[PMID: 40393254 DOI: 10.1016/j.atherosclerosis.2025.119226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2024] [Revised: 04/08/2025] [Accepted: 04/23/2025] [Indexed: 05/22/2025]
Abstract
BACKGROUND AND AIMS Atherosclerosis (AS) is a chronic inflammatory disease contributing to major cardiovascular events. This study aimed to investigate the effects of BAM15, a mitochondrial uncoupler, on regulating the NLRP3/ASC/caspase-1 signaling pathway to suppress endothelial cell pyroptosis and mitigate AS. METHODS AS was induced in ApoE-/- mice through a high-fat diet (HFD), and the therapeutic effects of BAM15 (5 mg/kg/day, s. c.) were evaluated. Histological analyses, including HE staining and oil red O staining, were used to assess aortic pathology and lipid deposition. Serum inflammatory cytokines (IL-1β, IL-18) were quantified by ELISA. Mouse primary aortic endothelial cells (MAECs) were treated with oxidized low-density lipoprotein (ox-LDL) to simulate AS condition in vitro. Mitochondrial reactive oxygen species (mtROS) expression and oxidized (ox)-mtDNA content were detected by Mitosox staining and ELISA, respectively. Western blot was used to assess the expression of pyroptosis-related proteins, including GSDMD-NT, NLRP3, ASC, and cleaved-caspase-1. RESULTS BAM15 reduced atherosclerotic plaque formation, lipid deposition, and inflammation, and diminished mtROS expression and ox-mtDNA content in the AS mouse models. In both in vivo and in vitro experiments, BAM15 markedly inhibited the activation of the NLRP3 inflammasome, leading to reduced pyroptosis in endothelial cells. Activation of the NLRP3/ASC/caspase-1 signaling pathway by Nigericin partially reversed the protective effects of BAM15, underscoring the pivotal role of NLRP3 inflammasome inhibition in endothelial pyroptosis suppression. CONCLUSIONS BAM15 effectively inhibits endothelial cell pyroptosis by reducing mtROS production and ox-mtDNA release to suppress the NLRP3/ASC/caspase-1 signaling pathway, thereby alleviating AS in both in vivo and in vitro models.

Mol Med Rep 2025; 32:186. [PMID: 40314092 PMCID: PMC12076288 DOI: 10.3892/mmr.2025.13551] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2024] [Accepted: 03/12/2025] [Indexed: 05/03/2025] Open
Abstract
Atherosclerosis (AS)‑related coronary artery disease is the main cause of morbidity and mortality around the globe. Eburicoic acid, a triterpenoid compound from Antrodia camphorata, exerts anti‑inflammatory and anti‑hyperlipidemic effects, although its role in atherogenesis remains unknown. Endothelial cell pyroptosis‑caused chronic inflammatory response within vessel walls is a critical initial event in atherogenesis, making it a promising target to prevent AS. The present study was designed to investigate the effects of eburicoic acid on endothelial cell pyroptosis, AS progression and the underlying mechanisms. The results showed that with dose and time increased, treatment of human umbilical vascular endothelial cells (HUVECs) with eburicoic acid markedly decreased the expression of Kelch‑like ECH‑associated protein 1 (Keap1), NF‑E2‑related factor 2 (Nrf2), reactive oxygen species (ROS), NLR family pyrin domain‑containing protein 3 (NLRP3), cleaved caspase‑1, apoptosis‑associated speck‑like protein containing CARD (ASC), N‑terminal gasdermin‑D (GSDMD‑N), downregulated the secretion levels of pro‑inflammatory cytokines interleukin (IL) 1β, IL‑6 and IL‑18, inhibited caspase‑1 activity and lactate dehydrogenase release and improved plasma membrane integrity. By contrast, the expression of nuclear Nrf2, total Nrf2 and heme oxygenase‑1 (HO‑1) were increased by eburicoic acid treatment in HUVECs dose‑ and time‑dependently. Moreover, the inhibitory effects of eburicoic acid on HUVEC pyroptosis were mainly compromised by pre‑treatment with ROS agonist, HO‑1 small interfering (si)RNA, or Nrf2 siRNA. Finally, it was observed that administering high‑fat‑diet fed ApoE‑/‑ mice with eburicoic acid markedly increased Nrf2 and HO‑1 levels and reduced the expression of Keap1, NLRP3, cleaved caspase‑1, ASC and GSDMD‑N in aortas and ameliorated hyperlipidemia and inflammation in the serum, leading to smaller atherosclerotic plaques, less lipid accumulation and high content of collagen fiber within plaques. These findings identified eburicoic acid as a potent anti‑atherogenic natural product by suppressing endothelial cell pyroptosis via the Keap1/Nrf2/HO‑1/ROS pathway. Eburicoic acid may be considered an effective phytomedicine for treating AS.

