| 2 | Management of pancreatic fluid collections: A comprehensive review of the literature显示文摘Pancreatic fluid collections(PFCs) are a frequent complication of pancreatitis. It is important to classify PFCs to guide management. The revised Atlanta criteria classifies PFCs as acute or chronic, with chronic fluid collections subdivided into pseudocysts and walled-off pancreatic necrosis(WOPN). Establishing adequate nutritional support is an essential step in the management of PFCs. Early attempts at oral feeding can be trialed in patients with mild pancreatitis. Enteral feeding should be implemented in patients with moderate to severe pancreatitis. Jejunal feeding remains the preferred route of enteral nutrition. Symptomatic PFCs require drainage; options include surgical, percutaneous, or endoscopic approaches. With the advent of newer and more advanced endoscopic tools and expertise, and an associated reduction in health care costs, minimally invasive endoscopic drainage has become the preferable approach. An endoscopic ultrasonography-guided approach using a seldinger technique is the preferred endoscopic approach. Both plastic stents and metal stents are efficacious and safe; however, metal stents may offer an advantage, especially in infected pseudocysts and in WOPN. Direct endoscopic necrosectomy is often required in WOPN. Lumen apposing metal stents that allow for direct endoscopic necrosectomy and debridement through the stent lumen are preferred in these patients. Endoscopic retrograde cholangio pancreatography with pancreatic duct(PD) exploration should be performed concurrent to PFC drainage. PD disruption is associated with an increased severity of pancreatitis, an increased risk of recurrent attacks of pancreatitis and long-term complications, and a decreased rate of PFC resolution after drainage. Any pancreatic ductal disruption should be bridged with endoscopic stenting. | Amy Tyberg Kunal Karia Moamen Gabr Amit Desai Rushabh Doshi Monica Gaidhane Reem Z Sharaiha Michel Kahaleh | 2016 | World Journal of Gastroenterology2016，22，7： | 15 |
| 3 | Real time endoscopic ultrasound elastography and strain ratio in the diagnosis of solid pancreatic lesions显示文摘AIM To evaluate the accuracy of the elastography score combined to the strain ratio in the diagnosis of solid pancreatic lesions(SPL). METHODS A total of 172 patients with SPL identified by endoscopic ultrasound were enrolled in the study to evaluate the efficacy of elastography and strain ratio in differentiating malignant from benign lesions. The semi quantitative score of elastography was represented by the strain ratio method. Two areas were selected, area(A) representing the region of interest and area(B) representing the normal area. Area(B) was then divided by area(A). Sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV), and accuracy were calculated by comparing diagnoses made by elastography, strain ratio and final diagnoses.RESULTS SPL were shown to be benign in 49 patients and malignant in 123 patients. Elastography alone had a sensitivity of 99%, a specificity of 63%, and an accuracy of 88%, a PPV of 87% and an NPV of 96%. The best cut-off level of strain ratio to obtain the maximal area under the curve was 7.8 with a sensitivity of 92%, specificity of 77%, PPV of 91%, NPV of 80% and an accuracy of 88%. Another estimated cut off strain ratio level of 3.8 had a higher sensitivity of 99% and NPV of 96%, but with less specificity, PPV and accuracy 53%, 84% and 86%, respectively. Adding both elastography to strain ratio resulted in a sensitivity of 98%, specificity of 77%, PPV of 91%, NPV of 95% and accuracy of 92% for the diagnosis of SPL. CONCLUSION Combining elastography to strain ratio increases the accuracy of the differentiation of benign from malignant SPL. | Hussein Okasha Shaimaa Elkholy Ramy El-Sayed Mohamed-Naguib Wifi Mohamed El-Nady Walid El-Nabawi Waleed A El-Dayem Mohamed I Radwan Ali Farag Yahya El-sherif Emad Al-Gemeie Ahmed Salman Mohamed El-Sherbiny Ahmed El-Mazny Reem E Mahdy | 2017 | World Journal of Gastroenterology2017，23，32： | 11 |
| 4 | Hepato-cardiac disorders显示文摘Understanding the mutual relationship between the liver and the heart is important for both hepatologists and cardiologists. Hepato-cardiac diseases can be classified into heart diseases affecting the liver, liver diseases affecting the heart, and conditions affecting the heart and the liver at the same time. Differential diagnoses of liver injury are extremely important in a cardiologist's clinical practice calling for collaboration between cardiologists and hepatologists due to the many other diseases that can affect the liver and mimic haemodynamic injury. Acute and chronic heart failure may lead to acute ischemic hepatitis or chronic congestive hepatopathy. Treatment in these cases should be directed to the primary heart disease. In patients with advanced liver disease, cirrhotic cardiomyopathy may develop including hemodynamic changes, diastolic and systolic dysfunctions, reduced cardiac performance and electrophysiological abnormalities. Cardiac evaluation is important for patients with liver diseases especially before and after liver transplantation. Liver transplantation may lead to the improvement of all cardiac changes and the reversal of cirrhotic cardiomyopathy. There are systemic diseases that may affect both the liver and the heart concomitantly including congenital, metabolic and inflammatory diseases as well as alcoholism.

