目的对国内近5年儿童哮喘领域的期刊论文研究热点进行分析和讨论。方法以中国知网数据库为检索来源,以关键词"哮喘and和儿童"或"儿童哮喘"或"哮喘儿童"进行国内近5年(时间限定在2009年9月至2014年9月)期刊论文的检索。以SPSS 18.0和EXCEL作为数据处理工具,采用自编程序和共词-聚类分析方法进行相关分析。结果共检索文献5 220篇,去除无关键词和计算机自定义的异常数据后剩余5 191篇。近5年国内儿童哮喘相关文献数量呈增长趋势,共有3 379位作者在517种期刊上共计发表期刊论文5 191篇,文献来源于全国30个省市。我国儿童哮喘近5年的研究主题主要围绕儿童哮喘的诊治及流行病学、病因学研究、急性发作的治疗及护理、哮喘相关发病机制、哮喘管理、哮喘稳定期及咳嗽变异性哮喘的诊治、中医治疗等七个方面。结论共词-聚类分析方法在一定程度上直观展示了我国近5年儿童哮喘的临床工作重点及其研究热点,可为相关研究人员及临床工作者提供相关领域的信息支持,为科研选题及临床实践提供参考依据。

Objective To analyze and discuss the research hotspots of childhood asthma in last 5 years refereed journal papers in China. Methods The research was underwent in China national knowledge infrastructure（CNKI） database from September 2009 to September 2014, and the search key words were ＂ asthma and children＂, ＂ childhood asthma＂ or ＂asthmatic children＂.

The amount of childhood asthma relative papers in last 5 years had a tendency to increase. There were 3 370 authors from more than 30 provinces and cities across China published 5 191 papers in 517 kinds of journals.
