Blood stasis syndrome (BSS) is one of the most common Chinese medicine patterns in coronary heart disease. Our previous work proved that Xueshuan Xinmaining Tablet (XXT) could treat blood stasis through regulating the expression of F13a1, Car1 and Tbxa2r. In the current study, the effect and mechanism of XXT on BSS was comprehensively and holistically investigated based on a metabolomics approach. Urine and plasma samples of 10 BBS rats treated with XXT (XT), 9 BSS model rats (BM) and 11 normal control (NC) rats were collected and then determined by UPLC-Q/TOP-MS. Multivariate analyses were applied to distinguish differentiate urinary and plasma metabolite patterns between three groups. Results showed that a clear separation of three groups was achieved. XT group was located between BM group and NC group, and showing a tendency of recovering to NC group, which was consistent with the results of hemorheological studies. Some significantly changed metabolites like cortexolone, 3α,21-dihydroxy-5β-pregnane-11,20-dione and 19S-hete and leukotriene A4, chiefly involved in steroid hormone biosynthesis, arachidonic acid metabolism and lipid metabolism, were found and identified to explain the mechanism. These potential markers and their corresponding pathways will help explain the mechanism of BSS and XXT treatment. This work also proves that metabolomics is effective in traditional Chinese medicinal research.Keywords:blood stasis syndrome;Xueshuan Xinmaining tablet;UPLC-Q/TOF-MS;rats;metabolomics

Background : Specific treatment for rheumatoid arthritis (RA) is still an unmet need. Yu-Xue-Bi (YXB) capsule effectively treats RA with blood stasis syndrome (BS). However, its mechanism remains unclear. Purpose : Exploring and elucidating the therapeutic effect and pharmacological mechanism of YXB capsule in treating RA. Methods : This study identified differentially expressed genes (DEGs) in patients with RA and BS compared to healthy controls using clinical transcriptomics data. Clinical symptoms of RA and BS, and the related genes were collected from the SoFDA and HPO databases. Candidate bioactive constituents in YXB were identified via UPLC-QTOF/MS and evaluated using ADMET rules. Putative targets were predicted, and a network linking disease-related DEGs and drug targets was constructed. Key targets were screened utilizing random walk-with-restart (RWR) algorithms and verified through experiments using rat models of collagen-induced arthritis with BS (CIA-BS model) in vivo . Results : We found 1220 DEGs along with 976 clinical symptom-related genes, as RA with BS-related genes. Chemical profiling identified 193 YXB constituents, with 98 meeting optimal ADMET criteria. We predicted 459 putative targets for these constituents. Network calculations screened 209 key targets, 129 RA with BS-related genes and 92 YXB targets involved in immune inflammation, blood stagnation, and hyperalgesia imbalance. Notably, the SUCNR1/HIF-1α/TRPV1 axis was enriched by YXB targets against RA with BS. Experimentally, YXB inhibited inflamed joint deterioration, including synovial inflammation, cartilage damage and bone erosion, relieving mechanical and cold allodynia hyperglasia. It reversed hemorrheology and vascular function in CIA-BS rats, restoring SDHB and eNOS expression, preventing SDHA, SUCNR1 and HIF-1α activation, reducing SUCN, TNF-1α and IL-1β production, and TRPV1 and TRPA1 expression. Conclusion : Our data support YXB's therapeutic effects on aggressive RA-BS by modulating the SUCNR1/HIF-1α/TRPV1 axis.

