Beschreibung
Zusammenfassung:	The invention discloses a method for screening a therapeutic target of acute radiation-induced gastrointestinal syndrome and use of TIGAR target in the preparation of a medicine for treating radiation-induced gastrointestinal syndrome. The CreERT-loxP transgenic mouse model is used, in which quiescent intestinal crypt stem cells are effectively promoted to proliferate after exposure to high-dose ionizing radiation, to screen a therapeutic target that still has a therapeutic effect for radiation-induced gastrointestinal syndrome 18-24 h after ionizing radiation. Gene splicing occurs in particular cells in the CreERT-loxP transgenic mice only after the injection of tamoxifen, thereby regulating gene expression. The actual situation of initial exposure and then treatment after a nuclear accident is well simulated, so the invention is of great practical significance. The screened therapeutic target is developed into a medicine for treatment after nuclear accidents, to save precious time for the treatment after nuclear accidents.
