The application provides application of phenolic compounds and / or pharmaceutically acceptable salts thereof in preparation of drugs for treating breast cancer, a pharmaceutical composition, and relates to the technical field of biological medicines.The application of phenolic compounds and / or pharmaceutically acceptable salts thereof in preparation of drugs for treating breast cancer, wherein the phenolic compounds include compound 1 and / or compound 2.The compound 1 (arnebidin) and the compound 2 ((+)-(R)-de-O-methyllasiodiplodin) used in the application have good inhibiting effects on human triple-negative breast cancer MDA-MB-231 cell strains, the IC 50 value of the compound 1 is 1.16 muM, the IC 50 value of the compound 2 is 0.68 muM, which provides a new choice for developing a therapeutic drug for triple-negative breast cancer, and has a good application prospect in preparation of drugs for treating breast cancer, in particular, drugs for treating triple-negative breast cancer.

The utility model provides a cable transporting device. The cable transporting device comprises a box body and a transporting frame. The transporting frame is arranged in the box body and connected to the bottom of the box body, and the peripheral face of the transporting frame is separated from the inner wall face of the box body. The top of the box body is provided with a first opening communicating with the outside and the interior of the box body, the first opening is arranged upwards, and the peripheral face of the transportation frame is used for winding a cable entering the box body from the first opening. According to the cable transportation device, the whole formed by the box body and the transportation frame is used for winding the cable, the operation step that the transportation frame is lifted relative to the box body can be avoided, and therefore the cable bearing capacity of a single transportation frame can be increased, and the safety problem possibly generated in the lifting process is avoided.

The application discloses a conveying line carrier with stress structure on the lower side, which comprises a coupling frame, and further comprises: a front walking part arranged on the front side of the coupling frame and provided with a front stress rod, the stress end of the front stress rod extending to the lower side to receive the pushing force of a pushing piece on the conveying line; a rear walking part arranged on the rear side of the coupling frame and provided with a movable rear stress rod, a first elastic force acting on the rear stress rod to make the stress end of the rear stress rod deviate from the running track of the pushing piece; and a middle stress rod movably arranged on the lower side of the coupling frame and located in the interval between the front walking part and the rear walking part, a second elastic force acting on the middle stress rod to make the stress end of the middle stress rod deviate from the running track of the pushing piece. The stress end of the middle stress rod and the stress end of the rear stress rod are both provided with pressure receiving structures for receiving the pressure of a pressure piece arranged on the conveying line to make the stress end of the middle stress rod and the stress end of the rear stress rod extend into the running track of the pushing piece.

This invention provides an extruder terminal block and an extruder. The extruder terminal block includes a copper post and a first set screw. The copper post has a fixed end and a connecting end. The fixed end has a threaded hole, the internal thread of which is adapted to the external thread on the connecting post of the extruder heating block, so that the fixed end is used to connect the connecting post. The connecting end has a through hole for inserting a cable. The first set screw passes through the wall of the connecting end and can move radially along the copper post, thereby squeezing and releasing the cable in the through hole. The extruder terminal block of this invention connects and conducts electricity between the connecting post of the heating block and the cable through the copper post and the first set screw, exhibiting high connection stability and a large current carrying capacity.

This utility model relates to the field of mechanical manufacturing technology and discloses a pipe fitting support frame. The support frame includes at least two support frame bodies spaced apart along a first direction. Each support frame body includes a bottom beam, the length of which extends along a second direction. A longitudinal beam is vertically connected to the bottom beam, the length of which extends along a third direction. The first, second, and third directions are perpendicular to each other. Multiple support crossbeams are spaced apart along the length of the longitudinal beam. All the bottom beams form a bottom support group. Each support crossbeam on each support frame body, together with a corresponding support crossbeam on another support frame body, forms a pipe fitting support group. Both the bottom support group and the pipe fitting support group are used to place pipe fittings. It has a small footprint, a large load-bearing capacity, and facilitates the stacking and handling of pipe fittings.
