AIM:To investigate the expression and significance of thrombospondin-1(TSP-1)in left ventricular myocardium of type 2 diabetic cardiomyopathy(DCM).METHODS:The rat model of DCM was established by eating a high-fat diet together with injection of low dose streptozocin(30 mg/kg)intrapertoneally.After 12 weeks,the content of collagen was quantified by Masson staining.The mRNA level of TSP-1 was determined by quantification real-time RT-PCR,while the protein level of TSP-1 was analyzed by Western blotting and immunohistochemistry.RESULTS:Compared with the control group,the content of collagen in the DCM group was increased greatly(11.01?3.05 vs 16.92?3.18,P

The field of traditional Chinese medicine has a long history of applying modern science method in related research,and has made significant achievements in the field of disease and syndrome animal models.This paper reviewed the development history of the animal model of spleen deficiency syndrome,summarized and commented the modeling method,animal selection,evaluation index,digestive system disease and syndrome combination model.Small rodents,such as rats,are commonly used as representative animal models in research.Currently,the academic community mostly focuses on etiology and pathogenesis modeling,with limited use of chemical drugs and physical factors for modeling.The most common approach is the complex factor modeling method.Evaluation indicators include traditional Chinese medicine syndrome indicators,quantitative indicators related to"spleen"function and characteristics,as well as prescription counter-indicators.The focus of current research is the combination of disease patterns related to spleen deficiency,such as functional diarrhea/dyspepsia.The research on animal models of spleen.
