Abstract
阿休曼症候群 (Asherman’s Syndrome) 是一項後天性子宮疾病,常於子宮內發生結痂 (synechiae)、沾黏 (adhesion),子宮壁黏合,造成子宮腔或子宮頸產生部分或完全閉塞。施行人工流產或子宮刮勺術後常發生沾黏及感染,造成子宮內膜受傷。若引發輸卵管周圍組織沾黏,子宮腔纖維化 (fibrosis),進而影響胚胎著床。患者因為引發子宮內腔阻塞或空間過少,進而導致不孕和復發性流產。因此如何降低或避免治療後的沾黏、結痂組織形成及子宮纖維化是目前重要的課題。本論文主要是尋找並開發能抗沾黏的生物可吸收性醫材。本研究將以生物可吸收性溫度感應BOX Hydrogel水膠及透明質酸 (Hyaluronic acid)製備複合水膠材料BioGel。我們以此具有可塑性、生物相容性、可降解性的BioGel作為物理阻隔材料,評估其降低或避免手術後沾黏、組織發炎、子宮纖維化及增加子宮內膜修復。我們進行小鼠子宮刮勺術後分為五組,分別為不做任何手術 (Sham),刮勺手術後不置入任何材料 (Surgery) 或在受傷的子宮上給予漂白水 (Bleach) 、 BioGel或市售抗沾黏膠 (Seprafilm)。我們觀察小鼠子宮沾黏程度及進行小鼠子宮組織切片染色(Masson’s Trichrome stain及Picro-Sirus Red stain),我們發現BioGel可顯著降低手術引發的沾黏及組織纖維化,並且BioGel比市售抗沾黏膠 (Seprafilm) 的子宮纖維化程度較低。進一步以即時定量PCR定量纖維化指標基因的表達量,我們分析結締組織生長因子 (connective tissue growth factor, CTGF)、第一型膠原纖維 (collagen type 1, Col1a1) 和纖維蛋白原alpha鏈 (fibrinogen alpha chain, Fga)。另外,我們也定量發炎指標細胞介白素第六因子 (interleukin-6, Il-6) 和腫瘤壞死因子 (tumor necrosis factor, Tnf) 表達量,發現BioGel 複合水膠可以有效降低手術引發的組織纖維化及組織發炎相關基因表達量。並且也降低子宮周圍腹腔組織白血球浸潤。我們同時定量細胞增生指標Ki67表達量,發現BioGel 複合水膠可以有效保護子宮內膜細胞增生能力。於體內胚胎著床試驗中,我們發現僅Sham組胚胎順利著床。綜合上述結果顯示BioGel 複合型水膠具有抗沾黏及降低術後組織沾黏、發炎及子宮纖維化的功效。
