Abstract
Inhibition of vascular smooth muscle cells (VSMCs) proliferation without dysregulating endothelial cells (ECs) may provide an ideal therapy for in-stent restenosis. Due to its anti-proliferation effect on VSMCs and pro-endothelium effect, arsenic trioxide (ATO) has been used in a drug-eluting stent in a recent clinical trial. However, the underlying mechanism by which ATO achieves this effect has not been determined. In the present work, we showed that ATO induced apoptosis in VSMCs but not in ECs. Mechanistically, ATO achieved this through modulation of cellular metabolism to increase lysophosphatidic acid (LPA) in VSMCs, while LPA concentration was stable in ECs. The elevated LPA facilitated the nuclear accumulation and initiated the transcriptional function of Yes-associated protein (YAP) in VSMCs. YAP regulated the transcription of N6-Methyladenosine (m6A) modulators (Mettl14 and Wtap) to increase the m6A methylation levels of apoptosis-related genes to induce their high expression and exacerbate VSMCs apoptosis. On the other hand, YAP nuclear accumulation in ECs was not observed. Collectively, our data exhibited the molecular process involved in selective apoptosis of VSMCs induced by ATO.

Abstract
At present, cardiovascular stent intervention faces clinical complications such as delayed endothelialization, late thrombosis and restenosis after implantation. In this work, a kind of bifunctional polymer brush-grafted coronary stent with anticoagulant and endothelial functions was developed. First, a block copolymer brush with zwitterionic structure consisting of sulfoethyl methacrylate (SBMA) and glycidyl methacrylate (GMA) was surface-induced grafted onto the surface of bare metal coronary stent by atom transfer radical polymerization. The diethylenetriamine NONOate (DETA NONOate), acted as nitric oxide (NO) donor to promote endothelialization, was then attached to polyglycidyl methacrylate (PGMA) brush by a reactive epoxy group to produce NO. The process of chemical modification and the release behavior of NO were characterized in detail. Moreover, the results of anticoagulant test, cytotoxicity test, endothelial cells (ECs) proliferation test and animal experiment of this bifunctional polymer brush-grafted coronary stent we proposed indicate that the zwitterion modified and NO supplied bifunctional coatings has good anticoagulant property, no cytotoxicity and significant endothelialization effect. This work opens the door to combine biological activity of NO and anticoagulant effect of zwitterions, which has great potential to address post-operative side effects associated with restenosis and late stent thrombosis.

Abstract
In the treatment of coronary artery disease (CAD), the use of stent implantation often leads to clinical complications such as restenosis, delayed endothelial healing, and thrombosis. Here, we develop a double drug sustained-release coating for the stent surface by grafting heparin/NONOate nanoparticles (Hep/NONOates). The Hep/NONOates and surface modification of the stent were characterized by X-ray photoelectron spectroscopy, attenuated total reflection Fourier-transform infrared spectroscopy, static water contact angle, and scanning electron microscopy (SEM), and the release behaviors of the anticoagulant, heparin (Hep) and the bioactive molecule, nitric oxide (NO) were studied. Furthermore, the blood compatibility and cytotoxicity of the modified stent were evaluated by whole blood adhesion and platelet adhesion tests, hemolysis assay, morphological changes of red blood cells, plasma recalcification time assay, in vitro coagulation time tests, and MTT assay. Finally, the results of a rabbit carotid artery stent implantation experiment showed that the double drug sustained-release coating for the stent can accelerate regeneration of endothelial cells and keep good anticoagulant activity. This study can provide new design ideas based on nanotechnology for improving the safety and effectiveness of drug-eluting stents.

Abstract
The simultaneous loading of multifunctional drugs has been regarded as one of the major challenges in the drug delivery system. Herein, a mesoporous silica coating was constructed on a bare metal stent surface by an evaporation-induced self-assembly method, in which both hydrophilic and hydrophobic drugs (heparin and rapamycin) were encapsulated by a one-pot method for the first time, and the release behaviors of these drugs were studied. The releasing mechanisms of these drugs were investigated in detail. Rapid release of heparin can achieve anticoagulation and endothelialization, whereas slow release of rapamycin can realize antiproliferative therapy for long term. In vitro hemocompatibility and promotion for proliferation of vein endothelial cells and the inhibition of smooth muscle cells were conducted. In vivo stent implantation results verify that the mesoporous silica coating with both heparin and rapamycin can successfully accelerate the endothelialization process and realize the antiproliferative therapy for as long as 3 months. These results indicate that this multifunctional mesoporous coating containing both hydrophilic and hydrophobic drugs might be a promising stent coating in the future.

Abstract
Currently, nanosecond pulsed electric fields (nsPEFs) with short pulse duration and non-thermal effects have various potential applications in medicine and biology, especially in tumor ablation. Additionally, there are a few investigations on its proliferative effects in the normal cell. Clinically, proliferation of endothelial cells can perhaps accelerate the stent endothelialization and reduce the risk of acute thrombosis. To explore the feasibility using nsPEFs to induce proliferation of endothelial cells, in this study, porcine iliac endothelial (PIEC) cell line was cultured and tested by CCK-8 assay after nsPEFs treatment. The results reflected that nsPEFs with low field strength (100ns, 5 kV/cm, 10 pulses) had a significant proliferative effect with an increase in the PIEC cell growth of 16% after a 48 hour’ post-treatment. To further understand the mechanism of cell proliferation, intracellular Ca2+ concentration was measured through fluo-4 AM and reactive oxygen species assay was applied to estimate the level of intracellular reactive oxygen species (ROS). Finally, the total nitric oxide assay for NO production in the cultured medium was evaluated. An enhanced concentration of intracellular Ca2+ and ROS were observed, while the concentration of extracellular NO also increased after nsPEFs treatment. Such experimental results demonstrated that nsPEFs with appropriate pulse parameters could effectively enhance cell proliferation on PIEC cells, and the cell proliferation associated strongly with the changes of intracellular Ca2+ concertation, ROS and NO production induced by nsPEFs treatment. This in vitro preliminary study indicates that as a novel physical doping, the nsPEFs have potential in stimulating endothelial cells to accelerate stent endothelialization.

