Furthermore, coincubation with L365,260, a gastrin receptor (CCK2) antagonist, attenuated the upregulation of namely ��-catenin by greater than 50%, suggesting that the increase in ��-catenin was specific (Figure 1C). An induction of ��-catenin was consistently detected, and the results were reproduced on four separate occasions. Although the magnitude of the change in total ��-catenin protein varied within individual experiments, a 3�C4-fold increase in total ��-catenin protein levels was detected when bands were quantified by densitometry and normalised to ��-actin levels (Figure 1D). Figure 1 (A) Gastrin does not affect ��-catenin mRNA levels, as demonstrated by Northern blot analysis. MC-26 cells were incubated for 4h in the presence of increasing concentrations of G-17 (10�C100nM; upper panel).

28S and 18S … As mentioned above, nuclear accumulation of ��-catenin represents a key event in CRC progression. To examine whether G-17 can enhance nuclear ��-catenin in MC-26 cells, cells were treated with G-17 for 4h and nuclear extracts were prepared. In all, 20 and 50nM G-17 induced approximately a two-fold increase in nuclear ��-catenin levels (Figure 1E), suggesting that G-17 promotes nuclear translocation of ��-catenin. Expression of Sp1, a ubiquitously expressed transcription factor, was used as a loading control for nuclear extracts. Gastrin-17 increases LEF-1-dependent transcriptional activity To examine whether the increase in nuclear ��-catenin protein is also associated with the activation of LEF-1, LEF-1-dependent reporter assays were performed.

The pGL3-LEF-1 luciferase construct (kindly provided by Dr R Grosschedl, Munich, Germany) contains eight repeats of the LEF binding site that is activated only in the presence of an exogenous LEF-1 construct. The level of LEF-1-dependent transcription is also dependent on nuclear ��-catenin levels, as ��-catenin is a known coactivator for TCF/LEF transcription factors. As we speculated that an increase in ��-catenin protein by G-17 might be functionally important for the transcriptional activation of its target genes, LEF-1-dependent reporter assays were performed in the absence and presence of G-17. We observed that 20 and 50nM G-17 induced a concentration-dependent increase in LEF-1-dependent transcriptional activity (P0.005) (Figure 2).

In addition, the effects of gastrin on cyclin D1, one of the target genes of ��-catenin-dependent transcription, were analysed. In response to the inclusion of G-17 in the culture medium, both cyclin D1 protein levels and promoter activity were increased (Figure 3). Specifically, 50nM G-17 significantly enhanced the activity of the Dacomitinib full-length cyclin D1 promoter (?1745) when compared to either the empty or minimal promoter (?66) (Figure 3B, P0.01). Figure 2 Gastrin-17 enhances LEF-1-dependent transcriptional activity.

Sections were rinsed twice in ��1 PBS, acetylated for 10 min with 0.25% acetic anhydride/0.1 m triethanolamine, dehydrated in a graded series of ethanol/dietyl pyrocarbonate (DEPC)-treated water selleck products rinses and air dried. Hybridization was carried out overnight at 55��C with sense or antisense digoxigenin-labelled (labelling-kit; Roche Diagnostics, Basel, Switzerland) RNA probes (2 ��g/ml) diluted in hybridization buffer, which contained 50% deionized formamide, ��4 saline sodium citrate (SSC) (��1 SSC; 0.15 m NaCl, 15 mm sodium citrate, pH 7.0), 10% dextran sulfate, ��1 Denhardt’s solution, 0.5 mg/ml salmon sperm DNA, 0.25 mg/ml yeast tRNA and 10 mm dithiothreitol. Following hybridization, sections were washed in ��0.2 SSC for 50 min at 72��C and incubated with RNAse (20 ��g/ml) for 30 min at 37��C.

Hybridization signal was visualized using anti-digoxigenin-alkaline phosphatase-conjugated antibodies (Roche Diagnostics, Basel, Switzerland) and nitro-blue tetrazolium/5-bromo-4-chloro-3-indolyl-phosphate (NBT/BCIP) as a substrate. Results AhR-null mice had important hepatic alterations. As it can be observed in Fig. 1, whereas hepatic portal fibrosis were markedly visible in AhR?/? mice, AhR+/+ mice showed no apparent liver damage (Fig. 1a,b). We have used collagen deposition around the periportal areas as a fibrotic marker in liver. Fig. 1(a,b) shows atrophy of the tissue surrounding the portal triad (arrow). Sirius red staining of AhR?/? liver sections reflected an increase in collagen content in the portal triads, which was not observed in AhR+/+ mice.

