Combined Application of Dexamethasone and Tranexamic Acid to Reduce the Postoperative Inflammatory Response and Improve Functional Outcomes in Total Hip Arthroplasty.

Objective: To evaluate the efficacy and safety of combined use of tranexamic acid (TXA) and dexamethasone (DEX) for anti-inflammatory and clinical outcomes after total hip arthroplasty (THA).

Methods: A total of 100 patients were included in this randomized, controlled study. Patients in the TXA + DEX group were administered TXA at a dose of 15 mg/kg, which was repeated 3 h after THA, and received 20 mg DEX.

[Di-(2-ethylhexyl) phthalate increases the DNA methylation level of genomes in the mouse testis].

Objective: To investigate the effect of the exposure to di- (2-ethylhexyl) phthalate (DEHP) during pregnancy on the DNA methylation level of genomes in the testis of the offspring in mice.

Methods: Pregnant KM mice were randomly divided into three groups, normal control, corn oil and DEHP-exposed. Corn oil and DEHP (500 mg/[kg x d]) were administrated respectively from gestation day 12.
