ABSTRACT
Based on the traditional medical theory,the theory of"ear-brain-liver-spleen correlation"was proposed by linking the ear with the brain,liver and spleen.Then,by combining the Chinese medical etiology of Functional Dyspepsia(FD)and the corresponding modern medical mechanism,we realized that the close connection between the ear,brain,liver and spleen is the theoretical basis for treating FD from the ear.In recent years,a new type of vagus nerve stimulation therapy,auricular concha eletro-acupuncture(ACEA),has been developed to treat FD by regulating the liver and spleen through the regulation of the brain,relieving liver depression and strengthening spleen and qi,thus treating FD.In terms of modern medicine,this is related to its ability to reduce anxiety and depression,reduce pain perception,enhance gastrointestinal motility and reduce central and peripheral inflammation by regulating the activity of the corresponding brain functional areas.By exploring the application of auricular concha eletro-acupuncture in FD on the basis of the"ear-brain-liver-spleen correlation",we will better understand the unique role of auricular stimulation in regulating the brain and the blood of the liver and spleen,and promote the inheritance,innovation and development of TCM theory.
