Description
技术领域
本发明涉及吻合器及其制备方法,特别是涉及一种肿瘤切割吻合器钛钉及其制备方法。
背景技术
肿瘤的吻合器切割是肿瘤手术切除手段的一种升级,较传统的手术切除,操作更简便易行、出血少、手术时间短,具有一定优势。但是肿瘤具有侵袭、转移特性,以及考虑到肿瘤切除后病人机体的正常生理功能,往往会导致有部分肿瘤细胞残余,然而这些残余肿瘤有可能会重新发展成为新的实体瘤,从而形成更加恶性的肿瘤。
通常情况下,术后会对病人进行化疗,以巩固治疗结果,但是无论是口服药还是注射制剂,都要经历复杂的血液循环***以及体内的生物学屏障,大大降低药物利用效率并会导致用,从而限制了化疗疗效。而吻合器切割后,钛钉会存留在体内的原肿瘤病灶部位,如果将化疗药物结合到钛钉表面,持续释放抗肿瘤药物,可以起到提高药物利用效率、减缓毒副作用的目的,进一步清除参与肿瘤细胞,防止复发。
发明内容
发明目的:本发明的目的是提供一种肿瘤切割吻合器钛钉及其制备方法,该吻合器钛钉可以在肿瘤切除后,在体内持续释放甲氨蝶呤,进一步清除肿瘤细胞,有效预防肿瘤复发。
技术方案:本发明所述的一种肿瘤切割吻合器钛钉,其包括钛钉,钛钉表面修饰有肿瘤药物释放层。
其中,所述释放层通过含二硫键的中间体将抗肿瘤药甲氨蝶呤修饰到钛钉的表面。
上述肿瘤切割吻合器钛钉制备方法包括以下步骤:
(1)对吻合钉进行表面羟基化处理;
(2)将羟基化的吻合钉放入3-羧丙基三乙氧烷丙酮溶液中浸泡,搅拌、浸泡处理后用丙酮冲洗并烘干;
(3)将上述吻合钉浸泡在含有L-胱氨酸二甲酯二盐酸盐、1-(3-二甲氨基丙基)-3-乙基碳二亚胺盐酸盐(EDC)、N-羟基琥珀酰亚胺(NHS)的水溶液中,搅拌、浸泡后取出用去离子水冲洗并烘干;
(4)将上述吻合钉浸泡在含有甲氨蝶呤、1-(3-二甲氨基丙基)-3-乙基碳二亚胺盐酸盐、N-羟基琥珀酰亚胺的丙酮溶液中,搅拌、浸泡处理后清洗烘干,即可。
优选地,步骤(1)中,将吻合钉置于等离子表面处理仪,控制温度10~30℃,功率2~10Kw,时间10~30min,对吻合钉进行表面羟基化处理。
步骤(2)中,溶液中3-羧丙基三乙氧烷丙酮的浓度为0.1~5mol/L,浸泡1~2h,反应温度为40~80℃。
步骤(3)中,L-胱氨酸二甲酯二盐酸盐的浓度为0.5~2mol/L,L-胱氨酸二甲酯二盐酸盐、EDC、NHS的摩尔比为1∶(1~1.5)∶(1~1.5),反应时间为8~24h,反应温度为10~40℃
步骤(4)中,甲氨蝶呤的浓度为0.1~2mol/L,甲氨蝶呤、EDC、NHS的摩尔比为1∶(1~1.2)∶(1~1.2),反应时间为12~24h,反应温度为25~60℃。
其中,该吻合钉的表面结构如下:
具体制备过程的原理如下:
(a)吻合钉的表面羟基化
利用等离子体表面处理仪对吻合钉进行表面羟基化处理;
(b)钛钉的表面处理
将羟基化的吻合钉依次在下述三种溶液中浸泡:①3-羧丙基三乙氧烷丙酮溶液;②L-胱氨酸二甲酯二盐酸盐(简写为:CysM)、1-(3-二甲氨基丙基)-3-乙基碳二亚胺盐酸盐(EDC)、N-羟基琥珀酰亚胺(NHS)的水溶液;③甲氨蝶呤、EDC、NHS的水溶液。每一步都进行洗涤烘干处理。
本发明中的钛钉通过二硫键修饰抗肿瘤药物甲氨蝶呤,能够在肿瘤切割手术后持续释放甲氨蝶呤,进一步清除残余肿瘤细胞。该钛钉能够在肿瘤切除后,会因肿瘤部位高表达的谷胱甘肽的作用而释放甲氨蝶呤。
本发明的主要目的是对目前已有的肿瘤切割吻合器钛钉的功能化修饰,解决吻合器切割只具有手术切割的单一功能的问题。而单一吻合器切割通常易出现癌细胞残留问题,进而导致肿瘤复发。本发明的的钛钉能够在存在癌细胞残留时及时释放甲氨蝶呤,进一步清除残余肿瘤细胞,有效预防肿瘤复发。
有益效果:本发明所制备的吻合钉能够在使用吻合器切除肿瘤后,残余肿瘤细胞的增殖会高表达谷胱甘肽,从而致使CysM中的二硫键断裂,从而致使甲氨蝶呤释放,进一步清除残存的肿瘤细胞,预防肿瘤复发。
附图说明
图1是按实施例制备的吻合钉在不同浓度的谷胱甘肽溶液中释放甲氨蝶呤的累积量随时间变化曲线。
