Objective:Reference to the risk loop in hospital accreditation spot tracing method, enhancing the management of medical equipment.Methods: By six link as planning, training, implementation, monitoring, feedback, improvement in the spot tracing method to implement the management of medical equipment.Results: Evaluate the risk level of medical equipment by the risk value evaluation, thereby setting clinical equipment training period and mode, and apply the result of training assessment to feedback adjusting ,use monitoring and use effect improving.Conclusion: By preventing and controlling the risk of medical equipment, the original medical management was promoted to a new level, more in line with the requirements of medical service safety and standardized level in hospital accreditation.

Objective To discuss the expression of cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) in adenomyosis and its clinical significance. Methods The expression of COX-2 and VEGF was examined by immunohistochemistry SP method, in ectopic endometrium and eutopic endometrium, compared with normal endometrium. Results (1) COX-2 expression in ectopic, eutopic endometrium with adenomyosis was significantly higher than that in control group (P<0.05). No statistically significant difference was found between ectopic endometrium and eutopic endometrium group with adenomyosis (P0.05).(2) VEGF expressions in ectopic, eutopic endometrium with adenomyosis were both significantly higher than that of control group (P<0.05); no statistically significant difference was found between ectopic endometrium and eutopic endometrium group (P0.05).(3) COX-2 and VEGF had the positive relativity in the ectopic endometriumal expression of adenomyosis patient (P<0.05). Conclusion COX-2 and VEGF may play a key role in adenomyosis. Both may have close relation in angiogenesis and may provide new targets for therapy of adenomyosis.

Objective To study the hygroscopicity of glucosamine sulfate powder.Methods Hygroscopic studies were conducted on glucosamine sulfate powder at 5℃ and 30℃ used gravimetric method,determined the equilibrium moisture content(EMC) and drew the moisture sorption isotherms.The experimental values were regressed using the BET model,calculated the monolayer moisture content.Results At 30℃,when water activity exceeded 0.43,samples agglomerated,browned and lose adsorbed water,EMC declined;At 5℃,the isotherm had typical ob-S shape,the EMC increased with water activity raising.At 30℃ and 5℃,the monolayer moisture content were 4.8633,5.5740g/100g respectively.Conclusion At 5,30℃ the appropriate aw for storage appeared to be below 0.3056,0.2784,respectively.

Objective:To check the clinical effect of Multi-channel Brain Magnetic Stimulation Machine.Method:Sixteen volunteers are divided into two groups.Members of the first group which is the corresponding group listen to news material in the sober state and then answer the questionnaire.At last their EEG is collected.Members of the second group listen to the same material in the sober state and they are stimulated at the forehead and temporal area by Multi-channel Brain Magnetic Stimulation Machine at the same time.They also answer the questionnaire under the magnetic stimulation at forehead and their EEG is collected,too.Result:Answers of the second group are obviously better than the first group.The power spectrum of EEG at the forehead,temporal,parietal region and even the whole brain area in the first group is stronger than that of the second.Conclusion:Multi-channel Brain Magnetic Stimulation Machine excites brain in a way and then helps people complete the job better.

Objective To investigate the clinical significance of changes in vascular endothelial cells during the development of glucocorticoid-induced avascular necrosis of femoral head(GANFH),and the preventive and therapeutic effects of "Cugusu Keli",a mixture of traditional Chinese medicines,on GANFH in rabbit.Methods Forty-eight New Zealand white rabbits were randomly assigned to four groups,12 in each,as control group,model group,therapy group and prevention group.The contents of plasma von Willebrand's factor(vWF),6-keto-prostaglandin F1?(6-keto-PGF1?)and the activity of plasminogen activator inhibitor 1(PAI-1)were determined at the 2nd,4th,6th,8th and 12th week after treatment.Meanwhile,rabbits were sacrificed at the 4th,8th and 12th week,and both femoral heads of all rabbits were obtained for histopathological examination.Results Compared with control group,the level of vWF and activity of PAI-1 in model group were elevated since the 4th and the 2nd week,while the level of 6-keto-PGF1? increased since the 4th week(P0.05).Compared with the model group,the level of vWF and activity of PAI-1 in therapy group was lowered,while the level of 6-keto-PGF1? increased(P

ObjectiveTo study the way for establishing prediction model of acute pancreatitis with secondary multiple organs dysfunction syndrome (MODS) in the early stage.MethodsThe linical data were collected from 113 hospitalized patients with acute pancreatitis admitted from October 2008 to October 2011.Some biomarkers within 48 h after the onset of acute pancreatitis were statistically analyzed by univariate and multivariate binary logistic regression analysis in order to establish the prediction model evaluated by the ROC curve. ResultsThere were statistically significant differences in lactate dehydrogenase ( LDH ),serum creatinine ( CR),serum albumin ( P ＜ 0.05 ) identified by univariate regression analysis.These independent risk factors in the regression model were:ln (P/1 -P) =2.243 +0.002 × LDH + 0.014 × CR - 0.186 × ABL,likelihood ratio test ( x2 =66.46,P =0.000) ; in the ROC curve analysis:AUC 0.927 (95％ CI:0.875 -0.980),the best cut- off value of the model predicting probability was 0. 177 (sensitivity 82. 14％,specificity 85.88％,correctly classified 84.96％ ).ConclusionsEfficient prediction model could be set up by the logistic regression analyzing the early risk factors in multiple organ dysfunction syndrome following acute pancreatitis.