| 5 | Development of an Arabic version of the National Eye Institute Visual Function Questionnaire as a tool to study eye diseases patients in Egypt显示文摘AIM:To develop and test an Arabic version of the National Eye Institute Visual Function Questionnaire-25(NEI-VFQ-25).METHODS:NEI-VFQ-25 was translated into Arabic according to WHO translation guidelines. We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using STATA.RESULTS:We recruited 379 patients, whose mean age was(54.5±15)y. Of 46.2% were males, 227 had cataract,31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version(ARB-VFQ-25) were calculated. Internal consistency was high in all subscales(except general health), with Cronbach-α ranging from0.702-0.911. Test-retest reliability was high(intraclass correlation coefficient 0.79).CONCLUSION:RB-VFQ-25 isareliableandvalidtool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination. | Nizar Saleh Abdelfattah Mohamed Amgad Ahmed A Salama Marina E Israel Ghada A Elhawary Ahmed E Radwan Mohamed M Elgayar Tamer M EL Nakhal Islam T Elkhateb Heba A Hashem Doha K Embaby Amira A Elabd Reem K Elwy Magdi S Yacoub Hamdy Salem Mohamed Abdel-Baqy Ahmad Kassem | 2014 | International Journal of Ophthalmology(English edition)2014，7，5： | 8 |
| 6 | Underactive bladder:Pathophysiology and clinical significance显示文摘Underactive bladder(UAB)is a voiding disorder which generates disabling lower urinary tract symptoms(LUTS)due to the inability to produce an effective voiding contraction sufficient to empty the bladder.The underlying abnormality,that is usually appreciated when performing urodynamic studies,has been defined by the International Continence Society(ICS)as detrusor underactivity(DUA).DUA is a common yet under-researched bladder dysfunction.The prevalence of DUA in different patient groups suggests that multiple aetiologies are implicated.Currently there is no effective therapeutic approach to treat this condition.An improved understanding of the underlying mechanisms is needed to facilitate the development of new advances in treatment.The purpose of this review is to discuss the epidemiology,pathophysiology,common causes and risk factors potentially leading to DUA;to aid in the appropriate diagnosis of DUA to potentially improve treatment outcomes. | Reem Aldamanhori Nadir I.Osman Christopher R.Chapple | 2018 | Asian Journal of Urology2018，5，1： | 7 |
| 7 | 钠-葡萄糖共转运蛋白-2抑制剂或胰高血糖素样肽-1受体激动剂治疗成人2型糖尿病:临床实践指南显示文摘临床问题对于存在不同心血管风险及肾脏结局的2型糖尿病患者,在原有生活方式干预和/或其他降糖药物的基础上加用钠-葡萄糖共转运蛋白2(SGLT-2)抑制剂和胰高血糖素样肽1(GLP-1)受体激动剂的获益及风险是什么?现行做法几十年来,2型糖尿病的治疗决策都以控制血糖为主导。SGLT-2抑制剂和GLP-1受体激动剂在传统观念中常被用于二甲双胍治疗后血糖仍控制不佳的患者。目前这一现状已经发生了改变,这得益于多项临床研究结果。研究显示SGLT-2抑制剂和GLP-1受体激动剂拥有独立于药物降糖作用之外的对于动脉粥样硬化性心血管病(CVD)和慢性肾脏病(CKD)的获益。建议本指南阐述了针对不同风险分层的成人2型糖尿病患者使用SGLT-2抑制剂或GLP-1受体激动剂的建议。•伴有3种或更少的心血管风险因素且不存在CVD或CKD:不建议启动SGLT-2抑制剂或GLP-1受体激动剂治疗。(推荐等级:弱)•伴有3种以上心血管风险因素且不存在CVD或CKD:建议启动SGLT-2抑制剂治疗,不建议启动GLP-1受体激动剂治疗。(推荐等级:弱)•已经存在CVD或CKD:建议启动SGLT-2抑制剂治疗和GLP-1受体激动剂治疗。(推荐等级:弱)•已经存在CVD和CKD:建议启动SGLT-2抑制剂治疗(推荐等级:强)和GLP-1受体激动剂治疗。(推荐等级:弱)•对于那些想要进一步降低CVD和CKD结局风险的患者:推荐优先启用SGLT-2抑制剂治疗而非GLP-1受体激动剂治疗。(推荐等级:弱)这项指南是如何制订的一个由患者、临床医生和方法学家共同组成的国际小组提出了这些推荐意见。这些推荐意见基于可信度较高的指南的标准,并使用GRADE分级方法进行评估。该小组采用了息者个体化的观点。证据一项关于获益与风险的系统综述和网络meta分析(764项随机对照研究,包括421346例参与者)发现SGLT-2抑制剂和GLP-1受体激动剂可以降低总体死亡率、心肌梗死发生率、终末期肾病或肾衰竭的发生率(中等至高等质量的证据)。在不同的亚组中这些药物对卒中、因心力衰竭所致住院和其他主要不良事件有不同的影响。药物绝对获益的程度因患者个体风险的不同有很大的差异。(例如,对于接受了超过5年药物治疗的1000例患者,在最低风险人群中死亡人数减少了5人,在最高风险人群中死亡人数减少了48人)。