CONCLUSIONS The control of using antibiotics must be emphasized and they should be applied in a scientific and reasonable way.The key points include the management of purchasing drugs,clinical indications and usages,supervise and news feedback,etc.All of these measures could prevent the occurrence of nosocomial infection effectively.

BACKGROUND: Direct observation of infarcted microvaseular perfusion after cerebral infarction is the most immediate evidence in evaluation of therapeutic effects.OBJECTIVE: To observe dynamic changes in flowing quality and field in cerebral ischemic area in rats so as to qualitatively and quantitatively analyze the microvascular state in pia matral encephali ischemic area and the changes of associated leukocytic flowing velocity and flowing morphology.DESIGN: Randomized controlled experiment was designed.SETTING: Department of Acupuncture and Moxibustion of General Hospital Chinese PLA.MATERIALS: The experiment was performed in Research Room of Microcirculation of General Hospital Chinese PLA, in which, 120 female Wis tar rats of 2-month old were employed and randomized into acupuncture group (36 rats), model group (36 rats), sham-operation group (36 rats) and normal group (12 rats). The first 3 groups were subdivided in 3 hours, 6hours and 24 hours groups according to the prescriptive time divisions, 12rats in each group.METHODS: In acupuncture and model groups, after abdominal anesthesia with pentobarbital sodium, the cranium was opened and the occlusion of meddle cerebral artery was performed in cerebrum with heat-coagulation method. In sham-operation group, anesthesia and cranium opening were performed, but the meddle cerebral artery was not occluded. In normal group, no any management was performed. In acupuncture group, 60 minutes after occlusion of meddle cerebral artery in cerebrum, needling was given on Renzhong (GV 26) and Neiguan (PC 6) with electric stimulation of disperse-dense wave, 4-10 Hz frequency and 0.4 V of intensity, lasting for 5 minutes. Afterwards, pecking-acupuncture technique was done on Renzhong (GV 26) to achieve strong stimulation for 10 seconds. In shamoperation and model groups, the rats were in process of grasping and fixation, but acupuncture was not applied. Vascular endotheliocyte fluorescence staining and leukocyte fluorescence tracing method were applied, in combination with microscopic video system and computer imaging analyzing system, to observe in dynamic and quantitatively the influences of acupuncture on pia matral encephali microvascular morphology, density and blood flowing velocity at 3 hours, 6 hours and 24 hours after cerebral occlusion of meddle cerebral artery.morphology, density and blood flowing state at various time divisions observed directly microscopically and vascular endotheliocyte morphology and the state of brain tissue which near the microvascular after infusion with velocity in infarcted area at various time divisions measured in quantity in each group.microvascular endotheliocytes were colored worse and more fluorescent exudation appeared. Those were better remarkably in acupuncture group ty: That in model group was lower than normal group. That at 3 hours, 6hours and 24 hours in acupuncture group was higher remarkably than model group [(6.92±0.42), (3.25±0.52) pces/visual field; (7.61 ±0.51),(3.68±0.32) pces/visual field; (8.24±0.72), (5.49±1.2) pces/visual leukocyte velocity: That in model group was lower remarkably in normal group. That at 3 hours, 6 hours and 24 hours in acupuncture group was higher remarkably than model group [(1 193±358), (600±261) μm/s;(1 112±267), (517±115) μm/s, (1 766±293), (611±291) μm/s, q=4.608.28, P ＜ 0.01].CONCLUSION: At early stage of cerebral infarction, broken blood flow is severe in artery, vein and capillary in ischemic area; the numbers of opened vessels are few, flow rate is slow down and cerebral perfusion is unsatisfactory. Acupuncture amaliorate the microcirculation perfusion state in ischemic area, increases the numbers of opened vessels and improves flowing morphology of blood cell.

Objective Based on the investigation of household drinking water in Lanzhou, the reason and difference of selecting drinking water by different households of educational and earning level were analyzed. Methods 1 000 households in Lanzhou city were chosen to fill the questionnaires, and the statistical analysis were performed. Results The tap water was chosen by 65.3% of Lanzhou households. 29.8% Lanzhou households drank barreled drinking water. The "convenience" and "price" were major concerns when Lanzhou residents chose drinking water. The acceptable price of barreled drinking water was 7.2 yuan(RMB) per barrel. The households of high income and well educated were the principal households using depth treatment water as drinking water. Residents in Lanzhou city had little concerns about quality of tap water. Conclusion The tape water was chosen by a majority of Lanzhou households as drinking water. The price was the major reason for Lanzhou residents to choose drinking water. In order to keep healthy,the residents should choose safe and healthy drinking water,and they had better clean the trough.

Objective To know the effect of hours of use of the drinking machine on drinking water quality. Methods The hours of use of the drinking machine were 1week, 2, 5, 10, 12, 36 and 60 months, the water samples collected at different hours of use was determined by routine test methods of water quality. Results The total bacteria count and nitrite in drinking water exceeded the standard limits and the two indexes increased as the hours of use of the drinking machine lasted. At the first-using of drinking-machine, the total bacteria count and coliform count exceeded the standard limits seriously. Conclusion In order to ensure the drinking water safety,water should be boiled before drinking and the drinking-water-producing factories should improve the production and management. Cleaning and disinfection of the inner components of drinking water machine should be paid more attetion to.

Objective To evaluate the effect of sleep deprivation on cognitive function in the rats undergoing propofol anesthesia.Methods Sixty healthy male Sprague Dawley rats,aged 14-18 weeks,weighing 200-250 g,were randomly assigned into 3 groups (n=20 each) using a random number table:control group (group C),propofol anesthesia group (group P),and sleep deprivation + propofol anesthesia group (group SDP).Propofol was given as a bolus of 15 mg/kg followed by an infusion of 40 mg · kg-1 · h-1 for 2 h in group P.After the rats were subjected to rapid eye movement sleep deprivation for 24 h,the rats received propofol anesthesia in group SDP.Before sleep deprivation,after sleep deprivation,and at 1,3 and 7 days after anesthesia,Morris water maze test was used to assess the learning and memory function,and the escape latency and frequency of crossing the original platform were recorded.Ten rats randomly selected from each group at 1 and 7 days after anesthesia were sacrificed,and brains were removed to observe the morphology of nerve cells in the hippocampal CA1 region (by Nissl's staining) and to detect the expression of phosphorylated Tau at Thr231 (Tau-pThr231) in the hippocampal CA1 region (by immunohistochemisty).Results Compared with group C,the escape latency was significantly prolonged,the frequency of crossing the original platform was decreased,the expression of Tau-pThr231 in the hippocampal CA1 region was up-regulated at 1 day after anesthesia in P and SDP groups (P＜0.05),especially in group SDP (P＜0.05),and there was no significant difference between the groups at the other time points (P＞0.05).The pathological changes were aggravated at 1 day after anesthesia in group SDP compared with group P,and there was no significant difference at 3 and 7 days after anesthesia between group SDP and group P.Conclusion Sleep deprivation can aggravate the transient cognitive dysfunction after propofol anesthesia,and the mechanism is related to promotion of Tau phosphorylation in the rats.
