Objective:To study the relationship between sleep quality and psychosocial factors in prison police officers.Methods:Pittsburgh Sleep Quality Index(PSQI),Eysenck Personality Questionnaire(EPQ),Life Event Scale(LES) and Coping Style Questionnaire(CSQ) were used to evaluate the sleep status and psychosocial factors of 2093 prison police officers of Guangdong Province Prison Administration Bureau.Results:Their average score of PSQI was 7.10?3.68.40.71% of them had sleep problems.The scores of PSQI were correlated positively with the scores of N,negative life events,self-blame and rationalization,and negatively with working out a solution.Conclusion:The sleep quality problem of the prison police officers is serious.Their sleep disorder is obviously related to their mood stability,enduring negativity life events and coping style.

Objective: To study the state of prison police officers'sleep quality and anxiety, depression and their relationship. Methods: Pittsburgh Sleep Quality Index (PSQI) , Self Rating Anxiety Scale (SAS) and Self Rating Depression Scale (SDS) were evaluated the sleep, anxiety and depression status of 2093 prison police officers of Guangdong Province Prison Administration Bureau. Results: The average score of PSQI was 7. 10 ?3.68, 40.71% had sleep problem. The average score of SAS was 41. 64 ?7. 66, 11. 94% officers had anxiety problem. The average score of SDS was 45. 11?8. 01, and 26. 99% had depression problem. The score of PSQI among policemen was higher than that of policewomen officers. The anxiety problem and the SAS? SDS score of the age over 35 years old persons was higher than that of the age below 35 (7. 2 ?3.6/6.7 ?3.9, t =2. 1, P

Objective To analyze the correlation of cerebral perfusion characteristics and cognitive function on patients with unipolar and bipolar depression. Methods The r-CBF imaging was detected by SPECT forall subjects. Evaluated cognitive function of subjects using WAIS-CR and WMA, and analysed data using SPSS.Results Data showed that some regions in the brain, e.g. temporal lobe, frontal lobe, hippocampus, and basal ganglia, had significant alterations of r-CBF in depressed patients as compared with healthy controls (P ＜ 0. 05 ).Compared with UPD, BPD showed increased perfusion in basal ganglia ( 0,22.73%; 4.54%, 36. 36% ) (P ＜0.05 ). Furthermore there was no significant different incognitive deficits between UPD and BPD(P ＞ 0. 05 ) , and correlations between cognitive impairment and hypoperfusion of rCBF (P ＜ 0. 05 ). Conclusion There be exist difference in r-CBF between UPD and BPD. The perfusion of r-CBF in BPD is significantly increased than that in UPD,and it suggest that hyperperfusion in basal ganglia may be the biological basis when bipolar depression turning to manic.

Objective To explore the prevalence of metabolic syndrome( MetS) and its components in patients with bipolar disorder and their lifestyle. Methods Collected 148 cases of bipolar disorder in patients with body mass index (BMI),blood glucose,blood pressure,triglyceride(TG),high-density lipoprotein( HDL-C) etc, and self-compiled scale was used to assess their lifestyle. All patients were followed 6 months. The patients werecompared with 65 normal controls. Results The patients group in the baseline period,treatment after 1 months,3 months and 6 months,the incidence of MetS was as followed:11.5% ,15.5% ,18.2% ,20.9%. The patients at all stages,the incidence of MetS,BMI≥25kg/m2 ,high TG levels,low HDL-C levels and hypertension were significantly higher than the control (P<0.01). After 6 months of treatment the incidence of MetS,hypertriglyceridemia were higher than baseline (P < 0.05). The patients group' s work intensity, frequency of exercise, eat more than 3 times per day compared with the control group were significantly different (P<0.01, P<0.05). Conclusion The incidence of MetS and hyperuricemia in patients with bipolar disorder after treatment is higher than the control group; as a continuation of the treatment,the incidence of metabolic abnormalities increased gradually. Unhealthy lifestyle, lack of exercise,unreasonable diet maybe increase the risk of metabolic disorders.

Objective To investigate the characteristic of regional cerebral blood flow (r-CBF) in patients with major depression disorder (MDD) and bipolar depressed (BPD). Methods The r-CBF imaging was detected by using sin?gle emission computed tomography (SPECT) in 22 treatment naive patients with MDD, 22 treatment naive patients with BPD and 15 healthy controls. The r-CBF was compared between patients and controls. Results Compared to controls, the r-CBF in the bilateral temporal lobe, parietal lobe and basal ganglia significantly decreased in MDD and BPD pa?tients (P<0.001). The r-CBF in the basal ganglia was significantly lower in MDD patients than in BPD patients. Conclu?sion The r-CBF is abnormal in MDD and BPD at the resting state. The r-CBF in the basal ganglia is the main differ?ence between MDD and BPD. The difference might be regarded as a biomarker in distinguishing BPD patients from MDD patients.

Psychiatric symptoms are one of the most common symptoms in patients with anti-N-methyl-D-aspartate (NMDA) receptor encephalitis,which is not specific compared with the symptoms of schizophrenia.Young female patients without previous history of mental disorders have sudden onset of psychiatric symptoms,conscious disturbances or suspicious conscious disturbances,especially in the presence of catatonic,requiring electroencephalogram (EEG) and head magnetic resonance imaging for the identification of anti-NMDA receptor encephalitis.Abnormal NMDA receptor antibody in cerebrospinal fluid is the basis of diagnosis.
