活血化瘀法防治脑缺血损伤的理论探讨

Academic discussion on promoting blood circulation for removing blood stasis method preventing and treating cerebral ischemic (CI) injury

文章论述瘀阻脑络为缺血性中风的病机关键,探讨脑缺血发生后由于局部瘀塞不通进一步派生"痰(饮)、风热、瘀毒"等多种病理产物,导致脑缺血后炎性损伤,形成"炎症—血栓"的恶性循环,使脑神经细胞缺血缺氧、损伤加重,甚至成为不可逆的脑缺血坏死,是病情发展演变与恶化加重的根源,故在治疗上采用活血化瘀大法,可使瘀阻得通,风火得清,痰饮得平,而肿毒自消,并可改善脑部的炎症、损伤、微循环障碍的病理状态,使脑脉通畅,血供恢复,减轻或改善神经功能的缺损症状,从而有效降低病残率与病死率。

This thesis discourse upon blood stagnant in cerebral venation is the pivotal pathogenesis of cerebral ischemia stroke,and discuss once the cerebral ischemia occur,it can derive more phlegms,toxic heat and other pathological outcomes,resulting in inflammatory injury of cerebral ischemia,forming a vicious circle of ＂inflammation-thrombus＂,so that aggravating the injury with ischemia and anoxia of never cells,even causing inreversible putrescence of cerebral ischemia.And this condition should be the springs of the development and aggravation of the illness.Therefore,applying promoting blood circulation for removing blood stasis measures can removing blood stasis,eliminating pathogenic wind-fire and cleanning out phlegm,so the pyogenic infections can be dispelled,and the pathological state of inflammation,injury and microcirculation obstacle in the brain can be meliorated.Then,the brain vascula become smooth and the blood supply resume,the symptoms with never functional impairment alleviate or meliorate,thereby,the rate of death and cripple decrease obviously.
