Study on the inhibition effect and mechanism of Shugan Jieyu Decoction on rats with acute mastitis

Objective To investigate the effect of Shugan Jieyu Decoction on rats with mastitis.Methods SD rats were divided into a blank group,a model group,and the Shugan Jieyu Decoction low-,medium-and high-dose groups (2.5,5 and 10 mg/kg,respectively),with 10 rats in each group.Before modeling,the three experimental groups were given Shugan Jieyu Decoction by gavage,while the blank and model groups were treated with normal saline by gavage,all once a day.After 5 days,the rat LPS mastitis model was replicated,and the drug was administered once again 12 hours after modeling.The pathological changes of breast tissues were observed by HE staining 24 hours after modeling.The contents of IL-1,IL-6 and TNF-α in rat serum and breast tissues were detected by Elisa.The protein expression levels of p38,p-p38,MAPKAPK2 and p-MAPKAPK2 in breast tissues were detected by Western Blot.Results The breast tissues in the model group were seriously damaged,and the levels of IL-1,IL-6 and TNF-α in serum and tissues were significantly increased,and the protein expression levels of p-p38 and p-MAPKAPK2 in tissues were increased.In the experimental group,the damage of breast tissues was reduced,and the levels of IL-1,IL-6 and TNF-α in serum and tissues were decreased,and the protein expression levels of p-p38 and p-MAPKAPK2 in tissues were decreased (all P<0.05).Conclusion Shugan Jieyu Decoction can relieve acute mastitis,and reduce inflammatory factors in serum and tissues,possibly by inhibiting the p38 /MAPKAPK2 pathway.
