Results (1)The agger cells existed in 99% of the cases, the development of the agger cells in 9～16 years old children, and adult had no difference;(2) The morphology of agger cells differed widely, but its relationship to the anterior border of the middle nasal concha, bulla ethmoidalis and nasolacrimal canal was quite stable;(3) The upward pneumatization of the agger cells was not related to deviation of nasal septum, but closely related to the development of the frontal sinus;(4) The anterior nasosinusitis often influenced the agger cells and might result in hyperosteogeny.

结果 ①绝大多数病例（99%）有鼻丘气房，儿童（9～16岁）鼻丘发育与成人相比无差异性；②鼻丘形态变化很大，但与中鼻甲前端、筛泡和鼻泪管的关系是恒定的；③鼻丘向上气化程度与额窦发育关系密切，鼻中隔偏曲对其发育无明显影响；④前组鼻窦的广泛炎症易波及鼻丘，并可出现鼻丘骨质增厚。

These relative risks did not change significantly after adjustment for age; sex; total cholesterol, low-density lipoprotein cholesterol, or triglyceride levels; carotid-wall thickness; smoking status; the presence or absence of diabetes and systolic and diastolic hypertension; body mass index; and other risk factors. In women, Lp lipoprotein levels were not related to cardiovascular risk, even after adjustment for estrogen use or nonuse.

Nowadays the single tube and single-unit hydroelectric station have been used widely and skillfully, but it is necessary for some large hydropower stations to use tailrace bifurcated tubes, just as Xiaolangdi, Xiangjiaba, Baishe project and so on. So it is significant to study the transients of long tailrace tunnel with tank or without tank.

对于尾水系统，单管单机的布置方式比较成熟，尾水岔管的布置方式目前在大型电站中用的较多，如小浪底、向家坝、百色等，因而研究其在有尾水调压井和无尾水调压井的情况下的过渡过程，很有实用意义。

Methods A prospective study of 48 patients with thoracolumbar junction burst fracture (T12-L2), 15 with and 33 without neurologic deficit were included. Computed tomographic scans were used to measure the sagittal and transverse diameters and the surface area of the spinal canal at the level of injury, as well as one level above and another level below the fracture level. Injury severity scores were calculated for both groups.

前瞻性研究48例胸腰椎(T12-L2)爆裂性骨折的患者，15例有脊神经功能障碍，33例无脊神经功能障碍，用CT扫描来测量损伤水平及损伤水平上下节段椎管的矢径、横径和椎管的表面积，两组病人都用ISS评分作损伤程度评估。

The backwall slides substantially in a contact-less manner within the tubular body, preferebly by way of a reduced diameter of the backwall (11) relative the inner diameter of the tubular body (8), so that it is pushed backwardly when the body retracts radially after actuation.

Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.

本研究结果显示，(1)单独应用TTE作为影像学引导进行冠状窦电极导管置放的成功率为93.8％～96.7％，并且应用TTE作为影像学引导放置专用冠状窦电极导管和普通电极导管的成功率和放置时间在统计学上无显著差异；(2)TTE作为影像学引导，除过度肥胖患者外，可完全替代X线引导进行冠状窦电极导管置放，包括鞘管和扩张管的放置、指引导丝在静脉而非动脉内的证实均可由TTE完成引导，且较X线C型臂有一定优越性；(3)TTE结合普通X线胃肠透视机作为影像学导引，可顺利完成心内电生理检查时导管的安全到位，而不需昂贵的X线C型臂，可将心内电生理检查扩大到广大的基层医院；(4)TTE较X线更易和更早期发现介入治疗的并发症如急性心包填塞等，对并发症的防治甚至挽救病人的生命至为重要；(5)动物实验研究表明，TEE可引导射频导管消融术时大头电极导管成功到位。
