OBJECTIVE:To carry out drug risk management so as to ensurethe safety of clinical drug use in the hospital. METHODS:The mode of drug risk management of our hospital was established,in the form of drug risk identification,risk evalu-ation,risk control and risk review,and the measures for risk management were developed and taken. The effect of drug risk man-agement was evaluated after 3 years (2012-2014) of colletion and analysis of the questionnaires given to clinical medical workers and patients and the results of evaluation by the group of pharmacy management and quality control for drug use in the hospital. RE-SULTS:Following the establishment and improvement of drug management information system,the strengthening of the manage-ment of special drugs,strict implementation of the Management System for the Return and Recall of Drugs,the establishment of specialized drug safety monitoring body,the development and implementation of the measures such as self-inspection in the hospi-tal,the problems about drug safety in our hospital had been decreasing from 2012 to 2014(88,42 and 19 cases respectively);and 96.59%,97.62% and 100% of drug safety problems were solved by the pharmacy staff to the satisfaction of the group of pharma-cy management and quality control for drug use in the hospital respectively in the three years. CONCLUSIONS:The mode of drug risk management established in our hospital has promoted the safety of drug use.

Hyperpolarization-activated and cyclic nucleotide-gated (HCN) channels, distributing in a variety of tissues, especially in excitable cells such as heart cells and many kinds of neurons, have an important role in the modulation of heart rate and neuronal excitability. Different from typical voltage-gated sodium channels and potassium channels, HCN channels were evoked inward currents when the cell was hyperpolarized. More and more recent studies have disclosed that HCN channels play important roles in the nervous system, which were linked with its special electrophysiological features as well as its regulatory effect on the cellular membrane excitability. HCN channels could be modulated by many factors including both extracellular molecules and intracellular signaling cascades, which made its functions complicated in the different condition. Based on its role, HCN channels are presumed to be a promising target for chronic pain and brain disorders. In this paper, we will focus on the advancement of roles of HCN channels in the neural system as well as its complex modulator factors.

Objective To study pre-thrombosis state in patients with cor pulmonale and analyze the value of treatment with low molecular heparin (LMH). Method 46 patients with cor pulmonale were divided into LMH group and routine one. Von Willebrand factor (vWF), prethrombin F 1+2 fragment (F 1+2 ), Fibrinogen (Fg), granule membrane protein (GMP-140) and D-dimer fragment (DD) were detected separately.Result The concentrations of WF,F 1+2 ,Fg,GMP-140 and DD in the patients with cor pulmonale were significantly higher than control. In LMH group, these variables and PaCO 2 decreased and PaO 2 increased markedly after treatment. In routine group, these blood-gas index slightly improved, but no decrease were observed in coagulation variables. Conclusion Early detection and diagnosis of pre-thrombosis state in patients with cor polmanate and timely treatment with LMH can be beneficial to these patients during acute state.

On the basis of the research on the work of subject librarian,this article describes the concrete conceive about constructing the key discipline information service platform in universities,analyzing the practical significance,the practical value and the problems to be dissolved in discipline construction.

BACKGROUND: Patients with Alzheimer disease (AD) usually have visuospatial dysfunction at an early stage and most patients with AD were evolved from mild cognitive impairment (MCI).OBJECTIVE: To detect whether a patient with MCI has a visuospatial dysfunction similar to AD. To compare the cerebral activation with ferromagnetic resonance between the healthy people and the patients with mild cognitive disorder.DESIGN: A case controlled observationSETTING: The Department of Neurology of the First Hospital of Peking University.PARTICIPANTS: Nine inpatients with mild cognitive disorder hospitalized at the Department of Neurology of the First Hospital of Peking University from April 2000 to March 2003 were involved and other 9 healthy people matching in age, gender and the educational level were also involved.METHODS: The subjects had the task of discriminating the different finger positions on the clockface. They could see the mission clearly showed on the cloth through refractor, and they were supposed to give the corresponding reaction to different cognitive tasks with left and right hands pressing the keys according to visual sign generated by the computer.Block design was adopted in the cognitive task. Stimulus block and baseline block appeared in turn. Baseline block displayed "+" mapped in the center of the image and was kept for 21s. Stimulus block displayed 10 pictures successively. The finger position of the two clockfaces among three clockfaces was the same in one picture. The absolute value of the rotated angles of the different clockfaces in each image on the same stimulus block was the same. The angles formed by six stimulus block fingers arranged randomly were 300, 450, 1800. The two clockfaces had the same finger positions, and the subjects were requested to discriminate the finger position of these two clockfaces. It was carried out on a 1.5 T GEMRTWIN magnetic resonance scanning apparatus. Then t test was performed to work out the right reaction time and proper rate with Excel software between the patients with mild Alzheimer's disease and the healthy persons. Pretreatment and statistical analyses were performed with analysis of functional neuroimages software used internationally.MAIN OUTCOME MEASURES: Comparison of the reaction time and proper rate between the two groups.parison of the reaction time between the two groups: The reaction time for distinguishing the change of 300, 450, 1800 was longer than that in the control group, and there was significant difference in distinguishing the change of 300, 450, 1800 for the patients [(1 776.7±570.2), (1 646.3±432.7)ms;of the proper rate between the two groups: The proper rate for distinguishing the change of 300, 450, 1800 was significantly lower than that in the control group (62.8±21.4)%, (82.8±15.8)% ;(76.7±17.0)%, (95.0±8.7)%; (69.4vation: the activation density at the bilateral parietal lobe, bilateral temporooccipital borderline and bilateral lateral striate cortex in patients was weaker than that in the control group (P ＜ 0.05).CONCLUSION: Neural network activation related with visual space in patients with MCI was weaker than that in the healthy people indicating that visuospatial impairment exists in the patients with mild cognitive impairment.

Objective To evaluate the effect of recombinant human erythropoietin(rhEPO)on pressure induced retinal ischemic injury in rats.Methods The fluorogold(FG)tracing technique was used to observe the survival rate of the retinal ganglion cells(RGCs).Retinal ischemia was induced by increasing the intraocular pressure to 102 mmHg for 60 min in 20 Long Evans rats,then 5 ml rhEPO was injected into the right vitreous chamber immediately and normal saline into the left vitreous chamber as vehicle controls.Another 5 rats without any treatment served as normal controls.All animals were sacrificed at 1,4,7 or 14 d after reperfusion and RGCs were counted to assess the effect of rhEPO.Results The RGCs in eyes treated with intravitreal rhEPO were significantly higher than those in vehicle controls(P
