The telephone survey: a methodological strategy for obtaining information

Studies have shown that students and the general population have little knowledge about nursing schools and the nursing profession. This study investigates the extent to which a sample of the population of Brazil is aware of the existence of nursing schools, and how they have obtained this information. Data were collected by telephone interviews. The sample consisted of 326 subjects whose telephone numbers were taken from the telephone book. Analysis showed that 73% of the subjects were aware of the existence of two nursing schools in the city; however, 65.03% did not know the names of these schools. Direct communication with friends and family, as well as indirect communication by television and advertising, were the sources of information mentioned by those questioned.     

加强保健措施 降低孕产妇死亡率的试点研究

经调查河南省七县1988～04～1989～03孕产妇死亡率为136.1/10万,高于全国平均水平(94.7/10万)。从七县中选择了死亡率偏高的三个县(147.9/10万)为样本.进行厂降低农村孕产妇死亡率保健措施的研究。自1990年4月1日～1992年3月31日。在三县采取了以下保健措施:①加强基层妇幼卫生建设,特别是中心乡卫生院的建设,②整顿和完善三级保健网;③建全孕产妇系统管理制度,高危妊娠筛查,转化和转诊制度,④配备必要设备,建立联合小产院,实行定点接生。两年内孕产妇死亡率,由1989年的147.9/10万下降到67.7/10万,下降幅度为54.44%,最高达72.1%。此工作为实现2000年孕产妇死亡率下降一半的规划目标提供了依据。     

~(123)I-MIBG心肌显像预测依那普利对扩张型心肌病患者治疗效果的临床价值

目的探讨123I-MIBG心肌显像在治疗前预测依那普利对扩张型心肌病(DCM)患者治疗效果的临床价值。方法对24例DCM患者于依那普利治疗前行早期(20min)及延迟(3h)123I-MIBG心肌显像,采用心/上纵隔(H/M)比和心脏放射性洗脱率(WR)作为相对半定量计数分析,与超声心功能参数进行对比。根据123I-MI-BG心肌显像延迟相的H/M分为3组延迟H/M≥1.7为组Ⅰ,1.5<延迟H/M<1.7为组Ⅱ,延迟H/M≤1.5为组Ⅲ。组Ⅰ和组Ⅱ在平均治疗4.5个月后重复以上检查。结果治疗前3组间超声心功能参数比较均无统计学差异。治疗后组Ⅰ的左室射血分数(LVEF)和左室收缩末径(LVDs)明显改善,早期H/M和延迟H/M均明显改善(P<0.05),而WR无明显变化。治疗后组Ⅱ的延迟H/M明显改善(P<0.05),而早期H/M和WR均无明显变化,心功能参数也无改善。组Ⅰ和组Ⅱ患者均能耐受依那普利治疗,而组Ⅲ患者均不能耐受依那普利治疗。结论123I-MIBG心肌显像在治疗前预测依那普利对DCM患者的治疗效果方面有一定价值。     

自体颅骨碎片及屑修补颅骨缺损(附60例报告)

应用自体颅骨碎片及骨屑对60例在造成颅骨缺损术同时行颅骨缺损修补术。缺损面积直径最小者2cm,最大者10cm。术后随访1个月至5年,病人颅骨缺损修补处外观正常,无凹陷,触之硬,与正常颅骨处类似。6个月拍X线片示颅骨修补处类似正常颅骨形态。     

中性粒细胞的化学发光测定

用化学发光法检测粒细胞吞噬功能具有灵敏、准确、快速等优点。用我校同位素实验室LS3801型液体闪烁分析仪,全部使用国产试剂,建立了分离的中性粒细胞化学发光测定法,并对影响因素作了初步观察和探讨。实验表明,此法既可用于中性粒细胞吞噬杀菌功能机理研究,亦可用于临床监测。对糖尿病人粒细胞功能化学发光测定结果,显示了此法应用的潜力。     

Natural history of atopic dermatitis and its relationship to serum total immunoglobulin E in a population-based birth cohort study

We investigated the natural history of atopic dermatitis (AD) in a population-based birth cohort and assessed whether children at risk of visible eczema at 5 years of age can be identified from total immunoglobulin E (IgE) levels measured at 8, 12 and 18 months. AD data collected included a whole body examination for visible eczema at 49 months (4 years) and 61 months (5 years) of age and parent completed questionnaire data throughout their early lives. Children were divided into four groups based on their natural history of early AD: persistent (AD at 1, 6, 18, 30 and 42 months, n  = 34), intermittent early onset (before 18  months of age, n  = 495), intermittent late onset (18–42 months of age, n  = 273) and unaffected ( n  = 429). Visible eczema at 5 years of age was present in 12.2% (117/957) (95% confidence interval [CI] 10.1–14.3%) of the children. Levels of total IgE at 8, 12 and 18 months of age were associated with early onset of AD, but not with AD of later onset. For all four natural history groups, the geometric mean total IgE at 12 months was higher in those who subsequently had visible eczema than those who did not. However, the degree of overlap was such that total IgE at 12 months of age was a poor predictor of eczema at age five. A cutoff point of 78 kU/l had the highest positive predictive value for visible eczema at 5 years of age of 28.6%, with a sensitivity of 12% and specificity of 95%.     

第二足趾跖侧菱形皮瓣转移改形法再造拇指

目的介绍第二足趾跖侧菱形皮瓣转移改形再造拇指的方法。方法用传统方法切取第二足趾后,于第二足趾近段跖侧设计菱形皮瓣,用180°逆形转移或向远侧直接推进的方法将皮瓣嵌入第二足趾跖侧狭细处,以改善其外形。结果临床应用6例,再造拇指全部存活。术后随访3～24个月,再造拇指外形美观,感觉运动恢复满意。结论用第二足趾跖侧菱形皮瓣转移改形法再造拇指,能明显改善第二足趾的外形,使再造拇指更美观。     

卡巴胆碱对多器官功能障碍综合征小鼠脏器功能和结构的保护作用

目的:观察卡巴胆碱(carbachol,Car)对酵母多糖致多器官功能障碍综合征(MODS)小鼠多脏器功能和结构损伤的防护作用。方法:采用腹腔注射酵母多糖的方法复制小鼠MODS模型。雄性C57BL/6小鼠随机分为正常对照组(n=10),MODS 6、24、48 h组(n=30)和MODS Car 6、24、48 h防治组(n=30)。MODS组在致伤后腹腔注入生理盐水;MODS Car防治组在致伤前24 h内分3次灌胃注入卡巴胆碱。观察酵母多糖致伤后早期(48h内)动物死亡率,检测各组血丙氨酸转氨酶活性、尿素氮和肌酐水平,镜下观察致伤后48 h动物肝、肺、肾、心等脏器的组织病理学改变。结果:在酵母多糖致伤后48h内,MODS组小鼠死亡率达26.6%,MODS Car防治组的小鼠死亡率为10.0%。MODS组小鼠血浆ALT、BUN和Cr在伤后6h升高,而同时间点经卡巴胆碱预处理的小鼠血浆ALT、BUN和Cr仅略有升高,明显低于MODS组。光镜下观察发现,MODS组小鼠肝脏、肺脏、肾脏和心脏发生明显的病理改变,主要表现为脏器实质细胞浊肿、变性,间质充血、水肿和炎性细胞浸润,而卡巴胆碱防治组小鼠上述病变明显减轻。结论:预防性给予卡巴胆碱可以降低MODS急性期动物的死亡率,减轻脏器功能和结构的损伤,对急性炎症期的脏器损伤具有保护作用。
