Abstract
Restenosis after angioplasty is caused usually by neointima formation characterized by aberrant vascular smooth muscle cell (VSMC) dedifferentiation. Myeloid-derived growth factor (MYDGF), secreted from bone marrow-derived monocytes and macrophages, has been found to have cardioprotective effects. In this study we investigated the effect of MYDGF to postinjury neointimal formation and the underlying mechanisms. Rat carotid arteries balloon-injured model was established. We found that plasma MYDGF content and the level of MYDGF in injured arteries were significantly decreased after balloon injury. Local application of exogenous MYDGF (50 μg/mL) around the injured vessel during balloon injury markedly ameliorated the development of neointimal formation evidenced by relieving the narrow endovascular diameter, improving hemodynamics, and reducing collagen deposition. In addition, local application of MYDGF inhibited VSMC dedifferentiation, which was proved by reversing the elevated levels of osteopontin (OPN) protein and decreased levels of α-smooth muscle actin (α-SMA) in the left carotid arteries. We showed that PDGF-BB (30 ng/mL) stimulated VSMC proliferation, migration and dedifferentiation in vitro; pretreatment with MYDGF (50-200 ng/mL) concentration-dependently eliminated PDGF-BB-induced cell proliferation, migration and dedifferentiation. Molecular docking revealed that MYDGF had the potential to bind with sphingosine-1-phosphate receptor 2 (S1PR2), which was confirmed by SPR assay and Co-IP analysis. Pretreatment with CCG-1423 (Rho signaling inhibitor), JTE-013 (S1PR2 antagonist) or Ripasudil (ROCK inhibitor) circumvented the inhibitory effects of MYDGF on VSMC phenotypic switching through inhibiting S1PR2 or its downstream RhoA-actin monomers (G-actin) /actin filaments (F-actin)-MRTF-A signaling. In summary, this study proves that MYDGF relieves neointimal formation of carotid arteries in response to balloon injury in rats, and suppresses VSMC dedifferentiation induced by PDGF-BB via S1PR2-RhoA-G/F-actin-MRTF-A signaling pathway. In addition, our results provide evidence for cross talk between bone marrow and vasculature.

Abstract
BACKGROUND AND OBJECTIVES Abnormal neointimal hyperplasia (NIH) is known as the predominant mechanism in the pathogenesis of arterial restenosis after balloon angioplasty. Low shear stress (SS) is known to augment balloon injury-induced NIH. The aim of this study is to study the effect and mechanisms of an increase of shear stress caused by arteriovenous fistula could alleviate arterial NIH caused by balloon injury. METHODS AND RESULTS Eighteen male rabbits were randomly divided into three groups: BI-the rabbits received a balloon injury to right common carotid artery (CCA). BI+AVF-the rabbits received a balloon injury to right CCA and a carotid-jugular AVF. Control-the animals received no surgery. After 21 days, CCA samples were harvested for histological staining, immunohistochemistry, and western blot analysis. The luminal shear stress of the BI+AVF group increased from 13.8 ± 1.0 dyn/cm2 before surgery to 30.9 ± 1.7 dyn/cm2 right after surgery (p < 0.01). This value was higher than that of the BI or Control groups at any timepoint. The neointimal area and neointima/media area ratio in the BI+AVF group were significantly lower than those in the BI group. In the BI group, the cellular proliferation, the protein levels of yes-associated protein (YAP), connective tissue growth factor (CTGF), phospho-c-Jun N-terminal kinase (pJNK), and vascular cell adhesion protein 1 (VCAM1) increased, whereas the protein levels of SMCs specific genes decreased. In the BI+AVF group, the opposite effect was observed as cellular proliferation and the protein levels of YAP, CTGF, pJNK, and VCAM1 decreased, the protein levels of SMCs specific genes increased. CONCLUSION The arteriovenous fistula alleviated the balloon injury-induced arterial NIH. It elevated the luminal shear stress and inhibited SMCs phenotypic modulation to the synthetic state, as well as suppressing the over-activation of YAP, JNK, and VCAM1.

Abstract
OBJECTIVES Impacts of molecular pathways have been discussed recently on restenosis after percutaneous coronary intervention (PCI). Hence, this study aimed to explore the impact of calcineurin-like phosphoesterase domain containing 1 (CPPED1) and specificity protein 1 (SP1) on restenosis after PCI. METHODS A carotid balloon injury rat model was established, followed by western blot analysis of SP1 and CPPED1 expression in carotid artery (CA) tissues. After SP1 and CPPED1 were overexpressed, the neointimal hyperplasia and luminal stenosis were assessed. In addition, EPC underwent hypoxia/reoxygenation (H/R) treatment to construct an endothelial injury cell model. Then, cell proliferation, apoptosis, intracellular reactive oxygen species (ROS), and Ca2+ concentration were detected with cell counting kit-8 (CCK-8), flow cytometry, Chloromethyl-2'7'-dichlorofluorescein diacetate (CM-H2DCFDA) penetrant, and Fluo-4 AM staining, respectively. The binding relationship between SP1 and CPPED1 was verified by dual-luciferase reporter and chromatin immunoprecipitation (ChIP) assays. RESULTS SP1 and CPPED1 were lowly expressed in the model rats with carotid balloon injury. Mechanistically, SP1 bound to the promoter region of CPPED1 to activate CPPED1 expression. Overexpressing SP1 or CPPED1 lowered neointimal formation and restenosis rate, thus promoting the recovery of carotid balloon injury in rats. Meanwhile, SP1 and CPPED1 upregulation reduced ROS levels, Ca2+ concentration, and apoptosis of EPCs, accompanied by accelerated EPC viability. CONCLUSIONS SP1 or CPPED1 overexpression reduced neointimal formation and restenosis rate in carotid balloon injury.

