				        	Objective To investigate predictive value of serum levels of long noncoding RNA differentiation antagonizes non-protein coding RNA(LncRNA DANCR)and microRNA(miR)-33a-5p in patients with gestational diabetes mellitus(GDM)on pregnancy outcome.Methods A total of 154 GDM patients who underwent prenatal examination and delivery in the Fourth People's Hospital of Hengshui from August 2021 to February 2023 were collected as the GDM group,and these patients were grouped into a good outcome group of 115 cases and an adverse outcome group of 39 cases based on pregnancy outcomes.Meantime,149 healthy pregnant women with normal glucose tolerance test for 24 weeks were collected as the control group.Realtime fluorescence quantitative PCR(qRT-PCR)method was applied to detect serum LncRNA DANCR and miR-33a-5p levels,and receiver operating characteristic(ROC)curve was used to analyze the value of serum LncRNA DANCR and miR-33a-5p in predicting adverse pregnancy outcomes in GDM patients.Pearson correlation was applied to analyze the correlation among serum LncRNA DANCR,miR-33a-5p,fasting bloodglucos(FBG),fasting insulin(FINS),and homeostasis model assessment of insulin resistance(HOMA-IR)in patients with GDM adverse pregnancy outcomes.Logistic regression was used to analyze the influencing factors of adverse pregnancy outcomes in GDM patients.Results The serum LncRNA DANCR level(0.69±0.15)in the GDM group was lower than that in the control group(1.01±0.22),while the level of miR-33a-5p(1.59±0.40)and the total incidence of adverse pregnancy outcomes(25.34%)were higher than those in the control group(1.02±0.23,5.36%),with significant differences(t/x2=14.835,15.140,23.011,all P<0.05).The serum LncRNADANCR level(0.50±0.14)in the adverse outcome group was lower than that in the good outcome group(0.75±0.18),while miR-33a-5p(2.00±0.58),FBG(8.97±0.66mmol/L),FINS(18.63±1.31pmol/ml)and HOMA-IR(7.42±0.98)were higher than those in the good outcome group(1.45±0.26,8.01±0.59mmol/L,14.32±1.29pmol/ml,5.10±0.86),the differences were statistically significant(t=7.895~17.961,all P<0.05).The areas under curve(AUC)of predicting adverse pregnancy outcomes in GDM patients with LncRNA DANCR and miR-33a-5p alone and in combination were 0.820,0.819 and 0.897,respectively.For patients with GDM adverse pregnancy outcomes,serum LncRNA DANCR was negatively correlated with FBG,FINS and HOMAIR(r=-0.498,-0.513,-0.509,allP<0.05),while miR-33a-5p was positively correlated with FBG,FINS and HOMA-IR(r=0.517,0.494,0.507,all P<0.05).LncRNA DANCR was a protective factor that affected adverse pregnancy outcomes in GDM patients(OR=0.804,95%CI:0.693~0.933,P=0.004);while miR-33a-5p was a risk factor for adverse pregnancy outcomes in GDM patients(OR=2.747,95%CI:1.444~5.225,P=0.002).Conclusion LncRNA DANCR was decreased and miR-33a-5p was increased in GDM patients with adverse pregnancy outcomes,indicating both may be influencing factors for adverse pregnancy outcomes.
