OBJECTIVE: formula combined with prednisone on immune function and the ST2/IL-33 pathway in mice with immune thrombocytopenia. METHODS: formula + prednisone group (0.2 ml/10 g), 8 mice in each group, and the other 8 mice were set as control group. The drugs were administered by gavage at the dose, and the model group and control group were given equal amounts of saline by gavage once a day for 2 weeks of continuous intervention. Blood samples and spleen tissues were collected, the peripheral platelet count was measured by automatic hematology analyzer, the pathological changes in spleen tissue was observed by HE staining, the levels of serum transforming growth factor (TGF)-β, interleukin (IL)-17, and peripheral blood thrombopoietin (TPO) were detected by enzyme-linked immunosorbent assay (ELISA), the expression of IL-33, sST2, and ST2 in spleen tissue was detected by Western blot, and the cell counts of peripheral blood Th17 and Treg were detected by flow cytometry. RESULTS: <0.01). CONCLUSION: formula + prednisone can effectively regulate Th17/Treg balance, thus effectively improve immune thrombocytopenia, and the mechanism may be related to the regulation of ST2/IL-33 signaling pathway.
