Objective To explore the effect of preventing adhesion after the orbital blowout fracture on orbit tissue by amniotic membrane. Design Experimental study. Participants Twenty-six New Zealand rabbits. Methods Establishing rabbit orbital blowout fracture model, the right orbit of twenty rabbits was repaired by hydroxyapatite (HA) parceled of amniotic membrane, and left orbit was only repaired by HA, the orbits of the other six rabbits weren't repaired. Then we got the tissue around bone after one week and one month, and compared the difference of three groups. Main Outcome Measures Inflammatory response of tissue around bone was ana- lyzed by HE, picric acid Sirius Scarlet dying, TGF-?immunohistoehemical observation. Results One week after operation, HE and im- munohistochemistry showed that the difference was not significant in inflammatory response between experimental group and control group (P=0.351, P=0.413), and difference is significant between blank group and experimental group (P=0.012, P=0.041). One month after operation, HE and immunohistoehemistry showed that the difference was significant in inflammatory response between experimental group and control group(P=0.037, P=0.048), and there is no significant difference between experimental group and blank group(P=0.285, P=0.472). Conclusion It has an important role of anti-inflammatory and anti-adhesion in the chronic stage of inflammatory after orbital blowout fracture repaired by man-made plates of amniotie membrane.

AIM: To study the effects of resveratrol on the proliferation of human retinal vascular endothelial cells induced by cobalt chloride-simulated hypoxia in vitro.METHODS: CoCl2 (100μmol/L) was used to simulate hypoxic condition, and human retinal vascular endothelial cells were cultured in vitro as model. The cell proliferation was determined by MTT method; SABC method was employed to test the expression of vascular endothelial growth factor (VEGF); and computer image analyzer was used to process data. The effects of resveratrol on the proliferation of vascular endothelial cells were observed.RESULTS: Resveratrol inhibited the proliferation of human retinal vascular endothelial cells induced by CoCl2 in a dose- and time-dependent manner in vitro, meanwhile VEGF expression in all groups which were administered medicine was down-regulated. Both kinds of inhibitive effects of resveratrol were statistically significant (P<0.01).CONCLUSION: Resveratrol can significantly inhibit the proliferation of human retinal vascular endothelial cells and the expression of VEGF, which may provide a new approach for prevention and treatment of retinal neovascular diseases.
