Objective To select microRNAs (miRNA) associated with human cutaneous malignant melanoma (MM). Methods Total RNA was extracted from 6 tissue samples of MM and 9 human control samples of pigmented nevi, and small RNAs of less than 200 bp were enriched, miRNA microarray was used to select differentially expressed miRNAs between tissue samples of MM and pigmented nevi from 468 candi-dates. The expression of differentially expressed miRNAs was confirmed by fluorescence based real-time quan-titative PCR (qPCR) in all of these samples. Those miRNAs that were identified as differentially expressed with both miRNA microarray and qPCR were considered as significant miRNAs. Results Between the tissue samples of MM and pigmented nevi, 12.18% to 86.33% of miRNAs differentially expressed by more than 2 folds, 1.28% to 19.02% by more than 5 folds, and 0.43% to 5.34% by more than 10 folds. The expression of miRNA-21 was obviously up-regulated, while that of miRNA-320 and miRNA-494 was down-regulated in the MM samples. Conclusion There is an increase in the expression of homo sapiens miRNA-21 but a decrease in that of miRNA-320 and miRNA-494 in MM tissues.

Objective To summarize the clinical results and safety of photodynamic therapy (PDT) through 4 years after single and multi-treatments of patients with subfoveal choroidal neovascularization (CNV) caused by age-related macular degeneration (AMD). Methods Clinical data of 73 AMD cases (95 eyes) diagnosed through fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optic coherence tomography (OCT), treated with PDT were reviewed and analyzed in this hospital from June 2000 to June 2004. The changes of best corrected visual acuity (BCVA), fundus pictures, FFA, ICGA and OCT were compared before and after PDT. Follow-up time varied from 3 months to 4 years (mean, 2 years). Results The mean age of 73 patients was 67.8 years old. The BCVA was from (CF/10 cm) to 1.0. At the final follow up, the BCVA was improved (increase≥2 lines) in 39 eyes (41.1%), stabilized (?1 line) in 51 eyes (53.7%) and decreased 2 lines in 5 eyes (5.3%). Fundus hemorrhage and exudation reduced after PDT. FFA and ICGA showed CNV complete closure in 58 eyes (61.05%), partial closure in 6 eyes (6.32%), CNV incomplete closure in 22 eyes (23.16%) and recurrence in 9 eyes (9.47%). After once PDT of 12 eyes with early-stage AMD, the BCVA improved (from 0.6 to 1.5), CNV completely closed, and the OCT showed disappearance of macular edema and neursensory retinal detachment. No CNV recurred in our four years follow-up observation and the BCVA of the patients remained stable. The mean number of PDT treatment was 1.8 per eye in 95 cases. No serious local or systemic complications were encountered. Conclusions Single or multiple sessions of PDT can acheive long-term safety and efficacy. For early-stage AMD patients with minimally classic CNV, PDT can completely make CNV closed and reduce the risk of visual loss.

Purpose To evaluate short term visual acuity effects of a single photodynamic therapy(PDT) treatment with Visudyne (CIBA Vision Corp, Duluth, Ga) for choroidal neovascularization (CNV) in age related macular degeneration (AMD). Methods Definitely diagnostic AMD patients with classic CNV were treated with PDT (5 cases, 7 eyes). The data of visual acuity testing, ophthalmic examination, color photographs, optic coherence tomography, fluorescein angiograms and indocyanine green angiogram before photodynamic therapy and 1 week ,1 month after it were used to evaluate the effects of a single treatment of PDT with Visudyne. Results The visual acuity of all the treated eyes at the follow up examination at 1 month after PDT were not reduced. Distinct reduction of fluorescein leakage from CNV was noted in all patients by 1 week after PDT. Fluorescein leakage from a portion of the CNV reappeared by 1 month after treatment in 2 eyes. Conclusion PDT with Visudyne achieved short term cessation of fluorescein leakage from CNV without loss of vision or growth of classic CNV in some patients with AMD.

Objective To study the clinical results and safty of photodynamic therapy (PDT) after single and multi treatments of patients with subfoveal choroidal neovascularization (CNV) caused by wet age related macular degeneration (AMD). Methods From July, 2000 to July, 2001, 20 wet AMD patients (31 eyes) 47 88 years old (mean 68.2 years old) with best corrected visual acuity from FC/10 cm to 0.6 diagnosed through optic coherence tomography (OCT), fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were treated with PDT. All cases were assigned to benzoporphyrin derivative mono acid (BPD) (6 mg per square meter of body surface area), administered via intravenous infusion of 30 ml over 10 minutes. Fifteen minutes after the start of the infusion, a laser light at 689 nm (Zeiss company, German) delivered 50 J/cm 2 at an intensity of 600 mW/cm 2 over 83 seconds on CNV. Visual acuity, photochrome of ocular fundus, OCT, FFA, ICGA were used to evaluate the effects of photodynamic therapy with BPD. Follow up of these patients was planned 1 2 week and every 3 month after PDT. Once the lesion area progressed, PDT was applied again. Tweenty cases (31 eyes) were followed up from 3 to 18 months (average 12 month).In 1 affected eye, PDT was applied fow 4 times, 4 eye for 2 times, and the other 26 eyes for 1 time. Results The visual acuity in 13 (41 9%) eyes was improved ( increase≥2 lines) after PDT. Stabilized (?1 line) in 17 (54 8%) eyes and decreased 2 lines (attributed to the recur of CNV ) in 1 (3 2%) eye. After PDT, the fundus haemorrhage and fluid leakage reduced. FFA and ICGA showed. cessation and obvious reduction of fluorescein leakage from CNV in all patients 2 weeks after photodynamic therapy, and retreatment decreased the leakage step by step. Fluorescein leakage from at least a portion of the CNV reappeared by 1 3 month after treatment in some cases. OCT also showed the reduction of the size of CNV, moreover, the edema of surrounding retina and choriodal and serous neural epithelial detachment recovered obviously. No side affect during and after PDT was noticed. Conclusions PDT with BPD can achieve short term effect on part or total cessation of fluorescein leakage from CNV without loss of vision or growth of classic CNV in patients with age related macular degeneration, retreatment of PDT was also effective.
