ABO血型与PHC患者HBV感染标记相关性研究

研究伴ＨＢＶ感染的ＰＨＣ４４５例乙型肝炎抗原抗体与ＡＢＯ血型的关系，结果表明：１．伴ＨＢＶ感染的ＰＨＣＡ型血者显著高于对照组（Ｐ＜０．０１）。２．ＰＨＣ患者中ＨＢｓＡｇ、抗－ＨＢｃ的阳性率均以Ａ型血显著高于对照组（Ｐ＜０．０５）。３．ＰＨＣ患者中ＨＢｓＡｇ与抗－ＨＢｃ均阳性模式Ａ型血者显著多于对照组，而Ｂ型血者显著少（Ｐ＜０．０５）；抗－ＨＢｅ与抗ＨＢｃ均阳性的ＰＨＣ中，亦为Ａ型血者显著多（Ｐ＜０．０５）。提示有ＨＢＶ感染的Ａ型血者罹患ＰＨＣ的倾向性最高；而有ＨＢＶＭ、ＨＢｓＡｇ、抗－ＨＢｃ的Ａ型血者则为ＰＨＣ的易感人群，其中以ＨＢｓＡｇ和抗－ＨＢｃ同时阳性或抗－ＨＢｅ和抗－ＨＢｃ同时阳性的感染模式更易发生ＰＨＣ；也提示ＰＨＣ、ＨＢＶ、Ａ型血三者之间存在某种密切的、复杂的联系，对ＰＨＣ的发生有协同作用。对上述人群应密切关注，定期复查，以期早诊早治。     

HBV 感染、家族肝癌史与 ABO 血型在低发区原发性肝癌的关系

本文研究了高、低发区５１０例ＰＨＣＨＢＶ感染、家族肝癌史及与ＡＢＯ血型的关系，结果表明：１肝癌低发区与高发区一样，合并ＨＢＶ感染的ＰＨＣ患者达８０．７４％，远多于无ＨＢＶ感染者；男性多于女性；有家族肝癌史的ＰＨＣ患者占４０．００％，且合并ＨＢＶ感染的ＰＨＣ有家族肝癌史者显著多于ＨＢＶ阴性组（Ｐ＜０．０５）；２低发区ＰＨＣ中，有家族肝癌史的Ａ型血者显著多于相应对照组（Ｐ＜０．０５）。提示我国肝癌低发区ＰＨＣ发生的最重要外因亦为ＨＢＶ感染，遗传易感性则是其内因；而有ＨＢＶ感染或有家族肝癌史者是ＰＨＣ的高危人群，且后者中的Ａ型血者更为易患，对这一人群需加强监测，警惕ＰＨＣ的发生。     

HBV,HCV在原发性肝癌发生中的相互作用研究

为了解河南省原发性肝癌（ＰＨＣ）发生中ＨＢＶ、ＨＣＶ的相互作用，我们应用ＥＬＩＳＡ法和ＰＣＲ法对ＰＨＣ患者及其１：１对照进行了ＨＢＶ标志物（ＨＢＶＭ）和ＨＣＶ标志物（ＨＣＶＭ）检测。结果：ＰＨＣ患者ＨＢＶＭ阳性率为８１．２５％，对照组ＨＢＶＭ阳性率为９．６０％，Ｐ〈０．０１，ＯＲ＝７０（２５．３６，１９３．２３）；ＰＨＣ患者ＨＣＶＭ阳性率为１９．７９％，对照组ＨＣＶＭ阳性率为８．３３％，Ｐ〈０．０     

肝癌患者同胞罹患原发性肝癌的因素及特征

本文对１５２例具有同胞患肝癌家族史的原发性肝癌先证者进行分析，结果表明：该组人群ＨＢＶ感染率为８１．５８％，感染标记类型有１２种，其中６８％为抗一ＨＢｃ阳性伴ＨＢｓＡｇ和（或）抗－ＨＢｅ阳性；发病高峰年龄为３０～４９岁（占７２％）；兄弟同患肝癌（６７．１１％）显著多于兄妹、姐弟同患，更显著多于姐妹同患（Ｐ＜０．００１），但伴有母患肝癌家族史的患者女性同胞也易患肝癌（Ｐ＜０．０２５）。提示具有同胞患肝癌史、年龄３０～４９岁、尤其是抗－ＨＢｃ阳性伴ＨＢｓＡｇ和（或）抗－ＨＢｅ阳性的男性乙肝患者为肝癌患者一级亲属中原发性肝癌最易感人群，应密切关注，警惕肝癌发生。

