Objective To investigate health behavior level and self-efficacy in patients underwent coronary artery stent implantation,and to discuss the relationship between health behavior and self-efficacy and to offer proof to the intervention strategy of health behavior.Methods HPLP Ⅱ,self-efficacy questionnaire were used as main tools.106 patients underwent coronary artery stent implantation were investigated.Statistics analyses were performed using the Statistical Package for Social Science(SPSS)13.0.Results (1)The score of total HPLPⅡwas 130.08±21.25,the range of that was 84～180.The health behavior level of47.2%patients was general or worse,and that of 52.8%patients was good or better.(2)The score of self-efficacy was 71.37±16.32,the range of thatwas 38～110.(3)There were significant positive relationship in the scores of total HPLP Ⅱ and the six elements,and self-efficacy.The correlation coefficient was 0.389～0.916(P＜0.01).Conclusion The health behavior level of patients underwent coronary artery stent implantation was not in an ideal state.Self-efficacy has a positive effect on health behavior.The importance motivating factor should be attached to nursing practice and education by medical staff,and medical staff should establish and supervise to carry out corresponding intervention measure.

Objective To investigate characteristics of emotional intelligence(EI)and the ways of occupational stress coping in nurses as well as the predictive validity of EI on coping strategies.Methods 464 nurses from general hospitals were collected and evaluated with psychometric instruments including:Wong's Emotional Intelligence Scale(WEIS)and Nurse Ways of Coping Questionnaire.Data were conducted by Logistic regress analysis according to key themes.Results (1)Nurses' demographic characteristics had effects to the ways of occupational stress coping and emotional intelligence.However,there was no statistical difference of El varied with education levels(P＞0.05).(2)Both problems solving and positive recognition are main coping styles of nurses towards occupational stress.Either avoidance or self-reproach was seldom coping strategies of nurses toward occupational pressures(2.60±0.55;2.60±0.75;1.37±0.69;respectively).(3)El was correlated with coping styles(r=-0.123～0.253,P＜0.05,P＜0.01).Conclusion Four dimensions of EI positively or negatively predicted six kinds of occupational stress coping strategies separately.

Objective To investigate the cognition of falling from doctors,nurses and patients in eight Chongqing local hospitals,and develop targeted health education to prevent the occurrence of falling events.Methods Based on data analysis of 368 falling cases from eight Chongqing local hospitals,a selfdesigned questionnaire was developed and used to investigate doctors,nurses and patients from these eight hospitals.1 393 questionnaires were returned,with a recovery rate of 97.69％.The method of t test,analysis of variance and Chi Square （x2) test were used for analysis.Results Nurses had highest recognition for falling features,doctor followed,patients with the lowest,the differences had statistical significance; Nurses' cognitive degree from Third-Grade A-Level hospital was above that of nurses from Second-Grade A-Level hospital,the differences had statistical significance; Doctors' cognition of hospitalization days when falling and susceptible population of falling was lower than that of nurses.Nurses thought falling tended to occur from nightfall to midnight.Conclusions Survey found that,the cognitions of falling from doctors,nurses and patients were different from actual results.Cognition were also different among three sides of them,according to the survey results,health education for different objects should be provided,raise everyone's awareness,thus using targeted falling prevention measures to reduce the incidence of falling.

BACKGROUND:The development of tissue engineering techniques provides new methods and ideas for the repair and functional reconstruction of articular cartilage defects.
OBJECTIVE:To summarize the research progress in the application of mesenchymal stem cel s, as seed cel s, in articular cartilage tissue engineering.
METHODS:A computer-based retrieval was performed to search articles describing articular cartilage tissue engineering and mesenchymal stem cel s published between January 1st, 2000 and September 30th, 2014 in PubMed database with the key words of“articular cartilage defects;cartilage tissue engineering;mesenchymal stem cel s”in English. Seventy articles were retrieved initial y, and only 49 were included in further analysis.
RESULTS AND CONCLUSION:The ability of the articular cartilage for defect self-repair is limited, and current clinical treatments cannot be satisfactory. Development of tissue engineering provides a new idea for problem-solving. In the selection of seed cel s, chondrocyte is limited to dedifferentiate, and embryonic stem cel is restricted by ethical, legal and other aspects. Autologous mesenchymal stem cel s, which are easy to be amplified
and exhibit excel ent cartilage differentiation potential, have gained widespread attention. But there is stil some controversy on the current application of tissue engineering techniques for repair of articular cartilage defects, including a certain gap between the long-term effects and the clinical applications. So the effect of mesenchymal stem cel s on biological structure and mechanical function stil needs further studies.
