Objective:To explore the clinical effect of group psychotherapy on relieving anxiety and depression symptoms in patients with alcohol dependence.Methods:Totally 117 patients with alcohol dependence accompanied with anxiety and depression symptoms were selected from the Second People's Hospital of Puer City from 2014 January 1 to December 31.The anxiety and depression symptoms were assessed with the Self-Rating Anxiety Scale (SAS),Self-Rating Depression Scale (SDS) and Brief Psychiatric Rating Scale (BPRS).They were divided into drug combined group (intervention group,n =89) and single drug treatment group (control group,n =88).The two groups were administrated diazepam replacement therapy,and the intervention group combined group psychotherapy.Eight weeks later,treatment effect of the two groups were evaluated with the Clinical Global Impression Scale (CGI).Results:After intervention,the scores of SAS,SDS,BPRS,and CGI in intervention group decreased [(21.1 ±8.3) vs.(65.3± 10.2),(35.1 ±3.5) vs.(51.7 ±5.6),(4.3 ± 1) vs.(5.4 ±0.6),Ps <0.05].There was no significant difference in above scores between before and after treatment in the control group (Ps > 0.05).Conclusion:The effect of group psychotherapy on the basis of medicine may be better than that of single drug therapy on relieving anxiety and depression in patients with alcohol dependence.

In order to suppress the geometrical artifacts caused by random jitter in ray source scanning, and to achieve flexible ray source scanning trajectory and meet the requirements of task-driven scanning imaging, a method of free trajectory cone-beam computed tomography (CBCT) reconstruction is proposed in this paper. This method proposed a geometric calibration method of two-dimensional plane. Based on this method, the geometric calibration phantom and the imaging object could be simultaneously imaged. Then, the geometric parameters could be obtained by online calibration method, and then combined with the geometric parameters, the alternating direction multiplier method (ADMM) was used for image iterative reconstruction. Experimental results showed that this method obtained high quality reconstruction image with high contrast and clear feature edge. The root mean square errors (RMSE) of the simulation results were rather small, and the structural similarity (SSIM) values were all above 0.99. The experimental results showed that it had lower image information entropy (IE) and higher contrast noise ratio (CNR). This method provides some practical value for CBCT to realize trajectory freedom and obtain high quality reconstructed image.
