Objective: To explore the effect of psychotherapy in treating middle school students with IAD (internet addiction disorder). Methods: 23 cases of middle school students with IAD had been treated by cognitive therapy or behavior therapy. The IAD scale, SCL-90 scale and SDS scale were used to evaluate the effect before and after therapy. Results: After therapy, the total scores and most dimensions scores in IAD scale, SCL-90 scale and SDS scale decreased significantly than that before therapy. Conclusions: Psychotherapy especially cognitive therapy and behavior therapy is an effective in treating middle school students with IAD.

Objective: To evaluate hemostatic effects of a self-designed rapid-hemostatic-dressing (RHD) on bleeding of the partially ruptured superior sagittal sinus in dogs. Methods: Bleeding models of the partially ruptured superior sagittal sinus were established in 15 dogs by gunshot and surgery. The 15 model dogs were divided into 2 groups: RHD group (n=10) and control group (treated with surgicel, n=5). The survival time, blood loss, and other hematological parameters were measured over a 1-hour period. Results: The bleeding models of the partially ruptured superior sagittal sinus were successfully established in dogs. There were no significant differences in the baseline parameters of dogs compared with those 60 minutes after RHD treatment. The survival time in RHD group was significantly longer than that in control group and the blood loss was significantly lower than that of the control group (both P<0.05). Conclusion: RHD has satisfactory hemostatic effects on partially ruptured superior sagittal sinus in dogs, indicating it is an excellent hemostatic dressing.

Objective To investigate the distribution and drug resistance of the gram positive bacteria isolates from hospital in Chongqing during 2006-2011 .Methods Non-repetitive gram positive bacterias were collected retrospectively from ten hospitals in Chongqing .Antimicrobial susceptibility testing of all clinical isolates were carried out using Kirby-Bauer(KB) .Results 14 473 strains were isolated .There were 4 840 strains of Staphylococcus aureus (33 .4% ) ,2 566 strains of Staphylococcus epidermidis (17 .7% ) ,1 822 strains of Staphylococcus haemolyticus (12 .6% ) ,1 325 strains of Enterococcus (E .faecalis/E .faecium )(9 .2% ) . Staphylococcus was highly sensitive to nitrofurantoin ,rifampicin ,piperacillin/tazobactam ,linezolid ,teicoplanin and vancomycin ,but their resistance rate to ampicillin/sulbactam ,oxacillin ,penicillin and clarithromycin was high .The resistance rate of E .faecium to the majority of antimicrobial agents was obviously higher than that of E .faecalis ,excluding imipenem ,chloramphenicol and tetracy-cline .Vancomycin and linezolid still remain the strongest antibacterial activity to Enterococcus .Conclusion The distribution and drug resistance of pathogenic bacteria in Chongqing present regional particularity ,and antibiotic resistance is severe .It is significant to strengthen the epidemiology study of pathogenic bacteria and to develop policies to intervene in the use of antimicrobial agents .

Objective: To construct a three-dimensional (3D) anatomic model of the lateral ventricles for teaching microneurosurgical anatomy and clinical surgery planning. Methods: The 3D model was constructed with a series of 176 MRIT2 head sections of a healthy male volunteer (36 years old) using software Matlab, Geomagic, Maya, etc. The 176 sections were subjected to management with software Matlab for image preprocessing and contour extracting; the acquired contours were subjected to software geomagic for 3D model constructing,3D-model and image connecting and other processings. Results: The 3D model of the lateral ventricles and related structures were successfully constructed using more than 240,000 remodeled polygons, and the contour of the model consisted well with the images. The model had a even better visual effect after combining the 3D-model and image. The model could be viewed from any angle and could be rotated by 360 degrees in any plane using any structure as the focal point of rotation. Moreover, the model could be reduced or enlarged using the zoom function. Conclusion: The constructed 3D model can be observed and studied repeatedly at any time, with no stress from surgery. The model may be used for interactive surgical exercises, paving a way for subsequent clinical practice.
