The slow and constant HBV infection has distinct connection with the identification, responsion and endurance of HBV antigen by human immune systems.

HBV感染的慢性化和持续感染与免疫系统对HBV抗原的识别、应答和耐受明显相关，因此HBV特异性免疫应答对决定慢性乙肝病毒感染者的病程、病理和转归有极重要的意义，是什么因素导致了机体免疫系统一系列的免疫异常进而导致对HBV感染的持续无应答状态和疾病的慢性化过程？

Results Serum anti-HBs did not reach 10 IU/L only in one of 40 non-responder children, who received intradermal revaccination.

在第5年，评价HBsAg特异性淋巴细胞免疫水平；对抗-HBs阴转者加强1针（5μg），12—14d评价抗体回忆应答。

By regularly testing for HBV serological markers, assessing HBsAg-specific T lymphocyte response in vitro by the end of follow-up, and giving a booster dose and estimating anti-HBs anamnestic response thereafter, the study, for the first time, gave a comprehensive evaluation for five-year efficacy of a three-dose revaccination in non-responders based on persistence of anti-HBs, preservation of immunologic memory, and prevention from HBV infection, and in additon compared low-dose ID revaccination with routine-dose IM revaccination.

本项目以健康学龄儿童为研究对象，严格筛检无应答者，用应答者作为同期观察对照，通过定期随访检测抗-HBs、HBsAg和抗-HBc，随访结束时检测HBsAg特异性T细胞免疫以及加强一针后检测抗-HBs回忆应答，从抗体持续时间、免疫记忆维持和预防HBV感染等几个方面首次系统评价了无应答者3针复种后5年效果，并比较了相同针次常规剂量肌肉复种与小剂量皮内复种效果。

Arthritis Rheum 1986;29:1039-1049, with permission of the American College of Rheumatology.

b临床应用中常用的是六条中符合四条，它的敏感性是84%，特异性是89%。

Objective To improve the diagnosis and treatment of rheumatic fever and probe for specific and sensitive methods for detecting the activity of rheumatic fever.

目的 为寻找新的特异性和敏感性的指标，以探讨风湿热的活动性，从而提高风湿热和风心病的诊疗水平。

RTPCR was used to investigate the expressional characteristic of RACK1（receptors for activated Ckinase） including tissue specificity and rhythmicity. The signal relation between RACK1 and Per1 was studied by RNAinterference. Result Per1 interplayed with RACK1 in the human SCN region of the hypothalamus.

采用酵母双杂交方法，以人Per1的PAS结构域为诱饵，扫描人下丘脑cDNA文库，并通过体外转录、免疫共沉淀验证蛋白间相互作用；通过RTPCR检测RACK1（receptors for activated Ckinase）表达的组织特异性及节律性；运用RNAi技术初步研究RACK1与Per1的信号联系。

These results indicate that the expressed P5 protein is an attractive source of antigen for development of an ELISA for the detection of antibodies to R. rickettsii or other agents of genus rickettsia.

以IFA结果为金标准，在立氏立克次体阳性和阴性鼠血清的检测中，以P5为包被抗原的ELISA方法的敏感性与特异性分别为100％和93.4％，表明重组P5蛋白是一个很有希望的立克次体感染的血清学诊断抗原。

Rickettsii. The purified 120kDa protein and P5 protein were recognized by sera from animals infected with agents of the genus rickettsia, not Coxiella burnetii and Orientia tsutsugamushi., suggesting the two antigens are specific for genus rickettsia.

120kDa蛋白和P5蛋白可与立克次体属的多种立克次体免疫血清发生交叉反应，与贝氏柯克斯体、恙虫病东方体不反应，提示这两种蛋白具有立克次体属特异性。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