一项关于预后的综述确认了14种风险预测模型,其中一种(RECODe)在证据总结中报告了大部分基线风险评估数据,小组利用该模型以支持风险分层的建议。考虑到患者的价值观及个体差异,指南推荐的支撑证据包括一项对已发表论文的系统综述、一项患者焦点小组研究、一项临床问题总结,以及一项指南调查。指南解读我们依据不同的CVD和CKD风险水平,综合考虑获益、风险和其他因素的平衡,以及每一个风险组别的实际问题,来对推荐意见进行分层。本指南强烈建议CVD和CKD患者使用SGLT-2抑制剂治疗,这说明专家组认为其具有显著的获益。而对于其他成人2型糖尿病患者,推荐等级较弱,这说明专家组想要在获益、风险及治疗花费上取得一个更好的平衡。临床医生通过该指南可以使用可靠的风险计算模型,如RECODe,来明确其患者的个体心血管和肾脏疾病风险。医患交互式总结临床证据和制订决策有助于患者知晓治疗选择,包括进行共同决策。2型糖尿病人群(全球患病率不断增长1-2)正面临着不断增加的心血管疾病、肾脏病和其他并发症的风险3。数十年来,2型糖尿病的管理始终以控制血糖及糖化血红蛋白(HbA1c)为治疗目标4-5,但是,最近的高质量随机对照研究已经对这种以血糖为中心的治疗模式发起了挑战。研究结果显示,强化血糖控制未必会降低大血管不良事件,它还可能带来不利影响监管机构现在要求新型糖尿病药物必须证明其具有心血管和肾脏获益才能获得批准。对两类新药--钠-葡萄糖共转运蛋白2(SGLT-2)抑制剂和胰高血糖素样肽1(GLP-1)受体激动剂(见框图1)的临床试验结果显示,在现有治疗方案(常规治疗)之上加用这些药物,对死亡、心肌梗死、卒中、心力衰竭和肾脏的结局(如进展为终末期肾病)都有获益8-12。 | Sheyu Li Per Olav Vandvik Lyubov Lytvyn Gordon H Guyatt Suetonia C Palmer Rene Rodriguez-Gutierrez Farid Foroutan Thomas Agoritsas Reed A C Siemieniuk Michael Walsh Lawrie Frere David J Tunnicliffe Evi V Nagler Veena Manja Bjφrn Olav Asvold Vivekanand Jha Mieke Vermandere Karim Gariani Qian Zhao Yan Ren Emma Jane Cartwright Patrick Gee Alan Wickes Linda Fems Robin Wright Ling Li Qiukui Hao Reem A Mustafa 无 郭鹤鸣(译) | 2021 | 英国医学杂志中文版2021，24，9： | 7 |
| 8 | 稀土氧化物EuO_x对Pt/CeO_2材料在甲苯催化燃烧中的显著促进机制(英文)显示文摘挥发性有机污染物是大气环境中一类重要的污染物质,其污染控制问题已成为21世纪大气污染控制的优先方向之一.甲苯作为一种典型芳香烃在医药、农药、染料合成等多个化工行业中常用作有机化工原料并被排入大气环境,对人类的生产和生活造成极大危害.由于其高致癌性,甲苯在2017年被世界卫生组织国际癌症研究机构列为3类致癌物.在甲苯的催化燃烧降解中,负载型铂基催化剂由于其高效的低温催化活性被学者广泛研究.CeO_2作为一种典型的稀土金属氧化物具有较强的储放氧能力和高温稳定性,被视为负载型贵金属催化剂的优良载体.近期研究表明, EuO_x具有良好的催化氧化活性,并能促进金属氧化物表面氧缺位的形成.为了进一步研究EuO_x与CeO_2之间的协同效应对贵金属基催化剂低温催化性能的影响,我们利用表面模板剂法合成了具有不同Eu负载量的Pt/Eu_2O_3-CeO_2材料并应用于甲苯的深度催化氧化.研究表明, EuO_x的加入显著提高了Pt/CeO_2材料的催化性能,当Eu含量为2.5at%时(Pt/EC-2.5)该材料拥有最佳的低温氧化活性,可在200°C实现对0.09%甲苯的完全降解,在160°C时反应速率和转化频次分别高达0.9 mmolg^(–1)s^(–1)和5.52×10~2s^(–1).相比于Pt/CeO_2催化剂, EuO_x与CeO_2之间的协同作用极大提高了催化剂的氧化还原性能,增大了材料表面晶格氧和Ce3+的含量,并显著提高了贵金属活性相的分散度.通过原位漫反射红外光谱在线分析了甲苯在Pt/Eu_2O_3-CeO_2材料表面的深度降解机理.与甲苯在Pt/CeO_2材料表面的氧化行为相比,甲苯在Pt/EC-2.5催化剂表面的降解遵循典型的Mars-vanKrevelen(MvK)机理.当吸附于稀土金属氧化物载体后,在Pt活性位点、晶格氧及表面酸性位点的联合作用下,甲苯以酮类和醛类为主要的中间产物,被迅速深度氧化为H_2O和CO_2. | 赵宝明 建艳飞 姜泽宇 Reem Albilali 何炽 | 2019 | Chinese Journal of Catalysis2019，40，4： | 7 |
| 9 | New approaches for diagnosis of dry eye disease显示文摘We reviewed the literature for different diagnostic approaches for dry eye disease(DED) including the most recent advances, contradictions and promising diagnostic tools and technique. We performed a broad literature search for articles discussing different methods for diagnosis of DED including assessment of tear osmolarity, tear film stability, ocular biomarkers and others. Articles indexed in PubMed and google scholar were included. With the growing cosmetic industry, environmental pollution, and booming of digital screens, DED is becoming more prevalent. Its multifactorial etiology renders the diagnosis challenging and invites the emergence of new diagnostic tools and tests. Diagnostic tools can be classified, based on the parameter they measure, into tear film osmolarity, functional visual acuity, tear volume, tear turnover, tear film stability, tear film composition, ocular biomarkers and others. Although numerous methods exist, the most accurate diagnosis can be reached through combining the results of more than one test. Many reported tests have shown potential as diagnostic/screening tools, however, require more research to prove their diagnostic power, alone or in combination. Future research should focus on identifying and measuring parameters that are the most specific to DED diagnosis. | Abdelrahman MElhusseiny Ali AKhalil Reem HEl Sheikh Mohammad ABakr MohamedGaber Eissa Yasmine MEl Sayed | 2019 | International Journal of Ophthalmology(English edition)2019，12，10： | 5 |
