Abstract:
Liquid chromatography-mass spectrometry method was used for determination of metabolic fingerprint spectrum in rat serum, and the method of multivariate statistical analysis was used to compare the metabolism spectrum difference and screen significantly related biomarkers. The dynamic change trend was investigated at the same time. The dynamic metabonomics changes of liver injury in rats caused by Polygonum multifulorum(PM) were investigated; significantly related biomarkers were found and their dynamic change trend was investigated to provide basis for internal mechanism and early clinical diagnosis. There was certain difference in serum metabolic profile of the rats at different time points. Six potential biomarkers were screened through comparative analysis, including oleamide, lysoPC(16∶0), leukotriene A4, trans-tetra-dec-2-enoic acid, dihydrocortisol and 7a-hydroxydehydroepiandrosterone. These markers presented the dynamic change trend in the process of PM causing liver damage. The biomarkers contents had a significant change after one week of drug administration, more sensitive than ALT and AST. It can reveal the dynamic mechanism of PM causing liver damage and hepatic self-healing performance to some extent, with important application value and significance for monitoring liver function and early detecting diagnosis for patients with PM.
