摘要 目的 了解Stroop色词测验效应(SCWT)对轻微肝性脑病(MHE)患者认知功能的检测及对MHE的初筛价值.方法 回顾分析2012年1月至2014年12月我院诊治的60例轻、中度肝硬化并行Stroop色词测验患者(病例组)的临床资料,患者年龄18-65岁.以同期60例年龄、文化程度(非文盲)相匹配的健康体检者为对照(对照组),比较两组SCWT的各参数.数字连接试验-A和数字广度测试检测中1项异常即诊断为MHE,比较SCWT各参数的差异,评估其初筛MHE的价值.结果 SCWT中,病例组患者卡片2、卡片3、卡片4以及反映字词干扰量(SIE)和颜色SIE的耗时数及错误数[分别为(17.28±0.69)、(12.96±1.10)、(30.30±1.40)、(5.00±0.90)和(13.74±1.22)s,(0.36±0.10)、(0.50±0.11)、(0.50±0.11)、(5.00±0.90)和(1.98±0.23)次],均高于对照组[分别为(10.18±0.57)、(7.68±0.39)、(15.68±0.33)、(1.94±0.37)和(6.56±0.70)s,(0.02±0.02)、(0.10±0.04)、(0.10±0.04)、(0.04±0.02)和(0.20±0.08)次],差异均有统计学意义(t值分别为12.95、6.98、8.19、7.02、11.91和10.09、8.97、8.15、17.94、11.37,均P=0.00);病例组卡片1耗时数和错误数[分别为(7.10±0.40)s,(0.04±0.03)次]和对照组[分别为(6.72±0.36)s,(0.02±0.02)次]相比,差异均无统计学意义(t值分别为1.89、1.91,均P=0.06).字词SIE、颜色SIE、字词SIE+颜色SIE的诊断敏感度分别为0.83(50/60)、0.88(53/60)、0.98(59/60),特异度分别为0.87(52/60)、0.80(48/60)、0.83(50/60).结论 Stroop色词测验是简便、有效的初筛MHE的辅助手段之一. Objective To assess the application of Stroop color-word test ( SCWT) for screening of minimal hepatic encephalopathy (MHE) in patients with liver cirrhosis.Methods Sixty patients aged 18-65 years with liver cirrhosis and 60 age, education level-matched healthy subjects were examined with SCWT.The SCWT indexes were compared between two groups .MHE was identified when patients had abnormal number connection test-A (NCT-A) and/or digit symbol test (DST).Results Time consuming and errors of card 2, 3, 4 and Stroop interference effects ( SIE) reflecting word-interference and color-interference in SCWT were increased significantly in liver cirrhotic patients [(17.28 ±0.69)sec,(12.96 ± 1.10)sec, (30.30 ±1.40)sec, (5.00 ±0.90)sec, (13.74 ±1.22)sec, (0.36 ±0.10) times, (0.50 ± 0.11) times, (0.50 ±0.11) times, (5.00 ±0.90) times,(1.98 ±0.23) times, respectively] compared to those in healthy subjects [(10.18 ±0.57) sec,(7.68 ±0.39)sec,(15.68 ±0.33)sec,(1.94 ±0.37) sec, (6.56 ±0.70)sec, (0.02 ±0.02) times,(0.10 ±0.04)times,(0.10 ±0.04)times,(0.04 ±0.02) times,(0.20 ±0.08) times, respectively; t =12.95, 6.98, 8.19, 7.02, 11.91, 10.09, 8.97,8.15, 17.94,11.37,all P=0.00];while there were no significant differences in time consuming and errors of card 1 between liver cirrhotic patients [ ( 7.10 ±0.40 ) sec and ( 0.04 ±0.03 ) times ] and healthy subjects [(6.72 ±0.36)sec and (0.02 ±0.02) times; t=1.89, 1.91, both P=0.06].The sensitivity of word SIE, color SIE and word SIE +color SIE of SCWT for primary screening of MHE was 0.83(50/60), 0.88 (53/60) and 0.98(59/60) respectively, whereas the specificity was 0.87(52/60), 0.80(48/60) and 0.83(50/60) respectively.ConclusionThe SCWT may serve as a convenient , effective and reliable tool for primary screening MHE.
