RESUMO
Objective To explore the correlation between cystatin C (Cys C) and intima-media thickness of carotid artery (CIMT) in patients with hypertension.Methods One hundred and one patients with hypertension (hypertension group) and 54 healthy people (control group) were enrolled in this study.The level of serum Cys C was measured and CIMT was detected by B ultrasound.The correlation between Cys C and CIMT was analyzed.Results The level of Cys C and CIMT in hypertension group were significantly higher than those in control group [(0.92 ±0.21) mg/L vs.(0.85 ±0.20) mg/L,(0.91 ±0.16) mm vs.(0.65 ± 0.15) mm] (P ＜ 0.05 or ＜ 0.01).Multiple linear correlation analysis showed that Cys C and CIMT was positively correlated in total population or hypertension group or control group (r =0.412,0.443,0.315,P ＜0.01).Conclusion Serum Cys C is associated with the degree of hypertension arteriosclerosis,and Cys C may be involved in atherosclerosis.

RESUMO
AIM: To examine the effects of monocyte-endothelium interaction on the expression of CD36 in monocytes and observe the functions of cytokines in this process. METHODS: The monocytes and endothelial cells were cultured alone or cocultured together to form different cell culture conditions. The level of M-CSF in culture medium was determined by enzyme linked immune sandwich assay(ELISA) technique, and the expression of CD36 in monocytes was determined by flow cytometry. RESULTS: The expression of CD36 in monocytes was low in monocytes cultured alone but increased significantly when monocytes and endothelial cells were cocultured(P
