Compound Dan Zhi tablet attenuates experimental ischemic stroke via inhibiting platelet activation and thrombus formation. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2020; 79:153330. [PMID: 32932202 DOI: 10.1016/j.phymed.2020.153330] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 08/09/2020] [Accepted: 08/17/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND Compound Dan Zhi tablet (DZT) is a commonly used traditional Chinese medicine formula. It has been used for the treatment of ischemic stroke for many years in clinical. However, its pharmacological mechanism is unclear. PURPOSE The aim of the current study was to understand the protective effects and underlying mechanisms of DZT on ischemic stroke. METHODS Fifteen representative chemical markers in DZT were determined by ultra-performance liquid chromatography coupled with tandem quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS). The protective effect of DZT against ischemic stroke was studied in a rat model of middle cerebral artery occlusion (MCAO), and the mechanism was further explored through a combination of network pharmacology and experimental verification. RESULTS Quantitative analysis showed that the contents of phenolic acids, furan sulfonic acids, tanshinones, flavonoids, saponins and phthalides in DZT were calculated as 7.47, 0.788, 0.627, 0.531 and 0.256 mg/g, respectively. Phenolic acids were the most abundant constituents. Orally administered DZT (1.701 g kg-1) significantly alleviated the infarct size and neurological scores in MCAO rats. The network analysis predicted that 53 absorbed active compounds in DZT-treated plasma targeted 189 proteins and 47 pathways. Ten pathways were associated with anti-platelet activity. In further experiments, DZT (0.4 and 0.8 mg mL-1) markedly inhibited in vitro prostaglandin G/H synthase 1 (PTGS1) activity. DZT (0.4 and 0.8 mg mL-1) significantly inhibited in vitro platelet aggregation in response to ADP or AA. DZT (113 and 226 mg kg-1, p.o.) also produced a marked inhibition of ADP- or AA-induced ex vivo platelet aggregation with a short duration of action. DZT decreased the level of thromboxane A2 (TXA2) in MCAO rats. In the carrageenan-induced tail thrombosis model and ADP-induced acute pulmonary thromboembolism mice model, DZT (113 and 226 mg kg-1, p.o.) prevented thrombus formation. Importantly, DZT (113 and 226 mg kg-1, p.o.) exhibited a low bleeding liability. CONCLUSION DZT protected against cerebral ischemic injury. The inhibition of TXA2 level, platelet aggregation and thrombosis formation might involve in the protective mechanism.

Abstract
Salvia miltiorrhiza (Danshen), as an important traditional Chinese medicinal plant, has been used in China for the treatment of cardiovascular diseases for hundreds of years. Salvianolic acids (salvianolic acid A and salvianolic acid B) as the most abundant water-soluble component extracted from Salvia miltiorrhiza have attracted more and more attention from cardiovascular scientists due to its comprehensive cardiovascular actions. In vivo and in vitro studies have rendered salvianolic acid an excellent drug candidate for the treatment and prevention of cardiovascular diseases. In this review, we surveyed the protective effects of salvianolic acid A and salvianolic acid B against cardiovascular diseases and the pharmacological basis, providing a strong scientific rationale for elucidating the important role of Salvia miltiorrhiza in cardiovascular therapy. More importantly, we also hope to provide new inspiration and perspectives on the development and innovation of small-molecule cardiovascular drugs based on salvianolic acid.

Abstract
Panax notoginseng (Burk.) F.H. Chen has long been used to stop bleeding for hundreds of years in China. At present, only dencichine, notoginsenoside Ft1, and 20(S)-protopanaxadiol (PPD) showed hemostatic effect. However, the molecular mechanism of PPD on the platelet aggragetion needs to be further investigated. The study aims to evaluate the hemostatic effect of PPD and reveal its interacting targets using a series of experiments. In this study, the bleeding time was measured in mouse tail amputation and liver scratch models to evaluate hemostatic effect of PPD. The routine blood and plasma coagulation parameters in NS, HC, and PPD (2, 4, and 8 mg/kg) groups were measured using a blood analyzer. Platelet aggregation rate and ATP release were analyzed by a platelet aggregometer. Subsequently, the degranulation marker CD62P and PAC-1, and the concentrations of cytosolic Ca2+ ([Ca2+]i), cAMP, cGMP, and PAC-1 expressions were also assessed. We found that PPD shorted the bleeding time on the mouse tail amputation and liver scratch models and mainly increased blood platelet count in the rats after subcutaneous injection for 4 h. Meanwhile, PPD decreased APTT, increased FIB content, and directly induced platelet aggregation in vitro. In the absence of Ca2+, PPD induced the increase of [Ca2+]i and slightly increased the levels of CD62P and PAC-1. After the addition of 1 mM Ca2+, PPD treatment markedly promoted platelet activation by promoting ATP level, releasing CD62P and increasing PAC-1 binding in washed platelets. Excitingly, PPD-induced changes including platelet aggregation, decreased cAMP content, and the increases of CD62P and PAC-1 were significantly reversed by protease-activated receptor 1 (PAR-1) antagonist, vorapaxar, which showed similar function as thrombin. In addition, molecular docking analysis and ELISA assay demonstrated that PPD had a promising docking score with -6.6 kcal/mol and increased PAR-1 expression in human platelets, which indicated that PAR-1 is involved in PPD-induced platelet aggregation by regulating calcium signaling. Collectively, our study could provide the new insights of PPD as an essential hemostatic ingredient in Panax notoginseng for the treatment of hemorrhagic disease.

Exploring the protective effects of Danqi Tongmai tablet on acute myocardial ischemia rats by comprehensive metabolomics profiling. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2020; 74:152918. [PMID: 30979691 DOI: 10.1016/j.phymed.2019.152918] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/02/2019] [Revised: 04/02/2019] [Accepted: 04/03/2019] [Indexed: 05/25/2023]
Abstract
BACKGROUND Danqi Tongmai tablet (DQTM), a combination of salvianolic acids (SA) and panax notoginsenosides (PNS), is now in phase II clinical trial developed for the treatment of cardiovascular diseases. However, the mechanisms of its protective effects through regulating endogenous metabolites remain unclear. PURPOSE The purpose of this study was to explore the protective effects of DQTM on acute myocardial ischemia rats by comprehensive metabolomics profiling. STUDY DESIGN The rats were divided into three groups: sham-operating, acute myocardial ischemia (AMI) and DQTM groups. The plasma and heart were collected and profiled by LC-MS based metabolomics and lipidomics. Based on the identified differential metabolites, the pathway analysis results were obtained and further validated using the network pharmacology approach. METHODS The AMI model was induced by ligating the left anterior descending coronary artery. The metabolomics and lipidomics profiling were based on two established LC-QTOF/MS analysis methods. The raw data were processed using XCMS Online, then the differential metabolites with nonparametric t-test p value less than 0.05 were selected and identified using HMDB and METLIN. The pathway analysis was conducted using MetaboAnalyst and validated with the predicted network results obtained by BATMAN-TCM. RESULTS The metabolomics and lipidomics profiles of plasma and heart in response to AMI and DQTM were significantly different. The AMI operation had a serious influence on metabolites in heart ischemia region, while DQTM had a greater impact on lipids in heart non-ischemia region. A total of 151 differential metabolites were identified, including mainly amino acids and fatty acids. Multiple metabolic pathways were disturbed after AMI and could be restored by DQTM, of which arachidonic acid metabolism was further validated with the predicted results of network pharmacology. CONCLUSION The protective effects of DQTM on acute myocardial ischemia rats could be achieved through the regulation of multiple metabolic pathways.

