PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 132:155879. [PMID: 39032277 DOI: 10.1016/j.phymed.2024.155879] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Revised: 05/27/2024] [Accepted: 07/13/2024] [Indexed: 07/23/2024]
Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) and the consequent right heart dysfunction persist with high morbidity and mortality, and the mechanisms and pharmacologic interventions for chronic right-sided heart failure (RHF) have not been adequately investigated. Research has shown that prolonged inflammation is critical in precipitating the progression of PAH-associated right heart pathology. Some research demonstrated that Lingguizhugan decoction (LGZGD), as a classical Chinese medicine formula, had beneficial effects in alleviating PAH and RHF, while its underlying mechanisms involved are not fully elucidated. PURPOSE Based on that, this study aims to investigate the effects and underlying mechanisms of LGZGD on PAH-induced RHF. STUDY DESIGN In this study, we identified the serum constituents and deciphered the potential anti-inflammatory mechanism and crucial components of LGZGD using combined approaches of UPLC-HRMS, transcriptomic analysis, and molecular docking techniques. Finally, we used in vivo experiments to verify the expression of key targets in the monocrotaline (MCT)-induced RHF model and the intervene effect of LGZGD. RESULTS Integrated strategies based on UPLC-HRMS and systems biology approach combined with in vivo experimental validation showed that LGZGD could improve right heart fibrosis and dysfunction via regulating diverse inflammatory signaling pathways and the activity of immune cells, including chemokine family CCL2, CXCR4, leukocyte integrins family ITGAL, ITGB2, and M2 macrophage infiltration, as well as lipid peroxidation-associated HMOX1, NOX4, and 4-HNE. CONCLUSION The present research demonstrated for the first time that LGZGD might improve PAH-induced RHF through multiple anti-inflammatory signaling and inhibition of ferroptosis, which could provide certain directions for future research in related fields.

Tao S, Yu L, Li J, Shao M, Yang D, Wu J, Xue T, Huang X. Comparative efficacy of eight oral Chinese patent medicines for dilated cardiomyopathy with heart failure: a Bayesian network meta-analysis. Syst Rev 2024; 13:222. [PMID: 39217375 PMCID: PMC11365150 DOI: 10.1186/s13643-024-02582-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Accepted: 06/10/2024] [Indexed: 09/04/2024] Open
Abstract
BACKGROUND Chinese patent medicines (CPMs) are widely used in China as an adjuvant treatment in dilated cardiomyopathy with heart failure (DCM-HF). However, comprehensive and systematic evidence supporting the beneficial effects of CPMs combined with current complementary and alternative medicine (CAM) treatments against DCM-HF was limited. This network meta-analysis (NMA) aimed to assess and rank the relative efficacy of eight different CPMs for DCM-HF. METHODS To retrieve randomized controlled trials (RCTs) focusing on the use of CPMs combined with CAM for DCM-HF, the databases of PubMed, Embase, Web of Science Core Collection, Cochrane Library, ProQuest, China National Knowledge Infrastructure (CNKI), China Science Periodical Database (CSPD), Chinese Citation Database (CCD), Chinese Biomedical Literature Database (CBM), and ClinicalTrials.gov were comprehensively searched from their inception to 29 February 2024. The quality of the included RCTs was examined using the Cochrane Risk of Bias assessment tool, version 2.0 (RoB 2). Surface under the cumulative ranking curve (SUCRA) probability values were applied to rank the relative efficacy. Bayesian network meta-analysis was designed to assess the efficacy of different CPMs. RESULTS After applying the inclusion and exclusion criteria, a total of 77 eligible RCTs involving 6980 patients were enrolled. The outcomes assessed included clinical effectiveness rate (CER), left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDD), 6-min walk test (6MWT), brain natriuretic peptide (BNP), and cardiac output (CO). The results of the NMA indicated that Qili Qiangxin capsule (QLQX), Wenxin granule (WX), Tongxinluo capsule (TXL), Qishen Yiqi dropping pill (QSYQ), Shexiang Baoxin pill (SXBX), Yangxinshi tablet (YXST), Yixinshu capsule (YXSC), and Getong Tongluo capsule (GTTL) combined with CAM significantly improved performance compared with CAM alone in treating DCM-HF. YXST + CAM (MD = - 9.93, 95% CI - 12.83 to - 7.03) had the highest probability of being the best treatment on account of the enhancement of LVEF. WX + CAM had the highest likelihood of being the best treatment considering the improvement in LVEDD (MD = - 11.7, 95% CI - 15.70 to - 7.79) and 6MWT (MD = - 51.58, 95% CI - 73.40 to - 29.76). QLQX + CAM (MD = - 158.59, 95% CI - 267.70 to - 49.49) had the highest likelihood of being the best intervention for the reduction in BNP. TXL + CAM (MD = - 0.93, 95% CI - 1.46 to - 0.40) might be the optimal choice for increasing CO levels in DCM-HF patients. No serious treatment-emergent adverse events were observed. CONCLUSION This NMA suggested that adding CPMs to the current CAM treatment exerted a more positive effect on DCM-HF. Thereinto, QLQX + CAM, TXL + CAM, WX + CAM, and YXST + CAM showed a preferable improvement in patients with DCM-HF when unified considering the clinical effectiveness rate and other outcomes. Furthermore, due to the lack of information on CPMs against DCM-HF and the uneven distribution of included studies among interventions, more high-quality studies are needed to provide more robust evidence to support our findings.

