2Molecular mechanism of hepatitis B virus X protein function in hepatocarcinogenesis显示文摘Many factors are considered to contribute to hepatitis B virus(HBV)-associated hepatocellular carcinoma(HCC),including products of HBV,HBV integration and mutation,and host susceptibility. HBV X protein(HBx) can interfere with several signaling pathways associated with cell proliferation and invasion,and HBx C-terminal truncation has been suggested to impact the development of HCC. This review focuses on the pathological functions of HBx in HBV-induced hepatocarcinogenesis. As a transactivator,HBx can affect regulatory non-coding RNAs(nc RNAs),including micro RNAs and long nc RNAs. HBx is also involved in epigenetic modification and DNA repair. HBx interacts with various signal-transduction pathways,such as the p53,Wnt,and nuclear factor-κB pathways. We conclude that HBx hastens the development of hepatoma.Ming Geng Xuan Xin Li-Quan Bi Lu-Ting Zhou Xiao-Hong Liu 2015World Journal of Gastroenterology2015,21,38:24
3High levels of serum interleukin-6 increase mortality of hepatitis B virus-associated acute-on-chronic liver failure显示文摘BACKGROUND Patients with hepatitis B virus-associated acute-on-chronic liver failure(HBVACLF)present a complex and poor prognosis.Systemic inflammation plays an important role in its pathogenesis,and interleukin-6(IL-6)as a pro-inflammatory cytokine is related with severe liver impairment and also plays a role in promoting liver regeneration.Whether serum IL-6 influences HBV-ACLF prognosis has not been studied.AIM To determine the impact of serum IL-6 on outcome of patients with HBV-ACLF.METHODS We performed a retrospective study of 412 HBV-ACLF patients.The findings were analyzed with regard to mortality and the serum IL-6 level at baseline,as well as dynamic changes of serum IL-6 within 4 wk.RESULTS The serum IL-6 level was associated with mortality.Within 4 wk,deceased patients had significantly higher levels of IL-6 at baseline than surviving patients[17.9(7.3-57.6)vs 10.4(4.7-22.3),P=0.011].Patients with high IL-6 levels(>11.8 pg/mL)had a higher mortality within 4 wk than those with low IL-6 levels(≤11.8 pg/mL)(24.2%vs 13.2%,P=0.004).The odds ratios calculated using univariate and multivariate logistic regression were 2.10(95%confidence interval[CI]:1.26-3.51,P=0.005)and 2.11(95%CI:1.15-3.90,P=0.017),respectively.The mortality between weeks 5 and 8 in patients with high IL-6 levels at 4 wk was 15.0%,which was significantly higher than the 6.6%mortality rate in patients with low IL-6 levels at 4 wk(hazard ratio=2.39,95%CI:1.05-5.41,P=0.037).The mortality was 5.0%in patients with high IL-6 levels at baseline and low IL-6 levels at 4 wk,7.5%in patients with low IL-6 levels both at baseline and at 4 wk,11.5%in patients with low IL-6 levels at baseline and high IL-6 levels at 4 wk,and 16.7%in patients with high IL-6 levels both at baseline and at 4 wk.The increasing trend of the mortality rate with the dynamic changes of IL-6 was significant(P for trend=0.023).CONCLUSION A high level of serum IL-6 is an independent risk factor for mortality in patients with HBV-ACLF.Furthermore,a sustained high level or dynamic elevated level of serum IL-6 indicates a higher mortality.Chao Zhou Ning Zhang Ting-Ting He Yao Wang Li-Fu Wang Yong-Qiang Sun Jing Jing Jing-Jing Zhang Shuang-Nan Fu Xuan Wang Xiao-Xiao Liang Xin Li Man Gong Jun Li 2020World Journal of Gastroenterology2020,26,30:15
4Antioxidant and Anti-inflammatory Capacity of Ferulic Acid Released from Wheat Bran by Solid-state Fermentation of Aspergillus niger显示文摘Objective A strain of Aspergillus niger(A. niger), capable of releasing bound phenolic acids from wheat bran, was isolated. This strain was identified by gene sequence identification. The antioxidant and anti-inflammatory capacity of ferulic acid released from wheat bran by this A. niger strain(FA-WB) were evaluated. Methods Molecular identification techniques based on PCR analysis of specific genomic sequences were conducted; antioxidant ability was examined using oxygen radical absorbance capacity(ORAC), cellular antioxidant activity(CAA) assays, and erythrocyte hemolysis assays. RAW264.7 cells were used as a model to detect anti-inflammatory activity. Results The filamentous