Abstract
Background Achievement of low-density lipoprotein cholesterol (LDL-C) goal is the most important for the patients with atherosclerotic cardiovascular diseases (ASCVD) who received lipid-lowering therapy. It is unclear that whether combination of ezetimibe with statin is superior to double-dose of statin regarding both of the lipid-lowering efficacy and improvement of inflammation in Chinese patients with ASCVD. Therefore, this study was performed to compare the effects of these two regimes on lipid profiles and inflammation markers. Methods In this randomized control study, ninety eight patients with ASCVD, who were naïve to statins or other lipid-lowering agents, were enrolled into the study, and randomly assigned into two groups, A40 group (atorvastatin 40 mg/d, n = 50), A20E10 group (atorvastatin 20 mg/d combined with ezetimibe 10 mg/d, n = 48).The patients were followed up at week 4 and week 12 after treatment. The lipid profiles and oxidative low-density lipoprotein cholesterol (ox-LDL) were measured at the end of study. Results There were no differences in clinical characteristics including lipid, ox-LDL and hypersensitive C reactive protein (Hs-CRP) among groups at baseline. However, the average level of LDL-C was lower in group A20E10 than that in group A40 significantly (1.59 ± 0.44 mmol/L vs 1.99 ± 0.56 mmol/L, p = 0.001) during follow-up at week 12 after treatment. Importantly, the higher rate of achievement of LDL-C goal was attained at group of combination statin with ezetimibe (79.2% in group A20E10 vs 50.0% in group A40, p = 0.016). The difference of the level of ox-LDL between both the groups after 12 weeks treatment had not statistical significance (3.63 ± 1.13 U/L in group A20E10 vs 4.14 ± 1.32 U/L in group A40, p = 0.077).Similarly, the level of Hs-CRP between both the groups after treatment was not significantly different (p > 0.05). Conclusions In this randomized study, the data showed that a combination of moderate statin and ezetimibe achieved more reduction of LDL-C compared to the double-dose statin but similar impact on inflammation markers.

Abstract
Vascular smooth muscle cell (VSMC) proliferation is a major contributor to atherosclerosis. This study investigated the inhibitory effects of oleanolic acid (OA) against oxidized low-density lipoprotein (ox-LDL)-induced VSMC proliferation in A7r5 cells and explored underlying molecular mechanism. The cell proliferation was quantified with cell counting kit-8 (CCK-8), in which ox-LDL significantly increased A7r5 cells proliferation, while OA pretreatment effectively alleviated such changes without inducing overt cytotoxicity, as indicated by lactate dehydrogenase (LDH) assay. Quantitative real-time RT-PCR (qRT-PCR) and Western blotting revealed increased UCP2 and FGF-2 expression levels as well as decreased p53 and TSP-1 expression levels in A7r5 cells following ox-LDL exposure, while OA pretreatment reversed such changes. Furthermore, inhibiting UCP2 with genipin remarkably reversed the changes in the expression levels of FGF-2, p53, and TSP-1 induced by ox-LDL exposure; silencing FGF-2 with siRNA did not significantly change the expression levels of UCP2 but effectively reversed the changes in the expression levels of p53 and TSP-1, and activation of p53 with PRIMA-1 only significantly affected the changes in the expression levels of TSP-1, but not in UCP2 or FGF-2, suggesting a UCP-2/FGF-2/p53/TSP-1 signaling in A7r5 cells response to ox-LDL exposure. Additionally, co-treatment of OA and genipin exhibited similar effects to the expression levels of UCP2, FGF-2, p53, and TSP-1 as OA or genipin solo treatment in ox-LDL-exposed A7r5 cells, suggesting the involvement of UCP-2/FGF-2/p53/TSP-1 in the mechanism of OA. In conclusion, OA inhibits ox-LDL-induced VSMC proliferation in A7r5 cells, the mechanism involves the changes in UCP-2/FGF-2/p53/TSP-1.

Abstract
ABSTRACT Oxidation of low-density lipoprotein (LDL) has been strongly suggested to play a significant role in the pathogenesis of atherosclerosis. Thus, reducing LDL oxidation is a potential approach to decrease the risk of the atherosclerosis. Organoselenium compounds have demonstrated promising atheroprotective properties in experimental models. Herein, we tested the in vitro atheroprotective capability of a modified organoselenium compound, Compound HBD, in protecting isolated LDL from oxidation as well as foam cells formation. Moreover, the glutathione peroxidase (GPx)-like activity of Compound HBD was analyzed in order to explore the mechanisms related to the above-mentioned protective effects. The Compound HBD in a concentration-dependent manner reduced the Cu2+-induced formation of conjugated dienes. The protein portion from LDL were also protected from Cu2+-induced oxidation. Furthermore, the Compound HBD efficiently decreased the foam cell formation in J774 macrophage cells exposed to oxidized LDL. We found that the atheroprotective effects of this compound can be, at least in part, related to its GPx-like activity. Our findings demonstrated an impressive effect of Compound HBD against LDL-induced toxicity, a further in vivo study to investigate in more detail the antioxidant and antiatherogenic effects of this compound could be considered.
