查询词典 patency

By the examination of MRI, histopathology, and the caculation of survival rate and percentage of patency, the viability of graft status of autograft tracheas wrapped in one-side sternomastiod muscule flap and two-side sternohyoid muscle flap based on different pedicle, effects of neck muscle associated with bFGF on length of autografts, and limit of warm ischemia time on tracheal allograft before cryopreservation were evaluated in rabbits.

肿瘤、先天性疾病、炎症或其他原因引起的气管狭窄，切除病变气管行气管端端吻合术是最理想的方法。而长段气管切除术后，则需要行气管重建。20世纪以来随着免疫学的发展，肾脏、心脏等脏器移植已在临床应用成为可能，人们注意到气管移植的重要性。因此，气管移植成为长段气管缺损重建的方向，其面临的主要问题是移植气管的再血管化、免疫抑制、供体的来源与保存等。

By the examination of MRI, histopathology, and the caculation of survival rate and percentage of patency, the viability of graft status of autograft tracheas wrapped in one-side sternomastiod muscule flap and two-side sternohyoid muscle flap based on different pedicle, effects of neck muscle associated with bFGF on length of autografts, and limit of warm ischemia time on tracheal allograft before cryopreservation were evaluated in rabbits.

Onclusions-: Radial artery aortocoronary bypass grafts to a stenosed branch of the circumflex coronary artery have an excellent patency rate at 5 years.

在五年中桡动脉主动脉冠状动脉旁路移植对狭窄的冠状动脉具有优良的通畅率。

Methods and Results-: We enrolled 142 patients randomized at a single center to have either the radial artery or saphenous vein grafted to a stenosed branch of the native left circumflex coronary artery. The primary end point was angiographic graft patency 5 years postoperatively.

方法和结果：我们通过单中心随机试验对左冠状动脉狭窄进行桡动脉或隐静脉移植的142例病人进行研究，主要的终点利用血管造影对移植的血管进行监测5年。

The modified rat laryngeal transplantation model improves survival rate of allograft and vessels patency rate, compared with those of Strome model.

结伦：大鼠喉移植改良模型提高了受体大鼠和移植喉的存活率，优于Strome模型。

Methods Eighty Class Ⅱ isogeneic F344 rats, weighing 250-350 g, were randomly divided into 2 groups(n=40). The control group adopted the Strome model. The allograft used for the experimental group preserved ascending pharyngeal artery, which formed a complex allograft together with tongue base, larynx and pharyngolarynx. End-to-end anastomosis was performed between both allograft common carotid arteries and anterior neck veins. The patency rate and survival rate of the allograft of the 2 groups were compared.

80只Ⅱ级近交系F344大白鼠，体质量250~350 g，随机分为2组，每组40只，共20对对照组采用Strome喉移植模型，实验组在切取供体喉时保留咽升动脉，将舌根、喉、喉咽作为复合移植体，供体大鼠双侧颈蓉动脉分别与受体大鼠颈总动脉、颈前静脉进行端端吻合重建移植喉血液循环，比较两组术后动静脉通畅率及移植喉存活率。

Methods: Proceed hysterosalpingography and patency test using acoustic contrast agents in stead of iodipin and observe the uterotubal ultrasonographic images under the conditions of transvaginal sonography and CDPI.50 infertility women were observes by transvaginal sonography,Ultrasongraphic hysterosalpingographyand color Doppler imaging,analyses the character of dynamic ultrasound images.

利用超声声学造影剂代替碘油行子宫输卵管造影及通液术，并在实时阴道超声及CDPI状态下，观察子宫输卵管动态超声图像特征。
