Abstract:

In China universal vaccination program against hepatitis B virus( HBV) in newborns has led to a dramatic decline in HBs Ag prevalence from 9. 75% in 1992 to 7. 18% in 2006. However,it is estimated that there are still around 90 million patients with chronic HBV infection,including 20- 30 million with chronic hepatitis B( CHB). As recommended therapies,interferons and nucleos( t) ide analogues can effectively suppress HBV replication and thereby halt the progression of liver disease. Unfortunately,the current standard of care could not cure CHB in most cases. Developing direct antiviral agents targeting the specific steps of HBV life cycle or immunotherapy against the key steps of immune response to HBV infection will ultimately enable us to cure CHB. Chinese hepatologists have published more and more papers on HBV prevention and management,with the aim of optimizing current modalities and exploring new therapies. Adopting the public health policy to improve the accessibility and affordability of preventive and therapeutic drugs and increase the coverage of vaccination and standardized treatment is the most effective means to reduce the enormous health and socioeconomic burden of HBV- related diseases.

2015, 31(4): 495-499. DOI: 10.3969/j.issn.1001-5256.2015.04.005
Abstract:
Currently,there are two categories of antiviral drugs used for chronic hepatitis B( CHB) : interferons( IFNs) and nucleos( t) ide analogues( NAs). IFNs showed lower efficacy and more adverse effects,although they achieved some anti- HBV results. NAs showed stronger antiviral activity and a lower incidence rate of adverse effects; however,there are also some problems,such as high risk of relapse after the NAs are discontinued and increased rate of drug resistance with a longer course of treatment. Therefore,it is very important for clinicians to investigate the optimal therapy against HBV to further improve efficacy and safety in the treatment of CHB. In this paper,the research on combination therapy and sequential therapy against HBV is reviewed,in the hope that clinicians may have a deeper knowledge of combination therapy and sequential therapy against HBV,so as to provide more choices for antiviral therapy of CHB patients.

Shen Yao, Zhang XiaoHui, Chen Yu
2015, 31(4): 500-504. DOI: 10.3969/j.issn.1001-5256.2015.04.006
Abstract:
Mother- to- child transmission( MTCT) is an important way of hepatitis B virus( HBV) transmission. Blocking the HBV MTCT has a great significance for the prevention and treatment of hepatitis B. This article reviews the current blocking strategies implemented in the antepartum,peripartum,and postpartum stages,and summarizes the controversies existing in the blocking strategies in different stages. The significance of HBV occult infection and germ cell transmission in the HBV MTCT is analyzed. The results indicate that the current strategies for the prevention of hepatitis B MTCT need further improvement. Attentions should be focused on HBV occult infection and germ cell transmission.

Significance of changes in hepatic histology from patients with HBe Ag( + ) or HBe Ag(-) chronic hepatitis B and normal or mildly elevated alanine aminotransferase
Lan Lin, Kong Yin, Zhang LingYi
2015, 31(4): 510-513. DOI: 10.3969/j.issn.1001-5256.2015.04.008
Abstract:
Alanine aminotransferase( ALT) abnormality is an indicator of the degree of liver inflammation caused by immune activation in patients with chronic hepatitis B( CHB). However,approximately half of the CHB patients with normal or mildly elevated ALT levels have concealed significant changes in hepatic histology. CHB patients with normal or mildly elevated ALT levels may have significant histopathological changes in hepatic tissues,and those changes vary between HBe Ag( +) and HBe Ag(-) CHB patients. Attention and investigation on the clinical management of CHB patients with normal or mildly elevated ALT levels may have great significance in grasping the right treatment opportunity and reducing the risk of liver cirrhosis.

Zhang XinXin, Wang MingJie
2015, 31(4): 514-519. DOI: 10.3969/j.issn.1001-5256.2015.04.009
Abstract:
The high mutation rate during hepatitis B virus( HBV) replication leads to HBV quasispecies. The study of HBV quasispecies has an important significance for the hepatitis B pathogenesis,prognosis,and outcome prediction. Recently,the next- generation sequencing( NGS) is extensively used in many biological and medical fields due to its high throughput,ultra- deep coverage,and high sensitivity,which also brings new strategies to HBV quasispecies studies. This article describes the working principles and features of several commonly used NGS technologies,reviews the application of NGS technologies in HBV quasispecies detection in recent years,and particularly discusses the variations in different regions of HBV genome and the population characteristics of HBV quasispecies. For now,NGS technologies used in HBV variation detection mainly presents the advantages of high sensitivity and high throughput. However,how to lower the cost,increase the accuracy of sequencing,and standardize the procedure of massive sequencing data management and personalized analysis are still challenging problems. The issue about NGS that matters at present and urgently needs to be solved is how to overcome its limitations,and then put it into HBV- related studies and ultimately clinical application.

Zhang JiWang, Tang ZhiGui, Yuan YongQiang
2015, 31(4): 520-522. DOI: 10.3969/j.issn.1001-5256.2015.04.010
Abstract:
Objective To investigate the serum levels of liver function- related proteins( cholinesterase,Ch E; album,Alb,prealbumin,PA; transferrin,TRF; ferritin,FRT; C- reactive protein,CRP; and ceruloplasmin,CER) and assess their clinical diagnostic significance for chronic hepatitis B virus( HBV) carriers. Methods The study selected 86 HBV carriers who were diagnosed in the Affiliated Yong-Chuan Hospital of Chongqing Medical University from January 2012 to July 2014( the observation group). Additionally,102 healthy individuals who underwent physical examination in the hospital were selected( the control group). Biochemical indices including serum Ch E,Alb,PA,FRT,TRF,CRP,and CER levels were measured in both groups. Liver biopsy was performed in part of the observation group. Group comparison of continuous data was performed using the independent- samples t test. Results Serum CER levels in the observation and control groups were( 0. 20 ± 0. 04) g / L vs( 0. 29 ± 0. 06) g / L,showing a statistically significant difference( t = 2. 03,P = 0. 03). No significant differences occurred in the rest of biochemical indices between groups( P > 0. 05 for all). Serum CER levels were significantly decreased in patients with higher severity of liver inflammation and fibrosis [( 0. 23 ± 0. 01) g / L vs( 0. 18 ± 0. 02) g / L,t =- 2. 6,P = 0. 01;( 0. 22 ± 0. 02) g/L vs( 0. 17 ± 0. 04) g/L,t =- 3. 2,P = 0. 004]. Conclusion The change in serum CER level can reflect the severity of liver inflammation and fibrosis in the early stage. Thus,serum CER level may become an important index for early diagnosis and treatment of HBV carriers.

