Objective:To screen the issues of management for radiation therapy equipment in an academic hospital with Delphi method.Methods: 6 specialists with different background were consulted with the questionnaire, and those questions were screened from questionnaire as being scored with the importance and analyzed by SPSS software.Results: 6 specialists included 2 radiation managers, 3 radiation professionals and 1 health administrative personnel. The authority coefficient was 0.88±0.06, and the activity coefficient was 100%. The Kendall concordance coefficient wereW=0.019(P=0.635) andW=0.237(P=0.001) in the 1st and 2nd round respectively. The coordination of the expert’s opinions was good and the results of the questionnaire were credible. There were 18 questions got from the questionnaire based on the averages and standard deviations.Conclusion: It was effectiveness that Delphi method can screen the issues of management for radiation equipment, on which we can get the direction of performance improvement based.

Objective To observe the effect of ankle-foot orthosis(AFO)on the activities of daily living(ADL)and walking ability of patients with low lumbar spinal cord injury.Methods29 cases with low lumbar spinal cord injury were trained by systematic rehabilitation.According to patients' condition,static AFO or dynamic AFO were assembled for them.All patients were evaluated with Modified Barthel Index(MBI)and Functional Independence Measure(FIM)before and after training,and the walking distances were also measured.ResultsAfter AFO dressed,the ADL scores of patients increased,especially walking ability increased significantly(P<0.05).Of 29 patients,26 cases had outdoor walking ability,3 cases had domestic walking ability.ConclusionSelecting different kinds of AFO according to condition of individual can help patients with low lumbar spinal cord injury to reconstruct their walking ability and improve ability of self-management.

Objective To investigate the effect of continuous passive motion(CPM) and rehabilitation on flexion of the shoulder after intensive burn.Methods 36 patients with intensive burn on upper limb(including the skin around axilla fossa) were divided randomly into CPM group(n=19) and control group(n=17).The CPM group received both routine rehabilitation and continuous passive motion treatment,and the control group only underwent routine rehabilitation treatment.Their ranges of active or passive motion were assessed.Results There was a significant improvement both in the CPM group and the control group after treatment(P<0.01),but the CPM group improved more(P<0.05).Conclusion CPM can improve the efficacy of the routine rehabilitation on flexion of the shoulder after intensive burn.

Objective To analyze the expression of Yes-associated protein and risk factors in differentiated thyroid carcinoma. Methods Clinical data of 152 patients with differentiated thyroid carcinoma and 27 cases of benign thyroid tumor from Changji Hui Autonomous Prefecture People’s Hospital of Xinjiang, were analyzed retrospectively. According to the expression levels of Yes-associated protein in differentiated thyroid cancer and benign thyroid tumor, univariate Chi-square test and multivariate Logistic regression methods were used to analyze the relationship between Yes-associated protein and gender, age, thyroid stimulating hormone(TSH) level, nodule size, capsule integrity, histological type and lymph node metastasis, in order to find out risk factors in differentiated thyroid cancer. Results The positive rate of expressed Yes-associated protein in benign thyroid tumor group was 66.7%(18/27), which was significantly higher than 31.58%(48/152) of differentiated thyroid cancer group, and the difference was statistically significant(χ2=12.127, P<0.01). Under an optical microscope, changes of Yes-associated protein were found to be mainly located in the nucleus and cytoplasm , and in benign thyriod tumor the degree of staining was deep, strong positive or moderately positive; differentiated thyroid carcinoma was lightly stained or no staining, weakly positive or negative. Chi-square test showed that the expression of Yes-associated protein was not affected by sex, age and pathological type(χ2= 0.419, 0.221, 0.315, all P >0.05); TSH level, nodule size, capsule integrity, lymph node metastasis had an impact on the expression of Yes-associated protein which was down regulated (χ2=4.020, 8.424, 4.386, 6.673, P<0.05 or<0.01). Logistic regression analysis showed that the nodule size was not a risk factor ( odds ratio , OR ) of Yes-associated protein expression (OR=1.929, P>0.05); TSH levels above 4.5 mU/L, lymph node metastasis and envelope incomplete were risk factors that down regulated the expression of Yes-associated protein (OR=2.167, 2.665, 3.048, all P<0.05). Conclusion Yes-associated protein is down regulated in differentiated thyroid cancer. Elevated TSH levels , incomplete capsule and lymph node metastasis are risk factors of Yes-associated protein down expression and differentiated thyroid cancer.

Objective To explore the effect of amphetamine on eukaryotic translation elongation factor 2 (eEF2) in the frontal cortex of mice.Methods Male C57BL/6 mice were randomly divided into normal control group (n=10),saline group (n=10) and amphetamine treatment group (n=40);the amphetamine treatment group was divided into 1,7,14 and 28 d subgroups (n=10).Mice in the amphetamine treatment group were treated with amphetamine 2 mg/(kg· d) via intraperitoneal injection;those in the saline group received a same dose of saline,while those in the normal control group received no treatment.Autonomous behavior activities were tested during establishing amphetamine models.Immunohistochemistry and Westem blotting were used to identify the eEF2 expressions.Results Behaviour test showed that total moving distance,average speed,maximum speed,moving fast time/total time in the 7,14 and 28 d amphetamine treatment subgroups were significantly increased as compared with those in the normal control group and saline group (P＜0.05).Immumohistochemical staining indicated that the grey values of eEF2-positive inummoreactive products in the amphetamine treatment group were significantly lower than those in the normal control group and saline group (P＜0.05);those of eEF2-positive inummoreactive products in 14 and 28 d amphetamine treatment subgroups were significantly lower than those in 1 and 7 d amphetamine treatment subgroups (P＜0.05).Western blotting showed that eEF2 protein expression in the frontal cortex was significantly elevated in the amphetamine treatment group as compared with that in the other two groups (P＜0.05);the eEF2 expression in the amphetamine treatment group increased with time prolonging within 28 days after establishment of models.Conclusion Amphetamine can induce increased eEF2 expression in the frontal cortex of mice.

Trauma registration is an important tool to record the process and timeline in the treatment of trauma patients. The operation of trauma database is of great significance for reducing the mortality of patients, promoting the construction of trauma treatment system, and providing reference for policy-making. Trauma registration system has been established in the United States, United Kingdom, Germany and other developed countries for many years. However, the domestic system is still at an initial stage, and there are problems like data deficiencies, data incoherence, no item of complications, no treatment data after discharge and limits of human and financial resources. Therefore, there is room for improvements in terms of personnel fixation, financial support and continuous data monitoring should be further improved. In this study, the authors summarize the traum registration system from aspects of basic situation both at home and abroad, data analysis, clinical value, operation mechanism and challenges so as to provide important data for clinical researches.
