Objective: To observe the clinical effect of Sertraline in treatment of dysthymia. Methods:63 outpatients diagnosed as dysthymia according to ICD-10 were randomly assigned to study group (n=33) and placebo group. Randomized double blind control study was done for 8 weeks with Sertraline from 50-200 mg/d. HAMA and HAMD were used to assess the effect.Results:At the end of 8 weeks, 54 patients completed the trial. Patients of both groups had lower HAMD scores than baseline from 2 weeks, and this trend continued through the 8 weeks observation. During this period, HAMD score of the study group declined more significantly than that of the placebo group. At the end of 8 weeks, the score of HAMA of the study group was also lower than that of the placebo group. The side effects of Sertraline were mild.Conclusion:Sertraline is effective in treatment of psychiatric outpatients with dysthymia.

Objective To investigale the quality of life (QOL) and its influenced factors in Tibetan patients with generalized tonic clonic epilepsy.Methods QOL of 126 definit diagnosed Tibetan patients with generalized tonic clonic epilepsy were measured with the QOL in Epilepsy Inventory-31 (QOLIE-31). The influenced factors of QOL were analysed. Results The total score of QOLIE-31 was 48.58?17.29; the lowest subcomponent score was 32.92?22.97 for Seizure Worry ; the highest was 77.11?20.98 for Medication Effects.

Objective To evaluate the effects of Taoist cognitive psychotherapy on depression of aged patients with cerebral stroke hemiplegia convalescence. Methods Seventy-seven hemiplegia convalescence patients with depression were divided into general treatment group (38 patients, received general back-up psychology therapy) and combined treatment group (39 patients, received general back-up psychology therapy and Taoist cognitive psychotherapy) by random digits table. All patients were treated for 8 weeks and followed up for 6 months. Two groups were evaluated with HAMD and SS-QOL before treatment and at the end of the 2 weeks,4 weeks, 8 weeks and 6 months after treatment. The results were analyzed with statistics. Results In general treatment group, the HAMD scores were gradually decreased, and the HAMD scores of patients after 8 weeks' treatment were significantly lower than those before treatment[(22.35 ± 4.69)scores vs. (29.62 ± 5.95 ) scores,t = 6.425 ,P ＜ 0.01]. At the end of 6 months after treatment, the scores increased [(24.48 ± 4.12 ) scores vs. (22.35 ± 4.69 ) scores, t = 2.014, P ＜ 0.05], but they were lower than those before treatment(t = 4.836, P ＜ 0.01 ). At the end of 6 months after treatment, the SS-QOL scores were lower than those after 8 weeks' treatment (t =2.543,P ＜0.05),but they were higher than those before treatment (t = 2.790,P ＜ 0.05 ). In combined treatment group, the HAMD scores decreased continuously,and the scores after 8 weeks' treatment [(20.08 ± 4.60) scores] and 6 months' treatment [( 15.21 ± 3.42)scores] were significantly lower than those before treatment [( 30.14 ± 4.92 ) scores] (t = 8.341,15.443, P ＜0.01). Meanwhile,the HAMD scores after 6 months'treatment were significantly Iower than those after 8 weeks' treatment (t =4.724,P ＜ 0.01 ). The SS-QOL scores after 8 weeks' treatment [( 117.56 ± 26.22)scores] and 6 months' treatment [(126.57 ±21.82) scores] were significantly higher than those before treatment[(86.54 ± 23.90) scores] (t = 6.716,8.916,P ＜ 0.01 ) ,and there was significantly difference(t=2.378,P ＜ 0.05). The HAMD scores of combined treatment group after 8 weeks' and 6 months' treatment were significantly lower than those of general treatment group at the same time(t = 2.118, P ＜ 0.05 ;t = 8.405,P＜ 0.01 ) ,and SS-QOL scores were significantly higher than those of general treatment group at the same time (t = 3.123,P ＜ 0.05 ;t = 6.580,P ＜ 0.01 ). Conclusions General back-up psychology therapy combined with Taoist cognitive psychotherapy can improve depression and life quality of cerebral stroke hemiplegia convalescence in aged patients. The effects of Taoist cognitive psychotherapy is slower, but it is more beneficial in the long time.

Aim To explore the effects of acupuncture and sinomenine on the withdrawal symptoms,on the spontaneous discharge and synaptophysin expression of amygdala of heroin-addicted rats.Methods 75 SD rats were randomly and equally divided into 5 groups consisted of control,heroin-addicted,acupuncture,sinomenine and combined treatment group.The model of heroin-addicted rats were established with heroin subcutaneous injection,which in acupuncture,sinomenine and combined group were subsequently punctured at 3 acupoint(Neiguan,Baihui and Zusanli),intramuscular injected with sinomenine and treated with combined methods(acupuncture and sinomenine)respectively.The withdrawal symptoms of rats in different group were evaluated,and then the spontaneous discharges and synaptophysin expression of amygdala were detected with electrophysiological and immunohistochemical technology respectively.Results The heroin-addicted rats were successfully established,being suggested by typical withdrawal symptoms induced by naloxone(P<0.01 vs control),which were alleviated in the 3 treatment groups(acupuncture,sinomenine and combined ) with varying degree(P<0.01 vs heroin group).The electrophysiological results suggest that the forms of low-frequency and single irregular discharges in amygdala were increase,bunchy/cluster and complex discharges were decreased(P<0.05 vs control),which were reversed apparently in sinomenine and combined treatment groups(P<0.05 vs heroin group),closed to control.The immunohistochemical results show that expression of synaptophysin in amygdala was increased obviously(P<0.01 vs control),which was decreased in the 3 treatment groups(acupuncture,sinomenine and combined),P<0.01 vs addicted group.Conclusion Treatments of acupuncture and sinomenine administration can alleviate withdrawal symptoms of heroin-addicted,and rectify the abnormal spontaneous discharges and expression of synaptophysin in amygdala of heroin-addicted rats for certain degree,especially with combined treatments.
