Objective To investigate the antitumor effect of specific cytotoxic T lymphocytes induced by renal cell carcinoma multiple antigen peptide dendritic cell (DC) vaccine in vitro. Methods Dendritic cells were induced by hGM-CSF,hIL-4 from blood.Peptide of renal cell carcinoma cell line (RCC786-0)was got by citrate-phosphate buffer elution.Peripheral blood mononuclear cell was cultured.Multiple antigen peptide DC cell vaccine was obtained by acid-eluted peptide pulsed DC.The tumor antigen specific CTL was generated from activated T cell by vaccine.Killing activity of the tumor antigen specific CTL was activated by vaccine. Results Antigen peptide DC cell vaccine could show a strong cytotoxic activity of CTLs(31.93±5.05%),which was much higher than control groups(5.88±2.26%,8.03±6.70%,9.70±2.09%,9.35±3.58%). Conclusion Renal cell carcinoma antigen peptide DC vaccine could show a high antitumor effect in vitro.

In the present study ,we aimed to observe the effect of curcumin on TSST-1-induced inflammatory cytokines in splenocytes of mouse and provide evidence for the further study on the effect of curcumin on inflammatory shock .Lactate de-hydrogenase (LDH) release assay was used to determine cytotoxicity of different doses of TSST-1 and curcumin .Inflammatory cytokines were determined by ELISA and flow cytometry .The doses of TSST-1 and curcumin we used in the present study did not cause significant cytotoxicity .TSST-1 induced higher level of IFN-γand IL-2 production but relatively lower level of TNF-α.The production of IL-1β,IL-6 and IL-12 was undetectable .TSST-1 induced Th1 cytokines (IFN-γand IL-2) were not IL-12-dependent which was different from LPS-induced IFN-γ.Curcumin significantly reduced IFN-γand TNF-αproduction at the concentration of 15 umol/L (P<0 .05) ,but had no effect on IL-2 production (P>0 .05) .It’s suggested that curcumin could significantly inhibit the production of IFN-γand TNF-αby splenocytes induced by TSST-1 ,but could not affect the prolifera-tion of T cells .

Objective:
To understand the readiness for hospital discharge of the day surgery patients of obstructive sleep apnea-hypopnea syndrome and analyze its influencing factors.
Methods:
A total of 129 children with obstructive sleep apnea-hypopnea syndrome during the day surgery were investigated with a general data questionnaire and an adapted discharge preparation metric.
Results:
The total score of the readiness for hospital discharge was 166.38±30.93. The scores of discharge in all dimensions from high to low were adaptive ability 8.35±1.80, expected support 8.17±1.70, knowledge status 7.35±2.10, and personal status 7.10±1.43. Multiple linear regression results showed that the difficulty of caring for children from parents had a significant effect on the readiness of children with obstructive sleep apnea hypopnea syndrome during day surgery (
