Abstract: The present invention provides a method for predicting whether an individual has early myocardial infarction. The method includes: providing a blood sample of the individual; testing a marker in the blood sample to obtain the quantity of the marker; comparing the obtained number with a preset threshold, and judging whether the individual will suffer from myocardial infarction by the comparison, wherein the marker is any one or more nucleotide sequences of miRNA, lncRNA or circRNA.

Abstract: Provided is an isolated CTLA4 monoclonal antibody. The antibody can highly-specifically bind to CTLA4, and can effectively block the binding of CTLA4 to B7, reduce the activity or expression level of CTLA4, relieve the inhibition of CTLA4 on the immune function of an organism, activate T lymphocytes, and effectively treat tumors and immune system diseases. Also provided are a monoclonal antibody conjugate comprising the pharmaceutical composition and diagnostic composition of the antibody, and the use thereof in the preparation of a drug for preventing and/or treating and/or treating in combination tumors and immune system diseases.

Abstract: Provided herein is a human monoclonal antibody 8D6 against hepatitis C virus (HCV) infection. The antibody binds to the E2 subunit of HCV capsid protein, and can prevent HCV from infecting susceptible host cells. By using the antibody variable region gene or the complementary determining region (CDR) gene, different forms of genetic engineering antibodies have been transformed and produced in any expression system of the prokaryotic and eukaryotic cells as therapeutics to prevent or treat HCV infection.

Abstract: A set of cellular genes that were identified by siRNA screening as being essential for Human Immunodeficiency Virus (HIV) infection. These genes are host cellular factors involved in DNA repair, specifically in the base excision repair pathway.
