2003-2023年中国纤维支气管肺泡灌洗研究进展可视化分析

Visual analysis of research progress on fibrobronchial bronchoalveolar lavage in China from 2003 to 2023

目的分析中国纤维支气管肺泡灌洗(bronchoalveolar lavage,BAL)的研究现状,探索发展脉络及研究热点。方法检索2003—2023年中国知网、万方数据知识服务平台、维普中文期刊服务平台和中国生物医学文献服务系统收录的纤维BAL相关研究中文文献,提取关键词、作者、文献机构、文献发表时间等信息。应用Co-Occurrence14.9、VOSviewer 1.6.19、Microsoft Excel 2021软件进行数据清洗、数据统计和图形绘制,可视化呈现纤维BAL的研究热点及趋势。结果纳入符合要求的文献共4219篇。2021年发文量最多,为438篇。发文量3篇以上的核心作者共522人。发文量最多的机构和期刊分别为河北省儿童医院26篇和《临床肺科杂志》154篇。研究热点主要为肺炎、肺部感染、临床疗效、支气管肺泡灌洗液、支气管扩张和机械通气等。结论纤维BAL技术在中国呼吸系统疾病的诊断和治疗中应用广泛,未来应加强研究者间的协作,深化理论基础,完善临床应用体系,推动中国呼吸科事业的发展。

Objective To analyze the current research status of fibrobronchial bronchoalveolar lavage(BAL)in China,explore the development context and research hotspots.Methods This study was conducted from 2003 to 2023 by searching the Chinese literatures on fibrobronchial BAL collected from China National Knowledge Infrastructure,Wanfang Data Knowledge Service Platform,VIP and SinoMed,and extracting the information of keywords,authors,institutions and publication time of the literatures.Co-Occurrence14.9,VOSviewer 1.6.19 and Microsoft Excel 2021 were applied to carry out data cleaning,data statistics and graph rendering,and visualized the research hotspots and trends of fibrobronchial BAL.Results A total of 4219 literatures meeting the requirements were included.The largest number of articles will be 438 in 2021.There were 522 core authors with more than 3 published papers.The institutions and journals with the largest number of publications were Hebei Children’s Hospital with 26 articles and Journal of Clinical Pulmonary Medicine with 154 articles respectively.The research hotspots mainly include pneumonia,pulmonary infections,clinical efficacy,bronchoalveolar lavage fluid,bronchiectasis,and mechanical ventilation.Conclusion Fibrobronchial BAL is widely used in the diagnosis and treatment of respiratory diseases in China.In the future,it is necessary to strengthen the cooperation among researchers,deepen the theoretical basis,improve the clinical application system,and promote the further development of respiratory department in China.
