摘要:

文题释义:
电纺丝:是一种利用聚合物溶液或熔体在强电场下的喷射来制备纳米级超精细纤维的新型加工方法,在外加电场作用下,被表面张力作用保持在喷嘴处的高分子液滴在电场诱导下表面聚集电荷,受到与表面方向相反的电场力作用;当电场力足够大时,聚合物液滴战胜外表张力构成喷发细流,细流在喷发进程中溶剂蒸腾或固化,最终形成纳米级的纤维,并随机沉降落在接纳设备上形成连续的交联纤维支架结构。
桂皮醛:别名肉桂醛,是桂皮的主要成分,属于苯丙醛类,被广泛应用于食品添加剂中,熔点为-7.5 ℃,沸点为253 ℃,为无色或淡黄色液体,难溶于水、甘油和石油醇,易溶于丙酮、乙醇、二氯甲烷、氯仿、四氯化碳等有机溶剂;临床上常用于解热、抗炎、镇痛、抗菌、抗肿瘤、抗氧化,近年来有研究发现桂皮醛在降血糖和促进成骨方面效果显著。

背景:前期研究发现,桂皮醛对高糖环境下成骨细胞的生物学性能具有促进作用。
目的:以静电纺丝薄膜为载体观察桂皮醛对高糖环境下成骨细胞增殖与分化的影响。
方法:采用静电纺丝法制备聚己内酯薄膜。将对数生长期的MC3T3-E1细胞分4组培养:空白对照组加入高糖培养液,聚己内酯组加入聚己内酯薄膜支架与高糖培养液,药物组加入含桂皮醛的高糖培养液,联合组加入聚己内酯薄膜与含桂皮醛的高糖培养液。培养1,4,7 d时,采用CCK-8法检测细胞增殖,碱性磷酸酶试剂盒检测细胞碱性磷酸酶活性;培养7 d时,采用RT-qPCR法检测细胞骨钙蛋白mRNA表达。
结果与结论:①CCK-8检测显示,聚己内酯组、药物组、联合组各时间点的细胞增殖快于空白对照组(P < 0.05),联合组培养4,7 d时的细胞增殖快于聚己内酯组、药物组(P < 0.05),药物组培养4,7 d时的细胞增殖快于聚己内酯组(P < 0.05);②聚己内酯组、药物组、联合组培养4,7 d时的碱性磷酸酶活性高于空白对照组(P < 0.05),联合组培养4,7 d时的碱性磷酸酶活性高于聚己内酯组、药物组(P < 0.05),药物组培养7 d时的碱性磷酸酶活性高于聚己内酯组(P < 0.05);③4组骨钙蛋白mRNA表达由高到低依次为联合组、药物组、聚己内酯组、空白对照组,组间两两比较差异均有显著性意义(P < 0.05);④结果表明,聚己内酯静电纺丝薄膜与桂皮醛可协同促进高糖环境下成骨细胞的增殖与分化。

Abstract: BACKGROUND:  Previous studies have found that cinnamaldehyde can promote the biological properties of osteoblasts in high glucose environment.
OBJECTIVE: To observe the effect of cinnamaldehyde on proliferation and differentiation of osteoblasts under high glucose with electrospinning membrane as carrier. 
METHODS: The polycaprolactone membranes were prepared by electrospinning. MC3T3-E1 cells in logarithmic growth phase were divided into four groups: blank control group was added with high glucose medium. Polycaprolactone group was added with polycaprolactone membrane scaffold and high glucose medium. Drug group was added with high glucose medium containing cinnamaldehyde. Combined group was added with polycaprolactone membrane and high glucose medium containing cinnamaldehyde. CCK-8 method was used to detect cell proliferation and alkaline phosphatase kit was used to detect alkaline phosphatase activity at 1, 4 and 7 days of culture. RT-qPCR was used to detect the expression of osteocalcin mRNA at 7 days.
RESULTS AND CONCLUSION: (1) CCK-8 assay showed that the cell proliferation of polycaprolactone group, drug group and combined group was faster than that of blank control group at each time point (P < 0.05). Cell proliferation of combined group was faster than that of polycaprolactone group and drug group at 4 and 7 days (P < 0.05), and cell proliferation of drug group was faster than that of polycaprolactone group at 4 and 7 days (P < 0.05). (2) The alkaline phosphatase activity of polycaprolactone group, drug group, and combined group was higher than that of blank control group at 4 and 7 days (P < 0.05). The alkaline phosphatase activity of combined group was higher than that of polycaprolactone group and drug group at 4 and 7 days (P < 0.05). The alkaline phosphatase activity of drug group was higher than that of polycaprolactone group at 7 days (P < 0.05). (3) The expression of osteocalcin mRNA in the four groups from high to low was the combined group, drug group, polycaprolactone group, and blank control group; there were significant differences between the two groups (P < 0.05). (4) Results suggest that polycaprolactone electrospinning membrane and cinnamaldehyde can promote the proliferation and differentiation of osteoblasts in high glucose environment.
