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 .

X-Ray tube is the core part of CT machines and its service life is closely tied to its quality,installation & adjustments and the status of the equipment itself.Besides,whether the operaters use the equipment correctly or not also influence the life of X-ray tubes.The author summarizes some methods for extending the life of CT tubes according to the experiences of installation,adjustment and using of the CT tubes for many years.

AlM:To investigate the expression transforming growth factor-β1 (TGF-β1) and heat shock protein 47 (HSP-47), in pterygium and normal conjunctiva tissues, in order to study the roles of these cytokines played in the pathogenesis in human pterygium.
METHODS:The expression difference of TGF-β1, HSP-47 between human pterygium and normal conjunctive tissues were compared by immuno - histochemistry technique.
RESULTS:The positive expression of TGF-β1, HSP-47 was stronger than in normal conjunctive tissues ( P <0. 05), the TGF-β1 expressed in all layers of pterygium, especially in the squamous epithelium, in the inflammation cells and vascular endothelial cells also expressed. The HSP-47 showed higher expressed in the lamina propria layer of pterygium, and weakly expressed in epithelial layer, no obvious expression in normal conjunctive tissues.
CONCLUSlON:Over-expression of TGF-β1 and HSP-47 in pterygium compared to the normal conjunctiva tissues may play a critical role during the occurrence, development and invasion of the pterygium.
