ABSTRACT
Objective To assess the latency and amplitude changes in P300 in senile patients with depression.Methods 13 domestic published study literatures meeting our criteria were searched from CBM,CNKI,and a meta-analysis on P300 latency and amplitude was performed with RenMan 4.1 soft ware.Results 1.The P300 latency in senile patients with depression was significant longer than that in senile normal controls in N1,P2,N2,P300 (N1:WMD=3.07,95 ％ CI:0.7～5.42,Z=2.55,P=0.010;P2:WMD=18.41,95％CI:15.11～21.71,Z=10.93,P＜ 0.01;N2:WMD=25.41,95％CI:12.80～29.02,Z=13.80,P＜0.01;P3:WMD=32.14,95％CI:24.14～34.88,Z=23.04,P＜0.01).2.The amplitude in senile patients with depression was significant lower than that in senile normal controls in N2,P2,P3 (P2:WMD=-0.83,95％CI:-1.07～-0.59,Z-6.78,P＜0.01; N2:WMD＝-0.34,95％CI:-0.59～-0.08,Z=2.57,P=0.01;P3:WMD=-2.54,95％CI:-2.75～-2.33,Z=23.99,P＜0.010).Conclusions P300 longer latency and lower amplitude are the statistically characterized features for senile depressive patients.
ABSTRACT
Objective To observe the effect of SSRI combined with TCM on the treatment of depression of different TCM types. Methods 70 depressive patients of stagnation of liver qi (SLQ) were randomly recruited into a study (34 cases) and a control group (36 cases); 60 depressive patients of spleen deficiency and liver qi stagnation (SDLQS) were randomly recruited into a study (30 cases) and a control group (30 cases); and SO depressive patients of deficiency of both heart and liver (DBHL) were randomly recruited into a study (24 cases) and a control group (26 cases). Patients in the study group were treated with SSRI and TCM; with the control group was only treated with SSRI. All patients were assessed with HAMD, HAMA and CGI before treatment and after treatment at 1st weekend, 2nd weekend, 4th weekend and 6th weekend. Differences of effective rate and full remission rate were contrasted. Results ①Scores of depression scale decreased in both the study group and the control group of patients with SLQ and SDLQS at the 4th [SLQ study group: (9.01±3.45), control group (13.02±4.54); SDLQS study group (10.22±3.23)、 control group (14.12±3.87)] and 6th [SLQ study group (6.02±2.20), control group (10.22±2.10); SDLQS study group (7.25±2.20) control group (10.68 ± 3.45)] weekend, showing statistical differences; anxiety state has been improved since the 1st weekend; no obvious changes of HAMD and HAMA showed in both the study group and the control group of patients with DBHL; ②Therapeutic effects in the study group were higher than the control group of both patients with SLQ and SDLQS, showing statistical significance; while no difference can be seen between the two group of patients with DBHL; ③ No differences of full remission rate between the study group and the control group of 3 TCM types were found(SLQ:41.1%v30.6%,χ2=0.859,P>0.05; SDLQS:40.0%v33.3, χ2=0.287,P>0.05; DBHL: 33.3%v26.9%,χ2=0.244,P>0.05). ④Significant differences of HAMD and HMDA between the study and the control group of 3 TCM types were found before and after treatment Conclusion SSRI integrated with TCM may promote effective rate and decrease anxiety in patients with SLQ and SDLQS.
ABSTRACT
Objective:To compare the differences in incidences of insomnia,anxiety(irritability)and manic ep- isode induced by fluoxetine and amitriptyline in treating depression.Method:CBM discs were selected for the data sources. The rates of insomnia,anxiety(irritability)and manic episode from published clinical control trials on depression treated by fluoxetine and amitriptyline were analyzed by applying fixed effect model(FEM)of evidence-based medicine(EBM). Result:Of 1205 cases in 15 studies,the rates of insomnia induced by fluoxetine or amitriptyline were 21.71% and 1.80% ,OR 9.39(95 %CI 5.37-16.44),P0.05.Conclusion:Fluoxetine induces in- somnia and anxiety(irritability)more easily than amitriptyline when treating depression.
