BACKGROUND:Cytokines and neurotrophic factors secreted from human umbilical cord blood-derived mesenchymal stem cells secrete have neuroprotective effects on cerebral ischemia-reperfusion injury, but there are few reports about intranasal administration of human umbilical cord blood-derived mesenchymal stem cellconditioned medium in the treatment of stroke.
OBJECTIVE:To investigate the protective effects of intranasal administration of human umbilical cord-derived mesenchymal stem cells-conditioned medium on neurologic function of rats with cerebral ischemia-reperfusion injury.
METHODS:Adult rats were subjected to 2 hours of right middle cerebral artery occlusion and the human umbilical cord-derived mesenchymal stem cells were isolated from the postpartum human cord. We made the conditioned medium of human umbilical cord-derived mesenchymal stem cells. Ischemic rats were randomized and assigned to three groups and were treated by intranasal routine starting 24 hours after middle cerebral artery occlusion with:(1) saline for control group;(2) Dulbecco’s modified Eagle’s medium/Ham’s nutrient mixture F-12 medium for medium control group;(3) conditioned medium treatment group (10mL/kg) daily for 14 days. Behavioral tests (foot fault test, and modified Neurological Severity Score) were performed before and at 1, 7, 14 days after middle cerebral artery occlusion.
RESULTS AND CONCLUSION:There was no difference in the behavioral tests among the three groups at postoperatively 1 day (P>0.05). Compared to the control and medium control group rats, respectively, rats in the conditioned medium group significantly improved functional outcome after stroke in days 7 and 14 (P<0.05). There was also no significant difference in functional tests between the control group and medium control group in days 7 and 14 (P>0.05). These results suggest that human umbilical cord-derived mesenchymal stem cells-conditioned medium via intranasal administration can significantly improve neurologic functional outcome after cerebral ischemia-reperfusion injury.

Objective:To explore the relationship between the health literacy of employees and smoking, drinking, diet and exercise, and provide scientific basis for health education and targeted intervention.Methods:From February to July 2019, a cluster random sampling method was adopted to select enterprise employees in Shihezi City to conduct a questionnaire survey. Self-made questionnaires and "National Resident Health Literacy Monitoring Questionnaire" were used to assess the social demographics, health literacy, and Health-related behaviors were investigated, and 1053 valid questionnaires were collected. Logistic regression model was used to analyze the relationship between health literacy and the three dimensions with smoking, drinking, diet and exercise.Results:Total score of health literacy of enterprise employees is (42.06±11.03) points and the employee health literacy rate of Shihezi City in 2019 is 19.47%. Univariate analysis showed that non-smokers had higher health literacy and three-dimensional health literacy availability than smokers ( P<0.01) ; fewer drinkers had higher health literacy availability than overdrinkers ( P<0.05) ; balanced diet health literacy availability The health literacy availability rates in the three dimensions were higher than those in the unbalanced diet ( P<0.01) . In the logistic regression analysis, healthy lifestyle and behavioral literacy were independently related to smoking behavior ( OR=1.571, P<0.05) ; the presence of health literacy and the three dimensions of health literacy were not statistically related to alcohol consumption ( P>0.05) ; there is a statistical correlation between health literacy, healthy lifestyles, behaviors, and health skills and regular exercise among employees ( OR=1.829、2.503、1.395, P<0.05) ; employees with health literacy and three dimensions of health literacy are more likely to have a balanced diet ( P<0.01) . Conclusion:There is a correlation between the health literacy of enterprise employees and diet and exercise. The improvement of health literacy level is an important way to interfere with unhealthy behaviors.
