To study the B cell linear epitopes of rabies virus CVS-11 nucleoprotein, peptides were synthesized according to the amino acid sequences of B cell linear epitopes. Linear epitopes predicted by bioinformatics analysis were evaluated with immunological techniques. Indirect enzyme-linked immunosorbent assay showed that titers of antibodies to peptides (355-369 and 385-400 residues of rabies virus CVS-11 nucleoprotein) were above 1:12 800 in mouse sera. The antibodies recognized denatured rabies virus CVS-11 nucleoprotein in Western blot analysis. Purified anti-peptide antibodies recognized natural rabies virus CVS-11 nucleoprotein in BHK-21 cells in indirect fluorescent antibody test. The 355-369 and 385-400 residues of rabies virus CVS-11 nucleoprotein were validated as B cell linear epitopes.

Objective: To analyze associations of MRI-lesions and clinical features with disability in patients with multiple sclerosis (MS) in Shanghai, China. Methods: We studied patients with MS, identified from a survey in Shanghai, whose sites of lesions in the CNS was based on the MRI examinations. Associations between MRI-lesions, various clinical variables and the severity of disability were analyzed with univariate and multivariate logistic regression analysis. Results: There were 210 patients in this study. The disability of the patients with lesions confined to the spinal cord was significantly more severe than those with lesions in the brain (p < 0.008). Current age (OR: 1.041, 95% CI: 1.007~1.077), MS duration (OR: 1.082, 95% CI: 1.011~1.159) and MRI-lesions in the spinal cord (OR: 2.441, 95% CI: 1.039~5.737) were significantly associated with severity of disability on multivariate logistic regression analysis. Conclusion: MRI-lesions in the spinal cord, older age, a longer MS duration were significantly associated with a more severe disability in this MS study in Shanghai China.

Objective:To explore the independent prognostic factors of primary osteosarcoma patients under 20 years old after radical surgery, so as to predict the prognosis and survival of patients.Methods:The clinicopathological data of 1 339 patients with primary osteosarcoma diagnosed and registered in the National Cancer Institute Surveillance, epidemiology and outcome database (SEER) from 1984 to 2014 were retrospectively analyzed. Kaplan Meier method was used to calculate the survival rate of patients. Log rank test was used to evaluate the survival difference. Cox multivariate analysis was used to determine the independent prognostic factors of osteosarcoma after radical surgery factor.Results:The results of primary osteosarcoma patients undergoing radical surgery found that 34 cases (2.54%) aged 0-5 years old, 236 cases (17.63%) aged 6-10 years old, and 600 cases (44.81%) aged 11-15 years old and 469 cases (35.02%) aged 16-20 years old. The median survival time was 68 months. Among them, 757(56.53%) were male and 582(43.47%) were female. Among the 1 339 cases, 986 were white (73.64%), followed by black 230(17.18%), and 123 other races (9.18%). Multivariate analysis revealed that males ( HR=1.242; 95% CI:1.024-1.505), axial osteosarcoma ( HR=1.589; 95% CI:1.179-2.166), and regional invasion of osteosarcoma ( HR=1.470; 95% CI:1.156-1.870), distant metastasis ( HR=3.536; 95% CI:2.725-4.589) were independent risk factors for overall survival. Other types of osteosarcoma ( HR=0.471; 95% CI:0.285-0.779) were independent protective factors for overall survival. Conclusions:Based on the SEER database, this study identified independent prognostic factors for patients with primary osteosarcoma under the age of 20 who underwent radical surgery, which will help clinicians formulate individualized medical strategies and predict patients′ prognosis.

Objective To assess the applicability of the Modification of Diet in Renal Disease (MDRD)formula to kidney function impaired Chinese diabetic patients.Methods Glomerular filtration rates(GFRs)in 463 Chinese diabetic patients(219 female,244 male,aged 14 to 88)were estimated by measuring ~(99m)Tc-DTPA clearance and with equations based on serum creatinine(Scr)and cystatin C(Cys C)concentrations.GFRs derived from various equations were compared with the ~(99m)Tc-DTPA clearance GFRs and their relative accuracies were assessed with ROC analysis.All the Scr measurements were performed with both the Roche enzymatic assay and the Beckman LX20 kinetic alkaline picrate assay,and Cys C with immunonephelometric and immunoturbidimetric assays.Results The reciprocals of Cys C and Scr were linearly correlated with ~(99m)Tc-DTPA clearance GFRs(r=0.830 and 0.690,repectively).The correlation of GFR with Scr could be expressed by an adjusted MDRD equation:GFR [ ml?(min?1.73 m~2)~(-1)]=175?(Scr)~(-1.154)?(age)~(-0.203)?0.742(female)?0.827,where 0.827 was a coefficient for Chinese.The adjusted equation showed a better accuracy than the MDRD equation(areas under the ROC curve 0.818 vs 0.644).The adjusted equation was also more accurate than equations obtained in previous Chinese studies.GFRs were also estimated by using Cys(in mg/L)with the following equation:GFR [ ml?(min?1.73 m~2)~(-1)] = 63.24?(Cys C)~(-0.3378).The accuracy of the Cys equation was similar to the Scr equation,or better in patients aged 60 and above.The Roche enzymatic results which were traceable to the isotope dilution mass spectrometry(IDMS)methods were significantly lower than Beckman LX20 results,but the results were closely correlated with each other(Y = 0.94X-0.02).When non-traceable Scr results were used,the coefficient needed to be adjusted.Conclusions GFRs can be estimated with equations based on either Scr or Cys C.GFR estimation should use standardized Scr results and take into account ethnic effects.
