高血压病合并脑梗死的动态血压特点

目的 :观察高血压病合并脑梗死患者的动态血压特点。方法 :对 70例高血压病合并脑梗死患者和 1 0 2例单纯高血压病患者进行 2 4h动态血压监测。结果 :84 %高血压病合并脑梗死患者血压昼夜节律消失 ,而单纯高血压病患者 5 8%消失 (P <0 .0 1 ) ;高血压病合并脑梗死组 85 %出现晨峰 ,而单纯高血压病组 5 5 %出现晨峰 (P <0 .0 1 )。结论 :血压的昼夜变化和晨峰与高血压病合并脑梗死密切相关。高血压病合并脑梗死患者晨峰明显增加 ,昼夜节律消失明显     

夜间护理纠纷的常见原因及防范对策

针对夜间护理特殊性，分析导致护理纠纷的常见原因，包括抢救不到位，患不能理解夜间护士的护理行为．服务态度问题等。提出护士应增加法制观念，加强体质锻炼，强化服务意识，严格执行诊疗护理规范、常规，落实各项规章制度，以减少护患纠纷。     

东北边境地区吸血蠓的调查研究

1980～1988年在东北边境的漠河、珲春县等10个县区采获吸血蠓2属37种,其中发现4个新种和4个国内新记录。不显库蠓(35.7％)和刺螯库蠓(34.9％)为优势蠓种。不同生境、场所和季节的蠓种组成有所不同。灰黑库蠓、淡角库蠓和端斑库蠓在整个活动季节均只出现一次高峰,而不显库蠓、刺螫库蠓和兴安库蠓在整个活动季节均出现两次高峰。刺螫库蠓的活动季节最长,为11旬,端斑库蠓最短,仅为5旬。刺螫库蠓、不显库蠓、兴安库蠓和灰黑库蠓在昼夜24小时均出现晨、昏两次活动高峰,而边缘库蠓只在凌晨出现一次晨峰。     

Depression, Night Terrors, and Insomnia Associated With Long-Term Intrathecal Clonidine Therapy

Abstract:   Intraspinal clonidine is an effective adjunct to intrathecal/epidural opioid administration. We report a case of neuropathic pain treated with intraspinal analgesics in which depression, insomnia, and night terrors developed in association with intraspinal clonidine.     

Large rod-like photopic signals in a possible new form of congenital night blindness

A 10-year-old Persian girl has symptoms of congenital stationary night blindness and some drusen-like lesions in the region of the vascular arcades. Her electroretinogram shows no rod response to a weak stimulus, but a large (475 V) slow scotopic response to a strong stimulus that is unchanged by photopic conditions (15 F1 background illumination). However, the response to flicker had the typical (smaller) amplitude of a cone signal. This may represent a new form of night blindness in which rod sensitivity is reduced so that there is no vision under dim conditions but rod function still persists under photopic conditions.     

The effects of bright light treatment on subjective and objective sleepiness during three consecutive night shifts among hospital nurses – a counter-balanced placebo-controlled crossover study

Objectives:The objective was to investigate effects of timed bright light treatment on subjective and objective measures of sleepiness during three consecutive night shifts among hospital nurses.Methods:Thirty-five nurses were exposed to bright light (10,000 lux) and red dim light (100 lux) during three consecutive night shifts in a counter-balanced crossover trial lasting nine days, which included three days before and three days after the three night shifts. Light exposure for 30 minutes was scheduled between 02:00–03:00 hours on night 1, and thereafter delayed by one hour per night in order to delay the circadian rhythm. Subjective sleepiness was measured daily (heavy eyelids, reduced performance) and every second hour while awake (Karolinska Sleepiness Scale, KSS). Objective sleepiness (Psychomotor Vigilance Task, PVT) was measured at 05:00 hours during each night shift. Beyond nocturnal light exposure on the night shifts, no behavioral restrictions or recommendations were given at or off work.Results:Bright light treatment significantly reduced heavy eyelids during night shifts. However, results on KSS and PVT were unaffected by bright light. There were no differences in subjective sleepiness during the three days following the night shifts.Conclusions:This bright light treatment protocol did not convincingly reduce sleepiness among nurses during three consecutive night shifts. Nor did bright light impede the readaptation back to a day-oriented rhythm following the night shift period. Too few consecutive night shifts, inappropriate timing of light, and possible use of other countermeasures are among the explanations for the limited effects of bright light in the present study.     

充血性心力衰竭患者动态血压的变化及意义

目的 探讨慢性充血性心力衰竭（ＣＨＦ）患者２４ｈ动态血压的变化及意义。方法 将５７例ＣＨＦ患者按心功能的受损程度（ＮＹＨＡ分组）分为Ａ组（１７例,心功能Ⅱ组）、Ｂ组（１９例、心功能Ⅲ级）和Ｃ组（２１例,心功能Ⅳ级）;根据病因的不同,分为Ｄ组（１６例,扩张型心肌病）和Ｅ组（４１例,非扩张型心肌病）;全部患者行２４ｈ动态血压（２４ｈ ＡＢＰ）检查,比较Ａ,Ｂ,Ｃ三组及Ｄ、Ｃ两组之间平均收缩压、夜间平均收缩压下降率（ｎｓＢＰＲ）及２４ｈ平均收缩压变异率（２４ｈ ｓＢＰＶ）的差异。结果 Ｃ组的平均收缩压较Ａ组和Ｂ组略低,但三组之间差异无显著性（Ｐ〉０．０５）;Ｄ组的平均收缩压显著低于Ｅ组（Ｐ〈０．０５）。Ａ,Ｂ,Ｃ３组的ｎｓＢＰＲ减弱或消失,分别占５８．８％,８８．３％和９５．２％,Ａ组与Ｂ,Ｃ,组的平均收缩压显著低于
