Background: Several studies have indicated the role of quantitative hepatitis B surface antigen (HBsAg) evaluation in managing and prognosis of hepatitis B virus (HBV) infection. Thus, quantitative evaluation of HBsAg using cost-effective assays can be an important approach to managing HBV patients. Objectives: This study aimed to set up and apply an in-house quantitative enzyme-linked immunosorbent assay (ELISA) to evaluate HBsAg in research and diagnosis. Methods: New Zealand white rabbits were immunized with HBsAg. Sera were collected 28 days after immunization, and polyclonal HBsAb (antibody to hepatitis B surface antigen) were purified and evaluated. Then, the in-house quantitative ELISA was optimized. Finally, the functional characteristics of the assay were evaluated using 200 plasma samples compared to commercial ELISA and quantitative TaqMan real-time PCR. Results: The assay has a limit of detection (LOD) of 0.5 ng/mL with a specificity and sensitivity of 94% and 97%, respectively. The assay's highest coefficient of variation (CV) values for intra- and inter-assays were 7.23% and 8.59%, respectively. The correlation of the developed assay with commercial ELISA was 0.987 (P-value = 0.024). The correlations of the developed assay and commercial ELISA with quantitative TaqMan real-time PCR were 0.739 and 0.658, respectively (P-value = 0.017). Conclusions: The developed assay has a suitable sensitivity and specificity. It is also reproducible and well-correlated with commercial assays. Most importantly, it is cost-effective and, thus, can be used for detecting and quantifying HBsAg in research and diagnosis.
背景:一些研究表明,定量乙型肝炎表面抗原(HBsAg)评估在乙型肝炎病毒(HBV)感染的管理和预后中的作用。因此,使用具有成本效益的检测方法对HBsAg进行定量评估可能是管理HBV患者的重要方法。目的:本研究旨在建立并应用内部定量酶联免疫吸附试验(ELISA)来评估HBsAg在研究和诊断中的价值。方法:用HBsAg免疫新西兰大白兔。免疫28天后采集血清,纯化乙型肝炎表面抗原抗体(HBsAb)并进行评价。然后,对室内定量ELISA进行优化。最后,使用200份血浆样本与商用ELISA和定量TaqMan实时PCR进行比较,评估该检测的功能特征。结果:检测限(LOD)为0.5 ng/mL,特异性为94%,灵敏度为97%。该方法的最高变异系数(CV)值在测定组内和测定组间分别为7.23%和8.59%。与市售ELISA的相关性为0.987 (p值= 0.024)。该方法与市售ELISA与TaqMan实时荧光定量PCR的相关性分别为0.739和0.658 (p值= 0.017)。结论:所建立的检测方法具有较好的灵敏度和特异性。它也是可重复的,并与商业分析密切相关。最重要的是,它具有成本效益,因此可以在研究和诊断中用于检测和量化HBsAg。

Background: This study aimed to investigate the combined effects of resveratrol (RES) and saroglitazar (SARO) on a high-fat diet (HFD)-induced non-alcoholic fatty liver disease (NAFLD) in a rat model. Methods: In this animal study, rats were treated with RES, SARO, or a combination of both. Male rats were fed with an HFD to induce nonalcoholic steatohepatitis (NASH) and then divided into 4 groups: RES treatment, SARO treatment, combined RES and SARO treatment, and no treatment. Various parameters were measured, including body and liver weight, liver enzymes, gene expression of inflammatory markers and reactive oxygen species (ROS), protein expression levels of transforming growth factor-beta (TGF-β) and p-Smad3, and liver histology. Results: The combination of RES and SARO significantly reduced blood and hepatic lipids, attenuated weight gain, and decreased inflammatory cytokine production in a NAFLD study. The combination diminished hepatic lipid accumulation, oxidative stress, and TGF-β1 expression, suggesting antifibrotic effects. Histological evaluations showed antisteatotic and antifibrotic outcomes of the combined treatment. Improved glycemic index, blood lipids, and reduced NASH indicators (i.e., aspartate aminotransferase [AST] and alanine aminotransferase [ALT]) were observed after 6 weeks. The treatment also decreased ROS and NOX family expression, lessening oxidative stress. The inhibition of the TGF-β-Smad3 pathway in HFD-induced rats resulted in reduced NASH (P < 0.05). Conclusions: The results indicated that the group receiving the combination of RES and SARO showed a more efficient reduction in fibrosis and steatosis in the NASH model induced by an HFD than the groups receiving RES or SARO alone.
