Description

Technical Field

[0001] The invention belongs to the technical field of eye health, and in particular relates to a product with eye protection purpose. Background Art

[0002] The "14th Five-Year Plan for National Eye Health" issued by the National Health Commission proposes to continue to promote the high-quality development of my country's eye health and further improve the eye health level of the people. Eye health is an important part of national health, involving people of all ages throughout their life. However, as electronic products gradually penetrate into people's lives, excessive use of eyes has become the norm, troubling people from children to the elderly. Myopia problems in children and adolescents, high blue light exposure problems in young and middle-aged people, and macular degeneration problems in the elderly are all related to varying degrees of retinal light damage. In particular, age-related macular degeneration (AMD) is a difficult-to-treat disease that seriously damages vision and is one of the leading causes of blindness in adults over 50 years old worldwide. With the aging of the population, the incidence of AMD is also increasing year by year. It is estimated that the number of AMD patients worldwide will reach 288 million by 2040, and there is currently no drug treatment with obvious efficacy except for anti-VEGF drugs in clinical practice. It can be seen that related retinal diseases and even visual impairment caused by retinal light damage have a very serious impact on the physical and mental health and quality of life of the people, and increase the burden on families and society. Therefore, preventing retinal light damage and promoting visual health have become important issues that need to be urgently addressed in the Healthy China strategy. Summary of the invention

[0058]

[0059] 1.4 Evaluation of blue light eye protection efficacy

[0060] Wild-type AB strain zebrafish at 1 dpf were randomly selected after hatching and irradiated with blue light to establish a zebrafish blue light eye injury model. At 3 dpf, model zebrafish with good developmental status were randomly selected and allocated into 6-well plates, with 30 zebrafish in each well (experimental group). Different concentrations of Aronia melanocarpa fruit extract were dissolved in water and administered (the concentrations are shown in Table 2), and the positive control lutein was at a concentration of 62.5 μg / mL. At the same time, a normal control group and a model group were set up, and the volume of each well was 3 mL. After treatment at 28 °C for 1 day, the zebrafish in each experimental group were stained with AO in the dark for 30 min. After washing 3 times with standard dilution water, 10 zebrafish were randomly selected from each experimental group and placed under a fluorescence microscope for photographing. The Image J software was used to analyze and collect data, and the fluorescence intensity of apoptotic cells in the zebrafish eyes was analyzed and statistically counted. The blue light eye protection efficacy of Aronia melanocarpa fruit extract was evaluated based on the statistical analysis results of the above indicators. The statistical processing results were expressed as mean ± SE.

[0061] The results are shown in Table 2 and Figures 1-2 as follows. The zebrafish blue light eye injury model showed apoptosis of ocular cells. After treatment with different concentrations of Aronia melanocarpa fruit extract, the apoptosis of ocular cells in zebrafish could be significantly reduced, indicating that Aronia melanocarpa fruit extract has the eye protection effect against blue light-induced eye injury.

[0066] In this example, Prism 8 software was used for statistical chart drawing and statistical analysis. All data were expressed as mean ± standard error. The differences between two groups were analyzed by independent sample t-tests: ****P < 0.0001; ***P < 0.001; **P < 0.01; *P < 0.05; #P < 0.05; ##P < 0.01; P < 0.001; #P < 0.0001. * indicates the statistical difference between the model group and the normal control group, and # indicates the statistical difference between different administration groups and the model group

[0067] 2.1 Experimental animals

[0068] 8-week-old male BALB / c mice were purchased from Zhejiang Vital River Laboratory Animal Technology Co., Ltd. Before the experiment started, all mice were adaptively fed with 12:12 h light / dark in an animal room at a certain temperature and humidity for 1 week, and provided with normal food and drinking water every day. All experimental operations followed the guidelines for animal care and use of the Animal Research Institute of Zhejiang University

[0069] 2.2 Construction of mouse retinal light damage model

[0070] A self-made light box with a length of 108 cm, a width of 50 cm, and a height of 72 cm was used. The light intensity was detected by a light intensity meter to be 8500 - 10000 Lux. After eye examination of the mice, mice with normal eyes were randomly divided into a control group (12 mice), a model group (10 mice), a lutein group (100 mg / kg, 10 mice), a low-dose group of Aronia melanocarpa fruit extract (100 mg / kg, 10 mice), and a high-dose group of Aronia melanocarpa fruit extract (200 mg / kg, 10 mice). Lutein and Aronia melanocarpa fruit extract were suspended in a 5% sodium carboxymethylcellulose (CMC-Na) solution and administered by gavage once a day. Mice in the blank and model groups were gavaged with an equal volume of 5% CMC-Na. The administration was continued for 10 days. After 10 days, the mice in the model group, lutein group, low-dose and high-dose groups of Aronia melanocarpa fruit extract were dark-treated for 36 h, then atropine ophthalmic gel was applied to both eyes of the mice to dilate the pupils, and the mice were placed in a self-made lighting device with a light intensity of 8000 - 10000 Lux (the blank group was raised in a normal environment) for 24 h of continuous light exposure. After the light exposure ended, blood was collected by enucleating the eyeballs of each group of mice, and the eyeball tissues were collected for relevant detections in subsequent experiments.