Abstract
Various bioactive ingredients have been extracted from Chinese herbal medicines (CHMs) that affect tumor progression and metastasis. To further understand the mechanisms of CHMs in cancer therapy, this article summarizes the effects of five categories of CHMs and their active ingredients on tumor cells and the tumor microenvironment. Despite their treatment potential, the undesirable physicochemical properties (poor permeability, instability, high hydrophilicity or hydrophobicity, toxicity) and unwanted pharmacokinetic profiles (short half-life in blood and low bioavailability) restrict clinical studies of CHMs. Therefore, development of liposomes through relevant surface modifying techniques to achieve targeted CHM delivery for cancer cells, i.e., extracellular and intracellular targets and targets in tumor microenvironment or vasculature, have been reviewed. Current challenges of liposomal targeting of these phytoconstituents and future perspective of CHM applications are discussed to provide an informative reference for interested readers.

Abstract
BACKGROUND Laminaria japonica polysaccharide (LJP), a fucose enriched sulfated polysaccharide has been demonstrated to have excellent anticoagulant and antithrombotic activities. However, the antithrombotic effect of low molecular weight polysaccharide from enzymatically modified of LJP (LMWEP) remains unknown. MATERIAL AND METHODS LMWEP was prepared by fucoidanase enzymatic hydrolysis, and the antithrombotic and anticoagulant activities, and the underlying mechanism were investigated thoroughly. Rats were randomly divided into 6 groups (8 rats in each group): the blank control group, the blank control group treated with LMWEP (20 mg/kg), the model group, the model group treated with heparin (2 mg/kg), the model group treated with LJP (20 mg/kg), and the model group treated with LMWEP (20 mg/kg). After 7 days of intravenous administration, blood was collected for biochemical parameters examinations. RESULTS LMWEP increased the activated partial thromboplastin time (APTT), thrombin time (TT), prothrombin time (PT), 6-keto prostaglandin F1alpha (6-Keto-PGF1alpha), and endothelial nitric oxide synthase (eNOS). In addition, LMWEP decreased fibrinogen (FIB), endothelin-1 (ET-1), thromboxane B2 (TXB2), erythrocyte sedimentation rate (ESR), and hematocrit (HCT). CONCLUSIONS LMWEP, an enzymatically modified fragment with a molecular weight of 25.8 kDa, is a potential antithrombotic candidate for treatment of thrombosis related diseases.

Abstract
The compound Dan Zhi Tablet (DZT), a reputable traditional Chinese medicine prescription, is widely used for the treatment of ischemic stroke in clinic. However, its systematic chemical constituents have rarely been elucidated, which hampers its quality evaluation, the study of bioactive constituents and the mechanism of action interpretation. In this study, we developed a combination of multidimensional data acquisition and data processing strategy with the aim to globally and comprehensively identify the chemical constituents in DZT based on UPLC-TWIMS-QTOFMS. First, multidimensional acquisition modes (MSE, Fast DDA and HDMSE) were performed on UPLC-TWIMS-QTOFMS. Second, targeted characterizations of the known compounds and their analogues present in DZT were carried out on the basis of the corresponding commercial standards or Mass2Motifs. Third, untargeted identification of unknown compounds in DZT was performed by extracting shared Mass2Motifs from the raw fragmentation spectra. Finally, the coeluting isomers were characterized using a precursor and/or product ion mobility. Consequently, 202 compounds were detected from DZT: 29 of them were unambiguously identified by comparison with reference compounds, 29 unknown compounds were discovered in specific medicinal materials, and ten pairs of coeluting isomers, which could not be distinguished using conventional MSE or Fast-DDA, were resolved using HDMSE only. This strategy was successfully used for the rapid and global identification of complex compounds including known, unknown and coeluting isomeric compounds in DZT and provided helpful chemical information for further quality control, pharmacology and active mechanism research on DZT.

Abstract
Pulmonary arterial hypertension (PAH) is a severe disease characterized by
progressive remodeling of distal pulmonary arteries and persistent elevation of
pulmonary vascular resistance (PVR), which leads to right ventricular
dysfunction, heart failure, and eventually death. Although treatment
responsiveness for this disease is improving, it continues to be a
life-threatening condition. With the clinical efficacy of natural plant products
being fully confirmed by years of practice, more and more recognition and
attention have been obtained from the international pharmaceutical industry.
Moreover, studies over the past decades have demonstrated that drugs derived
from natural plants show unique advantages and broad application prospects in
PAH treatment, not to mention the historical application of Chinese traditional
medicine in cardiopulmonary diseases. In this review, we focus on summarizing
natural plant compounds with therapeutic properties in PAH, according to the
extracts, fractions, and pure compounds from plants into categories, hoping it
to be helpful for basic research and clinical application.