| 10 | Transcranial magnetic stimulation in animal models of neurodegeneration显示文摘Brain stimulation techniques offer powerful means of modulating the physiology of specific neural structures. In recent years, non-invasive brain stimulation techniques, such as transcranial magnetic stimulation(TMS) and transcranial direct current stimulation, have emerged as therapeutic tools for neurology and neuroscience. However, the possible repercussions of these techniques remain unclear, and there are few reports on the incisive recovery mechanisms through brain stimulation. Although several studies have recommended the use of non-invasive brain stimulation in clinical neuroscience, with a special emphasis on TMS, the suggested mechanisms of action have not been confirmed directly at the neural level. Insights into the neural mechanisms of non-invasive brain stimulation would unveil the strategies necessary to enhance the safety and efficacy of this progressive approach. Therefore, animal studies investigating the mechanisms of TMSinduced recovery at the neural level are crucial for the elaboration of non-invasive brain stimulation. Translational research done using animal models has several advantages and is able to investigate knowledge gaps by directly targeting neuronal levels. In this review, we have discussed the role of TMS in different animal models, the impact of animal studies on various disease states, and the findings regarding brain function of animal models after TMS in pharmacology research. | Mohammad Uzair Turki Abualait Muhammad Arshad Woo-Kyoung Yoo Ali Mir Reem Fahd Bunyan Shahid Bashir | 2022 | Neural Regeneration Research2022，17，2： | 4 |

| 12 | Harnessing digital workflows for the understanding,promotion and participation in the conservation of heritage sites by meeting both ethical and technical challenges显示文摘The current application of digital workflows for the understanding,promotion and participation in the conservation of heritage sites involves several technical challenges and should be governed by serious ethical engagement.Recording consists of capturing(or mapping)the physical characteristics of character-defining elements that provide the significance of cultural heritage sites.Usually,the outcome of this work represents the cornerstone information serving for their conservation,whatever it uses actively for maintaining them or for ensuring a posterity record in case of destruction.The records produced could guide the decision-making process at different levels by property owners,site managers,public officials,and conservators around the world,as well as to present historical knowledge and values of these resources.Rigorous documentation may also serve a broader purpose:over time,it becomes the primary means by which scholars and the public apprehends a site that has since changed radically or disappeared.This contribution is aimed at providing an overview of the potential application and threats of technology utilised by a heritage recording professional by addressing the need to develop ethical principles that can improve the heritage recording practice at large. | Mario Santana Quintero Reem Awad Luigi Barazzetti | 2020 | Built Heritage2020，4，1： | 3 |
