Abstract
Targeted therapies using epidermal growth factor receptor (EGFR) inhibitors have markedly improved survival rates and quality of life for patients with EGFR-mutant lung adenocarcinoma (LUAD). Despite these advancements, resistance to EGFR inhibitors remains a significant challenge, limiting the overall effectiveness of the treatment. This study explored the synergistic effects of combining Paeoniae Radix (PR) with first-generation EGFR-tyrosine kinase inhibitors (TKIs), erlotinib and gefitinib, to overcome this resistance. Transcriptomic analysis of EGFR-mutant LUAD cell lines revealed that PR treatment could potentially reverse the gene signatures associated with resistance to EGFR-TKIs, primarily through the suppression of the Aurora B pathway. Experimental validation demonstrated that combining PR with erlotinib and gefitinib enhanced drug responsiveness by inhibiting Aurora kinase activity and inducing apoptosis in LUAD cells. Additionally, gene expression changes confirmed these combined effects, with the suppression of the Aurora B pathway and upregulation of the apoptotic pathway, which was accompanied by increased expression of multiple pro-apoptotic genes. Our findings contribute to the development of natural product-based therapeutic strategies to mitigate drug resistance in LUAD.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 331:118329. [PMID: 38750989 DOI: 10.1016/j.jep.2024.118329] [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: 02/27/2024] [Revised: 05/05/2024] [Accepted: 05/09/2024] [Indexed: 05/19/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Yiqitongmai decoction (YQTMD), a classic TCM, has been widely used in clinical treatment for MI. However, it is still difficult to clarify the potential active compounds and pharmacological mechanisms of it in treating MI. AIM OF THE STUDY To explore the active ingredients, pharmacological effects, potential targets and mechanisms of YQTMD against MI. MATERIALS AND METHODS Serum pharmacochemistry by UPLC-MS/MS was applied to analyze the phytochemical components in serum from YQTMD. These components were then used to predict the potential targets using network pharmacology approach and molecular dynamics simulations, and then the protective effect of them on H9c2 cells following hypoxic conditions was assessed. Afterwards, the pharmacological effects of YQTMD on MI in mice were tested by determining electrocardiogram (ECG), echocardiography, cardiac biomarkers, oxidative stress, inflammation and pathophysiological changes. The protein levels involving STAT3 signal were detected using Western blot and immunofluorescence assays. Furthermore, STAT3 inhibitor Sttatic was employed to further elucidate the underlying mechanisms. RESULTS Totally, 26 compounds derived from YQTMD were identified in mice serum, and 201 genes associated with the compounds were collected. The compounds including safflomin A, ferulic acid, gypenoside XVII, ginsenoside Rg1 and glycyrrhizic acid were identified as the critical compounds of YQTMD to regulate STAT3 pathway. In vitro, compounds combination significantly enhanced the viability of H9c2 cells and reduced ROS level compared to model cells. The in vivo results showed that YQTMD effectively reduced myocardial injury, as evidenced by the decreased serum cardiac injury markers, reduction in the size of myocardial infarct, restoration of abnormal alterations in ECG and decrease in cardiomyocyte apoptosis. Additionally, YQTMD attenuated MI-induced cardiac dysfunction, alleviated pathological changes, reduced MDA levels, and enhanced SOD and GSH levels compared with model mice. Significantly, the levels of IL-6, IL-1β, and TNF-α were observed to decrease in the YQTMD group. The expression levels of key proteins (p-STAT3, HIF-1α, NOX2, TLR5 and Caspase3) in STAT3 pathway were also regulated by YQTMD. However, the cardioprotective effects of YQTMD on MI were attenuated by STAT3 inhibitor Sttatic. CONCLUSIONS This study investigated the active ingredients and potential mechanisms of YQTMD for MI treatment based on serum pharmacochemistry and network pharmacology approaches, revealing that YQTMD exerts its therapeutic effects on MI by alleviating oxidative stress, inflammation and apoptosis through adjusting STAT3 signaling pathway.

[PMID: 38423407 DOI: 10.1016/j.jep.2024.117987] [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: 01/10/2024] [Revised: 02/23/2024] [Accepted: 02/25/2024] [Indexed: 03/02/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Paeoniae Radix Rubra (PRR) is the dried root of Paeonia lactiflora Pall, which has been widely used to anti-thrombotic, lipid-lowering, anti-spasmodic, antioxidant, antibacterial, hepatoprotective, and anti-tumor in Chinese clinical practice. Recent research has demonstrated that PRR plays a significant anti-tumor role in animal models of tumor-bearing. AIM OF THE STUDY There has not been the evaluation of the anti-tumor effects of PRR. This study conducts a meta-analysis to assess the anti-tumor efficacy of PRR on animal models, providing scientific evidence for clinical application of PRR in the adjuvant therapy of tumors. MATERIALS AND METHODS English databases (PubMed, The Cochrane Library, Embase, and Web of Science) and Chinese databases (CNKI, WanFang, SinoMed, CTSJ-VIP) were used to search all pertinent animal studies investigating the anti-tumor effects of PRR and its extracts. The quality of the included studies was evaluated using the SYRCLE animal experiment risk assessment tool, and statistical analysis was carried out using Revman 5.3 software. Egger's test and funnel plots were used to assess potential publication bias in the studies. RESULTS The initial search produced a total of 3905 potentially pertinent studies, and 24 studies met the inclusion criteria. These studies included animal tumor models of hepatocellular carcinoma, lung cancer, sarcoma, bladder cancer, leukemia, colon cancer, glioblastoma, and pancreatic cancer. The meta-analysis findings demonstrated that both PRR and its extracts significantly inhibited tumor growth in animals. Compared with the control group, PRR substantively inhibited tumor volume (SMD, -3.09; 95% CI, [-4.05, -2.13]; P < 0.0001), reduced tumor weight (SMD, -1.08; 95% CI, [-1.37, -0.78]; P < 0.0001), decreased tumor number (SMD, -2.16; 95% CI, [-3.45, -0.86]; P = 0.001), and prolonged the survival duration time (SMD, 0.97; 95% CI, [0.23, 1.71]; P = 0.01) on the experimental animals. CONCLUSIONS PRR displayed a potential therapeutic efficacy on eight tumors in animal models including hepatocellular carcinoma, lung cancer, sarcoma, bladder cancer, leukemia, colon cancer, glioblastoma, and pancreatic cancer. However, the quality and quantity of included studies may affect the accuracy of positive results. In the future, more high-quality randomized controlled animal experiments are need for meta-analysis.

