| 1 | Viral and host causes of fatty liver in chronic hepatitis B显示文摘AIM: To investigate the viral and host causes of fatty liver in chronic hepatitis B patients and the role of fat deposits in liver damage.METHODS: A total of 164 patients (113 males and 51 females, average age 35±11.3 years, and range 10-62 years) with previously untreated chronic hepatitis B were included in the study. The patients were divided into two groups depending on the result of liver biopsy: group without steatosis (100 patients with <5% hepatosteatosis) and group with steatosis (64 patients with >5% hepatosteatosis). The groups were compared in terms of gender, body mass index (BMI), liver enzymes (ALT, AST, ALP, GGT), cholesterol, triglyceride, HBeAg, viral load, and histological findings. In the group with steatosis, the patients were subdivided depending on the degree of steatosis into mild group (45 patients with 5-24% steatosis), and severe group (19 patients with >25% steatosis). RESULTS: In the group of chronic hepatitis B with steatosis, the mean age, BMI, cholesterol, and triglyceride levels were significantly higher than those in the group without steatosis (P<0.05). Steatosis was found in 53 (46.9%) of male patients and 11 (22%) of female patients (P<0.05). No significant difference was found in the positivity of ALT, AST, ALP, GGT, HBeAg, viral load, histological activity index (HAI) and stage between the two groups (P>0.05). In the group with severe steatosis, the BMI was significantly higher than that in the group with mild steatosis (P<0.05). No significant difference was found in the other parameters between the groups (P>0.05). CONCLUSION: Steatosis in chronic hepatitis B appears to be a result of metabolic factors of the host rather than the effect of viruses. Steatosis is unrelated to the HAI and degree of fibrosis, which are considered as the histological indicators of liver damage. | Emin Altiparmak Seyfettin K(o|¨)klü Mesut Yalinkilic Osman Yüksel Bahattin Cicek Ertugrul Kayacetin Tülin Sahin | 2005 | World Journal of Gastroenterology2005，11，20： | 52 |

| 3 | AGNP精神科治疗药物监测共识指南:2011显示文摘治疗药物监测(Therapeutic drug monitoring,TDM),如通过定量测定血清或血浆药物浓度指导用药剂量优化,已经成为对患者进行精神药物治疗的很有价值的工具。在患者用药依从性难以判断、药物耐受性不佳、治疗剂量下无效以及可能存在药代动力学药物-药物相互作用等情况下,测定药物浓度是很有用的。在精神科,有可能明显获益于TDM的主要患者群体包括儿童、孕妇、老年患者、智力障碍患者、涉及司法的患者、已知或怀疑携带药代动力学相关基因变异的患者,以及合并躯体疾病影响药代动力学的患者。然而,只有将TDM充分整合到临床治疗过程中去,才能发挥其优化药物治疗的潜在优势。为了促进TDM的合理应用,神经精神药理学与药物精神病学协会(Arbeitsgemeinschaft für Neuropsychopharmakologie und Pharmakopsychiatrie,AGNP)的TDM专家组在2004年发表了精神药物治疗药物监测指南。之后,随着知识不断更新,又有许多可能需要进行TDM的新药上市。因此,本次更新将神经精神药物的种类扩展到了128种,并将其TDM必要性划分为从'强烈推荐'到'可能有用'的四个等级。经过大量细致且全面的文献检索与分门别类的汇总整理,将基于循证医学理念的'治疗参考浓度范围'和'剂量相关参考浓度范围'呈现给大家。本共识指南引入了'实验室警戒浓度'的新概念,即实验室需要马上告知治疗医生的药物浓度上限。本共识指南还给出了诸如药物作为细胞色素P450酶的底物和抑制剂的性质,代谢物与母药浓度比值的常见范围,以及与结果解释相关的内容,还提供了何时将TDM与遗传药理学检测相结合的建议。遵循本指南,有助于改善许多患者精神药物治疗的效果,特别是那些存在药代动力学异常的患者。TDM是一门交叉学科,有时针对看起来不一致的数据,需要多学科坦诚地讨论,只有这样,患者才能从这种合作中获益。 | Hiemke C Baumann P Bergemann N Conca A Dietmaier O Egberts K Fric M Gerlach M Greiner C Gründer G Haen E Havemann-Reinecke U Jaquenoud Sirot E Kirchherr H Laux G Lutz UC Messer T Müller MJ Pfuhlmann B Rambeck B Riederer P Schoppek B Stingl J Uhr M Ulrich S Waschgler R Zernig G 李文标(译) 果伟(译) 阮灿军(译) 贺静(译) 汤宜朗(审校) 王传跃(审校) | 2016 | 实用药物与临床2016，19，10： | 37 |

