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.

Objective To observe the clinical short-and long-term curative effect of the surgical treatment of female stress urinary incontinence (SUI) with tension-free vaginal tape-obturator (TVT-O) treatment,and discuss the safety of the operation and postoperative quality of life.Methods The data were collected from 130 patients with SUI who were underwent TVT-O treatment.The patients'perioperative period,follow-up of postoperative complications,and comparison of the quality of life before and after surgery were analyzed retrospectively.Results A total of 130 patients was successfully completed their surgeries with a mean operative time (47.01 ± 18.82)min,average blood loss (64.38 ±99.62)ml,mean catheterization (2.67 ±0.90)d,and the average length of stay (4.73 ±2.14)d.A total of 101 cases was completed the postoperative follow-up with (a) preoperative quality of life in patients with ⅡQ-7 score 6 to 21 points and an average of (15.74 ± 3.87) min,(b) symptoms of lower urinary tract UDI-6 score of 3 to 22 minutes and the average (10.51 ± 3.70) min,(c) postoperative quality of life improved significantly ⅡQ-7 score from 0 to 21 points and an average of (1.59 ±4.37)points,and (e) UDI-6 score 0 to 14 points and an average of (1.63 ± 2.66)points.A total of 73 patients (72.3％) had the postoperative urinary incontinence,which subjective symptom were completely cured,significant improvement was 11 cases (10.9％),ineffectiveness was 6 cases (5.9％),pad using was 13 patients (12.9％),vaginal mesh exposure and erosion was 2 patients(2.0％),the sexual life postoperatively was affected in 8 patients (7.9％).Conclusions TVT-O treatment of SUI is not only easy to operate but also has clinically high security,few complications,low recurrence rate,and significantly improved patients' living quantities.However,patch compli cations can not be ignored and need further discussion.

Horizontal gene transfer (HGT), also Lateral gene transfer (LGT), is any process in which an organism transfers genetic material to another species that is not its offspring. With the increase of available genomic data, it has become more convenient to study the way to detect the genes, which are products of horizontal transfers among a given genome. There are few data about known horizontal gene transfers in three bacterium genomes under consideration, so the experiments, which simulated gene transfer by artificially inserting phage genes, were carried out. Combining the feature analysis methods of gene sequences with support vector machine (SVM), a novel method was developed for identifying horizontal gene transfers (HGT) in 3 fully sequenced bacterium genomes (Escherichia coli K12, Borrelia burgdorferi, Bacillus cereus ZK). According to our previous work, codon use frequency (FCU) was selected as the sequence feature, in respect that it is inherently the fusion of both codon usage bias and amino acid composition signals. In addition, another computational method was proposed considering strand asymmetry and predicting horizontal gene transfers of leading strand and lagging strand of genomes under consideration, respectively. To avoid the occasionality of simulating gene transfer through artificially inserting phage genes, 100 times of the transfer-and-recover experiment were repeated and arithmetic average of measurement for each genome being considered were reported to evaluate algorithm's performance. Ten-fold cross-validation was used for both parameter and accuracy estimation. The best results were obtained for C-Support Vector Classification (C-SVC) type by using the radial basis function kernel with ?=100, while for one-class SVM type the best performance was obtained using the polynomial kernel of three degree. The performance of the approach was compared with that of Tsirigos' method ,which is one of the best predictive approachs to date in detecting of horizontal transfer genes. Firstly, for the original method that did not consider the strand asymmetry, the C-SVC type has a high relative improvement(RI) of 31.47% on hit ratio for Escherichia coli K12, while the one-class SVM type has RI of 11.61% for Borrelia burgdorferi. Moreover, as theoretically expected, the method considering the strand asymmetry resulted in higher RI than the original method. In order to examine the approach's performance in detecting factual gene transfer events, the approach was applied in genome of Enterococcus faecalis V583. It is not only succeed in recovering all the seven factual horizontally transferred genes, also found that the whole segment from 7 kb upstream of gene EF2293 to 38 kb downstream of gene EF2299 was probably transferred into E. faecalis V583 genome simultaneously with the above seven genes.
