“5．12”心理重创学生哀思传统表达方法

“5．12”灾难心理重创（PTSD）学生的心理紧急援助得到政府、学校和广大心理工作者的重视，其工作势头完全可以用“众志成城”来形容。在灾区及与受灾学生的沟通中，我们深切地感受到：在地震灾难中痛失亲人的学生的心理在紧急援助后，仍将有一部分学生长期笼罩在失去亲人的痛苦困扰之中，如不能很好调整，必将影响他们的学习生活、社会交往及人格的健康成长。     

The prevalence of dementia and Alzheimer's disease in Shanghai, China: impact of age, gender, and education

We report the prevalence rates for dementia and Alzheimer's disease (AD) obtained from a probability sample survey of 5,055 noninstitutionalized older persons in Shanghai, China. A two-stage procedure was used for case finding and case identification. A Chinese version of the Mini-Mental State Examination was used to determine cases of possible dementia. Three different cutoff points on this mental status test were used depending on the respondent's level of education. Clinical evaluations, based on functional assessments and psychiatric interview, medical and neurological examinations, three standardized mental status tests, and a selected group of psychometric tests, were made in the second stage of the study to ascertain the clinical diagnosis of dementia and AD utilizing the Diagnostic and Statistical Manual for Mental Disorders, edition 3 and National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association criteria, respectively. The prevalence rate of dementia in persons 65 years and older was 4.6%. Clinically diagnosed AD accounted for 65% of the subjects with dementia. These findings indicate that the prevalence of dementia in Shanghai is very much higher than figures published earlier for China and Japan, and at the lower part of the range of values reported for community residents in the United States and other Western countries, but less than half of that reported in the recently published survey of the elderly in East Boston. Increasing age, gender (female), and low education are each highly significant and independent risk factors for dementia. One hypothesis to explain the increased prevalence in elderly women who had received no formal education invokes the possibility of an effect of early deprivation, perhaps lowering brain "reserve," allowing the symptoms of dementia to appear at an earlier date during disease progression.     

睾丸原发性恶性淋巴瘤——附10例报道

目的报道10例睾丸原发性恶性淋巴瘤,并分析其临床表现、形态学牲及免疫表型。方法 采用HE及免疫组织化学方法,对标本切片进行染色,显微镜观察分析。结果患年龄为38～76岁,中位年龄56．25岁。临床表现主要为睾丸无痛性弥漫性肿大。病变部位：右侧5例,左侧4例,双侧1例。组织学形态均为恶性弥漫性非霍奇金淋巴瘤,免疫表型B细胞来源9例,T细胞来源1例。结论睾丸弥漫性无痛性肿大在中老年患应考虑睾丸原发性恶性淋巴瘤的可能,最后确诊要依靠病理形态学及免疫组织化学来证实。     

HNE1细胞株光动力学治疗前后形态学的动态变化

目的 探讨体外光动力学治疗（ＰＤＴ）引起鼻咽癌（ＮＰＣ）细胞死亡的作用机制。方法对鼻咽癌细胞株ＨＮＥ１体外光动力学治疗前后形态学变化进行动态观察。结果 对照组ＨＮＥ１细胞培养３ｈ,６ｈ,１２ｈ,２４ｈ和４８ｈ后细胞形态与正常培养组ＨＮＥ１细包开始变形皱缩,细胞界限模糊,细胞透光度和立体感较差,治疗２４～４８ｈ后细胞发生凋亡。结论 体外光动力学治疗对ＨＮＥ１具有明显的杀伤效应并ＨＮＥ１细胞凋亡。ＰＤ     

运动疲劳前后人体外周静脉血中性粒细胞变形性研究

本文用微吸管吸吮技术检测人疲劳运动前后中性粒细胞表面进入微吸管内的距离Ｄ（ｔ）有明显差异。提示疲劳运动会降低人中性粒细胞的变形能力,影响其与变形有关的细胞吞噬功能。     

中药肛滴在治疗消化道恶性肿瘤中的应用

小儿肾小球疾病血清微量元素测定与分析

采用原子吸收分光光度法,测定了７８ 例肾小球疾病患儿血清铜、锌、铁、镁４ 种元素。结果显示,单纯性肾病组、肾炎性肾病组、紫癜性肾病组及肾炎组血清锌均显著低于正常组（ Ｐ＜ ００５）,血清铁、镁与正常组比较无显著差异。单纯性肾病组,肾炎性肾病组血清铜显著低于正常组（ Ｐ＜ ００５）。提示血清铜、锌、铁、镁含量的变化与疾病发生和疾病状态有关。
