Objective:b> To explore the role of transient elastography technology in the assessment of disease staging and treatment in patients with chronic hepatitis B virus (HBV) infection. Methods:b> Patients who were clinically diagnosed with chronic HBV infection at Beijing Tsinghua Changgung Hospital from January 2018 to December 2021 was collected. Liver stiffness measurement (LSM) examination was performed more than once by transient elastography. The count data were expressed as cases (%) and the χ (2) test was made. Fisher's exact test was used with theoretical frequency less than 5. The measurement data between two groups was compared by t-test. Multiple groups were compared with an analysis of variance. Results:b> 1 055 patients were included in this study, including 669 (63.4%) males and 386 (36.6%) females. 757 (71.8%) patients were untreated. Among the untreated patients, the LSM value in the immune clearance (10.2 ± 3.8) kPa (187 cases, 40.4%), and the reactivation stages (9.1 ± 3.4) kPa (114 cases, 24.6%) was significantly higher than that in the immune tolerance (8.7 ± 3.6) kPa (78 cases, 16.8%) and immune control stages (8.4 ± 3.5) KPa (84 cases, 18.1%), and the difference between the four groups was statistically significant (F = 5.31 and P = 0.03). With ALT (male: 30 U/L, female: 19 U/L) as defined the normal value, the LSM value in the immune tolerance and the immune control stages were (5.8 ± 0.9) kPa and (7.1 ± 2.5) kPa, respectively, which were significantly lower than those of patients in the immune tolerance and immune control stages, and the difference was statistically significant (P < 0.01). There were 294 (38.8%) patients with uncertain period, excluding patients with fatty liver. Patients with uncertain periods were divided into four gray zone (GZ) groups: immune tolerance stage: LSM (5.1 ± 1.3) kPa was significantly lower than GZ-A (6.5 ± 2.4) kPa, t = 2.06, P = 0.03, and the difference was statistically significant; immune control stage: LSM was (5.6 ± 1.5) kPa, which was also lower than GZ-C (6.8 ± 1.3) kPa, t = 3.08, P = 0.02, and the difference was statistically significant; immune clearance stage: LSM > 8.0 kPa. LSM values showed a year-by-year reduction in patients with expanded indications who started antiviral treatment and were followed up for three years. Conclusion:b> The LSM value is significantly lower after the decrease of the defined high-normal ALT value in patients with the immune tolerance and immune control stages of chronic HBV infection. The LSM values of GZ-A and GZ-C in the uncertain periods of chronic HBV infection are higher than those of patients in the immune tolerance and immune control stages.

<b>OBJECTIVEb>To investigate the impact of hepatic steatosis on virologic response to treatment with pegylated interferon-alpha-2a (PEG-IFNα-2a) in chronic hepatitis B (CHB) patients.

<b>METHODSb>We retrospectively analyzed 50 biopsy-proven cases of CHB in patients who had been administered a 48-week course of PEG-IFNα-2a in our hospital between 2005 and 2009. The patients were stratified according to presence of steatosis confirmed by pathological findings, with 28 in the non-steatosis group and 22 in the steatosis grouP(21 with mild steatosis,and 1 with moderate steatosis).

<b>RESULTSb>from blood routine test,hepatic and renal function tests, fasting blood glucose test, thyroid function test and blood lipid test were collected for analysis, as were results from hepatitis B viral load test and detection of hepatitis B virus (HBV) markers and autoantibodies. The efficacy of antiviral treatment and side effects were compared between the stratified groups by statistically comparing the results from before and after the 48 weeks of treatment.

<b>RESULTSb>At the end of treatment, the non-steatosis group had 42.9% of patients with undetectable HBV-DNA ( less than 500 copies/ml), a hepatitis B e antigen (HBeAg) seroconversion rate of 31.6% and a complete response rate of 39.3%. The steatosis group had a lower rate of patients with undetectable HBV-DNA (40.9%) and higher rates of HBeAg seroconversion (33.3%) and complete response (40.9%), but none of the differences reached the threshold for statistical significance (x2=0.012, 0.019, 0.014 and P=0.560,0.600,0.568 respectively). Both groups showed significant increases in triglyceride levels after treatment (steatosis group:t =-2.164, P=0.040; non-steatosis group:t =-2.863, P=0.009), and there was a significant difference between the two groups (t=2.41, P=0.020).

<b>CONCLUSIONb>Our study did not show that mild hepatic steatosis affected the efficiency of a 48-week course of PEG-IFNα-2a treatment for patients with CHB.

<b>OBJECTIVEb>To analyze the development of liver damage and reactivation of hepatitis B virus (HBV) during the treatment of extremely severe burn injury in HBsAg positive patients, in order to provide reference for prevention and treatment of liver damage in patients with HBV infection after extremely severe burn.

