    Objective: To study the expressions of Fas and Bcl2 in nasal polyps and explore the relationship between the two apoptosisrelated proteins in formation of nasal polyps. Methods: Expressions of Fas and Bcl2 were detected with SP immunohistochemical method in 36 nasal polyps and 19 inferior turbinates. Results: (1) The expression of Fas in epithelial cells and epithelial cells of glands was significantly lower in nasal polyps than in inferior turbinates(P<0.05); (2) The expression of Bcl2 in epithelial cells and epithelial cells of glands was significantly higher in nasal polyps than in inferior turbinates (P<0.05); (3) The expressions of Fas and Bcl2 had no correlation with each other in epithelial cells of nasal polyps(P>0.05). Conclusion: (1) Fas and Bcl2 may play important role in theoccurrence and progression of nasal polyps; (2) No relationship is found between Fas and Bcl2 in inhibiting the epithelial cells of glands of nasal polyps.

    :To investigate the effect of tongue base radiofrequency ablation (RFA) combined with uvulopalatopharyngoplasty(UPPP) for severe obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: The obstruction in both the oropharynx and the hypopharynx were determined by fiberoptic pharyngolaryngoscopy and Müller examination in 34 patients with severe OSAHS. All the patients accepted tongue base RFA plus UPPP. Results: The tongue base significantly reduced postoperatively, the apnea hypopnea index(AHI) was remarkably lower , and the minimum SaO2 was remarkably higher(P<0.001) 6 months and 1 year after treatment. The response rates were 100.00% (6month) and 91.18%(1year ). Conclusion: Tongue base RFA combined with UPPP is effective for severe OSAHS.

    To study the anatomy for the submental artery(SA) and submental veins(SV). Method:The area of the SA and the SV flaps in 21 human adult cadavers was measured. Results:The beginning diameter of SA was (1.41±0.32)mm, the largest diameter of SV was (2.41±0.91)mm, and the length and width of the flap were(78.2±13.9)mm and(55.6±5.4)mm, respectively. Conclusion:SA is a long, superficial and wide routine branch of facial artery with a routine drainage vein, and therefore it is perfect for mandibular basal flap.

    To evaluate the factors that lead to posterior capsule opacification (PCO) in cataract extraction. Methods: The clinical data of 53 patients with congenital cataract (87 eyes) reveiving cataract extraction through a scleral tunnel incision were retrospectively analyzed. Of them, the posterior capsule was left in 35 eyes, primary posterior continuous curricular capsulectomy (PCCC) was performed in 19 eyes, PCCC with an anterior vitrectomy (AV) in 33 eyes, and primary intraocular len (IOL) implantation in 51 eyes. Results: During a followup of 18 months, PCO occurred in 30 eyes (34.48%), including intact posterior capsule in 19 (54.29%) eyes, PCCC in 5(26.32%) eyes, PCCC+AV in 6(18.18%) eye, which may due to not performing PCCC+AV (P<0.01) or implantating primary IOL (P<0.05). Conclusion: Young in age, primary IOL implantation and intact posterior capsule are the risk factors for the formation of PCO.

    To evaluate the changes of astigmatism induced by 3.2?mm corneal tunnel incision and 5.5?mm scleral tunnel incision after phacoemulsification. Method: Phacoemulsification was performed on 64 cases 70 eyes) by 3.0?mm corneal tunnel incision and 5.5?mm scleral tunnel incision. Result: The eyesight and corneal astigmatism were not significantly different in the two groups 1 day, 1 week, 1 month and 3 months after operation. Conclusion: The corneal astigmatism after phacoemulsification is not significantly different between the two groups.
