[0053] Example 9: Anti-allergic evaluation test of encapsulated peony stamen microcapsules (PSBL)
[0054] Allergy is an abnormal reaction of the body, which is an abnormal reaction to allergens. Allergies will occur only when allergens come into contact with people with allergic constitutions. Allergens include hundreds of chemicals, ultraviolet rays, pollen, dust, foreign proteins, etc. In the process of allergic reactions, allergic mediators play a direct role. Allergens are the external cause of allergic symptoms, while low immunity and the oxidative damage of mast cells and basophils by a large number of free radicals are the internal causes of allergic symptoms. There are two types of cells in the human body, namely mast cells and basophils, which are widely distributed in the nasal mucosa, bronchial mucosa, gastrointestinal mucosa, and around the microvessels in the connective tissue under the skin and in the capsule of the internal organs. These two types of cells contain allergic mediators such as histamine, leukotrienes, 5-hydroxytryptamine, and kinase. Mast cell lines (RBL-2H3 cells) were used to evaluate the anti-allergic efficacy of coated peony stamen microcapsules (PSBL). When mast cells are stimulated by IgE antibodies or calcium ion carriers, they can release a large amount of β-glucuronidase (β-hexosaminidase) through degranulation. The amount released can be used to determine whether the peony extract (PSE) to be tested has the potential to inhibit allergic reactions. 4 cells / well) were cultured in a 96-well plate and treated with coated peony stamen microcapsules (PSBL) for 24 hours, followed by the addition of anti-DNP IgE Ab (1 μg / mL) and incubation for 6-12 hours to sensitize mast cells. After washing the supernatant, DNP-BSA (100 ng / mL) was added and incubated for 1 hour to activate mast cells. The supernatant was collected and frozen for storage. An equal volume of supernatant and p-NAG substrate (1 μM) were added to the 96-well plate and the absorbance at 405 nm was measured after incubation at 37°C for 1 hour (BioTek, Synergy TM 2, USA). The experimental results showed that the release rate of β-hexosaminidase was 62.3% when calcimycin A23187 (1 µM) was used to induce allergic reactions. After PSBL was applied to mast cells, the activity of β-hexosaminidase was 49.6%, indicating that PSBL could inhibit the activity of β-hexosaminidase and had anti-allergic effect.

[0057] Example 10: Experiment on promoting cell energy production by encapsulated peony stamen microcapsules (PSBL)
[0058] Determination of intracellular adenosine triphosphate (ATP) content. ATP is the most abundant energy carrier molecule in the body. It can use the chemical energy in food molecules and release it to provide fuel for work in cells. To evaluate whether the encapsulated peony stamen microcapsules (PSBL) can induce the generation of cellular energy ATP, the ApoSENSORTM Cellviability assay kit was used to quantify the amount of ATP induced. Human skin keratinocytes (1.5×10 5 cell / mL) in a 96-well plate and grown in a 37˚C, 5% CO2 incubator for more than 24 hours. Then, PSBL was added and reacted for 24 hours. The supernatant was removed and washed with PBS. 100 μL Nuclear releasing reagent was added and reacted for 5 minutes. Then, 10 μL ATP monitoring enzyme was added and the ATP content was measured by cold light instrument (BioTek, Synergy TM 2, USA). Test results: The ATP content of untreated human skin keratinocytes was 100% in the control group. After being treated with PSBL, the ATP content in the cells increased to 108.7%. The test results showed that the cells were stimulated by PSBL and the ATP content in the cells increased by 8.7%, indicating that PSBL has the effect of promoting the production of cellular energy ATP.

[0062] Mutations in the lamin A gene can damage DNA repair function, making the genome unstable and leading to premature aging. The anti-aging mechanism found that Lamin A protein can stimulate the longevity gene SIRT1, allowing cells to self-protect, self-renew and delay aging. To evaluate the effect of coated peony stamen microcapsules (PSBL) on regulating the expression of anti-aging protein Lamin A, thereby delaying cell aging. Human skin keratinocytes (HaCaT cells) (1.5×10 5cell / mL) was cultured in a 10 cm diameter dish and cultured in a 37°C and 5% CO2 incubator for at least 24 hours. The coated peony stamen microcapsules (PSBL) were added and placed in the incubator for 24 hours. When the reaction time was reached, protein extraction was performed using RIPA buffer, and then SDS-PAGE electrophoresis was performed until the target protein was separated. After adding 0.5% skim milk for 2 minutes, the first-level antibody was added for reaction for 10 minutes, and then rinsed 3 times with 0.1% phosphate-buffered saline (PBST), and then the second-level antibody was added for reaction for 10 minutes, and then rinsed 3 times with 0.1% PBST. Finally, the ECL cold light sensing reagent was added, the cold light camera system was placed to take pictures, and image J was used to quantitatively analyze the protein expression. The experimental results are shown in the following table. Figure 4 As shown: After human skin keratinocytes (HaCaT cells) were treated with PSBL, the expression of Lamin A protein in the cells was analyzed. The cytoskeletal protein β-actin was used as a quantitative control group. The results showed that compared with the control group (Lamin A expression was 1.0), the expression of Lamin A increased to 3.8 after PSBL treatment, indicating that PSBL can activate Lamin A protein, which is speculated to have anti-aging effects.
