Methods 38 patients with dyslipidemia were treated with statins for 8 weeks. Before and after the therapy, serum soluble endothelial leucocyte adhesion molecule(sELAM), soluble intercellular adhesion molecule 1 (sICAM 1), soluble vascular cell molecule 1(sVCAM 1) and the expression of L Selectin, intercellular adhesion molecule (ICAM) 1, ICAM 3 on leucocytes were examined. Serum interleukin 1β(IL 1β), tumour necrosis factor (TNF) were tested as well. Results After the treatment, sELAM (74.2±16.8) ng/ml vs (55.8±16.3) ng/ml, sICAM 1(441±110) ng/ml vs (321±92) ng/ml were reduced markedly (both P <0.01), but sVCAM 1 (582±67) ng/ml vs (547±72) ng/ml was not reduced significantly. Individual sELAM and sICAM 1 were positively correlated with TC( P <0.005 and P < 0.01) and negatively with HDL C (both P <0.01). The percentages of monocytes and lymphocytes positive for L Selectin were increased (45.5±11.4)% vs (56.7±9.1)% and (15.9±7.2)% vs (23.1±5.7)%, P < 0.05, P <0.01, respectively, whereas percentages of ICAM 1 positive monocytes and lymphocytes were reduced (91.1±6.1)% vs (78.3±5.0)% and (23.4±6.2)% vs (14.6±5.3)%, P <0.05 and P <0.01, respectively; mean fluorescence intensity of ICAM 3 on leukocytes was lowered, P <0.01. Serum IL 1 β was declined, and the individual change value was well correlated with the changes of percentage of L Selectin positive lymphocytes and mean fluorescence intensity of ICAM 3 (both P <0.01). Conclusion Statins could reduce serum soluble adhesion molecules, and regulate the expression of adhesion molecules on leucocytes and the production of cytokines, which was realized possiblely through modulating serum lipid.
