Abstract
Arterial thrombosis (AT) causes various ischemia-related diseases, which impose a serious medical burden worldwide. As an inhibitor of myosin II, blebbistatin has an important role in thrombosis development. We investigated the effect of blebbistatin on carotid artery ligation (CAL)-induced carotid AT and its potential underlying mechanism. A model of carotid AT in mice was generated by CAL. Mice were divided into three groups: CAL model, blebbistatin-treated, and sham-operation. After 7 days, blood vessels were harvested from mice in each group. The procoagulant activity of tissue factor (TF) was tested by a chromogenic assay, and thrombus severity assessed by histopathology scores. Expression of non-muscle myosin heavy chain II A (NMMHCIIA), TF, glycogen synthase kinase 3β (GSK3β), and nuclear factor-kappa B (NF-κB) was detected by immunohistochemical and immunofluorescence staining. mRNA expression was measured by quantitative polymerase chain reaction. Blebbistatin (1 mg/kg) inhibited development of carotid AT, reduced infiltration of inflammatory cells, and prevented vascular-tissue damage, relative to the model group. Furthermore, blebbistatin also reduced the procoagulant activity of TF. Immunohistochemical and immunofluorescence data demonstrated that, compared with the model group, blebbistatin intervention reduced expression of NMMHCIIA, TF, GSK3β, p65, and p-p65 in carotid-artery endothelia in the CAL-induced AT model, but it increased levels of p-GSK3β. Blebbistatin could inhibit expression of NMMHCIIA mRNA in the CAL model. Overall, our data demonstrated that blebbistatin could inhibit TF expression and AT development in arterial endothelia (at least in part) via GSK3β/NF-κB signaling.

Abstract
In-stent neoatherosclerosis is an important problem after percutaneous coronary intervention. To explore the mechanisms and treatment of in-stent neoatherosclerosis, an animal model is needed. To avoid the disadvantages of current animal models, such as excessive use of X-rays and a high mortality rate, we attempted to develop an improved animal model. We explored a method that uses a short time interval to establish a rabbit model of in-stent neoatherosclerosis with a high survival rate and to evaluate its indicators. Sixty rabbits were divided into three equal groups: group A, the traditional method; group B, the standard intervention method; and group C, the improved method. In group C, we made two small incisions in each rabbit's neck, separated the common carotid, punctured it, and implanted a stent. The incision was then sutured. Four weeks later, we used optical coherence tomography (OCT) to scan all rabbits for neoatherosclerosis. We found no significant differences in OCT data between our new animal model and the traditional and interventional groups (P > 0.05). The technological success rate was higher in the new animal model (P < 0.001). We developed a new method to establish an animal model of neoatherosclerosis, which had similar results to the traditional and interventional methods.

Abstract
This study aims to design an asymmetric dual coating (ADC) on the stent by ultrasonic atomization to solve the problem of delayed endothelialization and late or very late stent thrombosis which caused by drug eluting stent (DES) with symmetric coating. Chitosan-loaded monoclonal platelet glycoprotein IIIa receptor antibody SZ-21 coating (CSC) was sprayed on inner surface of stents, and outer surface was sprayed CSC and poly(lactic-co-glycolic acid) (PLGA) loaded with docetaxel (DTX) coating (PDC). The coated surface was uniform without aggregation and no shedding phenomenon either before or after stent expanded. Fluorescence labeling has confirmed that the coating has an asymmetric structure. The cumulative release for SZ-21 and DTX was 40.11% and 27.22% within first 24 h, then DTX became the major released drug from 24 h to 7 d, after released for 28 d about 40% of the SZ-21 and 50% DTX still remained on the coated stent. It achieved that ADC can inhibit thrombosis at earlier period and inhibit vascular smooth muscle cells (VSMCs) proliferation at later period. And that ADC has good hemocompatibility and can significantly inhibit VSMCs proliferation. Finally, 4 and 12 weeks after the stent with ADC implanted into rabbit carotid arteries, it showed that the stent with ADC was safe and could effectively prevent thrombosis and in-stent restenosis. © 2018 Wiley Periodicals, Inc.
