RESUMEN
@#AIM: To evaluate the clinical outcomes of phacoemulsification in patients with Fuchs' heterochromic iridocyclitis(FHIC). <p>METHODS: In this noncomparative case series,18 eyes of 18 patients clinically diagnosed with FHIC and cataract were studied. All of them received phacoemulsification combined with intraocular lens implantation.Preoperative and postoperative visual acuity, intraocular pressure, corneal endothelial cells density were measured. Intraoperative and postoperative complications were evaluated. <p>RESULTS: The mean follow-up period was 9.8±3.3mo. The only intraoperative complication was peripheral iris bleeding(17%). Compared with preoperative, the best corrected visual acuity improved 6mo postoperatively(0.98±0.85 <i>vs</i> 0.08±0.14, <i>P</i><0.001). There was no significant difference in intraocular pressure between preoperative and postoperative(15.11±2.63mmHg <i>vs</i> 14.94±2.49mmHg, <i>P</i>>0.05).The mean endothelial cells counting loss rate postoperatively was 10%±6%. Fibrin formation in the anterior chamber occurred in 2 eyes postoperatively. During follow-up, 1 eye developed anterior capsule contraction, and 4 eyes developed posterior capsule opacification. <p>CONCLUSION: Phacoemulsification is a safe procedure with good visual outcomes in patients with FHIC and cataract.
RESUMEN
Objective To investigate the expressions of interleukin-8 (IL-8) mRNA and proliferating cell nuclear antigen (PCNA) protein in astrocytic tumors and their correlation with the tumor cell apoptosis. Methods The expressions of IL-8 mRNA in 64 cases of astrocytic tumor and 10 normal brain tissues were detected using RT-PCR. The expression of PCNA protein in the tumors was assayed with immunohistochemistry, and the apoptosis index (AI) of the tumor cells determined using TUNEL assay. Results The expression ofIL-8 mRNA in the astrocytic tumors was strongly correlated to the malignancy of the tumors, and both the PCNA expression and the apoptosis index increased in tumors of greater malignancies. IL-8 mRNA expression was positively correlated to the expression of PCNA (r=0.938, P<0.01) and AI (r=0.907, P<0.01) in these tumors. Conclusion IL-8 mRNA expression is positively correlated to the histological grade of the astrocytic tumors, whose proliferation is mediated by inhibition of cell apoptosis and upregulation of IL-8 transcription.