Lyon exert anti-pulmonary fibrosis effect through targeting SETDB1/STAT3/p-STAT3 signaling. JOURNAL OF ETHNOPHARMACOLOGY 2023; 313:116520. [PMID: 37120058 DOI: 10.1016/j.jep.2023.116520] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 04/04/2023] [Accepted: 04/18/2023] [Indexed: 05/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pulmonary fibrosis (PF) is a pathological process of irreversible scarring of lung tissues, with limited treatment means. Sceptridium ternatum (Thunb.) Lyon (STE) is a traditional Chinese herbal medicine that has a traditional use in relieving cough and asthma, resolving phlegm, clearing heat, and detoxicating in China. However, its role in PF has not been reported. AIM OF THE STUDY This study aims to investigate the protective role of STE in PF and the underlying mechanisms. MATERIALS AND METHODS Sprague-Dawley (SD) rats were divided into control group, PF model group, positive drug (pirfenidone) group and STE group. After 28 days of STE administration in bleomycin (BLM)-induced PF rats, living Nuclear Magnetic Resonance Imaging (NMRI) was used to observe the structural changes of lung tissues. H&E and Masson's trichrome staining were used to observe PF-associated pathological alteration, and immunohistochemistry (IHC) staining, western blotting, and qRT-PCR were used to detect the expression of PF-related marker proteins in the lung tissues. ELISA was used to detect PF-associated biochemical criteria in the lung tissue homogenates. The proteomics technology was used to screen the different proteins. Co-immunoprecipitation, western blotting, and IHC staining were used to confirm the underlying targets of STE as well as its downstream signaling. UPLC-Triple-TOF/MS assay was used to explore the effective components in the alcohol extracts of STE. Autodock vina was used to detect the potential binding between the above effective components and SETDB1. RESULTS STE prevented PF by inhibiting the activation of lung fibroblasts and ECM deposition in BLM-induced PF rats. Mechanism analyses demonstrated that STE could inhibit the up-regulation of SETDB1 induced by BLM and TGF-β1, which further blocked the binding of SETDB1 and STAT3 as well as the phosphorylation of STAT3, ultimately preventing the activation and proliferation of lung fibroblasts. CONCLUSION STE played a preventive role in PF by targeting the SETBD1/STAT3/p-STAT3 pathway, which may be a potential therapeutic agent for PF.