| 5 | Achalasia: A review of clinical diagnosis, epidemiology,treatment and outcomes显示文摘Achalasia is a neurodegenerative motility disorder of the oesophagus resulting in deranged oesophageal peristalsis and loss of lower oesophageal sphincter function.Historically,annual achalasia incidence rates were believed to be low,approximately 0.5-1.2 per 100000.More recent reports suggest that annual incidence rates have risen to 1.6 per 100000 in some populations.The aetiology of achalasia is still unclear but is likely to be multi-factorial.Suggested causes include environmental or viral exposures resulting in inflammation of the oesophageal myenteric plexus,which elicits an autoimmune response.Risk of achalasia may be elevated in a sub-group of genetically susceptible people.Improvement in the diagnosis of achalasia,through the introduction of high resolution manometry with pressure topography plotting,has resulted in the development of a novel classification system for achalasia.This classification system can evaluate patient prognosis and predict responsiveness to treatment.There is currently much debate over whether pneumatic dilatation is a superior method compared to the Heller’s myotomy procedure in the treatment of achalasia.A recent com-parative study found equal efficacy,suggesting that patient preference and local expertise should guide the choice.Although achalasia is a relatively rare condition,it carries a risk of complications,including aspiration pneumonia and oesophageal cancer.The risk of both squamous cell carcinoma and adenocarcinoma of the oesophagus is believed to be significantly increased in patients with achalasia,however the absolute excess risk is small.Therefore,it is currently unknown whether a surveillance programme in achalasia patients would be effective or cost-effective. | Orla M O'Neill Brian T Johnston Helen G Coleman | 2013 | World Journal of Gastroenterology2013，19，35： | 26 |

| 7 | Role of liver transplantation in the management of hepatoblastoma in the pediatric population显示文摘Hepatoblastoma(HB) is the most common primary liver tumor in children and accounts for two-thirds of all malignant liver neoplasms in the pediatric population. For patients with advanced HB(unresectable or unresponsive to chemotherapy), combined treatment with chemotherapy and liver transplantation is an excellent option. The etiology of HB is mostly obscure because of its extreme rarity although some inherited syndromes and very low birth weight have been associated with it. The prognosis for children with HB has significantly improved in the past three decades thanks to advancements in chemotherapy, surgical resection and postoperative care. In 2002 a surgical staging system called pretreatment extent of disease(PRETEXT) was designed to allow a universal, multidisciplinary approach to patients with HB. Between one-third to two-thirds of patients initially present with unresectable tumors or distant metastases, but up to 85% of these tumors become operable after neoadjuvant chemotherapy. Patients with PRETEXT categories 1, 2, and some 3 are referred for neoadjuvant chemotherapy followed by surgical resection with the goal of complete tumor removal. Classic treatments regimens include a combination of cisplatin, fluorouracil, and vincristine or cisplatin and doxorubicin. Liver transplantation is the only treatment option for unresectable HB. In 2010 the pediatric end-stage liver disease, a pediatric-specific scoring system that determines a patient's ranking on the liver transplant list, began to award additional 'exception' points for patients with HB. We analyzed the Standard Transplant Analysis and Research dataset to assess the impact of changes in exception point criteria for HB on outcomes after liver transplantation at Texas Children's Hospital in Houston, Texas. We found that patients who were listed for transplantation with current HB exception criteria experienced a shorter waitlist time but survival was similar between the two eras. | Saira Khaderi Jacfranz Guiteau Ronald T Cotton Christine O'Mahony Abbas Rana John A Goss | 2014 | World Journal of Transplantation2014，4，4： | 23 |
| 8 | Mechanisms of hepatocellular carcinoma progression显示文摘Hepatocellular carcinoma(HCC) is the most common primary malignancy of the liver. It is the second leading cause of cancer-related deaths worldwide, with a very poor prognosis. In the United States, there has been only minimal improvement in the prognosis for HCC patients over the past 15 years. Details of the molecular mechanisms and other mechanisms of HCC progression remain unclear. Consequently, there is an urgent need for better understanding of these mechanisms. HCC is often diagnosed at advanced stages, and most patients will therefore need systemic therapy, with sorafenib being the most common at the present time. However, sorafenib therapy only minimally enhances patient survival. This review provides a summary of some of the known mechanisms that either cause HCC or contribute to its progression. Included in this review are the roles of viral hepatitis, non-viral hepatitis, chronic alcohol intake, genetic predisposition and congenital abnormalities, toxic exposures, and autoimmune diseases of the liver. Well-established molecular mechanisms of HCC progression such as epithelial-mesenchymal transition, tumor-stromal interactions and the tumor microenvironment, cancer stem cells, and senescence bypass are also discussed. Additionally, we discuss the roles of circulating tumor cells,immunomodulation, and neural regulation as potential new mechanisms of HCC progression. A better understanding of these mechanisms could have implications for the development of novel and more effective therapeutic and prognostic strategies, which are critically needed. | Olorunseun O Ogunwobi Trisheena Harricharran Jeannette Huaman Anna Galuza Oluwatoyin Odumuwagun Yin Tan Grace X Ma Minhhuyen T Nguyen | 2019 | World Journal of Gastroenterology2019，25，19： | 21 |

