OBJECTIVE:
This study was to investigate the expression and significance of Integrins subunits in laryngeal squamous cell carcinoma (LSCC).
METHOD:
The expression of Integrins subunits was detected by cDNA microarray in 4 cases of primary LSCC tissues and corresponding adjacent normal tissues. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) were used to identify the different expression of Integrins subunits in 24 cases of primary LSCC tissues and corresponding adjacent normal tissues.
RESULT:
A cDNA microarray analysis revealed significant changes in the expression of Integrins subunits, with IntegrinalphaV, Integrinbeta8 being up-regulated and Integrinalpha8 being down-regulated. The result of RT-PCR was consistent with that of cDNA microarray. The mRNA levels of IntegrinalphaV and Integrinbeta8 were significantly higher in LSCC tissues than that in corresponding adjacent normal tissues (1.0131 +/- 0.4780 vs 0.7591 +/- 0.4678 for IntegrinalphaV, P<0.05, 1.7362 +/- 1.3849 vs 1.2267 +/- 0.9363 for Integrinbeta8, P<0.05). The mRNA levels of Integrinalpha8 were significantly lower in LSCC tissues than that in corresponding adjacent normal tissues (0.2646 +/- 0.2622 vs 0.5457 +/- 0.3827, P<0.05).
CONCLUSION
The expression of IntegrinalphaV, Integrinbeta8, Integrinalpha8 were significantly up-regulated or down-regulated in laryngeal squamous cell carcinoma, which may relate to tumorigenesis and development of laryngeal squamous cell carcinoma.

OBJECTIVE:
Our previous study revealed many genes differentially expressed in human laryngeal squamous cell carcinoma tissues (LSCC) and related adjacent normal tissues. We verificated the differentiated expressions of target genes, possibly related to LSCC. And these results can be foundations of further study of these target genes function.
METHOD:
SENP1, CD109, Laminin alpha 2, Laminin alpha 3 were selected according to the cDNA microarray results. The expression of these genes mRNA and protein were detected by RT-PCR and Western blot in 12 cases of LSCC and related adjacent normal tissues.
RESULT:
The mRNA expression of SENP1, CD109 and Laminin alpha 3 were significantly higher while Laminin alpha 2 were significantly lower in LSCC tissues than in corresponding adjacent normal tissues by Semiquantitative RT-PCR. Western blot analysis revealed SENP1, CD109 protein expression were significantly higher in LSCC tissues than in corresponding adjacent normal tissues.
CONCLUSION
SENP1, CD109, Laminin alpha 2 and Laminin alpha 3 may correlated with tumorigenesis and development of LSCC and can provide beneficial clue for study pathogenesis of LSCC in molecular level.

OBJECTIVE To evaluate the effectiveness, safety, economy, innovation, suitability and accessibility of recombinant Mycobacterium tuberculosis fusion protein (EC), and to provide evidence for selecting skin detection methods for tuberculosis infection diagnosis and auxiliary diagnosis of tuberculosis. METHODS The effectiveness and safety of EC compared with purified protein derivative of tuberculin (TB-PPD) were analyzed by the method of systematic review. Cost minimization analysis, cost-effectiveness analysis and cost-utility analysis were used to evaluate the short-term economy of EC compared with TB-PPD, and cost-utility analysis was used to evaluate the long-term economy. The evaluation dimensions of innovation, suitability and accessibility were determined by systematic review and improved Delphi expert consultation, and the comprehensive score of EC and TB-PPD in each dimension were calculated by the weight of each indicator. RESULTS The scores of effectiveness, safety, economy, innovation and suitability of EC were all higher than those of TB-PPD. The affordability scores of the two drugs were consistent, while the availability score of EC was lower than those of TB-PPD. After considering dimensions and index weight, the scores of effectiveness, safety, economy, innovation, suitability, accessibility and the comprehensive score of EC were all higher than those of TB-PPD. CONCLUSIONS Compared with TB-PPD, EC performs better in all dimensions of effectiveness, safety, economy, innovation, suitability and accessibility. However, it is worth noting that EC should further improve its availability in the dimension of accessibility.
