在中医理论体系中，气的升降出入是阐释脏腑功能运行的核心机制。神阙穴位于任脉，天枢穴隶属足阳明胃经，命门穴处于督脉，三穴虽分属不同经脉，但其体表投影位于腰腹部同一水平面，前后对应、左右对称，在空间结构与功能属性上呈现出明显的协同性。基于对相关经典文献的系统梳理，本文从气运行的空间结构特征入手，结合整体观念，对神阙-天枢-命门这一同水平腧穴群在气之运化中的作用进行综述性分析，认为其在调控三焦气升降出入及气化归藏过程中具有枢纽意义，共同构成腰腹部一个重要的气机调控界面。

Within the theoretical framework of traditional Chinese medicine(TCM),the ascending,descending,exiting,and entering movements of qi constitute a core mechanism for interpreting functional activity of the zang-fu organs. Shenque(CV8) belongs to the conception vessel,Tianshu(ST25) pertains to the foot yangming stomach meridian,and Mingmen(GV4) is located on the governor vessel. Although these acupoints are located in different meridians,their body surface projections are situated on the same horizontal plane of the waist-abdominal region showing anteriorposterior correspondence and left-right symmetry. This spatial arrangement suggests a notable degree of coordination in both structural location and functional significance. Based on a systematic review of relevant classical medical literature,this paper examines the role of the Shenque-Tianshu-Mingmen acupoint group in the movement and transformation of qi from the perspective of its spatial structure and in light of the TCM holistic view. It is proposed that this horizontally aligned acupoint interface serves as a pivotal regulatory hub in coordinating the ascending,descending,exiting,and entering movements of qi across the triple energizers,as well as in the processes of qi transformation and re-storage. Collectively,these acupoints form an important functional interface for the regulation of qi movement in the waist-abdominal region.
