Clinical Observation of Different Administration of Dexamethasone in the Treatment of Secretory Otitis Me-dia / 中国药房

OBJECTIVE:To observe the efficacy and safety of different administration of dexamethasone in the treatment of se-cretory otitis media. METHODS:Data of 92 patients with secretory otitis media was retrospectively collected and divided into ob-servation group(43 cases)and control group(49 cases)by different administration. Observation group received 5 mg Dexametha-sone injection by injection in the eustachian tube in the assisted by video laryngoscope,once every 2 day. Control group received 5 mg Dexamethasone injection by injection in the eustachian tube,once every 2 day. 7-day was regarded as 1 treatment course. 1 more course for uncured patients,and no more than 4 courses. Clinical efficacy,and tumor necrosis factor-α(TNF-α),C-reactive protein(CRP),interleukin-6(IL-6),IL-10 levels before and after treatment,and 1-year cumulative recurrence rate after cured and the incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was signifi-cantly higher than control group,1-year cumulative recurrence rate after cured was significantly lower than control group,the dif-ferences were statistically significant(P0.05). After treatment,TNF-α and IL-6 level in 2 groups were significantly lower than before, and observation group was lower than control group,the differences were statistically significant(P0.05). And there was no significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:The efficacy of dexamethasone by injection in the eustachian tube in the assisted by electron-nasopharyngolaryngoscopy is superior to auripuncture administration,it can reduce re-currence rate,with good safety.

The expression and significance of programmed cell death 5 and Bcelllymphoma/lewkmia-2 in sinonasal squamous cell carcinoma / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the expression and significance of programmed cell death 5 (PDCD5) and Bcelllymphoma/lewkmia-2(Bcl-2) in sinonasal squamous cell carcinoma (SNSCC).@*METHOD@#Immunohistochemical method and Western Blot method was used to determine the expression of PDCD5 and Bcl-2 in specimen of SNSCC in thirty cases, sinonasal inverted papillomas (SNIP) in thirty-eight cases, and normal nasal mucosa in twenty cases.@*RESULT@#(1) The expression of PDCD5 protein in SNSCC significantly decreased compared with SNIP and normal nasal mucosa. (2) The expression of Bcl-2 protein in SNSCC up-regulated obviously compared with SNIP and normal nasal mucosa. (3) Positive rate of PDCD5 protein and Bcl-2 protein in well, moderate and low differentiatied group is respectively 100.00%, 83.33%, 38.89% and 50.00%, 70.83% and 100.00%, the difference was statistically significant (P < 0.05). (4) In the follow-up cases, the survival rate of the patients with higher expression of PDCD5 protein was higher, but that with lower expression of Bcl-2 protein was higher.@*CONCLUSION@#The inactivation of PDCD5 protein and the activation of Bcl-2 protein may play an important role in the development of SNSCC, and there are a positive correlation between PDCD5 and Bcl-2 protein in SNSCC, which may be identified as a new therapeutic target.

The correlation studies between recurrent otitis media and adenoid hypertrophy in children / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the relationship between the immune status of adenoids and secretory otitis media (SOM).@*METHOD@#The adenoids tissue samples of 30 cases of recurrent secretory otitis media (SOM), 17 cases of non-recurrent secretory otitis media and 20 cases of the adenoids hypertrophy without SOM were studied by immunohistochemical method.@*RESULT@#The expression of PCNA, BCL-2, CD4+, CD8+ cells and CD4+/CD8+ in recurrent SOM tissue were 30.85 +/- 1.73, 21.27 +/- 1.25, 41.90 +/- 9.07; 20.45 +/- 7.08 and 2.10 +/- 0.17, respectively, which was remarkably higher than those of non-recurrent SOM, (25.50 +/- 1.66, 14.23 +/- 1.06, 17.40 +/- 6.85, 13.02 +/- 5.88, 1.33 +/- 0.11, respectively) and those of simple adenoid hypertrophy (25.25 +/- 1.75, 14.05 +/- 1.02, 16.30 +/- 8.21, 11.15 +/- 5.71 and 1.39 +/- 0.15, respectively) (P 0.05). In group of simple adenoid hypertrophy, PCNA in the subgroup of the age 3 to 6 was significantly higher than those in the other groups (P < 0.05).@*CONCLUSION@#In adenoid tissues of recurrent SOM patients, the activities of T-lymphocyte subsets cells in hypertrophic status increase, the adenoids enlarge and local immunity enhances. The age and gender have nothing to do with the SOM, but low age is one of the influencing factors of adenoid hypertrophy. Therefore, adenoidectomy for recurrent SOM patients with adenoid hypertrophy should be carried out as early as possible.

Expression of PCNA, BCL-2, CD4+, CD8+ in the adenoid tissues from children with secretory otitis media / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the relationship between immune status of adenoids and secretory otitis media (SOM).@*METHOD@#The adenoid tissue samples of 72 cases with SOM and 30 cases with adenoid hypertrophy without SOM were studied by immunohistochemical method.@*RESULT@#The PCNA, BCL-2, CD4+, CD8+ and CD4+ / CD8+ in SOM tissue samples were 30.85 +/- 1.73, 21.27 +/- 1.25, 41.90 +/- 9.07, 20.45 +/- 7.08 and 2.10 +/- 0.17, respectively, which were much more than that of tissue samples without SOM (25.25 +/- 1.75, 14.05 +/- 1.02, 16.30 +/- 8.21, 11.15 +/- 5.71, 1.39 +/- 0.15 respectively) (P < 0.01). The expression of CD4+ in T-lymphocyte was obviously higher than that of CD8+.@*CONCLUSION@#In adenoid tissues of SOM patients, the activity of T-lymphocyte subsets are increased,the adenoids are enlarged and local immunity are enhanced. Therefore,adenoidectomy should be applied in SOM patients as early as possible.
