PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 130:155719. [PMID: 38763013 DOI: 10.1016/j.phymed.2024.155719] [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: 01/20/2024] [Revised: 04/29/2024] [Accepted: 05/05/2024] [Indexed: 05/21/2024]
Abstract
BACKGROUND Myocardial fibrosis is a risk factor that contributes to the increase in the incidence of cardiovascular disease and death, posing a significant threat to human health. Zhen-wu-tang (ZWT) is a classical Chinese medicinal recipe that has been extensively used to manage cardiovascular disorders throughout history. However, the fundamental processes involved in its effects were not clear. OBJECTIVE This study examined the therapeutic effects of ZWT on myocardial fibrosis induced by isoproterenol (ISO) in mice, the effect of regulation and underlying mechanism on the polarization of M1 macrophage. METHODS In vivo, a myocardial fibrosis mouse model was induced via intraperitoneal infusion of isoproterenol (ISO). ZWT or captopril (CAP) was administered intragastrically for 30 days. Cardiac function was evaluated by electrocardiogram (ECG) and echocardiography. By analysing myocardial fibrosis pathomorphologically and identifying fibrosis-related indicators, the protective effect of the ZWT on the heart was evaluated. A model of macrophage polarization was established in vitro by activating RAW264.7 cells with lipopolysaccharide (LPS). The regulatory effects of ZWT on macrophage polarization and the signalling pathways involved were examined by immunofluorescence staining, Western blotting (WB), quantitative real-time PCR (qRT-PCR) and siRNA transfection. RESULTS ZWT improved cardiac function; reduced fibrotic deposition in cardiac tissues; decreased α-SMA, collagen I, and collagen III levels; and inhibited myocardial fibrosis in mice with ISO-induced myocardial fibrosis. Furthermore, the results showed that ZWT could suppress M1 macrophage polarization by downregulating the expression of CD86 and iNOS in vitro and in vivo. Finally, the results confirmed that ZWT could significantly reduce TLR4/NF-κB signalling pathway activation. CONCLUSION ZWT showed therapeutic effects on ISO-induced myocardial fibrosis mice, and reduced M1 macrophages polarization through inhibiting TLR4/NF-κB pathway, suggesting that ZWT is a promising drug for myocardial fibrosis treatment.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 329:118144. [PMID: 38583732 DOI: 10.1016/j.jep.2024.118144] [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: 01/03/2024] [Revised: 03/19/2024] [Accepted: 04/01/2024] [Indexed: 04/09/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gynecological disorders have the characteristics of high incidence and recurrence rate, which sorely affects female's health. Since ancient times, traditional Chinese medicine (TCM), especially tonic medicine (TM), has been used to deal with gynecological disorders and has unique advantages in effectiveness and safety. AIM OF THE REVIEW In this article, we aim to summarize the research progress of TMs in-vivo and in-vitro, including their formulas, single herbs, and compounds, for gynecological disorders treatment in recent years, and to offer a reference for further research on the treatment of gynecological disorders and their clinical application in the treatment of TMs. MATERIALS AND METHODS Relevant information on the therapeutic potential of TMs against gynecological disorders was collected from several scientific databases including Web of Science, PubMed, CNKI, Google Scholar and other literature sources. RESULTS So far, there are 46 different formulas, 3 single herbs, and 24 compounds used in the treatment of various gynecological disorders such as premature ovarian failure, endometriosis breast cancer, and so on. Many experimental results have shown that TMs can regulate apoptosis, invasion, migration, oxidative stress, and the immune system. In addition, the effect of TMs in gynecological disorders treatment may be due to the regulation of VEGF, PI3K-AKT, MAPK, NF-κB, and other signaling pathways. Apparently, TMs play an active role in the treatment of gynecological disorders by regulating these signaling pathways. CONCLUSION TMs have a curative effect on the prevention and treatment of gynecological disorders. It could relieve and treat gynecological disorders through a variety of pathways. Therefore, the appropriate TM treatment program makes it more possible to treat gynecological disorders.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 333:118419. [PMID: 38838924 DOI: 10.1016/j.jep.2024.118419] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 05/20/2024] [Accepted: 06/02/2024] [Indexed: 06/07/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Heart failure with preserved ejection fraction (HFpEF) has emerged as a condition with high incidence and mortality rates in recent years. Dengzhan Shengmai capsule (DZSMC) is a Chinese patent medicine based on the classic recipe "Shengmai powder". The relevant Chinese medicine ratio of Erigeron breviscapus (Vaniot) Hand.