Xia ShuLin, He XiaoFeng
2015, 31(4): 523-525. DOI: 10.3969/j.issn.1001-5256.2015.04.011
Abstract:
Objective To evaluate the efficacy of entecavir treatment up to 96 weeks for patients with chronic hepatitis B( CHB). Methods The study recruited 62 CHB patients who were admitted to or hospitalized at the Taixing People' s Hospital from July 2011 to July 2014.The patients were treated with entecavir( 0. 5 mg / d) for 96 weeks of antiviral therapy. All the patients were divided into HBe Ag- positive( n = 43) and HBe Ag- negative groups( n = 19). The HBV DNA load was higher than 106 copies / ml in 38 patients and lower than 106 copies / ml in 24 patients. The efficacy of entecavir in the two groups was compared at 24,48,and 96 weeks of treatment. Between- group comparison of categorical data was performed by χ2test. Results At 24,48,and 96 weeks of treatment,the HBe Ag- positive group had a significantly lower HBV DNA clearance rate than the HBe Ag- negative group( 34. 88% vs 78. 95%,P = 0. 003; 65. 12% vs 89. 47%,P = 0. 047; 74. 42% vs 100%,P = 0. 038); there was no significant difference in alanine aminotransferase( ALT) normalization rate between the two groups( P = 0. 102,0. 779,and 0. 638). Patients with a HBV DNA load of > 106 copies / ml had a significantly lower HBV DNA clearance rate than those with a HBV DNA load of < 106 copies / ml at 24,48,and 96 weeks of treatment( 34. 21% vs 70. 83%,P = 0. 005; 57. 89% vs 95. 83%,P = 0. 001; 76. 32% vs 95. 83%,P = 0. 002); there was no significant difference in ALT normalization rate between the two groups( P = 0. 940,0. 150,and 0. 280). Conclusion Entecavir has a high antiviral activity in the treatment of CHB,which can suppress HBV replication and concurrently improve liver function.

Li HuoYan, Yang ZhaoHui, Ma LiLi, Ma Long
2015, 31(4): 526-529. DOI: 10.3969/j.issn.1001-5256.2015.04.012
Abstract:
Objective To evaluate the clinical efficacy and safety of telbivudine( TLD) and interferon( IFN) α in the treatment of HBe Ag-positive chronic hepatitis B( CHB). Methods A total of 84 CHB patients who were admitted to Xiamen Municipal Third Hospital Affiliated to Fujian University of Traditional Chinese Medicine from April 2011 to October 2013 were equally and randomly divided into TLD group( treated with TLD) and IFNα group( treated with IFNα). Serum alanine aminotransferase( ALT) normalization rate,HBV DNA clearance rate,HBe Ag seroconversion rate,the quantity of HBe Ag,and the safety of the two drugs were determined at weeks 12,24,and 48 of treatment. Comparison of continuous data between the two groups was made by independent- samples t test,and comparison of categorical data was made by chi- square test. Results There were no significant differences in serum ALT normalization rate between the two groups at weeks 12,24,and 48 of treatment( P > 0. 05),and there were no significant differences in HBe Ag seroconversion rate between the two groups at weeks 12 and 24 of treatment( P > 0. 05). The TLD group had a significantly lower HBe Ag seroconversion rate than the IFNαgroup at weeks 48 of treatment( χ2= 4. 42,P = 0. 04). And the TLD group had a significantly higher HBV DNA clearance rate than the IFNα group at weeks 12( χ2= 4. 53,P = 0. 02),24( χ2= 7. 16,P = 0. 01),and 48 of treatment( χ2= 5. 19,P = 0. 03). The IFNα group had a significantly lower quantity of HBe Ag than the TLD group at week 48 of treatment( t = 2. 45,P = 0. 02). No obvious adverse reactions were found in either group. Conclusion For patients with HBe Ag- positive CHB,TLD has a strong antiviral effect and leads to a higher HBV DNA clearance rate than IFN at weeks 12,24,and 48 of treatment,but it causes a lower HBe Ag seroconversion rate than IFN at week48 of treatment. Both drugs have good safety and tolerability.

