AIM： To assess the efficacy and safety of patterned laser trabeculoplasty（PLT） as an adjunctive treatment in open angle glaucoma（OAG） or ocular hypertension（OHT） patients who were under antiglaucoma medical ***： This study was a retrospective review of primary or secondary OAG patients and OHT patients with medically uncontrolled（≥18 mm Hg） intraocular pressure（IOP） who underwent 360o PLT from June 2016 to August 2016. Follow-up visits at week 1, and 1, 3 and 6 mo were performed. IOP, best corrected visual acuity（BCVA）, complications and eye drop glaucoma medication were recorded at each follow-up visit. Success was defined as IOP reduction ≥20% from baseline. RESULTS： Forty-one eyes of 25 patients were included in this study. Pre-treatment mean IOP was 20.2±1.6 mm Hg. After PLT, IOP was 19.3±5.2, 16.1±2.7, 17.1±3.7 and 16.3±3.5 mm Hg,at 1 wk, 1, 3 and 6 mo, respectively. IOP reduction from baseline was statistically significant from the first month, remaining stable at 6 mo（P〈0.001）. PLT success at 6 mo of follow-up was 48.78%. The number of glaucoma medication per eye（P=0.10） and the mean BCVA both remained constant（P=0.37）. Complications included transient IOP spikes in 4 eyes（9.8%） and peripheral anterior synechiae in 7 eyes（17.1%）. CONCLUSION： PLT is an effective and safe method for the management of patients with OHT or OAG as an adjunctive therapy. Additional larger studies should be designed to verify the long-term stability of IOP reduction with this laser technology.

Neoadjuvant Radiotherapy in Stage I Cancer of the Lower Rectum

Journal of Cancer Therapy 2014年第6期5卷 560-564页

Introduction: The mortality rate in cancer of the lower rectum is related to the incidence of local recurrence, in the first 5 years. For stage I tumors, local excision has being increasingly used, but recent studies showed a higher incidence rate of local recurrence. Therefore, preoperative radiotherapy should be considered even for these tumors, as an attempt to prevent recurrence and provide cure. Objective: To show the effectiveness of neoadjuvant radiotherapy in stage I cancer of the lower rectum of a cohort population. Materials and Method: A cohort study in a prospective database was made with a total of 75 patients considered as stage I cancer of the lower rectum. Preoperative long course of 4500 cG radiotherapy was performed in this selected group of patients and followed up for a minimum period of five years. Results: Stage I/TI group had 27 patients. All of them presented complete response to the treatment and did not need to be submitted to surgery. Five years follow up with no recurrence. The stage I/TII group had 48 patients. After neoadjuvant radiotherapy, 8 patients had to be submitted to surgery for persistent tumor. All were submitted to full total local excision (FTLE), but anatomopathological examination showed no residual cancer. Conclusion: Preoperative long course of 4500 cG irradiation, not only reduced the local recurrence and mortality rate in lower rectal cancer, but also reduced indication for surgery in patients with stage I cancer of the lower rectum.

Antioxidant Enrichment and Antimicrobial Protection of Fresh-Cut Mango Applying Bioactive Extracts from Their Seeds By-Products

Food and Nutrition Sciences 2013年第8期4卷 197-203页

The effect of the application of ethanolic extract of “Haden” mango seeds to increase the antioxidant and antimicrobial capacity of fresh-cut mango flesh was evaluated. Phenolic HPLC analysis revealed that gallic acid was the major identified compound in the ethanolic extract (586.68 mg/g). Fresh-cut mango was treated for immersion within the ethanolic extract, packed and stored at 5℃ during 15 days. The content of phenolic compounds, antioxidant capacity and microbial growth of the treated mango were evaluated during the storage. Compared with the controls the treated fruit presented the highest content of the total phenolic (7.4 times), flavonoids (3.1 times), and antioxidant capacity DPPH·, TEAC and ORAC (2.9, 2.3 and 2.8 times, respectively), and showed a microbial reduction of 80% of mesophilic plate count and 97% of total molds. This study demonstrates the potential of phenolic compounds derived from mango seed as antimicrobials and antioxidants.