Sinomenine ameliorates vascular calcification by inhibiting pyroptosis-related molecules and AEG-1 in chronic kidney disease. Eur J Pharmacol 2025; 996:177594. [PMID: 40187593 DOI: 10.1016/j.ejphar.2025.177594] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2024] [Revised: 03/27/2025] [Accepted: 04/02/2025] [Indexed: 04/07/2025]
Abstract
BACKGROUNDS Vascular calcification (VC) is an important factor for mortality in chronic kidney disease (CKD). Sinomenine can suppress atherosclerosis. However, its role in CKD-associated-vascular calcification and mechanisms remain unclear. METHODS Sprague-Dawley rats that were fed with high-phosphorus diet and adenine suspension were used to construct the calcification model in CKD. Calcification from rats or cells were analyzed using micro-CT and alizarin red staining. Levels of NLRP-3, Caspase-1, GSDMD and AEG-1 were measured by qPCR, western blotting, and immunohistochemistry. Transfection experiment was used in function study. RESULTS CKD rats fed with high-phosphorus diet and adenine suspension increased aortic calcification over time. Micro-CT images revealed the distribution and severity of the calcification, and these lesions were significantly decreased in the Sinomenine (SIN) group. This is similar to the results obtained for the AR staining of translucent samples. Additionally, aortas from CKD rats that were treated with 30 mg/kg/d SIN showed a down-regulation of NLRP3, Caspase-1, GSDMD and AEG-1 expression compared with aortas from CKD rats. Sinomenine exhibited similar inhibitory effects on NLRP3 and Caspase-1 as VX-765 in the aortas of uremic rats and calcified VSMCs. Moreover, VSMC transfected with pc-AEG-1 accelerated the VSMC calcification while transfection with si-AEG-1 ameliorated the calcification. Importantly, sinomenine abolished the VSMC calcification induced by AEG-1 overexpression under the uremia condition. CONCLUSIONS Our findings indicated that sinomenine could ameliorate vascular calcification in CKD rats and inhibit hyperphosphatemia-induced calcifying VSMCs via inhibiting pyroptosis-related molecules and AEG-1. Sinomenine might serve as an effective therapeutic agent for CKD-associated vascular calcification.

Guo J, Sun J, Xiong M, Wang L, Han N, Wang T, He Z, Yuan C, Ma Y, Qi H, Hou Y, Jia Z. Pulmonary microvascular endothelial glycocalyx degradation as a key driver in COPD progression and its protection by Tongxinluo. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2025; 143:156878. [PMID: 40424984 DOI: 10.1016/j.phymed.2025.156878] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/21/2025] [Revised: 05/15/2025] [Accepted: 05/18/2025] [Indexed: 05/29/2025]
Abstract
BACKGROUND Chronic Obstructive Pulmonary Disease (COPD) is a major cause of morbidity and mortality worldwide. Pulmonary microvascular endothelial glycocalyx (PMEG) has been found to be significantly reduced in COPD, but the mechanism, cause, and effect of the reduction on COPD progression are inconclusive. OBJECTIVE This study aims to explore the mechanisms and consequences underlying PMEG degradation in COPD. Additionally, we strive to ascertain whether Tongxinluo (TXL)'s protective role in COPD is mediated through the preservation of PMEG integrity. METHODS A staged cigarette smoke (CS) exposure model was employed to investigate the timeline, trajectory, mechanisms, and causes of glycocalyx degradation, with in vitro validation. The in vivo glycocalyx degradation model was induced by intravenous injection of glycocalyx hydrolase along with CS exposure. The protective effect of TXL on glycocalyx integrity was examined in CS-exposed mice treated with TXL. RESULTS PMEG degradation occurs as early as 2 weeks after CS exposure and worsens as the disease advances. Multiple glycocalyx degrading enzyme upregulation at different time points collectively results in consistent glycocalyx component degradation. Mechanistically, CS or reactive oxygen species (ROS) exposure elevates pro-inflammatory cytokine secretion, leading to an increase in glycocalyx hydrolysis expression and subsequent PMEG degradation on the endothelial cell (EC) surface. PMEG degradation further promotes inflammatory cell infiltration and accelerates endothelial apoptosis, ultimately driving disease progression in COPD. TXL alleviates oxidative stress, reverses the upregulation of PMEG degrading enzyme, preserves PMEG integrity, reduces endothelial cell apoptosis, and mitigates COPD pathology. CONCLUSION In summary, this study provides groundbreaking insights into the role of PMEG degradation in COPD pathogenesis and introduces TXL as a novel therapeutic agent with the potential to preserve PMEG integrity and mitigate COPD progression. These findings significantly advance our understanding of COPD and offer innovative directions for future research and therapeutic development.