| 13 | Play therapy in children with autism:Its role,implications,and limitations显示文摘Play is a pleasurable physical or mental activity that enhances the child’s skills involving negotiation abilities,problem-solving,manual dexterity,sharing,decision-making,and working in a group.Play affects all the brain's areas,structures,and functions.Children with autism have adaptive behavior,adaptive response,and social interaction limitations.This review explores the different applications of play therapy in helping children with autism disorder.Play is usually significantly impaired in children with autism.Play therapy is mainly intended to help children to honor their unique mental abilities and developmental levels.The main aim of play therapy is to prevent or solve psychosocial difficulties and achieve optimal child-healthy growth and development.Play therapy helps children with autism to engage in play activities of their interest and choice to express themselves in the most comfortable ways.It changes their way of self-expression from unwanted behaviors to more non-injurious expressive behavior using toys or activities of their choice as their words.Play therapy also helps those children to experience feeling out various interaction styles.Every child with autism is unique and responds differently.Therefore,different types of intervention,like play therapy,could fit the differences in children with autism.Proper evaluation of the child is mandatory to evaluate which type fits the child more than the others.This narrative review revised the different types of play therapy that could fit children with autism in an evidence-based way.Despite weak evidence,play therapy still has potential benefits for patients and their families. | Reem Elbeltagi Mohammed Al-Beltagi Nermin Kamal Saeed Rawan Alhawamdeh | 2023 | World Journal of Clinical Pediatrics2023，12，1： | 3 |
| 14 | Nutritional assessment in patients with liver cirrhosis显示文摘Malnutrition is a liver cirrhosis complication affecting more than 20%-50%of patients.Although the term can refer to either nutrient deficiency or excess,it usually relates to undernutrition in cirrhosis settings.Frailty is defined as limited physical function due to muscle weakness,whereas sarcopenia is defined as muscle mass loss and an advanced malnutrition stage.The pathogenesis of malnutrition in liver cirrhosis is multifactorial,including decreased oral intake,maldigestion/malabsorption,physical inactivity,hyperammonemia,hypermetabolism,altered macronutrient metabolism and gut microbiome dysbiosis.Patients with chronic liver disease with a Body Mass Index of<18.5 kg/m2 and/or decompensated cirrhosis or Child-Pugh class C are at the highest risk of malnutrition.For patients at risk of malnutrition,a detailed nutritional assessment is required,typically including a history and physical examination,laboratory testing,global assessment tools and body composition testing.The latter can be done using anthropometry,cross-sectional imaging including computed tomography or magnetic resonance,bioelectrical impedance analysis and dual-energy X-ray absorptiometry.A multidisciplinary team should screen for and treat malnutrition in patients with cirrhosis.Malnutrition and sarcopenia are associated with an increased risk of complications and a poor prognosis in patients with liver cirrhosis;thus,it is critical to diagnose these conditions early and initiate the appropriate nutritional therapy.In this review,we describe the prevalence and pathogenesis of malnutrition in liver cirrhosis patients and discuss the best diagnostic approach to nutritional assessment for them. | Sara Haj Ali Awni Abu Sneineh Reem Hasweh | 2022 | World Journal of Hepatology2022，14，9： | 3 |
