ABSTRACT
Objective To explore the influences of serotonin transporter promoter region (5-HTTLPR)polymorphism on hypersensitive C-reactive protein(hs-CRP)in patients with depression. Method 5-HTTLPR polymorphism was detected by polymerase chain reactive-restriction fragment length polymorphism(PCR-RFLP)in 103 patients with depression and 103 healthy controls.The severity of depres-sion was evaluated by Hamilton Depression Scale(HAMD).The hs-CRP level was tested by immunofluores-cence.The influence of different genotypes on hs-CRP and the interaction of genotype and hs-CRP on the pathogenesis of depression were analyzed. Results The frequency of genotype and allele in 5-HTTLPR was no statistical significant(P=0.81,0.121)among the three groups.There were statistically significant differ-ences in hs-CRP concentration(P=0.007)among the three genotypes of the study group,and the concentra-tion of hs-CRP in SS genotype((8.1±2.7)mg/L)was significantly higher than that in LS((4.9±1.8)mg/L) and LL genotype((5.2±1.3)mg/L)(P=0.002,0.001).The retardation factor in patients were significantly differences in different genotypes(F=4.637,P=0.033).SS genotype(9.3±3.1)was significantly higher than LL(6.1±2.7)and LS genotypes(5.8±2.1)in retardation factor(P=0.008,0.007).Logistic regression analy-sis showed that SS genotype was associated with hs-CRP.The interactive effect was positive related to the morbidity of depression.The correlation of interaction between SS genotype and hs-CRP was greater than LL/LS(OR=1.890,95%CI=1.011-3.396). Conclusion SS genotype of 5-HTTLPR has strengthen effect on hs-CRP.The interaction of genotype and hs-CRP affects the onset of depression.The interaction of SS geno-type and hs-CRP is more likely to effect the onset of depression.
ABSTRACT
Objective To study the mediating effect of big five personality between childhood abuse and anxiety of college students, and to provide basis to intervene their mental disorder.Methods Through stratified sampling,2374 college students in Jiangsu were investigated by the personal report of childhood abuse( PRCA),self-rating anxiety scale(SAS) and the revised NEO five-factor Inventory(NEO-FFI-R).A path analysis was applied by analysis of moment structures(AMOS) version 7.0.Results The path analysis showed that childhood abuse was directly related to anxiety of college students(Sβ=0.123, P＜0.01 ＝ ,and was directly related to 4 dimensions of the NEO-FFI-R( exclusion Openness dimension) (Sβ= -0.216 ～ -0.248,0.309; P ＜ 0.01 ＝.3 dimensions of the NEO-FFI-R( exclusion Openness and Extraversion dimensions) were directly related to anxiety of college students ( Sβ = 0.525,-0.045 ～-0.052, P ＜ 0.05 ＝.Agreeableness, conscientiousness and neuroticism of NEO-FFI-R mediate the relationship between childhood abuse and anxiety of college students.The model fit indexes were x2/df = 0.546 ＜ 3.000, P = 0.460 ＞ 0.050, RMSEA = 0.001 ＜ 0.050, GFI = 1.000, AGFI = 0.998, NFI = 1.000, RFI = 0.998, IFI = 1.000,TLI = 1.002, CFI = 1.000.Conclusion Big five personality as mediated variable mediates the relationship between childhood abuse and anxiety of college students.
ABSTRACT
Objective To study the Mediating effect of insecurity between childhood abuse and emotional distress of medical students,and to provide basis to intervene their mental disorder.Methods Through stratified sampling,262 medical students in Jiangsu were investigated by the Personal Report of Childhood Abuse( PRCA),Self-Rating Feeling of Insecurity Scale( SRFIS),Beck Depression Inventory( BDI ),Self-rating Anxiety Scale(SAS)and Suicide Ideation Scale(SIS).A path analysis was applied by Analysis of Moment Structures(AMOS) version 7.0.Results The path analysis showed that childhood abuse was directly related to insecurity of medical students ( β =0.538,P ＜0.01 ),and was directly related to emotional distress ( β =0.435,P ＜ 0.01 ).Insecurity were directly related to emotional distress of medical students ( β =0.342,P ＜ 0.05 ).Insecurity mediated partly the relationship between childhood abuse and emotional distress of medical students.The model fit indexes were X2/df =1.365 ＜ 3.000,P =O.082 ＞ 0.05,RMSEA =0.037 ＜ 0.050,GFI =0.971,AGFI =0.940,NFI =0.943,RFI =0.902,IFI =0.984,TLI =0.972,CFI =0.984.Conclusion Insecurity as mediated variable mediates the relationship between childhood abuse and emotional distress of medical students.
ABSTRACT
Objective To study the socialization character of the examinee in entrance examination of medical postgraduate.Methods 48 examinee in physical fitness test and 496 examinee in entrance examination of medical postgraduate were investigated by applying minnesota multiphasic personality inventory ( MMPI ).Results ①Female postgraduate entrance examinee had higher scores of social responsibility and absence of social anxiety ( H1 ) than male ( 59.1 ± 9.0 vs 56.0 ± 8.5, 59.0 ± 10.1vs 57.3 ± 8.6, P ＜ 0.05 ).Graduates had higher scores of absence of social anxiety( H1 ) (58.3 ±9.4 vs 52.1 ± 11.5, P＜0.05 ), lower scores of alienation from the society(PD4A) and alienation from the society(S1 A) (44.2 ±7.6 vs 51.7 ±9.0, 39.6 ±7.4 vs 45.9 ±9.6,P＜0.05) than junior college graduates.The unmarried persons had higher scores of alienation from the society (PD4A) than the married persons (44.7±7.7 vs 42.9±7.1,P<0.05).②After controlling the effect of gender,marital status and education level, covariance analysis demonstrated that postgraduate entrance examinee had higher scores of S1A (40.0 ±7.5 vs35.2 ±6.8, P＜0.05).Conclusion There are significant differences of socialization character among postgraduate entrance examinee with the difference of genders, marital status and education level.Postgraduate entrance examinee prefers alienation from the society.
ABSTRACT
Objective To study the mediating effect of psychological defense mechanism between personality and depression or anxiety in postgraduate entrance re-examinee. Methods 496 examinee in entrance re-examination of medical postgraduate were investigated by applying Minnesota Multiphasic Personality Inventory(MMsion and anxiety(r=0. 107 ～0. 668, P＜0.05). Psychological defense mechanism was remarkably correlated with depression and anxiety(r= -0. 090 ～ -0.666, P＜0.05;r=0. 131 ～0. 663, P＜0.01). Personality was significantly correlated with psychological defense mechanism (r = - 0. 158 ～ - 0. 586, P ＜ 0.01;r = 0.125 ～ 0.532, Psion, anxiety factor, explicit anxiety, and fear (21.6%, 43.8%, 35.7%, 65.7%). Conclusion Personality is a remarkable predictor of depression and anxiety,and has indirect and direct influence on depression and anxiety through psychological defense mechanism.
