目的  研究擔(dān)載抗腫瘤藥物5-氟尿嘧啶(5-FU)的左旋聚乳酸(PLLA)共混羊毛蛋白納米纖維藥膜的緩釋功能及其對結(jié)腸癌細胞的體外抑制效果。
方法  將PLLA與羊毛蛋白共混交聯(lián),并加入抗腫瘤藥物5-FU,利用高壓靜電紡絲技術(shù)將共混溶液制作成具有緩釋效果的納米纖維薄膜。通過掃描電鏡(SEM)觀察其形貌。以高效液相色譜法(HPLC)測定5-FU/PLLA羊毛蛋白藥膜中5-FU的緩釋效果。采用噻唑藍(MTT)比色法,檢測藥膜對結(jié)腸癌細胞HCT116的體外殺傷效果。同時采用倒置相差顯微鏡、透射電子顯微鏡(TEM)觀測實驗組細胞的生長情況。
結(jié)果  由SEM可以看出5-FU能夠均勻分布在納米纖維藥膜中,HPLC顯示5-FU能夠緩慢釋放并基本符合零級動力學(xué)規(guī)律。采用不同處理因素后,通過顯微鏡觀察,藥膜浸泡時間越長的實驗組細胞出現(xiàn)腫脹、凋亡、壞死的情況越明顯。MTT檢測納米藥膜實驗組的細胞存活率為(47.5±2.8)%,而不含藥物的純膜組對細胞基本無影響,其存活率為(93.9±2.8)%,差異具有統(tǒng)計學(xué)意義(P<0.01)。
結(jié)論  5-FU/PLLA羊毛蛋白納米藥膜有明顯緩釋效果,具有較好的腫瘤細胞抑制作用和潛在的醫(yī)療應(yīng)用價值。
