Theoretic Research On The Etiology And Pathogenesis Of Yin Deficiency With Yang Hyperactivity Pattern Of Stroke

Objective:Stroke is a high incidence disease which seriously affects the health of the middle-aged and elderly at the present. As its etiology and pathogenesis is complex and its abrupt onset, high disability and lethality rate, ancient physicians have proposed the concept that prevention is greater than cure. Ye Tianshi put forward that yin deficiency with yang hyperactivity can lead to stroke in his book called "A guide to clinical practice with medical record. " This idea makes a great difference to theoretical research and clinical practice about stroke afterwards. this paper arranged the discourse about the yin-deficiency and yang-excess syndrome of stroke from Pre Qin period to Ming and Qing dynasties and it first investigate the theory source and course of the yin-deficiency and yang-excess syndrome of stroke. Mean while, the possible etiology and pathogenesis characteristics of the yin deficiency and yang excess syndrome of stroke are summarized and analyzed in the paper。 Furthermore, this paper paid attention to the literature research of yin deficiency constitution and explored its influence on yin deficiency and yang hyperactivity pattern of stroke in order to provide a reliable theoretical basis for clinical stroke prevention.Result:1.As far back as Pre Qin dynasty, Huangdi’s internal classic has mentioned that the course of stroke was related to liver and kidney. this period is the seeds of the theory about the yin deficiency and yang excess syndrome of stroke. the Han and Tang period is the foundation of the stroke theory when open the river of stroke etiology. The Song, Jin and Yuan dynasties, represented by Jinyuan three masters noticed that the cause of stroke was associated with the congenital essence of deficiency of liver and kidney. although this period not took the yin-deficiency and yang-excess as the main pathogenesis, the pathogenesis and related causes of the yin-deficiency and yang-excess syndrome of stroke began to take shape. in the Ming and Qing Dynasties, the theory entered into mature stage when mainly focuses on 3 doctors of Zhang Jingyue, Zhao Xianke, Ye Tianshi.2. The formation and the related record of the yin-deficiency and yang-excess syndrome of stroke theory are mainly in clinical cases, and then gradually enrich its theory; the yin-deficiency and yang excess syndrome of stroke has long duration and abrupt onset. because of liver and kidney yin deficiency has low onset. hyperactivity of liver yang is this syndrome’s standard. if not to prevent and control the syndrome, while exhaustion of kidney yin deficiency, liver yang acute heat excess due to stroke.3.The etiology of the yin-deficiency and yang-excess syndrome of stroke are related to excesses of drink and sex, five extreme change of emotiom, be worn with age, environment, improper diet, internal exhaustion, etc. multiple pathogenic factors lead to liver and kidney yin deficiency. the etiology not only is the risk factors, but also is the pathogenic factors. the prevention of The etiology of the yin-deficiency and yang-excess syndrome of stroke should from the cause.4.The prevention recommadation to the susceptibily population: to prevent stroke to be noticed that sexual intercourse should be moderate, keep the emotions comfortable, diet, timetable regular. At length, the one overwork, old and frail should take more attention.
