ABSTRACT
Objective To analyze the characteristics of papers published in Organ Transplantation in the past ten years. Methods The academic papers published in Organ Transplantation from January 2010 to December 2019 were retrieved from China National Knowledge Infrastructure (CNKI). The publication volume, the funded paper ratio, authors, research institutions and keywords were analyzed by information visualization software CiteSpace 5.3 and VOSviewer 1.6. Results From 2010 to 2019, a total of 919 academic papers were published in Organ Transplantation, with an average annual publication volume of 92, showing an overall stable trend. The funded paper ratio and the ratio of papers with funding support at the provincial level or above increased year by year, reaching 100% in 2019. High-yield authors mainly formed two research teams led by Shi Bingyi and Chen Guihua respectively. The first authors were distributed across China. In recent years, as many as 58 programmatic papers were published by national academic institutions, especially signed by Branch of Organ Transplantation of Chinese Medical Association. The average number of authors per paper was 4.94 in Organ Transplantation, and the proportion of papers contributed by two or more authors remained above 90% in recent years. According to the analysis of research institutions, the average number of institutions per paper was 1.60 in Organ Transplantation. Keyword co-occurrence network analysis demonstrated that liver transplantation, renal transplantation and organ transplantation were the research hotspots in the field of organ transplantation. Keyword cluster analysis showed that research mainly focused on 9 fields, such as liver transplantation, renal transplantation, organ transplantation, organ donation, posttransplantation complications, transplantation immunity, end-stage liver disease, xenotransplantation and stem cell transplantation. Keyword burst analysis showed that xenotransplantation, α-1, 3-galactose, transplantation immunity, apoptosis, donor specific antibody (DSA), antibody-mediated rejection (AMR) and flow cytometry were the research hotspots. Conclusions The authors that publish academic papers in Organ Transplantation come from major transplantation centers all over the country. The papers of Organ Transplantation cover the research hotspots of each branch in the field of organ transplantation, and include a large quantity of programmatic papers signed and published by national academic institutions, which show the frontier hotspots and the highest level of research in the field of organ transplantation in China, making Organ Transplantation an excellent academic journal.