No significant collagen staining was found in other areas of the liver. The altered structure of the portal triads in AhR?/? mice also affected the diameter of the bile duct. Thus, whereas in AhR+/+ mice, the bile duct had a diameter of 54 �� 27 ��m (n = 7), in AhR?/? mice, this value increased to 106 �� 34 ��m (n = 7). Figure 1 Histology of normal and fibrotic mice livers. Serial 4-��m frozen sections containing a typical portal triad were prepared from wild-type AhR (AhR+/+) and null AhR (AhR?/?). (Panels A, B) Collagen was localized (red) by Fast green/Sirius … Because the fibrotic nodule was big enough, we could obtain several sections from the same area of the liver. Thus, the same fibrotic area was used to analyse ��-actin and vimentin protein expression, which should be selectively expressed by the fibroblasts present at the damaged site.

Immunostaining signals for ��-actin and vimentin Entinostat were markedly increased in AhR?/? with respect to AhR+/+ liver (Fig. 1c�Cf, respectively). Moreover, the expression of both proteins was limited to the fibrotic areas previously found to be positive for Sirius red staining (compare Fig. 1b,d,f). In addition, another relevant marker for fibrogenesis, fibronectin, was also increased in the portal region of AhR?/? liver (Fig. 1g,h).

The intraday and interday precision of the method was 6.4% and 7.5%, respectively, with an accuracy of >95%. The limit of quantitation was 0.15 pmol/ml urine. Data Management Lenalidomide IC50 and Analysis Data were entered into a Microsoft Access database. Duplicate data entry was performed to ensure quality control. Descriptive data analysis was conducted to examine the ranges and distribution of continuous variables. Data were examined for normality using the Shapiro�CWilk normality test: NNAL values were skewed and were described as geometric means. Student��s t test (continuous variables) and chi-square test (categorical variables) were used to compare demographics and smoking behavior variables between cigarette and waterpipe smokers, and characteristics of exposure to ETS between nonsmoking females exposed either to cigarette or waterpipe smoke.

When the expected numbers were small (<5 subjects per cell), Fisher��s exact method was used. Mann�CWhitney and Kruskal�CWallis tests were used to evaluate the differences in the levels of NNAL in binary and categorical variables respectively. Spearman��s correlation coefficients were calculated to determine the association between levels of NNAL in nonsmoking females exposed to tobacco smoke and NNAL levels in their husbands and with the number of cigarettes/hagars they smoked in the past 24 hr. SPSS statistical software (release 15) was used for data analysis. All statistical tests were two sided, with 0.05 as the level of significance. Results A total of 51 subjects were recruited, of whom 46 were successfully assayed: 24 (52.

2%) were males and 22 (47.8%) were nonsmoker wives. The demographic characteristics and smoking profiles of participants are shown in Table 1. Of the 24 current male smokers, 13 (54.2%) were exclusive cigarette smokers, and 11 (45.8) were exclusive waterpipe smokers. Among nonsmoking females, 13 (59.1%) reported being exposed to cigarette smoke, and 9 (40.9%) reported exposure to waterpipe smoke. All interviewed subjects were married; the majority had received no formal education (62.5% in males and 72.7% in nonsmoking females). The mean age was 45.3 �� 10.4 (range 24�C60 years) in cigarette smokers and 45.4 �� 15.9 (range 20�C65 years) in waterpipe smokers (p > .05). The mean age was 36.1 �� 11.7 (range 21�C60 years) in nonsmoking females who reported exposure to cigarette smoke and 43.

1 �� 11.5 (range 24�C57 years) in nonsmoking females exposed to waterpipe smoke (p > .05). Table 1. Study Subject Characteristics by Smoking Status (n = 46) Both cigarette and waterpipe smokers had similar ages of smoking initiation and number of years of smoking (p > .05). On average, cigarette smokers consumed 21.5 �� 7 cigarettes/day, and waterpipe smokers consumed 11.9 �� 11 Brefeldin_A hagars (tobacco wads) per day. The mean FTND was 4.5 �� 1 in cigarette smokers, similar to previous studies (Park et al. 2004; Spitz et al.

