Objective:To establish a preliminary diagnostic criteria of pathological internet use for field test in China.Methods:Through searching common "pathological internet use" diagnostic criteria or screen criteria in literature,a diagnostic criteria items pool and a preliminary diagnostic criteria of "pathological internet use" were established .According to the diagnostic criteria,each 2 senior professional psychiatrists in turn interviewed 79 patients and their parents,and then made diagnosis respectively. In addiction,44 high school students were each evaluated by one psychiatrist.The definite diagnosis was made when 2 evaluators make the same diagnosis for one patient.Result:In 123 patients,54 were pathological internet use.For diagnosis,the value of kappa for inter-rater reliability was 0.812( P<0.001).In the 12 criteria items,2 for poor inter-rater reliability and 4 for little contribution to diagnosis were eliminated.In the reserved 6 items,if 4 items(or more)were positive,the diagnostic sensitivity was 78.9% and specificity was 95.3%.Functional impairment criteria were made strictly.In the patients who were made the definite diagnosis,90.7% had duration of illness above 3 months,and 77.7% above 6 months.Conclusion:The preliminary diagnostic criteria of pathological internet use after revised includes 6 symptom criteria,3 functional impairment criteria,duration of illness and exclusive criteria.The criteria proposed is with high consistency on evaluations made by psychiatric raters,and with operational convenience.The criteria,after further revised,may fit the clinical application.

Objective:To assess mental health literacy of urban porpulation and its related factors.Method:Subjects were sampled from 3 cities in the east(Wuxi),central(Changsha)and west(Xi'an)part of China.Subjects were asked to answer a questionnaire which included 5 vignettes of mental disorders and related questions.Results:54.1% of 7309 participants correctly recognized the cases of mania,but only 11.2% correctly recognized the cases of schizophrenia with negative symptoms.The average rate of correct recognition for all 5 vignettes was 41.7%.Participants with higher education level recognized the vignettes more correctly.Ill-character,stress and the pressure from work were reported to be the 3 main reasons of mental disorders.There were strong negative attitudes toward psychiatric patients,especially those with schizophrenia and mania.Conclusion:While the rate of correct recognition of mental disorders is acceptable when compared with similar studies in other parts of the world,negative attitude toward patients with mental disorder is still prevalent in China.

Objective:To explore the relationship between sleep structure changes and state or trait anxiety in patients with insomnia.Methods:Investigations were conducted with the State-trait Anxiety Inventory (STAI) and whole-night ploysomnography (PSG) recorded in 31 patients with insomnia and 20 normal controls.Repeated examinations were conducted in return visits 3～4 months after discharge.Results:Compared to control group,the patients with insomnia had decreased sleep time[(333.71±84.33) min vs.(403.65±19.29) min] and sleep efficiency[(70.41±17.35) % vs.(83.45±4.42) %],and increased sleep latency[(39.48±24.24) min vs.(19.65±8.57) min],REM sleep latency[(106.60±42.89) min vs.(86.80±12.25) min],proportion of S_1 sleep time[(25.36±14.22) % vs.(8.86±1.77) %]and awakening times[(4.45±2.51)vs.(1.75±1.07)].The proportions of S_(3+4) time[(7.38±9.70) % vs.(13.78±4.24) %] and REM sleep time reduced[(14.54±5.61) % vs.(19.18±2.14)%] (Ps<0.05).According to the STAI,scores of both state anxiety[(47.94±8.96) vs.(39.15±4.51)] and trait anxiety[(49.94±8.90) vs.(42.05±7.13)] were significantly higher in insomnia group than in control group (Ps<0.05).State anxiety was positively correlated with sleep latency (r=0.42),REM sleep latency (r=0.25),awakening times (r=0.44) and proportion of S_1 sleep time (r=0.34) (Ps<0.05),and negatively correlated with proportion of REM sleep time (r=-0.41,P<0.01).Trait anxiety was positively correlated with sleep latency (r=0.37,P<0.01) and wakefulness frequency (r=0.29,P<0.05).In return visits,the sleep structure improved,state anxiety score reduced,and trait anxiety had no significant changes.Conclusion:Patients with insomnia have significant sleep structural changes and higher state and trait anxiety.Their sleep structural changes are possilly related to state and trait anxiety.

