OBJECTIVE To investigate the expression profile of inflammation related genes in laryngeal squamous cell carcinoma by functional gene chip technique and to probe into the role of correlative genes in pathogenesis of the laryngeal squamous cell cancer and in tumor immunity. METHODS The total RNAs were respectively extracted from two pair samples of laryngeal tumor and the normal tissue around the tumor, and then were reversely transcribed to cDNAs, then synthesized to cRNAs. The cRNAs were labeled with the hybridization probes. The probes were then hybridized with four pieces of inflammation related genes chip. It was chemiluminescently detected and the acquired image was analyzed with special software. RESULTS Forty genes were differently expressed in inflammation related gene profile of laryngeal tumor, among which 22 genes were upregulated and 18 genes were down regulated. Thirteen genes were shown differential expression in both chips with 10 upregulated genes and 3 downregulated genes. CONCLUSION The differently expressed genes in inflammation related gene chips will provide clues and theoretical foundation for the investigation of the relationship between tumor and inflammation, and also the immune pathogenesis of laryngeal tumor. Furthermore CCL-7 may have an important role in the occurrence of laryngeal cancer, and the role of immunity of the pathogenesis of laryngeal tumor needs further studied.

OBJECTIVE To observe the effect of voriconazole on pulmonary fungals infection after renal transplantation.METHODS Nine cases of pulmanory fungals infection after renal transplantation were analyzed to evaluate the therapeutic effect of voriconazole.RESULTS Treated with voriconazole,seven in nine patients were cured,while the other two died.CONCLUSIONS For patients with pulmanory fungals infection after renal transplantation,the application of voriconazole can receive satisfactory effect.

Objective To explore the relationship between peripheral differential blood count and ATP value in Cell CD4 + T tested by ImmuKnow method in liver transplants. Methods In this study 49recipients after classic orthotopic liver transplantation (OLT) were enrolled. In a period from two weeks to two months after transplantation when all were free of glucocorticoid. Blood were sent for WBC differential samples count and ATP value in Cell-CD4 + T tested by ImmuKnow method via SPSS17. 0 software. Five more samples were selected randomly for duplicated testing of the indices in Week2, 3, 4,6 and 8 after the transplanting operation to further verify the relativity. Results White blood cell count has the highest relativity with ImmuKnow ATP value at 0. 821. The 5 recipients were repeatedly tested for ImmuKnow ATP values that were found positively correlated to cell count with a coefficient of over 0. 5. Conclusions The peripheral leukocyte count in early stage after liver transplantation is in positive correlation with ATP value in Cell CD4 + T, and the changes of numeration of leukocyte reflect changes of ATP value.
