对原发性肝癌(PHC)58例,良性肝病62例(包括肝硬化31例,肝血管瘤10例,慢活肝15例,急性肝炎,6例),转移性肝癌10例,正常对照30例。检测血清γ-谷氨硫胺转换酶同功酶Ⅱ(γ-GTⅡ),并且与甲胎蛋白(AFP)及AFP异质体对照。结果显示γ-GTⅡ对PHC有较高的敏感性和特异性,与AFP联合检测可以提高AFP阴性的PHC患者的诊断率,同时还可用以小肝癌的诊断及观察PHC的治疗效果。     

Serum α-l-fucosidase

Forty-nine liver disease patients (7 chronic persistent hepatitis, CPH; 10 chronic active hepatitis, CAH; 13 liver cirrhosis, LC; 9 primary hepatocellular carcinoma, PHC, without LC; and 10 PHC with associated LC) and 20 controls were assessed for their serum alpha-L-fucosidase (ALF) and alpha-fetoprotein (AFP) levels and several routine liver injury parameters. Tumor diameter in those with hepatic cancer was assessed by angio-CT. Only ALF and AFP were significantly greater in patients with PHC and PHC + LC patients as compared to patients with LC alone. At an accepted cutoff level of 500 ng/ml, the AFP level provided 43% false negative tests. On the other hand, an ALF level exceeding 740 mumol/hr/ml provided a sensitivity of 84% with a specificity of 94%. No relationship between the ALF level and Child's criteria or with any liver injury parameter was evident. Considering all individual values, the ALF, rather than the AFP, correlated with tumor size. This finding suggests the ALF level may be of value in the early detection of PHC as well as in the follow-up of patients treated for PHC.     

甲胎蛋白在原发性肝癌首诊中的价值

目的探讨甲胎蛋白（AFP）在原发性肝癌首诊中的诊断价值。方法回顾性分析177例临床资料相对完善的最终确诊为原发性肝癌（PHC）患者首诊时的AFP及影像学结果,以2011年收治的98例慢性乙型肝炎、82例乙型肝炎肝硬化患者为对照组。计数资料采用χ2检验。结果177例PHC患者首诊时AFP≥400 ng／ml 93例,20 ng／ml ＜AFP＜400 ng／ml 38例,正常46例,分别占5254%、21.47%、25.99%,异常率占74.01%,显著高于慢性乙型肝炎组（χ2=106.07,P＜0.001）和乙型肝炎肝硬化组（χ2=67.82,P＜0.001）;177例患者中63例病程中AFP＜400 ng／ml,占35.59%;肿瘤直径≤3 cm患者的AFP水平低于直径＞5 cm患者（χ2=862,P＜0.005）;首诊时AFP确诊率低于B超 （χ2=30.39,P＜0.000）和CT （χ2=84.83,P＜0.000）。结论PHC患者首诊时AFP异常率较高,且AFP水平越高,其诊断价值越大,AFP水平与肿瘤大小有一定关系;也要警惕AFP阴性的PHC;动态监测AFP并结合影像学检查有利于早期诊断,以减少漏诊误诊。     

转化生长因子β1对原发性肝癌诊断价值的初步探讨

为了解转化生长因子β１（ＴＧＦβ１）在原发性肝癌中的诊断意义，用酶联免疫吸附试验法（ＥＬＩＳＡ）测定了４７例原发性肝癌（ＰＨＣ）、７７例其他各种肝病和消化道恶性肿瘤及２０例正常对照者的血清ＴＧＦβ１水平。结果：ＰＨＣ血清ＴＧＦβ１水平明显高于正常对照及其他各病组（Ｐ值分别＜０．０５或０．０１）。血清ＴＧＦβ１诊断ＰＨＣ的敏感性和特异性分别为７２．３％和７７．９％，甲胎蛋白（ＡＦＰ）阴性ＰＨＣ诊断阳性率为７８．６％，其中７例小肝癌有５例（７１．４％）血清ＴＧＦβ１阳性，与ＡＦＰ联合检测可提高ＰＨＣ诊断阳性率，达９３．６％。血清ＴＧＦβ１作为一种新的ＰＨＣ血清标志物应用于ＰＨＣ的诊断、监测和疗效判断，尤其是对ＡＦＰ阴性或早期肝癌的诊断，有重要临床意义。     

