2-甲氧雌二醇對硬腦膜動靜脈瘺形成中血管新生的抑制作用
[Abstract]:Objective: dural arteriovenous fistula (DAVF) is a major disease of cerebrovascular disease. Its pathological basis is the short circuiting of the vena cava in the dura mater vessels. Our early study suggests the process of "venous sinus hypertension - cerebral hypoperfusion - dural angiogenesis - DAVF formation", and the intervention of angiogenesis is expected to be a new way to prevent and cure DAVF .2- methoxy estradiol (2-ME) has a strong anti angiogenesis effect. Clinical studies have shown that 2-ME has significant angiogenesis inhibition and thus inhibits tumor growth, thus suggesting that it may also interfere with the angiogenesis process of DAVF. This study aims to simulate the pathophysiology of human DAVF through the rat model of venous sinus hypertension. To further verify the intervention effect of 2-ME on the neonatal vascular neovascularization induced by the rat venous sinus pressure model. Methods: the study first detected the expression of angiogenic factors (ID-1, HIF-1 a, VEGF, MMPs, etc.) in the DAVF tissues of the patients, and compared with the histopathological changes in the dura of the intracranial venous hypertension model in rats. Step through Elisa, immunohistochemistry, Western blot, RT-PCR and other methods to study the effect of 2-ME on the transcription and expression of the neovascularization factor in the dura mater, and the effect on the activity of angiogenesis. Results: we found the tissue section of the human DAVF focus and the neovascularization in the dural tissue section of the rat model of intracranial venous hypertension. The expression of 2-ME can inhibit the expression of VEGF, MMP-2/9, HIF-1 alpha and ID-1 gene and protein to a certain extent, and inhibit the new level of the dural blood vessel. This effect can be maintained for 2 weeks after withdrawal. Conclusion: 2-ME is a new type of dural angiogenesis induced by venous sinus hypertension in rats. The inhibitory effect suggests that it has a potential therapeutic value for human DAVF. The first part of the rat model of intracranial venous sinus hypertension and histopathological examination: DAVF is a acquired disease, and many patients have various causes of venous sinus hypertension before the onset of the disease. We think a lot of blood through literature review. Guan Xinsheng factor may be involved in the formation of DAVF, and whether the expression of these angiogenic factors is also in the rat model of intracranial venous hypertension is still unclear. This trial was conducted by comparing the expression of VEGF, MMP-2/9, HIF-1, and ID-1 in the tissue sections of human DAVF lesions and the intracranial venous hypertension model of rats. To verify the pathological changes in the dura tissue of the rat model of intracranial venous hypertension. Methods: 18 specimens of DAVF were selected for immunohistochemical staining and 6 rats were treated with intracranial venous hypertension. After 12 weeks, the epidural sections were stained to compare the expression of angiogenic factor VEGF, MMP-2/9, HIF-1 A and ID-1. Results: human DAVF disease. Conclusion: the intracranial venous pressure model in rats can represent some pathological features of the tissue of human DAVF. The second part of 2- methoxy estradiol can inhibit the neovascularization of the dura mater in the intracranial venous hypertension rats. Objective: the dural arteriovenous fistula (dural arteriovenous fistula) is a complex cerebrovascular disease which can cause intracranial hemorrhage. Recently, we found that chronic intracranial hypoperfusion can cause epidural angiogenesis, or further induce dural arteriovenous fistula. Methoxy estradiol is a metabolic product of estrogen, and has a strong inhibitory effect on angiogenesis. The purpose of this experiment is to verify the inhibitory effect of 2- methoxy estradiol on the epidural angiogenesis in intracranial venous hypertension rats. Methods: 78 male SD rats were used in the experiment. The model of intracranial vein high pressure was used in the animal model, and the model was divided into 2-ME early and late stage. Immunohistochemical, Elisa, Western blot and RT-PCR methods were used to analyze the effect of 2-ME angiogenesis. Results: through histological analysis, serological analysis, Western blot and RT-PCR, 2-ME could inhibit the expression of VEGF, MMP-2/9, HIF-1 A and ID-1 caused by intracranial venous hypertension to a certain extent, and then the effect of the inhibition of epidural angiogenesis. It can be maintained for 2 weeks after the withdrawal. Conclusion: 2-ME has a inhibitory effect on the neovascularization of the dural vessels induced by the high pressure of the venous sinus in rats, suggesting that it has potential therapeutic value for human DAVF.