Abstract
Introduction: Corydalis yanhusuo total alkaloids (CYTA) are the primary active ingredients in yanhusuo, known for their analgesic and cardioprotective effects. However, the mechanisms underlying the treatment of Myocardial ischemia (MI) with CYTA have not been reported. The purpose of this study was to explore the protective effect of CYTA on MI and its related mechanisms. Methods: A network pharmacology was employed to shed light on the targets and mechanisms of CYTA's action on MI. The protective effect of CYTA against hypoxia damage was evaluated in H9c2 cells. Furthermore, the effects of CYTA on L-type Ca2+ current (ICa-L), contractile force, and Ca2+ transient in cardiomyocytes isolated from rats were investigated using the patch clamp technique and IonOptix system. The network pharmacology revealed that CYTA could regulate oxidative stress, apoptosis, and calcium signaling. Cellular experiments demonstrated that CYTA decreased levels of CK, LDH, and MDA, as well as ROS production and Ca2+ concentration. Additionally, CYTA improved apoptosis and increased the activities of SOD, CAT, and GSH-Px, along with the levels of ATP and Ca2+-ATPase content and mitochondrial membrane potential. Moreover, CYTA inhibited ICa-L, cell contraction, and Ca2+ transient in cardiomyocytes. Results: These findings suggest that CYTA has a protective effect on MI by inhibiting oxidative stress, mitochondrial damage, apoptosis and Ca2+ overload. Discussion: The results prove that CYTA might be a potential natural compound in the field of MI treatment, and also provide a new scientific basis for the its utilization.

Abstract
BACKGROUND Every year, approximately 17 million people worldwide die due to coronary heart disease, with China ranking second in terms of the death toll. Myocardial ischemia-reperfusion injury (MIRI) significantly influences cardiac function and prognosis in cardiac surgery patients. Jiawei Danshen Decoction (JWDSD) is a traditional Chinese herbal prescription that has been used clinically for many years in China to treat MIRI. The underlying molecular mechanisms, however, remain unknown. To investigate the proteomic changes in myocardial tissue of rats given JWDSD for MIRI therapy-based proteomics. METHODS MIRI rat model was created by ligating/releasing the left anterior descending coronary artery. For seven days, the drugs were administered twice daily. The model was created following the last drug administration. JWDSD's efficacy in improving MIRI was evaluated using biochemical markers and cardiac histology. Tandem mass tag-based quantitative proteomics (TMT) technology was also used to detect proteins in the extracted heart tissue. To analyze differentially expressed proteins (DEPs), bioinformatics analysis, including gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathways, were employed. Furthermore, western blotting confirmed the potential targets regulated by JWDSD. RESULTS The histopathologic characteristics and biochemical data showed JWDSD's protective effects on MIRI rats. A total of 4549 proteins were identified with FDR (false discovery rate) ≤1%. Twenty overlapping were identified (162 DEPs and 45 DEPs in Model/Control or JWDSD/Model group, respectively). Of these DEPs, 16 were regulated by JWDSD. GO analysis provided a summary of the deregulated protein expression in the categories of biological process (BP), cell component (CC), and molecular function (MF). KEGG enrichment analysis revealed that the signaling pathways of neutrophil extracellular trap formation, RNA polymerase, serotonergic synapse, and linoleic acid metabolism are all closely related to JWDSD effects in MIRI rats. Furthermore, T-cell lymphoma invasion and metastasis 1 (TIAM1) was validated using western blotting, and the results were consistent with proteomics data. CONCLUSIONS Our study suggests that JWDSD may exert therapeutic effects through multi-pathways regulation in MIRI treatment. This work may provide proteomics clues for continuing research on JWDSD in treating MIRI.

Abstract
Ischemia/hypoxia (I/H)-induced myocardial injury has a large burden worldwide. Hesperetin (HSP) has a cardioprotective effect, but the molecular mechanism underlying this is not clearly established. Here, we focused on the protective mechanisms of HSP against I/H-induced myocardium injury. H9c2 cardiomyocytes were challenged with CoCl2 for 22 h to imitate hypoxia after treatment groups received HSP for 4 h. The viability of H9c2 cardiomyocytes was evaluated, and cardiac function indices, reactive oxygen species, apoptosis, mitochondrial membrane potential (MMP), and intracellular Ca2+ concentration ([Ca2+ ]i ) were measured. L-type Ca2+ current (ICa-L ), myocardial contraction, and Ca2+ transients in isolated ventricular myocytes were also recorded. We found that HSP significantly increased the cell viability, and MMP while significantly decreasing cardiac impairment, oxidative stress, apoptosis, and [Ca2+ ]i caused by CoCl2 . Furthermore, HSP markedly attenuated ICa-L , myocardial contraction, and Ca2+ transients in a concentration-dependent manner. Our findings suggest a protective mechanism of HSP on I/H-induced myocardium injury by restoring oxidative balance, inhibiting apoptosis, improving mitochondrial function, and reducing Ca2+ influx via L-type Ca2+ channels (LTCCs). These data provide a new direction for HSP applied research as a LTCC inhibitor against I/H-induced myocardium injury.

