Detailed Description
The technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments, however, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step are within the scope of protection of the present invention.
Example 1: preparation of yolk distillation oil carbon dots
The purchased egg yolk powder of the same batch is weighed and then put into a crucible. Covering the opening of the crucible with aluminum foil paper, covering the cover tightly, and putting the crucible in a muffle furnace for carbonization.
The muffle furnace heating process comprises the following steps: heating to 260 ℃, wherein the heating process lasts for 1h, and the heating process lasts for 1 h; and opening the furnace door after the temperature is reduced to the room temperature, and taking out the crucible, wherein the product in the crucible is the yolk distilled oil.
The carbon point purification steps of the egg yolk distillation oil are as follows: the yolk oil was extracted three times with deionized water, filtered through a 0.22 μm microfiltration membrane and concentrated. Then using deionized water as dialysis medium, dialyzing the concentrated solution with 1000D dialysis membrane for 7 days, and taking out the solution in the bag, namely the carbon point of the egg yolk distillation oil.
Example 2 investigation of Fuchu oil charcoal Point eczema-alleviating Effect
SPF grade ICR mice 42, randomly divided into 6 groups, each group of 7, were blank group, 2, 4-Dinitrochlorobenzene (DNCB) induced chronic eczema model group, compound dexamethasone acetate cream positive drug control group, EYO-CDs low 10.8(g/ml), medium 21.6(g/ml), high 43.2(g/ml) dose group. The abdomen of the mice was dehaired 2X 2cm the day before the experiment. Except for the blank group, mice in each of the other groups were sensitized by applying 100. mu.L of 7% DNCB alcohol solution to the abdominal hair removal area on the 1 st day of the experiment. On day 5, the mice were challenged with 10. mu.L of 1% DNCB alcohol solution evenly in the right ear, lateral ear, and abdominal depilatory, 4 times every other day thereafter. After the initial excitation for 24 hours, the right ear of each group of mice is administrated on the front and back sides, the blank group and the model group are administrated with 10 mu L of physiological saline, the positive medicine group is administrated with 20 mg/ear of compound dexamethasone acetate cream, and the EYO-CDs group is administrated according to low dose, medium dose and high dose, each 10 mu L, and the administration is carried out once every other day for 4 times. Blood was collected from the eyeball 24 hours after the last administration, and then the mice were sacrificed, and both ears were excised and examined for the corresponding indices. And (3) carrying out eye ball picking and blood taking 24 hours after the last administration, then killing the mice, standing the blood for half an hour, centrifuging for 15min at 3000r/min, taking the supernatant, and detecting IL-4 and IFN-gamma in the blood according to the requirements of an ELISA kit. The punch cuts the tissues at the same positions in the middle of the two ears, the weight is weighed, the thickness is measured by a micrometer caliper, and finally the tissues of the right ear are fixed in 10 percent paraformaldehyde, embedded in paraffin, HE stained and observed under 200 light microscope. Cutting all tissues of the left auricle, rinsing with normal saline, wiping, weighing, adding 9 times of normal saline, grinding with a tissue triturator, centrifuging at 3000r/min for 10min, and taking the supernatant. According to the requirements of the kit, IL-4 and IL-17 in the mouse ear tissue homogenate are detected.
EYO-CDs measurement of thickness and weight of the right ear of chronic eczema mice (see Table 1): after 4 times of administration, compared with a model group, the positive medicine group has obvious reduction on the swelling thickness difference and weight difference of the right ear and the left ear of a mouse, compared with the model group, EYO-CDs dosage groups have reduction on the swelling thickness difference and weight difference of the right ear and the left ear of the mouse in different degrees, and a certain dose-effect relationship exists, so that the higher the concentration is, the better the effect of reducing the swelling thickness and the weight of the ears is. Compared with the model group, the difference of each group has statistical significance (P is less than 0.05 or P is less than 0.01).

Comparison with model groups: p < 0.05, P < 0.01
The detection results of the concentration levels of IL-4 and IFN-gamma in the serum of each group of mice (see Table 2): compared with the model group, the IL-4 content in the serum of mice of each dose group of the positive drug group and EYO-CDs is reduced to different degrees (P is less than 0.01), compared with the model group, the IFN-gamma content in the positive drug group, EYO-CDs and the high dose group is improved to different degrees (P is less than 0.01), and the low dose group has no obvious difference (P is more than 0.05). Compared among treatment groups, the serum IL-4 content of EYO-CDs high, medium and low dose mice is higher than that of the positive drug group, and the IFN-gamma content is lower than that of the positive drug group (P is less than 0.01), but a certain dose-effect relationship exists, and the higher the concentration of EYO-CDs group is, the higher the IL-4 reduction degree and the IFN-gamma increase degree are.

EYO-CDs histopathological results on ear skin of chronic eczema mice: FIG. 2 shows that the ear skin tissue structure of the blank group of mice is normal, the epidermis thickness is normal, no edema exists, no obvious lymphocyte infiltration exists, and the blood vessel morphology is normal. The chronic eczema model group mice have the advantages of ear epidermal necrosis, stratum granulosum thickening, acanthosis thickening, intracellular and intercellular edema, a large number of inflammatory cells in dermis, lymphocyte infiltration and obvious dermal blood vessel dilatation and congestion. The positive drug group mice have normal epidermis structures and slight keratinization, the edema of epidermis and dermis is obviously reduced, and inflammatory cells are obviously reduced. EYO-CDs low dose group had slightly reduced epidermal keratinization, edema and inflammatory cell infiltration, EYO-CDs medium dose group had slightly reduced epidermal keratinization, clear structure, significantly reduced inflammatory factors, and slight edema. EYO-CDs high dose group ear tissue epidermis structure is normal, keratinization is reduced obviously, edema, lymphocyte infiltration are reduced greatly, thickening degree is reduced obviously, blood vessel morphology is normal. It shows that EYO-CDs have good effect of treating eczema.
