摘要：目的：探討低溫雙極射頻消融技術治療多平面阻塞性睡眠呼吸暫停低通氣綜合征（obstructive sleep apnea-hypopnea syndrome，OSAHS）的價值。方法：對67例多平面OSAHS患者采用低溫雙極射頻消融治療，根據術前、術后癥狀改善情況及多導睡眠監測（polysomnography，PSG）結果的比較判定療效。結果：67例患者中治愈21例，顯效22例，有效15例，無效9例，總有效率86.57%。術前與術后1年AHI和SaO2結果經t檢驗，差異有顯著性(P＜0.01)。所有病例均無并發癥發生。結論：低溫雙極射頻消融術治療阻塞性睡眠呼吸暫停低通氣綜合征（OSAHS）療效肯定，特別是同期治療多平面阻塞安全可靠，具有獨特的優勢。
ObjectiveTo evaluate the quality of life after sentinel lymph node biopsy (SLNB) in patients with breast cancer. MethodsFrom January 2004 to December 2006, 591 patients with breast cancer who were suitable for SLNB were divided into SLNB group (n=339) and axillary lymph node dissection (ALND) group (n=252). All patients didn’t have the upper extremity joints disease, the vascular nerve disease, and the cervical spondylosis previously. Results①In patients with SLNB, the circumferences of upper arm in one, two, and three weeks after operation were similar to those before operation (P=0.232, P=0.318, and P=0.415, respectively). While, in patients with ALND, the circumferences of upper arm in one or two weeks after operation were significantly bigger than those before operation (P=0.011, P=0.041, respectively), and the circumference in three weeks after operation was similar to that before operation (P=0.290). ②In patients with SLNB, the outreach angles of shoulder joint in one and two weeks after operation were significantly smaller than those before operation (P=0.031, P=0.043, respectively), and the angle in three weeks after operation was similar to that before operation (P=0.196). However, in patients with ALND, the angles in one, two or three weeks after operation were significantly smaller than those before operation (all Plt;0.001). ③The retention time of drainage tube in patients with ALND who received breast conserving surgery or mastectomy was significantly longer than that in patients with SLNB who received mastectomy (all Plt;0.001). ④The infection rate and the sensory disjunction rate in patients with ALND were significantly higher than those in patients with SLNB (P=0.002, Plt;0.001, respectively). ConclusionsFor patients with lymph node negative breast cancer, SLNB could decrease postoperative complications, and improve the quality of life. It could also save money by reducing hospital stay.
