简介:寻常狼疮是皮肤结核中最常见的类型,约占所有皮肤结核患者的半数。本病易侵犯儿童和青少年,好发于面部,影响容貌。我们用异烟肼、乙胺丁醇和利福平联合治愈寻常狼疮2例,报告如下。
简介:目的:采用免疫组织化学法检测HPVL1壳蛋白的表达,并进一步分析研究其与宫颈病变的严重程度的关系。方法:选取我院妇科就诊患者的宫颈脱落细胞标本529例,所有患者进行薄层液基细胞学检查,同时行宫颈活检并采用免疫组织化学法检测HPVL1壳蛋白的表达,并且分析其与不同程度宫颈病变的相关性。结果:在慢性宫颈炎、CINⅠ、CINⅡ、CINⅢ和宫颈鳞癌中,HPVL1壳蛋白的阳性表达率分别为26.16%、60.76%、30.98%、16.54%、0%,CINⅠ组与CINⅡ组、CINⅢ组和宫颈鳞癌组的HPVL1壳蛋白阳性表达率之间差异性均具有统计学意义(P均〈0.05)。在NILM、ASCUS、LSIL、HSIL、SCC中,HPVL1壳蛋白的阳性表达率分别为20.15%、35.29%、63.63%、18.39%、0%,HSIL组与LSIL组的HPVL1壳蛋白的阳性表达率之间的比较,差异有显著统计学意义(P均〈0.05)。结论:HPVL1壳蛋白的表达随宫颈病变程度的加重而降低,表明HPVL1壳蛋白表达的检测对癌前病变的筛查和预防有着重要意义。

简介:目的研制人乳头瘤病毒16型(HPV16)L1/E7CTL重组杆状病毒载体。方法以包含HPV16标准病毒株的质粒pHPV16为模板,采用PCR技术扩增HPV16主要衣壳蛋白L1(1-471aa)的基因序列,同时人工合成E7蛋白CTL表位E749-57的编码序列,将两个目的基因逐步连接构建重组质粒pUC19HPV16L1/E7CTL,HPV16L1/E7CTL片段经质粒pFastBac1转位至BacmidDNA后通过PCR鉴定重组杆粒。结果成功构建了包含融合基因HPV16L1/E7CTL片段的克隆质粒puc19HPV16L1/E7CTL,制备了L1/E7CTL重组杆状病毒载体杆粒BACMIDDNA。结论采用分子克隆技术构建了包含L1/E7CTL的重组杆粒BACMIDDNA,有利于下一步融合蛋白的表达,制备一种能够更有效激发CTL杀伤作用的嵌合病毒样颗粒疫苗,为疫苗研制打下基础。
