Global research status and trends of interactions between Traditional Chinese medicine and pulmonary fibrosis: A new dawn in treatment
Abstract
Background: Pulmonary fibrosis (PF) remains a major sequela of COVID-19, yet its pharmacotherapy remains unsatisfactory. Recently, Traditional Chinese medicine (TCM) has garnered increasing recognition among patients and researchers because of its few side effects and efficacy. The objective of this study is to use bibliometric analysis to explore the current research landscape and emerging trajectories of TCM treating PF(TCM/PF) researches, and comprehensively evaluate publications with substantial citations within the domain of TCM/PF. Materials and methods: TCM/PF publications from 1996 to June 15, 2023 were identified by a comprehensive search of the Web of Science Core Collection (WoSCC). The Bibliometrix of Origin, CiteSpace, Gephi, dycharts and VOSviewer were used for bibliometric analysis. Results: A total of 358 papers were included. A rapid increase in the number of papers after 2013 was observed. China had the highest publication output and research contributions in this field. Beijing University of Traditional Chinese Medicine and Nanjing University of Traditional Chinese Medicineare leaders in productive research of this field. Nanjing University of Traditional Chinese Medicine had the highest citations (227). LI JIANSHENG from Henan University of Chinese Medicine was the most prolific author (8), with the highest number of citations (61), and TONG XIAO LIN from China Academy of Chinese Medical Sciences had the highest H-index (30). The leading journal publishing the most research (37) is Frontiers in Pharmacology and the Journal of Ethnopharmacology had the highest total citations (486). Burst analysis of keywords revealed three distinct phases of research. 1996 to 2013 marked the nascent stage of TCM/PF research; from 2014 to 2018, studies gradually focused on the underlying mechanisms governing TCM/PF. The most significant phase occurred from 2019 onward, where TCM/PF exhibited an explosive growth trend. This progression signifies a transition from foundational explorations to a comprehensive understanding of the mechanisms involved, ultimately leading to the current surge in research activities focused on TCM/PF. Notable research teams of this stage, led by LI JIAN SHENG and TONG XIAO LIN, have been at the forefront of advancing TCM/PF research. Their studies on Jinshui Huanxian formula and Qimai Feiluoping decoction have been pivotal in advancing the frontier of research in this domain. Furthermore, the monomeric compounds, including emodin, curcumin, salvianolic acid, baicalin, and oxymatrine, have sustained longstanding prominence. Conclusions: This study gained insight into the research status, focal areas and evolving trends of global TCM/PF research. It also identified the most cited articles in TCM/PF and analyzed their characteristics, which may hold significant relevance for both clinical researchers and practitioners on future directions in this field.