Abstract
Atherosclerosis (AS) is a chronic inflammatory disease characterized by the gradual accumulation of plaques in arterial walls, with its pathogenesis remaining incompletely understood. Recent studies have highlighted that development of AS is closely associated with the aberrant activation of the NLRP3 inflammasome in the arteries. Inhibition of the NLRP3 inflammasome by natural products and formulae derived from Chinese herbal medicines (CHMs) has been shown to alleviate AS-associated pathologies. However, therapies that effectively and safely target the NLRP3 inflammasome remain limited. This review aims to summarize the key discoveries from recent studies on the effects of these natural products and formulae on the NLRP3 inflammasome in the context of AS treatment. A comprehensive literature search was conducted on databases such as PubMed/MEDLINE up to January 2025, yielding 38 eligible studies. Our analysis indicates that certain therapies can effectively prevent arterial inflammation in animal models by targeting multiple pathways and mechanisms related to the NLRP3 inflammasome. This review summarizes the primary findings of these studies, focusing on the therapeutic effects and underlying mechanisms of action. Based on these insights, we propose future strategies to enhance the efficacy, specificity, and safety of existing natural products and formulae for AS treatment. Additionally, this study offers a perspective for future research that may enhance our understanding of the roles and the mechanisms of CHM-derived phytochemicals and formulae in regulating the NLRP3 inflammasome and treating AS.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese Medicine (TCM) shows growing potential as an adjunct or alternative therapy for vascular occlusion diseases (e.g., stroke, peripheral artery disease) by promoting therapeutic angiogenesis to restore blood flow in ischemic regions while minimizing side effects. AIMS OF THE STUDY This review examines TCM-mediated angiogenesis mechanisms and therapeutic advances in vascular occlusion management, establishing a theoretical foundation for clinical translation and precision medicine development. MATERIALS AND METHODS We systematically analyzed PubMed articles on TCM-induced angiogenesis in vascular occlusion diseases, focusing on herbal formulations, single herbs, bioactive compounds, and their associated signaling pathways. Search PubMed for studies investigating the role of Chinese herbal medicine (TCM), natural compounds, and herbal medicine in angiogenesis, while excluding research related to cancer, tumor, or oncological contexts. RESULTS TCM formulas, individual herbs, and monomeric compounds enhance endothelial cell proliferation, migration, and tube formation via pathways such as HIF/VEGF, PI3K/AKT, NOTCH, BMP/ALK, and Apelin/APJ, improving ischemic blood flow. CONCLUSION This review highlights angiogenesis as a novel strategy for vascular occlusive diseases and underscores TCM's efficacy through multi-target angiogenic regulation mechanism.However, further research using modern medical technologies is needed to optimize clinical application and advance precision medicine.

