The invention relates to an ivermectin detection kit, in particular to an ivermectin chemiluminescence enzyme-linked immunoassay rapid detection kit. The ivermectin chemiluminescence enzyme-linked immunoassay rapid detection kit comprises a kit body, an elisa plate arranged in the kit body and a reagent filled in the kit body, wherein each hole of the elisa plate is coated with coating antigens, the coating antigens are prepared by coupling metabolites of ivermectin with ovalbumin; the reagent comprises monoclonal antibodies of the ivermectin, elisa secondary antibodies, namely horseradish peroxidase-marked goat-anti-mouse antibodies, ivermectin series of standard solutions, concentrated phosphate buffer liquid, concentrated washing liquid and luminescent liquid. By using the kit, due to the adoption of the steps of adding a sample, washing, adding the elisa secondary antibodies, washing, adding the luminescent liquid, detecting, and judging results, the prepared kit has high sensitivity which can reach 0.01 to 5 ng/ml and has a wide linear dynamic range; an analysis method is simple, convenient and quick, the results are stable, and the error is small; the analysis results are sensitive, stable and reliable; the safety is high; the using period is long.

The invention discloses a production method of a microbial bacteriostatic deodorizer and application of the microbial bacteriostatic deodorizer, and relates to the technical field of production of cleaning supplies for daily use. The production method comprises the following steps: (1) producing microbial fermentation liquor; (2) conducting microbial fermentation; (3) adding a plant additive intoa fermentation product, conducting even mixing, and allowing standing; (4) conducting granulation; (5) conducting programmed drying; (6) covering dried granules with porous surface layers; and (7) conducting rapid cooling after thermal treatment is conducted to obtain the microbial bacteriostatic deodorizer. According to the provided microbial bacteriostatic deodorizer, traditional bacteriostaticdeodorizer modes are broken through, forming can be well achieved with the microbial activity guaranteed, the novel microbial deodorizer in a solid form can be suitable for multiple kinds of complex environments, and is not liable to go bad, and the service life is long.

The invention relates to the field of diagnosis and treatment of cancers and discloses an application of LINC00266-1 polypeptide as a solid tumor marker. Measurement of the LINC00266-1 polypeptide canbe used for detecting or diagnosing tumors or evaluating and monitoring prognosis of a patient.

The invention finds down-regulation expression of miR-154-5p in prostate cancer bone metastasis tissue for the first time, and the down-regulation expression of the miR-154-5p can predict that the lifetime without bone metastasis is relatively short. In-vivo and in-vitro research further determines that up-regulation of the miR-154-5p inhibits bone metastasis of PCa in vivo, and up-regulation of the miR-154-5p inhibits migration, invasion and proliferation of PCa cells. Based on the result, the invention provides a new application of the miR-154-5p in bone metastasis of prostate cancer.

The invention discloses a magnet recovery device of a rubbish cleaning car. The device is characterized by comprising broom brushes, a magnetic spindle, a supporting frame and an iron scrap receiving box, wherein the broom brushes are installed on two sides of a chassis by vertically fixed spindles respectively; the broom brushes have double-layer round disk structures; brush fur clusters are installed on the bottom faces of the broom brushes; brush fur at the round disk center is 0.5-0.8 cm shorter than the brush fur on outer layers; the magnetic spindle is installed in the middle parts of the broom brushes by a horizontal fixation spindle; an exhaust opening is formed in the side parallel to the magnetic spindle; the iron scrap receiving box is installed on the other side of the magnetic spindle; the magnetic spindle is firmly connected to the iron scrap receiving box by the supporting frame; and an interface of the iron scrap receiving box is tangent to the outer wall of the magnetic spindle. The device has the advantages that the structure is simple; operations are convenient; the round disk broom brushes are driven by a motor to sweep the ground; iron scraps on the bottom face are cleaned up by the magnetic spindle and are rotated and collected into the iron scrap receiving box in time; collection efficiency is high; and the device is energy-saving and environment-friendly.

The invention discloses a Media Access Control (MAC) mechanism for a digital-energy integrated wireless sensor network, which is applied to the field of wireless sensor networks and aims at solving the problems in the prior art. According to the invention, a wireless data and energy simultaneous transmission technology is introduced; the superframe structure of the traditional IEEE 802.15. 4 protocol is changed; the GTS time slot allocation scheme of the wireless access point is optimized; the residual energy of the terminal node, the numerical value difference between the two acquired data and the life validity period of the newly acquired data are used as judgment conditions to guide the distribution of the GTS time slot; a support vector machine algorithm of machine learning is introduced, supervised learning is carried out according to historical data to obtain a learner model of a support vector machine, a decision boundary value of the learner model serves as a GTS time slot application reference value, and a GTS time slot application scheme is determined by comparing the decision boundary value with the reference value.