背景:本研究旨在探讨白藜芦醇(RES)和沙格列他(SARO)对高脂饮食(HFD)诱导的非酒精性脂肪性肝病(NAFLD)大鼠模型的联合作用。方法:本实验采用RES、SARO或两者联合治疗大鼠。采用HFD诱导雄性大鼠非酒精性脂肪性肝炎(NASH),并将其分为RES组、SARO组、RES + SARO联合组和不治疗组。测量体重和肝脏重量、肝酶、炎症标志物和活性氧(ROS)基因表达、转化生长因子-β (TGF-β)和p-Smad3蛋白表达水平、肝脏组织学等参数。结果:在一项NAFLD研究中,RES和SARO联合使用可显著降低血液和肝脏脂质,减轻体重增加,并减少炎症细胞因子的产生。联合用药可降低肝脏脂质积累、氧化应激和TGF-β1表达,提示抗纤维化作用。组织学评价显示联合治疗的抗脂肪变性和抗纤维化效果。6周后观察到血糖指数、血脂改善,NASH指标(即天冬氨酸转氨酶[AST]和丙氨酸转氨酶[ALT])降低。处理还降低了ROS和NOX家族的表达,减轻了氧化应激。抑制hfd诱导大鼠TGF-β-Smad3通路导致NASH减少(P < 0.05)。结论:结果表明,RES和SARO联合组比单独接受RES或SARO组更有效地减少了HFD诱导的NASH模型中的纤维化和脂肪变性。

Background: Most patients with extrahepatic metastases (EHM) from hepatocellular carcinoma (HCC) die from developing the primary tumor within the liver, not from EHM. Although surgery for primary tumors is not recommended in guidelines, some studies suggest that surgical treatment might prolong patient survival. Objectives: This study aimed to develop and validate an easy-to-use nomogram for preoperative assessment by physicians of patients with advanced extrahepatic metastatic hepatocellular carcinoma (HCC-EHM), factors associated with surgical treatment, and probability of benefit. Methods: By searching the SEER database of HCC patients with EHM by propensity score matching (PSM), 912 patients were finally included in the study. The patients in the surgery group were randomly assigned to the training and validation groups (7:3), and a nomogram was constructed to predict whether patients in the surgery group could benefit from receiving surgical treatment at the primary site and to validate the accuracy of the model and the overall survival of the surgery patients at 1, 3, and 5 years. Results: Several factors related to the grade, T staging, NM staging, tumor size, primary site surgery, alpha-fetoprotein (AFP), chemotherapy, and fibrosis score were finally included (P < 0.05). The area under the receiver operating characteristic curve (AUROC/area under the curve (AUC)) was 0.738 and 0.769 for the training and validation groups, respectively. The 1-, 3-, and 5-year survival rates were 0.725, 0.720, and 0.716, respectively. Conclusions: Based on the results, a nomogram can individually predict patients suitable for surgery and provide a reference for clinical decision-making.