Abstract
Coronary heart disease (CHD) is the leading cause of mortality worldwide. Previous studies have suggested that cilostazol-based triple antiplatelet therapy (TAT) may be more effective than conventional dual antiplatelet therapy (DAT) at improving the clinical outcomes of patients with CHD undergoing percutaneous coronary intervention (PCI). However, individually published results are inconclusive. The present meta-analysis evaluated controlled clinical studies to compare the clinical outcomes between TAT and DAT in patients with CHD undergoing PCI. Ten controlled clinical studies were included, with a total of 7,670 patients with CHD undergoing PCI. The total number included 3,925 patients treated with DAT (aspirin and clopidogrel) and 3745 patients treated with TAT (addition of cilostazol to DAT). The crude odds ratio (OR) with a 95% confidence interval (CI) was calculated with either the fixed or random effects model. The meta-analysis results indicated that patients in the TAT group had a significantly lower rate of restenosis compared with that of the DAT group (OR=0.59, 95% CI: 0.45–0.77; P<0.001). The rate of major adverse cardiac events (MACE) and target lesion revascularization (TLR) in the TAT group were significantly lower compared with those in the DAT group (MACE: OR=0.69, 95% CI: 0.56–0.85, P<0.001; TLR: OR=0.61, 95% CI: 0.43–0.88, P=0.008). However, no significant differences between the TAT and DAT groups in terms of mortality rate, myocardial infarction, target vessel revascularization and stent thrombosis were observed. In conclusion, the results of the present meta-analysis indicated that the efficacy and safety of cilostazol-based TAT therapy is greater than that of conventional DAT therapy for patients with CHD undergoing PCI.

Abstract
BACKGROUND Isolated ostial stenosis (IOS) of the left coronary artery is a rare disease of unknown etiology, and the long-term prognosis and angiographic characteristics of affected patients have not been fully studied. METHODS AND RESULTS The present study investigated 57 patients with stenosis of the left main trunk (LMT) who underwent coronary artery bypass grafting (CABG). They were categorized into 3 groups, based on the angiographic findings: Group I comprised 9 patients with IOS; Group II comprised 12 patients with left coronary ostial stenosis in the presence of distal vessel obstructions; Group III comprised 36 patients with stenosis of LMT excluding ostial stenosis and associated with distal vessel obstruction. The patients underwent serial angiography at 1, 5, and 10 years after CABG. Middle aged women with fewer coronary risk factors were more common in Group I compared with Groups II and III (P<0.01). The patency rate of the internal thoracic artery grafts was significantly higher in Groups II and III than in Group I (P<0.05). In Group I, the percentage stenosis of LMT lesions decreased significantly (P<0.05), but there was no difference in the other groups. CONCLUSIONS IOS had clinical characteristics and time course distinct from those of atherosclerotic LMT disease.

The clopidogrel resistance can be attenuated with triple antiplatelet therapy in patients undergoing drug-eluting stents implantation. Int J Cardiol 2008; 134:351-5. [PMID: 18579227 DOI: 10.1016/j.ijcard.2008.02.016] [Citation(s) in RCA: 40] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2007] [Revised: 01/17/2008] [Accepted: 02/14/2008] [Indexed: 11/26/2022]
Abstract
BACKGROUND Triple antiplatelet therapy may have a beneficial effect on prevention of thrombotic complication in patients undergoing coronary stenting. We investigated the prevalence of aspirin and clopidogrel resistance in patients treated with dual and triple antiplatelet regimen after percutaneous coronary intervention (PCI) with drug-eluting stents (DES). METHODS A total of 400 consecutive patients underwent successful PCI with DES were randomly assigned to therapy with dual antiplatelet regimens (aspirin plus clopidogrel, Group I, n = 200) and triple antiplatelet regimens (aspirin plus clopidogrel plus cilostazol, Group II, n = 200) At two weeks after PCI, aspirin and clopidogrel resistance were assayed in 379 patients (Group I, n = 186; Group II, n = 193) by using the VerifyNow System. RESULTS In Group I, 21 (11.3%) patients had aspirin resistance and 74 (40.0%) had clopidogrel resistance. In Group II, 19 (9.8%) were resistant to aspirin and 38 (19.7%) to clopidogrel. The aspirin reaction unit (ARU) was not significantly different between groups (448+/-67 vs. 439+/-64, P = 0.200), but the percent inhibition of clopidogrel was higher in Group II (41.4+/-24.3%,) comparing with that of Group I (26.5+/-18.7%, P < 0.001). CONCLUSION With triple antiplatelet therapy, the prevalence of clopidogrel resistance can be attenuated in patients undergoing PCI with DES.

Abstract
BACKGROUND There is little information about the efficacy of ticlopidine plus aspirin after sirolimus-eluting stent (SES) implantation. METHODS AND RESULTS The incidence of stent thrombosis was evaluated in 1,029 patients receiving ticlopidine and aspirin after SES deployment. Clinical follow-up was obtained in 98.9% (mean follow-up 17.0+/-7.9 months). Early stent thrombosis was observed in 5 patients (0.49%). There was 1 case each of late (0.1%) and very late stent thrombosis (0.1%). CONCLUSION Late and very late stent thrombosis in Japanese patients receiving ticlopidine and aspirin after SES deployment occurs infrequently.
