ABSTRACT

Objective@#To explore the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection who received entecavir alone or in combination with anluohuaxianwan for 78 weeks.@*Methods@#Patients with chronic HBV infection were randomly treated with entecavir alone or in combination with anluohuaxian for 78 weeks. Ishak fibrosis score was used for blind interpretation of liver biopsy specimens. The improvement in liver fibrosis condition before and after the treatment was compared. Student's t test and non-parametric test (Mann-Whitney U-Test and Kruskal-Wallis test) were used to analyze the measurement data. The categorical variables were analyzed by Chi-square test method and Spearman’s rank correlation coefficient was used to test bivariate associations.@*Results@#Liver fibrosis improvement rate after 78 weeks of treatment was 36.53% (80/219) and the progression rate was 23.29% (51/219). The improvement of liver fibrosis was associated to the degree of baseline fibrosis and treatment methods (P < 0.05). The improvement rate of hepatic fibrosis in patients treated with anluohuaxianwan combined with entecavir at baseline F < 3 (54.74%, 52/95) was significantly higher than that in patients treated only with entecavir (33.33%, 16/48), P = 0.016 and the progression rate of hepatic fibrosis (13.68%, 13/95) was lower than that in patients treated alone (18.75%, 9/48), P = 0.466. In patients with baseline F < 3, the proportion of patients with improved and stable liver fibrosis in the combined treatment group (68.1%, 32/47) was higher than that in the treatment group alone (51.7%, 15/29).@*Conclusion@#Combined anluohuaxianwan and entecavir treatment can significantly improve the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection. Furthermore, it has the tendency to improve the stability rate and reduce the rate of progression of liver fibrosis.

ABSTRACT

Objective@#To detect differentially expressed microRNAs in chronic hepatitis B (CHB) before being treated with pegylated interferon (PegIFN) and the relationship between their target genes and HBsAg loss.@*Methods@#Pretreatment differentially expressed microRNAs between different response groups were screened using high throughput microarrays and validated by quantitative reverse-transcription polymerase chain reaction (RT-qPCR). Bioinformatics analysis was performed to determine their target genes potential mechanistic roles.@*Results@#A total of 417 microRNA were differentially expressed between different response groups, among which 342 were up-regulated and 75 were down-regulated. miR-3960, miR-126-3p, miR-23 a-3p and miR-335-5p were verified to be down-regulated by RT-qPCR result in HBsAg loss group. Bioinformatic analysis result show that the relevant pathways of microRNAs include AMPK signal pathway, NOD-like signal pathway, NF-kappa B signal pathway and mTOR signal pathway.@*Conclusions@#HBsAg loss is probably achieved as the result of genes expression regulated in association with immune response, further enhance the immune response of HBV elimination and acquire HBsAg loss.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the clinical effect of L-ornithine L-aspartate (LOLA) granules in treating chronic liver disease in patients with high-level serum gamma-glutamyltransferase (G-GT) using a 24-week treatment course.</p><p><b>METHODS</b>Two-hundred patients with chronic liver disease and above normal G-GT were given a 12-week course of LOLA granules (9 g/d) and then classified into the following three groups according to the change in serum Gamma-GT:group I:patients with Gamma-GT level returned to normal;group II:patients with serum Gamma-GT level that was reduced during the treatment; group III:patients with serum Gamma-GT level that did not decrease or that increased to a higher level than at start of treatment.After the 12-week treatment course, the patients in group I were divided into three subgroups for receipt of a control drug (compound glycyrrhizin, 50mg/d) or an additional 12-week course of Gamma-GT at a reduced dose (LOLA granules 3 g/d) or at the original dose; groups II and III were maintained on the initial dose for an additional 12 weeks.The groups were reassessed at the end of the second 12-week course (at the end of week 24 of the study's observation period).Count data were compared using the x2 test and measurement data were compared using the t-test.</p><p><b>RESULTS</b>In group I, the serum Gamma-GT level was 90.9% at the end of the first 12-week course and dropped to a mean level of 52.2% for both of the subgroups that received the reduced and original dose after the additional 12 weeks of LOLA granules treatment; the difference from week 12 to week 24 was significant (x2=8.213, P less than 0.05).The 24-week change in serum Gamma-GT levels for the group I reduced and original dose subgroups vs.the control subgroup were also significantly different from those seen in groups II and III (P less than 0.05).The percentage of patients in group I who achieved normal level serum Gamma-GT after 24 weeks of treatment (78.6%) was significantly higher than that for the control group (vs.55.0%, x2=11.452, P less than 0.05).When the patients in group 1 who had received the 12 additional weeks of LOLA granules treatment were measured again at two weeks after the treatments had been discontinued (end of week 26), the percentage of patients with normal serum Gamma-GT level was 92.7%, with only three cases showing obviously abnormal levels; in contrast, the group I patients in the control group of the second 12-week study period had on 66.7% of patients with normal-level serum Gamma-GT.The difference in change between the treated groups (both reduced and original dose) and the control group was significant (x2=14.964, P less than 0.05).</p><p><b>CONCLUSION</b>Patients whose serumGamma-GT levels returned to normal after receipt of LOLA granules for 12 weeks benefitted from an additional 12 weeks of consolidation treatment, and those given the treatment at the original dose benefitted most.Compared with the compound glycyrrhizin, LOLA granules provided a better maintenance of resolved Gamma-GT level.Therefore, the effect of LOLA appears to be reliable and stable as well as safe for clinical use.</p>