Efficacy and safety of Tongxinluo capsules combined with conventional therapy for acute myocardial infarction: a systematic review and meta-analysis. Front Pharmacol 2025; 16:1555859. [PMID: 40337524 PMCID: PMC12055842 DOI: 10.3389/fphar.2025.1555859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2025] [Accepted: 03/25/2025] [Indexed: 05/09/2025] Open
Abstract
Background Tongxinluo capsule, a formally classical commercial Chinese polyherbal preparation, has been utilized to treat patients with acute myocardial infarction for decades. Purpose This meta-analysis aimed to comprehensively evaluate the clinical outcomes of tongxinluo capsule treated acute myocardial infarction. Methods Randomized controlled trials evaluating the effectiveness of tongxinluo capsule alone or in combination with conventional therapy in patients with acute myocardial infarction were identified from eight major databases: Chinese Biomedical Medicine, China National Knowledge Infrastructure, Wanfang Med Database, China Science and Technology Journal Database, PubMed, and Cochrane Central Register of Controlled Trials. In addition, two clinical trial registry platforms (clinicalTrials.gov and the WHO International Clinical Trials) were also searched for relevant studies, with the search extending to all published literature until December 2024. The initial screening and evaluation of the studies were carried out by two independent reviewers who assessed each study according to predefined eligibility criteria. The risk of bias in the research was evaluated using the Cochrane Collaboration's methodology for assessing methodology. Meta-analysis was carried out using RevMan 5.3 software, and publication bias was assessed utilizing StataMP 14.0. The evidence's quality was determined by the Grading of Recommendations Assessment, Development, and Evaluation process. Results This research included a total of 36 randomized controlled trials with 7002 patients. The meta-analysis revealed that Tongxinluo capsule combined with conventional treatment significantly decreased the 1-month MACCE rate (RR = 0.62, 95% CI 0.47 to 0.81; p = 0.0007), along with the individual risks of 1-month MACCE, including cardiac death (RR = 0.68, 95% CI 0.50 to 0.93; p = 0.02) and myocardial reinfarction (RR = 0.11, 95% CI 0.01 to 0.94; p = 0.04). After 12 months of treatment, the MACCE rate (RR = 0.61, 95% CI 0.49 to 0.75; p < 0.00001), cardiac death (RR = 0.69, 95% CI 0.50 to 0.96; p = 0.03), myocardial reinfarction (RR = 0.32, 95% CI 0.13 to 0.75; p = 0.009), and stroke (RR = 0.42, 95% CI 0.20 to 0.87; p = 0.02) were also reduced. The remaining secondary outcomes-1-month stroke (RR = 0.44, 95% CI 0.44 to 1.44; p = 0.18), 12-month (RR = 0.12, 95% CI 0.01 to 2.14; p = 0.15) emergent coronary revascularization, 12-month all-cause mortality (RR = 0.78, 95% CI 0.60 to 1.01; p = 0.06)-showed no differences. Furthermore, the combination of Tongxinluo capsule and conventional therapy increased the incidence of the adverse drug reaction, mainly gastrointestinal discomfort (RR = 1.80, 95% CI 1.14 to 2.84; p = 0.01). However, there were no differences in the liver function levels of aspartate transaminase (SMD = -0.24, 95% CI -0.54 to -0.07; p = 0.12) and alanine aminotransferase (SMD = -0.25, 95% CI -0.55 to 0.05; p = 0.11), or the kidney function levels of blood urea nitrogen (SMD = 0.32, 95% CI -0.21 to 0.86; p = 0.23) and creatinine (SMD = 0.10, 95% CI -0.20 to 0.40; p = 0.52). Conclusion Current data indicates that Tongxinluo capsule, used as an adjuvant treatment, may enhance clinical outcomes for AMI patients at 1- and 12-month. Moreover, it may enhance heart function, regulate lipid peroxidation, and suppress inflammatory levels.

Abstract
Targeted regulation of pyroptosis to modulate the immune landscape has emerged as a novel design strategy for cancer immunotherapy and anti-inflammatory therapy. However, pyroptosis acts as a double-edged sword, making it important to optimize the design strategies of functional materials to appropriately activate pyroptosis for effective disease treatment. This paper summarizes and discusses the structure, pore formation, and molecular mechanisms of "executor" Gasdermins, as well as the events preceding and following these processes. Subsequently, the focus is on reviewing functional materials that directly regulate Gasdermin pore formation to target pyroptosis and those that indirectly regulate the events before and after Gasdermin pore formation to control pyroptosis activity. Finally, the advantages, disadvantages, and future prospects of designing such functional materials are provided, aiming to facilitate the precise design, pharmacological investigation, and clinical translation of pyroptosis-related functional materials.

Abstract
Atherosclerosis (AS) is a chronic vascular disease primarily affecting large and medium-sized arteries, involving complex pathological mechanisms such as inflammatory responses, lipid metabolism disorders and vascular plaque formation. In recent years, several emerging research hotspots have appeared in the field of atherosclerosis, including gut microbiota, pyroptosis, ferroptosis, autophagy, cuproptosis, exosomes and non-coding RNA. Traditional lipid-lowering drugs play a crucial role in the treatment of AS but are not able to significantly reverse the pathological changes. This article aims to summarize the latest research progress in the pathogenesis of AS and the diagnosis and treatment of the disease by comprehensively analyzing relevant literature mainly from the past five years. Additionally, the mechanisms of action and research advances of statins, cholesterol absorption inhibitors, fibrates and novel lipid-lowering drugs are reviewed to provide new insights into the diagnosis and treatment of AS.

