| 1 | Impact of mechanical bowel preparation in elective colorectal surgery:A meta-analysis显示文摘AIM To analyse the effect of mechanical bowel preparation vs no mechanical bowel preparation on outcome in patients undergoing elective colorectal surgery.METHODS Meta-analysis of randomised controlled trials and observational studies comparing adult patients receiving mechanical bowel preparation with those receiving no mechanical bowel preparation, subdivided into those receiving a single rectal enema and those who received no preparation at all prior to elective colorectal surgery. RESULTS A total of 36 studies(23 randomised controlled trials and 13 observational studies) including 21568 patients undergoing elective colorectal surgery were included. When all studies were considered, mechanical bowel preparation was not associated with any significant difference in anastomotic leak rates(OR = 0.90, 95%CI: 0.74 to 1.10, P = 0.32), surgical site infection(OR = 0.99, 95%CI: 0.80 to 1.24, P = 0.96), intraabdominal collection(OR = 0.86, 95%CI: 0.63 to 1.17, P = 0.34), mortality(OR = 0.85, 95%CI: 0.57 to 1.27, P = 0.43), reoperation(OR = 0.91, 95%CI: 0.75 to 1.12, P = 0.38) or hospital length of stay(overall mean difference 0.11 d, 95%CI:-0.51 to 0.73, P = 0.72), when compared with no mechanical bowel preparation, nor when evidence from just randomized controlledtrials was analysed. A sub-analysis of mechanical bowel preparation vs absolutely no preparation or a single rectal enema similarly revealed no differences in clinical outcome measures. CONCLUSION In the most comprehensive meta-analysis of mechanical bowel preparation in elective colorectal surgery to date, this study has suggested that the use of mechanical bowel preparation does not affect the incidence of postoperative complications when compared with no preparation. Hence, mechanical bowel preparation should not be administered routinely prior to elective colorectal surgery. | Katie E Rollins Hannah Javanmard-Emamghissi Dileep N Lobo | 2018 | World Journal of Gastroenterology2018，24，4： | 33 |
| 2 | Epidemiology of age-related macular degeneration (AMD): associations with cardiovascular disease phenotypes and lipid factors显示文摘Age-related macular degeneration(AMD)is the leading cause of irreversible blindness in adults over 50 years old.Genetic,epidemiological,and molecular studies are beginning to unravel the intricate mechanisms underlying this complex disease,which implicate the lipid-cholesterol pathway in the pathophysiology of disease development and progression.Many of the genetic and environmental risk factors associated with AMD are also associated with other complex degenerative diseases of advanced age,including cardiovascular disease(CVD).In this review,we present epidemiological findings associating AMD with a variety of lipid pathway genes,cardiovascular phenotypes,and relevant environmental exposures.Despite a number of studies showing significant associations between AMD and these lipid/cardiovascular factors,results have been mixed and as such the relationships among these factors and AMD remain controversial.It is imperative that researchers not only tease out the various contributions of such factors to AMD development but also the connections between AMD and CVD to develop optimal precision medical care for aging adults. | Katie L.Pennington Margaret M.DeAngelis | 2016 | Eye and Vision2016，3，1： | 22 |