背景:大多数肝细胞癌(HCC)肝外转移(EHM)患者死于肝内原发性肿瘤,而非EHM。尽管指南中不建议对原发性肿瘤进行手术,但一些研究表明,手术治疗可能会延长患者的生存期。目的:本研究旨在开发和验证一种易于使用的列线图,用于医生对晚期肝外转移性肝细胞癌(HCC-EHM)患者的术前评估、与手术治疗相关的因素以及获益概率。方法:通过倾向评分匹配(PSM)检索HCC EHM患者的SEER数据库,最终将912名患者纳入研究。手术组患者被随机分配到训练组和验证组(7:3),并构建列线图来预测手术组患者是否可以从原发部位接受手术治疗中受益,并验证模型的准确性和手术患者在1年、3年和5年的总生存率。结果:最终纳入了与分级、T分期、NM分期、肿瘤大小、原发部位手术、甲胎蛋白(AFP)、化疗和纤维化评分相关的几个因素(P<0.05)。训练组和验证组的受试者操作特征曲线下面积(AUROC/曲线下面积)分别为0.738和0.769。1年、3年和5年生存率分别为0.725、0.720和0.716。结论:基于这些结果,列线图可以单独预测适合手术的患者,并为临床决策提供参考。

Background: With the popularity of WeChat, Internet-based nursing approaches are gradually being applied to disease care, as they can better meet nursing requirements. Objectives: To explore the impact of the WeChat health management platform on the self-care ability and quality of life of patients with liver cancer undergoing interventional therapy Methods: A total of 82 patients with liver cancer who underwent interventional therapy were selected from January 2020 to January 2021 and randomly divided into the observation (n = 41) and control (n = 41) groups. The control group received routine nursing measures, while the observation group received the new nursing mode based on the WeChat health management platform. The WeChat health management platform can help patients develop health education plans, remind them of follow-up appointments, promote knowledge about nursing measures for liver cancer interventional therapies, provide feedback on medication use to doctors, and strengthen doctor–patient communication. The self-care ability and quality of life of the two groups of patients were compared before and after the intervention. Results: After the intervention, the Hamilton Anxiety Scale (HAMA) and Hamilton Rating Scale for Depression (HAMD) scores were lower in the patients of the observation group than those in the control group, indicating an improvement in the adverse moods and quality of life of patients in the observation group. Also, the psychological, physical, and social functions and overall health scores of patients in the observation group were higher than those in the control group (all P-values < 0.05). Conclusions: The WeChat health management platform could improve the self-care ability of liver cancer patients undergoing interventional therapy and their mood and quality of life, which is worthy of clinical reference.
背景:随着b微信的普及,基于互联网的护理方式逐渐被应用到疾病护理中,因为它能更好地满足护理需求。目的:探讨微信健康管理平台对肝癌介入治疗患者自我护理能力及生活质量的影响方法:选择2020年1月至2021年1月行介入治疗的肝癌患者82例,随机分为观察组(n = 41)和对照组(n = 41)。对照组采用常规护理措施,观察组采用基于微信健康管理平台的新型护理模式。微信健康管理平台可以帮助患者制定健康教育计划,提醒患者随访预约,推广肝癌介入治疗护理措施知识,向医生反馈用药情况,加强医患沟通。比较干预前后两组患者的生活自理能力和生活质量。结果:干预后,观察组患者汉密尔顿焦虑量表(HAMA)和汉密尔顿抑郁评定量表(HAMD)得分均低于对照组,表明观察组患者的不良情绪和生活质量均有改善。观察组患者的心理、生理、社会功能及整体健康评分均高于对照组(p值均< 0.05)。结论:微信健康管理平台可提高肝癌介入治疗患者的自我护理能力,改善患者的情绪和生活质量,值得临床参考。

Background: Cirrhosis is one of the most critical health problems with a great economic burden on the health system. Objectives: This study evaluated cirrhosis predictors in patients with hepatitis C virus (HCV). Methods: A total of 608 patients with HCV were included in the present study within 2011 and 2017 and divided into two groups based on the presence and absence of cirrhosis. Demographic and laboratory data (e.g., blood group, aspartate transaminase (AST), alanine transaminase (ALT), prothrombin time (PT), platelet count, anti-HCV antibodies, and virus level count) were collected by referring to patients’ files and compared between the two groups. Predictive factors were determined using the regression model. Results: In this study, 85 patients (13.9%) had liver cirrhosis. Univariate analysis showed that hepatic enzymes AST, ALT, platelet count, PT, partial thromboplastin time, international normalized ratio, and HCV ribonucleic acid levels in cirrhosis patients were significantly higher than in non-cirrhosis patients (P < 0.05). Adjusted logistic regression analysis showed age < 45 years (adjusted odds ratio (ORAdj): 1.11, P = 0.028), male gender (ORAdj: 2.08, P = 0.023), co-infection with hepatitis B virus (HBV) infection (ORAdj: 2.58, P = 0.001), and alcohol consumption (ORAdj: 1.87, P = 0.001) were predictive factors for cirrhosis in patients with HCV Conclusions: This study showed that in patients with hepatitis C, age > 45 years, male gender, alcohol consumption, and co-infection with HBV significantly increased the risk of liver cirrhosis.