Thus, further confirmative Phase III trials will be needed. Nausea and hand-foot syndrome were the most common side effects of treatment, and hematologic toxicity was limited to Grades 2 and 3. The mildness of the observed toxicity may be attributable to the less aggressive starting dose of capecitabine (1,000 17-AAG side effects mg/m2) used for this group of patients. The use of 1,000 mg/m2 capecitabine has become common in the treatment of patients with other malignancies, such as colorectal carcinoma; this reduced dose was suggested by Borner et al.,29 who also recommended the use of 1,000 mg/m2 twice daily when capecitabine is used in combination with oxaliplatin. Although impaired hepatic function can exacerbate toxicity or inhibit the efficacy of many agents, the presence of mild-to-moderate hepatic dysfunction had no clinically significant effect on the pharmacokinetics of capecitabine and its metabolites.

17 This finding suggests that the CapGem regimen may be useful for patients with hepatobiliary carcinoma, including patients with mildly-to-moderately impaired hepatic function. Further research in this area should be directed at finding the best cytotoxic agent for combination with capecitabine or gemcitabine, or altering the dose intensity or route of administration in advanced gallbladder cancer. A larger trial of gemcitabine combined with cisplatin compared with CapGem needs to be conducted. Also, the role of the CapGem combination as an adjuvant treatment for suboptimally resected patients should be further pursued.

Hepatic encephalopathy (HE) is presented clinically as a combination of neuropsychiatric abnormalities characterized by alterations in mental status, personality, intellectual function, and changes in neuromuscular activity. It is frequently observed in those with both acute liver failure and liver cirrhosis.1 The pathogenesis of the syndrome is complex, but ammonia produced by intestinal bacteria is known to play an important role in its pathogenesis. The treatment of HE has focused on reducing both the production and absorption of gut-derived ammonia. Presently, non-absorbable disaccharides and antibiotics are the mainstay of therapy.2,3 However, currently used drugs have several limitations. For example, neomycin, a poorly-absorbed aminoglycoside may cause nephrotoxicity and ototoxicity,3 and lactulose treatment may be complicated by excessive diarrhea and abdominal pain.

4,5 Rifaximin (4-deoxy-4′-methylpyrido-(1′,2′-1,2)-imidazo-(5,4C)-rifamycin SV) is a derivative of rifamycin, which acts by inhibiting bacterial ribonucleic acid (RNA) synthesis. Rifaximin is virtually unabsorbed after oral administration and exhibits broad spectrum antimicrobial activity against both aerobic and anaerobic gram-positive Cilengitide and gram-negative microorganisms within the gastrointestinal tract.6 During the past decade, several European studies have proved the efficacy of rifaximin for the treatment of HE in Caucasian patients.

, 2001, 2002; De Wit & Stewart, 1981). The results obtained with [11C]raclopride binding confirm other reports in the literature but there were some surprises. Smoking denic cigarettes reduced inhibitor Nutlin-3a [11C]raclopride binding in the striatum as expected because of its cue-related smoking effects. One possibility is that the many chemicals in tobacco smoke with very small amounts of nicotine are important salience cues. Only some regions of the right hemisphere showed a significant increase in DA release with denic smoking when an uncorrected p < .001 was used. However, with a strict statistical criterion using a p FDR corrected to p < .02, smoking nic cigarettes increased striatal DA release but more on the left, consistent with previous research (Brody et al., 2004).

In the present study, only one region in the left caudate showed a weak (p < .05) correlation between an increase in plasma nicotine and increased DA release. Berridge, Espana, and Stalnaker (2004) described the brain asymmetry of DA efferents within the prefrontal cortex in regard to coping and stress in rodents. They suggested in humans that DA in the right hemisphere may play a unique role in affective and cognitive processes. Furthermore, right hemisphere damage in humans produces unique disorders of communication and cognition (Myers, 1999). In one word, the right brain is concerned with ��gestalt.�� The fact that nic smoking had marked bilateral striatal release effects, of which release DA in one area correlated with increased venous plasma nicotine, is further evidence of a pharmacological role of nicotine.

Marti et al. (2011) found that tobacco smoke extracts that contain nicotine, as well as nicotine alone, enhance triggered DA ventral tegmental area neurons in anesthetized wild type (WT) mice, but weak and inhibitory firing occurred with tobacco extracts. In ��2?/? knockout mice, nicotine or tobacco smoke had no effect on the firing patterns of DA neurons. However, the differences between DA neuron firing produced by tobacco extract/tobacco smoke or nicotine alone observed in the WT animals persisted in the ��6?/? mice but not in the ��4?/? mice. Marti et al. (2011) concluded that tobacco smoke or nicotine alone act through ��4��2 nicotinic cholinergic receptors (nAChRs) and that tobacco extract may contain unknown chemicals that antagonize the effects of nicotine.

