To investigate the mechanism of Jianpi Yishentongqiao granule (JPYSTQG) in the intervention of spleen-kidney Yang deficiency type allergic rhinitis (AR) rats based on metabolomics.
The AR rat model of spleen-kidney-yang deficiency type was constructed by ovalbumin intraperitoneal injection sensitization + hydrocortisone intraperitoneal injection + rhubarb irrigation combined with modeling, and was randomly divided into model group and experimental group, with 10 rats in each group. Another 10 normal rats were selected as blank group. The experimental group was given 472.5 mg·mL-1 JPYSTQG solution, the blank group and model group were given equal volume 0.9% NaCl. The rats in the three groups were administrated by gavage three times a day for 14 days. Serum levels of interleukin-4 (IL-4), immunoglobulin E (IgE) and interferon-γ (IFN-γ) were detected by enzyme-linked immunosorbent assay. Differential metabolites were screened by metabolomics and enriched by Kyoto Encyclopedia of Genes and Genomes.
The serum IgE levels in experimental, model and blank groups were (21.23±0.40), (23.80±0.67) and (20.03±1.42) ng·mL-1; IL-4 levels were (111.00±5.86), (119.79±7.07) and (99.24±1.03) pg·mL-1; IFN-γ levels were (1 980.63±15.63), (1 602.50±50.00) and (2 136.88±315.63) mg·mL-1, respectively. Compared with the model group, the differences of experimental and blank groups were statistically significant (all P<0.01). Thirty-seven potential biomarkers of JPYSTQG intervention in spleen-kidney-yang deficiency rats were screened, mainly through arginine biosynthesis and tumor-related pathways.
JPYSTQG can regulate the expression of cytosine and other substances through arginine metabolism pathway, reduce IL-4, IgE and other inflammatory indicators, and thus have therapeutic effect on the allergic rhinitis rats with spleen-kidney-yang deficiency.
