【摘要】：目的：探讨白内障(Cataract)研究文献的分布规律和发展趋势，为白内障相关研究课题提供依据。方法：利用PubMed数据库，采用文献计量学的方法，对1813-2011年所收录的白内障相关文献的年代分布及趋势、期刊分布、语种、类型、相关主题词、研究对象特征、全文及获取情况等进行统计分析。结果：1813-2011年底累计收录白内障研究文献47602篇，先天性白内障(n=3677)；老年性白内障(n=1610)；并发性白内障(n=830)；外伤性白内障(n=1036)；代谢性白内障(n=466)；辐射性白内障(n=2871)；后发性白内障(n=13413)。根据PubMed数据库文献类型，分为Review(n=3106)，RandomizedControlled Trial(n=1986)，Practice Guideline(n=23)，Meta-Analysis(n=71)，Letter(n=2262)，Editorial(n=536)，Clinical Trial(n=3047)，，Others(n=36571)；MEDLINE(n=45535)，Others(n=2067)；Nursing journals(n=463)，Core clinicaljournals(n=4172)， Others(n=42967)； Man(n=19400)， Woman(n=18693)，Others(n=9509)； Humans(n=38011)， Animals(n=6191)， Others(n=3400)；Infant(n=3244)，Child(n=8029)，Adult(n=10877)，Aged(n=19441)，80andover(n=6336)；Links to full text(n=25725)，Links to free full text(n=6950)，Abstracts(n=30087)。PubMed收录文献量自1946年逐渐增多，1961年后明显增多，增长趋势近似直线(y=598.71x－689.92, R2=0.9746)。白内障研究文献以英语为主(36120，75.9%)，中文发表的文献量排在第7位(762，1.6%)。PubMed中21种眼科学相关期刊(SCI收录期刊)收录以白内障为主题词的文献共有3825篇。结论：研究表明，白内障相关研究起始于19世纪初，20世纪60年代开始受到人们的广泛关注，其后的文献量增长近似直线则是一个佐证。目前白内障研究仍是人们关注的一个热点。
[Abstract]:Objective: To investigate the distribution and development trend of the literature on cataract (Cataract), and to provide a basis for cataract related research.
Methods: using PubMed database and bibliometric method, we analyzed the distribution and trend of cataract related literature in 1813-2011 years, including journal distribution, language type, related subject words, research object characteristics, full text and acquisition situation.
Results: by the end of 1813-2011 a total of 47602 literatures study included cataract, congenital cataract (n=3677); senile cataract; cataract (n=1610) (n=830) (n=1036); traumatic cataract; metabolic cataract (n=466); radiation cataract (n= 2871); after cataract (n=13413). According to the PubMed database document type, divided into Review (n=3106), RandomizedControlled Trial (n=1986), Practice Guideline (n=23), Meta-Analysis (n=71), Letter (n=2262), Editorial (n=536), Clinical Trial (n=3047), Others (n=36571); MEDLINE (n=45535), Others (n=2067); Nursing journals (n=463), Core clinicaljournals (n=4172), Others (n=42967); Man (n=19400), Woman (n=18693), Others (n=9509); Humans (n=38011), Animals (n=6191), Others (n=3400); Infant (n=3244), Child (n=8029), Adult (n=10877), Aged (n=19441), 80andover (n =6336; Links to) full text (n=25725), Links to free full text (n=6950), Abstracts (n=30087).PubMed papers increased since 1946, increased significantly after 1961, the growth trend of the linear approximation (Y=598.71x689.92, R2=0.9746). The cataract literatures in English (36120,75.9%), the amount of literature published Chinese row in seventh (762,1.6%) 21 ophthalmology related journals.PubMed (SCI journals included) to cataract as the theme a total of 3825 articles.
Conclusion: studies have shown that cataract related research started in the early nineteenth Century, and began to receive widespread attention in 1960s. The growth of the literature is approximately a straight line. Currently, cataract research is still a hot topic.
