- Abstract: The concept of amplification feedback pathways represents an intersection between electronics and control theory,involving both amplification and feedback processes.It reveals the dynamic evolution mechanisms of systems under the combined influence of these two processes.In Traditional Chinese Medicine(TCM),Chest Bi syndrome is considered a"ben xu biao shi"condition,with its primary pathology located in the heart and closely related to other organs such as the liver,spleen and kidneys.This article focuses on the interrelationship between organ dysfunction and the imbalance of the Five Elements Theory.By applying amplification feedback theory and models,the study constructs and analyzes single-stage amplification feedback pathways involving the heart,liver and kidneys,as well as double-stage amplification feedback pathways involving the heart,liver,kidneys and spleen,in the context of multifactorial interactions such as heart and kidney Yang deficiency,Qi stagnation in the heart and chest,and spleen-stomach dysfunction.Particular emphasis is placed on analyzing the phenomena of deep feedback and self-excited oscillation,and specific formulas and clinical evidence are used to validate the analysis results,clarifying the role of relevant organ function changes in the pathogenesis of Chest Bi syndrome.The article aims to provide new insights into the complex pathogenesis of refractory diseases from a control theory perspective,offering new directions for modernizing TCM research with digital technology and theoretical support for future simulation-based digital systems guided by TCM theory.
