Metabolomic profiling of the effects of Curcumae rhizoma and Sparganii rhizome on stress-led blood stasis

Abstract

Blood stasis (BS) is a complex syndrome with blood flow retardation or cessation. The Traditional Chinese Medicine, Curcumae rhizome (CR) and Sparganii rhizome (SR), showed promising effects on this disease, and especially effective when used in combination. However, the detailed influence of the TCMs on the BSS disturbed metabolic pathways was still unclear. In this study, a BS model was constructed in SD rat and the TCMs were used individually or in combination to assess the effects. As a result, combination of CR and SR led to the improvement in hemorheology parameters of up to 80% in the BS model. Further analyzing using metabolomics showed several metabolic pathways, including center carbon metabolism, amino acid metabolism, etc., recovered to the normal levels after treatment. Informatively, tyrosine and thymidine exhibited potential importance in the BSS and its treatment process. From these results, the metabolic profiles of BS and the SR-CR treatment were provided, which may helpful for better understanding the BSS mechanism and the development of more effective therapies.
