This invention discloses a preparation process for a targeted drug delivery system based on the synergistic effect of Lamp2b and IMTP, comprising the following steps: constructing cells overexpressing the Lamp2b-IMTP fusion protein, culturing cells overexpressing the Lamp2b-IMTP fusion protein, thereby obtaining the targeted drug delivery system. The Lamp2b / IMTP synergistic targeted drug delivery system obtained by this invention allows for the specific accumulation of drugs in target cells, such as tumor cells, achieving precise drug delivery. The fundamental localization role of Lamp2b: Lamp2b is a naturally occurring transmembrane protein on the surface of exosomes, responsible for mediating the "initial recognition" between exosomes and recipient cells, ensuring that the delivery system, with exosomes as the core carrier, can be effectively recognized and bound by cells, avoiding rapid clearance by the body as a "foreign substance."

The synchronous belt comprises a main body unit, a tooth portion layer unit and a back portion layer unit, the main body unit comprises a first main body portion and a second main body portion, and the first main body portion and the second main body portion are arranged in a stacked mode. A tensile cord unit is arranged between the first main body part and the second main body part, the first main body part, the second main body part and the tensile cord unit extend in the same direction, and the tensile cord unit comprises a plurality of oil-resistant glass wire pieces. The first main body part and the second main body part are both made of a rubber material formed by mixing a hydrogenated nitrile butadiene layer and a fiber layer, the fiber length in the fiber layer ranges from 2 mm to 6.5 mm, and the second main body part is arranged close to the second side and protrudes outwards to form a tooth part. The cable at least has the following advantages: the cable has better oil resistance and tensile strength, higher temperature resistance coefficient and better friction coefficient.

The application discloses a track automatic switching device for an aerial suspension trolley conveying line, which comprises a base body, a front straight track arranged at the front end of the base body, a rear straight track arranged at the rear end of the base body, a left turning rear track and a right turning rear track, the base body is fixed at the track connection position of the front straight track and the rear straight track, a movable track is arranged on the base body, a straight track for butt joint with the front straight track and the rear straight track, a left turning track for butt joint with the front straight track and the left turning rear track and a right turning track for butt joint with the front straight track and the right turning rear track are arranged on the movable track, a track power device is arranged on the movable track and is used for driving the movable track to move, and a positioning assembly is arranged on the movable track and is used for improving the accuracy of track butt joint and the stability of the track. The application improves the guiding accuracy of the aerial suspension trolley in the track switching process, and solves the problems of large space occupation and high failure rate in the track switching process when the driving stroke is large.
