ABSTRACT

Objective To explore the change of cellular immune function in renal cancer patients adopting thymopetidum (TP-5) combined with cytokine-induced killer cells (CIK) in peroperative period,and evaluate its curative effect.Methods Forty-one cases of Ⅰ-Ⅲ stage renal cancer patients adopting CIK treatment postoperatively were enrolled in this study for retrospective analysis.According to applicating condition of TP-5,the patients were divided into two groups:16 cases of combination group (TP-5+CIK) and 25 cases of CIK group.The patients in combination group were given TP-5 intramscular injection everyday from preoperative 1 d to postoperative 3 weeks,once a day.Peripheral blood mononuclear cell was collected in the patients of two groups,which was cultivated for 2 weeks and then transfused.Fasting peripheral blood 1 week (before collected peripheral blood mononuclear cell),3 weeks (before CIK retransfusion),4 weeks(after CIK retransfusion for 1 week) and 5 weeks(after CIK retransfusion for 2 weeks) after operation were examined,the peripheral blood T cell subgroups (CD3+,CD4+,CD8+) and nature killer cell (NK cell) levels were detected using flow cytometry.Results At 1 week and 3 weeks (before CIK) after operation,the levels of CD3+,CD4+/CD8+ and NK cell in combination group were significantly higher than those in CIK group:1 week after operation:0.542 ± 0.063 vs.0.491 ± 0.054,0.94 ± 0.09 vs.0.90 ± 0.12,0.247 ± 0.025 vs.0.223 ± 0.033;3weeks after operation:0.641 ±0.058 vs.0.587 ±0.062,1.71 ±0.13 vs.1.02 ±0.07,0.319 ±0.038 vs.0.264 ± 0.047).There were significantly differences (P< 0.05).At 4 weeks after operation,the levels of CD3+,CD4+/CD8+ and NK cell in combination group were significantly higher than those in CIK group:0.698 ± 0.041vs.0.649 ± 0.050,2.01 ± 0.11 vs.1.64 ± 0.09,0.331 ± 0.029 vs.0.289 ± 0.034.There were significantly differences (P < 0.05).At 5 weeks after operation,the levels of CD3+,CD4+/CD8+ and NK cell in two grotups were no significant difference (P > 0.05).At 4 and 5 weeks after operation,the levels of CD3+,CD4+/CD8+ and NK cell in two groups were significantly higher than those of 3 weeks after operation (P < 0.05).None of patients occurred acratia,hyperpyrexia,shivering and so on.Conclusions The application of TP-5 treatment in peroperative period can promote the recovery of cellular immune function,which has synergistic effect with CIK.The value of TP-5 is worthy of promotion.

ABSTRACT

With the aggravation of enviromental pollution, a quickly, sensitive, inexpensive monitoring means should be developed to protect water resources. Luminescent bacteria as biosensor have the advantages mentioned above. During past two decades, luminescent bacteria toxicity test was used widely in comprehensive toxicity evaluation, screening, monitoring and specific pollutants detection in water, the recent progress in this field was reviewed in this paper.