Wang ShaoYang, Lin TaoFa, Liu HaiZhou, Ma WeiMin, Xie ZhiHong
2015, 31(4): 530-533. DOI: 10.3969/j.issn.1001-5256.2015.04.013
Abstract:
Objective To evaluate the safety and efficacy of autologous cytokine- induced killer( CIK) cells in the treatment of patients with chronic hepatitis B( CHB),and to investigate a new therapeutic strategy for CHB. Methods Peripheral blood mononuclear cells were isolated from 84 patients with CHB,and then induced to CIK cells in vitro with cytokines such as interferon- γ,interleukin- 2,and monoclonal antibody against CD3. The autologous CIK cells obtained were infused back into the individual patient. Liver function parameters,serum markers,and HBV DNA levels were evaluated before treatment and at 12,24,and 48 weeks after treatment. Fifty patients who received entecavir( ETV) treatment were used as controls. Comparison was made between HBe Ag- positive patients and HBe Ag- negative patients.Adverse reactions and kidney function were evaluated. Comparison of continuous data between the two groups was made by t test,and comparison of categorical data was made by chi- square test. Results The alanine aminotransferase( ALT) levels in both HBe Ag- positive patients and HBe Ag- negative patients in the treatment group decreased as the observation time went on. HBe Ag- positive patients in the treatment group had significant lower ALT levels than those in the control group at 12 and 24 weeks after treatment( t = 5. 03,P < 0. 01; t =4. 72,P < 0. 01). The treatment group had higher HBe Ag clearance rate and seroconversion rate than the control group at each time point.Particularly,there were significant differences in HBe Ag clearance rates at 24 and 48 weeks after treatment between the two groups( χ2=6. 85,P < 0. 05; χ2= 4. 83,P < 0. 05). Both HBe Ag- positive patients and HBe Ag- negative patients in the treatment group had higher HBV DNA levels and lower incidence rates of undetectable HBV DNA level than those in the control group. However,as the observation time went on,the HBV DNA copy level gradually decreased,and the HBV DNA clearance rate gradually increased in the treatment group. Conclusion The therapy with autologous CIK cells is safe and effective in patients with CHB during 48 weeks after treatment. In spite of a lower HBV DNA clearance rate,this therapy results in higher HBe Ag clearance rate and seroconversion rate than ETV therapy as the observation time goes on,which suggests a probably sustainable immune response after treatment with autologous CIK cells.

Wang Fei, Xu AiLing, Xin XiaXia, Yuan Hong, Xiong JingJing, Zhang Qi, Wang Chen
2015, 31(4): 534-536. DOI: 10.3969/j.issn.1001-5256.2015.04.014
Abstract:
Objective To analyze and compare the viral replication in patients with hepatitis B virus( HBV) when serum markers HBe Ag and HBe Ab are both positive,or HBe Ag alone is positive,or HBe Ab alone is positive,or both are negative. Methods Electrochemiluminescence method was used to detect serum markers of HBV,and the samples with HBe Ag and HBe Ab being both positive,or HBe Ag alone being positive,or HBe Ab alone being positive,or both being negative were screened out,and the HBV DNA quantitative values of the samples were determined. Comparison of categorical data was made by chi- square test. Results Among 447 patients examined for serum markers of HBV,all were positive for HBs Ag. HBe Ag and HBe Ab were simultaneously detected in 32 cases,with a positive rate of 7. 16%. Of the 32 cases,84. 38% had HBV DNA levels of < 5 × 102 copies / ml,12. 50% had HBV DNA levels between 5 × 102 copies / ml and 1 × 104 copies / ml,and3. 13% had HBV DNA levels between 1 × 104 copies / ml and 1 × 107 copies / ml. The HBV DNA level of the HBe Ag / HBe Ab- positive group was significantly lower than that of the HBe Ag- positive group( χ2= 13. 21,P < 0. 01); the HBV DNA level of the HBe Ab- positive group was significantly lower than that of the HBe Ab- negative group( χ2= 74. 12,P < 0. 01). A total of 218 cases had negative HBe Ag,and 9( 4. 13%) of them had HBV DNA levels of >1 ×104copies / ml. Conclusion Being positive for both HBe Ag and HBe Ab is considered to be rare in the past; however,it is commonly seen clinically,and a proportion of patients have a relatively high level of viral replication. The viral replication weakens when HBe Ab appears. In cases of negative serum HBe Ag,some patients still show a high level of viral replication. Therefore,the presence or absence of HBe Ag cannot be regarded as the evidence in the assessment of antiviral efficacy and infectivity.

Li Jing, Liu ZhiQuan, Lu YuFeng, Li YuXiao, Li BingShun
2015, 31(4): 537-540. DOI: 10.3969/j.issn.1001-5256.2015.04.015
Abstract:
Objective To investigate the liver pathological changes and features of hepatitis B virus( HBV) DNA in chronic HBV infection patients with normal alanine transaminase( ALT) and mild ALT elevation. Methods A total of 1123 chronic HBV infection patients with normal ALT and mild ALT elevation who were admitted to the Fifth Hospital of Shijiazhuang and had liver biopsy from January 2005 to December 2013 were retrospectively analyzed and divided into < 40 years group and ≥40 years group. The inflammation grade of liver tissue( G) and stage of fibrosis( S) among patients with positive and negative HBe Ag and with normal ALT and mild ALT elevation in the two groups were analyzed. The correlations of age with inflammation grade,fibrosis stage,and HBV DNA level were also analyzed. Comparison of continuous data between the two groups was made by t test,and comparison of categorical data was made by chi- square test. Then Spearman correlation analysis was performed. Results Compared with the < 40 years group,the ≥40 years group had a significantly higher proportion of ≥G2 patients( P < 0. 001). Patients with normal ALT and mild ALT elevation,regardless of positive or negative HBe Ag,had a significantly higher proportion of ≥S2 individuals with increasing age( P < 0. 001). Age was positively correlated with inflammation grade and fibrosis stage( r = 0. 219 and 0. 293,P < 0. 001 for both). Compared with patients in the < 40 years group,patients with negative HBe Ag and mild ALT elevation in ≥40 years group had significantly different HBV DNA levels( P < 0. 05). Conclusion The inflammation grade of liver tissue and fibrosis stage in chronic HBV infection patients with normal ALT and mild ALT elevation increase with age,which can be considered as a factor for the progression of disease.

