导管

With the lapse of breeding years, the cultivars tended to have less root, shorter root length, larger active root absorption area, and smaller diameter of metaxylem vessel of seminal roots.

在以提高产量潜力为宗旨的品种更新替代过程中，不同年代春小麦品种随着年代推进逐渐呈现出根条数和根长减小、根活性吸收面积比增加、种子根中央大导管直径减小的趋势。

Rat AAA model was made by perfusion PPE elastase through the abdominal aorta, and the specimen was obtained on postoperativeday 3, 7, 14, 28, respectively. Specific elastic fiber staining was used to observe the disruption of elastic fiber in aortic wall. Immunohistochemistry staining of CD68 was applied to observe the microphage infiltration. The in tisu hybridization and western blot of MCP-1 and MMP-2 were used to study the expression of mRNA and protein. Thus we can analyze the facilitated function of MCP-1 gene to the microphage adherence and infiltration on the earlier AAA.

采用经腹主动脉腔内导管灌注的方法制成大鼠AAA模型，分别于术后3天、1周、2周、3周、4周获取各组大鼠腹主动脉标本，行弹力纤维特殊染色观察动脉壁弹力纤维的破坏情况；行CD68免疫组织化学染色观察动脉壁中巨噬细胞的浸润；行MCP-1及MMP-2的原位分子杂交、Western蛋白质印迹观察二者的mRNA表达和蛋白表达；分析MCP-1基因促进巨噬细胞的黏附、浸润在早期AAA发病中的作用。

Ductal carcinoma in situ, nuclear grade 1 / 2 / 3, solid / cribriform / papillary / micropapillary / apocrine type with minimal / moderate / comedo necrosis.

导管原位癌，核级别1/2/3，实性/筛状/乳头/微乳头/大汗腺型，伴有微小/中度/粉刺样坏死。

It was found that the test had 100% sensitivity and specificity to detect misplacement of SCV catheter into the ipsilateral IJV.

结果发现本试验检测SCV导管移位插入同侧IJV的灵敏度和特异性为100％。

Continuous infusion of local anesthetics also causes problems such as infection and catheter misplacement.

而为了连续给药所置入之导管，也常有位移和感染等问题。

Gastric residual volumes were also recorded to identify tube misplacement or migration.

同时记录胃残留量以辨别导管错位或偏移。

It is derived from dermal duct cells through mitosis and upward migration.

它是真皮导管细胞经有丝分裂向上延续而来。

Unilateral multicentric breast cancer are often distributed in the same quadrant or adjacent quadrants of breast,and the majority cases are with invasive ductal carcinoma.

全组单侧多中心性乳腺癌病灶多分布在同一象限或相邻象限，以浸润性导管癌为主，治疗方法采用乳腺癌改良根治术为主的综合治疗。

Objective To evaluate the feasibility and efficacy of the three-dimensional voxel imaging of multiplane transesophageal echocardiography in transcatheter closure of atrial septal defects.

目的 评价超声心动图和体元模型三维重建超声显像在经右心导管修补房间隔缺损中的价值。

Objective:To investigate the effect of automatic control narcosis in epidural block after normothermia patent ducts arteriosus ligature in congenital heart disease.

目的 ：观察先天性心脏病—动脉导管未闭患儿在常温下行结扎术术后硬膜外自控镇痛的疗效。