Front Physiol 2018; 9:491. [PMID: 29780330 PMCID: PMC5945866 DOI: 10.3389/fphys.2018.00491] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2018] [Accepted: 04/17/2018] [Indexed: 11/13/2022] Open
Abstract
Aim: Combined use of herbal medicines in patients underwent dual antiplatelet therapy (DAPT) might cause bleeding or thrombosis because herbal medicines with anti-platelet activities may exhibit interactions with DAPT. In this study, we tried to use a feedback system control (FSC) optimization technique to optimize dose strategy and clarify possible interactions in combined use of DAPT and herbal medicines. Methods: Herbal medicines with reported anti-platelet activities were selected by searching related references in Pubmed. Experimental anti-platelet activities of representative compounds originated from these herbal medicines were investigated using in vitro assay, namely ADP-induced aggregation of rat platelet-rich-plasma. FSC scheme hybridized artificial intelligence calculation and bench experiments to iteratively optimize 4-drug combination and 2-drug combination from these drug candidates. Results: Totally 68 herbal medicines were reported to have anti-platelet activities. In the present study, 7 representative compounds from these herbal medicines were selected to study combinatorial drug optimization together with DAPT, i.e., aspirin and ticagrelor. FSC technique first down-selected 9 drug candidates to the most significant 5 drugs. Then, FSC further secured 4 drugs in the optimal combination, including aspirin, ticagrelor, ferulic acid from DangGui, and forskolin from MaoHouQiaoRuiHua. Finally, FSC quantitatively estimated the possible interactions between aspirin:ticagrelor, aspirin:ferulic acid, ticagrelor:forskolin, and ferulic acid:forskolin. The estimation was further verified by experimentally determined Combination Index (CI) values. Conclusion: Results of the present study suggested that FSC optimization technique could be used in optimization of anti-platelet drug combinations and might be helpful in designing personal anti-platelet therapy strategy. Furthermore, FSC analysis could also identify interactions between different drugs which might provide useful information for research of signal cascades in platelet.

Abstract
Salvia miltiorrhiza Burge (Danshen) is an eminent medicinal herb that possesses broad cardiovascular and cerebrovascular protective actions and has been used in Asian countries for many centuries. Accumulating evidence suggests that Danshen and its components prevent vascular diseases, in particular, atherosclerosis and cardiac diseases, including myocardial infarction, myocardial ischemia/reperfusion injury, arrhythmia, cardiac hypertrophy and cardiac fibrosis. The published literature indicates that lipophilic constituents (tanshinone I, tanshinone IIa, tanshinone IIb, cryptotanshinone, dihydrotanshinone, etc) as well as hydrophilic constituents (danshensu, salvianolic acid A and B, protocatechuic aldehyde, etc) contribute to the cardiovascular protective actions of Danshen, suggesting a potential synergism among these constituents. Herein, we provide a systematic up-to-date review on the cardiovascular actions and therapeutic potential of major pharmacologically active constituents of Danshen. These bioactive compounds will serve as excellent drug candidates in small-molecule cardiovascular drug discovery. This article also provides a scientific rationale for understanding the traditional use of Danshen in cardiovascular therapeutics.

Discovery of a Novel ERp57 Inhibitor as Antiplatelet Agent from Danshen (Salvia miltiorrhiza). EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2018; 2018:9387568. [PMID: 29849736 PMCID: PMC5941821 DOI: 10.1155/2018/9387568] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/08/2017] [Revised: 02/02/2018] [Accepted: 03/11/2018] [Indexed: 01/03/2023]
Abstract
Danshen (Salvia miltiorrhiza) is a well-known herb in Traditional Chinese Medicine (TCM) for treating cardiovascular diseases, but the underlying mechanism remains to be fully elucidated. Here, we showed that Danshen and its active ingredient rosmarinic acid exhibited antiplatelet effects through the inhibition of ERp57, a member of protein disulfide isomerase (PDI) with potential roles in platelet aggregation. Danshen extract (DSE) exhibited potent inhibitory effects on the platelet aggregation induced by arachidonic acid- (AA-) induced platelet aggregation and the enzymatic activity of ERp57. Rosmarinic acid was identified by virtual screening and molecular docking as one of the hit compounds for ERp57. In line with this, rosmarinic acid displayed significant inhibitory effect on ERp57 activity and inhibited AA-induced platelet aggregation. Taken together, we demonstrated for the first time that DSE and rosmarinic acid displayed inhibitory effects on the catalytic activity of ERp57, providing evidence of the regulatory role of ERp57 underlying the antiplatelet effects of Danshen.

Abstract
For lead compound discovery from natural products, hollow fiber cell fishing with chromatographic analysis is a newly developed method. In this study, an adsorbed hollow fiber-based biological fingerprinting method was firstly developed to discover potential platelet aggregation inhibitors from Danshen-Honghua decoction. Platelets were seeded on the fiber and their survival rate was tested. Results indicated that more than 92% platelets survived during the whole operation process. Ranitidine and tirofiban were used as positive and negative control respectively to verify the reliability of the presented approach. The main variables such as amount of extract and stirring time that affect the adsorbed hollow fiber-based biological fingerprinting process were optimized, and the repeatability of this method was also investigated. Finally, 12 potential active compounds in Danshen-Honghua decoction were successfully detected using the established approach and structures for nine of them were tentatively identified by liquid chromatography with mass spectrometry analysis. In addition, the in vitro platelet aggregation inhibition test was carried out for five of the nine hit compounds, and three active components, namely, lithospermic acid, salvianolic acid A, and salvianolic acid B were confirmed. These results proved that the proposed method could be an effective approach for screening platelet inhibitors from plant extracts.

Abstract
Autologous fat particle transplantation has been widely used by surgeons. The present study evaluated the effect of Notoginsenoside R1 (NR1) treatment on rat autologous fat graft, along with the quality and retention rates. Male Sprague‑Dawley rats (n=60) received fat particle auto‑transplantation from the left abdominal cavity into lateral dorsum. A total of 14 days after surgery, NR1 in different doses (50, 100 and 200 mg/kg/day) was injected into rats, following which blood and fat graft samples were harvested at days 7, 14 and 28. Assessments were carried out by hematoxylin and eosin staining, western blotting, ELISA and immunohistochemistry (IHC). The survival rate of fat grafts was increased in three experimental groups, as detected by weight measurement. Histological scoring demonstrated that there were significant differences in tissue integrity between the 100 mg/kg/day group and the other 3 groups. hepatocyte growth factor, vascular endothelial growth factor, fibroblast growth factor, angiotensin and S100 levels in the 100 mg/kg/day NR1 group was increased compared with the other 2 treatment groups; however, all 3 treatment groups demonstrated increased expression of these proteins compared with the control group. Additionally, cluster of differentiation (CD)68 exhibited negative expression and CD31 showed weakly positive expression in all three experiments, as assessed by IHC. In conclusion, 100 mg/kg/day NR1 may potentially promote the retention rate and enhance the quality of autologous fat grafts via increasing vascularity in the recipient site. These results implicate NR1 as a therapeutic strategy for the improvement of outcome following fat graft surgery.