| 4 | From filaments to function: The role of the plant actin cytoskeleton in pathogen perception,signaling and immunity显示文摘The eukaryotic actin cytoskeleton is required for numerous cellular processes, including cell shape, development and movement, gene expression and signal transduction, and response to biotic and abiotic stress. In recent years,research in both plants and animal systems have described a function for actin as the ideal surveillance platform, linking the function and activity of primary physiological processes to the immune system. In this review, we will highlight recent advances that have defined the regulation and breadth of function of the actin cytoskeleton as a network required for defense signaling following pathogen infection. Coupled with an overview of recent work demonstrating specific targeting of the plant actin cytoskeleton by a diversity of pathogens,including bacteria, fungi and viruses, we will highlight the importance of actin as a key signaling hub in plants, one that mediates surveillance of cellular homeostasis and the activation of specific signaling responses following pathogen perception. B4 ased on the studies highlighted herein, we propose a working model that posits changes in actin filament organization is in and of itself a highly specific signal, which induces, regulates and physically directs stimulus-specific signaling processes, most importantly, those associated with response to pathogens. | Katie Porter Brad Day | 2016 | Journal of Integrative Plant Biology2016，58，4： | 12 |
| 5 | Postoperative sleep disorders and their potential impacts on surgical outcomes显示文摘Postoperative sleep disturbance is a common occurrence with significant adverse effects on patients including delayed recovery,impairment of cognitive function,pain sensitivity and cardiovascular events.The development of postoperative sleep disturbance is multifactorial and involves the surgical inflammatory response,the severity of surgical trauma,pain,anxiety,the use of anesthetics and environmental factors such as nocturnal noise and light levels.Many of these factors can be managed perioperatively to minimize the deleterious impact on sleep.Pharmacological and non-pharmacological treatment strategies for postoperative sleep disturbance include dexmedetomidine,zolpidem,melatonin,enhanced recovery after surgery(ERAS) protocol and controlling of environmental noise and light levels.It is likely that a combination of pharmacological and non-pharmacological therapies will have the greatest impact;however,further research is required before their use can be routinely recommended. | Sanketh Rampes Katie Ma Yasmin Amy Divecha Azeem Alam Daqing Ma | 2020 | The Journal of Biomedical Research2020，34，4： | 9 |
| 6 | 在 colorectal 癌症的地岬发信号小径,变化和他们的角色显示文摘 Two of the main cellular pathways in which the RAS protein operates are the mitogen-activated protein kinases (MAPK) and phosphoinositide-3 kinase (PI3K) pathways. In a normal cell, these are important in controlling several functions, such as cell growth and survival. It becomes self-evident that these events will be disrupted in a malignant cell with a deregulated MAPK or PI3K pathway. Mutations in genes involved in these pathways and interacting with RAS, as well as RAS itself will be discussed. The second part of this review concentrates on how crucial RAS signaling is in colorectal cancer progression, with references to treatment response and prognosis when RAS or other related mutations are present. | Kypros Zenonos Katy Kyprianou | 2013 | World Journal of Gastrointestinal Oncology2013，5，5： | 8 |

| 8 | Molecular mechanism and functional consequences of lansoprazole-mediated heme oxygenase-1 induction显示文摘AIM:To investigate the molecular mechanism and functional consequences of heme oxygenase-1(HO-1) activation by lansoprazole in endothelial cells and macrophages. METHODS:Expression of HO-1 mRNA was analyzed by Northern blotting.Western blotting was used to determine the HO-1 and ferritin protein levels. NADPH-dependent reactive oxygen species(ROS) formation was measured with lucigenin-enhanced chemiluminescence.HO-1 promoter activity in mouse fibroblasts,stably transfected with a 15-kb HO-1 gene that drives expression of the reporter gene luciferase, was assessed using in vivo bioluminescence imaging. RESULTS:Lansoprazole increased HO-1 mRNA levels in endothelial cells and HO-1 protein levelsin macrophages.In addition,lansoprazole-induced ferritin protein levels in both cell