Abstract
Ischemic cardiomyopathy (ICM) is a special type or end stage of coronary heart disease or other irreversible ischemic myocardial injury. Inflammatory damage to coronary vessels is a crucial factor in causing stenosis or occlusion of coronary arteries, resulting in myocardial ischemia and hypoxia, but it is also an aspect of cardioprotection that is often overlooked. This review discusses the mechanisms of vascular injury during ICM, in which inflammation and oxidative stress interact and trigger cell death as the cause of coronary microvascular injury. Imbalances in endoplasmic reticulum function and mitochondrial quality control are important potential drivers of inflammation and oxidative stress. In addition, many studies have confirmed the therapeutic effects of Chinese herbal medicines and their natural monomeric components on vascular injuries. Their mitochondrial quality control and endoplasmic reticulum protection mechanisms as well as their role in combating improvements in vascular endothelial function and attenuating vascular injury are also summarized, with a perspective to provide a reference for pathologic understanding, drug research, and clinical application of ICM-associated coronary microvascular injury.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tongxinluo (TXL), a Chinese patent medicine, is commonly used for secondary prevention of cardiovascular events. AIM OF THE STUDY To evaluate the efficacy and safety of TXL for secondary prevention after ST-segment elevation myocardial infarction (STEMI). MATERIALS AND METHODS A search for relevant randomized controlled trials (RCTs) was conducted across seven electronic databases from inception to May 10, 2024. Two independent reviewers conducted trial selection, data collection, and bias assessment. We performed a meta-analysis of efficacy and safety outcomes, and assessed the quality of evidence. RESULTS Ten RCTs were included, involving 4690 patients with STEMI. Compared to conventional treatments (CTs) alone, TXL combined with CTs reduced the incidence of major adverse cardiac and cerebrovascular events (MACCEs) in patients with STEMI (risk ratio [RR] = 0.61, 95 % confidence interval [CI] 0.51 to 0.73, P < 0.00001). TXL also contributed to improving cardiac function (mean difference [MD] = 4.95, 95 % CI 3.26 to 6.64, P < 0.00001). Furthermore, no statistically significant difference was observed in the incidence of adverse events between the TXL and control groups. The certainty of evidence was evaluated as moderate to low. CONCLUSION TXL might provide preventive effects against MACCEs for patients with STEMI. However, the efficacy and safety of TXL for secondary prevention in real-world settings require further confirmation through future practice.

Abstract
Introduction In plaque sites of atherosclerosis (AS), the physiological barrier caused by the thick fiber cap due to the overmigration of vascular smooth muscle cells (VSMCs) prevents efficient drug delivery to damaged macrophages. How to ensure precise targeted delivery of drugs to plaque sites and their on-demand release to dysfunctional cells under the thick fibrous cap are feasible solutions to enhance AS treatment. Methods A small complex of methotrexate (MTX)-human serum albumin (HSA) with strong, thick fibrous cap penetration ability was encapsulated in a cholesterol hemisuccinate (CHEM) prepared pH-sensitive liposome, modifying with ROS-responsive PEG2000-TK-DSPE (PTD), termed PTD/Lipo/MTX-HSA. Results PTD/Lipo/MTX-HSA can achieve precise targeting and on-demand release in response to plaques environments of AS. The designed formulation accelerated the release of the small-sized MTX-HSA complex in response to excess ROS and acidic pH conditions, and it better penetrated the macrophage spheroids. Furthermore, it has precise targeting ability in the AS mouse model and can produce good anti-inflammatory efficacy by inhibiting p65 entry into the nucleus turn out inflammatory factor. Conclusion Our formulations work with safety in mind, and it also highlights the potential of precisely targeted and on-demand-released dual-responsive smart nanoplatforms as promising therapeutic options to penetrate deeper plaques for the effective treatment of AS.

