PTX3 and gestational diabetes: This article investigated the changes of PTX3 and hs-CRP levels in pregnant women by detecting serum PTX3, hs-CRP, and related biochemical indicators in pregnant women at different stages (early, middle and late), and analyzed the correlation between PTX3/hs-CRP and GDM, aiming to explore the early predictive value of inflammatory markers (PTX3 and hs-CRP) for the pathogenesis of GDM.
