摘要:

文题释义:
人工血管:是严重狭窄或闭塞性血管的人工替代品,多是以尼龙、涤纶、聚四氟乙烯等合成材料人工制造的,适用于全身各处的血管转流术,大、中口径人工血管应用于临床已取得满意的效果。
一氧化氮:为氮氧化合物,化学式NO,相对分子质量为30.01,为二价化合物,是一种无色无味气体难溶于水的有毒气体,化学性质非常活泼。


背景:人工血管材料在生理水平上的一氧化氮(NO)稳定可控释放是抑制小直径人工血管内壁血栓形成的技术关键,对新型人工血管材料的研发具有重要意义。
目的:梳理近年来人工血管材料的研究和应用进展,重点对NO释放型人工血管材料进行综述。
方法:以“vascular graft、blood vessel、catalytic Nitric oxide、tissue engineering;人工血管,催化NO”等为检索关键词,检索CNKI、万方、谷歌学术和PubMed数据库2000年1月至2020年7月发表的相关文献,再对检索到的文献进行筛选、归纳和总结。
结果与结论:一系列聚合物材料、涂层材料和纳米复合材料展现出与天然内皮组织相似的NO产生通量和释放速率,其中负载有机硒、铜离子、角蛋白、纳米贵金属等的人工血管材料显示出可用于心血管疾病治疗的巨大潜力。负载有机硒的人工血管材料催化持续时间长,生物相容性好,机械性能优良;负载铜的人工血管材料生物安全性好,抗血栓能力强;同时负载有机硒和铜离子的人工血管材料表现出长期稳定的催化能力,以及选择性的内皮细胞活性增强能力;含有角蛋白的人工血管材料具有出色的细胞相容性和功能可拓展性;其他含有催化NO生成物质的人工血管材料未来发展空间较大。但截至目前,释放NO的可植入生物材料的临床前开发或后期临床试验效果尚不明确,在NO的释放时间、对内皮细胞的影响等方面仍存在一些重要问题有待解决。

Abstract:

BACKGROUND: The stable and controllable release of nitric oxide from artificial blood vessel materials at the physiological level is not only the key technology to inhibit the formation of thrombus on small-diameter artificial blood vessel inner walls, but also is of great significance for developing novel artificial blood vessel materials. 

OBJECTIVE: To review the research and application progress of artificial blood vessel materials in recent years, and focus on introducing nitric oxide-releasing artificial blood vessel materials.

METHODS: CNKI, Wanfang, Google Scholar, and PubMed databases were searched with key words such as “vascular graft, blood vessel, catalytic nitric oxide, tissue engineering” in English, “artificial blood vessel, catalytic NO” in Chinese from January 2000 to July 2020 for relevant articles. The retrieved articles were screened and summarized.
RESULTS AND CONCLUSION: A series of polymer materials, coating materials and nano composite materials exhibited similar nitric oxide production flux and release rate with natural endothelial tissues. Among them, artificial blood vessel materials loaded with organic selenium, copper ions, keratin, and nano-noble metals have shown great potentialities in the treatment of cardiovascular diseases. The artificial blood vessel materials loaded with organic selenium had long catalytic durations, good biocompatibilities, and excellent mechanical properties. The artificial blood vessel materials loaded with copper had good biological safeties and strong anti-thrombotic abilities. The performance of artificial blood vessel materials loaded with organic selenium and copper ions showed long-term and stable catalytic abilities and selective enhancement abilities of endothelial cell activities. Artificial blood vessel materials containing keratin showed excellent cell compatibility and functional expansibilities. The other artificial blood vessel materials containing substances that could catalyze nitric oxide production also exhibited good potential developments in the future. Up to now, the effects of pre-clinical development or post-clinical trials of implantable biomaterials that release nitric oxide are still unclear, and some important technical issues such as the release time of nitric oxide and the effects on endothelial cells need to be resolved.
