This study was aimed to compare the mechanical characteristics under different physiological load conditions with three-dimensional finite element model of rigid fixation and elastic fixation in the lumbar. We observed the stress distribution characteristics of a sample of healthy male volunteer modeling under vertical, flexion and extension torque situation. The outcomes showed that there existed 4-6 times pressure on the connecting rod of rigid fixation compared with the elastic fixations under different loads, and the stress peak and area of force on elastic fixation were much higher than that of the rigid fixations. The elastic fixation has more biomechanical advantages than rigid fixation in promoting interbody lumbar fusion after surgery.

Methods Nurses with working years within 6 years in our hospital were chosen from May, 2009 to May, 2010. And through non-professional reading, specified materials reading, multimedia lectures, particularly the refining and essence of reading reports, humanities knowledge and humanistic care consciousness was melted into personal morality, words, deeds and cultivation. Investigation about satisfaction degree was carried out among patients before and after the training. Results Satisfaction degree of patients increased after training, so did the satisfaction degree of nurses to reading reports. Conclusions To integrate nurses' humanistic quality into professional nursing training can improve humanistic quality of nurses and nursing quality. Nurses' professional image will be increasingly standard, overall quality and service quality can be improved, and thought of dedicated service for patients will be consolidated.

Aim: To construct a prokaryotic expression vector carrying NuBCP-9-tumstatin(74-98) (abbreviated as NT) gene and to obtain the fusion peptide with antitumor activity. Methods: Nucleotide sequences of antitumor peptides, NuBCP-9 and Tumstatin( 74-98), were connected via a linker(G_4S)_3 based on biased codons of E. coli the fused NT gene was reconstructed using SOE PCR, and inserted into pET32a(+) vector, and transformed in E. coli BL21(DE3). After expression, the novel fusion peptide was purified through nickel-affinity chromatogra-phy, Factor Xa digestion and ultrafiltration. Biological activity of the fusion peptide on ECV304 and A549 cells was evaluated by MTT assay. Results: A prokaryotic expression system with NT gene was successfully constructed. The soluble fusion peptide was accounted for approximately 25% when induced by 0. 5 mmol/L IPTG at 30 ℃ for 4 h. The purified fusion peptide could inhibit cell growth of ECV304 and A549 with inhibition rates of 60. 8% and 65. 2% at 20 μmol/L, respectively. Conclusion: A novel fusion peptide with antitumor activity was cloned, expressed and purified.
