To summarise the clinical experience of Professor TONG Xiaolin in treating prediabetes combined with overweight or obesity using the method of relieving depression and reducing turbidity. It is believed that prediabetes belongs to the category of "spleen-heat syndrome" in traditional Chinese medicine， and its core pathogenesis is center fullness with internal heat， while obesity is the initiating factor for exacerbating center fullness and internal heat， therefore， it is of great significance to reduce the risk of diabetes by interrupting the transformation between overweight， obesity and glucose metabolism abnormality. It is proposed that the main pathogenesis of prediabetes combined with overweight or obesity is qi depression and turbidity obstruction in middle jiao， with qi depression as the root and turbidity obstruction as the cause， forming a treatment idea with the method of relieving depression and reducing turbidity as the core. In clinic， Dahuang Huanglian Xiexin Decoction （大黄黄连泻心汤） is used as the basic prescription， with a primary focus on directing the turbid downward， supplemented by regulating qi， which embodies the concept of "promoting movement through descent， then figuring out the root of spleen-heat syndrome. Furthermore， the treatment is flexibly modified based on the patient's deficiency-excess syndrome to ensure individualized therapy.

The Mongolian gerbil currently used as laboratory animals worldwide all originates from China.As early as the 1930s,wild Mongolian gerbils were domesticated and introduced into medical research.Today,they have become recognized multifunctional laboratory animals and are extensively used in various fields such as brain nerve studies,parasitology and microbiology,and oncology,etc.Mongolian gerbils possess unique anatomical characteristics in the basal cerebral arteries,such as a congenital absence of the Willis'circle,making it possible to construct cerebral ischemia or cerebral ischemia-reperfusion injury models with simple procedures of unilateral common carotid artery ligation,while also enabling intra-individual control.These anatomical features also increase their sensitivity to cerebral ischemia and make them more prone to cochlear ischemia,therefore playing a crucial role in the preparation of auditory impairment models.The disease progression and pathological manifestations in Mongolian gerbils show many similarities to those observed in human patients.Researchers have successfully used Mongolian gerbils to develop models of cerebral ischemia,cerebral ischemia-reperfusion,cochlear ischemia,cochlear implantation,and sensorineural hearing loss,achieving significant results.This article focuses on the current methods and assessment indicators for constructing Mongolian gerbils models of cerebral ischemia and auditory impairment.It discusses the advantages and disadvantages of various modelling techniques,and explores their application progress,aiming to provide a theoretical basis and reference for the application of Mongolian gerbils in these two important research areas.