[0071] 2.3 Main experimental instruments

[0072] The main instruments used in the experiment included a dehydrator, an embedding machine, a pathological slicer, a tissue spreading machine, an oven, glass slides, an upright optical microscope, an imaging system, a light intensity meter, an LED lamp, an electronic balance, an ultra-low temperature refrigerator, a pure water instrument, a shaker, an enzyme label instrument, etc.

[0073] 2.4 Experimental consumables and reagents

[0074] The consumables and reagents required for the experiment included atropine ophthalmic gel, FAS eyeball fixative, PBS buffer, malondialdehyde (MDA) content detection kit, Mouse IL-6 ELISA kit, xylene, differentiating solution, bluing solution, neutral gum, absolute ethanol, environment-friendly dewaxing solution, proteinase K, DAPI dye, anti-fluorescence quenching mounting medium, hematoxylin-eosin (H&E) high-definition constant staining kit, TUNEL kit, etc.

[0075] 2.5 Histopathological detection

[0076] For each group, 5 - 6 mouse eyeball tissues were subjected to H&E staining and apoptotic cell TUNEL fluorescence staining, and the histopathological changes of the mouse eyeball tissues were observed using an optical microscope (completed by Wuhan Sevier Biotechnology Co., Ltd.).

[0077] The retina is the most crucial part of the eye. The inner nuclear layer and the outer nuclear layer of the retina are the main structures of the retina. The outer nuclear layer of the retina is mainly composed of photoreceptor cells, which can receive light stimuli and convert light signals into electrical signals. The inner nuclear layer of the retina contains different types of neuronal cells, which can convert electrical signals into nerve impulses. It can be seen that the cells in the inner / outer nuclear layer of the retina play an important role in the reception and conduction of visual signals. The results of retinal H&E staining are as Figure 3 shown. Light damage caused morphological changes such as loosening and reduced thickness in the outer nuclear layer and the inner nuclear layer of the retinas of mice in the model group, indicating that light caused damage to retinal cells ( Figure 3 in A). Under light conditions, both low-dose and high-dose aronia fruit extracts could well improve the morphological changes in the outer nuclear layer of the retina and increase the thickness of the outer nuclear layer and the inner nuclear layer ( Figure 3 in B-C, Table 3). Moreover, the protective effect of aronia fruit extract on the outer nuclear layer and the inner nuclear layer of the retina was comparable to that of the positive drug lutein, indicating that aronia fruit extract has a good effect on improving retinal light damage.

[0078] The results of TUNEL fluorescence staining of apoptotic cells in retinal tissues are as Figure 4 shown. Light induced a large number of apoptotic retinal cells in mice in the model group (red fluorescence, Figure 4 in A). The high dose of aronia fruit extract could significantly improve the cell apoptosis in the retina caused by light, and the protective effect of aronia fruit extract on retinal light damage was also demonstrated by the TUNEL staining experiment ( Figure 4 in A-B, Table 3).

[0083] 2.6 Determination of plasma MDA level in mice

[0084] Collect mouse blood in an anticoagulant tube and centrifuge at 3000 RPM for 10 min at 4°C, then collect the upper plasma. Determine the content of MDA according to the method provided by the kit manufacturer.

[0085] Plasma malondialdehyde (MDA) is one of the main products of cell membrane lipid peroxidation. The content of MDA can be used as an index of lipid peroxidation to reflect the degree of cell membrane lipid peroxidation. The results are as Figure 5 shown in Table 3, indicating that light causes an increase in the level of lipid peroxidation in the model mouse group, while the high dose of Aronia melanocarpa fruit extract can significantly reduce the level of lipid peroxidation in vivo, suggesting its protective effect on cell oxidative stress damage.

[0086] 2.7 Determination of the level of interleukin-6 (IL-6) in mouse plasma

[0087] Take the centrifuged mouse plasma and determine the level of IL-6 according to the method provided by the kit manufacturer. The specific steps are as follows: Transfer various reagents to room temperature and equilibrate for at least 30 min, prepare the reagents according to the method provided by the kit manufacturer and set aside; Set up standard wells and test sample wells respectively, and add 100 μL of standard or serum to each well; Add 50 μL of "detection antibody working solution" to each test well; Seal the plate with a sealing film and incubate with shaking at 28°C for 1.5 h; After incubation, wash, add enzyme, substrate chromogenic solution and stop solution in sequence, and measure the OD value with an enzyme-linked immunosorbent assay (ELISA) reader within 30 min after the reaction stops.

[0088] Interleukins are a class of cytokines produced by various cells and acting on various cells, which are cytokines with important regulatory functions. They play an important role in transmitting information, activating and regulating immune cells, mediating the activation, proliferation and differentiation of T and B cells, and in inflammatory reactions. The results are as Figure 6 shown in Table 3, indicating that light causes an increase in the level of inflammation in the model mouse group, while both the low dose and high dose of Aronia melanocarpa fruit extract can significantly reduce the level of inflammation in vivo, suggesting that Aronia melanocarpa fruit extract has a protective effect on cell inflammatory reactions.

[0089] Although the above embodiments have described the present invention in detail, they are only a part of the embodiments of the present invention, not all of them. People can also obtain other embodiments based on these embodiments without creative efforts, and these embodiments all fall within the protection scope of the present invention.
