In 2016, the World Health Organization set an ambitious goal of reducing viral hepatitis-related deaths by 65% by 2030. The key to this goal is to reduce viral hepatitis-related HCC deaths. Liver cancer is the fourth most common malignant tumor and the second leading cause of cancer death in China. The onset of HCC is insidious, and most patients are already in the middle and late stage when diagnosed. Despite the great progress on management of HCC, the therapeutic effect and prognosis of HCC are still unsatisfactory. Therefore, multi-dimensional and comprehensive analysis of the mechanism of liver cancer, improving the early screening, diagnosis and treatment rate of liver cancer are the key points of reducing the harm of liver cancer in China. In recent years, multi-omics studies have been widely applied in the field of liver cancer, providing a basis for the pathogenesis of liver cancer, early detection and diagnosis, development of individual treatment strategies and prognosis assessment. This issue will focus on the application of genomics, proteomics, metabolomics and imaging omics in early screening, diagnosis and treatment of liver cancer.

OBJECTIVE: This study aimed to investigate DNA sequences that are substantially homologous to the corresponding RNA sequence sections of the hepatitis C virus (HCV). These DNA sequences are present in the whole DNA extracted from peripheral blood mononuclear cells (PBMCs) of HCV-negative subjects. We presumed that these experimentally proven 5'-noncoding region (5'-NCR) homologous DNA sequences could be contained in the extrachromosomal circular DNA (eccDNA) fraction as part of the whole cellular DNA. METHODS: Home-made polymerase chain reaction (PCR) with whole cellular and isolated eccDNA, nucleotide basic local alignment search tool (BLASTn) alignments, and tests for patterns of methylation in selected sequence sections were performed. RESULTS: The PCR tests revealed DNA sequences of up to 320 bp that broadly matched the corresponding sequence sections of known HCV genotypes. In contrast, BLASTn alignment searches of published HCV 5'-NCR sequences with human genome databases revealed only sequence segments of up to 36 bp of the 5'-NCR. The composition of these sequences shows missing base pairs, base pair mismatches as well as complete homology with HCV reference sequences. These short sequence sections are present in numerous copies on both the same and different chromosomes. The selected sequence region within the DNA sequences of the 5'-NCR revealed a broad diversity of individual patterns of methylation. CONCLUSIONS The experimental results confirm our assumption that parts of the HCV 5'-NCR genomic RNA sequences are present at the DNA level in the eccDNA fraction of PBMCs. The tests for methylation patterns therein revealed individual methylomes which could represent an epigenetic feature. The respective sequence section might be subject to genetic regulation.

Epstein-Barr virus (EBV) causes various acute and chronic diseases. Chronic active EBV infection (CAEBV) is characterized by infectious mononucleosis-like symptoms that persist for more than 6 months with high viral loads in peripheral blood and/or an unusual pattern of anti-EBV antibodies. Severe CAEBV is associated with poor prognosis with severe symptoms, an extremely high EBV-related antibody titer, and hematologic complications that often include hemophagocytic lymphohistiocytosis. However, CAEBV which led to the development of aplastic anemia (AA) has not been reported yet. A 73-year-old woman was admitted to our hospital with intermittent fever, general weakness and elevated liver enzymes. In the serologic test, EBV-related antibody titer was elevated, and real-time quantitative-PCR in peripheral blood showed viral loads exceeding 10(4) copies/microg DNA. Liver biopsy showed characteristic histopathological changes of EBV hepatitis and in situ hybridization with EBV-encoded RNA-1 was positive for EBV. Pancytopenia was detected in peripheral blood, and the bone marrow aspiration biopsy showed hypocellularity with replacement by adipocytes. AA progressed and the patient was treated with prednisolone but deceased 8 months after the diagnosis due to multiple organ failure and opportunistic infection. Herein, we report a rare case of severe CAEBV in an adult patient accompanied by AA and persistent hepatitis.

