ObjectiveTo explore expressions of the metaherin (MTDH) mRNA and its protein in hepatitis B related hepatocellular carcinoma tissues and its clinical significance.
MethodsSeventy two tissues of patients with hepa-titis B related hepatocellular carcinoma who were treated in Affiliated Taihe Hospital of Hubei Medical University from Jul. 2012 to Oct. 2013 were collected retrospectively. Quantitative PCR (Q-PCR) and Western blot methods were used to detect the expression levels of MTDH mRNA and its protein in 10 cases of hepatitis B related hepatocellular carcinoma tissues and pericarcinoma tissues. Besides, immunohistochemistry was used to determine the expression of MTDH protein in 72 cases of hepatocellular carcinoma tissues, then the relationship of expression of MTDH protein and clinico-pathological features was explored.
ResultsThe expression levels of MTDH mRNA and its protein in hepatocellular carcinoma tissues were both higher than those of pericarcinoma tissues (8.50±0.84 vs. 4.55±0.81, t=10.797, P=0.000; 0.65± 0.24 vs. 0.25±0.16,t=6.375, P=0.013). The MTDH protein was positively expressed in 42 cases (58.3%) and negatively expressed in 30 cases (41.7%) of hepatocellular carcinoma tissues. The results of logistic regression showed that,MTHD protein was up-regulated in patients with category Ⅲ of Edmondson grade (OR=4.783, 95% CI:2.663-11.918, P=0.020), microvascular invasion (OR=37.790, 95% CI:2.227-99.434, P=0.005), and lymph node metastasis (OR=7.332, 95% CI:3.325-30.669, P=0.023).
ConclusionExpressions of MTDH mRNA and its protein are both higher in hepatitis B related hepatocellular carcinoma tissue, which are correlated with poor prognosis.
Objective To study the relationship of hepatitis B virus （HBV） to spontaneous rupture of hepatocellular carcinoma （HCC-SR） and its mechanism. Method The related literatures about theory of HCC-SR were consulted and reviewed. Results The injury of small arteries was usually followed in patients with HCC-SR， which was related to vascular autoimmune injury caused by the HBV infection. The small arteries in which immune complex deposited were readily injured， as a result HCC-SR happened while vascular load increased. Conclusion The HBV infection resulted in vascular autoimmune injury maybe a important factor in the pathogenesis of HCC-SR.
Objective To evaluate the efficacy and safety of antiviral drugs for hepatitis B with YMDD motif variant. Methods We electronically searched MEDLINE (1989-April, 2004), EMBASE (1989-April, 2004), CBMdisc (expand) (1989-April, 2004), and handsearched unpublished Chinese conference proceedings. Randomized and quasi-randomized trials in patients with chronic hepatitis B with YMDD motif variant correlative to lamivudine were collected. Two reviewers extracted the data and assessed the quality of literature independently. The data were then analyzed by RevMan 4.2 software. Results Five studies involving 6 trials and 284 patients were included. According to the results of meta-analysis, antiviral therapy with adefovir plus lamivudine showed significantly better effects on the clearance of serum HBV-DNA and HBeAg and normalization of ALT than that of lamivudine alone (RR 16.61, 95%CI 2.29 to 120.71; RR 6.66, 95%CI 1.23 to 35.88 and RR 6.26, 95%CI 2.29 to 17.12 respectively); also, oxymatrine plus thymothin showed obviously better effects on the clearance of serum HBV-DNA and HBeAg (RR 2.96, 95%CI 1.26 to 6.93 and RR 2.51, 95%CI 1.05 to 5.98 respectively).But adefovir alone showed no better effects on clearance of serum HBV-DNA and HBeAg than that of lamivudine alone (RR 11.00, 95%CI 0.65 to 186.02 and RR 7.00, 95%CI 0.39 to 126.92 respectively); interferon plus lamivudine showed no better effects on the clearance of serum HBV-DNA, HBeAg and the normalization of ALT (RR 3.50, 95%CI 0.90 to 13.58; RR 4.90, 95%CI 0.70 to 35.10 and RR 2.80, 95%CI 0.91 to 8.12 respectively). Chinese herbs plus lamivudine showed no better effects on the clearance of serum HBV-DNA (RR 1.16, 95%CI 0.89 to 1.51). There were no significant side effects in the groups, except flu like symptom in the interferon group, slight kidney impairment in the adefovir group, and aggravation of rare cases in lamivudine group. Conclusions Antiviral therapy with adefovir plus lamivudine, or oxymatrine plus thymothin, shows better effects than with lamivudine alone in terms of antiviral therapy and clinical outcome improvement. However, the evidence is too weak to draw a definite conclusion in this systematic review. Larger sample size and rigorously designed randomized, double blind, placebo control trials are required for future study.
