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 make a summary of radiation-induced changes in ocular lens and retinal lesions based on dynamic follow-up of a patient exposed to a radiation exposure from 192 Ir source accident,in order to provide the information and experience for the clinical diagnosis and treatment of such injury in emergency of a nuclear or radiation accident.Methods The examination methods included eye lens and visual acuity,slit-lamp examination,fundus examination,automated perimetry,optical coherence tomography (OCT) examination,fundus photography,and fundus fluorescein angiography (FFA).The patient was followed-up for 20 months.Comparative analyses were made of the follow-up results.Results One month after 192Ir radiation exposure,the visual acuities in both eyes were 1.0.Mild age-related opacities were observed in peripheral cortex,but the fundus looked normal.Twenty months later,the patient was followed-up.The visual acuities reduced to about 0.6,evident powder-and punctuate-like opacities could be observed in the cortex of the right lens,and mild turbid foci in the posterior polar and capsule.Multiple scotomata appeared in the superior temporal and inferior nasal in the right eye.The macular fovea thickness was not changed significantly in the right eye.Examination with fundus photography demonstrated mild optical nerve atrophy,drusens,and pale optic discs,while FFA examination showed punctuate or flocculent leakages in both eyes.Conclusions The lens opacity could be induced or accelerated by radiation exposure.In addition to the posterior capsule and pole cataracts,punctuate opacity within cortical layer may also occur.It also suggests that cataract and fundus injuries may occur later during long-term follow-up,even though the eyes may look normal during early examination after the patient exposed to the radiation.

A dispersive solid phase extraction method combined with reversed phase liquid chromatography was investigated for the determination of benzo ( a ) pyrene ( BaP ) residues in edible oil and oil products. The developed “one-step” sample preparation method integrated with the adsorbent activation, sample extraction and sample cleaning. Using Alumia-N as the adsorbent, good cleaning effect and high recovery ranging from 81. 5% -97. 5% was achieved. In addition, coupled with fluorescence detector (FLD), high sensitivity was obtained with LOD of 1. 0 μg/kg (S/N=3). Furthermore, SPSS was used to design orthogonal optimization experiments and establish the optimal condition. Under the optimized condition, the standard calibration curve was linear over the concentration range of 0. 5-10. 0μg/L, with the regression efficiency (R2) of 0. 9997. The relative standard deviation (RSD) of peak area was between 2. 6%-4. 9%, showing good repeatability and the reliability.

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 observe the changes of the heart rate turbulence(HRT)in patients with isolated systolic hypertension(ISH).Methods 85 patients with ISH,80 patients with common hypertension and 58 control subjects were investigated.Turbulence onset(TO)and turbulence slope(TS)were recorded of 24 hours dynamic electrocardiogram.Results The difference of HRT in the three groups was significant(P＜0.01).The values of TO and TS was significantly higher in common hypertension group and ISH group than in control group(P＜0.05);TS was significantly lower in ISH group than in common hypertension group(P＜0.05),but the difference of TO between ISH group with common hypertension group was not obvious.Conclusion The HRT in patients with primary hypertension is significantly lower,which is more significant in patients with ISH than in patients with common hypertension.It suggests that the cardiac autonomic nerves dysfunction perhaps has an important influence on development of hypertension and its prognosis.

Objective To investigate a dose response curve based on a genetic workstation with automatic analysis system of dicentric chromosome assay (DCA) for establishing a high speed dose estimation method.Methods Peripheral blood from three healthy volunteers was irradiated in vitro using 60Co γ-rays,and then lymphocytes were cultured and fixed on slides using the standard protocol for DCA.Dicentric chromosome in metaphase cells was analyzed automatically with the genetic workstation and confirmed manually,and the dose response curve of automated dicentric chromosome was fitted.Dicentric chromosome of another peripheral blood sample irradiated with different doses was manually analyzed to verify the accuracy of the above automated DCA.Results The yield of automated DCA was well fitted by an equation Y =0.018 06D2 + 0.012 79D + 0.000 489 1 with a correlation coefficient R2 =0.961.The biological dose of radiation could be accurately estimated by this dose response curve within a few minutes.Conclusions We had successfully established a new dosimetry method by analyzing dicentric chromesome automatically,which can save a lot of manual analysis time and hence has important significance for emergency rescue in nuclear accidents.

