AIM:To study the effects of FK506 binding protein 12.6(FKBP12.6) overexpression on the performance of sarcoplasmic reticulum(SR) in ventricular myocytes of rats with heart failure.METHODS:The adenovirus(Ad)-mediated gene transfer was used to overexpress FKBP12.6 in ventricular myocytes of rats with heart failure.Western blotting and reverse transcriptase-polymerase chain reaction(RT-PCR) analysis were used to reveale specific overexpression of FKBP12.6.X-rhod-1-AM was used as the Ca2+ indicator,and cells were viewed under a confocal microscope.RESULTS:Adenovirus mediated overexpression of FKBP12.6 resulted in a 5-fold increase in relative FKBP12.6 mRNA levels and a 4-fold increase in relative FKBP12.6 protein levels at 48 h after transfection compared with control.The amplitude of the fluorescence [Ca2+]i transient was significantly increased in Ad-FKBP12.6-GFP cardiomyocytes compared with Ad-GFP myocytes(peak F/F0,3.16?0.42 vs 1.43?0.38,P

Objective: To analyze the prescription dosage for discharged patients in our hospital and investigate the potential risks.Methods: A retrospective research method was adopted to statistically analyze 55 872 discharge instructions from July to September in 2015,and more attention was paid to the prescriptions with dosage over 4 weeks,expecially the ones with 26-week dosage, and the related influencing factors were studied as well.

Objective To explore the establishment of methods to evaluate the quality of two different separate gel tubes .Meth-ods An evaluation comparing two separate gel tubes with silicate glass tubes ,which are the standard tubes ,was performed using data from 50 subjects .The serum samples were assayed for routine chemistry or immunology after centrifugation using the quantita-tive or qualitative detection methods such as ECL ,enzyme-linked immunosorbent assay (ELISA) ,reflection luminescence or immu-nofluorescence .The data were collect for further statistical analysis .Results For quantitative results of the items ,the two separate gel tubes ,compared with the standard glass tube ,there was no significant difference between the test results (P>0 .05);for quali-tative projects ,two separate plastic tube ,compared with the standard glass tube ,really the positive rate and the true negative rate was no significant difference (P>0 .05 ,K>0 .75) .Conclusion By using different detection methods and test items ,it is demon-strated that using two separate gel tube for items assay does not affect the accuracy and consistency of the test results .As a result , the method for external supplies quality assessment is established in the laboratory for ISO15189 quality control .

Objective A scientific evaluation of hospital culture with the Dimension organizational culture model, in view of features of China's general public hospitals.Methods Based on Denison model, according to the characteristics of the public general hospitals in China, the authors developed a tool for organizational culture assessment (TOCA) by using the survey data from 87 hospitals in three provinces from the East, Central, and West areas in China.Results This tool, an evaluation scale, comprises the four cultural characteristics of direction, consistency, participation, and adaptability, as well as 13 cultural dimensions of social responsibility and competitive consciousness. The tool is tested as having good internal reliability and validity.Conclusion The TOCA provides hospital administrators with a tool for hospital culture evaluation, diagnosis and improvement.

Objective To establish a simple and sensitive method for the determination of serum copper by spectrophotometry.Methods Nitro-PAPS was used as a coloring agent for serum copper in the presence of surfactants Tween-80 and Triton X-100 and the formed complex was measured by spectrophotometry.Results The maximum absorption wavelength of the complex was 570 nm and the molar absorption coefficient was 7.95?10~4 L/(mol?cm).The lineafity of the method was up to 63.0 ?mol/L and the recoveries ranged from 98.6% to 103.1%.The within-run and between-run CVs were 2.1%-3.3% and 2.7%-3.8%.The method(Y)was compared with an AAS method(X)and a correlation of Y=1.01X -0.27(r=0.998 2)was obtained.A reference interval(x~-?2s)determined with this method on 68 individuals was 9.7-24.1 ?moL/L.Conclusions A simple and sensitive method for serum copper has been established.It may used for the analysis of serum copper in clinical laboratories.

Objective To evaluate the safety of coronary intervention using iodixanol in patients with diabetic renal insufficiency.Methods Clinical data of 97 patients with diabetic renal insufficiency undergoing coronary intervention during June 2004 to June 2006 were retrospectively analyzed,50 of them with iodixanol,an iso-osmolar contrast medium (iodixanol group),and 47 with iopromide,a hypotanic contrast medium (iopromide group).Judkin's coronary angiography showed 167 diseased vessels in the patients,65 in anterior descending branches,44 in circumflex branches,and 58 in right coronary arteries. Levels of serum creatinine and blood urea nitrogen were determined before percutaneous coronary intervention (PCI),on the day of the procedure,the 3rd and 7th days after PCI,respectively,as well as radiocontrast media-induced nephropathy (CIN) was observed.Results Totally,192 drug-eluting stents were successfully implanted in 167 diseased vessels,and all patients' angina pectoris symptom disappeared soon after the procedure,with a full success.No acute or subacute stent thrombosis and major adverse cardiac events (MACE) occurred.Two patients (4%) in iodixanol group and 10 (21%) in iopromide group got CIN,with a statistical significance (P

Objective To study predicting results of the back propagation (BP)neural network model for hematoma enlargement (HE)in patients with intracerebral hemorrhage. Methods The clinical data of 128 patients with cerebral hemorrhage admitted to the 309th hospital of People′s Liberation Army from January 2011 to December 2014 were analyzed retrospectively. The Matlab 7. 14 software was used to achieve BP neural network model for predicting hematoma enlargement within 24 hours in patients with intracerebral hemorrhage (HE ≥6. 0 ml and HE ≥12. 5 ml). The mean square error (MSE)of the model and the accuracy of the overall prediction were calculated. The receiver operation characteristic (ROC) curve was drawn for predicting HE. Results When the BP neural network predicted HE ≥6. 0 ml and HE ≥12. 5 ml,the mean square deviations of the training set,validation set,and test set were 0. 061, 0. 143,0. 052 and 0. 023,0. 057,and 0. 065,respectively. The best fitting performance verification of hematoma enlargement was as follows:≥ 6. 0 ml for network training 11 times and the error value 0. 224;≥12. 5 ml for network training 20 times,and the error value 0. 057. The overall accuracies of predicting HE ≥6. 0 ml and HE ≥12. 5 ml were 92. 2% (118/ 128)and 96. 9% (124/ 128)respectively. Conclusion The BP neural network model have no special limitation for data. It can accurately fit the hematoma expansion model of cerebral hemorrhage.
