Description
Technical field
The present invention relates to a kind of method of quality control, particularly be used for a kind of method of quality control for the treatment of the injection of apoplexy.
Background technology
Apoplexy belongs to modern medicine cerebrovascular disease category, is a kind of disease with higher incidence, case fatality rate and disability rate, be the elderly's common disease, and age of onset has the trend of rejuvenation.In apoplexy, the ratio of ishemic stroke is higher, and according to epidemiology survey, cerebrovascular disease 18% is cerebral hemorrhage, and 82% is cerebral infarction.Relevant survey data shows that the annual apoplexy incidence of disease of China is 115.8/10 ten thousand, and particularly dysnoesia behind the apoplexy and limbs are disabled, and have become serious social concern and difficult medical problem; Morbidity back in the patient of first aid survival, has 73%-86% hemiplegia to occur in 1 week, and 71%-77% has moving difficulty, 47% sitting alone, and 44% has the proprioception obstacle, and the disability rate of apoplexy is very high.It is generally acknowledged that acute stage alleviates the scope of brain tissue damage and degree is to reduce the important step of disability rate.
The clinical treatment of ishemic stroke, the traditional Chinese medical science mainly are square medicines such as application is calming the liver to stop the wind, eleminating phlegm and freeing channels, the promoting flow of qi and blood circulation, the inducing resuscitation of having one's ideas straightened out at present.Because the restriction of aspects such as method of administration is difficult to bring into play the treatment advantage in acute stage.Even some injections such as Mailuoning, QINGKAILING etc. are arranged, but because its complicated component, mechanism of action is not clear and definite as yet, and the purpose of clinical practice is relatively poor; Function of promoting blood circulation to disperse blood clots such as XUESHUANTONG (thromboembolism is logical) parenteral solution are better, but very little for causing the obstructed factor affecting of brain network stasis of blood resistance, clinical efficacy does not obtain to significantly improve.Doctor trained in Western medicine still has many insoluble problems according to the medicine and the therapeutic scheme of cerebral ischemia mechanism result of study initiative in recent years.For example, think the medicine nmda receptor antagonist (MK-801) that can stop the ischaemic damage process, calcium-ion channel antagonists (Nimodipine) etc. at present, can reduce the scope of ischemic pathology, but with making any distinction between the neurotransmission of blocking-up EAA mediation, influence some normal physiological functions, comprise and repair necessary neural plasticity, may bring adverse effect for the prognosis rehabilitation.The ischemic brain edema of acute stage is important pathologic process of apoplexy.Because the mixing of cytotoxicity and angiogenic two class factors, the former is at the depletion of film ionic pump, and treatment should take to reverse energy exhaustion promptly provides oxygenated blood to recover pumping function, and at this moment, the high osmotic agent effect is limited; The ischemic angiogenic oedema that blood-brain barrier collapse produces after a few hours, high osmotic agent should prove effective according to reason, however that CT scan is observed high osmotic agent is not remarkable to cerebral infarction swelling effect, and sweet mellow wine has the spinoff of concurrent oedema knock-on; As if the still difficult appraisal of dexamethasone curative effect on probation does not have benifit even steroid hormone is widely applied yet, even may be harmful to ischemic neuron; Glycerine has certain effect in the cerebrovascular disease survivor, but causes diabetes control difficulty.
Therefore, a kind of ischemic cascade reaction of preventing of clinical needs damages, and improves the slight irrigation stream mode of cerebral ischemia, thus effective neuroprotective cell, the relative clearly modern Chinese herbal medicine of effective substance compound injection with the mechanism of action.