Whether denic cigarette smoke contains substances that affect ��6?/? nAChRs needs further research. Entinostat Another important issue is whether the very low venous plasma nicotine levels after smoking denic cigarettes are sufficient to cause any brain effects. Brody et al. (2006) used the 18F derivative of A-85380, a selective PET ��4��2 nicotine cholinergic ligand, to demonstrate the effects of tobacco smoking on brain nAChRs. Smoking just one regular tobacco cigarette produced more than 88% receptor occupancy. A venous plasma nicotine concentration of only 0.

Primary screening led to the exclusion of 390 articles for the following reasons: reviews (218), other agents/regimens (43), radiotherapy/chemoradiation (99), letters/comments/editorials [26] or case reports [4]. The remaining 372 papers were retrieved for more detailed evaluation. Of these, 144 articles were excluded because selleckbio of adjuvant chemotherapy, 44 for biliary tract cancer, 110 for phase I clinical trials, 38 for not-controlled design and 2 for repeated reports [6,7]. In the end, a total of 35 randomized clinical trials [8-42] were eligible for inclusion in our analysis (Figure (Figure11). Figure 1 Flow chart for trials selection in the meta-analysis. Characteristics of the trials included in the present analysis Thirty-five trials were included in the present analysis, with a total of 9, 979 patients accrued.

Characteristics of the eligible trials are listed in Table Table1.1. Most of the trials (34/35, 97%) evaluated gemcitabine-based chemotherapy for first line or palliative chemotherapy in LA/MPC patients, whereas one trial (Palmer 2007) evaluated neoadjuvant chemotherapy. Twenty-three trials compared single-agent gemcitabine with gemcitabine combined with other cytotoxic agents, nine trials studied gemcitabine monotherapy with gemcitabine plus targeted therapy, and three trials evaluated triplet therapy for LA/MPC patients. Table 1 Characteristics of the eligible trials included in the meta-analysis Among the thirty-five trials, the distribution of baseline patient characteristics was homogeneous. The percentage of patients with metastatic disease ranged from 50% to 91.

1%, while the median age of patients varied from 57.8 to 66 (range: 23-96). The details of chemotherapeutic regimens per arm in each trial are shown in Table Table22. Table 2 Regimens of the trials included in this analysis. Trials comparing single-agent gemcitabine with gemcitabine combined with other cytotoxic agents This analysis evaluated 23 trials (5,577 patients) comparing single-agent gemcitabine with gemcitabine-based Brefeldin_A combinations with other cytotoxic agents. For the primary endpoint of OS, the gemcitabine-based combination therapy was associated with significantly better outcome (ORs, 1.15; 95% CI, 1.03-1.28; p = 0.011) than gemcitabine in monotherapy (Figure (Figure2A).2A). The analysis of PFS also afforded favorable results for the combination arm, with the ORs being 1.27 (95% CI, 1.14-1.42; p < 0.001) (Figure (Figure2B).2B). A similar advantage for gemcitabine-based combinations was observed in terms of the ORR (ORs, 1.58; 95% CI, 1.31-1.91; p < 0.001), with no significant heterogeneity (p = 0.79). Figure 2 Comparison of gemcitabine-X combination with gemcitabine alone. A, OS; B, PFS.

Because SHAPS scores demonstrated a small, but significant association with PANAS-NA, any associations demonstrated between the SHAPS and the measures of smoking motivation could potentially be explained by covariance accounted for by affective distress. Accordingly, these correlations were recomputed as partial correlations, which adjusted for PANAS-NA scores, Erlotinib price to examine if associations were specific to the appetitive aspect of anhedonia and not explained by any potential overlap with aversive affect. Although the PANAS-positive affect scale was also measured at baseline, analyses do not control for this variable because the constructs of positive affect and anhedonia are strongly overlapping. Similarly, analyses do not control for overall depressive symptoms because measures of depressive symptomatology typically include items assessing anhedonia and positive affect.

Thus, covaring for positive affect or depressive symptoms may partial out relevant variance linked with the appetitive aspects of the anhedonia construct. Rather, we control only for NA in order to partial out irrelevant variance overlapping with aversive affect. The above analyses used all participants who completed the baseline session (N = 212), with the exception of correlations with number of sustained cessation periods and proportion of early lapses (only participants who made at least one cessation attempt completed the number of sustained cessation periods item; n=102). Analyses of experimental session data. In the larger study from which this sample was drawn (Leventhal, Waters, et al.

