AIM: To evaluate the clinical effects of compound trabeculectomy for primary angle-closure glaucoma with persistent high intraocular pressure.
●METHODS:Thirty-three cases ( 34 eyes ) with primary angle - closure glaucoma were executed compound trabeculectomy. All patients were divided into two groups: group A: 18 cases ( 18 eyes ) were executed compound trabeculectomy under high intraocular pressure higher than 35mmHg after using lOP-lowering medicine for 48-72h; group B: 15 cases (16 eyes) were executed compound trabeculectomy, the intraocular pressure was normal after using lOP-lowering medicine.
●RESULTS:Thirty-four eyes were successfully completed surgery with follow-up of 6 to 18mo and there were no serious complications, including suprachoroidal hemorrhage. The visual acuity before operation in group A and group B were 0. 02 ± 0. 01, 0. 04 ± 0. 02, respectively. And the postoperative visual acuity in group A and group B increased 0.2±0. 06, 0. 3±0. 07, respectively (P<0. 01). All of them, intraocular pressure with 30 eyes were controlled in 9-23 mmHg, 3 eye was controlled by normal through adding in several kinds different lOP-lowering medicine. One eye was failure. Compared to preoperation, postoperative intraocular pressure of two groups were decreased by normal, which were 17. 9 ± 9. 1 mmHg and 15. 4±8. 4mmHg, respectively (P<0. 01). There was no significant difference between two groups for postoperative intraocular pressure.
●CONCLUSION: The primary angle-closure glaucoma with persistent high intraocular pressure should be executed compound trabeculectomy decisively, even under high intraocular pressure, which prevent further damage and loss of visual function. As long as to fully consideration the preoperation, intraoperative careful operation, careful nursing, it is safety and effective to have compound trabeculectomy under the continuous high intraocular pressure for primary angle-closure glaucoma.

Qualitative and quantitative analyses of biological samples containing drugs, toxicants and endogenous substances play an important role in the researches of life sciences, as well as in new drug discovery and development. Biological samples are characterized by complex matrix, multiple endogenous interferences, significantly lower concentrations of measured analytes compared to endogenous components and small sampling volume. Consequently, it often requires bioanalysis methods with superior specificity, high sensitivity and good reproducibility. The two-dimensional liquid chromatography (2D-LC) technique, which allows for high peak capacity, significant reduced matrix effect and carryover of complex matrix samples and automated sample pre-treatment and analysis, has been the powerful solution to the separation and analysis of biological sample and widely applied to environment, food and pharmaceutical analysis. On the basis of introduction of the principle and equipments of 2D-LC, the application of this technique in the pharmacokinetics, toxicological and biological study was reviewed.
