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. Single factor analysis results were indicated that the scores of QOL between the different gender, occupation, marital status age,education were remarkable difference(all P

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.

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.

Objective To investigate the effects of sevoflurane postconditioning on cardiomyocyte apoptosis during myocardial ischemia-repeffusion (I/R) in rats.Methods Forty-five healthy male Wistar rats weighing 250-280 g were randomly divided into 3 groups ( n =15 each):group sham operation ( group S) ; group I/R and group sevoflurane postconditioning (group Spo).The animals were anesthetized with intraperitoneal 3％ pentobarbital 45 mg/kg,tracheally intubated and mechanically ventilated.Myocardial I/R was produced by occlusion of anterior descending branch of left coronary artery for 30 min followed by 120 min reperfusion in groups I/R and Spo.In group Spo the animals inhaled 2.5％ sevoflurane for 5 min starting from 1 min before reperfusion was started.The animals were sacrificed at the end of 120 min reperfusion.Their hearts were removed for measurement of infarct size and the area at risk and determination of apoptotic index (the number of apoptotic cells/the total number of cells) and Bcl-2 and Bax protein and mRNA expression.Results Sevoflurane postconditioning significantly reduced infarct size in group Spo as compared with group I/R.There was no significant difference in area at risk between groups I/R and Spo.Myocardial I/R significantly increased the apoptotic index,Bcl-2 and Bax protein and mRNA expression in group I/R as compared with group S.Sevoflurane postconditioning significantly decreased apoptotic index and Bax protein and mRNA expression but increased Bcl-2 protein and mRNA expression in group Spo as compared with group I/R.Conclusion Sevoflurane postconditioning attenuates myocardial I/R injury by redncing myocardial apoptosis,up-regulating Bcl-2 expression and down-regulating Bax expression.

AIM:To clarify the mechanism of treating autoimmune cardiomyopathy at different stages with anti-L3T4 monoclonal antibody.METHODS:Mice immunized with human mitochondria ADP/ATP peptides were used as the cardiomyopathy(DCM) group,and the sham-immunized mice were regarded as the controls.Mice receiving early treatment were immunized with the same peptides,followed by the injection of 400 ?g of anti-L3T4 on day 0,1 and 2 post-immunization.Mice in the late treatment group were immunized as of the early treatment group but anti-L3T4 was administered 3 months post-immunization.The cytokine expression was measured with three-color flow cytometry to quantitate the splenic Th1/Th2 cell subsets in the different groups of mice.In addition,serum and myocardial cytokines were measured by enzyme-linked immunosorbent assay and real-time PCR.RESULTS:Th1 and Th2 subsets in the early treatment group were similar to those in control group,but were drastically lower than those in DCM group.Mice in the late treatment group showed an increased level of Th1-related cytokines,while the Th2 level was between the DCM and early treatment group.IFN-? and IL-6 levels in early treatment group were similar to those in control group.In the early treatment group,IL-4 level was higher than that in control and lower than that in DCM group,whereas IL-2 and TNF-? contents were lower than those in control and DCM group.In the late treatment group,IFN-? and IL-2 levels were higher than those in DCM group and lower than those in the early treatment group,while IL-6 and IL-4 levels were lower than those in DCM group.CONCLUSION:These results suggest that the cytokine production in cardiomyopathic mice may be repressed by treatment with anti-L3T4 at different stages.Early treatment with anti-L3T4 has better inhibitory function than treatment in late stage of autoimmune cardiomyopathy.

AIM: To investigate the changes of the L-type calcium channel subunit expression and calcium currents (I_~Ca -L) in cultured rat ventricular myocytes infected by coxsackie virus B_3 (CVB_3). METHODS: Primary cultured neonatal rat ventricular myocytes were infected with CVB_3. The changes of L-type calcium channel subunits mRNA in normal and infected myocytes were measured by semi-quantitative reverse transcription-polymerase chain reaction. I_~Ca -L was recorded in two groups respectively using whole cell patch-clamp techniques. RESULTS: The expression of ?_1 and ? subunits of L-type calcium channel mRNA increased in the infected group compared with the normal one (4.00?0.07 vs 2.21?0.41, P0.05). The average current density of I_~Ca -L significantly increased by CVB_3 infection [(-8.66?0.99) pA/pF vs (-6.97?1.75) pA/pF, P
