Summary

Gestational diabetes mellitus (GDM) is a type of diabetes mellitus with normal glucose metabolism before pregnancy. Pregnant women with prepubertal diabetes have complicated clinical experiences, and the effects of severe disease or poor glycemic control on mothers and infants. The incidence of gestational diabetes mellitus is very high, and the short-term and long-term complications of the mother and the child are higher. Through the detection of blood samples, we can not only obtain the basic information related to the disease such as blood cells and blood biochemistry, but also learn the important information such as enzymes, antibodies and cell metabolites in the blood that are conducive to the diagnosis of the disease. More importantly, blood contains genetic material (such as genomic DNA) that can be used to screen for genes and break down molecules. Placenta tissue examination can provide important cellular, biochemical, immunological and other information. However, due to the complex etiology of gestational diabetes. Especially associated with genetic or immunological factors, in the short term often cannot make a definite diagnosis, and patients in hospital time is limited, some check items such as gene detection, placental tissue can't complete them in hospital, need to return the patient's blood, cord blood and placenta tissue, to facilitate later further screening and biology research. This study intended to establish gestational diabetes patient's blood, cord blood and placenta tissue samples library, screening is closely related to the disease biomarkers, such as disease-causing gene mutations, susceptible gene mutation and protein metabolism product, so as to clarify disease relationship between genotype and clinical phenotype, the pathogenesis of diseases, etc., and provide the basis for the diagnosis of disease and treatment optimization.

Conditions

  • Gestational Diabetes

Interventions

DIAGNOSTIC_TEST

oral glucose tolerance test

GDM should be diagnosed at any time in pregnancy if one or more of the listed criteria are met following a 75-gram glucose load: fasting plasma glucose ≥5.1 mmol/l; 1-hour plasma glucose ≥10.0mmol/l; 2-hour plasma glucose 8.5-11.0 mmol/l. Those women diagnosed with diabetes or pre-diabetes (impaired fasting glucose or impaired glucose tolerance) before pregnancy were excluded from the study.