原发性肝癌与乙型肝炎病毒感染血清学标记的关系

为了探讨原发性肝癌（ＰＨＣ）患者血清乙型肝炎病毒（ＨＢＶ）感染标志在各年龄组间的差异，采用酶联免疫法（ＥＬＩＳＡ）检测了２２１例住院病人的血清ＨＢＶ五项标志，结果发现ＨＢＶ感染率在各年龄组均呈高值，证实了ＨＢＶ感染是ＰＨＣ的一个重要致病因素，尤其是ｅ抗原系统，ＰＨＣ患者ＨＢｅＡｇ阳性率其年龄分布，３０岁以后随年龄增长而下降，６０岁以后明显下降，差异均有显著性（Ｐ〈０．０５），３０岁～４０岁组年龄组     

肝癌患者一级亲属HBV感染的调查分析

本文从ＨＢＶ感染的角度研究肝癌家族内的遗传效应。提示ＰＨＣ患者一级亲属确是一组ＨＢＶ易感人群，且肝癌家族内ＨＢＶ感染、ＰＨＣ都呈明显的、以母系亲代传递为特征的家族聚集现象；ＨＢＶ经垂直感染可导致家族性ＰＨＣ，ＰＨＣ患者同胞是ＨＢＶ、ＰＨＣ最易感人群。因此，对该人群需密切关注，定期复查，警惕ＰＨＣ的发生。     

原发性肝癌组织中Fas和FasL的表达研究

Evidence for clustering of hepatitis B virus infection in families of patients with primary hepatocellular carcinoma.

Family member of 13 patients with hepatitis B surface antigen (HBsAg) positive primary hepatocellular carcinoma (PHC) were tested for the presence of hepatitis B virus-associated antigens and antibodies. Of the 122 members examined, circulating HGsAg was detected in 47 (39%), antibody to HBsAg (anti-HBs) was found in 37 (30%), and antibody to hepatitis B core antigen (anti-HBc) alone was present in 13 (11%). The relatives with the highest frequency of HBsAg positivity were the offspring of the propositus, followed by the nieces and nephews and the grandchildren. Anti-HBs and anti-HBc were detected most often in the spouses and non-blood relatives. Evidence for past and present hepatitis B virus (HBV) infection was more frequently found in the Asian family members when compared to the non-Asians. The e antigen (HBeAg) was present in 38% of the HBsAg positive individuals, including four with PHC; antibody to HBcAg (anti-HBe) was rarely detected. These results indicate that clustering of HBV infection was commonly present in family members of patients with PHC. The HBsAg positive individuals may be major contributors to the endemic pool of the virus, and may themselves be potential cases of chronic active type B hepatitis, cirrhosis, and PHC.     

HBV感染与原发性肝细胞癌的关系及临床意义

目的 探讨乙型肝炎病毒(HBV)感染与原发性肝细胞癌(PHC)的关系及临床意义.方法 选取240例PHC患者作为PHC组,480例健康体检者作为对照组,检测并分析两组研究对象的HBV感染情况,并采用多因素分析法探讨HBV感染与原发性肝细胞癌的关系.结果 PHC组患者的HBV感染阳性率、HBsAg阳性率、HBeAg阳性率、抗HBe阳性率、抗HBc阳性率均明显高于对照组(P﹤0.01),抗HBs阳性率明显低于对照组,差异均有统计学意义(P﹤0.01);经非条件Logistic回归分析结果显示:有PHC家族史、有饮酒史、合并HBV感染是发生PHC的独立危险因素(P﹤0.05).结论 PHC的发病风险由多种因素导致,其中,HBV感染是其重要的发病原因之一.     

Hepatitis B virus and primary hepatocellular carcinoma: Family studies in Korea

Chronic infection with hepatitis B virus (HBV) is closely associated with the etio-pathogenesis of primary hepatocellular carcinoma (PHC). It has been proposed that infection with HBV early in life, frequently transmited by an HBV-carrier mother, leads to persistent infection with HBV, which in turn is associated with the development of chronic active hepatitis (CAH), post-necrotic cirrhosis and PHC. If this view is correct, then there should be clustering of chronic carriers of HBV in families of patients with chronic liver disease. We tested this hypothesis in Korea by collecting serum from 132 patients with these chronic liver diseases admitted to the Seoul National University Hospital and 664 of their first-degree relatives. Controls (636) were members of two churches in Seoul and a rural village population; 261 of the controls were between the ages of 30 and 59, the age range that included 95% of the cases of chronic liver disease. Sera were assayed for hepatitis B surface antigen (HBsAg), antibody to HBsAg (anti-HBs) and antibody to hepatitis B core antigen (anti-HBc). Almost all cases showed evidence of present or past infection with HBV; 80% were HBsAg(+) and 14% were anti-HBs(+); 100% of 47 cases of PHC, 100% of 35 cases of cirrhosis, and 94% of 50 cases of CAH were anti-HBc(+); 6% of males and 4% of females in the control population (30–59 years of age) were HBsAg(+), 71% were anti-HBc(+), and 51% were anti-HBs(+), HBsAg(+) patients with chronic liver disease tended to be younger than HBsAg(?) patients with anti-HBs or anti-HBc antibodies. Mothers of patients were more frequently HBsAg(+) (9 of 33) than agematched women in the control population (0 of 34) or wives of patients (5 of 68). Five of 23 fathers were also HBsAg(+) compared with 1 of 25 age-matched controls. As first observed in Africa, there was a deficit of anti-HBs in the fathers of cases compared with the controls. Siblings of patients were frequently HBsAg(+) (45% of 154), with the highest prevalence in brothers (53%). Family history shows that five fathers, two mothers and five brothers of cases have died of PHC. These data are compatible with the hypothesis tested and lend further support to the view that prevention of infection with HBV will lead to a marked decrease in the incidence of CAH, cirrhosis and PHC in areas where these diseases are endemic. Members of the families of patients with these diseases are at high risk of developing persistent infection with HBV and chronic liver disease. It would be appropriate to focus preventive strategies on infants and children in such families.     

