Objective: To study on the changes of endogenous metabolites in the urine of rats with myocardial ischemia reperfusion injury(MIRI) after administrating Roudoukou-8 San
in order to explore the pathogenesis of MIRI and the mechanism of drug pre-protection. Method: Rats were randomly divided into the sham-operated group[0.5% sodium carboxymethylcellulose(CMC-Na) solution
10 mL·kg -1]
the model group(0.5% CMC-Na
10 mL·kg -1) and the Roudoukou-8 San group(5.4 mg·kg-1).The urine metabolites of these three groups were characterized by UPLC-Q-Exactive-MS technique.Multivariate statistical analysis was performed by SIMCA 14.1 software to screen potential biomarkers. Result: After orthogonal partial least squares discriminant analysis(OPLS-DA)
the model group was significantly separated from the sham-operated group and the Roudoukou-8 San group
partial areas of the Roudoukou-8 San group overlapped with and the sham-operated group.Eight biomarkers related to MIRI were screened and they correlated with amino acid metabolism and fatty acid metabolism. Conclusion: Roudoukou-8 San can effectively regulate the imbalance of amino acid metabolism and fatty acid metabolism related to urine metabolism in MIRI model rats and preliminarily protect MIRI through multiple pathways.
