Abstract
子宮內膜異位症 (endometriosis) 是婦產科常見的疾病,好發於生育年齡的年輕女性。在臨床及體外試驗指出子宮內膜細胞具有入侵能力以及轉移生長的能力,但目前發病過程及機轉仍不清楚。在臨床上,子宮內膜異位症的主要治療為藥物治療或手術治療。但術後卻有高復發率,而術後若引發輸卵管周圍組織沾黏,更會影響胚胎著床,進而影響生育力。因此如何降低或避免治療後的再復發率及術後沾黏是目前很重要的課題。本論文主要尋找並開發具有抑制子宮內膜異位細胞生長及抗沾黏的生物可吸收性醫材,並且評估其功效性 (efficacy) 及生物安全性 (biosafety)。本研究以聚乳酸-甘醇酸 (poly D,L-lactide-co-glycolide acid, PLGA) 以及聚乙二醇 (poly ethylene glycol, PEG) 所組成的生物可吸收性溫度感應水膠BOX-hydrogel,並加上透明質酸 (hyaluronic acid, HA) 製備複合型水膠進行分析。研究指出子宮內膜異位細胞可以經由上皮細胞間質轉化 (epithelial-mesenchymal transition, EMT) 加速細胞移行、入侵及異位生長。子宮內膜異位組織被證實有大量腫瘤壞死因子 (tumor necrosis factor-α,TNF-α) 表現,引起發炎反應,並與腫瘤細胞的EMT有關。本研究論文,我們探討生物可吸收性溫度感應水膠BOX-hydrogel是否具有抑制由TNF-α所誘導的子宮內膜異位細胞移行、入侵、上皮細胞間質轉化作用及細胞介白素第六因子 (Interleukin-6, IL-6) 和細胞介白素第一因子 (IL-1β)的發炎標誌,並且測試BOX-hydrogel其降解物質對間皮細胞 (Mesothelial cells, Met-5A) 存活率的影響。於體外試驗中,利用西方墨點法分析TNF-α誘導的細胞影響EMT標誌蛋白,發現TNF-α減少cytokeratin和E-cadherin的表達,增加vimentin和N-cadherin的表達,並且增加發炎標誌IL-1β及IL-6表達,增加細胞移行及入侵能力。而複合型水膠添加培養,增加cytokeratin和E-cadherin的表達,減弱上皮細胞間質轉化。並且減少發炎標誌IL-1β及IL-6表達,並引發由TNF-α誘導的子宮內膜異位細胞開始死亡。另外,複合水膠材料的降解試驗觀察到複合水膠降解物質並不會影響到間皮細胞存活。此外於體內試驗中,我們以老鼠腹腔手術模式,觀察BOX-hydrogel、BOX-HALow和BOX-HAHigh複合水膠材料於體內的抗沾黏功效,結果顯示BOX-HALow複合型水膠具有抗沾黏功效最佳。因此顯示複合水膠材料可以抑制子宮內膜異位細胞生長發炎及移行入侵,並且具有手術後抗沾黏功效。