Objective To assess the effectiveness and safety of hepatitis B immunoglobulin (HBIG) in interrupting the intrauterine transmission of HBV.Methods The Cochrane Library (Issue 3, 2007), MEDLINE (1996 to April 2007), CBM (1978 to April 2007), and EMBASE (1980 to April 2007) were searched. The quality of included studies was evaluated and meta-analysis was performed. Results Four studies involving 359 participants with HBVDNA (+) were included. All the included studies were judged to be inadequate in regard to the reporting of randomization, concealment of allocation and blinding. Meta-analysis based on the included studies showed that HBIG significantly decreased the intrauterine transmission rate of HBV compared to the control group [OR 0.17, 95%CI (0.09 to 0.31), Plt;0.000 01]. No HBIG-related severe adverse reactions were reported. Conclusions HBIG is effective and safe for the interruption of intrauterine transmission of HBV. However, because of the high risk of selection and detection bias in the included studies, this evidence is not b enough. Large-scale randomised trials on the use of HIBG for the interruption of intrauterine transmission of HBV are needed
Objective To investigate the prevention of HBV reinfection in the perioperative period of liver transplantation on HBV-related diseases． Methods Published papers were collected and reviewed． Results HBV-related diseases were the main indications of liver transplantation．The prevention for HBV reinfection affects the survivals remarkably. Nowadays, a lot of medication have been used in the prevention of HBV reinfection， and the therapeutic regimens were different from each other. Conclusion Liver transplantation is an effective treatment for HBV-related disease． Appropriate prevention of HBV reinfection in the perioperative period of liver transplantation is important for the survivals of patients．
Long non-coding RNA (lncRNA) is a type of nucleic acid sequence that exceeds 200 nucleotides in length and cannot encode any complete protein. In recent years, its important regulatory role in various pathophysiological processes has been gradually clarified, however, few studies have reported its role in carcinogenic virus infection. This article summarizes the currently known lncRNAs abnormally expressed in hepatitis B virus-induced hepatocellular carcinoma, and focuses on the mechanisms of lncRNAs regulating the occurrence and development of hepatitis B virus-related hepatocellular carcinoma such as controlling virus replication and host immunity, cell cycle and proliferation, invasion and metastasis, autophagy and apoptosis of liver cancer cells, hoping to provide a theoretical basis for the molecular targeted therapy of hepatocellular carcinoma.
ObjectiveTo explore the association between viral hepatitis and extrahepatic cholangiocarcinoma (ECC).
MethodsDatabase of Medline, Embase, PubMed, CNKI, and Wanfang were searched for the articles which were related to the relationship between viral hepatitis and ECC. After the quality evaluation and the data extraction of the literatures, statistical software of RevMan 5.0 was used to perform Meta analysis.
ResultsAccording to the inclusion criteria and exclusion criteria, 9 articles were enrolled, 8 articles of them were related to hepatitis B virus(HBV) and 6 articles of them were related to hepatitis C virus(HCV). Meta analysis results showed that the HBV infection may be the risk factor for ECC(OR=1.69, 95% CI:1.32-2.17, P<0.000 1). In the United States, HCV infection may be the risk factor for ECC(OR=5.53, 95% CI:2.21-13.82, P=0.000 3), but the relationship was not found in China(OR=0.82, 95% CI:0.44-1.52, P=0.520 0).
ConclusionsThe present studies suggest that HBV infection may be a high risk factor for ECC. HCV in the United States can increase the incidence of ECC, but the situation can not be found in China.