-Mazz., Panax ginseng C.A.Mey., Schisandra chinensis (Turcz.) Baill., and Ophiopogon japonicus (Thunb.) Ker Gawl. is 30 : 6 : 6 : 11 . Traditional Chinese medicine (TCM) is being increasingly explored as a safe and effective treatment modality for HFpEF. Clinical studies have shown that DZSMCs can effectively treat heart failure, however, the mechanism of action of DZSMCs in the treatment of HFpEF are still not clear. AIM OF THE STUDY To investigate the efficacy and underlying mechanisms of Dengzhan Shengmai capsule (DZSMC), in the treatment of HFpEF by focusing on its ability to treat microvascular inflammation. MATERIALS AND METHODS First, the efficacy of DZSMCs against HFpEF was predicted by network pharmacology. After 3 days of adaptive feeding in SPF-grade polypropylene cages, the mice in the Model group, DZSMC group, and Captopli group underwent single kidney resection, and micropumps were implanted in their backs for continuous infusion of aldosterone at a rate of 0.3 μg/h for 4 weeks. Moreover, the mice were given DZSMCs or Captopli via oral gavage for four weeks. Overall, cardiac function was evaluated in mice, and cardiac ultrasound and blood biochemical indices were evaluated in HFpEF mice. RESULTS DZSMCs can ameliorate myocardial hypertrophy and cardiomyocyte damage caused by excessive myocardial stress, ultimately mitigating long-term cardiac impairment; it aids in the restoration of myocardial fibre proliferation and enhances mitochondrial morphology and function. In a murine model of ventricular hypertrophy and left ventricular dysfunction, which are indicative of cardiac insufficiency, the administration of DZSMCs resulted in notable improvements. Echocardiographic and overall assessments of cardiac function revealed a reduction in cardiac dysfunction and ventricular hypertrophy post-DZSMC intervention. Moreover, intervention with DZSMCs led to a reduction in the serum levels of several markers associated with chronic systemic inflammation, such as sST2, IL1RL1, CRP, and IL-6. Simultaneously, the levels of indicators of microvascular inflammation, including VCAM and E-SELECTIN, also decreased following DZSMC intervention. These findings suggest the potential multifaceted impact of DZSMCs in alleviating cardiac abnormalities, mitigating systemic inflammation, and reducing microvascular inflammatory markers, highlighting their promising therapeutic role in managing myocardial health. CONCLUSIONS These results provide novel evidence that DZSMCs improve HFpEF by regulating microvascular inflammation.

Abstract
Neuroinflammation caused by microglia in the central nervous system (CNS) is observed after myocardial infarction (MI). However, the inflammatory response mechanism remains unclear. BuChang Naoxintong capsule (NXT) is a Chinese medicine for treating ischemic cardio-cerebrovascular diseases, requiring more studies to understand the pharmacodynamic mechanism. Permanent ligation of the left anterior descending coronary artery (LAD) was performed in rats. Additionally, histopathological staining in the left ventricular (LV) and immunofluorescence within the brain cortex after 1 d and 7 d of MI were performed to determine the NXT pharmacodynamic action and best administration dosage. Proteomics helped obtain the essential proteins related to neuroinflammation and MI in the heart and brain tissue after 7 d of MI. Based on TTC, HE, Masson, and immunofluorescence staining results of CD206 and IBA-1, NXT demonstrated a better pharmacodynamic action towards myocardial injury and neuroinflammation after 7 d of MI. Moreover, the human equivalent dosage of NXT (220 mg/kg) became the best administration dose. The proteome bioinformatics analysis in the LV and brain cortex was performed. Thus, the elongation of very long-chain fatty acids protein 5 (ELOVL5) and ATP-binding cassette subfamily G member 4 (ABCG4) became critical proteins related to MI and neuroinflammation. The western blotting results indicated that ABCG4 expression possessed the same trend as the proteomics results. The auto-dock results revealed that ABCG4 had a good binding ability with Ferulic acid, Paeoniflorin, and Tanshinone II A, the key ingredients of NXT. The cellular thermal shift assay results demonstrated that ABCG4 showed better thermal stability post-NXT treatment. NXT can improve myocardial injury, such as heart infarct size, pathological injury, myocardial fibrosis, and inflammatory cell infiltration. Additionally, brain neuroinflammation induced by microglia after MI affects the expression and structure of ABCG4. Thus, ABCG4 could be the key protein associated with MI and neuroinflammation.