Abstract
Background Chronic coronary syndromes (CCS) is a common clinical condition that increases the risk of cardiovascular events at any time. Tongxinluo capsules (TXL) are widely used in China for treating CCS. Objectives To systematically evaluate the therapeutic effects and safety of adding TXL to Western medical treatment (WM) for CCS. Methods We searched PubMed, Cochrane Library, CNKI, VIP, and Wanfang databases up to August 2024 for randomized controlled trials (RCTs) investigating the therapeutic effects and safety of combining TXL with WM compared to WM alone for CCS. Data analyses were conducted using RevMan 5.4 software. Results Twenty studies involving 2091 participants were identified. Evidence supports the use of TXL plus WM for reducing angina frequency [SMD -2.50, 95% CI (-3.53, -1.48)], improving seattle angina questionnaire scores (P < 0.05), decreasing nitroglycerin dose [SMD -1.63, 95% CI (-2.26, -1.00)], and shortening angina duration [MD -1.50 min/once, 95% CI (-1.98, -1.02)]. Adding TXL to WM showed a non-significant trend toward reducing myocardial infarction [RR 0.34, 95% CI (0.05, 2.12); NNT = 41] and sudden cardiac death [RR 0.34, 95% CI (0.01, 8.28); NNT = 65]. No increase in adverse events was observed when TXL was added to WM [RR 1.02, 95% CI (0.70, 1.49); NNT = 149]. Conclusions Our review suggests that TXL may offer additional therapeutic benefits for CCS patients and appears to be safe when combined with WM. Further investigations are warranted to confirm the potential impact of adding TXL to WM for CCS.

Phytother Res 2024; 38:5458-5473.

Abstract
Natural antioxidants have been shown to be effective against atherosclerosis. Ginkgo flavone aglycone (GA) has strong antioxidant properties and can protect against endothelial damage. However, the mechanisms by which GA protects against atherosclerosis remain largely unexplored. This study hopes to find the anti-atherosclerotic mechanism of GA. ApoE-/- mice fed a high-fat diet were used for modeling atherosclerosis. The efficacy of GA on mice with atherosclerosis was evaluated based on the following indicators: Oil Red O staining, Masson staining, lipid content, and apoptosis. Transmission electron microscopy, Western blot, immunofluorescence staining, and propidium iodide staining were used to analyze the effects of GA on ox-LDL-treated human aortic endothelial cells. GA activated Nrf2 by promoting the nuclear translocation of Nrf2, thereby inhibiting endothelial pyroptosis. GA prevented endothelial pyroptosis suppressed oxidative stress, and inhibited the development of atherosclerosis in ApoE-/- mice fed high-fat diets. At the cellular level, GA suppressed ox-LDL-induced pyroptosis of HAECs by reducing reactive oxygen species (ROS) levels and inhibiting NLRP3 inflammasome. Furthermore, siRNA targeting Nrf2 or ML385, an Nrf2 inhibitor, reversed these effects. GA liberated Nrf2 from Keap1 sequestration, enhanced the nuclear translocation of Nrf2 and the transcription of downstream antioxidant proteins, reinforced the antioxidant defense system, and inhibited oxidative stress, thereby preventing endothelial cell pyroptosis, and attenuating the progression of atherosclerosis. This study indicated that GA mitigated endothelial pyroptosis by modulating Keap1/Nrf2 interactions, shedding light on the potential mechanisms underlying the protective effects of natural antioxidants against atherosclerosis.

Abstract
BACKGROUND Cardiovascular and cerebrovascular disease (CCVD) is the leading cause of morbidity and mortality worldwide, imposing a significant economic burden on individuals and societies. For the past few years, Traditional Chinese Medicine (TCM) has attracted much attention due to its advantages such as fewer side effects in the treatment of CCVD. TXL has shown great promise in the treatment of CCVD. PURPOSE This paper aims to provide a comprehensive introduction to TXL, covering its chemical constituents, quality control, pharmacological properties, adverse reactions, and clinical applications through an extensive search of relevant electronic databases while discussing its current challenges and provides opinions for future study. METHODS The following electronic databases were searched up to 2023: "TXL", "CCVD", "Chemical constituents", "Quality control" and "Pharmacological properties" were entered as keywords in PubMed, Web of Science, Google Scholar and China National Knowledge Infrastructure Database and WANFANG DATA databases. The PRISMA guidelines were followed in this review process. RESULTS Studies have confirmed that TXL is effective in treating patients with CCVD and has fewer adverse effects. The aim of this review is to explore TXL anti-CCVD effects in relation to oxidative stress, lipid metabolism and enhanced cardiac function. This review also provides additional information on safety issues. CONCLUSION TXL plays a key role in the treatment of CCVD by regulating various pathways such as lipid metabolism, oxidative stress and inflammation. However, further clinical trials and animal experiments are needed to provide more evidence and recommendations for its clinical application. This article provides an overview of TXL research to inform and inspire future studies.