[PMID: 36611616 PMCID: PMC9817788 DOI: 10.3390/ani13010005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 12/06/2022] [Accepted: 12/10/2022] [Indexed: 12/24/2022] Open
Abstract
Chinese herbal medicine plays an important role in regulating the nutritional metabolism of poultry and maintaining or improving normal physiological functions and animal health. The present study investigated the effects of dietary supplementation with Qiling Jiaogulan Powder (QLJP) on pulmonary fibrosis and pulmonary arteriole remodeling in low temperature-exposed broilers. Seven-day-old Ross 308 broilers (n = 240) were reared adaptively to 14 days of age. The broilers were randomly divided into six groups: A control group (basal diet and normal feeding temperature); model group (basal diet); low-, medium- and high-dose QLJP groups (basal diet supplemented with 1 g/kg, 2 g/kg, 4 g/kg QLJP); and L-Arg group (basal diet supplemented with 10 g/kg L-arginine). Additionally, all the broilers, except the broilers in the control group, from the age of 14 days old, had a house temperature continuously lowered by 2 °C each day until it reached 12 °C at 21 days of age, and the low temperature was maintained until the end of the experiment. There were four replicates per group and 10 birds per replicate. The results showed that the structure of the lung tissue was clearer and basically intact in the broilers in the QLJP groups, with a small number of collagen fibers formed, and the content of hydroxyproline (HYP) was significantly reduced. QLJP improved pulmonary arteriole lesions, such as tunica media thickening, intimal hyperplasia, arterial wall hypertrophy, and lumen narrowing. QLJP reduced the relative media thickness (%) and relative medial area (%) of the pulmonary arteriole, and significantly decreased the expression level of the alpha-smooth muscle actin (α-SMA) protein in pulmonary arteriole, which alleviated pulmonary arteriole remodeling. The quantitative real-time PCR (qPCR) and enzyme-linked immunosorbent assay (ELISA) results showed that QLJP treatment significantly reduced the gene and protein levels of transforming growth factor-beta l (TGF-β1) and Smad2 in the lung and downregulated the gene and protein levels of collagen type I alpha 1 (COL1A1) and matrix metalloproteinase 2 (MMP2). In conclusion, the results of our study suggested that dietary supplementation with QLJP improved pulmonary fibrosis and pulmonary arteriole remodeling by inhibiting the expression of genes related to the TGF-β1/Smad2 signaling pathway and inhibited the occurrence and development of pulmonary arterial hypertension in low-temperature-exposed broilers.

Vascular peroxidase 1 promotes phenotypic transformation of pulmonary artery smooth muscle cells via ERK pathway in hypoxia-induced pulmonary hypertensive rats. Life Sci 2022; 307:120910. [PMID: 36029851 DOI: 10.1016/j.lfs.2022.120910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Revised: 08/19/2022] [Accepted: 08/22/2022] [Indexed: 11/23/2022]
Abstract
AIMS Vascular peroxidase 1 (VPO1) plays an important role in mediation of vascular remodeling with pulmonary arterial hypertension (PAH). This study aims to determine whether VPO1 can promote phenotypic transformation of pulmonary artery smooth muscle cells (PASMCs) and the underlying mechanisms. MAIN METHODS Sprague-Dawley (SD) rats were exposed to 10 % O2 for 21 days to establish the model of vascular remodeling in pulmonary arterial hypertension. PASMCs were incubated with 3 % O2 for 48 h to induce phenotypic transformation. Western blot was performed to detect the expressions of target proteins. The 5-ethynyl-2'-deoxyuridine (EdU) assay was conducted to measure the proliferation of PASMCs. KEY FINDINGS In the rats exposed to hypoxia, there were increases in right ventricular systolic pressure, pulmonary vascular remodeling and phenotypic transformation of PASMCs (the down-regulated contractile proteins of α-smooth muscle actin, smooth muscle 22α while the up-regulated synthetic proteins of osteopontin, cyclinD1), accompanied by up-regulation of VPO1, increase of hypochlorous acid (HOCl) production and elevation of the phosphorylation of ERK. In the cultured PASMCs exposed to hypoxia, similar results were achieved but they were reversed by VPO1 small interfering RNA (VPO1 siRNA) or HOCl inhibitor. Replacement of hypoxia with NaOCl could induce PASMCs phenotypic transformation and activate the ERK signaling. Furthermore, ERK inhibitor (PD98059) could also attenuate hypoxia-induced PASMCs phenotypic transformation. SIGNIFICANCE VPO1 play a pivotal role in promotion of phenotypic transformation of PASMCs under hypoxic condition through activation of VPO1/HOCl/ERK pathway. It might serve as a potential target for prevention of pulmonary vascular remodeling.

