简介：高免疫球蛋白E综合征（HIES）是一种罕见的免疫缺陷性疾病，表现为血清IgE水平升高、皮肤湿疹、反复皮肤感染和特征性的肌肉骨骼表现。作者报道2例在本院就诊的患者并回顾当前文献。患者1是一18个月大的非裔美国男孩，伴有复发性葡萄球菌冷脓肿、肺炎和菌血症。该患者皮肤严重湿疹化，最终并发疱疹性湿疹。在选用敏感抗生素环孢素A（5mg／kg）短期治疗全身性感染后，皮炎改善，随后改为长期口服甲氧苄啶一磺胺甲恶唑。患者2是一15岁高加索男孩，长期患有HIES。该患者从3岁开始即维持每周3次注射1干扰素和每月静脉注射免疫球蛋白，并预防性应用抗生素和小剂量氟康唑。

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。

简介：目的检测活化型表皮生长因子受体(EGFR)和转录调节因子E2F在尖锐湿疣中的表达。方法采用免疫荧光方法观察活化型EGFR和E2F在尖锐湿疣(CA)皮损中的表达情况。结果活化型EGFR在CA皮损角质形成细胞膜上的表达较正常对照组显著增强(P<0.01)。而且,活化型EGFR和E2F在CA皮损中的双重阳性表达较正常对照组显著增强(P<0.01)。结论活化型EGFR表达的增强导致核内转录因子的激活而参与CA的增殖病变。
