Objective：To study the surgical technique and results of surgical treatment for medial wall pyriform sinus cancer. Methods： A total of 122 patients with medial wall pyriform sinus cancer were surgically treated in our department between 1990 and 2001. Among them, 5 were in stage Ⅰ, 8 in stage Ⅱ, 37 in stage Ⅲ, and 72 in stage Ⅳ. Partial resection of the pyriform sinus and partial laryngectomy were performed on 87 cases. Epiglottis and sternohyoid myofascial flaps were used for laryngeal reconstruction. The remaining hypopharyngeal mucosa, pectoralis major musculocutaneous flap and colon interposition were used to cover the wound of hypopharynx and for artificial rebuilding. All patients received postoperative radiotherapy. Results：The overall 3 and 5year survival rates were 67.2％（82/122）and 45.1％（55/122）, respectively. In the preservative surgery group, the 3  and 5year survival rates were 71.3％（62/87） and 48.3％（42/87）, respectively, whereas those in the total laryngectomy group were 57.1％（20/35）and 37.1％（13/35）, respectively. Laryngeal functions were completely restored in 71.3%(62/87) and partially in 28.7% (25/87)of the total laryngectomy group. Conclusion： Although the medial wall pyriform sinus cancer tends to have a laryngeal invasion, preservative surgery should be practiced for the majority of patients after the lesions have been entirely removed.

Objective: To investigate the methods with a fascial flap of the strap muscles in reconstruction for hypopharyngeal carcinoma. Methods: Nine patients with hypopharyngeal cancer (stage Ⅱ, 1; stage Ⅲ, 4; and stage Ⅳ, 4; according to the UICC 2002 staging criteria) were surgically treated from June 1987 to June 1997. Lateral pharynx approaches were chosen based on the condition of process to perform the ablation of tumors, and fascial flap/muscular flap/ muscularfascial flap of the strap muscles were used to repair the defects and reconstruct the functions of larynx and pharynx. Adjutant radiation therapy of 6080Gy was performed on all cases. Results: All repair materials used were alive. One case suffered from postoperative wound infection and healed after constant rinsing and dressing changes. Two cases suffered from pharyngeal fistula and healed after dressing changes, rinsing and pressurizing. All patients′ laryngeal functions were preserved. All patients recovered diet within 12 to 35 days, with a mean time of 16.3 days. No pharyngosterosis and esophagostenosis happened. The 3 and 5year survival rates were 66.7%(6/9) and 44.4%(4/9), respectively. Conclusion: It is an available way to repair the defect of the hypopharyngeal paries anterior and the base of tongue with fascial flap/muscularflap/ muscularfascial flap of the strap muscles.

Objective：To study the surgical treatment and the simultaneous reconstruction methods for posterior hypopharyngeal wall carcinoma. Methods: Thirtyfive cases of the posterior hypopharyngeal wall carcinoma were retrospectively reviewed. According to UICC 1997 criteria, there were 2 in stageⅠ, 7 in stage Ⅱ, 10 in stage Ⅲ, and 16 in stage Ⅳ. Twenty cases preserved the complete or partial laryngeal functions and 15 cases accepted the total laryngectomy. Nineteen cases underwent an unilateral elective or modified radical neck dissection and 15 underwent a bilateral neck dissection. Thirtythree patients received radiotherapy postoperatively (5070?Gy). Results: The deglutition function was restored within 2 months. Vocal function was acquired in 20 patients preserving the laryngeal function and trachea cannulas were removed in 15 patients. The 5 and 3year survival rates were 31.6％（6/19）and 44.4％（12/27）, respectively. Conclusion: Carcinoma of the posterior hypopharyngeal wall are few in clinic. Surgical resection and onestage hypopharyngeal reconstruction are feasible. The pharyesophagus passage could be restored by retaining the mucosa, pectoralis major myocutaneous flap, laryngotracheal flap, split skin flap, stomach transposition and colon interposition etc.

Objective: To study the influence of firecrackers′ impulse noise on auditory function of normal growth children in a plateau area. Methods: Seventyone and 50 children were selected from the Qinling mountain area and the pasturing area around Qinghai Lake respectively. All of them were normal growth children (6 to 12 years old) who had experienced firecrackers′ noise over 3 times per year. In addition, 50 children from Nanjing city were included in this study. The entire frequency auditory threshold was examined on the spot. The auditory threshold was analyzed. Results: There was not a significant difference in high frequency and super high frequency between the pasturing area and the Qinling mountain areas, while the girls′ auditory function was same from all places. In contrast, the auditory thresholds in high frequency and super high frequency of the boys in Nanjing city was lower than those of the boys in both mountain area and plateau pasturing area. Conclusions: According to the auditory function of girls from all places, the hypoxia area of a plateau does not have any influences on children′s hearing development, and it also does not aggravate the auditory impact of the impulse noise of firecrackers on children.

Objective: To observe the expression of cyclindependent kinase4(CDK4) and cyclindependent kinase inhibitor P16 in human middle ear cholesteatoma and to explore their roles in the development of cholesteatoma. Methods: Thirtyfive cholesteatomas tissues and twenty normal human external ear canal skin were used in this study. All specimens were stained by an immunohistochemical SABC method to detect the expression of CDK4 and P16. Correlations between the above indexes and between the above indexes and the degree of ossicular destruction were investigated. Result: CDK4 and P16 were expressed in parabasal layers and the upper layer, mainly in the prickle and granular layers of cholesteatoma epithelium. Their positive rates were 68.6% and 88.6%, respectively. Statistical analysis showed that there was a significant difference in positive rates between the normal external ear canal epithelium and the cholesteatoma epithelium（P=0.011, P=0.02）, and a positive correlation between CDK4 and P16 in the cholesteatoma group(P＜0.05). The statistical results indicated that the expression of CDK4 and P16 did not related to the extent of ossicular damage in cholesteatoma(P＞0.05). Conclusion： CDK4 and P16 are overexpressed in human middle ear cholesteatoma epithelium and positively correlate with each other, suggesting that they play a cooperative role in the development of cholesteatoma. The cholesteatoma epithelium has a hyperproliferation ability and a mechanism of inhibiting the proliferation. The result of immunohistochemical examination is not related to the degree of ossicular destruction.