Abstract
Pulmonary arterial hypertension (PAH) is characterized by pulmonary artery remodeling that may subsequently culminate in right heart failure and premature death. Although there are currently both non-pharmacological (lung transplantation, etc.) and pharmacological (Sildenafil, Bosentan, and new oral drugs on trial) therapies available, PAH remains a serious and fatal pulmonary disease. As a unique medical treatment, traditional herbal medicine (THM) treatment has gradually exerted its advantages in treating PAH worldwide through a multi-level and multi-target approach. Additionally, the potential mechanisms of THM were deciphered, including suppression of proliferation and apoptosis of pulmonary artery smooth muscle cells, controlling the processes of inflammation and oxidative stress, and regulating vasoconstriction and ion channels. In this review, the effects and mechanisms of the frequently studied compound THM, single herbal preparations, and multiple active components from THM are comprehensively summarized, as well as their related mechanisms on several classical preclinical PAH models. It is worth mentioning that sodium tanshinone IIA sulfonate sodium and tetramethylpyrazine are under clinical trials and are considered the most promoting medicines for PAH treatment. Last, reverse pharmacology, a strategy to discover THM or THM-derived components, has also been proposed here for PAH. This review discusses the current state of THM, their working mechanisms against PAH, and prospects of reverse pharmacology, which are expected to facilitate the natural anti-PAH medicine discovery and development and its bench-to-bedside transformation.

Protective effects of dioscin on vascular remodeling in pulmonary arterial hypertension via adjusting GRB2/ERK/PI3K-AKT signal. Biomed Pharmacother 2021; 133:111056. [PMID: 33378960 DOI: 10.1016/j.biopha.2020.111056] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 11/05/2020] [Accepted: 11/19/2020] [Indexed: 12/20/2022] Open
Abstract
Pulmonary arterial hypertension (PAH) is a progressive and lethal cardiopulmonary. Pulmonary vascular remodeling (PVR) caused by excessive proliferation and apoptosis resistance of pulmonary artery smooth muscle cells (PASMCs) is the chief pathological feature of PAH. Dioscin is a natural product that possesses multiple pharmacological activities, but its effect on PAH remains unclear. In this study, effect of dioscin on vascular remodeling in PAH was assessed in hypoxia-induced PASMCs, hypoxia-induced and monocrotaline (MCT)-induced rats. Western blot, Real-time PCR and siRNA transfection tests were applied to evaluate the possible mechanisms of dioscin. In vitro experiments, results showed dioscin markedly inhibited the proliferation and migration, and promoted apoptosis of hypoxic PASMCs. In vivo, dioscin significantly decreased the right ventricular systolic pressure (RVSP) and right ventricular hypertrophy index (RVHI), and improved pulmonary vascular stenosis in rats induced by hypoxia or MCT. Molecular mechanism studies showed that dioscin significantly reduced the expression of growth factor receptor-bound protein 2 (GRB2). Subsequently, dioscin reduced the expressions of Ras, Cyclin D1, CDK4, c-Fos, PCNA and p-ERK to inhibit proliferation and migration of PASMCs, inhibited p-PI3K and p-AKT levels and increased Bax/Bcl2 ratio to promote cell apoptosis. GRB2 siRNA transfection in PASMCs further confirmed that the inhibitory action of dioscin in PAH was evoked by adjusting GRB2/ERK/PI3K-AKT signal. Taken together, our study indicated that dioscin attenuates PAH through adjusting GRB2/ERK/PI3K-AKT signal to inhibit PASMCs proliferation and migration, and promote apoptosis, and dioscin may be developed as a therapeutic strategy for treating PAH in the future.

