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.

This paper reviews the clinical researches on acupuncture and moxibustion treating female overactivity of bladder (OAB), and finds that acupuncture and moxibustion treating female OAB hastheraputic effect with simplicity, little adverse reaction and could take effect in a short period of time. Electroacupuncture has combined the effects of acupuncture and nerve electrical stimulation treatment, and it takes few acupoints and is easy to operate. The main acupoints of one or more points of Baliao acupoints shows obvious clinical effect, and navel moxibustion method and auriculo-acupuncture can improve the frequency and urgency of urination of OAB. The combination of using acupuncture and moxibustionhas certaineffect, however, due to the complicated procedures and long treatment courses, it’s not used widely in cinic.