背景:肝硬化是最严重的健康问题之一,给卫生系统带来了巨大的经济负担。目的:本研究评估了丙型肝炎病毒(HCV)患者肝硬化的预测因素。方法:本研究在2011年和2017年共纳入608名丙型肝炎患者,根据是否存在肝硬化分为两组。通过参考患者档案收集人口统计学和实验室数据(例如,血型、天冬氨酸转氨酶(AST)、丙氨酸转氨酶(ALT)、凝血酶原时间(PT)、血小板计数、抗HCV抗体和病毒水平计数),并在两组之间进行比较。使用回归模型确定预测因素。结果:在本研究中,85例(13.9%)患者患有肝硬化。单因素分析显示,肝硬化患者的肝酶AST、ALT、血小板计数、PT、部分凝血活酶时间、国际标准化比率和HCV核糖核酸水平显著高于非肝硬化患者(P<0.05)。调整后的logistic回归分析显示年龄<45岁(调整后的比值比(ORAdj):1.11,P=0.028),男性(ORAdj:2.08,P=0.023)、同时感染乙型肝炎病毒(HBV)感染(ORAdj=2.58,P=0.001)和饮酒(ORAdj:1.87,P=0.001,同时感染HBV显著增加肝硬化的风险。

Background: With the improvement in living standards and the change in eating habits, the prevalence of nonalcoholic fatty liver disease (NAFLD) has gradually increased, and it has become one of the most common chronic liver diseases worldwide. Objectives: In this study, we used vitamin D3 to interfere with the hyperlipidemia-induced NAFLD cell model to explore the mechanism of vitamin D in improving the lipotoxicity of liver cells by regulating the epigenetic characteristics of genes and to provide new clues for the treatment of late-stage NAFLD. Methods: GSE200765, a data chip for vitamin D3 intervention in liver cell lipotoxicity, was screened from the GEO database. They were divided into the control group (untreated), model group (oleic OA/PA), and vitamin D3 intervention group (OA/PA+SV-VD3 group). Differential expression genes between the control group and model group, model group, and vitamin D3 intervention group were screened by the GEO2R tool. Differentially expressed genes construct a target PPI network map through the STRING database and analyze the KEGG pathway of differentially expressed genes in the DAVID database. The t-test or Unpaired t-test with Welch's correction was used to analyze the expression trend of pathway genes. Results: Compared with the control group, 218 genes were up-regulated, and 255 genes were down-regulated in the model group, of which 26 genes were enriched in the complex and coagulation cascades and cell cycle pathways. After oleic OA/PA was added to HepaRG cells, the complex and coordination cascades pathway was relatively weak, and the cell cycle pathway was relatively strong. Compared with the model group, 554 genes were up-regulated, and 704 genes were down-regulated in the vitamin D3 intervention group, of which 23 genes were enriched in the apoptosis pathway. The apoptosis pathway was relatively weakened after vitamin D3 intervened in oleic OA/PA-treated HepaRG cells. The trend analysis of gene expression in the pathway showed that gene expression disorder in the complex and coagulation cascades, cell cycle, and apoptosis pathways were reversed after vitamin D3 intervention. Conclusions: Through bioinformatics, key pathway genes of vitamin D intervention on hepatocyte lipotoxicity were discovered, which were related to the complex and coordination cascades, cell cycles, and apoptosis pathways. The inhibition of vitamin D on lipotoxicity of human hepatocytes and the possible reversal mechanism was found, which provided ideas for the later treatment of NAFLD and hepatocyte damage.
