改良哈氏棒治疗胸腰段脊柱不稳定骨折

本文报告了作者研制的改良哈氏棒治疗胸腰段脊柱不稳定骨折的临床效果。１９９１年１月～１９９４年１０月，治疗２６例，伤椎椎体前缘高度从４１．９１％，恢复至９５．５７％，椎体后缘高度从８１．０３％恢复至１００％，后凸畸形（Ｃｏｂｂ氏法）从２６°恢复至５°，有５例恢复前凸８°～１０°，神经功能恢复１．８级（Ｆｒａｎｋｅｌ分级）。作者认为回复生理前凸的纵轴上纵向撑开力，更有助于胸腰段脊柱骨折的解剖复位。

新生儿呕吐性疾病的消化道造影研究

目的:研究新生儿呕吐性疾病的造影技术,探讨其影像特征。方法:对比剂引入方式采用吸吮法和插胃管抽液后再注入对比剂两种方法;选用对比剂有6 0 %～80 % (W/V)的硫酸钡混悬液30～4 0ml或30 %泛影葡胺30ml;采用不同体位多轴位观察摄片,并对5 4例造影表现进行分析。结果:5 4例新生儿消化道造影均满足诊断要求,其中先天性幽门狭窄11例(19 6 % ) ,胃食管反流34例(6 3 0 % ) ,环形胰腺9例(16 .7% )。经手术治疗2 0例均与术前X线诊断相一致。结论:传统的上消化道造影是诊断新生儿呕吐病因的有效方法,熟练掌握造影技术和特有的造影征像能够及时地明确诊断。

Serial CT findings of Paragonimus infested dogs and the Micro-CT findings of the worm cysts.

OBJECTIVE: To investigate the serial CT findings of Paragonimus westermani infected dogs and the microscopic structures of the worm cysts using Micro-CT. MATERIALS AND METHODS: This study was approved by the committee on animal research at our institution. Fifteen dogs infected with P. westermani underwent serial contrast-enhanced CT scans at pre-infection, after 10 days of infection, and monthly thereafter until six months for determining the radiologic-pathologic correlation. Three dogs (one dog each time) were sacrificed at 1, 3 and 6 months, respectively. After fixation of the lungs, both multi-detector CT and Micro-CT were performed for examining the worm cysts. RESULTS: The initial findings were pleural effusion and/or subpleural ground-glass opacities or linear opacities at day 10. At day 30, subpleural and peribronchial nodules appeared with hydropneumothorax and abdominal or chest wall air bubbles. Cavitary change and bronchial dilatation began to be seen on CT scan at day 30 and this was mostly seen together with mediastinal lymphadenopathy at day 60. Thereafter, subpleural ground-glass opacities and nodules with or without cavitary changes were persistently observed until day 180. After cavitary change of the nodules, the migratory features of the subpleural or peribronchial nodules were seen on all the serial CT scans. Micro-CT showed that the cyst wall contained dilated interconnected tubular structures, which had communications with the cavity and the adjacent distal bronchus. CONCLUSION: The CT findings of paragonimiasis depend on the migratory stage of the worms. The worm cyst can have numerous interconnected tubular channels within its own wall and these channels have connections with the cavity and the adjacent distal bronchus.