Li CaiDong, Chen XiLian, Tian PengFei, Li HuiJun, Wu Bin
2015, 31(4): 541-545. DOI: 10.3969/j.issn.1001-5256.2015.04.016
Abstract:
Objective To investigate the correlation between the percentages of T lymphocyte subsets( CD3+T,CD4+T,CD8+T,and CD4+/ CD8+T) and CD4+CD25+regulatory T cells( Treg cells) and hepatitis B virus( HBV) DNA level in the peripheral blood of chronic hepatitis B( CHB) patients. Methods We chose 175 patients with HBV infection,who visited The Second People' s Hospital of Lanzhou from July to December,2012. The patients were divided into CHB group( n = 63) group and asymptomatic carrier( ASC) group( n =112). In the same period,50 healthy examinees served as control group. The percentages of CD3+,CD4+,CD8+,and CD4+/ CD8+T lymphocytes and CD4+CD25+Treg cells in the serum of three groups were measured by flow cytometry. HBV DNA level was analyzed by quantitative real- time PCR. The comparison of means between multiple groups was performed by analysis of variance. Further comparison between any two means was performed by LSD- t test. Correlation analysis was performed by Pearson's correlation test. Results The percentage of CD4+CD25+Treg( 30. 97% ± 18. 78%) in the peripheral blood of CHB patients was significantly higher than that of the control group( 27. 30% ± 17. 59%)( P < 0. 05). Compared with the control group,the CHB and ASC groups had significantly reduced percentages of CD3+and CD4+T lymphocytes and CD4+/ CD8+T lymphocyte ratio( P < 0. 05) and a significantly increased percentage of CD8+T lymphocytes( P < 0. 05). There was a positive correlation between the percentage of CD4+CD25+Treg cells and HBV DNA level in the ASC and CHG groups( r = 0. 501 and 0. 682,P < 0. 05 for both). Conclusion There are normal percentages of T lymphocyte subsets in HBV infection patients. HBV DNA can lead to an increased percentage of CD4+CD25+Treg cells,indicating that the imbalance of CD4+CD25+Treg and CD4+/ CD8+T cells plays an important role in the chronic progression of hepatitis B.

2015, 31(4): 546-550. DOI: 10.3969/j.issn.1001-5256.2015.04.017
Abstract:
Objective To investigate the relationship of hepatic immune cells( CD4+,CD8+,CD20+,and CD57+T lymphocytes) with liver pathology and clinical relevance in chronic hepatitis B( CHB) patients with different HBe Ag status. Methods A total of 70 CHB patients admitted to our hospital from January 2008 to December 2013 underwent liver biopsy,among whom 38 were HBe Ag positive and 32 were HBe Ag negative. Immunohistochemistry was used to examine the expression of CD4+,CD8+,CD20+,and CD57+T lymphocytes in hepatic tissues,and the correlation between their expression and clinical relevance was analyzed in patients with different HBe Ag status.Ranked data were analyzed by Kruskal- Walls H test. Comparison between groups was made by Nemenyi test. Correlation analysis was made by linear regression method. Results When inflammation reached to the level of G3- G4 in patients with either positive or negative HBe Ag,the expression of hepatic CD8+and CD20+cells in them was significantly higher than that in patients with inflammation level of G1( all P < 0. 05). When the levels of inflammation reached G4 in patients with positive HBe Ag and G3 in those with negative HBe Ag,the expression of hepatic CD4+cells was significantly higher than that in patients with G1 inflammation( all P < 0. 05). In patients with negative HBe Ag,the CD4+,CD8+,CD20+,and CD57+lymphocytes all showed a positive correlation with alanine aminotransferase( ALT) level( r = 0. 353,0. 628,0. 693,and 0. 540,respectively; all P < 0. 05). In addition,CD20+lymphocytes also showed a positive correlation with hepatitis B virus( HBV) DNA( r = 0. 378,P < 0. 05). However,in patients with positive HBe Ag,only CD8+and CD20+lymphocytes showed a positive correlation with ALT level,and no correlation was found between all lymphocyte populations and HBV DNA. Conclusion The expression of CD4+,CD8+,and CD20+lymphocytes was significantly correlated with the grade of inflammation in hepatic tissues in patients with different HBe Ag status,whereas the correlations between hepatic immune cells and levels of ALT and HBV DNA vary.

2015, 31(4): 551-555. DOI: 10.3969/j.issn.1001-5256.2015.04.018
Abstract:
Objective To investigate the expression characteristics of Treg,Tr1,and Th17 cells in the peripheral blood of patients with chronic hepatitis B( CHB) and their correlations with the state of CHB. Methods A total of 40 patients with mild- to- moderate CHB and40 patients with severe CHB who were admitted to The 180 th Hospital of PLA from January 2013 to June 2014 were included into this study,and 40 healthy people with normal liver function were recruited as control group. Peripheral blood was collected from CHB patients and healthy controls,and then the percentages of Treg,Tr1,and Th17 cells in peripheral blood were determined by flow cytometry. The levels of Foxp3 mRNA and RORγt mRNA in serum were measured by real- time PCR,and the expression levels of TGF- β1,IL- 10,and IL-17 were measured by ELISA. Comparison of continuous data between the groups was made by one- way ANOVA analysis and LSD- t test.Results( 1) Compared with the control group,the two groups of CHB patients had significantly higher percentages of Tr1,Treg,and Th17cells( P < 0. 05),and had significantly higher levels of Foxp3 mRNA and RORγt mRNA( P < 0. 05) and levels of TGF- β1,IL- 10,and IL- 17( P < 0. 05),while the two groups of CHB patients had significantly lower Treg / Th17 ratio( P < 0. 05) and Foxp3 / RORγt ratio( P< 0. 05) than the healthy controls.( 2) The patients with severe CHB had significantly higher percentages of Treg,Tr1,and Th17 cells( P< 0. 05),and had significantly higher levels of Foxp3 mRNA and RORγt mRNA( P < 0. 05) and levels of TGF- β1,IL- 10,and IL- 17( P < 0. 05),as compared with the patients with mild- to- moderate CHB,while the patients with severe CHB had significantly lower Treg/Th17 ratio( P < 0. 05) and Foxp3 / RORγt ratio( P < 0. 05) than those with mild- to- moderate CHB. Conclusion The expression imbalance of Treg cells( especially Tr1 cells) and Th17 cells in CHB patients is positively correlated with the progression of the disease; therefore,it may be important to correct the expression imbalance of Treg cells and Th17 cells in the treatment of CHB. Meanwhile,monitoring the percentages of Treg cells( especially Tr1 cells) and Th17 cells is helpful for assessing the clinical outcomes of CHB patients and guiding the clinical treatment.

