Objective To assess overall diagnostic value of SELDI-TOF-MS in early breast cancer. Methods To search and identify the relevent articals in English and Chinese from Jan. 1999 to Dec. 2007 on Medline,WeiPu full-text data base and Wan-Fang clara base, and the literatures have been integrated to review the quality rating, and the heterology examination and the meta analysis were conducted. While the summary receiver operating characteristic curve (SROC), pooled sensitivity, specificity and odds rate were calculated by SPSS13.0 software. Results 22 pertinent literatures can be indexed as a whole, of which 8 articles in-cluding 739 samples entered this Meta analysis. The pooled sensitivity, specificity and odds rate were 91.4% ,99.5% and 30.88 re-spectively. The area under the SROC curve was 0. 822 5. Conclusion SELDI-TOF-MS is valuable in diagnosis of ovarian cancer.

Objective To evaluate the early effect of Wallis interspinous dynamic stabilization system (Wallis system) in treatment of lumbar degenerative disease. Methods From January 2008 to Jan-uary 2009,21 patients(23 intervertebral spaces) with early lumbar disc herniation and lumbar spinal stenosis were treated with Wallis system. Four intervertebral spaces of L_(3-4) 19 intervertebral spaces of L_(4-5). Observed the time of total operation and implantation,the blood loss,and early recovery. The patients' visual analogue scale (VAS) and Oswestry disability index (ODI) scores were evaluated before and after operation. Results All patients were followed up for average (12.5 ± 0.4) months (7-18 months) after operation. The VAS and ODI scores at 7 days after operation dropped from (7.5 ± 1.5), (40.0 ± 2.0) scores before operation to (2.5 ± 0.5), (23.0 ± 1.5) scores (P < 0.01). Conclusion It is safe and easy to use Wallis system in the treatment of lumbar degenerative disease, with the advantage of mini-invasion and early effect.
