Objective To study the development of self-concept and parental rearing style in primary and secondary school students and the relationship between them.Methods A stratified cluster sample of 319 students from fourth grade in primary school to first grade in high school,9～16 years of age,were investigated with the Piers-Harris Children's self-concept Scale (PHCSS) and the EMBU.Results Inter-grade differences existed in the total score of self-concept and its subscales except popularity (F=2.170～4.288,P＜0.05),as well as in the most factors of parenting except father's intrusiveness,father's overprotection,mother's intrusiveness and overprotection,and mother's punishment (F=2.449～7.596,P＜0.05),with the maxima of self-concept (total score 61.05±9.00,behavior 13.85±1.94,intellect status 11.48±3.10,physical appearance 8.33±2.50,lack of anxiety 10.13±2.39,happiness 8.38±1.23) and the minima of father's punishment and rejection and mother's rejection (15.08±2.80,7.33±2.23,10.43±3.26) both in the sixth grade pupils (P＜0.05).Parental emotional warmth was positively correlated to self-concept (r=0.188～0.389),while parental punishment and mother's rejection was negatively correlated to (r=-0.112～-0.540),and father's rejection was also negatively correlated to (r=-0.160～-0.420) except physical appearance.All of these correlations were significant (P＜0.05).Conclusion Self-concept of primary and secondary school students and parental rearing style interact with each other,and develop curvily with children's growing.

We built a new platform based on teaching experiences and difficulties of applied psychology in Hunan University of Chinese Medicine.The new platform was built aiming at improving curriculum,establishing practice platform,reforming assessment methods and constructing supervising mode between teaching and studying.The new multi-leveled and multi-layered practice platform,starting from the mental health screening of freshmen,was consisted of levels of practice operations including mental health record-mental health assessment-psychological consult and therapy.

Objective To investigate the impact of negative perfectionism on negative emotion(anxiety,depression) and the moderating effects of positive perfectionism.Methods A study was designed and a sample of 380 college students completed questionnaires including PANPS,SAS and SDS.Results ① Correlation analysis indicated positive perfectionism was negatively correlated with anxiety and depression (r1 =-0.25,P1 ＜0.01,r2 =-0.29,P2＜0.01),while negative perfectionism was positively correlated with anxiety and depression(r1 =0.26,P1 ＜0.01,r2 =0.22,P2＜0.01).② Moderating effects analysis indicated that positive perfectionism significantly moderated the regulating effect of negative perfectionism upon negative emotions(anxiety,depression) (β 1 =-2.64,β2 =-7.67,P＜0.01).Conclusion These findings suggest that the higher level of positive perfectionism,the greater influence of perfectionism on depression and anxiety,and positive perfectionism could buffer the negative perfectionism on anxiety and depression.

Objective To explore the character of ruminant thinking individuals in cold executive functions(cool EF) and hot executive functions(hot EF).Methods According to the score of rumination response scale( RRS) ,17 low-level ruminant thinking individuals and 21 high-level ruminant thinking indi-viduals were screened out and finished the classic Stroop test.Results In the cool EF,it was consistent be-tween low-level and high-level ruminant thinking individuals for color naming task response time ((10.61± 23.20)ms vs (10.79±29.32)ms),and there was no significant difference in the classic Stroop test( t=0.21, P>0.05) .In the hot EF,the respone time of the low-level group was longer than that of high-level group on the positive and negative((-5.01±22.20)ms vs (-10.88±20.33)ms;(8.78±29.96)ms vs (-8.68±19.94) ms) ,and the main effect of the emotional Stroop interference scores between positive and negative words was highly significant(F=10.88, P<0.05) .The interactive effect of emotional Stroop interference scores of words × subjects was significant(F=5.70, P<0.05) .The simple effect tests showed that the emotional Stroop interfer-ence scores between high-level and low-level ruminant thinking subjects were significant in the negative group(F=4.69, P<0.05) .And it was also significant between positive and negative words in the low-level group(F=14.63, P<0.05).Conclusion Two types of subjects in the cold EF have no significant difference. High-level ruminant thinking individuals in the cold EF are normal,but impaired in the hot EF that meaning high-level ruminant thinking individuals had bias to negative emotion.These results provide new clues for the intervention of negative emotions caused by ruminants.

Objective:To develop a risk prediction model for identifying bronchopulmonary dysplasia (BPD) associated pulmonary hypertension (PH) in very premature infants.Methods:This was a retrospective cohort study. The clinical data of 626 very premature infants whose gestational age <32 weeks and who suffered from BPD were collected from October 1 st, 2015 to December 31 st, 2021 of the Seventh Medical Center of the People′s Liberation Army General Hospital as a modeling set. The clinical data of 229 very premature infants with BPD of Hunan Children′s Hospital from January 1 st, 2020 to December 31 st, 2021 were collected as a validation set for external verification. The very premature infants with BPD were divided into PH group and non PH group based on the echocardiogram after 36 weeks′ corrected age in the modeling set and validation set, respectively. Univariate analysis was used to compare the basic clinical characteristics between groups, and collinearity exclusion was carried out between variables. The risk factors of BPD associated PH were further screened out by multivariate Logistic regression, and the risk assessment model was established based on these variables. The receiver operating characteristic (ROC) area under curve (AUC) and Hosmer-Lemeshow goodness-of-fit test were used to evaluate the model′s discrimination and calibration power, respectively. And the calibration curve was used to evaluate the accuracy of the model and draw the nomogram. The bootstrap repeated sampling method was used for internal verification. Finally, decision curve analysis (DCA) to evaluate the clinical practicability of the model was used. Results:A total of 626 very premature infants with BPD were included for modeling set, including 85 very premature infants in the PH group and 541 very premature infants in the non PH group. A total of 229 very premature infants with BPD were included for validation set, including 24 very premature infants in the PH group and 205 very premature infants in the non PH group. Univariate analysis of the modeling set found that 22 variables, such as artificial conception, fetal distress, gestational age, birth weight, small for gestational age, 1 minute Apgar score ≤7, antenatal corticosteroids, placental abruption, oligohydramnios, multiple pulmonary surfactant, neonatal respiratory distress syndrome (NRDS)>stage Ⅱ, early pulmonary hypertension, moderate-severe BPD, and hemodynamically significant patent ductus arteriosus (hsPDA) all had statistically significant influence between the PH group and the non PH group (all P<0.05). Antenatal corticosteroids, fetal distress, NRDS >stage Ⅱ, hsPDA, pneumonia and days of invasive mechanical ventilation were identified as predictive variables and finally included to establish the Logistic regression model. The AUC of this model was 0.86 (95% CI 0.82-0.90), the cut-off value was 0.17, the sensitivity was 0.77, and the specificity was 0.84. Hosmer-Lemeshow goodness-of-fit test showed that P>0.05. The AUC for external validation was 0.88, and the Hosmer-Lemeshow goodness-of-fit test suggested P>0.05. Conclusions:A high sensitivity and specificity risk prediction model of PBD associated PH in very premature infants was established. This predictive model is useful for early clinical identification of infants at high risk of BPD associated PH.
