Abstract: Disclosed are target for screening anti-tumor drug, application use thereof and screening method therefor. Disclosed are a target for screening a drug for treating and/or preventing tumors, the target for screening the drug for treating and/or preventing tumors comprise selenoprotein; and a target for screening a drug for preventing tumor metastasis, the target for screening the drug for preventing the tumor metastasis comprising selenoprotein. Also disclosed is a method for screening a drug for treating and/or preventing tumors or a drug for preventing tumor metastasis, the method comprising: interacting a candidate drug with the selenoprotein; and screening the drug for treating and/or preventing tumors or the drug for preventing tumor metastasis according to an affinity between the candidate drug and the selenoprotein; and the candidate drug with a high affinity with the selenoprotein is taken as a candidate primarily screened drug.

Abstract: A carrier mechanism for walking on a line includes a carrier platform constituted by a first mounting plate, a second mounting plate and a longitudinal movable plate, a walking apparatus, a clamping apparatus, a driving apparatus, and a self-balance control apparatus configured to adjust a posture of the carrier mechanism. The longitudinal movable plate is slidably arranged on the second mounting plate fixedly connected to the first mounting plate in parallel. The walking apparatus includes at least two sets of walking wheels arranged along a walking direction. The clamping apparatus is slidably arranged on the lower side of the longitudinal movable plate. The driving apparatus includes a first driving apparatus configured to drive the walking wheels to roll, and a second driving apparatus configured to drive the longitudinal movable plate to move. The clamping apparatus is driven by the longitudinal movable plate to clamp or release a to-be-inspected target.
