It has been demonstrated that pitavastatin can significantly reduce low-density lipoprotein (LDL) cholesterol (LDL-C),but its impact on lipoprotein subfractions and oxidized low-density lipoprotein (oxLDL) has not been determined.The aim of the present study was to investigate the potential effects of pitavastatin on subfractions of LDL and high-density lipoprotein(HDL) as well as oxLDL in untreated patients with coronary atherosclerosis (AS).Thirty-six subjects were enrolled in this study.Of them,18 patients with AS were administered pitavastatin 2 mg/day for 8 weeks and 18 healthy subjects without therapy served as controls.The plasma lipid profile,lipoprotein subfractions and circulating oxLDL were determined at baseline and 8 weeks respectively.The results showed that pitavastatin treatment indeed not only decreased LDL-C,total cholesterol (TC),triglycerides (TG) and apolipoprotein B (ApoB) levels,and increased HDL cholesterol (HDL-C),but also reduced the cholesterol concentration of all of the LDL subfractions and the percentage of intermediate and small LDL subfractions.Meanwhile,pitavastatin could decrease plasma oxLDL levels.Furthermore,a more close correlation was found between oxLDL and LDL-C as well as LDL subfractions after pitavastatin treatment.We concluded that a moderate dose of pitavastatin therapy not only decreases LDL-C and oxLDL concentrations but also improves LDL subfractions in patients with AS.

对42CrMo钢进行不同参数下的激光淬火处理,研究了激光淬火功率和扫描速度对42CrMo钢表面淬火硬度和淬火深度的影响规律,分析了在激光功率密度为定值时不同激光淬火参数下硬化性能的变化趋势.研究结果表明,激光功率的增大和扫描速度的减小均可以提高淬火层的深度和硬度;结合激光功率和扫描速度计算所得的能量密度参数与淬火效果存在较强相关性,在能量密度相同时,高功率高速度参数可以增加淬火硬度和深度,并提高加工效率.
