Abstract: The present disclosure provides methods and compositions for the treatment of cancer using an ACAT1 inhibitor in combination with an immune checkpoint inhibitor. The immune checkpoint inhibitor may inhibit the programmed cell death protein 1 (PD-1), programmed death-ligand 1 (PD-L1), cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), lymphocyte-activation protein 3 (LAG-3), or combinations thereof. The ACAT1 inhibitor may be avasimibe, pactimibe, or purpactins, without limitation.

Abstract: An insulation sleeve insertion device for inserting insulating sleeves into wiring slots of a flat wire motor stator, comprising a processing panel, a feeder, a conveying mechanism comprising conveyor belts, a positioning mechanism comprising a limit ring and a positioning turntable, a guide mechanism comprising a plurality of second guide rails, a clamping mechanism comprising a drive rod, a positioning plate set, and a drive mechanism comprising a second driver, wherein the clamping mechanism is configured to insert insulating sleeves into wiring slots of the flat wire motor stator through the guide mechanism.

Abstract: A method for inserting insulating sleeves into wiring slots of a flat wire motor stator, including: S1: selecting a plurality of insulating sleeves matched with a size of wiring slots of a flat wire motor stator, and pre-processing the insulating sleeves to a length by cutting according to a size of the flat wire motor stator; S2: conveying the pre-processed insulating sleeves, through a conveying mechanism, to a positioning mechanism located behind the conveying mechanism; S3: clamping the insulating sleeves in the positioning mechanism above the wiring slots of the flat wire motor stator by a clamping mechanism; S4: moving a guide mechanism above the flat wire motor stator in the positioning plate set, where S4 is synchronized with S3; S5: repeating S1 to S7 until the space factor of the wiring slots of the flat wire motor stator reaches the set value.
