Abstract:
OBJECTIVE：To study the mechanism of H uanglian jiedu decoction （HJD）regulating macrophage polarization in order to explore its anti-inflammatory mechanism. METHODS ：The active components and predicted targets of HJD were screened through TCMSP and Swiss Target Prediction database ；the related targets of macrophage polarization were obtained by GeneCards and OMIM database ，and the network diagram of active ingredient-macrophage polarization target of HJD was drawn by using Cytoscape 3.6.0 software；protein interaction network was constructed by String database and core targets were extracted. Gene ontology（GO）enrichment analysis and Kyoto Encyclopedia of genes and genomes （KEGG）pathway enrichment analysis were carried out by using Cytoscape 3.6.0 software and DAVID website. Combined with the results of network pharmacology analysis ， RAW264.7 macrophage cells were divided into blank control group ，model group ，simvastatin group （10 μmol/L）and serum containing HJD group （obtained from the blood after the rats were given HJD at the dose of 10 g/kg）. Except the blank control group and model group were added culture medium ， the other groups were added with 100 μ L of relevant drug solution or serum containing drug. After 2 h of culture ，except for the blank control group ，LPS solution （100 μg/L）was added to the other groups for 24 h to induce inflammation. Western blot assay was used to detect the expression of AMPK. mRNA expression of M 1 type polarization factor （IL-1 β，iNOS）and M 2 type polarization factor （IL-10，Fizz1）were detected by RT-PCR. RESULTS ：A total of 50 active components of HJD （such as acacetin ，wogonin，quercetin，β-sitosterol）were screened ， which could regulate macrophage polarization through 12 GO items （such as anoikis ，astrocyte activation ），and 20 KEGG pathways（such as estrogen signaling pathway ，bladder cancer pathway ，AMPK signaling pathway ）. The results of cell test showed that compared with blank control group ，the expression of AMPK protein ，Fizz1 and IL- 10 mRNA in model group were significantly decreased （P＜0.01），while the expression of IL- 1β and iNOS mRNA were significantly increased（P＜0.01）； compared with model group ，the expression of AMPK protein ，Fizz1 and IL- 10 mRNA in serum containing HJD group and simvastatin group were significantly increased （P＜0.05 or P＜0.01），while the expression of IL- 1β and iNOS mRNA were significantly decreased （P＜0.01）. CONCLUSIONS ：HJD can regulate macrophage polarization through multiple targets and pathways；it can up regulate the expression of M 2-type polarization factors and down-regulate the expression of M 1-type polarization factors through AMPK signaling pathway ，regulate macrophage polarization and play an anti-inflammatory role.
