Keywords: Use of BIBLIOMETRICS, SCIENTOMETRICS, INFORMETRICS In LIS Research The authors have made a comparative analysis of research hot-spots in medical information in China in different periods of time using the co-words cluster analysis method of high frequency key words with the key words of papers published in Journal of Medical Informatics and Chinese Journal of Medical Library and Information Science. Results show that the research hot-spots were medical information service, medical library service, medical journal and literature retrieval before 1990, assessment of literature novelty and medical literature retrieval with medical information service weakened in 1991-2000, and networking, digitalization, quantification and personalization with insufficient research in medical information theories and methods from 2001 which should be strengthened.
