OBJECTIVETo explore the relationship between trace elements and auditory function in the deafness children among ethnic minorities in Urumchi.

METHODSThere were 27 deaf-muted children in this study and 30 children with normal hearing as control. Sample of serum and hair from two groups were collected, and we tested 17 kinds of trace elements by using atomic absorption spectrophotometer and inductively coupled plasma emission spectrometer.

RESULTSThe content of trace elements in serum including Zn, Cu, Fe, Cd, Se, V and Pb from deaf-muted group was more higher than that of control group (P < 0.01), however, other trace elements including Mn, Sr, Sn, and Bi was much lower than that of control group (P < 0.01). Then, the content of those trace elements including Ba, Cr, Ag, Co, Ti, and Ni in serum from both testing and control groups was found no significant difference with each other (P > 0.05). On the other hand, the content of the trace elements including Sn and Se in hairs from deaf-muted group was more higher than that of control group (P < 0.05), but the content of the trace elements including Zn, Fe, Co, Mn, Sr, V, Pb, Ni, Cr, Ti and Ba in hairs from deaf-muted group was much lower than that of control group (P < 0.05), while the content of the trace element including Cu, Ag, Cd, and Bi in hairs from deaf-muted group was found no significant difference between each other (P > 0.05).

CONCLUSIONSThe content of some trace elements in serum and hairs of deaf-muted children is found a significant difference compared with children with normal hearing. This study indicates that some trace elements may relate to auditory function among ethnic minorities in Urumchi.

OBJECTIVE To evaluate the efficacy and the recovery of laryngeal functions of various kinds of partial laryngectomy for glottic carcinoma.METHODS The clinical data of 75 patients with glottic carcinoma who underwent partial laryngectomy in our department from Jan. 1997 to Dec. 2006 were retrospectively analyzed. Seventy one cases were male and 4 cases were female. There were 6 kinds of surgical methods for those patients. CO2 laser assisted vocal cordectomy was operated on in 12 cases,vocal cordectomy through laryngofissure in 18 cases,vertical partial laryngectomy in 33 cases,frontal partial laryngectomy in 5 cases,extended vertical partial laryngectomy in 4 cases,and CHEP in 2 cases. RESULTS The overall 3 and 5 year survival rates of the patients were 97.3% and 94.6% respectively. The 3 and 5 year survival rates in 48 cases with stage T1/T2 were 97.9% and 97.9% and those in 27 cases with stage T3/T4 were 92.5% and 85.1%. All of the patients restored the phonation and swallowing function. The decannulation rate was 92.1%(58/63). The decannulation rate of the patients within one month after operation was 85.2% CONCLUSION Partial laryngectomy is the first choice of the radical treatments for glottic carcinoma. Strict indications,correct procedure and surgical repair methods are the keys to ensure the efficacy and preservation of laryngeal function.

OBJECTIVE: Discussion of lung function changes in patients with allergic rhinitis and its clinical significance. METHOD: Using UNICAP100 allergen detector testing 64 patients of allergic rhinitis without asthma symptoms, testing the value of serum total IgE and using immunofluorescence methods for testing inhalation allergen, simultaneously checking the pulmonary function and bronchial provocation. Checking the lung function of 64 patients with non-symptoms of allergic rhinitis in other departments (control group), lung function were compared into two groups of patients. RESULT: In the allergic rhinitis group, 37 patients had abnormal lung function (57.81%), 8 cases in them had obstructive pulmonary ventilation, 12 cases had small airway dysfunction, 31 cases had increased airway resistance respectively. In the control group 15 patients (23.44%) had pulmonary function abnormalities, 2 cases had obstructive pulmonary ventilation, 4 cases had small airway dysfunction, 11 cases had increased airway resistance respectively. Changes in lung function compared in the two groups was statistically significant (P < 0.05). Allergic rhinitis patients with abnormal lung function bronchial provocation test positive rate was significantly higher than the normal lung function in patients with allergic rhinitis, there had statistically significant difference between the two groups (P < 0.05). CONCLUSION After checking the lung function of non-asthmatic symptom patients with allergic rhinitis, we could find abnormal lung function patients of allergic rhinitis and do bronchial provocation test in them, there has important clinical significance of early detection and treatment the patients of allergic rhinitis with bronchial asthma.

