Thymopentin (TP5) and bursopentin (BP5) are both immunopotentiators. To explore whether the TP5-BP5 fusion peptide (TBP5) has adjuvant activity or not, we cloned the TBP5 gene and confirmed that the TBP5 gene in a recombinant prokaryotic expression plasmid was successfully expressed in Escherichia coli BL21. TBP5 significantly promoted the proliferation of thymic and splenic lymphocytes of mice. The potential adjuvant activity of the TBP5 was examined in mice by coinjecting TBP5 and H9N2 avian influenza virus (AIV) inactivated vaccine. HI antibody titers, HA antibodies and cytokines levels (IL-4 and IFN-γ) were determined. We found that TBP5 markedly elevated serum HI titers and HA antibody levels, induced the secretion of both IL-4 and IFN-γ cytokines. Furthermore, virus challenge experiments confirmed that TBP5 contributed to inhibition replication of the virus [H9N2 AIV (A/chicken/Jiangsu/NJ07/05)] from mouse lungs. Altogether, these findings suggest that TBP5 may be an effective adjuvant for avian vaccine and that this study provides a reference for further research on new vaccine adjuvants.

Objective To understand the changes of schistosomiasis epidemic situation,so as to provide the evidence for for?mulating schistosomiasis control strategy in the Hexi reservoir area. Methods From 2012 to 2015,Xinyuan Village,Meishan Town in the north entrance of Hexi reservoir was selected as a monitoring site. According to the requirements of the monitoring program of schistosomiasis surveillance in Zhejiang Province,the Schistosoma japonicum infection was investigated by using the serological screening(IHA),and the basic situation of the surveillance site was also investigated. Results From 2012 to 2015,167 environments(21.68 hm2)were surveyed,and 2 slices(0.1 hm2)were found with Oncomelania hupensis snails. The detection rate of frames with snails was 0.12%,and the living snail density was 0.0192 snails per 0.1 m2. Totally 374 snails were dissected and no schistosome infected snails were found. A total of 970 local residents and 8 748 mobile people were investigated with the serological tests,and no schistosome infected people were found. In addition,3 085 cattle were investigated and no in?fected ones were found. Conclusion The schistosomiasis epidemic situation is stable in the Hexi reservoir area,but we still should strengthen the monitoring of imported source of infection and snail status,and increase the efforts of environmental trans?formation.

Objective To establish an animal model to investigate the effects of prolonged vaginal distension on the leak-point pressure(LPP) and urethral anatomy.Methods Eighteen virgin female rats were randomly divided into control group(6 rats) and experimental group(12 rats).In the experimental group,the rats were underwent vaginal distension for 4 h. The rats in the control group were not received vaginal distension.The greatest bladder volume and LPP were measured,and sneeze test was performed for all rats in two groups 4 weeks after distension.All the rats were killed after the test and the bladder and urethra were harvested for histological study.Results The greatest bladder volume and LPP were significantly decreased than those of control group.Stress urinary incontinence(SUI) was occurred in 45.5% rats of the experiment group,but none in control group.Histological studies showed that the urethral striated and smooth muscle became thin,but the collagenic tissue was increased.There was no change in control group.Conclusion Prolonged vaginal distension can cause SUI and it is a desirable animal model for studying the mechanism and treatment of SUI.
