Objective To investigate the factors of influencing plasma glucose level in STZ induced mice with chronic stress. Method We selected forty STZ mice and twenty normal Kun-ming(KM) mice, matched them with plasma glucose.Then the mice were divided into four groups:group A(STZ induced mice plus stress),group B(STZ induced mice),group C(stressing normal mice) and group D(normal mice).Stress factors were restraint, rotation and crowding. Their plasma glucose levels were determined every two weeks during the experiment. The contents of plasma insulin ,?-endorphin(?-EP) and Neuropeptide Y(NPY) in hypothalamus were measured after 6 weeks.Results After the chronic stress, in STZ mice(group A),the levels of plasma glucose and NPY were elevated significantly, the level of plasma insulin were gradually elevaled according to groups A,B,C,D,in sequences,there was obviously differences among the four groups significantly, ?-EP level increased according groups D,C,B and A slightly. Correlation analyses showed that there was negative correlation between the levels of plasma insulin and glucose(r=-0 4555,p

Objective To explore the relevance between writing characteristic and therapeutic effect in schizophrenia and to discuss the influence of aggressive behavior on writing characteristic. Methods Re-coding the casual and fixed writing in admission, one week, two weeks, four weeks, eight weeks after treatment and rating Positive and Negative Syndrome Scale (PANSS) and Modified Overt Aggression Scale (MOAS). Choosing two characteristics, “relationship between font and grid lines” and “having big strokes or not”, and comparing before and after treatment. Results Eight weeks after treatment, the score of PANSS decreased. The condition of patients and the writing characteristic improved as well. The differ-ences of writing characteristics were statistically significant in patients with aggressive behavior before and after treatment (P<0.05). Conclusion The writing characteristic has relation with therapeutic effects and improved with therapeutic effects in aggressive patients.

BACKGROUND: At present, the scale for evaluating cervical vertigo symptoms and functions applied in clinic can evaluate the overall curative effect in patients with cervical spondylosis of vertebral artery type (CSA).However, this scale lacks the content of functional status and emotional function for evaluating daily life function.OBJECTIVE: To develop a functional scale for cervical spondylosis of vertebral artery type (FS-CSA) including functional status and emotional function based on the vertigo disorder scale made abroad.DESIGN: Cross-sectional survey, interview evaluation after pretest, internal consistency, retest consistency and construct validity were measured by the method of Chronbach's c, Pearson correlation coefficients and factor analysis, respectively.SETTING: Clinical Epidemiology/DME Center, Guangzhou University of Traditional Chinese Medicine.PARTICIPANTS: Totally 111 consecutive patients with CSA, 30 men and 81 women aged 31 to 72 years, in the Clinic for Cervical Spondylosis of Guangdong Provincial Hospital of Traditional Chinese Medicine were recruited from May 2001 to March 2002. Altogether 36 patients had risk factors of vertebral-base artery atherosclerosis. There were 14 cases of mild vertigo, 61 cases of moderate vertigo, and 36 cases of severe vertigo. Informed consent was obtained from the participants.METHODS: FS-CSA was made according to clinical actual condition Functional status (going for a walk during the day by yourself, walking around the house in the dark, doing strenuous housework, social activity,traveling for business or recreation, getting into or out of bed, reading books or newspaper; each item was divided into three categories "No,anxious, worried about your illness, and feeling frustrated; each item consisted of three categories "No, Sometimes, and Yes"). Patients with CSA were evaluated by means of interview and 14 of them were retested. Internal consistency, construct validity and correlation coefficients of the scale were measured with SPSS 10.0 software.tional status dimensionality, emotional functional dimensionality as well as internal consistency of the total scale in FS-CAS: Chronbach's α value was 0.875 9, 0.645 3 and 0.859 5, respectively; retest consistency value was extracted common factor was consistent with the two dimensionalities.tool quantifies the life quality of the patients with CSA and can make a uate curative effects of drugs or screen the best treatment scheme; therefore, it has clinical application value.

