Objective:To explore the effect of introducing mixed reality technology into traditional atlas teaching to teach airway anatomy under bronchoscopy.Methods:A total of 30 Batch 2017 fifth-year clinical medicine students from Shanghai Jiao Tong University School of Medicine were randomly divided into control group and test group by RAND function in Excel, with 15 students in each group. The control group was taught with the traditional bronchoscopic atlas teaching, and the test group was combined with mixed reality technology. The two groups had the same class time. After teaching, the teaching effect was evaluated by examination and evaluation questionnaire. SPSS 25.0 software was conducted for t test and Mann-Whitney U test. Results:The average score after teaching of test group was (61.67±20.15), and that of control group was (36.67±13.32), with statistically significant differences ( t=4.01, P<0.001). According to the questionnaire results, the scores of the test group on course understanding, course concentration, participation, mastery and satisfaction were better than those of the control group, and the differences were statistically significant ( P<0.05). Conclusion:Using mixed reality technology to assist the clinical teaching of airway anatomy under bronchoscopy can improve the quality of students' study and enhance their understanding of the teaching content and students' participation passion, achieving better teaching effect.

The detection of peripheral pulmonary lesions has increased gradually with the popularity of CT. Rapid and accurate diagnosis, and individualized treatment are two aspects we need to pay great attention to. These situations also raise higher request for the technique in diagnosis and treatment. At present, the commonly used transthoracic methods can increase the risk of complications such as pneumothorax and bleeding. The newly bronchoscopic approaches for diagnosis and treatment make less injury via natural lumen and have been applied widely in clinics. This review will introduce the worth expecting progress in bronchoscopic diagnosis and treatment for peripheral pulmonary lesions.
