More than 2,000 years ago,traditional Chinese medicine proposed"dialectical treatment","same disease and different treatment,and different diseases with the same treatment",which is a statement of precision medicine on the philosophical level.In the 1970s,the concept of"personalized treatment"was proposed;in 2011,the American Academy of Medical Sciences published"Towards Precision Medicine";in January 2015,the US government proposed"precise medical treatment".Precision medicine is the objective necessity of the development of medicine itself,and it is the public's health demand.
