Objective:To understand the quality of life of high risk population of stroke in community and analyze the influencing factors.Methods:Four community health service centers in Huangpu District were randomly selected, and the subjects were included by using convenient sampling method among the high risk groups of stroke found in the community stroke screening and prevention and control project in Shanghai.The World Health Organization quality of life scale-brief form questionnaire(WHOQOL-BREF), self-rating depression scale (SDS) and self-rating anxiety scale (SAS) were used as the survey tools to study 1200 high-risk stroke subjects.Single sample t-test was used to compare the differences between the scores and the data of 24 centers in the world, and multiple linear stepwise regression were used to analyze the influencing factors. Results:The scores of physical field, psychological field and social relationship field ((13.60±1.86), (14.58±1.97), (13.72±2.10)respectively) of high-risk population of stroke were lower than the scores of general population of 24 centers in the world ( P<0.01), and the scores of environmental field (14.08±1.95) were higher than it ( P<0.01), of which the differences were all statistically significant.The results of multiple linear stepwise regression analysis showed that old age, anxiety and depression were the risk factors influencing the scores of physical field( β=-0.027, -0.056, -0.051), psychological field( β=-0.019, -0.055, -0.050) and environmental field( β=-0.017, -0.040, -0.054); old age and depression were the risk factors influencing the scores of social relationship field( β=-0.026, -0.067); anxiety and depression were the risk factors influencing the self-assessment of quality of life and health ( β=-0.012, -0.014 for quality of life; -0.012, -0.014 for health, all P<0.01). Conclusion:The quality of life of high-risk population of stroke may be related to age, depression, anxiety and other psychological factors.The prevention and treatment of stroke should take both physical and mental measures, take timely intervention for poor psychological status, and gradually improve the quality of life.

OBJECTIVE: To explore the relationship between allogeneic transfusion and hospital infections in patients with closed traumatic brain injury in the perioperative period.
 METHODS: The clinical data of 181 patients with open brain surgery suffering closed brain injury in Changsha Central Hospital from February, 2012 to December, 2013 were retrospectively collected. The patients were divided into a mild and moderate brain injury group (n=83) and a severe brain injury group (n=98) according to evaluation system of Glasgow coma scale (GCS). They were also divided into a autologous transfusion plus mild and moderate brain injury group (n=14), a autologous transfusion plus severe brain injury group (n=10); an allogeneic transfusion plus mild and moderate brain injury group (n=31), an allogeneic transfustion plus severe brain injury group (n=70); a non-transfusion plus mild and moderate brain injury group (n=38) and a non-transfusion plus severe brain injury group (n=18) according to the transfusion styles. The hospital infection of all the patients was examined.
 RESULTS: The rate of hospital infection was significantly higher in the severe brain injury group than that in the mild and moderate brain injury group (P<0.05). The rate of post-operative hospital infection in the allogeneic transfusion plus severe brain injury group was also significantly higher than that in the autologous transfusion plus severe brain injury group (P<0.05). Similarly, the rate of post-operative hospital infection in the allogeneic transfusion plus mild and moderate brain injury group is higher than that in the non-transfusion plus mild and moderate brain injury group (P<0.05).
 CONCLUSION The allogeneic transfusion at perioperative period may be one of the risk factors for post-operative hospital infection in the closed brain injury patients. The more severe the injury is, the higher risk the hospital infection will be.