systems.Moreover, induction of the antioxidant proteins HO-1 and ferritin by lansoprazole was followed by a decrease in NADPH- mediated ROS formation.The radical scavenging properties of lansoprazole were diminished in the presence of the HO inhibitor,chromium mesoporphyrin IX.Induction of HO-1 gene expression by lansoprazole was not related to oxidative stress or to the activation of the mitogen-activated protein kinase pathway. However,the phosphatidylinositol 3-kinase inhibitor LY294002 showed a concentration-dependent inhibition of HO-1 mRNA and promoter activity. CONCLUSION:Activation of HO-1 and ferritin may account for the gastric protection of lansoprazole and is dependent on a pathway blocked by LY294002. | Stephanie Schulz-Geske Kati Erdmann Ronald J Wong David K Stevenson Henning Schrder Nina Grosser | 2009 | World Journal of Gastroenterology2009，15，35： | 7 |
| 9 | Hematopoietic stem cell-derived adipocytes and fibroblasts in the tumor microenvironment显示文摘The tumor microenvironment(TME) is complex and constantly evolving. This is due, in part, to the crosstalk between tumor cells and the multiple cell types that comprise the TME, which results in a heterogeneous population of tumor cells and TME cells. This review will focus on two stromal cell types, the cancerassociated adipocyte(CAA) and the cancer-associated fibroblast(CAF). In the clinic, the presence of CAAs and CAFs in the TME translates to poor prognosis in multiple tumor types. CAAs and CAFs have an activated phenotype and produce growth factors, inflammatory factors, cytokines, chemokines, extracellular matrix components, and proteases in an accelerated and aberrant fashion. Through this activated state, CAAs and CAFs remodel the TME, thereby driving all aspects of tumor progression, including tumor growth and survival, chemoresistance, tumor vascularization, tumor invasion, and tumor cell metastasis. Similarities in the tumorpromoting functions of CAAs and CAFs suggest that a multipronged therapeutic approach may be necessary to achieve maximal impact on disease. While CAAs and CAFs are thought to arise from tissues adjacent to the tumor, multiple alternative origins for CAAs and CAFs have recently been identified. Recent studies from our lab and others suggest that the hematopoietic stem cell, through the myeloid lineage, may serve as a progenitor for CAAs and CAFs. We hypothesize that the multiple origins of CAAs and CAFs may contribute to the heterogeneity seen in the TME. Thus, a better understanding of the origin of CAAs and CAFs, how this origin impacts their functions in the TME, and thetemporal participation of uniquely originating TME cells may lead to novel or improved anti-tumor therapeutics. | Ying Xiong Lindsay T Mc Donald Dayvia L Russell Ryan R Kelly Katie R Wilson Meenal Mehrotra Adam C Soloff Amanda C LaRue | 2015 | World Journal of Stem Cells2015，7，2： | 6 |
| 10 | Application of nanoparticle tracking analysis for characterising the fate of engineered nanoparticles in sediment-water systems显示文摘Novel applications of nanotechnology may lead to the release of engineered nanoparticles(ENPs), which result in concerns over their potential environmental hazardous impact. It is essential for the research workers to be able to quantitatively characterise ENPs in the environment and subsequently to assist the risk assessment of the ENPs. This study hence explored the application of nanoparticle tracking system(NTA) to quantitatively describe the behaviour of the ENPs in natural sediment-water systems. The NTA allows the measurement of both particle number concentration(PNC) and particle size distribution(PSD) of the ENPs. The developed NTA method was applied to a range of gold and magnetite ENPs with a selection of surface properties. The results showed that the positively-charged ENPs interacted more strongly with the sediment than neutral and negatively-charged ENPs. It was also found that the citrate coated Au ENPs had