| 1 | Chronic hepatitis C and liver fibrosis显示文摘Chronic infection with hepatitis C virus(HCV) is a leading cause of liver-related morbidity and mortality worldwide and predisposes to liver fibrosis and endstage liver complications. Liver fibrosis is the excessive accumulation of extracellular matrix proteins, including collagen, and is considered as a wound healing response to chronic liver injury. Its staging is critical for the management and prognosis of chronic hepatitis C(CHC) patients, whose number is expected to rise over the next decades, posing a major health care challenge. This review provides a brief update on HCV epidemiology, summarizes basic mechanistic concepts of HCV-dependent liver fibrogenesis, and discusses meth-ods for assessment of liver fibrosis that are routinely used in clinical practice. Liver biopsy was until recently considered as the gold standard to diagnose and stage liver fibrosis. However, its invasiveness and drawbacks led to the development of non-invasive methods, which include serum biomarkers, transient elastography and combination algorithms. Clinical studies with CHC patients demonstrated that non-invasive methods are in most cases accurate for diagnosis and for monitoring liver disease complications. Moreover, they have a high prognostic value and are cost-effective. Non-invasive methods for assessment of liver fibrosis are gradually being incorporated into new guidelines and are becoming standard of care, which significantly reduces the need for liver biopsy. | Giada Sebastiani Konstantinos Gkouvatsos Kostas Pantopoulos | 2014 | World Journal of Gastroenterology2014，20，32： | 19 |

| 3 | 弹性成像定量分析对自身免疫性肝病的诊断价值显示文摘目的:自身免疫性肝病的发病机理至今尚未明确,与多种疾病之间存在着联系,临床诊断具有一定的难度。本研究利用超声弹性成像技术定量分析自身免疫性肝病的病理特征,探讨该技术的诊断价值,为自身免疫性疾病的治疗提供诊断依据。方法:选取我院2011年3月-2013年6月收治的自身免疫性肝病患者182例,随机分为观察组和对照组。观察组98例患者采用弹性成像定量分析的方法进行诊断,对照组84例则采用常规病理学诊断。观察并比较两组患者的诊断准确率及诊断耗时。结果:观察组检出94例,诊断率为95.92%;对照组检出81例,诊断率为96.43%,两组诊断准确率比较无明显差异(P>0.05)。观察组平均诊断耗时为5.6 h;对照组平均诊断耗时为11.6 h,观察组诊断时间比对照组短,差异具有统计学意义(P<0.05)。结论:弹性成像定量分析对自身免疫性肝病的诊断准确率与病理活检诊断具有较好的一致性,且诊断耗时短、患者依从性好,值得在临床中进一步推广应用以辅助病理诊断,避免误诊或漏诊现象发生。 | 周艳贤 陈敏 董晓宇 郭晓东 冯松 杨美 冯卉 刘洋 | 2014 | 现代生物医学进展2014，14，11： | 1 |
| 4 | Telaprevir- and boceprevir-based tritherapies in real practice for F3-F4 pretreated hepatitis C virus patients显示文摘AIM:To assess,in a routine practice setting,the sus-tained virologic response(SVR) to telaprevir(TPV) or boceprevir(BOC) in hepatitis C virus(HCV) nullresponders or relapsers with severe liver fibrosis.METHODS:One hundred twenty-five patients were treated prospectively for 48 wk with TPV or BOC + pegylated-interferon(peg-INF) α2a + ribavirin(PR) according to standard treatment schedules without randomization.These patients were treated in routine practice settings in 10 public or private health care centers,and the data were prospectively collected.Only patients with severe liver fibrosis(Metavir scores of F3 or F4 upon liver biopsy or liver stiffness assessed by elastography),genotype 1 HCV and who were null-responders or relapsers to prior PR combination therapy were included in this study.RESULTS:The Metavir fibrosis scores were F3 in 35(28%) and F4 in 90(72%) of the patients.In total,62.9% of the patients were null-responders and 37.1% relapsers to the previous PR therapy.The overall SVR rate at 24 wk post-treatment withdrawal was 59.8%.The SVR was 65.9% in the TPV group and 44.1% in the BOC group.Independent predictive factors of an SVR included a response to previous treatment,relapsers vs null-responders [OR = 3.9;(1.4,10.6),P = 0.0084],a rapid virological response(RVR) [OR 6.9(2.6,18.2),P = 0.001] and liver stiffness lower than 21.3 kPa [OR = 8.2(2.3,29.5),P = 0.001].During treatment,63 patients(50.8%) had at least one severe adverse event(SAE) of grade 3 or 4.A multivariate analysis identified two factors associated with SAEs:female gender [OR = 2.4(1.1,5.6),P = 0.037] and a platelet count below 150 × 103/ mm3 [OR = 5.3(2.3,12.4),P ≤ 0.001].CONCLUSION:More than half of these difficult-to-treat patients achieved an SVR and had SAEs in an actual practice setting.The SVR rate was influenced by the response to previous PR treatment,the RVR and liver stiffness. | Delphine Bonnet Matthieu Guivarch Anais Palacin Laurent Alric Emilie Bérard Jean-Marc Combis Andre Jean Remy Andre Glibert Jean-Louis Payen Sophie Metivier Karl Barange Herve Desmorat Florence Nicot Florence Abravanel | 2014 | World Journal of Hepatology2014，6，9： | 1 |
