[0161] BJ cells were placed in DMEM high-glucose medium containing 10% fetal bovine serum and 1% double antibody and cultured in an environment of 37 °C and 5% carbon dioxide. When the cell growth state was good, RAW264.7 cells were inoculated into a 96-well plate at a density of 1×104 cells per well, and 150 μL of medium was added to each well and incubated at 37 °C for 24 h.

[0166] It can be seen from Table 1 that SPG at a concentration of 4 μg / mL to 120 μg / mL has no toxic effect on BJ cells and can be formulated with C3G within this concentration range.

[0167] Table 2 Effects of various concentrations in Example 2 on the survival rate of BJ cells

[0168]

[0169] It can be seen from Table 2 that C3G at a concentration of 0.16 μg / mL to 4 μg / mL has no toxic effect on BJ cells and can be formulated with SPG within this concentration range.

[0170] Experimental Example 2 Detection of Inflammatory Factor IL-1β Content (RT-qPCR Method)

[0171] Take BJ cells in good growth state and inoculate BJ cells into a 6-well plate at a density of 1×106 cells per well. Add 2 mL of culture medium to each well and incubate at 37 °C for 24 h.

[0172] The experiments were divided into a normal group, a model group, an SPG experimental group, a C3G experimental group, and an SPG + C3G (Examples 1 - 3).

[0173] Normal group: There are cells, no lipopolysaccharide (LPS), no SPG or C3G;

[0174] Model group: There are cells, there is LPS (10 μg / mL), no SPG or C3G;

[0175] SPG experimental group: According to the drug addition requirements, change the culture medium. After the drug acts for 2 h, add LPS with a final concentration of 10 μg / mL and continue to culture for 24 h, then collect the cells;

[0176] C3G experimental group: According to the drug addition requirements, change the culture medium. After the drug acts for 2 h, add LPS with a final concentration of 10 μg / mL and continue to culture for 24 h, then collect the cells;

[0177] SPG + C3G experimental group: According to the drug addition requirements, change the culture medium. After the drug acts for 2 h, add LPS with a final concentration of 10 μg / mL and continue to culture for 24 h, then collect the cells.

[0178] Use a nucleic acid extraction kit to extract the total RNA of the cells in each experimental group; and reverse transcribe it into cDNA; search for the human inflammatory factor IL-1β sequence and related information, synthesize primers by the company, and perform RT-PCR to detect the mRNA expression level of IL-1β in each group according to the kit steps, and calculate the relative expression level of the inflammatory factor IL-1β by the 2-△△Ct method.

[0179] The test results are shown in the following table and the accompanying drawings of the specification.

[0180] Table 3 Effects of different concentrations of SPG, CG3, and their combination on the relative expression level of IL-1β

[0181]

[0182] It can be seen from the test results in the above table that the relative expression level of the inflammatory factor IL-1β in the BJ cells of each example is lower than that of the model group. Thus, it can be shown that the solutions of the embodiments of the present application can effectively improve the anti-inflammatory effect.

[0183] Furthermore, by comparing different embodiments, it can be seen that when the ratio of the SPG+CG3 composition is 30:1, the relative expression level of the inflammatory factor IL-1β in BJ cells is 1.1, which is significantly lower than 3.2 in the model group and is the lowest among different ratios. This indicates that when the ratio of the SPG+CG3 composition is 30:1, the inhibitory effect on the inflammatory factor IL-1β in BJ cells is the best.

[0184] Instruction manual attachment Figure 1 is the dose-effect relationship curve of SPG, C3G and their combination inhibiting the expression of inflammatory factor IL-1β in BJ cells; Note: The drug mass concentration of the composition is plotted with the mass concentration of SPG in the combination.

[0185] It can be Figure 1 seen that the inhibitory rate of the combination of SPG and C3G on the expression of inflammatory factor IL-1β shows a dose dependence. And compared with the separate use of SPG and C3G respectively, when reaching the same IL-1β inhibitory rate, the concentration of the single drug in the SPG and C3G combination is significantly reduced, indicating its synergistic effect.

[0186] Experimental example 3 Analysis of the synergistic inhibitory effect of SPG, C3G and their combination on inflammatory factor IL-1β

[0187] The median-effect principle and the Chou-Talalay combination index method were used to determine the synergistic inhibitory effect of SPG, C3G and their combination on the expression of inflammatory factor IL-1β mRNA. According to the median-effect equation Fa / Fu=(D / Dm)m, the dosage of a single or two drugs at a specific inhibition rate was calculated. The median-effect equation was transformed into a linear equation log(Fa / Fu)=mlogD-mlogDm, where D represents the drug dosage, Fa represents the fractional inhibition rate, Fu = 1 - Fa, Dm is the median concentration, representing the drug concentration at 50% effect, and m is the slope of the straight line of the linear equation.

[0188] According to the Chou-Talalay equation (CI=(D1) / (Dx1)+(D2) / (Dx2)), the combination index (CI) of Schizophyllan β-glucan and cyanidin-3-O-glucoside was calculated. D1 and D2 are the respective concentrations of the SPG and C3G combination at the X drug effect (inhibitory rate of inflammatory factor IL-1β mRNA expression), and Dx1 and Dx2 are the concentrations of SPG and C3G when used alone to achieve the above X drug effect. The synergistic inhibitory effect of the two on the expression of inflammatory factor IL-1β mRNA was evaluated. When CI < 1, the combined effect of the two drugs is a synergistic effect; when CI = 1, the combined effect of the two drugs is an additive effect; when CI > 1, the combined effect of the two drugs is an antagonistic effect.

[0189] The test results are shown in the instruction manual attachment Figure 2 and Table 4.

[0190] Figure 2 It is a graph of the inhibition rate - combination index (Fa - CI) of the composition of SPG and C3G under the compatibility of a mass concentration ratio of 30:1.

[0191] Table 4 Drug dosage table of SPG, C3G and their composition (30:1) when the inhibition rate of IL - 1β, Fa = 0.5

[0192]

[0193] From Figure 2 and Table 4, it can be seen that when the mass concentration ratio is 30:1 and within a certain concentration range, the CI value of the composition of SPG and C3G is less than 1, and it has an obvious synergistic effect on the expression of the inflammatory factor IL - 1β in BJ cells, and can significantly reduce the single - drug dosage.

[0194] The above - mentioned are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