fungal isolate was identified to be A. niger. ORAC and CAA assay showed that FA-WB had better antioxidant activity than that of the ferulic acid standard. The erythrocyte hemolysis assay results suggested that FA-WB could attenuate AAPH-induced oxidative stress through inhibition of reactive oxy gen species(ROS) generation. FA-WB could significantly restore the AAPH-induced increase in intracellular antioxidant enzyme activities to normal levels as well as inhibit the intracellular malondialdehyde formation. TNF-?, IL-6, and NO levels indicated that FA-WB can inhibit the inflammation induced by lipopolysaccharide(LPS). Conclusion Ferulic acid released from wheat bran by a new strain of A. niger had good anti-inflammatory activity and better antioxidant ability than standard ferulic acid.YIN Zhi Na WU Wen Jia SUN Chong Zhen LIU Hui Fan CHEN Wen Bo ZHAN Qi Ping LEI Zhuo Gui XIN Xuan MA Juan Juan YAO Kun MIN Tian ZHANG Meng Meng WU Hui 2019Biomedical and Environmental Sciences2019,32,1:14

6Ultrathin Al2O3-coated reduced graphene oxide membrane for stable lithium metal anode显示文摘Lithium(Li) metal has been considered as the most attractive anode materials for Li-ion batteries(LIBs)due to its high theoretic specific capacity. The formation of unstable solid electrolyte interphase(SEI) and dendritic Li on the metal anode, however, hindered its practical application. Herein, to address the issues, a Li-free electrode with ultrathin Al_2O_3 coated on reduced graphene oxide(rGO) membrane that covers a Cu foil current collector was developed. The composite electrode exhibits excellent interfacial protection of lithium metal deposited between Cu foil and rGO electrochemically. Firstly, it affords good Li^+ permeability from the electrolyte. Secondly, the ultrathin Al_2O_3 has sufficient mechanical strength to inhibit the penetration of Li dendrite. Li metal was observed uniformly deposited between rGO membrane and Cu collector, and stable cycle performance of Li plating/stripping with Coulombic efficiency of ~91.75% at the 100 th cycle is achieved in organic carbonate electrolyte without any additives.Fan Zhang Fei Shen ZhaoYang Fan Xin Ji Bin Zhao ZhouTing Sun YingYing Xuan XiaoGang Han 2018Rare Metals2018,37,6:11
7Association between the presence of H pylori in the liver and hepatocellular carcinoma: A meta-analysis显示文摘AIM: To evaluate the arguments for and against the possible roles of H pylori in hepatocellular carcinoma (HCC). METHODS: We performed a systematic review of all relevant studies published in the literature. A total of 103 clinical trials and reports were identified, but only 10 trials qualified under our selection criteria. A meta-analysis was carried out by a biostatistician according to the Cochrane Reviewers’ Handbook recommended by The Cochrane Collaboration.RESULTS: Nine case-control studies and one retrospective cross sectional study were included in the final analysis. Overall the prevalence of H pylori infection was 53.3% (129 of 242) in cases and 10.4% (29 of 280) in controls, and the summary odds ratio for the association of H pylori infection with the risk for HCC (using the fixed-effects model, which accounted for the homogeneity across the 10 studies) was determined to be 13.63 (95% CI, 7.90-23.49).CONCLUSION: Our analysis showed a positive association between H pylori infection and the risk of HCC, with an indication of possible publication bias and possible confounders due to study designs that showed results of less pronounced associations.Shi-Ying Xuan Yong-Ning Xin An-Jin Chen Quan-Jiang Dong Xin Qiang Ning Li Ming-Hua Zheng Hua-Shi Guan 2008World Journal of Gastroenterology2008,14,2:10