OBJECTIVETo investigate the malondialdehyde (MDA) level and paraoxonase-1 (PON-1) activity in the serum and seminal plasma of infertile men with chronic viral hepatitis and their influence on the semen parameters of the patients.

METHODSWe collected serum and semen samples from 42 infertile men, 45 infertile males with chronic viral hepatitis, and 50 healthy fertile men as controls. We measured the MDA level in the serum and seminal plasma by spectrophotometry, detected the PON-1 activity by spectrophotometry, and determined the sperm DNA fragmentation index (DFI) by acridine orange fluorescence staining.

RESULTSThe MDA level was significantly higher but the PON-1 activity remarkably lower in the serum and seminal plasma of the infertile males with chronic viral hepatitis than in the healthy controls and infertile patients (P <0.01 or P <0.05). Total sperm motility and sperm survival rate were significantly lower while the sperm DFI markedly higher in the former than in the latter two groups (P <0.01 or P <0.05). No statistically significant difference was found among the three groups in sperm concentration (P >0.05). The WBC counts in the semen of the infertile and infertile with chronic viral hepatitis groups were significantly higher than that in the health controls (P <0.05). The MDA level and PON-1 activity in the seminal plasma were positively correlated with those in the serum in the infertile males with chronic viral hepatitis (r=0.57 or 0.48, P <0.01).

CONCLUSIONVirus-induced chronic active hepatitis enhances oxidative stress in the reproductive system, aggravates sperm damage, and affects sperm quality parameters.

BACKGROUND AND AIMS: The precise identification of true inactive hepatitis B carrier is difficult due to frequent fluctuations in Hepatitis B virus (HBV) DNA and serum transaminase levels, needing serial determinations for a period of at least one year. Hence we correlated the hepatitis B surface antigen (HBs Ag) titer of untreated Hepatitis B e Antigen (HBe Ag)-negative patients with their corresponding HBV DNA and alanine aminotransferase (ALT) levels, classified these patients as either inactive carrier or patients in the reactivation phase using the American Association for the Study of Liver Diseases (AASLD) guidelines and finally determined if there was a significant difference in HBs Ag titer between these groups.
METHODS: A cross sectional retrospective study was done. All HBe Ag- negative Chronic hepatitis B (CHB) patients who had their HBs Ag titer, HBV DNA and ALT done at National Kidney and Transplant Institute (NKTI) were obtained and clinical information was abstracted from their case records. A total of 40 patients were included in the study.
RESULTS: The mean HBs Ag titer among untreated HBe Ag negative CHB patients was 3037.04 IU/mL (SD +/- 8718.94 IU/mL). Using Spearman's coefficient of correlation, HBs Ag was found to be directly correlated with HBV DNA (R = 0.821, p = 0 < 0.05) and serum ALT (R = 0.654, p = 0 < 0.05). Moreover, using Mann Whitney T Test, the mean difference in HBs Ag titer between inactive carrier group (mean 103.72 IU/mL, SD +/- 144.25) and reactivation phase group (mean 5690.99 IU/mL, SD +/- 11517.39) was significant (p value = 0 < 0.05).
CONCLUSION: HBs Ag titer was found to be directly correlated with HBV DNA and ALT. To our knowledge, this is the first local study done that supports the concept that HBs Ag titer can provide complementary information in differentiating patient as true inactive carrier from those in the reactivation phase.

Prediction of liver fibrosis progression has a key role in the management of chronic viral hepatitis, as it will be translated into the future risk of cirrhosis and its various complications including hepatocellular carcinoma. Both hepatitis B and C viruses mainly lead to fibrogenesis induced by chronic inflammation and a continuous wound healing response. At the same time direct and indirect profibrogenic responses are also elicited by the viral infection. There are a handful of well-established risk factors for fibrosis progression including older age, male gender, alcohol use, high viral load and co-infection with other viruses. Metabolic syndrome is an evolving risk factor of fibrosis progression. The new notion of regression of advanced fibrosis or even cirrhosis is now strongly supported various clinical studies. Even liver biopsy retains its important role in the assessment of fibrosis progression, various non-invasive assessments have been adopted widely because of their non-invasiveness, which facilitates serial applications in large cohorts of subjects. Transient elastography is one of the most validated tools which has both diagnostic and prognostic role. As there is no single perfect test for liver fibrosis assessment, algorithms combining the most validated noninvasive methods should be considered as initial screening tools.

