Objective: To analyze the influencing factors for the 20-69-year-old residents in Anhui Province with substandard physiques, so as to provide a basis for improving the physiques of population. Methods : The 2014 physical fitness survey data of residents aged 20-69 years in Anhui Province were collected, including demographic information, physical exercise status and physical indicators ( height, weight, vital capacity, blood pressure and so on ). The physiques of residents was rated according to the "National Fitness Standards" ( 2003 edition ) . The multivariate logistic regression model was used to analyze the influencing factors for substandard physiques in different age groups. Results: Among 39 803 residents recruited, 5 081 were rated as substandard physiques and the rate was 12.77%. The rates of substandard physiques in the residents aged 20-<40, 40-<60 and 60-69 years were 11.08%, 13.11% and 16.74%, respectively. The results of multivariate logistic regression analysis showed that age, gender, household registration, education level, occupation and time spent each exercise were the influencing factors for substandard physiques among the residents aged 20-<40 years ( P<0.05 ); age, household registration, education level, occupation and physical exercise were the influencing factors for substandard physiques among the residents aged 40-<60 years ( P<0.05 ); age, gender, education level, occupation, physical exercise and time spent each exercise were the influencing factors for substandard physiques among the residents aged 60-69 years ( P<0.05 ). Conclusions The residents aged 20-69 years in Anhui Province have higher rate of substandard physiques in the 2014 survey. Age, education level, occupation and physical exercise may affect physical fitness and vary in different age groups, thus interventions should be carried out according to age.

Objective To determine the impact of dental nurses′knowledge sharing behavior and self-efficiency on professional identity. Methods A total of 88 dental nurses in Xiangyang were tested by Professional Identity Inventory for Nurse,Knowledge Sharing Behavior Scale and General Self-efficacy Scale. Results The mean score of professional identity was (5.60 ± 0.56) points, the mean score of knowledge sharing behavior was (2.59 ± 0.77) points, the mean score of general self-efficacy was (2.66 ± 0.46) points. Knowledge sharing behavior and self-efficiency were positively correlated with professional identity(r=0.626, 0.342, P<0.01). Regression analysis showed that the organizational communications, communities of practice, written contributions and general self-efficacy could explain 54.3% of the variance for dental nurses′professional identity. Conclusions Nursing managers should focus on the shortcomings of dental nurses′ knowledge sharing behavior and general self-efficacy, and promote interventions to enhance dental nurses′knowledge sharing behavior and general self-efficacy and improve the level of professional identity.

IFN-gamma and TNF-alpha were co-coupled to the polystyrene cell culture plate by the photo-immobilization method. To investigate the synergistic effect of IFN-gamma and TNF-alpha on the HeLa cells, HeLa cells were treated with co-coupled cytokine or non-coupled cytokine in a time course in this study. The morphology detection, cell cycle analysis by flow cytometry, phosphatidyl serine analysis and capase-3 activity detection demonstrated that the two kinds of treatments both induce HeLa cells apoptosis. Non-coupled cytokine worked more quickly while co-coupled cytokine kept more permanent effect. The caspase-3 activity assay indicated that the caspase-3 activity of HeLa cells treated with non-coupled cytokine is higher than that of HeLa cells treated with co-coupled cytokine. This may imply that co-coupled cytokine not only induces the caspase-dependent pathway, but also induces the caspase-independent pathway.

Objective:To explore the influence of chronic rhinitis on depressive symptoms of college freshmen and the mediating effect of avoidant personality.Methods:A cluster sampling method was used to survey 8 079 college freshmen from April 2018 to October 2018 using the Beck depression inventory and the avoidant personality diagnosis questionnaire based on DSM-Ⅳ.SPSS 25.0 software was used for descriptive statistics and Spearman correlation analysis, and the macro program PROCESS version 3.3 was used for the mediating effect.Results:(1) The detection rates of chronic rhinitis, avoidant personality and depressive symptoms were 22.90% (1 850/8 079), 19.22% (1 553/8 079) and 6.28% (507/8 079). The scores for avoidant personality disorder and depressive symptoms were 1.00 (0, 3.00) and 1.00 (0, 4.00), respectively. (2) The chronic rhinitis, avoidant personality and depressive symptoms were positively correlated ( rchronic rhinitis-avoidant personality=0.094, rchronic rhinitis-depressive symptoms=0.095, ravoidant personality-depressive symptoms=0.416, all P<0.001). (3) Chronic rhinitis could positively predict depressive symptoms ( β=1.113, P<0.001). (4) Avoidant personality played a mediating role between chronic rhinitis and depressive symptoms ( β=1.094, P<0.001), and accounted for 44.92%(0.500/1.113) of the total effect. Conclusion:Chronic rhinitis directly affect the depressive symptoms of college freshmen, and indirectly affect the depressive symptoms of college freshmen through the mediating role of avoidant personality.

Objective:To explore the application of micro-lecture system based on ASSURE model in clinical practice teaching of dermatology.Methods:Sixty clinical medicine undergraduate intern doctors in Batch 2014 of Anhui Medical University were randomized into 2 groups, with thirty interns in both experimental group and control group. Micro-lecture system based on ASSURE model teaching method was adopted in experimental group, while traditional teaching method was adopted in control group. At the end of practice, theory test scores and medical record writing was used to evaluate the clinical ability of interns in two groups, and questionnaire survey was conducted to evaluate the satisfaction of interns with the teaching method of micro-lecture system based on ASSURE model. SPSS 16.0 was used for t test. Results:①Theory test scores were higher in experimental group than in control group, with statistically significant differences between the two groups ( P<0.05); ②The scores of history of illness, physical examination, treatment plan and the medical record writing were higher in experimental group than in control group ( P<0.05); ③At the end of internship, the questionnaire showed that the interns in the experimental group were more recognized for this new way of teaching. Conclusion:Micro-lecture system based on ASSURE model teaching method has achieved better results in the teaching of dermatology, which is worthy of future research and promotion.