Objective To investigate the application value of clinical typing in the treatment of BuddChiari syndrome (BCS).Methods The retrospective corss-sectional study was adopted.The clinical data of 95 patients with BCS who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2012 to September 2015 were collected.Based on patients' compensation and clinical symptoms,3 clinical typing and 8 subtypes of BCS were proposed,and each subtype was treated with corresponding strategies.Observation indices included (1) the clinical typing of BCS,(2) selection of treatment,(3) treatment effect,(4) follow-up situations.Follow-up using telephone interview and outpatient examination was performed once within 3 months after the first treatment and then once every 6 months up to December 2015 or death,loss to follow-up and experienced decompensation.During follow-up,color Doppler ultrasound and blood bio-chemistry test were performed regularly,and CT angiography was also conducted when necessary.Count data were presented as the case or percentage.The survival rate was calculated using Kaplan-Meier method and the survival curve was drawn.Results (1) BCS clinical typing of 95 patients:4 were detected in type Ⅰ (3 in type Ⅰ a and 1 in type Ⅰ b),7 in typeⅡ (4 in type Ⅱa and 3 in type Ⅱb),and 84 in type Ⅲ(43 in type Ⅲa,4 in type Ⅲb,32 in type Ⅲc,and 5 in type Ⅲd).(2) Selection of treatment in 95 patients:① among the 3 patients with type Ⅰ a,2 of them received inferior vena cava balloon angioplasty while 1 patient had to give up the operation due to failure in opening the occlusion.This patient underwent close observation and follow-up afterwards.② The patient with type Ⅰ b underwent cavity-antrum artificial blood vessel bypass operation due to failure in opening the occlusion.③Among the 4 patients with type Ⅱ a,one of them underwent hepatic vein balloon angioplasty.The other 3 patients underwent close observation and follow-up because of failure in intervention therapy,such as segmental occlusion of hepatic vein or difficulty in finding the hepatic vein.④ Among the 3 patients with type Ⅱ b,due to the history of upper gastrointestinal bleeding,2 patients received modified spleen-lung fixation and intestine-cavity blood vessels bypass,respectively,and 1 patient received intestine-cavity artificial blood vessels bypass due to severe peritoneal effusion.⑤ Among the 43 patients with type Ⅲ a,35 patients underwent inferior vena cava balloon angioplasty due to failure in hepatic vein intervention therapy (6 of them received firstly thrombolysis treatment due to combined thrombosis.Four patients received inferior vena cava and hepatic vein balloon angioplasties.Another 4 patients received close observation and follow-up due to failure in both inferior vena cava and hepatic vein intervention therapy.⑥Among the 4 patients with type Ⅲ b,2 underwent inferior vena cava balloon angioplasty and intestine-cavity artificial blood vessel bypass.The other 2 patients only received modified spleen-lung fixation because of failure in inferior vena cava intervention therapy.⑦ Among the 32 patients with type Ⅲ c,3 underwent inferior vena cava and hepatic vein balloon angioplasties,and 27 patients underwent only inferior vena cava balloon angioplasty due to failure in hepatic vein intervention therapy (7 of them received balloon angioplasty following thrombolysis treatment due to combined thrombosis).On account of failure in both inferior vena cava and hepatic vein intervention therapy,2 patients underwent resection of lesion membranes and cavity-antrum artificial blood vessel bypass,respectively.⑧ Among the 5 patients with type Ⅲ d,1 underwent inferior vena cava balloon angioplasty and intestine-cavity artificial blood vessel bypass,and 4 underwent only modified spleen-lung fixation due to failure ininferior vena cava intervention therapy.(3) Treatment efficacy:of 95 patients,8 received followup observation,and 87 patients recovered to varied extent after interventional therapies and operations,with symptomatic relief of leg edema,ulcer,peritoneal effusion and esophageal varicosity.Eighty-seven patients went through the perioperative period safely,and no death occurred.The incidence of postoperative complications was 10.3％ (9/87).The complications mainly include venous thrombosis in lower limbs during catheter-directed thrombolysis therapy,pleural effusion,pneumatosis,and peritoneal effusion after surgery,all of which were cured after symptomatic treatment.(4) Follow-up results:87 were followed up for 3-42 months with an average time of 19 months.During the follow-up,5 patients (1 in type Ⅰ a and 4 in type Ⅲa) received recanalization surgery because of the reocclusion after the inferior vena cava balloon angioplasty,and no decompensation occurred.However,decompensation was found in 11 patients (disease progression in 4 patients and symptom relapse in 7 patients).The survival rates of patients without decompensation at 0.5,1.0,2.0 and 3.0 years after the first treatment were 96.5％,95.0％,83.4％ and 80.5％,respectively.Conclusion According to patients' compensation and clinical symptoms,clinical typing of BCS and treatment strategiesis are determined,and it will provide a satisfactory clinical efficacy.

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 provide nutritional supportive scheme for patients with radiation injury through the treatment of the one exposed to Nanjing 192Ir source accident.Methods The reasonable nutrition treatment scheme was made on the basis of dietary survey and nutritional index monitoring during clinical stages of the patient,including body weight,body mass index(BMI),biochemical indexes,electrolyte,etc.,as well as metabolic cart determination of resting energy expenditure (REE).Results Patient on admission (days 5 post-irradiated) weighing 42.5 kg,172 days after the first irradiated (the first skin grafting) fell to a minimum of 36 kg,then gradually rise,hen rose back to normal range on days 383 before discharge.Normal admission hemoglobin was 135 g/L,172 d after irradiated to a minimum of 54 g/L,normal discharge;when lymphocytes admission low as 0.5 × 109/L,58 days back to normal after exposure,172 days after irradiated down to 0.4 × 109/L.Serum albumin was normal admission 41.2 g/L,172 days after irradiated down to 25.3 g/L.The normal level of serum prealbumin was 0.22 g/L,248 days to a minimum of 0.04 g/L,the basic return to normal at discharge was 0.17 g/L.Admission normal liver function,bilirubin index slightly higher,the all in one parenteral nutrition after about 2.5 months later,bilirubin and liver function indicators were gradually increased,the adjusted treatment and nutrition liver and gallbladder and other gradually returned to normal after treatment.REE and the body weight were determined by metabolic cart on days 294,308 and 342 for the energy requirements.Conclusions For patient with radiation injury,appropriate nutrition therapy is a key method for the clinical treatment and rehabilitation,which can maintain the nutritional status of patients and improve clinical treatment.
