ABSTRACT
Objective To calculate Z-score for mitral and tricuspid color blood flow widths in normal fetuses and fetuses with dilated coronary sinuses ( CS ) using fetal echocardiography ,and explore the application value of Z-score of the color flow widths of atrioventricular valves in normal fetuses and fetuses with dilated CS . Methods Two hundred and thirty-eight normal fetuses (control group) with a gestational age of 16 to 38 weeks were studied by color Doppler echocardiography . Gestational age ( GA ) ,biparietal diameter (BPD) ,femoral length (FL) ,aortic inner diameter (AOd) ,pulmonary artery diameter (PAd) ,and heart area ( HA) were measured as independent variables ,and mitral and tricuspid valve color flow widths were measured as the dependent variables . Z-score models were established by regression analysis . Thirty fetuses with dilated CS (dilated CS group) from 22 to 33 weeks'gestation were involved . The Z-score of the CS fetus was calculated based on the established Z-score models and were compared with those of the normal fetuses . Results The independent sample t-test showed that there were no significant differences in the Z-scores of the blood flow width of the fetal mitral and tricuspid valves between dilated CS group and control group ( P >0 .05) . Conclusions The simple dilated CS does not affect the mitral valve diastolic blood flow ,so there is no significant effect on the filling of left ventricular blood flow .
ABSTRACT
Objective To provide referential information for intelligent construction in hospital pharmacy. Methods Combined with the practical application, this paper introduces the practice and experience of the intelligent construction of pharmacy in our hospital. Results The construction of intelligent hospital pharmacy improves the drug management level, improves work efficiency and increases the accuracy of the drug dispensing, increases medication guide time, improves patient compliance and satisfaction and reduces the work intensity of pharmacists. Conclusion The intelligent construction of hospital pharmacy has promoted the development of pharmacy and laid a good foundation for the comprehensive and in-depth development of pharmaceutical care.
ABSTRACT
Objective To explore the feasibility and effect of the multivariate integration teaching in clinical nursing teaching, improve the shortcomings of the traditional single teaching, and enhance the quality of clinical teaching and nursing students' satisfaction. Methods 117 clinical nursing students of the Department of Rheumatoid Immune Kidney of the Nanjing Hospital Affiliated to Nanjing Medical Uni-versity were chosen as the subjects and were divided into two groups, and 57 nursing students who practiced in the Department of Rheumatoid Immune Kidney from 2013 to 2014 were recruited to the experimental group to receive multivariate integration teaching method, with another 60 students who practiced in the Department of Rheumatoid Immune Kidney from 2012 to 2013 as control group to receive the traditional single model teaching method. Two groups of nursing students were given the unified theory test and clinical skills exam-ination as well as the evaluation of comprehensive quality and satisfaction survey. SPSS 20.0 software was used to give the general statistical description of the theoretical results, operating results, comprehensive quality, satisfaction and other measurement data. Examination results were expressed by x±s. t test, rank sum test was used for statistical analysis and the test level was α=0.05. Results Theoretical result of the experimental group was (96.283±2.330), operating result was (93.883±3.173), the compre-hensive quality evaluation result was (46.133±2.111), and satisfaction degree was (45.033 ± 5.966). Theo-retical result of the control group was (87.850 ± 4.953), operating result was (84.333±5.011), the com-prehensive quality evaluation result was (35.650 ±3.804), and satisfaction degree was (33.683 ±7.101). Conclusion Multi-variate integration teaching method is conducive to the cultivation of nursing students' clinical thinking and comprehensive quality, and can improve their ability to communicate with patients and enhance their self-confidence. Therefore it is an effective teaching method, worthy of popularization and application in all departments.
ABSTRACT
AIM: To optimize the extraction of Weining-Dispersible Tablet(Radix et Rhizoma notoginseng,Radix et Rhizoma ginseng) with the help of central composite design-response surface methodology. METHODS: The main influencing factors of extraction effect included the quantity of ethanol,the concentration of ethanol and extraction time and the extraction conditions were evaluated by the extract yield and the contents of total notoginseng saponins.The optimal extraction of Weining-Dispersible Tablet was selected by central composite design-response surface methodology. RESULTS: The optimal conditions consisted of extraction two times,2 h each time with ten fold of 70% ethanol. CONCLUSION: It is simple,convenient and high predictive to optimize the extraction craft of Weining-Dispersible Tablet by central composite design-response surface methodology.
