BACKGROUND: According to Eysenck's theory of personality, trait level belongs tolow-grade personality, which can better reflect characteristics of individual habitual behavior reaction.OBJECTIVE: To explore the correspondent relationship between generalized anxiety patient and internal personality trait through adopting Cattell's 16 Personality Factor Questionnaire (16PFQ) and Zung's Self-rating Anxiety Scale (SAS) to test generalized anxiety patients.DESIGN: A transectional sampling survey and data was compared with that of health adult norms.SETTING: Counseling clinic of out-patient in the Southwest Hospital of the Third Military Medical University of Chinese PLA.PARTICIPANTS: Totally 100 patients with generalized anxiety disorders who visited the clinical counseling clinic of out-patient in the Southwest Hospital, Third Military Medical University of Chinese PLA for the first time from August 2003 to March 2004 were included, including 40 men and 60 women.METHODS: Catell's 16PFQ was tested with Psychometric Toolbox Standard Edition V2.3 developed by the Insight Group of Peking University.The patients filled out the forms independently after the method being explained clearly by professional staff members. These 16 personality factors included warmth (reserved vs. warm; Factor A), reasoning (concrete vs.abstract; Factor B), emotional stability (reactive vs. emotionally stable;Factor C), dominance (deferential vs. dominant; Factor E), liveliness (serious vs. lively; Factor F), rule-consciousness (expedient vs. rule-conscious;Factor G), social boldness (shy vs. socially bold; Factor H), sensitivity (utilitarian vs. sensitive; Factor I), vigilance (trusting vs. vigilant; Factor L),abstractedness (grounded vs. abstracted; Factor M), privateness (forthright vs. private; Factor N), apprehension (self-assured vs. apprehensive; Factor O), openness to change (traditional vs. open to change; Factor Q1), self-reliance (group-oriented vs. self-reliant; Factor Q2), perfectionism (tolerates disorder vs. perfectionistic; Factor Q3), tension (relaxed vs. tense; Factor Q4). Standard score of each observed index was measured automatically by computer measuring system. The standard score in Zung's SAS was (65.31±7.90).MAIN OUTCOME MEASURES: Comparison of standard scores in Cattell's 16PF between anxiety group and health adult norms.tell's 16PFQ for patients with generalized anxiety disorders: Scores in A,I, L, M, O, Q4 factor of anxiety patients were higher than that of health adult norms (6.19±1.69, 5.49±1.75;6.63±1.46, 5.53±1.84;5.84±1.52,5.47 ± 1.78; 6.22 ± 1.54,5.42 ± 1.61; 8.32 ±1.54,5.48 ±1.81; 8.10 ±1.27,5.60±1.99,(t=-2.03 to -13.15, P＜ 0.05-0.01)) while scores in B, C, E, F, G H,Q1, Q2, Q3 were significantly lower (5.22±1.46, 5.93±1.97;3.48±1.68,5.51±1.75;4.86±1.60, 5.53±1.83;5.01±2.22, 5.50±1.89;4.42±1.60,5.54 ±1.66 ;4.58±1.66, 5.56±1.84 ;4.64±1.29, 5.50±1.72 ;4.73±1.80, 5.50±1.72;and F had a significantly negative correlation with scores in Zung's SAS (r=-0.273,P ＜ 0.01 ;r=-0.217,P ＜ 0.05;r=-0.217,P ＜ 0.05) while factor Q4 had a significantly positive correlation(r=0.248 ,P ＜ 0.05).CONCLUSION: The development of anxiety with high scores in C, E, F and Q4 correlates with self-personality trait. These 4 personality traits may be susceptible factors in the development of anxiety disorder and may also affect its severity.

