目的 了解中医药治疗慢性阻塞性肺疾病(COPD)稳定期的研究现状和趋势,为相关研究提供参考.方法 检索中国知识资源总库、万方数据知识服务平台、维普资讯中文期刊服务平台和中国生物医学文献服务系统建库至2022年9月1日收录的中医药治疗COPD稳定期研究文献.采用NoteExpress3.4软件统计文献基本信息,采用Excel2016统计第一作者、证型、方剂,绘制发文趋势图,根据布拉德福定律确定核心区域期刊数,根据普赖斯定律计算核心作者.采用VOSviewer1.6.18软件进行作者、关键词共现聚类分析,采用CiteSpace5.3.R4软件进行机构共现分析和关键词突现分析,绘制知识图谱.结果 共纳入3 360篇文献,涉及期刊445种、第一作者2 691位.该领域发文量总体呈增长趋势,临床研究为主要研究类型.核心区期刊21种,发文最多的为《新中医》.核心作者125位,发文最多的是李竹英和李建生.作者合作网络分析得到10个主要研究团队,规模最大的为李建生团队.涉及研究机构1 451个,多为中医药院校及其附属医院.COPD稳定期的证型共计62种,最常见的为肺脾气虚证,方剂共541种,最常用的为补肺汤.关键词共现分析得到8个主题,高频关键词为肺功能、临床疗效、生活质量、临床观察和中医药治疗.关键词突现分析得到22个突现词,布地奈德福莫特罗、六字诀、玉屏风散和炎性因子在当前关注度较高.结论 中医药治疗COPD稳定期的研究热度呈增长趋势,临床研究占比最大,但普遍质量不高,基础研究较为缺乏.研究热点集中在抑制气道炎症和免疫调节方面,肺功能和生活质量是最常用的评估指标.
Objective To understand the current status and trends of research on the TCM treatment for stable phase of chronic obstructive pulmonary disease(COPD);To provide references for relevant research.Methods Literature about TCM treatment for stable phase of COPD was retrieved from China National Knowledge Infrastructure,Wanfang Data,VIP Information Chinese Journal Service Platform,and SinoMed from the establishment of the databases to Sep 1,2022.NoteExpress 3.4 was used to sort out the basic data of papers.Excel 2016 was employed to count first authors,syndrome type,prescription and draw a run chart of publication,determine the number of journals in the core area according to Bradford law.Core authors statistically were analyzed according to Price law.Author collaboration network and keyword co-occurrence analysis were conducted using VOSviewer 1.6.18.CiteSpace 5.3.R4 was exploited to construct institutional collaboration network and study burst terms,and knowledge map was drawn.Results A total of 3 360 articles were included,involving 445 journals,with 2 691 first authors.The overall number of publications in this field showed an increasing trend,with clinical research being the main research type.There were 21 journals in the core region and the most frequently published journal was New Chinese Medicine.There were 125 core authors,with Li Zhuying and Li Jiansheng posting the most articles.Author collaboration network analysis showed 10 major research teams and the largest of which was Li Jiansheng's team.There were 1 451 institutions,mainly were universities and affiliated hospitals.There were 62 types of syndromes in the stable phase of COPD,the most common of which was the syndrome of qi deficiency of lung and spleen.There were 541 kinds of prescriptions in total,and the most commonly used was Bufei Decoction.Keyword co-occurrence analysis showed 8 subjects,and the high-frequency keywords included lung function,clinical efficacy,quality of life,clinical observation and TCM treatment.22 burst terms were obtained,with Budesonide Fumotro,six-word songs,Yupingfeng Powder and inflammatory factors highly concerned at present.Conclusion The research fever of TCM treatment for COPD in stable period shows an increasing trend,and clinical research accounts for the largest proportion,but the general quality is not high,and basic research is relatively lacking.The research focuses on the inhibition of airway inflammation and immune regulation,and lung function and quality of life are the most commonly used evaluation indicators.
