从玄府理论探讨中风的外风学说

The Exploration of the Theory of Exterior Wind of Stroke and the Treatment from Xuan Fu Theory

"风"是中风的发病原因,可由外入,亦可由内而生。唐宋之前认为中风为内虚外受风邪所致,多采用扶正祛邪方法治疗,续命汤系列是治疗中风的代表方剂。但由于中风患者的特异性表现与感受风寒邪气迥异,故宋代之后医家多持内风说,而外风说渐不为人知,临床应用亦大受限制。后世刘河间充分发挥了《黄帝内经》玄府理论,认为玄府属微细窍道,存在于身体内外上下,是气机升降出入之通道。玄府闭塞,气机升降失常,可导致人之五官失灵,意识不用,颇类中风表现,为从玄府理论探讨中风提供了理论依据。

＂ Wind＂ is the cause of stroke. This wind not only comes from exterior,but also from interior. Before the Tang and Song dynasty physicians believed that the pathogen of stroke were interior weak and wind evil attacking exterior. Therefore,they commonly treated the disease by expelling wind and removing cold. And then,life soup series was the representative prescriptions.However,the characteristic manifestations of stroke is different from the feeling of cold evil. After the Song dynasty,physicians held more internal wind. The theory of exterior wind was unknown by doctors and the clinical application was greatly restricted. Later generations of the Liu Hejian gave full play to Huangdi Neijing（ the Yellow Emperor＇s Canon of Internal Medicine） Xuanfu theory,believing that the Xuanfu was a tiny trick that exists both inside and outside the body. It was the channal for functional activities of Qi. Xuanfu occlusion and abnormal gas turbine movements may lead to the five sense organs out of action and unconsciousness,similarly to analogous apoplexy performance,which will provide the base for exploring stroke with the theory of Xuanfu.