Objective:To understand whether or not biofeedback therapy(BT)and cue- exposure therapy(CET)could decrease craving and heroin-related cue reactivity in abstinent heroin dependents.Methods:Adopting stratified sampling means,60 abstinent heroin dependents whose craving increased after cue exposed,were allocated to experiment group(n=36)and control group(n=24).The control group dependents received assistance and education.Beside the assistance and education,the experiment group also received 12 times combination therapies of BT and CET.Results:After therapies,the experiment group dependents' craving,EMG and skin conductance(SC)were all decreased compared with control group before cue exposures and after cue exposures[Before cue exposures,the indexes were:craving(3.06±7.26)mm vs.(22.32±20.26)mm;EMG(8.52±4.23)μV vs.(12.06±5.17)μV,SC(2.14±1.43)μS vs.(4.61±2.24)μS.After cue exposures the indexes were:craving(6.97±10.30)mm vs.(33.14±25.40)mm,MEG(8.72±4.31)μV vs.(14.79±5.86)μV,SC(2.15±1.33)μS vs.(4.49±2.59)μS;Ps≤0.01.Conclusion:The combination of biofeedback therapy and cue-exposure therapy could decrease the dependents' craving and cue reactivity sensitivity.

Objective:To investigate the effect of sandplay therapy on repeated dream.Methods:A patient who had been puzzled by repeated dream for years was treated by sandplay therapy.Results:The patient's repeated dream changed greatly,and made it have transformations as follows.(1)Frequency.Dream appeared less and less,even disappeared;(2)Emotion.It was less negative,and the intensity alleviated by degrees;(3)Develop direction.It was more positive;(4)The develop pace was more rapid.Intervention expedited the step and there were marked seedtime;(5)Repeated elements in dream were more positive.Conclusion:Repeated dream will disappear when emotion has been released and the problem has been settled.Sandplay therapy may be effective in the intervention on repeated dream.

Objective:To examine the social support mechanism of pet ownership and pet attachment.Method:A total of 321 pet owners and 418 non pet owners above 40 years in Beijing were measured with questionnaires.Results: (1) Pet ownership showed significant correlations with physical health and life satisfaction.Compared with non pet owners,pet owners had better physical health and life satisfaction (β=0.074;P<0.05,β=0.110;P<0.01).(2)Pet ownership could change the effect of recent life events on the physical health but not on life satisfaction (Z=2.59,P<0.01).(3) Pet attachment showed significant correlations with life satisfaction.The pet owners with more pet attachment had higher life satisfaction.Conclusions:Pet ownership has significant main effect of social support as well as buffering effect of social support.They appear as the significant moderating effects on recent life events and physical health.Pet attachment has significant main effect of social support,and few buffering effects of social support.

Objective:To reveal the actual living conditions and the vulnerability of the life quality of orphans with acquired immune deficiency syndrome (AIDS) in China,and to provide basis for appropriate relative health promotion strategies.Methods:Using gender-age 1∶ 1 matching design,96 pairs of AIDS orphans and children from ordinary families in a county of Henan Province were investigated for their living conditions and subjective quality of life with the Inventory of Subjective Life Quality.Results:(1) Compared with the control group,AIDS orphans had lower life satisfaction (45.16% vs.62.37%,P=0.019),suffered more injustice and stigma (35.48% vs.12.90%,P<0.001),had more needs to work to earn money (55.91% vs.23.66%,P<0.001) and lower probability to receive medical treatments when they were sick (36.36% vs.78.85%,P<0.001).(2) The average total score of subjective life quality in orphan group was significantly lower than that in the control group[(145.9±16.0) vs.(154.9±16.1),P<0.001].Scores of four dimensions including family life,school life,living environment and self-awareness were all significantly lower in orphans than in non-orphans which resulted in the significantly lower awareness stratum scores.(3) The average total score of subjective life quality in male orphan group was significantly lower than that in the male control group[(143.2±16.7) vs.(155.8±17.1),P<0.001].Scores of four dimensions including family life,school life,living environment and self-awareness were all significantly lower in male orphans than in male non-orphans which resulted in the significantly lower awareness stratum scores.Conclusion:AIDS orphans have more problems in lives.Their life quality is significantly affected which mainly appears as the decline of self-awareness and environmental awareness level.Long-term impacts on emotion and mental health deserve special concern.Male orphans are more vulnerable than females.