Abstract
BACKGROUND Panax notoginseng saponins, a traditional Chinese medicine extraction, and aspirin are both widely used to treat cerebral infarction in China. Good results in clinical practice have been achieved, when Panax notoginseng saponins was taken together with aspirin. METHODS To investigate the interaction of the two drugs in vivo, the concentration of notoginsenoside R1, ginsenoside Rg1, Rb1, Re and Rd. in blood were simultaneously measured by UPLC/MS/MS. Sample preparation was carried out by the protein precipitation technique with an internal standard saikosaponin A standard. The separation of six components was achieved by using an ACQUITY UPLC ®BEH C18 column (1.7μm 2.1×100mm) by gradient elution using water (containing 0.2% formic acid) and acetonitrile (containing 0.2% formic acid) as the mobile phase at a flow rate of 0.2mL/min. The pharmacokinetic parameters were determined using non-compartmental analysis. The transport of notoginsenoside R1, ginsenoside Rg1, Rb1, Re and Rd. in MDCK -MDR1 cell monolayer was also used to verify the conclusion of pharmacokinetic drug-drug interaction and study the mechanism of drug interaction. RESULTS The concentrations of the five components increased in a certain extent when the two drugs administered together in rats. The values of apparent permeability coefficients were significantly increased when the two drugs were used together. Aspirin and salicylic acid could destroy the tight junction protein and open the intercellular space to increase the absorption of Panax notoginseng saponins. CONCLUSION Pharmacokinetic drug-drug interaction in vivo existed between Panax notoginseng saponins and aspirin. The drug-drug interaction mainly occurred in the process of absorption.

Abstract
The blackberry seed was typically removed as a byproduct and waste from blackberry fruits for juices. Developing value-added utilization of berry seeds will significantly expand the market for berry products as well as improve benefit to berry producers. However, the research on blackberry seed is limited. The objective of this paper was to research antithrombotic mechanism of polysaccharides in blackberry seeds. Polysaccharides in blackberry seeds were extracted, purified and identified by high-performance gel permeation chromatography (HPSEC), gas chromatography (GC), fourier transform infrared (FT-IR) spectrometer and nuclear magnetic resonance spectra (NMR). Anticoagulant activities were evaluated in vivo by measuring activated partial thromboplastin time (APTT), thrombin time (TT), prothrombin time (PT), fibrinogen (FIB) and plasma recalcification time (RRT). Four polysaccharides named BSP-1a, BSP-1b, BSP-2 and BSP-3 were isolated from Blackberry (Rubus spp.) seeds. The results indicated that BSP-1b, BSP-2 and BSP-3 exhibited the anticoagulant activity. Therefore, the anti-thrombosis effects of BSP-1b, BSP-2 and BSP-3 were investigated in vivo by 6-Keto-PGF1α, thromboxane B2 (TXB2), endothelial nitric oxide synthase (eNOS), endothelin-1 (ET-1), whole blood viscosity (WBV), plasma viscosity (PV), hematocrit (Hct), erythrocyte sedimentation rate (ESR), APTT, TT, PT and FIB. The results suggested that BSP-1b, BSP-2 and BSP-3 had the inhibition effect on thrombus formation, and the antithrombotic effects were associated with the regulation of vascular endothelium active substance, activating blood flow and anticoagulation effect.

Abstract
The purpose of this study was to investigate the effects of salvianolic acid A (SAA) in systemic lupus erythematosus (SLE) induced by pristane in BALB/c mice. Lupus mice were established by confirming elevated levels of autoantibodies and IL-6 after intraperitoneal injection of pristane. Mice were then treated with daily oral doses of SAA for 5 months in parallel with mice treated with prednisone and aspirin as positive controls. The levels of autoantibodies were monitored at monthly intervals and nephritic symptoms observed by hematoxylin and eosin (H&E) and periodic acid–Schiff (PAS) staining. Western blot analysis of renal tissue was also employed. SAA treatment caused a significant reduction in the levels of anti-Sm autoantibodies and reduced renal histopathological changes and pathological effects. SAA treatment also significantly inhibited the phosphorylation of IKK, IκB and NFκB in renal tissues of lupus mice. In conclusion, the results suggest that SAA alleviates renal injury in pristane-induced SLE in BALB/c mice through inhibition of phosphorylation of IKK, IκB and NFκB.

Abstract
Stenosis of the coronary artery has been considered as an essential component of ischemic heart disease (IHD). Consequently, revascularization [e.g., percutaneous coronary intervention (PCI) and coronary artery bypass] has been the primary therapeutic approach to IHD. Such strategy has indeed revolutionized the management of IHD patients. However, not all patients with myocardial ischemia have visible coronary stenosis. Moreover, cardiovascular events occur in nearly 20% patients with stable coronary artery disease who have undergone PCI. The recently proposed "solar system" hypothesis of IHD postulates that coronary stenosis is only one (albeit important) of its features. Mechanistic contribution and clinical implication of multiple pathophysiological processes beyond coronary stenosis are highlighted in this hypothesis. On the basis of a holistic regulation and individualized medicine, Chinese medicine (CM) has been used in the real-world setting to manage a variety of diseases, including IHD, for more than two thousands years. In this article, we summarize the evidence of CM that supports the "solar system" IHD hypothesis, and argue for a comprehensive approach to IHD. At the theoretical level, the central features of this approach include a holistic view of disease and human subjects, as well as individualized medicine. At the practical level, this approach emphasizes anoxia-tolerance and self-healing.

Abstract
BACKGROUND MicroRNAs (miRNAs) are a novel class of powerful, endogenous regulators of gene expression. This study was designed to ascertain if miR-30a is involved in the cardioprotective actions of salvianolic acid B (Sal B) against myocardial ischemia-reperfusion (I-R) injury through suppression of autophagy. METHODS Murine myocardial cells that had undergone primary culture were induced by I-R and incubated with Sal B (25, 50, 100 μM) in the presence of a miR-30a mimic or miR-30a inhibitor. Expression of miR-30a, beclin-1, LC3-II and p-Akt protein, cell viability, and lactic acid dehydrogenase (LDH) release were assessed. RESULTS miR-30a expression was down-regulated remarkably in I-R cells, and this suppression could be reversed by Sal B in a dose-dependent manner. Sal B repressed autophagy in I-R myocardial cells. Sal B improved cell viability and reduced the rate of LDH leakage, which suggested that autophagy suppression was beneficial for cell survival. Knockdown of miR-30a with a miR-30a inhibitor could reverse the anti-autophagy effect of Sal B against I-R injury. Furthermore, we confirmed that Sal B has a protective role in miR-30a-mediated autophagy through the PI3K/Akt signaling pathway, which was abrogated by the PI3K inhibitor LY294002. CONCLUSIONS These data suggest that miR-30a is involved in Sal B-mediated cardioprotection against I-R injury through the PI3K/Akt signaling pathway.

Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) is a fatal disease characterized by increased pulmonary arteriolar resistance. Pulmonary vasoconstriction has been proved to play a significant role in PAH. We previously reported that Panax notoginseng saponins (PNS) might attenuate hypoxia and hypercapnia-induced pulmonary vasoconstriction (HHPV). METHODS In the present study, our specific objective was to investigate the role of ginsenoside Rg1, a major component of PNS, in this process and the possible underlying mechanism. The second order pulmonary rings isolated from the Sprague-Dawley rats were treated with different dosage of ginsenoside Rg1 at 8, 40, or 100 mg/L respectively, both before and during the conditions of hypoxia and hypercapnia. Contractile force changes of the rings were detected. Furthermore, SB203580, the selective inhibitor for p38 activation was applied to the rings. Pulmonary arterial smooth muscle cells (PASMCs) were cultured under hypoxic and hypercapnic conditions, and ginsenoside Rg1 was administered to detect the changes induced by p38. RESULTS Under the hypoxic and hypercapnic conditions, we observed a biphasic pulmonary artery contractile response to the second pulmonary artery rings. It is hypothesized that the observed attenuation of vasoconstriction and the production of vasodilation could have been induced by ginsenoside Rg1. This effect was significantly reinforced by SB203580 (P<0.05 or P<0.01). The expression of p38 in the PASMCs under hypoxic and hypercapnic conditions was significantly activated (P<0.05 or P<0.01) and the observed activation was attenuated by ginsenoside Rg1 (P<0.05 or P<0.01). CONCLUSIONS Our findings strongly support the significant role of ginsenoside Rg1 in the inhibition of hypoxia and hypercapnia-induced vasoconstriction by the p38 pathway.

Synergism of Chinese Herbal Medicine: Illustrated by Danshen Compound. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 2016:7279361. [PMID: 27190537 PMCID: PMC4846759 DOI: 10.1155/2016/7279361] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/19/2015] [Revised: 01/05/2016] [Accepted: 02/16/2016] [Indexed: 02/06/2023]
Abstract
The primary therapeutic effects of Chinese herbal medicine (CHM) are based on the properties of each herb and the strategic combination of herbs in formulae. The herbal formulae are constructed according to Chinese medicine theory: the “Traditional Principles for Constructing Chinese Herbal Medicinal Formulae” and the “Principles of Combining Medicinal Substances.” These principles of formulation detail how and why multiple medicinal herbs with different properties are combined together into a single formula. However, the concept of herbal synergism in CHM still remains a mystery due to lack of scientific data and modern assessment methods. The Compound Danshen Formula (CDF) is a validated formula that has been used to treat a variety of diseases for hundreds of years in China and other countries. The CDF will be employed to illustrate the theory and principle of Chinese herbal medicine formulation. The aim of this review is to describe how Chinese herbal medicinal formulae are constructed according to Chinese medicine theory and to illustrate with scientific evidence how Chinese herbs work synergistically within a formula, thereby supporting Chinese medicine theory and practice.

Abstract
OBJECTIVE This study was designed to investigate the effect of Panax notoginseng saponin (PNS) on platelet adhesion to injured endothelial cells (ECs) and platelet activation induced by injured ECs, and to explore its underlying mechanisms. METHODS Human umbilical vein endothelial cells (HUVECs) pretreated with aspirin (ASA,15μg/mL) or PNS (160μg/mL), or neither, were exposed to oxidized low-density lipoprotein (ox-LDL,80mg/L) for 16h. Platelets were then added and co-cultured with HUVECs for 5min. Platelet adhesion to ECs, platelet CD62p expression, and HUVEC apoptosis were assessed by fluorescence activated cell sorting (FACS)·Supernatant concentration of 6-keto-PGF1α and thromboxane 2 (TXB2) were measured by radioimmunoassay. Cyclooxygenase-1 (COX-1) and COX-2 protein expression were measured by western blotting. RESULTS The inhibitory effect of PNS on platelet activation was similar to ASA, but the inhibitory effect of PNS on platelet adhesion to ECs was superior to ASA. PNS modulated COX-2 expression, and increased 6-keto-PGF1α concentration in HUVECs, while down-regulated COX-1 expression and decreased supernatant TXB2 concentration in platelets. Co-culturing of injured HUVECs with platelets increased HUVEC apoptosis induced by ox-LDL compared with HUVECs cultured without platelets; ASA increased HUVEC apoptosis induced by ox-LDL when cultured without platelets, while decreased the apoptosis when co-cultured with platelets. CONCLUSIONS EC protection by ASA is closely associated with its inhibitory effect on platelet activation. PNS is superior to ASA in protecting ECs and in inhibiting platelet adhesion to injured ECs, and the regulation of COX pathway in both ECs and platelets might be the underlying mechanisms of PNS.

Abstract
Traditional Chinese herbal products (CHPs) have been described in ancient medicine systems as treatments for various stroke-associated ailments. This study is aimed to investigate the prescription patterns and combinations of CHPs for ischemic stroke in Taiwan. Prescriptions of CHPs for ischemic stroke were obtained from the National Health Insurance Research Database (NHIRD) of Taiwan. Every prescription with a leading diagnosis of ischemic stroke made during 2000-2010 was analyzed. Descriptive statistics were applied to the pattern of co-prescriptions. Multiple logistic regression models were used to assess demographic and risk factors that are correlated with CHP use. The dataset of inpatient claims data contained information on 15,896 subjects who experienced ischemic stroke from 2000 to 2010. There was an average of 5.82 CHPs in a single prescription for subjects with ischemic stroke. Bu-yang-huan-wu-tang (BYHWT) (40.32%) was by far the most frequently prescribed formula CHP for ischemic stroke, and the most commonly used combination of two-formula-CHP was BYHWT with Shu-jin-huo-xue-tang (SJHXT) (4.40%). Dan Shen (16.50%) was the most commonly used single CHP for ischemic stroke, and the most commonly used combination of two single CHPs was Shi Chang Pua with Yuan Zhi (4.79%). We found that BYHWT and Dan Shen were the most frequently prescribed formula and single CHP for ischemic stroke, respectively. These results provide information about individualized therapy and may contribute to further pharmacologic experiments and clinical trials.