a higher distribution percentage(53%) than 11-mercaptoundecanoic acid coated Au ENPs(20%) and citrate coated magnetite ENPs(21%). The principles of the electrostatic interactions between hard(and soft) acids and bases(HSAB) are used to explain such behaviours; the hard base coating(i.e. citrate ions) will interact more strongly with hard acid(i.e. magnetite) than soft acid(i.e. gold).The results indicate that NTA is a complementary method to existing approaches to characterise the fate and behaviour of ENPs in natural sediment. | Ping Luo Alejandro Roca Karen Tiede Katie Privett Jiachao Jiang John Pinkstone Guibin Ma Jonathan Veinot Alisatair Boxall | 2018 | Journal of Environmental Sciences2018，30，2： | 6 |
| 11 | Influence of vitamin D on liver fibrosis in chronic hepatitis C: A systematic review and meta-analysis of the pooled clinical trials data显示文摘AIM To investigate the relationship between vitamin D and liver fibrosis in hepatitis C-monoinfected or hepatitis C virus(HCV)-human immunodeficiency virus(HIV) coinfected patients. METHODS Pertinent studies were located by a library literature search in PubM ed/Embase/Cochrane/Scopus/LILACS by two individual reviewers. Inclusion criteria:(1) studies with patients with HCV or co-infected HCV/HIV;(2) studies with patients ≥ 18 years old;(3) studies that evaluated liver fibrosis stage, only based on liver biopsy; and(4) studies that reported serum or plasma 25(OH)D levels. Studies that included pediatric patients, other etiologies of liver disease, or did not use liver biopsy for fibrosis evaluation, or studies with inadequate data were excluded. Estimated measures of association reported in the literature, as well as corresponding measures of uncertainty, were recorded and corresponding odds ratios with 95%CI were included in a meta-analysis. RESULTS The pooled data of this systematic review showed that 9 of the 12 studies correlated advanced liver disease defined as a Metavir value of F3/4 with 25(OH) D level insufficiency. The meta-analysis indicated a significant association across studies.CONCLUSION Low vitamin D status is common in chronic Hepatitis C patients and is associated with advanced liver fibrosis. | Alia S Dadabhai Behnam Saberi Katie Lobner Russell T Shinohara Gerard E Mullin | 2017 | World Journal of Hepatology2017，9，5： | 6 |
| 12 | Old vs new: Risk factors predicting early onset colorectal cancer显示文摘BACKGROUND Colorectal cancer(CRC)is the second leading cause of all cancer related deaths in the United States and Europe.Although the incidence has been decreasing for individuals’≥50,it has been on the rise for individuals<50.AIM To identify potential risk factors for early-onset CRC.METHODS A population-based cohort analysis using a national database,Explorys,screened all patients with an active electronic medical record from January 2012 to December 2016 with a diagnosis of CRC.Subgroups were stratified based on age(25–49 years vs≥50 years).Demographics,comorbidities,and symptom profiles were recorded and compared between both age groups.Furthermore,the younger group was also compared with a control group consisting of individuals aged 25-49 years within the same timeframe without a diagnosis of CRC.Twentydata points for CRC related factors were analyzed to identify potential risk factors specific to early-onset CRC.RESULTS A total of 68860 patients were identified with CRC,of which 5710(8.3%)were younger than 50 years old,with 4140(73%)between 40-49 years of age.Multivariable analysis was reported using odds ratio(OR)with 95%CI and demonstrated that several factors were associated with an increased risk of CRC in the early-onset group versus the later-onset group.These factors included:African-American race(OR 1.18,95%CI:1.09-1.27,P<0.001),presenting symptoms of abdominal pain(OR 1.82,95%CI:1.72-1.92,P<0.001),rectal pain(OR 1.50,95%CI:1.28-1.77,P<0.001),altered bowel function(OR 1.12,95%CI:1.05-1.19,P=0.0005),having a family history