背景:随着生活水平的提高和饮食习惯的改变,非酒精性脂肪性肝病(NAFLD)的患病率逐渐上升,已成为世界范围内最常见的慢性肝病之一。目的:本研究利用维生素D3干预高脂血症诱导的NAFLD细胞模型,探讨维生素D通过调节基因的表观遗传特征改善肝细胞脂毒性的机制,为晚期NAFLD的治疗提供新的线索。方法:从GEO数据库中筛选维生素D3干预肝细胞脂毒性的数据芯片GSE200765。将大鼠分为对照组(未经处理)、模型组(油酸OA/PA)和维生素D3干预组(OA/PA+SV-VD3组)。采用GEO2R工具筛选对照组与模型组、模型组、维生素D3干预组之间的差异表达基因。差异表达基因通过STRING数据库构建目标PPI网络图谱,并在DAVID数据库中分析差异表达基因的KEGG通路。采用t检验或Welch校正的Unpaired t检验分析通路基因的表达趋势。结果:与对照组比较,模型组有218个基因上调,255个基因下调,其中26个基因在复杂、凝血级联及细胞周期通路中富集。在HepaRG细胞中加入油酸OA/PA后,复杂和协调级联通路相对较弱,细胞周期通路相对较强。与模型组比较,维生素D3干预组554个基因上调,704个基因下调,其中23个基因在凋亡通路中富集。维生素D3干预油酸OA/ pa处理的HepaRG细胞后,凋亡途径相对减弱。通路基因表达趋势分析显示,维生素D3干预后,复合物和凝血级联、细胞周期和细胞凋亡通路的基因表达紊乱得到逆转。结论:通过生物信息学发现了维生素D干预肝细胞脂毒性的关键通路基因,这些通路与复杂协调的级联、细胞周期和凋亡通路有关。发现维生素D对人肝细胞脂毒性的抑制作用及其可能的逆转机制,为NAFLD的后期治疗及肝细胞损伤提供思路。

Background: Non-alcoholic fatty liver disease (NAFLD) is the most common cause of liver disorders worldwide. Regarding the shortage of evidence on NAFLD in type 1 diabetes mellitus (T1DM) and the importance of a thorough assessment of complications due to childhood diseases, this study aimed to assess the need for the early detection of NAFLD in children with T1DM. Methods: This cross-sectional study was conducted on 234 children with T1DM referred to 17 Shahrivar Hospital, Rasht, Iran. This study also assessed demographic characteristics, medical history, physical examination, laboratory tests, and hepatic ultrasound. The Mann-Whitney U and chi-square tests were used to compare the children with and without NAFLD. Additionally, univariate and multivariate logistic regressions were used to determine the predictors of NAFLD. Results: This study was conducted on 235 children with T1DM with a median age of 11.0 years (interquartile range (IQR): 8.0 - 14.0) and diabetes duration of 2.0 years (IQR: 1.0 - 4.0). The prevalence of NAFLD was estimated to be 10.2%. The children with NAFLD were significantly older (P = 0.016) and had a larger waist circumference (WC) z-score (P = 0.008) than those without NAFLD. Multiple logistic regression analyses showed that the odds of NAFLD increased with rising age (odds ratio (OR) = 1.29, 95% confidence interval (CI): 1.09 - 1.52) and WC z-score (OR = 2.39, 95% CI: 1.49 - 3.84). The cut-off point for the WC z-score was -0.025 (sensitivity = 58.3%, specificity = 72.0%). Conclusions: The NAFLD frequency in T1DM is relatively low (10.2%) and mainly consists of grade I fatty liver. The NAFLD screening should be further noticed in T1DM children with increasing age and WC as the predictors of NAFLD.
