Allergen-induced CD11c + dendritic cell pyroptosis aggravates allergic rhinitis.

Background: Pyroptosis is crucial for controlling various immune cells. However, the role of allergen-induced CD11c + dendritic cell (DC) pyroptosis in allergic rhinitis (AR) remains unclear.

Methods: Mice were grouped into the control group, AR group and necrosulfonamide-treated AR group (AR + NSA group).

[Complications of hyoid suspension with Repose system on obstructive sleep apnea hypopnea syndrome].

Objective: To investigate the complications of hyoid suspension with Repose system on obstructive sleep apnea hypopnea syndrome (OSAHS) and to find out the effective prevention strategies.

Methods: Forty four patients diagnosed by polysomnography as OSAHS were received hyoid suspension with Repose system from June 2005 to July 2009. The intraoperative and postoperative complications were analyzed retrospectively.

[Complications of tongue base reduction with radiofrequency tissue ablation on obstructive sleep apnea hypopnea syndrome].

Objective: To investigate the complications of tongue base reduction with radiofrequency tissue ablation on patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and find out the effective prevention strategies.

Methods: One hundred and ninety three OSAHS patients diagnosed by polysomnography were received tongue base reduction with radiofrequency tissue ablation between March 2008 and December 2009. The intraoperative and postoperative complications including bleeding, hematoma of tongue base, abscess of tongue base, altered taste, tongue numbness, deviation of tongue extension movement, dysfunctions of pronunciation and swallowing as well as the managements were analyzed retrospectively.