Abstract
BACKGROUND To investigate the effect and potential molecular mechanisms of Dipsacoside B (DB), an herb monomer extracted from Dipsacusasper or Lonicera macranthoides, on the migration and proliferation of vascular smooth muscle cells (VSMCs) and balloon-induced neointimal formation. METHODS In vivo, rat abdominal aorta balloon injury model was utilized to investigate the effect of DB on the neointimal formation. In vitro, cultured VSMCs were used to investigate the effect of DB on Angiotensin-II (Ang-II)-induced migration and proliferation of VSMCs. Western blot and immunofluorescence were used to measure PTEN expression. RESULTS As compared to vehicle control balloon-injury group, DB treatment significantly inhibited the neointimal formation together up-regulated the expression of phosphatase and tension homolog deleted on chromosome 10 (PTEN). Cell proliferations (MTT and Edu incorporation) assays and wound migration measurement further revealed that treatment with DB significantly blunted Ang-II-induced proliferation and migration potential of VSMCs. Western blot analysis exhibited that DB upregulated the expression of PTEN in vivo and in vitro. CONCLUSIONS DB treatment suppresses the proliferation and migration of VSMCs and reduces neointimal formation by the mechanisms involving regulating the phenotype switch of VSMCs via upregulating PTEN expression.

Abstract
INTRODUCTION Balloon angioplasty is a commonly applied procedure for treating atherosclerotic vascular diseases. However, the maintenance of long-term lumen patency is relatively difficult due to the occurrence of restenosis. Previous research has shown that the occurrence of vascular wall inflammation is associated with higher rates of restenosis. Sophocarpine (SPC) can exert various therapeutic effects such as anti-oxidation, anti-inflammation, anti-tumor, antivirus and immune regulation. This study aimed to investigate whether SPC can alleviate intimal hyperplasia following balloon injury in a rat carotid artery model. METHODS Twenty Sprague-Dawley rats were randomly assigned to four groups: (i) control, (ii) balloon injury, (iii) balloon injury followed by saline injection, and (iv) balloon injury followed by SPC administration. Each group contained five rats. A high-pressure balloon of 3 mm × 20 mm was placed in the carotid artery. The balloon was inflated to a pressure of 8 atmospheres to carry out rat carotid artery balloon injury model. The areas of neointimal and media were determined by Verhoeff_Van Gieson staining, and the intima-to-media (I:M) ratios were subsequently evaluated. After that, the protein levels of IL-6, IL-1β, MCP-1, NF-κB, TNF-α, VCAM-1, ICAM-1 and eNOS were measured. RESULTS The ratio of I:M was remarkably higher in the balloon injury group than in the control group (p < 0.01). SPC could significantly decrease the ratio of I:M compared with the balloon injury group (p < 0.01). Besides, the protein levels of IL-6, IL-1β, MCP-1, NF-κB, TNF-α, ICAM-1 and VCAM-1 were increased in rat carotid arteries exposed to balloon injury (p < 0.01), and treatment with SPC could attenuate these effects (p < 0.05). Furthermore, balloon injury inhibited the protein expression of eNOS (p < 0.01), and SPC could elevate its level (p < 0.05). CONCLUSIONS SPC could alleviate an intimal hyperplasia in balloon-injured carotid artery, and the mechanisms underlying this protective effect might be due to its inhibitory potency against inflammation signals. Our study also implies the potential applicability of SPC in treating restenosis after balloon angioplasty.

Abstract
Valsartan has the potential to attenuate neointimal hyperplasia and to suppress the inflammatory response. This study aimed to evaluate the role of valsartan in neointimal hyperplasia and the toll-like receptor 4 (TLR4)-nitric oxide synthase (NOS) pathway in the balloon-injured rat aorta.Forty-eight Wistar rats were randomly allocated to three groups: sham control (control), balloon-injured group (surgery), and balloon-injured+valsartan-treated group (valsartan). Rats were killed at 14 and 28 days after balloon-injury, and then the aortic tissues were collected for morphometric analysis as well as for measurements of the mRNA or protein expression of angiotensin II, angiotensin II type 1 (AT1) receptor, angiotensin II type 2 (AT2) receptor, TLR4, endothelial nitric oxide synthase (eNOS), inducible NOS (iNOS), serine/arginine-rich splicing factor 1(SRSF1) and extracellular signal regulated kinase (ERK). Valsartan at a dose of 20 mg/kg/day markedly decreased neointimal hyperplasia in the aorta of balloon-injured rats, and significantly reduced the mRNA or protein expression of TLR4, AT1 receptor, SRSF1 and phosphorylated-ERK (p-ERK) as well as the aortic levels of iNOS (all p < 0.05). Moreover, valsartan increased the eNOS level and AT2 receptor mRNA and protein expression levels (all p < 0.05). Valsartan prevented neointimal hyperplasia and inhibited SRSF1 expression and the TLR4-iNOS-ERK-AT1 receptor pathway in the balloon-injured rat aorta.

