Dendrobium mixture improves gestational diabetes mellitus through regulating Nrf2/HO1 signaling pathway.

Background: Gestational diabetes mellitus (GDM) is characterized by insulin resistance during pregnancy, and it is always combined with serious complications. Dendrobium mixture (DMix) is a kind of traditional Chinese medicine, and it has been proved to be an effective treatment for diabetes. However, the regulatory role of DMix in GDM remains elusive.

Expression and clinical significance of LXRα and SREBP-1c in placentas of preeclampsia.

Objective: To evaluate the expression and correlations of liver X receptor alpha (LXRa) and its target gene sterol regulatory element-binding protein-1c (SREBP-1c) in placentas of preeclampsia (PE) and their significance in PE.

Methods: Pregnancies were divided into two groups, 60 cases (29 cases of mild and 31 cases of severe) of PE group and 56 cases of normal group. The level of mRNA and protein of LXRa and SREBP-1c were analyzed by reverse transcription-polymerase chain reaction (RTPCR) and immunohistochemistry (IHC) in the placentas.