Objective T o understand the assessm ent on the criminal responsibility of drug-induced m ental disorders and judicial experts’ opinions. Methods T he judicial experts from institutes of forensic psychi-atry in Shanghai were selected. T hey were asked to finish a self-m ade questionnaire of assessm ent on the criminal responsibility of drug-induced m ental disorders by letters and visits. Results Most of experts knewthe special regulation,“not suitable for evaluation” towards the criminal responsibility of drug-in-duced m ental disorders of the guideline prom ulgated by Ministry of Justice. B efore and after the guide-line was issued, no expert m ade a no-responsibility opinion in such cases. After the guideline was issued, som e experts m ade a full-responsibility or lim ited-responsibility opinion in such cases. T here was a little disagreem ent am ong the experts in the case that the crime was unrelated with m ental sym ptom s or the criminals used drugs even though he knewit could induced insanity. B ut there were still m any obvious disagreem ents am ong experts in the case that crime was related to such sym ptom s and person was no ability to debate. Most experts agreed to settle the disagreem ents with im proved legislative perfection. Conclusion Most experts are not strictly com plying with the assessm ent guidelines during their practice, and there is still an obvious disagreem ent towards the criminal responsibility of drug-induced m ental disorders.

Objective To explore the m ain perform ance of personality change in people w ith m ild psy-chiatric im pairm ents w hich due to the brain traum a caused by traffic accidents and its value in assess-m ent of psychiatric im pairm ent. Methods The condition of personality change of patients w ith traum atic brain injury caused by traffic accident w as evaluated by the Scale of Personality Change Post-traum atic Brain Injury (SPCPTBI). Furtherm ore, the correlation betw een the personality change and the degrees of traum atic brain injury and psychiatric im pairm ent w ere explored. Results In 271 sam ples, 239 (88.2% ) w ith personality changes. A m ong these 239 sam ples, 178 (65.7% ), 46 (17.0% ), 15 (5.5% ) w ith m ild, m oderate and severe personality changes, respectively. The ratio based on the extent of personality changes to the degree of brain traum a w as not significant (P>0.05), but the total score difference betw een the groups w as significant (P<0.05). There w as no statistical significance betw een the m edium and high severity brain traum a groups. The higher degree of personality changes, the higher rank of m ental disabilities. The total score difference of the scale of personality change am ong the different m ild psychiatric im pair-m ent group w as significant (P<0.05). The difference betw een other psychiatric im pairm ent levels had statistical significance (P<0.05) except level 7 and 8. Conclusion The occurrence of personality change due to traum atic brain injury caused by traffic accident w as high. Correlations exist betw een the personality change and the degree of psychiatric im pairm ent. Personality change due to brain traum a caused by traffic accident can be assessed effectively by m eans of SPCPTBI, and the correlation betw een the total score and the extent of traum atic brain injury can be found.

OBJECTIVE: To explore the composition characteristics of traditional Chinese medicine (TCM) syndromes in patients with acute ischemic stroke of yin or yang syndrome by investigating the characteristics of TCM syndromes at different periods after onset. METHODS: One thousand two hundred and forty-six patients with acute ischemic stroke were admitted in twenty hospitals. According to the "diagnostic criteria of syndrome differentiation of stroke", the characteristics of syndromes in the patients were investigated at the periods of 1-3 days, 4-10 days and 11-30 days after they had ischemic stroke. General distribution of six basic syndromes was compared between the patients with yin syndrome and the patients with yang syndrome at the three periods. The six basic syndromes were wind syndrome, pathogenic fire syndrome, phlegm syndrome, blood stasis syndrome, qi deficiency syndrome, and syndrome of yin deficiency and yang hyperactivity. RESULTS: The percentages of wind, pathogenic fire, and phlegm syndromes in the patients were decreased at the period of 11-30 days as compared with the period of 1-3 days (87.1% vs 79.3%, 52.1% vs 38.7% and 67.1% vs 57.4% respectively, P<0.01). However, the percentages of the syndromes of blood stasis, qi deficiency, and yin deficiency and yang hyperactivity were similar at the three periods (P>0.05). There were no differences in the distribution of yin and yang syndromes among the three periods (P>0.05). The percentages of syndromes of wind, pathogenic fire, phlegm, and yin deficiency and yang hyperactivity were higher (P<0.01), and the percentages of syndromes of blood stasis and qi deficiency were lower (P<0.05, P<0.01) in patients with yang syndrome than in patients with yin syndrome. The complex of three syndromes was the most frequent composition pattern in the patients at the three periods. The percentages of complex syndromes of four or five syndromes were higher, and the percentages of single-syndromes and complex syndromes of two syndromes were lower in patients with yang syndrome than in patients with yin syndrome (P<0.05, P<0.01). The most frequent complex syndromes in patients with yin syndrome were complex syndrome of wind, phlegm, blood stasis and qi deficiency, and complex syndrome of wind, phlegm and qi deficiency; while the most frequent complex syndromes in patients with yang syndrome were complex syndrome of wind, pathogenic fire, phlegm and qi deficiency, and complex syndrome of wind, pathogenic fire and phlegm. CONCLUSION: The main discrimination between the yin and yang syndromes is that the yang syndrome is characterized by pathogenic fire. The syndromes of phlegm, qi deficiency, and blood stasis are not associated with the diagnosis of yin or yang syndrome.

