Objective To investigate the clinical and neuroimage characteristics of reversible posterior leukoencephalopathy syndrome (RPLS) in Chinese elderly patients. Methods The characteristic clinical presentation and neuroimaging of 5 elderly patients with RPLS were retrospectively analyzed. Results There were one male and four females in this study, with the average age of (63.0±2.4) years, all combined with hypertension. The most common clinical presentations were abnormality of visual perception (5 cases), headache (4 cases), epileptic seizure (4 cases), disturbance of consciousness (3 cases), pathological reflex (2 cases) and hemiplegia (2 cases). CT scan showed 4 cases with low density lesions. MR1 scan showed 5 cases with occipital lobe lesions, 2 with parietal lobe lesions and 1 with temporal lobe lesions. Re-examination of CT scans showed that 4 survived patients became normal at mean (48.8±29.2) days after discharging from hospital. Conclusions The etiologies of RPLS are diverse. The vasogenic theory is supported by neuroimage of RPLS. Neuroimage may be very important for the diagnosis of RPLS. Diffusion-weighted imaging and apparent diffusion coefficient map may be helpful for differential diagnosis between RPLS and cerebral infarct.

Objective:To explore the effect of STEM (science, technology, engineering, mathematics) education in the teaching of Comprehensive Nursing Practice course, which is integrated with the concept of social work. Methods:The course of Comprehensive Nursing Practice integrated with the concept of social work was constructed, and two classes of Batch 2019 nursing undergraduates in our university were selected as the research objects, including 46 students in the control group which took traditional teaching, and the other 43 students in the research group which took STEM teaching. Both groups were taught for 2 months (28 class hours). The teaching process, teaching summary and teaching satisfaction of the two groups were evaluated. SPSS 25.0 was used for t-test, Chi-square test and rank-sum test. Results:The scores of STEM literacy, practical ability, inquiry consciousness, learning condition, participation and enthusiasm in the research group were higher than those in the control group ( P < 0.05). After teaching, the scores of problem-solving ability, work display and theoretical knowledge of the research group were higher than those of the control group ( P<0.05). The students in the research group were more satisfied with teaching than those in the control group ( P<0.05). Conclusion:The construction of Comprehensive Nursing Practice course with the concept of social work and the application of STEM education can improve students' learning ability, learning effect and their satisfaction with the course teaching.

Objective To study the application effect of quality control circle(QCC)in reducing the dissatisfaction rate of physical examination clients in health management center.Methods To establish QCC,selected the health check-up popula-tion in our hospital in September-2019 and March-2020,through the questionnaire investigation and analysis,compare the dis-satisfaction of the clients before and after the quality control circle.Results After carrying out QCC activities,the dissatisfaction of physical examination clients was significantly lower than that before QCC,and the difference was statistically significant(P＜0.05).Conclusion The activities of QCC in the health management center can effectively improve the quality of the physical examination work and reduce the dissatisfaction of the customers in the physical examination.It is of great significance to the health management.
