摘要 目的:探讨肥胖儿童非酒精性脂肪肝炎(nonalcoholic steatohepatitis,NASH)与脂肪因子的关系。方法:对符合NASH诊断的23例患儿、符合单纯性肥胖诊断的17例儿童以及20例正常儿童分别检测血丙氨酸氨基转移酶(ALT)、游离脂肪酸、瘦素、脂联素、肿瘤坏死因子(TNF-α),比较它们的水平并分析ALT与各指标的关系。结果:NASH组患儿游离脂肪酸、瘦素、TNF-α水平高于单纯肥胖组和对照组(P<0.05,P<0.01),而脂联素水平低于另两组(P<0.05,P<0.01)。相关分析显示:ALT与游离脂肪酸、瘦素、TNF-α各指标间存在正相关(r=0.407,P<0.01;r=0.338,P<0.05;r=0.372,P<0.05),与脂联素间存在负相关(r=-0.378,P<0.05)。结论:NASH患儿高血脂、高瘦素血症、高TNF-α单独或共同构成NASH的发病因素之一,而脂联素则起保护作用。
