Changes in serum TNF-α and IL-33 expression levels before and after treatment in the two groups of patients. A) Changes in serum TNF-α expression level before and after treatment in the two groups. There was no significant difference in serum TNF-α level between INF group (28.427±7.138) and MTX group (27.892±6.427) before treatment. While it decreased significantly after treatment in the two groups, and the serum TNF-α level in INF group (12.146±5.752) was significantly lower than that in MTX group (18.248 ±13.426). B) Changes in serum IL-33 expression level before and after treatment in the two groups. No significant difference was found in serum IL-33 level between INF group (261.152±28.443) and MTX group (256.763±26.976) before treatment. While the level of serum IL-33 dropped notably in the two groups after treatment, and the serum IL-33 level in INF group (121.274±13.426) was remarkably lower than that in MTX group (137.582±16.223) (P<0.001). *** indicated P<0.001.
