The sorption behavior and microscopic sequestration mechanisms of radionuclide 63Ni（II） on mordenite as a function of aging time, ionic srength, initial 63Ni（II） concentrations, solid content and coexistent electrolyte ions were investigated by the combination of batch and EXAFS techniques. Macroscopic experiment results show that the sorption of 63Ni（II） is dependent on ionic strength at pH〈7, and independent of ionic strength at pH〉7. The sorption percentage of 63Ni（II） on mordenite increases with increasing solid content, while the sorption capacity decreases as solid content increases. The presence of different electrolyte ions can enhance or inhibit the sorption of Ni（II） on mordenite in various degrees. EXAFS analysis results of the sam- ples under three different ionic strengths suggest that the retained 63Ni（II） in these samples exists in an octahedral environment with six water ligands. In the initial period of rapid uptake, the sorption of 63Ni（II） is dominated by the formation of innersphere surface complexes. As aging time increases, 63Ni（II） sequestration behavior tends to be mainly controlled by the formation of Ni phyllosilicate coprecipitates and/or Ni（OH）2（s） precipitates. Results for the second shell fit of the sample prepared at an initial 63Ni（II） concentration of 100 mg/L indicate the possible formation of Ni polynuclear surface complexes. Both the macroscopic sorption data and the molecular level evidence of 63Ni（II） surface speciation at the mordenite/water interfaces should be factored into better predictions of the mobility and bioavailability of 63Ni（II） in environment mediums.

Venous compression in microvascular decompression for idiopathic hemifacial spasm

第十四届中国医师协会神经外科医师年会

作者： Li Zhang Wenqiang Yang xiaoli xu Jun xu Yanbing Yu Department of Neurosurgery China-Japan Friendship Hospital

Objective To study the management of venous compression in microvascular decompression(MVD) for idiopathic hemifacial spasm(HFS). Methods From November 2006 to November 2010, 415 procedures of MVD were performed for the treatment of HFS in our department. The veins passing through the nerve root exit/entry zoons(REZ) of the facial and vestibulocochlear nerves were found in 29(7.0%) cases. The veins were believed to be the offending vessels except arterial compression in 8 cases(1.9%), 7 veins were coagulated and cut off, one was taken away from REZ by a Teflon prothesis. The other 21 veins were not believed to be the offending vessels and were neglected. Results The immediate effective rate of all the patients was 72.3%(300/415). In venous compression group, the rate was 96.6%(28/29). The effective rates of all the patients and venous compression group during follow-up period(2-6 years, mean duration: 4 years) were 97.9% and 100% respectively. There was one case of delayed resolution(the disappearance of spasm was observed in the 3week after operation). There was no recurrence in the venous compression group. The total recurrent rate of all patients was 2.2%(9/415). The postoperative complications of 8 cases with venous compression included: 2 cases of transient mild to moderate facial palsy, decreased hearing ability and tinnitus;one case of transient tinnitus;one case of transient mild facial palsy. The total rate of postoperative complication was 50%(4/8). Conclusions When the venous compression is observed and confirmed during MVD for HFS, the offending vein(s) should be coagulated and cut off to achieve complete decompression, but this procedure is always difficult and dangerous, which could result in higher rate of postoperative complications of facial and vestibulocochlear nerves. The veins passing between REZs of facial and vestibulocochlear nerves are not offending vessels and should be neglected. There is always an arterial compression except the venous co
