Background technology
The bioprocess of the complexity that the ovary aging is a multifactor interaction, build up.Constantly consume along with day in year passing follicle, it is the main cause of ovary aging that Follicle number descends; And body intracellular metabolite product piles up that microenvironment changes in the ovary, such as the damage to follicle of free radical, advanced glycation end products, and the continuous accumulation of the factors such as Mitochondrial DNA Mutation, telomere shortening, the quality of residue follicle also reduces simultaneously; The expression of series of genes and changing function in the ovary, and the function of the secretion precision control ovary of H-P-O axle (Hypothalamus-Pituitary-Ovary Axis, hypothalamic-pituitary-ovarian axis) hormone.The ovarian function decline is that ovary is old and feeble, and take menopause as performance, in the past menopause in 40 years old is called premature ovarian failure (Premature Ovarian Failure, POF), and namely the pathologic ovary is old and feeble.The ovarian function decline can cause ovarian dysfunction disease (such as polycystic ovarian syndrome, dysfunctional uterine bleeding etc.), then depletion causes perimenopausal syndrome, each tract senile disease appears in these diseases in succession: coronary heart disease, cerebrovascular incidence rate obviously improve in the blood circulation, easily send out presenile dementia, depression among the central nervous system, osteoporosis is occurred frequently etc. because calcium loss sharply increases.In recent years, along with rhythm of life accelerate and learning pressure excessive, occur in the existing obviously trend of increase of ovary decline disease association disease among the women.Because there are youth, middle age or elderly woman in each family, so the old and feeble above-mentioned disease that produces of ovary become the social problem that generally is concerned about, the research of this disease become focus and the difficult point of domestic and international reproductive development circle.
At present both at home and abroad research thinks that ovary aging and heredity, immunity, metabolism, viral infection and the factor such as iatrogenic are relevant more.Be summarised as the following aspects: 1 karyotype is unusual, by the organon phase to the old and feeble patient of chromosomal abnormality ovary, some syndrome genes mainly concentrate on X chromosome and the autosome, what are relevant with Inheritance for karyotype unusual, and the gene mutation that causes of environmental factors also is the key factor that causes this disease in addition.2 immunity factors, may with cytokine induction granular cell and lutein cell, mainly be histocompatibility complex (MHC) class antigen presentation, bring out the autoimmune response of body, it is relevant that granular cell and follicle are damaged.In addition, think that in addition ovarian function fails and the generation of ovary autoantibody and the autoimmune disease that merges other endocrine bodies of gland or system, relevant such as autoimmune thyroiditis, systemic lupus erythematosus (sle), myasthenia gravis, parathyroid function decline, rheumatoid arthritis, idiopathic thrombocytopenic purpura, diabetes etc.3 promoting sexual gland hormone and receptor abnormality thereof, the conduction defect of promoting sexual gland hormone FSH, LH and receptor thereof (FSHR, LHR) can cause the ovarian function decline.4 azymias can cause galactosemia, and galactosemia occurs relevant with the ovarian function decline.Galactose can directly damage oocyte, and its metabolite can produce infringement to ovary essence again, and the infiltration of galactose molecule also can change the activity of promoting sexual gland hormone, thereby causes the exhaustion of folliculus ovarii.5 ovary destructive factors, day by day frequent along with women's social activity, being not intended to the Long Term Contact reflected ray stimulates, or accepts lonizing radiation heavy dose of or over a long time because of work, disease, contingency, all can destroy ovary.6 other dangerous factors, smoking, depression, the exogenous E of long-term a large amount of contacts
2With nullipara and ovary decline close relationship is arranged.And heavy metal class environmental hormone is still blank on the impact research of ovarian function decline, and along with China's rapid development of economy, this class environmental factors will be grown health to the Chinese people people's livelihood can produce long-range adverse effect.
Hormone replacement therapy (Hormone replacement therapy, HRT) be the important method of the present old and feeble related symptoms of modern medicine treatment ovary and disease, but existing research shows that obviously it has multiple side effect and carcinogenecity at a specified future date, is subject to significant restrictions its clinical practice.Corresponding this state, follow Traditional Chinese medical theory in China, advocate " the kidney invigorating tonifying YIN, soothing the liver nourishing blood " and delay the ovary aging, the treatment of employing Chinese medicinal formulae, but also do not getting clear in the situation of its cause of disease, pathology at present, exist the mistaken ideas of abusing medicine, disorderly treating, and it is unclear that the compound medicine treatment has the effective substance basis, the defective that mechanism of action is not clear can't make Chinese medicine move towards modernization, moves towards internationalization.
Oxidized resveratrol (Oxyresveratrol), have another name called 4-[(E)-2-(3, the 5-dihydroxy phenyl) vinyl] benzene-1, the 3-glycol, belong to the trans stilbene compounds, in various plants, found at present its existence, belong to (Artocarpus) such as the Fructus Artocarpi Heterophylli in the Moraceae (Moraceae), Morus (Moraceae), orange Morus (Maclura), the smilax (Smilax) of Liliaceae (Liliaceae), the Gnetum (Gnetum) of Veratrum (Veraturm) and Gnetaceae (Gnetaceae) etc.Oxidized resveratrol is yellow solid, molecular formula: C
