Detection and Clinical Significance of Th17/Treg Cell-Related Factors in Patients with Gestational Diabetes Mellitus

Objective:To investigate the detection of Th17/Treg cell-related factors in patients with gestational diabetes mellitus(GDM)and its clinical significance.Methods:In this study,a retrospective cohort research method was used to collect the clinical data of 42 patients who were hospitalized in the Affiliated Hospital of Hebei University and received the diagnosis of GDM from January 2018 to December 2022,as well as 42 patients with normal pregnancies during the same period.The Th17/Treg expression levels and metabolism-related indexes in the peripheral blood of patients were detected by radioimmunoassay.Results:The relative expression of Th17 in the serum of patients in the GDM group was significantly higher than that of the control group,and the level of Treg was significantly lower than that of the control group(P<0.05);the levels of FBG,FINS,2hBG,TC,TG and HOMA-IR of the patients in the GDM group were significantly higher than that of the control group,and the level of HOMA-βwas significantly lower than that of the control group(P<0.05).Conclusion:The imbalance of the Th17/Treg cell ratio in patients with GDM may be related to their disease progression and prognosis,providing new ideas and strategies for the clinical treatment of GDM.

Relationship Between Serum microRNA-372-3p and Glucose Transporter 4 Levels and Insulin Resistance in Gestational Diabetes Mellitus

Objective:To observe the changes in insulin resistance in patients with gestational diabetes mellitus(GDM)based on the detection of serum microRNA-372-3p and glucose transporter protein 4(GLUT4)levels.Methods:We conducted a retrospective cohort study of 42 patients who were diagnosed with GDM and hospitalized in our hospital during the period from January 2017 to December 2021 and another 42 patients who had normal pregnancy during the same period by collecting their clinical data.We analyzed their serum microRNA expression profiles and miR-372-3p levels to study the relationship between GDM and insulin resistance.Results:The relative expression of miR-372-3p in the serum of patients in the GDM group was significantly higher than that of patients in the control group,but the GLUT 4 level of the GDM group was significantly lower than that of the control group(P<0.05).Compared with the control group,the GDM group had significantly higher levels of fasting blood glucose(FBG),fasting insulin(FINS),2-hour postprandial blood glucose(2h-BG),total cholesterol(TC),triglyceride(TG),and homeostatic model assessment for insulin resistance(HOMA-IR)index but significantly lower homeostasis model assessment ofβ-cell function(HOMA-β)index(P<0.05).The relative expression of miR-372-3p in serum was independently and positively correlated with HOMA-IR,while the level of GLUT4 was independently and negatively correlated with HOMA-IR(P<0.05).Conclusion:Glycosylated hemoglobin test in the early stages of pregnancy(12–13 weeks of gestation)is important to ensure the health of pregnant women and fetuses.The screening and intervention for elevated glucose in pregnant women act as a guideline for the treatment of GDM.Patients with insulin resistance and related complications such as hyperinsulinemia and hypoglycemia should be given priority.

Study on the Correlation Between SFRP-5 Expression Level, Insulin Resistance, and Glycolipid Metabolism in Gestational Diabetes Mellitus

Objective:To investigate the correlation between serum secretory frizzled-related protein 5(SFRP-5)expression levels and insulin resistance and glucolipid metabolism in patients with gestational diabetes mellitus(GDM).Methods:Baseline data were collected from 58 patients with GDM and 51 healthy controls who were admitted Affiliated Hospital of Hebei University from May 2020 to June 2022.sSTRA5 concentrations in peripheral blood of pregnant women were measured,and SFRP-5 levels in patients with different GDM types and normal controls were analyzed by logistic regression models.Results:The levels of triglyceride(TG),total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C),fasting blood glucose(FBG),fasting insulin(FINS),hemoglobin A1c(HbA1c),and homeostasis model assessment-estimated insulin resistance(HOMA-IR)were higher in the observation group than in the control group,with statistically significant differences(P<0.05),while the expression levels of high-density lipoprotein cholesterol(HDL-C)and serum SFRP-5 were lower than in the control group,with statistically significant differences(P<0.05);serum SFRP-5,TG,TC,FBG,and HOMA-IR were all risk factors for GDM(P<0.05).Conclusion:Elevated serum sSTRA5 may be involved in the regulation of insulin resistance in the body and the regulation of blood glucose in the body by affecting lipid metabolism and inflammatory response.
