导管

The degree of lignification varies from slight in protoxylem to heavy in sclerenchyma and some xylem vessels, but values of 25-30% lignin and 50% cellulose are average.

不同部位的木质化的程度不同，原生木质部中只有轻微的加厚，而在厚壁组织和一些木质部导管中则进一步加厚，平均含25％-30％的木质素和50％的纤维素。

Antegrade percutaneous access was obtained by X-ray perspective or B-type ultrasound guidance. A combination pneumatic and ultrasonic lithotrity was used to disintegrate and remove stone under direct vision.

患侧输尿管于膀胱镜下逆行留置5F输尿管导管，推注生理盐水以充盈肾盂。X射线透视或B超引导下穿刺目标肾盏，建立皮肾通道，肾镜下采用气压弹道联合超声碎石术。

Results 78 patients included infiltrating ductal carcinoma 40 cases,infiltrating lobule carcinoma 24 cases,ductal carcinoma in situ 14 cases.

结果 浸润性导管癌40例，浸润性小叶癌24例，原位癌14例。

Mainly the breast development procedure is a three-phase procedure- lobule development, glandular development and shrinkage of the milk ducts.

主要是乳房发育过程是一个三阶段程序，小叶发展，腺体发展和收缩的牛奶导管。

The general infection rate was 21.5%. 12 cases were local infection, and 9 cases was catheter planting, including 2 cases of blood infection related with blood vessel.

结果 采集标本80份，总感染率为21.5%，局部感染12例，导管种植9例，其中包括2例血管相关性血行感染。

The duct consists of a single layer of inner or luminal cells and two or three outer rows of cells.

导管由单层内细胞和二至三层外细胞组成。

This appears to be a ductal carcinoma of mammary gland.

这似乎是乳腺导管癌。

Materials and Methods:The clinical and imaging characteristics of 74 cases with mammary hyperplasia were analyzed retrospectively.

材料和方法：回顾性分析74例乳腺增生症的临床和影像学表现。74例均做了钼靶X线摄影检查，其中19例做了选择性乳腺导管造影、10例超声检查和3例核磁共振检查。

Retaining manometric tube in radial artery and polysomnography were done synchronously in 13 patients with OSAS in whom was diagnosed by whole-night PSG.

13例OSAS患者在桡动脉内留置导管监测血压并同步进行夜间睡眠多导生理仪连续记录，部分患者观察吸氧或经鼻罩持续正压通气的治疗效果。

Methods:With gastric esophagus manometric catheter designed by ourselves, the gastric proximal end compliance and gastric proximal end sense threshold of 9 healthy volunteers and 31 RE patients were measured when gastric proximal end pressure increasing.

采用自行设计的胃食管一体式导管，在不断增加胃近端压力时，同步测量 9例健康志愿者和 31例 RE患者的胃近端顺应性和感觉功能。结果和结论：RE组胃近端感觉阈值显著低于正常组。 RE组及正常组的最小感觉阈值、较强感觉阈值、最大耐受阈值分别为：190± 12 3、316± 130(P 。0 5 )；2 5 0± 10 7、45 1± 95 (P 。0 1)；314± 92、480± 75 (P 。0 1)。
