RESUMO
OBJECTIVE@#To predict structure and function of translationally controlled tumor protein (TCTP) from Spirometra mansoni by bioinformatics technology, and to provide a theoretical basis for further study.@*METHODS@#Open reading frame (ORF) of EST sequence from Spirometra mansoni was obtained by ORF finder and was translated into amino acid residue by DNAclub. The structure domain was analyzed by Blast. By the method of online analysis tools: Protparam, InterProScan, protscale, SignalP-3.0, PSORT II, BepiPred, TMHMM, VectorNTI Suite 9 packages and Phyre2, the structure and function of the protein were predicted and analyzed.@*RESULTS@#The results showed that the EST sequence was Sm TCTP with 173 amino acid residues, theoretical molecular weight was 19 872.0 Da. The protein has the closest evolutionary status with Clonorchis sinensis, Schistosoma mansoni, and Schistosoma japonicum. Then it had no signal peptide site and transmembrane domain. Secondary structure of TCTP contained two α -helices and eight β -strands.@*CONCLUSIONS@#Sm TCTP was a variety of biological functions of protein that may be used as a vaccine candidate molecule and drug target.

Objective To observe morphological character of posterior arch of Atlas and lamina of axis,as well as provide anatomical basis to design special guiding device for the operation of upper cervical posterior fixation with Atlas titanium cable so as to make the operation safe and easy.Methods The posterior arch of Atlas and lami- na of axis were observed and measured in 100 adult dry Atlas and axis specimens,then special guiding devices were designed based on the anatomical data.Results (1)The posterior arch of Atlas was thin with a fan-shape section, whose inner plane descended from back to inside and the lamina of axis was stronger and thicker than posterior arch of Atlas,with a vertical inner plane and a ridge near the lower edge.(2)The special guiding device for posterior arch of Atlas should be designed with a bend head as well that for lamina of axis should be designed with a round head. They were used in 61 operations which became safer and easier.Conclusion The operation of upper cervical posteri- or fixation with Atlas titanium cable would be safer with the help of special guiding devices which were designed based on the anatomical character.
