Abstract: 
Objective: To investigate the effect of tea polyphenols on cardiac function in rats with diabetic cardiomyopathy, and the mechanism by which tea polyphenols regulate autophagy in diabetic cardiomyopathy. Methods: Sixty Sprague-Dawley (SD) rats were randomly divided into six groups: a normal control group (NC), an obesity group (OB), a diabetic cardiomyopathy group (DCM), a tea polyphenol group (TP), an obesity tea polyphenol treatment group (OB-TP), and a diabetic cardiomyopathy tea polyphenol treatment group (DCM-TP). After successful modeling, serum glucose, cholesterol, and triglyceride levels were determined; cardiac structure and function were inspected by ultrasonic cardiography; myocardial pathology was examined by staining with hematoxylin-eosin; transmission electron microscopy was used to observe the morphology and quantity of autophagosomes; and expression levels of autophagy-related proteins LC3-II, SQSTM1/p62, and Beclin-1 were determined by Western blotting. Results: Compared to the NC group, the OB group had normal blood glucose and a high level of blood lipids; both blood glucose and lipids were increased in the DCM group; ultrasonic cardiograms showed that the fraction shortening was reduced in the DCM group. However, these were improved significantly in the DCM-TP group. Hematoxylin-eosin staining showed disordered cardiomyocytes and hypertrophy in the DCM group; however, no differences were found among the remaining groups. Transmission electron microscopy revealed that the numbers of autophagosomes in the DCM and OB-TP groups were obviously increased compared to the NC and OB groups; the number of autophagosomes in the DCM-TP group was reduced. Western blotting showed that the expression of LC3-II/I and Beclin-1 increased obviously, whereas the expression of SQSTM1/p62 was decreased in the DCM and OB-TP groups (P<0.05). Conclusions: tea polyphenols had an effect on diabetic cardiomyopathy in rat cardiac function and may alter the levels of autophagy to improve glucose and lipid metabolism in diabetes.

茶多酚调控自噬改善糖尿病心肌病的机制研究

目的:探究茶多酚对自噬的调控及对糖尿病心肌病大鼠心功能的影响.
创新点:本研究提示了糖尿病可诱导心肌自噬水平增高,而茶多酚可抑制这一现象;相反,高脂血症可抑制心肌自噬,而茶多酚却能诱导被抑制的自噬.
方法:各组大鼠造模成功后测定血中的血糖、血脂水平;心超检测大鼠心脏结构及功能变化;苏木精-伊红(H&E)染色观察心肌结构及病理改变;透射电镜观察自噬体的形态和数量;蛋白质印迹法(Western blotting)检测自噬相关蛋白LC3-II、SQSTM1/p62及Beclin-1的表达水平.
结论:茶多酚对糖尿病心肌病大鼠心功能具有保护作用,机制可能通过调节自噬水平改善糖尿病心肌糖脂代谢紊乱有关.
