A silk fibroin nerve graft fused with NT3 and a preparation method therefor is provided. The method includes the steps of: synthesizing a gene fragment containing a silk fibroin light chain and NT-3, connecting the fragment to a pET-30 expression vector, and transferring the obtained recombinant expression vector into BL21to obtain a fusion protein; placing a silk fibroin fiber web in a mold, mixing the fusion protein and a silk fibroin solution, and performing freeze drying to enable the silk fibroin to be crosslinked with the fusion protein to form a nerve conduit; and after deformation processing, finally obtaining a silk fibroin nerve graft having NT-3 activity. The silk fibroin nerve graft can provide a mechanical support, exert nerve protection and nerve regeneration promotion functions in a long term, and adjust the proportion of NT-3 bioactive peptides in the nerve conduit, facilitating repair of nerve injuries.

Preparation method for silk fibroin nerve graft fused with NT3

A device and method for adjusting a fuel supply advance angle of a multi-cylinder diesel engine includes a gear chamber, a connecting disc and a fuel pump, wherein the gear chamber and the connecting disc are in the diesel engine, and the fuel pump is at a left end surface outside the gear chamber. A main shaft end of the fuel pump extends into the gear chamber. A right end surface of the connecting disc connects to a timing gear. A right end surface of the timing gear has three penetrating circular-arc waist-shaped holes. Annular sizing blocks are arranged on the waist-shaped holes. A penetrating circular hole is at a tail end of the waist-shaped holes. The circular hole is provided with a T-shaped nut. A support screw is arranged in the T-shaped nut, and the screw head of the support screw is jacked against the annular sizing block.

A combined leg structure of a micro bridge unit of a focal plane array adopts a conductive polymer film or a doped conductive polymer film to serve as an extraction electrode in the micro bridge unit of the focal plane array, which contacts a vanadium oxide thermosensitive film or a doped vanadium oxide thermosensitive film of a bridge surface layer, so as to electrically connect the thermosensitive film of the micro bridge unit with a read-out circuit. The combined leg structure includes three layers: respectively an upper SiNx film layer, a lower SiNx film layer and a middle layer of the conductive polymer film or the doped conductive polymer film. The present invention adopts the conductive polymer film or the doped conductive polymer film having a low thermal conductivity to serve as an electrode material. A bridge leg absorption structure is arranged in the combined leg structure.
