Description

Technical Field

[0001] The present invention relates to the technical field of health care and skin care, and in particular to a pharmaceutical composition for treating skin atrophy and the like caused by postpartum hormones and its application. Background Art

[0002] Cactus flower is the flower of perennial shrub cactus of Cactaceae. It is yellow and can be dried and used as medicine. It has the effects of clearing heat and moistening lungs, calming nerves and calming mind. It can treat tuberculosis, bronchitis, cervical lymphadenopathy, palpitation and other diseases. The main active ingredients of cactus flower are polysaccharides, flavonoids, sterols, alkaloids, etc., which have multiple biological activities and pharmacological effects such as anti-free radicals, antioxidants, antibacterial and antiviral, anti-inflammatory, and anti-cancer. It is known that external application of cactus can make the drug power directly reach the lesion to play a role, and can also make the drug properties enter the inside through the skin and fur, promote the regulation of meridians, and is often used to treat acute mastitis after childbirth. It is further discovered that cold compress of sliced ​​cactus on the breast can also reduce the skin temperature of breast swelling, keep it moist, and beautify the local skin of the breast. With the progress of the times and the improvement of living standards, cactus flower has become a popular health direction in the world as a dual-purpose product for medicine and food. After reviewing relevant literature, it was found that there are not many studies on cactus flowers at home and abroad, and there are even fewer in-depth studies on the physiological activities of cactus flowers. There is a lack of in-depth research on skin problems and molecular mechanisms caused by postpartum immune function and hormone levels.

[0003] Melibiose is a right-handed disaccharide, which is a disaccharide formed by the combination of D-galactose and D-glucose 1,6. Its chemical system name is O-α-galactopyranosyl-(1→6)-D-glucopyranose. It exists in floating wheat, honey, and legumes, but the content is relatively small. In industry, yeast is often used to ferment raffinose to produce melibiose. Melibiose has anti-inflammatory properties and can slow down the allergic reaction of the skin. It has good permeability on the skin, can improve skin condition, increase skin moisture, slow down the degradation of elastin, maintain skin elasticity, and improve eyelid swelling and eye bags. Conventional cell experiments show that melibiose exerts anti-inflammatory and anti-aging effects by promoting the production of type 3 collagen, inhibiting the activity of elastase, the activity of B-16 melanocytes, and the production of interleukin IL-8. Exploring the immune anti-aging mechanism of melibiose in postpartum skin has important scientific and application value.

[0004] Abalone peptide is a small molecule peptide (<1000Da) obtained by proteolysis technology using abalone as raw material. The Compendium of Materia Medica records that abalone is flat in nature, sweet and salty in taste, can improve eyesight, nourish deficiency, clear heat and nourish yin, nourish blood and benefit the stomach, and nourish the liver and kidneys, and is known as the "eye-improving fish". The Annotations to the Classic of Materia Medica records that abalone can improve eyesight, regulate menstruation and moisten the intestines, and is mainly used to treat diseases such as irregular menstruation and leukorrhea, which is related to the blood stasis disease recorded in the Classic of Internal Medicine. Abalone peptide contains rich peptides, amino acids, natural polyphenols, xanthines, ceramides and other ingredients, and has the effects of anti-oxidation, delaying aging, improving immunity, improving sleep quality, and relieving fatigue. With the improvement of people's living standards, abalone peptides, which are constantly developed under the medicinal value of abalone, have entered the research field of scientific researchers, confirming that the anti-aging, whitening and wrinkle-removing effects of abalone peptides on the skin are produced by removing free radicals in the body and preventing tyrosine in the skin from converting into melanin. In recent years, relevant literature reports at home and abroad have mainly focused on new technologies and industrialization of abalone peptide production and abalone peptide active substances. The actual mechanism and mode of action of the active substances need to be studied urgently.

