【摘要】:目的了解孤独症儿童血清中脑源性神经营养因子(brain-derived neurotrophic factor,BDNF)的水平及其与孤独症病情的关系。方法依据《精神疾病诊断与统计手册-第4版(DSM-Ⅳ)》选择已明确诊断的孤独症儿童53例,并按照儿童期孤独症评定量表(the children autism rating scale,CARS)标准对孤独症儿童进行病情分级;另选59例健康儿童作为对照。采用酶联免疫吸附测定法(enzyme-linked immunosorbent assay,ELISA)检测所有受试儿童血清中BDNF水平。采用SPSS 20.0统计软件做两组样本t检验进行统计分析。结果孤独症儿童血清BDNF水平为(28.49±11.01)pg/ml,对照组儿童血清BDNF水平为(21.32±11.12)pg/ml,经统计学分析显示差异有统计学意义(t=3.42,P=0.001)。轻度孤独症儿童血清BDNF水平高于对照儿童(t=3.11,P=0.002),重度孤独症儿童血清BDNF水平与对照组儿童相比有增高趋势,但差异无统计学意义(t=1.49,P=0.142),轻度孤独症与重度孤独症儿童之间的BDNF水平差异无统计学意义(t=1.20,P=0.237)。孤独症患儿男性和女性之间BDNF水平差异无统计学意义(t=0.19,P=0.847)。结论孤独症儿童血清中BDNF水平高于对照组儿童,其中轻度孤独症儿童高于对照儿童,而重度孤独症儿童与对照儿童间差异无统计学意义。提示BDNF可能是孤独症患病风险的保护因素。
