The application discloses a bamboo Dichelus quadernarius nymph trap, an attracting and avoiding agent and an application method, and belongs to the technical field of forest protection science, which comprises a plug rod, a socket is fixed to the top of the plug rod, a slow-release bottle is installed on the top of the socket, diffusion sponges are evenly arranged on the outer side of the plug rod in a circumferential direction, a drainage groove is arranged in the inner top of the plug rod and is used for conducting the bottom end of the slow-release bottle and the diffusion sponges, and a mounting disc is horizontally rotationally installed below the socket at the top of the plug rod. The plug rod is fixed and inserted into a bamboo forest, the slow-release bottle is arranged on the socket at the top of the plug rod, the inside of the slow-release bottle is filled with an attracting agent, target nymphs are attracted, and the cross-shaped glue boards distributed on the side of the plug rod can capture the attracted nymphs, so that the pollution of chemical control to the environment and the excessive consumption of manpower of physical control are avoided, in addition, the slow-release bottles containing the avoiding agent are placed between adjacent devices, the attracting agent and the avoiding agent are used in cooperation, and the trapping efficiency is improved.

Medical devices and related methods useful in EVAC procedures are described. A medical device can include a sponge. The sponge can include a plurality of perforations forming one or more tear surfaces. The one or more tear surfaces can define a predetermined location for removal of a first portion of the sponge from a second portion of the sponge. The one or more tear surfaces can form a boundary between a radially inner surface of the first portion and a radially outer surface of the second portion. The medical device can also include a tube coupled to a proximal portion of the sponge.

The application discloses a marine-derived compound Cpd-8 and application thereof in preparation of a medicine for resisting TNF-induced cell death. Through screening of an extract library of marine-derived sponge symbiotic fungi of a research group, a small-molecule inhibitor with a novel structure is obtained, which can resist TNF-induced cell death, and specifically, the marine-derived sesquiterpene lactone nitrobenzene analogue Cpd-8 and a pharmaceutically acceptable salt thereof. The compound can inhibit TNF-induced cell death and formation of a complex II in a signal pathway, thereby exerting an anti-cell death activity. In-vitro cell experiment results show that the compound of the application can significantly inhibit TNF-induced cell death. In-vivo animal experiment results show that the compound of the application can inhibit TNF-alpha / D-GaIN (D-galactosamine)-induced acute liver injury, and significantly prolong the survival period of mice.

This utility model relates to the field of edible fungi production equipment, specifically a sponge queuing mechanism for a sponge-filling machine. It includes a frame, a material hopper, a sponging assembly, a lifting assembly, a sponge-packing assembly, and a sponge-topping assembly. The frame provides stable support for the equipment. The material hopper stores sponges. In the sponging assembly, a geared motor drives a chain to move multiple stirring shafts, employing an alternating "lower engagement - upper engagement" transmission mode. This causes the stirring shafts to rotate in opposite directions, creating a vortex that, in conjunction with the stirring rods, fully loosens the sponges and prevents clumping. The lifting assembly, through the linkage of a drive motor, a reducer, a transmission shaft and transmission gears, and a chain, drives the lifting base to rise and fall stably along the lifting guide rail, achieving precise sponge collection from the sponge-packing cylinder. After resetting, the ejector rod on the ejector frame in the sponge-topping assembly pushes the sponge-topping rod, ejecting any remaining sponges from the sponge-packing cylinder out of the material hopper and preventing blockage.

The utility model provides a kind of giant grass substrate gastrodia elata cultivation device, including bottom shell, the upper side of the bottom shell is fixedly connected with cultivation shell, the inside of the upper side of the bottom shell is located cultivation shell and is provided with giant grass substrate, the inside of the bottom shell is provided with water supplement mechanism, one side of the inside of the bottom shell is equipped with water-absorbing sponge, the upper side of the bottom shell is provided with a plurality of ceramic capillary tubes. By setting ceramic capillary tube, water-absorbing sponge, water supplement mechanism and reflux structure, ceramic capillary tube is assisted by water-absorbing sponge, can continuously and evenly deliver moisture to giant grass substrate, avoid substrate local water shortage, water supplement mechanism changes water level by floating ball sensing, automatically opens or closes water supplement, ensure that there is always sufficient moisture in bottom shell to deliver, reflux structure can recycle the excess moisture in cultivation shell to bottom shell, prevent substrate ponding, to provide stable suitable humidity environment for gastrodia elata, guarantee its normal growth.

This utility model discloses an agricultural seedling cultivation bed, relating to the field of seedling beds. It includes a container with an open top, into which a seedling box is connected. The seedling box has a hollow interior and an open top. Protruding plates are integrally formed at both ends of the top of the seedling box, with the bottom ends of the protruding plates contacting the top of the container. Multiple seedling sponges are detachably connected to the interior of the protruding plates via a docking mechanism. A downwardly recessed seed hole is integrally formed at the center of the top of each seedling sponge, and an upwardly recessed root hole is formed at the center of the bottom of each seedling sponge. The seed hole communicates with the interior of the root hole. This utility model, by incorporating a docking mechanism, facilitates the neat assembly of the seedling sponges and allows for one-time removal, improving the efficiency of removal and transfer.
