miR-34b-3p protects against acute kidney injury in sepsis mice via targeting ubiquitin-like protein 4A.

MicroRNAs (miRNAs) have been reported as a diagnostic markers for sepsis, and miRNAs have also been found to play a regulatory role in sepsis-induced acute kidney injury (AKI). However, the regulatory effect and mechanism of miR-34b-3p on AKI remains elusive. First, sepsis mice with AKI was established via cecal ligation puncture (CLP), and verified through hematoxylin-eosin staining, determination of tumor necrosis factor-α (TNF-α), interleukin (IL)-6/1β and serum levels of alanine aminotransferase (ALT) and blood urea nitrogen (BUN).

Effect of a short-term vitamin E supplementation on oxidative stress in infertile PCOS women under ovulation induction: a retrospective cohort study.

Background: Vitamin E, which is critically important in the whole process of reproduction, can antagonize the oxidative stress caused by the oxygen free radicals and antioxidant imbalance and regulate normal physiological function of the reproductive system. The effect of short-term supplementation of vitamin E on outcomes of infertile women with polycystic ovary syndrome (PCOS) when they underwent ovulation induction with clomiphene citrate (CC) and human menopausal gonadotropin (HMG) remains unknown.

Methods: This was a retrospective cohort clinical trial from October 2015 to April 2017.
