AIM:To explore and compare effect of coaxial micro-incision phacoemulsification and standard coaxial phacoemulsification in the treatment of cataract.
METHODS:A total of 88 patients(88 eyes) with senile cataract who underwent selective cataract ultrasonic emulsification resorption combined with intraocular lens implantation in the hospital from Aug. 2013 and Aug. 2015 were selected, they were divided randomly into the control group ( 44 cases, 38 cases completed, 6 cases dropped out ) and the observation group ( 44 cases, 40 cases completed, 4 cases dropped out ) . The control group received standard coaxial 3. 0mm small incision phacoemulsification, the observation group received coaxial 1. 8mm micro-incision phacoemulsification. All patients were combined with intraocular lens implantation. Intraoperative effective ultrasonic time, cumulative release energy, best corrected visual acuity before and after surgery in the two groups were recorded, corneal endothelium cell population, incision corneal thickness, percentage of cornea hexagon cell, corneal astigmatism changes before the operation, 1d, 7d, 30d after the operation were compared.
RESULTS: There was no significant difference in intraoperative effective ultrasonic time, cumulative release energy in the two groups(P>0. 05). There was no significant difference in postoperative best corrected visual acuity between the two groups(P>0. 05). Corneal endothelium cell population, percentage of cornea hexagon cell 1d, 7d, 30d after the operation in the two groups were significantly decreased compared with those before the treatment ( P < 0. 05 ), but there was no significant difference in the two groups ( P > 0. 05 ). Incision corneal thickness 30d after the operation in the observation group was significantly lower than the control group(P<0. 05). Degree of corneal astigmatism in the observation group 1d, 7d, and 30d after the operation were significantly lower than the control group (P<0. 05).
CONCLUSION: Coaxial micro - incision phacoemulsification and standard coaxial phacoemulsification can improve visual acuity of cataract patients, but the former can reduce degree of corneal astigmatism.

Objective:To study the inhibitory effect of siRNA on Heparanase (HPA) expression in SKOV3 cells. Methods:Two pairs of 21 bp reverse repeated sequence targeting HPA RNA (spaced by 9 bp nueleotide) were synthe- sized and were cloned into plasmid PGenesil-1 to construct recombinant plasmid PGenesil-1(+)-HPA expressing 2 hair- pin siRNAs.The inhibition of HPA gene was detected by RT-PCR,real-time PCR and immunohistochemical staining after PGenesil-1(+)-HPA was stably transfected into SKOV3 cells.Results:The recombinant plasmid PGenesil-1(+)-HPA (expressing 2 hairpin siRNAs) was successfully constructed.RT-PCR,real-time PCR and immunohistochemical staining showed that there was a significant decrease in HPA mRNA and protein level in experimental group compared with those in control group.Conclusion:siRNA targeting HPA mRNA can specically suppress the expression of HPA gene in SKOV3 cells;RNA interference method provides a new way for studying the role of HPA and gene therapy of cancer.

Three candidate antisense target sites of mouse Fas gene were screened by PARASS (poly-A anchored RNA accessible sites screening) technology. They were target at Fas gene 297nt-317nt, 618nt- 638nt and 662nt-682nt. Antisense oligos (A1, A2 and A3) and DNAzymes (D1, D2, and D3) for every target site were designed and synthesized. In vitro, the validation of the sites were judged by antisense oligos included RNase H splicing and the DNAzyme degradation. The results indicated that A1, A2 and A3 introduced RNase H degradation. DNAzymes D1, D2 and D3 cleaved Fas mRNA effectively. Neither degradation observed in antisense oligo RNase H group in non-target site (1211-1231nt) and 2 bases mismatched of A3, nor splicing occurred in DNzyme group in non-target site ( 1211-1231nt) and 2 bases mismatched of D3. Site 2 and 3 were at the same positions with those of ISIS Pharmaceuticals. The effective antisense oligos and DNAzymes for Fas gene could be used for the research subsequently.
