Objective: To develop a computer game addiction inventory (CGAI) for Chinese college students. Methods:A primary inventory made by the authors was applied to 477 college students from 8 universities in Beijing for exploratory factor analysis, and then to 405 college students for confirmatory factor analysis. Results: After exploratory factor analysis, a questionnaire consisted of 33 items were established, which had four factors: dependence and addict behavior, emotion arousal, functional impairment, and shame and un-satisfaction. These four factors could explain 55.1 of the total variance, were confirmed by confirmatory factor analysis (?~2/df=2.304; IFI=0.885; CFI=0.884; NFI=0.813; RSMEA=0.057). The internal consistency of the questionnaire was good (r=0.77~0.94), the test-retest reliability was 0.907. Criteria validity shown by higher scores in addiction group than normal control was also satisfying. Conclusion: The CGAI has good psychometric features and could be applied to college students.

This study was undertaken to examine ncNOS IR in bladder after spinal cord injury (SCI). In the meantime, we determine rats bladder ncNOS IR following intravesical instillation of capsaicin after SCI. Adult Sprague Dawley rats and guinea pigs were randomly divided into normal group, sham injury group, spinal cord injury group (4～5weeks after T 8～9 transection). A dose of 1mmol/L intravesical capsaicin was instilled in a part of SCI rats. Bladders of all animals were divided into three tissue pieces: bladder base, bladder body and bladder dome,in which the distribution of ncNOS IR was examined. Spinal transection induced a significant ncNOS IR increase in guinea pig bladder base. In rats, the quantity of ncNOS IR did not differ between the two groups. Instillation of intravesical capsaicin can cause significant up regulation of rat bladder ncNOS IR after SCI. The increase of ncNOS IR in SCI animals bladder indicates that NO may play an important role in the regulation of micturition reflex after SCI. In SCI rats, ncNOS IR can significantly be up regulated by intravesical capsaicin instillation, suggesting that NO may act as a factor in the action of capsaicin.

Objective The current study was designed to observe the efficacy and toxicity of recombinant human interleukin-11 (rhIL-11) in prevention and treatment of chemotherapy-induced thrombocytopenia in patients with acute myelogenous leukemia. Methods The total of 21 acute myelogenous leukemia patients with chemotherapy-induced thrombocytopenia(

Objective To analyze the influence of radial neck fracture on the upper limb function in older children,and to evaluate the curative effect of plate fixation in the treatment of Salter-Harris Ⅱ type of radial neck fracture.Methods The clinical data of 16 older children with radial neck fractures who treated by T plate internal fixation were retrospectively analyzed.16 cases were closed fractures,merging radial nerve injury in 1 case,3 cases of distal humerus fractures,1 case with rib fractures,fractures were Salter-Harris Ⅱ type,adopt steel plate internal fixa tion.Results 1 6 patients were followed up for 9-1 8 months.X-ray healing time was 6-9 weekson average 7.6 weeks.No malunion and no healing,no case of epiphyseal injuries.1 patient appeared steel block forearm supination.Postoperative patients with forearm pronation were greater than 90° supination were greater than 60 °.No radial nerve injury.Evaluation results were good.Conclusion Clinical treatment effect of open reduction and plate internal fixation in the treatment of older children with Salter-Harris Ⅱ type of radial neck fracture is satisfactory.Surgical treatment not only can enhance the fracture stability,but also can do the elbow joint function exercise to prevent dysfunction much earlier.

Objective To explore the surgical types in fractures of the proximal femur by internal fixation. Methods One hundred and three cases of femoral peritrochanteric fracture underwent operation were studied retrospectively. According to AO classification, the cases of each type were treated by four methods of internal fixation: the cannulated compression screw, dynamic hip screw (DHS), anatomical plate and proximal femoral nail (PFN). Results All patients were followed up from 6 to 40 months. All fractures were healed. Complications occurred in 9 patients, including aseptic necrosis of the femoral head in 2, coax magna in 7. According to Sanders standard of function of joint, the final effect was satisfactory. Conclusion It is important to select different surgical types according the different peritrochanteric fracture separately.

AIM: To compare the difference of A-scan and lOL Master in intraocular lens power measurement.
●METHODS:Two hundred and twenty-six patients (230 eyes) with age-related cataract were included in the study. Before surgery, axial length was measured by A-scan and lOL Master respectively and corneal curvature was measured by auto refractometer. lntraocular lens power was calculated according to the SRK-T formula. Corneal curvature was measured by auto refractometer and the refractive outcome was performed by phoropter three months after cataract surgery.
●RESULTS:The mean axial length was (23. 48 ± 1. 94) mm measured by A-scan and (23. 75±1. 96) mm measured by lOL Master. There was significant difference between them ( P < 0. 05 ). After random grouping, the preoperative and postoperative mean corneal curvature in A-scan group was (43. 94±1. 81) D and (43. 98±1. 87) D respectively. There was no statistically significant difference between them (P>0. 05). And the results were (44. 10 ± 1. 57 ) D and ( 44. 11 ± 1. 58 ) D in lOL Master group. There was no significant difference between them (P>0. 05); The mean absolute refractive error (MAE) in A-scan group was ( 0. 47 ± 0. 27 ) D and in lOL Master group (0. 41±0. 19) D. The difference was significant (P<0. 05).
●CONCLUSION: lOL Master is proved to be slightly more accurate than A-scan for lOL power calculation.

Objective To investigate the symptoms and affecting factors of food intolerance among 903 adults.Methods Food special antibody(IgG)in human serum were examined by ELISA.Food Intolerance Health Assessment Questionnaire was used to assess positive rate of food intolerance and food intake habits.Chi-square test and Mann-Whitney test were used for data analysis.Results The ratio of food intolerance was 0.33％ to 28.13％.Intolerant foods include crab(28.13％),yolk(27.02％),milk (13.07％),soybean(11.96％),shrimp,tomato,corn,beef,rice,chicken,mushroom,wheat,and pork.The symptoms of nervous system(55.89％),digestive system(45.69％)and respiratory system(15.64％)were commonly seen.Prevalence of food intolerance in mental labors was lower than manual labors.Conclusion The most common intolerant food includes crab,yolk and milk.The symptoms of food intolerance are different.Manual labors are more susceptible to food intolerance.
