白内障术后晶状体后囊膜混浊(posterior capsular opacification,PCO)(后发性白内障)是现代白内障术后最常见的并发症,防治PCO是保障白内障手术远期疗效的关键.术中残留的晶状体上皮细胞增生、移行和上皮-间质转化是PCO形成的细胞学基础.转化生长因子β(transforminggrowth factor beta,TGF-β)通过正性调控晶状体上皮细胞的增生、迁移、转分化及凋亡等,促进了PCO的发生发展过程.设想可通过对TGF-β、TGF-β受体及其下游通路中的Smad蛋白和基质金属蛋白酶等进行干预来防治PCO.采用结膜囊涂抹及前房注射TGF-β抗体、基质金属蛋白酶抑制剂及结缔组织生长因子反义寡核苷酸或特异性抗体等将成为PCO防治的新途径.
白內障術後晶狀體後囊膜混濁(posterior capsular opacification,PCO)(後髮性白內障)是現代白內障術後最常見的併髮癥,防治PCO是保障白內障手術遠期療效的關鍵.術中殘留的晶狀體上皮細胞增生、移行和上皮-間質轉化是PCO形成的細胞學基礎.轉化生長因子β(transforminggrowth factor beta,TGF-β)通過正性調控晶狀體上皮細胞的增生、遷移、轉分化及凋亡等,促進瞭PCO的髮生髮展過程.設想可通過對TGF-β、TGF-β受體及其下遊通路中的Smad蛋白和基質金屬蛋白酶等進行榦預來防治PCO.採用結膜囊塗抹及前房註射TGF-β抗體、基質金屬蛋白酶抑製劑及結締組織生長因子反義寡覈苷痠或特異性抗體等將成為PCO防治的新途徑.

Posterior capsular opacification (PCO) is a most common complication of modem cataract surgery.The prevention of PCO is the key to ensure long-term efficacy of cataract surgery.The proliferation,migration,and epithelial-mesenchymal transition of intraoperative residual lens epithelial cells are cellular basis of PCO.Transforming growth factor β,(TGF-β) participates in the development of PCO by regulating lens epithelial cells proliferation,migration,differentiation and apoptosis.It is envisaged that the regulation of TGF-β,TGF-β receptor and its downstream pathway (Smad proteins and matrix metalloproteinases) can prevent PCO.By the means of conjunctival sac daub and anterior chamber injection,TGF-β antibodies,matrix metalloproteinase inhibitors and connective tissue growth factor antisense oligonucleotides or specific antibodies may become the new ways of preventing PCO.
