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 establish the medical equipment archives management system to adapt to the Finance Ministry new hospital financial system. Methods:According to the new financial system requirements, implement the new file management strategy, as adjusting the original classification, management object and process. Results: After the implementation of the new management strategy, medical equipment archives management and new financial system in our hospital realize synchronous in January 1, 2012, thethree Zhang cardsystem optimizing, and the results have been applied to the existing hospital medical equipment management software, greatly improving the efficiency of management, provides a strong basis for medical equipment economic benefit and social benefit evaluation. Conclusion:The medical equipment archives were giving full play to improve the quality of medical care.

Objective To study the levels of bone alkaline phosphate (BALP) in healthy children in the specific hospital.Methods Totally 990 healthy children from 0-16 years old were selected,all of whom received physical examination in the Xiasha branch of Zhejiang Provincial Hospital of TCM during August 2013 to April 2014.Serum was collected and tested for BALP levels with a Beckman Coulter Immunoassay System UniCel DxI 800.Z-test was used to verify age and gender grouping,after which the 2.5th and 97.5th percentile values of serum BALP levels were calculated.Results The levels of serum BALP(bilateral 95% range) in healthy children were as follows:trottie stage (0-1 years old):37-300μg/L;infancy to school stage (> 1-9 years old):40-196 μg/L;puberty stage (>9-16 year-old):25-284 μg/L (male),30-199 μg/L (female).The serum BALP levels of male children showed a weak correlation with height,while the correlation for female children was not significant.Conclusions The levels of BALP in healthy children of the specific hospital and area were established.Serum BALP levels in children varied with age and sex.
6.Establishment of regression model of acute pancreatitis complicated with secondary multiple organs dysfunction syndrome for prediction and evaluating its efficacy
Chinese Journal of Emergency Medicine 2012;21(8):815-818
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.

Objective To evaluate the effect of direct stenting on no-reflow in patients with ST-segment elevation (STEMI) acute myocardial infarction. Methods A total of 157 patients with STEMI received direct stenting (DS,n=85) or conventional post-dilation stenting (CS,n=72). The time of X-ray exposure, the amount of contrast media consumed, the TIMI grading after stenting and ST-segment changes of electrocardiogram were compared between two groups. Results The time of X-ray exposure and the amount of contrast media consumed were significantly less in DS group than those in CS group [(24.6?16.9) min vs (34.4?17.5) min, (115?37) mL vs (166?61) mL, P
