中医药调节miRNA研究文献可视化分析

Visualization Analysis on Research Literature of TCM Regulation of miRNA

目的应用可视化方法分析中医药调节微小核糖核酸(miRNA)研究现状及趋势。方法检索中国知识资源总库(CNKI)、中文科技期刊数据库(VIP)、中国学术期刊数据库(万方数据)建库至2022年5月31日收录的中医药调节miRNA研究文献。采用Excel2019、VOSviewer1.6.18、CiteSpace5.8.R3软件对纳入文献的发表年份、来源期刊、作者、关键词等内容进行可视化分析。结果共纳入文献787篇,发文量持续上升,发文较多的期刊包括《中国实验方剂学杂志》《中华中医药杂志》《中华中医药学刊》等。形成以王阶、刘喜德、刁丽梅等为代表的多个研究团队,团队间合作不甚紧密。文献关键词分析显示,研究内容主要集中在凋亡、miRNA-21、电针、动脉粥样硬化、增殖等相关领域;中药干预措施中占比最高的是中药提取物(42%);频次≥3的miRNA共24个,研究最多的类型是miRNA-21。结论中医药调节miRNA研究的热点主要为各类中医药治疗手段经调节miRNA改善细胞自噬、凋亡、炎症反应等途径的分子机制,研究趋势为基于精准治疗策略的名中医经验方的机制研究。

Objective To analyze the current status and trends of TCM regulation of microRNA(miRNA)using visualization methods.Methods The literature related to the TCM regulation of miRNA was retrieved from CNKI,VIP and Wanfang Data from the establishment of the databases to May 31,2022.Excel 2019,VOSviewer 1.6.18,and CiteSpace 5.8.R3 software were applied to visualize and analyze the year of publication,journal source,author and keywords of the included literature.Results A total of 787 articles were included,and the number of publications continued to rise.Source journals with more publications includes Chinese Journal of Experimental Traditional Medical Formulas,China Journal of Traditional Chinese Medicine and Pharmacy,Chinese Archives of Traditional Chinese Medicine,etc.Research teams were formed with Wang Jie,Liu Xide,Diao Limei,etc.as the representatives,and the cooperation among the teams was not very close.Analysis on the keywords in the literature showed that the studies mainly focused on apoptosis,miRNA-21,electroacupuncture,atherosclerosis,proliferation and other related fields;TCM intervention that accounted for the most research were extracts of Chinese materia medica,with 42%of the studies;there were 24 miRNAs studied≥3 times,and the most studied miRNA was miRNA-21.Conclusion The research hotspots of TCM regulation of miRNA are mainly the molecular mechanism of various TCM therapeutic tools to improve cell autophagy,apoptosis,inflammatory response and other pathways through regulation of miRNAs.The trend of research is to study the mechanism of empirical prescriptions of famous TCM practitioners based on precise therapeutic strategies.
