| 中文摘要: |
| ："治疗性血管新生" 是利用外源性血管生长因子或基因促进缺血部位新生血管形成，达到改善缺血部位血液供应而起到治
疗的目的，该方法为缺血性疾病的治疗提供了新的思路。目前研究的多种与血管生成相关的因子中，血管内皮生长因子（Vascular
Endothelial Growth Factor，VEGF）是公认的最具特异性且作用最强的促进血管生长因子。但由于外源性血管生长因子重组蛋白在
体内半衰期短，试验中难以长时间持续给药起到刺激新血管生成及成熟的作用。研究表明通过超声破坏微泡技术可使基因转染
的靶细胞持续表达该基因。因此，应用超声靶向微泡破坏技术使VEGF 基因在缺血部位持续表达，可起到治疗性血管新生的作
用。本文将就超声微泡介导VEGF基因转染治疗缺血性疾病研究进展进行综述。 |
| 英文摘要: |
| Therapeutic neovascularization is a new concept for the treatment of ischemic vascular diseases. This method can improve
the blood supply of ischemic area and achieve the purpose of treatment by using exogenous vascular growth factor or gene to promote
angiogenesis in ischemic region. Among the several angiogenic growth factors, Vascular Endothelial Growth Factor (VEGF) has
been shown to have a key rolewith stimulating angiogenesis. However the process of growing mature vessels takes time. This time course
poses a significant problem for administration of recombinant VEGF protein, as the half life of VEGF is so short in plasma. Assuming
that VEGF needs to be present throughout the creation of new vessels, but this would be virtually impossible to achieve in a clinical setting
by using the recombinant protein. Gene and stem cell based therapy represents ways by which elevated levels of VEGF can be produced
and sustained for longer period of time. Ultrasound-targeted microbubble destruction (UTMD) is a new strategy for targeting
VEGF gene delivery and can make the gene expressed in a long time. This articlereviewed progress inVEGF gene transfection for treatent
of ischemicdiseases. |
