摘要目的 探讨艾司西酞普兰对惊恐障碍患者情绪图片信息认知偏倚的影响.方法 选择符合CCMD-3惊恐障碍诊断标准的30例患者作为试验组,与试验组匹配性别、年龄的30例健康人作为对照组.实验组予艾斯西酞普兰治疗8周.两组分别在治疗前以及8周后予情绪图片刺激的点探测任务检测,比较治疗前以及8周后反应时以及注意偏向分差别.结果 试验组8周后汉密顿焦虑量表评分[(7.81 ±2.52)分]明显低于治疗前[(17.23 ±3.12)分](P=0.002).重复测量ANOVA显示,探测位置主效应显著[F(1,58)=4.34,P=0.031],异侧位置的反应时长于同侧位置;情绪面孔图片类型与组间水平交互作用显著[F(1,58)=19.21,P=0.000];探测位置与组间水平交瓦作用显著[F(1,58)=16.15,P=0.000];情绪面孔图片类型与探测位置交互作用显著[F(1,58)=9.25,P=0.015];情绪面孔图片类型×探测位置×组间水平交互作用显著[F(1,58)=7.31,P=0.002],ISD比较显示试验组对恐惧面孔图片异侧位置的反应时长于同侧位置(P=0.0009).试验组治疗8周后对恐惧面孔图片反应时以及注意偏向分明显低于治疗前(P=0.032,0.008).结论 惊恐障碍患者对恐惧面孔图片信息表现出认知偏倚,艾斯西酞普兰可能具有改善认知偏倚的作用.

abstractsObjective To investigate the effect of escitalopram treatment on cognitive bias to the emotional facial information in patients with panic disorder. Methods 30 patients met CCMD-3 criteria for panic disorder were enrolled as research group and marched sexual and age 30 healthy persons enrolled as control group. Patients were treated with escitalopram for 8 weeks. All participants measured with dot-probe task of emotional facial information at base and after 8 weeks. RTs and attentional bias scores were compared respectively. Results After 8 weeks,HAMA scores (7. 81 ± 2. 52) in research group were lower than that of at base ( 17. 23 ± 3. 12) (P = 0.002). A repeated measure ANOVA revealed a significant probe site main effect (F(1,58) =4. 34, P = 0.031 ) , RTs of antarafacial site were longer than that of homonymy site. It revealed a significant probe site and group interaction(F(1,58) =16.15, P=0.000) ,a significant emotional facial information type and probe site interaction(F(1,58)=9.25, P =0.015) ,and a significant emotional facial information type × probe site× group interaction(F(1,58) =7. 31, P = 0. 002). LSD test showed that RTs of antarafacial site to fear facial information in research group were longer than that of homonymy site(P = 0.0009). RTs and attention bias scores of antarafacial site to fear facial information after 8 weeks in research group were lower than that of at base(P=0.032,0.008). Conclusion Patients with panic disorder have the cognitive bias to the fear facial emotional stimulus, and escitalopram treatment might improve the cognitive bias.