[0005] Changes in female hormones have an important impact on women's lives. Female aging is caused by changes in hormone levels in women. Women gradually enter the aging period from the age of 35, which is mainly manifested in: menopausal syndrome, uterine atrophy, vulvar and vaginal atrophy, pelvic organ ptosis, breast atrophy, skin changes, etc. Among female hormones, estrogen and progesterone play a dominant role in the regulation of female aging, and estrogen and progesterone have become the research hotspots of female hormone anti-aging. Estrogen, also known as female hormones and female hormones, is a major type of female hormone. Estrogen is divided into two major categories, both of which are steroid hormones, namely estrogen (also known as estrogen) and progesterone. Changes in estrogen and progesterone levels are closely related to skin aging. Pregnant women have higher levels of estrogen and progesterone in their bodies during pregnancy. After delivery, the secretion of estrogen and progesterone gradually decreases, and the hormone level begins to decline, so the skin becomes loose, dry, and wrinkles appear. Therefore, it can be seen that the reduction of estrogen and progesterone does accelerate the aging process of the human body. Therefore, it is crucial to deeply study the mechanism of action of estrogen and progesterone on female aging.

[0006] The skin is composed of three layers, epidermis, dermis and subcutaneous layer. The dermis is mainly composed of extracellular matrix (ECM), such as collagen. In addition, the dermis also contains structures such as blood vessels, lymphatic vessels, nerves, sweat glands and sebaceous glands. Within the dermis, there are diverse populations of mononuclear phagocytes, including dermal dendritic cells and dermal macrophages. Dendritic cells are sentinels of the immune system that sample the microenvironment and either present antigens to resident T cells or migrate to lymph nodes through lymphatic vessels to initiate an immune response.

[0007] Calreticulin (CRT) is an endoplasmic reticulum (ER) Ca2+ Binding protein, molecular chaperone, widely distributed, also exists in the cell nucleus, nuclear membrane, cell membrane surface and extracellular matrix. CRT has different functions in different locations. CRT in ER has the function of regulating intracellular Ca 2+ Homeostasis, assisting protein correct folding, regulating cell apoptosis, etc. Non-endoplasmic reticulum CRT regulates cell adhesion, migration, proliferation and fibrosis, mediates the recognition and phagocytosis of apoptotic cells, and also participates in antigen presentation in the adaptive immune response and tumor cell recognition process. It has good clinical application prospects in wound repair, tumor and autoimmune disease treatment. Studies have found that CRT can appear on the surface of almost all immune cells, such as monocytes, macrophages, neutrophils, T cells, DCs, fibroblasts and endothelial cells, and the expression of CRT changes with age, suggesting that CRT plays an important immunological function in the extracellular environment and aging immunity. Although great progress has been made in the study of the immunobiological function of CRT in recent years, there are still many unresolved issues, such as how does CRT on the surface of immune cells play an immune response function? How does CRT affect the activation process of immune cells? What is the mechanism by which CRT affects immunity? I believe that with the continuous deepening of research, our understanding of the immunoregulatory effect of CRT and the body's immune regulatory network will be clearer.

[0008] NF-κB is a family of transcription factors. After cells are stimulated by inflammatory mediators, viral infection, oxidative stress, etc., NF-κB can be activated, thereby initiating the transcription of related genes and participating in various biological processes, including immune response, inflammation, cell growth, survival and development. According to the different activation pathways, NF-κB signals can be divided into classical activation pathways and atypical activation pathways. The latter helps to express pleiotropic biological functions by controlling the fine-tuning of its own and / or common NF-κB target genes, which are mainly related to the development and function of immune cells, namely T cells, B cells, thymocytes, macrophages, fibroblasts, and neurons.

[0009] The skin is the interface between the body's internal environment and the outside world, and the immune system plays an important role in this interface. Lymphocyte homing (LH), that is, lymphocytes selectively cross the capillary high endothelial venules, migrate in a directional manner and enter peripheral organs or specific tissue areas, is an important process in the body's immune system, especially the homing of T lymphocytes, which is crucial for immune surveillance. Peripheral mature T lymphocytes are divided into CD4 + and CD8 +T lymphocytes, but the initial T cells (TN) after antigen activation can be divided into central memory T cells (TCM), effector memory T cells (TEM), and effector T cells (TEFF). The three types of T lymphocytes each express different constitutive receptors and ligands, allowing them to interact with microvessels or epithelial cells in different regional tissues, and then migrate to specific sites to play a role. TN can preferentially migrate to secondary lymphoid tissues. TCM can preferentially migrate to secondary lymphoid tissues and bone marrow, while TEM and TEFF migrate to peripheral non-lymphoid tissues such as skin, intestinal mucosal lamina propria, liver, lungs and inflammatory sites to play an effector role in killing target cells. Different T lymphocyte subsets migrate to different lymphoid and non-lymphoid tissues, allowing the body to perfectly exert its immune defense, immune surveillance and immune self-stabilization capabilities.

