Objective To acquire NF-?B p65 TAD(transcription activation domain) and construct its eukaryotic expression vector and express it in endothelial cells.Methods Human umbilical vein endothelial cells(HUVECs) were cultured and total RNA was extracted.The p65 TAD gene was amplified by RT-PCR.After sequencing,the p65 TAD gene was inserted into the eukaryotic expression vector pEGFP-N1 with the green fluorescence protein,named pEGFP-N1-p65 TAD.pEGFP-N1-p65 TAD was transfected into HUVECs and its expression was observed under fluorescence microscope and analyzed by Western blotting.Results p65 TAD(288-548) was cloned successfully.The constructed plasmid including p65 TAD gene was identical to the designed.p65 TAD gene was expressed successfully in HUVECs.Conclusion The construction of eukaryotic expression vector including p65 TAD gene and its expression in HUVECs are very successful.

Objective To compare the diagnostic value of the Standardized Bedside Swallowing Assessment (SSA)and the Scottish Intercollegiate Guidelines(SIC)for bedside dysphagia screening of patients after acute cerebral infarction(ACI). Methods Eighty-six ACI patients within 24 h of stroke onset were enrolled in the study.Within 48 h after hospitalization,swallowing function assessments and dysphagia screenings were carried out with the SSA and SIG,as well as video fluroseopic swallowing studies(VFSSs).The SSA and SIG assessments generated sensitivities,specificities,positive predict values(PPVs),negative predict values(NPVs),positive likelihood ratios (PLRs)and negative likelihood ratios(NLRs).These were compared with the VFSS results. Results The SSA showed a sensitivity of 89.1%,specificity of 75%,PPV of 0.804,NPV of 0.833,PLR of 3.56,NLR of 0.15,and Kappa of 0.648 compared to the VFSS results.The SIG showed a sensitivity of 60.9%,specificity of 82.5%,PPV of 0.800,NPV of 0.647,PLR of 3.44,NLR of 0.47 and Kappa of 0.425 compared to the VFSS.The sensitivity of of the SIG.Both assessments correlated well with the VFSS results. Conclusions Both the SSA and the SIG are elfective in dysphagia screening.The SSA is more sensitive than the SIG and is more suitable for early screening.The SIG is helpful in guiding dysphagia management and evaluating curative effects.

Background Experimental autoimmune uveoretinitis(EAU)is proved to be an organ-specific,T lymphocyte-mediated autoimmune and self-limited disease.Research showed that CD4+CD25+T cell may play important regulation on the course of events,but its mechanism is pending for further study. Objective Present study was to investigate the potential role of CD4+CD25+T cell in the pathogenesis of EAU. Methods Retinal Santigen(S-Ag)was isolated from bovine retinas according tO the procedure as Caspi's previously describe.0.1 ml Santigen(50μg)emulsified with complete Freund'S adjuvant was injected on footpad of 24 inbred adult female Lewis rats aged six to eight-week-old to induce EAU,and 4 normal Lewis rats were as normal control group.Slim-lamp examination was performed to observe the ocular manifestation.Retinal section was prepared in 7,12,15,21 days aher injection for the pathological examination.The pathological grading was on the lnoki'S method.The retinas,inguinal nodes and spleens of rats were obtained in 7,12,15,21 days after injection and the cellular suspension was prepared.Expression of CD4+CD25+T cells on cellular suspension was assayed using flow eytometry.This study complied with the Standard of Association for Research in Vision and Ophthalmology. ResuRs The obvious inflammatory response of the anterior segment was found in S-Ag injected eyes from 7 days through 21 days.The most serious inflammation was found in 12-15 days under the slim-lamp.The hemotoxylin and eosin staining showed the higher pathological grading from 12 to 15 days after injection,showing significant difference in comparison with 7 days and 14 days(P=0.000).In EAU model rats,expressions of CD4+CD25+T cells was significantly increased in retinas, inguinal nodes and spleens in 15 days after injection,showing evidently differences in comparison with control rats(P=0.000). Conclusion The expression level of CD4+CD25+T cells in inflammatory tissue is associated with the inflammation procedure in EAU model rats.This study indicates that CD4+CD25+T cells may play a role in the development of EAU.
