摘要Innovation springs from practice,and its soul lies in practical thinking.All human wisdom is a product of practice and needs to be tested during the practice.With the rapid development of medicine,a clinician has to keep pace with the new era,grasp the pulse of the times and innovate.Only in this way,could he or she lead the trend of the new era.Clinical medicine is a practical science and implemented mainly by clinicians,requiring them to explore the truth and pursue technological innovation all the time.At the same time,as an academic leader,a clinician is encouraged to practice actively,to take risks to innovate,to pursue truth and test truth in the practice,discarding old ideas and correcting wrong theories and technologies.To summarize,a clinician has to push forward practice-based innovation of theory and technology to keep up with the pace of the times.
