Description
Technical field
The present invention relates to a kind of Halth-care compositions for improving sleep, belong to technical field of health care food.The composition is logical
Cross improvement sleep, effectively prevention senile dementia.
Technical background
A Ercihai Summerside sick (Alzheimer ' s Disease, abbreviation AD) is called senile dementia, is worldwide the elderly
Common disease, it is estimated that, the whole world there are about 17,000,000~25,000,000 people to suffer from this disease.Domestic statistics show China 60 years old with
On the elderly in the disease incidence of this disease be about 0.21%, over-65s 0.31%.It brings huge warp to family and society
Ji and nursing burden, account for the 4th of human death's reason.Senile dementia is a kind of central nervous system degeneration, and clinic is main
Show as the neuropsychic symptoms such as gradual memory obstacle, cognition dysfunction, personality change and aphasis, feature venereal disease
Reason is changed into amyloid beta and is deposited in the nerve cell that the extracellular senile plaque to be formed and Protein tau Hyperphosphorylationof are formed
Neurofibrillary tangles and neuron loss are with glial cells hyperplasia etc..
The pathogenesis of senile dementia is not yet clear so far.But there are many theories for its pathogenesis, such as: beta-amyloyd egg
White (A β) theory, Protein tau Hyperphosphorylationof theory etc..(1) under normal circumstances, brain and cerebrospinal fluid (cerebrospinal
Fluid, CSF) A β can be discharged, but burst size is few and is conducive to remove, and works as sleep insufficiency, when neuron is damaged,
Soluble A β burst size is excessive, and removes that dynamics is inadequate, and soluble aβ protein, which will be deposited slowly, becomes rubbish, and assembles
As A beta, and then induce senile dementia.(2) Tau albumen is the highest microtubule associated protein of content, after Hyperphosphorylationof
It will lead to cell skeleton loss of function, destroy neuronal microtubules structure, cranial nerve retrogression pathological changes are caused, so as to cause old
Dementia.
The drug of existing prevention senile dementia is also very much, for example, disclosed in CN201510162432.7 it is a kind of treat it is old
The Chinese medicine composition of dementia, for another example a kind of nutrient oatmeal for preventing senile dementia of CN201310299893.X and its preparation side
A kind of folium ginkgo health product for preventing senile dementia of method, CN201210586523.X and preparation method thereof etc., but it is existing
These compositions or health care product, effect is undesirable, and tracing it to its cause may be not from the pathogenesis of senile dementia
It is basic to go to solve.
Summary of the invention
The present invention will provide a kind of Halth-care composition for improving sleep, by improving sleep realization to the morning of senile dementia
Phase prevention.
From amyloid beta (A β) theory, discovery improves sleep or A β can be improved in increase deep sleep (REM) time
Clearance rate；
From Protein tau Hyperphosphorylationof theory, it is found that when obstacle occur in AD patient sleeps, many sleep regulation regions (such as it is blue
Spot, nuclei of median raphe, nodular nipple nucleus, parabrachial nuclei and basal forebrain) in there is abnormal Protein tau phosphorylation, disclose sleep barrier
Hinder closely related with Protein tau phosphorylation namely related with senile dementia.
Speculate by improve sleep health can early intervention or mitigate AD morbidity effective means.
The present invention adopts the following technical scheme that:
A kind of Halth-care composition improving sleep, is grouped as: 25-40 parts of Walnut extract, gingko by the group of following parts by weight
22-45 parts of extract, 3-15 parts of Radix Pseudostellariae extract, 5-15 parts of Schisandra chinens P.E, 5-15 parts of Rhizoma Polygonati extract, manna oligosacchride
3-10 parts, 1-5 parts of B6.
It is preferred that a kind of Halth-care composition for improving sleep, is grouped as: Walnut extract 30 by the group of following parts by weight
Part, 30 parts of Semen Ginkgo extract, 10 parts of Radix Pseudostellariae extract, 10 parts of Schisandra chinens P.E, 10 parts of Rhizoma Polygonati extract, manna oligosacchride 8
Part, B62 parts.
