Objective:To investigate the effects of micro course in teaching of thoracic surgery.Methods:According to the teaching content of thoracic surgery and the previous teaching experience of the Department of Thoracic Surgery, the micro learning resource base with characteristics was established. We enrolled 20 students of Grade 2014 as the experimental group and 20 students of Grade 2013 as the control group. The micro learning resource base was used for teaching in the experimental group, and the traditional course teaching was carried out in the control group (the teachers were not changed). The teaching effect was evaluated through questionnaires and examinations.Results:The micro learning resource base of thoracic surgery consisted of 11 modules. The learning interest, effect and acceptance in the experimental group were significantly higher than those in the control group (all P<0.05), and there was no significant difference in understanding ability ( P>0.05). Moreover, the experimental group revealed much higher scores in the basic knowledge [(85.3±10.6) vs. (72.5±9.6)] and clinical ability [(87.3±11.5) vs. (75.9±12.2)] than the control group (both P<0.05). Conclusion:It is worth popularizing to establish a micro learning resource base and teaching application model suitable for thoracic surgery, which can help improve students' interest in learning and achieve better learning results through students' targeted and active learning.

Strengthening the construction of traditional Chinese medicine （TCM） discourse system for international audiences is necessary for enhancing cultural soft power， accelerating the construction of trade power， integrating into the global healthcare system， and realizing international scientific and technological dialogues.TCM not only garners widespread attention from the international community but also faces numerous challenges. The external discourse of TCM has fallen into difficulties， including blocked channels of expression， lack of a discourse subject， contextual segregation of discourse， and a narrative information flow deficit. Based on this， realistic approaches to breaking through dilemmas are proposed from four dimensions， that is， strengthening the construction of international standards for TCM to increase its recognition overseas， improving the development of international talent teams to enhance the visibility of TCM abroad， expanding the construction of the TCM service trade system to deepen its contribution overseas， and enhancing the efficacy of international communication of TCM to strengthen its reputation abroad.