Abstract
Bergenin is a phenolic glycoside that has been reported to occur naturally in several plant species, reported as a cardioprotective. However, bergenin, one of the important phytochemicals in these plants, is still not reported as a cardioprotective. The present study was designed to investigate the cardioprotective effects of bergenin on isoproterenol-induced myocardial infarction in rats. Bergenin and atenolol were administered through intraperitoneal (i.p.) injection to Sprague Dawley (SD) rats in separate experiments for five (5) days. At the end of this period, rats were administered isoproterenol (80 mg/kg s.c.) to induce myocardial injury. After induction, rats were anaesthetized to record lead II ECG, then sacrificed, blood was collected to analyze cardiac marker enzymes, and a histopathological study of the heart tissues was also performed. Pretreatment with bergenin showed a significant decrease in ST-segment elevation, deep Q-wave, infarct size, and also normalized cardiac marker enzymes (cTnI, CPK, CK-MB, LDH, ALT, and AST), particularly at 3 mg/kg, as compared to isoproterenol treated group. Our findings revealed, for the first time, the use of glycoside bergenin as a potential cardioprotective agent against the isoproterenol-induced MI in rats.

Vasorelaxant and Antioxidant Effects of Aframomum pruinosum Gagnep. (Zingiberaceae) Seed Extracts May Mediate Their Cardioprotective Activity against Isoproterenol-Induced Myocardial Infarction. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:7257448. [PMID: 35186101 PMCID: PMC8853790 DOI: 10.1155/2022/7257448] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 01/08/2022] [Accepted: 01/21/2022] [Indexed: 01/17/2023]
Abstract
Aframomum pruinosum seeds are traditionally used in Cameroon to treat cardiac palpitations. The present work evaluates the cardioprotective effects of the aqueous (AE) and ethanolic (EE) extracts from A. pruinosum seeds against isoproterenol-induced myocardial infarction. Male Wistar rats were pretreated for 14 days with AE or EE at doses of 75 and 150 mg/kg/day or propranolol (10 mg/kg/day). On days 15 and 16, they were injected subcutaneously with isoproterenol (85 mg/kg/day). Blood pressure and heart rate were weekly recorded by tail-cuff plethysmography during pretreatment and 24 hours after the second dose of isoproterenol. At the end of the treatment period, serum Lactate Dehydrogenase (LDH), Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), cardiac nitric oxide (NO), myeloperoxidase (MPO), and oxidative stress parameters (SOD, catalase, MDA, and GSH) were assayed. Sections of left ventricle tissue were subjected to histological analysis. The vasorelaxant effects of cumulative concentrations of AE or EE (3–300 µg/mL) were evaluated on intact or endothelium-denuded isolated aorta rings precontracted with noradrenaline (1 µM). The vasorelaxant effects of the plant extracts were also tested in the presence of Nω-nitro-L-arginine methyl ester (L-NAME; 100 µM). AE and EE significantly prevented blood pressure decrease and heart rate increase elicited by isoproterenol. Both plant extracts inhibited the increase in ALT, AST, NO, and MPO but did not prevent LDH surge. Oxidative stress parameters were improved following A. pruinosum pretreatment. AE and EE highly reduced cardiomyocyte necrosis and fibrosis but did not prevent leukocyte infiltration. Both extracts induced a concentration-dependent vasorelaxation that was significantly inhibited by the destruction of the endothelium and by L-NAME. Extracts of A. pruinosum exhibited cardioprotective effects, and EE was the most active. The cardioprotective effects of A. pruinosum extracts could be ascribed to their antioxidant, antinecrotic, and endothelium-dependent vasorelaxant effects.

Abstract
Cerebral ischemic reperfusion injury (CI/RI) is a critical factor that leads to a poor prognosis in patients with ischemic stroke. It is an extremely complicated pathological process that is clinically characterized by high rates of disability and mortality. Current available treatments for CI/RI, including mechanical and drug therapies, are often accompanied by significant side effects. Therefore, it is necessary to discovery new strategies for treating CI/RI. Many studies confirm that Chinese herbal medicine (CHM) was used as a potential drug for treatment of CI/RI with the advantages of abundant resources, good efficacy, and few side effects. In this paper, we investigate the latest drug discoveries and advancements on CI/RI, make an overview of relevant CHM, and systematically summarize the pathophysiology of CI/RI. In addition, the protective effect and mechanism of related CHM, which includes extraction of single CHM and CHM formulation and preparation, are discussed. Moreover, an outline of the limitations of CHM and the challenges we faced are also presented. This review will be helpful for researchers further propelling the advancement of drugs and supplying more knowledge to support the application of previous discoveries in clinical drug applications against CI/RI.

Abstract
Gynura procumbens (GP) grows abundantly in Southeast Asia. The present work was conducted to investigate the cardioprotective potential of ethanol extract of GP on cardiac markers, antioxidant levels, and histopathology of isoproterenol-induced myocardial infarction (MI). A total of 36 adult Sprague Dawley rats were randomly divided into six groups. Treatments were given via oral gavage for 28 days: two groups were given normal saline 0.9%; two groups were given GP250 mg/kg/day; and two groups were given GP500 mg/kg/day. On day 27 and 28, MI was induced with a subcutaneous injection of 85 mg/kg isoproterenol. The rats were sacrificed 48 h after the 1st injection. Cardiac markers, lipid peroxidation, oxidative status, and histopathological analyses were evaluated. Isoproterenol significantly increased the levels of troponin T, creatine kinase MB isoenzyme (CKMB), lactate dehydrogenase (LDH), and malondialdehyde (MDA), whereas the level of superoxide dismutase (SOD), catalase, and glutathione peroxidase were significantly decreased. In addition, the histopathological findings showed a necrosis of the myocardium as evidenced by neutrophil infiltration, and interstitial oedema with acceleration of apoptosis in MI. Interestingly, treatment with GP restored the levels of troponin T, LDH, MDA, SOD, and catalase significantly. Moreover, GP preserved the myocardial architecture while decreasing both necrosis and apoptosis. GP has the potential to limit myocardial injury after MI, and this is most likely achieved through its modulation of antioxidant enzyme activities.

