下肢动脉硬化性闭塞症的五期衍化及辨治OACSTPCD

The network of Qi flow is composed of Qi Fu,the main pipe of Wei Qi and trachea,while blood Fu,Rong blood pipe and blood vessel constitute the system of blood flow.The aacting of the trachea and the quietness of the blood vessels are two states of Yin and Yang of the pulse.The pathogenesis of lower extremity arteriosclerotic obliterans is divided into five stages.First,Wind-Cold inva-sion from outside is the primary source of the disease,and the pathogenesis of this stage is Wind-Cold disturbing the Wei Qi and chill-ing stagnation in collaterals.Secondly,Cold attack induced Wei Qi injury is the cause of progress,and the pathogenesis of this stage is characterized by evil factor overactivity induced Wei Qi injury,or Cold injuring Wei Yang.Thirdly,Ying blood stagnation in meridian is the core of internal injury.The pathogenesis of this stage is Wei Qi failure and Ying blood injury and the result of blood stasis stopping in meridians.Fourthly,Heat burning and Yin deficiency is the focal point of the lesion,and the pathogenesis of this stage is character-ized by Ying blood stasis generated Heat,which burns in meridians and injuries body Fluid;Finally,Toxin stagnation induced meridian collapse is the ultimate result,and the pathogenesis of this stage is characterized by the burnt Fluid induced toxin and the exhaustion of meridian and Yin.These five stages of development are related to Qi and blood in general sense as well as the main pipe of Ying blood and Wei Qi,especially in the nuclear stage of internal injury,Ying blood stasis in meridians is the turning point of the pathogenesis.Therefore,in treatment,it is advocated to regulate Ying and Wei function of restoring and enriching the health,supplementing Qi and filling Ying to smooth the meridians,and then cut off the course of the disease and turn the crisis into peace.Through regulating Qi,re-storing Wei Qi,strengthening Ying blood and harmonizing meridians,the purpose of deficiency clearing,Qi smoothing as well as Ying blood and Wei Qi communication and balance is finally achieved.
