Bottom Line: G7 countries are the leading nations for translational medical research.Some developing countries, such as P.R China, also play an important role in the communication of translational research.The USA and its institutions play a dominant role in the production, collaboration, citations and high quality articles.

ABSTRACT

Background: Translational medical research literature has increased rapidly in the last few decades and played a more and more important role during the development of medicine science. The main aim of this study is to evaluate the global performance of translational medical research during the past few decades.

Methods: Bibliometric, social network analysis, and visualization technologies were used for analyzing translational medical research performance from the aspects of subject categories, journals, countries, institutes, keywords, and MeSH terms. Meanwhile, the co-author, co-words and cluster analysis methods were also used to trace popular topics in translational medical research related work.

Results: Research output suggested a solid development in translational medical research, in terms of increasing scientific production and research collaboration. We identified the core journals, mainstream subject categories, leading countries, and institutions in translational medical research. There was an uneven distribution of publications at authorial, institutional, and national levels. The most commonly used keywords that appeared in the articles were "translational research", "translational medicine", "biomarkers", "stroke", "inflammation", "cancer", and "breast cancer".

Conclusions: The subject categories of "Research & Experimental Medicine", "Medical Laboratory Technology", and "General & Internal Medicine" play a key role in translational medical research both in production and in its networks. Translational medical research and CTS, etc. are core journals of translational research. G7 countries are the leading nations for translational medical research. Some developing countries, such as P.R China, also play an important role in the communication of translational research. The USA and its institutions play a dominant role in the production, collaboration, citations and high quality articles. The research trends in translational medical research involve drug design and development, pathogenesis and treatment of disease, disease model research, evidence-based research, and stem and progenitor cells.

Figure 11: Timeframes of keywords in the period of 2001–2011.

Mentions: The technique of statistical analysis of keywords and title-words may indicate directions of research. Especially, authors’ keywords analysis could offer information on research trends as viewed by researchers [19]. The high percentage of once-only author keywords probably indicates a lack of continuity in research and a wide disparity in research focuses. Another reason is that these keywords might not be standard or widely accepted by researchers. Author keywords appearing in the articles referring to translational medical research from 1993 to 2012 were calculated and ranked. The top eight author keywords used and distribution during the last 20 years are displayed in Figure 11, where research variations can be roughly grasped. Except for “translational research,” and “translational medicine” which were search words, the top six most frequently used keywords were “biomarkers”, “stroke”, “inflammation”, “cancer”, “biomarker”, and “breast cancer.”
