优化商品陈列 刷新销售业绩

研究表明：商品陈列面的大小变化、化妆品陈列的高低变化和化妆品的陈列时间等均会影响化妆品店的销售额。首先，商品陈列面的大小变化会引起销售额的变化。如由4个货位减少到2个货位，销售额锐减48％；由3个货位减少到1个货位，销售额锐减68％；由2个货位增加到4个货位，销售额增加40％。所以，在化妆品店的商品陈列中，要加大购买频率较高品种的陈列面，并以大陈列面形成聚焦点，刺激顾客购买。     

Changes in T .lymphocyte subsets after severe traumatic brain inJury

BACKGROUND： Besides local changes of cranial parenchymal cells, hemorrhage, etc., severe traumatic brain injuries also cause the changes of total body fluid and various functions, and the changes of lymphocytes and T lymphocyte subsets should be paid more attention to. OBJECTIVE： To reveal the changing laws of T lymphocyte subsets after severe traumatic brain injury, and compare with mild to moderate brain injury. DESIGN： A comparative observation. SETTINGS： Department of Neurosurgery, Longgang District Buji People＇s Hospital of Shenzhen City; Central Laboratory of Shenzhen Hospital of Prevention and Cure for Chronic Disease. PARTICIPANTS： All the subjects were selected from the Department of Neurosurgery, Longgang District Buji People＇s Hospital of Shenzhen City from August 2002 to August 2005. Thirty patients with severe brain injury, whose Glasgow coma score （GCS） was ≤ 8 points, were taken as the experimental group, including 21 males and 9 females, aging 16 - 62 years. Meanwhile, 30 patients with mild traumatic brain injury were taken as the control group （GCS ranged 14- 15 points）, including 18 males and 12 females, aging 15 -58 years. All the subjects were in admission at 6 hours after injury, without disease of major organs before injury Informed consents were obtained from all the patients or their relatives. METHODS： （1） The T lymphocytes and the subsets in peripheral blood were detected with immunofluorescent tricolor flow cytometry at l, 3, 7 and 14 days after injury in both groups. （2） The conditions of pulmonary infections were observed at 4 days after injury. The differences of measurement data were compared with the t test. MAIN OUTCOME MEASURES： Changes of T lymphocytes subsets at 1 - 14 days after severe and mild or moderate traumatic injury. RESULTS： Finally, 28 and 25 patients with mild to moderate traumatic brain injury, whereas 25 and 21 patients with severe traumatic brain injury were analyzed at 7 and 14 days respectively, and the missed ones died due to the development of disease. （1） Changes of T lymphocyte subsets： At 1 and 3 days after injury, CD3, CD4, CD8, CD4/CD8 began to decrease, whereas CD8 increased in the experimental group, which were very significantly different from those in the control group （t =2.77 - 3.26, P 〈 0.01）, and began to recover at 7 days, which were significantly different from those in the control group （t = 2.06 - 2.24, P 〈 0.05）, and generally recovered to the normal levels at 14 days （P 〉 0.05）. （2） Conditions of pulmonary infections： At 4 days after injury, the rate of pulmonary infection was significantly different between the experimental group and control group [73% （22/30）, 0, x2=37.29, P 〈 0.01]. CONCLUSION： Patients with severe traumatic brain injury suffer from damages of cellular immune function at early period （within 7 days）, and they are easily to be accompanied by pulmonary infections.     

谈足疗的神奇功效

足疗是我国传统医学的宝贵遗产之一,它是在中医理论的指导下,运用各种特定或变化的手法在足部反射区进行有效的刺激,通过这种良性的物理刺激缓解人体的紧张状态,促进足部经络气血运行,进而调节全身各系统的生理变化以达到治疗、预防、保健等目的的保健治病方法。

冠内附着体的临床应用及力学分析

附着体在口腔修复中的应用已有一百多年的历史,随着科学技术的进步和发展,精密附着体逐渐走向成熟和商品化,使用精密附着体替代常规固位体,可以增进美观,改善基牙的应力分布,增强义齿稳定性,提高咀嚼效率[1]。目前附着体已应用于固定义齿、可摘义齿、固定可摘联合义齿、覆盖义齿和种植义齿上部结构中,丰富了义齿设计形式,为医师和患者提供了选择余地。附着体种类繁多,分类方法不一,Burns[2] 等的阐述较为系统,其中主要分类为:1.根据制作方法及精密程度分为精密附着体(precisionattachment)和半精密附着体(semipresicionattachment)。2.根据附着体与基牙的关系分为:冠内附着体(intracoronalattachment)和冠外附着体(extracoronalattachment)。3.根据附着体受力时是否运动分为:刚性附着体(rigidattachment)和弹性附着体(resilientattachment)。4.根据附着体的形状分为:栓体栓道(key-keyway)附着体;球窝(ballsocket)附着体;球帽(ballcap)附着体即摁扣式(snapfastener)附着体...     

人工髋关节置换术后脂肪栓塞综合征的观察与护理

笔者报道人工髋关节置换术后脂肪栓塞综合征的护理措施认为重视氧饱和度及动脉血氧分压监测，注意观察中枢神经系统症状和呼吸系统症状，及时发现并纠止低氧血症，对不同的病人制定不同护理方案，严密观察病情，及时掌握病情变化：是护理的关键。     

骨水泥填充对人工关节假体置入后应力状态的影响

本研究应用光弹技术对骨水泥填充后人工关节假体的应力状态进行了观测，结果表明骨水泥固结长度增加可降低假体内侧内应力，但固结假体柄尖部则反而使假体柄中上段应力增大，易生产假体柄疲劳断裂。     

Functional Maturation of Neuroendocrine Gonadal Axis is Altered by Specific Phase Relations of Circadian Neurotransmitter Activity in Japanese Quail

The preset study was designed to ascertain the effects of temporal relationship of circadian neural oscillations on puberty attainment and reproductive growth of Japances Quail,Coturnix coturnix japonica,Serotonin and dopamine precursors(5-hydroxytryptophan,5-HTP and L-dihydroxyphenylalanine,L-DOPA,5mg/100g body weight)were injected daily,8and 12h apart in two groups of one-day ld chick,while cotrols received two daily injections of normal saline.Weekly/biweekly observations(body weight,cloacal gland size,testicular volume and activity,ovarian follicular diameter and rate of egg production)were made until 9 weeks of age,when the experiment was terminated.Results indicate that 8 h relationship completely suppressed gonadal growth even under long photoperiod(LD16:8),while a 12 h relationship induced precocious sexual maturity and increased the rate of reproductin(spermatogenesis and egg production).It is concluded that circadian phase relationship of serotonergic and dopaminergic activity may not only determine the onset of reproduction in this pultry species,but may also alter the rate of reproduction possibly by affecting photoperiodic mechanism of reproductive regulation.