Abstract
Inflammasome-mediated pyroptosis can aggravate myocardial ischemia/reperfusion injury. Total glucosides of paeony (TGP) is widely used in anti-inflammation. This study investigated the effect of TGP on pyroptosis of hypoxia/reoxygenation (H/R)-induced cardiomyocytes. HL-1 cells were subjected to H/R treatment. H/R-induced cardiomyocytes were treated with TGP at different concentrations (50, 100, and 200 mg/kg). The viability of H/R-induced cardiomyocytes was measured. The levels of lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD), and reactive oxygen species (ROS) were determined. The activity of caspase-1, the expressions of NLRP3 and GSDMD-N, and the concentrations of IL-1β and IL-18 were examined. miR-181a-5p expression in H/R cardiomyocytes was determined. The targeting relationship between miR-181a-5p and adenylate cyclase 1 (ADCY1) was verified. Functional rescue experiments were performed to verify the effect of miR-181a-5p or ADCY1 on the pyroptosis of H/R cardiomyocytes. TGP enhanced H/R-induced cardiomyocyte viability in a dose-dependent manner, reduced LDH, MDA, and ROS levels, increased SOD level, decreased caspase-1 activity, reduced NLRP3 and GSDMD-N expressions, and inhibited IL-1β and IL-18 concentrations. TGP suppressed miR-181a-5p expression in H/R cardiomyocytes. miR-181a-5p targeted ADCY1. miR-181a-5p overexpression or ADCY1 inhibition reversed the inhibitory effect of TGP on the pyroptosis of H/R cardiomyocytes. Collectively, TGP alleviated the pyroptosis of H/R cardiomyocytes via the miR-181a-5p/ADCY1 axis.

Li P, Shen J, Wang Z, Liu S, Liu Q, Li Y, He C, Xiao P. Genus Paeonia: A comprehensive review on traditional uses, phytochemistry, pharmacological activities, clinical application, and toxicology. JOURNAL OF ETHNOPHARMACOLOGY 2021; 269:113708. [PMID: 33346027 DOI: 10.1016/j.jep.2020.113708] [Citation(s) in RCA: 52] [Impact Index Per Article: 17.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 12/09/2020] [Accepted: 12/15/2020] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Paeonia, which comprises approximately 52 shrubs or herbaceous perennials around the world, is the only genus of the Paeoniaceae and is pervasively distributed in Asia, southern Europe, and North America. Many species of the genus Paeonia have been used for centuries in ethnomedical medical systems. AIM OF THE REVIEW The present study aims to summarize the traditional uses, clinical applications, and toxicology of the genus Paeonia, to critically evaluate the state-of-the-art phytochemical and pharmacological studies of this genus published between 2011 and 2020, and to suggest directions for further in-depth research on Paeonia medicinal resources. MATERIALS AND METHODS Popular and widely used databases such as PubMed, Scopus, Science Direct, and Google Scholar were searched using the various search strings; from these searches, a number of citations related to the traditional uses, phytochemistry, biological activities, clinical application, and toxicology of the genus Paeonia were retrieved. RESULTS The use of 21 species, 2 subspecies, and 7 varieties of the genus Paeonia as traditional herbal remedies has been reported, and many ethnomedicinal uses, such as the treatment of hematemesis, blood stasis, dysmenorrhea, amenorrhea, epilepsy, spasms, and gastritis, have been recorded. The roots and root bark are the most frequently reported parts of the plants used in medicinal applications. In phytochemical investigations, 451 compounds have been isolated from Paeonia plants to date, which contains monoterpenoid glucosides, flavonoids, tannins, stilbenes, triterpenoids and steroids, and phenols. Studies of their pharmacological activities have revealed the antioxidant, anti-inflammatory, antitumour, antibacterial, antiviral, cardiovascular protective, and neuroprotective properties of the genus Paeonia. In particular, some bioactive extracts and compounds (total glucosides of peony (TGP), paeonol, and paeoniflorin) have been used as therapeutic drugs or tested in clinical trials. In addition to the "incompatibility" of the combined use of "shaoyao" and Veratrum nigrum L. roots in traditional Chinese medicine theory, Paeonia was considered to have no obvious toxicity based on the available toxicological tests. CONCLUSION A large number of phytochemical and pharmacological reports have indicated that Paeonia is an important medicinal herb resource, and some of its traditional uses including the treatment of inflammation and cardiovascular diseases and its use as a neuroprotective agent, have been partially confirmed through modern pharmacological studies. Monoterpenoid glucosides are the main active constituents. Although many compounds have been isolated from Paeonia plants, the biological activities of only a few of these compounds (paeoniflorin, paeonol, and TGP) have been extensively investigated. Some paeoniflorin structural analogues and resveratrol oligomers have been preliminarily studied. With the exception of several species (P. suffruticosa, P. ostii, P. lactiflora, and P. emodi) that are commonly used in folk medicine, many medicinal species within the genus do not receive adequate attention. Conducting phytochemical and pharmacological experiments on these species can provide new clues that may lead to the discovery of medicinal resources. It is necessary to identify the effective phytoconstituents of crude extracts of Paeonia that displayed pharmacological activities by bioactivity-guided isolation. In addition, comprehensive plant quality control, and toxicology and pharmacokinetic studies are needed in the future studies.

