Objective To study the impact of personality and coping style on postpartum depression.Methods 273 cases of postpartum women were estimated by Edinburgh Postnatal Depression Scale ( EPDS),NEO Five-Factor Inventory (NEO-FFI) and Trait Coping Style Questionnaire (TCSQ). With the SPSS11.5,t-test,correlation analysis and regression analysis were carried out for the collected data. Results 23. 1% of postpartum women suffered from depression. There were significant differences in personality traits and coping styles between postpartum depression group and normal group(P＜ 0. 01 ). There was a significant correlation in depression of postpartum and neuroticism, extraversion ( r = - 0. 409 ～ 0. 824 ), agreeableness of personality traits, coping styles.The personality traits was related to coping styles ( r = 0.260, - 0.445, - 0. 234,0. 375 , - 0.431 ). The extraversion, agreeableness of personality traits, negative coping style and positive coping style entered the regression equation of depression and can explain the 32.9% percent variance. Conclusion The extraversion, agreeableness of personality traits, negative coping style and positive coping style are important factors for postpartum depression.

Objective To investigate correlation of right ventricular hypertrophy and vitamin D , atrial fibrillation and NT-proBNP in patients with pulmonary heart disease.Methods 40 cases of pulmonary heart disease were selected, according to whether the right ventricular hypertrophy or not, and divided into hypertrophy group and non hypertrophy group.Echocardiography, serum 25 hydroxy vitamin D, 24 h dynamic electrocardiogram and NT-proBNP level were detected, and the correlation were detected between the right ventricular hypertrophy and influence factors.ResuIts The right ventricular anterior wall ( RVAW) and right ventricular diastolic diameter ( RVDd) in hypertrophy group were significantly greater than those in non hypertrophy group (P<0.05).The serum 25 hydroxy vitamin D levels in hypertrophy group was lower than that in non hypertrophy group (P<0.05), but there was no significant correlation of right ventricular hypertrophy and 25 hydroxy vitamin D levels(r=-0.189,P=0.424).The thickness of right ventricular anterior wall in atrial fibrillation group was greater than that in non atrial fibrillation group (P<0.05), but there was no significant correlation of right ventricular hypertrophy and atrial fibrillation times(r=0.178,P=0.452).Serum NT-proBNP levels in hypertrophy group was higher than that in non hypertrophy group (P<0.05), but there was no significant correlation of right ventricular hypertrophy and serum NT-proBNP levels(r=-0.105, P=0.660).ConcIusion Patients with right ventricular hypertrophy of pulmonary heart disease who has a lower serum 25 hydroxy vitamin D level and a higher NT-proBNP level.Patients with atrial fibrillation has a thicker RVAW.However, there was no correlation of above influence factors.