| 15 | Overcoming scarring in the urethra: Challenges for tissue engineering显示文摘Urethral stricture disease is increasingly common occurring in about 1%of males over the age of 55.The stricture tissue is rich in myofibroblasts and multi-nucleated giant cells which are thought to be related to stricture formation and collagen synthesis.An increase in collagen is associated with the loss of the normal vasculature of the normal urethra.The actual incidence differs based on worldwide populations,geography,and income.The stricture aetiology,location,length and patient’s age and comorbidity are important in deciding the course of treatment.In this review we aim to summarise the existing knowledge of the aetiology of urethral strictures,review current treatment regimens,and present the challenges of using tissue-engineered buccal mucosa(TEBM)to repair scarring of the urethra.In asking this question we are also mindful that recurrent fibrosis occurs in other tissuesdhow can we learn from these other pathologies? | Abdulmuttalip Simsek Reem Aldamanhori Christopher RChapple Sheila MacNeil | 2018 | Asian Journal of Urology2018，5，2： | 3 |
| 16 | Tumor necrosis factor-α-G308A polymorphism is associated with liver pathological changes in hepatitis C virus patients显示文摘AIM To investigate the association of tumor necrosis factor alpha(TNFα)-G308 A polymorphism with different liver pathological changes in treatment-na?ve Egyptian patients infected with hepatitis C virus(HCV) genotype 4.METHODS This study included 180 subjects,composed of 120 treatment-na?ve chronic HCV patients with different fibrosis grades(F0-F4) and 60 healthy controls. The TNFα-G308 A region was amplified by PCR and the different genotypes were detected by restriction fragment length polymorphism analysis. The TNFα protein was detected by enzyme-linked immunosorbent assay. The influence of different TNFα-G308 A genotypes on TNFα expression and liver disease progression were statistically analyzed. The OR and 95%CI were calculated to assess the relative risk confidence.RESULTS Current data showed that the TNFα-G308 A SNP frequency was significantly different between controls and HCV infected patients(P = 0.001). Both the AA genotype and A allele were significantly higher in late fibrosis patients(F2-F4,n = 60) than in early fibrosis patients(F0-F1,n = 60)(P = 0.05,0.04 respectively). Moreover,the GA or AA genotypes increased the TNFα serum level greater than the GG genotype(P = 0.002). The results showed a clear association between severe liver pathological conditions(inflammation,steatosis and fibrosis) and(GA + AA) genotypes(P = 0.035,0.03,0.04 respectively). The stepwise logistic regression analysis showed that the TNFα genotypes(GA + AA) were significantly associated with liver inflammation(OR = 3.776,95%CI: 1.399-10.194,P = 0.009),severe steatosis(OR = 4.49,95%CI: 1.441-14.0,P = 0.010) and fibrosis progression(OR = 2.84,95%CI: 1.080-7.472,P = 0.034). Also,the A allele was an independent risk factor for liver inflammation(P = 0.003),steatosis(P = 0.003) and fibrosis(P = 0.014).

