大学和浙江大学,均发文20篇。[结论]美国、英国、日本等发达国家在肠道菌群领域的研究居领先水平,中国在这一领域也做出了重要贡献,处于相对前列,但与领先国家和机构相比还存在相当大的差距。

Bibliometric Study of the Articles on Intestinal Flora Based on Web of Science

[Objective] To analyze the research status of articles on intestinal flora from 1900 to 2010 using a bibliometric approach.[Method] Literature on intestinal flora from the Web of Science's Science Citation Index Expanded database during 1900-2010 was searched.The search results were analyzed with regard to the number of articles and the frequency of citations by country,institution and author,journal of publication,and subjects covered by the article.[Result] In total,8838 articles related to intestinal flora were published and distributed in more than 490 kinds of journals from 1900 to 2010,covering Microbiology(1 509 articles,17.07%),Gastroenterology & Hepatology(935 articles,10.58%),and Pharmacology & Pharmacy(894 articles,10.12%).The three journals with the highest impact factors were Gastroenterology(12.899),Cut(9.537) and American Jornal of chinical Nutrition(6.307);The top 3 countries in terms of articles published were USA(2 005 articles,22.69%),Japan(1 031 articles,11.67%) and UK(688 articles,7.78%),China(285 articles,3.22%) ranked the 10th in the world.Kim DH(Korea,118 articles),Nord CE(Sweden,102 articles) and Gibson GR(UK,89 articles) published the most articles.KAROLINSKA INST(Sweden,185 articles),INRA(French National Institute for agricultural research,168 articles)and KYUNG HEE UNIV(Korea,118 articles) accounted for the top 3 total number of the papers,and the top 3 institutions in the largest number of papers in China were Chinese Academy of Sciences(45 articles),Shanghai Jiaotong University(20 articles) and Zhejiang University(20 articles).[Conclusion] Developed countries played a leading role in research on intestinal flora.China also had made significant contributions to the progress of the related research.But there were still considerable gaps between China and other leading countries and institutions.
