  • Hesperidin Inhibits High Mobility Group Protein B1 Releasing and Attenuates Acetaminophen-induced Hepatitis in Mice

    ObjectiveTo investigate the protective effect of hesperdin (HDN) on acetaminophen (APAP)-induced acute liver injury in mice. MethodsForty-eight male BALB/c mice were randomly divided into six groups:normal group, model group, HDN (the doses respectively were 500, 250 and 125 mg/kg) group and bifendate group. The HDN group was separately intragastrically given different doses of hesperidin for ten days. The bifendate group was given bifendate. Acute liver injury was induced by injecting APAP (150 mg/kg) in all mice except those in the normal group. After 16 hours, all mice were sacrificed. Serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured. The contents of glutathione (GSH) and malondialdehyde (MDA) in liver homogenates were determined. Pathological changes in hepatic tissue were observed under an optical microscope. The expression of high mobility group protein B1 (HMGB1) in hepatic tissue was measured by reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry. ResultsHDN could significantly reduce serum ALT, AST, liver homogenate MDA levels, improve liver tissue GSH activity and the liver injury was lightened. By RT-PCR and immunohistochemistry, it showed that HDN could inhibit the releasing and expression of HMGB1. ConclusionHDN protects mice from acetaminophen-induced liver injury possibly via mechanisms related to inhibition of the expression and releasing of HMGB1.

  • Pharmacological interventions for intrapartum fever in labor analgesia: a meta-analysis

    ObjectiveTo systematically review the clinical efficacy and safety of glucocorticoids, acetaminophen and antimicrobial drugs in the treatment of intrapartum fever in labor analgesia. MethodsThe PubMed, Embase, Cochrane Library, Web of Science, CBM, VIP, and CNKI databases were electronically searched to collect randomized controlled trials (RCTs) of glucocorticoids, acetaminophen, and antimicrobial drugs for intrapartum fever in labor analgesia from inception to June 30, 2023. Two reviewers independently screened the literature, extracted data, and evaluated the risk of bias of the included literature. Meta-analysis was then performed by using RevMan 5.4 software. ResultsA total of 10 RCTs involving 1 337 women were included. Meta-analysis showed that the use of glucocorticoids reduced the incidence of intrapartum fever in women with labor analgesia compared with the control group (OR=0.52, 95%CI 0.33 to 0.82, P<0.01). But there was no statistically significant difference between acetaminophen or antimicrobial drugs and the control group. ConclusionCurrent evidence shows that the use of glucocorticoids can reduce the incidence of intrapartum fever in labor analgesia, but the use of acetaminophen and antimicrobial drugs cannot reduce the incidence of intrapartum fever. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
