The notions of Evidence-based medicine developed through two phases, which successively looked into the doctor-patient relationship and decision-making background. One of the new trends in evidence-based medicine deals with how to make theory into practice. Applying the practical model from post-SSK to interpret how the notions of evidence-based medicine changed, it is found that evidence-based medicine is an indivisible practical network integrating many natural and social factors as well as material and cultural factors which interconnect through "translation". Therefore, the involvement of various factors such as natural matter, social relations, regional factors, resources of traditional culture and scientific instruments leads up to the ultimate theory becoming the result of multiple factors in a continuous process of seeking the best way in scientific practice. In this motile process, the borderline between nature and society, material and human, natural science and social science vanishes and a new stage called humanistic medicine appears.
