RESUMO
Objective:To explore the application value of case three-dimensional teaching method combined with standardized patient (CTTM+SP) in the clinical clerkship teaching reform of gastrointestinal surgery.Methods:A total of 120 students of clinical medicine having clerkship in Binzhou Medical University Hospital were recruited in this study, and they were randomized to the experimental group and the control group, with 60 students in each group. The experimental group took the CTTM+SP teaching method, and the control group adopted the lecture-based learning teaching method. The comprehensive ability of the two groups was evaluated by department graduation examination and satisfaction survey.Results:The examination performance and the satisfaction rate of students in the experimental group were significantly higher than those of the control group ( P < 0.05). Conclusion:CTTM+SP teaching method is helpful for the probationers to master the theoretical knowledge of gastrointestinal surgery systematically, improve the clinical thinking ability and the ability to solve practical problems, mobilize the students' learning motivation and interest, and improve the teaching effect of gastrointestinal surgery clinical clerkship.
RESUMO
Objective:To explore the efficacy of Ortho-Bridger System (OBS) for the treatment of complex tibial fractures.Methods:A retrospective study was conducted of the 64 patients with complex tibial fracture who had been treated at Department of Orthopaedics, Tongling People's Hospital from June 2014 to June 2018 using OBS. They were 46 males and 18 females, aged from 22 to 65 years (average, 44.3 years). There were 38 close comminuted or multi-segmental fractures complicated with skin and soft tissue defects and 26 cases of tibial exposure. The interval from injury to surgery ranged from 3 to 20 days (average, 13.6 days). The therapeutic outcomes were evaluated in terms of fracture union time, healing of skin and soft tissue defects and postoperative functional recovery.Results:The 64 patients were followed up for 12 to 50 months (average, 26.3 months). Obvious callus formation started at 3 to 8 months after operation and bony union was achieved at 9 to 18 months after operation. No obvious limitation was observed in the range of motion of the ankle and knee joints. Skin defects healed and completely covered the bone at 3 to 6 weeks after operation.Conclusion:OBS can lead to fine clinical efficacy in the treatment of complex tibial fractures, like open and comminuted multi-segmental ones complicated with soft tissue defects.
