人乳头瘤病毒11型L1/E7嵌合DNA疫苗的构建及其诱导的免疫效应

目的 构建人乳头瘤病毒11型L1/E7嵌合DNA疫苗pcDNA3 L1-E7并研究其在小鼠中诱导的免疫效应.方法 用分子克隆技术构建重组真核表达质粒peDNA3 L1-E7.重组质粒DNA股四头肌注射免疫小鼠,用ELISA方法 检测L1、E7特异性抗体和脾细胞分泌的IL-2、γ-INF;MTT法检测脾淋巴细胞增殖反应.结果 成功构建pcDNA3 L1-E7.免疫小鼠后,重组质粒可诱导机体产生特异性脾淋巴细胞增殖及IL-2、γ-INF分泌增加,并诱导机体产生HPV 11-E7 IgG和HPV 11-L1 IgG抗体.结论 嵌合DNA疫苗pcDNA3 L1-E7能诱导小鼠产生特异性的细胞免疫和体液免疫反应.     

人乳头瘤病毒11型L1/E7嵌合DNA疫苗的构建及其诱导的免疫效应

Objective To construct chimerical DNA vaccine plasmid of human papiUomavirus type 11 (HPV11) L1-E7, and to evaluate its immunogenicity. Methods Molecular cloning techniques were used to construct recombinant plasmid PeDNA3 L1-E7 as a DNA vaccine. BALB/c mice were vaccinated with DNA recombinants through muscle injection. IL-2 and γ-INF secreted by immunized spleens lymphocyte and HPV 11 LI or E7 specific antibodies were assayed by ELISA method. Spleens lymphocyte proliferation was measured by MTT assay. Results The chimerical DNA plasmid of pcDNA3 LI-E7 was constructed correctly. Specific anti-HPV11 E7 and L1 antibodies, specific lymphocyte proliferation and secretions of IL-2 and γ-INF were detected in vaccinated mice. Conclusion Specific immune response, including cellular immunity and humoral immunity, could been detected in mice vaccinated with chimerical DNA vaccine of pcDNA3 L1-E7.

DNA甲基化在肿瘤无创性分子诊断中的研究进展

DNA甲基化是真核细胞基因组最常见的一种表观遗传学修饰.DNA甲基化异常在肿瘤的发生、发展过程中扮演重要角色.研究显示DNA甲基化是一类潜力很大的肿瘤标志物.肿瘤特异性的DNA甲基化标志物可从肿瘤患者血清/血浆、尿液、粪便和支气管肺泡灌洗液中检出,为进行肿瘤无创性诊断DNA甲基化检测提供了新思路.本文对DNA甲基化在恶性肿瘤早期诊断的研究进展作一综述.     

小切口白内障囊外摘除联合人工晶体植入术的护理配合体会

白内障囊外摘除术(ECCE)是将晶状体核和皮质摘出而保留后囊膜的术式,目前是我国的白内障主导术式[1]。其联合后房型人工晶体植入术(以下简称ECCE IOL术),术后可迅速恢复视力,建立双眼单视和立体视[2]。现就78例78眼小切口ECCE IOL术的护理配合体会报告如下。临床资料本组共78例78眼,均为2003年2月至2006年2月在广西区人民医院眼科住院的老年性白内障患者,男36眼,女42眼。年龄48~88岁,平均61.3岁。患者平均住院时间为6±1天。术后全部达到复明目的。护理措施1.术前准备①全面检查和术眼准备:系统专科检查,计算所需IOL的度数;全身行…     

8q24 rs13281615基因多态性与中国汉族女性乳腺癌患病风险及临床病理特征的关系

乳腺癌发病是多因素共同作用的结果.与家族性乳腺癌相比,大多数散发性乳腺癌的发生主要与低外显率基因的多态性有关.最近,Easton等[1]和Hunter等[2]的2项大规模的全基因组关联研究(GWAS)发现了几个新的乳腺癌易感基因位点.
