【Abstract】Objective To introduce the possible effect of endogenous angiogenesis inhibitive factors in the therapy of hepatocarcinoma. Methods Recent relevant literatures were reviewed. ResultsEndogenous angiogenesis inhibitive factors can suppress the growth of tumor blood vessels, which might head off the development and metastasis of hepatocarcinoma effectively. This might provide a new approach to the therapy of hepatocarcinoma. ConclusionRecent studies on endogenous angiogenesis inhibitive factors will be helpful in the prevention and treatment of hepatocarcinoma.
ObjectiveTo summarize the progress on the injury mechanism of vascular endothelial cells in atherosclerosis.MethodsThe latest progress was reviewed in recent literatures.ResultsAll kinds of etiological factors have activated NF-kappa B and cytokines in the development of atherosclerosis, which lead to expression of cell adhesive molecules and adhesion of monocytes to vascular endothelial cells.A variety of inflammatory mediums are released, which can directly damage endothelial cells.Besides, the inflammatory mediums make monocytes and neutrophils attach to endothelial cells by immune mechanisms, which injure the endothelial cells more severely. Meanwhile the damaged membrance structure leads to the production of AECA which activates the complementary system. Then the vascular endothelial cell injury is aggravated and the development of atherosclerosis accelerated. ConclusionIt is very important to recognize the injury mechanism of vascular endothelial cells in the development of atherosclerosis for prevention and treatment of atherosclerosis.
