RESUMEN
Objective To develop an autopsy table for the cervical surgery of the small animal to enhance the efficiency by regulating the angles during the operation to expose cervical vertebra adequately.Methods The autopsy table was composed of a table body,a head rack and a foot rack.The head rack was connected with the body by a loose-leaf shaft,which had a screw under a semi-cylindrical cushion put into a sliding slot of the cushion to regulate and fix its position.The table body had four straps at its comers to imobilize the extremities of the experimental animal,and some screws were used to adjust and position the straps to four oblique sliding slots.Results The autopsy table adapted itself to sizes of small animals,which gained advantages in exposure of operating field,short operating time,decreased intraoperative blood loss,head imobilization as well as reduced workload.Conclusion The autopsy table enhances surgery efficiency and safety and has easy operation and low cost,and thus is worthy promoting in the cervical experiment of small animals.

RESUMEN
<p><b>OBJECTIVE</b>Using comprehensive available data on women breast cancer in China, to describe the mortality trends from late 1970s, estimate and project the profile in 2000 and 2005, and to aim to provide a reference for clinic, basic research and prevention and control strategy making for breast cancer in China.</p><p><b>METHODS</b>Using Joinpoint model, the mortality trends were analyzed on the basis of routine surveillance data. Combining with the data from the second national mortality survey and several cancer registries, using the log-linear model (based on Poisson distribution), the breast cancer profile in 2000 and 2005 were estimated and projected.</p><p><b>RESULTS</b>Although there was a slight decline in mortality between early 1970s and 1990s, the age-specific mortality rates among young and middle age women increased dramatically which followed a continuing increase trend on both rates and absolute numbers, in both urban and rural areas in recent 15 years. Compared with 2000, there are 470 thousands more new breast cancer cases and 130 thousands more deaths from breast cancer in 2005.</p><p><b>CONCLUSION</b>Due to the double effects of both increasing risk factors and population growth and ageing, breast cancer will be one of the most extensively increasing cancers in Chinese women. The prevention and control of breast cancer will be of great emphasis for future cancer control strategy in China.</p>
