In the mild group, there were 10 males and 8 females, aged (56.80±8.18) years; in the moderate group, there were 17 males and 13 females, aged (57.07±8.35) years; in the severe group, there were 21 males and 17 females, aged (57.22±8.43) years. The forced vital capacity (FVC), forced expiratory volume in the first second (FEVn 1), FEVn 1/FVC, maximum ventilation (MVV), diffusing capacity for carbon monoxide (DLco), procalcitonin (PCT), C reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-2 (IL-2), interleukin-6 (IL-6), interleukin-8 (IL-8) levels were compared among the three groups. χn 2 test was used for the count data; one-way ANOVA was used for the measurement data, LSD method was used for pairwise comparison, and Pearson correlation anlysis was used to analyze the correlations between inflammatory indexes and lung function in ARDS patients.n Results:CRP [(32.55±6.20) mg/L vs. (21.40±5.18) mg/L], TNF-α [(72.45±14.22) ng/L vs. (56.75±11.30) ng/L], IL-2 [(451.70±49.35) ng/L vs. (382.30±36.40) ng/L], IL-6 [(176.35±20.44) ng/L vs. (142.60±18.45) ng/L], and IL-8 levels [(265.70±29.40) ng/L vs. (185.35±21.60) ng/L] in the moderate group were higher than those in the mild group; CRP [(43.75±7.28) mg/L vs. (21.40±5.18) mg/L], PCT [(9.70±2.45) μg/L vs. (7.65±1.89) μg/L], TNF-α [(89.80±15.60) ng/L vs. (56.75±11.30) ng/L], IL-2 [(524.85±56.75) ng/L vs. (382.30±36.40) ng/L], IL-6 [(214.35±22.74) ng/L vs. (142.60±18.45) ng/L], and IL-8 levels [(368.9±41.35) ng/L vs. (185.35±21.60) ng/L] in the severe group were higher than those in the mild group; CRP, TNF-α, IL-2, IL-6, and IL-8 levels in the severe group were higher than those in the moderate group; there were statistically significant differences (alln P<0.05). FVC [(1.74±0.27) L vs. (1.98±0.31) L], FEVn 1 [(1.33±0.26) L vs. (1.56±0.28) L], DLco [(64.30±6.82)% vs. (68.54±7.26)%] in the moderate group were lower than those in the mild group; FVC [(1.55±0.21) L vs. (1.98±0.31) L], FEVn 1 [(1.12±0.19) L vs. (1.56±0.28) L], FEVn 1/FVC [(71.58±4.86)% vs. (78.58±5.46)%], MVV [(66.80±8.70) L vs. (76.50±10.68) L], and DLco [(61.25±6.35)% vs. (68.54±7.26)%] in the severe group were lower than those in the mild group; FVC, FEVn 1, FEVn 1/FVC, and MVV of the severe group were lower than those of the moderate group; there were statistically significant differences (all n P<0.05). Pearson correlation analysis showed that CRP, PCT, TNF-α, IL-2, IL-6, and IL-8 were significantly negatively correlated with FVC, FEVn 1, FEVn 1/FVC, MVV, and DLco (all n P<0.05).n Conclusions:The CRP, PCT, TNF-α, IL-2, IL-6, and IL-8 of ARDS patients are closely correlated with FVC, FEVn 1, FEVn 1/FVC, MVV, and DLco. The monitoring on inflammatory indexes should be strengthened to prevent the deterioration of lung function in ARDS patients.n
