The PSCA_3 fragment was selected for its superior expression level in eukaryotic cells.Then the sig-PSCA_3-Fc-GPI genetic fragment was cloned into pVAX1-neo-IRES-GM/B7 vector to construct the final immunological inhanced DNA vaccine pVAX1-PSCA_3-FcGB. Immunofluorescence and flow cytometry were used to confirm the expression of PSCA_3 fragment by transfected into Cos7 cell.Finally,the anti-tumor effect of pVAX1-PSCA_3-FcGB was tested in murine prostate cancer model generated by RM-1 cell line.The animal was immunized with pVAX1-PSCA_3-FcGB DNA vaccine by intramuscular injection plus electroporation,pVAX1 and pVAX1-PSCA_1-FcGB plasmid were used as control.The inhibitory effect of tumor was investigated by observion of forming time,volume and inhibition ratio of tumor.Results:DNA sequencing conformed that the heterological PSCA fusion antigen fragment which was synchronized by overlapping-extending-PCR,was consistent to design.Enzyme digestion analysis showed that the 1 to 4 copies heterological PSCA fusion antigen fragments were constructed successfully.

There is still high incidence of hepatitis A in the developping country. The wide-spread use of HAV live attenuated vaccine and inactive vaccine has provided efficient ways for controlling the epidemic of heptatitis A. while, some people got hepatitis A after injecting vaccines. In order to distinguish the viral capsid could result from hepatitis A vaccines or from natural infection, the identification of the virus strains is necessary. In 1975, KO|¨hler and Milstein have developped hybridoma technique for producting monoclonal antibody.

甲型肝炎在发展中国家多年来都有不同程度的流行，甲肝减毒活疫苗和灭活疫苗的使用，为甲肝的预防提供了可靠的手段，但偶有在接种疫苗后发生甲型肝炎的案例，这就需要对患者所感染的病原体进行鉴别，以明确患者发病的原因是接种疫苗引发还是甲肝野毒株感染导致的偶合病例。1975年KOhler和Milstein建立了杂交瘤技术制备了单克隆抗体(monoclonal antibody；McAb)。

Restrictive changes of TCR Vp repertoire and clonal expanded T cells could be found in peripheral blood T cells from patients with T-ALL. However, the clonal expanded T cells' property (clonal expansion leukemic cells or leukemia antigen-specific expansion T cells) should be further characterized. It may play a certain role on detection of minimal residual disease and design of anti-leukemia idiotypic vaccine. The dominant utilization of TCR VjJ repertoire could be found in peripheral blood T cells from patients with B-ALL, meanwhile clonal expansive T cells were existed. It may be a feature of the host immune response for leukemia-associated antigen. The clonal expansive tendency of T cells in V021 and VP23 subfamilies was rather obvious, which may be correlated with certain malignant B-cell clone. The CDR3 sequences of monoclonal expansive T cell in T cell strains were different, which was the base of developing DNA vaccine.

T-ALL患者外周血T细胞的TCR Vβ谱系出现限制性改变，均可检测到克隆性增殖T细胞，尚需进一步鉴定其性质(肿瘤性或抗原特异性增殖)，对于研究微小残留病变检测和设计抗白血病独特型疫苗均有一定的意义。B-ALL病人外周血T细胞的TCR Vβ谱系呈现优势利用的特点，并存在克隆性增殖的T细胞，这可能是机体对白血病相关抗原产生的特异性免疫反应；Vβ21和Vβ23亚家族T细胞发生克隆增殖改变的趋向性比较明显，可能与B-ALL相关抗原刺激有关。T细胞株中检测到的肿瘤克隆其CDR3序列具有高度的特异性，是构建DNA疫苗的基础。
