摘要:

文题释义:
静电纺丝技术:是指聚合物熔体或者溶液在高压静电场作用下形成纤维的过程。与电喷技术形成的是单分散微米或者纳米聚合物球不同,静电纺丝技术是通过使带电荷的高分子熔体或者溶液在高压静电场中喷射、拉伸、劈裂,固化或者溶剂挥发,最终形成纤维状物质的过程,是目前制备一维纳米结构材料的重要方法之一。
聚偏氟乙烯:是一种多晶型的半结晶氟塑料,具有良好的压电性和生物相容性,用其制备出的电刺激型医用膜可促进各种生长因子的表达和分泌,进而影响细胞的增殖和分化过程,是研究较为广泛的电活性生物材料之一。
背景:课题组前期研究发现,静电纺丝聚偏氟乙烯仿生骨膜具有良好的细胞相容性,但其生物相容性尚不清楚。
目的:评价掺Zn2+、Mg2+聚偏氟乙烯仿生骨膜的生物相容性。
方法:取前期研究采用静电纺丝技术制备的聚偏氟乙烯、掺1%Zn2+聚偏氟乙烯、掺1%Mg2+聚偏氟乙烯、掺1%Zn2++1%Mg2+聚偏氟乙烯仿生骨膜,制备各组仿生骨膜浸提液,选择SD大鼠为实验对象,进行溶血实验、短期全身毒性实验、热源实验,选择豚鼠为实验对象,进行皮肤致敏实验,检测4组仿生骨膜的生物相容性。
结果与结论:①溶血实验结果显示,掺1%Zn2+聚偏氟乙烯、掺1%Mg2+聚偏氟乙烯、掺1%Zn2++1%Mg2+聚偏氟乙烯仿生骨膜及聚偏氟乙烯浸提液的溶血率分别为(0.130±0.013)%,(0.149±0.020)%,(0.466±0.018)%,(0.037±0.018)%,符合生物材料血液相容性性标准;②短期全身毒性实验结果显示,4组仿生骨膜浸提液灌胃干预后未引起SD大鼠体质量减轻、摄食量变化及呼吸困难等毒性体征,对大鼠的主要脏器无毒性作用;③热源实验结果显示,掺1%Zn2+聚偏氟乙烯、掺1%Mg2+聚偏氟乙烯、掺1%Zn2++1%Mg2+聚偏氟乙烯及聚偏氟乙烯仿生骨膜浸提液干预后,SD大鼠体温升高值分别为(0.133±0.058),(0.100±0.010),(0.300±0.010),(0.300±0.017) ℃,均小于0.6 ℃,体温升高度数总和均小于1.4 ℃;④皮肤致敏实验结果显示,4组仿生骨膜浸提液干预后豚鼠皮下未见红斑与水肿。结果表明:聚偏氟乙烯与掺Zn2+、Mg2+聚偏氟乙烯仿生骨膜具有良好的生物相容性。

Abstract: BACKGROUND: Our previous studies have found that poly(vinylidene fluoride) bionic periosteum prepared by electrospinning has good cytocompatibility, but its biocompatibility is unknown.
OBJECTIVE: To evaluate the biocompatibility of poly(vinylidene fluoride) bionic periosteum doped with Zn2+ and Mg2+. 
METHODS: Poly(vinylidene fluoride), poly(vinylidene fluoride) bionic periosteum doped with 1% Zn2+, doped with 1% Mg2+, and doped with 1% (Zn2++Mg2+) were prepared by electrospinning to make bionic periosteum extract. SD rats were selected as the experimental subjects for hemolysis test, short-term systemic toxicity test, and heat source test. Guinea pigs were selected as the experimental subjects for skin sensitization test. The biocompatibility of bionic periosteum of four groups was tested. 
RESULTS AND CONCLUSION: (1) The hemolysis test results showed that the hemolysis rates of 1% Zn2+ poly(vinylidene fluoride), 1% Mg2+ poly (vinylidene fluoride), 1% Zn2++1% Mg2+ poly(vinylidene fluoride) bionic periosteum and poly(vinylidene fluoride) extract were (0.130±0.013)%, (0.149±0.020)%, (0.466±0.018)%, and (0.037±0.018)%, respectively, which met the hemocompatibility standard of biomaterials. (2) The results of short-term systemic toxicity test showed that the four groups of bionic periosteal extract had no toxic signs such as body mass reduction, food intake changes, and dyspnea in SD rats, and had no toxic effects on major organs of rats. (3) Heat source test results showed that after intervention with poly(vinylidene fluoride) bionic periosteum doped with 1% Zn2+, doped with 1% Mg2+, and doped with 1% (Zn2++Mg2+),  and poly(vinylidene fluoride) bionic periosteum extract, the elevated body temperature values of SD rats were (0.133±0.058), (0.100±0.010), (0.300±0.010), and (0.300±0.017) °C, respectively. All were less than 0.6 °C, and the total temperature increase was less than 1.4 °C. (4) The results of skin sensitization test showed that no erythema or edema was observed under the skin of guinea pigs after the intervention of bionic periosteum extract of four groups. (5) The results showed that poly(vinylidene fluoride) and poly(vinylidene fluoride) bionic periosteum doped with Zn2+ and Mg2+ had good biocompatibility.