Abstract
Extracellular vesicles (EVs) have been recognized as one of the promising specific drugs for myocardial infarction (MI) prognosis. Nevertheless, low intramyocardial retention of EVs remains a major impediment to their clinical application. In this study, we developed a silk fibroin/hydroxypropyl cellulose (SF/HPC) composite hydrogel combined with AC16 cell-derived EVs targeted modification by folic acid for the treatment of acute myocardial infarction repair. EVs were functionalized by distearoylphosphatidyl ethanolamine-polyethylene glycol (DSPE-PEG-FA) via noncovalent interaction for targeting and accelerating myocardial infarction repair.In vitro, cytocompatibility analyses revealed that the as-prepared hydrogels had excellent cell viability by MTT assay and the functionalized EVs had higher cell migration by scratch assay.In vivo, the composite hydrogels can promote myocardial tissue repair effects by delaying the process of myocardial fibrosis and promoting angiogenesis of infarct area in MI rat model.

Abstract
Myocardial infarction (MI) induces neuroinflammation indirectly, chronic neuroinflammation may cause neurodegenerative diseases. Changes in the proteomics of heart and brain tissue after MI may shed new light on the mechanisms involved in neuroinflammation. This study explored brain and heart protein changes after MI with a data-independent acquisition (DIA) mode proteomics approach. Permanent ligation of the left anterior descending coronary artery (LAD) was performed in the heart of rats, and the immunofluorescence of microglia in the brain cortex was performed at 1d, 3d, 5d, and 7d after MI to detect the neuroinflammation. Then proteomics was accomplished to obtain the vital proteins in the heart and brain post-MI. The results show that the number of microglia was significantly increased in the Model-1d group, the Model-3d group, the Model-5d group, and the Model-7d group compared to the Sham group. Various proteins were obtained through DIA proteomics. Linking to key targets of brain disease, 14 proteins were obtained in the brain cortex. Among them, elongation of very long chain fatty acids protein 5 (ELOVL5) and ATP-binding cassette subfamily G member 4 (ABCG4) were verified through western blotting (WB). The results of WB were consistent with the proteomics results. Therefore, these proteins may be related to the pathogenesis of neuroinflammation after MI.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 125:155357. [PMID: 38295662 DOI: 10.1016/j.phymed.2024.155357] [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: 09/21/2023] [Revised: 01/02/2024] [Accepted: 01/11/2024] [Indexed: 02/13/2024]
Abstract
BACKGROUND The terminal stage of all cardiovascular diseases typically culminates in heart failure (HF), with no effective intervention available to halt its progression. LuQi formula (LQF) has been employed in clinical for numerous years to significantly ameliorate cardiac function in HF patients. Nevertheless, the underlying mechanism of LQF's efficacy remains inadequately comprehended. Cardiomyocyte ferroptosis has served as a pathogenic mechanism in HF. The goal of the current experiment was to ascertain whether LQF ameliorates HF by preventing cardiomyocyte ferroptosis and to elucidate the intrinsic mechanism involved. PURPOSE This research objective is to investigate the impact and underlying mechanism of LQF attenuating cardiomyocyte ferroptosis in heart failure. METHODS Transverse aortic constriction (TAC) was performed to construct the HF mouse model. Neonatal rat cardiomyocytes (NRCMs) were subjected to in vitro experiments. High-performance liquid chromatography (HPLC) identified the bioactive compounds in LQF. Transcriptomic and quantitative proteomic analyses revealed the potential targets of LQF anti-HF. Specifically, histological staining evaluated cardiac hypertrophy and fibrosis. Transmission electron microscopy (TEM) observed mitochondrial morphology. The content of Fe2+, ROS, MDA, GSH, and GSSH was detected using kits. Molecular docking evaluated the binding activities between essential active ingredients of LQF and critical proteins of cardiomyocyte ferroptosis. Mechanistically, the expression levels of Nrf2, Keap1, HO-1, SLC7A11, and GPX4 were evaluated using qPCR, Western blot (WB), or immunohistochemical staining. RESULTS The primary nine active ingredients in LQF were detected. Transcriptomic and proteomic analyses demonstrated that LQF may ameliorate HF by preventing cardiomyocyte ferroptosis. Histomorphometric analyses revealed that LQF attenuates myocardial hypertrophy and fibrosis. TEM revealed that LQF diminished mitochondrial shrinkage and increased membrane density in myocardial tissue. Additionally, LQF diminished reactive oxygen species (ROS) generation in cardiomyocytes and suppressed cardiomyocyte ferroptosis. Furthermore, the molecular docking technique revealed that the primary active ingredients of LQF had suitable binding activities with Nrf2, GPX4, and SLC7A11. Western analysis further verified that LQF activated the Nrf2/GPX4 signaling axis. decreased SLC7A11 and HO-1 expression. CONCLUSIONS These results demonstrated that LQF prevents cardiomyocyte ferroptosis via activating Nrf2/GPX4 signaling axis and suppressing SLC7A11 and HO-1 expression. Concurrently, it contributed to elucidating the intrinsic mechanism of LQF and provided a scientific rationale for its development as a novel cardiovascular therapeutic drug.