Abstract
The present study was designed to investigate the therapeutic effects of injection of dihydroartemisinin (DHA) into the balloon-injured carotid arteries on balloon injury-induced neointimal formation and to explore whether autophagy is involved in the action of DHA. Percutaneous transluminal balloon angioplasty was performed in Sprague-Dawley rats to induce neointimal formation, immediately after which DHA (100 μmol/l × 1 ml) and/or Rapamycin (1 mg/100 μl), were injected into the balloon-injured carotid arteries. After 14 days, the serum samples and carotid artery tissues were harvested for analysis. Rat aortic vascular smooth muscle cells (VSMCs) were pretreated with DMSO (vehicle), DHA (1, 10, and 100 μmol/l), or 3-methyladenine (3-MA; 10 mM) for 1 h and then stimulated with platelet-derived growth factor-BB (PDGF-BB; 10 ng/ml) for another 24 h. Animal experiments showed that DHA attenuated the balloon injury-induced neointimal formation, inflammation and VSMC phenotypic transition by inhibiting the balloon injury-induced autophagy activation. In vitro results showed that DHA attenuated the PDGF-BB-induced VSMC phenotypic transition, proliferation, and migration by inhibiting the PDGF-BB-induced autophagy activation. Taken together, DHA ameliorates balloon injury-induced neointimal formation through suppressing autophagy. This study provides insights into the development of a drug-eluting stent using DHA.

Abstract
Vascular remodeling (VR), induced by the massive proliferation and reduced apoptosis of vascular smooth muscle cells (VSMCs), is primarily responsible for many cardiovascular conditions, such as restenosis and pulmonary arterial hypertension. Sodium selenite (SSE) is an inorganic selenium, which can block proliferation and stimulate apoptosis of tumor cells; still, its protective effects on VR remains unknown. In this study, we established rat models with carotid artery balloon injury and monocrotaline induced pulmonary arterial hypertension and administered them SSE (0.25, 0.5, or 1 mg/kg/day) orally by feeding tube for 14 consecutive days. We found that SSE treatment greatly ameliorated the development of VR as evidenced by an improvement of its characteristic features, including elevation of the ratio of carotid artery intimal area to medial area, right ventricular hypertrophy, pulmonary arterial wall hypertrophy and right ventricular systolic pressure. Furthermore, PCNA and TUNEL staining of the arteries showed that SSE suppressed proliferation and enhanced apoptosis of VSMCs in both models. Compared with the untreated VR rats, lower expression of PCNA and CyclinD1, but higher levels of Cleaved Caspase-3 and Bax/Bcl-2 were observed in the SSE-treated rats. Moreover, the increased protein expression of MMP2, MMP9, p-AKT, p-ERK, p-GSK3β and β-catenin that occurred in the VR rats were significantly inhibited by SSE. Collectively, treatment with SSE remarkably attenuates the pathogenesis of VR, and this protection may be associated with the inhibition of AKT and ERK signaling and prevention of VSMC’s dysfunction. Our study suggest that SSE is a potential agent for treatment of VR-related diseases.

Abstract
Introduction The main pathological mechanism of restenosis after percutaneous coronary intervention (PCI) is intimal hyperplasia, which is mainly caused by proliferation and migration of vascular smooth muscle cells (VSMCs). Our previous study found that honokiol (HNK), a small-molecule polyphenol, can inhibit neointimal hyperplasia after balloon injury, but its specific mechanism is still unclear. Moreover, poor water solubility as well as low bioavailability of honokiol has limited its practical use. Methods We used mesoporous silica nanoparticles (MSNPs) as a standard substance to encapsulate HNK and then assemble into honokiol-mesoporous silica nanoparticles, and we investigated the effect of these nanoparticles on the process of restenosis after common carotid artery injury in rats. Results We report a promising delivery system that loads HNK into MSNPs and finally assembles it into a nanocomposite particle. These HNK-MSNPs not merely inhibited proliferation and migration of VSMCs by reducing phosphorylation of Smad3, but also showed a higher suppression of intimal thickening than the free-honokiol-treated group in a rat model of balloon injury. Conclusion To sum up, this drug delivery system supplies a potent nano-platform for improving the biological effects of HNK and provides a promising strategy for preventing vascular restenosis.