Objective: To investigate injury of the eustachian tube and middle ear by sinusitis in children and observe the recovery of the acoustic dysfunction after treatment for sinusitis. Methods: Examination of the ear, observation of the pharyngeal ostium of the eustachian tube， acoustic impedance tests, and pure tone audiometry were performed on 100 children with chronic sinusitis and 50 normal children. Of them, in 128 ears of 68 children sinusitis was found combined with ear diseases and then treated. Results: In children with sinusitis, the abnormal rate of the eardrum, the pharyngeal ostium of the eustachian tube , the function of the eustachian tube and the acoustic impedance tests was 64%, 62%, 63.5%, and 62.5%,respectively, and the rate of hearing loss was 47.5%. Compared with the normal children, the differences were statistically significant(P＜0.01). The differences of the incidence of middle ear disease and acute sinusitis, subacute sinusitis and chronic sinusitis were statistically significant between the two groups (P＜0.05). The acoustic dysfunction had a significant improvement after the treatment for sinusitis. Conclusion: The changes of the eustachian tube function caused by sinusitis lead to a significantly high incidence of middle ear disease.

Objective： Operation in the maxillary sinus tends to injure the debouchement of the nasolacrimal canal in the inferior nasal meatus and the walls of the fossa orbitalis. We tried to find a program with the least injury, duration and that was the most convenience. Methods： From March 2002 to the present, we designed an upright cut of 1 to 1.5 cm in the side labiogingival groove of the ill side above the canine tooth, separated to the bone in canine fossa, drilled a hole of 1 cm with an osteotome or electrodrill, removed the local mucosa, inserted an endoscope, and inspected the lesions inside. If submucous cysts were found, the capsule wall was removed and proper hemostasis was performed; if the mucosa was normal, there was no need to enlarge the aperture, an absorbable hemostatic gauze was laid in the wound surface and the hole, and sutured with 2 stitches; or adhered with biological glue. In patients with an antral polyp, the management was the same as the cases with sumucosa cyst. In patients with aspergillosis, we enlarged the apertures to 1-1.5cm, did not pack the nasal cavity, if we enlarged the apertures, we may pack expansive sponge. The face was oppressed with a four head belt, the plug was taken out after 48 or 72 hours according to the pathogenetic condition, and stitches were taken out after 4 or 5 days. Results： Primary healing was found in all 36 cases, with an unobstructed nasal cavity and disappearance of the symptom. No relapse was found in the period of four months to four years of followup; only 2 cases complained about transient numbness in the upper lips. All patients recovered after 7-8 days. Granulations were found in the enlarged aperture in 2 cases, and they disappeared after treatment. Conclusion： The feature of the operation is the small upright cut in the labiogingival grooves, small windowing in canine fossa, and delicate operation in the sinus cavity with a clear visual field. Lesions may be treated conveniently, which lead to less complications and less severe reactions. The maxillary sinus drains naturally, accords to the normal physiological functions and also problems are avoided that happen in other approaches.

Objective: To investigate the efficacy and mechanism of nebulized interferon gamma (IFN-r) in the prevention and treatment of allergic rhinitis. Methods: Ovalbumirl (OVA) absorbed to aluminum hydroxide was used to construct the allergic rhinitis model (group C), and nebulized IFN-r 12ug was inhaled once daily on day 23 to day 30. The nasal lavage fluid was collected on day 31, and the cellular constituents, levels of IL-4, IL-5 and IgE were determined. The normal control group (group A), the allergic rhinitic model group (group B) and beclomethasone dipropionate group (group D) consisted of five mice each. Results： Decrease of eosinophils (0.005±0.003)×104/ml was seen in nasal lavage fluid of group C as compared with group B［（0.223±0.068）×104/ml，(P<0.01)］, and the levels of IL-4(7.8±3.2pg/mL)　and IL-5(12.5±4.6pg/mL) decreased significantly in comparison with group B（P<0.01）. The serum levels of total IgE　(38.5±9.6ug/ml) and ovalbuminspecific IgE(19.6±5.2U/mL )decreased significantly in comparison with those of group B（P<0.01）. Conclusion： IFN-r can inhibit the composition of IL-4 and IL-5, and inhibit the airway inflammation with eosinophilic infiltration and the serum levels of total IgE and ovalbumin specific IgE, and so it is helpful in prevention and treatment of allergic rhinitis.

Objective: To screen for the differentially expressed genes in laryngeal squamous carcinoma cells and normal laryngeal tissues using cDNA microarray. Methods: The samples from two laryngeal squamous carcinoma tissues were tested using DNA microarrays. The DNAs were fixed on a glass plate by a series of treatments. The mixed probes were then hybridized to DNA microarrays and scanned for fluorescent signals. Differences between the two tissues were produced. Results: Ran belonging to Ras gene family increased 12.207 times, RAB32 belonging to Ras gene family increased 4.904 times and BIRC5 (Survivin) increased 15.495 times. They were significantly highly expressed in laryngeal cancer. The GFI1B gene decreased 0.0265 times. The GATA1 gene was significantly lowly expressed in one laryngeal cancer and was not expressed in carcinoma cells of another patient. Conclusion: cDNA microarray made in our Lab can recognize more than 7000 gene differences between cancer tissues and normal tissues at the same time and find gene variation. These results accord with other studys.
