Objective:To investigate the abnormality of the craniofacial and upper airway structure in adults with obstructive sleep apnea syndrome(OSAS).Methods:The craniofacial skeletal and upper airway morphology of 31 male adult patients with OSAS was measured by cephalometry and compared with that of a control group consisting of 16 male asymptom adults. Results:The significant aberrations in the OSAS group were: relative increased ANB and NA/PA(P

Objective To investigate causes and treatment approaches for postoperative complications after laparoscopic adjustable gastric banding(LAGB).Methods Clinical and follow-up data of 302 cases were reviewed.The body mass index (BMI),percent excess weight loss (％ EWL),operation time,intraoperative blood loss,the incidence of complications and management were analyzed and summarized.Results There were no conversion to open surgery.The overall complication rate was 6.29％ including 2 cases of gastric wall injury,5 cases of gastric banding slippage (recovered by reoperation).There was no gastric parietal banding corrosion,tube bursting leakage,pulmonary embolism,micronutrient deficiencies,nor mortality.Conclusions The majority of patients were satisfied with the operation effect,still,there were substantial postoperative complications including gastric wall injury,gastric banding slippage.

Objective : To investigate the clinical use of glass ceramic onlay in the restoration of the non-vital posterior teeth with computer aided design and computer-aided manufacturing technique (CAD/CAM). Methods : 70 patients with 75 teeth of residual crown were selected and restored with CAD/CAM glass-ceramic onlay after completely root canal therapy. Marginal adaptation, anatomic form, adjacent relation, contour appearance, color match were checked in 12-month follow-up. Results : Marginal adaptation, anatomic form, adjacent relation, contour appearance, color match of 73 teeth were satisfactory and 2 cases was excluded because of lost to follow-up. There were no significant differences in the number of cases which met clinical criterion A or B between immediate restoration and 12-month follow-up (P > 0.05), and more than 95% of cases met clinical criterion A. Conclusion The CAD/CAM glass-ceramic onlay in the restoration of non-vital posterior teeth can provide better effect of retention and esthetics in a short term observation of 12 months.

This research evaluated the clinical efficacy of three-wings rib plate in the treatment of multiple rib fractures and flail chest with mechanical analysis and clinical verification. The model of rib and three-wings rib plate was reconstructed. The contact simulation with pretension stress was applied to the plate's fixation, and it was found that the bearable stress of the rib fractures after fixation increased from the result which indicated a good fixation efficacy of the plate. Clinical data of 53 cases of rib fractures and flail chest treated with three-wings rib plate in Shanghai Pudong Hospital of Fudan University were retrospectively analyzed. After the operation, the pain of the patients was relieved. Postoperative CT reconstruction of the chest showed good restoration of the rib fractures, which verified the clinical efficacy of three-wings rib plate. The three-wings rib plate showed a high value in clinical use for treatment of rib fractures.