Abstract
Introduction: Isoprenaline or isoproterenol (1-(3,4-dihydroxyphenyl)-2-isopropylaminoethanolhydrochloride; ISO), a synthetic b-adrenergic agonist, can be used to establish myocardial ischemia, cardiotoxicity, necrosis and/or an experimental model of infarction in rats. Aim: Determination of the dynamics of myocardial injury biomarkers production of aspartate transaminase (AST), lactate dehydrogenase (LDH), creatine kinase (CK), and high-sensitive troponin T (hsTnT), with changes on electrocardiogram (ECG) parameters during the subcutaneous aplication of ISO in male Wistar rats. Material and methods: All animals (n = 23) were divided into two groups: control group (n = 11) treated with a saline solution, during two consecutive days (0,2 ml/kg b.m. daily, sc); and the ISO group (n = 12) treated with isoprenaline, during two consecutive days (85 mg/kg b.m. daily, sc). Blood was drawn from the rat tail vein in both groups, in order to determine serum activity levels of myocardial injury biomarkers, and an ECG (n = 6) was registered prior to the application, as well as 48h following the first dose of of saline solution or isoprenaline. Results: In comparison to the control group, in which no significant enzyme activities elevation (p > 0.05) nor ECG changes were registered, ISO group presented a significant rise of two clinically significant biomarkers of acute myocardial injury/myocardial infarction (AMI), CK (p = 0.05) and hsTnT (p < 0.01), as well as an ST segment elevation, with a patognomonic ECG change. Conclusion: Obtained results support previous studies, proving that isoprenaline represents an adequate experimental model for myocardial injury/AMI induction, and a "golden standard" for evaluating potential cardioprotective effects of pharmacological and non-pharmacological therapeutic modalities, with the ultimate goal of lowering the degree of lesions and improving post-infarction myocardium function.

Abstract
Carthamus tinctorius L.(Safflower), a herbal formula from Traditional Chinese Medicine (TCM), has been widely used for the treatment of cardio-cerebrovascular diseases, particularly cerebral infarction (CI) or cerebral ischemia-reperfusion injury. However, we know very little about the specific mechanisms associated with the therapeutic effect of Safflower on CI. In this study, we used a network pharmacology-based approach, together with rat model of CI, to gain more insight into of such mechanisms. Our analysis showed that Safflower contains 52 active compounds that target 247 genes, which were also cross-referenced with 299 genes associated with CI. Consequently, we identified 52 target genes in Safflower that were associated with CI. These 52 target genes were analyzed by gene ontology (GO) enrichment analysis, leading to the identification of 1491 biological process items, 90 molecular function items and 19 cell assembly items. Eighty-nine pathways were generated by KEGG enrichment (P < 0.05). Next, we investigated the effect of the extract of safflower (ES) and Safflower extract phospholipid complex (ESPC), delivered via the nasal route, on an animal model of the middle cerebral artery occlusion (MCAO). Our data confirmed that Safflower was able to treat CI by the regulating the TNF-α/MAPK pathway via CASP3. The therapeutic effect of ES and ESPC on CI acts by improving the circulation of blood in the central nervous system, reducing the inflammatory reaction, inhibiting apoptosis, and by protecting brain nerve cells from injury.

Abstract
The root of Paeonia lactiflora Pall. (Chishao, CS) and Ligusticum chuanxiong Hort. (Chuanxiong, CX) were widely used as a drug pair in Chinese Medicine, and the combination of CS and CX showed a more significant inhibition on neuronal apoptosis in our previous study. In the present study, total paeony glycosides (TPGs) from CS and total ligustici phenolic acids (TLPAs) from CX were combined to evaluate the synergistic effects against focal cerebral ischemia both in vitro and in vivo. The combination of TPGs and TLPAs at 7:3 had the best anti-oxidative stress and anti-inflammatory effect on OGD-induced HUVEC. Additionally, the infarction area proportion and neuron apoptosis of rats by TPGs:TLPAs (7:3) was significantly lower than their alone in MCAO rats. Moreover, TPGs: TLPAs of 7:3 showed a more significant effect on decreasing the expression of MMP-2 and MMP-9, and increasing the protein expression or mRNA level of TIMP-1 than other combinations. The optimal ratio of TPGs and TLPAs at 7:3 could bring more remarkable protective effects against focal cerebral ischemia in MCAO rats by alleviating oxidative stress, inflammatory and neuronal apoptosis to protect the blood-brain barrier. Overall, the present study provided benefical evidence for clinical application of CS and CX as a "drug pair".

Abstract
Oxidative stress plays an important role in the pathogenesis of myocardial infarction (MI). Schisandra chinensis bee pollen extract (SCBPE) possesses powerful antioxidant capacity. This study aimed to further explore the antioxidative and cardioprotective effects of SCBPE on acute MI induced by isoprenaline (ISO) in rats. The rats were intragastrically administrated with SCBPE (600, 1200, or 1800 mg/kg/day) and Compound Danshen dropping pills (270 mg/kg/day) for 30 days, then subcutaneously injected with ISO (65 mg/kg/day) on the 29th and 30th day. Compared with the model group, pretreatment with middle and high doses of SCBPE significantly reduced serum aspartate transaminase, lactate dehydrogenase, and creatine kinase activities and increased myocardial superoxide dismutase, glutathione peroxidase, and catalase activities. The histopathologic aspects showed that pathological heart change was found in the model group and reduced to varying degrees in the SCBPE groups. Moreover, the protein expression of nuclear factor-erythroid 2-related factor 2 (Nrf-2), heme oxygenase-1 (HO-1), and Bcl2 in the heart increased in the SCBPE groups, while that of Bax decreased compared to the model group. Besides this, uridine was isolated from S. chinensis bee pollen for the first time. This study could provide a scientific basis for using Schisandra chinensis bee pollen as a functional food for the prevention of MI.

