[State-regulating medicine: an integration of traditional Chinese medicine and biomedicine].

Currently available drugs for complex diseases have such limitations as unsatisfactory efficacy, drug resistance, and toxic side effects. Complexity of biological systems is a determinant of drug efficacy. It is not an effective approach to find disturbance strategies for the complicated biological network for complex diseases based on the static topological structures, as biological systems undergo dynamic changes all the time. Supported by profound theoretical basis and rich clinical experience, traditional Chinese medicine(TCM) emphasizes systematic and dynamic treatment depending on changes. Guided by TCM theory in practical treatment, Chinese medicine dynamically and comprehensively regulates the overall state. Therefore, if the dynamic factors are taken into consideration in design, the resultant drugs will be more effective. This study proposes state-regulating(SR) medicine from the perspective of system dynamics, elaborating the concept in terms of the connotations and principle and verifying the feasibility of SR medicine design with the attractor method. Thus, SR medicine is a new concept for drug discovery and design from the aspect of system dynamics, which integrates the TCM focusing on holistic dynamic regulation with biomedicine that features local microscopic research such as molecular mechanisms. The attractor method is a feasible techinical way for SR medicine design.
