RESUMO
Objective To determine the potential correlation of 5-HTT gene polymorphisms (5-HTTLPR and STin2) with clinical manifestations in depression.Methods A total of 401 depressed patients,all of Chinese Han region,were collected and genotyped by polymerase chain reactions (PCR).All patients were evaluated using a 17-item Hamilton depression rating scale (HAMD-17) and Hamilton anxiety rating scale (HAMA),and then associated analysis was applied.Results (1) The age of onset in patients with L/S genotype of 5-HTLPR polymorphism were much younger than that of patients with L/L and S/S genotype (F=3.281,P=0.039).Besides,there was also a significant difference of HAMA1 (anxious mood) scores among patients with different genotypes for 5-HTTLPR polymorphism,where the scores of those with L/S genotype were the highest (2.34±0.80,P=0.010).(2) The scores of HAMD10 (mental anxiety),HAMA1 (anxious mood),HAMA3 (fear) and mental anxiety factor were higher in patients with 12/10 genotype than patients with 12/12 and 10/10 genotype for STin2 polymorphism (2.40±0.83,2.38±0.90,1.42± 1.04,14.60±4.26 respectively;P value:0.014,0.044,0.03 and 0.006 respectively).The scores of HAMD10(mental anxiety) and mental anxiety factor were (2.11±0.77),(12.96±3.78) in the 12/12 genotype patients,and significantly lower than that in the 12/10 genotype patients (adjustedPvalue:0.018,0.006).Conclusions A positive association of the 5-HTT polymorphisms with anxious symptoms in depressed patients is revealed.These findings might provide some evidences for the clinical phenotype and optimization of depression treatment.
RESUMO
Objective: To investigate the stress and coping strategy of rescue surgical staff early after earth-quake. Methods: The self reporting questionnaire (SRQ-20) and coping styles questionnaire (CSQ) were distribu-ted to 37 surgical staff and 44 psychiatric staff (the control group) in Chengdu City 2 weeks after Wenchuan earth-quake. The results were analyzed by t test, correlation analysis and logistic regression analysis. Results: The grades of rescue surgical staff in SRQ-20 and negative coping styles factor was higher than that of the psychiatric staff [(9.3±4.7)vs.(3.2±3.9), (29.8±6.2) vs.(26.1±7.1); Ps<0.05] . The SRQ-20 score in rescue surgical staffs was positively correlated with negative coping styles factor (r=0.50, P=0.002) and age (R~2=0.168, P=0.012) . Conclusion: Surgical staff, especially the elder, have more intensive acute stress reaction. It is essential to publicize psychologic knowledge and improve mental health of surgical staff.