Objective:To establish animal model on the basis of the autoimmune etiology for a subset of cases of Tourette syndrome.Methods:Blood samples were drawn from patients with TS(by DSM-IV)and were sent for further enzyme-linked immunosorbent assays(ELISA)to a laboratory.Eight serum samples with the highest concentration of anti-neural antibody were selected for TS model group,and 8 serum sampled with the lowest concentration of anti-neural antibody were selected for the control group.Osmotic mini pump filled with undiluted TS or control serum were microinfused into the rat striatum at a rate of 0.5 μl /h for 72 h.Stereotypic movements were recorded at 1 d,7 d,14 d and 21 d after microinfusion.Several categories of stereotypy including bites(teeth touching the cage,wood chips,vacuous chewing or other objects except the body),taffy pulling(raises of the forepaw to the mouth and face),self-gnawing,licking not associated with grooming,grooming,head shaking,paw shaking,rearing and episodic utterances(EU)were recorded.Results:The anti-neural antibody serum concentration used for TS model was(0.29±0.06) U/L,and that used in control group was (0.10±0.04) U/L.After infusion of TS sera,stereotypic behaviors in rats was increased significantly[(37.2±7.1) vs.(106.3±11.7),P=0.000].Significant difference were observed in stereotypies scores of TS rats compared to control rats after microinfusion[(106.3±11.7) vs.(31.2±6.2),P=0.000].Conclusion:Stereotypic behaviors are increased in rats after intrastriatal microinfusion of Tourette Syndrome sera under noninflammatory conditions.

Objective:To evaluate the reliability and validity of the Chinese version of Interpersonal Stress-Coping Inventory for Undergraduates(ISI).Methods:Totally 421 college students of 1～3 grades in two colleges of Anhui province were selected.They were asked to complete the ISI and Simplified Coping Style Questionnaire(SCSQ)at the same time to test the reliability and validity of ISI.Two weeks later,52 of them were retested to test the re-test reliability.Results:Cronbach α of the Chinese version of ISI was 0.79,re-test reliability was 0.87.ISI Scores were correlated with SCSQ scores(r=0.69).Exploratory factor analysis was applied to the data,and three subscales were derived:positive coping,negative coping,and dilution coping.The factor loadinps were 0.41～0.68.The explained variances were 14.82,14.10,and 7.06 respectively.Conclusion:The Chinese version of Interpersonal Stress-Coping Inventory has good psychometric quality and can be used in Chinese undergraduates of interpersonal stress coping research.

Objective:To examine the characteristics of oculomotor inhibition about children with attention deficit hyperactivity disorder(ADHD).Methods:Twenty-one children with ADHD according to the Diagnostic and Statistical Manual of Mental Disorder,4th edition(DSM-IV) and 21 matched controls were administered with fixation,prosaccade and antisaccade tasks.Results:(1) In the fixation task,the children with ADHD demonstrated significantly more intrusive saccade errors than the controls in either condition with distractors or without distractors[no distractors:(12.67±12.28) vs.(6.38±6.95),P=0.040;distractors:(16.91±10.00) vs.(11.29±5.99),P=0.030].(2) In the prosaccade task,there were no significant differences found between groups in saccadic parameters,in either gap condition or overlap condition.(3) In antisaccade task,the direction error rates of the ADHD group in either gap condition or overlap condition,were both higher than that of the control group[gap:(68.14±17.85) % vs.(54.10±20.22) %,P=0.020;overlap:(62.49±17.54) % vs.(49.27±17.21) %,P=0.020].Conclusion: It suggests that there is an abnormality of the oculomotor inhibition,which may be caused by abnormal structure and/or function of fronto-striatal in ADHD children.
