OBJECTIVE:

To study the mechanism of naoxintong capsule (NXT) -inhibiting peripheral ischemic inflammation.

METHODS:

Mice were randomly double-blindly divided into 3 groups: sham-operation group, model group and NXT group. Both model and NXT groups underwent the hind limb ischemia (HLI) surgery followed by oral gavage with saline or NXT, respectively, one hour after operation. Three days after operation, the percentages of neutrophils and macrophages in the gastrocnemius muscle were examined by flow cytomety and immunohistochemical method. The changes in gene and protein expressions induced by NXT were examined by real-time PCR and protein chip, respectively. The changes of signaling pathways were analyzed.

RESULTS:

Compared with sham oparation and model groups, NXT could decrease the ratios of neutrophils and macrophages in gastrocnemius inflammation site (P<0.01), and downregulate the mRNA expression of gene EMR1 (P<0.01). NXT reduced the expression of TNF-α and IL-1ß at both mRNA (P<0.001) and protein levels (P<0.05). The proteomic analysis showed that the use of NXT resulted in the expression changes of 13 proteins. The expression of 6 cytokines was increased, and the secretion of 7 proteins was upregulated. Besides, most of identified 13 proteins were involved in the function regulation of other immune cells.

CONCLUSION:

NXT can significantly alleviate ischemia-induced peripheral inflammation by reducing the ratio of immune cells and altering the expression patterns of mRNA and protein. The expression changes provide theoretical guidance and the potential targets for the clinical use of NXT in the treatment of ischemia-induced peripheral inflammatory diseases.