Abstract
Caffeic acid (CA), one of the active constituents of Radix Salvia miltiorrhizae, exhibits antioxidant and anti-inflammatory activities. However, few studies have assessed the ability of CA to inhibit platelet mediated thrombus generation in vivo. In this study, we investigated the antithrombotic effect of CA in mouse cerebral arterioles and venules using intravital microscopy. The antiplatelet activity of CA in ADP stimulated mouse platelets in vitro was also examined in attempt to explore the underlying mechanism. Our results demonstrated that CA (1.25–5 mg/kg) significantly inhibited thrombus formation in vivo. In vitro, CA (25–100 μM) inhibited ADP-induced platelet aggregation, P-selectin expression, ATP release, Ca2+ mobilization, and integrin αIIbβ3 activation. Additionally, CA attenuated p38, ERK, and JNK activation, and enhanced cAMP levels. Taken together, these data provide evidence for the inhibition of CA on platelet-mediated thrombosis in vivo, which is, at least partly, mediated by interference in phosphorylation of ERK, p38, and JNK leading to elevation of cAMP and down-regulation of P-selectin expression and αIIbβ3 activation. These results suggest that CA may have potential for the treatment of aberrant platelet activation-related diseases.

Abstract
Pulmonary arterial hypertension (PAH) is a disease of the small pulmonary arteries characterized by increased vascular resistance. Pulmonary vasoconstriction has been proven to play a pivotal role in PAH. We have previously hypothesized that Panax notoginseng saponins (PNS) might attenuate hypoxia-hypercapnia-induced pulmonary vasoconstriction. The specific objective of the present study was to investigate the role of notoginsenoside R1, a main ingredient of PNS, in this process and the possible underlying mechanism. The third order pulmonary rings from the Sprague-Dawley rats were treated with different concentrations of notoginsenoside R1 (8, 40, and 100 mg/L, respectively) both before and during the conditions of hypercapnia and hypoxia. Contractile force changes in the rings were detected and the optimal concentration (8 mg/L) was selected. Furthermore, an ERK inhibitor, U0126, was applied to the rings. In addition, pulmonary arterial smooth muscle cells (PASMCs) were cultured under hypoxic and hypercapnic conditions, and notoginsenoside R1 was administered to detect the changes induced by ERK1/2. The results revealed biphasic vasoconstriction in rings under hypoxic and hypercapnic conditions. It is hypothesized that the observed attenuation of vasoconstriction and the production of vasodilation could have been induced by notoginsenoside R1. This effect was found to be significantly reinforced by U0126 (p < 0.05 or p < 0.01). ERK expression in the PASMCs under hypoxic and hypercapnic conditions was significantly activated (p < 0.05 or p < 0.01) and the observed activation was attenuated by notoginsenoside R1 (p < 0.05 or p < 0.01). Our findings strongly support the significant role of notoginsenoside R1 in the inhibition of hypoxia-hypercapnia-induced vasoconstriction by the ERK pathway.

Abstract
This open-label, multi-dose, single-center, sequential, inpatient study evaluated the effects of a two herb combination drug (T89, Danshen plus Sanqi) on the steady-state pharmacodynamics (PD) and pharmacokinetics (PK) of warfarin in 24 healthy volunteers. Twenty-three subjects attained a stable international normalized ratio (INR) by taking warfarin alone prior to 1-week of added-on use of T89. INR was not increased after the addition of T89 for 7 days (P > .05). The 90% confidence interval (CI) of the geometric mean ratio for maximum plasma concentrations (Cmax) and area under curve (AUClast ) of both R- and S-warfarin when warfarin was administered with or without T89 was within the 0.80 to 1.25 equivalence ratio. These results indicate that T89 has no effect on the steady-state PD and PK of warfarin. Warfarin and T89 dose adjustments are not required when these two drugs are co-administrated in clinical practice.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Salvianolic acid A (SAA) is one of the main water-soluble components isolated from Salvia miltiorrhiza Bunge. Pharmacological researches revealed that it had various curative activities after oral and intravenous administration, including beneficial effects on diabetes and its complications, cardioprotective effect, anti-platelet aggregation, and so on. However, there is no report regarding the pharmacokinetics of SAA in beagle dogs after oral administration up to now. AIM OF THE STUDY To study the pharmacokinetics of different doses of SAA in beagle dogs and figure out the absolute bioavailability and dose proportionality of SAA after oral administration. MATERIALS AND METHODS Male and female beagle dogs were orally administered SAA 5, 10 and 20mg/kg randomly. The plasma drug concentration was detected by a rapid, sensitive and reproducible liquid chromatography-mass spectrometry (LC-MS) method. The pharmacokinetic parameters were calculated from plasma concentration-time data using the DAS pharmacokinetic software Data Analysis System Version 3.0 program. RESULTS After single-dose oral administration of SAA, the mean peak plasma concentration (Cmax) values for groups treated with 5, 10 and 20 mg/kg doses ranged from 14.38 to 38.18 µg/L, and the mean area under the concentration-time curve (AUC(0-t)) values ranged from 38.77 to 130.33 (µg/L·h). SAA showed lack of dose proportionality over the dose range 5-20mg/kg, based on the power model. However, the increase in systemic exposure with dose appeared linear. The absolute bioavailability was calculated to range from 1.47% to 1.84%. CONCLUSION The pharmacokinetic properties of SAA in beagle dogs after oral administration were characterized as rapid oral absorption, quick clearance, and poor absolute bioavailability. Systemic exposure exhibited lack of dose proportionality over the dose range 5-20mg/kg. Furthermore, a readily preparative LC-MS method was demonstrated in this study for the research of traditional Chinese medicine.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Salvia miltiorrhiza and Panax notoginseng are popularly used traditional Chinese medicine for cardiovascular disorders and they are often used in the form of combination. However, mechanisms of their cardioprotective effects were still not clear. In the present study, the protective effects of salvianolic acids (SA), notoginsengnosides (NG) and combination of SA and NG (CSN) against rat cardiac ischemia-reperfusion injury were checked and the protein expression profiles of heart tissues were examined to search their possible protein targets. MATERIALS AND METHODS The cardioprotective effects of SA, NG and CSN were checked in a rat model of ischemia-reperfusion (IR) by temporarily occluding coronary artery for 20 min followed by reperfusion. Rats were grouped into sham-operation group, IR group, IR+SA group, IR+NG group and IR+CSN group. The plasma creatine kinase (CK) activities were measured using commercial kit and the percentages of infarcted area in total ventricle tissue were calculated after nitroblue-tetrazolium (N-BT) staining of heart tissue slices. Two-dimensional protein electrophoresis (2-DE) was used to check the protein expression profiles of heart tissues. Then, proteins differentially expressed between IR group and sham-operation group were identified using matrix assisted laser desorption ionization-time of flight-mass spectrometry/mass spectrometry (MALDI-TOF MS/MS). The regulative effects of SA, NG and CSN on these IR-related proteins were analyzed. RESULTS Treatments including SA, NG and CSN all showed cardioprotective effects against ischemia-reperfusion injury and CSN exhibited to be the best. Eighteen proteins involved in IR injury were found. These proteins are involved in pathways including energy metabolism, lipid metabolism, muscle contraction, heat shock stress, cell survival and proliferation. The regulation of these proteins by SA, NG or CSN suggested possible protein targets in their cardioprotective effects. CONCLUSIONS SA and NG showed both similarity and difference in their protein targets involved in cardioprotective effects. The capability of CSN to regulate both protein targets of SA and NG might be the basis of CSN to show cardioprotective effects better than that of SA or NG.

