ABSTRACT
Objective To investigate the difference of temporary memory system and brain biochemical metabolites between patients with depressive obsessive-compulsive disorder and simple obsessivecompulsive disorder.Methods From June 2017 to June 2018,31 patients with simple obsessive-compulsive disorder,33 patients with depressive obsessive-compulsive disorder and 25 healthy volunteers were selected as subjects.The temporary memory ability of the three groups was tested by n-back,Stoop color association test and digital breadth test.Three brain sublimation metabolites,N-acetylaspartate acid (NAA),choline complex (Cho) and creatine (Cr),were detected by proton magnetic resonance pop (1 H-MRS) in bilateral prefrontal white matter,anterior cingulate cortex and anterior cingulate cortex.The ratio of NAA/Cr and Cho/Cr was calculated with Cr as reference material.Results The scores of Yale-brown obsessivecompulsive severity scale (Y-BOCS) and Hamilton depression rating scale 24 (HAMD24) in the patients with simple obsessive-compulsive disorder and depression obsessive-compulsive disorder group were significantly higher than those in the healthy control group,and the scores of HAMD24 in the patients with depression obsessive-compulsive disorder group were significantly higher than those in the patients with simple obsessive-compulsive disorder group,with statistically significant difference (P ＜ 0.05).The number of correct n-back in the simple obsessive-compulsive group and the depressive obsessive-compulsive group was significantly lower than that in the healthy control group (P ＜0.05).The digital span test (DST) scores of the patients in the simple obsessive-compulsive disorder group and the depressive obsessive-compulsive disorder group were (14.37 ± 2.96) and (12.39 ± 2.14),which were significantly lower than those in the healthy control group (17.46 ± 3.28) (P ＜ 0.05).There was no significant difference in NAA/Cr and Cho/Cr between the three groups (P ＞ 0.05).Compared with the healthy control group,the NAA/Cr value of bilateral prefrontal white matter in the simple obsessive-compulsive group and the depression obsessivecompulsive group was significantly lower,and the difference was statistically significant (P ＜ 0.05).Conclusions Both patients with simple obsessive-compulsive disorder and depressive obsessive-compulsive disorder had speech memory impairment and bilateral prefrontal white matter nerve function decline,while depressive obsessive-compulsive disorder patients also had central executive memory impairment.

Objective@#To investigate the difference of temporary memory system and brain biochemical metabolites between patients with depressive obsessive-compulsive disorder and simple obsessive-compulsive disorder.@*Methods@#From June 2017 to June 2018, 31 patients with simple obsessive-compulsive disorder, 33 patients with depressive obsessive-compulsive disorder and 25 healthy volunteers were selected as subjects. The temporary memory ability of the three groups was tested by n-back, Stoop color association test and digital breadth test. Three brain sublimation metabolites, N-acetylaspartate acid (NAA), choline complex (Cho) and creatine (Cr), were detected by proton magnetic resonance pop (1H-MRS) in bilateral prefrontal white matter, anterior cingulate cortex and anterior cingulate cortex. The ratio of NAA/Cr and Cho/Cr was calculated with Cr as reference material.@*Results@#The scores of Yale-brown obsessive-compulsive severity scale (Y-BOCS) and Hamilton depression rating scale 24 (HAMD24) in the patients with simple obsessive-compulsive disorder and depression obsessive-compulsive disorder group were significantly higher than those in the healthy control group, and the scores of HAMD24 in the patients with depression obsessive-compulsive disorder group were significantly higher than those in the patients with simple obsessive-compulsive disorder group, with statistically significant difference (P<0.05). The number of correct n-back in the simple obsessive-compulsive group and the depressive obsessive-compulsive group was significantly lower than that in the healthy control group (P<0.05). The digital span test (DST) scores of the patients in the simple obsessive-compulsive disorder group and the depressive obsessive-compulsive disorder group were (14.37±2.96) and (12.39±2.14), which were significantly lower than those in the healthy control group (17.46±3.28) (P<0.05). There was no significant difference in NAA/Cr and Cho/Cr between the three groups (P>0.05). Compared with the healthy control group, the NAA/Cr value of bilateral prefrontal white matter in the simple obsessive-compulsive group and the depression obsessive-compulsive group was significantly lower, and the difference was statistically significant (P<0.05).@*Conclusions@#Both patients with simple obsessive-compulsive disorder and depressive obsessive-compulsive disorder had speech memory impairment and bilateral prefrontal white matter nerve function decline, while depressive obsessive-compulsive disorder patients also had central executive memory impairment.
ABSTRACT
Objective To examine the effects of participating in Balint group ( PBG) for reducing occupational burnout among primary care physicians (PCPs). Methods In this randomized controlled trial, 240 PCPs were randomly assigned to PBG (n=70) and control group (n=240) in propotion of 1 ∶ 2. Sub-jects of PBG received Balint group intervention for one year,while control group received natural observation. Maslach Burnout Inventory ( MBI) was used to assess the severity of occupational burnout. Results At baseline all three subscales of MBI had no significant difference between PBG and cotrol group(P>0. 05). After the intervention,PBG had statistically lower subscale scores in emotional exhaustion ((20. 1±8. 3) vs (22. 6±8. 7),t=1. 993,P=0. 048) and depersonalization (( 6. 8± 4. 9) vs ( 10. 8 ± 5. 2),t=5. 355,P<0. 001) than the control group, while had statistically higher score in personal accomplishment subscale ((38. 3±7. 5) vs (34. 6±7. 7),t=3. 311,P=0. 001) than the control group. Conclusions PBG is effective in reducing occupational burnout among PCPs.