[PMID: 30391709 DOI: 10.1016/j.jep.2018.10.041] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/27/2017] [Revised: 08/18/2018] [Accepted: 10/31/2018] [Indexed: 05/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Paeonia emodi Wall. ex Royle (peony) is an important member of family Paeoniaceae. Different parts of the plant have been folklorically used for treatment of different diseases. Infusion of dried flowers is used to treat diarrhea, the seeds are emetic and cathartic while the rhizome has been indicated for the treatment of hysteria, abdominal spasm, nervine tonic and headache. Besides these, peony has also been used in different respiratory and cardiovascular diseases (CVDs) like hypertension, palpitations, congestive heart failure and atherosclerosis. Being a folkloric remedy for the treatment of CVDs, Paeonia emodi (P. emodi) requires to be explored scientifically for MI management. AIM The current research work was designed to explore the possible cardioprotective mechanism of P. emodi in Isoproterenol hydrochloride (ISO) induced MI in mice. MATERIALS AND METHODS Experimental animals randomly divided in different groups, received methanolic extract of P. emodi (Pe.ME) and its subsequent fractions for 15 days followed by ISO (100 mg/kg s.c) at 24 h interval for two days. The cardioprotective potential of the test samples were investigated by determining the serum levels of Alanine Amino Transferase (ALT), Aspartate Amino Transferase (AST), Lactate Dehydrogenase (LDH) and Creatine Phosphokinase (CPK). The ethyl acetate fraction (Pe.EA) was found potent among all the tested samples of P. emodi. Based on its high potency, Pe.EA was subjected to GC-MS analysis and further relevant experiments including anti-hyperlipidemic, antioxidant, lipid peroxidation, membrane stabilization, thrombolytic, DNA ladder assay and histopathological study. RESULTS Pe.EA exhibited significant cardioprotective activity through reduction in levels of serum biomarkers responsible for MI. It significantly reduced serum levels of ALT (p < 0.001), AST (p < 0.001), CPK (p < 0.05) and LDH (p < 0.001) at a dose of 300 mg/kg as compared to ISO treated group. The GC-MS analysis confirmed the presence of potential compounds (esculetin, methyl eugenol, isovanillic acid) which might play a role in cardioprotection. Further screening confirmed that the effect of Pe.EA is mediated through multiple targets/mechanisms, which include anti-hyperlipidemia, antioxidant, lipid peroxidation inhibition, membrane stabilization, thrombolytic and DNA protective effects. Histopathological studies revealed the palliative effect for the damage caused in myocardial tissues. CONCLUSION Findings of current study provide evidence that P. emodi is a potential candidate for the treatment and management of MI.

[PMID: 30066927 PMCID: PMC6102630 DOI: 10.3892/mmr.2018.9335] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Accepted: 06/21/2018] [Indexed: 12/12/2022] Open
Abstract
At present, cardiovascular disease is the global leading cause of mortality. Total paeony glycoside (TPG) is a traditional Chinese medicine, which serves a pivotal role in the cardiovascular system. In the present study, the effects and underlying mechanisms of TPG on ischemia/reperfusion (I/R) injury-induced apoptosis of cardiomyocytes were investigated in vitro. Cell Counting kit-8 and flow cytometry were used to assess the viability, reactive oxygen species (ROS) content and apoptosis of H9C2 cells. The activities of lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GPX) were analyzed by commercial detection kits. Reverse transcription-quantitative polymerase chain reaction and western blot analysis were conducted to evaluate the expression levels of various factors. The results demonstrated that the viability of H9C2 cells was not significantly altered in response to various concentrations of TPG. However, following I/R injury, TPG markedly enhanced cell viability in a time- and dose-dependent manner. Furthermore, TPG decreased the rate of apoptosis and ROS levels, and reduced the activities of MDA and LDH. Conversely, TPG increased SOD and GPX activities. In addition, TPG upregulated the expression levels of pro-caspase-3 and B-cell lymphoma2 (Bcl-2), whereas it downregulated cleaved-caspase-3, poly (ADP-ribose) polymerase 1, Bcl-2-associated X protein, phosphorylated (p)-phosphatidylinositol 3 kinase (PI3K) and p-protein kinase B (Akt) expression. Treatment with insulin-like growth factor-1 increased the apoptosis of H9C2 cells, thus suggesting that activation of the PI3K/Akt signaling pathway reversed the protective effects of TPG. Taken together, TPG may suppress I/R-induced apoptosis and oxidative stress of H9C2 cells possibly by inhibiting the PI3K/Akt signaling pathway; such a phenomenon may have a therapeutic effect on cardiovascular disease.

Biotransformation of Dioscorea nipponica by Rat Intestinal Microflora and Cardioprotective Effects of Diosgenin. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2017; 2017:4176518. [PMID: 29085554 PMCID: PMC5632472 DOI: 10.1155/2017/4176518] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/09/2017] [Revised: 07/18/2017] [Accepted: 07/24/2017] [Indexed: 11/18/2022]
Abstract
Studying the biotransformation of natural products by intestinal microflora is an important approach to understanding how and why some medicines-particularly natural medicines-work. In many cases, the active components are generated by metabolic activation. This is critical for drug research and development. As a means to explore the therapeutic mechanism of Dioscorea nipponica (DN), a medicinal plant used to treat myocardial ischemia (MI), metabolites generated by intestinal microflora from DN were identified, and the cardioprotective efficacy of these metabolites was evaluated. Our results demonstrate that diosgenin is the main metabolite produced by rat intestinal microflora from DN. Further, our results show that diosgenin protects the myocardium against ischemic insult through increasing enzymatic and nonenzymatic antioxidant levels in vivo and by decreasing oxidative stress damage. These mechanisms explain the clinical efficacy of DN as an anti-MI drug.

Abstract
Modern medicine has been used to treat myocardial infarction, a subset of cardiovascular diseases, and have been relatively effective but not without adverse effects. Consequently, this issue has stimulated interest in the use of natural products, which may be equally effective and better tolerated. Many studies have investigated the cardioprotective effect of natural products, such as plant-derived phytochemicals, against isoproterenol (ISO)-induced myocardial damage; these have produced promising results on the basis of their antioxidant, anti-atherosclerotic, anti-apoptotic and anti-inflammatory activities. This review briefly introduces the pathophysiology of myocardial infarction (MI) and then addresses the progress of natural product research towards its treatment. We highlight the promising applications and mechanisms of action of plant extracts, phytochemicals and polyherbal formulations towards the treatment of ISO-induced myocardial damage. Most of the products displayed elevated antioxidant levels with decreased oxidative stress and lipid peroxidation, along with restoration of ionic balance and lowered expression of myocardial injury markers, pro-inflammatory cytokines, and apoptotic parameters. Likewise, lipid profiles were positively altered and histopathological improvements could be seen from, for example, the better membrane integrity, decreased necrosis, edema, infarct size, and leukocyte infiltration. This review highlights promising results towards the amelioration of ISO-induced myocardial damage, which suggest the direction for future research on natural products that could be used to treat MI.

