摘要： 目的探讨肝气郁结证患者脑电非线性动力学变化规律。方法15例肝气郁结症患者和15例正常受试者按年龄、性别配对,用参数PD2对安静闭眼、安静睁眼、睁眼心算3种状态下的脑电数据进行分析。结果3种状态下肝气郁结证患者大脑皮质的PD2较正常人增高,一直维持在较高水平,并随刺激条件的增多,两者之间PD2的差异逐渐缩小。结论脑电非线性分析能相对客观和准确地观测到肝气郁结证患者大脑皮质的变化,可用于肝气郁结证脑机制的研究。

Abstract: Objective To investigate the changes of non-linear dynamics characteristics of electroencephalogram(EEG) in patients with the stagnation of Liver-Qi syndrome.Methods 15 Liver-Qi stagnation syndrome patients and 15 normal persons were paired by sex and age.The data of EEG under three states(eyes closed,eyes opened,and mental arithmetic with eyes opened) were analyzed by the parameter of point-wise correlation dimension(PD2).Results PD2 of the stagnation of Liver-Qi syndrome group increased significantly compared with that of the healthy control group and always maintain high level.The difference of PD2 between two groups was gradually reduced along with the increase of stimulated condition.Conclusion Non-linear dynamic analysis is more appropriate for the study of mental functions changes of stagnation of Liver-Qi syndrome and can be used to investigate the brain mechanism of the stagnation of Liver-Qi syndrome.