2015, 31(4): 556-559. DOI: 10.3969/j.issn.1001-5256.2015.04.019
Abstract:
Objective To investigate the expression and significance of phosphorylated p38mitogen- activated protein kinase( p- p38MAPK)in mice with acute liver failure induced by D- galactosamine( D- Gal N) / lipopolysaccharide( LPS) and patients with HBV- related acute-on- chronic liver failure( HBV- ACLF). Methods C57 BL /6 mice induced by D- Gal N / LPS were used to establish an acute liver failure model,and experimental groups were set up at 0,0. 5,1,2,4,6,and 8 hours( n = 4 for each group). All mice were sacrificed and the samples of liver tissues were given HE staining to observe pathological changes. Western blotting and immunohistochemical staining were used to perform semiquantitative analysis and detect the expression of p- p38 MAPK in liver tissues. Meanwhile,the expression of p-p38 MAPK in patients with HBV- ACLF,hepatitis B cirrhosis,and chronic hepatitis B was also observed. Independent- samples t test was used to draw comparison between groups. Results Western blotting showed that the expression of p- p38 MAPK in liver tissue homogenate increased with time. The semiquantitative analysis showed that the expression was significantly higher in the 6 h group than in the control group( t =- 2. 727,P = 0. 034). Immunohistochemical staining showed that liver inflammation aggravated with the survival time,and p-p38 MAPK was expressed by sinus cells at early stage,and then by liver cells with the damage continued in mice,and there were lots of p-p38MAPK- positive liver cells around the necrotic liver tissues. Expression of p- p38 MAPK was very low in normal human liver tissues; however,tumor- infiltrating lymphocytes and p- p38MAPK- positive liver cells could be seen in liver tissues of patients with chronic hepatitis B. The expression of p- p38 MAPK was increasingly observed with the course of the disease,which was consistent with the aggravation of the disease. Conclusion The expression of p- p38 MAPK is found positively correlated with the liver tissue damage in the mouse model of acute liver failure induced by D- Gal N / LPS,implying that p- p38 MAPK plays a significant role in the development of acute hepatic failure. In HBV- ACLF patients,the p- p38 MAPK signaling pathway may play a critical role in the development of liver failure.

Sun JianMin, Hu QingJun
2015, 31(4): 560-563. DOI: 10.3969/j.issn.1001-5256.2015.04.020
Abstract:
Objective To investigate the relevance between relapse and course of treatment in genotype 1 chronic hepatitis C( CHC) patients with slow virologic response. Methods Totally 157 genotype 1 CHC inpatients or outpatients were selected from the Third People' s Hospital of Jiaozuo and the People's Hospital of Jiaozuo from April 2010 to March 2013. The patients were treated with interferon α- 1b in conjunction with ribavirin. At 6 months of the initial treatment,51 patients with slow virologic response were randomly divided into groups A( 24 cases) and B( 27 cases),which received continued treatment for another 6 and 12 months,respectively. A 1- year follow- up of patients was performed after withdrawal of treatment. Adverse reactions in patients receiving the antiviral therapy were assessed. Furthermore,group comparisons were performed on the clearance rate of hepatitis C virus( HCV) RNA and normalization rate of alanine aminotransferase( ALT) at withdrawal of treatment,as well as the CHC relapse rate and ALT normalization rate at 6 months and 1 year after withdrawal of treatment. Continuous data were compared using t test,and categorical data were compared using χ2test. Results The rate of adverse reactions in patients receiving antiviral therapy had no significant difference between groups A and B( P > 0. 05). At withdrawal of treatment,there were no significant differences between groups in terms of HCV RNA clearance rate( 95. 65% vs 92. 59%) and ALT normalization rate( 95. 65% vs 88. 89%)( χ2= 0. 02 and 0. 13,respectively,both P > 0. 05). At 6 months and 1 year after withdrawal of treatment,the CHC relapse rate in group B was significantly lower than that in group A( 20. 00% vs 50. 00%,χ2= 4. 69,P < 0. 05; 36. 00% vs68. 18%,χ2= 4. 85,P < 0. 05); the ALT normalization rate in group B was nonsignificantly higher than that in group A( 84. 00% vs59. 09%,χ2= 3. 63,P > 0. 05; 72. 00% vs 50. 00%,χ2= 2. 40,P > 0. 05). Conclusion To extend the 6- month course of treatment can significantly reduce the relapse following slow virologic response in patients with genotype 1 CHC.

2015, 31(4): 564-568. DOI: 10.3969/j.issn.1001-5256.2015.04.021
Abstract:
Objective To evaluate the efficacy of thymosin ɑ1 combined with arsenic trioxide in the treatment of advanced primary liver cancer( PLC). Methods A total of 59 patients with advanced PLC who were admitted to Jiangyan Hospital of Traditional Chinese Medicine from July 2011 to July 2014 were divided into two groups: control group and combination therapy group. The two groups were given symptomatic and supportive treatment to protect the liver. In addition,29 cases in the control group were treated with arsenic trioxide,while 30 cases in the combination therapy group were administrated with thymosin ɑ1 combined with arsenic trioxide. Comparison of continuous data between the two groups was made by independent- samples t test,and comparison of categorical data was made by chi- square test. Results There was a significant difference in clinical benefit rate between the control group and the combination therapy group( 37. 9% vs66. 7%,χ2= 4. 88,P < 0. 05). The combination therapy group had significantly higher improvement rate of the quality of life( 63. 3% vs37. 9%,χ2= 3. 81,P < 0. 05) and the pain remission rate( 76. 7% vs 44. 8%,χ2= 6. 28,P < 0. 05) than the control group. The levels of alpha fetal protein,carcinoembryonic antigen,carbohydrate antigen 199,and gamma glutamyl transpeptidase decreased in both groups,and the combination therapy group had significantly higher decreases in these indices than the control group( P < 0. 05). The combination therapy group had significantly increased percentages of CD3+and CD4+T cells and CD4+/ CD8+ratio( P < 0. 05) and a significantly reduced percentage of CD8+T cells( P < 0. 01) after treatment. However,there was no significant difference in toxic or side effects between the two groups. Conclusion For patients with advanced PLC,the combination of thymosin ɑ1 and arsenic trioxide can improve the quality of life and the immune function of patients,and no obvious toxic or side effects are found. So it holds promise for clinical application.

