| 目的 观察动态X线胸片定量分析平静呼吸下慢性阻塞性肺疾病（COPD）患者横膈运动的价值。方法 对96例COPD患者（COPD组）和50名健康对照者（对照组）行平静呼吸下动态X线胸片检查，经后处理获得横膈运动幅度、速度及时间；记录2组肺功能检查结果，比较组间动态X线胸片及肺功能参数值差异，分析COPD横膈运动参数与肺功能参数的相关性。结果 平静呼吸下COPD组左、右侧横膈运动幅度[（18.63±7.45）mm、（15.64±5.98）mm]均大于对照组[（14.69±5.40）mm、（13.13±4.84）mm，P均<0.05]；吸气时和呼气时COPD组左侧横膈运动速度18.79（15.67，22.67）mm/s、16.00（12.36，21.23）mm/s，右侧为17.00（12.71，19.73）mm/s、13.75（9.50，16.83）mm/s；对照组左侧为15.33（13.96，17.71）mm/s、11.42（9.63，16.00）mm/s，右侧为（14.91±4.38）mm/s、（10.66±3.66）mm/s（P均<0.05）。2组肺功能检查结果差异均有统计学意义（P均<0.01）。COPD组肺功能参数与动态胸片检查各参数均无明显相关（P均>0.05）。结论 动态X线胸片可定量分析COPD患者横膈运动，有望为临床精准评估COPD提供新的手段。 |

| Objective To explore the value of evaluation of the diaphragmatic motion in chronic obstructive pulmonary disease (COPD) patients with dynamic X-ray chest radiography under calm breathing. Methods Dynamic X-ray chest radiographs were performed in 96 COPD patients (COPD group) and 50 healthy controls (control group) under calm breathing. The range, speed and time of the diaphragmtic motion were obtained and analyzed. Results of lung function tests of 2 groups were recorded. Dynamic X-ray chest radiographs and pulmonary function parameters were compared between 2 groups, and the correlations of diaphragmatic motion parameters and lung function parameters were analyzed, respectively. Results The left and right side diaphragmatic motion amplitude in COPD group ([18.63±7.45]mm,[15.64±5.98]mm) were larger than those in control group ([14.69±5.40]mm,[13.13±4.84]mm, both P<0.05). During inspiratory phase and expiratory phase, the motion speeds of left diaphragm in COPD group were 18.79 (15.67, 22.67) mm/s and 16.00 (12.36, 21.23) mm/s, the right side were 17.00 (12.71, 19.73) mm/s and 13.75 (9.50, 16.83) mm/s, respectively, while in control group of the left side were 15.33 (13.96, 17.71) mm/s and 11.42 (9.63, 16.00) mm/s, of the right side were (14.91±4.38) mm/s and (10.66±3.66) mm/s, respectively (all P<0.05). There were statistical differences of lung function between 2 groups (all P<0.01),but the pulmonary function parameters were not significantly correlated with dynamic chest radiograph examination parameters in COPD group (all P>0.05). Conclusion Using dynamic X-ray chest radiograph could quantitatively analyze the diaphragmatic movement of COPD patients, providing a new examination method for accurate clinical evaluation of COPD. |
