Effects of Astragalus polysaccharide on the structure and function of skeletal muscle in D-galactose-induced C57BL/6J mice.

Objective: To investigate the effects of Astragalus polysaccharide (APS) on skeletal muscle structure and function in D-galactose (D-gal)-induced C57BL/6J mice.

Methods: Eighteen male C57BL/6J mice of specific pathogen-free (SPF) grade, aged 8 weeks, were selected and divided into three groups: a control group (0.9% saline gavage for 16 weeks), a D-gal group (subcutaneous injection of 200 mg/kg D-galactose in the upper neck region, once daily for 8 weeks), and a D-gal + APS group (subcutaneous injection of 200 mg/kg D-galactose, once daily for 8 weeks, with concurrent administration of 100 mg/kg APS by gavage for 8 weeks).

The efficacy and safety of remimazolam tosylate versus propofol in patients undergoing colonoscopy: a multicentered, randomized, positive-controlled, phase III clinical trial.

This study aimed to evaluate the efficacy and safety of remimazolam tosylate versus propofol in patients undergoing colonoscopy. In this multicentered, blinded, randomized, active-controlled, non-inferior phase III trial, 384 eligible patients who were about to undergo colonoscopy were randomized as a ratio of 1:1 into remimazolam and propofol group. Procedure success was assessed and defined as the completion of colonoscopy without administration of rescue sedative agent or more than 5 top-ups of trial drug in any 15 minute-period after initial administration of trial drug.
