The invention belongs to the technical field of biomedical research, and particularly relates to an effect of HIF-1a in liver abscess caused by high-toxicity klebsiella pneumoniae infection in a high glucose state. The invention aims to solve the main problem of providing a treatment target for liver abscess caused by high-toxicity klebsiella pneumoniae infection related to diabetes mellitus. As a transcription factor for regulating in-vivo balance, HIF-1a participates in maintaining the integrity of an epithelial barrier, and it is proved that HIF-1a is not reported in type 2 diabetes mellitus in alcoholic hepatitis, inflammatory bowel disease and other models through the anti-inflammatory and antimicrobial functions of immune cells. Modeling finds that the expression of HIF-1a in a type 2 diabetes mellitus combined high-virulence klebsiella pneumoniae infection model is reduced, and inflammation can be obviously relieved after intervention by adding an HIF-1a activating agent. HIF-1a is prompted to be capable of serving as a treatment target of the diabetes-related high-toxicity klebsiella pneumoniae liver abscess.
