ABSTRACT
AIM: To observe the efficacy of surgical excision combined with autologous limbus conjunctival flap transplantation in the treatment of pterygium accompanied with conjunctival cyst.METHODS: Totally 126 patients 188 eyes with pterygium were hospitalized in Department of Ophthalmology of Tongji Hospital of Huazhong University of Science and Technology during August 2013 and August 2015.The patients were divided into two groups: observation group (11 eyes of 11 patients) with pterygium accompanied with conjunctival cyst and control group (177 eyes of 115 patients) with primary pterygium.All patients underwent slit lamp microscope examination, anterior segment photography, and anterior segment optical coherence tomography(OCT).The size of pterygium was calculated by multiplying neck width and length of the covered corneal.All patients underwent excision combined with autologous conjunctival flap transplantation, and the resections were performed pathological section with hematoxylin and eosin staining.All patients were followed up postoperatively for 4-28mo.RESULTS: All cases in the observation group were confirmed by postoperative pathological examination.All cyst walls were complete, and containing single layer of epithelial cells.The mean size of pterygium of the observation group was 6.9±1.7mm2, and 6.3±1.8mm2 for the control group.There was no significant difference between the two groups (P>0.05).The mean postoperative healing time of observation group was 2.1±0.9d, and 1.9±0.8d for the control group.There was no significant difference between the two groups (P>0.05).Recurrence was seen in two eyes within the follow-up period in the control group, and no recurrence in the observation group.CONCLUSION: Surgical excision combined with autologous limbus conjunctival flap transplantation is a safe and effective treatment for pterygium accompanied with conjunctival cyst.
ABSTRACT
We carried out this meta-analysis to assess the effects of renal denervation (RDN) on resistant hypertension patients. According to the collaborative review group search strategy, we searched MEDLINE (1996 to 2015.10); EBCO (1996 to 2015.10) and CNKI. A meta-analysis was carried out using RevMan 5.0. We identified 11 reports that fulfilled the inclusion criteria for our review. Controlled trials reporting systolic blood pressure (SBP), diastolic blood pressure in RDN, and control groups at the 6-month follow-up in patients with resistant hypertension were systematically reviewed. Pooled analysis of all 11 included studies showed significant reductions in SBP (weighted mean difference -13.9 mmHg, 95% confidence interval -21.17 to -6.63, P=0.00025, I=93%) and diastolic blood pressure (weighted mean difference -4.41 mmHg, 95% confidence interval -6.95 to -1.88, P=0.004, I=90%) compared with the control group at the 6-month follow-up. Six controlled trials reported specific values of ambulatory SBP that showed no significant difference between two groups. It has also been found that RDN has benefits in protecting cardiac and renal function compared with the control group without increasing adverse events. In conclusion, this meta-analysis shows that RDN is superior to the control group in lowering office blood pressure rather than ambulatory SBP, and might have other potential benefits to protect heart and renal function.

AIM: To evaluate the safety and efficacy of Ahmed glaucoma valve implantation for refractory glaucoma after sequential failed trabeculectomy. METHODS: Thirty - six patients (36 eyes) with prior failed sequential trabeculectomy who underwent Ahmed glaucoma valve implantation were included. The intraocular pressure ( IOP), best corrected visual acuity (BCVA) and complications were ovserved and all the patients were followed up at least for 12mo. RESULTS: Mean preoperative IOP was 35. 20±7. 28mmHg and reduced to 10. 15±3. 34, 11. 23±3. 56, 15. 63±5. 72, 17. 17±5. 47, 17. 73±6. 23,19. 76±5. 43mmHg at 1, 2wk, 1, 3, 6 and 12mo after surgery, which was significant different from the preoperative level (t = 12. 643, 11. 837, 10. 324, 8. 839, 8. 462, 8. 046, all P 0. 05). At 12mo after operation, the complete success rate reached 78% and the conditional success rate reached 92%. There were 5 eyes complicated with shallow anterior chamber, 3 eye complicated with anterior chamber hemorrhage, which all recovered after additional treatments. Late complications included valve exposure and encapsulated cystic blebs around the plate. Severe corneal endothelium loss occurred in 1 patient. CONCLUSION: Ahmed glaucoma valve implantation is effective in reducing IOP at 1-year follow-up in refractory glaucoma patients with prior sequential failed trabeculectomy, but we should fully understand and attach great importance to all kinds of complications that may occur.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the qualifications and current situations of the medical and health institutions and certified doctors for providing occupational disease diagnosis in China and to provide a reference for developing relevant policies.</p><p><b>METHODS</b>Work reports and questionnaires survey were used to investigate the qualifications of all medical and health institutions and certified doctors for providing occupational disease diagnosis in China and their acceptance and diagnosis of occupational disease cases from 2006 to 2010. The rate for the work reports was 100%, and the response rate for the questionnaires was 71.0%.</p><p><b>RESULTS</b>By the end of 2010, in the 31 provincial-level regions (excluding Hong Kong, Macao, and Taiwan) in China, there had been 503 medical and health institutions which were qualified for providing occupational disease diagnosis, including 207 centers for disease control and prevention, accounting for 41.2%, 145 general hospitals, accounting for 28.8%, 69 enterprise-owned hospitals, accounting for 13.7%, and 64 institutes or centers for occupational disease prevention and control, accounting for 12.7%; 4986 certified doctors got the qualification for providing occupational disease diagnosis, with 9.4 certified doctors on average in each institution, and there was 0.65 certified doctor per 100 000 employees. In addition, 16.5% of the institutions got all the qualifications for diagnosing 9 occupational diseases, and 17.1% of the institutions got the qualification for diagnosing one occupational disease. Each certified doctor accepted diagnosis of 16.8 cases of occupational diseases on average every year.</p><p><b>CONCLUSION</b>A national occupational disease diagnosis network has been established in China, but the imbalance in regional distribution and specialty programs still exists among the qualified medical and health institutions and certified doctors. It is essential to further strengthen the development of regional qualified medical and health institutions and training of qualified doctors.</p>
