[目的]探讨时辰穴位按摩对卒中合并便秘病人的护理效果。[方法]根据中医经络、时辰学说选择有通便功效的辰时,即07:00～09:00为30例卒中合并便秘的病人进行穴位按摩。[结果]30例病人中,治愈12例,显效9例,好转8例,无效1例,总有效率为96.67%。[结论]时辰穴位按摩法可促进血液运行,增加对穴位的刺激作用,通便效果较好。     

卒中急性期病人中医综合康复护理效果观察

[目的]探讨中医综合康复护理对卒中急性期病人神经功能缺损及日常生活能力（ADL）的影响。[方法]选择2004年9月-2006年9月在3家协作医院住院的卒中急性期238例病人为研究对象，随机分为实验组和对照组，两组药物治疗基本相同。实验组按中医综合康复护理方案进行护理．对照组采用卒中护理常规进行护理。对入选的病人在入院第1周内和4周后进行神经功能缺损及ADL的评定。[结果]4周后实验组在临床神经功能缺损、ADL等方面明显优于对照组，差异有统计学意义（P〈0．01）。[结论]中医综合康复护理可促进肢体的功能恢复，提高病人的ADL。     

Effects of residence and race on burden of travel for care: cross sectional analysis of the 2001 US National Household Travel Survey

Background  

Travel burden is a key element in conceptualizing geographic access to health care. Prior research has shown that both rural and minority populations bear disproportionate travel burdens. However, many studies are limited to specific types of patient or specific locales. The purpose of our study was to quantify geographic and race-based differences in distance traveled and time spent in travel for medical/dental care using representative national data.     

一起幼儿园内空肠弯曲菌高感染情况的调查

作者报道了一起幼儿园内空肠弯曲菌高感染的传播。该幼儿园儿童空肠弯曲菌阳性率为23.0％(43/187)。腹泻病例空肠弯曲菌阳性率为18.6％(8/43),健康儿童带菌率为24.3％(35/144)。同期另一幼儿园健康儿童和门诊非腹泻患儿带菌率分别为11.3％(27/238)和7.5％(15/201),三者间差异显著(P<0.005)。通过流行病学调查及菌株的生物分型表明,传染源可能是两名患空肠弯曲菌肠炎的炊事员,他们与儿童的菌株为同一生物型。其传播可能是通过污染的食物或人与人接触而引起的。     

Flow cytometric analysis of NIH/3T3 cells treated with extract of Aspergillus versicolor

The effect of extract of Aspergillus versicolor, isolated from the gastric juice of patients with chronic gastric diseases in high incidence area of stomach cancer, on NIH/3T3 cells was analysed by flow cytometer. The results showed that the distribution of cell numbers in S phase and G2M phase of cell cycle, the average DNA content and proliferation index of cells treated with Aspergillus versicolor extract were significantly increased.     

Neural network models for the gaze shift system in the superior colliculus and cerebellum.

We investigate the role that the superior colliculus (SC) and the cerebellum might play in generating gaze shifts. The discharge of cells in the intermediate layers of the SC is tightly linked to the occurrence of saccades. Many studies have demonstrated that the cerebellum is involved in both eye and head movements. When the head is unrestrained, large amplitude gaze shifts are composed of coordinated eye and head movements. In this study, we propose that the gaze saccades system is controlled by a feedback loop between the SC and the cerebellum. The SC only encodes retinal coordinates and controls the eye displacement (to move the fovea to the target), while the cerebellum deals with the gaze programming and controls the head displacement. When a target appears in space, the buildup cells within the SC decode the target signal in the retina before the saccade onset, and input the signal of the gaze displacement to the cerebellum. The cells in the cerebellum vermis encode the initial position of the eye in the orbit. The gaze displacement is decomposed into the head amplitude and the eye amplitude within the cerebellum. There are two output signals from the cerebellum. One signal controls the head movement. The other is projected back to the SC, and forms a component of the saccade vector to control the eye movement. The sum of the vectors provided by the cerebellum and the vector provided by the burst cells in the SC indicates the direction and the amplitude of the desired movement of the eye during the saccade. We propose a cerebellum model to predict the displacements of the eye and head under the condition that the position of the target signal in the retina and the initial position of the eye in the orbit are known. The results from the model are close to that observed physiologically. We conclude that before gaze shift onset, the cerebellum may play an important role in decomposing the gaze displacement into an eye amplitude and head amplitude signal.     

急性心肌梗塞静脉溶栓治疗冠脉再通者早期ST段再抬高的临床意义

急性心肌梗塞早期静脉溶栓治疗后，一些溶栓再通患者中，可见早期降低的ＳＴ段再度出现抬高现象。本文回顾溶栓成功者８１例，其中早期出现ＳＴ段再度抬高者２１例（占３５％），与ＳＴ段非再度抬高者相比，ＣＰＫ、ＣＰＫ－ＭＢ峰值，心功能及院内死亡率等无显著差异。笔者认为，此现象也为再通的标志之一。因此，急性心肌梗塞溶栓治疗的早期连续监测心电图对确认再通与否非常重要
