Bis[4-(2-hydroxybenzylideneamino)benzoato-κO 1]tetrakis(methanol-κO)cadmium
In the title mononuclear complex, [Cd(C14H10NO3)2(CH3OH)4], the Cd2+ cation is situated on an inversion centre. It exhibits a distorted octahedral coordination, defined by two carboxylate O atoms from two monodentate anions and by four O atoms from four methanol molecules. The crystal structure comprises intramolecular O—H⋯O and O—H⋯N, and intermolecular O—H⋯O hydrogen bonds. The latter help to construct a layered structure extending parallel to (100)
Bis[2-(2-furyl)-1-(2-furylmethyl)-1H-benzimidazole-κN 3]diiodidocadmium
In the title complex, [CdI2(C16H12N2O2)2], the CdII atom is located on a twofold rotation axis and is four-coordinated by two N atoms from symmetry-related 2-(2-furyl)-1-(2-furylmethyl)-1H-benzimidazole ligands and two I atoms in a distorted tetrahedral configuration. The benzimidazole rings in adjacent molecules are parallel, with an average interplanar distance of 3.486 Å. The I atom is disordered over two sites in a 0.85 (5):0.15 (5) ratio
Comparison of the short term therapeutic effects by different incision triple surgery in treating angle-closure glaucoma with cataract
AIM:To compare the therapeutic effects of different incision phacoemulsification with foldable intraocular lens implantation combined with trabeculectomy in treating angle-closure glaucoma complicated with cataract. <p>METHODS: The retrospective study analyzed 70 patients(98 eyes)who performed phacoemulsification with foldable intraocular lens implantation combined with trabeculectomy. Single incision surgery(one-site approach)was performed on 34 patients(50 eyes), and double incision surgery(two-site approaches)was done on 36 patients(48 eyes). The differences of intraocular pressure control,filtering bleb, the density and preservation of corneal endothelium cells both pre-surgery and 1 month post-surgery or later complication. in the two groups were compared and analyzed.Follow-up was 12-24 months with a mean of 18.2 months.<p>RESULTS: The average postoperative intraocular pressure in one-site groups was(10.16±4.31)mmHg. The average postoperative intraocular pressure in two-site groups was(11.38±3.55)mmHg. There were no statistically significant differences between the two groups(<i>P</i>>0.05)regarding the postoperative intraocular pressure and the formation of filtering blebs(<i>P</i>>0.05). The density and area of corneal endothelium cells in the two-incision group pre-operation were comparable(<i>P</i>>0.05). However, in 1 month post-operation, the rate of the corneal endothelial cells loss in double incision group was superior compared to the single incision group(<i>P</i><0.01).<p>CONCLUSION: Both single incision and double incision approach phacotrabeculectomy are effective in reducing intraocular pressure and can maintain the function of filtering blebs well. There are no statistically significant differences in the intraocular pressure reduction between the two approaches. The double incision approach is superior in minimizing the corneal endothelial cells loss compared to the single incision approach