Ethnopharmacological relevance Rubia cordifolia is a common traditional Chinese medicine that promotes blood circulation and eliminates blood stasis , and has been used to cure diseases related to blood stasis syndrome (BSS) clinically for many years. It has been previously demonstrated that anti-thrombosis and pro-angiogenesis can improve BSS. However, the anti-thrombotic and pro-angiogenic activities of Rubia cordifolia have not been well investigated. Aim of study To determine the potential anti-thrombotic and pro-angiogenic activities of Rubia cordifolia and to elucidate the underlying mechanisms. In addition, the major chemical constituents of Rubia cordifolia extract (QC) were qualitatively analysed by UPLC-Q-TOF/MS to explore the association between pharmacological activity and chemical constituents. Material and methods The QC samples were composed of a 95% ethanol extract and an aqueous extract following extraction using 95% ethanol. UPLC-Q-TOF/MS was used to analyse the major chemical constituents of QC. For the anti-thrombotic experiment of QC, a phenylhydrazine (PHZ)-induced AB strain zebrafish thrombosis model was used. The zebrafish larvae were stained using O-dianisidine, and the heart and caudal vein of the zebrafish were observed and imaged with a fluorescence microscope. The staining intensity of erythrocytes in the heart (SI) of each group and the morphology of thrombus in the caudal vein were used to assess the anti-thrombotic effect of QC. For the pro-angiogenic assay of QC, the intersegmental blood vessel (ISV) insufficiency model of Tg(fli-1: EGFP)y1 transgenic zebrafish (Flik zebrafish), which was induced by the VEGF receptor tyrosine kinase inhibitor II (VRI), was used. The morphology of the intact ISVs and defective ISVs was observed to evaluate the pro-angiogenic activity of QC. The mechanism involved in promoting angiogenesis was studied with real-time PCR. Results A total of 12 components in QC were identified based on standard compounds and references, including nine anthraquinones and three naphthoquinones . After treatment with QC, the PHZ-induced thrombosis in AB strain zebrafish larvae decreased to a certain degree, which we believe was related to its dosages, and the therapeutic effect within the 50–200 µg/mL QC treatment groups was especially prominent (P < 0.01, P < 0.001) compared to that in the PHZ model group. Similarly, QC also recovered the loss of the ISVs, which was induced by VRI in Flik zebrafish larvae, which have a certain dose-effect relationship. The pro-angiogenic activity of QC was also conspicuous (P < 0.01, P < 0.001) compared to that of the VRI model group. The following real-time PCR assay proved that QC significantly restored the VRI-induced downregulation of vWF, VEGF-A, kdrl, and flt-1 in Flik zebrafish (P < 0.05, P < 0.01, P < 0.001). Conclusions A total of 12 compounds from QC were analysed by UPLC-Q-TOF/MS. The data of the pharmacological experiments demonstrated that QC presented anti-thrombotic and pro-angiogenic activities in zebrafish, and the principal active components were likely anthraquinones and naphthoquinones. Thus, the current study provided a theoretical basis for the clinical use of Rubia cordifolia as a traditional Chinese medicine in promoting blood circulation and eliminating stasis.

Ethnopharmacological relevance As a traditional Chinese medicine , raw Moutan Cortex (RMC) has been used in clinical practice for thousands of years. However, its blood-cooling and blood-activating medicinal effects as well as the underlying mechanisms have not been preliminarily verified until recent years. Aim of the study Our group's previous network pharmacological studies suggested that RMC might exert its blood-activating and anti-inflammatory effects by modulating the coagulation-inflammation cascade pathway. Therefore, the present study aimed to further investigate the mechanisms relevant to the blood-activating and anti-inflammatory effects of RMC so as to provide more robust data supporting its clinical application. Materials and methods The inflammation and coagulation models of human umbilical vein endothelial cells (HUVECs) were induced by TNF-α; The rat models with blood-heat and blood-stasis syndrome (BHS) were constructed by ice-water bath with a combined use of epinephrine hydrochloride and dried yeast; The thrombus models of zebrafish were induced by arachidonic acid , and the inflammation models were established using LPS and CuSO 4 . The regulatory effects of RMC on the key targets in the pathway of the coagulation-inflammation cascade were investigated by combining ELISA , RT-PCR, and western blot techniques in an attempt to provide multiple validations concerning RMC's pharmacological efficacy and mechanism associated with cooling blood and activating blood circulation. Result The findings from the pharmacodynamic research demonstrated that RMC could inhibit the coagulation and inflammation process of HUVECs. Besides, it lowered the anal temperature and whole blood viscosity in BHS rats in addition to a prolongation of their prothrombin time (PT), thrombin time (TT), and activated partial thromboplastin time (APTT). Successfully constrained thrombotic area and reduced inflammatory cell counts were also observed in zebrafish models. Meanwhile, ELISA, RT-PCR and WB showed that RMC were capable of inhibiting the factors related to coagulation-MARK inflammation pathway—FⅡ, TF, FⅦ, FⅧ, FⅩ, and PAI, as well as down-regulating the expression of IL-6, COX-2, iNOS, TNF-α, ERK, JNK and p38. Conclusion RMC exerts blood-activating and anti-inflammatory effects through regulating the target genes of the coagulation-MARK inflammation cascade pathway.
