Methods: Serum level of NO and activity of SOD were measured in 152 patients with traffic accidents and in 60 control subjects. All subjects were assessed with the Eysenck Personality Questionnaire (EPQ). Results: NO and SOD were significantly higher in patients as compared to controls ( P <0.01). Correlation analysis showed that SOD score negatively correlated with N score of EPQ ( P <0.05), and NO score positively correlated with N and P scores of EPQ ( P <0.05).Conclusion: Healthy personality may play an important role to enhance the ability to cope with stress.展开更多
目的探讨精神分裂症内隐语义记忆的缺损特征。方法选取年龄、性别、文化程度等匹配的精神分裂症患者组36例及正常对照组34例,利用相关词、非相关词及非词研究内隐语义记忆缺损特征,实验包括直接启动任务和间接启动任务。记录反应时和正...目的探讨精神分裂症内隐语义记忆的缺损特征。方法选取年龄、性别、文化程度等匹配的精神分裂症患者组36例及正常对照组34例,利用相关词、非相关词及非词研究内隐语义记忆缺损特征,实验包括直接启动任务和间接启动任务。记录反应时和正确率。结果反应时数据及正确率数据分别行2×2×2重复测量的方差分析,未发现任何主效应。对于反应时而言,存在三者之间的交互效应(F(1,67)=4.6,P<0.05)。在直接启动和间接启动任务中,精神分裂症组和正常对照组反应时启动指标差异均存在统计学意义(18±6 vs 14±3,P<0.01;20±8 vs 15±9,P<0.05)。在直接启动任务中,精神分裂症组错误数启动指标高于正常对照组(10±5 vs 8±3,P<0.05),而间接启动任务两组差异无统计学意义(均P>0.05)。结论精神分裂症患者内隐语义启动模式存在缺陷,并可能受到病程及阳性思维障碍影响。展开更多
目的:利用情绪Stroop任务测量海洛因依赖者是否存在对吸毒相关汉字线索的注意偏向。方法:男性海洛因依赖者(研究组)与健康志愿者(对照组)各15例,采用NeuroSCAN工作站STIM2编程,记录并比较研究组和对照组对3类汉字(包括海洛因毒品相关类...目的:利用情绪Stroop任务测量海洛因依赖者是否存在对吸毒相关汉字线索的注意偏向。方法:男性海洛因依赖者(研究组)与健康志愿者(对照组)各15例,采用NeuroSCAN工作站STIM2编程,记录并比较研究组和对照组对3类汉字(包括海洛因毒品相关类、中性、音乐类、)的反应时(reaction time,RT)及正确率。结果:两组对3类汉字线索的反应正确率之间无差异;与对照组相比,研究组对毒品相关汉字的反应时明显延长(789.23 ms±s102.53 ms vs 701.27 ms±s69.48 ms,P<0.05);而对音乐汉字的反应时显著缩短(630.52 ms±s84.33 vs 739.65ms±s92.28 ms,P<0.01)。重复测量的方差分析发现,存在刺激类别的主效应(F(2,28)=8.94,P<0.01)以及组别和刺激类别的交互效应(F(2,28)=9.58,P<0.01),研究组对海洛因相关汉字的反应时间与吸毒时间呈正相关(r=0.563,P<0.05)。结论:海洛因依赖者对吸毒相关的汉字线索存在着注意偏向。展开更多
