摘要：免疫荧光法测定病人血清中的抗核抗体(ANA)同Frious等人于1957年道德报道,临床上用于对各类核成分抗体的检测,是诊断多种自身免疫性疾病,尤其是诊断系统性红斑狼疮(SLE)的重要指标.但对用该指标诊断SLE宣的分析尚未见报道.本文旨在按诊断性试验的研究设计对用ANA诊断SEL的价值进行定量评价与分析.资料与方法1.临床资料 (1)金标准:以1982年美国风湿病学会修订的SLE诊断标准作为金标准. (2)病例级:根据金标准诊断SLE患者35例.

摘要：目的对HPV18型DNA疫苗的免疫原性和安全性进行初步评价。方法将HPV18L1基因与真核表达载体pcDNA3.1(+)连接,构建DNA疫苗质粒pcDNAL1。使用脂质体将重组质粒转染COS7细胞,用Westernblot检测体外瞬时表达的抗原。将重组质粒pcDNAL1肌肉注射BALBc小鼠(100μg只),加强免疫3次后分别采集血清,用ELISA法和Westernblot法检测抗体,实时荧光定量PCR法检测质粒的组织分布。采用ELISA法检测DNA疫苗免疫后抗核抗体和抗双链DNA抗体的效价。结果重组质粒可在真核细胞中有效地转录和表达HPV18L1蛋白。小鼠免疫后可检出较高滴度的抗HPV18L1抗体和特异条带。免疫后质粒主要分布在注射部位,且随着时间延长被清除;未检测到抗核抗体和抗双链DNA抗体。结论HPV18L1重组质粒可诱导小鼠产生特异的体液免疫反应,且该DNA疫苗是安全的,为进一步研制开发HPVDNA疫苗打下了基础。

摘要：Objective: To describe the clinical and laboratory manifestations of childhood -onset systemic lupus erythematosus (SLE) at presentation. Study design: This r etrospective French multicenter study involved 155 patients in whom SLE develope d before the age of 16 years. Mean patient age at onset was 11.5 ±2.5 years (ra nge, 1.5-16 years). The female to male ratio was 4.5. Results: The most common initial manifestations were hematologic (72%), cutaneous (70%), musculoskeleta l (64%), renal (50%), and fever (58%). Thirty-two percent of children had at ypical symptoms, mainly including abdominal involvement in 26 patients, which le ad to negative laparotomy results for presumed appendicitis. Severe renal, neuro logic, hematologic, abdominal, cardiac, pulmonary, thrombotic, and/or cutaneous manifestations occurred within the first month after the diagnosis in 40%of pat ients. The mean erythrocyte sedimentation rate was 72 ±29 mm/h, and the mean C -reactive protein value 22 ±21 mg/L. Antinuclear antibodies an, anti-double s tranded DNA antibodies, and low C3 or C4 level were retrieved in 97%, 93%, and 78 %of patients, respectively. Conclusion: Initial manifestations of childhood -onset SLE are diverse and often severe. The diagnosis of SLE should be promptl y considered in any febrile adolescent with unexplained organ involvement, espec ially when associated with an increased erythrocyte sedimentation rate.
