Abstract:
Objective:To explore the research hotspots and evolutionary trends in the field of wound repair mechanism research.Methods:This study was a bibliometric analysis study. English literature related to wound repair mechanism published in the core collection of Web of Science database from the establishment of the database to December 26 th, 2023 that met the inclusion criteria were retrieved. The annual number of publications and their citations were counted, and the change trend was analyzed. Based on the aforementioned annual publication volume, the relevant literature in the core collection of Web of Science database in this field from the first 5 years when the publication growth in this field was rapidly turning, to December 31 st, 2023 was searched again, and the total number of publications was recorded and annual growth rate of published literature was calculated; and based on the trend line of annual publication volume, the publication volume in this field in 2024 was predicted. The CiteSpace 6.2.R4 software was used for visualized analysis of the literature from the second retrieval, including the source journals, the cited literature, and the keywords, to discuss the current research status and the evolution of hotspots of wound repair mechanism. Results:The first search retrieved a total of 3 992 literature related to the research on wound repair mechanisms, among which the annual number of publications and their citations increased rapidly from 2015 to 2023. The time limit for the second retrieval was set to be from January 1 st, 2011 to December 31 st, 2023, during which a total of 3 206 literature was published, with an average annual growth rate of 13.30%. According to the publication trend line at this stage, it was predicted that the number of publications in this field will reach 500 in 2024. The literature from the second retrieval was published in 717 journals. The research directions of the top 10 journals with the most published literature (accounting for 18.75% (601/3 206) of the total number of publications) mainly focused on trauma, molecules, pharmacology of Chinese medicine, and stem cells, with the United Kingdom and the United States, etc. as the main publishing countries. There were 7 journals with impact factors >5 and 6 journals belonging to the Q1 or Q2 areas of the Chinese Academy of Sciences. There were 906 nodes and 9 large clusters for the keywords of cited literature of literature from the second retrieval (Q=0.64, S=0.82). The main clusters of cited literature of literature from the second retrieval were #2 matrix metalloproteinases and #3 transforming growth factor β 1 from 2006 to 2015, #1 macrophage polarization, #4 mesenchymal stem cells, #6 antibacterial, and #7 plant extraction from 2016 to 2023. During 2021-2023, the main clusters of cited literature of literature from the second retrieval being #1 macrophage polarization, #4 mesenchymal stem cells, #6 antibacterial, and #7 plant extraction had the most closely related co-occurrence. The analysis of the top 5 cited literature of literature from the second retrieval with high citation value, high centrality value, and high Sigma value showed that the main research directions were the influence of macrophages and inflammation regulation on wound repair, the influence of fibroblasts on wound repair, and the influence of growth factors and cytokines on wound repair. The keywords of literature from the second retrieval formed 636 nodes and 7 clusters, that being #0 antibacterial, #1 mesenchymal stem cells, #2 cell migration, #3 wound repair, #4 exosomes, #5 negative pressure wound treatment, and #6 diabetic foot ulcer (Q=0.59, S=0.80). For the literature from the second retrieval, the main clusters from 2016 to 2023 were #0 antibacterial, #1 mesenchymal stem cells, and #4 exosomes, and the main clusters before 2015 were #2 cell migration and #3 wound repair. A total of 110 burst keywords (hereinafter referred to as burst words) were formed for the keywords of literature from the second retrieval, and the top 10 burst words in terms of intensity were mouse, gene expression, skin injury, epithelial cells, signaling pathways, biomaterials, exosomes, molecular docking, hydrogels, and macrophage polarization, with different start and end time periods. Among them, the high-intensity burst words from 2021 to 2023 were hydrogel (belonging to cluster #0 antibacterial), exosome (belonging to cluster #1 mesenchymal stem cells), molecular docking (belonging to cluster #0 antibacterial), and macrophage polarization (belonging to cluster #0 antibacterial). Conclusions:In the future, the development of wound repair mechanism research will still be at a steady phase. The research hotspots in this field have shifted from growth factors and wound repair physiology to antibacterial and stem cells. Future research directions in this field may include using molecular docking technology and network pharmacology to screen drugs that promote wound repair and study their underlying mechanisms, the regulation of macrophage polarization by exosomes, and the mechanism by which hydrogels promote wound healing through antibacterial effects.