Abstract
INTRODUCTION Oral statins reduce intimal hyperplasia (IH) after arterial injury by only ∼25%. Alternative drug delivery systems have gained attention as carriers for hydrophobic drugs. We studied the effects of simvastatin (free vs hyaluronic acid-tagged polysialic acid-polycaprolactone micelles) on vascular smooth muscle cell (VSMC) migration, VSMC proliferation and intimal hyperplasia. We hypothesized both free and micelle containing simvastatin would inhibit VSMC chemotaxis and proliferation, and local statin treatment would be more effective than oral in reducing IH in rats following carotid balloon injury. METHODS VSMCs pretreated with free simvastatin (20 minutes or 20 hours) or simvastatin-loaded micelles underwent chemotaxis and proliferation to platelet-derived growth factor. Next, rats that underwent balloon injury of the common carotid artery received statin therapy-intraluminal simvastatin-loaded micelles prior to injury, periadventitial pluronic gel following injury, or combinations of gel, micelle, and oral simvastatin. After 14 days, morphometric analysis determined the -intimal to medial ratio. Findings were compared to controls receiving oral simvastatin or no statin therapy. Statistical analysis was by analysis of variance for the in vitro experiments and a factorial general linear model for the in vivo experiments. RESULTS The simvastatin-loaded micelles and free simvastatin inhibited VSMC chemotaxis (54%-60%). IH was induced in all injured vessels. Simvastatin in pluronic gel or micelles reduced IH compared to untreated controls (0.208 ± 0.04 or 0.160 ± 0.03 vs 0.350 ± 0.03, respectively); however, neither gel nor simvastatin-loaded micelles were superior to oral statins (0.261 ± 0.03). Addition of oral statins or combining both local therapies did not provide additional benefit. Micelles were the single greatest contributing factor in IH attenuation. CONCLUSIONS Intraluminally or topically delivered statins reduced IH. The efficacy of single-dose, locally delivered statin alone may lead to novel treatments to prevent IH. The different routes of administration may allow for treatment during endovascular procedures, without the need for systemic therapy.

Abstract
Objective Chronic stress may lead to augmented incidence rates of coronary and
cerebrovascular diseases associated with atherosclerosis. However, few
studies have focused on the effect of chronic stress on atherosclerosis
plaque formation. Therefore, this study was designed to directly evaluate
how chronic stress affects atherosclerosis. Methods Thirty rabbits were divided into three groups: the control group,
balloon-injury operation + high-fat diet model group, and chronic
stress + balloon-injury operation + high-fat diet model group. Physical and
social stress were induced, and proteomic methods were applied to identify
specific markers. Results After protein determination, the chronic stress + balloon-injury
operation + high-fat diet model group exhibited significant upregulation of
the following apoptosis-related proteins: UBE2K, caspase 3, caspase 9, BAX,
P53, and FAS. In particular, real-time polymerase chain reaction showed that
the protein expression of caspase 9 was significantly downregulated in the
stress group compared with the non-stress groups. However, the other
proteins showed significantly increased expression in the stress group. Conclusion Chronic stress may promote cell apoptosis in the physiopathologic process of
atherosclerosis.

Abstract
Percutaneous coronary intervention (PCI) is main treatment for acute coronary syndrome
(ACS). However, restenosis caused by PCI-induced injury influences the outcome of
patients. Linagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, has been reported to
ameliorate intimal hyperplasia post vascular injury. The underlying mechanisms by which
linagliptin protects against balloon injury are unclear and require to be explored.
Herein, Wistar rats with carotid artery balloon injury were given 1, 2 or 3 mg/kg/day
linagliprin for 6 weeks. We found that linagliptin attenuated vascular injury-mediated
neointima formation in rats without affecting body weight and blood glucose levels. ELISA
results indicated that linagliptin significantly reduced overproduction of cytokines
including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-6 post balloon
injury. By detecting the level of malondialdehyde (MDA) and the activities of superoxide
dismutase (SOD) and glutathione peroxidase (GSH-Px), we found that linagliptin prevented
balloon injury-induced oxidative stress. Additionally, linagliptin decreased the level of
Kelch ECH-associating protein 1 (KEAP1) compared with injury group. Results of Western
blots and electrophoretic mobility shift assay (EMSA) demonstrated that linagliptin
augmented nuclear accumulation of nuclear factor-E2-related factor 2 (NRF2) and its
binding ability to target genes in rats with balloon injury. Moreover, heme oxygenase-1
(HO-1) and NAD (P) H quinine oxidoreductase 1 (NQO1), two downstream targets of NRF2, were
further up-regulated after linagliptin treatment compared with injury group. In
conclusion, our data suggest that linagliptin protects carotid artery from balloon
injury-induced neointima formation and activates the NRF2 antioxidant pathway.

Abstract
Percutaneous coronary intervention (PCI) is used commonly for coronary artery disease (CAD); however, restenosis is a proliferative response and frequent sequela to this treatment. Although the introduction of drug-eluting stents has convincingly reduced the incidence of vascular restenosis, restenosis remains a problem. The present study was designed to investigate the effects of the heme oxygenase-1 (HO-1) on restenosis formation after balloon injury in a rabbit carotid artery model. We found that involvement of the HO-1 in defensive restenosis formation was independent of the levels of blood lipid. Activation of HO-1 induced by chlorhematin treatment alleviated vascular restenosis after balloon injury in a rabbit carotid artery model, whereas inhibition of HO-1 by zinc protoporphyrin treatment exacerbated restenosis formation. Furthermore, overexpression of HO-1 inhibited nuclear factor kappa B subunit 1 (NF-кB) activity and decreased tumor necrosis factor-alpha (TNF-α) and endothelin 1 (ET-1) expression. In conclusion, our study provides preliminary data suggesting that HO-1 alleviates vascular restenosis after balloon injury in a rabbit carotid artery model by inhibiting NF-кB, TNF-α and ET-1 expression, indicating induction of HO-1 activation may be a feasible therapeutic target for treating vessels resistant to restenosis.

