Heart failure is a continuously developing syndrome of cardiac insufficiency caused by diseases, which becomes a major disease endangering human health as well as one of the main causes of death in patients with cardiovascular diseases. The occurrence of heart failure is related to hemodynamic abnormalities, neuroendocrine hormones, myocardial damage, myocardial remodeling etc, lead to the clinical manifestations including dyspnea, fatigue and fluid retention with complex pathophysiological mechanisms. Currently available drugs such as cardiac glycoside, diuretic, angiotensin-converting enzyme inhibitor, vasodilator and β receptor blocker etc are widely used for the treatment of heart failure. In particular, natural products and related active ingredients have the characteristics of mild efficacy, low toxicity, multi-target comprehensive efficacy, and have obvious advantages in restoring cardiac function, reducing energy disorder and improving quality of life. In this review, we mainly focus on the recent advance including mechanisms and active ingredients of natural products for the treatment of heart failure, which will provide the inspiration for the development of more potent clinical drugs against heart failure.

Objective: To study the expression and significance of KAI1/CD82, p27 proteins in gastric carcinoma. Methods: The expressions of KAI1/CD82, p27 proteins were detected by immunohistchemistry S-P method in 58 cases of gastric carcinoma tissues and 23 normal gastric tissues. Results: The positive rates of KAI1/CD82 and p27 proteins in gastric carcinoma tissues were 29.3% and 34.4%, but 90% and 85% respectively in normal gastric tissue. And there is a significant difference between the two groups. The expression level of KAI1/CD82 and p27 proteins was significantly related to tumor invasive depth, grade of tumor differentiation, the clinical stage and lymph node metastasis, And has nothing to do with age or gender. There was a positive correlation between the expression of KAI1/CD82 and P27 in gastric cancer tissues. Conclusion: The expression of KAI1/CD82 and p27 protein may be involved in the initiation and development in gastric carcinoma, and the combined detection of KAI1/CD82 and p27 proteins may be significant in predicting the invision and metastasis of gastric carcinoma.
