使用便携式微量输液泵持续输注氟尿嘧啶的临床观察及护理

目的：探讨使用便携式微量输液泵在肿瘤化疗中持续输注氟尿嘧啶的应用效果。方法：选取我科2006年3月-2008年7月96例癌症化疗病人按入院先后顺序分为对照组和实验组,每组48例。对照组采用传统的化疗方式,采用浅静脉留置针直接从外周静脉输注氟尿嘧啶（5-Fu）连续5天,每天维持6-8小时。实验组采用浅静脉留置针连接便携式微量输液泵持续泵入氟尿嘧啶（5-Fu）120h～135h,两组均以21天为1个周期,观察两组病人化疗毒副反应发生情况。结果：实验组化疗毒副反应发生率明显低于对照组,平均住院时间明显缩短,两组比较差异有统计学意义（P〈0.01）。结论：使用便携式微量输液泵持续泵入氟尿嘧啶能减轻病人的毒副反应,缩短住院时间,提高肿瘤病人生活质量,有效减轻护士的工作负担。     

广西边远少数民族学生体型及体质量指数3年追踪**

背景: 前期研究表明广西18~22岁少数民族学生体质量偏轻。 目的：拟进一步了解广西2645名少数民族学生体型及体质健康状况，寻找影响的关联因子。 设计、时间及地点：追踪调查，于2004-12/2007-12在广西民族大学完成。 对象：广西民族大学2003/2005三次体质健康测试的全体学生2 645人。男1 337人，女1308人，年龄为18~20岁，共15个民族。 方法：根据2003年教育部、体育总局《学生体质健康标准（试行方案）》和实施方法分为形态指标、技能指标和身体素质指标3大类。对2 645名少数民族身体机能与体质量指数变化的跟踪调查。 主要观察指标：身高、体质量、肺活量、立定跳远、坐位体前屈、体质量指数。 结果：①广西民族大学2003级学生大学3年期间男生身高、体质量增长率比全国同期多2.45%，身体形态发育正处于高峰期，女生成偏瘦型体型，身体形态发育情况总体欠佳。②男女学生在刚入校时肺活量机能较差，远远低于同期全国平均水平。3年后男生肺活量增长率为11.55%、女生肺活量增长率为27.72%，分别高于全国同期肺活量增长率。③坐位体前屈机能高于同期全国平均水平，男生呈逐年上升趋势，同期全国男性呈下降趋势；同期全国乡村女生均呈逐年上升趋势。④立定跳远机能提高较大，3年后增长率为18.15%，明显高于全国同期立定跳远增长率水平的2.61%。女生立定跳远机能总体不如全国同期水平。⑤体质量指数总体与同期全国乡村男女学生体质量指数比较稍低一些(P < 0.01)。 结论：2 645名少数民族学生发育正处于高峰期；肺活量机能不及全国同期平均水平。男女体质量指数分布有所不同，体质量偏轻者女生多于男生，表明学生营养状况总体欠佳。     

Preliminary Findings from a Brief,Peer-Led Safer Sex Intervention for College Students Living in Residence Halls

The purpose of this study was to evaluate a single-session peer-led safer sex intervention, based on the Information-Motivation-Behavioral Skills theoretical model, for college students residing in campus residence halls. Participants (N = 108) were assigned to either an hour long control or 5-module intervention session. Compared to the control condition, the intervention increased participants’ information and women’s subjective norms about preventative behavior. Both the control and intervention sessions increased intentions to perform preventative behaviors (e.g., keep condoms available). These preliminary results suggest that this intervention is promising for increasing constructs associated with safer sexual behavior and could easily be implemented by residence hall staff.     

A Preliminary Study of the Population-Adjusted Effectiveness of Substance Abuse Prevention Programming: Towards Making IOM Program Types Comparable

The Institute of Medicine distinguishes between programs based on who is targeted: the entire population (universal), those at risk (selective), or persons exhibiting the early stages of use or related problem behavior (indicated). Evaluations suggest that although universal programs can be effective in reducing and preventing substance use, selective and indicated programs are both more effective and have greater cost-benefit ratios. This paper tests these assumptions by comparing the impact of these program types in reducing and preventing substance use at the individual level (i.e., those exposed to intervention services) and in the population (i.e., those exposed and not exposed to intervention services). A meta-analysis was performed on 43 studies of 25 programs to examine program comparability across IOM categories. When examining unadjusted effect sizes at the individual level, universal programs were modestly more successful in reducing tobacco use, but selective and indicated programs were modestly more successful in reducing alcohol and marijuana use. When adjusted to the population level, the average effect sizes for selective and indicated programs were reduced by approximately half. At the population level, universal programs were more successful in reducing tobacco and marijuana use and selective and indicated programs were more successful in reducing alcohol use. Editors’ Strategic Implications: The authors’ focus on the public health value of a prevention strategy is compelling and provides a model for analyses of other strategies and content areas.     

