These results imply that LHBs, in association with HIF-1α, induces MDR1 overexpression, which may contribute to the pathogenic changes in CHB infection.
Taken together, these results indicate that miR-194 plays a crucial role in hepatocyte proliferation and liver regeneration by targeting ACVR2B and may represent a novel therapeutic target for the treatment of CHB-related liver damage.
TACE promoter methylation frequency in HBeAg-positive CHB (58/80, 72.5%) was significantly lower than that in HBeAg-negative CHB (72/80, 90%; χ (2) = 8.041, P < 0.01) and HCs (χ (2) = 8.438, P < 0.01).
The results suggested that increased ADAMTS13: AC after 1 year ETV treatment was associated with a higher seroconversion, and could be used surrogate of HBeAg SC in CHB patients during 5-year ETV treatment.
Plasma PACAP-38 levels were measured using competitive radio-immune analysis (RIA) in 25 CHB patients before and after completion of a 52-week lamivudine treatment period and in 22 healthy blood donors.
Adiponectin (mug/mL) and TNF-alpha (pg/mL) determinations by enzyme-linked immunosorbent assay (ELISA) in serial samples (before, the middle, the end, and 6 months after the end of treatment) from 83 CHC and 59 chronic hepatitis B (CHB) patients.
Use of the ADO II in non-ductal positions can be achieved with high success and low complication rates, especially CHB; its use is also associated with significantly reduced procedure time and device cost.
Evaluation of the CDO1 promoter methylation status in serum, in combination with AFP (> 20 ng/ml), significantly improved the diagnostic value, with sensitivity and specificity of 82.9% and 75.4%, respectively in distinguishing HCC from LC and CHB.
The area under the curve (AUC) for <i>RASSF1A</i> methylation (0.718) was better than the corresponding AUC for AFP (0.609) in distinguishing HCC from CHB.
A combination of PIVKA-II and AFP demonstrated better diagnostic accuracy in differentiating patients with HBV-HCC from patients with CHB or HBV-LC than AFP or PIVKA-II alone [area under the curve (AUC), 0.922 (95% CI, 0.908-0.935), sensitivity 88.3% and specificity 85.1% for the training cohort; 0.902 (95% CI, 0.875-0.929), 87.8%, and 81.0%, respectively, for the validation cohort].
The UBE2Q1 gene methylation status combined with alpha fetoprotein using cut-off points of 20, 200 and 400 ng/ml showed sensitivity and specificity values of 58.8% and 75.0%, 53.8% and 87.5%, and 37.5% and 88.7%, respectively, and yielded a significantly increased area under the ROC curve (0.720, 0.760 and 0.694, respectively) for discriminating HCC from LC and CHB.
Our findings strongly suggested the combination of serum TGR5 promoter methylation and AFP enhanced the diagnostic value of AFP alone in discriminating HCC from CHB patients.
These results suggested that combined quantitative measurement of serum IGFBP7 promoter methylation could enhance the diagnostic ability of AFP in distinguishing hepatitis B virus-associated HCC from CHB.
Besides detecting patients with early stage or small tumours (eg, ≤2.0 cm) from non-HCC, the 5hmC model showed high capacity for distinguishing early HCC from high risk subjects with CHB or LC history (validation set: AUC=84.6%; (95% CI 80.6% to 88.7%)), also significantly outperforming AFP.
When AFP levels were used in combination with the triplex miRNA panel, the diagnostic performance was significantly improved in discriminating HCC from the other groups (LC, AUC = 0.887; CHB, AUC = 0.948; CHB+LC, AUC = 0.887).
A nomogram composed of age, sex, presence of cirrhosis, serum AFP levels and US findings better predicted the presence of HCC compared to US-only screening in CHB on surveillance.
The expression of AIM2 mRNA was significantly negatively correlated with serum hepatitis B virus (HBV) load, HBeAg, and significantly positively correlated with IL-1β and IL-18 in AHB patients and CHB patients with immune clearance, which suggests that AIM2 expression is correlated with the immune clearance of HBV in the host.
