Abstract:
Objective:To explore the relationship between serum soluble myeloid cell trigger receptor-1(sTREM-1)messenger RNA(mRNA),high mobility group protein B1(HMGB1)mRNA levels and intestinal flora and the occurrence of preterm premature rupture of membranes(PPROM)in gestational diabetes mellitus(GDM)patients.Methods:98 GDM pregnant women with GDM combined with PPROM who underwent regular prenatal check ups and delivered at the First Hospital Affiliated to Hebei North University from June 2022 to May 2024 were selected as the GDM combined with PPROM group,102 GDM pregnant women without PPROM were selected as the GDM without PPROM group,and 108 normal pregnant women were selected as the control group.Intestinal flora,serum sTREM-1 mRNA,HMGB1 mRNA levels of the three groups of pregnant women were collected and compared;the correlation between serum sTREM-1 mRNA and HMGB1 mRNA levels and intestinal flora in GDM pregnant women,the factors affecting the occurrence of PPROM in pregnant women with GDM,and the predictive value of serum sTREM-1 mRNA and HMGB1 mRNA in the occurrence of PPROM in GDM pregnant women were analyzed.Results:Compared with control group,colony number of Enterococcus,Enterobacter,Bacteroides and Fusobacterium were significantly increased in GDM without PPROM group and GDM combined with PPROM group(P＜0.05),the colony number of Bifidobacterium and Lactobacillus was significantly de-creased(P＜0.05).The gestational age at delivery of GDM combined with PPROM group was significantly lower than that of control group and GDM without PPROM group(P＜0.05).Compared with GDM without PPROM group,the colony number of Bifidobacterium and Lactobacillus were significantly decreased(P＜0.05),colony number of Enterococcus,Enterobacter,Bacteroides and Fusobacterium were significantly increased in GDM com-bined with PPROM group(P＜0.05).The serum levels of sTREM-1 mRNA and HMGB1 mRNA in control group,GDM without PPROM group,GDM combined with PPROM group were increased sequentially(P＜0.05).Serum sTREM-1 mRNA was positively correlated with HMGB1 mRNA in GDM pregnant women(r＞0,P＜0.05);serum sTREM-1 mRNA and HMGB1 mRNA were positively correlated with the colony numbers of Enterococcus,Enter-obacter,Bacteroides and Fusobacterium(r＞0,P＜0.05),and negatively correlated with the colony numbers of Bifidobacterium and Lactobacillus(r＜0,P＜0.05).Enterococcus,Enterobacter,Bacteroides,Fusobacterium,sTREM-1 mRNA and HMGB1 mRNA were independent risk factors for PPROM in GDM pregnant women(OR＞1,P＜0.05),while Bifidobacterium and Lactobacillus were independent protective factors for PPROM in GDM pregnant women(OR＜1,P＜0.05).The area under curve(AUC)of predicting PPROM in GDM pregnant women by combining serum sTREM-1 mRNA and HMGB1 mRNA(0.922)was higher than the AUC predicted by serum sTREM-1 mRNA and HMGB1 mRNA alone(0.829,0.841)(P＜0.05).Conclusions:Serum sTREM-1 mRNA and HMGB1 mRNA were highly expressed in GDM pregnant women,and the increase trend of serum both was more obvious in GDM pregnant women with PPROM,both of which were related to intestinal flora imbalance and the occurrence of PPROM.The combination of sTREM-1 mRNA and HMGB1 mRNA has high efficacy in predicting the occurrence of PPROM.
