浅析中风之“外风”学说

Analysis of"External Wind"Theory in Treatment of Stroke

“外风”学说源于《黄帝内经》,在唐宋以前为中风的主要病机理论,可被概括为“内虚邪中”,即在机体营卫、脉络、气血、脏腑虚弱等内因的基础上,风邪、寒邪等外邪趁虚中人而引发中风。“外风”学说自金元时期开始衰落,并逐渐被忽视。根据《黄帝内经》《伤寒杂病论》《诸病源候论》和《千金要方》等中医经典对“外风”学说的详细阐述,以及小续命汤对于中风的确切疗效,和寒冷刺激、感染等外在因素引发、加重中风的现代研究证实,“外风”说对于中风的临床防治尤其是精准预防仍有意义。建立基于“外风”学说的中风预警模型,或可为中风的精准预防提供更全面的参考。

The theory of"External Wind"is originated from Huang Di Nei Jing,which was the main pathogenesis theory of stroke before the Tang and Song dynasties.It can be summarized as"internal deficiency and outside evil factor injury",that is,on the basis of internal weakness such as Ying Qi,Wei Qi,meridians,Qi and blood as well as Zang and Fu organ weakness,external evil factors such as Wind and Cold take advantage of the deficiency in human body to cause stroke.The theory of"External Wind""began to decline during the Jin and Yuan dynasties and gradually became overlooked.According to the detailed explanation of the theory of"External Wind"in traditional Chinese medicine classics such as Huang Di Nei Jing,Shang Han Za Bing Lun,Zhu Bing Yuan Hou Lun,and Qian Jin Yao Fang",as well as the precise therapeutic effect of Xiao Xuming Decoction on stroke and modern research on external factors such as cold stimulation and infection that cause and worsen stroke,the theory of"External Wind"still has significance for clinical prevention and treatment of stroke,especially the precise prevention of it.Establishing a stroke warning model based on the theory of"External Wind"may provide a more comprehensive reference for precise prevention of stroke.
