Expressions of inflammatory cytokines and fat factors in placentas of patients with gestational diabetes mellitus and their relationship with glucose and lipid metabolism

摘要

Objective:To study the expressions of inflammatory cytokines and fat factors in the placentas of patients with gestational diabetes mellitus and their relationship with glucose and lipid metabolism.Methods:Maternal women who delivered in obstetric department of our hospital from May 2012 to August 2015 were studied, including 45 cases of gestational diabetes mellitus patients and 45 cases of healthy women who were enrolled in the GDM group and the control group respectively. Placentas were collected to detect inflammatory factor and fatty factor contents as well as glucose and lipid metabolism indicators, and serum was collected to detect blood glucose indexes.Results:Inflammatory factors NF-kB, TNF-α, IL-1β, IL-6, IL-8, leptin, visfatin, RBP-4, Chemerin and Nesfatin-1 contents in GDM placental tissues were significantly higher than those in control group while adiponectin content was significantly lower than that in control group. FBG, FINS and HOMA-IRG of GDM patients were higher than those of the control group while HOMA-β was lower than that of control group. IRS-1, ISR-2, FATP-4, El, LPL, FABP-1, FABP-3, FABP-4 and FABP-5 contents in GDM patients’ placentas were significantly lower than those in control group. Glycolipid metabolism indexes were correlated with inflammatory factor and fat factor contents.Conclusions: Inflammatory cytokines and fat factors were abnormally highly expressed in the placentas of gestational diabetes mellitus patients, and were correlated with the indexes of glucose and lipid metabolism.