of any cancer(OR 1.78,95%CI:1.67-1.90,P<0.001),gastrointestinal(GI)malignancy(OR 2.36,95%CI:2.18-2.55,P<0.001),polyps(OR 1.41,95%CI:1.08-1.20,P<0.001),and obesity(OR 1.14,95%CI:1.08-1.20,P<0.001).Comparing the early-onset cohort versus the control group,factors that were associated with an increased risk of CRC were:male gender(OR 1.34,95%CI:1.27-1.41),P<0.001),Caucasian(OR 1.48,95%CI:1.40-1.57,P<0.001)and African-American race(OR 1.25,95%CI:1.17-1.35,P<0.001),presenting symptoms of abdominal pain(OR 4.73,95%CI:4.49-4.98,P<0.001),rectal pain(OR 7.48,95%CI:6.42-8.72,P<0.001),altered bowel function(OR 5.51,95%CI:5.19-5.85,P<0.001),rectal bleeding(OR 9.83,95%CI:9.12-10.6,P<0.001),weight loss(OR 7.43,95%CI:6.77-8.15,P<0.001),having a family history of cancer(OR 11.66,95%CI:10.97-12.39,P<0.001),GI malignancy(OR 28.67,95%CI:26.64-30.86,P<0.001),polyps(OR 8.15,95%CI:6.31-10.52,P<0.001),tobacco use(OR 2.46,95%CI:2.33-2.59,P<0.001),alcohol use(OR 1.71,95%CI:1.62-1.80,P<0.001),presence of colitis(OR 4.10,95%CI:3.79-4.43,P<0.001),and obesity(OR 2.88,95%CI:2.74-3.04,P<0.001).CONCLUSION Pending further investigation,these potential risk factors should lower the threshold of suspicion for early CRC and potentially be used to optimize guidelines for early screening. | Aslam R Syed Payal Thakkar Zachary D Horne Heitham Abdul-Baki Gursimran Kochhar Katie Farah Shyam Thakkar | 2019 | World Journal of Gastrointestinal Oncology2019，11，11： | 6 |
| 13 | Gallbladder cancer:Historical treatment and new management options显示文摘Gallbladder cancer is a rare,aggressive malignancy that has a poor overall prognosis.Effective treatment consists of early detection and surgical treatment.With the wide spread treatment of gallbladder disease with minimally invasive techniques,the rate of incidental gallbladder cancer has seen an equitable rise along with stage migration towards earlier disease.Although the treatment remains mostly surgical,newer modalities such as regional therapy as well as directed therapy based on molecular medicine has led to improved outcomes in patients with advanced disease.We aim to summarize the management of gallbladder cancer along with the newer developments in this formidable disease process. | Kenji Okumura Shekhar Gogna Mahir Gachabayov Daniel Moritz Felsenreich Matthew McGuirk AramRojas Luis Quintero Ramanathan Seshadri Katie Gu Xiang Da Dong | 2021 | World Journal of Gastrointestinal Oncology2021，13，10： | 5 |
| 14 | 污水灌溉对林地土壤中磷的数量与形态影响显示文摘为避免城市生活污水携带的N、P进入水体,新西兰罗托鲁阿市处理后的污水直接喷灌至Whakarewarewa森林,同时建立污水灌溉林地处理系统长期定位试验地,以评价林地生态系统对污水携带营养物质的同化能力。为了解长期污水灌溉对土壤中P的数量、形态、环境的影响,对该灌溉系统中的土壤进行了剖面采样分析。结果表明:土壤TP(全磷)、Olsen P、M3P(Mehlich-3 P)在所有灌溉区的表层土壤(0~10 cm)均有显著(p<0.05)增加,部分指标的显著增加达深层土壤。随灌溉进入土壤的P大多被保存在上层土壤(0~40 cm)中。土壤中各形态的磷所占比例因长期污水灌溉而改变,灌溉前占优势的NaOH Po(以NaOH浸提得到的有机磷)经长期灌溉后被NaOH Pi(以NaOH浸提得到的无机磷)所取代,上层土壤WSP(水溶性磷,Wa-ter-soluble P)变化明显。以Olsen P 60 mg kg-1和M3P 150 mg kg-1为环境临界值可预测土壤剖面中P的淋失危机,WSP可望成为适用更广的土壤P淋失环境危机预测指标。 | 胡慧蓉 王海龙 Katie Beecroft Mark Kimberley | 2012 | 土壤学报2012，49，3： | 5 |

| 16 | 南极Lambert,Mellor和Fisher冰川的物质平衡及Amery冰架底部物质通量的估算显示文摘利用现场观测与遥感数据对Lambert,Mellor和Fisher冰川的物质平衡及其在Amery冰架的底部融化与冻结状况进行了估算.结果表明,澳大利亚组织的Lambert冰川盆地(LGB)考察路线的上游地区,Lambert与Mellor冰川分别为(3.9±2.1)和(2.1±2.4)Gt·a-1的正平衡,而Fisher冰川基本处于平衡状态.上游地区总的正平衡为(5.9±4.9)Gt·a-1.考察路线以下,3条冰川均处于负平衡,总的负平衡为(-8.5±5.8)Gt·a-1.整个Lambert,Mellor和Fisher冰川均接近于平衡状态.3条冰川总净平衡为(-2.6±6.5)Gt·a-1.前人认为GL线(1970年代初澳大利亚在LGB建立的冰川运动观测点的连线)以上的内陆盆地处于显著正平衡,可能是因为过高地估算了总积累量,并低估了穿过GL线的冰通量.靠近Amery冰架南端着地线,冰架底部的平均融化速率为(-23.0±3.5)m冰·a-1,向下游方向快速减小,并在距冰架最南端约300km处过渡为底部冻结.沿3条冰川在Amery冰架的冰流带(flowband),冻结速率约介于(0.5±0.1)^(1.5±0.2)m冰·a-1.由于冰流带底部的融化,流入冰架的内陆冰损失了大约80%±5%.3条冰流带底部总融化和总冻结分别为(50.3±7.5)和(7.0±1.1)Gt冰·a-1,这要比前人通过模拟和海洋观测估算的整个Amery冰架底部总融化和总冻结还要大很多. | 温家洪 Kenneth C.Jezek Beata M.Csathó Ute C.Herzfeld Katy L.Farness Philippe Huybrechts | 2007 | 中国科学(D辑)2007，37，9： | 4 |
