Objective To evaluate the effects of 6-week atypical antipsychotics treatment on serum brain-derived neurotrophic factor (BDNF)level,and the correlation between BDNF level and clinical efficiency in first-episode antipsychotic-na?ve schizophrenia.Methods We recruited 39 hospitalized patients with first-episode antipsychotic-na?ve schizophrenia that met with Diagnostic and Statistical Manual of Mental Disorders—4th Edition (DSM-IV).Both Positive and Negative Syndrome Scale (PANSS)and the level of serum BDNF were measured before and after 6 weeks’treatment with atypical antipsychotics.We also studied 30 healthy controls.Serum BDNF was assayed at baseline.Results Pre-treatment BDNF level was significantly lower in the schizophrenic patients than in the controls [(6.82±2.1 5 )μg/L vs .(1 1.6 ± 3.32 )μg/L,t = 7.239,P < 0.001 ].Although BDNF level increased with treatment (t =2.349,P =0.021)in the schizophrenics,post-treatment BDNF level was still lower than in the normal controls (t =4.634,P <0.001).After 6 weeks’treatment for schizophrenia,the total score of PANSS,the scores of positive and negative symptoms,and the score of general psychopathology scale were all decreased (t =6.1 64,P < 0.001;t = 4.520,P < 0.001;t = 4.132,P < 0.001;t = 5.142,P < 0.001 ).Pre-treatment BDNF levels were directly correlated not only with the rate of decreased PANSS total score (r =0.348, P <0.05),but also with the rate of decreased negative symptoms score (r = 0.35 1,P < 0.05 ).However,pre-treatment BDNF levels were not correlated with improved positive symptoms,general psychopathology (r =0.204, 0.186,P >0.05),or duration of illness (r = - 0.058,P > 0.05 ).Changes in BDNF levels with treatment were correlated with the duration of illness (r =-0.345,P <0.05),but not with psychiatric improvement (r =0.036-0.1 74,P >0.05).Conclusion BDNF level is significantly lower in patients with first-episode antipsychotic-na?ve schizophrenia than in normal controls.It could be improved by using antipsychotics.Higher pre-treatment BDNF level may predict better response to antipsychotics.

Objective To investigate the effects of comprehensive psychological intervention on psychological and biochemical indexes of servicemen in three degree combat readiness. Methods 189 servicemen in three degree combat readiness were randomly divided into the study group and the control group by squad. Beyond the same exercise and education as the control group, the study group received the comprehensive psychological intervention in the course. They were all assessed with Self-rating Depression Scale (SDS) ,self-rating anxiety scale (SAS) ,and simplified coping style questionnaire (SCSQ) at the day entering three degree combat readiness (prereadiness) and the next day after the mission (post-readiness). The serum concentrations of superoxide dismutase ( SOD), malondialdehyde ( MDA), cortisol ( COR), and aldosterone (ALD) were determined to evaluate biochemical indexes at the same time. Results Compared with the control group after the combat readiness, the total scores of SDS( (42.1 ± 9.3 ) vs (49.2 ± 10.3 ) ) and SAS( (43.8 ± 7.2) vs (50.6 ± 10.2), P< 0. 01 ) were lower, the score of the positive coping style ( ( 21.2 ± 6.4) vs ( 18.2 ± 5.4), P < 0. 05 ) was higher in the study group.Meanwhile,the levels of MDA( (2.6 ±0.51 ) μmol/L) ,COR( (252.5 ±52.4) ng/ml) ,and ALD ( (97.5 ±24.4) pg/ml) were lower ( P < 0. 01 ), the activity of SOD ( ( 1551 ± 354 ) U/gHb) was higher ( P < 0. 01 ) after the combat readiness. In the control group post-readiness, the total scores of SDS (49.2 ± 10.3) and SAS (50.6± 10.2) ,the levels of MDA ( (2.9 ±0.35 ) μmol/L) ,COR( (333.8 ±62.6) ng/ml) ,and ALD( ( 123.8 ±29.6)pg/ml ) increased significantly (P<0.01), the score of the positive coping style ( 18.2 ± 5.4) and the activity of SOD ( 1302 ± 352 ) U/gHb decreased significantly ( P < 0. 01 ). The total scores of SDS, SAS were negatively related to the level of SOD ( r= -0. 142, -0. 119, P<0. 0lor 0.05) ,and positively related to COR ( r=0. 156,0. 159, P<0. 01 ) and ALD ( r=0.151,0.156, P<0. 01 ). The score of positive coping style was positively related to the level of SOD ( r=0. 141, P<0. 01 ) ,and negatively related to COR and ALD ( r= -0. 152, -0. 155, P< 0. 01 ). Conclusion Comprehensive psychological intervention could effectively improve the psychological and biochemical indexes,reduce the stress level of servicemen in three degree combat readiness.

Objective To identify the metabolic alterations in the prefrontal lobe in male patients with schizophrenia by proton magnetic resonance spectroscopy (~1H-MRS), and to study the relationship between metabolic alterations and executive function. Methods The study was conducted in 26 male schizophrenics with medicine-free for at least 7 days and 28 normal controls. A multi-voxel ~1H-MRS on the prefrontal lobe was performed in all the subjects within 24 hours of admission. Wisconsin Card Sorting Test (WCST) was used to evaluate executive function. The NAA, Cho and Cr were measured and the ratios of NAA/Cr, Cho/Cr and NAA/(Cho+Cr) were calculated. Results Compared with normal controls, the patients demonstrated significantly lower NAA/Cr ratio (t=2.93, P<0.01) in the left prefrontal lobe and poorer performance in WCST (P<0.05). The NAA/Cr ratio in the left prefrontal lobe was positively associated with the responses errors and the perseverative errors of WCST(r=0.45, P<0.05; r=0.47, P<0.05)and negatively associated with the categories completed and conceptual level responses(r=-0.54, P<0.01; r=-0.56, P<0.01). Conclusions Abnormalities in neuronal function and/or integrity are present in the left prefrontal lobe of male schizophrenics. The neuron damage in the left prefrontal lobe of male schizophrenic may be the primary cause of cognition dysfunction.
