    Abstract Background: Lagopsis supina (Steph. ex. Willd.) Ikonn.-Gal. is an important traditional Chinese medicine used to treat various ailments. However, its impact on myocardial ischemia (MI) injury remains unknown.
    Purpose: This research aimed to reveal the therapeutic effect, potential mechanism, and metabolomics of L. supina against MI injury in rats.
    Methods: The therapeutic effects of the ethanolic extract of L. supina (LS) and its four fractions (LSA∼D) on a left anterior descending (LAD) artery occlusion-induced MI model rat were explored. The pharmacodynamics including myocardial infraction area, myocardial tissue pathology and apoptosis, and serum biochemical parameters (CK, CK-MB, CTn-T, SOD, ET-1, NO, eNOS, VEGF, TXB2, 6-keto-PGF1α, TNF-α, IL-6, and CRP) were evaluated. The 24 related protein expressions were detected using western blotting assay. Simultaneously, the qualitative and quantitative analyses of microporous adsorption resin with 30% (LSC) and 60% (LSD) aqueous ethanol fractions were performed using UHPLC-MS and HPLC. Moreover, the serum metabolomics analysis of rats was profiled using UHPLC-MS.
    Results: LS exerted remarkable alleviating effect on MI in rats. Importantly, LSC and LSD, two effective fractions of LS, significantly reduced myocardial infraction area, alleviated myocardial tissue pathology and apoptosis, regulated serum biochemical parameters. Furthermore, LSC and LSD markedly up-regulated the levels of VEGF-A, VEGFR-2, PKC, Bcl-2, Nrf2, HO-1, and thrombin, as well as prominently down-regulated the protein expression of Notch 1, p-PI3K, p-PI3K/PI3K, p-Akt, p-Akt/Akt, Bax, cleaved-caspase-3, cleaved-caspase-3/caspase-3, vWF, p-Erk, p-Erk/Erk, HMGB1, p-p38, p-p38/p38, p-p65, and p-p65/p65. A total of 26 candidate biomarkers were significantly regulated by LSC and LSD and they are mainly involved in amino acid metabolism, glycerophospholipid metabolism, and sphingolipid metabolism. Finally, phenylethanols and flavonoids may be major bio-constituents of LSC and LSD against MI.
    Conclusions: This work, for the first time, demonstrated that L. supina had a significant therapeutic effect on MI in rats. Additionally, LSC and LSD, two bio-fractions from L. supina, exerted their potential to ameliorate MI injury by promoting angiogenesis, inhibiting thrombosis, blocking inflammation, and facilitating energy metabolism through promotion of VEGF pathway, as well as suppression of ROS and HMGB1 pathways in rats. These findings suggest that LSC and LSD hold promise as potential therapeutic agents for MI injury in clinical application.

    Abstract Hosta plantaginea (Lam.) Aschers flower is an important Mongolian medicine beneficial in the treatment of chronic prostatitis (CP) in the absence of scientific evidence. The aim of this study was to reveal the therapeutical effects and potential mechanisms of H. plantaginea flowers extract (HP) and its different polarity fractions (HPA∼D) on autoimmune CP (ACP) model rats. Sprague-Dawley male rats were randomly assigned to 13 groups (n = 6/group). Except the sham group, all rats were injected with a mixture of prostate antigen and complete Freund's adjuvant on days 0, 7, and 21 to establish ACP model rats. Afterwards, ACP model rats were orally gavaged with HP or HPA∼D (1 and 4 g/kg of raw herbal material) or positive drug (Prostat, 200 mg/kg) daily from day 21 to day 50 for 30 days, while the sham and model groups were treated simultaneously with isopyknic of 0.3% sodium carboxymethyl cellulose. Histopathological analysis, biochemical parameters, and protein expression of prostate tissues were investigated. In comparison with the model group, all fraction groups experienced improved CP effects, including restored body weight, reduced prostate gland edema and prostate index, decreased prostatic leukocytes, increased prostatic lecithin bodies, and alleviated histopathological damage to prostate tissue. Furthermore, all fraction groups markedly inhibited the phosphorylated protein of nuclear factor kappa-B p65 (NF-κB p65), NF-κB inhibitor alpha (IκBα), c-Jun N-terminal kinase (JNK), p38 mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinase (Erk), just another kinase 1 (JAK1), signal transducer and activator of transcription 3 (STAT3), phosphoinositide 3-kinase (PI3K), and protein kinase B (Akt) than the model group. All fractions of HP exerted significant anti-CP effects by inhibiting NF-κB, MAPKs, JAK-STAT and PI3K-Akt pathways in ACP model rats. These findings provide scientific evidence that H. plantaginea flowers can be used as a pivotal Mongolian medicine in clinical applications for the treatment of CP.
