Abstract
OBJECTIVE The aim is to compare atorvastatin versus rosuvastatin on secondary percutaneous coronary intervention (PCI) rate and explore risk factors in coronary heart disease (CHD) patients. METHODS A cohort study with 283 CHD subjects was launched from 2011 to 2015. Cox proportional hazards regression model, Receiver Operating Characteristic (ROC) and nomogram were used to compare the effect of atorvastatin and rosuvastatin on secondary PCI rate and disease risk factors. Even why the two statins had different effects based on gene expression profile analysis has been explored. RESULTS Gene FFA (Freely fatty acid), AST (Aspartate Transaminase) and ALT (Alanine transaminase) showed the statistical difference between the four statin groups (P<0.05). In the AA group (Continuous Atorvastatin usage), albumin was a risk factor (Hazard Ratio (HR):1.076, 95%CI (1.001, 1.162), p<0.05). In the AR group (Start with Atorvastatin usage, then change to Rosuvastatin usage), ApoA was a protective factor (HR:0.004, 95%CI (0.001, 0.665), p<0.05). GLB (Galactosidase Beta) was a risk factor (HR:1.262, 95%CI (1.010, 1.576), p<0.05). In RR group (Continuous Rosuvastatin usage), ApoE was a protective factor (HR:0.943, 95%CI (0.890, 1.000), <0.05). ALT was a risk factor (HR:1.030, 95%CI (1.000, 1.060), p<0.05). CONCLUSION Patients in the RA group had the lowest secondary PCI rate. ALT was a risk factor in the RR group. Gene Gpt (Glutamic Pyruvic Transaminase) encoded for one subtype of ALT had a significantly different expression in different statin groups.

Abstract
Anemia is a common clinical problem in end-stage renal disease (ESRD). Despite adequate erythropoiesis-stimulating agent (ESA) supplementation, some ESRD patients still have suboptimal hemoglobin levels, and iron deficiency and inflammation are recognized as the two most common causes. Hepcidin, a newly discovered key regulator of iron homeostasis, is found to be accumulated in ESRD. As it controls iron uptake and release, better reflecting real-time iron demand and availability, hepcidin might become a target in the management of iron deficiency and ESA resistance in dialysis patients. For their pleiotropic functions apart from lipid-modulation, statins are also used as anti-inflammatory or immune-modulating agents. In this study, we applied simvastatin for the purpose of influencing serum prohepcidin level in a group of maintenance hemodialysis patients. Thirty-three ESRD patients undergoing hemodialysis were enrolled and assigned to experimental and hemodialysis control groups according to their lipid profile. Nineteen healthy adults were chosen as a normal control group. The subjects in the experimental group took 20 mg simvastatin orally per night for eight weeks, and those in the hemodialysis control group took no statins or any other lipid-modulating drugs. Before and after the experiment, the serum prohepcidin concentrations, plasma IL-6, and serum C-reactive protein (CRP), ferritin, hemoglobin, albumin, total cholesterol, glycerinate, and LDL and HDL cholesterol levels were determined. Of the 33 hemodialysis patients, the serum prohepcidin concentration was (175.8 +/- 52.9) ng/mL, significantly higher than that in the normal control group (149.5 +/- 24.2) ng/mL (P = 0.048). In the experimental group, the serum prohepcidin level was (156.7 +/- 51.9) ng/mL before treatment, and (190.6 +/- 49.6) ng/mL after eight weeks (P = 0.127). In the hemodialysis control group, the serum prohepcidin level was (190.6 +/- 49.6) ng/mL at the beginning, and (193.5 +/- 36.0) ng/mL after eight weeks (P = 0.728). In the experimental group, after taking simvastatin for eight weeks the serum total cholesterol and triglyceride levels had lowered by 18.6% (P = 0.004) and 55.1% (P = 0.007), respectively. The plasma IL-6, serum CRP, ferritin, hemoglobin, albumin, and LDL and HDL cholesterol levels in both the hemodialysis group remained unchanged. According to our preliminary study, eight weeks of 20 mg simvastatin did not significantly change the serum prohepcidin, high-sensitive CRP, or IL-6 concentrations in the group of maintenance hemodialysis patients.
