ABSTRACT
Objective To introduce the methods of performance excellence management model in clinical nursing teaching. Methods A total of 110 clinical nursing interns were selected before and after implementation of performance excellence model, traditional teaching method was used prior to the implementation of performance excellence model. The teaching quality evaluation, teachers teaching level feedback, examination of interns, teachers′ satisfaction degree with nursing work were investigated and compared before and after the implementation of performance excellence model. Results After the implementation of excellent performance management model, the assessment of interns with teaching quality scored from 3.75±0.51 (before the implementation) to 3.98±0.14, t=-6.738, P<0.01. Examination of interns by teachers scored from 92.44 ± 1.44 to 95.01 ± 2.20, t=-7.24, P<0.01. Teachers′satisfaction degree with nursing work scored from 3.91 ± 0.44 to 4.26 ± 0.46, t=-3.006, P<0.01. Conclusions The application of excellent performance management model in the hospital clinical nursing teaching can effectively improve the quality of teaching as well as satisfaction degree of nursing interns, teachers and departments.
ABSTRACT
A novel method was established for the qualitative and quantitative determination of fatty acids in Channel Catfish muscle by gas chromatography-electron ionization-mass spectrometry (GC-EI-MS) after supercritical carbon dioxide fluid extraction (SFE-CO_2). The extraction parameters for the methodology were optimized). The optimal conditions were extraction pressure of 25 MPa at 45 ℃ and extraction time of 100 min at the rate of carbon dioxide 30 L/h. The fatty acids in the muscle oil were derived by boron-trifluoride method). The saponification time was 10 min, and the esterication time was 20 min. The obtained fatty acid methylesters were separated by gas chromatography using a HP-Innowax capillary column, and were detected by electron) ionization) mass spectrometry. Full scan mode and SIM mode were used for the qualitative and quantitative analysis), respectively. In the SIM mode, saturated fatty acids were determined with m/z 74, mono-unsaturated) fatty acids were determined with m/z 55, double-unsaturated fatty acids were determined with m/z 67, and polyunsaturated fatty acids were determined with m/z 79. The detection limits of 14 fatty acids were 2.2-20.0 μg/L(S/N=3)), and the quantitative limits were 7.39-59.85 μg/L(S/N=10). The recoveries fell in the range from 90.0% to 111.2%(n=4), and the relative standard deviation was between) 2.0% and 5.9%. This effective, sensitive and reproducible method can be used for the determination of fatty acids in Channel Catfish muscle sample.
ABSTRACT
OBJECTIVE:To observe the clinical efficacy of insulin glargine versus intermediate-acting insulins(NPH)injected subcutancously at bedtime in initial diabetes mellitus cases.METHODS:64 initial type 2 diabetes mellitus cases were assigned to insulin glargine group(A)or NPH insulin group(B).Both groups were subcutancously injected with short-action insulin on the basis of alimentary control and a certain amount of activity.Comparison was made between the two in respect of fasting blood glucose(FBG),duration of glycemic control,glycemic excursion,hypoglycemic incidence and total daily insulin dose.RESULTS:FBG,duration of glycemic controlling,glycemic excursion and hypoglycemic incidenc were lower in glargine insulin group than in NPH group(P
ABSTRACT
In this study, 116 subjects with impaired glucose tolerance were followed up for 3 years. The results showed that the incidences from diabetes and coronary heart disease in acarbose treatment group were less than those in the control group.
