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.

BACKGROUND:Most of the traumatic brain injury and stroke survivors have foot drop and varus deformity, that need to be treated with ankle-foot orthosis. OBJECTIVE:To investigate the advantages and effect of early application of front-ankle-foot orthosis on the walking function of the patients with hemiplegia after stroke. METHODS:The clinical data of 54 patients with hemiplegia after stroke treated in the Changshu No. 2 People’s Hospital from June 2008 to October 2009 were retrospectively analyzed. The patients treated with front-ankle-foot orthosis were the front group (n=28), and the patients treated with rear-ankle-foot orthosis were the rear group (n=26). Al the patients received 10 m maximum walking speed test, and the recovery of walking function of the patients in two groups were observed daily. RESUTLS AND CONCLUSION:There were no patients exited and dead in the observation period. The activities of daily living Barthel index in the front-ankle-foot orthoses group (60.0±12.9) was significantly higher than that in the rear-ankle-foot orthoses group (59.1±10.9), and there was no significant difference in the activities of daily living Barthel index between two groups (P>0.05). For the 10 m maximum walking speed test, the walking speed of (39.6±11.6) m/min in the front-ankle-foot orthosis group was significantly faster than that of (33.0±12.4) m/min in the rear-ankle-foot orthosis group (P<0.05). Front-ankle-foot orthosis is more appropriate for patients with hemiplegia after stroke to improve the walking speed.
