Abstract: An isolating switch body, an isolating switch, and a power distribution system are provided. The isolating switch body includes body modules, where each body module includes a plurality of layers of switch units which are stacked, the plurality of layers of switch units are connected through respective body rotating shafts, and a plurality of groups of body modules are spliced to form the isolating switch body; the body rotating shafts of the switch units are linked with an operating mechanism through a transmission mechanism in a first direction perpendicular to a stacking direction. The handle shaft is rotated to drive the operating mechanism to act, and then the body modules are driven through the transmission mechanism to achieve synchronous opening and closing.

Abstract: Use of low dose streptozocin in the preparation of an animal model for screening drugs for treatment of antoimmune type 1 diabetes is disclosed, in which streptozocin is administrated intravenously at a dose of 15-30 mg/kg per time for 5 days and administrated again on the 7th day and 14th day after last time of offering drug. A method for preparing rhesus monkey model of autoimmune type 1 diabetes and autoimmune type 1 diabetes animal model obtained are also disclosed.