15Multi-center Study of Enteral Feeding Practices in Hospitalized Late Preterm Infants in China显示文摘Objective To investigate the current enteral feeding practices in hospitalized late preterm infants in the Beijing area of China. Methods A multi-center, cross-sectional study was conducted. Infants born after 34 weeks and before 37 weeks of gestation were enrolled from 25 hospitals in the Beijing area of China from October 2015 to October 2017. Data on enteral feeding practices were collected and analyzed. Results A total of 1,463 late preterm infants were enrolled, with a mean gestational age(GA) of 35.6(34.9, 36.1) weeks. The percentage of exclusive breastfeeding was 4.5% at the initiation of enteral feeding but increased to 14.4% at discharge. When human milk was not available, most infants(46.1%) were fed with preterm infant formula. The rate of exclusive human milk feeding in infants born at 34 weeks gestation was higher than at discharge(21.1% of infants born at 34 weeks' GA versus 12.1% of infants born at 35 weeks' GA versus 12.3% of infants born at 36 weeks' GA, P < 0.001). Only 28.4% of late preterm infants achieved full enteral feeding at discharge, and only 19.2% achieved 120 kcal/(kg·d) by enteral feeding at discharge. Importantly, 40.5% of infants did not regain the birth weight at discharge. Conclusion Enteral feeding support of late preterm infants has not been standardized to achieve optimal growth. Moreover, the human milk feeding rate was low, and many late preterm infants did not achieve the goal of enteral feeding and failed to regain birth weight at the time of discharge. More aggressive enteral feedings protocols are needed to promote human milk feeding and optimize growth for late preterm infants.QUAN Mei Ying LI Zheng Hong WANG Dan Hua SCHIBLER Kurt YANG Li LIU Jie QIN Xuan Guang ZHANG Xin HAN Tong Yan ZHANG Wei 2018Biomedical and Environmental Sciences2018,31,7:6
16PNPLA3 I148M variant in nonalcoholic fatty liver disease:Demographic and ethnic characteristics and the role of the variant in nonalcoholic fatty liver fibrosis显示文摘Patatin-like phospholipase domain-containing 3(PNPLA3 or adiponutrin) displays anabolic and catabolic activities in lipid metabolism,and has been reported to be significantly associated with liver fat content.Variousstudies have established a strong link between the 148 isoleucine to methionine protein variant(I148M) of PNPLA3 and liver diseases,including nonalcoholic fatty liver disease(NAFLD).However,detailed demographic and ethnic characteristics of the I148 M variant and its role in the development of nonalcoholic fatty liver fibrosis have not been fully elucidated.The present review summarizes the current knowledge on the association between the PNPLA3 I148 M variant and NAFLD,and especially its role in the development of nonalcoholic fatty liver fibrosis.First,we analyze the impact of demographic and ethnic characteristics of the PNPLA3 I148 M variant and the presence of metabolic syndrome on the association between PNPLA3 I148 M and NAFLD.Then,we explore the role of the PNPLA3 I148 M in the development of nonalcoholic fatty liver fibrosis,and hypothesize the underlying mechanisms by speculating a pro-fibrogenic network.Finally,we briefly highlight future research that may elucidate the specific mechanisms of the PNPLA3 I148 M variant in fibrogenesis,which,in turn,provides a theoretical foundation and valuable experimental data for the clinical management of nonalcoholic fatty liver fibrosis.Li-Zhen Chen Yong-Ning Xin Ning Geng Man Jiang Ding-Ding Zhang Shi-Ying Xuan 2015World Journal of Gastroenterology2015,21,3:6
17Differences in clinical features of Crohn's disease and intestinal tuberculosis显示文摘AIM: To investigate the clinical features of Crohn's disease(CD) and intestinal tuberculosis(ITB) with a scoring system that we have developed.METHODS: A total of 25 CD and 40 ITB patients were prospectively enrolled from August 2011 to July 2012.Their characteristics and clinical features were recorded. Laboratory, endoscopic, histologic and radiographic features were determined. The features with a high specificity were selected to establish a scoring system. The features supporting CD scored +1, and those supporting ITB scored-1; each patient received a final total score. A receiver operating characteristic(ROC) curve was used to determine the best cut-off value for distinguishing CD from ITB.RESULTS: Based on a high specificity of differentiating between CD and ITB, 12 features, including longitudinal ulcers, nodular hyperplasia, cobblestone-like mucosa, intestinal diseases, intestinal fistula, the target sign, the comb sign, night sweats, the purified protein derivative test, the interferon-γ release assay(T-SPOT.TB), ring ulcers and ulcer scars, were selected for the scoring system. The results showed that the average