Objective To explore the influence of cognitive-behavioral therapy on the quality of life of elderly depression patients with chronic pain.Methods 60 patients were divided into the cognitive-behavioral therapy(CBT) group and non-cognitive-behavioral therapy(N-CBT) group,30 cases in each group.The patients in CBT group were treated with cognitive-behavioral therapy combined with mirtazapine,and the patients in N-CBT group were treated with mirtazapine only.Before treating and after the 4th week and 12th week,depression,anxiety and chronic pain were assessed respectively with Hamilton Depression Scale ( HAMD),Hamilton Anxiety Scale (HAMA),and Visual Analogue Scales (VAS),the quality of life was assessed with the WHO Quality of Life ( WHO.QOL-100).No significant different scores of HAMD,HAMA,VAS and WHOQOL-100 existed between two groups before treatment.Results Depression,anxiety and chronic pain were significantly related to the life quality of elderly depression patients with chronic pain ( r =-0.506 ～ -0.676,P ＜ 0.01 ).At the end of the 12th treating week,the scores of HAMD(36.82 ±7.93),HAMA(8.26 ±3.13),VAS(4.35 ±0.52) and WHOQOL100 ( respectively ( 65.71 ± 17.29 ),( 92.36 ± 13.55 ),( 77.91 ± 12.26 ),( 78.33 ± 12.81 ),( 81.79 ± 12.43 ),( 18.95 ± 11.91 ),( 19.98 ± 11.56 ) ) were significantly different from those before treatment in CBT group,and the change of each indicator score was significantly greater in CBT group than those in N-CBT group ( t =3.020 ～9.761,P＜ 0.01 ).Conclusion Cognitive-behavioral therapy can effectively improve the life quality of the elderly depression patients with chronic pain.

Objective To explore the tridimensional personality characteristics of heroin addicts and the relationship with their mental state.Methods The personality character of 113 general adult and 100 heroin addicts were tested with tridimensional personality questionnaire(TPQ),and the mental state for the heroin addicts were tested with symptom of check- list(SCL-90) and to contrast the consequence with the norm of Chinese.Results NS and HA scores in heroin addicts( ( 18.07 ±4.13),( 16.06 ± 5.13) ) were higher than those in normal control group( ( 16.22 ± 4.88),( 13.98 ± 6.11 ) ) (P ＜ 0.05 ),and RD scores ( 17.22 t 3.18 ) was lower than that of the control group (18.27 ± 3.73 ),the difference was statistically significant (P ＜ 0.05 ).The total score of SCL-90 and 9 factors score of heroin addicts were higher than the national norm,the difference was statistically significant (P ＜ 0.01 ),in which somatization,obsession,depression and psychosis were more prominent ; HA scores in heroin addicts were positively associated with the factors including obsession,interpersonal relation sensitivity,depression and positive project number.The Pearson correlation coefficient were respectively 0.226,0.243,0.201,0.215,the difference was statistically significant (P＜ 0.05).Conclusion The personality characteristics of heroin addicts is special and is correlated with their mental health state.

Objective To compare the clinical feature and cognitive function between patients with obsessive-compulsive disorder of different onset age and explore possible subtype.Methods 140 Patients with obsessive-compulsive disorder (OCD) were enrolled in test.All finished a series of tests including clinical feature,Trail-making test (TMT),Tower of Hanoi (TH) and Word fluency test (WFT).Patients were divided into two groups by onset age of 18.Results Compared with patients of onset age after18,patients of onset before18 were more with episode duration and more suicide attitude( x2 =4.214,x2 =11.542,P＜ 0.05 ).In TMT patients of onset before 18 had shorter time and little errors( (81.696 ±50.172)vs( 109.114 ±48.070),(1.169 ±2.983) vs ( 1.405 ± 2.020),P ＜ 0.05 ).Conclusion Obsessive-compulsive disorder with different onset age may be different type.

Objectives To explore the brain white matter integrity among the patients with buprenorphine tables,scopolamine and promethazine solution(BSP) dependence after abstinence.Methods BSP-dependent patients( n=16)and age/eduction-matched healthy control subjects ( n=18) were assessed by diffusion tensor imaging (DTI) after 3 days,1 month and 2 months of abstinence.White matter (WM) integrity was measured with DTI as fractional anisotropy ( FA),an index of intravoxel orientational coherence of white matter fibers.Results Compared with health controls,FA values were significantly lower in frontal,parietal,temporal and corpus callosum in the BSP addicts after 3-day withdrawal (P＜0.001,uncorrected).Increased FA values in left superior frontal cortex,right medial frontal gyms and fight inferior parietal gyrus were found in BSP users after 2 months of abstinence (P ＜0.001,uncorrected).However,no significant difference was found between these BSP addicts after 1-month abstince.Compared with health controls,BSP dependent subjects still exhibited significantly lower FA in the corpus callosum,frontal,parietal and temporal WM after 2-month withdrawal (P ＜ 0.001,uncorrected ).Conclusion The abnormalities showed less recovery in BSP dependent individuals with abstinence in white matter that suggests that rehabilitation time should be further prolonged for BSP addicts and emphasis cognitive-behavioral therapy to assist BSP abusers rebuild social functions.