| 17 | Potential role of killer immunoglobulin receptor genes among individuals vaccinated against hepatitis B virus in Lebanon显示文摘AIM To explore the role of killer immunoglobulin receptor(KIR) genes in responsiveness or non-responsiveness to vaccination against hepatitis B virus.METHODS We recruited 101 voluntary participants between March 2010 and December 2011. Sera samples from vaccinated and non-vaccinated participants were tested for the presence of anti-HBs antibodies as a measure of protection against hepatitis B, hepatitis B surface antigen and hepatitis B core antibody as indicators ofinfection by enzyme-linked immunosorbent assay. KIR gene frequencies were determined by polymerase chain reaction.RESULTS Sera samples from 99 participants were tested for the levels of anti-HBs as an indicator of protection(≥ 10 mI U/ml) following vaccination as defined by the World Health Organization international reference standard. Among the vaccinated participants, 47%(35/74) had anti-HBs titers above 100 mI U/ml, 22%(16/74) had antiHBs ranging between 10-100 mI U/ml, and 20%(15/74) had values of less than 10 mI U/ml. We report the lack of significant association between the number of vaccine dosages and the titer of antibodies among our vaccinated participants. The inhibitory KIR2Dl1, KIR2Dl4, KIR3Dl1, KIR3Dl2, and KIR3 Dl were detected in more than 95%, whereas KIR2Dl2, KIR2Dl3, KIR2Dl5(KR2Dl5A and KIR2Dl5B) were expressed in 56%, 84% and 42%(25% and 29%) of participants, respectively. The observed frequency of the activating KIR genes ranged between 35% and 55% except for KIR2DS4, detected in 95% of the study participants(40.6% 2DS4*001/002; 82.2% 2DS4*003/007). KIR2DP1 pseudogene was detected in 99% of our participants, whereas KIR3DP*001/02/04 and KIR3DP1*003 had frequencies of 17% and 100%, respectively. No association between the frequency of KIR genes and anti-HBs antibodies was detected. When we compared the frequency of KIR genes between vaccinated individuals with protective antibodies titers and those who lost their protective antibody levels, we did not detect a significant difference. KIR2Dl5 B was significantly different among different groups of vaccinated participants(group Ⅰ > 100 mI U/ml, group Ⅱ 10-100 mI U/ml, group Ⅲ < 10 mI U/ml and group Ⅳ with undetectable levels of protective antibodies). CONCLUSION To our knowledge, this is the first study screening for the possible role of KIR genes among individuals vaccinated against hepatitis B virus(HBV). Our results can be used to design larger studies to better understand the role of KIR genes in protection against or susceptibility to HBV post vaccination. | Nada M Melhem Rami A Mahfouz Khalil Kreidieh Rabab Abdul-Khalik Rolla El-Khatib Reem Talhouk Umayya Musharrafieh Ghassan Hamadeh | 2016 | World Journal of Hepatology2016，8，29： | 2 |
| 18 | Maternal vitamin D level and vitamin D receptor gene polymorphism as a risk factor for congenital heart diseases in offspring;An Egyptian case-control study显示文摘Vitamin D&vitamin D receptor(VDR)signaling play a very crucial role in early embryonic heart development.We construct this case-control study to investigate the association between maternal serum vitamin D level&VDR gene Fok1 polymorphism and risk of congenital heart defects(CHD)in offspring.Fifty mothers who had term neonates with CHD were considered as cases.Fifty age-comparable healthy mothers who had neonates without CHD were contemplated as controls.Maternal serum 25 hydroxyvitamin D[25(OH)D]level was tested using ELISA.Maternal VDR gene