Abstract:
Objective:To investigate the expression of high mobility group protein 1 (HMGB1) and interleukin-17 (IL-17) in peripheral blood and membrane tissues of pregnant women with premature rupture of membranes (PROM) and its relationship with intrauterine infection.Methods:Seventy-four pregnant women with PROM from January 2019 to June 2021 were selected as the study group, and 58 healthy pregnant women at the corresponding period were selected as the healthy control group. The levels of HMGB1 and IL-17 in peripheral blood and membrane tissues and serum CD 8+ were compared between the two groups. The pregnant women with PROM were divided into the chorioamnionitis group, subclinical chorioamnionitis group and normal group according to their intrauterine infection, the expression levels of HMGB1 and IL-17 in peripheral blood and membrane tissues of patients with different infection degrees were compared, and the correlation with the severity of intrauterine infection were analyzed. Results:The levels of peripheral blood HMGB1, membrane tissues HMGB1, peripheral blood IL-17, membrane tissues IL-17 and serum CD 8+ in the study group were higher than those in the control group: (28.34 ± 5.16) μg/L vs. (22.51 ± 4.09) μg/L, 0.79 ± 0.12 vs. 0.34 ± 0.05, (13.05 ± 2.57) ng/L vs. (8.16 ± 1.38) ng/L, 0.37 ± 0.06 vs. 0.12 ± 0.02, 0.386 ± 0.052 vs. 0.252 ± 0.044, there were statistical differences ( P<0.05). The levels of HMGB1 and IL-17 in peripheral blood and membrane tissues and serum CD 8+ were increased with the severity of severity of intrauterine infection ( P<0.05). The results of Spearman correlation analysis showed that the level of peripheral blood HMGB1, membrane tissues HMGB1 and IL-17 had positively correlated with the severity of intrauterine infection ( r = 0.336, 0.316, 0.311, P<0.05). The results of receiver operating characteristic curve analysis showed that combined detection of HMGB1 and IL-17 levels in peripheral blood and membrane tissues and serum CD 8+ levels in evaluating the severity of intrauterine infection had higher area under the curve than that of each index alone ( P<0.05). Conclusions:Pregnant women with PROM have abnormal HMGB1 and IL-17 levels in peripheral blood and membrane tissues, and HMGB1 levels in peripheral blood and mRNA expressions of HMGB1 and IL-17 in membrane tissues are positively correlated with the severity of intrauterine infection, which has evaluation value for the severity of the disease.
