Objectives
Narrative objectives1 The endothelium is one of the most important targets of cardiovascular risk factors including hypertension, dyslipidemia, and diabetes mellitus. Endothelial dysfunction is not only the initial step of atherosclerosis, leading to systemic vascular damage, but also a novel predictor of cardiovascular events. Sphingosine 1-phosphate (S1P) is a potent bioactive lipid responsible for vascular cell protection in vitro. The present study was designed to investigate (1) relationship of S1P with endothelial function and cardiovascular risk factors and (2) effects of medical treatments on S1P, endothelial function, and their relationship in patients with dyslipidemia.

Assessment
Primary outcomes Primary endpoint is the change in the plasma S1P concentration and endothelial function from baseline to week 8.
Key secondary outcomes (1) The change in lipid profiles (total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides) from baseline to week 8.
(2) The change in fasting plasma glucose, C-reactive protein, serotonin, malondialdehyde-modified low-density lipoproteitn (MDA-LDL) from baseline to week 8.
(3) The change in urine albumin excretion from baseline to week 8.
(4) The change in brachial-ankle pulse wave velocity from baseline to week 8.
(5) The change in the number of progenitor cell (CD34+ cell) from baseline to week 8.
(6) The change in the number of endothelial progenitor cells (positive for DiI-acLDLuptake and FITC-lectin binding staining) from baseline to week 8.
(7) The change in brachial blood pressure, estimated central aortic pressure, and heart rate from baseline to week 8.

Interventions/Control_1 SEE-THRU Lipid is a 8-week, prospective, randomized, open, blinded-endpoint (PROBE) study. After a screening phase for eligibility, baseline data are obtained. Then, patients are assigned to receive rosuvastatin (2.5mg, daily) for 8 weeks. Antidyslipidemic drugs other than rosuvastain are not allowed but other medication, if any at baseline, is continued and not changed throughout the study period.
Interventions/Control_2 After a screening phase for eligibility, baseline data are obtained. Then, patients are encouraged to modify life style without receiving antidyslipidemic drug for 8 weeks. Antidyslipidemic drugs are not allowed but other medication, if any at baseline, is continued and not changed throughout the study period.
