藏象学说视野下营卫系统的总体构建

The Overall Construction of the Nutrient-defense System from the Theroy of Visceral Manifestations

营卫系统包括宏观与微观两个部分,前者是指血脉、经脉形成的网状通道系统;后者是指玄府—络脉体系,即血络、络脉及其临近的玄府、皮腠,涵盖四肢百骸之微观系统,包括细小微结构和非结构化通道。从气血的生成、运行和转化全过程来看,脏腑、经络和营卫这三个部分,一脉相承,既有结构特征,也蕴含功能特色。营卫系统也是中医藏象学说中一个不可缺少的组成部分。营卫系统具有时空开阖性,神机互用是营卫系统与外界进行能量与信息的正常交感;营卫是气化的主要场所,三焦仅是气化的重要场所而不是全部。营卫失调包括气血亏虚不荣、气机郁滞不通、气化开阖不利三个层次的异常。

The nutrient-defense system includes macro and micro parts.The former refers to the reticular channel system formed by blood vessels and meridians;The latter is pore-collateral system.It specifically refers to the col laterals,blood collaterals and the adjacent pore,and the floating collaterals extend to the skin-texture.Covering the internal and external micro systems of limbs and bones.This system consists of two parts:unstructured channel,and micro structures extending from vessels-meridians.From the perspective of generation,operation and mutual transformation of Qi-blood,The human body can be divided into three parts:viscera,meridians and channels,and nutrient defense;It has both structural and functional features.The nutrient-defense system has the characteristics of opening and closing in space-time.The mind-mechanism interaction is the result of its interaction with external energy information.It is an indispensable part of the theory of visceral manifestations in TCM.The main place of Qi transformation is in the nutrient-defense.Triple energizer is only an important place for Qi transformation,not all of it.The disharmony of nutrientdefense includes three levels of abnormalities:deficiency of Qi and blood,Qi Stagnation Syndrome,and unfavorable of Qi transformation.
