Abstract: The present disclosure relates to an operating table, the operating table comprising a table top, a table top support and a column with a column head, wherein the sealing device is bellows assembled below the column head, or an adhesive in a hole and/or window on the holder of the cable, or a sealing gasket between the receiver and the column head, or a shield sealingly attached to the column head below the gear. The present disclosure further relates to control equipment, a lifting device, an intelligent charger, a column guide system for an operating table, as well as an operating table including the same.

Abstract: The present invention provides an energy-storing temperature control material, and belongs to the technical field of temperature control materials. In the energy-storing temperature control material provided in the present invention, the organic synthetic fiber based phase-change material has a three-dimensional dispersion effect, and can form a network constraint for remaining phase-change materials to reinforce mechanical properties of the materials, thereby fixing shapes of the materials and avoiding a liquid-crystal phase separation phenomenon in the phase-change process. The phase-change energy storage agent can absorb and release the heat by means of solid-liquid phase conversion of the material, to achieve the temperature control effect; and the phase-change temperature regulator can regulate a phase-change temperature range of the phase-change material, to make the energy-storing temperature control material suitable for climatic features of northern China.

Abstract: A serum-free culture medium for in vitro maturation of bovine oocytes includes a Hepes-free M199 basal medium, fatty acid-free BSA, human menopausal gonadotrophin (HMG), 17?-estradiol, epidermal growth factor (EGF), L-cysteine, bFGF, Glutamax (100×), folic acid, cholic acid and CXCL12.
