慢性乙型肝炎患者HBeAg、ALT与HBV-DNA相关性探讨

检测555例HBeAg阳性慢性乙型肝炎患者血清HBeAg定量、HBV—DNA及丙氨酸氨基转移酶（ALT）水平，并进行相关性分析。结果发现本组患者HBeAg定量与HBV．DNA定量呈正相关（r为0．457，P〈0．05），血清ALT水平与HBeAg定量和HBV—DNA定量呈负相关（r分别为-0．152、-0．194，P均〈0．05）。认为血清HBeAg、ALT及HBV—DNA三者相互影响，在慢性乙型肝炎诊断中均有重要意义。     

乙型肝炎病毒E抗原、大蛋白与乙肝病毒DNA的关系

目的：探讨乙型肝炎病毒（HBV）表面E抗原（HBeAg）、大蛋白（LHBs）与乙肝病毒DNA（HBV DNA）的关系。方法分别检测109例HBeAg阳性和116例HBeAg阴性的乙型肝炎患者的LHBs、HBV DNA表达情况,并进行对比分析。结果 HBeAg阳性组中,LHBs、HBV DNA的检测率分别为89．9％和84．4％,二者比较无统计学差异（P＞0．05）;HBV DNA定量与HBeAg定量和LHBs均呈正相关（r分别为0．81、0．94,P均＜0．05）,不同HBV DNA载量组间HBeAg定量和LHBs含量均有统计学差异（P均＜0．01）。结论对HBeAg阴性患者而言,LHBs能在一定程度上反映体内HBV的复制情况,可作为HBV DNA的补充,指导临床诊治和用药。     

HBeAg、HBV DNA联合定量检测对HBeAg阳性不同程度慢性乙型肝炎的临床意义

目的：探讨 HBeAg与 HBV DNA 联合定量检测对 HBeAg 阳性的不同程度慢性乙型肝炎的临床意义。方法选择47例慢性乙型肝炎、12例乙型肝炎肝硬化和7例肝细胞癌患者）,χ2检验、t检验及秩和检验分析比较两组患者的年龄、性别、肝功能、HBeAg、HBV DNA 等指标。采用 ROC 曲线评价 lgHBV DNA、lgHBeAg、lgHBV DNA/lgHBeAg诊断乙型肝炎肝硬化、肝癌的准确性。结果慢性乙型肝炎组 HBeAg 定量高水平组与低水平组,在性别、年龄、HBV DNA、TBil、ALT、Alb、PT,差异无统计学意义（P〉0.05）。HBV DNA 定量高水平组与低水平组在性别、年龄、HBeAg、TBil、ALT、Alb、PT,差异无统计学意义（P〉0.05）。慢性乙型肝炎组的 HBeAg、HBV DNA 水平高于乙肝肝硬化及肝癌组（P〈0.05）。lgHBV DNA/lgHBeAg诊断乙肝肝硬化肝癌的准确性比其中单一种准确性高,最佳截断值12.31,灵敏度0.412,特异度0.867。结论单一 HBeAg作为判断 HBV复制的活跃及预测疾病进展有一定局限性,故在临床联合检测 HBV DNA和 HBeAg定量,对 HBeAg阳性不同程度的慢性乙型肝炎有更好的临床指导意义。     

慢性乙型肝炎患者血清HBeAg、HBV DNA与肝组织炎症关系的探讨

目的探讨慢性乙型肝炎血清HBeAg及HBV DNA水平和肝组织炎症损害的关系.方法采用微粒子免疫捕捉分析法和荧光定量聚合酶链反应分别对74例HBeAg阴性和73例HBeAg阳性慢性乙型肝炎患者进行血清HBeAg、HBV DNA定量检测和肝组织活检病理炎症分级,对比分析结果.结果74例HBeAg阴性慢性乙型肝炎患者中27例（36%）血清HBV DNA＞105拷贝/ml,随着G1～G4肝组织炎症损害级别的增高其所占例数也相应增高,统计学分析HBV DNA水平与肝组织炎症病理分级的相关性有显著意义;血清HBeAg定量0～29 PEIU/ml,随肝组织炎症病理分级上升定量阳性（＞0.28 PEIU/ml）的病例比率增加,经统计学分析两者具有相关性.73例HBeAg阳性慢性乙型肝炎患者中有49例（67%）血清HBV DNA＞105拷贝/ml,血清HBeAg及HBV DNA水平与肝组织炎症分级无相关性.结论血清HBV DNA水平可作为判断HBeAg阴性慢性乙型肝炎患者肝组织炎症损害程度的指标,血清HBV DNA水平愈高肝组织炎症损害往往愈重.36%的HBeAg阴性慢性乙型肝炎患者血清HBeAg水平低下而HBV DNA复制活跃,可能存在HBV的前C区终止突变合并C区突变.血清HBV DNA水平不能反映HBeAg阳性慢性乙型肝炎肝组织炎症损害的程度.     