[0010] The average length of telomeres shortens with the increase of cell division times and age. The proliferation capacity of normal human fibroblasts in vitro culture is not unlimited. Cell division and proliferation will appear aging after 40 to 60 generations. This is because DNA polymerase cannot completely replicate the 3' end of linear chromosomes, resulting in the continuous loss of telomeric DNA repeat sequences with each round of DNA replication. When it shortens to a certain length, the cell enters the aging stage. A large number of studies have shown that telomeres play an important role in individual aging. Telomere length is one of the key factors of aging. The shortened telomere length in aging T cells may be one of the reasons why aging leads to abnormal immune function of the body.

[0011] Because the skin is exposed, it is easily affected by external environmental factors (ultraviolet radiation, air pollution, smoking, etc.), and with the increase of age, the human immune system undergoes characteristic changes, which often lead to weakened immune ability and cause immune aging. When aging causes the immune system to decline in function, it can lead to a decrease in the body's ability to clear harmful substances such as toxins and pathogens, presenting a chronic inflammatory state. In addition, changes in various characteristic cells of the skin's immune system also affect the skin, the largest immune organ, causing the epidermis and dermis to become thinner, water loss to increase, and collagen and elastin to break, which seriously damages the skin's immune defense ability. Under the combined effect of many factors, skin aging occurs.

[0012] Aging is the final outcome that is difficult for individuals of any species to avoid. With the development of society, people's pursuit of anti-aging has intensified, but our research on anti-aging mechanisms is still quite limited. Given its importance, the development of anti-aging compositions with novel mechanisms, outstanding activity, significant efficacy, and high safety is one of the hot topics in biological research. Summary of the invention

[0013] The purpose of the present invention is to solve the above problems and provide a pharmaceutical composition with anti-aging activity and its application.

[0014] In order to achieve the above-mentioned object, the technical scheme of the present invention is as follows: a composition for treating skin deterioration, characterized in that the composition consists of cactus flower extract, melibiose and abalone peptide.

[0015] Furthermore, the composition is composed of 0.01% to 16% of cactus flower extract, 0.05% to 12% of melibiose, and 0.01% to 15% of abalone peptide in terms of mass fractions.

[0016] Furthermore, the composition exhibits anti-aging activity by activating calreticulin in fibroblasts in postpartum skin, enhancing the antigen presentation ability of dendritic cells, activating the "non-classical" NF-κB signaling pathway, promoting lymphocyte homing, and extending T cell telomeres.

[0017] Furthermore, the composition is combined with auxiliary materials or solvents to prepare skin care and anti-aging products such as facial masks, eye creams, essence water, essence milk, facial creams, body lotions, oral liquids, capsules, etc.

[0018] The present invention also provides an anti-aging skin care product containing cactus flower extract, melibiose and abalone peptide. The product contains 0.01% to 16% of cactus flower extract, 0.05% to 12% of melibiose, and 0.01% to 15% of abalone peptide in terms of mass fraction, and can treat skin deterioration problems caused by postpartum hormonal changes.

[0019] Furthermore, the cactus flower extract is a water extract of cactus flower, which is obtained by freezing and crushing fresh cactus flowers in a low-temperature refrigerator, stirring them evenly under 60-65°C water, adding activated carbon and letting them stand for 24 hours, and removing the activated carbon by centrifugation at 4000r / min for 5 minutes.

[0020] Furthermore, the product activates fibroblast calreticulin in the skin, enhances the antigen presentation ability of dendritic cells, activates the "non-classical" NF-κB signaling pathway, promotes lymphocyte homing, and prolongs T cell telomeres, thereby exerting an anti-aging effect.