| 14 | Probiotic bacteria change Escherichia coli-induced gene expression in cultured colonocytes:Implications in intestinal pathophysiology显示文摘AIM: To investigate the change in eukaryotic gene expression profile in Caco-2 cells after infection with strains of Escherichia coli and commensal probiotic bacteria. METHODS: A 19 200 gene/expressed sequence tag gene chip was used to examine expression of genes after infection of Caco-2 cells with strains of normal flora E. coli,Lactobacillus plantarum,and a combination of the two. RESULTS: The cDNA microarray revealed up-regulation of 155 and down-regulation of 177 genes by E. coli . L. plantarum up-regulated 45 and down-regulated 36 genes. During mixed infection,27 genes were up-regulated and 59 were down-regulated,with nullification of stimulatory/inhibitory effects on most of the genes. Expression of several new genes was noted in this group. CONCLUSION: The commensal bacterial strains used in this study induced the expression of a large number of genes in colonocyte-like cultured cells and changed the expression of several genes involved in important cellular processes such as regulation of transcription,protein biosynthesis,metabolism,cell adhesion,ubiquitination,and apoptosis. Such changes induced by the presence of probiotic bacteria may shape the physiologic and pathologic responses they trigger in the host. | Pinaki Panigrahi Gheorghe T Braileanu Hegang Chen O Colin Stine | 2007 | World Journal of Gastroenterology2007，13，47： | 10 |

| 17 | 在结肠和直肠的癌症的淋巴节点收获: 当前的考虑显示文摘 The prognostic significance of identifying lymph node(LN) metastases following surgical resection for colon and rectal cancer is well recognized and is reflected in accurate staging of the disease.An established body of evidence exists,demonstrating an association between a higher total LN count and improved survival,particularly for node negative colon cancer.In node positive disease,however,the lymph node ratios may represent a better prognostic indicator,although the impact of this on clinical treatment has yet to be universally established.By extension,strategies to increase surgical node harvest and/or laboratory methods to increase LN yield seem logical and might improve cancer staging.However,debate prevails as to whether or not these extrapolations are clinically relevant,particularly when very high LN counts are sought.Current guidelines recommend a minimum of 12 nodes harvested as the standard of care,yet the evidence for such is questionable as it is unclear whether an increasing the LN count results in improved survival.Findings from modern treatments,including down-staging in rectal cancer using pre-operative chemoradiotherapy,paradoxically suggest that lower LN count,or indeed complete absence of LNs,are associated with improved survival;implying that using a specific number of LNs harvested as a measure of surgical quality is not always appropriate.The pursuit of a sufficient LN harvest represents good clinical practice;however,recent evidence shows that the exhaustive searching for very high LN yields may be unnecessary and has little in? uence on modern approaches to treatment. | James R McDonald Andrew G Renehan Sarah T O’Dwyer Najib Y Haboubi | 2012 | World Journal of Gastrointestinal Surgery2012，4，1： | 8 |
