A 51-year-old male patient with chronic hepatitis B was referred to our hospital due to a 1-cm liver nodule on ultrasonography. Alpha-fetoprotein (AFP) was slightly elevated. The nodule showed prolonged enhancement on dynamic liver magnetic resonance imaging and appeared as a hyperintensity on both diffusion-weighted and T2-weighted imaging. The nodule was followed up because it was small and typical findings of hepatocellular carcinoma (HCC) were not observed in the dynamic imaging investigations. However, liver contrast-enhanced ultrasonography performed 1 month later showed enhancement during the arterial phase and definite washout during the delayed phase. Also, AFP had increased to over 200 ng/mL even though AST and ALT were decreased after administering an antiviral agent. He was presumptively diagnosed as HCC and underwent liver segmentectomy. Microscopy findings of the specimen indicated bile duct adenoma. After resection, the follow-up AFP had decreased to within the normal range. This patient represents a case of bile duct adenoma with AFP elevation mimicking HCC on contrast-enhanced ultrasonography.

<b>OBJECTIVEb>The aim of this study was to explore the diagnostic value of liver stiffness measurement combined with serum high-sensitivity C-reactive protein detection in HBV-related cirrhosis patients complicated with primary liver cancer.

<b>METHODSb>A total of 156 previously untreated chronic hepatitis B-related cirrhosis patients and 50 healthy subjects were included in this study. The 156 patients were divided into two groups: those with primary liver cancer (67 cases) and without liver cancer (89 cases). The 50 healthy subjects were considered as normal control group. Liver stiffness measurement (LSM) was conducted and serum high-sensitivity C-reactive protein (CRP) level was assayed in all the 156 patients and 50 normal individuals, and their measurement values were statistically compared and analyzed.

<b>RESULTSb>The LSM value was (39.72±29.05) kPa in the liver cancer patients, significantly higher than the (27.81±18.46) kPa in the cirrhosis alone patients and (4.25±0.74) kPa in the healthy controls (P<0.01 for both). Serum hs-CRP levels in the liver cancer patients was 5.81mg/L, significantly higher than 1.78 mg/L in the cirrhosis alone patients and 0.38mg/L in healthy controls, (P<0.01 for both). The higher the grade of LSM values was, the positive rate of CRP was higher in the cirrhosis patients complicated with primary liver cancer. In patients with LSM values ≥27.6 kPa, the serum CRP positive rate was 64.2% in patients with primary liver cancer, significantly higher than the 38.0% in patients with cirrhosis alone (P<0.01). In the 67 HBV-related cirrhosis patients complicated primary liver cancer, the LSM value and serum hs-CRP level in AFP-positive patients were (48.95±28.59) kPa and 4.91 mg/L, respectively, higher than those in the AFP-negative patients (28.64±26.83) kPa and 4.16 mg/L, but with a non-significant difference (P>0.05).

<b>CONCLUSIONb>Liver stiffness measurement combined with serum high-sensitivity C-reactive protein detection may have potential diagnostic implications as a marker of primary liver cancer occurrence in patients with HBV-related cirrhosis.

<b>OBJECTIVEb>To identify non-invasive biomarkers for diagnosis and/or prognosis of liver fibrosis in chronic hepatitis B (CHB).

<b>METHODSb>Peripheral blood samples were obtained from 48 patients with CHB, including 24 with mild fibrosis (stage 1, S1) and 24 with severe fibrosis (stage 4, S4), and subjected to Ficoll density gradient centrifugation in order to obtain enriched samples of peripheral blood mononuclear cells (PBMCs).The PBMC proteomes of the two groups were assessed by first separating the total proteins by two-dimensional gel electrophoresis (2DE) and then identifying the differentially expressed proteins by liquid chromatography combined with tandem mass spectrometry (LCMS/MS).

<b>RESULTSb>The enriched PBMC samples from the S1 group and the S4 group had similar amounts of platelets [(19.268+/- 6.413) * 109/L and(19.480+/- 6.538) * 109/L, respectively); however, for both, the platelet amounts were 5 to 15-fold lower than that of the normal reference (100-300 *109/L). There was no significant difference found between the platelet amounts in the S1 patients and healthy controls (P=0.930). Twelve differentially expressed proteins were identified through 2DE-LC-MS/MS, including proteins such as moesin and NADH dehydrogenase [ubiquinone] iron-sulfur protein 3 that are involved in various biological processes like cell movement, cell adhesion, kinase signaling and transcription.

<b>CONCLUSIONb>s The 12 proteins with differential expression in S1 and S4 patients with CHB and liver fibrosis may represent markers related to development and/or progression of liver fibrosis.

MicroRNA polymorphisms may be associated with carcinogenesis or immunopathogenesis of infection. We evaluated whether the mircoRNA-604 (miR-604) polymorphism can affect the persistence of hepatitis B virus (HBV) infection, and the development to hepatocellular carcinoma (HCC) in patients with chronic HBV infection. A total of 1,439 subjects, who have either past or present HBV infection, were enrolled and divided into four groups (spontaneous recovery, chronic HBV carrier without cirrhosis, liver cirrhosis and HCC). We genotyped the precursor miR-604 genome region polymorphism. The CC genotype of miR-604 rs2368392 was most frequently observed and T allele frequency was 0.326 in all study subjects. The HBV persistence after infection was higher in those subjects with miR-604 T allele (P=0.05 in a co-dominant and dominant model), which implied that the patients with miR-604 T allele may have a higher risk for HBV chronicity. In contrast, there was a higher rate of the miR-604 T allele in the chronic carrier without HCC patients, compared to those of the HCC patients (P=0.03 in a co-dominant model, P=0.02 in a recessive model). The T allele at miR-604 rs2368392 may be a risk allele for the chronicity of HBV infection, but may be a protective allele for the progression to HCC in chronic HBV carriers.

