ABSTRACT
Plant adaptation to adverse environment depends on transmitting the external stress signals into internal signaling pathways, and thus forming a variety of stress response mechanisms during evolution. Brassinosteroids (BRs) is a steroid hormone and widely involved in plant growth, development and stress response. BR is perceived by cell surface receptors, including the receptor brassinosteroid-insensitive 1 (BRI1) and the co-receptor BRI1-associated-kinase 1 (BAK1), which in turn trigger a signaling cascade that leads to the inhibition of BIN2 and activation of BES1/BZR1 transcription factors. BES1/BZR1 can directly regulate the expression of thousands of downstream responsive genes. Studies in the model plant Arabidopsis thaliana have shown that members of BR biosynthesis and signal transduction pathways, particularly protein kinase BIN2 and its downstream transcription factors BES1/BZR1, can be extensively regulated by a variety of environmental factors. In this paper, we summarize recent progresses on how BR biosynthesis and signal transduction are regulated by complex environmental factors, as well as how BR and environmental factors co-regulate crop agronomic traits, cold and salt stress responses.

Objective:To understand the quality of life of nurses and its influencing factors .Methods:Using WHOQOL-BREF scale and self-designed questionnaire , with the method of random , quota sampling , we chose 460 nurses in a county -level city of Shandong province to conduct the survey .Results:The environment field score was the highest (23.23 ±2.60), while the psychological score was the lowest (20.53 ±1.90).Nurses with higher ages scored lower in physiology and psychology .Male nurses ' physiology scores were higher than those of fe-males, but the psychological field scores of male nurses were lower .Those with higher education level scored lower in physiology .Physiological and psychological scores of administrative department nurses were higher .Scores of psychology , environment , and social relations were higher in permanent and high title nurses than those in contract and low (no) title nurses.Conclusion:It should establish the people -oriented nursing ethics culture , improve hu-man resource management .Through the standard post level management , flexible scheduling , we should improve the equal pay system , improve the sense of belonging , professional identity , to enhance quality of life .

ABSTRACT
Objective:To understand the quality of life about rural elderly population and its influencing factors.Methods:Using WHOQOL-BREF scale and self-designed questionnaire,a survey about quality of life was conducted among 1074 rural elderly in Shandong Province selected by stratified,random method.T test,variaace analysis and multiple linear regression were used to analyze the influencing factors.Results:The score of environment field was the highest (13.83 ± 1.05),while social relations field was the lowest (8.63± 0.45).Single factor analysis showed that age,education level,economic situation,pension source,chronic disease,pension mode,physical exanination had significant effect on quality of life scores in each dimension (P ＜ 0.05).Marital status only had significant effect on psychological and social relations scores (P ＜ 0.05).Gender and the number of children were not statistically significant on the quality of life score in each dimension (P ＞ 0.05).Multiple regression analysis showed that the influencing factors of quality of life score in each dimension were chronic disease and economic situation.Physical examination only had significant effect on the physiology and psychological score.Pension mode had significant effect on psychological and social relations score.Age influenced physiology health score.Marital status influenced psychology health score.Conclusion:The government should pay attention to the health status of elderly and the psychological status of elderly without spouse;increase the support efforts to the poor rural elderly;strengthen the prevention and treatment of chronic diseases;improve the social support network and social security system.
ABSTRACT
Objective To explore the influence of the health belief model education on the life quality of nurses.Methods 200 nurses were randomly divided into the experimental group and the control group with 100 cases in each,the experimental group received health belief model education while the control group was given no intervention.The life quality of nurses before and after the education was compared.Results The life guality of nurses showed no significant difference between the two groups before the health belief model education,one month after health belief model education,life quality of nurses in the two groups showed significant difference.Conclusions Application of the health belief model education can improve the nurses'quality of life.
