ObjectiveTo evaluate the reliability and validity of the of Disability Assessment Schedule Ⅱ of World Health Organization(WHO-DASⅡ) applied in assessment of the function of disabled athletes.Methods56 disabled people,26 wheelchair basketball athletes and 30 patients,were sampled and completed WHO-DASⅡ questionnaire.The test and re-test had been administrated in 10 days.Barthel Index(BI) and Sports Classification Test had been implemented for the functioning assessment.ResultsThe test-retest reliability for WHO-DASⅡ in six dimensions were: 0.978,0.807,0.938,0.877,0.998,0.935,0.986 and all were in very significant level(P<0.01).There were negative correlation between WHO-DASⅡ scores and BI in total and in every dimension,the correlation coefficients were:-0.77,-0.17,-0.71,-0.82,-0.33,-0.73,-0.61.The correlation coefficients between WHO-DASⅡ total and six dimensional scores and the grade of sports classification were:-0.741,-0.378,-0.806,(-0.541),-0.293,-0.510,-0.677.ConclusionWHO-DASⅡ can be used in assessing the function of disabled athletes.

0.05),including seven with spinal kyphosis,seven with thoracic deformity,five with pleural effusion,five with emphysema diagnosed by chest X-ray film,three with spontaneous pneumothorax,two with diaphragmatic hernia,and one developed severe respiratory failure and the other developed cot pulmonale.Conclusions The thorax,lungs and diaphragm were more easily involved in the patients with Marfan syndrome,and pulmonary specialists should keep an eye on them.

Objective To detect the infection of human papillomavirus (HPV)in patients with non-small cell lung cancer (NSCLC)and explore the relationship between HPV infection and clinicopathological features.Methods HPV detection and genotyping in 156 cases of NSCLC were performed using a new liquid chip based on Luminex.Patient clinical characteristics were also recorded,and the relationship between HPV infection and clinicopathological features was studied.Results Of the 156 tumor-DNA samples tested,40 (25.6%)cases showed presence of HPV-DNA,of which 37 cases were of a high-risk HPV type (16,18,33, 58).The differences were statistically significant between the HPV-positive and HPV-negative groups in gender (χ2 =4.387,P =0.036),smoking (χ2 =8.130,P =0.004),histologic type (χ2 =4.075,P =0.044)and lymph node metastasis (χ2 =7.082,P =0.008).The differences were not statistically significant between the HPV-positive and HPV-negative groups in age (χ2 =0.013,P =0.910),differentiated degree (χ2 =1.727, P =0.189),clinical stages (χ2 =0.179,P =0.672),distant metastasis (χ2 =3.012,P =0.083).Logistic regression analysis revealed that lymph node metastasis alone was an independent predictive factor of HPV infection in NSCLC (OR =0.384,95%CI:0.153-0.967,P =0.042),and gender (OR =1.402,95%CI:0.522-3.769,P =0.503),smoking (OR =0.506,95%CI:0.194-1.322,P =0.506),histologic type (OR =0.393,95%CI:0.133-0.161,P =0.091)were not independent predictive factors of HPV infection. Conclusion The infection of HPV presents in part of Chinese NSCLC patients,and HPV infection may be connected with occurrence and development of lung cancer.

Objective To explore the effect of the simvastatin administration on the expression of connective tissue growth factor （CTGF） in fihrotic lungs of rats. Methods The cats were treated with single intratracheal instillation of bleomycin （BLM） or instillation of the same volume of normal saline （NS） as a control. The administration of simvastatin（20 mg/kg）began once a day immediately or 7 days later after intratracheal BLM instillation respectively with the same volume of NS was given as a vehicle control. The rats were killed on day 7,14 and 28 respectively. Pathological alteration of lung tissue was observed hy HE staining and Masson staining. Hydroxyproline（HYP）content in lung tissue was used to determine the severity of pulmonary fibrosis. The expression of CTGF in lung tissue was exanfined by immunohistochem- istry staining and photodeusitometry. Results Histopathological changes of pulmonary fibrosis emerged gradually after the instillation of BLM. The expression level of CTGF was increased in lungs of rats after intratracheal instillation of BLM, compared with the control. The administration of simvastatin immediately or 7 days after intratracheal instillation of BLM, attenuated the histopathological changes of bleomycin- induced puhnonary fibrosis and prevented the increased expression of CTGF in lung tissue on day 28. Conclusion The adntinistration of simvastatin, immediately or 7 days after intratracheal BLM instillation, prevented the up-regulation of CTGF in fibrotic lungs of rats, which ntight be one of the mechanisms of the anti-fihrosis of simvastatin in lungs.

Objective To investigate the application value of DWI based on biexponential signal decay model with extended b-fac-tor range in differential diagnosis of benign and malignant breast lesions.Methods A total of 57 patients with breast tumor under-went DWI based on the biexponential model with 12 b-factors (0,10,20,50,100,200,400,600,800,1000,1 200 and 1 500 s/mm2 ), including benign lesions in 1 9 patients (24 breast tumors,defined as benign group)and malignant ones in 38 (47 tumors,defined as malignant group ).The values of slow apparent diffusion coefficient,fast apparent diffusion coefficient and fraction of fast ADC of le-sions were measured at a workstation (Advantage Windows 4.5).Differences in these parameters between the benign and malignant groups were compared.Results The ADCslow,ADCfast and ffast were(1.434±0.291)×10 -3 mm2/s,(2.744±0.050)×10 -3 mm2/s and (0.677±0.130)% in benign group,and (0.614±0.196)×10 -3 mm2/s,(2.692±0.068)×10 -3 mm2/s and (0.446±0.112)% in malig-nant one,respectively.The statistical differences in ADCslow and ffast were found between two groups (P <0.05),whereas no difference in ADCfast was found.Conclusion Biexponential signal decay model of DWI with extended b-factor range can provide helpful tissue characterization parameters for the differential diagnosis of benign and malignant breast lesions.

【Objective】 To observe the effect of electroacupuncture(EA) onlearning and memoryin vascular dementia (VD) rats andto explore its possible therapeutic mechanism.【Methods】Fifty specific pathogenfree(SPF) adult rats were randomizedintofour groups.Except the 8 rats in the pseudo-operation group(group A),the other 42 rats were induced cerebral ischemia by four-vessel occlusion method.Then the model rats were randomized into model group (group B),EAgroup(group C) and nimotop group(group D).Groups Aand B were fed with the same forage and received no medication.Group Creceived EAonthe acupoints of Baihui,Geshu,Pishu and Shenshu,and EAwas set in continuous wave with the frequency being 150Hz,once per day and lasting 15 consecutive days.Group Dreceived nimotop 12mg/kg,qd,for 15 consecutive days.After 15-day treatment,the learning and memory abilities of the rats were observed by Morris water test,the plasma carbon monoxide(CO) level was detected by double-wavelength spectrophotometer,and brain nitric oxide(NO) content was examined byspectrophotometry-colorimetry.【Results】The model rats had obvious disorders of learningand memory,their escapelatency was prolonged,thetimes swimmingacross the platforminthe original quadrant did not differ fromthose inthe other three quadrants,and plasma COand cerebral NOlevels were obviouslyincreased.In EAgroup,escapelatency was shortened,thetimes swimmingacrossthe platform inthe original quadrant were more thanthose inthe other three quadrants,and plasma COand cerebral NOlevels were obviously decreased(P
