The traditional Chinese medicine consider the seven motions(happiness,anger，riment,thoughtfulnes，sadness，horrorand fright)as external expression of human psychomotilit yinnormal situation However。if psychological stimulation is too strong or lasts too long，leading the emotion over excited odepressed，it may cause maladj ustment of yirryang，disharmony of qi and blood，isfunction of zang-fu，finallv diseases happen．The traditional Chinese medicine always attach importance to the combination of psvchotherapeutic technique and acupuncture therapy，also to eliminate negative psychologic factors before and during the cure．There is a sentence in Huangdi Neijing(《黄帝内经》)which means that active psychology is favourable to recovery，contrarily，negative psychology goes against recovery．Therefore，only whendoctors cure people’s psychological problems and cure diseases with acupuncture at the same time can curative effect be satisfactory，leading to harmony of five zangand relative equilibriumof yirvyang.
There are many theories about howpsychologic factors affect disease processes in modern medicine．The one which has been accepted by most people is the stress theory，advanced by Canadian physiologist Selye．He points out that strong psychologic stimulation such as depression，tension，horror and anger，etc．may cause a series of neuroendocrine reaction in human body，mostly excite the sympathetic nerve，release catecholamine，increase secretion of cortin and anterior pituitary hormone，decrease secretion of insulin．The reaction mentioned above would cause all kinds of malfunction and decompensation．For examples，the excitement of sympathetic nerve may accelerate heartbeat，constrict capillary vessel，boost blood pressure；over constriction of capillary vessel may lead to mierocirculation ischemia；blood insufficiency to important viscera may cause incompetence and injury of tissue；over secretion of cortin may stimulate the secretion of stomach acid，cause gastric and duodenal ulcer．On the contrary，euphoric and balanced psychology harmonizes activities of organs and systems in human body．For example，secretion of cortinis sufficient；the whole endocrine systemis in a steady balanced state；the competence of immune systemand metabolism are strengthened．Consequently，human body would be capable to resist pathogenic microorganisms’aggression and rehabilitate injury of tissue，which is good for curing diseases．
