Significance of NLR， PLR， RDW Combined with IL-6 in Poor Prognosis of AECOPD and Its Predictive Effcacy Analysis/CHEN Zhaodi， YOU Jianhua， XIE Wenqi. //Medical Innovation of China， 2025， 22(12)： 144-148

    [Abstract]Objective： To analyze the predictive value of neutrophil-to-lymphocyte ratio (NLR)， plateletto-lymphocyte ratio (PLR)，red cell volume distribution width (RDW)combined with interleukin-6 (IL-6)in poor prognosis of acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Method： A total of 50 patients with AECOPD treated inthe FirstPeople's Hospital of Fuzhou from June 2022 to June 2024 were selected as the studyobjects.Thevenous blood samplesofallpatients werecollected，thelevelsofneutrophil，lymphocyte， platelet，RDW and IL-6 were detected， NLR and PLR were calculated， andthe predictive valueof NLR，PLR，RDW combined with IL-6 in the poor prognosis of AECOPD were analyzed. Result：Among the 50 patients with AECOPD， 39 survived， with a survival rate of 78.00% . Compared with the death group， the levels of NLR， PLR， RDW， IL-6 and proportionof smoking history in the survival group were lower ......
