Description

Technical Field

[0001] This invention relates to the field of pharmaceutical technology, and more specifically to a composition and its use in anti-inflammatory applications. Background Technology

[0002] Inflammation is a common disease, and many factors, such as ultraviolet radiation, can lead to inflammation, including dermatitis. During inflammation, the levels of inflammatory factors, such as interleukin-6, often increase. If inflammation is not effectively treated, it can cause various adverse reactions. Common symptoms of dermatitis include erythema, itching, redness and swelling, fever, mild hyperplasia of skin lesions, lichenification, and pigmentation, thus negatively impacting the body. Therefore, effective prevention and treatment of inflammation, such as reducing inflammatory factor levels, has always been a key focus in clinical practice. However, current technology lacks a method that can effectively prevent and treat inflammation, making the development of an effective anti-inflammatory method a current research hotspot.

[0003] Therefore, there is a need in this field to develop an anti-inflammatory method. Summary of the Invention

[0205] DMEM medium: DMEM basal medium + 10% FBS + 1% penicillin-streptomycin solution.

[0206] 2.1 Experimental Methods and Results

[0207] The following groups were set up: a control group, a model group, experimental group A, experimental group B, experimental group C, experimental group D, experimental group E, experimental group F, and experimental group G. HaCaT cells (human immortalized keratinocytes) in the logarithmic growth phase were collected from each group at a concentration of 2 × 10⁻⁶ cells / mL. 6 Cells were seeded at a density of cells / mL onto multi-well cell culture plates, with 1 mL of cell suspension added to each well. The plates were incubated overnight at 37°C and 5% CO2, then the culture medium was discarded. Finally, 1 mL of the following drug was added to each well for treatment:

[0208] Control group: DMEM medium;

[0209] Model group: DMEM medium;

[0210] Experimental group A: DMEM medium dispersion of Paris polyphylla extract, wherein the concentration of Paris polyphylla extract is 2.5 μg / mL;

[0211] Experimental group B: DMEM medium dispersion of Panax notoginseng extract, wherein the concentration of Panax notoginseng extract is 1.0 mg / mL;

[0212] Experimental group C: Aloe vera extract dispersion in DMEM medium, wherein the concentration of aloe vera extract is 5 mg / mL;

[0213] Experimental group D: DMEM medium dispersion of Paris polyphylla extract and Panax notoginseng extract, wherein the concentration of Paris polyphylla extract was 2.5 μg / mL and the concentration of Panax notoginseng extract was 1.0 mg / mL;

[0214] Experimental group E: DMEM medium dispersion of Paris polyphylla extract and Panax notoginseng extract, wherein the concentration of Paris polyphylla extract was 2.5 μg / mL and the concentration of Panax notoginseng extract was 0.1 mg / mL;

[0215] Experimental group F: DMEM medium dispersions of Paris polyphylla extract, Panax notoginseng extract and Aloe vera extract, wherein the concentration of Paris polyphylla extract was 2.5 μg / mL, the concentration of Panax notoginseng extract was 1.0 mg / mL and the concentration of Aloe vera extract was 5 mg / mL.

[0216] Experimental group G: DMEM medium dispersions of Paris polyphylla extract, Panax notoginseng extract and Aloe vera extract, wherein the concentration of Paris polyphylla extract was 2.5 μg / mL, the concentration of Panax notoginseng extract was 0.1 mg / mL and the concentration of Aloe vera extract was 5 mg / mL.

[0217] Each group was repeated three times. After drug administration, each group was incubated at 37°C and 5% CO2 for 6 hours. Then, except for the control group, all other groups were subjected to the same UVA ultraviolet radiation (9 J / cm²). 2 After UV radiation treatment, each group was cultured for another 24 hours. Then, the culture medium was removed from each well, and the cells were washed with PBS 7.4 buffer. 400 μL of cell lysis buffer (prepared at a RIPA:PMSF ratio of 100:1) was added to each well to lyse the cells. The cells were then centrifuged at 10000 rpm at 4°C for 5 minutes, and the supernatant was collected. The total protein content in the cell lysis supernatant was determined using the BCA (Bicinchoninic acid) method, and the IL-6 (interleukin-6) content in the cell lysis supernatant was detected using an ELISA kit (Cloud-Clone Crop). The IL-6 (interleukin-6) content in the cell lysis supernatant of each group is shown below. Figure 1 As shown in Table 1.

[0219]

[0220] Note: Except for the control group, all other groups were stimulated with the same UVA ultraviolet light (9J / cm²). 2 ).

[0221] from Figure 1As shown in Table 1, compared with the model group, the Paris polyphylla extract, Panax notoginseng extract, and Aloe vera in Example 1 effectively reduced the content of the inflammatory factor IL-6, thus exhibiting excellent anti-inflammatory effects. Specifically, compared with the reduction of IL-6 content by Paris polyphylla extract and Panax notoginseng extract alone in experimental groups A and B, the combined use of specific amounts of Paris polyphylla extract and Panax notoginseng extract in experimental group D showed a synergistic effect in reducing IL-6 content. Therefore, the combined use of specific amounts of Paris polyphylla extract and Panax notoginseng extract in experimental group D had a synergistic effect in anti-inflammation, thereby significantly improving the anti-inflammatory effect.
