Role of human plasma fibronectin in the repair of the refractory corneal epithelial defect / 中国组织工程研究

ABSTRACT

BACKGROUND: Fibronectin(FN) plays the role of repair in the inflammation. There is no confirmed conclusion whether it can be applied to the refractory corneal epithelial defect.OBJECTIVE: To observe the repair effect of the human plasma FN for the refractory corneal epithelial defect.DESIGN: A controlled experimental study.SETTING: Guangzhou Red Cross Hospital, Guangzhou First People's Hospital, Guangzhou Children's Hospital, Guangzhou Hospital of Traditional Chinese Medicine and Guangzhou Second People's Hos pital.PARTICIPANTS: Totally 383 eyes with the refractory corneal epithelial defect were chosen, of which 309 were in the therapy group, and 74 in the control group.METHODS: The therapy group: Human plasma FN was administered by dropping it into the eyes once every two hours. The controlgroup: 10 g/L celacol M was administered by its dribbling into the eyes once every two hours. Weilesheng was taken orally in both groups, two pills once, three times per day. According to the state of illness, both groups received anti-bacterial or anti-viral treatment and reexamination was given every day or every other day after administration. 10 g/L fluorescein sodium was used to observe the changes of cornea.MAIN OUTCOSE MEASURES: The symptoms, results of staining using fluorescein sodium as well as the corneal epithelial healing of both groups.RESULTS: The symptoms, the results from staining using the fluorescein sodium and the corneal epithelial healing were used for the evaluation. In the therapy group, 309 eyes were followed up and the cure rate was 69.9%. The average therapeutic period was 6.5 days, while those of the control group were 58.1% and 8.7 days respectively. The difference in the curative effect between the two groups was significantly different( P＜0.01 ).CONCLUSION: The application of FN for the refractory corneal epithelial defect displays a more significant effect than conventional treatment.
