Methods: Thirty-one patients with malignant tumor after radiochemotherapy were treated with CIK cells. Before and after CIK cells being transfused back, the immunity indexes of the peripheral blood of these cases were detected and the changes of life quality of these cases were compared. Results: After radiochemotherapy, the percentage of CD3+, CD4+ cells declined, the percentage of CD8+ cells rose; the ratio of CD4+/CD8+ declined, and the percentage of CD16+, CD56+ cells declined. As all the above indexes compared with that of normal people, the difference was significant (P < 0.05). After CIK cells therapy, the above indexes improved (P < 0.05). Life quality improved significantly after CIK cells therapy (P < 0.05). Conclusion: Radiochemotherapy can inhibit the immunity in patients with malignant tumor. CIK cells therapy is safe and effective. It may improve the recent immunity and life quality of the patients, which suggesting that it may be an alternative maintenance treatment for patients with malignant tumor after radiochemotherapy.展开更多

Two soapstone blocks were placed outdoors under tropical environmental conditions for 12 months. A total of 9 filamentous fungal populations were identified on their surfaces, namely Acremomium （cf.） alternatum, Alternaria alternata, Aspergillusfumigatus, Calcarisporium （cf.） arbuscula, Cladosporium cladosporioides, Curvularia lunata, Epicoccum nigrum, Fusarium equiseti and Penicillium citrinum. The gamma radiation assay was then carried out as a test of biocidal action by exposing all fungal populations to the ionizing radiation. The results showed that only the C. cladosporioides species was resistant to this biocidal agent, since it was able to increase its population post exposure. Scanning electron microscopy images identified the microbial colonization on the soapstone blocks and the stone elementar composition was analyzed by energy dispersive X-ray spectrometry. After treatment, there was no structural and aesthetic alteration in the soapstone samples, and evidencing that gamma radiation can be used as a biocidal agent. However, the resistance of the black fungal population indicates caution in the choice of gamma irradiation as biocidal treatment.展开更多
