[Terminology investigation on "<i>Jingmai binghou</i>"].

"<i>Jingmai binghou</i>" (meridian symptoms) is not the original term in ancient works, and it is proposed in modern teaching materials of acupuncture. It refers to "the diseases caused by the invasion of pathogenic factors into meridians", and "diseases of the affected meridians", recorded in <i>jingmai</i> (<i>Meridian</i>) of <i>Lingshu</i> (<i>Miraculous Pivot</i>). The proposal of this term is related to the academic tendency of textbook writers and the influence of TCM policy in China. Through collating and analyzing the records of meridian disorders in ancient works, it is found that besides the classic "meridian symptoms", many <i>zangfu</i> disorders, the disorders along the running course of meridian based on meridian differentiation, collateral disorders and the disorders of the exterior-interior relationship of meridians should be classified as meridian disorder. In order to accurately express the rich content of "<i>Jingmai binghou</i>", from the perspective of terminology normalization, it is believed that the expression as "meridian-collateral dominated disease" may reflect its connotation more comprehensively.