Abstract
Hepatic growth factor (HGF) has been widely used in studies on arterial remodeling after injury, and results turn out to be inconsistent. The changes of endogenous HGF expression after injury also remain controversial. This study clarified the role of exogenous human HGF (hHGF) gene transfer in neointimal hyperplasia and investigated the associated alterations of endogenous HGF and c-Met expressions under endothelial denudation with or without hHGF gene transfer using a balloon-injured rabbit aorta model. Sixty-one rabbits were randomly divided into normal controls, endothelial injury, endothelial injury with hHGF, or the control vector gene transfer groups. On weeks 1, 2, 4, and 8 after injury, neointimal hyperplasia and endothelialization were evaluated by the ratio of neointimal area to medial area (N/M ratio), CD31-positive staining, α-smooth muscle actin, and endothelial nitric oxide synthase expressions using histological analysis, immunohistochemistry staining, or real-time quantitative reverse transcriptase polymerase chain reaction. Endogenous rabbit HGF (rHGF) and c-Met expressions were detected with immunohistochemistry staining and quantitative reverse transcriptase polymerase chain reaction. It was found that expressions of endogeneous rHGF and c-Met in endothelial injury upregulated with peak levels on week 2 or week 4 after injury (p < 0.01). On week 1 after hHGF transfer, neointimal hyperplasia was significantly inhibited (p < 0.001), with decreased α-smooth muscle actin expression (p < 0.05) and improved endothelial cells regeneration and function (p < 0.01). More remarkable overexpression of endogenous rHGF and c-Met mRNAs were detected, and lowered positive staining of rHGF and c-Met was shown in the neointima (p < 0.05). These results demonstrated hHGF gene transfer induced further overexpression of endogenous rHGF and c-Met mRNAs but lowered immunoreactivities of rHGF and c-Met in the neointima, thus leading to significant attenuation of neointimal hyperplasia.

Abstract
Disruption of endothelial cell function is a principle event in cardiovascular disease. Accordingly, therapies have mostly focused on repairing the endothelium, but little attention has been paid to the reconstruction of glycocalyx, which covers the endothelium and protects the function of endothelial cells. Sulodexide has a similar glycosaminoglycan structure to glycocalyx, so it is assumed to be effective in remodeling the glycocalyx following damage. We assessed the effect of sulodexide on glycocalyx remodeling and endothelial function in the balloon-injury rat carotid artery model. Electron micrographs showed that sulodexide (2mg/kg, administered by intraperitoneal injection for seven days after injury) could reconstruct the endothelial glycocalyx and recover the clear cytoarchitecture. With regard to endothelial function, sulodexide increased endothelial nitric oxide synthase level, attenuated endothelial hyperplasia, and inhibited platelet aggregation that benefitted from glycocalyx reforming. Sulodexide decreased the glycocalyx damage related expression of CD31 and intercellular cell adhesion molecule-1 in endothelium, accompanying by the downregulation of leukocyte counts and C-reactive protein levels. The levels of the atherosclerosis-related factors, osteopontin and vascular cell adhesion molecule-1, which increased in activated endothelial cells lacking glycocalyx, were normalized by sulodexide. Along with the benefit of glycocalyx reconstruction, sulodexide reversed the dyslipidemia. Moreover, sulodexide prevented CD68-positive inflammatory cells infiltration into the vascular wall, presumably as a result of glycocalyx reconstruction. In summary, sulodexide treatment reconstructed glycocalyx which therefore preserved endothelial function and attenuated the expression of inflammatory factors, and decreased the blood coagulation and lipid metabolism, all of which are important for vascular healing.

Abstract
PURPOSE Appropriate animal models of atherosclerotic plaque are crucial to investigating the pathophysiology of atherosclerosis, as well as for the evaluation of the efficacy and safety of vascular devices. We aimed to develop a novel animal model that would be suitable for the study of advanced atherosclerotic lesions in vivo. MATERIALS AND METHODS Atherosclerotic plaque was induced in 24 iliac arteries from 12 rabbits by combining a high cholesterol diet, endothelial denudation, and injection into the vessel wall with either saline (n=5), olive oil (n=6), or inflammatory proteins [n=13, high-mobility group protein B1 (HMGB1) n=8 and tumor necrosis factor (TNF)-α n=5] using a Cricket™ Micro-infusion catheter. Optical coherence tomography (OCT) was performed to detect plaque characteristics after 4 weeks, and all tissues were harvested for histological evaluation. RESULTS Advanced plaque was more frequently observed in the group injected with inflammatory proteins. Macrophage infiltration was present to a higher degree in the HMGB1 and TNF-α groups, compared to the oil or saline group (82.1±5.1% and 94.6±2.2% compared to 49.6±14.0% and 46.5±9.6%, p-value<0.001), using RAM11 antibody staining. On OCT, lipid rich plaques were more frequently detected in the inflammatory protein group [saline group: 2/5 (40%), oil group: 3/5 (50%), HMGB1 group: 6/8 (75%), and TNF-α group: 5/5 (100%)]. CONCLUSION These data indicate that this rabbit model of atherosclerotic lesion formation via direct injection of pro-inflammatory proteins into the vessel wall is useful for in vivo studies investigating atherosclerosis.

