The mediating role of psychological resilience to childhood abuse and binge eating among middle school students / 中华预防医学杂志

To explore the mediating role of psychological resilience to childhood abuse and binge eating. This study assessed the childhood abuse, binge eating and psychological resilience of 3 453 middle school students in Harbin city, Heilongjiang Province. SPSS PROCESS macro program, combined with Bootstrap method, was employed to explore the mediating effect of psychological resilience. The incidence of middle school students experiencing at least one type of abuse in their childhood was 81.3% (2 807/3 453). Childhood abuse, psychological resilience and binge eating were all significantly different in terms of gender, household registration and whether they were only child (all P values<0.05). There was a significant positive correlation between childhood abuse and binge eating. Psychological resilience was negatively associated with childhood abuse and binge eating. Childhood abuse could not only directly predict the binge eating behavior of adolescents, but also could indirectly affect it via psychological resilience.

Current status of professional identity among undergraduates majoring in public affairs management and the related influencing factors / 中华医学教育探索杂志

Objective@#To investigate the current status of professional identity among the undergraduates majoring in public affairs management and the related influence factors.@*Methods@#A stratified cluster sampling method was used to conduct a questionnaire survey among the 115 undergraduates majoring in public affairs management in a medical university in Harbin, China, and the contents of the questionnaires included general status and professional identity. The t-test, one-way analysis of variance, and multiple linear regression analysis were used to analyze the influencing factors of professional identity. In-depth interviews were conducted for some students to explore the profound influencing factors for professional identity among the students majoring in public affairs management.@*Results@#The overall level of professional identity was low among the undergraduates majoring in public affairs management in the medical university in Harbin, and the score of professional identity was 3.25±0.56. The scores of cognitive dimension, emotional dimension, behavioral dimension, and applicable dimension were 3.41±0.69, 3.21±0.78, 3.24±0.71, and 3.13±0.72, respectively. The multivariate analysis showed that grade, academic performance, major selection, and children number in family had significant influence on their professional identity. The students who were at grade four, who had high academic record (b=-0.276, P<0.01), who chose this major independently (b=-0.277, P<0.01), and who were the only child (b=-0.233, P<0.05) had a high score of professional identity. As for the undergraduates at different grades, the undergraduates at grades two and three had a significantly lower score of professional identity than those at grade four (b=-0.296 and -0.369, P<0.05), while there was no significant difference between the undergraduates at grades one and four (b=-0.008, P>0.05). Furthermore, the students with a high score of professional identity had higher possibility to pursue the job related to this major than those with a low score (3.39±0.53 vs. 2.92±0.49, t=4.414, P<0.01).@*Conclusion@#Universities should strengthen the publicity of the major of public affairs management, optimize the curriculum, and add job experience, so as to enhance professional identity among students with this major and provide talent for the field of public health management.

Comparative study on effects of tobacco control curriculum in different major students / 中华医学教育探索杂志

Objective To compare the impact of tobacco control curriculum on self-efficacy of tobacco control in different major of public health students, and offer theoretical foundation for improving tobacco control curriculum.Methods We offered tobacco control curriculum for 150 public health students (including students of preventive medicine and public service administration research direction) in medical university of Harbin, and investigated twice general self-efficacy, smoking selfefficacy and tobacco control self-efficacy before and after tobacco control curriculum, then compared intervention effects between two major students by t test.Results There were no differences of tobacco control self-efficacy, smoking self-efficacy and general self-efficacy between two major students, t values were-0.832 (P=0.407), 0.190 (P=0.849) and-0.492 (P=0.624).The tobacco control self-efficacy (t=-3.566, P=0.001) and general self-efficacy (t=-2.237, P=0.028) increased remarkably but smoking self-efficacy (t=-1.102, P=0.273) in preventive medicine students after intervention.And all of three kinds of self-efficacy were not gotten better by intervention in public service administration students.There was no obvious difference of intervention effects between tobacco control self-efficacy and general self-efficacy among preventive medicine students (t=1.541, P=0.125).Conclusions The improvement of preventive medicine students by tobacco control curriculum is better than that of public service administration students.We should further perfect the tobacco control course, and on the one hand, improve the intervention effect of students majoring in course of public health management;on the other hand, strengthen the target effects of the tobacco control curriculum to students' tobacco control self-efficacy and smoking self-efficacy.

Evaluation on efficacy of different doses of propranolol in treatment of infantile hemangioma / 吉林大学学报(医学版)

Objective To investigate the clinical effects of different doses of propranolol in treatment of infantile mixed and deep hemangioma,and to provid theoretical and experimental evidence for the treatment of hemangioma. Methods The selected 62 patients with mixed and deep hemangioma were divided randomly into low dose (1.5mg·kg-1 ·d-1 )and high dose (3.0 mg·kg-1 ·d-1 )of propranolol groups,3 times a day,6 months as a course,the changes in hemangioma size and the incidence of adverse reactions were recorded.Results The efficacy was evaluated using Achauer system.The total effective rate was 80.65% in low dose of propranolol group and 93.55% in high dose of propranolol group,including 6 cases of class Ⅰ (poor),9 cases of class Ⅱ (moderate), 11 cases of classⅢ (good),and 5 cases of class Ⅳ (excellent)in low dose propranolol group;while 2 cases of class Ⅰ (poor),4 cases of class Ⅱ (moderate),10 cases of class Ⅲ (good)and 15 cases of Ⅳ (excellent)in high dose of propranolol group.The efficacy in high dose of proprandol group was significantly better than that in low dose of proprandol group (P0.05)and there was no significant difference in the incidence of adverse reaction between two groups (P>0.05).Conclusion The efficacy of oral 3.0 mg·kg-1 ·d-1 propranolol in treatment of infantile mixed and deep hemangioma is increased significantly, and there is no significant adverse reactions after increasing doses.Therefore,high dose of propranolol should be recommended in order to improve the therapeutic effect.

Objective:To explore auditory event-related P300 in children with behavior problems. Methods: 40 children with behavior problems were screened out from a ample of pupils by CBCL and CRT-C 2. The control group was selected from the others matched by age and gender, the rate of case/control was 1:2. The study and control group were assessed by auditory event-related P300 elicited by pure tone stimuli using the oddball paradigm.Results:(1) There was no significant difference in P300 between study and control groups; (2) The P300 latency of mixed problem group were significantly longer than those of controls. (3) The P300 amplitude were significantly negatively correlated with the CBCL score.Conclusion:It is suggested cognitive function deficit of severe behavior problem children.