BACKGROUND: Major depression is a subtype of depression. Application of thymoleptics alone has bad effect. It has shown from relevant studies abroad that application of fluoxetine combined with atypical antipsychotic drugs maybe an effective treating strategy.OBJECTIVE: To observe the curative effects of fluoxetine combined with olanzapine and the time of its taking effect.DESIGN: Comparative study of open clinical test with completely random sampling for the first visit outpatients SETTING: A psychological consulting clinic in a hospital of a Military Medical College of Chinese PLA.PARTICIPANTS: Totally 140 patients visiting psychological counseling outpatient clinic in the hospital were collected from January 2004 to August 2004. Inclusion criteria: According to the diagnostic criterion of depression of CCMD-3, patients with total scores of 17 items in Hamilton depression rating scale≥28and age ≥18 years old .EXclusion criteria;①slight to middle edgree of depression(Hamt≤27);②secondary depression;③convalesscent period of schizophrenia and other affective disorder caused by psychosis;④severe of unstable body diseases ,including diseases of liver,kidney,cardiae vessel,respiration,gastro-intestine,endocrine,nervous system,innune system or hematological system,cet.⑤drug or alcohol addict;⑥women in pregnancy and lactation. Totally 110 patients accorded with the inclusive criteria. Among them, there were 40 males and 70 females with the course of disease for 4 months to 5 years, aged 18 to 63 with the average (37 ± 12) years old. They all took part in the trial voluntarily. According to the date of admittance, they were divided into odd-numbered date alprazolam group in which there were 55 patients with 21 males and 34 females and double date olanzapine group in which there were 55 patients with 19 males and 36 females.METHODS: The patients were divided into 2 groups according to the date of admittance. Odd-numbered date group was alprazolam group. 0.4 mg alprazolam was given every noon and before sleep and 20 mg fluoxetine was given at a draught after breakfast every day. Even-numbered date group was olanzapine group. 2.5 mg olanzapine was given before sleep every day and 20mg fluoxetine was given at a draught after breakfast every day. The course of treatment was 6 weeks. HAMD and HAMA scores of taken were evaluated respectively before and at the end of 1st, 2nd, 4th and 6th week. Reducing score rate was used to decide effective time. Lost rate was presented as percentage. And improvement of sleep factor and somatization factor in HAMD were observed before therapy and at every observing time period after therapy.MAIN OUTCOME MEASURES: Terminus index: Comparison of HAMD,HAMA score in the two groups before therapy and at the 1st, 2nd, 4th and 6th weekend after therapy. Scores of sleep factor and anxiety somatization factor of HAMD at every observing time period in the two groups. Substitution index: lost rate in the two groups. Reducing score rate at every observing time period in the two groups.RESULTS: Lost rate in olanzapine group was significantly lower than that in alprazolam group ( P ＜ 0.05) and the effect was taken at 1 week after therapy(excellence rate 67% ) . But, scores of HAMD and HAMA at every observing time period in olanzapine group were significant lower than those in alprazolam group( P ＜ 0.01) and sleep factor and somatization factor at every observing time period improved more significantly than those of alprazolam group( P ＜ 0. 01).CONCLUSION: Small amount of olanzapine combined with fluoxetine used to treat major depression of the patients can improve sleep and anxiety body symptoms rapidly and then elevate their living quality significantly.

Objective To evaluate the efficacy and effective time of low dosage of olanzapine combined with fluoxetine in treatment of major depression. Methods A total of 53 patients who suffered from major depression diagnosed according to CCMD-3 and the score of Hamilton rating scale for depression (HAMD) over 28, were randomly divided into 2 groups: alprazolam group (0.4 mg alprazolam, 2/d and 20 mg fluoxetine, 1/d), olanzapine group (2.5 mg olanzapine, 1/d, and 20 mg fluoxetine, 1/d). The treatment period lasted six weeks and the subjects were evaluated by using HAMD and HAMA at week 1, 2, 4, 6. The effective time was estimated by decreasing rate of the scale of HAMD and the amelioration of sleep disturbance and anxiety/somatization in HAMD were observed before and during the treatment. Results The therapeutic effects in olanzapine group at week 1 were observed with the apparent rate of 67%. The scores of HAMD and HAMA in olanzapine group were obviously lower than those in alprazolam group at each time point. The sleep disturbance and anxiety/somatization of the patients in olanzapine group improved significantly as compared with those in alprazolam group. Conclusion Fluoxetine combined with olanzapine is a fast and effective method to treat major depression.

Clinical data of 150 patients with mild and 38 patients with severe confirmed influenza A/H1N1 were collected and retrospectively analyzed in this paper with descriptive epidemiology. Mild patients mainly presented with symptoms similar to seasonal influenza with few complications, however,persistent high fever, cough with bloody sputum expectoration, chest distress and short of breath manifested in severe patients with respiratory failure and acute respiratory distress syndrome in some cases. Proportion of obesity and underlying diseases in severe patients, who were at high risk for severe influenza A/H1N1, was higher than that in mild ones (P＜0. 05). Average course of the illness spanned five to 11 days in patient with mild influenza A/H1N1 with all cured, and 34 of severe cases discharged with better recovery and other four died with a case-fatality of 10. 5 percent.
