To analyze the mortality risk of stroke in China by literature search.The mortality rate of stroke (age standardized) in China has declined in recent years.The mortality rate of stroke which increases with age is higher in rural areas than in urban areas,and is higher in men than in women in China.There are obvious regional differences and seasonal differences in the mortality of stroke in China.Different subtypes of stroke have different death characteristics.Low or high temperatures can increase the risk of mortality of stroke.With the change of epidemiological characteristics,the risk factors of mortality of stroke in China are also changing.Through the epidemiological study of stroke death,the mortality risk of stroke can be researched effectively,the epidemiological characteristics of stroke can be mastered,and the direction of prevention and treatment of stroke can be understood.Individualized and multi factor intervention for unhealthy lifestyle,unhealthy behavior and metabolic cardiovascular risk factors can promote the establishment of stroke prevention and control strategy in China.

Objective To study the relationship between sensation seeking,personality characteristics and health-risk behaviors of medical freshmen.Methods Sensation Seeking Scale ( SSS),Eysenck Personality Questionnaire( EPQ),Adolescent Health-Risk Behaviors Questionnaire were applied in this survey to 384 freshmen from two medical colleges.Results ① The health risk behaviors were comnmon in the medical college freshmen (5.2％,48.2％ ),and the score of health risk behaviors had a significant difference between boys and girls,boys risk behaviors were much more than girls(P＜ 0.05 ).②The correlations between the risk behaviors (such as smoking,drinking,fighting,suicidal ideas,using internet too long,poor eating behavior,lack of physical exercise) and sensation seeking personality traits were strong.The health-risk behaviors were all correlated with extraversion(E)and neuroticism (N) significantly( 66.78 ± 10.29 vs 60.57 ± 9.09,t =2.54,P ＜ 0.01 ;7.11 ± 3.23 vs 5.33 ±2.89,t =2.81,P ＜ 0.05 ).③The results of logistic regression analysis showed that male mother' s high education level,sensation seeking,Eysenck' s P,N dimension were effective prediction factors of freshmen ' s health-risk behaviors.Conclusion Medical college freshmen who have higher levels of sensation seeking,Eysenck' s P,N dimension are more prone to health risk behaviors.

Objective: To analyze the trend of citation index of Chinese Journal of Behavioral Medicine and Brain Sciences(CJBMBS) from 2011 to 2018, and compare to the average level of Chinese Medical Association(CMA) series journals, so as to provide basis for improving academic quality and journal influence. Methods: Trend analysis on citation index of CJBMBS from 2011 to 2018 and comparison with the average level of Chinese Medical Association series journals were conducted by Microsoft Excel 2010. Results: From 2011 to 2018, the core impact factor(0.849-1.151) and ratio of foundation-supported papers(0.550-0.810) of CJBMBS showed an upward trend, while the core total citation(1 783-2 836) showed a downward trend.The core total citation, core impact factor and ratio of foundation-supported papers of CJBMBS were higher than the average level of CMA series journals(1 355-1 699, 0.497-0.890, 0.335-0.460), but the core other-citation rate was lower than the average level of CMA series journals (0.81-0.85). Conclusion The CJBMBS is at a high level among the core journals of Chinese science and technology, and more attention should be paid to the problem of high self-citation rate.
