| 目的观察单纯性肥胖症儿童运动训练前、后血管内皮分泌功能，氧化低密度脂蛋白，体重改变的特点。 方法收集8~14岁单纯性肥胖症儿童30例（肥胖组），正常儿童30例（对照组）。 肥胖组进行为期8周、每周5 d、每天1 h的运动训练，测定其运动训练前、后的内皮素（ET）、6-酮前列环素（6-K-PGF1α）、一氧化氮（ＮO）、氧化低密度脂蛋白（OX-LDL）及体重；测定对照组儿童的内皮素（ET）、6－酮前列环素（6-K-PGF1α）、一氧化氮（ＮO）、氧化低密度脂蛋白（OX-LDL）。 结果肥胖组儿童的ET、OX-LDL明显升高，NO、6-K-PGF1α明显降低，与对照组比较，差异有显著性（P<0.01）。运动训练后肥胖组儿童的ET、OX-LDL明显下降，而6-K-PGF1α、NO明显升高，与治疗前比较，差异有显著性(P<0.01)。 结论单纯性肥胖症儿童血管内皮分泌功能及OX-LDL发生紊乱，而运动训练能使其功能得到改善。 |

| Objective To observe the changes of the function of vascular endothelial secretion, levels of OX-LDL and body-weight of obese children after exercise intervention. MethodsThirty children with obesity at the age of 8 to 14 years and 30 normal children were enrolled in this experiment. The obese children (exercise group) received a session of 1 hour's exercise each day, 5 days a week for 8 weeks. The levels of ET, 6－K-PGF1α,NO, OX-LDL and body-weight were then measured and compared with that of their pre-exercise state and that of the normal children (control group). ResultsThe levels of ET and OX-LDL were increased, while the levels of NO and 6－K-PGF1α were decreased in the obese children in comparison with the normal controls, the difference was statistically significant (P<0.01). After exercises, the levels of ET and OX-LDL decreased, while 6－K-PGF1α and NO increased significantly as compared with those before exercise in the obese children(P<0.01). ConclusionThe function of vascular endothelial secretion and levels of OX-LDL were disordered in children with obesity. Exercise can definitely improve the metabolic functions of children with obesity. |