Abstract:
Objective To investigate the efficacy of short- term nutritional intervention in patients with primary hepatocellular carcinoma treated by transcatheter arterial chemoembolization. Methods Sixty patients with primary hepatocellular carcinoma who were admitted to Beijing Youan Hospital to receive transcatheter arterial chemoembolization from January 2012 to October 2012 were equally and non- randomly divided into two groups: nutrition group and control group. The two groups were all given nutrition guidance after transcatheter arterial chemoembolization. The nutrition group was given 15 g liver essentials twice a day( one in the morning and the other in the evening) by oral administration for 4 weeks,while the control group was given routine diet for 4 weeks. Comparison of data between the two groups was made by independent- samples t test. Results After 4 weeks of continuous treatment,the two groups had significantly increased body weight( P< 0. 05),arm muscle circumference( P < 0. 05),and triceps skinfold thickness( P < 0. 05). The two groups had significantly increased total protein( 67 ± 13 g / L vs 72 ± 9 g / L,P = 0. 04; 66 ± 10 g / L vs 74 ± 8 g / L,P = 0. 02) after treatment,and there was a significant difference in changes in total protein after treatment between the two groups( P = 0. 04). The nutrition group had significantly increased albumin( 34. 7 ± 2. 9 g/L vs 39. 9 ± 3. 5 g/L,P = 0. 03) and cholinesterase( 3342 ± 415 U/L vs 4600 ± 459 U/L,P = 0. 01) after treatment,and there was a significant difference in changes in albumin( P = 0. 03) and cholinesterase( P = 0. 03) after treatment between the two groups.Conclusion For patients with primary hepatocellular carcinoma treated by transcatheter arterial chemoembolization,oral administration of liver essentials improves their nutritional status and liver function,so as to increase their tolerance to subsequent treatments.

2015, 31(4): 578-581. DOI: 10.3969/j.issn.1001-5256.2015.04.024
Abstract:

Objective To observe the effect of plasma exchange( PE) therapy for removing serum interleukin- 6( IL- 6),tumor necrosis factor alpha( TNFα),and interferon gamma( IFNγ) in patients with liver failure,and to assess the value of artificial liver support system in the treatment of liver failure. Methods The study included 36 patients with liver failure who were hospitalized in the First Affiliated Hospital of Bengbu Medical College from February 2012 to February 2013. Blood samples were collected before PE and the next morning after multiple treatments. Plasma TNFα,IL- 6,and IFNγ levels were measured by ELISA. Between- group comparison of measurement data before and after treatment was made by independent- samples t test,and comparison of mean values between groups was made by analysis of variance. Results All the 36 liver failure patients had significantly lower levels of TNFα( 381. 23 ± 190. 57 ng / L vs 274. 12 ± 212. 30 ng / L,P< 0. 05),IL- 6( 77. 9 ± 83. 09 ng / L vs 54. 8 ± 63. 32 ng / L,P < 0. 05),and IFNγ( 534. 65 ± 471. 19 ng / L vs 259. 65 ± 312. 26 ng / L,P< 0. 05) after treatment than before treatment. According to the severity of clinical manifestations,the patients with subacute or acute- on- chronic( subacute) liver failure were divided into early stage,middle stage,and advanced stage groups. There were significant differences in IL- 6 and TNFα decreases between the early stage,middle stage,and advanced stage groups( P < 0. 05). IFNγ decrease significantly differed between the early stage or middle stage group and advanced stage group( P < 0. 05),but not between the former two groups( P > 0. 05). After PE therapy,29 out of 36 liver failure patients recovered well,while the remaining 7 patients deteriorated. The recovered group had significantly greater decreases in TNFα( 122. 58 ± 57. 64 ng / L vs 42. 45 ± 19. 86 ng / L,P < 0. 05),IL- 6( 26. 93 ± 7. 25 ng / L vs 6. 71 ± 3. 55 ng / L,P < 0. 05),and IFNγ( 284. 06 ± 94. 31 ng / L vs 217. 47 ± 45. 76 ng / L,P < 0. 05) than the deteriorated group. The response rates of patients with acute,subacute,acute- on- chronic,and chronic liver failure were 66. 67%,85. 71%,86. 36%,and50%,respectively. Conclusion Continuous artificial liver PE therapy can effectively remove pro- inflammatory cytokines from plasma and thus improve the clinical outcomes of patients with liver failure.

