Visual Analysis of Literature on Spleen Deficiency Syndrome of Functional Dyspepsia in China over the Past 20 Years
Objective To understand the current status and hot spots of research on spleen deficiency syndrome of functional dyspepsia in China,and to provide reference for clinical treatment and mechanism research of this disease.Methods Research literature on spleen deficiency syndrome of functional dyspepsia included in the three major Chinese databases CNKI,Wanfang database and VIP from January 1,2000 to June 16,2023 were searched and manually screened.NoteExpress 3.6.0.9220 was used to screen duplicate research literature and manage them,and CiteSpace 5.7.R5 software was applied to draw cooperative network graphs and tables of authors and their research institutions,construct co-occurrence network graphs and tables of keywords,emergent graphs,clustering network graphs and tables,and clustering timeline graphs,and analyze them one by one.Results A total of 407 research papers on spleen deficiency in functional dyspepsia were included,with an overall fluctuating upward trend in the number of annual publications;the high-producing authors were Tang Xudong,Lv Lin,Wang Fengyun,Zhang Shengsheng,Huang Suiping,Yin Xiaolan,and Ma Xiangxue in order;the research institutions with more publications were Beijing University of Traditional Chinese Medicine,Hunan University of Traditional Chinese Medicine,Xiyuan Hospital of the Chinese Academy of Traditional Medicine,Beijing Hospital of Traditional Chinese Medicine affiliated to Capital Medical University,and the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine,in order;The high-frequency keywords were"functional dyspepsia","liver depression and spleen deficiency","spleen deficiency and qi stagnation","Chinese medicine therapy","clinical research","spleen deficiency syndrome",etc.Accordingly,a list of high-centered keywords(centrality≥0.1),the top 20 emergent words,14 clustering labels and a timeline diagram of research literature were generated.Conclusion The research direction of functional dyspepsia spleen deficiency in China is mainly focused on three aspects:TCM syndrome type,clinical research and mechanism research.