背景:非酒精性脂肪性肝病(NAFLD)是世界范围内肝脏疾病最常见的原因。鉴于1型糖尿病(T1DM)中NAFLD的证据不足,以及对儿童疾病并发症进行全面评估的重要性,本研究旨在评估早期发现T1DM儿童NAFLD的必要性。方法:本横断面研究对伊朗拉什特的17家Shahrivar医院的234名T1DM儿童进行了研究。本研究还评估了人口统计学特征、病史、体格检查、实验室检查和肝脏超声。采用Mann-Whitney U检验和卡方检验对有无NAFLD患儿进行比较。此外,采用单因素和多因素logistic回归来确定NAFLD的预测因素。结果:本研究纳入235例T1DM患儿,中位年龄11.0岁(四分位数范围(IQR): 8.0 - 14.0),糖尿病病程2.0年(IQR: 1.0 - 4.0)。NAFLD的患病率估计为10.2%。NAFLD患儿年龄显著大于非NAFLD患儿(P = 0.016),腰围(WC) z-score显著大于非NAFLD患儿(P = 0.008)。多元logistic回归分析显示,NAFLD的发生率随年龄的增加而增加(比值比(OR) = 1.29, 95%可信区间(CI): 1.09 ~ 1.52), WC z-score (OR = 2.39, 95% CI: 1.49 ~ 3.84)。WC z-score的分界点为-0.025(敏感性= 58.3%,特异性= 72.0%)。结论:T1DM患者NAFLD发生率相对较低(10.2%),以I级脂肪肝为主。在T1DM患儿中,应进一步注意NAFLD筛查,年龄和腰围增加是NAFLD的预测因素。

Background: Hepatic encephalopathy is a severe neuropsychiatric complication of decompensated cirrhosis associated with high short-term mortality. Objectives: This study aimed to evaluate the predictive value of non-invasive scoring systems and develop a prognostic nomogram to identify the risk of 3-month mortality in patients with hepatic encephalopathy. Methods: Retrospective data from 251 patients with decompensated cirrhosis and hepatic encephalopathy were collected. Clinical data and non-invasive scoring systems were compared between survivors and non-survivors using univariate and multivariate logistic regression analyses. A prognostic model was developed and validated using bootstrap resampling procedures. Results: Among the 251 patients, 40 (15.9%) died within three months. The non-survivor group had a higher incidence of complications and higher non-invasive scores (all P < 0.01). Multivariate analysis revealed that hepatorenal syndrome, spontaneous bacterial peritonitis, upper gastrointestinal bleeding, and Fibrosis-4 index were independent risk factors. A new model incorporating the Fibrosis-4 index and complications was developed, and discrimination was assessed using a bootstrap-corrected C statistic of 0.831. The area under the receiver operating characteristic curve of the new model (0.840, 95% confidence interval: 0.789 - 0.883) was significantly higher than that of the non-invasive scoring systems (all P < 0.05). The calibration plot and Hosmer-Lemeshow test (P = 0.771) showed good calibration accuracy. Kaplan-Meier survival analysis showed that the cumulative survival rate in the high-risk group was significantly lower (P < 0.01). Conclusions: The prognostic nomogram consisting of the Fibrosis-4 index and complications can effectively predict the risk of 3-month mortality in patients with hepatic encephalopathy.
