摘要
目的:对眼科学文献进行计量分析,以确定其文献增长规律和发展趋势。方法:登录www.ncbi.nlm.nih.gov/PubMed后用"ophthalmology(眼科学)"检索从"1857/01/01到2010/12/31"的文献量,同时检索数据库中的年文献量(每5年为一时间段)、语言分布、中文收录情况、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:1857-2010年PubMed数据库收录眼科学文献111 993篇,逐年累计文献量均呈递增趋势,其方程近似直线(Y=3318.7X-7312,R2=0.8791)。1857-2010年眼科学文献以英语为主,其次是Japanese,Chinese,German,中文发表的文献排在第三位(2.10%),PubMed数据库收录中文眼科学文献从1971年开始,1991年后明显上升。根据PubMed数据库文献类型,包括Clinical Trial 6 259篇,Editorial 1 279篇,Letter 2 552篇,Meta-Analysis 133篇,Practice Guideline 67篇,Randomized Con-trolled Trial 3 644篇,Review8 202篇。根据Journal Groups分为Core Clinical journals 10 912篇,Dental journals 142篇,Nursing journals572篇。与Humans相关文献84 732篇,Animals相关文献20 449篇。PubMed中23种眼科学核心期刊收录文献54 155篇。结论:眼科学文献均呈上升趋势,表明眼科学的研究仍是一个热点,影响眼科学文献增长的主要因素是学科发展所处的环境条件。
Metrological analysis of ophthalmology literature to determine the increasing law and development trend of the literature.Log in www.ncbi.nlm.nih.gov/PubMed and use"ophthalmology"to retrieval"from 1857/01/01 to 2010/12/31"literature volume,meanwhile retrieval a database in literature volume(amount of every five years for a time period),language distribution,chinese collected,document type distribution,journal distribution,related research content and so on,according to the theory of increasing law of the literature,analyses the data which was retrievaled.From 1857 to 2010,PubMed database included 111993 articles of ophthalmology literature,all the cumulative literature volume increasing year after year,the approximate linear equation(Y=3318.7X-7312,R2=0.8791).1857-2010 ophthalmology literature was dominated in English,followed by Japanese,Chinese,German,literature volume published in Chinese was ranked in the three(2.10%),platoon PubMed included Chinese and beginning in 1971,1991 years later increased dramatically.According to the database literature PubMed types,including Clinical Trial 6259 articles,Editorial 1279 articles,Letter 2552 articles,Meta-Analysis 133 articles,Practice Guideline 67 articles,Randomized Controlled Trial 3644 articles,Review 8202 articles;ophthalmology literature included according to Journal Groups are divided into clinical Core Journals 10912 articles,Dental Journals 142 articles,Nuring Journals 572 articles;84732 article was related with Humans,Animals related literatures 20449 articles.PubMed core journal in 23 kinds of ophthalmology included 54155 articles.The amount of research articles about ophthalmology shows ascendant trend,indicate that glaucoma is still a hot tissue,the influence of the main factors to ophthalmology literature growth is the subject development in the environmental conditions.
