吸烟对精神分裂症男性患者精神病理症状的影响

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.

α7烟碱型乙酰胆碱受体与精神分裂症认知功能(综述)

本文简述了α7烟碱型乙酰胆碱受体(α7n AChR)的结构与功能,着重回顾了基于α7 n A C hR与精神分裂症认知功能关联在分子遗传与治疗药物新靶标等方面的研究。α7 n A C hR的异常参与精神分裂症认知功能受损的发生,其激动剂能够改善精神分裂症患者的认知功能,并提示作为调节其内源性拮抗剂KYNA水平的关键,KAT-2也有望成为药物治疗精神分裂症患者认知功能受损的新靶点。     

吸烟对慢性精神分裂症男性患者抗精神病药物副作用影响的研究

目的分析吸烟对精神分裂症患者抗精神病药物副作用的影响，探索精神分裂症高吸烟率的可能原因。方法收集慢性精神分裂症男性吸烟和非吸烟患者共427例，其中吸烟患者332例，非吸烟患者95例。使用锥体外系副作用反应量表（ARatingScaleforExtrapyramidalSideeffects，RSE—SE）评价患者抗精神病药物的副作用。结果精神分裂症吸烟和非吸烟组在RSESE总分及其各分条目得分上的差异无统计学意义（P〉0．05）。结论精神分裂症患者的高吸烟率可能与吸烟对抗精神病药物副作用的影响无关。     

迟发性运动障碍脑MRI研究进展

迟发性运动障碍(Tardive Dyskinesia,TD)为长期应用抗精神病药后,出现异常不自主运动的综合征[1-2].使用典型抗精神病药治疗10年以上的病例,TD年发生率高达50％,具有明显的致残性和不可逆性[3].随着非典型抗精神病药物的应用,迟发性运动障碍的发生率和流行率似乎相对稳定[4].     

精神分裂症患者阴性症状与语音情绪识别、述情障碍的关系

目的:探讨精神分裂症患者的阴性症状与语音情绪识别、述情障碍的关系。方法:选取符合美国精神障碍诊断与统计手册第4版(DSM-IV)诊断标准的精神分裂症患者135例,年龄和受教育年限相匹配的正常对照73例。使用语音情绪识别任务、多伦多述情障碍量表和阴性症状自评量表进行测评。结果:精神分裂症组对不同情绪(愤怒、厌恶、恐惧、悲伤、惊讶和讽刺)的正确识别率均低于正常对照组(均P <0.05)。患者组述情障碍的难以识别情绪、难以描述情绪因子和总分高于对照组(均P <0.05)。述情障碍量表的总分及3个因子与阴性症状自评量表(SNS)得分呈正相关(r=0.31-0.51,均P <0.05),而悲伤、和惊奇与SNS得分呈负相关(r=-0.18、-0.21,均P <0.05)。逐步回归分析显示,难以描述情绪因子与SNS得分正向关联(β=1.26),悲伤情绪因子得分与SNS得分负向关联(β=-0.59)。结论:本研究提示精神分裂症患者存在语音情绪识别障碍和述情障碍,且阴性症状的严重程度与语音情绪识别和述情障碍的关系密切。     

吸烟对精神分裂症认知和临床症状及药物不良反应的影响

de Leon和Diaz[1]的meta分析结果显示,精神分裂症患者吸烟行为非常普遍,吸烟率约为40%～90%,明显高于正常人群和其他精神疾病人群.

帕利哌酮棕榈酸盐多次给药的稳态血药浓度与临床安全性的研究

目的研究帕利哌酮棕榈酸盐在精神分裂症患者中多次给药的血浆药物浓度水平及其与治疗安全性的关系。方法 18名符合DSM-IV精神分裂症诊断患者经过第1,8,38 d的固定剂量注射后,每30 d进行一次剂量可变的药物注射,按照最后3针实际给予的药物剂量分组。于试验第8,11,14,17,21,28,38,68,98,128,158,188 d采血,高效液相色谱法测定血浆中帕利哌酮浓度,临床症状在试验第1 d和188 d用PANSS评分,安全性则通过不良事件监测、生命体征监测、实验室检查以及锥体外系反应量表评估,用SPSS软件分析数据。结果17名最终完成试验的患者分为75 mg eq.(n=5)、100 mg eq.(n=9)、150 mgeq.(n=3)3组,各组的稳态血药浓度为(23.42±11.95),(24.52±12.44),(16.92±6.53)ng.mL-1,注射后的峰浓度出现在第11～18 d,平均为17 d。11例患者共出现17例次不良事件,程度均为轻中度。结论给药后,帕利哌酮棕榈酸盐各剂量组间稳态浓度无差异,但个体差异明显。药物剂量与不良反应间未见关联。
