OBJECTIVE There are several treatments for obstructive sleep apnea syndrome, such as weight loss, use of an oral appliance and continuous positive airway pressure, that can be used to reduce the signs and symptoms of obstructive sleep apnea syndrome. Few studies have evaluated the effectiveness of a physical training program compared with other treatments. The aim of this study was to assess th...

Objective: To investigate the curative effect of the plasma low-temperature radiofrequency ablation (RFA) on ineffective obstructive sleep apnea hypopnea syndrome (OSAHS) after uvulopalatopharyngoplasty (UPPP). Method: 39 cases of OSAHS which were ineffective after UPPP were chosen to accept RFA. Preoperative apnea hypopnea index (AHI), lowest saturation of blood oxygen (LSaO2), snoring scale a...

To better understand how humans adapt to hypoxia, the levels of hemoglobin (Hb), serum erythropoietin (Epo), and vascular endothelial growth factor (VEGF) were measured in 106 patients with severe obstructive sleep apnea-hypopnea syndrome. The results indicated that temporal hypoxic stimulation increases Hb. Furthermore, a minor increase in Epo and a substantial increase in VEGF were found. The...
