Objective:To know the current situation of curriculum construction of "Fundamentals of Toxicology" of preventive medicine major in traditional Chinese medicine (TCM) universities.Methods:The undergraduates of preventive medicine major from TCM universities in whole China were selected as the research objects using the cluster sampling method, who took "Fundamentals of Toxicology" course in the 2019-2020 academic year. Questionnaires were compiled and analyzed using descriptive method and radar chart.Results:Six TCM universities were investigated in this study. According to the results, 83.09% (344/414) thought it was necessary to set up the "Fundamentals of Toxicology" course, and the main motivation was to deal with the examination. The agreement rate between the opening semester and the students' wishes was 59.90% (248/414), and the percentages of better satisfaction of theoretical course teaching content, selection of teaching materials and class time were 64.73% (268/414), 55.07% (228/414) and 59.90% (248/414) respectively. The satisfaction rate of experimental course setting, teaching effect and class time was 59.66% (247/414), 62.08% (257/414) and 58.21% (241/414) respectively. It was better to set five times [27.29% (113/414)] or four times [26.81% (111/414)], and four students in each group was the best [53.86% (223/414)]. The most interesting experiment project was bone marrow micronucleus test [29.21% (59/202)], and comprehensive design experiments and highly operable experimental projects should be added. The radar chart of the core knowledge was normal operation type, and there were some differences among students in different schools.Conclusion:There are some differences in the course setting and core knowledge mastery level of the "Fundamentals of Toxicology" course of preventive medicine major in TCM universities. It is necessary to optimize the curriculum construction from opening semester, textbook selection, teaching content, experimental project, etc.
