Methods: A total of 110 elderly patients with coronary heart disease and chronic heart failure according to random data table were divided into control group (n=54) and observation group (n=56). The patients in control group were treated with conventional drug, and patients in the observation group received conventional drug combined with aerobic exercise training. Before and after treatment, levels of red blood cell parameters, vascular endothelial function and cardiac function indexes were compared between the two groups. Results: Before treatment, the difference of HCT, RDW, RBC, NO, ET-1, LVEF, LVEDD and LVESD levels in the two groups were not significantly. After treatment, HCT and RBC levels in two groups were no statistically significant difference;The levels of RDW, ET-1, LVEDD and LVESD in observation group were significantly lower than those in this group before treatment, and significantly lower than those in the control group after treatment;The levels of NO and LVEF in two groups were significantly higher than those in the group before treatment, and levels of NO and LVEF in the observation group were significantly higher than those in control group after treatment. Conclusion: The clinical effect of aerobic exercise training combined with conventional drug in treatment of senile coronary heart disease with chronic heart failure was significant, which can effectively increase the RDW level of patients, improve vascular endothelial function and heart function, it has important clinical value.展开更多

The levels of serum slCAM-1, sVCAM-1 and CBV-IgM were measured by using enzyme-linked immunosorbent assay in 22 patients with chronic Keshan disease （CKD）, 27 with latent Keshan disease （LKD） and 28 healthy controis. The subjects in different groups were adjusted for sex and age. Echocardiography was adopted to determine left ventricular ejection fraction （LVEF） in 22 patients with CKD. The results showed that CKD patients had significantly higher levels of slCAM-1 and sVCAM-1 than LKD patients and healthy controls （P〈0.01 for all）. And there was significant difference in the levels of the 2 adhesion molecules between LKD patients and healthy controls （P〈0.05）. A negative correlation was found between LVEF and slCAM-1 or sVCAM-1 in CKD patients. The percentage of CBV-specific IgM positive individuals in KD patients was significantly higher than that of healthy controls. In CVB-specific IgM positive patients, the levels of serum slCAM-1 and sVCAM-1 were significantly greater than those in CBV-specific IgM negative counterpart. It was concluded that the increase in the levels of slCAM-1 and sVCAM-1 suggests the progression of inflammation in KD. slCAM-1 and sVCAM-1 can promote the development of myocardial pathology and lead to poor myocardial function. The increased serum slCAM-1 and sVCAM-1 in KD patients may be related to CBV infection.展开更多

DM affects approximately 350 million individuals worldwide and additional millions that remain undiagnosed are estimated to suffer from the complications of DM. Although the complications of DM can be seen throughout the body, the nervous, cardiac, and vascular systems can be significantly affected and lead to disorders that include cognitive loss, stroke, atherosclerosis, cardiac failure, and endothelial stem cell impairment. At the cellular level, oxidativestress is a significant determinant of cell fate during DM and leads to endoplasmic reticulum stress, mitochondrial dysfunction, apoptosis, and autophagy. Multiple strategies are being developed to combat the complications of DM, but it is the mechanistic target of rapamycin(mTOR) that is gaining interest in drug development circles especially for protective therapies that involve cytokines and growth factors such as erythropoietin. The pathways of mTOR linked to mTOR complex 1, mTOR complex 2, AMP activated protein kinase, and the hamartin(tuberous sclerosis 1)/tuberin(tuberous sclerosis 2) complex can ultimately influence neuronal, cardiac, and vascular cell survival during oxidant stress in DM through a fine interplay between apoptosis and autophagy. Further understanding of these mTOR regulated pathways should foster novel strategies for the complications of DM that impact millions of individuals with death and disability.展开更多
