RESUMO
AlM: To compare the effects of external approach microsurgery and conventional external approach surgery for retinal detachment ( RD) .METHODS: From January 2010 to January 2013, 60 patients (60 eyes) in our hospital were randomly divided into experimental group (29 cases, 29 eyes) and control group ( 31 cases, 31 eyes ) , the external approach microsurgery and conventional external approach surgery were performed respectively ( by the same skilled doctor ) . Retinal reattachment rate, visual acuity improvement rate and operative time were compared between two groups.RESULTS:lt cost shorter time for the external approach microsurgery than that of conventional external approach surgery ( P = 0. 0087 ). The once successful retinal reattachment rate in experimental group was 93% ( 27 cases ) , which was higher than that in control group (90%, 28 cases), there was no statistical difference. The vision improvement rate in control group was 86% ( 25 cases ) , compare to 90% ( 28 cases ) in experimental group, there was no statistical differences. CONCLUSlON: No statistical differences showed in visual acuity improvement and the once retinal reattachment rate between the two groups for rhegmatogenous retinal detachment. However, it is believed that external approach microsurgery could be faster, easier to learn with satisfactory effect.
RESUMO
OBJECTIVE@#To investigate the effect of mycophenolate mofetil(MMF) on early inflammatory reaction of renal lesion in streptozotocin(STZ)-induced diabetic rats.@*METHODS@#Thirty-six male Sprague-Dawley rats were randomly divided into 3 groups after uninephrectomy: normal control group, diabetic model group, and MMF-treated group. Six rats in each group were sacrificed at the 4th week and 14th week after STZ injection. Twenty-four hour urinary protein (24 h Upro) count was measured before death. The expressions of regulated on activation of normal T expressed and secreted (RANTES),ectodermal dysplasia (ED-1)and Col-IV protein in the renal tissue were detected by immunohistochemistry. The expression of RANTES mRNA in the renal tissue was detected by RT-PCR.@*RESULTS@#MMF prevented the increasing of 24h Upro in diabetic rats,and the expressions of RANTES,ED-1,Col-IV protein and RANTES mRNA in the kidney of MMF-treated rats were significantly decreased.@*CONCLUSION@#MMF plays an early renal protective role in diabetic nephropathy, possibly through inhibition of early inflammatory reaction.