[0063] Example 12: Encapsulated Peony Stamen Microcapsules (PSBL) regulate the expression of Tyrosinase, a gene that inhibits pigmentation; regulates the expression of mTOR, a gene that inhibits aging; and regulates the expression of TOP1, a gene that promotes telomerase
[0064] The experiment was conducted by real-time quantitative qPCR. The expression of the tyrosinase gene in the mechanism of melanin production regulated by PSBL was analyzed; the expression of the gene that inhibits aging (mTOR) was regulated; and the expression of the gene that promotes telomerase (TOP1) was regulated. Tyrosinase is an oxidase and the rate-limiting enzyme that regulates melanin production. This enzyme participates in melanin synthesis. By regulating and inhibiting the activation of Tyrosinase, melanin production and pigmentation can be inhibited. mTOR is a serine-threonine protein kinase, which is an important factor causing aging and canceration. It promotes cells to absorb heat, shuts down the autophagy mechanism, and prevents cell renewal. Therefore, in recent years, studies on the inhibition of mTOR expression have pointed out that by inhibiting the expression of mTOR in aging cells, cells can have the potential for regeneration. The function of telomeres is to maintain the integrity of eukaryotic chromosomes and control the cell division cycle. After cell division, telomeres will stably replicate the post-division DNA to ensure the integrity of the genetic sequence. However, each time a cell divides, the telomeres will shorten. When the telomeres are exhausted, the cell will start apoptosis. Therefore, telomeres are considered the best marker of aging. Telomerase can replenish telomeres, extend the number of cell divisions, and slow down the aging process. TOP1 is a telomere protection protein. Promoting its expression can enhance the protection of telomeres. Melanoma cell lines (B16 cells) and human skin keratinocytes (HaCaT cells) (1.5×10 5 cell / mL) was 1×10 5The cells were inoculated at a density of 100 cells / mL in a 6-well plate and cultured for 24 hours. RNA of melanoma cell lines was extracted after PSBL was mixed with serum-free culture medium for 72 hours; RNA of human skin keratinocytes was extracted after PSBL was mixed with serum-free culture medium for 24 hours. The supernatant was collected into a 15 mL centrifuge tube, cells were removed with Trypsin, and cells were collected with PBS and centrifuged to remove the supernatant. 1 mL REzolTMC&T was added and mixed evenly for 5 minutes at room temperature to dissolve the cells. 200 μL chloroform was added and mixed evenly for 15 seconds. Total RNA was purified and isolated by reacting at 4°C for 5 minutes. Centrifugation was performed at 12,000 rpm at 4°C for 10 minutes. The top transparent layer in the centrifuge tube was taken into a 1.5 mL microcentrifuge tube soaked in DEPC-H2O and sterilized. Add an equal volume of isopropanol and mix well. Let stand at 4°C for 5 minutes to precipitate RNA. Centrifuge at 12,000 rpm at 4°C for 10 minutes. Remove the supernatant. Add 200 μL of 75% ice alcohol to wash RNA. Centrifuge at 12,000 rpm at 4°C for 10 minutes. Completely remove the supernatant and invert in the air to dry in a sterile operating table to completely evaporate the moisture in the centrifuge tube. Add 100 μL of 0.1% DEPC-H2O to disperse RNA and store in a -80°C refrigerator. Quantify RNA: Take 2 μL of RNA in 198 μL of 0.1% DEPC-H2O, mix well, take 100 μL in a micro quartz tube, and measure the absorbance at OD260 nm and OD280 nm using a spectrophotometer (BioTek, Synergy TM2, USA). Reverse transcription (RT): 0.1% DEPC-H2O was added to adjust the concentration to 2 mg RNA, and the volume was made up to 12.5 μL. After adding 1 μL OligodT primer and mixing evenly, 70 μL was added for 2 minutes, and then quickly placed on ice. Then 4 μL 5× MMLV-RT buffer solution, 1 μL 10mM Each dNTP, 0.5 μL RNase inhibitor and 1 μL MMLV RTase were added, and the reaction was incubated at 42°C for 1 hour, and then at 94°C for 5 minutes. Then, ice-cold ddH2O was added to make the volume up to 100 μL, and the cDNA preparation was completed and stored in a -80°C refrigerator. The first step of qRT-PCR was completed using a fluorescence detection system (prism 7700 sequencing detection system) and Qiagen's Quantitect SYBR Green RT-PCR kit according to the manufacturer's procedures. The primer sequences were the same as those used to generate arrayed cDNAs. The amplification conditions were as follows: reverse transcription at 50°C for 30 minutes, followed by PCR activation at 95°C for 15 minutes. Melting temperature was 95°C for 15 seconds, and annealing / extension was performed at 60°C for 1 minute, for a total of 40 cycles. The size of the amplified product was confirmed by the cycle threshold (CT) (ΔΔCT) method, and the CT values of the control group and the laboratory were compared. The β-actin gene was used for quantitative analysis. The fold change of gene expression was calculated. Take 10 μL cDNA into a microcentrifuge tube, add 5 μL 10× reaction buffer, 2 μL 25 mM MgCl2, 0.8 μL 10 mM dNTP and 1 μL each of 50 μM upstream and downstream primer, Taq DNA polymerase (5 unit / μL), and finally add deionized water to make the total volume reach 50 μL, and place it in an automatic temperature cycler (MyGo Pro real-time PCR) for PCR reaction. The test results are as follows Figure 5 As shown: Genetic analysis experiments have shown that the coated peony stamen microcapsules (PSBL) regulate and inhibit the expression of the pigmentation mechanism gene Tyrosinase in melanoma cells; regulate and inhibit the expression of the aging gene mTOR in human skin keratinocytes, and regulate the expression of the telomerase-promoting gene TOP1.
