The cell-free plasma DNA of the 132 critically ill patients admitted to the emergency intensive care unit ( EICU) was measured by real-time quantitative polymerase chain reaction assay for the humanβ-globin gene. Ac-cording to the prognosis, the patients were divided into survival group (95 cases) and death group (37 cases). Blood samples were collected after EICU admission, 24 hours after admission, 48 hours after admission, and 1 week after admission. 30 age-mached controls were collected from healthy volunteers healthy care centre. Com-pared with control group, at each time point, cell-free plasma DNA concentration was significantly higher in EICU patients (P<0. 05). Cell-free plasma DNA concentrations were higher in hospital non-survivors than in survivors, of which plasma DNA concentration of 24 hours after admission and 48 hours after admission was statistically signifi-cant ( P<0 . 05 ) . The area under the ROC curves ( AUC ) for plasma DNA was bigger than the lactate and A-PACHE IIscore, the maximum of AUC was 0. 847(95% CI 0.648~1.000) at the point of 48 hours after admis-sion.

Objective:To investigate the status of core competency of newly recruited nurses in Traditional Chinese Medicine (TCM) hospitals during the standardized training period and explore its influencing factors.Methods:From March to April 2018, new recruits of nurses from various levels of TCM hospitals in 11 provinces or municipalities directly under the central government were selected to conduct a questionnaire survey, and the results of the survey were statistically analyzed.Results:728 questionnaires were actually recovered, including 723 valid questionnaires. The total score of the core competency of newly recruited nurses in the standardized training period of the TCM hospital is (160.42±37.25) . The results of single factor analysis showed that the differences in core competency scores of nurses with different educational backgrounds, graduated colleges and working stages were statistically significant ( P<0.05) . Correlation analysis showed that the scores of occupational identity of newly recruited nurses in TCM hospitals were positively correlated with the scores of core competency ( P<0.05) . Multiple linear regression analysis showed that the types of colleges, academic qualifications, working stages, and the sense of selfdetermination, self-efficacy, Sense of organizational influence, consistency in the occupational identity were the influencing factors of nurses' core competency ( P<0.05) . Conclusions:The core competency of newly recruited nurses in TCM hospitals is affected by the types of colleges, academic qualifications, working stages, and the sense of self determination, self-efficacy, sense of organizational influence, consistency in the occupational identity. Targeted measures should be taken to improve the core competency and professional identity of newly recruited nurses, so that can enhance the cohesion of the nursing team and improve the overall level of nursing.