2015, 31(4): 582-584. DOI: 10.3969/j.issn.1001-5256.2015.04.025
Abstract:

Objective To investigate the relationship between zonula occludens- 1( ZO- 1) level and blood- brain barrier permeability in rats with hepatic encephalopathy( HE). Methods One hundred and eighty Sprague- Dawley rats were equally and randomly divided into control and HE( 4,8,and 12 h) groups of 45 animals each. Rats were given D- galactosamine( 400 mg / kg) and lipopolysaccharide( 100 μg/kg) by intraperitoneal injection to build an HE model. At 4,8,and 12 h after injection,blood ammonia concentration,Evans blue( EB) content,and brain water content were measured,and ZO- 1 mRNA level in the blood- brain barrier was assayed by real- time Q-PCR. Measurement data were analyzed using the least significant difference test( with homogeneous variances) and Dunnett T3 test( with heterogeneous variances). Results At 2 h after injection,the rats in the HE groups began to show HE symptoms. At 4 h after injection,the rats showed significant increases( P < 0. 001 for all) relative to the controls in blood ammonia concentration( 74. 27 ± 1. 77 μmol / L vs33. 85 ± 1. 50 μmol / L,),EB content( 4. 84 ± 0. 43 μg / g vs 3. 96 ± 0. 48 μg / g),and brain water content( 78. 63 ± 0. 46% vs 76. 07 ±0. 39%); the increases in the above three indices became more significant over time in the three HE groups( F = 5983. 36,111. 54,and737. 25,respectively; P < 0. 001 for all). In contrast,ZO- 1 mRNA expression in rat brain tissue began to decrease at 4 h after injection compared with the control( 1. 282 3 ± 0. 057 4 vs 1. 457 6 ± 0. 065 4,P < 0. 001); the decrease in the relative ZO- 1 mRNA expression level became more significant over time( F = 135. 38,P < 0. 001). Conclusion Blood- brain barrier permeability enhancement and brain edema in HE rats may be associated with the decrease in ZO- 1mRNA expression.

Gao AiHua, Zhang YuGuo, Nan YueMin
2015, 31(4): 594-598. DOI: 10.3969/j.issn.1001-5256.2015.04.029
Abstract:
The treatment responses to pegylated interferon alpha( PEG- IFNα) in patients with chronic hepatitis B( CHB) are associated with the genetic polymorphisms,immune status,hepatitis B virus genotype,and viral load of the host. This article reviews the recent studies on influential factors for the responses to PEG- IFNα in CHB patients. The important predictors of the clearance and seroconversion of HBs Ag and HBe Ag and sustained virological response include interleukin- 28B( IL- 28B) gene polymorphism,baseline level of interferon-inducible protein- 10,IL- 17 A,IL- 10,tumor necrosis factor- α,viral load and genotype,and changes in serum HBs Ag and HBe Ag levels at weeks 12 and 24 of treatment.

Zhang Yue, Lu: Yang, Li Xu, Gao PuJun
2015, 31(4): 599-602. DOI: 10.3969/j.issn.1001-5256.2015.04.030
Abstract:
There are 400 million individuals infected with chronic hepatitis B virus( HBV) all over the world. The management of chronic hepatitis B( CHB) has been improved markedly over the last decade,primarily due to the availability of oral nucleoside analogue( NA)therapy. Among the numerous NAs,tenofovir disoproxil fumarate( TDF) stands out for its high therapeutic efficacy,low drug resistance,and wide disease spectrum against several types of chronic CHB that can not be cured with NAs. Thus,TDF has been widely used for clinical treatment of chronic HBV infection. This paper describes the efficacy of TDF in nave and treated patients and analyzes its effect on cirrhosis. Furthermore,the safety of TDF therapy is assessed. It is considered that TDF has low resistance rate and high safety,which provides a first- line drug for CHB treatment.
Research progress in Treg/Th17 imbalance in persistent HBV infection
Cheng Ping, Xue BoYu
2015, 31(4): 603-606. DOI: 10.3969/j.issn.1001-5256.2015.04.031
Abstract:
Persistent infection with hepatitis B virus( HBV) is associated with host immune response. CD4+T cells play an important role in HBV- specific immune response. The restoration of HBV- specific T- cell response after antiviral therapy using nucleoside and nucleotide analogues is also associated with CD4+T cells. In recent years,two new subsets of CD4+T cells,namely regulatory T cells( Tregs)and T helper 17 cells( Th17 cells),have been identified and shown to be related to disease progression and liver damage in patients with persistent HBV infection. Here we primarily summarized the differentiation and function of Tregs and Th17 cells and reviewed the interaction between the two types of cells in persistent infection and their changes after clinical antiviral therapy. We hope it will be helpful to clinical immunotherapy and prognostic assessment.

Li Qiang, Zhuo QiBin, Huang YuXian, Chen Liang
2015, 31(4): 607-610. DOI: 10.3969/j.issn.1001-5256.2015.04.032
Abstract:
Sodium taurocholate cotransporting polypeptide( NTCP) was identified as the receptor for hepatitis B virus( HBV) infection in2012. The finding of HBV receptor has provided a new target for the development of new anti- HBV drugs. This article describes the bottleneck of research on HBV infection,as well as the significance of the finding of HBV and its expression regulation. Over the past two years,studies have shown that a variety of agents can block the receptor function of NTCP and then inhibit HBV entry efficiently. The inhibitors of HBV entry have become a major concept in the development of new anti- HBV drugs and may be one of future strategies for radical treatment of chronic hepatitis B.
Research advances in drug resistance to nucleos( t) ide analogues in treatment of chronic hepatitis B
Fan Xiu, Lin XiaoDong, Cen XiaoHong, Hou YuXiang
2015, 31(4): 611-613. DOI: 10.3969/j.issn.1001-5256.2015.04.033
Abstract:
Antiviral treatment is the key in the treatment of chronic hepatitis B. The long- term antiviral therapy with nucleos( t) ide analogues may lead to the viral gene mutations and drug resistance,and then the sensitivity of virus to the drug is decreased. In this study,the point mutations associated with four nucleos( t) ide analogues and the incidence of mutations were investigated. The rate of drug resistance to lamivudine was highest and that of resistance to entecavir was lowest. Recent research showed that hepatitis B virus( HBV) genotype was associated with drug resistance to nucleos( t) ide analogues. In order to prevent drug resistance,the indications for antiviral therapy should be determined strictly,and then the nucleos( t) ide analogues with high efficacy and low drug resistance can be selected. And if drug resistance develops,it is necessary to add or change to another nucleos( t) ide analogue without cross resistance.
Research progress in dynamic evolution characteristics of nucleos( t) ide analogue-resistant mutants
Wang Yang, Liu Shuang, Zhou Li, Zheng SuJun, Duan ZhongPing
2015, 31(4): 614-617. DOI: 10.3969/j.issn.1001-5256.2015.04.034
Abstract:
Long- term antiviral therapy with nucleos( t) ide analogues against hepatitis B virus may lead to the occurrence of drug- resistant viral mutations. As a challenging topic in antiviral research,the problem of drug- resistant mutations may be associated with the aggregation of chronic hepatitis B and the development of primary hepatic carcinoma. In- depth understanding of the evolution characteristics of drug-resistant mutants during long- term antiviral therapy will allow a selection of appropriate clinical drug resistance monitoring approach. Within the time interval between the occurrence of genotypic resistance and virological breakthrough,dynamic monitoring of variations in the proportion of drug- resistant variants in the quasispecies pool and timely change of the therapeutic regimen will help to optimize the treatment of chronic hepatitis B and develop effective antiviral drugs.