Pharmacokinetics of roxatidine acetate in patients with chronic liver disease

BACKGROUND AND AIM: Patients with liver disease are prone to develop peptic ulceration and often receive H(2)-receptor antagonists. Therefore, it is important to clarify whether the pharmacokinetics of H(2)-receptor antagonists is affected by hepatic function. However, pharmacokinetics of a new H(2)-receptor antagonist, roxatidine acetate, in chronic liver disease has not been well known. In this study, we analyzed the pharmacokinetics of roxatidine in patients with liver disease. METHODS: Blood samples were obtained from 11 patients with chronic hepatitis, 11 patients with cirrhosis and six healthy subjects. Under fasting conditions, 75 mg of roxatidine acetate was administered orally, and plasma roxatidine levels were determined sequentially from 3 to 12 h. Relationships between pharmacokinetic variables and each parameter related to hepatic functions were also investigated. RESULTS: There was no difference in the pharmacokinetic variables and serum levels of roxatidine between chronic hepatitis and healthy controls. In contrast, in cirrhosis, serum roxatidine levels were significantly higher than those in chronic hepatitis and normal control. Half-life, the area under the plasma concentration-time curve and clearance in cirrhosis were also significantly longer, bigger and smaller than those in chronic hepatitis and healthy controls, respectively. The half-life became longer and the clearance became smaller in parallel with the progression of liver disease. Serum levels of hyaluronate and gamma-glutamyl transpeptidase showed a good correlation with half-life, clearance and elimination rate. A good correlation between creatinine clearance and elimination rate was found. CONCLUSION: Pharmacokinetics of roxatidine acetate is affected by hepatic function, and the dosage of roxatidine acetate for patients with liver disease, especially cirrhosis, should be modified.     

Increased intrahepatic and circulating levels of endoglin, a TGF-beta1 co-receptor, in patients with chronic hepatitis C virus infection: relationship to histological and serum markers of hepatic fibrosis

Endoglin, a transforming growth factor (TGF)-beta1 co-receptor, has been associated with renal and cutaneous fibrosis, as overexpression of this protein has been observed in biopsies from patients with glomerulosclerosis and scleroderma, respectively. Our aim was to evaluate whether endoglin may be associated with hepatic fibrosis featuring chronic hepatitis C virus (HCV) infection. Fifty-two anti-HCV+ patients, five anti-HCV- patients and 27 healthy subjects were studied. Western blot and immunohistochemistry were used to quantify the expression levels of endoglin and TGF-beta1 in liver biopsy samples, and serum concentrations of endoglin and hyaluronic acid were determined by enzyme-linked immunosorbent assays (ELISAs). In patients with advanced fibrosis, intrahepatic expression levels of endoglin and TGF-beta1 were significantly higher than those in patients with early fibrosis (mean: 3- and 5.8-fold, respectively) and normal liver (mean: 3.9- and 12-fold, respectively). Interestingly, activated hepatic stellate cells as well as portal and septal myofibroblasts expressed endoglin. Serum levels of endoglin were also significantly higher in patients with advanced fibrosis than in those with early fibrosis (55.5 +/- 1.6 vs 47.5 +/- 0.9 ng/mL, P < 0.001), showing a positive correlation with serum hyaluronic acid concentrations (r = 0.57, P = 0.01). In conclusion, increased intrahepatic endoglin and TGF-beta1 expression is significantly associated with progressive hepatic fibrosis in chronic HCV infection. Circulating endoglin levels are elevated in HCV patients showing a significant correlation with histological and serum markers of hepatic fibrosis. These data suggest an active role for endoglin in the fibrotic process featuring chronic HCV infection.

