Objective: To examine the safety and effectiveness of individualized treatment strategies that include three principles (security, top-down and priority) for patients with obstructive sleep apnoea hypopnea syndrome (OSAHS) and multilevel obstruction who decline therapy with continuous positive airway pressure (CPAP).
Methods: Patients with OSAHS and upper airway obstruction who were diagnosed with multilevel obstruction were included in this retrospective study. Patients were evaluated for the degree of obstruction in each level.

Objective: To explore the morphology, proliferative activity and adhesion of adipose-derived stem cells (ASC) seeded in the polylactic-co-glycolic acid (PLGA) scaffold, and to provide experimental data for fabricating tissue engineered tympanic membrane repairment materials.
Methods: Wistar rats were selected, and the ASC were isolated and co-cultured with the PLGA scaffold. The morphology and proliferative activity of ASC in the scaffold were examined by immunofluorescence of Vimentin and Ki67 respectively.