<b>METHODSb>Medical records of 54 HBsAg positive patients after extremely severe burn injury admitted from January 2004 to December 2014 were retrospectively analyzed. Development of liver damage and HBV reactivation of these patients during the treatment were analyzed according to the classification of their gender, results of hepatitis B e antigen (HBeAg) and HBV DNA examinations on admission, and development of sepsis in the process of treatment. Data were processed with chi-square test.

<b>RESULTSb>(1) The incidence of liver damage in the process of treatment of these patients was 85.2% (46/54). Among all the patients, the proportion of liver damage was 35/38 in male, which was significantly higher than that in female (11/16, χ² = 4.867, P<0.05). Liver damage was found in all of 26 patients who were HBeAg positive on admission, 34 patients who were HBV DNA positive on admission, and 36 patients who developed sepsis in the process of treatment; the proportions were significantly higher than those in patients who were HBeAg negative on admission (20/28), patients who were HBV DNA negative on admission (12/20), and patients who did not develop sepsis in the process of treatment (10/18), with χ² values respectively 11.801, 18.384, and 20.574, P values below 0.01. (2) The incidence of HBV reactivation in these patients was 29.6% (16/54). Among all the patients, the proportion of HBV reactivation was 13/38 in male and 3/16 in female, with no statistically significant difference between them (χ² = 0.656, P>0.05). The proportions of HBV reactivation in patients who were HBeAg positive on admission, patients who were HBV DNA positive on admission, and patients who developed sepsis in the process of treatment were respectively 13/26, 16/34, and 15/36, and they were significantly higher than those in patients who were HBeAg negative on admission (3/28), patients who were HBV DNA negative on admission (0/20), and patients who did not develop sepsis in the process of treatment (1/18), with χ² values respectively 9.979, 18.615, and 5.873, P<0.05 or P<0.01.

<b>CONCLUSIONSb>Patients who are HBsAg positive, HBeAg positive, HBV DNA positive on admission, and develop sepsis in the process of treatment of extremely severe burn injury are more likely to develop liver damage and HBV reactivation. It is necessary to dynamically monitor the changes in HBV DNA and liver function, in order to identity the reactivation of virus.

<b>OBJECTIVEb>To explore the effects of Xinganbao Capsule (Cordyceps Sinensis) on the chronic hepatitis B liver fibrosis.

<b>METHODSb>Sixty patients with chronic hepatitis B were randomly assigned to the trail group (40 cases) and the control group (20 cases). The trail group was treated with Xinganbao Capsule, 8 capsules each time, three times a day. The control group was given Heluo Shugan Tablet, 5 pills each time, thrice daily. Six months consisted of one therapeutic course. The liver function, four indicators of serum fibrosis, liver histology, and other items were detected.

<b>RESULTSb>Xinganbao Capsule could reduce serum ALT and AST levels, serum HA, PC-III and LN levels (all P<0.05), showing statistical difference when compared with before treatment. The HA and LN levels decreased more significantly in the control group when compared with before treatment (P<0.05). Totally 21 patients (53% of the recruited cases) in the trial group completed the liver biopsy twice. After treated with Xinganbao Capsule, 81% patients (17/21) had decreased liver inflammation 1 grade or more, 52% patients (11/21) had decreased fibrosis staging one or more, and 33% (7/21) patients had no change in fibrosis.

<b>CONCLUSIONb>Xinganbao Capsule could improve the liver function, reduce liver inflammation, and fight against hepatic fibrosis.

<b>OBJECTIVEb>To establish non-invasive predictors of antiviral therapy for chronic HBV carriers.

<b>METHODSb>Liver biopsies were performed in 139 chronic HBV carriers. Seventeen of them were histopathologically graded as G > or =2 or S > or =3, being considered in need of antiviral therapy. The other 122 subjects with grades G < 2 and S < 3 were not applicable for antiviral therapy. Independent predictors were analyzed using logistic regression (Backward). The covariates included age, gender, duration of HBV infection, family history of hepatitis B, HBeAg positivity, quantitive HBeAg, level of LN, PCIII, HA, CIV and gamma-globin, low white blood cell count, spleen measurement and HBV load. ROC curve was used to define the diagnostic critical value.

<b>RESULTSb>Logistic regression analysis showed that PCIII, but not other factors, was related to antiviral therapy in these HBV carriers (OR = 1.122). When the diagnostic critical value was 85.02 ng/ml, 100.79 ng/ml and 105.50 ng/ml, its sensitivity was 80.0%, 67.3% and 54.8%, respectively; its specificity was 52.0%, 70.6% and 84.2%, respectively. The area under ROC curve was 70.8%.

