摘要:目的 分析国内外中医药治疗新型冠状病毒肺炎(以下简称“新冠肺炎”)的研究现状,为中医药在新冠肺炎防治领域的研究提供参考。方法 检索 2019-2020 年 Web of Science 核心合集数据库发表的中医药治疗新冠肺炎的相关文献,并进行文献计量分析,使用 CiteSpace5.7.R2 和VOSviewer1.6.16 软件进行可视化呈现,绘制相关知识图谱。结果 共纳入中医药治疗新冠肺炎相关文献 251 篇,发文国家共 51 个,我国以发文 189 篇成为在该领域研究最多的国家。国内研究机构以中医药大学及其附属医院为主,并形成了 6 个核心研究团队;其他国家包括美国、印度和英国等也有一定研究,大学是其主要研究机构,但研究力量相对分散,核心研究团队较少。研究热点主要集中在防治新冠肺炎中药的作用机制及通过循证医学方法对中医药治疗新冠肺炎临床试验的系统分析。结论 中医药治疗新冠肺炎已成为国内外的研究热点之一,其中中医理论、中药药理和中医临床试验研究最为核心。未来应重视传统中医学与现代科学理论和技术的有机结合,发挥中医药的优势及特长,为后疫情时代疫情防控和公共卫生体系建设发挥重要作用。关键词:中医药;新型冠状病毒肺炎;可视化分析;Web of Science 核心合集中图分类号:R259;G353.1 文献标识码:A 文章编号:2095-5707(2021)03-0006-06 DOI: 10.3969/j.issn.2095-5707.2021.03.002 开放科学(资源服务)标识码(OSID):

Abstract: Objective To analyze research status of COVID-19 treated with TCM at home and abroad; To provide references for further study of TCM in this field. Methods Relevant literature on the treatment of COVID-19 with TCM published in the Web of Science Core Collection database from 2019 to 2020 was retrieved, and a bibliometric analysis was conducted. CiteSpace5.7.R2 and VOSviewer1.6.16 software were used for visual presentation and related knowledge graphs were drawn. Results A total of 251 articles related to TCM treatment of COVID-19 were included, and 51 countries published articles. With 189 articles published, China has become the country with the most research achievements in this field. The main domestic research institutions were TCM universities and the affiliated hospitals, and 6 core research teams have been formed; other countries, including the United States, India, and the United Kingdom, also have certain research. Universities were the main research institutions, but the research strength was relatively scattered and the core
research team was relatively small. Research hotspots mainly focused on the mechanism of action of TCM in the prevention and treatment of COVID-19 and the systematic analysis of clinical trials of TCM in the treatment of COVID-19 through evidence-based medicine. Conclusion TCM treatment of COVID-19 has become one of the research hotspots at home and abroad, among which the theory of TCM, pharmacology of TCM and clinical trial of TCM are the core research. In the future, we should attach importance to the organic combination of traditional Chinese medicine with modern scientific theories and technologies, give full play to the advantages and specialties of traditional Chinese medicine, and play an important role in epidemic prevention and control and the construction of public health system in the post-epidemic era.

2020 年 3 月 11 日,世界卫生组织将新型冠状病毒肺炎(以下简称“新冠肺炎”)列为全球性大流行病[1]。新冠肺炎属中医学“疫病”范畴,中医
药在防治传染病方面积累了许多宝贵经验,形成了较为完整的传染病防治体系,对当前发生的新冠肺炎防治具有重要参考意义。据临床观察显示,中医药防治新冠肺炎的总有效率达90%以上[2]。
文献计量学以文献体系和文献计量特征为研究对象,采用数学和统计学方法,分析文献信息的分布结构、数量关系及变化规律[3]。CiteSpace 基于共引分析理论,对文献进行计量分析和可视化处理,在揭示学科发展规律和研究热点等方面具有显著优势[4];VOSviewer 在绘制知识图谱、解释学科主题关系等方面效果较好[5]。新冠肺炎是目前医学研究
领域的热点之一,但基于外文数据库以文献计量学和可视化方法开展的中医药治疗新冠肺炎的研究较少。基于此,本研究采用文献计量学方法对 Web of Science(WOS)核心合集数据库发表的中医药治疗新冠肺炎的文献进行分析,并利用 CiteSpace 和VOSviewer 2 种文献可视化软件绘制相关知识图谱,客观展示该领域的研究现状,探讨中医药治疗新冠肺炎的研究热点、难点及研究趋势,以期为相关研究者提供参考,并为全球疫情防控工作提供线索和思路。
1 资料与方法
1.1 数据来源与检索策略
本研究以 WOS 核心合集数据库为数据来源,将主题词设定为“COVID-19”OR“SARS-CoV-2” OR“2019-nCoV”OR“2019 novel corona virus”& “traditional Chinese medicine ” OR “herb ” OR “acupuncture”,由于 WOS 的自定义时间范围最小单位为年,因此将时间范围设定为 2019-2020 年。检索时间 2020 年 12 月 10 日。
1.2 纳入与排除标准
纳入研究性论文,文献类型为期刊文献。剔除非研究性及信息不全的文献。重复文献保留最新发表、信息内容最全的文献。
1.3 数据处理
将检索到的文献导入 EndNote 20 和 Excel 2019
中对重复文献进行清洗,并对关键词进行统一规
范,以提高数据的准确性。如将“Corona Virus Disease 2019”“COVID 19”“Coronavirus Disease 2019”“2019-nCoV”等统一为“COVID-19”;将“traditional Chinese medicine”“Chinese medicine” “Chinese traditional medicine”“TCM”等统一为“traditional Chinese medicine”。本研究综合运用CiteSpace5.7.R2 和 VOSviewer1.6.16 软件,客观展示发文国家、发文机构、研究作者和关键词聚类热点等内容。
