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 prepare and identify the andrographolide-hydroxypropyl-?-cyclodextrin(an- drographolide-HP-?-CD)inclusion compound.The tool ratio between andrographolide and HP-?-CD and the thermodynamic constants in inclusion were studied simultaneously.Methods The andrographolide- HP-?-CD inclusion compound was prepared with lyophilization technique.Meanwhile,the inclusion com- pound was identified by differential scanning calorimetry(DSC)methods,infrared spectrometry(IR),and X-ray diffraction(XRD),respectively.The tool ratio between host and guest moleculars and the thermo- dynamic constants during the inclusion process were also researched by phase solubility method.Results An 1:1 molar ratio inclusion complex of andrographolide with HP-?-CD could be formed at 25,35,and 45 C.The phase diagram was A_L type and the procedure of inclusion was a heat release process.Conclusion The solubility of andrographolide-HP-?-CD inclusion compound can be increased obviously by the above- mentioned preparing techniques.

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.
