A novel chelate Eu(TTA) 2(PMTBBP)Phen, which contained ligand 1 pheny 3 methyl 4 (4 t butylbenzoyl) 5 pyrazolone(HPMTBBP), 4,4,4 trifluro 1 (2 thienyl) 1,3 butandione(HTTA) and phenanthroline(Phen), was synthesized....A novel chelate Eu(TTA) 2(PMTBBP)Phen, which contained ligand 1 pheny 3 methyl 4 (4 t butylbenzoyl) 5 pyrazolone(HPMTBBP), 4,4,4 trifluro 1 (2 thienyl) 1,3 butandione(HTTA) and phenanthroline(Phen), was synthesized. Its chemical structure was elucidated by IR, UV, 1H NMR, MS, DSC and elementary analysis. The influence of acylpyrazolone on fluorescent intensity of the new chelate was studied. The results showed that Eu(TTA) 2(PMTBBP)Phen had more excellent PL properties and better film formation than that of Eu(TTA) 3Phen. [WT5HZ]展开更多
目的：评价术前栓塞联合手术治疗脑膜瘤的临床疗效。方法收集我院2004年6月～2014年4月间行全脑血管造影的脑膜瘤共112例，分为栓塞组（48例）和非栓塞组（64例），比较两组间的出血量、输血量、全切除率及手术时间。结果与非栓塞组相...目的：评价术前栓塞联合手术治疗脑膜瘤的临床疗效。方法收集我院2004年6月～2014年4月间行全脑血管造影的脑膜瘤共112例，分为栓塞组（48例）和非栓塞组（64例），比较两组间的出血量、输血量、全切除率及手术时间。结果与非栓塞组相比，栓塞组的术中失血量和输血量均显著减少（P ＜0．05），肿瘤的全切除率显著增高（P ＜0.05）；而在手术时间方面无统计学意义（ P ＞0．05）。结论术前栓塞可减少术中出血，并有助于提高脑膜瘤全切除率。展开更多