Crude terpene glycoside component from Radix paeoniae rubra protects against isoproterenol-induced myocardial ischemic injury via activation of the PI3K/AKT/mTOR signaling pathway. JOURNAL OF ETHNOPHARMACOLOGY 2017; 206:160-169. [PMID: 28549860 DOI: 10.1016/j.jep.2017.05.028] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/25/2016] [Revised: 05/01/2017] [Accepted: 05/22/2017] [Indexed: 06/07/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Radix paeoniae rubra, also known as chishao (CS), is a frequently used traditional Chinese medicine that can promote blood circulation to remove blood stasis. It has been widely used for the prevention and treatment of cardiovascular diseases in China. Although terpene glycoside (TG), the major component in CS, has been shown to possess cardioprotective properties, the mechanism underlying CS-TG's preventive effect against myocardial ischemia injury is unknown. This study was conducted to explore the protective and curative effects of CS-TG against isoproterenol (ISO)-induced myocardial ischemic injury in rats and investigate the underlying myocardial protective mechanisms. MATERIALS AND METHODS A rat model of ISO-induced myocardial ischemia was established to evaluate the protective effect of CS-TG in ameliorating heart injury. Myocardial ischemia was induced by administering ISO (40mg/kg/d) subcutaneously for 2 days. Serum was collected and analyzed for the levels of different cardiac biomarkers, and heart tissues were isolated and prepared for ATP analysis, glycogen content determination, histopathology assay, and ultrastructure observation. The regulatory effects of CS-TG on myocardial apoptosis in rats were studied by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining, and the levels of cleaved caspase-3, Bax, and Bcl-2 were detected by western blotting. Furthermore, in vitro experiments were conducted to examine whether the CS-TG's cardioprotective effects were linked to the inhibition of apoptosis via activation of the phosphoinositide-3-kinase/serine-threonine kinase AKT/mammalian target of rapamycin (PI3K/AKT/mTOR) pathway. RESULTS CS-TG (300mg/kg/d) significantly decreased serum levels of creatine kinase and lactate dehydrogenase in ISO-induced myocardial ischemic rats. Analysis of ATP and glycogen contents, myocardial ultrastructure, and pathological examination showed that CS-TG (300mg/kg/d) significantly improved energy metabolism and alleviated myocardial injury in vivo. In addition, the expression of p-AKT and p-mTOR in rats subjected to CS-TG significantly elevated, while the levels of caspase-3 and Bax/Bcl-2 dramatically reduced. Moreover, treatment with LY294002, a PI3K inhibitor, abrogated CS-TG (200μg/mL) induced down-regulation of cleaved caspase-3, Bax/Bcl-2 in the serum. CONCLUSIONS CS-TG protects the heart from ISO-induced myocardial ischemia, potentially by improving cardiac energy metabolism and inhibiting cardiomyocyte apoptosis via activation of the PI3K/AKT/mTOR signaling pathway. Thus, CS -TG might be a potential therapeutic candidate for the prevention and treatment of myocardial ischemia.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Yujin Powder (YJP), an old prescription, is one of the most classical prescription for treating the large intestine dampness-heat syndrome (LIDHS). However, its potential modern pharmacological mechanisms remain unclear. AIM OF THE STUDY The present study was designed to explore the essence of LIDHS and treatment mechanisms of the YJP on the LIDHS. METHODS The rat model of LIDHS was established by such complex factors as high-sugar and high-fat diet, improper diet, high temperature and humidity environment (HTHE), drinking and intraperitoneal injection of Escherichia coli., which imitated the inducing conditions of LIDHS. Then the clinical symptoms and signs, blood routine, blood biochemistry, whole blood viscosity (WBV), serum inflammatory cytokines levels and the histopathological changes of main organs were detected and observed, respectively. RESULTS The results showed that the clinical symptoms and signs of the model rats were consistent with the diagnostic criteria of LIDHS, moreover, there were obvious systemic inflammatory response and extensive congestion. And after treatment with YJP in different dosages, the clinical symptoms and signs of the rats with LIDHS were improved; the indexes of blood routine and blood biochemistry and inflammatory cytokines levels tended to be normal; the WBV decreased and histopathological changes of major organs were alleviated or returned to normal. There was an obvious dose-effect relationship, and the high dose of YJP (HD-YJP) had the best treatment effects. CONCLUSIONS These results suggested that in LIDHS, diarrhea was the major clinical manifestation; the large intestine was the main lesion area; mucosa injury, inflammation and congestion of the large intestine with systemic inflammatory response and congestion were the most typical pathological characteristics. Meanwhile, YJP exhibited the comprehensive effects of anti-diarrhea, anti-inflammation, lowering blood lipid, relieving blood stasis, repairing intestinal mucosa and regulation and protection of multiple organs on LIDHS. These findings provided not only important information for understanding the essence of LIDHS but also the theoretical basis for developing new-drugs for treating dampness-heat type of diarrheal diseases.

