Analysis of brain-stem auditory evoked potential and visual evoked potential in patients with Parkinson disease

INTRODUCTION The exact cause of Parkinson disease (PD) has not been known yet[1]. The overwhelming progress had been made in the treatment and pathogenesis of PD in recent 30 years, especially 10 years[2]. But it is still no way now to prevent or postpone…     

急性脑梗死血清C-反应蛋白的临床分析

目的观察急性脑梗死患者血清CRP在发病中的作用及临床意义。方法采用免疫比浊法对60例急性脑梗死患者的血清CRP水平进行动态观察（病程第1．7及14天），并与45例健康人进行比较。结果急性脑梗死患者血清CRP从病程第1天即升高（P〈0．01），至第7天达高峰，以后降低；重型患者明显高于轻、中型患者。结论血清CRP可能在急性脑梗死的发生、发展中起一定作用，并与病情严重程度呈正相关。     

全程分期式健康教育对Miles术后患者生活质量的影响

目的探讨全程分期式健康教育对Miles术患者生活质量的影响.方法将80例行Miles术的直肠癌患者随机分为观察组与对照组各40例.观察组采用全程分期式健康教育,对照组采用传统的手术前后宣教.两组均在出院前,出院后1、3、6个月发放Miles术患者生活质量问卷,在出院前发放护理工作满意度调查表进行调查.结果观察组出院前自理能力、造口情况、心理状况及护理工作满意度显著优于对照组(P＜0.05,P＜0.01),出院时间显著缩短(P＜0.05);出院后观察组自理能力、造口情况等及生活质量总分均显著优于对照组(P＜0.05,P＜0.01).结论全程分期式健康教育能有效提高Miles术患者的近期和远期生活质量.     

儿童语言发展迟缓成因的个案特征

目的:关注幼儿的早期语言教育,寻找语言发育迟缓成因。方法:采用访谈、跟踪观察的方式了解语言发育迟缓儿童语言发育现状,并对该病成因进行分析。结果:复杂的语言环境、内心的自我封闭以及父母不合理的教养态度是导致该儿童语言发展迟缓的主要原因。结论:单一的语言环境有利于该儿童语言的发展。     

采血者针刺伤的调查及危险因素分析

针刺伤在采血工作中经常发生，其危害大，后果严重，一般情况下还没有引起人们足够的重视。我国是肝炎的高流行区，近年来艾滋病在我国的发病率呈倍增的趋势。血液污染的针刺伤是导致血站采血人员发生血源性传染病最主要的职业因素。作者从实际工作出发，收集相关资料，系统的阐述了针刺伤的发生因素及预防措施等，并结合相关理论提出了一系列的措施和建议。     

前置胎盘孕妇恐惧心理观察及护理

目的观察前置胎盘孕妇的恐惧心理反应，做好前置胎盘孕妇的心理护理。方法由孕妇自行填写CES-D和SA2量表，进行统计学分析。结果70．2％的前置胎盘孕妇具有恐惧心理。结论在妊娠过程应提高孕妇认知水平，加强心理护理，有助于她们顺利渡过妊娠期。     

变温培养对泰乐菌素发酵的影响

在泰乐菌素发酵过程中的不同阶段采用不同的培养温度,通过实验考察其对泰乐菌素发酵的影响。实验结果表明,变温培养的发酵水平要高于其它恒温培养的发酵水平。     

初次吸毒者与复吸者戒毒期间生活质量比较

目的:了解包头市初次吸毒者与复吸者戒毒期间的生活质量。方法:用QOL-DA2.0量表对戒毒人员的生活质量进行调查。结果:初次吸毒者与复吸者各纬度进行t检验显示躯体功能纬度(t=10.51)、心理功能纬度(t=5.94)、症状及毒副作用纬度(t=6.41)、社会功能纬度(t=10.47)和总分(t=10.48)均有统计学意义(P<0.001),表明戒毒期间初次吸毒者的生活质量高于复吸者。结论:在戒毒期间初次吸毒者的生活质量较复吸者易改善。     

BMP-2 gene polymorphisms and osteoporosis: the Rotterdam Study.

After reported associations of variations in the BMP-2 gene with osteoporosis in small populations, we studied the association of the BMP-2 gene polymorphisms Ser37Ala and Arg190Ser with osteoporosis in 6353 men and women from the Rotterdam Study. We did not observe an association of these variants with BMD, bone loss, hip structural analysis parameters, and fracture risk. INTRODUCTION: Bone morphogenetic protein 2 (BMP-2) plays a role in osteoblast differentiation. BMP-2 gene variation has previously been associated with osteoporosis in various small populations, but current evidence remains inconclusive about the exact association with osteoporosis. Therefore, we studied the association of two polymorphisms located in the BMP-2 gene (Ser37Ala and Arg190Ser) and haplotypes defined by these polymorphisms with BMD, rates of bone loss, parameters of hip structural analysis (HSA), and fractures in the Rotterdam Study, a large prospective cohort study of diseases in the elderly. MATERIALS AND METHODS: Databases were searched for polymorphisms and haplotype blocks in the BMP-2 gene region. Allele frequencies for Ser37Ala and Arg190Ser were determined in 60 blacks and 110 Chinese from Coriell panels. Genotype data on Ser37Ala and Arg190Ser were available for 6353 individuals from the Rotterdam Study population. Haplotype alleles defined by Ser37Ala and Arg190Ser were inferred using PHASE software. Genotype and haplotype analyses for BMD (measured at the lumbar spine and femoral neck), bone loss per year (measured at the femoral neck), and HSA were performed using AN(C)OVA. Fractures were analyzed using a Cox proportional-hazards model and logistic regression. All outcomes were adjusted for age, height, and weight. RESULTS: Allele frequencies were 2.5% for Ala37 and 40.2% for Ser190, whereas haplotype allele frequencies were 57.28% (Ser37Arg190), 40.19% (Ser37Ser190), 2.50% (Ala37Arg190), and 0.02% (Ala37Ser190). For BMD, bone loss, HSA outcomes, and (incident) fractures, no differences could be seen between genotype and haplotype groups. Conclusions: In this large population-based cohort of Dutch whites, we conclude that the BMP-2 Ser37Ala and Arg190Ser polymorphisms or haplotypes thereof are not associated with parameters of osteoporosis.     

后牙两段式可摘局部义齿的设计与制作
