Based on computer and network technologies,the information system has grown into an important part for normal operation of hospitals,pushing up the importance of its risk analysis and defense.This article briefly described general methods and processes of risk analysis for information system,brought forward methods of risk classification and level-defense to identify and manage risks effectively,highlighted the importance of risk analysis,after-defense evaluating and tracking.This method is called into play to identify risks exposure of the information system of Beijing Red Cross Blood Center,contributing to a risk response table,developing a sustained improvement process for risk identification,control,appraisal and tracking,with defense carried out in specific system upgrading projects.

Callus of Gentiana crassicaulis was initiated from hypocotyl and cotyledon on MS medium supplemented with 2mg/L 2.4-D and 0.5 mg/L BA.Induction frequencies of callus were 100%.Somatic embryos were formed on MS medium containing 2mg/L BA,3mg/L ZT, 1mg/L NAA,3mg/L GA,three time MS organics and vitamins,6% sucrose and 500 mg/L LH and three time FeSO4 (Na2EDTA) .40% Callus produced somatic embryos.It developed into complete plants on hormon-free MS medium.

Hepatobiliary surgical intervention technique is a treatment and diagnostic technology developed relatively rapid in recent years,it is responsible for diagnosis and treatment of important organs such as hepatobiliary pancreatic disease,and with characteristics of minimally invasive,video,safe,simple,quick recovery,less complications,patients easily accepted and so is widely used in clinical.With the popularization and rapid development of this technology,the demand for physician intervention greatly increased,setting off a wave of interventional study.Our hospital has carried out hepatic artery embolization imaging technology and chemotherapy,interventional radiology treatment of biliary tract,portal vein involvement of hepatobiliary surgical intervention since 1980s,the cumulative number of cases of hepatobiliary surgical intervention reached million and attracted many national hospitals to send officers to learn the technology.In the teaching process,we accumulated some valuable experience.

Effective leadership is crucial for health organizations' performance and numerous western universities thus offer leadership courses or modules to their students.However,such education practice has not started in China.In order to optimize knowledge and skills of health service management practitioners,to content with requirements of health service organizations,to cope with dynamic organization environment,to implement health reform successfully and to realized sustainable development of health organizations,it is necessary to provide leadership course for students of health service management at Chinese universities.

Glycoprotein N is encoded by glycoprotein N (gN) gene of herpesviruses. The amino acid composition and expression level of this protein vary among difference species of herpesviruses. According to present studies, gN protein is expressed in cytoplasm of host cells, mainly in endoplasmic reticulum. The gN forms a complex with glycoprotein M in host cells. The complex is involved in the processes of viral replication and inter-cellular infection. Moreover, this protein plays a role in immune evasion from host immune system. The study will provide a theoretical basis for further study of herpesvirus gN gene and its encoded protein.

Objective To investigate the effects of esmolol on ATPase activity in myocardial mitochondria after resuscitation in rats.Methods Sixty-six male Wistar rats were randomly allocated to three groups:sham group,AD group,AD+Es group.A cardiac arrest model was reproduced by asphyxiation in rats,and then CPR was performed in these animals after 10min asphyxia.The ATPase activity of myocardial mitochondria was determined at 30th,120th and 180th minute after resuscitation.ECG,MAP,HR and temperature were measured continuously.Results Heart rates were significantly higher after adrenaline when compared with sham group.Myocardial mitochondria ATPase activity was decreased significantly in both AD and AD+Es group compared with that of sham group(P

Objects: To measure practicing medical students' basal energy expenditure(BEE). Methods: 200 practising medical students were chosen to measure BEE by standard method of CCM metabolism cart,and the BEE results were compared with forecast values from the calculation formula of healthy adult. Results: Actual BEE of male students was(4 920.4?1 343.1)kJ/d,female(3 393.2?824.2)kJ/d.The results were significantly lower than corresponding forecast values.Conclusion: The BEE of practising medical students is lower than forecast values from the calculation formula of healthy adult,showing that students' constitution was poorer.The possible reasons may be less exercise and diet.

OBJECTIVE To investigate the strategy of information system in antibiotics usage management. METHODS By inquisition,statistic and analytic methods the antibiotics usage information of the hospitalized patients was recorded with the information system,to realize the realtime monitoring and process management. RESULTS The usage rate of antibiotics decreased from 88.79% to 80.19% and the prophylactic usage rate of the third cephalosporin decreased from 72.34% to 11.25%.The rational usage rate increased from 57.89% to 80.18%. CONCLUSIONS The management method of antibiotics usage with information system achieves obvious effect.