Yang S, Zhang K, Lin X, Miao Y, Meng L, Chen W, Tang X. Pharmacokinetic comparisons of single herb extract of Fufang Danshen preparation with different combinations of its constituent herbs in rats. J Pharm Biomed Anal 2012; 67-68:77-85. [PMID: 22579600 DOI: 10.1016/j.jpba.2012.03.058] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2011] [Revised: 03/30/2012] [Accepted: 03/31/2012] [Indexed: 11/16/2022]
Abstract
Salvianolic acid B (SAB), tanshinone IIA (TS), ginsenoside Rb₁ (Rb₁), ginsenoside Rg₁ (Rg₁) and notoginsenoside R₁ (R₁) are major active ingredients of Fufang Danshen preparation (FDP) for its protective effects on myocardial ischemia. This study investigated the pharmacokinetics of marker compounds after oral administration of single herb extract and different combinations of constitutional herbs in FDP, and explored potential herb-herb interactions among the ingredients in the multi-herb medicine. The pharmacokinetics study on the target compounds in rat plasma was performed using an optimal ultra performance liquid chromatography-electrospray ionization tandem mass spectrometry (UPLC-ESI-MS/MS) coupled with protein precipitation method. There were no statistically significant differences in pharmacokinetic parameters of SAB, TS, Rb₁, Rg₁ and R₁ between single Radix Salvia miltiorrhiza (S. miltiorrhiza) or Radix Panax notoginsen (P. notoginseng) extract and combination treatment. While, in comparison with oral administration of P. notoginseng extract alone, the pharmacokinetic parameters (C(max), AUC(0-72 h), AUC(0-∞), Cl, V), particularly for Rb₁ and Rg₁, were significantly different after oral administration P. notoginseng extract with addition of borneol (p<0.05). The AUC(0-72 h) values of Rb₁ and Rg₁ were significantly increased 1.3-fold and 1.6-fold, respectively, after P. Notoginsen extract co-administered with borneol. The results showed that herb-herb interactions may be accounting for the different pharmacokinetic behaviors of active constituents administered in compound prescriptions versus in single-herb extracts, however, which were not significant in most cases.

Abstract
CONTEXT Herbal remedies are used to treat a large variety of diseases, including blood-related disorders. However, a number of herbal preparations have been reported to cause variations in clotting time, this is mainly by disruption of the coagulation cascade. OBJECTIVE The compiling of plants investigated for effects on the coagulation cascade. METHODS Information was withdrawn from Google Scholar and the journal databases Scopus and PubMed. RESULTS Sixty-five herbal remedies were identified with antiplatelet, anticoagulant, or coagulating ability. Bioactive compounds included polyphenols, taxanes, coumarins, saponins, fucoidans, and polysaccharides. CONCLUSION Although research has been conducted on the effect of herbal remedies on coagulation, most information relies on in vitro assays. Contradictory evidence is present on bleeding risks with herbal uses, though herb-drug interactions pose a threat. As the safety of many herbals has not been proven, nor their effect on blood parameters determined, the use of herbal preparations before undergoing any surgical procedure should discontinued.

Abstract
Atherothrombosis, which directly threatens people's health and lives, is the main cause of morbidity and mortality all over the world. Platelets play a key role in the development of acute coronary syndromes (ACSs) and contribute to cardiovascular events. Oral antiplatelet drugs are a milestone in the therapy of cardiovascular atherothrombotic diseases. In recent years, many reports have shown the possibility that “resistance” to oral anti-platelet drugs and many adverse reactions, such as serious bleeding risk, which provides an impetus for developing new anti-platelet drugs possesses highly efficiency and fewer adverse effects. Study on the blood stasis syndrome and promoting blood circulation and removing blood stasis is the most active field of research of integration of traditional and western medicine in China. Blood-stasis syndrome and platelet activation have close relationship, many Chinese herb and formulas for promoting blood circulation and removing blood stasis possess definite anti-platelet effect. This paper covers the progress of anti-platelet mechanism of Chinese herb and formulas for promoting blood circulation and removing blood stasis and is to be deeply discussed in further research.

Differential proteomic analysis of platelets suggested possible signal cascades network in platelets treated with salvianolic acid B. PLoS One 2011; 6:e14692.

Abstract
Background Salvianolic acid B (SB) is an active component isolated from Danshen, a traditional Chinese medicine widely used for the treatment of cardiovascular disorders. Previous study suggested that SB might inhibit adhesion as well as aggregation of platelets by a mechanism involving the integrin α2β1. But, the signal cascades in platelets after SB binding are still not clear. Methodology/Principal Findings In the present study, a differential proteomic analysis (two-dimensional electrophoresis) was conducted to check the protein expression profiles of rat platelets with or without treatment of SB. Proteins altered in level after SB exposure were identified by MALDI-TOF MS/MS. Treatment of SB caused regulation of 20 proteins such as heat shock-related 70 kDa protein 2 (hsp70), LIM domain protein CLP-36, copine I, peroxiredoxin-2, coronin-1 B and cytoplasmic dynein intermediate chain 2C. The regulation of SB on protein levels was confirmed by Western blotting. The signal cascades network induced by SB after its binding with integrin α2β1 was predicted. To certify the predicted network, binding affinity of SB to integrin α2β1 was checked in vitro and ex vivo in platelets. Furthermore, the effects of SB on protein levels of hsp70, coronin-1B and intracellular levels of Ca(2+) and reactive oxygen species (ROS) were checked with or without pre-treatment of platelets using antibody against integrin α2β1. Electron microscopy study confirmed that SB affected cytoskeleton structure of platelets. Conclusions/Significance Integrin α2β1 might be one of the direct target proteins of SB in platelets. The signal cascades network of SB after binding with integrin α2β1 might include regulation of intracellular Ca(2+) level, cytoskeleton-related proteins such as coronin-1B and cytoskeleton structure of platelets.