背景:肝性脑病是一种严重的神经精神并发症,伴有肝硬化失代偿,短期死亡率高。目的:本研究旨在评估无创评分系统的预测价值,并开发一种预后图,以确定肝性脑病患者3个月死亡的风险。方法:回顾性分析251例失代偿期肝硬化合并肝性脑病患者的临床资料。使用单变量和多变量logistic回归分析比较幸存者和非幸存者的临床数据和非侵入性评分系统。建立了一个预测模型,并使用自举重采样程序进行了验证。结果:251例患者中,3个月内死亡40例(15.9%)。未存活组并发症发生率较高,无创评分较高(P < 0.01)。多因素分析显示肝肾综合征、自发性细菌性腹膜炎、上消化道出血、纤维化-4指数为独立危险因素。建立了一个包含纤维化-4指数和并发症的新模型,并使用bootstrap校正的C统计量0.831来评估辨别性。新模型的受试者工作特征曲线下面积(0.840,95%可信区间0.789 ~ 0.883)显著高于无创评分系统(均P < 0.05)。校正图和Hosmer-Lemeshow检验(P = 0.771)显示出较好的校正精度。Kaplan-Meier生存分析显示,高危组患者累积生存率显著降低(P < 0.01)。结论:由纤维化-4指数及并发症组成的预后图可有效预测肝性脑病患者3个月死亡风险。

Background: Intrahepatic covalently closed circular DNA (cccDNA) plays a critical role in the life cycle of the hepatitis B virus (HBV). Growing evidence suggests that microRNAs (miRNAs) may regulate cccDNA expression and contribute to the natural history of chronic hepatitis B (CHB). Objectives: This study aimed to investigate potential miRNA-mRNA regulatory axes of intrahepatic cccDNA in CHB-GZ patients and to identify new therapeutic targets. Methods: Thirteen CHB-GZ patients were included and divided into two groups based on cccDNA levels: reference group (n = 7) with cccDNA < 1 copy/cell and control group (n = 6) with cccDNA ≥ 1 copy/cell. Transcriptome-wide miRNA and mRNA expression profiles in liver tissue were determined. Differentially expressed miRNAs (DE-miRNAs) and mRNAs (DE-mRNAs) were defined by |logFC| > log1.5 and P < 0.05. Enrichment analyses of gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were performed. Candidate miRNA-mRNA interaction pairs were acquired from miRTarBase, and a miRNA-mRNA network was constructed using Cytoscape based on the Spearman correlation coefficient (r). Results: We identified 19 DE-miRNAs and 340 DE-mRNAs. The most enriched GO terms were related to biological processes that regulate the virus life cycle, viral process, and viral genome replication. KEGG pathway enrichment analysis suggested that these predicted targets were associated with hepatitis B. Finally, we found a high correlation between miR-4295 and ZNF224, which suggests that they may form a potential regulatory axis of intrahepatic cccDNA in CHB-GZ patients. Conclusions: Our study suggests that miR-4295 and ZNF224 may be the potential regulatory axis of intrahepatic cccDNA in patients with CHB-GZ.
背景:肝内共价闭合环状DNA(cccDNA)在乙型肝炎病毒(HBV)的生命周期中起着至关重要的作用。越来越多的证据表明,微小RNA(miRNA)可能调节cccDNA的表达,并与慢性乙型肝炎(CHB)的自然史有关。目的:本研究旨在研究CHB-GZ患者肝内cccDNA的潜在miRNA mRNA调控轴,并确定新的治疗靶点。方法:13例CHB-GZ患者根据cccDNA水平分为两组:对照组(n=7)cccDNA<1拷贝/细胞,对照组(n=6)cccDNA≥1拷贝/细胞。测定了肝组织中转录组范围的miRNA和mRNA表达谱。差异表达的miRNAs(DE-miRNAs)和mRNAs(DE-mRNAs)由|logFC|>log1.5定义,P<0.05。对基因本体论(GO)和京都基因和基因组百科全书(KEGG)途径进行了富集分析。从miRTarBase中获得候选miRNA-mRNA相互作用对,并使用基于Spearman相关系数(r)的Cytoscape构建miRNA-mRNA网络。结果:我们鉴定了19个DE miRNA和340个DE mRNA。最丰富的GO术语与调节病毒生命周期、病毒过程和病毒基因组复制的生物过程有关。KEGG通路富集分析表明,这些预测的靶点与乙型肝炎有关。最后,我们发现miR-4295和ZNF224之间存在高度相关性,这表明它们可能在CHB-GZ患者中形成肝内cccDNA的潜在调控轴。结论:miR-4295和ZNF224可能是CHB-GZ患者肝内cccDNA的潜在调控轴。

