目的 研究颈源性头痛患者颈椎X线中C2~C7棘突偏歪和椎体滑脱情况,总结其中存在的规律,为治疗颈源性头痛提供影像学理论支持。方法 选取颈源性头痛患者96例,观察并记录每位患者颈椎X线片中C2~C7棘突偏歪和椎体滑脱情况。用统计软件分别对棘突偏歪和椎体滑脱数据进行分析。结果 颈源性头痛患者较常出现棘突偏歪,右侧偏歪明显多于左侧偏歪。其中C2棘突偏歪最常见,出现比例为66.7%。C2棘突偏歪率与C3~C7分别进行χ²检验,其中C5、C6与C2均有显著差异。C3、C4、C7与C2均无显著差异。椎体滑脱亦常出现于颈源性头痛患者,其中C7椎体向前Ⅰ度滑脱最常见,出现比例为50.0%。C7椎体向前Ⅰ度滑脱率与C2~C6分别进行χ²检验,其结果均有显著差异。结论 C2棘突偏歪和C7椎体向前Ⅰ度滑脱较常出现于颈源性头痛患者。在治疗颈源性头痛患者时,与C2和C7相关的软组织损伤和关节紊乱应引起重点关注。

Objective To study the skew of C2~C7 spinous process deviation and spondylolisthesis in cervical spine X-ray of patients with cervical headache,and summarize the existing rules,so as to provide imaging theoretical support for the treatment of cervical headache．Methods The C2~C7 spinous process distortion and spondylolisthesis in cervical radiographs of 96 patients with cervical headache were observed,recorded and analyzed．Results Skew of spinous process was more common in patients with cervicogenic headache,and skew of right side was more obvious than skew of left side．C2 spinous process was the most common,and the proportion of occurrence was 66.7%．The skew rate of C2 spinous process were compared with that of C3~C7 by χ² test．There were significant differences between C5,C6 and C2．There were no significant difference between C3,C4,C7 and C2．Spondylolisthesis was commonly seen in patients with cervicogenous headache,and I degree spondylolisthesis was most commonly seen in C7,and the proportion of occurrence was 50.0%．There were significant differences between the anterior Ⅰ degree slip rate of C7 vertebrae and that of C2~C6 vertebrae by χ² test．Conclusions C2 spinous process and C7 spondylolisthesis I are more commonly seen in patients with cervicogenic headache．Soft tissue injuries and joint disorders associated with C2 and C7 should be paid more attention in the treatment of patients with cervicogenic headache．

目的 分析2014年482例广州登革热患者的X线胸片特点,探讨X线胸片对登革热患者的临床诊断价值。方法 选取广州市第一人民医院2014年收治的482例登革热患者作为研究对象,观察分析其X线胸片检查结果的特征。结果 登革热患者X线胸片影像学特点以非特异性的肺纹理增多增粗和斑片渗出灶为主要表现,另有胸膜增厚、胸腔积液和间质性改变。结论 X线胸片检查可以经济、便捷地了解登革热患者的肺部改变,为临床诊断和治疗提供帮助。

Objective To analyze the characteristics of chest X-ray in 482 cases of dengue fever in Guangzhou 2014, and to discuss the diagnostic value of chest X-ray in dengue fever patients. Methods 482 patients of dengue fever patients admitted in Guangzhou First People's Hospital were selected as the research object. The characteristics of the chest X-ray were observed and analyzed. Results The characteristics of chest X-ray images included lung markings thickening increased, exudation, and might lead to pleural thickening, effusion and interstitial change. Conclusion Chest X-ray was a convenient examination for dengue fever patients which had an important diagnostic and therapeutic value.
