Research on the relationship between mucoepidermoid carcinoma and human papillomavirus infection / 中国耳鼻咽喉头颈外科

OBJECTIVE To find out the relationship between mucoepidermoid carcinoma and Human papillomavirus (HPV) infection.METHODS Nested polymerase chain reaction (Nested PCR) was adapted to detect HPV DNA from 51 tissues of mucoepidermoid carcinoma using consensus primers, 9 tissues of chronic parotitis were as control.RESULTS HPV DNA was detected in 37 of total 51 mucoepidermoid carcinoma tissues, the detection rate was up to 72.5%, comparatively, it was 22.2% (2 of 9) in chronic parotitis tissues. The HPV DNA detection rate of mucoepidermoid carcinoma tissues was statistically higher than that of chronic parotitis tissues (χ2=8.517, P=0.004).CONCLUSION The results suggested that the HPV infection may cause mucoepidermoid carcinoma.

Research on apoptosis changes of tensor veli palatini in patients with obstructive sleep apnea-hypopnea syndrome / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore apoptosis changes of dilator muscles in the upper airway by detecting the expression of Bax, Bcl-2 in tensor veli palatini in patients with OSAHS.@*METHOD@#The expression of Bax and Bcl-2 were detected in tensor veli palatini in 30 cases with OSAHS and 10 cases chronic tonsillitis without OSAHS by immunohistochemistry and image analytical system, and the results were analyzed.@*RESULT@#(1) The expression levels of Bax in the OSAHS group increased significantly compared to control group (P < 0.05), but there were no significant differences of Bcl-2 expression between two groups, the ratio of Bax/Bcl-2 increased significantly (P < 0.05). (2) There were positive correlations between AHI and the expression levels of Bax (r = 0.697, P < 0.01) respectively in the test group.@*CONCLUSION@#The results indicate that apoptosis occurred in tensor veli palatini in patients with OS AHS, and the more severity of OSAHS, the more apoptosis.

Objective:To explore apoptosis changes of dilator muscles in the upper airway by detecting the expression of Bax, Bcl-2 in tensor veli palatini in patients with OSAHS.Method:The expression of Bax and Bcl-2 were detected in tensor veli palatini in 30 cases with OSAHS and 10 cases chronic tonsillitis without OSAHS by immunohistochemistry and image analytical system, and the results were analyzed.Result:①The expression levels of Bax in the OSAHS group increased significantly compared to control group(P<0.05), but there were no significant differences of Bcl-2 expression between two groups, the ratio of Bax/Bcl-2 increased significantly(P<0.05). ②There were positive correlations between AHI and the expression levels of Bax(r=0.697,P<0.01) respectively in the test group.Conclusion:The results indicate that apoptosis occurred in tensor veli palatini in patients with OSAHS, and the more severity of OSAHS , the more apoptosis.