, 2008), a subset of participants did not complete the experimental session (n=50) or did not meet criteria for biochemical confirmation of either smoking in the nondeprived group (CO��9 ppm) or abstinence in the deprived group (CO < 9 ppm; n=42) and were therefore excluded from the analyses of experimental session data. The final sample used in the experimental session analyses consisted of 69 nondeprived smokers and 51 deprived smokers. Participants who did not meet biochemical abstinence criteria were more likely to be male and were heavier, more chronic, and more dependent smokers than those who met biochemical abstinence criteria. These two groups were not significantly different on SHAPS and PANAS-NA scores at baseline (ps>.87).

In addition, the pattern of findings was not substantially altered when both groups were included Cilengitide in the analyses. Therefore, the experimental session analyses presented herein utilize the sample of compliant study completers. To examine whether anhedonia moderated the effects of deprivation on craving, we ran regression models in which the continuous variable of SHAPS scores, Group (deprived vs. nondeprived), and the SHAPS �� Group interaction term were independent variables and craving was the dependent variable. Separate models were run for the dependent variables of QSU-Total, QSU-Factor 1, and QSU-Factor 2.

The lower panel of Figure 2A shows the semiquantitative measurement of band www.selleckchem.com/products/azd9291.html densities. Figure 2 Detection of Ma2 autoantibodies in serum of healthy controls and primary SI-NET patients. Next we confirmed the specificity of Ma2-specific autoantibodies in serum samples from the patients by sequential immunoprecipitation using 35S-methionine-labeled human Ma2 protein generated by in vitro transcription-coupled translation as described in Material and Methods. Ma2-specific autoantibodies were detected in serum samples from primary SI-NET patients expressing high titer of Ma2 autoantibodies (Figure 2B, lanes 6, 7, and 8) but not in serum samples from healthy controls (lanes 3, 4, and 5). Lane 1 shows immune precipitation with a commercial goat anti-human PNMA2 (positive control) and lane 2 shows immunoprecipitation without antibody or serum (negative control).

The lower panel of Figure 2B shows the result of autoradiography of the blot. Recently, we showed that serum antibodies of patients detect Ma2 and faintly Ma1 by using commercial immuno-dot-blot (Figure S1). Progression free survival (PFS) and recurrence free survival (RFS) of primary SI-NET patients, after surgery with curative intent, depend on Ma2 autoantibody titer We have evaluated the clinical data of 36 patients followed up after radical operation of primary tumors with a curative intent. We evaluated Kaplan-Meyer survival curves, followed by a log-rank test to determine whether the curves were different. The hazard ratios were calculated, based on Cox regression function as described in Material and Methods, and found to be 4.

31 (p-value=0.011) for progression free survival (PFS) and 4.24 (p-value=0.012) for recurrence free survival (RFS). The analysis showed that 19 patients with Ma2 autoantibody titer below the cutoff had a longer PFS compared to 17 patients with Ma2 autoantibody titer higher than the cutoff, Figure 3A. The same was true for patients with RFS, Figure 3B. The significance of the analyses is clearly expressed by both p-values=0.006. The median survival time for each group of patients was estimated from the survival curves. It was clearly shorter for patients with Ma2 autoantibody titer higher than the cutoff with an estimated time of about 40 months compared to those with levels below the cutoff with an estimated survival time of about 125 months. The results are summarized in Table 2. Clinical information for patients with Ma2 autoantibodies concentration < cutoff are to the left in Table 2 and clinical information for patients with Ma2 autoantibodies concentration > cutoff are to the right.

874 and P = 0.005 for the HBeAg-positive group and r = 0.732 and P = 0.003 for the HBeAg-negative group), and no correlation was found between http://www.selleckchem.com/products/dorsomorphin-2hcl.html cccDNA and either intrahepatic rcDNA levels (r = 0.595 and P = 0.1 for the HBeAg-positive group and r = 0.336 and P = 0.2 for the HBeAg-negative group) or serum viral titers (r = 0.659 and P = 0.07 for the HBeAg-positive group and r = 0.530 and P = 0.07 for the HBeAg-negative group). In addition, for all groups and subgroups of patients, we evaluated whether serum HBsAg concentrations correlated directly with intrahepatic amounts of HBV DNA. For both HDV-positive and HDV-negative groups of patients and their HBeAg-positive and HBeAg-negative subgroups, we found no correlation between HBsAg concentrations and either intrahepatic HBV DNA or cccDNA amounts.

