0.8.There was concurrent validity between CSS and NIHSS(r=0.86).The prognosis prediction accuracy of CSS was 92.4%,slightly lower than that of NIHSS(94.1%).Logistic regression showed that CSS's "gaze function" and "facial paralysis" were not included in the prediction equation.The facial paralysis had a SES of 0.38,all others had a SES higher than 0.5.Most fields showed a good sensitivity.Conclusion: CSS shows an acceptable reliability,validity and sensitivity in patients with stroke,but the predicative validity of CSS is inferior to that of NIHSS,which needs be further revised.

Objective:To explore the application and effect of the online teaching in the clinical nursing practice of obstetrics and gynecology during the coronavirus disease 2019 (COVID-19) epidemic.Methods:A total of 26 undergraduate nursing interns in the obstetrics and gynecology department of Xiangya Hospital of Central South University during the epidemic period were enrolled in this study. The interns accepted online practical teaching, and the teaching effect was analyzed and evaluated through the results of the exit examination and online teaching satisfaction.Results:The theoretical course scores of nursing students are all above 80 points, among which 22 (84.62%) are above 90 points. The operation scores are all above 90 (94.04±2.96) points. The results of the online teaching satisfaction survey show that, 23 (88.46%) nursing students are satisfied with the effect of their online practice.Conclusion:The online teaching mode during COVID-19 epidemic can help nursing students master the theoretical knowledge of obstetrics and gynecology, improve their clinical reasoning ability, strengthen their practical operation skills, and enhance their autonomous learning ability.

Lumbar spondylolysis is one of the common diseases of low back pain caused by spinal surgery. Its treatment options vary depending on different conditions, from early conservative ones to late surgical ones. There are still disputes over various conservative treatments, choice of surgical methods and the biomechanics of different internal fixation techniques to repair spondylolysis. Therefore, this review summarizes the clinical outcomes of previous clinical treatments of lumbar spondylolysis and the biomechanical characteristics of various techniques to find the mechanical and evidence-based clinical data that may facilitate the treatment of lumbar spondylolysis.

Objective: To explore the effect of nursing scheduling software combined with mobile phone APP in the nursing manpower arrangement in intensive care unit. Methods: The nursing scheduling software and mobile phone APP were applied to management resources of 82 nurses in ICU, substituted for traditional manual way. The work efficiency, nursing quality and nurse satisfaction were compared before and after implementing in intensive care unit. Results: After implementation of nursing scheduling software combined with mobile phone APP, the average time of scheduling was reduced from (6.49±0.62) h to (4.29±0.44) h, the difference was statistically significant (t=19.97, P<0.01). The nursing quality score was improved from (97.54±1.19) points to (95.16±1.29) points, the difference was statistically significant (t=-4.70, P<0.01). The nurses′ satisfaction about scheduling was improved from 73.2%(60/82) to 96.3%(79/82), the difference was statistically significant (χ²=17.04, P<0.01). Conclusions The mode of nursing scheduling software combined with mobile phone APP in intensive care unit has a good effect, which can improve the scheduling efficiency, the job satisfaction of nursing staff and the quality of nursing,and promote the nursing information management.
