Preliminary Studies of in situ Hybridization in Routine Paraffin Embedded Liver Tissue Sections with iotinylated HBV DNA Probe:Localization and Morphology of HBV DNA in Various Types of Liver Diseases

The in situ hybridization of HBV DNA with biotinylated probe informalin-fixed and paraffin-embedded liver tissue sections was performed and thelocalization and morphology of HBV DNA in various types of chronic liver diseases wereobserved.25 out of the 75 cases studied were HBV DNA positive (33.3%).HBV DNA inhepatocytes was demonstrated as numerous coarse grains in cytoplasm and occasionally afew grains in individual nuclei.The distribution of the HBV DNA positive hepatocytes inthe sections was in 3 types,i.e.,the diffuse type (Type I,4/25,16%),the focal type (Type Ⅱ,20/25,80%),and the scattered type (Type Ⅲ,1/25,4%).The HBV DNA grains incytoplasm might be condensed (Type a) or sparsed (Type b) depending on the number of theHBV DNA grains.The different distribution patterns and the amount of HBV DNAgrains might be a reflection of the replication activity and the state of infectivity of HBV.HBV DNA positive hepatocytes were found only in the tissues contiguous to the cancertissue in cases with hepatocellular carcinoma with cirrhosis.

HBV核心启动子A1762T/G1764A双突变与慢加急性肝衰竭关系的研究

Objective To analysis the relationship between HBV BCP A1762T/G1764A double mutation with acute on chronic liver failure(ACLF).Methods HBV BCP A1762T/G1764A double mutation was detected in 166 HBV chronic infection patients by nested PCR and direct DNA sequencing.The mutation rate was compared among the patients with different disease course.Results Among 166 patients,45 patients,45 patients,49 patients and 27 patients were diagnosed as chronic hepatitis B(CHB),liver cirrhosis(LC),ACLF and hepatocellular carcinoma(HCC),respectively.A1762T/G1764A double mutation rate was 40.0%(18/45),84.4%(38/45),73.5%(36/49)and 92.6%(25/27) respectively in different groups.However,A1762T/G1764A double mutation rate has no difference between ACLF based on CHB and LC(P=0.502)and between patients with HBeAg positive and negative(P=0.735).HBV DNA level (log) of patients with A1762T/G1764A double mutation was 5.68±1.36,lower than but having no significant statistic difference compared to patients without the double mutation(6.14±1.81,P=0.075).Conclusion A1762T/G1764A double mutation has a close relationship with the progress of HBV-infection diseases,but is not specific to patients with ACLF.And patients with BCP double mutation have similar HBV DNA levels and HBeAg status with patients without the double mutation.

目的分析先天性肝纤维化的临床特征。方法对12例先天性肝纤维化患者临床表现、实验室检查及病理组织学特点进行回顾性分析。结果12例患者均有明显临床症状,10例有典型门脉高压症状,11例就诊时肝功能异常,肝脏病理主要表现为：肝组织内呈现宽大致密且炎症不明显的胶原纤维间隔,或纤维束弥漫穿插于固有的肝小叶内,无典型的假小叶结构。结论对于不明原因肝功能异常的门脉高压症患者,应尽可能进行肝组织活检病理检查以协助诊断及指导治疗。     

双环醇片治疗慢性乙型病毒性肝炎的评价

目的评价双环醇片治疗成人慢性病毒性乙型肝炎的疗效与安全性。方法计算机检索中国生物医学文摘数据库，中国期刊全文数据库，和中文科技期刊数据库及PubMed等数据库，纳入比较双环醇片与非特异性治疗、干扰素、拉米夫定治疗慢性乙型病毒性肝炎患者的随机临床试验。纳入试验的质量由两名评价员独立评价。试验数据的统计分析采用Cochrane协作网提供的RevMan4．2软件进行。结果最终纳入14个临床试验1782例患者。ALT复常率双环醇组（69．3％）高于对照组（59．0％），（P=0．04），HBeAg阴转率双环醇组（22．1％）高于对照组（13．5％），（P〈0．00001）。没有严重不良事件报道。结论双环醇促进慢性病毒性乙型肝炎患者的肝功能恢复，对血清病毒标志物清除可能有一定效果。