Human parvovirus B19 infection in patients with chronic hepatitis B or hepatitis C infection

BACKGROUND AND AIM: Parvovirus B19 has been reported to be detected in the sera of patients with acute or chronic hepatitis. The prevalence and clinical significance of B19 DNA in serum samples from patients with chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection were investigated. METHODS: Serum samples from 54 patients with HBV infection, 51 with HCV infection and 53 normal controls were examined for anti-B19 antibodies and B19 DNA by enzyme-linked immunosorbent assay (ELISA), the nested polymerase chain reaction (PCR), Southern blotting and direct nucleotide sequencing, respectively. RESULTS: Anti-B19 IgM and IgG antibodies were detected in 19 (35.2%) and 46 (85.2%) of 54 serum samples from patients with HBV infection, and eight (15.7%) and 36 (70.6%) of 51 serum samples from patients with HCV infection. B19 DNA was detected in serum samples of 20 (37%) of 54 patients with HBV infection and 12 (23.5%) of 51 patients with HCV infection, but not in 53 serum samples from normal controls. The occurrence of liver dysfunction was not affected by B19 infection in patients with HBV and HCV infection (P > 0.05). All of the 20 serum samples with B19 DNA from patients with chronic HBV infection and all of the 12 serum samples with B19 DNA from patients with chronic HCV infection exhibited TW-3 subtype and TW-9 subtype, respectively. The variant subtypes of B19 were found to be distinctive in patients with HBV or HCV infection. CONCLUSIONS: These data revealed that human parvovirus B19 infection was frequently found in patients with chronic HBV or HCV infection. The variant genotypes were present in patients with different chronic hepatitis. The coinfection of B19 with HBV or HCV did not increase the frequency of liver dysfunction in patients with chronic hepatitis. Long-term longitudinal studies are required to determine the natural course of parvovirus B19 infection and whether its coinfection affects the natural history of chronic hepatitis B or hepatitis C.     

原发性肝癌患者血清VEGF、TGF-β1表达水平与浸润转移关系的研究

目的探讨原发性肝癌患者血清血管内皮生长因子（VEGF）及转化生长因子-β1（TGF-β1）的表达水平与肝癌浸润和转移的相关性。方法采集98例原发性肝癌患者和4O例健康志愿者的血清。应用ELISA法检测受检者血清VEGF、TGF-β1的表达水平,并分析其与临床病理因素之间的关系。结果原发性肝癌患者血清VEGF与TGF-β1水平显著高于正常对照组（P〈0.01）,患者血清VEGF、TGF-β1的表达水平与患者与肿瘤的组织学分级、浸润深度、转移密切相关（P〈0.01）。血清VEGF与TGF-β1水平呈显著正相关（r=0.418,P〈0.01）。结论VEGF和TGF-β1与原发性肝癌的病情发展、浸润和转移有密切相关性,临床上,血清VEGF、TGF-β1的表达水平可作为了解原发性肝癌生物学行为和判断预后的指标。     

Glycylproline dipeptidyl aminopeptidase isoenzyme in diagnosis of primary hepatocellular carcinoma

AIM: To investigate the role of glycylproline dipeptidyl aminopeptidase (GPDA) isoenzyme in the diagnosis of primary hepatocellular carcinoma (PHC), especially in patients with negative alpha-fetoprotein (AFP). METHODS: A stage gradient polyacrylamide gel discontinuous electrophoresis system was developed to separate serum GPDA isoenzymes, which were determined in 102 patients with PHC, 45 cases with liver cirrhosis, 24 cases with chronic hepatitis, 35 cases with benign liver space-occupying lesions, 20 cases with metastatic liver cancer and 50 cases with extra-hepatic cancer, as well as 80 healthy subjects. The relationships between GPDA isoenzymes and AFP, the sizes of tumors, as well as alanine aminotransferase (ALT) were also analyzed. RESULTS: Serum GPDA was separated into two isoenzymes, GPDA-S and GPDA-F. The former was positive in all subjects, while the latter was found mainly in majority of PHC (85.3 %) and a few cases with liver cirrhosis (11.1 %), chronic hepatitis (33.3 %), metastatic liver cancer (15.0 %) and non-hepatic cancer (16.0 %). GPDA-F was negative in all healthy subjects and patients with benign liver space-occupying lesions, including abscess, cysts and angioma. There was no correlation between GPDA-F and AFP concentration or tumor size. GPDA-F was consistently positive and not correlated with ALT in PHC, but GPDA-F often converted to negative as decline of ALT in benign liver diseases. The electrophoretic migration of GPDA-F became sluggish after the treatment of neuraminidase. CONCLUSION: GPDA-F is a new useful serum marker for PHC. Measurement of serum GPDA-F is helpful in diagnosis of PHC, especially in patients with negative AFP. GPDA-F is one kind of glycoproteins rich in sialic acid.
