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.     

β-淀粉样前体蛋白第二、三外显子删除突变抑制β-淀粉样蛋白分泌

目的 :观察 β 淀粉样前体蛋白第二、三外显子编码结构域对培养的人神经纤维母细胞瘤细胞系 (SH SY5Y)生长代谢和 β淀粉样蛋白 (Aβ)分泌的影响。 方法 :利用重组DNA技术 ,构建 pcDNA3.1APP695和删除第二、三外显子的pcDNA3.1ΔAPP695质粒 ,用脂质体转染法将其转入SH SY5Y细胞系 ,用 0 .6 g·L-1G4 18筛选获得稳定表达外源基因的细胞系 ,采用MTT法分析对细胞增殖的影响 ,用免疫沉淀Westernblot分析细胞培养液中Aβ的含量。结果 :成功构建了APP695cDNA和删除第二、三外显子的ΔAPP695cDNA的真核表达载体 ,转染SH SY5Y细胞系后 ,Westernblot证实外源基因得到表达 ,MTT分析结果显示删除第二、三外显子的ΔAPP695cDNA未对细胞产生明显的抑制增殖作用 ,免疫沉淀Westernblot分析表明 ,与转染全长APP695cDNA细胞相比 ,转染ΔAPP695cDNA细胞Aβ分泌显著减少。 结论 :APP695第二、三外显子编码结构域删除后抑制了Aβ的生成 ,对探讨Aβ分子前体水解加工生成Aβ的关系有重要意义     

迟发性运动障碍患者血清泌乳素浓度分析

目的:对比迟发性运动障碍(TD)、非TD(TD-)精神分裂症患者、正常对照血清泌乳素(PRL)水平,探索TD可能的病理生理机制。方法:运用放射免疫(RIA)法,测定性别比、年龄、病程、发病年龄、住院次数、目前治疗等匹配的46例TD、TD-患者及性别比、年龄与TD、TD-患者匹配的正常对照44人血清泌乳素(PRL)浓度,对三组血清PRL水平运用非参数检验进行比较;并对TD组患者异常不自主运动量表(AIMS) 各项分总和与血清PRL水平进行线性回归分析。结果:三组血清PRL水平(正常组:617±358μIU/ml,TD-组: 913±602μIU/ml,TD组:1277±1011μIU/ml)间存在显著差异(P<0.05);AIMS各项分和与血清PRL水平的相关系数为0.136(P>0.05),无明显相关性。结论:TD患者比TD-患者、正常人血清泌乳素水平升高,TD可能并非单纯由多巴胺受体增敏所致。     

精神卫生从业人员的社会安全保障现状及对策

中国是一个以精神疾病低治疗率为特点的精神卫生资源匮乏的发展中国家.根据卫生部的统计数据[1],中国13亿人口中,患有严重精神疾病的患者达1600多万,患有不同程度精神或心理障碍需要专业人员干预的达到1.9亿人.     

在医院发展中需要注意的若干重要因素

当前，医院如何适应新的历史环境，如何保持医院的可持续发展，如何克服医院的发展劣势，借助社会发展动力，壮大我院自身发展实力，创造并保持医院的发展优势，这是每一个医院管理者必须思考的重要课题。     

柴胡桃仁汤对迟发性运动障碍模型大鼠的治疗作用

目的观察柴胡桃仁汤对迟发性运动障碍(tardive dyskinesia,TD)大鼠模型行为及血清超氧化物歧化酶(superoxide dismutase,SOD)活力、脂质过氧化代谢物丙二醛水平变化,探讨TD可能的病理生理机制.方法将24只雄性Sprague-Dawley(SD)大鼠随机分为空白、模型、治疗四组,每组8只,分别予腹腔注射生理盐水+第5周始灌胃生理盐水、腹腔注射氟哌啶醇+第5周始灌胃生理盐水、腹腔注射氟哌啶醇+第5周始灌胃柴胡桃仁汤处理,共9周;每周末观察大鼠口部异常运动,进行评分.研究结束时取静脉血,分离血清,测定血清超SOD活力、及丙二醛水平.结果腹腔注射氟哌啶醇使SD大鼠口部异常运动增加明显,第5周达峰值;柴胡桃仁汤可使TD模型大鼠口周异常运动评分下降,减分为12.0±9.9,与TD组(0.6+4.2)相比,差异有显著性(u=5.0,P＜0.05);TD组大鼠血清SOD活力(kat/L)明显降低(5.4±0.7),丙二醛水平(kat/L)显著升高(20.4±6.0),柴胡桃仁汤可缓解这一改变(SOD6.5±0.3,丙二醛7.7±3.2),而且差异均有显著性(P＜0.01).可用于制作TD动物模型;而可使这些行为异常显著缓解(P＜0.05);与模型组比较,治疗组血清SOD活力升高,丙二醛水平下降,差异有显著性意义(P＜0.01).结论柴胡桃仁汤通过阻制氧化损伤,有效缓解TD模型大鼠口周异常运动,氧化应激在TD发生过程中起重要作用.
