目的:对青光眼文献进行计量分析,以确定文献增长规律和发展趋势。方法:登录www.ncbi.nlm.nih.gov/PubMed后用"glaucoma(青光眼)"检索"从1858-01-01/2010-12-31"的文献量,同时检索数据库中文献的年文献量(每5a为一时间段)、中文收录情况、语言分布、文献类型分布、期刊分布、相关研究内容情况等,根据文献增长规律的理论,对检索出的数据进行分析。结果:1858/2010年PubMed数据库收录青光眼文献45514篇,逐年累积文献量均呈递增趋势,其方程近似直线(Y=579.34X-568.38,R2=0.882)。1858/2010年青光眼文献以英语为主导(71.50%),中文发表的文献量排在第12位(0.31%),PubMed收录中文青光眼文献从2006年开始,2009年后明显上升。根据PubMed数据库文献类型,包括Clinical Trial(2947篇)、Editorial(648篇)、Letter(1727篇)、Meta-Analysis(81篇)、Practice Guideline(15篇)、Randomized Controlled Trial(1787篇)、Review(3633篇)、Others(34678篇);收录青光眼文献根据JournalGroups分为Core Clinical Journals(625篇)、Dental Journals(5篇)、Nuring Journals(42篇)、Others(44844篇);与Humans相关文献37194篇,Animals相关文献4223篇,Others为4099篇。PubMed中19种青光眼核心期刊收录文献20526篇(45.10%)。结论:青光眼研究的文献量均呈上升趋势,表明青光眼的研究仍是一个热点,影响青光眼文献增长的主要因素是学科发展所处的环境条件。

AIM:To determine the growth rule and trendency of the glaucoma literature by bibliometric analysis.METHODS:Logging in www.ncbi.nlm.nih.gov/PubMed,"glaucoma" was used to retrieve from 1858-01-01 to 2010-12-31 literature volume,meanwhile,literature volume(amount of every five years for a time period),Chinese collected,language distribution,document type distribution,journal distribution,and related research content in a database were retrieved,according to the theory of increasing law of the literature,the data retrieved were analysed.RESULTS:From 1858 to 2010,PubMed database included 45514 articles of glaucoma literature,all the cumulative literature volume was increasing year by year,the equation was approximate line(Y =579.34X-568.38,R2=0.882).1858-2010 glaucoma literature was dominated in English(71.50%),literature volume published in Chinese was ranked in the twelveth(0.31%),PubMed began to include Chinese glaucoma literature in 2006,which increased dramatically after 2009 years.According to the PubMed database literature types,it included Clinical Trial(2947 articles),Editorial(648 articles),Letter(1727 articles),Meta-Analysis(81 articles),Practice Guideline(15 articles),Randomized Controlled Trial(1787),Review(3633 articles),Others(34678 articles);glaucoma literature included according to Journal Groups were divided into Core Clinical Journals(625 articles),Dental Journals(5 articles),Nursing Journals(42 articles),Others(44844 articles);37194 articles were related with Humans,Animals related literatures were 4223 articles,Others 4099.Nineteen kinds of glaucoma core journal in PubMed included 20526 articles(45.10% collected literature).CONCLUSION:The amount of research articles about glaucoma shows ascendant trend,indicating that glaucoma is still a hot tissue,the main factors of the influence on glaucoma literature growth is the environmental conditions of subject development.
