Objective To explore the double center teaching model in the application of emergency nursing teaching effect. Methods 120 higher vocational nursing students were randomly divided into experimental group(60) and control group(60). The experimental group used the double-center teaching mode, while the control group used traditional teaching mode. At the end of the course, students of both groups were given theoretical examination and skills examination, and the experimental group students' self-evaluation was surveyed by questionnaire . The obtained data were statistically analyzed using SPSS 12.0 software, with the test scores represented by (x±s), questionnaire, investigation with percentage statistics and comparison between groups with t test. The difference was statistically significant ( P=0 . 034、0 . 016、0 . 000 ) . Results The experimental group's theory achievement , case analysis result and practical result were all higher than those of the control group, and the difference was statistically significant (P=0.034, 0.016, 0.000). 93.33% of nursing students thought that double main teaching effect was better; 88.33% of nursing students thought it could develop their ability to learn independently;86.67%of nursing students thought it could enhance the team cooperation spirit;85.00%of nursing students thought that it could improve the efficiency of first aid knowledge learning and first aid skills. Compared with t test between groups, the difference was statistically significant, (P<0.05 ). Conclusion The double-center teaching mode is an effective model to improve the effect of emergency nursing teaching, and it will provide the basis for other disciplines teaching reform.

Objective to reveal the research situation about food safety in China by analysing the articles published from 2000 to 2008. Methods bibliometrics were used to analyze the articles. The cooperation and the distribution of foundations were searched out from CBMdisc ( China scientific journal Database) with "food safety" as keywords. Results 1829 documents and 4,063 authors were identified. The rate of cooperation was 68.05% and the authors came from 32 provinces, autonomous regions and special administrative regions of China. 194 papers were supported by various kinds of fund. Conclusion Research on food safty is developing fast to meet the soring needs in this respect of the society.

In this study, the effect of Rhizoma Alismatis on experimentel fat rat caused by monosodium glutamate which was injected hypodermically at large doses into fant rats has been observed.The conclusion of experiment shows that the rat weight increased, the Lee exponent value was obviously larger than that of control group, the fat in body was accumulated in abundance and the content of serum triglyceride markedly rose after 10 weeks when monosodium glutamate was injected. The Rhizoma Alismatis can reduce Lee exponent value of fat mice, fat exponent and serum triglyceride content in periphery of uterus and testis, which suggested that it possessed a certain action against fat.

The maximum specific binding(Bmax)and the dissociation constants(K D) of 8H -dihydroalprenolol in rat myocardial membrane are 104.1 +4. 7 fmol/mg protein and 10.1+2.7nM, respectively, and the Hill coeffici-ent(nn) is equal to 1.007+0.002. The half inhibition concentration concentration ( IC50) of bunitrolol and propranolol on 3H - dihydroal- prcnolol binding to myocardial B-adrenergic receptors are 3.30+ 0. 74 x 10- 8M ,and 3. 87+0.66 x 10-7M , the apparant dissociation constants (Kl) are 2.2+0.48x10-8M and 2.58+0.44x10-7M, respectively. The affinity of bunitrolol to myocardial B-adrener-gic receptors is 11.7 times as potent as propra'nolol.

Study of the strategic objectives chosen by hospitals from the perspective of stakeholders is now under the spotlight of researchers at large. To identify whether there exist differences in strategic objectives among various groups in the hospital and probe into the causes, the author called into play the competing values framework as the analysis tool. An evidenced-based study on public hospitals in Hangzhou identified marked differences on choices of strategic objectives among various internal stakeholders in the hospital For example, hospital administrators tend to focus on internal control, while medical doctors tend to focus on interactions between the hospital and the external environment. On this basis, further studies are proposed.

Objective To investigate the effect of glutamine intensified TPN on nutritional state and immunofunction in the postoperative patients with gastrointestinal tract tumour.Methods 20 patients were divided into two groups including standard TPN group (control group,10 cases) and Glutamine intensified TPN group(study group,10 cases). Period of treatment was 8 days.Immunofunction(IgG,IgM,IgA,C 3,C 4), serum albumin , nitrogen balance were tested.Results (1)The patients serum albumin in the study group was increased significantly as compared with control group (P

To study the characteristic of the metacarpal fracture and the forensic investigation of severity of the injury.52 cases with metacarpal fracture were reviewed.The incidence and the location as well as the patterns of fracture were analyzed.The severity of the fracture were different with different mechanism.

Objective To evaluate the profile of transient ischemic attacks in younger patients compared with older patients effectively.Methods We study 75 younger patients(≤45 years)compared with 90 older patients(≥65 years).History of presenting transient ischemic attacks,etiology,clinical feature and lab investigation were compared on the basis of the above age groups.Results Overweight、hypercholesterolemia、insomnia and vascular disease family history being more common in the younger group and Hypertension,ischemic heart disease,long-term history of smoking being more common in the elder group.Diabetes and high serum uric acid occurred high frequently in both groups.Conclusion A significant correlation existed between etiologies contribution and adverse life custom,the early management should be take up to prevent TIA occurrence.

Objective: To investigate the short-term efficacy and safety of recombinant human endostatin YH-16 combined with navelbine and cisplatin in the first line treatment of advanced non-small cell lung cancer (NSCLC) and its effect on the survival. Methods: Eighty patients with advanced NSCLC were recruited from May, 2007 and May, 2010, and they were randomly divided into study group (n=40, treated with YH-16 combined with navelbine and cisplatin) and conrol group (n=40, treated with navelbine plus cisplatin). The short-term efficacy and adverse effects were evaluated every six weeks (one chemotherapy cycle was given every 3 weeks). The survival was calculated. Results: Thirty-nine patients in the study group and 36 patients in the control group were evaluable. The stable disease rate in the study group was higher than that in the control group (53.8% vs 27.8%, χ2=5.25, P=0.022), and the clinical benefit rate was also higher (76.9% vs 55.6%, χ2=3.85, P=0.050). The progressive disease rate in the study group was lower than that in the control group (23.1% vs 44.4%, χ2=3.85, P=0.050). There were no significantly differences in time to progression and overall survival between the two groups (P>0.05). Most adverse effects were hematologic toxicities and digestive reactions, and the incidence rate was not significantly different between the two groups. The incidence rate of abnormal electrocardiogram in asymptomatic person was higher in the study group than that in the control group (χ2=16.27, P=0.001). Conclusion: YH-16 combined with navelbine and cisplatin as the first line treatment for advanced NSCLC can improve the stable disease rate, and the clinical benefit rate, decrease the progressive disease rate, and increase the rate, of cardiac electrophysiological abnormality, but the overall safety is acceptable.
