International Eye Science 2016;16(6):1168-1170
?AIM: To explore the application of 25G vitreous cavity perfusion in phacoemulsification for cataract after vitrectomy.?METHODS:Forty-eight patients (50 eyes) with cataract after pars planavitrectomy in our hospital from September 2013 to September 2014 were selected to receive phacoemulsification and implantation of artificial lens with 25G vitreous cavity perfusion. Best corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) , postoperative discomfort, healing of scleral puncture and postoperative complications were observed.?RESULTS: All patients underwent surgery successfully. Compared to before operation, there was less patients with BCVA ≤0. 1, more patients with BCVA 0. 3-0. 5,>0. 5,>0. 3 (P<0. 05). The visual acuity of 1 eye decreased because of vitreous hemorrhage caused by original fundus lesion recurrence. The mean IOP before operation and at 1, 7d, 6mo after operation were 14. 67±0. 62mmHg, 14.75±0.56mmHg, 14.86±0.58mmHg, 14.88±0.59mmHg, respectively. There were no statistically significant differences of IOP between that before operation and those at 1, 7d, 6mo after operation (P>0. 05). No obvious eye discomfort and severe complications after operation were observed.? CONCLUSION: The effect of 25G vitreous cavity perfusion in phacoemulsification for cataract after vitrectomy is good and it can maintain IOP, keep anterior chamber stable and decrease the complications risk.

7.UV-B Irradiation Regulates Apoptosis in Yeast
Microbiology 1992;0(06):-
Mechanisms of UV-B-induced apoptotic regulation in yeast Saccharomyces cerevisiae were studied. The results showed that UV-B irradiation indeed inhibited the growth of yeast cells as well as induced extensive apoptosis during 96 h experiment period. However, survival of 96 h irradiated cells remained 10% while most control cells finally dead after re-growth under UV-B irradiation for 12 d. And by exposed to 0.01 mol/L or 0.1 mol/L H2O2 for 30 min, survival rate of 24 h irradiated cells were 3.0-fold or 3.2-fold than control, respectively. By to heat shock for 30 min or 60 min, survival rate of 24 h irradiated cells were 3.5-fold or 9.0-fold than control, respectively.
