HCV抗体阳性者血清B族载脂蛋白中HCV-RNA表达及与脂质的关系

目的：探讨慢性丙型肝炎患者HCV感染与脂类代谢的关系及特点。方法：采用免疫沉淀法,以羊抗人载脂蛋白B（Apo-B）抗血清沉淀HCV抗体阳性者血清Apo-B,再以PCR技术进行扩增检测Apo-B中HCV-RNA,并设多组阴性对照。结果：实验组15例HCV抗体阳性者血清Apo-B中,14例有HCV-RNA表达,且载量较高,而对照组26例血清及其Apo-B中却没有HCV-RNA表达。结论：HCV抗体阳性者血清Apo-B中检出HCV-RNA,进一步证实了HCV感染与脂质密切相关。

丙型肝炎与自身免疫反应

丙型肝炎病毒（HCV）感染与自身免疫关系密切，这是因为一方面感染者血中存在多种自身抗体，肝外器官或组织出现自身免疫性损伤；另一方面在自身免疫性肝炎患者中检出抗-HCV。正确认识两者的关系，对某些自身免疫性疾病的病因学研究和指导治疗有重要意义。IHCV感染时的自身免在现象HCV感染时，尤其是慢性感染进程中，可在患者血中检测到各种自身抗体，提示HCV感染可诱发机体产生自身免疫。各种自身抗体中，以抗核抗体（ANA）和平滑肌抗体（SMA）检出率最高，其次抗单链DNA抗体（抗SSDNA）和1型肝肾微粒体抗体（抗一LKMI），抗…     

自身抗体检测在自身免疫性肝病诊断中的临床价值

目的：探讨自身抗体检测在自身免疫性肝病诊断中的临床价值。方法87例自身免疫性肝病分为原发性胆汁性肝硬化（PBC）组（n=45例）和自身免疫性肝炎（AIH）组（n=49例），同期选择40例乙型肝炎病毒（HBV）感染者和45例门诊健康体检者。采用免疫印迹法检测抗线粒体抗体（AMA-M2）、抗三联融合蛋白抗体（M2-3E）、抗核点型抗体（SP100）、抗早幼粒细胞白血病蛋白（PML）、抗核糖核蛋白抗体（GP-210），采用酶联免疫吸附法（ELISA）检测抗核抗体（ANA）及肝炎病毒标志物。结果 PBC组和AIH组患者自身抗体检出阳性率（93.3%、83.3%）均明显高于HBV组和对照组（7.5%、2.2%）（P<0.05）。结论自身抗体检测对自身免疫性肝病诊断具有较高的临床价值，其中AMA-M2、M2-3E等抗体诊断PBC的敏感性较高，而ANA诊断AIH的敏感性最高。     

三种方法检测乙型肝炎核心抗体的比较

应用三种方法检测了118名HBsAg阴性的正常人和269例乙型肝炎病人血清,比较了抗-HBc的检出率。证明免疫粘连血凝试验(IAHA)、微量固相放射免疫测定(SPRIA)和酶联免疫吸附试验(ELISA)检测正常人血清抗-HBc的阳性率分别是16.1％,30.5％和26.3％。急性乙型肝炎病人血清的检出率SPRIA和ELISA比IAHA高。然而,这三种方法检测慢性乙型肝炎病人血清阳性率没有明显差别。我们还发现:检出的抗-HBc几何平均滴度IAHA最低,ELISA其次,SPRIA最高。

Estimation of accumulated dose of radiation by method of ESR-spectrometry of dental enamel of mammals

ESR-spectrometry was used to investigate radiation-induced paramagnetic centers in enamel of mammals: carnivores (polar bear and fox), ungulates (reindeer, European bison, moose), and man. Values at half the microwave power saturation of the radiation signal, P_1/2, evaluated at room temperature, was found to range from 16 to 26 mW for animals and man. A new approach to discrimination of the radiation induced signal from the total ESR spectrum of reindeer enamel is proposed. ‘Dose-response’ dependencies of enamel of different species mammals were measured within the dose range from 0.48 up to 10.08 Gy. Estimations of ‘radiosensitivity’ enamel of carnivores and ungulates showed good agreement with radiosensitivity enamel of man by ESR method.     

Analysis of the results of the international comparison of activity measurements of a solution of Fe

The results of an international comparison of activity measurements of a solution of ⁵⁵Fe organized by the BIPM in 2005 are reported and analysed. This exercise, which follows the procedures of the CIPM mutual recognition arrangement to update older comparisons, is a renewal of the comparison organized by the BIPM that took place in 1978. A EUROMET comparison was organized in 1996 specifically to compare activity measurements of a ⁵⁵Fe solution by means of liquid-scintillation techniques. Results of these three comparisons are presented and discussed in this paper.

The radionuclide solution was provided by the NPL, which also distributed the samples to the participants. The activity of the ampoules was measured by 16 laboratories using 12 methods producing 25 results. Some general considerations on uncertainty assessments pertaining to the different techniques used are drawn. The outcome of four different estimators is compared from which the presence of at least one outlier can be confirmed. Further measurements should be made to try to reduce the discrepancy between the results. To date the outcome of the present comparison does not show an improvement to that of the 1996 comparison.     

Evaluation of the results of various technics of non-surgical therapy of varicocele

A new method of non-surgical treatment of varicocele syndrome is described: it consists in sclerotherapy of spermatic vein by trans-femoral percutaneous catheterization with balloon-catheters. In 8 cases venous thrombosis has been induced by direct electric clotting. The techniques and a 6 months follow-up are discussed. It is pointed out that this procedure should be considered as the method of choice for tubular lesions and sub-fertility prophylaxis in young people and in childhood.