Fok1 polymorphism was analyzed using PCR-based RFLP-assay.There was a significant decrease in maternal vitamin D level(P=0.002)and a significant increase in vitamin D deficient status(P=0.007)among cases when compared to controls.VDR gene Fok1 genotypes distribution frequency were in accordance with Hardy Weinberg equilibrium(HW)among controls.A significant increase in VDR gene Fok1 F/f&f/f genotypes and f allele were observed in cases compared to controls with estimated odds ratio(95%confidence interval)&P-value of 3(1e8)&P=0.006,11(1e97)&P=0.01 and 3(2e6)&P=0.001 respectively.There was a significant decrease in maternal vitamin D level in neonates with cyanotic CHD(P=0.000)compared to those with a cyanotic CHD while there was no significant difference in VDR Fok1 genotype(P=0.18)&allele(P=0.05)distribution between two groups.We concluded that maternal vitamin D deficiency and VDR gene Fok1 F/f,f/f genotype and f allele were associated with increased risk of CHD in offspring. | Wesam A.Mokhtar Amal Fawzy Reem M.Allam Rania M.Amer Mona S.Hamed | 2019 | Genes & Diseases2019，6，2： | 2 |

| 20 | High omega arachidonic acid/docosahexaenoic acid ratio induces mitochondrial dysfunction and altered lipid metabolism in human hepatoma cells显示文摘BACKGROUND Non-alcoholic fatty liver disease(NAFLD) is a common cause of liver disease worldwide and is a growing epidemic. A high ratio of omega-6 fatty acids to omega-3 fatty acids in the diet has been implicated in the development of NAFLD. However, the inflicted cellular pathology remains unknown. A high ratio may promote lipogenic pathways and contribute to reactive oxygen species(ROS)-mediated damage, perhaps leading to mitochondrial dysfunction.Therefore, these parameters were investigated to understand their contribution to NAFLD development.AIM To examine the effect of increasing ratios of omega-6:3 fatty acids on mitochondrial function and lipid metabolism mediators.METHODS Hep G2-derived VL-17 A cells were treated with normal(1:1, 4:1) and high(15:1,25:1) ratios of omega-6: omega-3 fatty acids [arachidonic acid(AA):docosahexaenoic acid(DHA)] at various time points. Mitochondrial activity and function were examined via MTT assay and Seahorse XF24 analyzer, respectively.Triglyceride accumulation was determined by using Enzy Chrom? and levels of ROS were measured by fluorescence intensity. Protein expression of the mediators of lipogenic, lipolytic and endocannabinoid pathways was assessed by Western blotting.RESULTS High AA:DHA ratio decreased mitochondrial activity(P < 0.01;up to 80%) and promoted intracellular triglyceride accumulation(P < 0.05;40%-70%).Mechanistically, it altered the mediators of lipid metabolism;increased the expression of stearoyl-Co A desaturase(P < 0.05;22%-35%), decreased the expression of peroxisome proliferator-activated receptor-alpha(P < 0.05;30%-40%) and increased the expression of cannabinoid receptor 1(P < 0.05;31%).Furthermore, the high ratio increased ROS production(P < 0.01;74%-115%) and reduced mitochondrial respiratory functions such as basal and maximal respiration, ATP production, spare respiratory capacity and proton leak(P < 0.01;35%-68%).CONCLUSION High AA:DHA ratio induced triglyceride accumulation, increased oxidative stress and disrupted mitochondrial functions. Stimulation of lipogenic and steroidal transcription factors may partly mediate these effects and contribute to NAFLD development. | Reem Ghazali Kosha J Mehta SW Annie Bligh Ihab Tewfik Dahn Clemens Vinood B Patel | 2020 | World Journal of Hepatology2020，12，3： | 2 |
