International community-based rehabilitation(CBR) has adjusted the concept to meet the demands of disabled during30-years development. As the latest concept, 2010 CBR Guidelines guides CBR work in countries around the world. Chinese CBR work isfar away from the standards of international CBR concept, so Chinese CBR has to learn international CBR concept and consider Chinese situationto develop CBR with Chinese characteristics. The paper introduces the latest development and contents of international CBR, elaborateshow right and participation reflects in CBR for the disabled in China. On the basis, taking the example of Yuexi program of HandicapInternational, the paper introduces how to integrate resource, promote CBR and social inclusion of the disabled.

Objective: To explore the diagnostic value of dual-source CT energy parameters in qualitative diagnosis of metastatic cervical lymph nodes after surgical resection of thyroid papillary carcinoma (PTC). Methods Totally 30 postoperative PTC patients with 74 enlarged cervical lymph nodes were enrolled, including 49 metastatic lymph nodes (metastatic group) and 25 non metastasis lymph nodes (non-metastatic group). In addition, 30 cases with benign enlarged cervical lymph nodes were taken as benign group. All subjects underwent dual-source CT scanning. The iodine concentration value of nonenhanced phase (ICNP), arterial phase (ICAP) and venous phase (ICVP), normalized iodine concentration (NIC) and slope of energy spectrum curve (K) were detected and compared among 3 groups. Results: There were significant differences in ICNP, ICAP, ICVP, NIC and K among 3 groups (all P<0.05). ICNP in metastatic group was lower than that in non-metastatic group and benign group (both P<0.05), while ICAP, NIC and K were higher than those in non-metastatic group and benign group (all P<0.05). No significant difference was found in ICNP, ICAP, ICVP, NIC and K between non-metastatic group nor benign hyperplasia group (all P>0.05). Conclusion: Dual-source CT energy parameters can be used to qualitatively diagnose cervical enlarged lymph nodes after surgical resection of PTC.

Objective To examine the levels of serum adipunectin (ADPN)in patients with end-stage renal disease (ESRD), and identify the relationship between serum ADPN and tumor necrosis factor (TNF)-α, high sensitivity C-reactive protein(hs-CRP) and renal function. Methods Sixty ESRD patients and twenty normal healthy persons were involved in this study. The patients were divided into three groups: patients with chronic renal failure (CRF, 18 cases), patients with hemodialysis (HD,22 cases) and patients with peritoneal dialysis (PD,20 cases). The levels of serum ADPN, TNF-α and hs-CRP were detected by means of ELISA. Differences in continuous variables be-tween the three groups were evaluated. Results The levels of serum ADPN, TNF-α and hs-CRP in CRF, HD and PD patients were signifi-cantly higher than those in control group ( P<0.01 ). Serum ADPN levels in ESRD patients were positive related to serum TNF-α( r≥0.478, P<0.01 ), and negative related to GFR ( r≥-0.582, P<0.01 ). Conclusion The level of serum ADPN was markedly in-creased in patients with ESRD, and correlated with serum TNF-α level and.renal function.

Objective To investigate the levels of serum interleukin(IL)-18 in patients with chronic renal failure (CRF)and its relationship with relevant indexes. Methods Sixty patients with CRF were divided into three groups: patients with CRF (CRF group, n = 18) ,patients with bemedialysis (HD group, n = 22) and patients with peritoneal dialysis (PD group,n = 20). 20 healthy subjects were taken as controls. The levels of serum IL-18, tumor necrosis factor (TNF)-α and high sensitivity C-reactive protein (hs-CRP) were detected by means of ELISA. Serum albumin (ALB) ,total cholesterol (TC) ,triglyceride (TG) and serum creatinine (SCr) levels were detected by con-ventional means. The GFR was measured by using the abbreviated Modification of Diet in Renal Disease study (MDRD) equation. Differences in continuous variables between the three groups were evaluated. Results The lev-els of serum IL-18 were significantly increased in CRF[(497.7 ± 120.7) ng/L], HD[(538.1 ± 113.2) ng/L] and PD[(565.7 ± 122.1) ng/L] patients than those in healthy subjects[(163.9±42.2) ng/L] (P <0.01). Further-more,serum IL-18 levels in HD patients were higher than these in CRF patients (P <0.05). Serum IL-18 levels in CRF were positively related to serum TNF-α,hs-CRP and SCr(r =0. 636,0.436,0.367,P <0.01) ,and negatively related to GFR(r = -0.515 ,P <0.05). Conclusion The levels of serum IL-18 are markedly increased in patients with CRF,HD and PD,and related to the levels of TNF-α,hs-CRP and GFR,so IL-18 might be an important marker of sub-clinical inflammation in patients with chronic renal failure.

