Objective To improve the digestion method of sewage samples for determing mercury with cold atomic absorption spectrometry.Methods 1+1 aqua fortis was used in microwave digestion of sewage samples instead of KMnO4-K2S2O8,then mercury was determined by cold atomic absorption spectrometry.Results The linear range was 0-10.0 ?g/L,the detection limit was 0.25 ?g/L,the relative standard deviation was less than 2.7% and the recovery rate was 95.0%-102.0%.It proved that the results by 1∶1 aqua fortis by microwave had high.Conclusion Compared with the KMnO4-K2S2O8 digestion method,microwave digestion method is simple,sensitive and suitable for determination of heavy metals in the environmental samples.

Objective To explore an evaluation method of quality of care using the 2012 medical record front page.Methods The admission pathway and discharge method information of inpatients discharge recorded in the medical record front pages of the hospital were chosen and evaluated with contingency tables.Results The outcomes indicated that the differences between discharge methods of those admitted through different pathways are significant statistically (x2 =856.55,P ＜ 0.05).The correlation analysis showed that the coefficient of Spearman correlation between the inpatients admitted through different pathways and their discharge methods was -0.11 (P＜0.05).Calculated as such,the score of quality of care was 4.95 for the hospital as a whole.Conclusion The establishment of this evaluation system showed that the indicators set for quality of care using the 2012 medical record front page are scientific,and the results are more objective.

Objective To detect the serum level of 3-carboxy-4-methyl-5-propyl-2-furanpropanoic acid (CMPF),a significant metabolite offish oil,in subjects with normal glucose tolerance (NGT) in local communities,and to investigate the association of CMPF with fatty acid metabolism.Methods A total of 272 NGT participants from screening for diabetes in Shanghai in 2013 were enrolled.Anthropometric measurements,biochemical evaluation,and questionnaire interview were performed for all the participants.The participants were divided into normal weight group [body mass index (BMI) ≤23.9 kg/m2,n =143] and overweight/obesity group (BMI ≥ 24 kg/m2,n =129).The serum CMPF concentrations were determined using an enzyme-linked immunosorbent assay.Results Serum CMPF level in overweight/obesity group was lower than that in normal weight group [96.50 (46.11,169.56) μmol/L vs 153.20 (83.16,282.97) μmol/L,P＜0.05].The serum CMPF level was negatively correlated with BMI (r =-0.256,P＜0.01),triglycerides (r =-0.175,P =0.004),and free fatty acid (r =-0.126,P =0.041) according to bivariate correlation analyses.A multivariate stepwise linear regression analysis showed that the serum CMPF level was independently associated with BMI,triglycerides,free fatty acid,and HbA1C.A logistic regression analysis showed that the CMPF was a protective factor against obesity (OR =0.324,95％ CI 0.158,0.664).Conclusion Serum CMPF level is reduced in overweight/obese subjects.CMPF is beneficial to lipid metabolism.

Objective To evaluate the application effect of the clinical nursing pathway for stroke′s patients by using the Meta-analysis.Methods The databases of Wanfang Data,CMA,CHDL and CBM were searched.This control study compared clinical nursing pathway and traditional nursing including from January 1998 to March 2014.Data collection and literature evaluation were performed by two reviewers independently. RevMan 5.2 was used for the Meta-analysis.Results Fifteen literatures included in Meta-analysis showed the statistical difference between clinical nursing pathway and traditional nursing on stroke′s patients in the average length of stay, average hospitalization expenses, patient satisfaction and Barthel index (P<0.05).Most trials included in the review had low quality.Conclusions The clinical nursing pathway has a better implementation effect compared with routine nursing, but there is a higher risk of bias in the literatures, and the results need a large number of clinical nursing practice and higher quality literatures to support.In practice, randomized control trials should be designed according to scientific methods and strict implementation.

Objective To explore the application of seasonal index in the ostomy nursing care outpatient′s quantity, grasp the regularity and forecast them. Methods The ostomy nursing care quantity in the outpatient of our hospital from January 2010 to May 2014 were counted, and the sequence was Seasonal decomposed, fitted and predicted. Results The correlation coefficient of the ostomy nursing care quantity in the outpatient and time series was 0. 914 ( P < 0. 01 ). It had a long-term growth trend and the seasonal characteristics. The middle seasonal index was higher than both ends of the seasonal index. The model was well fitted and the predicted outpatients in 2014 continued to increase steadily. Conclusions The seasonal index is suitable for hunting variation of ostomy nursing care outpatient′s quantity and grasping the future trend. The seasonal index applies for the ostomy care outpatients provides a reference for hospital administrators grasping the variation, and a new way to forecast the future ostomy care development.