[0021] Furthermore, the product includes the following forms: facial mask, eye cream, essence water, essence lotion, facial cream, body lotion, oral liquid or capsule.

[0022] The present invention also provides a method for preparing an anti-aging skin care product containing cactus flower extract, melibiose and abalone peptide, comprising the following steps:

[0023] Step 1, after freezing and crushing fresh cactus flowers in a low-temperature refrigerator, stir them evenly in water at 60-65° C., add activated carbon and let them stand for 24 hours, then centrifuge at a speed of 4000 r / min for 5 minutes to remove the activated carbon, and obtain a light yellow cactus flower water extract;

[0024] Step 2: Mix the above-mentioned cactus flower water extract, melibiose and abalone peptide according to a predetermined mass ratio, stir evenly, add appropriate amount of auxiliary materials or solvents to prepare an anti-aging skin care product.

[0025] Furthermore, in step one, through the method of low-temperature freezing and appropriate temperature heating extraction, the structural changes of the natural active ingredients of cactus flowers are minimized, their natural aroma is retained, and the extraction efficiency is effectively improved.

[0026] Compared with the prior art, this solution has the following beneficial effects:

[0027] The composition of the invention has anti-aging function and is suitable for anti-aging of postpartum skin.

[0028] The melibiose and abalone peptide in the composition of the present invention have certain immune-enhancing activity, but it is weak, and the activity of the combination of the two is significantly higher than that of any single component, which is innovative. Mechanism research found a new mechanism of the composition, that is, melibiose and abalone peptide activate calreticulin in fibroblasts in postpartum skin, enhance the antigen presentation ability of dendritic cells, and activate the "non-classical" NF-κB signaling pathway, promote lymphocyte homing, and extend T cell telomeres, showing anti-aging activity, which is innovative. The anti-aging mechanism of melibiose and abalone peptide is different from the new mechanism produced by the composition of the present invention. Previous studies have found that melibiose has anti-aging activity by promoting the production of type 3 collagen and inhibiting the activity of elastase. Abalone peptides exert anti-aging effects by scavenging free radicals in the body through their own natural polyphenols and xanthines, and no new mechanism of the composition of the present invention has been found.

[0100] 2.8 Skin efficacy test methods

[0101] 2.8.1 Skin patch allergy test

[0102] Test method According to the relevant requirements of "Human Skin Patch Test" in the 2015 edition of "Technical Specification for Safety of Cosmetics", 40 female volunteers two weeks postpartum were selected to test the anti-aging compositions prepared in Examples 1 to 3 of the present invention, and the volunteers were observed at 1h, 12h, and 24h for adverse skin reactions such as redness, swelling, and itching.

[0103] 2.8.2 Determination of moisture content of stratum corneum (CPA)

[0104] The moisture content of the stratum corneum represents the degree of skin dryness. Comparing the moisture content of the stratum corneum before and after use can reflect the moisturizing effect of the product. If the skin is very dry, the CPA value will be lower. If the skin returns to normal dryness, the higher the moisture content, the higher the CPA value.

[0105] Test method: 40 postpartum female volunteers with healthy skin and stratum corneum moisture content <30 were selected, one person was selected from each age group, and 10 people were selected in a group, for a total of 4 groups. During the experiment, the subjects applied the same amount of anti-aging composition to the skin behind the ears every morning and evening, and no other cosmetics were applied. The changes in skin hydration rate (MMV) before using cosmetics and on the 14th and 28th days were tested using Corneometer, and repeated 5 times to obtain the average value.

[0106] 2.8.3 Skin melanin determination

[0107] The determination of melanin content is the most powerful method for testing whitening and anti-freckle products. The difference in human skin color mainly depends on the content and distribution of melanin. Melanin is mainly formed in melanocytes in the basal layer of the epidermis of human skin. Under the action of enzymes such as tyrosinase, tyrosine in melanocyte tissue is gradually converted into true melanin through intermediates such as dopa, dopaquinone, dopachrome, and dihydroxyindole. The lower the melanin content, the better the whitening and anti-freckle effect.

