尘肺病与吸烟文献计量及热点可视化分析

Bibliometric and hot spot visualization analysis of pneumoconiosis and smoking

目的分析尘肺病与吸烟中英文文献的分布与关键词,探讨其特征及演变规律。方法于2020年11月,以美国国家医学图书馆文献数据库查询系统PubMed、美国科学引文索引(Web of Science)、中国生物医学文献服务系统(SinoMed)、中国期刊全文数据库(CNKI)为检索数据库,对尘肺病与吸烟相关中英文检索词进行文献检索。使用文献管理软件Note Express 3.5.0及文献计量分析软件VOS viewer 1.6.10对文献的发表年份、发表数量、国家、研究机构及关键词等进行分析。结果英文文献中尘肺病与吸烟相关研究共938篇,文献最早见于1962年;其中,美国发表文献数量最多(450篇),中国发表29篇文献,位居第4。中文文献中关于尘肺病与吸烟研究共601篇,文献最早见于1976年,发表文章最多的机构是中国医科大学(23篇),其次是兰州大学(15篇)。关键词共现分析显示,职业暴露、致癌性、风险因素、肺功能、DNA损伤是尘肺病与吸烟研究的主要研究热点。结论尘肺病与吸烟的研究聚焦于致癌性、风险因素、肺功能、DNA损伤机制等内容,为开展相关疾病预防与临床治疗提供研究热点。

Objective To analyze the distribution and keywords of Chinese and English literature on pneumoconiosis and smoking,and to explore its characteristics and evolutionary laws.Methods In November 2020,using PubMed,Web of Science,SinoMed,and CNKI as search databases,literature search was performed using Chinese and English search terms related to pneumoconiosis and smoking.The document management software Note Express 3.5.0 and the bibliometric analysis software VOS viewer 1.6.10 were used to analyze the publication year,number of publications,countries,research institutions and keywords.Results In the English literature,there were 938 articles about pneumoconiosis and smoking related research,and the literature was first published in 1962.Among them,the United States published the largest number of articles(450 articles),and China published 29 articles,ranking fourth.There were a total of 601 research articles on pneumoconiosis and smoking in Chinese literature.The literature was first published in 1976.The institution that published the most articles was China Medical University(23 articles),followed by Lanzhou University(15 articles).Keyword co-occurrence analysis showed that domestic and foreign literatures were the main research hotspots on occupational exposure,carcinogenicity,risk factors,lung function,and DNA damage of pneumoconiosis and smoking.Conclusion The research on pneumoconiosis and smoking focuses on carcinogenicity,risk factors,lung function,DNA damage mechanism,etc.,providing research hotspots for the prevention and clinical treatment of related diseases.
