急性加重期的慢性阻塞性肺疾病(AECOPD)会导致患者住院率以及死亡率增加~([1]),国外有学者通过对慢性阻塞性肺病急性加重期(AECOPD)患者的研究发现,中重度COPD患者外周血中CD34~+细胞数量明显减少~([2]),并且外周循环血中CD34~+细胞数量的减少能显著地加大心血管系统疾病的发病风险~([3])。本实验主要观察急性加重期慢性阻塞性肺疾病(AECOPD)患者外周血中CD34~+细胞的数量的变化作为评价
Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) will lead to increased hospitalization and mortality in patients with ~ ([1]), foreign scholars through the study of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) found that moderate to severe The number of CD34 + cells in the peripheral blood of patients with COPD is significantly reduced (2), and the reduction in the number of CD34 + cells in the peripheral blood can significantly increase the risk of cardiovascular disease (3). This experiment is mainly observed in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) changes in the number of CD34 ~ + cells in peripheral blood as an assessment
