Description
Technical field
The present invention relates to health product and preparation method thereof field, particularly relate to a kind of compositions, its preparation method and the capsule containing said composition with auxiliary improvement of memory power function.
Background technology
In the modern life, people's hypomnesis phenomenon is general.The forgetful commonly encountered diseases becoming city professional population, forgetful is the common multiple disease of old people, especially with cerebral blood supply insufficiency cause forgetful the most common.Population of adolescent is mainly manifested in and has a poor memory, and majority is owing to depending on computer, books etc. unduly, and excessive mental pressure, often smokes and drink, and the bad living habit such as frequent breakfast skipping causes.
The aging of human brain just started from 30 year, more obvious to the aging of brain time over fifty years old.With advancing age, brain there occurs some senile brains and changes old people in various degree, and serious meeting generation brain atrophy, therefore there will be hypomnesis.In addition, as cerebrovascular class disease, the exogenous loss of brain, nervous lesion class medicine, in meals, some composition etc. can cause the decline of memory function equally.Middle-aged and elderly people encephalopathy symptom reaches an advanced stage and shows as ischemic dementia, presenile dementia (AD) more.
The patients of senile dementia of current the Asian-Pacific area has 1,400 ten thousand people, and may be increased to 6,500 ten thousand people to the year two thousand fifty, wherein 40% from China.There is old dementia patients about 5,000,000 in current China, comprise presenile dementia and AD and the vascular dementia caused by cerebrovascular disease, in addition we are about to enter aging society, and numerous middle-aged and elderly people mass-brain health status causes anxiety, and the burden brought to society will be also huge.
Vascular dementia---the energy metabolism impairment caused by chronic cerebral ischemia, glucose utilization reduces, albumen resulting anomaly, and neurotransmitter changes, cholinoceptor lacks, cerebral white matter damage and neuron loss constitute the pathophysiological basis that chronic cerebral ischemia causes cognitive function to damage, and drastically influence the quality of life of old people, belong to one of infirmities of age, therefore, how to improve chronic cerebral ischemia symptom, delay it and occur, develop, become the problem that clinician pays close attention to.Oxidative stress is the important mechanisms of cerebral ischemia, confirm, neurocyte is very responsive to oxygen free radical injury, free radical chain reactions, the neuron etc. of primary challenge grey matter is rich in the cerebral tissue of lipid, make neuronal death, especially it can make the not serious neuron of initial ischemic injuries necrose.Mitochondrion is that in cell, oxygen-derived free radicals produces maximum places, also more subjects to radical damage and causes memory function reduction.Modern study shows dull-witted front pathological changes, comprises cerebral infarction, vascular hypertension, cerebral arteriosclerosis etc.Zhao Nan is firm etc. thinks, after cerebrovascular, the emotions such as the irritability of patient are stronger because of the puzzlement of disease, certainly will cause autonomic nervous dysfunction, endocrine dysfunction is lacked of proper care, and sympathetic excitability increases, Secretion of Catecholamine increases, blood pressure raises, and blood glucose raises, thus promotes arteriosclerosis, cause hemorheological change, more increase the weight of the long-term hypoxic-ischemic of brain cell, finally make brain cell produce irreversible infringement, occur that hypomnesis even causes vascular dementia.
Presenile dementia---there is serious degeneration in the choline system of presenile dementia patient cortex, causes learning and memory impairment and cognitive disorder, produces dementia symptom.When presenile dementia occurs, the cholinergic neuron of basal forebrain areas is lost, and causes the synthesis of acetylcholine, storage, release to reduce, thus to cause remembering with recognition function obstacle be main clinical manifestation.Radical damage is one of major reason causing AD.The lipid peroxidation of free radical and initiation thereof participates in the destruction that neuronic infringement oxygen-derived free radicals can cause neuron and glial cell biomembrane and subcellular structure and function.The oxygen-derived free radicals of a large amount of generation can cause mitochondrion DHA and mitochondrial membrane damage, and mitochondrion DHA damage occurs relevant with AD.
After people in middle age, namely the function and structure of brain changes gradually, and neurocyte and nerve fiber all can occur degenerative change, and brain weight alleviates, and cerebral blood flow also reduces about 17% than at an early age.Modern medicine study finds, the brain of people has highly plastic and great potential.With advancing age, knowledge, experience can be more and more abundanter, thus faculty of understanding and language competence can be improved, make old people exceed youngster, the prevention so old brain health problem can be kept healthy to the analysis of problem, inductive reasoning and judgement.
The brain of people is the maincenter producing thinking and consciousness, metabolism is very vigorous, brain function normally carry out the participation needing multiple nutrients material, in addition, when carrying out mental activity, brain cell needs a large amount of oxidations, if oxygen deficiency will affect the function and thinking of brain, if therefore memory to be improved normally can be run by supplementary brain necessary material, increase brain cell to the utilization of oxygen and supplementaryly can promote that the approach such as the material that brain metabolism product is got rid of realize.
Supplement nutrition brain key, refreshing machine is nourished, and brain siddhi can be normal.By improving cerebral cortex blood flow, making chronic cerebral ischemia anaerobic condition be improved, lowering the injury that the emergency reaction of brain causes, alleviating the damage of cerebral tissue, lower damage and apoptosis that brain nervous cell causes because of hypoxic-ischemic.
The principal item of the health food of auxiliary improvement of memory power in the market has: lipid, protein and amino acids, mineral and microelement kind, vitamins, Chinese herbal medicine class.US healthcare food association expert identification has the composition that memory is improved effect: five hydroxytryptamine mixture, antioxidant, novel Chroma-Pak, ginkgo agent, huperzine A, w-3 fatty acid, Phosphatidylserine, Herba Catharanthi Rosei extract.
Now, along with the development of era of knowledge-driven economy, about mankind's brain research brain health problem has become the focus of World Developed Countries concern.The U.S. proposes " brain 10 years ", the slogan that Japan's proposition " understands brain, protection brain, creation brain ", and Japanese brain research association proposes brain research to disclose brain function, overcome disease of brain and to develop artificial intelligence for pillar.The relevant authoritative department of China is also proposed the brand new ideas of " in preventing brain overworked, valuing brain health " to society.But the new results that existing market responds this theory are not satisfactory, especially the field comprehensively paying close attention to brain health in health diet is also very limited, majority controls disease with regard to disease, single goes solution auxiliary treatment disease of brain symptom, and the importance that comprehensive brain health care, brain nutrition aspect do not go response to prevent from basis, certainly relevant technical products service is also limited.
The technical scheme that the present invention solves, on the one hand for the construction of domestic brain health idea is done one's bit, also can bring glad tidings for the brain health of vast middle-aged and elderly people on the other hand, also can go out high economic benefit for social creativity simultaneously.
