Objective To establish an animal model of metabolic syndrome which is prone to atherosclerosis. Methods Eight rabbits were randomly selected from in total of 16 rabbits as control group who were fed with normal rabbit feed. And the rest were used as model group, who were fed with high fat diet. Animals were weigh every week, and triacylg-lycerol (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), and glucose (GLU) content were tested in the 8th, 10th , 13th, 16th and 18th week. Femoral arterial blood pressure and insu-lin (INS) content were assessed at the end of experimental period which is the 18th week;Also, aortic sclerosis rating, arterial stiffness index, abdominal fat coefficient, liver coefficient and cardiac coefficient were calculated and heart, aorta, liver and lower extremity artery pathology were examed. Results Compared with the control group, weight in the model group in-creased significantly;Serum levels of TC, HDL-C, blood pressure abdominal fat coefficient, liver coefficient were significant-ly increased in model group;the whole blood viscosity, plasma viscosity and blood pressure fat coefficient, liver coefficient, aortic sclerosis rating, arterial stiffness index, and GLU all increased significantly in model group;while HDL-C/TCHO, in-sulin sensitivity index decreased significantly in model group(P < 0.05 or P<0.01). Conclusion Food induced method can form metabolic syndrome and atherosclerosis in rabbit model.

Objective To study the effects of enriched rehabilitative training on the expression of microtu-bule associated protein 2 (MAP-2) and synaptophysin (SYN), and to explore its relationship with brain plasticity. Methods Seventy-seven male Wistar rats weighing 160 to 200 g were randomly divided into an ischemia + enriched rehabilitation group (IE, n=36), an ischemia + standard rehabilitation group(IS, n=8), a sham ischemia + en-riched rehabilitation group (SE, n=21) and a sham ischemia + standard rehabilitation group (SS, n=12). Rats in the ischemia groups had their middle cerebral artery sutured for two hours before reperfusion, while those in the sham groups had a similar operation without occlusion. The enriched groups were given enriched rehabilitative train-ing, while the standard groups were left without any training. Behavioral tests, including the acrobatic performance, were administered once daily 2 days after operation, and SP staining of MAP2 and SYN were used to observe the func-tional recovery and brain plasticity changes among the groups at 1,7, 14, 21 and 28 days after the operations. Re-sults Acrobatic performance times reduced gradually. Bederson scores were significantly better in the IE than in the IS group by the 28th day after the operation). There was no significant difference between IE and IS groups in a foot fault test). The expression of MAP-2 and SYN around the infarct and in the hippocampus decreased significantly at first), then recovered gradually. The expression of MAP-2 and SYN in the IE group was significantly higher than that in the IS group at various time points of observation). Conclusion Enriched rehabilitative training can improve functional recovery and the expression of MAP-2 and SYN after brain ischemia, and the functional enhancement may attribute to the brain plasticity.

Atherosclerosis is a vascular disease characterized by arterial occlusion formed by the pathological accumulation of pathological vascular cells and apoptotic cell debris. Atherosclerotic vulnerable plaque is an important pathological basis for inducing severe thrombotic cardiovascular events, and the study of its etiology and pathogenesis has always been a hot issue in the field of cardiovascular research. Efferocytosis is a new type of programmed death cell removal, which refers to the process of macrophages phagocytosing and degrading apoptotic cells to prevent secondary necrosis. It is a key homeostatic mechanism in the body's physiological process. In the pathological state, the dysfunction of efferocytosis causes the pathological accumulation of apoptotic cells and necrotic debris, leading to the occurrence of secondary cell necrosis and the continuous release of intracellular toxic content and inducing inflammatory regression disorders and cholesterol metabolism disorders, which are closely related to the occurrence and development of atherosclerotic vulnerable plaques. The theory of ''blood stasis and toxin'' is an important theory of traditional Chinese medicine (TCM) to explain the occurrence and development of atherosclerosis. Atherosclerosis starts from the pathological state of blood stagnation. Prolonged blood stagnation leads to blood stasis and toxic substances. Blood stasis and toxic pathogens interact with each other in blood vessels and eventually form plaques in blood vessels. The theory of ''blood stasis and toxin causing a catastrophe'' is an important understanding of the occurrence and development of acute cardiovascular events. From the perspective of TCM theory, the pathophysiological mechanism of efferocytosis is similar to the etiology and pathogenesis of the ''blood stasis and toxin'' in TCM. Therefore, this paper took the theory of ''blood stasis and toxin'' as the breakthrough point to explore the mechanism of efferocytosis in atherosclerotic vulnerable plaques, and proposed a detoxification and blood circulation method to regulate cell burial to prevent and treat atherosclerotic vulnerable plaques. The research strategy aims to provide new ideas and theoretical basis for the prevention and treatment of atherosclerosis by detoxification and blood circulation.

Refractory angina is characterized by recurrent and persistent angina with a duration of not less than three months, which is related to reversible ischemia and hypoxia caused by coronary stenosis and obstruction. It mainly involves obstructive coronary artery disease and non-obstructive coronary artery disease with coronary artery spasm and coronary microvascular dysfunction. “Stasis and toxin” play an important role in the pathogenesis of cardiovascular diseases. The pathogenesis of stasis and toxin is stubborn filthy turbidity featured by slow accumulation and sudden onset,and rapid changes,which coincides with the characteristics of refractory angina which is complex and changeable,prolonged and difficult to cure. The pathogenesis of refractory angina involves a combination of underlying deficiency and excessive manifestation, with "stasis and toxin" playing a crucial role as an important pathological factor in the whole process of refractory angina. Traditional Chinese medicine (TCM) employs a holistic approach known as "activating blood circulation and removing toxins", which is supplemented by various methods to tonify Qi and warm Yang, nourish the kidneys and invigorate the spleen, clear heat and transform phlegm. This approach applies anti-inflammatory measures, regulates lipid metabolism, inhibits oxidative stress and thrombus formation, protects endothelial function in blood vessels, as well as establishes collateral circulation for the prevention and treatment of refractory angina. Therefore,based on the theory of "stasis and toxin",combined with TCM theory and modern medical research,this paper discusses the pathogenesis of refractory angina and the prevention and treatment strategy of TCM,and elucidates the reasons for the difficulty in curing refractory angina and the relationship between refractory angina and common angina pectoris,coronary microvascular dysfunction,coronary artery spasm and obstructive coronary artery disease,hoping to provide certain theoretical basis and clinical ideas for the prevention and treatment of refractory angina with TCM.