Abstract
PURPOSE Aerobic exercise may offer favorable effects for coronary perfusion in the myocardial ischemia area, although the underlying molecular mechanisms remain unclear. This study was designed to investigate the effect of aerobic exercise on the collateral circulation in the ischemia myocardium and to evaluate calcitonin gene-related peptide (CGRP) changes during this process. METHODS AND RESULTS Wistar rats were randomly divided into 3 groups of 7 rats each: a sham operated group (Sham), a myocardial ischemia-only group (MI) and a MI plus aerobic exercise group (MI+AE). The rat myocardial ischemia model was established by injecting isoprenaline (2mg/kg, i.p.). The aerobic exercise training consisted of swimming (40min/d, 5d/wk) for 4 weeks. At the end-points, after echocardiographic analysis was performed, blood and ischemia myocardium samples were collected and analyzed by ELISA to quantify the CGRP protein. The dorsal root ganglia were isolated and analyzed by reverse transcription polymerase chain reaction (RT-PCR) to examine the CGRP mRNA expression, and ischemia myocardium capillary density was evaluated by immunohistochemistry. Our data showed that the capillary density in the left ventricle and heart function were significantly decreased with decreased CGRP production in the MI rats, which were reversed by aerobic exercise in the MI+AE rats. CONCLUSION These results indicate that aerobic exercise may alleviate myocardial ischemia through collateral circulation development with increased CGRP production. CGRP may play an important role in developing the collateral circulation.

Cardioprotective effect of total saponins from three medicinal species of Dioscorea against isoprenaline-induced myocardial ischemia. JOURNAL OF ETHNOPHARMACOLOGY 2015; 175:451-5. [PMID: 26456366 DOI: 10.1016/j.jep.2015.10.004] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/29/2014] [Revised: 09/22/2015] [Accepted: 10/02/2015] [Indexed: 05/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As folk medicines used in China since 1950s, Dioscorea nipponica Makino (DN), D. panthaica Prain et Burkill (DP), and D. zingiberensis C.H. Wright (DZ) are regarded as having more or less the same traditional therapeutic actions, such as activating blood, relieving pain, and dispersing swelling. It is noteworthy that, of the 49 species of the genus Dioscorea distributed in China, based on such traditional efficacies, only these three have been further developed as effective single-herb medicines for treating cardiovascular diseases by the modern pharmaceutical industry. In our previous study, it was found that the chemical compositions of DN and DP were similar, and both were distinct from that of DZ. Hence, whether their different chemical profiles support their anti-IHD (ischemic heart disease) activity in common still needs to be answered. So far it is still unknown whether the efficacies of these three herbs act via similar mechanism and whether they possess comparable therapeutic efficacy for experimental myocardial ischemia (MI). AIM OF THE STUDY The present study aimed to further investigate the underlying mechanisms with respect to antioxidative stress activity by which these Dioscorea spp. attenuate MI, and to compare the therapeutic effect of total saponins from these three species on myocardial antioxidant levels and myocardial histology. MATERIAL AND METHODS The serum levels of creatine kinase (CK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), total superoxide dismutases (SOD), catalase (CAT), glutathione peroxidase (GPx), the total antioxidant capacity (T-AOC), and malondialdehyde (MDA), as well as myocardial histology, were compared among rat groups administered with total saponins (TS) of DN, DP or DZ (abbreviated as DNTS, DPTS and DZTS, respectively). The rats experienced myocardial ischemia induced by isoprenaline (ISO) injection; the test solutions (DNTS, DPTS, DZTS) were administered either after the ISO injection, or both before and after. RESULTS Compared with the model group (ISO injection only), TS groups exhibited significantly reduced activities of CK, LDH and AST, lowered level of MDA, and increased activities of SOD, CAT, GPx and T-AOC; heart tissues from TS groups revealed less severe histological damage. The cardioprotective efficacy of these three Dioscorea TS for rat MI was closely comparable based on the above observations. CONCLUSION The findings of the present study provide evidence that the anti-MI effect of DNTS, DPTS and DZTS can be attributed to the increase of myocardial antioxidant levels and decrease of lipid peroxidation formation, and the closely comparable results observed from these three Dioscorea saponins thereby explains the similarity in their clinical efficacy as anti-MI drugs.

Abstract
Total paeony glucosides (TPG) extracted from the roots of Radix Paeoniae Rubrae, have been approved for the therapy of rheumatoid arthritis by the State Food and Drug Administration. We previously demonstrated the myocardial protective effects of TPG in both isoprenaline-induced myocardial ischemia rat and acute myocardial infarction rat. However, the underlying mechanism of TPG effect in cardiomyocytes remains to be investigated. The aims of this study were to elucidate the effect of TPG on the activities of antioxidant defense targets and the bioenergetic system in rat cardiomyocytes. The changes of viability, antioxidant defense system activities, protein contents, and mitochondrial functions in tert-butyl hydroperoxide challenged H9c2 rat cardiomyoblasts were evaluated. The results suggest that TPG ameliorated cardiomyoblast dysfunction by preserving antioxidant defense and bioenergetic system.

Abstract
This study aims to evaluate the protective effects of Yi-Qi-Fu-Mai sterile powder (YQFM) on myocardial oxidative damage and tries to identify the active components responsible for its pharmacological benefits. YQFM and the n-butanol extract of YQFM (YQFM-Bu) were administered to ISO-induced myocardial injury mice. Left ventricle weight index and histopathological analyses were conducted. Serum enzymatic activities of lactate dehydrogenase (LDH), creatine kinase (CK) and superoxide dismutase (SOD), myeloperoxidase (MPO), and the levels of malondialdehyde (MDA) were also measured. Our results demonstrated that both YQFM and YQFM-Bu significantly restored the abnormal activities of CK, LDH, MPO, SOD, and the levels of MDA in ISO-induced myocardial injury mice, and these biochemical results were further supported by histopathological data. Our in vitro findings also confirmed that both YQFM and YQFM-Bu exhibit significant radical scavenging activity. Furthermore, the major active fractions of YQFM were identified by UPLC-MS/MS. Twenty-five ginsenosides and three lignans were identified from YQFM-Bu. These findings suggested YQFM-Bu is the major active fraction of YQFM with the ginsenosides and lignans as potential active components responsible for its protective effect against myocardial injury, and YQFM exerted its beneficial effects on myocardial injury mainly through inhibiting oxidative damage and maintaining the functional integrity of myocardial tissue.
