Objective To provide a reference basis for the establishment of ideal animal models of leukemia,the characteristics of animal models of leukemia was summarized.Methods The themes of"leukemia"and"animal"were searched in CNKI databases.The relevant literature on animal experiments of leukemia from January 2010 to August 2024 were screened.And a database by Excel 2017 tables was established by organizing their research animal strains,modeling methods and testing indexes to analyze the characteristics of leukemia animal models.Results After comparative analysis,it was found that the animal strains in modeling were BALB/C-nude mice(40 times,29.86%)and NOD/SCID mice(32 times,23.88%),respectively.The modeling method was transplanted cells(127 times,93.38%),and the detection indexes were pathological tissues(80 times,14.84%),blood smears(75 times.13.91%),general condition(73 times,13.54%),bone marrow smear(73 times,13.54%),flow cytometry(55 times,10.20%),blood routine(50 times,9.28%).Conclusion The existing animal models of leukemia are complex and diverse.

Stroke， including ischemic stroke and hemorrhagic stroke， has the characteristics of high morbidity， high disability rate， high mortality rate， high recurrence rate， and high economic burden. Ischemic stroke is the most common type of stroke， which is mainly caused by intracranial artery occlusion. The clinical manifestations of patients are hemiplegia， aphasia， sensory disturbance， and other neurological deficits， accompanied by gastrointestinal symptoms such as constipation and gastrointestinal bleeding. Intestinal flora plays an important role in the pathogenesis of ischemic stroke， and its potential biological effects have received extensive attention. Intestinal flora can not only affect intestinal barrier function but also regulate gastrointestinal immunity and affect host homeostasis. In recent years， traditional Chinese medicine （TCM） has shown remarkable effects and small adverse reactions in the prevention and treatment of cerebral ischemia. The research on the effect of TCM in improving cerebral ischemia injury by regulating the structure and metabolism of intestinal flora and maintaining the function of intestinal flora has gradually become a hot topic. Based on the interaction between TCM and intestinal flora in relevant literature in recent years， this review investigated the mechanism of anti-cerebral ischemic injury of TCM via regulating intestinal flora structure， affecting intestinal flora metabolism， and regulating body immunity and made a summary， proving a basis for further elucidating the role of intestinal flora in cerebral ischemia and the mechanism of TCM in prevention and treatment of ischemic stroke.
