Epidemiological studies have indicated that exposure to hexavalent chromium (Cr(VI)) is associated with increased morbidity in the population. Resveratrol (Res) is a polyphenolic compound known for its role in mitigating oxidative stress and inflammation. In this study, we investigated the effects of resveratrol on Cr(VI)-induced disorders of glycolipid metabolism and elucidated its mechanisms. Male C57BL/6 mice were exposed to resveratrol and Cr(VI) for 45 days. Cr(VI) exposure led to elevated blood glucose levels, impaired glucose tolerance and insulin resistance, oxidative and inflammatory responses, and alterations in glycolipid metabolism molecules such as PCK1 and SREBP1, along with inhibition of HNF1b and GPX1. Resveratrol pretreatment increased the expression of HNF1b and GPX1, reduced oxidative and inflammatory responses, and ultimately ameliorated Cr(VI)-induced glycolipid metabolism disorders. These findings suggest potential new targets for the prevention and treatment of dysglycolipidosis.

Department of Endocrinology, The First Affiliated Hospital, Fujian Medical University, Fuzhou, 350005, China.
Objective: This study aimed to determine whether a relationship exist between pre-therapy 25-hydroxyvitamin D levels and the remission/negative conversion rates of thyrotropin receptor antibody (TRAB) during treatment in patients with newly diagnosed Graves' disease (GD).
Methods: 171 patients were included from the Endocrinology Department of the First Affiliated Hospital of Fujian Medical University in March 2013 to April 2016. Ninety-five patients of them were diagnosed at our hospital but transferred to local hospitals for treatment.

Monogalactosyldiacylglycerol (MGDG), as the primary lipid component of thylakoid membranes, has a significant part in plant growth and stress response. The current study employed two transgenic wheat lines (MG1516 and MG1314) overexpressing the MGDG synthase gene (TaMGD) and wild-type cv "JW1" to explore the function of TaMGD in response to high temperature stress during the anthesis stage of wheat. Under high-temperature stress, the overexpressed wheat lines exhibited higher grain weight, increased antioxidant enzyme activity, and lower HO and malondialdehyde contents in leaves.

Objectives: Spingosine-1-phosphate (S1P) and ceramides are bioactive sphingolipids that influence cancer cell fate. Anti-ceramide antibodies might inhibit the effects of ceramide. The aim of this study was to assess the potential role of circulating S1P and anti-ceramide antibody as biomarkers in non-small cell lung cancer (NSCLC).