Chronic fatigue of the small enterprise workers participating in an occupational health checkup center in southern Taiwan

Purpose  There has been increasing interest in the occupational health of workers in small enterprises, especially in developing countries. This study examines the association between psychosocial job characteristics and fatigue, and attempts to identify risk factors for fatigue among workers of small enterprises in southern Taiwan. Methods  A structured questionnaire was administered to workers receiving regular health examinations between August 2005 and January 2006. The questionnaire collected demographic information and data on working conditions, personal health status and life styles. It also collected information on psychosocial job characteristics, fatigue and psychological distress using three instruments. Results  A total of 647 workers with mean age of 43.7 were completed. Probable fatigue was found in 34.6% of the sample. Fatigue was found by multiple logistic regressions to be associated with the lack of exercise, working in shifts, depression score and lack of social support at workplace. Conclusions  This study found associations between life style, psychosocial job characteristics and fatigue. Because the high prevalence of probable fatigue was found in such small enterprises, the authors suggest that a short interview with some quick questionnaires in health checkup for these small enterprise workers are helpful to early detect psychosocial and fatigue problems.     

空腹血糖——急性心肌梗死患者早期死亡的独立预测因子

目的研究急性心肌梗死(AMI)患者空腹血糖的预后价值。方法本研究入选257例无糖尿病病史AMI患者。测量患者入院时血糖(AG)和禁食至少8h后的血糖(FG)。随访患者30d,分析AG和FG与患者预后之间的关系。结果共24(9.3%)例无糖尿病病史患者在AMI后30d内死亡。FG正常组死亡2例(1.5%),FG升高者的第一、第二、第三个三分位数组分别死亡4例(9.8%)、5例(12.2%)、13例(31%)。和FG正常组患者相比,校正后的30d死亡的相对危险比(OR)随FG三分位数的增加而增加,第一、第二和第三个三分位数组分别为:2.5(95%CI,0.71～8.5;P=0.011),8.6(95%CI,3.2～23.5;P=0.0005),12.7(95%CI,4.5～36.4;P<0.0003)。同FG和AG都正常的患者相比,AG升高FG正常预测患者30d死亡的OR为0.69(95%CI,0.25～3.80;P=0.59);AG正常FG升高者为3.6(95%CI,2.1～11.5;P=0.04);FG和AG都升高者为10.6(95%CI,4.3～25.6;P<0.0001)。镶嵌模型的比较显示AG并不能增加FG模型预测30d死亡(2=5.2,3df,P=0.20)或预测30d死亡和心力衰竭(2=4.8,3df,P=0.31)的价值。相反,FG却能增加AG模型预测30d死亡(2=24.5,3df,P=0.0001)或预测30d死亡和心力衰竭(2=24.7,3df,P=0.0001)的价值。结论无糖尿病病史AMI患者30d死亡率随AG和FG浓度的增加而增加,FG比AG的预测价值更大。     

不同剂量和疗程伐昔洛韦治疗带状疱疹的多中心随机双盲对照研究

目的：比较不同剂量和疗程伐昔洛韦治疗带状疱疹的疗效和安全性。方法：选择带状疱疹患者为研究对象，采用多中心、随机、双盲、对照的临床试验。试验组患者采用伐昔洛韦1000mg每日3次口服，共服7d；对照组患者采用伐昔洛韦300mg每日2次口服，共服10d。用药后第3、6和10天观察疗效和不良反应。结果：共入组128例，全分析集（FAS）分析128例，符合方案集（PPS）分析118例。治疗后第3、6和10天，试验组和对照组患者的症状、体征积分下降值及有效率比较差异无统计学意义（P〉0．05）；疼痛视觉模拟评分法（visnal analogue scale，VAS）值比较，两组间差异无统计学意义（P〉0．05），但入组时疼痛VAS值≥8的患者，FAS集分析显示，在治疗后第6、10天VAS值下降两组均存在统计学差异（P〈0．05）；PPS集分析显示治疗后第10天VAS值下降，两组间存在统计学差异俨〈0．05）。试验组和对照组不良反应发生率分别为17．18％和12．50％．主要为嗜睡和恶心。结论：增加伐昔洛韦用量治疗带状疱疹安全、有效，与较低剂量伐昔洛韦组相比，对疼痛程度较严重的患者能更显著地减轻疼痛。     

肥胖类型与脑卒中亚型的相关性研究

目的探讨肥胖类型与脑卒中亚型的相关性。方法将573例急性脑卒中患者分为脑出血组126例,脑梗死组447例,脑梗死组再分为脑血栓形成组(215例)和腔隙性脑梗死组(232例),另外选择277例无脑卒中者为对照组。测量腰围、臀围和体重,计算体重指数和腰臀比(WHR),分析肥胖参数与脑卒中各亚组的关系。结果脑卒中各亚组与对照组肥胖发生率差异无显著性意义(P>0.05);各组WHR明显大于对照组(P<0.05)。WHR增大明显增加脑卒中各亚组的危险性(P<0.05);女性腹围增大患腔隙性脑梗死危险性升高(P<0.05);男性体重增加患脑出血的危险性升高(P<0.01)。结论腹型肥胖是脑出血、脑血栓形成和腔隙性脑梗死的危险因素之一。