OBJECTIVE: To study the correlation between the bacterial biofilm formation and bacterial culture in chronic otitis media. METHOD: As a prospective reserch, we used scanning electron microscopy to examinate patients samples which collected from 32 cases of patients with chronic suppurative otitis media and middle ear cholesteatoma in the operations, and performed the middle ear secretions bacterial culture. According to the different types of chronic otitis media group, we analysised the relationship between chronic otitis media bacterial biofilm formation and the bacterial culture results. RESULT: Chronic suppurative otitis media (activity) and middle ear cholesteatoma bacterial biofilm formation rate were 87.5%, 81.3%, chi-square (P > 0.05). Compared bacterial biofilm results with the results of bacterial cultured in chronic otitis media, sensitivity was 70.37%, specificity was 60.00%, the misdiagnosis rate was 40.00%, the missed diagnosis was 29.63%, positive predictive value was 90. 46%, negative predictive value was 27.27%, accuracy was 68.75%. Youden index was 30. 37%, and Pearson correlation coefficient was 0.232 (P > 0.05). CONCLUSION Chronic suppurative otitis media (activity) and middle ear cholesteatoma bacteria had a higher biofilm formation rate. The routine bacterial culture results can't reflecte bacterial biofilm formation in chronic otitis media. We need to explore more reliable experimental methods to accurately reveal the infection status of chronic otitis media.

OBJECTIVE: To evaluate the treatment policy for non-Hodgkin's lymphoma of the nasal cavity and nasopharynx. METHOD: Twenty patients with pathologically confirmed non-Hodgkin's lymphoma of nasal cavity and nasopharynx,treated from Jan. 2006 to Oct. 2010, were retrospectively reviewed. RESULT: The 3-year overall survival and complete response rates for all patients were 78% and 47% respectively. The 3-year overall survival rates for patients treated with chemotherapy and patients treated with chemotherapy plus radiotherapy were 75% and 82% respectively. The estimates of complete response for patients receiving chemotherapy alone and for patients receiving chemotherapy plus radiotherapy were 37% and 55%, respectively. The 3-year overall survival rates for patients who achieved complete response and patients who did not were 89% and 70%, respectively. The 3-year overall survival rates for patients in stage IE and stage II E were 92% and 57%, respectively. CONCLUSION There was no significant difference between chemotherapy alone and chemotherapy plus radiotherapy for the treatment of non-Hodgkin's lymphoma of the nasal cavity and nasopharynx. The 3-year overall survival rate for patients in stage IE was much higher than in stage II E. Early treatment is very important to improve the survival rate of the patients.

OBJECTIVETo investigate the therapeutic effect of drug treatment for patients with sudden sensorineural hearing loss (SSNHL) accompanied with feeling of ear fullness (FEF).

METHODSA prospective clinical multicenter research was carried out from August 2007 to October 2011. SSNHL patients aged between 18 to 65 years old and accepted no medication were recruited, with a duration less than two weeks. The patients were divided into four types according to the hearing curve: type A was acute SSNHL in low tone frequencies, type B was acute SSNHL in high tone frequencies, type C was acute SSNHL in all frequencies, and type D was total deafness. Each type was subdivided into two groups by the accompaniment of SEF or not. And each type had four different treatment programs, based on the unified designed randomized table. All patients were followed up for four weeks from the initial examination.

RESULTSA total of 1 024 cases with single side SSNHL were recruited in the study from 33 hospitals in China, including 565 cases accompanied with FEF (55.18%), and 459 cases without FEF (44.82%). By classification of audiogram, 205 cases were type A (20.20%), of whom 122 were accompanied with FEF (59.51%); 141 cases belonged to type B (13.77%), of whom 74 were accompanied with FEF (52.48%); 402 cases were type C (39.25%), of whom 229 were accompanied with FEF (56.97%); and 276 cases were classified as type D (26.95%), of whom 140 were accompanied with FEF (50.72%). No significant difference was observed in total effective rate between the SSNHL patients accompanied with FEF or not in four acoustic types (P > 0.05). Among four acoustic types, the clinical cure rate of patients accompanied with FEF in type A was 93.44%, ranking the first; followed by 84.28% for type C; 75.71% for type D; and 70.27% for type B, respectively.

CONCLUSIONSThe therapeutic effect for patients accompanied with FEF in type A is satisfactory. The presence of FEF do not impact the therapeutic effect for SSNHL patients.