BACKGROUND/AIMS: Apolipoprotein E (ApoE) plays an important role in regulating lipid and lipoprotein metabolism, and ApoE genotypes are known to affect plasma lipoprotein concentrations. We investigated whether ApoE genotype determines the disease outcome in hepatitis B virus (HBV)-infected individuals, and verified the association between ApoE genotype and the occurrence of hepatocellular carcinoma (HCC) in patients with chronic liver diseases of various etiologies. METHODS: This hospital-based, case-controlled study enrolled 156 subjects (47 healthy controls, 50 HBV-related liver cirrhosis patients, and 59 HCC patients). ApoE genotypes were determined using PCR-based ApoE genotyping kits. The biological significance of ApoE genotype was verified by measuring serum ApoE levels using an ELISA kits. RESULTS: The epsilon3 allele was the most common allele, with allele frequencies among the entire cohort of 5.8%, 84.3%, and 9.9% for the epsilon2, epsilon3, and epsilon4 alleles, respectively. Significantly more of those patients carrying the epsilon3/3 genotype had developed liver cirrhosis compared to the control subjects. Being an ApoE4 carrier was associated with a lower probability of developing liver cirrhosis. The allele frequencies and genotype distribution of ApoE did not differ significantly between the liver cirrhosis and HCC patients. The serum level of ApoE was significantly higher in patients with liver cirrhosis than in the healthy controls, but did not differ significantly with the ApoE genotype. CONCLUSIONS: The ApoE epsilon3/3 genotype frequency was higher in patients with HBV-associated liver cirrhosis than in the controls.

Castleman's disease is a rare disease characterized by lymph node hyperplasia. Although Castleman's disease can occur wherever lymphoid tissue is found, it rarely appears in the abdominal cavity, and is especially rare adjacent to the liver. Here, we report a rare case of Castleman's disease in the portal area that mimicked a hepatocellular carcinoma (HCC) in a chronic hepatitis B patient. A 40 year-old woman with chronic hepatitis B presented with right upper quadrant discomfort. Computed tomography and magnetic resonance imaging results showed a 2.2 cm-sized, exophytic hypervascular mass in the portal area. HCC was suspected. However, histologic examination revealed Castleman's disease. We suggest that Castleman's disease should be included as a rare differential diagnosis of a hypervascular mass in the portal area, even in patients with chronic hepatitis B.

<b>OBJECTIVEb>To study the changes of experimental markers of hepatic fibrosis in patients with chronic hepatitis B treated by Dahuang Zhechong Wan combined with adefovir dipivoxil.

<b>METHODb>Ninty and four cases of chronic viral hepatitis B patients were randomly divided into two groups. The treatment group (50 cases) was orally given 10 mg of adefovir dipivoxil once a day, 1 Wan each time, combined with Dahuang Zhechong Wan, 3 times a day, 1 Wan each time. And the control group (44 cases) was treated with adefovir dipivoxil alone, 6 months as a course.

<b>RESULTb>Both the difference of liver fibrosis indexes between the treatment group and the control group and before and after the treatment in the treatment group had statistical significance (P < 0.01 or P < 0.05). Both the difference of experimental markers such as ALT, AST, GGT, TBIL between the treatment group and the control group and before and after the treatment in the treatment group had statistical significance (P < 0.01).

<b>CONCLUSIONb>Dahuang Zhechong Wan combined with adefovir dipivoxil could prevent hepatic fibrosis in patients with chronic hepatitis B, reduce the incidence of liver cirrhosis, improve life quality and prognosis.

PURPOSE: Using FibroScan(R) to obtain a reliable liver stiffness measurement (LSM) may require more than 10 valid measurements (VMs), according to the manufacturer's recommendations. However, this requirement lacks scientific evidence in support thereof. We investigated the minimal number of VMs required to assess liver fibrosis without significant loss of accuracy in patients with chronic hepatitis B (CHB) and C (CHC) and predictors of discordance between LSM and liver biopsy (LB). MATERIALS AND METHODS: Between January 2005 and December 2009, we prospectively enrolled 182 patients with CHB and 68 patients with CHC who were to undergo LB and LSM before starting antiviral treatment. Only LSMs with at least 10 VMs were considered reliable. The Batts and Ludwig scoring system was used for histologic assessment. RESULTS: The mean age and body mass index were 46.0 years and 23.4 kg/m2 in patients with CHB and 49.7 years and 23.1 kg/m2 in those with CHC, respectively. The median elasticity scores from the first 3, first 5, and all VMs taken significantly predicted fibrosis stages > or =F2 and F4 (all p<0.05) without significant differences (all p>0.05 by DeLong's method). Alanine aminotransferase (ALT) was the only predictor of discordance in fibrosis stage as estimated by the median elasticity score from the first 3 VMs and by LB in patients with CHB, whereas no significant predictor was identified in those with CHC. CONCLUSION: After comparison of patients who had more than 10 valid measurements for LSM, three VMs may be enough to assess liver fibrosis using LSM without significant loss of accuracy in patients with CHC and patients with CHB. However, ALT should be considered when interpreting LSM for patients with CHB.
