Background technology
(generalized anxiety disorder GAD) as the clinical commonly encountered diseases of psychiatric department, frequently-occurring disease, is serious harm human physical and mental health's a spirit type illness to generalized anxiety disorder.According to " Chinese mental disorder classification with the diagnostic criteria third edition " criteria for classification (CCMD-3), primary disease panic disorder normal and acute attack closes and is called anxiety neurosis, but is its topmost form of expression with GAD in clinical.Modern clinical research shows that GAD patient's clinical symptoms is various, pathogeny is complicated, and primary disease is the chronic course of disease more and is prone to recurrence; Symptom is delayed repeatedly, and is associated with many physical diseases, also sick altogether depressed and other anxiety disorders of the patient of significant proportion; The patient not only exists and is difficult to the psychic pain of standing and can't break away from; Severe patient can cause social function impaired, even occurs committing suiside, and causes serious spirit and financial burden for individual, family, society.Therefore, carrying out effective study on prevention of GAD and be not only great public health problem, also is comparatively outstanding social problem, has become the problem that society and medical circle are widely paid close attention to.
With regard to the clinical characters of disease, GAD is a core symptom with the spirituality anxiety, mainly shows as the frightened or on tenterhooks of frequent or lasting no clear and definite object or immobilized substance, and its nervous degree with worry does not conform to actual environment very much, but is difficult to automatic control.In addition; Normal performance with somatic anxiety; Mainly be that autonomic nervous function hyperfunction (more common with respiratory system, cardiovascular system, nervous system, genitourinary system and skin heart reaction symptom) and motion are uneasy, also there are cognitive dysfunction such as attention, memory, execution function in the patient who has.
GAD is the modern medicine name of disease, though Chinese medicine does not have this name of disease, with regard to its cause of disease and clinical manifestation, belongs to feelings will disease category more.According to the different manifestations of its primary symptom, can it be belonged in a plurality of disease of tcm such as " epilepsy ", " lantern disease ", " being insomnia ", " hysteria ", " Bulbus Lilii syndrome ", " globus hystericus ".Because the GAD clinical symptoms is various, pathogeny is complicated; Sum up the tame argumentation to the GAD etiology and pathogenesis of traditional Chinese medical science doctor and roughly can reduce the case of a physically strong patient running a high fever, deficient syndrome and three aspects of simulataneous insufficiency and excessive, wherein most families that cure tend to think that the outbreak of GAD is its basic pathogenesis with pathogenic fire derived from stagnation of liver-QI.
At present, the treatment of GAD mainly is that medicine is main, especially Western medicine; Although structure novel anxiolytic thing different, various in style continues to bring out, for the treatment of GAD provides different selections, in the treatment of generalized anxiety disorder; The past first-selected benzodiazepine medicine (BZD); Its obvious effective rate is 41%~59%, but it has side effect such as addiction property, drug resistance and withdrawal symptom, is prone to cause iatrogenic addiction with BZD treatment generalized anxiety disorder.And the Western medicine that is usually used in treating GAD at present has buspirone, alprazolam and paroxetine hydrochloride etc.; Can be used for treatment with patients such as slightly depressed generalized anxiety disorder (GAD), depressions; The addiction property of no benzodiazepine medicine and drug resistance; But have mostly that onset is slow, grow the course of treatment, cost an arm and a leg, the toxic and side effects of medicine, cause problems such as untoward reaction, untoward reaction is mainly dizziness, insomnia, xerostomia, feels sick, perspiration, constipation, blurred vision etc. are seen more.In addition, anxiolytic drugs is often to certain single link effect mostly, and the treatment spectrum of disease is narrow; In the face of the multiformity of patient's clinical symptoms, pathogenetic complexity often is difficult to obtain satisfactory effect; Cause patient's compliance relatively poor, limited the application of this type medicine to a certain extent.Aspect treatment by Chinese herbs, there have been some correlational studyes, but, caused the effective percentage of medicine low owing to select the limitation of medical material and the science limitation of prescription for use, therefore many patients also can't reach satisfied curative effect.
The present invention is based on the principle of organic conception and determination of treatment based on pathogenesis obtained through differentiation of symptoms and signs, is characteristic with the individualized treatment, has proposed this kind Chinese medicine composition, and it has the motility of principle-method-recipe-medicines and the safety of drug effect.To its clinical symptoms multiformity, pathogenetic complexity; Chinese medicine composition of the present invention can launch treatment from many target spots, too many levels, multipath; In clinical practice, have rapid-action, determined curative effect, patient's compliance is good; Can obviously improve the advantage such as generation and development of GAD patient's condition, have broad clinical application prospect.
