RESUMEN
Although Yin-Yang Wu-Xing (Yin-Yang and Five-Elements, subsystems of human body) has been the theoretical basis of traditional Chinese medicine (TCM) for more than 5 000 years, it has been primarily analytical or empirical in nature without a formal scientific foundation. Based on bipolar set theory, an equilibrium/non-equilibrium computational model of Yin-Yang Wu-Xing is proposed. The Yin-Yang Wu-Xing dynamical systems are formulated so that equilibrium and non-equilibrium conditions can be established and proved. Computer simulations of equilibrium and non-equilibrium processes show that this new approach can provide diagnostic decision support in TCM. Thus, this equilibrium-based approach provides a unique scientific basis for future research in TCM, Qi (vital energy), QiGong, Meridians and Collaterals (acupuncture channels) and herbal treatment. On the other hand, it provides a basic Yin-Yang cellular network architecture for modem scientific research in genomics such that regulation mechanisms of the ubiquitous YY1 protein for cell processes can be explained.
