Risk factors and prevention strategies of spinal cord ischemic injury after thoracoabdominal aortic aneurysm repair / 中华胸心血管外科杂志

Thoracic and abdominal aortic aneurysm repair has always been a challenging procedure in cardiovascular surgery due to its high mortality and complication rate. At present, there are traditional open surgery, hybrid surgery and intracavitary repair for thoracic and abdominal aortic aneurysms. The main postoperative complication of spinal cord ischemia injury is paraplegia, which seriously affects the long-term survival rate and quality of life of patients. This paper summarized and considered the pathogenesis, risk factors and prevention measures of spinal cord ischemia injury after thoracic and abdominal aortic aneurysm repair.

Application of flipped classroom based on WeChat and TBL in basic surgery teaching / 中华医学教育探索杂志

There are many problems existing in the basic teaching of traditional surgery, such as much more content, difficult operation, fewer learning hours, more passive acceptance while less active learning and so on. Flipped class based on the WeChat and team-based learning (TBL) is based on the on-line and off-line class. We can use WeChat group and subscription to issue relevant learning materials, learning tasks and test before class. Also, we can summarize and explain incisively by discussion after field operation in class, and answer and test in the way of WeChat discussion after class. Finally, the three-dimensional hybrid teaching will be condensed and sublimated by brand competition based on the basis of surgery, achieving knowledge transfer before class, knowledge internalization in class, knowledge consolida-tion after class and brand competition sublimation, in order to improve the teaching effect of surgical basis.
