  • Publication number: 20200323786
    Abstract: Growth factors are of great potential in regenerative medicine. However, their clinical applications are largely limited in by short in vivo half-lives and a narrow therapeutic window. Thus, a robust controlled release system remains an unmet medical need for growth-factor-based therapies. A nanoscale controlled release system (degradable protein nanocapsule) is provided via in-situ polymerization on growth factor. The release rate can be finely tuned by engineering the surface polymer composition. Improved therapeutic outcomes are achieved with the growth factor nanocapsules, as illustrated in spinal cord fusion mediated by bone morphogenetic protein-2 (BMP-2) nanocapsules.

The method includes steps of: constructing an n*n fundamental matrix according to a preset constraint condition; performing a cyclic shift by taking each row vector of the fundamental matrix as a unit to generate (n?1) expansive matrixes; and generating a target H matrix according to the fundamental matrix and the expansive matrixes. Due to the implementation of the present application, an optimal H matrix is constructed by taking the thought of lowering the space complexity of an H matrix and reducing the hardware cost into consideration on the premise that a single-error-correcting and double-error-detecting function of a Hamming code is not affected; and a cyclic shift method is provided in combination with properties of the optimal H matrix, and a required target optimal H matrix may be formed by regularly expanding the constructed fundamental matrix.
