| 目的 观察慢性阻塞性肺疾病急性加重期(AECOPD)患者胸部CT定量参数与血嗜酸性粒细胞(EOS)水平的相关性。方法 回顾性分析162例EOS增多型AECOPD患者胸部CT,根据血EOS绝对计数将其分为低EOS组(n=105)及高EOS组(n=57);比较组间CT定量参数,包括全肺支气管数量及血管体积,全肺、左/右肺及各肺叶低密度衰减区容积占全肺容积百分比(LAA%),以及第3~8级支气管管腔内径(LD)、管壁厚度(WT)、管壁面积(WA)及WA占支气管断面总面积百分比(WA%);采用Spearman相关分析观察CT定量参数与血EOS水平的相关性。结果 低EOS组全肺、左/右肺及各肺叶LAA%,以及右肺上叶LD第4级、右肺中叶WT第5级、右肺上叶WA第4级、右肺中叶WA第5级及左肺下叶WA第3级均高于高EOS组(P均＜0.05)。除右肺上叶LD第4级外,上述组间差异有统计学意义的CT定量参数均与血EOS水平呈弱负相关(r=－0.335~－0.164,P均＜0.05)。结论 AECOPD 患者胸部CT定量参数与血EOS水平相关;LAA%及部分WT、WA均与血EOS水平呈弱负相关。 |

| Objective To observe the correlations of chest CT quantitative parameters in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with blood eosinophil (EOS) level. Methods Chest CT data of 162 AECOPD patients with elevated eosinophils were retrospectively analyzed. The patients were divided into low EOS group (n=105) and high EOS group (n=57) according to the absolute counting of blood EOS. The quantitative CT parameters, including the number of whole lung bronchi and the volume of blood vessels, low-attenuation area percentage (LAA%) of whole lung, of left/right lung and each lobe of lung, as well as the luminal diameter (LD), wall thickness (WT), wall area (WA) and WA percentage of total bronchial cross-section (WA%) of grade 3 to 8 bronchi were compared between groups.Spearman correlations were performed to analyze the correlations of quantitative CT parameters with blood EOS level. Results LAA% of the whole lung, of the left/right lung and each lobe of lung, as well as of the upper lobe of right lung LDgrade 4, middle lobe of right lung WTgrade 5, upper lobe of right lung WAgrade 4, middle lobe of right lung WAgrade 5 and lower lobe of left lung WAgrade 3 in low EOS group were all higher than those in high EOS group (all P＜0.05). Except for the upper lobe of right lung LDgrade 4, the above quantitative CT indexes being significant different between groups were all weakly and negatively correlated with blood EOS level (r=－0.335 to －0.164, all P＜0.05). Conclusion Chest CT quantitative parameters of AECOPD patients were correlated with blood EOS level, among which LAA%, a part of WT and WA were all weakly negatively correlated with blood EOS level. |
