植入管

OBJECTIVE: To explore the clinical mechanical property of spinal nonfusion interspinous U titanium alloy.

目的：观察腰椎后路动态腰椎管狭窄运动保留的非融合U型棘突间钛合金材料植入物的临床力学性能。

Summary of Background Data. The X Stop Interspinous Process Distraction Deice is a relatiely new interspinous implant designed for patients with symptomatic spinal stenosis particularly neurogenic claudication.

背景资料概述：对于存在腰椎管狭窄症并有神经源性跛行表现的患者而言，X STOP是一种相对较新的棘突间植入装置。

The heights and free edge lengths of cusps in the VAHCs implanted in th e 6 months were higher than those of the control VAHCs (P.05). Light micr o scopic examination of the explanted VAHCs revealed intimal and media proliferati on, cellular infiltration and valvular thickening.

组织学检查显示VAHC血管壁存在三层结构，内膜及中层轻度增厚，管壁有少量单核细胞及淋巴细胞浸润，植入成年兔体内6个月的变化最为明显。

The Titanium implants can be well conjugated with the tubiform bone, and there is no difference between the three months and the six months after the implantation, mechanical measurement reached ideal.

钛种植体种植在管状骨中亦可形成良好的界面愈合，植入后3月和6月骨钛界面愈合情况无明显区别，力学测试均达到理想的指标。

Rat models were successfully established by twice operations. First, OJ was induced by common bile duct ligation and division. On the 7th day after the first operation, ED was performed by exteriorizing a drainage tube at the nape of the rat, while ID by implanting a drainage tube between the dilated end of CBD and duodenum.

采用成年雄性Sprague Dawley大鼠60只，随机分成梗阻性黄疸、胆汁内引流、胆汁外引流和假手术4组，每组15只，通过第一次开腹手术结扎并切断胆总管建立OJ模型，术后7天第二次手术，从膨大的胆管末端插入并固定引流管，经皮下固定于大鼠颈背部皮肤建立ED模型；ID模型通过在膨大的胆管末端和十二指肠间植入支架形成。

The pedicle screw in the right position had considerable artifact, which influenced the images of lateral spinal canal, foramina, nerve root, and posterolateral herniated disc.

正确植入的椎弓根螺钉伪影也较大，主要影响对邻近部位椎管侧方、椎间孔、脊神经和后外侧突出的椎间盘等结构的观察。

Group 1 with fixation of facet joint screw had a significant increase in stiffness for extension, bilaleral bending, and colockwise rotation.

经侧后方斜向植入的单枚椎间融合器加上小关节突螺丝钉内固定融合术，在提供充分椎管减压的同时，具有损伤小、脊柱后部稳定性好、术中对马尾及神经根牵拉轻的优点，可以比较理想地取代后路双枚融合器椎间融合术。

We sum up the experiences of 52 eyes in 46 cases with lacrimal duct obstruction and chronic dacryocystitis treated by artifical tube implanted into nasolacrimal duct. Result: The cure rate was 95% after followed up for 3～6 months.

分析总结46例（52只眼）行鼻泪管内义管植入术治疗泪道阻塞及慢性泪囊炎患者的护理经验，结果：术后随访3～6月，治愈率为95%。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
