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.

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(

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 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.

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 study the single nucleotide polymorphisms (SNP) in 3 sites allele (T189M, R85H, C121W) of SCN1B and the association between gene distribution and epilepsy. Methods All 330 blood samples of refractory (80 cases), non-refractory (100 cases) epilepsy patients and healthy people (150 cases) were collected. Genomic DNA of leucocyte was extracted. SNPs of three sites allele of SCN1B were tested by allele-specific primer-polymerase chain reaction (ASP-PCR).Data were analyzed by SAS 8.1 statistical software. Results Epilepsy group and healthy group had significantly statistical difference in composition of 3 sites allele on single site genotype (x~2=11.19, 11.14 and 6.50, all P < 0.05).There was no statistical significance between refractory and non-refractory epilepsy group. On gene combination, in 27 different combinations of polymorphism, mutation frequency in 3 sites (CT + AG + CG) was highest in epilepsy group (18.40%).The next was one site in CT + GG + CC (16.80%).In healthy group, frequency of non-variant in CC + GG + CC was highest (16.67%), and the next was 2 sites in CT+ AG+CC (13.73%).Thirty-five cases in epilepsy group (28.80%) had 3 sites mutation compared with 10 cases in healthy group (9.71%), and their difference had statistical significance (x~2=12.54, P<0.05).Eighteen cases in refractory epilepsy group (30.51%) had 3 sites mutation compared with 21 cases in non-refractory epilepsy group (28.77%), and the difference had no statistical significance. Fifty cases in epilepsy group (40.00%) had 2 sites mutation compared with 41 cases in healthy group (40.20%), and there was no statistical significance between them; 25 cases in refractory epilepsy group (42.37%) had 2 sites mutation compared with 21 cases in non-refractory epilepsy group (28.71%), and their difference had no statistical significance. Conclusions Mutation, especially multisite mutation of SCN1B is relatively likely to cause epilepsy in human. Gene distribution and combination of three sites allele of SCN1B in refractory epilepsy is close to that in non-refractory epilepsy.

ObjectiveTo explore the features of the cleanliness change with time during the use of laminar operating rooms in order to establish reliable quality assurance system. MethodsTwo grade 3 lami-nar operation rooms were chosen to be tested after one and a half year and two and a half years, laser counter was used to detect the static particulates after cleaning for 30 minutes and 45 minutes. ResultsAfter the laminar operation room was used for one and a half years the amount of 0.5 μm particulates in indoor air was less than 350 per liter, and after two and a half years it's above 350 per liter after cleaning for 30 minutes, an obvious difference than the previous one. The anaount of 1 μm and 2 pan particulates also increase obviously, but ff cleaning for 45 minutes the amount of 0.5 μm particulates in indoor air will fulfill the qualification. Al-though the amount of 0.5 μm, 1 pan and 2 μm particulates after 2 years using was higher than the one and a half yesrs'using after cleaning for 45 minutes, but the difference had no statistic meaning. CondusionsThe elesnliness of laminar operation rooms will drop as time prolonged, Amount of particulates in indoor air will in-crease too but the cleanliness can be ensured by extending cleaning time. After the quality assurance sys-tem was established the amount of smile particulates is still within the standard level