[0108] Test method: 40 postpartum female volunteers with healthy skin and stratum corneum moisture content <30 were selected, with 10 people in each group, for a total of 4 groups. During the experiment, the subjects applied the same amount of anti-aging composition to the skin behind the ears every morning and evening, and no other cosmetics were applied. The MEXAMETERMX18 skin pigmentation meter was used to test the skin melanin content before using cosmetics and on the 14th and 28th days, and the average value was obtained by repeating 5 times.

[0109] 2.8.4 Skin elasticity measurement

[0110] The commonly used method for elasticity measurement experiments is the suction method designed based on the principles of suction and stretching. The elastic parameters of the skin are obtained through the relationship curve between skin stretching length and time. This method is simple and rapid, and the measurement is not affected by skin thickness. It is a good indicator for studying skin aging.

[0111] Test method: 40 postpartum female volunteers with healthy skin and stratum corneum moisture content <30 were selected, with 10 people in each group, for a total of 4 groups. During the experiment, the subjects applied the same amount of anti-aging composition to the skin on the inside of their arms every morning and evening, and no other cosmetics were applied. According to the group standard T / ZHCA 005-2019 "Test method for the effect of cosmetics on skin elasticity", the skin elasticity characterization values ​​were measured before trial and 14 days and 28 days after trial. The results are expressed as the elasticity parameter R2, without units.

[0112] 2.8.5 Determination of skin wrinkle area ratio

[0113] The wrinkle area ratio indicates the size of the wrinkle area. The smaller the wrinkle area ratio, the fewer wrinkles there are. The larger the difference in this indicator, the better the improvement effect of wrinkle reduction.

[0114] Test method: 40 postpartum female volunteers with healthy skin and stratum corneum moisture content <30 were selected, with 10 people in each group, for a total of 4 groups. During the experiment, the subjects applied the same amount of anti-aging composition to their facial skin every morning and evening, and were not allowed to apply any other cosmetics. The skin wrinkle area was measured before the trial and 14 days and 28 days after the trial using a skin wrinkle meter.

[0115] 2.9 Statistical analysis methods

[0116] The data of each group were expressed as (X±SD). One-way analysis of variance (ANOVA) was used to compare the differences between the experimental groups and the model group. The LSD-t test was used for pairwise comparison. P<0.05 indicated that the difference was statistically significant.

[0126] The results of immunocytochemical staining of CRT expression in fibroblasts showed that the CRT expression signal strength in fibroblasts of different experimental groups and model groups was stronger than that in fibroblasts of the model group. Figure 3 The results of ELISA detection of CRT expression showed that the CRT expression value of the control group was 2.21±0.17 (A), the model group was 1.14±0.07 (A), and the CRT expression values ​​of different experimental groups were 1.85±0.10 (A), 1.55±0.09 (A), 1.67±0.11 (A), 1.82±0.15 (A), and 2.14±0.13 (A), respectively, all showing different abilities to promote CRT expression, and the differences in CRT expression values ​​between the combination group and each group had different significance.

[0129] Depend on Figure 4 It can be seen that in the experiment, each group of DCs can stimulate the proliferation of T cells to varying degrees in the presence of antigen (OVA), and each experimental group has a good ability to promote the proliferation of sensitized lymphocytes. The combination experimental group can significantly enhance the antigen presentation ability of DCs (P < 0.0001), indicating that DCs stimulated by the combination group have a good antigen presentation function. It suggests that the composition of the present invention can enhance the antigen presentation ability of dendritic cells.

[0131] Figure 5 The results showed that the expression of p52, a specific protein of the NF-κB signaling pathway, was enhanced to varying degrees in the experimental groups of fibroblasts under different treatments, and the p52 protein content in the nucleus of the experimental group of the combination was significantly higher than that of the model group, indicating that the experimental group significantly promoted the nuclear translocation of NF-κB (P < 0.0001). In subsequent experiments, we added the NF-κB inducing kinase (NIK) inhibitor B022 for reverse verification, and the results showed that after the addition of B022, the NF-κB activation process was significantly inhibited. In summary, the composition of the present invention can promote the nuclear translocation of p52 in cells by activating NF-κB.
