?AIM:To observe the clinical effect of Ahmed glaucoma valve ( AGV ) implantation for teenagers with refractory glaucoma.?METHODS: Twenty-seven patients ( 27 eyes ) with refractory glaucoma were treated with AGV implantation in our hospital from October 2012 to October 2014. The patients were followed up for 12mo. The success rate of the operation, postoperative intraocular pressure, the best corrected visual acuity, as well as complications were recorded.?RESULTS:The success rate of the operation was 85%. The intraocular pressure of the 27 patients decreased from 48. 3 ± 8. 3mmHg before operations to 21. 4 ± 8. 1mmHg(P<0. 05). Visual field defect was -23. 7±4. 1dB before operations, - 27. 5 ± 4. 7dB at 12mo after operations, and the difference was statistically significant (P<0. 05). There was 85% patients with improved or unchanged vision. Early postoperative complications included shallow anterior chamber ( 5 eyes, 19%) , transient high intraocular pressure ( 3 eyes, 11%) and anterior chamber hemorrhage ( 4 eyes, 15%) , drainage tube obstruction (1 eye, 4%), anterior chamber silicone tube in poor position ( 1 eye, 4%) . There was no ambiopia, drainage erosion and exposed, plate leaked out, choroidal detachment, immune rejection of graft and other complications. Long - term complications included dyscoria ( 8 eyes, 30%) , the back of the plate packed(3 eyes, 11%).?CONCLUSION:AGV implantation is characterized by a high success rate, simple operation, less complications and is an effective treatment for refractory glaucoma in adolescents.

This study is to investigate the effects of paeoniflorin on cerebral blood flow and the balance of PGI2/TXA2 of rats with focal cerebral ischemia-reperfusion injury. A total of 72 SD rats (3) were randomly divided into 6 groups: sham operation group, cerebral ischemia-reperfusion model group (I/R gourp), low (10 mg.kg-1), middle (20 mg.kg-1) and high (40 mg.kg-1) doses of paeoniflorin groups and nimrnodipine group. Focal cerebral ischemia in rats was made by inserting a monofilament suture into internal carotid artery for 90 min and then reperfused for 24 h. The effects of paeoniflorin on neurological deficit scores and the infarction volume of brain were detected. Relative regional cerebral blood flow (rCBF) was continuously monitored over ischemic hemispheres by laser-Doppler flowmetry (LDF). The expression of COX-2 in hippocampal CAl region was estimated by immunohistochemistry and the contents of prostacyclin I2 (PGI2), thromboxane A2 (TXA2), and ratio of PGIJ2/TXA2 in serum were measured by ELISA kits. Paeoniflorin significantly ameliorated neurological scores, reduced the infarction volume, and increased regional cerebral blood flow relative to the I/R group. In addition, paeoniflorin could inhibit COX-2 expression and the release of TXA2 and prevent the downregulation of PGI2 induced by I/R injury. The neuroprotective effects of paeoniflorin against focal cerebral ischemia-reperfusion rats might be attributed to improve the supply of injured hemisphere blood flow and adjust the balance between PGI2/TXA2.