Wu ZhangHui, Wei Jia
2015, 31(4): 618-621. DOI: 10.3969/j.issn.1001-5256.2015.04.035
Abstract:
Multiple etiological factors are integrally involved in the development of hepatitis B virus( HBV) infection. Interleukin- 10( IL-10) is an essential cytokine of immune regulation,and IL- 10 gene promoter polymorphism affects its mRNA transcription and serum level.IL- 10 is related to the prognosis of HBV infection. This review briefly discusses the association of IL- 10 gene polymorphism and its serum level with the prognosis of HBV infection,and summarizes the role of IL- 10,as an anti- inflammatory cytokine,in host immune function,the prognosis and progression of HBV infection,and HBV- related complications. IL- 10 gene polymorphism and its serum level are closely associated with inflammatory response after HBV infection,influence HBV clearance,and are related to the severity of HBV- related liver injury,liver cirrhosis,and hepatocellular carcinoma. The determination of IL- 10 gene and serum levels may provide a predictive marker for the prognosis of HBV infection.

Zhang Can, Wan Hui, Chen Hong, Zhang Kai
2015, 31(4): 622-625. DOI: 10.3969/j.issn.1001-5256.2015.04.036
Abstract:
The infection / clearance and antiviral therapy of hepatitis B virus( HBV) are affected by various factors,such as the host,virus,and environment. Recent studies have proven that interleukin 28B( IL- 28B) polymorphisms are highly associated with the clearance and antiviral therapy of hepatitis C virus. Since then,great attention has been paid to the role of IL- 28 B genetic variations in chronic hepatitis B( CHB),with a research focus on the loci rs12979860,rs12980275,and rs8099917. This paper reviews the role of IL- 28 B polymorphisms in the infection / clearance of HBV and interferon therapy of CHB. Despite the conflicting findings,IL- 28 B polymorphisms are considered to have a potential clinical value in the field of CHB.

Shen Min, Fan HuaiYan, Wei Jia
2015, 31(4): 630-634. DOI: 10.3969/j.issn.1001-5256.2015.04.038
Abstract:
Nonalcoholic fatty liver disease( NAFLD) is prevalent in patients with characteristics of metabolic syndrome. The main clinicopathological manifestations of NAFLD are fatty degeneration of liver parenchyma cells and fat storage,which can progress to liver cirrhosis and eventually lead to liver failure. Toll- like receptor 4( TLR4) signaling pathway is involved in the development and progression of NAFLD. At present,the role of TLR4 in the onset of NAFLD is highly valued by clinical doctors. This paper reviews the structure of TLR4,the composition of TLR4 signaling pathway,the regulation of TLR4 expression,the function of TLR4,and the relationship between TLR4 and NAFLD,suggesting that TLR4 signaling pathway is going to be an important research field in the treatment of NAFLD in the future.

Abstract:
Epithelial cellular adhesion molecule( Ep CAM) is a transmembrane glycoprotein expressed in epithelial tissues and most epithelial- derived malignant tumors. Ep CAM is associated with cell adhesion,migration,proliferation,and differentiation,as well as tumor development and progression. In recent years,Ep CAM has been identified as a stem cell marker of hepatocellular carcinoma( HCC). This paper elucidates the roles of Ep CAM in the diagnosis,treatment,and prognosis of HCC,which shed light on the potential molecular targeted therapy in future.
Advances in multidisciplinary individualized treatment of refractory hepatic alveolar echinococcosis
Abuduaini Abulizi, Wen Hao
2015, 31(4): 639-641. DOI: 10.3969/j.issn.1001-5256.2015.04.040
Abstract:

Hepatic alveolar echinococcosis( HAE) is a zoonotic parasitic disease that seriously threatens the population in western China and compromises patients' quality of life. With the continuous improvement in radical resection rate in recent years,late- stage HAE patients that were incurable in the past now have the opportunity for radical resection. However,patients who are not suitable candidates for radical resection still suffer from various complications and poor quality of life. Therefore,HAE is still considered a refractory and complex disease. The simple empirical treatment model provided by traditional professional discussion is unable to satisfy the treatment of advanced refractory HAE as it is unable to integrate specialized,standardized clinical skills for diagnosis and treatment. Multidisciplinary individualized treatment( MDT) organically integrates the advantages of the available treatment into a reasonable individualized comprehensive treatment regimen. This review summarizes the advances in MDT for HAE as the best option to increase long- term survival,and suggests MDT as the first- line treatment for late- stage refractory hepatic alveolar echinococcosis.

Wang XiaoTong, Han Tao
2015, 31(4): 642-645. DOI: 10.3969/j.issn.1001-5256.2015.04.041
Abstract:
