Abstract:
ObjectiveTo explore the effect of aerobic exercise on serum leptin,interleukin-18 (IL-18),soluble intercellular adhesion molecule-1 (sICAM-1),C reaction protein (CRP) concentration,and homeostasis model assessment insulin resistance (HOMA-IR) of patients with metabolic syndrome ( MS),and to explore its mechanism.MethodsForty sedentary patients with MS were randomly divided into exercise group and fenofibrate group.Patients in exercise group were trained at anaerobic threshold intensity (30 min/times) for 12 weeks (5 times/wk).Patients in fenofibrate group were treated with fenofibrate 200 mg every night.Serum leptin,IL-18,CRP,and sICAM-1 concentration were measured by enzyme linked immunosorbent assay (ELISA).Twenty healthy subjects were selected as the control group.ResultsSerum concentration of leptin [ ( 26.04 ± 9.07 ) ng/ml vs ( 8.32 ± 2.94 ) ng/ml,t =12.72,P ＜0.01 ],IL-18[ (308.27 ±50.39)pg/ml vs (230.60 ±29.15)pg/ml,t =6.41,P ＜0.01 ],CRP[ (2.65±0.57)ng/ml vs ( 1.26 ±0.23) ng/ml,t =9.69,P ＜0.01 ],sICAM-1 [ (331.89 ±60.08) ng/ml vs (246.43±39.32)ng/ml,t =5.98,P ＜0.01],and HOMA-IR(4.38 ±2.06 vs 2.12 ± 0.50,t =4.81,P ＜ 0.01 ) of patients with MS were significantly increased compared to the control.Serum concentration of leptin[(26.38±10.85)ng/ml vs (19.63 ±6.27)ng/ml,t =2.22,P ＜0.05],IL-18[(309.40 ±49.77)pg/ml vs (291.80 ±39.21)pg/ml,t =2.33,P ＜0.05],CRP[ (2.73 ±0.72)ng/ml vs (2.28 ±0.38)ng/ml,t =3.41,P ＜0.01 ],sICAM-1 [ (333.85 ±55.97) ng/ml vs (306.24 ±50.55) ng/ml,t =3.16,P ＜0.01],and HOMA-IR(4.53 ±2.39 vs 2.89 ±0.69,t =2.87,P ＜0.01 ) were significantly decreased after training for 12 weeks.ConclusionsAerobic exercise is one of the effective treatments of patients with MS.Its underlying mechanism may be associated with reduction of serum inflammatory adipokine concentration,and improvement of vascular endothelial function and insulin resistance.