Objective To investigate the effects of a highly selective dopamine D4 receptor (ABT-724)on behaviors in Spontaneously hypertensive rats (SHR),a rat model of attention-deficit hyperactivity disorder (ADHD).Methods After intervention of methylphenidate(5mg/kg) and three different doses of ABT-724(0.04mg/kg,0.16mg/kg,0.64mg/kg),behaviors of SHR were verified by open-field test,Morris water maze and Làt maze.Results Number of square crossing after intervention of methylphenidate and ABT-724 in SHR( 70.67 ± 8.59,76.50 ± 10.75,79.17 ± 10.44,65.67 ± 20.62) was less than the saline control group( 130.33 ± 1 1.40) (P＜0.05).During Morris water maze,SHRs(52.50 ± 4.04,52.17 ± 2.99,61 ± 8.15,53.83 ± 9.87 ) after intervention of both had a better spatial memory ability than control group(38.83 ±7.17) (P＜0.05).In Làt maze,number of rearing after intervention of both in SHRs(57.17 ± 5.67,60.83 ± 8.28,55.17 ± 9.45,65.33 ± 9.50 ) was less than saline control group(78.00 ± 13.84) (P＜0.05).Conclusion ABT-724 could improve behaviors of spontaneous locomotor activity,cognitive ability,non-selective attention in SHR.

Objective To investigate the tracking neurofibra pathway from the hippocamlpal neurons to septal nucleus,and to explore the effects and mechanisms of ghrelin on the learning and memory in septal nucleus lesion rats.Methods Retrogradely tracing method was used to observe Fluorogold (FG) reaching sites in hippocampus.The septal nucleus was destructed by direct current using stereotactic technique.Step-down test and morris water maze were used to test the effects of learning and memory ability by means of microinjecting ghrelin into hippocampal CA1 area in rats.Results After injection of FG into septal nucleus,retrogradely labeled neurons and neurofibra were found in the hippocampal neurons with FG.Ghrelin injection of hippocampal CAI area could promoter learning and memory ability in rats.It showed that the escaped latent period was significantly lengthened ( (3.2 ± 0.9) s vs (6.9 ± 1.1 ) s,P ＜ 0.05) and the wrong numbers in 5 min were obviously decreased in escape response test; and the latency of looking for the plat was significantly shorter in morris water maze test ( 1.8 ±0.4vs 0.8 ± 0.1,P ＜ 0.05 ).However the effects above-mentioned on learning and memory was significantly weak after septal nucleus lesioning.It showed that the escaped latent period was markedly shortened ( ( 19.5 ±3.2)s vs ( 10.5 ± 2.1 ) s,P ＜ 0.05 ) and the wrong numbers in 5 min were obviously increased ( ( 3.9 ± 0.8 ) s vs ( 1.8 ±0.5 ) s,P＜0.05 ) in escape response test.The latency of looking for the plat was significantly lengthened in morris water maze (P＜0.05).Conclusion Ghrelin could elevate the learning and memory ability in hippocampus,and the effects may be related to the septal-hippecampus pathway.

Objectives To assess if visual analogue scale(VAS) or Likert scale was relatively more suitable when measuring self-reported clinical outcomes for apoplexy spastic-paralysis patients.Methods Nineteen questions were made from the serf-evaluating instrument based on patient reported outcomes for apoplexy spasticparalysis patients developed previously in cross-sectional study.104 patients answered the questions by both continuous and discrete visual analogue scale(VAS),while other 110 patients by both five-point Likert scales and Likert-typo scales.Cronbach'sαfor internal consistency reliability,spearman for correlation,and exploratory factor analysis for construct validity were applied.Results Except for emotional domain,the α coefficients of physical domain,social domain and overall score with continuous and discrete VAS are higher than that with five-point Likert scales and Likert-type scales.Internal consistency reliability was stronger for VAS.lntraclass correlation coefficients were above 0.4 mostly for each item with its domain,and VAS may produce the higher correlation.For VAS,there were three factors in the exploratory factor analysis,which confirmed the domain hypotheses of physical,mental and social functions,but for the Likert scales,the result was undesiable.Conclusion The more accurate for the response options,the better for the performance.When the patient can complete the measurement without the help of others,VAS seems better suited.

Objective To investigate the correlation of father involvement with early social adaptation behaviors.Methods With social adaptation scale for infant-junior middle school' s student and a self-made questionnaire,1246 normal children,age from 16 to 72 months,were investigated.Regression analysis was performed to get the correlation of social adaptation with time and activities of father involved.Results After controlling for mother-,child- and family-related factors,the regression analysis showed that standard score of social adaptation was positively rehted with the time of father involved ( β =0.05,P=0.03 ),the time father invloved explain 12％of the variation of social adaptation.The father-child activities were related with social adaptation behavior,playing was related with work skills (β =0.09,P＜0.01 ) and socialization ( β =0.06,P＜0.05),story listening related with communication ( β =0.07,P ＜ 0.05) and self-management ( β =0.06,P ＜ 0.05 ),other activities related with self-dependence ( β =0.07,P＜0.05) and work skills ( β =0.06,P＜0.05).Conclusion The time and activities of father involved are related with children' s social adaptation.The effect of father involvement on early social adaptation is positive.
