Description

Application of YL-IPA08 in preparation of medicine for repairing functions after ischemic stroke
Technical Field
The invention belongs to the technical field of biological medicines, and particularly relates to application of YL-IPA08 in preparation of a medicine for repairing functions after ischemic stroke.
Background
Stroke (stroke) is an acute cerebrovascular disease in which the blood rheology is altered by the blockage or rupture of blood vessels, which in turn causes brain injury. The Chinese stroke incidence is one of the countries with the highest worldwide incidence, the cerebral stroke disability rate is about 75 percent, and the Chinese stroke disability rate is the first cause of disability of adults in China. Stroke places a heavy burden on people and society in our country.
Clinically, the more effective treatment of acute ischemic stroke is recanalization. But because of the narrow time window of treatment, few patients can benefit from this. The second is a cerebroprotective agent treatment, but neuroprotective agents present some clinical transformation disorders. There is no treatment scheme and drug effective in promoting post-stroke brain recovery or improving long-term prognosis, and even if thrombolytic in time, the neurological damage after ischemia cannot be significantly improved. Therefore, the search for effective therapeutic drugs for ischemic stroke and the promotion of the functional recovery of cranial nerves after stroke are scientific problems to be solved urgently at present.
The 18KD Translocator Protein (TSPO) is located predominantly on the outer mitochondrial membrane of glial cells in the brain. Under physiological conditions, the expression level of TSPO in the central nervous system is very low, but under certain pathological conditions, TSPO expression increases in activated microglia and astrocytes, and is more significantly expressed in activated microglia in particular. Early laboratory studies found that a large number of microglia were activated after stroke, whereas TSPO was highly expressed on all activated microglia subpopulations.

The following two cases are considered as walking errors: 1) The left forelimb of the mouse penetrates into the grid hole and cannot support the body; 2) When the mouse is at rest, the left forelimb wrist is level with the grid. Mouse left forelimb error percentage (%) = left forelimb error number/(left forelimb error number + left forelimb correct step number) × 100%.