JOURNAL OF ETHNOPHARMACOLOGY 2011; 133:796-802. [PMID: 21073937 DOI: 10.1016/j.jep.2010.11.008] [Citation(s) in RCA: 44] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2010] [Revised: 11/02/2010] [Accepted: 11/03/2010] [Indexed: 05/30/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE "Dragon's Blood" has been used as a medicine since ancient times by many cultures. In traditional Chinese medicine, the resin obtained from Daemonorops draco (RDD) and the resin from Dracaena cochinchinensis (RDC) are equally prescribed as "Dragon's Blood" for facilitating blood circulation. AIM OF THE STUDY To verify the traditional efficacy and elucidate the mechanism, the present study compared the chemical profiles and the pharmacological effects of two species of "Dragon's Blood" mainly used in China. MATERIALS AND METHODS A UPLC-MS fingerprinting method was developed to compare the chemical profiles of the two medicines. The anti-platelet aggregation effects of the two medicines induced by arachidonic acid (AA) were investigated. RESULTS The chemical profiles of these two species of "Dragon's Blood" were significantly different. The characteristic constituents were found to be: flavanes in RDD and stilbenes in RDC. In the in vivo platelet inhibition test, performed with the dose of 200 mg/kg on rats, the peak inhibitory effects of RDD and RDC were 35.8% and 27.6%, respectively, compared with the control group. With the in vitro concentrations of 0.2, 0.4 and 0.8 mg/ml, RDD exerted significant inhibition of aggregation by 18.7%, 20.0%, and 61.6%, respectively, and RDC exerted significant inhibition of aggregation by 13.3%, 20.2%, and 31.6%, respectively. CONCLUSION The fingerprinting method used here is suitable for distinguishing them. All pharmacological tests indicated that RDD was more potent than RDC against platelet aggregation.

Abstract
BACKGROUND AND OBJECTIVE Salvianolic acid A (SAA) is a water-soluble component from the root of Salvia miltiorrhiza Bunge, a herb that is widely used for atherothrombotic disease treatment in Asian medicine. As platelets play pivotal roles in atherothrombogenesis, we studied the effect of SAA on platelet activation and its underlying mechanisms. METHODS AND RESULTS SAA dose-dependently inhibited platelet aggregation induced by ADP, thrombin, collagen and U46619. It reduced ADP-enhanced platelet P-selectin expression and fibrinogen binding, which consequently hampered ADP-induced platelet-leukocyte aggregation. SAA also inhibited platelet spreading on fibrinogen, a process mediated by outside-in signaling. Under an arterial shear rate of 1000 s(-1), SAA decreased platelet adhesion on collagen surfaces by approximately 40%. Western blot analysis showed that SAA, like the phosphoinositide 3-kinase (PI3K) inhibitors LY294002 and TGX-221, potently inhibited PI3K, as shown by reduced Akt phosphorylation. The in vitro findings were further evaluated in the mouse model of arterial thrombosis, in which SAA prolonged the mesenteric arterial occlusion time in wild-type mice (35 + or - 2 min without SAA and 56 + or - 4 min with SAA; P < 0.01). Interestingly, SAA could even counteract the shortened arterial occlusion time in Ldlr(tm1Her) mutant mice (21 + or - 2 min without SAA and 45 + or - 4 min with SAA; P < 0.01). CONCLUSIONS SAA inhibits platelet activation via the inhibition of PI3K, and attenuates arterial thrombus formation in vivo. Our data suggest that SAA may be developed as a novel therapeutic agent for the prevention of thrombotic disorders.

Abstract
ETHNOPHARMACOLOGICAL SIGNIFICANCE Panax notoginseng (Burk.) F. H. Chen (Araliacea) is traditionally used for its hemostatic and cardiovascular effects when raw and as a tonic when steamed. AIM OF THE STUDY This study aims to compare the effects of raw and steamed Panax notoginseng, Panax ginseng C. A. Meyer and Panax quinquefolium Linn. on platelet aggregation and plasma coagulation. MATERIALS AND METHODS Effects on collagen-induced platelet aggregation were investigated using a platelet aggregometer, while the plasma coagulation times (prothrombin time, activated partial thromboplastin time and thrombin time) were determined using a blood coagulation analyzer. The data was corroborated with ex vivo platelet aggregation and in vivo rat bleeding time. RESULTS Raw and steamed Panax notoginseng significantly inhibit platelet aggregation and plasma coagulation. Steamed Panax notoginseng has significantly more potent antiplatelet and anticoagulant effects than the raw extract, and the antiplatelet and anticoagulant effects increase with increasing steaming durations. Comparing the three common Panax species, Panax notoginseng has higher antiplatelet effect than Panax ginseng and Panax quinquefolium. The in vitro antiplatelet and anticoagulant effects are positively translated into a prolongation of in vivo rat bleeding time after oral administration of the raw and steamed extracts. CONCLUSION The results indicate that the three common Panax species affect platelet aggregation and plasma coagulation differently, with steamed Panax notoginseng showing the greatest antiplatelet and anticoagulant effects. Panax notoginseng may be a good source of lead compounds for novel antiplatelet and anticoagulant therapeutics.

Abstract
Sanqi, the root of Panax notoginseng, is a popularly used traditional Chinese medicine with cardiovascular effects. Notoginsengnosides (NG) isolated from Sanqi could inhibit ADP-induced platelet aggregation of rat washed platelets. To identify the possible target proteins of NG in platelets, two-dimensional gel electrophoresis (2-DE)-based comparative proteomics was performed and proteins altered in expressional level after NG treatment were identified by MALDI-TOF MS/MS. Treatment of 200 microg/ml NG caused regulation of the levels of 12 proteins, which play important roles in platelet activation, oxidative stress and cytoskeleton. In the NG-treated platelets, there were increase in the levels of growth factor receptor-bound protein 2 (Grb2), thrombospondin 1, tubulin alpha 6 and decrease in the levels of thioredoxin, Cu-Zn superoxide dismutase, DJ-1 protein, peroxiredoxin 3, thioredoxin-like protein 2, ribonuclease inhibitor, potassium channel subfamily V member 2, myosin regulatory light chain 9 and laminin receptor 1. The change in the levels of these proteins caused by NG treatment might contribute to the inhibitive effect of NG on platelet aggregation. Furthermore, analysis of the reactive oxygen species (ROS) level indicated that NG could decrease the ROS level in platelets. The regulation of ROS level might play important role in the effect of NG on platelets.
