精神分裂症首次发病患者的执行功能和学习能力

Objective To investigate the executive function and the learning ability of the patients with first-episode schizophrenia, and their relationships with psychiatric symptoms. Methods Fifty firstepisode schizophrenia patients and fifty age- and gender-matched healthy controls were tested by a computerized version of Tower of London ( TOL ) test. The scores of the Positive and Negative Syndrome Scale( PANSS ) were larger than 60 in the group of schizophrenia patients. Results The numbers of the correct answer[xt :( 14.62 ±4. 12 ),x2 :( 14. 80 ±4.70 )] during the first session and the second session of the TOL test were significantly lower in patients than the control group[x1 :( 17.48 ± 3.79 ),x2 :( 18.68 ±3.19 )] , and the reaction time [t1 :( 9. 27 ±4. 37 )seconds, t2 :( 9. 51 ±5.58 )seconds] of the two sessions of TOL were longer than the control group[t1 :( 7. 28 ± 2. 04 )seconds, t2: ( 6. 67 ± 1.51 )seconds] , P ＜0. 01. For the control group, x2 was significantly greater than x1, and t2 shorter than t1( P ＜0. 01 ),while for the patients group, there was no difference between the performances of the first session and the second session. The scores of TOL in the schizophrenia patients were correlated with the negative symptom score of PANSS( P＜ 0. 05 )and were not correlated with the scores of other subscales of PANSS( P ＞ 0.05 ).Conclusion The executive function and the learning ability of schizophrenia are impaired and the cognitive dysfunction maybe correlated with negative symptoms.

Objective To compare the differences of psychopathologic symptoms between smokers and non-smokers in chronic and first-episode,drug-nalve schizophrenics.then it was attempted to explain the reasons why there is higher rate of smoking behavior in schizophrenia.Methods In all.427 male chronic schizophrenic patients(332 smokers and 95 non-smokers)and 63 male first-episode drug-naive patients with schizophrenia(22 smokers and 41 non-smokers)were collected.All patients were assessed with the Positive and Negative Syndrome Scale(PANSS).Results In chronic patients.the item scores of poor rapport and passive/apathetic social withdrawal of PANSS negative subscale were significantly lower in smokers than non-smokers(3.9 ±1.5 vs.4.4±1.7;3.6±1.6 vs.4.0±1.7.respectively,P＜0.05),and so was the total scores of PANSS negative subscale(24.0±8.2 vs.26.3±9.5).In first-episode.drug-ndive patients.the itern scores of emotional withdrawal and passive/apathetic social withdrawal of PANSS negative subscale were significant lower in smokers than non-smokers(2.7±1.3 vs.3.5±1.3:2.7±1.3 vs.3.5±1.4,respectively,P＜0.05).Conclusion It is suggested there are positive effects of cigarette smoking on the psychopathological symptoms of patients with schizophrenia,which misht be one of the mechanisms for higher rates of smoking behavior in schizophrenia.

目的 探讨汉族人群精神分裂症患者是否存在听觉惊跳反射缺陷及抗精神病药的影响.方法 第1代药物组:服用第1代抗精神病药的慢性精神分裂症男性患者25例;氯氮平组:服用氯氮平的慢性精神分裂症男性患者25例;对照组:身体健康的男性25名;3组的年龄和受教育年限均匹配.对上述3组进行听觉刺激惊跳反射检测,并使用阳性和阴性症状量表(PANSS)评定精神分裂症患者的临床精神病理症状.结果 (1)第1代药物组惊跳反射的反应波幅(SR)[(553.6±516.9)mV]明显低于对照组[(942.0±447.3)mV,P=0.009],氯氮平组的SR[(755.9±439.4)mV]介于上述2组之间,但与2组间的差异均无统计学意义(P＞0.05);(2)第1代药物组惊跳反射的适应性(HAB)[(17.8±35.8)%]明显低于对照组[(44.9±28.9)%,P=0.027],氯氮平组的HAB[(22.9±34.1)%]介于上述2组之间,但与2组间的差异均无统计学意义(P＞0.05);(3)当时间间隔(LI)为120 ms时,第1代药物组的惊跳反射弱刺激抑制(prepulse inhibition,PPI)显著小于对照组(P=0.024),氯氮平组的PPI值介于上述2组之间,但与2组间的差异均无统计学意义(P＞0.05);LI为30 ms或60 ms时,3组间PPI的差异无统计学意义(P＞0.05);(4)第1代药物组和氯氮平组患者不同LI的PPI与其临床病理症状可能不存在相关(P＞0.05).结论 精神分裂症患者可能存在听觉惊跳反射弱刺激抑制的缺陷;氯氮平可能能部分改善精神分裂症患者对惊跳反射的脱抑制.     

认知矫正治疗慢性精神分裂症患者认知功能缺陷的随机对照研究

目的 探讨认知矫正治疗(CRT)和计算机认知矫正治疗(CCRT)对精神分裂症患者认知缺陷的疗效.方法 180例慢性期病情稳定的精神分裂症患者随机分成3组,CCRT组、CRT组和工娱治疗(WAT)组.CCRT组108例,治疗以自主开发的计算机认知矫正治疗系统为工具,每周4次,每次45 min,持续3个月;CRT组36例,以Ann Delahunty和Rodney Morice等制定的神经认知矫正手册(汉化)为治疗工具,在治疗师的指导下进行认知矫正治疗;WAT组36例,接受相同时间的工娱治疗.3组在治疗频度和治疗持续时间上完全一致.治疗前后及治疗结束后第3个月分别进行临床症状和认知功能评定,内容包括阳性和阴性症状量表(PANSS)、精神分裂症认知功能成套测验(MCCB)、威斯康星卡片分类测验(WCST).结果 治疗结束后及随访第3个月时,CCRT组和CRT组在改善WCST完成分类数、连线测验、空间广度方面显著优于WAT组(P均＜0.05);CCRT组在空间广度方面明显优于CRT组(P＜0.05),CRT组在符号编码方面则优于CCRT组(P＜0.05);3组的临床症状在治疗结束及随访阶段无明显变化.结论 CCRT和CRT均能显著改善慢性精神分裂症患者的认知功能,主要表现在记忆、执行功能、精神运动速度方面;CCRT在空间记忆方面较CRT有优势,CRT在精神运动方面较CCRT有优势,CCRT和CRT在执行功能、记忆、精神运动速度等方面的疗效能持续3个月.     

奎硫平与利培酮治疗精神分裂症的对照研究

目的验正奎硫平治疗精神分裂症的疗效及安全性。方法将121例精神分裂症患者随机分为奎硫平组（61例）与利培酮组（60例）,并进行对照研究,两药治疗剂量分别为200—800mg／d,2～5mg／d,疗程8周。采用阳性和阴性症状量表（PANSS）、简明精神病评定量表（BPRS）、治疗中出现的症状量表（TESS）进行评定及有关实验室检查。结果治疗结束时,两组PANSS和BPRS评分较入组时均显著减低（P〈0．01）,PANSS减分率奎硫平组为（65．7±28．1）,利培酮组为（66．4±27．3）,临床总有效率奎硫平组为70．5％,利培酮组为73．3％;两组疗效差异无显著性。奎硫平组的不良反应较利培酮组少,其中活动减少、震颤、扭转痉挛、静坐不能、口干、视物模糊、便秘、头晕的发生率显著少于利培酮组（P〈0．01或0．05）。结论国产奎硫平治疗精神分裂症的疗效与利培酮相当,部分不良反应较利培酮轻而少,是一种有效、耐受性较好的新型抗精神病药。
