Objective:To observe the effect of Pidotimod and Thalidomid to enhance the immune response and protective immunity induced by the epitope Vaccines From W2b2a of Toxoplasma gondii in mice.Methods:Mice were immunized intramuscularly with Pidotimod and pcDNA3-W2b2a,thalidomide and pcDNA3-W2b2a,respectively,then the immune response and the survival time of mouse attacked by Toxoplasma gondii were observed.Results:After the immunization,the level of IFN-γin sera of mice inculated with pcDNA3-W2b2a and Pidotimod,pcDNA3-W2b2a and Freund adjuvant,pcDNA3-W2b2a and Thalidomid were significantly higher than pcDNA3-W2b2a (all P<0.05).After the immunization,IgG,CD4+/CD8+T cell ratio ,proliferation of T cell induced by pcDNA3-W2b2a and Pidotimod,pcDNA3-W2b2a and Freund adjuvant were higher than pcDNA3-W2b2a,pcDNA3-W2b2a and thalidomid ( all P<0.05).After challenged with highly virulent tachyzoites,the mean survival time in immunized groups were significantly longer than control group (all P<0.05).Conclusion:Pidotimod ,Thalidomid adjuvant can increase protective immunity of epitope Vaccines From W2b2a of Toxoplasma gondii in mice.

Objective To investigate the expression of oncogene survivin,p53 in breast cancer and its ~prognostic significance. Methods The expression of survivin,p53 in breast cancer tissues of 80 cases were detected by immunohistochemistry S-P method, and its correlation with axillary lymph node metastasis and ~5-year disease free survival (DFS) was analysed.Results In breast cancer tissues,survivin gene positive ~expression rate was 68.75%(55/80), p53 gene positive expression rate was 46.25%(37/80), and both had a positive correlation with axillary lymph node metastasis but negative correlation to 5 years DFS(P0.05);survivin and p53 genes expression have positive corrlation(P

Objective To investigate the correlation between lumbar physiological curvature and Pfirrmann grading of lumbar intervertebral disc in young patients with lower lumbar pain.Methods 1 1 1 cases with lower lumbar pain were analyzed retrospectively by lumbar MRI examination.The MRI image was reviewed by two radiologists,and the degree of lumbar physiological curvature and lumbar disc degeneration were observed.Chi square test was applied to the statistical results.Results Final analysis was performed on 300 discs in 60 cases of patients with lumbar physiological curvature straightening.Among them,209 were grade Ⅰ-Ⅱ(70%),45 grade Ⅲ(15%),35 grade Ⅳ(11%)and 11 grade Ⅴ(4%)in Pfirrmann grading.In total of 255 discs of 51 cases with normal physiological curvature of the spine,there were 212 (83%)of Pfirrmann grade Ⅰ-Ⅱ,22 of grade Ⅲ(9%),19 of grade Ⅳ(7%)and 2 of grade Ⅴ(1 %).There was statistical difference between the lumbar physiological curvature straightening and the normal lumbar physiological curvature group (P< 0.05).The proportions of degeneration of Ⅰ-Ⅱ in the lumbar physiological curvature group was lower than that in normal lumbar curvature group,while the proportions of gradeⅢ,ⅣandⅤdegeneration in the lumbar physiological curvature group were higher than that in normal lumbar curvature group.Conclusion Stratification lumbar physiologic curvature is an important factor for lumbar disc degeneration and easy to cause Pfirrmann gradeⅣ-Ⅴdegeneration in young patients.
