Methods: A total of 71 patients with preeclampsia who were treated in Zigong Third People's Hospital between December 2014 and February 2017 were retrospectively analyzed and divided into the control group (n=38) who accepted conventional low molecular heparin therapy and the study group (n=33) who accepted low molecular heparin combined with Roy adaptation model therapy. The differences in hypercoagulable state, endothelial function and placental blood perfusion were compared between the two groups before intervention and after 8 weeks of intervention. Results: Before intervention, there was no statistically significant difference in the hypercoagulable state, endothelial function and placental blood perfusion between the two groups of patients. After 8 weeks of intervention, peripheral blood coagulation indexes TT and AT-Ⅲ levels of study group were higher than those of control group while D-D level was lower than that of control group;serum endothelial function index NO content was higher than that of control group while ET-1 content was lower than that of control group;ultrasonic placental blood perfusion parameters FI, VI and VFI levels were higher than those of control group. Conclusion: Low molecular heparin combined with Roy adaptation model intervention could further reduce the hypercoagulable state, decrease the vascular endothelial injury, and eventually increase the placental blood perfusion in patients with preeclampsia.展开更多

Materials and Methods: A pretest-posttest experimental model with a control group. Study population comprised postpartum women (N = 134;65 in the experimental group, 69 in the control group) who had caesarean full-term delivery in a Turkish maternity hospital between September 2009 and February 2011. Data were collected from the experimental group during seven home visits and from the control group at the end of the 6th week postpartum. Results: Percentage, chi-square, arithmetic mean, standard deviation, and the McNamer test were used to evaluate data establishing 36 nursing diagnoses: Physiological requirements (22), Self requirements (7), Role Function requirements (4), and Interdependence Mode requirements (3). It was determined that the care given during the postpartum period using Roy’s Adaptation Model resolved or prevented the majority of postpartum problems. The difference between most diagnoses was found to be statistically significant (p p < 0.001) during the last week of data collection. Conclusion: The care given in the postpartum period using Roy’s Adaptation Model resolved or prevented postpartum problems.展开更多

A two-dimensional Re-Normalisation Group （RNG） k-ε model was developed to simulate the flow in the reach. In order to take the circulation currents in the bends into account, the momentum equations were improved by adding an additional source term. Comparison of the numerical simulation with field measurements indicates that the improved two-dimensional depth-averaged RNG k-e model can improve the accuracy of the numerical simulation. A rapid adaptive algorithm was constructed, which can automatically adjust Manning＇s roughness coefficient in different parts of the study river reach. As a result, not only can the trial computation time be significantly shortened, but the accuracy of the numerical simulation can also be greatly improved. Comparison of the simulated and measured water surface slopes for four typical cases shows that the longitudinal and transverse slopes of the water surface increase with the average velocity upstream. In addition, comparison was made between the positions of the talweg and the main streamline, which coincide for most of the study river reach. However, deviations between the positions of the talweg and the main streamline were found at the junction of two bends, at the position where the river width suddenly decreases or increases.展开更多
