Abstract: A recombinant human fibroblast growth factor 21 (rhFGF21) fusion protein, a polynucleotide encoding the rhFGF21 fusion protein, a recombinant expression vector, a recombinant cell, a pharmaceutical composition and a kit containing the rhFGF21 fusion protein, a use of the rhFGF21 fusion protein, and a method for producing the rhFGF21 fusion protein. Efficient and soluble expression is achieved using a genetic engineering method to obtain a rhFGF21-(VPGXG)n fusion protein, wherein by means of fusion of rhFGF21 and an elastin-like protein (VPGXG)n having an appropriate cycle number n, the resulting fusion protein has better biological activity than wild-type rhFGF21. Moreover, experimental results indicate that the rhFGF21-(VPGXG)n fusion protein has high expression efficiency, and can effectively reduce the blood sugar level in the body of a diabetic animal. In addition, compared with wild-type hFGF21, the fusion protein also has the advantage of a long efficacy duration in reducing the blood sugar level.

Abstract: A system and method for knowledge based information modeling using a semantic binding engine that generates a binding configuration based on a legacy domain semantic model extracted from a controller of an autonomous system and a knowledge graph extracted from a knowledge repository of domain knowledge related to the autonomous system. The binding configuration represents a mapping of standardized model instance components to a component of the legacy domain semantic model. An adapter with a server processes communications related to a standardized information model, including information requests that are translated to a set of process variables of the legacy domain semantic model using the binding configuration.