慢性乙型肝炎患者外周血HBsAg与HBV DNA相关性分析

目的探讨HBeAg（＋）和HBeAg（-）慢性乙型肝炎患者外周血HBsAg与HBV DNA的关系。方法定量检测HBeAg（＋）55例和HBeAg（-）36例慢性乙型肝炎患者血清HbsAg和HBV DNA的水平。结果 HBeAg（＋）患者血清HBV DNA、ALT和AST水平较HBeAg（-）患者高（P〈0.05）;HBeAg（＋）患者血清HBsAg水平较HBeAg（-）患者低（P〈0.05）;高水平血清HbsAg患者血清HBV DNA水平低（F=10.096,P〈0.01）;HBeAg（＋）慢性乙型肝炎患者HBsAg与HBV DNA存在负相关（r=-0.796,P〈0.01）,而HBeAg（-）慢性乙型肝炎患者HBsAg与HBV DNA无相关性（r=0.289,P〉0.05）。结论定量检测慢性乙型肝炎患者血清HBsAg水平有一定的临床意义。     

HBV感染者血清中HBVcccDNA、HBeAg及HBV DNA的关系

探讨HBV感染者血清HBVcccDNA与血清HBV DNA及HBeAg的关系。分别以PER分子信标技术和ELISA方法对非HBV相关肝炎、HBV健康携带者、急性乙型肝炎（AHB）、慢性乙型肝炎（CHB）、乙肝肝硬化、乙肝患者血清中HBVcccDNA HBV DNA含量及HBeAg进行了检测。HBVcccDNA仅见于HBV DNA阳性血清中；HBeAg阳性组的HBVcccDNA阳性率显著高于HBeAg阴性组（P〈0．05）；145例HBV DNA阳性患者中，HBVcccDNA阳性组HBVD—NA水平显著高于HBVcccDNA阴性组（P〈0．01）。血清HBVcccDNA可能是乙肝病毒在患者体内大量复制的血清标志。     

乙型肝炎患者血清HBV标志物与HBV DNA相关性分析

目的探讨乙型肝炎患者血清学标志(HBVM)与HBV DNA的关系。方法对257例乙型肝炎患者同时检测HBVM与HBV DNA。HBVM检测用EHSA法，HBV DNA检测用PCR法。根据不同检测结果进行对比分析。结果在HBsAg HBeAg HBcAb阳性的血清中HBV DNA阳性率和含量最高，血清HBeAg与HBV DNA含量密切相关，但部分HBeAg阴性或抗-HBe阳性患者也有较高的HBV DNA阳性率及含量。结论PCR定量检测HBV DNA含量更有助于判断体内HBV复制的情况及传染性强弱，在临床上有重要意义。

State of knowledge of helminth fauna of freshwater fishes of Poland

A total 89 fish and lamprey species has been recorded from Polish freshwater habitats. Twenty-seven of them (30.3%) have not been surveyed for parasitic helminthes. Some of the latter fishes are either rare or not easily accessible. Other live only in specific habitats in scattered localities. An important obstacle for studying parasite faunas of some fishes may be their status on an endangered species. Among the non-surveyed fishes, are those which have been relatively recently introduced to Poland or migrated there on their own. The present paper attempts to review all hitherto not studied helminthologically fish species, their habitats, localities and current protection status.     

Inhibition of intimal thickening of the carotid artery of rabbits and of outgrowth of explants of aorta by probucol.

The effect of administration of probucol in preventing intimal thickening of rabbit carotid artery after balloon catheter injury and the mechanism of action of the drug were studied. Groups of 6 male New Zealand-White rabbits were given normal diet (Group I), high cholesterol diet (Group II) or high cholesterol diet plus probucol (Group III) for 4 weeks. Balloon catheter injury was made in week 2 and animals were killed in week 4. No significant differences in the total cholesterol levels in Groups II and III were found in week 4. The medians of areas of the intimal layer in cross-sections of the carotid arteries of Groups I, II and III were 0.237, 0.475 and 0.309 mm2, respectively. Thus high-cholesterol diet increased the thickness of the intimal layer and probucol reduced its effect. There were no significant differences in the areas of the medial layers in these 3 groups. For the examination of the mechanism of the effect of probucol, rabbits were given chow containing 0.5% cholesterol with and without 0.5% probucol (7 rabbits each) and then the numbers of explants from their aortas showing outgrowth were compared. The plasma total cholesterol levels of these two groups were the same. The probucol concentrations in the plasma and aorta of the former group were 18.6 +/- 13.2 micrograms/ml and 7.3 +/- 5.4 micrograms/g wet tissue, respectively. The number of explants showing outgrowth on day 14 was suppressed by 34% in the probucol-treated group.(ABSTRACT TRUNCATED AT 250 WORDS)