Background: The leading cause of mutations in the hepatitis B virus (HBV) genome is the high rate of nucleotide misincorporation during reverse transcription. Most mutations were found within the “a” determinant of the S gene’s major hydrophilic region (MHR). They resulted in escape mutants due to amino acid changes in the MHR. However, mutations outside the MHR can also trigger escape mutants. Objectives: This study focused on further molecular studies on the MHR of genotype D of HBV DNA isolated from patients with chronic HBV infection, together with the coexistence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibodies (anti-HBs) in their serum samples. Methods: In this study, serum samples from 83 patients with chronic HBV infection were analyzed by serological and immunological tests for the concurrence of HBsAg and anti-HBs. In addition, the mutation in the HBV DNA was assessed by nucleotide sequencing of S genes within, upstream, and downstream of the MHR. Results: Among 83 patients with chronic HBV infection, the coexistence of HBsAg and anti-HBs were detected in 11 (13.25%) individuals. Mutations in eight amino acids of seven samples analyzed for nucleotide sequencing were observed at 27 different sites in three locations, namely upstream, within, and downstream of the MHR. The mutations affected the structure of the epitope and the appearance of an escape mutant. Conclusions: The results indicated that mutations downstream and upstream of the MHR play a role in the coexistence of HBsAg and anti-HBs in patients with chronic HBV infection.
背景:乙型肝炎病毒(HBV)基因组突变的主要原因是逆转录过程中核苷酸错误掺入的高发生率。大多数突变发生在S基因主要亲水区(MHR)的“a”决定因子内。由于MHR中氨基酸的变化,它们导致了逃逸突变体。然而,MHR外的突变也会引发逃逸突变。目的:本研究对慢性HBV感染患者分离的HBV DNA基因D型的MHR以及血清中乙型肝炎表面抗原(HBsAg)和乙型肝炎表面抗体(anti-HBs)共存的情况进行进一步的分子研究。方法:对83例慢性HBV感染患者的血清标本进行血清学和免疫学检查,分析其HBsAg和抗hbs的并发性。此外,通过对MHR内、上游和下游的S基因进行核苷酸测序来评估HBV DNA的突变。结果:83例慢性HBV感染患者中,11例(13.25%)同时检测到HBsAg和anti-HBs。研究人员在MHR上游、内部和下游三个位置的27个不同位点观察到7个样本中8个氨基酸的突变。这些突变影响了表位的结构和逃逸突变体的外观。结论:结果表明,MHR下游和上游的突变在慢性HBV感染患者中HBsAg和anti-HBs共存中起作用。

Most mutations were found within the “a” determinant of the S gene’s major hydrophilic region (MHR). They resulted in escape mutants due to amino acid changes in the MHR. However, mutations outside the MHR can also trigger escape mutants. Objectives: This study focused on further molecular studies on the MHR of genotype D of HBV DNA isolated from patients with chronic HBV infection, together with the coexistence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibodies (anti-HBs) in their serum samples. Methods: In this study, serum samples from 83 patients with chronic HBV infection were analyzed by serological and immunological tests for the concurrence of HBsAg and anti-HBs. In addition, the mutation in the HBV DNA was assessed by nucleotide sequencing of S genes within, upstream, and downstream of the MHR. Results: Among 83 patients with chronic HBV infection, the coexistence of HBsAg and anti-HBs were detected in 11 (13.25%) individuals. Mutations in eight amino acids of seven samples analyzed for nucleotide sequencing were observed at 27 different sites in three locations, namely upstream, within, and downstream of the MHR. The mutations affected the structure of the epitope and the appearance of an escape mutant. Conclusions: The results indicated that mutations downstream and upstream of the MHR play a role in the coexistence of HBsAg and anti-HBs in patients with chronic HBV infection.","PeriodicalId":12895,"journal":{"name":"Hepatitis Monthly","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42275653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
