Materials and 64 dust acarid allergic rhinitis outpatients were randomly divided into 2 groups, 31 patients in the control group were treated with general immunotherapy, 33 patients in the trial group were treated with NHD, the serum level of IL-4, IL-5 was detected by ELISA.

常年性变应性鼻炎患者64例，随机分为常规免疫治疗组31例，标准化尘满变应原疫苗治疗组33例，比较两组患者在接受免疫治疗后的疗效及血清IL-4、IL-5水平。

NHD specific immunotherapy could attenuate the production of cytokine IL-4, IL-5 and is effective for treatment in dust acarid allergic rhinitis.

尘螨标准化变应原疫苗免疫治疗是一种有效、安全的治疗常年性变应性鼻炎的方法，可能通过减少机体IL-4、IL-5的生成，从而减轻IL-4、IL-5对常年性变应性鼻炎患者的免疫毒害作用，发挥其调节免疫的作用，进而达到有效治疗常年性变应性鼻炎的作用。

The homology of the nucleotide sequences and genetic variation analysis of NDV strains suggested that mere were obvious divergence in gene lever among NDV vaccine strains and epizootic strains isolated from different areas and different ages.The divergence may have effect on amino acid and structure and function of protein in some extent and lead to difference of immunogenicity ,which was one of reason being difficult in preventing from ND.

通过对NDV F基因核苷酸序列同源性比较及遗传变异分析发现：我国不同年代、不同地区分离的NDV毒株与疫苗毒株之间在基因水平上存在较大差异，这种差异对氨基酸及蛋白质的结构和功能可能会有一定影响，而NDVF蛋白的差异同时也造成免疫原性的差异，这很可能是新城疫的免疫防治十分困难的原因之一。

In this study, a recombinant plasmid generating short hairpin RNA was constructed — To construct the recombinant plasmid carrying shRNA to HPV6bL1 and analyze the nucleicacid sequence for further searching new gene therapy method of cauliflower excrescence.

目前对于尖锐湿疣仍无有效的病毒特异性防治措施来保护人类免受其危害，而基因疫苗则为预防HPV感染提供了可能性；L1是HPV6型主要的衣壳蛋白，具有较强的免疫原性，可刺激机体产生保护性的中和抗体。

Objective To observe the immunogenicity of combined hepatitis A and B vaccine.
