肺纤维化与代谢物相关的研究趋势:一项文献计量分析

Current trends in research on pulmonary fibrosis and metabolites: A bibliometric analysis

  • 摘要: 背景 代谢物与肺纤维化发生发展密切相关,其机制尚未完全阐明,需要深入探讨不同代谢物及原因所致肺纤维化形成的相关研究现状与趋势。

    目的 利用文献计量分析,探讨肺纤维化与代谢物相关研究的文献发表趋势与研究热点。

    方法 以“肺纤维化”和“代谢物”作为主要中文检索关键词,以“pulmonary fibrosis”和“metabolite”作为主要英文检索关键词,通过检索美国国家医学图书馆文献数据库查询系统(PubMed)、美国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),筛选相关文献至NoteExpress 3.0和Excel 2019中整理。进行发表年份分析、发文量分析、机构分析、国家/地区分析和期刊分析。采用VOSviewer 1. 6. 10对整理后的文献做可视化分析。将所有关键词进行录入,设置关键词出现的最低阈值为5次,对阈值过滤后的关键词做共现分析。

    结果 关于肺纤维化与代谢物的外文文献发表早于中文文献,从20世纪90年代起,外文和中文文献数量均呈增长趋势。外文文献1 062篇,其中带有作者地址信息的共864篇;发文量最多的是美国,发表340篇文章;中国位居第二,发表196篇文章;其他依次为日本、德国、意大利。中文文献共728篇,其中709篇包括作者机构信息,通过对相关机构进行合并整理,发现共有350家机构发表了相关的研究成果;发文量居于前6位的机构有华北理工大学、山西医科大学、北京大学、郑州大学、中国医科大学和苏州大学。刊出728篇中文文献的期刊共255种,发文量在10篇以上的期刊有12种,共发表242篇文献,占全部文献的33.24%;1 062篇外文文献在609种外文期刊上发表,发表文献数量在15篇以上的期刊共8种,共发表179篇文献,占全部文献的16.85%。关键词共现分析提示中外文献基本围绕肺纤维化与糖代谢、脂代谢、氨基酸代谢、核苷酸代谢及生物氧化开展研究。

    结论 近年来肺纤维化与代谢物研究的发文量呈上升趋势,研究热点涉及糖代谢、脂代谢、氨基酸代谢、核苷酸代谢及生物氧化。

     

    Abstract: Background Certain metabolites are closely related to the occurrence and development of pulmonary fibrosis, and the related mechanism has not been fully elucidated. It is necessary to explore the trends of various metabolites and causes of pulmonary fibrosis.

    Objective To discuss the trends of publication and research hotspots of pulmonary fibrosis-related metabolites by bibliometrics.

    Methods With "pulmonary fibrosis" and "metabolites" in both Chinese and English as primary keywords, literature search was conducted through public online databases: PubMed, Web of Science, SinoMed, and CNKI. NoteExpress 3.0 and Excel 2019 were used to store and organize the collected literature. Analyses included publication year, number of papers, institution, country/region, and journal title. VOSviewer 1.6.10 was used for visual analysis. Keyword co-occurrence was analyzed by setting the minimum threshold for the occurrence of keywords to 5 times.

    Results The research on pulmonary fibrosis and associated metabolites in foreign language was earlier than that in Chinese language. Since the 1990s, the number of literature showed an increasing trend in both foreign and Chinese language literature. A total of 1 062 articles were published in foreign languages, of which 864 articles contained the authors’ address information. The authors in the United States published 340 articles, followed by China with 196 articles, and then Japan, Germany, and Italy. There were 728 relevant pieces of literature published in Chinese, 709 of which included the authors’ institution information and 350 institutions were involved. North China University of Science and Technology, Shanxi Medical University, Peking University, Zhengzhou University, China Medical University, and Soochow University were the top 6 by number of publication. A total of 255 Chinese journals published 728 Chinese articles, and among them 242 articles (33.24%) were published by 12 journals having published more than ten articles per journal. A total of 1062 articles were published in 609 foreign language journals, and among them 179 articles (16.85%) were published by 8 journals with more than 15 articles published by each journal. The results of keywords co-occurrence analysis suggested that pulmonary fibrosis in association with glucose metabolism, lipid metabolism, amino acid metabolism, nucleotide metabolism, and biological oxidation were the common themes studied at home and abroad.

    Conclusion The number of publications on pulmonary fibrosis and metabolites has been on the rise in recent years, and the research hotspots include glucose metabolism, lipid metabolism, amino acid metabolism, nucleotide metabolism, and biological oxidation.
