Objective To explore the rehabilitation needs of people with disabilities and the related factors,so as to provide a scien-tific basis for the rehabilitation policy-making for people with disabilities. Methods From June,2014 to July,2015,based on the national special survey of basic services and needs of people with disabilities in Jiangsu,China,this paper clarified the factors related with the rehabilitation needs of the disabled into the individual characteristics, economic characteristics, environmental characteristics and so on by the de-scriptive statistics method. The Logit model was established to explore the factors related with rehabilitation needs. Results In Jiangsu,43% people with disabilities aged 16 and above had rehabilitation needs.Contingency table analysis and Chi square test showed that individual characteristics,economic characteristics and environmental character-istics had significant impact on the rehabilitation needs of the disabled.Multiple regression analysis showed that all the 18 variables were the significant related factors. Conclusion In order to meet the rehabilitation needs of the disabled, the refined and precise rehabilitation program should be designed in line with the different characteristics of the disabled.Through the effective docking of sup-plies and needs,we can provide accurate rehabilitation services for the disabled.

Objective To study the conventional MRI and dittusion weighted imaging(DWI) features of Japanese encephalitis(JE)in children.Methods Sixteen patients with JE were included. Conventional MRI and DWI sequences were performed in all patients.Seven patients received MRI within 10 days of onset and 9 after 10 days.The appearances on DWI and T_2 WI were recorded.The ADC values of lesions were calculated,and then were correlated with the corresponding time interval between onset of neurological symptoms and MRI scanning.Results The lesions of JE mainly showed long T_1 and long T_2 signal intensity on MRI.The thalami were the most frequently involved areas,and 15 out of 16 showed thalamic involvement and 6 patients only showed thalamic abnormalities without other lesions.Seven patients within 10 days of onset showed lesions with high signal intensity on both DWI and T_2WI,but whole or partial lesions showed clearer on DWI than on T_2WI,and 2 patients showed extra lesions that were invisible on T_2WI.As for the other 9 patients after 10 days of onset,the lesions showed clearer on T_2WI than on DWI. There was a direct correlations between thalamic ADC values and the disease duration (r=0.84,P

OBJECTIVEThe causes of chronic diarrhea in children are complex. At present, food allergy is generally viewed as an important cause of this disorder, and IgG-mediated delayed allergy plays a major role in this process. This study aimed to explore the link between food specific IgG and chronic diarrhea in children, as well as the value of food allergens-specific IgG antibody detection in the management of this disorder.

METHODSEighty-two children with chronic diarrhea and 30 healthy controls were enrolled. Serum levels of specific IgG antibody to 14 kinds of food were detected using ELISA. The results were classified into four grades: Grade 0 (negative), Grade 1 (mild allergy), Grade 2 (moderate allergy) and Grade 3 (severe allergy). The patients received a diet treatment based on the results of food specific IgG antibody detection. Children with negative IgG antibody were allowed to continue their current diet. In children with Grade 1 allergy, the food responsible for the IgG antibody positive test was given only at an interval of four days. In children with Grade 2 or 3, the offending food was eliminated from the diet.

RESULTSOf the 82 children with chronic diarrhea, 79 (96.2%) had increased specific IgG levels for one or more of the 14 foods tested compared to 8 (26.7%) of the controls (P <0.01). The majority of patients showed increased specific IgG levels for milk (68.3%) and egg (62.2%). A low proportion of patients (2.4%) was allergic to chicken, and no patient was allergic to pork. The symptoms were improved in 65 patients (79.3%) after 1 week to 3 months of diet treatment.

CONCLUSIONSFood allergy is one of major causes of chronic childhood diarrhea. Food specific IgG antibody detection may assist in the dietary management of this disorder.

UNLABELLEDTo identify differentially expressed genes between fetal mesenchymal stem cell (MSC) and adult MSC, especially specified genes expressed in fetal MSC, a cDNA subtractive library of fetal MSC was constructed using suppression subtractive hybridization (SSH) technique. At first, total RNA was isolated from fetal and adult MSC. Using SMART PCR synthesis method, single-strand and double-strand cDNAs were synthesized. After Rsa I digestion, fetal MSC cDNAs were divided into two groups and ligated to adaptor 1 and adaptor 2 respectively. Results showed that the amplified library contains 890 clones. Analysis of 890 clones with PCR demonstrated that 768 clones were positive. The positive rate is 86.3%. The size of inserted fragments in these positive clones was between 0.2 - 1 kb, with an average of 400 - 600 bp.

CONCLUSIONSSH is a convenient and effective method for screening differentially expressed genes. The constructed cDNA subtractive library of fetal MSC cDNA lays solid foundation for screening and cloning new and specific function related genes of fetal MSC.

OBJECTIVETo investigate the induction of apoptosis on human oral epidermoid carcinoma KB cells and multidrug resistant KBv200 cells by Matrine.

METHODSMTT assay was used to investigate the inhibition ability of Matrine on the cells in vitro. Transmission electron microscope was used to observe the ultrastructure feature of cells. after treated by Matrine. Acridine orange (AO)/Ethidium bromide (EB) fluorescent staining and flow cytometry were used to observe apoptosis induced by Matrine. Flow cytometry was applied to study the effects of the drug on cell cycles of the cells.

RESULTSWhen 0.50, 1.00, 1.50, 2.00 mg/ml of Matrine was used, the vital rates of KB and KBv200 cells were decreased according to Matrine's concentration. The IC50 concentrations of Matrine on KB and KBv200 cells were 1.35 mg/ml and 1.43 mg/ml individually. The results of AO/EB fluorescent staining and flow cytometry showed that Matrine could induce apoptosis of two kinds of cells. While observed by transmission electron microscope, there were more contraction of cells, condensation of nuclei, bubble of cytoplasm in both kinds of cells after treated by Matrine. Matrine could stop the growth of KB and KBv200 cells at S period and restrain mitosis of cells.

CONCLUSIONMatrine can inhibit the growth of KB and KBv200 cells by inducing apoptosis. The apoptosis effect is dose-dependent and it has certain relation to the blocking of S period cells.

OBJECTIVEUndried silver-hydroxyapatite-titania (Ag-nHA-nTiO2) nanoparticles slurry was used to make membrane with polyamide 66 (PA66) by co-polymerization method. The purpose of this study is to test the physical and chemical characteristics and antibacterial ability.

METHODSThe morphology, chemical components and structures of the membrane were characterized by atomic absorption spectrometer (AAS), X-ray diffraction (XRD), scanning electron microscope (SEM) and energy-dispersive X-ray analysis (EDX). Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), Porphyromonas gingivalis (P. gingivalis), Fusobacterium nucleatum (F. nucleatum) and Streptococcus mutans (S. mutans) were utilized to test the antibacterial effect.

RESULTSXRD results demonstrated that the membrane have characteristic diffraction peaks of pure hydroxyapatite (HA). A homogeneous distribution of the Ca, P, Ti and Ag element in the membrane was confirmed by EDX. Both surface and section showed porous structure which was confirmed by SEM and the average hole size was 20-30 microm. The bacteria assay reflected to the antibacterial effect, 50.10% of S. aureus and 56.31% of E. coli were killed. However, 91.84% of P. gingivalis, 90.64% of F. nucleatum and 90.49% of S. mutans were killed and pictures of SEM showed obviously fewer cells on the surface.

CONCLUSIONThe nanocomposite membrane could be one of the bioactive materials with antibacterial properties for oral guided bone regeneration technique.
