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 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.

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 (P<0.01). Conclusions The discharge readiness of children with obstructive sleep apnea-hypopnea syndrome during day surgery was at the upper-middle level, but their personal status was not good. Medical and nursing staff should pay attention to health guidance for parents of children with disease-related knowledge, do a good job of interpretation before discharge, help parents increase their confidence in caring for children after discharge, improve the level of preparation for discharge, and ensure the safety of children after discharge.
