Antibiotic pretreatment promotes orally-administered triptolide absorption and aggravates hepatotoxicity and intestinal injury in mice.

Ethnopharmacological Relevance: Triptolide (TP) exhibits extensive pharmacological activity, but its hepatotoxicity and intestinal injury are significant and limit its clinical use.

Aim Of The Study: To investigate the effect of gut microbiota disturbance after antibiotic pretreatment on TP-induced hepatotoxicity, intestinal injury and their mechanism.

Materials And Methods: We compared the characteristics of TP-induced hepatotoxicity and intestinal injury in mice with or without antibiotic pretreatment.

Simultaneous determination of eight analytes of Fuzheng Huayu recipe in beagle dog plasma by UHPLC-Q/exactive Orbitrap HRMS and its application to toxicokinetics.

Fuzheng Huayu recipe (FZHY) is a Chinese patent medicine for the treatment of liver fibrosis. This study aimed to investigate the toxicokinetics of FZHY in beagle dogs after oral administration. Blood samples were collected on days 1, 15 and 28 after oral gavage of FZHY dosages of 400 or 1,200 mg/kg body weight once a day.

Effects of a selective cyclooxygenase-2 inhibitor, nimesulide, on the growth of ovarian carcinoma in vivo.

New therapies against cancer are based on targeting cyclooxygenase-2 (COX-2). Whether COX-2 inhibitor therapy would be beneficial in the prevention and/or treatment of ovarian cancer still remains unclear. This study was designed to investigate whether nimesulide, a COX-2 selective inhibitor, could suppress tumor growth in implanted ovarian carcinoma mice and to explore the molecular mechanisms.

[Expressions of Cx43 and Skp2 in epithelial ovarian tumor and their clinical significances].

Background & Objective: Connexin 43 (Cx43), an important member of connexins family, is frequently down-regulated in neoplastic cells. It has been shown to have gap junction-dependent anti-tumor effect on various tumor cell lines. Recently, it was reported that Cx43 could inhibit tumor growth via down-regulating the expression of S-phase kinase associated protein 2 (Skp2).
