Abstract:Objective To investigate the effect of glibenclamide-assisted “double C” regimen on the expression of serum FABP4 and pregnancy-associated plasma protein A (PAPP-A) in patients with gestational diabetes mellitus, and to provide reference for the clinical treatment of gestational diabetes mellitus. Methods A total of 120 elderly gestational diabetes patients admitted to our hospital from January 2015 to December 2017 were enrolled. The randomized digital table method was used to divide patients into study group and control group, 60 cases each. The control group was treated with “double C” regimen, and the study group was treated with glibenclamide on the basis of the control group. The blood glucose control, neonatal and maternal indicators were compared between the two groups after 12 weeks of treatment, and serum FABPs and PAPP-A expression levels were detected before and after treatment. Results The difference of HbAlc, FPG, 2hPG, blood glucose fluctuation, blood glucose compliance time and insulin mean between the two groups was statistically significant, and the study group was higher than the control group (P < 0.05); the difference between the two groups of patients before and after treatment HbAlc, FPG, 2hPG, blood glucose fluctuation amplitude, blood glucose compliance time and insulin dosage were statistically significant (P < 0.05), and before treatment is higher than after treatment; the incidence of gestational hypertension, premature rupture of membranes, prolonged labor, preterm infants, hyperbilirubinemia and total newborn adverse events in the study group was significantly lower than that in the control group (P < 0.05). After treatment, the serum FABP4 level of the study group significantly lower than the control group, pregnancy-associated plasma protein A MoM level was significantly higher than the control group, both were statistically significant (P < 0.05). There were 2 cases and 3 cases of hypoglycemia in the study group and the control group, respectively, and the incidence of adverse hair loss was not statistically significant (P < 0.05). Conclusion Glibenclamide combined with “double C” regimen can effectively improve blood glucose levels and pregnancy outcomes in GDM patients, and can improve insulin resistance by lowering serum FABP4 levels and increasing PAPP-A levels, which is safe and worthy of clinical application.
