Abstract: The present invention provides a use of IGF-1 in the preparation of medicaments for preventing and/or treating liver tumors, relating to the technological field of prevention and treatment of hepatocarcinoma. In embodiments of the present invention, experiments are carried out on mice, demonstrating that over-expression of IGF-1 in hepatocytes induces the apoptosis of cancerous cells indirectly, and inhibits the occurrence and development of liver tumors; high level of IGF-1 significantly promotes the function of thymus, delays the degeneration of thymus, and does not cause the dysfunction of thymus; high level of IGF-1 significantly promotes the function of spleen T lymphocyte; high level of IGF-1 significantly enhances the number and activity of tumor infiltrating T lymphocytes; long-term over-expression of IGF-1 does not significantly promote the incidence of tumors in all organs and tissues in mice, indicating the safety of high IGF-1 level in the body.

Abstract: The present invention discloses an enzyme-linked immunosorbent assay kit for detecting dinitolmide and use thereof. The enzyme-linked immunosorbent assay kit of the present invention comprises dinitolmide antibody and coating antigen and enzyme conjugate; wherein, the dinitolmide antibody is dinitolmide monoclonal antibody or dinitolmide polyclonal antibody; when the coating antigen is the conjugate of dinitolmide hapten and carrier protein, the enzyme conjugate is enzyme-labeled secondary antibody, or enzyme-labeled specific anti-dinitolmide monoclonal or polyclonal antibody; when the coating antigen is dinitolmide antibody or secondary antibody, the enzyme conjugate is enzyme-labeled dinitolmide hapten. The enzyme-linked immunosorbent assay kit has a simple structure, and it is convenient for use, cheap and portable. Its detection is high effective, accurate, and convenient. It can be used for on-site monitoring and is suitable for qualitative and quantitative screenings of a great number of samples.
