Bibliometrics and visual analysis of platelet rich plasma based on strategic coordinate diagram and co-word analysis / 中国输血杂志

ABSTRACT

【Objective】 To explore the research status, hot spots and trends of platelet rich plasma (PRP). 【Methods】 With "platelet rich plasma (PRP)" and its Chinese equivalent as the subject words, the PRP related articles during January 1, 2013 to December 31, 2022 from PubMed and CNKI database were retrieved. The bibliometric analysis was performed by Bicomb 2.0 software to extract the annual number of literature publications, authors, journals and high-frequency theme words/sub theme words. The gCLUTO software was used to evaluate and visualize the results, and strategic diagram was drawn according to the results of biclustering. 【Results】 A total of 9 066 PRP related articles were retrieved (7 027 from PubMed, 2 039 from CNKI), and the number of publications showed an increasing trend year by year. Papers have been published in 1 527 journals in PubMed, among which the journal with the highest number of publications was Arthroscopy: Journal of Arthroscopic & Related Surgery (175 articles), followed by American Journal of Sports Medicine (171 articles ) and Journal of Cosmetic Dermatology (121 articles) . PRP-related studies were published in 541 journals in CNKI, with the top 3 journals as Chinese Tissue Engineering Research (113 articles), Chinese Aesthetic Medicine (64 articles) and Chinese Journal of Blood Transfasion (45 articles) . In Pubmed, Anitua Eduardo (84 articles), Filardo Giuseppe (53 articles) and Cole Brian J (44 articles) were the top three productive authors on PRP; Cheng Biao from the General Hospital of Southern Theater Command of Chinese PLA was the most productive Chinese author (25 articles) . Shan Guiqiu from the General Hospital of the Southern Theater Command of the Chinese People's Liberation Army published the most articles(29 articles) in CNKI. American journals published the most articles (2 745 articles ), accounting for 39.06% of the total articles, followed by British and Swiss journals, with 1 499 articles and 550 articles, respectively. A total of 42 high-frequency subject words/sub-subject words were selected from PubMed, and were classified into 6 roups, while 30 high-frequency subject words were selected from CNKI and grouped into 5 categories. The strategic coordinates show that the treatment of rotator cuff and tendon injury with PRP in PubMed, the study of PRP and tissue engineering materials in CNKI are the core themes of current PRP research. 【Conclusion】 The strategic coordinate map and bibliometrics can reveal the current research status of PRP and predict future research hotspots, but current research cores of PubMed and CNKI are not consistent, and further research is still needed.
