Methods: Retrospective analysis of 17 cases of elderly patients with Anderson II odontoid fracture who underwent posterior pedicle screw fixation combined with iliac bone grafting from January 2013 to December 2016. 17 patients had a history of trauma before surgery, and they all have varying degrees of atlantoaxial instability or subluxation and varying degrees of neck occipital pain and limited mobility. Result: No spinal cord or vertebral artery injury occurred during surgery. Follow-up information is complete. The follow-up period was 6 to 48 months (mean 27.4 ± 12.4 months). Postoperative imaging review prompted a good reduction of cervical spine, stable sequence;no pedicle screw loosening, fracture, iliac bone graft at the location of the situation, odontoid fracture and bone healing at the good, the patient after cervical rotation are limited to varying degrees. Conclusion: Posterior pedicle screw fixation combined with iliac bone grafting in elderly patients with Anderson II odontoid fracture can achieve good stability, and the prognosis is good, but long-term cervical rotation function may be affected to varying degrees.展开更多
A novel chiral polyoxometalate（POM）, {[Na（Arg）2]NaH}[AIMo6（OH）6O18].6H2O（1,Arg=L-arginine）has been synthesized by the reaction between Na3[A1Mo6（OH）6O18].8H2O and Arg in aqueous solution and was structu- ral...A novel chiral polyoxometalate（POM）, {[Na（Arg）2]NaH}[AIMo6（OH）6O18].6H2O（1,Arg=L-arginine）has been synthesized by the reaction between Na3[A1Mo6（OH）6O18].8H2O and Arg in aqueous solution and was structu- rally characterized by single-crystal X-ray diffraction, elemental analyses and UV-Vis spectrometry. Compound 1 was an example of Arg based Anderson-type complex. Photocatalytic analysis indicates that compound 1 presents cata- lytic activity for photodegradation of rhodamine-B（RhB） under UV irradiation.展开更多