To investigate the prevalence of mental health problems in male violent offenders of Hunan and Sichuan Provinces; and to compare the types and severity of problems between the violent and nonviolent offenders.Methods:Ninety-one violent juvenile offenders and 64 nonviolent juvenile offenders in the juvenile detention centers of Hunan,and 81 violent juvenile offenders in the juvenile detention centers of Sichuan; 39 high school students from a middle school of Hunan Province and 49 from a middle school of Sichuan Province were investigated using the Investigation Screening Inventory for Child Mental Disorder and the Kiddy Schedule for Affective Diseases and Schizophrenia (K-SADS-PL),and classified according to the Diagnostic and Statistical Manual of Mental Disorders.Results:In the Hunan violent group,86.6％ met the criterion of conduct disorder (CD),17.6％ of substance abuse,9.9％ of substance dependence,while in the Hunan nonviolent group,75.0％ met the criterion of CD,and 11.7％ of substance abuse; these were all significantly higher than those of the control group (P＜0.05).In the Sichuan violent group,17.3％ met the criterion of attention deficit/hyperactivity disorder (ADHD),18.5％ of oppositional defiant disorder (ODD),69.1％of CD,and 22.2％ of substance abuse; these were all significantly higher than those of the Sichuan control group.Moreover,63.7％ of Hunan-violent,55.6％ of Sichuan-violent,and 45.0％ of Hunannonviolent offenders had a previous offence records.Conclusion:Mental and behavioral disorders among delinquent youth is becoming a serious problem,and there is an urgent need to develop and implement effective assessment and treatment approaches for juvenile offenders with the aim of reducing offence and recidivism in this population.

Objective To observe the cardiac function in acute brain injury patients(ABI)and the relationship between ABI and plasma neuropeptideY(NPY),and to inspect the mechanism and find the evidences for preventing cardiac impairment caused by ABI. Methods 89 patients with acute brain injury within 24 hours after the injury were divided into severe group(n =47)and mild group(n = 42)according to Glasgow Coma Scale(GCS),and 35 normal healthy adults were selected as control group.In 24 hours and 72 hours after the brain injury,all patients were examined with echocardiography to observe cardiac structure,Doppler blood flow velocity and cardiac function,and in the same time the plasma NPY were determined by radioimmunoassay.Then the results were compared with controls. Results The parameters of cardiac function such as EF、 SV.AV、CO、CI had statistical change in 24 hours and 72hours after the brain injury between severe ABI group and mild ABI group,and it also had statistical change between severe ABI group and control group(all P <0.05),but no statistical change between mild ABI group and control group(all P ＜0.05).The level of plasma NPY in ABI patients was significantly higher than that before injury,there was statistically different change between severe ABI group and mild ABI group,and it also had statistical change between severe ABI group and control group(all P＜0.05).The parameters of cardiac function was negatively correlated with the rise of plasma NPY by pearson correlation analysis(EF:r =- 0.79,P <0.01; SV:r =- 0.71,P <0.01;AV:r=-0.67,P ＜0.01 ;E/A:r =-0.63,all P ＜0.01)and(CO:r =- 0.32,P ＜0.05;CI:r =-0.35,all P ＜0.05). Conclusion The parameters of cardiac function were significantly decreased in the patients with acute brain injury,and it was closely related with the level of plasma NPY.
