基于CiteSpace的创伤性脑损伤研究文献计量学分析

目的通过对创伤性脑损伤（TBI）研究文献进行计量学分析，探索TBI领域的研究热点和研究趋势。 方法基于Web of Science核心数据库检索2016~2020年TBI研究的相关文献，通过CiteSpace.5.8.R3对发表文章年度分布、作者、机构、国家、期刊、被引情况和关键词等进行分析，并根据关键词的词频、中心性和聚类情况探讨TBI领域的研究热点和趋势。 结果（1）筛选后共纳入14 991篇文献，美国是发文量最多的国家，哈佛大学医学院是发文量最多的机构。（2）氧化应激、死亡率、儿童TBI、创伤后应激障碍、康复治疗是近5年TBI领域研究热点。（3）TBI的模型及损伤效应-生物学机制-诊断及治疗指南-个体治疗是TBI研究领域的研究趋势。 结论青少年人群TBI的损伤效应、分子机制、治疗方法的可靠性及有效性是TBI领域现在和未来研究的重点和方向。

Bibliometric analysis of traumatic brain injury studies based on CiteSpace

ObjectiveTo explore the research hotspots and trends in the field of TBI by bibliometric analysis of the literature on traumatic brain injury (TBI). MethodsThe relevant literature on TBI research from 2016 to 2020 were retrieved based on the core database of Web of Science. The annual distribution, author, institution, country, journal, citation and keywords of published articles were analyzed through CiteSpace.5.8.R3 and the research hotspots and trends in the field of TBI were discussed according to the word frequency, centrality and clustering of keywords. Results(1) A total of 14 991 articles were included after screening. The United States was the country with the most publications, and Harvard Medical School was the institution with the most publications. (2) Oxidative stress, mortality, children’s TBI, post-traumatic stress disorder, and rehabilitation treatment have been the hot spots in the field of TBI in recent 5 years. (3) TBI model and injury effect-biological mechanism-diagnosis and treatment guidelines-individual treatment is the research trend in the field of TBI research. ConclusionThe damage effect, molecular mechanism, reliability and effectiveness of treatment in the adolescent population are the focus and direction of current and future research in the field of TBI.
