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 .

Aminoacyl-tRNA syntheses (AARS) can catalyze the adenosine triphosphate (ATP)-dependent acylation of their cognate tRNA(s) with a specific amino acid. They can be seen as an index to reflect the energy metabolic rate of ischemic brain cells in ischemic penumbra. This study examined the relationship between arginyl-tRNA synthetase (ArgRS), one of the AARS, and cerebral ischemia in rats. The model of middle cerebral artery occlusion (MCAO) was established in rats. The expression levels of ArgRS protein and mRNA were detected in rat brain tissues at different time points following MCAO by Western blotting and RT-PCR, respectively. The results showed that the MCAO model was successfully established. Western blotting and RT-PCR analysis revealed that the ArgRS protein and mRNA were expressed in brain cells in both ischemic and normal penumbra tissues. The expression levels of ArgRS protein and mRNA peaked at 6 h after MCAO and decreased gradually. At 24 h, the expression levels of ArgRs protein and mRNA in ischemic penumbral tissues were lower than those in normal tissues. The expression levels of ArgRS mRNA and protein in ischemic penumbra varied with ischemic time, suggesting that the energy metabolism of brain cells in penumbra changed dynamically after ischemia to ensure the endogenous self-protection of the body. The brain oxygen supply should be improved as soon as possible, especially within 6-12 h after ischemia, so as to meet the demand for energy metabolism in ischemic penumbra and make sure the cell structure remains stable.

Objective To investigate the relationship of Vaneomycin serum concentration and drug adverse reactions (ADRs) in neonates.Methods Two hundred and thirteen neonates who were treated by Vancomycin and had their serum concentration monitored were recruited.The number of cases which had liver,kidney and hearing damage after treatment was calculated.The correlation between 3 different serum concentrations (＜5 mg/L,5-10 mg/L,＞ 10 mg/L) and ADRs were analyzed.Results The mean level of Vancomycin in serum was (4.36 ± 4.99) mg/L The total incidence of ADRs was 17.8％ (38/213 cases).The main ADRs were liver damage and hearing impairment,whose incidences were 9.9％ (21/213 cases) and 7.5％ (16/213 cases),respectively,and they were were significantly higher than kidney danage (0.5％,1/213 cases) (x2 =19.172,P =0.000;x2 =13.785,P =0.000).There was no significant difference be-tween the inidence ratio of liver damage and that of the hearing impairment (x2 =0.330,P =0.566).The ADRs ratio among 3 different serum concentrations was 17.0％ (24/141 cases),17.6％ (9/51 cases) and 23.8％ (5/21 cases).There was no significant difference between the ADRs ratios and distribution of different serum concentrations (x2 =0.576,P =0.750).Moreover,the ADRs rates didn't increase along with the serum concentrations (Z =0.648,P =0.517).Except for aspartate transaminase,the indicators of liver and kidney function varied significantly after vancomycin treatment (P ＜0.05).But there was no clinical significance because the mean value was in normal range.By Bivariate Correlation analysis,Vancomyein serum concentration had no significant influence on liver and kidney function (P ＞ 0.05).Conclusions Neonates treated by Vancomycin had reatively high ratio of the liver damage and the hearing impairment.There is no significant correlation between Vancomyein serum concentration and ADRs in neonates.

Prolyl-4-hydroxylase domain (PHDs) family is one of the most important regulatory factors in hypoxic stress. PHD2 plays a critical role in cells and tissues adaptation to the low oxygen environment. Its hydroxylation activity regulates the stability and transcriptional activity of the hypoxia-inducible factor 1 (HIF-1), which is the key factor in response to hypoxic stress. Subsequently, PHD2 acts as an important factor in oxygen homeostasis. Studies have shown that PHD2, through its regulation on HIF-1, plays an important role in the post-ischemic neovascularization. Furthermore, under hypoxic condition, PHD2 also regulates other pathways that positively regulate angiogenesis factors HIF-1 independently. Moreover, recently, several evidences have also shown that PHD2 also affects tumor growth and metastasis in a tumor microenvironment. Based on these facts, PHD2 have been considered as a potential therapeutic target both in treating ischemic diseases and tumors. Here, we review the molecular regulation mechanism of PHD2 and its physiological and pathological functions. We focus on the role of PHD2 in both therapeutic angiogenesis for ischemic disease and tumor angiogenesis, and the current progress in utilizing PHD2 as a therapeutic target.