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.

Electroacupuncture improves low-grade duodenal inflammation in FD rats by reshaping intestinal flora through the NF-κB p65/NLRP3 pyroptosis pathway. Heliyon 2024; 10:e31197. [PMID: 38807876 PMCID: PMC11131961 DOI: 10.1016/j.heliyon.2024.e31197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Revised: 05/11/2024] [Accepted: 05/13/2024] [Indexed: 05/30/2024] Open
Abstract
Electroacupuncture (EA) is an effective alternative for the treatment of functional dyspepsia (FD). It reduces low-grade duodenal inflammation and improves the symptoms of FD by downregulating the expression of NF-κB p65 and NLRP3, but its mechanism needs to be elucidated. To examine the regulatory effect of electroacupuncture (EA) on intestinal flora and NF-κB p65/NLRP3 pyroptosis pathway in FD rats. The FD rat model was established via multi-factor stress intervention for two weeks. The rats were randomly divided into the NC group, model group, NF-kB inhibitor group (NF-κB inhibitor BAY 11-7082 was administered), EA group, and EA + NF-kB inhibitor group. After 14 days of treatment, the rats were sacrificed, and the protein and mRNA levels of NF-κB p65, IκB, and NLRP3 in the duodenum were evaluated by Western blotting assays and real-time fluorescent quantitative PCR. The Illumina MiSeq sequencing platform was used to analyze the V4 region of the 16S rRNA gene of intestinal flora and predict functional genes. The concentration of short-chain fatty acids (SCFAs) in feces was assessed by metabolomics. EA can decrease low-grade duodenal inflammation and promote gastrointestinal motility in FD rats. This effect is mediated by inhibition of the NF-κB p65/NLRP3 pyroptosis pathway, an increase in the alpha and beta diversity of gut microbiota in the duodenum, an increase in the abundance of beneficial bacteria at the phylum and genus levels, and an increase in the content of SCFAs. The protective effect of EA against FD might involve multiple hierarchy and pathways. EA may remodel intestinal flora by inhibiting the NF-κB p65/NLRP3 pyroptosis pathway, thereby improving low-grade duodenal inflammation in FD rats.

Abstract
INTRODUCTION Fisetin has been demonstrated to inhibit the occurrence of atherosclerosis; however, the mechanism of fisetin suppressing atherosclerosis remains elusive. METHODS The function of fisetin in the inhibition of atherosclerosis was evaluated by hematoxylin and eosin and Oil Red O staining in ApoE-/- mice. Molecular biomarkers of atherosclerosis progression were detected by Western blot and qPCR. Moreover, the inhibition of atherosclerosis on oxidative stress and ferroptosis was evaluated by immunofluorescence staining, qPCR, and Western blot assays. RESULTS The obtained results showed that serum lipid was attenuated and consequentially the formation of atherosclerosis was also suppressed by fisetin in ApoE-/- mice. Exploration of the mechanism revealed that molecular biomarkers of atherosclerosis were decreased under fisetin treatment. The level of reactive oxygen species and malondialdehyde declined, while the activity of superoxide dismutases and glutathione peroxidase was increased under the fisetin treatment. Additionally, the suppressor of ferroptosis, glutathione peroxidase 4 proteins, was elevated. The ferritin was decreased in the aortic tissues treated with fisetin. CONCLUSIONS In summary, fisetin attenuated the formation of atherosclerosis through the inhibition of oxidative stress and ferroptosis in the aortic tissues of ApoE-/- mice.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 919:170699. [PMID: 38325474 DOI: 10.1016/j.scitotenv.2024.170699] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 02/02/2024] [Accepted: 02/03/2024] [Indexed: 02/09/2024]
Abstract
During feeding process in intensive chicken farms, the prolonged exposure of chickens to elevated level of ammonia leads to substantial economic losses within poultry farming industry. Luteolin (Lut), known as its anti-inflammatory and antioxidant properties, possesses the ability to eliminate free radicals and enhance the activities of antioxidant enzymes, thus rendering it highly esteemed in production. The objective of this study was to examine the effects of Lut on antioxidant and anti-inflammatory responses of chicken splenic lymphocytes exposed to ammonia. In order to achieve this, we have replicated a protective model involving Lut against ammonia exposure in chicken splenic lymphocytes. The findings of the study indicated that Lut mitigated the elevation of lactate dehydrogenase (LDH), malondialdehyde (MDA), and reactive oxygen species (ROS) induced by ammonia poisoning. Additionally, Lut demonstrated an increase in the expression of antioxidant enzymes, namely superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Furthermore, Lut exhibited a protective effect on cell morphology and ultrastructure following exposure to ammonia. Moreover, Lut exhibited a reduction in the expression of heat shock proteins (HSPs) and inflammatory cytokines, which were found to be highly expressed in splenic lymphocytes after ammonia exposure. Additionally, Lut demonstrated the ability to inhibit the overexpression of pyroptosis-related genes and proteins (NLRP3 and Caspase-1) in splenic lymphocytes following ammonia exposure. Lut exerted an antioxidant effect on lymphocytes, counteracting elevated levels of oxidative stress following exposure to ammonia. Additionally, Lut had the potential to modulate the expression of HSPs, suppressed the inflammatory response subsequent to ammonia exposure, and influenced the expression of NLRP3 and Caspase-1, thereby mitigating pyroptosis induced by ammonia exposure. The exploration of this subject matter can elucidate the protective properties of Lut against NH4Cl-induced damage in chicken splenic lymphocytes, while also offer insights and experimental groundwork for the utilization of natural therapeutics in animal husbandry to prevent and treat ammonia-related conditions.

