        • Application of Low-temperature Bipolar Radiofrequency Ablation on Patients withMultilevel Obstructive Sleep Apnea-hypopnea Syndrome

          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。

        • Comparison between Two Culture Mothods of Endothelial Progenitor Cells Derived from Mice Bone Marrow

          【摘要】 目的 比較密度梯度離心法及全骨髓培養法分離培養內皮祖細胞的差異。方法 取4周雄性近交系C57BL/6J小鼠骨髓,分別使用密度梯度離心法及全骨髓培養法培養,觀察細胞貼壁情況和細胞形態,并行DiIacLDL及FITCUEAI雙染、vWF、eNOS及細胞表面標志檢測。結果 密度梯度離心法培養細胞可形成典型鋪路石樣改變及形成血管樣結構;而全骨髓培養法貼壁細胞形態多樣,較多呈長梭形鋪展生長,部分細胞呈類圓形及紡錘形。比較兩種方法培養細胞攝取DiIacLDL、結合FITCUEAI雙陽性率以及vWF、eNOS及細胞表面標志表達陽性率,差別均有統計學意義(Plt;005)。應用密度梯度離心法,隨著培養時間延長,表達CD34、CD133及FLk1細胞逐漸增多(Plt;005)。結論 密度梯度離心法及全骨髓培養法在EGM2MV培養體系下均可培養出內皮祖細胞,但密度梯度離心法較全骨髓培養法培養的內皮祖細胞純度高。

        • Expert consensus on prevention of mucormycosis secondary to viral respiratory infection

          The epidemiology of respiratory viruses in China are complex and diverse, and viral infections are prone to secondary mucormycosis, posing serious challenges to clinical and public health. The consensu is formulated by domestic experts organized by the Center of Infectious Diseases of West China Hospital of Sichuan University, aiming to identify high-risk groups of respiratory virus infection secondary to mucormycosis, and put forward systematic prevention suggestions. The content covers four aspects: education and training, personal protection, early diagnosis and treatment, and infection control, forming 11 specific recommended measures. It also points out the prevention measures that are still controversial or lack evidence and future research directions, in order to improve the understanding of clinical medical staff, optimize prevention and control strategies, and reduce the risk of secondary mucormycosis.