| 17 | Evolution of stereoscopic imaging in surgery and recent advances显示文摘In the late 1980s the first laparoscopic cholecystectomies were performed prompting a sudden rise in technological innovations as the benefits and feasibility of minimal access surgery became recognised.Monocular laparoscopes provided only two-dimensional(2D) viewing with reduced depth perception and contributed to an extended learning curve.Attention turned to producing a usable three-dimensional(3D) endoscopic view for surgeons;utilising different technologies for image capture and image projection.These evolving visual systems have been assessed in various research environments with conflicting outcomes of success and usability,and no overall consensus to their benefit.This review article aims to provide an explanation of the different types of technologies,summarise the published literature evaluating 3D vs 2D laparoscopy,to explain the conflicting outcomes,and discuss the current consensus view. | Katie Schwab Ralph Smith Vanessa Brown Martin Whyte Iain Jourdan | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，8： | 4 |
| 18 | Synthesis and transformation of zero-dimensional Cs3BiX6(X=Cl,Br)perovskite-analogue nanocrystals显示文摘The unique structure of zero-dimensional(0D)perovskite-analogues has attracted a great amount of research interest in recent years.To date,the current compositional library of 0D perovskites is largely limited to the lead-based Cs4PbX6(X=Cl,Br,and I)systems.In this work,we report a new synthesis of lead-free 0D Cs3BiX6(X=Cl,Br)perovskite-analogue nanocrystals(NCs)with a uniform cubic shape.We observe a broad photoluminescence peak centered at 390 nm for the 0D Cs3BiCl6 NCs at low temperatures.This feature originates from a self-trapped exciton mechanism.In situ thermal stability studies show that Cs3BiX6 NCs remain stable upon heating up to 200°C without crystal structural degradation.Moreover,we demonstrate that the Cs3BiX6 NCs can transform into other bismuth-based perovskite-analogues via facile anion exchange or metal ion insertion reactions.Our study presented here offers the opportunity for further understanding of the structure-property relationship of 0D perovskite-analogue materials,leading toward their future optoelectronic applications. | Hanjun Yang Tong Cai Exian Liu Katie Hills-Kimball Jianbo Gao Ou Chen | 2020 | Nano Research2020，13，1： | 4 |
| 19 | Adrenal G protein-coupled receptor kinase-2 in regulation of sympathetic nervous system activity in heart failure显示文摘Heart failure(HF), the number one cause of death in the western world, is caused by the insufficient performance of the heart leading to tissue underperfusion in response to an injury or insult. It comprises complex interactions between important neurohormonal mechanisms that try but ultimately fail to sustain cardiac output. The most prominent such mechanism is the sympathetic(adrenergic) nervous system(SNS), whose activity and outflow are greatly elevated in HF. SNS hyperactivity confers significant toxicity to the failing heart and markedly increases HF morbidity and mortality via excessive activation of adrenergic receptors, which are G protein-coupled receptors. Thus, ligand binding induces their coupling to heterotrimeric G proteins that transduce intracellular signals. G protein signaling is turned-off by the agonist-bound receptor phosphorylation courtesy of G protein-coupled receptor kinases(GRKs), followed by βarrestin binding, which prevents the GRK-phosphorylated receptor from further interaction with the G proteins and simultaneously leads it inside the cell(receptor sequestration). Recent evidence indicates that adrenal GRK2 and βarrestins can regulate adrenal catecholamine secretion, thereby modulating SNS activity in HF. The present review gives an account of all these studies on adrenal GRKs and βarrestins in HF and discusses the exciting new therapeutic possibilities for chronic HF offered by targeting these proteins pharmacologically. | Katie A Mc Crink Ava Brill Anastasios Lymperopoulos | 2015 | World Journal of Cardiology2015，7，9： | 4 |