Abstract
Neointimal hyperplasia is the leading cause of restenosis after endovascular interventions. It is characterized by the accumulation of myofibroblast-like cells and extracellular matrix in the innermost layer of the wall and is exacerbated by inflammation. Monocytes from either young or aged rats were applied perivascularly to injured vascular walls of young recipient animals. Monocytes from aged rats, but not young donors, increased neointima thickness. Accordingly, the gene expression profiles of CD11b+ monocytes from aged rats showed significant up-regulation of genes involved in cellular adhesion, lipid degradation, cytotoxicity, differentiation, and inflammation. These included cadherin 13 (Cdh13), colony stimulating factor 1 (Csf1), chemokine C-X-C motif ligand 1 (Cxcl1), endothelial cell-selective adhesion molecule (Esam), and interferon gamma (Ifng). In conclusion, our results suggest that the increased inflammatory and adhesive profile of monocytes contributes to pathological wall remodeling in aged-related vascular diseases.

Abstract
This study is to investigate the effects of high mobility group box 1 (HMGB-1) and nuclear factor κB (NF-κB) on intimal hyperplasia after carotid artery balloon injury. A total of 28 male SD rats were subjected to balloon catheter injury at left side carotid artery and this side was considered as experimental group. The right side was taken as control group. Common carotid arteries were harvested at 6 h, 3 d, 7 d and 14 d after balloon injury. The intimal thickness and lumen area were analyzed by HE staining and computerized method. HMGB-1 expression was tested by RT-PCR and NF-κB was detected by EMSA. Among the 28 rats, 4 were excluded due to failed modeling or death and the other 24 rats were included for analysis. Carotid endarterectomy, intimal hyperplasia and restenosis were found after balloon injury. Intimal hyperplasia appeared on 3 d and was significant on 14 d after injury. The ratio of intima/media in the experimental group increased significantly compared with the control group (P < 0.05). HMGB-1 was scarcely expressed in control group. It increased 6 h and peaked on 14 d after injury, with significant difference compared with the control group (P < 0.01). Similarly to HMGB-1, NF-κB was rarely expressed in control group, and its level increased since 6 h and peaked on 14 d after injury. Intimal hyperplasia after carotid artery balloon injury was found in rat model and this might be induced by enhanced expression of HMGB-1 and NF-κB.

Abstract
In-stent restenosis (ISR) is one of the major factors affecting long-term outcomes of percutaneous coronary interventions. Vascular endothelial growth factor (VEGF) has been hypothesized to have a positive role in preventing ISR, however, this remains controversial. The aim of the present study was to assess whether nanoparticles can be used to deliver VEGF to injured arteries and whether this is beneficial in preventing restenosis. New Zealand White rabbits were randomly divided into a control group, an empty nanoparticles group and a VEGF nanoparticles group (n=6 in each group). Polylactic-polyglycolic acid VEGF nanoparticles were prepared using a phacoemulsification method. A rabbit model of restenosis was established following abdominal aorta balloon injury, and VEGF gene nanoparticles, empty nanoparticles or normal saline were delivered locally at the site of injury via a GENIE Catheter™ perfusion balloon. Intimal proliferation determination and immunohistochemistry analysis were performed at day 28 following arterial injury. Compared with the control and empty nanoparticle groups, the neointima area (0.49±0.09, 0.48±0.08 and 0.19±0.11 mm2, respectively; P<0.001) and proliferation index (0.32±0.03, 0.32±0.05 and 0.13±0.06, respectively; P<0.001) were significantly lower in the VEGF nanoparticles group. In addition, in the VEGF nanoparticles group, the immunoreactivity of α-actin and proliferating cell nuclear antigen were significantly lower (P≤0.001), while the immunoreactivity of VEGF was higher (P=0.01). Therefore, the results revealed that local delivery of VEGF gene nanoparticles reduced intimal thickening and cell proliferation following abdominal aorta balloon injury in a rabbit model, demonstrating the efficacy of this therapy against restenosis.

Abstract
OBJECTIVE To study the effect of valsartan on ACAT-1 and PPAR-γ expression after vascular endothelial balloon injury in intimal hyperplasia process. METHODS 24 male New Zealand white rabbits were randomly divided into three groups with 8 in each group. CONTROL GROUP rabbits were fed with normal diet; Balloon injury group: rabbits were fed with 0.5% cholesterol, 5% lard rabbit feed; balloon injury + valsartan group, rabbits were fed with 0.5% cholesterol, 5% lard rabbit feed added with 10 mg/(kg.d) valsartan gavage. RT-PCR and Western blotting method were used to detect the carotid ACAT-1, PPAR-γ mRNA and protein expression after 8 weeks of feeding. RESULTS In carotid artery balloon injury group, vascular smooth muscle cells (VSMC) proliferation and intimal hyperplasia were significantly higher 14 d after endothelial injury. In 14 days valsartan treatment group VSMC proliferation and intimal hyperplasia were lighter than the surgery group. Compared with the control group, ACAT-1, PPAR-γ mRNA and protein were significantly increased in balloon injury group and valsartan group (P < 0.01 or P < 0.05); the expression of ACAT-1 mRNA and protein were significantly lower in valsartan group and balloon injury group (P < 0.01 or P < 0.05). The expression of PPAR-γ mRNA and protein in valsartan group expression was significantly higher than that in the balloon injury group (P < 0.05). The expression level of ACAT-1 and PPAR-γ mRNA in balloon injury group and valsartan group showed negative correlation (P < 0.05). CONCLUSION The expression of ACAT-1, PPAR-γ mRNA and protein content were significantly increased in intimal hyperplasia process after vascular endothelial balloon injury. The effect of valsartan suppressed intimal hyperplasia correlated with the expression of down-regulated ACAT-1 and up-regulated PPAR-γ.