Abstract
OBJECTIVE To investigate the effect of early intervention of Tongxinluo (, TXL) on right ventricular function (RVF) of rats with pulmonary arterial hypertension (PAH) induced by monocrotaline (MCT). METHODS A total of 30 adult male Sprague-Dawley rats were assigned to 5 groups with complete random experiment design: Sham group (Sham), MCT group, TXL group, sildenafil (SIL) group and combination group (TXL+SIL), 6 rats in each group. Rats were injected with 50 mg/kg MCT solution for inducing PAH model except for those in the sham group. From the day of modeling, rats of TXL, SIL and TXL+SIL groups were given TXL (1.2 g/kg), SIL (10 mg/kg) and combination solution (TXL:1.2 g/kg, SIL: 10 mg/kg) respectively, and rats in Sham and MCT groups were given normal saline (5 mL/kg). The samples were collected and tested after 21 consecutive days of intragastric administration. Echocardiography was used to measure the related indices of RVF, including pulmonary arterial flow spectrum, pulmonary artery diameter (PAD), right ventricular wall thickness (RVWT), right ventricular diameter (RVD), tricuspidannular plane systolic excursion (TAPSE), right atrium transverse diameter (RAT), and inferior vena cava diameter (IVCD). Elastic Verhoeff-Van Gieson staining was adopted to measure the percentage of wall thickness (WT%) of pulmonary arteriols. Hematoxylin-eosin staining was used to measure the cross-sectional area (CSA) of right ventricular cardiomyocytes. RESULTS MCT-induced PAH rat model was successfully established. In MCT group the wall of pulmonary arterioles exhibited a prominent-increase thickness, PAD, RVWT, RVD, RAT, IVCD, WT%, right ventricular hypertrophy index (RVHI) as well as CSA of RV cardiomyocyte significantly increased (all P<0.01), and TAPSE markedly decreased (P<0.01). At the same time, TXL prominently improved all of the above indices (all P<0.01). In comparison with SIL, TXL significantly reduced RVD (P<0.05) and decreased CAS of RV cardiomyocytes (P<0.01), but TAPSE in SIL group was much larger than in TXL group (P<0.01). Moreover, TAPSE in TXL+SIL group was larger than that in TXL group (P<0.01), while the two groups performed equally well in terms of the other indices. CONCLUSION Early intervention of TXL could inhibit pulmonary arterioles remodeling, and improve RVF by attenuating right ventricular hypertrophy, and TXL has a stronger effect on inhibiting right ventricular remodeling than SIL.

Abstract
Background and Aims: Tongxinluo (TXL) is a multifunctional traditional Chinese medicine that has been widely used to treat cardiovascular and cerebrovascular diseases. However, no studies have explored whether TXL can protect human cardiomyocytes (HCMs) from ischemia/reperfusion (I/R) injury. Reperfusion Injury Salvage Kinase (RISK) pathway activation was previously demonstrated to protect the hearts against I/R injury and it is generally activated via Akt or (and) Erk 1/2, and their common downstream protein, ribosomal protein S6 kinase (p70s6k). In addition, prior studies proved that TXL treatment of cells promoted secretion of VEGF, which could be stimulated by the increased phosphorylation of one p70s6k subtype, p70s6k1. Consequently, we hypothesized TXL could protect HCMs from I/R injury by activating p70s6k1 and investigated the underlying mechanism. Methods and Results: HCMs were exposed to hypoxia (18 h) and reoxygenation (2 h) (H/R), with or without TXL pretreatment. H/R reduced mitochondrial membrane potential, increased bax/bcl-2 ratios and cytochrome C levels and induced HCM apoptosis. TXL preconditioning reversed these H/R-induced changes in a dose-dependent manner and was most effective at 400 μg/mL. The anti-apoptotic effect of TXL was abrogated by rapamycin, an inhibitor of p70s6k. However, inhibitors of Erk1/2 (U0126) or Akt (LY294002) failed to inhibit the protective effect of TXL. TXL increased p70s6k1 expression and, thus, enhanced its phosphorylation. Furthermore, transfection of cardiomyocytes with siRNA to p70s6k1 abolished the protective effects of TXL. Among the micro-RNAs (miR-145-5p, miR-128-3p and miR-497-5p) previously reported to target p70s6k1, TXL downregulated miR-128-3p in HCMs during H/R, but had no effects on miR-145-5p and miR-497-5p. An in vivo study confirmed the role of the p70s6k1 pathway in the infarct-sparing effect of TXL, demonstrating that TXL decreased miR-128-3p levels in the rat myocardium during I/R. Transfection of HCMs with a hsa-miR-128-3p mimic eliminated the protective effects of TXL. Conclusions: The miR-128-3p/p70s6k1 signaling pathway is involved in protection by TXL against HCM apoptosis during H/R. Overexpression of p70s6k1 is, therefore, a potential new strategy for alleviating myocardial reperfusion injury.
