Detective value of placental tissue resistin, human lipid carrier protein and blood glucose and lipid metabolism in gdm patients complicated with preeclampsia / 中华内分泌外科杂志

ABSTRACT

Objective:To analyze the detective value of placental tissue resistin, human lipid carrier protein (LCN) and blood glucose and lipid metabolism in pregnant women with gestational diabetes mellitus (GDM) complicated with preeclampsia (PE) , providing guidance for the early treatment of GDM complicated with preeclampsia.Methods:96 pregnant women with GDM complicated with PE (GDM-PE group) admitted to Yantai Yantaishan Hospital from Jan. 2017 to Jan. 2020 were selected and retrospectively studied. According to the ratio of 21, the pure GDM pregnant women (GDM group) and 48 normal pregnant women (the control group) were selected. The placenta tissue resistin and LCN levels were determined by immunohistochemistry. Blood samples were collected to determine the glucose and lipid metabolism. The pregnancy outcomes of each group were compared and the relationship between resistin, LCN, glucose and lipid metabolism and GDM complicated with PE was analyzed.Results:Fasting blood-glucose (FBG) was (4.57±0.66) mmol/L in GDM group and (5.23±0.61) mmol/L in GMD-PE group. FINS (11.97±1.5) mIU/L, (15.12±3.52) mIU/L were higher than those of control group (4.11±0.23) mmol/L, (6.75±1.34) mIU/L ( P<0.05) . FBG, FINS, glycosylated hemoglobin (HbA1c) in GDM-PE group were higher than those in GDM group. TC) (6.71±1.63) mmol/L, triglyceride, TG (6.59±0.87) mmol/L was higher than that of control group (5.87±0.73) mmol/L, (4.57±0.59) mmol/L and GDM group (6.02±1.55) mmol/L, (4.71±0.63) mmol/L ( P<0.05) . high density lipoprotein cholesterol (HDL-C) (1.21±0.34) was lower than that of control group (1.54±0.39) and GDM group (1.55±0.43) ( P<0.05) . The positive rates of resistin 85.42%, 60.42%, LCN 81.25%, 56.25% in GDM-PE group and GDM group were higher than those in control group 39.58%, 31.25% ( χ2=32.096, 4.167; 34.975, 6.095, both P<0.05) . The positive rates of resistin and LCN in GDM-PE group were higher than those in GDM group ( χ2=11.322, 11.257, both P<0.01) . The gestational age of delivery in GDM-PE group was (37.11±2.06) weeks earlier than that in GDM group (38.21±1.75) weeks and control group (38.36±1.42) weeks ( F=9.836, P<0.05) . The birth weight of neonates (2 905.45±356.79) g was lower than that of control group (3 321.52±366.46) g and GDM group (3 425.14±269.87) g ( F=46.606, P<0.05) . Postpartum blood loss (415.34±126.75) ml was significantly higher than that of GDM group (338.65±105.63) ml and control group (298.42±75.26) ml ( F=19.932, P<0.05) . The preterm birth rate of 20.83% was higher than that of the GDM group (8.33%) and the control group (4.17%) ( χ2=9.075, P<0.05) . The postpartum blood loss of the GDM group was higher than that of the control group ( t=-2.148, P<0.05) . The incidences of fetal distress, premature rupture of membranes, fetal growth restriction and postpartum hemorrhage in GDM-PE group were higher than those in control group ( χ2=4.571, 6.867, 5.941, 5.123, P<0.05) . The protein expressions of resistin and LCN in placenta of pregnant women with GDM-PE were positively correlated with FBG, FINS, TC and TG ( r=0.517, 0.463, 0.559, 0.521, 0.485, 0.497, 0.557, 0.571, P<0.05) . Was negatively correlated with HDL-C ( r=-0.317, -0.357, P<0.05) . Conclusions:The positive rate of resistin and LCN in the placenta tissue of pregnant women with GDM complicated with PE is higher than that of GDM and normal pregnant women, their disorder of glucose and lipid metabolism is more obvious, and the incidence of adverse maternal and infant outcomes is higher. It is speculated that resistin and LCN may synergistically affect the metabolism of glucose and lipids causing adverse pregnancy outcomes in GDM complicated with PE.