Abstract
BACKGROUND Celastrol may have an anti-atherosclerosis effect. This study aimed to investigate if celastrol had an anti-AS effect using a rabbit experimental carotid atherosclerosis model. METHODS Forty male Japanese white rabbits were divided into the sham group (normal diet), the model group (high fat diet), the group treated with celastrol (high fat diet) and the group treated with atorvastatin (high fat diet) randomly. The rabbits fed a high fat diet underwent balloon injury of the right common carotid artery and were treated with dimethyl sulfoxide (DMSO) (the model group, 3.5 ml/kg/d), celastrol and its dissolvent DMSO (the celastrol group, 1 mg/kg/d and 3.5 ml/kg/d) and atorvastatin and its dissolvent DMSO (the atorvastatin group, 2.5 mg/kg/d and 3.5 ml/kg/d) for 12 weeks by gavage. RESULTS The ratio of the plaque area and the arterial wall cross-section area in the celastrol group was significantly less than the model group (P < 0.001), and there was no significant difference compared with the atorvastatin group. The serum level of LDL-C of the celastrol group was significantly lower than the model group (P = 0.014), and there was no significant difference compared with the atorvastatin group. The expression of VEGF in the celastrol group was significantly less compared with the model group (P = 0.014), whereas the expression of VEGF in the atorvastatin group and the model group showed no significant differences. CONCLUSION Our findings suggest that celastrol effectively reduced the plaque ratio, decreased the serum levels of LDL and downregulated the expression of VEGF, suggesting an anti-AS effect of celastrol.

Abstract
Transforming growth factor (TGF)-β1 has been suggested to be involved in the recruitment of mesenchymal stem cells (MSCs) following arterial injury, but the role of downstream signaling and the contribution of the recruited MSCs are still unknown. The release of latent TGF-β1 from latent TGF-binding protein (LTBP) by matrix metallopeptidase-14 (MMP-14) proteolysis was demonstrated, which contributed to neointima formation, but the relationship between MMP-14 and activated TGF-β1 in the process of restenosis has yet to be explored. In this study, we observed the change in expression and distribution of TGF-β1/Smad signaling pathway proteins, MMP-14, and MSC markers in the process of neointima formation using a rat model for balloon-induced carotid artery injury. We found that the increase in downstream Smad signaling was consistent with the elevation of TGF-β1 levels and MSCs accumulated at the lumen side of neointima. Furthermore, the activation of MMP-14 in the injured artery was preceded by the increase in TGF-β1 levels. Herein, we conclude that MMP-14 induces an elevation in the levels of TGF-β1/Smad signaling proteins in injured arteries, and that MSCs are recruited by TGF-β1/Smad signaling and MMP-14, possibly differentiating into vascular smooth muscle cell (VSMC)-like cells and VSMC via modulation of TGF-β1/Smads signaling and MMP-14.

Abstract
In cardiovascular research, translation of benchtop findings to the whole body environment is often critical in order to gain a more thorough and comprehensive clinical evaluation of the data with direct extrapolation to the human condition. In particular, developmental and/or pathophysiologic vascular growth studies often employ in vitro approaches such as cultured cells or tissue explant models in order to analyze specific cellular, molecular, genetic and/or biochemical signaling factors under pristine controlled conditions. However, validation of in vitro data in a whole body setting complete with neural, endocrine and other systemic contributions provides essential proof-of-concept from a clinical perspective. Several well-characterized experimental in vivo models exist that provide excellent proof-of-concept tools with which to examine vascular growth and remodeling in the whole body. This article will examine the rat carotid artery balloon injury model, the mouse carotid artery wire denudation injury model, and rat and mouse carotid artery ligation models with particular emphasis on minimally invasive surgical access to the site of intervention. Discussion will include key scientific and technical details as well as caveats, limitations, and considerations for practical use for each of these valuable experimental models.

Abstract
BACKGROUND Arterial remodeling occurs as a response to hemodynamic change and direct vessel wall injury through the process of neointimal hyperplasia (NH). A concomitant response of vascular smooth muscle cell (VSMC) proliferation and apoptosis exists. The purpose of this study is to assess the cellular response of vessels following exposure to low shear stress (tau) and balloon injury in order to further elucidate the mechanisms underlying vascular injury. Our hypothesis is that the combination of low tau and balloon injury results in NH approximating that seen in clinical arterial restenosis, and that quantitative analysis of VSMC proliferation and apoptosis correlates with the associated increase in arterial remodeling. METHODS AND RESULTS New Zealand White rabbits underwent surgery on the carotid artery creating low tau (n =11), balloon injury (n = 11), combined low tau and balloon injury (n =11), and sham (n = 13) groups. Experiments were terminated at 1, 3, and 28 d. Day 1 and 3 arteries were analyzed with immunohistochemistry for apoptotic markers, terminal transferase dUTP nick end labeling (TUNEL), and activated caspase-3, and a cellular proliferation marker, accumulated proliferating cell nuclear antigen (PCNA), as well as immunoblot analysis for activated caspase-3 and PCNA at day 3. There was significantly greater apoptosis in the combined group as compared with the other groups assessed by quantitative TUNEL and activated caspase-3 levels at both days 1 and 3. Similarly, an increase in cellular proliferation assessed by PCNA expression, was significantly greater in the combined group as compared with the other groups. At 28 d there was no difference in NH observed in the low tau (26 +/- 3 microm) and balloon injury (51 +/- 17 microm) groups. However, significantly more NH was observed in the combined group (151 +/- 35 microm) as compared with the other groups. CONCLUSIONS An increase in VSMC apoptosis via a caspase-3 dependent pathway is up-regulated by 24 h in the face of combined low shear stress and balloon-induced vessel wall injury. Paradoxically, this increase in VSMC apoptosis is associated with a significant increase in neointimal thickening at 28 d. The concomitant increase of both apoptosis and proliferation are indicative of a robust arterial remodeling response.

