Different concentrations of Chinese medicine Xiaoyingdaotan Decoction on Hashimoto’s thyroiditis mouse model
Abstract Background Through the detection of Notch/Treg/Th17 pathway related factors, to explore the effect of different concentrations of Chinese medicine Xiaoyingdaotan Decoction on Hashimoto's thyroiditis mouse model. Methods To make the mouse model of Hashimoto's thyroiditis, and to administer the Chinese medicine Xiaoyingdaotan Decoction of different concentrations by gavage. After the treatment, the expression of serum Notch protein and Treg/Th17 cytokine levels in mice were detected. The quantitative data conformed to the normal distribution with t test, and did not conform to the normal distribution with Wilcoxon rank sum test. Results The serum Notch protein expression of mice in the model group was significantly higher than that of the other groups, and the difference was statistically significant (P<0.001). Comparing the high-dose Chinese medicine group with the low-dose Chinese medicine group and the model group, the level of the key activation protein FOX-P3 in serum of Treg cells in mice was significantly increased, and the difference was statistically significant (P<0.05). Compared with the model group, the serum TGF-β levels of each group of traditional Chinese medicine were significantly higher than that of the model group, and the difference was statistically significant (P<0.05). The levels of key activating proteins STAT3, RORγt and IL-22 in serum of Th17 cells in each group of traditional Chinese medicine mice were significantly lower than those in the model group, with statistical differences (P<0.05). Conclusion Different concentrations of Chinese medicine Xiaoyingdaotan Decoction can down-regulate the expression of Notch protein in HT mouse model, and can effectively regulate Treg/Th17 cytokines.