HBV、HCV在原发性肝癌发生中的相互作用研究

为了解河南省原发性肝癌（PHC）发生中HBV、HCV的相互作用，我们应用ELISA法和PCR法对PHC患者及其1：1对照进行了HBV标志物（HBVM）和HCV标志物（HCVM）检测。结果：PHC患者HBVM阳性率为81．25％，对照组HBVM阳性率为9．60％，P＜0.01，OR=70（25．36，193．23）；PHC患者HCVM阳性率为19．79%，对照组HCVM阳性率为8.33％，P＜0.05，OR＝2．57（1．11，5．95）；PHC患者HBVM、HCVM双重阳性率为18．75％，对照组双重阳性率为1.04％，将HBVM和（或）HCVM阳性看成不同的暴露等级与HBVM和HCVM均阴性组进行比较，得到HBV和HCV双重感染时的OR值为83.65，明显高于两者分别感染的OR值（34．85和1．58）之积。结果提示：HBV、HCV在PHC的发生中有显著的病因协同作用。     

Hepatitis B virus e antigen and primary hepatocellular carcinoma.

Serum samples from 243 cases of primary hepatocellular carcinoma (PHC) and 302 non-PHC hospital controls were tested for hepatitis B virus (HBV) surface antigen (HBsAg), antibody to HBsAg (anti-HBs), antibody to HBV core antigen (anti-HBc), HBV e antigen (HBeAg) and antibody to HBeAg (anti-HBe) with radioimmunoassays using commercial kits. A total of 236 (97%) PHC cases and 302 (100%) hospital controls were positive for one or more HBV markers. While 188 (77%) PHC cases and 57 (19%) controls were positive for HBsAg, 44 (18%) PHC cases and 5 (2%) controls were positive for both BHsAg and HBeAg. Statistically significant associations with PHC were observed for HBsAg and HBeAg with an odds ratio (OR) of 10.0 and 3.2, respectively, when age, sex and other markers were adjusted. The stratification analysis of interactive effects of HBV infection markers on the development of PHC showed that HBeAg carrier status may increase PHC risk associated with HBsAg status.     

Hepatitis B virus infection and primary hepatocellular carcinoma.

Ninety-three patients with biopsy-proven primary hepatocellular carcinoma (PHC) from Uganda, Zambia, and the United States were examined for serologic evidence of hepatitis B virus (HBV) infection. Patients were tested for hepatitis B surface antigen (HBsAg) and its antibody (anti-HBs), antibody to the hepatitis B core antigen (anti-HBc), hepatitis B e antigen (HBeAg), and its antibody (anti-HBe). Active HBV infection, as indicated by positive tests for HBsAg (with or without anti-HBs) and anti-HBc (without anti-HBs), was present in 62% of PHC patients (58 of 93), in contrast with 10% of African controls (9 of 90), and less than 1% of most United States adult populations reported in the literature. The presence of HBeAg or anti-HBe was rare among PHC patients and controls.     

Primary hepatocellular carcinoma in intertropical Africa: relationship between age and hepatitis B virus etiology

Clinical observations of patients with primary hepatocellular carcinoma (PHC) at Le Dantec Hospital, Dakar, Senegal, were studied to determine a correlation with hepatitis B virus (HBV) infection. Of the 103 patients with PHC, 80 had an active HBV infection (HBsAg and/or anti-HBc); 23 showed signs of previous HBV infection (anti-HBs and anti-HBc). The two groups were similar in the detection of alpha-fetoprotein (approximately 60%) and in the major clinical findings: hepatomegaly, 76.25% and 86.96%, respectively; and ascites, 57.50% and 47.83%, respectively. Jaundice, however, was three times more frequent (P < 0.01) in the group of patients with signs of active HBV replication. Distribution of HBV markers as a function of age at onset of PHC revealed that the presence of HBsAg was primarily confined to the sera of the younger patients (< 50 yr old). When compared with leprosy patients and blood donors, the younger PHC patients differed in the frequency of detection of HBsAg and anti-HBs. The older people (> 50 yr old) in the three groups (PHC patients, leprosy patients, and blood donors) had identical HBV markers.