Abstract
Recent studies indicate that systemic induction of heme oxygenase-1 (HO-1), which oxidatively degrades heme into iron, biliverdin, and carbon monoxide (CO), or adenoviral-mediated gene transfer of HO-1 inhibits neointima formation after experimental vascular injury. In the present study, we investigated whether the acute, local administration of the HO-1 product, CO, regulates the arterial remodeling response following injury. Immediately after balloon injury of rat carotid arteries, a saturated solution of CO or nitrogen (N2), or phosphate buffered saline (PBS) was incubated luminally within the injured vessels for 30 min. Two weeks after injury, arteries exposed to CO exhibited significantly reduced neointimal area, neointimal area/medial wall area ratio, neointimal thickness, and medial wall area compared to arteries exposed to N2 or PBS. Arteries exposed to CO also demonstrated significantly reduced DNA synthesis in the medial wall two days after injury as suggested by proliferating cell nuclear antigen immunostaining, and this was associated with a decrease in the protein expression of the G1 cyclins, cyclin E and A, and transforming growth factor-beta1. These results indicate that the acute, local delivery of CO blocks the pathophysiological remodeling response to vascular injury, and identifies CO as a potentially important therapeutic agent in the treatment of vasculoproliferative disease.

Abstract
BACKGROUND Balloon injury (BI) of the rat carotid artery (CCA) is widely used to study intimal hyperplasia (IH) and decrease in lumen diameter (LD), but CCA's small diameter impedes the evaluation of endovascular therapies. Therefore, we validated BI in the aorta (AA) and iliac artery (CIA) to compare it with CCA. METHODS Rats underwent BI or a sham procedure (control). Light microscopic evaluation was performed either directly or at 1, 2, 3, 4 and 16 weeks follow-up. The area of IH and the change in LD (LD at 16 weeks minus LD post BI) were compared. RESULTS In the BI-groups the area of IH increased to 0.14 +/- 0.08 mm2 (CCA), 0.14 +/- 0.03 mm2 (CIA) and 0.12 +/- 0.04 mm2 (AA) at 16 weeks (NS). The LD decreased with 0.49 +/- 0.07 mm (CCA), compared to 0.22 +/- 0.07 mm (CIA) and 0.07 +/- 0.10 mm (AA) at 16 weeks (p < 0.05). The constrictive vascular remodelling (CVR = wall circumference loss combined with a decrease in LD) was -0.17 +/- 0.05 mm in CIA but absent in CCA and AA. No IH, no decrease in LD and no CVR was seen in the control groups. CONCLUSIONS BI resulted in: (1.) a decrease in LD in CCA due to IH, (2.) a decrease in LD in CIA due to IH and CVR, (3.) no change in LD in AA, (4.) Comparable IH development in all arteries, (5.) CCA has no vasa vasorum compared to CIA and AA, (6.) The CIA model combines good access for 2 F endovascular catheters with a decrease in LD due to IH and CVR after BI.

Abstract
1. The aim of this study was to examine the changes in leukocyte adhesion and leukocyte-induced contraction in balloon-injured rabbit subclavian artery and to correlate these changes with vessel morphology and expression of adhesion molecules on the injured arteries. 2. Rabbits were anaesthetized and their left subclavian arteries were injured by balloon inflation and withdrawal followed by sacrifice at 2, 24, 48 h or 8 days after injury. The left and right subclavian arteries were removed and leukocytes were isolated from autologous rabbit blood. Leukocyte-induced contraction was measured in 5-HT precontracted artery rings and leukocyte adhesion was measured using (51)Cr-labelled leukocytes. Immunocytochemistry using paraffin-embedded tissue was employed to detect changes in the expression of adhesion molecules on injured arteries. 3. Autologous leukocytes caused a contraction of rabbit subclavian artery rings, which was prevented by L-NAME (10(-3) M). Balloon-induced injury abolished the contractile response to leukocytes, which correlated with loss of carbachol-induced relaxation 4. Balloon injury markedly enhanced the adhesiveness of the subclavian artery for leukocytes, most notably at 24 and 48 h after injury (1.7 and 1.8 fold respectively). Increased leukocyte adhesion at these two time points correlated with an upregulation of E-selectin, P-selectin and VCAM-1 expression on the remaining endothelium of the injured artery. 5. Vessel morphology revealed that balloon inflation had induced an infiltration of inflammatory cells into the vessel wall, the greatest increase being seen at 24 h after injury. 6. It is concluded that an increase in the expression of E-selectin, P-selectin and VCAM-1 following balloon-induced injury leads to enhanced leukocyte adhesion and migration into the injured vessel.
