基于文献计量方法的免疫血小板减少症研究现状分析

目的 分析国际免疫性血小板减少症(ITP)的研究现状与研究热点.方法 检索科学引文索引扩展板(SCI-E)数据库2006-2016年ITP主题领域的文献,基于文献计量方法,应用Cite Space软件分析国际ITP研究的作者合作关系、时间分布、地域分布、发文机构分布及主题分布情况,重点对目前ITP的国际研究热点主题进行分析.结果 共检索到期刊论文936篇,2006-2015年ITP主题领域的文献量呈稳固上升趋势;研究主要分布于东亚、欧洲及北美洲地区,文献发文排名靠前的国家分别为美国、中国、日本、加拿大和英国;论文产出最多的机构为美国康奈尔大学.动物模型、血小板生成素受体激动剂、幽门螺杆菌根除、系统评价、T淋巴细胞增殖为研究热点;大剂量地塞米松、基因多态性、相关性、反应等高频关鍵词为最新研究方向.结论;本文明确了ITP主题领域研究的作者合作关系、地域分布,以及研究的热点与趋势,可以为我国ITP科研领域的发展提供参考.

Analysis on the research status on immune thrombocytopenia based on bibliometrics method

Objective To analyse the research status and research focus in immune thrombocytopenia.Methods The literatures of ITP subject category in the SCI-expanded (SCI-E) database during 2006-2016 were retrieved.Then the co-authorship,time distribution,research regional distribution,institute distribution,keywords distribution,especially the international hot research focus in ITP,were analyzed by using the Cite Space software base on the bibliometrics method.Results A total of 963 journal articles were retrieved,and the quantity of articles about ITP subjective category showed a steady increasing trend during 2006-2015.The researches mainly distributed in the east Asia,Europe and north America areas,and top issuing countries were American,China,Japan,Canada and England.The top issuing institution was the Cornell University.The anima model,thrombopoietin receptor agonist,Helicobacter pylori eradication,systematic review and T lymphocyte proliferation were the research hot points;the high frequency key words such as large dose of dexamethasone,gene polymorphism,correlation and reaction were the latest study direction.Conclusion The co-authorship,regional distribution,research hot points and trend are determined,which can provide references for ITP scientific field of our country.
