后胸后侧片

OBJECTIVE: To observe the characteristics of vertebral pseudoarthrosis after thoracolumbar vertebral compression fracture in five lateral radiographies.

目的：观察胸腰椎椎体压缩性骨折后椎体假关节的5种体位X射线侧位平片的特点。

BACKGROUND: Many clinical studies have demonstrated that pseudoarthrosis formation after thoracolumbar vertebral compression fracture is often assessed using lateral films.

摘要背景：许多临床研究阐述了胸腰椎椎体压缩性骨折后应用常规侧位片来评定是否有假关节形成，作者所查应用仰卧或俯卧侧位X射线片来诊断椎体真空征的文献较少。

Supine or prone lateral radiographs can precisely show vertebral pseudoarthrosis following thoracolumbar vertebral compression fracture.

仰卧、俯卧侧位X射线片能更为精确的显示胸腰椎椎体压缩性骨折后椎体假关节的存在。

Methods On same oral therapy condition,the patients in control groupwere given commmon thoracocentesis on twice a week,the patients in experimental groupwere treated by thoracic tube intubation with veinal catheter.After drainage within3days,the pleural cavity of the paˉtients in group E were injected with the compound of sodium hyaluranate,sodium carboxymethylcellulose and butyltriˉamcinolone.The patients of two groups were examined by X-ray after6months.According to the database of normal crowd chest X-ray photograph,the area of patient's photograph was drawn.The value of average gray scale in the area was gathered by image analysis system and to be compared with the value of normal side,so the gray ratio was got after correction.

在口服给药条件一致的前提下，对照组患者沿用常规每周2次间断抽液的方法；实验组采用静脉留置针持续引流的方法，3日内将胸液引流尽后注入由透明质酸钠、羧甲基纤维及丁基去炎松组成的可吸收生物活性凝胶。6个月后行胸片检查，图像分析系统根据正常人群胸片同侧拟合区域采集平均灰度值并与健侧相比，经校正后得灰度比。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
