We first successfully treated an APL patient with leli internal carotid artery rupture during chemotherapy leading to PSA using ultrasound-guided thrombin iniection （UGTI）.展开更多
目的:评估内皮型一氧化氮合酶(Endothelial nitric oxide synthase,eNOS)基因治疗对大鼠缺血后肢血管新生的影响。方法:局麻下将30只雄性SD大鼠后肢缺血模型制作后,随机分成实验组和对照组,每组15只。模型制作后1周,采用肌肉注射的方法...目的:评估内皮型一氧化氮合酶(Endothelial nitric oxide synthase,eNOS)基因治疗对大鼠缺血后肢血管新生的影响。方法:局麻下将30只雄性SD大鼠后肢缺血模型制作后,随机分成实验组和对照组,每组15只。模型制作后1周,采用肌肉注射的方法,实验组缺血后肢接受载有eNOS基因的5型重组腺病毒治疗,对照组接受生理盐水治疗。eNOS基因治疗后4周,评估SD大鼠踝部动脉压、微循环灌注、数字减影血管造影、组织微血管计数以及eNOS蛋白的表达。结果:eNOS基因治疗后4周,和对照组相比,接受eNOS基因治疗的大鼠缺血肢体,表现了更好的血流恢复(踝部动脉压(mmHg):58.2±4.7 vs 86.8±4.3,P<0.01;微循环灌注:142.0%±21.5%vs 219.6%±26.2%,P<0.01)、侧枝开放和血管新生(血管造影:6.7±1.1 vs 14.4±1.7,P<0.01;微血管/肌纤维比值:0.34±0.03 vs 0.56±0.02,P<0.01)以及eNOS蛋白的高表达(0.46±0.02 vs 0.73±0.02,P<0.01)。结论:eNOS基因治疗促进SD大鼠缺血后肢的血管新生。展开更多