<b>CONCLUSIONb>PCIII might be a reference index for predicting antiviral therapy in chronic HBV carriers, but liver biopsy is still a non-substutiable reference index.

BACKGROUND/AIMS: Liver stiffness (LS) as assessed by transient elastography (TE) can change longitudinally in patients with chronic hepatitis B (CHB). The aim of this study was to identify the factors that improve LS. METHODS: Between April 2007 and December 2012, 151 patients with CHB who underwent two TE procedures with an interval of about 2 years were enrolled. Ninety-six of the 151 patients were treated with nucleos(t)ide analogues [the antiviral therapy (+) group], while the remaining 55 patients were not [the antiviral therapy (-) group]. The two groups of patients were stratified according to whether they exhibited an improvement or a deterioration in LS during the study period (defined as an LS change of < or =0 or >0 kPa, respectively, over a 1-year period), and their data were compared. RESULTS: No differences were observed between the antiviral therapy (+) and (-) groups with respect to either their clinical characteristics or their initial LS. The observed LS improvement was significantly greater in the antiviral therapy (+) group than in the antiviral therapy (-) group (-3.0 vs. 0.98 kPa, P=0.011). In the antiviral therapy (+) group, the initial LS was higher in the LS improvement group (n=63) than in the LS deterioration group (n=33; 7.9 vs. 4.8 kPa, P<0.001). However, there were no differences in any other clinical characteristic. In the antiviral therapy (-) group, the initial LS was also higher in the LS improvement group (n=29) than in the LS deterioration group (n=26; 8.3 vs. 6.5 kPa, P=0.021), with no differences in any other clinical characteristic. CONCLUSIONS: A higher initial LS was the only factor associated with LS improvement in patients with CHB in this study.

<b>OBJECTIVEb>To detect the level of serum and liver tissue TGF-beta1 in patients with chronic hepatitis B, to study their relation to liver fibrosis and gain the evidence for diagnosis of liver fibrosis.

<b>METHODSb>The liver fibrosis grades (S0-S4) of 131 cases with chronic HBV infection were diagnosed after liver biopsy. Serum TGF-beta1 was detected by enzyme-linked immunosorbent assay, and the semiquantitative analysis was applied after detecting the expression of TGF-beta1 in liver tissue with immunohistochemistry. Their relations to liver fibrosis were analyzed.

<b>RESULTSb>Serum and tissue level of TGF-beta1 increased significantly with the development of fibrosis, and the same result was obtained between themselves (P < 0.01). There was very significant difference for serum level of TGF-beta1 among the groups with different fibrosis grades (P < 0.01). Serum levels of TGF-beta1 were decreased significantly comparing the Group S0 or S1 to S4 (P < 0.005). There were significant difference for serum level of TGF-beta1 among S0 and the others (P < 0.005). And there was significant difference between S1 and S3 (P < 0.005). The expression level of TGF-beta1 in liver tissue has no significant difference between group S3 and S4 (P > 0.05). However, the differences were significantly among the other comparisons (P < 0.01).

<b>CONCLUSIONb>There is close relation between the level of TGF-beta1 and the different liver fibrosis grades due to chronic hepatitis B. The serum level of TGF-beta1 is a potential noninvasive maker for diagnosis of liver fibrosis.

<b>OBJECTIVESb>To probe into the initiative factors of the damage sensitive stage of hepatocytes induced by interferon in patients with chronic hepatitis B (CHB).

<b>METHODSb>Forty-four CHB patients with positive HBeAg and HBV DNA were treated with interferon. Serum ALT and viral markers levels of HBsAg, HBeAg, anti-HBc and HBV DNA were examined regularly. Liver biopsy was carried out just before the treatment.

<b>RESULTSb>The rate of HBeAg seroconversion was 75% at the sixth month, and 68.2% after one year of follow up. The rate of damage sensitive stage of hepatocytes was 47.7%. The average onset time was (3.14+-1.49) weeks after the treatment, and lasted for (8.24+-3.52) weeks. The ALT level raised (1.73+-1.13) times. The occurrence of damage sensitive stage of hepatocytes was indicator for good curative effect (Fisher exact probability, P=0.028). Damage sensitive stage of hepatocytes was more often developed in patients with moderate inflammation, overexpression of HBcAg in liver and higher level of HBeAg in blood stream before treatment. HBeAg and anti-HBc levels in peripheral blood decreased in the onset period of damage sensitive stage of hepatocytes.

<b>CONCLUSIONSb>The initiative factors of the damage sensitive stage of hepatocytes may be: HBeAg decreasing in peripheral blood induced by interferon may dismiss immune lutation of HBeAg and anti-HBc to cytotoxic T lymphocyte (CTL), which recognize HBcAg as target, thus activates the cytotoxicity of HBV-infected hepatocytes mediated by CTL.