Comparisions between HBeAg-positive and HBeAg-negative subgroups of HDV-positive and HDV-negative patients are provided as supplimental material. Analysis of HBV BCP and PC region variability. To evaluate whether mutations in the PC and BCP regions of HBV might have any influence on viral replication and transcription, cccDNA molecules from liver biopsy specimens were analyzed by direct sequencing. Of interest, 5 of the 21 (23.8%) HDV-positive and none of the HDV-negative patients (P = 0.01) carried major HBV populations with large deletions (ranging from 45 to 228 bp) in the BCP and PC regions (Fig. (Fig.5).5). The presence of such deletions was associated with lower viremia levels (r = ?0.458; P = 0.04).

However, the previously reported statistical significances obtained by comparing HDV-positive and HDV-negative patients were maintained when these 5 patients were excluded from the analysis. Among the remaining 16 HDV-positive AV-951 patients, 5 (31%) were infected with HBV strains carrying the G1986A nucleotide substitution, introducing a stop codon in the PC region, and 4 of them also had a double BCP mutation at nucleotide positions 1762 and 1764. The presence of PC and/or BCP mutations showed no association with serum or intrahepatic HBV DNA levels. Major HBV populations from 12 (54%) of the 22 HDV-negative patients (2 HBeAg-positive and 10 HBeAg-negative patients) carried mutations in the BCP/PC regions. Notably, the presence of such mutations in the HBeAg-negative subgroup was associated with higher HBV DNA amounts in both serum (r = 0.808; P = 0.003) and the liver (r = 0.866; P = 0.001). FIG. 5. Alignment of HBV DNA nucleotide sequences corresponding to the basal core promoter region and precore region for wild-type (WT) HBV genotype D and the dominant viral populations of 5 HDV-infected patients (2D, 8D, 12D, 13D, and 16D).

There are three isoforms DAPT secretase Notch of TGF-�� (TGF-��1, -��2, and -��3) that are encoded by distinct genes, but have similar biologic actions (1). Of these, TGF-��1 is a major cytokine that contributes to liver fibrosis via activating hepatic stellate cells and increasing the synthesis of extracellular matrix (2). Seven genetic polymorphisms of TGF-��1 have been identified: 3 in the upstream region of the gene at positions -988, -800, and -509; 1 in a nontranslated region at position +72; 2 in the signal peptide sequence region at codon 10 (position +869 C or T) and 25 (position +915 G or C); and 1 in the protein coding region at codon 629 (3). TGF-��1 gene polymorphisms at codon 10 and 25 affect the amounts of TGF-��1 production in vivo and in vitro.

In the lungs, leucine homozygous genotype (L/L, +869 T/T) at codon 10 was associated with increased serum level of TGF-��1 and lung fibrosis (4). Arginine homozygous genotype (+915 G/G) at codon 25 was associated with in vitro increased leukocyte production of TGF-��1 and lung fibrosis (4). In the liver, arginine homozygous genotype at codon 25 was associated with liver fibrosis (5). However, genetic polymorphism at codon 10 showed conflicting results as to which genotype was more fibrogenic in the liver (5-9). These conflicting results could be attributed to the complex pathogenesis and various factors that contribute to liver fibrosis. There has been no genetic polymorphism at codon 25 in Koreans (10). Present study investigated whether the genetic polymorphism at codon 10 is associated with the development of cirrhosis in chronic HBV carriers.

MATERIALS AND METHODS Patients Two hundred and twenty Korean patients with cirrhosis (including HCC with underlying cirrhosis), who had hepatitis B surface antigen (HBsAg, RIA, Abbott Laboratory, Chicago, IL, USA) for over 6 months and no hepatitis C virus antibody (anti-HCV, RIA, General Biologicals Corp, Hsin Chu, Taiwan), were admitted to Gil Hospital, Incheon, Korea from January 2001 to January 2005. Among those, one hundred and twenty-one patients who had alcohol intake of less than 20 g/day and were over 50 yr old were assigned to liver cirrhosis (LC) group. Eighteen patients in LC group were admitted due to non liver related symptoms and diseases. The other 103 patients visited hospital due to liver related symptoms.

Diagnosis of cirrhosis was based on at least 2 of the followings: 1) gastroesophageal varices on endoscopy, 2) cirrhotic surface or regenerating nodules of liver and 3) splenomegaly by radiologic Anacetrapib images (ultrasonography or computed tomography). Eighty-four Korean chronic hepatitis B patients, who had HBsAg for over 6 months, no anti-HCV, no clinical signs of cirrhosis (above criteria), alcohol intake of less than 20 g/day and were over 50 yr old, were admitted to the same hospital during the same periods.
