Objective: To study the effects of serum Fractalkine on vascular remodeling and oxidative stress activation in patients with COPD complicated by pulmonary heart disease. Methods: Patients who were hospitalized in Chongqing Armed Corps Police Hospital due to COPD between June 2014 and April 2017 were selected, the patients with COPD alone were included in COPD group, and the patients with COPD complicated by pulmonary heart disease were included in COPD+PHD group; healthy volunteers who underwent physical examination during the same period were selected as the control group of the study. The serum was collected to determine the contents of Fractalkine, vascular remodeling indexes and oxidative stress indexes. Results: Serum Fractalkine, ANG-2, MMP2, MMP9, VEGF, FGF2, Nogo-B, ET-1 and MDA contents of COPD+PHD group and COPD group were higher than those of control group whereas T-AOC contents were lower than that of control group; serum Fractalkine, ANG-2, MMP2, MMP9, VEGF, FGF2, Nogo-B, ET-1 and MDA contents of COPD+PHD group were higher than those of COPD group whereas T-AOC content was lower than that of COPD group. Serum ANG-2, MMP2, MMP9, VEGF, FGF2, Nogo-B, ET-1 and MDA contents of COPD+PHD group of patients with high Fractalkine content were significantly higher than those of COPD+PHD group of patients with low Fractalkine content whereas T-AOC content was lower than that of COPD+PHD group of patients with low Fractalkine content. Conclusion: The increase of serum Fractalkine in patients with COPD complicated by pulmonary heart disease can aggravate the vascular remodeling and promote the oxidative stress activation.
