Abstract: Objective：To analysis the cooperation， research topic and frontiers of the study of fuzzy logic in medical field in China， so as to provide the latest progress and references for the researchers. Methods： We searched the databases of CBM，CNKI and Wanfang to obtain the fuzzy logic study. The related publish time， author，organization， province and keywords were extracted and produced co-matrix by BICOMS-2. The network diagram of author， organization， province and keywords were drawn by NetDraw， at the same time， cluster analysised by gCLUTO.Results： A total of 284 studies involving 31 provinces and cities， 253 research units and 651 researchers were included.Members involved in the study were less. The cooperation was weak. The study focused on 3 aspects， fuzzy control/recognition in ECG/blood pressure using fuzzy system， artificial intelligence assess the risk of myocardial infarction patients through information retrieval/data mining， fuzzy theory/fuzzy logic/neural theory/fuzzy method/fuzzy mathematics in image processing/detection of sublingual collaterals in Chinese patients with diabetes mellitus/identification of traditional Chinese medicines/application of gastric dysplasia in diagnosis of hyperplasia/university libraries. Conclusion： Fuzzy logic related research in China has decreased slowly in recent years. The cooperation between researchers and institutions of different regions and organizations need to be further strengthened. The research themes still need to be further expanded.
