目的 通过对85例颈椎病影像学资料进行分析，探讨颈椎病的影像学特征及其X线片、CT、MRI及MRA检查方法的选择原则，以便临床上对不同类型以及不同程度的颈椎病选择合适的诊断技术。 方法 2005年6月-2009年7月，85例均行颈椎标准X线片、CT、MRI及MRA检查，对其影像学资料进行分析。 结果 颈椎病以椎体及小关节增生、生理曲度改变、椎间隙变窄和局部失稳为常见X线表现，X线片、CT、MRI及MRA对颈椎病的诊断有不同的优点及限度。 结论 X线片为首选检查方法，绝大部分可明确诊断，特殊情况加做CT、MRI或MRA检查。
Objective To evaluate the control status and knowledge level about disease in asthmatic patients in region level cities of Shaanxi province for effect appraisal of patient education. Methods Eight hospitals were selected from six region level cities, where questionnaire survey was completed in out-patients with asthma ( ≥14 years old) . Results A total of 523 patients completed the questionnaire with a ratio of male to female of 1∶1. 14, and an average age of ( 44. 3 ±15. 5) years old.

The average score was 17. 88 ±4. 43 by asthma control test ( ACT) . The first three medicines used daily were ICS ( 26. 6% ) , sustained-release theophyline ( 25. 2% )and combination ICS/ long-acting β2 -agonists ( 21. 8% ) . 12. 6% had no medicine and 5. 2% used nonorthodox medicines. 68. 6% patients had omen before exacerbation, and those were sneezing, chest distress and cough. 73. 6% knew asthma is a disease of airway inflammation, and 33. 3% selected ICS as the leader medicine. Only 32. 1% attended the lecture about asthma in hospitals and 85. 0% longed for such education. Conclusions The control status and knowledge level about disease in asthmatic patients in cities still need to be improved in Shaanxi province, and too much work need to be done in order to realize the total control in all patients.
