Objective: To compare the difference of self-concept between children of complete and divorced family. Methods: 42 subjects in divorced family and 45 controls were tested by Piers-Harris Self-concept Scale for Children. Rusults: The students in divorced family reported significantly lower scores on self-concept than the controls on behavior,anxiety, gregariousness, satisfaction and total score. Conclusion: The self-concept of divorced family students is lower than that of the control group.

Objective To investigate the relationship between general self-concept, social support and subjective well-being in Chinese older adults.Methods A total of 717 older adults completed the Gen-eral Self-Concept Scale ( GSCS) ,Social Support Rating Scale( SSRS) and Memorial University of Newfound-land Scale of Happiness(MUNSH).Results The self-concept score of the elderly was (2.91±0.41),social support score was (35.45±7.12) and subjective well-being score was (11.56±10.31).Social support was sig-nificantly positively related with self-concept and subjective well-being ( r=0.43,P<0.05;r=0.17,P<0.05) . Self-concept played a partly mediating role between social support and subjective well-being,and the confi-dence interval from Bootstrap output were 95％ (0.22,0.78).The mediating effect between social support and subjective well-being were suppressing effects( direct effects|-0. 31|, indirect effects |0. 50|>total effects|0.19|).Conclusion Social support can indirectly affect subjective well-being through self-concept.

Objective     To investigate the risk factors for postoperative complications Clavien-Dindo classification≥grade Ⅱ after lung cancer surgery. Methods     The patients who underwent lung cancer surgery in a multicenter observational study from November 2017 to January 2020 were included. The Clavien-Dindo classification of postoperative complications was analyzed. Logistic regression was used to identify the risk factors for complications≥ gradeⅡ. Results     A total of 388 patients were enrolled, including 203 males and 185 females with a mean age of 56.14±10.36 years. The incidence of postoperative complications was 25.52% (99/388) after lung cancer surgery and the incidence of complications≥gradeⅡ was 20.10% (78/388). The five most common postoperative complications were pneumonia (6.96%), prolonged pulmonary air leak (>7 days, 5.67%), incision dehiscence (4.64%), arrhythmia (3.87%), and postoperative pleural effusion (3.35%). Multivariate analysis showed that open surgery [reference: uniportal thoracoscopic surgery, OR=2.18, 95%CI (1.01, 4.70), P=0.047], extended resection [reference: sublobar resection, OR=2.86, 95%CI (1.11, 7.19), P=0.030; reference: lobectomy, OR=2.20, 95%CI (1.10, 4.40), P=0.026] and operative time≥3 h [OR=2.07, 95%CI (1.12, 3.85), P=0.021] were independent risk factors for postoperative complications≥gradeⅡ after lung cancer surgery. Conclusion     Surgical approach, extent of resection and operative time are independent influencing factors for postoperative complications≥gradeⅡ after lung cancer surgery.
