AIM

The aim of this study was to explore the antipyretic effect and potential mechanism of Huanglian Jiedu Decoction (HLJDD) on LPS-induced fever in rats.

MATERIALS AND METHODS

The fever rat model was established by LPS. Anal temperature of rats was measured every 1 hour after modeling. TNF-, IL-6, PGE, and cAMP in rat serum or hypothalamus tissue were detected by ELISA kit. In order to explore the potential active ingredients and mechanism of antipyretic effect of HLJDD, we predicted the underlying antipyretic mechanism by using network pharmacology and then verified its mechanism by Western Blotting.

RESULTS

The results showed that HLJDD can alleviate LPS-induced fever in rats. The expression levels of TNF-, IL-6, PGE, and cAMP in the treatment group were significantly lower than those in the model group. Western Blotting results showed that the protein expression of p-ERK, p-JNK, and p-P38 was significantly inhibited.

CONCLUSION

The findings suggest that HLJDD has a good antipyretic effect on LPS-induced fever in rats, which may be closely related to the inhibition of MAPK signaling pathway.

目的

本研究旨在探讨黄连解毒汤（HLJDD）对脂多糖（LPS）诱导的大鼠发热的解热作用及潜在机制。

材料与方法

采用LPS建立发热大鼠模型。造模后每1小时测量大鼠肛门温度。用ELISA试剂盒检测大鼠血清或下丘脑组织中的肿瘤坏死因子-α（TNF-α）、白细胞介素-6（IL-6）、前列腺素E（PGE）和环磷酸腺苷（cAMP）。为探究HLJDD解热作用的潜在活性成分及机制，我们运用网络药理学预测其潜在解热机制，然后通过蛋白质印迹法进行验证。
