循证护理学在实践中的应用

循证护理的核心思想是任何护理决策都要建立在临床客观证据的基础上。护理过程中应进一步开展临床试验研究，以提供更好的护理依据。对临床护理工作中存在的同一问题有不同研究结果的情况，要用系统评价的方法进行分析，得出综合可靠的结论。作举例说明循证护理的实施方法。

C-反应蛋白水平对急性缺血性脑卒中预后影响的系统评价

目的 应用Meta分析,评价C-反应蛋白(C-reactive protein,CRP)水平对急性缺血性脑卒中预后的影响.方法 计算机检索PubMed、MEDLINE(1991-2006)、中国学术期刊全文数据库(1979-2006)等.搜集CRP水平对急性缺血性脑卒中预后影响非随机对照研究,逐篇评价纳入文献的质量,采用RevMan4.2版软件进行Meta分析.结果 共纳入7篇文献(外文4篇,中文3篇),涉及841例患者.在急性缺血性脑卒中患者中,3个月以上随访截尾时间的死亡率和再发血管事件与CRP水平相关,CRP增高组发生率比CRP正常组分别高2.71和1.81倍[OR合并分别为3.71和2.81,95%CI分别为(2.40,5.73)和(1.42,5.53)]均有统计学意义(P＜0.05);CRP测量值与缺血性脑卒中复发和死亡亦相关,在复发患者中,CRP测量值平均高于未复发者为3.52 mg/L[WMD=3.52,95%CI(-0.01,7.05)],具有一定的临床意义;在死亡患者中,CRP测量值平均高于生存者为8.02 mg/L[WMD=8.02,95%CI(5.68,10.37)],具有统计学意义(P＜0.05).结论 发病时CRP的水平可以初步评价急性缺血性脑卒中患者的预后.     

Systematic review of methods to diagnose infection in foot ulcers in diabetes.

AIM: To undertake a systematic review of the diagnostic performance of clinical examination, sample acquisition and sample analysis in infected foot ulcers in diabetes. METHODS: Nineteen electronic databases plus other sources were searched. To be included, studies had to fulfil the following criteria: (i) compare a method of clinical assessment, sample collection or sample analysis with a reference standard; (ii) recruit diabetic individuals with foot ulcers; (ii) present 2 x 2 diagnostic data. Studies were critically appraised using a 12-item checklist. RESULTS: Three eligible studies were identified, one each on clinical examination, sample collection and sample analysis. For all three, study groups were heterogeneous with respect to wound type and a small proportion of participants had foot ulcers due to diabetes. No studies identified an optimum reference standard. Other methodological problems included non-blind interpretation of tests and the time lag between index and reference tests. Individual signs or symptoms of infection did not prove to be useful tests when assessed against punch biopsy as the reference standard. The wound swab did not perform well when assessed against tissue biopsy. Semiquantitative analysis of wound swab might be a useful alternative to quantitative analysis. The limitations of these findings and their impact on recommendations from relevant clinical guidelines are discussed. CONCLUSION: Given the importance of this topic, it is surprising that only three eligible studies were identified. It was not possible to describe the optimal methods of diagnosing infection in diabetic patients with foot ulceration from the evidence identified in this systematic review.

智力残疾的适应性行为评估

适应性行为评估是智力残疾诊断与干预的必要依据。适应性行为的概念至今仍未有统一的观点，AAMR（2002）认为，适应性行为指的是概念、社会和应用3方面的技能，它的限制会影响个体的日常生活运作，进而影响其生活适应。对适应性行为进行评估的方法主要有测验法、行为观察法、功能性评估、生活质量评估和社会技能测量。无论使用什么方法进行评估，都应当以改善智力残疾个体现有状况为目的，考虑到各种评估方法的局限性，对智力残疾个体宜进行全面评估。     

Kluver-Bucy综合征

Kluver-Bucy综合征是一种较罕见的神经精神障碍引起的综合征，其特征为视觉失认、口部探索、饮食习惯改变、对视觉刺激过度注意、平静淡漠、性欲增强等，此外还有一些表现如失语、遗忘、痴呆和癫痫可能是人类所特有的。Kluver-Bucy综合征常由双侧颞叶病变引起。