Viral hepatitis was the most common infectious disease in china. But the diagnosis and treatment were varied because the viral hepatitis patients were hospitalized in different kinds of hospital such as infectious disease hospital, general hospital and Chinese medical hospital. It was necessary to know clinical characters and information of viral hepatitis patients in different hospitals. The general information, subtype distribution, prognosis, complication, medication and relations of onset with solar term from 41 180 viral hepatitis patients based on HIS data were analyzed. It was found that the age of patients between 18 to 59 years old was most; most patients were males. The national basic medical insurance was the most type of payment. The outcome of viral hepatitis in the youth and female were better than that in the old and male. Acute hepatitis was easer to restore than chronic hepatitis. Liver cirrhosis and hepatocellular carcinoma were the two most complications. The peak of onset was during summer solstice, slight heat and great heat. The most common Chinese medicine was Diammonium glycyrrhizinate and the most common western medicine was reduced glutathione. The combination of D. glycyrrhizinate with reduced glutathione, polyene phosphatidylcholine and thymosin was the main pattern. But It was not knew if the combination of western and Chinese medicine was the most effective therapy to protect liver function. It was necessary to take deeply research of the relationship between the combination therapy and their effectiveness.

OBJECTIVETo explore the pathological and clinical characteristics of children with liver diseases by retrospective study on clinical and liver biopsy pathological data of children with liver diseases.

METHODThis retrospective analysis was performed at Beijing No. 302 Hospital among 3 932 children with liver diseases who visited the hospital from January 2001 to December 2012. The kinds of diseases were compared with the results of 1983-2000.

RESULT(1) Liver biopsy was successful in 99.72% (3 932/3 943) of cases of 2001-2012 group, complications occurred in 31 children only. (2) Of the 3 932 cases, 2 647 (67.32%) had hepatitis , non-hepatotropic viral hepatitis and non viral liver disease were seen in 365 cases (9.28%), and 920 cases (23.4%), respectively. Among 2 647 cases with viral hepatitis, 2 115 were hepatitis B (79.90%), 521 hepatitis C (19.69%), 7 were hepatitis A (0.26%) and 4 hepatitis E (0.15%), respectively. (3) In 2001-2012 group, the degrees of inflammatory activity (>G2) of liver were seen in 9.57% (202/2 111) patients with hepatitis B, while 23.57% (132/560) in 1983-2000 group. There was significant difference between the two groups (χ(2)=80.36, P=0.00 ). (4) Significant difference was observed in the rate of non viral liver disease between 2001-2012 group (23.40%, 920/3 932) and 1983-2000 group (9.61%, 98/1 020) (χ(2)=93.46, P=0.00). In 2001-2012 group, including 46 kinds of diseases, which were significantly higher than those of 1983-2000 group (18 kinds). In 2000-2012, the main causes of diseases were liver degeneration (18.26%, 168/920), drug-induced liver injury (13.59%, 125/920), fatty liver (8.80%, 81/920) and liver glycogen accumulation disease (8.70%, 80/920). While in 1983-2000 group, the main causes were liver degeneration (20.41%, 20/98), fatty liver (16.33%, 16/98), glycogen storage disease (10.20%, 10/98) and myopathy (9.18%, 9/98).

CONCLUSIONLiver biopsy in children is safe and feasible. Hepatitis B virus was ranked first in children with liver diseases in 2001-2012 group. The kinds of non viral hepatic disorders had changed and extended.
