Although RoyCamile, Dick, Steffee, R-F etc., are all different surgical procedures, all need pedical screwtechniques. Up to March 1991, 61 cases with 334 screws inserted by Steffee and Dickoperations had been performed in our hospital. Neurological symptoms, among allcomplications , are the most serious problems assoclated with these procedures. By ahalyzingthe insertion point, transverse screw angle, sagittal angle and other causes of complicationsof pedicle screws, we present here our experiences for prevention and treatment of thesecomplications.展开更多

The results showed that salivary β2m concentration was more significantly elevated in Sjogren’s syndrome patients, compared with that in both normals and other patients. The measurement of β2m concentration in saliva may offer a simple and valuable method for diagnosis of Sjogren’s syndrome.展开更多