Efficacy and safety of tongxinluo capsule for angina pectoris of coronary heart disease: an overview of systematic reviews and meta-analysis. Front Cardiovasc Med 2024; 11:1229299. [PMID: 38414926 PMCID: PMC10896841 DOI: 10.3389/fcvm.2024.1229299] [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: 06/01/2023] [Accepted: 01/17/2024] [Indexed: 02/29/2024] Open
Abstract
Background Tongxinluo capsule (TXLC) is a common drug for treating angina pectoris of coronary heart disease (CHD). In recent years, many systematic reviews (SRs) and meta-analyses (MAs) have reported the efficacy and safety of TXLC for improving angina symptoms in patients with CHD. We aimed to comprehensively evaluate the existing SRs and MAs of TXLC in treating angina pectoris of CHD, summarize the evidence quality, and provide scientific evidence and recommendations. Methods We searched seven databases for relevant SRs/MAs published up to 1 June 2023. Two reviewers independently completed the literature retrieval, screening, and data extraction. We used A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2) to evaluate the methodological quality, the Risk of Bias in Systematic Reviews (ROBIS) to assess the risk of bias, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) to determine the strength of the evidence. RevMan 5.3 was used to synthesize data. Results We identified 15 SRs/MAs, including 329 RCTs and 33,417 patients. According to the evaluation results of AMSTAR-2, only one SR was of high methodological quality, the others were very low. ROBIS assessment showed that one SR (6.67%) had a low risk, 3 SRs (20%) had an unclear risk, and 11 SRs (73.33%) had a high risk. We assessed 42 outcomes by the GRADE, 10 (23.81%) for moderate-quality evidence, 17 (40.48%) for low-quality evidence, and 15 (35.71%) for very-low-quality evidence. Mate-analysis showed that TXLC combined with conventional western medications improved electrocardiogram efficacy (RR = 1.38, 95% CI: 1.23-1.43, P < 0.001) and angina efficacy (OR = 3.58, 95% CI: 3.02-4.24, P < 0.001), reduced angina attack frequency (SMD = -0.54, 95% CI: -0.64 to -0.44, P < 0.001) and angina duration (SMD = -0.42, 95% CI: -0.57 to -0.28, P < 0.001), with general heterogeneity. The pooled results showed that TXLC appears to have some efficacy in improving cardiac function and relieving angina symptoms, but there is limited evidence that it improves cardiovascular event rates, hemorheology, lipids, or hs-CRP. In the assessment of drug safety, TXLC was associated with different degrees of adverse drug reactions. Conclusion Based on the evidence, TXLC may be effective as an adjuvant treatment for angina pectoris of CHD. However, the quality of the evidence is low, and the drug's safety must be carefully interpreted. In future studies, high-quality randomized controlled trials are needed to confirm the effectiveness and safety of TXLC.
