The application provides application of tetrahydropalmatine in preparation of a medicine for treating acute and chronic contact dermatitis. Experiments show that tetrahydropalmatine can significantly inhibit redness, desquamation and ear swelling of acute and chronic contact dermatitis, reduce itching, inhibit epidermal thickening and inflammatory infiltration. The mechanism of action includes double inhibition of TSLP and TNF-alpha protein levels, and recovery of EDEM3 expression by directly combining EDEM3 protein (KD=3.69±0.21 muM), inhibition of endoplasmic reticulum stress, and thus down-regulation of epithelial alarm substances IL25, IL33 and TSLP. The effect of tetrahydropalmatine disappears after EDEM3 is silenced, confirming that EDEM3 is a functional target protein. In addition, tetrahydropalmatine is also effective for non-histamine-dependent allergic contact dermatitis, and has no side effects such as skin atrophy and weight loss, and the safety is better than that of dexamethasone. The application also relates to similar application of tetrahydropalmatine and cortex phellodendri extract. The application provides a safe, effective and mechanism-confirmed new type of therapeutic drug for contact dermatitis.

The utility model relates to the technical field of coating barrel transfer, and discloses a coating barrel transfer device which comprises a platform plate, a U-shaped plate is fixedly connected to the top of the platform plate, a material storage mechanism is arranged on the U-shaped plate and comprises a main body plate, the main body plate is arranged on the top of the platform plate, a threaded rod is rotationally connected to the inner side of the U-shaped plate, and the threaded rod is arranged on the top of the platform plate. One end of the threaded rod is rotationally connected with the top of the platform plate. Through the design of the material storage mechanism, the coating barrels are placed and stored in different placing frames, then the platform plate is controlled to move to transfer the coating barrels, during loading and unloading in the transfer process, a motor works to drive a threaded rod to rotate, the threaded rod is promoted to drive a main body plate to ascend and descend, and therefore when the coating barrels are loaded and unloaded, the placing frames are controlled to descend to the low position, and the coating barrels are transferred. And compared with the operation that the coating barrel needs to be manually loaded and unloaded to the high position, more physical strength is saved, and safety is achieved.

This invention provides a fluororubber using naphthylhydrazone imide as a crosslinking agent, its preparation method, and its applications, belonging to the field of chemical materials. It is prepared from raw materials comprising the following parts by weight: 100 parts of fluororubber raw rubber, 10-30 parts of reinforcing filler, 0-3 parts of internal release agent, 5-20 parts of acid scavenger, 0.5-2 parts of naphthylhydrazone imide, and 0.5-1.5 parts of accelerator; wherein the naphthylhydrazone imide is a monohydroxy-substituted naphthylhydrazone. This invention uses naphthylhydrazone imide to replace bisphenol AF as the crosslinking agent in the fluororubber system.