Objective To make a rapid dose estimation for a patient exposed locally to high dose radiation exposure in early stage of 5.7 192Ir source accident in Nanjing.Methods Based on source parameters,exposure pattern,and time duration,the doses were estimated using MCNP simulations with the aid of the proper East Asia adult male voxel phantom and main physiological parameters of the exposed patient.Result Absorbed doses to 16 organs or tissues were estimated to be in the range 0.03 to 9.16 Gy.Also,the iso-dose curves for the skin of legs showed clearly the dose difference between right and left legs.Absorbed doses to patient's testicles and prostrate,about 9.16 Gy,were higher than those to other organs or tissues.The skin of both legs was exposed locally to high dose radiation exposure,for which the estimated doses were in agreement with the results obtained from infrared thermal imaging.Conclusions Monte Carlo simulation technique and common software can be used for dose estimation in early stage of radiation accidents effectively with integrating proper models.

Objective To use three different methods in attempt to estimate the biological dose of the patient partially exposed to 192Ir source at5.7 accident in Nanjing,so as to provide dosimetric information for clinical remedy of exposed patients in the emergency of a nuclear accident.Methods Peripheral blood samples were collected on days 5 after exposure.The biological dose was estimated by the yields of dicentrics plus rings ( dic + r),cytokinesis-block micronuclei (CBMN) assay and nucleoplasmic bridge plus FHC (NPB + FHC).The homogeneity of radiation exposure was examined by Poisson distribution of dicentrics.Results By using three different methods,the whole body equivalent dose was dic + r estimated to be 1.51 Gy (95％ CI 1.40-1.61),1.47 Gy (95％ CI 1.36-1.60) by CBMN and 1.30 Gy (95％ CI 1.00-1.60) by NPB + FHC,respectively.A non-poisson distribution was also detected,suggesting partial body radiation exposure.Conclusions The estimated whole body equivalent dose ot a non-uniform radiation exposure was consistent with clinical diagnosis,suggesting that the yields ofdic + r,CBMN,as well as NPB + FHC,are efficient approaches to the estimation of biological doses.

Objective To explore the natural attenuation pattern of three biological dose estimation indexes in vivo by investigating the effect on biological dosimetry of peripheral blood sampling at different time points from the victim partially exposed to 192Ir radiation source at5.7 accident in Nanjing.Methods Peripheral blood of the patient was collected on days 5,40 and 280 after exposure,respectively.The yields of dicentrics plus rings chromosomes (dic + r),cytokinesis-block micronuclei (CBMN) and nucleoplasmic bridge + fusion + horse shoe + circular(NPB + FHC) were analyzed.The dynamic reduction and dose estimation were both observed using the biomarkers mentioned above after exposure.Results Compared to the estimates on days 5 after exposure,the dose values estimated on days 40 and 280 decreased by 34％ and 49％ fordic + r method,48％ and 79％ for the CBMN assay,and 48％ and 75％ for NPN + FHC method,respectively.Conclusions Three biological dose estimation indexes show a progressive decrease in vivo,with the half-life of dic + r/cell being 40 days.The doses estimated using these three indexes on days 40 after exposure showed a relative deviation more than 20％ compared with those on days 5 after exposure.

OBJECTIVE: To explore. HRCT and MRI three-dimensional fast imaging employing steady state ac-quisition(3D-FIESTA) imaging features and clinical characteristics of bilateral large vestibular aqueduct syndrome(LVAS). METHOD: The imaging and clinical features of 14 cases of bilateral LVAS identified over a 5-year periodwere retrospectively analyzed. All patients underwent HRCT and MRI 3D-FIESTA scanning of head and neck;MRI three dimensional reconstructions of internal acoustical meatus were also completed at the same time. RESULT: Audiogram showed mild to moderate hearing loss and was progressive. The cut-off values for the coronal midpointand operculum planes on the HRCT scan to diagnose an EVA were 1. 5 mm and 4. 3 mm respectively; the averagevalue was 2. 4 mm. VA expansion degree were not linked to the degree of hearing loss. MRI showed VA andlymph sac abnormalities. Concomitant image finding was cochlear hypoplasia. CONCLUSION HRCT and MRI 3D-FI-ESTA are important examinations for accurate diagnosis of LVAS. HRCT can acquire the specific size of reamedVA. MRI and 3D reconstructions of internal acoustical meatus can noninasive show more intuitive display ofLVAS and other inner ear malformations than HRCT.

Brain metastases are common in oncologic patients. Stereotactic radiosurgery (SRS) is an effective treatment for oligo brain metastases. However, SRS is not suitable for large metastatic lesions. Fractionated stereotactic radiation therapy (FSRT) is a new option for the treatment of brain metastases. It can deliver high doses of radiation to tumor while protecting the normal tissues and organs outside the irradiation field as much as possible and maintaining good local control rate of tumors. This article reviews the dose-response relationship and adverse reactions of FSRT with different fractionated dose schemes, and the progress of FSRT combined with targeted therapy and immunotherapy.