Objective?To evaluate the effectiveness of combination therapy with lamivudine (LAM) and hepatitis B immunoglobulin (HBIG) versus LAM monotherapy in prevention of hepatitis B virus recurrence after liver transplantation. Methods?Databases including MEDLINE (Ovid), PubMed, EMbase, Cochrane Central Register of Controlled Trials (CENTRAL), CBM, VIP, and CNKI were searched up to Dec. 2008. Clinical trials including randomized controlled, non-randomized concurrent-control and case-control studies about combination therapy with HBIG and LAM versus LAM monotherapy in prevention of hepatitis B virus recurrence after liver transplantation were screened. Trial selection and data extraction were conducted by two reviewers independently. Meta-analysis was performed using RevMan 5.0.18 software. Results?Eleven non-randomized concurrent-control studies involving 1 421 patients (1 035 patients in combination therapy group, and 386 patients in LAM monotherapy group) were included. The results of meta-analyses showed: Compared with LAM monotherapy group, the risks of hepatitis B virus recurrence, YMDD mutation, and death associated with HBV recurrence were significantly reduced by 73% (RR=0.27, 95%CI 0.20 to 0.37, Plt;0.000 01), 72% (RR=0.28, 95%CI 0.15 to 0.53, P=0.000 01), and 79% (RR=0.21, 95%CI 0.09 to 0.49, P=0.000 3) respectively in combination therapy group after liver transplantation; overall survival rates of both recipients and grafts in combination therapy group were similar to LAM monotherapy group (RR=1.03, 95%CI 0.95 to 1.11, P=0.51; RR=1.04, 95%CI 0.97 to 1.12, P=0.26). Conclusion?Current evidence indicates that compared with LAM monotherapy, combination therapy with LAM and HBIG could reduce the risks of hepatitis B virus recurrence, YMDD mutation, and death associated with HBV recurrence after liver transplantation.
Objective By means of evidence-based clinical practice, to find more effective treatment for a hepatitis B related nephritis patient with renal failure. Methods The following databases as Up to Date (May 2011), The Cochrane Library (Issue 5, 2011), PubMed (1978 to 2011) and CNKI (1978 to 2011) were searched to identify systematic reviews and randomized controlled trials (RCTs) of treating hepatitis B related nephritis with glucocorticoid, immunosuppressor or antiviral therapies, and the quality of collected clinical evidence was evaluated by using GRADEpro software. Results The glucocorticoid or combined immunosuppressors was not recommended for existing adverse effects and not acting on the remission of hepatitis B related nephritis and reduction of proteinuria. However, the antiviral therapy used alone was recommended for acting on the remission of hepatitis B related nephritis and the reduction of proteinuria. In view of adverse effects and expensive price of interferon, the nucleoside analogue antiviral agent was suggested. Considering the renal toxicity of adefovir and tenofovir, and possible drug-resistance of lamivudine, the entecavir (0.5 mg qd) was finally selected with patient’s agreement, and the supporting therapies such as lowering blood pressure, and protecting the kidney and liver were adopted continually. After one month treatment, 24-hour urinary protein got reduced, serum albumin got increased, kidney function got stable, and hepatitis B virus DNA quantity got reduced. Conclusion For treating hepatitis B related nephritis with kidney failure, entacavir can reduce 24-hour urinary protein, raise serum albumin, stabilize kidney function and reduce hepatitis B virus DNA in a short term, but its long-term efficacy still requires further studies.
ObjectiveTo systematically review the efficacy of different nucleosides (acids) in preventing hepatitis B virus reactivation after chemotherapy in cancer patients. MethodsThe Cochrane Library, PubMed, EMbase, Web of Science, CNKI, WanFang Data, and VIP databases were electronically searched to collect randomized controlled trials (RCTs) of different nucleosides (acids) to prevent HBV reactivation after chemotherapy in cancer patients from inception to June 7th, 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Network meta-analysis was then performed by using Stata 16.0 software. ResultsA total of 43 RCTs involving 3 269 patients were included. There were 7 interventions, namely entecavir (ETV), lamivudine (LAM), adefovir dipivoxil (ADV), telbivudine (LdT), tenofovir dipivoxil (TDF), lamivudine combined with entecavir (LAM+ETV), and lamivudine combined with adefovir dipivoxil (LAM+ADV). The results of network meta-analysis showed that the efficacy of reducing the reactivation rate of ETV, LAM, ADV, LdT, TDF, LAM+ETV, LAM+ADV were superior than the control group. The ETV, LAM and ADV were not as effective as LAM+ETV. The leading drug combinations were LAM+ETV (94.8%), LdT (81.5%) and LA+ADV (58.0%). ConclusionsCurrent evidence shows that LAM+ETV, LdT, and LA+ADV are more effective in preventing hepatitis B virus reactivation after chemotherapy in cancer patients. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