ABSTRACT

Objective To study the function of 4 different haplotypes cDNA which are constructed by two non-homonymy single nueleotide polymorphism (SNP) sites C19170G (Leu45Val) and C30799G (Ala500Gly) in the coding region of human CⅡTA gene. Methods HeLa cells were transfeeted with eu-karyotic expression vectors containing four different haplotypes cDNA. C Ⅱ TA mRNA and HLA classⅡanti-gen (HLA-DR, DP, DQ) were respectively detected by RT-PCR and indirect cell immunofluoreseence tech-nique in the untransfected and transfeeted with four eukaryotic expression vectors and empty vectors HeLa cells. The quantity of HLA classⅡ antigen were analyzed by flow eytometry. Results No expression of CⅡTA mRNA and HLA class Ⅱ antigen were observed on original HeLa cells and empty vector transfected cells. CⅡTA mRNA expression was emerged, and the expression of HLA class Ⅱ antigen were observed in the HeLa cells transfected with eukaryotic expression vectors containing four different haplotypes cDNA. And there were not significantly different with the levels of HLA class Ⅱ antigen expression among HeLa cells transfected with eukaryotic expression vectors containing four different haplotypes cDNA ( P > 0.05 ). Con-dusion The SNP of Chinese at the sites C19170G(Leu45Val) and C30799G(Ala500Gly) in the coding site of C Ⅱ TA gene did not influence capability of CⅡTA trans-aetivating HLA class Ⅱgene expression.

ABSTRACT

Objective To investigate the relationship between the non-homonymy single nucleotide polymorphism(SNP)of C19170G,C30799G in the coding area of class Ⅱ transaetivator(CII TA)and the different clinical phenotypes of chronic hepatitis B virus(HBV)infection.Methods Six hundred and twenty-seven patients with chronic HBV infection and 101 healthy blood donors were enrolled in this study.Genotyping of C19170G,C30799G in C Ⅱ TA gene coding region were done by sequence-specific primer polymerase chain reaction(PCR-SSP).Hardy-Weinberg balance of the genotypes was analyzed using chi-square test.Differences between two sets were tested by contingency table chi-square test and unconditional Logistic regression was performed. Results The frequencies of G allele and GG+GC genetypes at 19170 site were significantly higher in patients with liver cirrhosis than those with non-progressive liver diseases(X2=7.128,P=0.008;X2=6.404,P=0.011,respectively).There were significantly differences of the allele frequencies between patients with liver cirrhosis and non-progressive liver diseases(OR:0.742,95%CI:0.552~0.998,P=0.048),and the main differences were observed in G dominant model(OR:0.581,95% CI:0.353~0.954,P=0.032).The frequencies of C allele and CC genotype at 30799 site were significantly higher in patients with hepatocellular carcinoma than those in patients with liver cirrhosis(X2=4.861,P=0.027;X2=4.993,P=0.025).There were significant differences of the genotype frequencies at 30799 site between patients with liver cirrhosis and hepatocellular carcinoma(OR:0.557,95% CI:0.334~0.930,P=0.025),and the differences were mainly observed in C recessive model(OR:0.491,95% CI:0.269~0.898,P=0.021).Conclusions The polymorphisms at 19170 site are associated with liver cirrhosis in chronic HBV infection,and the G allele carriers are prone to progress into liver cirrhosis.The polymorphisms at 30799 site are associated with hepatocellular carcinoma in chronic HBV infection,and CC genotype carriers are prone to progress into hepatocellular carcinoma.

ABSTRACT

Objective To study the effects of IFN ?,TNF ?,IL 1 and dexamethasone on the expression of intercellular adhesion molecule 1(ICAM 1) of primary cultured human hepatocyte. Methods ICAM 1 expression of primary cultured human hepatocyte was induced in vitro by IFN ?,TNF ? and IL 1, measuring by cellular enzyme linked immunosorbent assay(ELISA). The effect of dexamethasone on human hepatocyte ICAM 1 expression was observed by adding dexamethasone into the cultured human hepatocytes prior to cytokine stimulation. Results The levels of ICAM 1 expression were significantly lower in unstimulated human hepatocytes than in human hepatocytes induced by IFN ?,TNF ? and IL 1. There were relations among the levels of ICAM 1 expression and cytokine concentration as well as induced period of time. Dexamethasone could partly inhibit the ICAM 1 expression on human hepatocytes induced by TNF ?,IL 1 and IFN ?.The inhibition rates were 40.3%?5.9%,38.1%?4.8%, and 37.6%?6.7%, respectively.Conclusions Enhanced ICAM 1 expression of primary cultured human hepatocyte may be induced in vitro by IFN ?,TNF ? and IL 1, which may be partly inhibited by dexamethasone.
