儿童性早熟研究的文献可视化分析

目的 分析国际上关于儿童性早熟的研究概况、热点及前沿进展,为我国相关研究提供思路。方法 检索Web of Science数据库中2010-2020年发表的相关期刊和综述论文;利用ISI Web of Knowledge自带的分析检索结果及创建引文报告功能,结合CiteSpace5.0.R1SE软件绘制知识图谱,对该领域研究的发文量、引文数、主要研究国家/地区、主要研究机构、引用文献、研究热点及研究前沿进行归纳总结。结果 共纳入1 966篇文献。2010-2020年期间该领域发文量快速增长;美国、中国因发文量大而占据领先地位;参与该类研究的机构涉及了圣保罗大学、哈佛大学医学院等多家机构;学科类别涉及遗传学、心理学、环境科学和公共健康等领域;近年来研究前沿包括基因突变、模拟治疗等。结论 伴随各国研究学者对性早熟关注度的上升,基因诊断,新治疗方法成为研究热点。我国在该领域的研究与国际前沿水平仍有差距,这需要我国学者在做好基础工作的同时,加强与国际专家的交流和合作,开展深入研究。

Visual analysis of the researches on precocious puberties

Objective To investigate the research status,hotspots and frontiers of the international researches on precocious puberties,so as to provide ideas for the development of related research in China.Methods Using bibliometric method,relevant journals and review papers from 2010 to 2020 were searched from Web of Science database.By analysis and retrieval results of ISI Web of Knowledge and its function of creating citation report,CiteSpace 5.0.R1 SE software was used to draw knowledge map.Quantitative statistics and qualitative analysis were conducted to summarize the research volume,citation number,main research countries/areas,main research institutions,cited reference,research hotspots and research frontiers in this field.Results A total of 1966 related literatures were retrieved,and the number of global published literatures in this field increased rapidly from 2010 to 2020.The dominant nations included America,China because of their large number of publications.Institutions involved University of Sao Paulo,Harvard Medical School most,and the category involved genetics,psychology,environmental sciences and public health.The research hotspots contained mutation,analog treatment over the past several years.Conclusions With the increasing attention of researchers from all over the world,gene diagnosis and new treatment methods have become the focus of research.But there is still a gap on the current research level in this field between China and abroad.It is required that Chinese scholars should strengthen exchanges and cooperation with international experts while doing the basic work.