total score of the CD group was 3.12 ± 1.740, the average total score of the ITB group was-2.58 ± 0.984, the best cutoff value for the ROC curve was-0.5, and the diagnostic area under the curve was 0.997, which was statistically significant(P < 0.001). The patients whose total scores were higher than-0.5 were diagnosed with CD; otherwise, patients were diagnosed with ITB. Overall, the diagnostic accuracy rate and misdiagnosis rate of this scoring system were 97% and 3%, respectively. CONCLUSION: Some clinical features are valuable for CD and ITB diagnosis. The described scoring system is key to differentiating between CD and ITB.Xin Huang Wang-Di Liao Chen Yu Yi Tu Xiao-Lin Pan You-Xiang Chen Nong-Hua Lv Xuan Zhu 2015World Journal of Gastroenterology2015,21,12:6
18Glutamate Impairs Mitochondria Aerobic Respiration Capacity and Enhances Glycolysis in Cultured Rat Astrocytes显示文摘Objective To study the effect of glutamate on metabolism, shifts in glycolysis and lactate release in rat astrocytes. Methods After 10 days, secondary cultured astrocytes were treated with 1 mmol/L glutamate for 1 h, and the oxygen consumption rates(OCR) and extra cellular acidification rate(ECAR) was analyzed using a Seahorse XF 24 Extracellular Flux Analyzer. Cell viability was then evaluated by MTT assay. Moreover, changes in extracellular lactate concentration induced by glutamate were tested with a lactate detection kit. Results Compared with the control group, treatment with 1 mmol/L glutamate decreased the astrocytes' maximal respiration and spare respiratory capacity but increased their glycolytic capacity and glycolytic reserve. Further analysis found that 1-h treatment with different concentrations of glutamate(0.1-1 mmol/L) increased lactate release from astrocytes, however the cell viability was not affected by the glutamate treatment. Conclusion The current study provided direct evidence that exogenous glutamate treatment impaired the mitochondrial respiration capacity of astrocytes and enhanced aerobic glycolysis, which could be involved in glutamate injury or protection mechanisms in response to neurological disorders.YAN Xu SHI Zhong Fang XU Li Xin LI Jia Xin WU Min WANG Xiao Xuan JIA Mei DONG Li Ping YANG Shao Hua YUAN Fang 2017Biomedical and Environmental Sciences2017,30,1:6
19A three-microRNA panel in serum as novel biomarker for papillary thyroid carcinoma diagnosis显示文摘Background:Accumulating evidence has revealed that circulating microRNAs(miRNAs)can serve as non-invasive biomarkers for cancer diagnosis.This study aimed to identify differentially expressed miRNAs in serum which might become potential biomarkers for non-invasive diagnosis of papillary thyroid carcinoma(PTC).Methods:The experiment was carried out between 2015 and 2017.In the screening stage,the Exiqon miRNA quantitative real-time polymerase chain reaction(qPCR)panel was applied to select candidate miRNAs.In the following training,testing,and external validation stages,the serum samples of 100 patients and 96 healthy controls(HCs)were analyzed to compare the expression levels of the identified miRNAs.The areas under the receiver operating characteristic curves(AUCs)were calculated to assess the diagnostic value of the identified signature.Results:Three miRNAs(miR-25-3p,miR-296-5p,and miR-92a-3p)in serum were consistently up-regulated in PTC patients compared with HCs.A three-miRNA panel was constructed by logistic regression analysis and showed better diagnostic performance than a single miRNA for PTC detection.The AUCs of the panel were 0.727,0.771,and 0.862 for the training,testing,and external validation stage,respectively.Meanwhile,the panel showed stable capability in differentiating PTC patients from patients with benign goiters,with an AUC as high as 0.969.For further exploration,the three identified miRNAs were analyzed in tissue samples(23 PTC vs.23 HCs)and serum-derived exosomes samples(24 PTC vs.24 HCs),and the altered expression in the tumor also indicated their close relationship with PTC disease.Conclusion:We identify a three-miRNA panel in serum which might serve as a promising biomarker for PTC diagnosis.Xuan Zou Feng Gao Zhi-Yan Wang Huo Zhang Qing-Xie Liu Lin Jiang Xin Zhou Wei Zhu 2020Chinese Medical Journal2020,,21:6
