摘　　要：AIM： To investigate the expression differences of transforming growth factor-β2（TGF-β2）, basic fibroblast growth factor（b FGF） and intercellular cell-adhesion molecule-1（ICAM-1） in lens epithelial cells（LECs） of complicated cataract with silicone oil tamponade and agerelated cataract. METHODS： Totally 150 eyes of 150 patients（aged 35 to 77y） were investigated, including 75 patients with complicated cataract after silicone oil tamponade and 75 patients with age-related cataract. The central piece of anterior capsules was collected during cataract surgery. TGF-β2, b FGF and ICAM-1 were detected in the 60 specimens of the two groups by immunohistochemistry. The expression levels of the three kinds of messenger ribonucleic acid（m RNA） were determined by real-time quantitative reverse transcriptionpolymerase chain reaction in the 90 specimens of the two groups.RESULTS： TGF-β2 was detected in the cytomembrane and cytoplasm of the LECs and b FGF was detected in the nucleus. ICAM-1 was positive in the cytomembrane of the LECs and the distribution of positive cells was uneven. The m RNA genes expression of the TGF-β2, b FGF and ICAM-1 was significant differences between the two groups and markedly increased in complicated cataract group（P〈0.05）.CONCLUSION： The up-regulated TGF-β2, b FGF and ICAM-1 maybe associate with the occurrence and development of complicated cataract with silicone oil tamponade.AIM： To investigate the expression differences of transforming growth factor-β2（TGF-β2）, basic fibroblast growth factor（b FGF） and intercellular cell-adhesion molecule-1（ICAM-1） in lens epithelial cells（LECs） of complicated cataract with silicone oil tamponade and agerelated cataract.
