| 1 | Analysis of the phosphatidylinosit ol 3'-kinase signaling pathway in glioblastoma patients in vivo显示文摘Deregulated signaling through the p hosphatidylinositol 3-kinase(PI3K)pathway is common in many types of can cer,including glioblastoma.Dissecting the molecular events associated with activation of this pathway in glioblastoma p atients in vivo presents an important challenge that has implic ations for the development and clini cal testing of PI3K pathway inhibito rs.Using an immunohistochemical analysis appl ied to a tissue microarray,we performed hierarchical clustering and mul tidimensional scaling,as well as univariate and multivariate analyses,to dissect the PI3K pathway in v ivo.We demonstrate that loss of the t umor suppressor protein PTEN,which antagonizes PI3K pathwa y activation,is highly correlated w ith activation of the main PI3K effec tor Akt in vivo.We also show that Akt activation is signific antly correlated with phosphorylation of mammalian target of rapamycin(mTOR),the family of forkhead transcription factors(FOXO1,FOXO3a,and FOXO4),and S6,which are thought to promote its effects.Expression of the mutan t epidermal growth factor receptor vIII is also tightly correlated with phosphorylation of these effectors,d emonstrating an additional route to PI3K pathway activation in glioblastomas in vivo.These results provide the first dissection of the PI3K path way in glioblastoma in vivo and suggest an approach to stratifying patients for targeted kinase inhi bitor | Choe G Horvath S Cloughesy TF Crosby K Seligson D Palotie A Inge L Smith BL Sawyers CL Mischel PS | 2003 | 癌症2003，22，7： | 41 |

| 3 | Role of the gut microbiota in inflammatory bowel disease pathogenesis: What have we learnt in the past 10 years?显示文摘Our understanding of the microbial involvement in inflammatory bowel disease(IBD) pathogenesis has increased exponentially over the past decade. The development of newer molecular tools for the global assessment of the gut microbiome and the identification of nucleotide-binding oligomerization domain-containing protein 2 in 2001 and other susceptibility genes for Crohn's disease in particular has led to better understanding of the aetiopathogenesis of IBD. The microbial studies have elaborated the normal composition of the gut microbiome and its perturbations in the setting of IBD. This altered microbiome or 'dysbiosis' is a key player in the protracted course of inflammation in IBD. Numerous genome-wide association studies have identified further genes involved in gastrointestinal innate immunity(including polymorphisms in genes involved in autophagy: ATG16L1 and IGRM), which have helped elucidate the relationship of the local innate immunity with the adjacent luminal bacteria. These developments have also spurred the search for specific pathogens which may have a role in the metamorphosis of the gut microbiome from a symbiotic entity to a putative pathogenic one. Here we review advances in our understanding of microbial involvement in IBD pathogenesis over the past 10 years and offer insight into how this will shape our therapeutic management of the disease in the coming years. | Georgina L Hold Megan Smith Charlie Grange Euan Robert Watt Emad M El-Omar Indrani Mukhopadhya | 2014 | World Journal of Gastroenterology2014，20，5： | 21 |

| 6 | 1990—2017年中国伤害负担:2017年全球疾病负担研究结果(摘译)显示文摘伤害是全球性的公共卫生挑战,涉及各年龄组和不同性别的人群。过去三十年来,中国经济快速发展,人口老龄化趋势加重,社会呈现出城镇化、机动化和老龄化等特征。随着人们生活环境和生活方式的改变,伤害已跃居人群致死原因第五位,仅排在恶性肿瘤、心脑血管疾病、呼吸系统疾病和心肌梗死之后。据估计,中国每年在伤害方面消耗的直接医疗费用约为650亿元人民币. | 林泽婷(译) 吕来文(译) 黄晓晴(译) 李丽萍(审校) Duan Leilei Ye Pengpeng Juanita A Haagsma Jin Ye Wang Yuan Er Yuliang Deng Xiao Gao Xin Ji Cuirong Wang Linhong Marlena S Bannick W Cli Mountjoy-Venning Caitlin N Hawley Zichen Liu Mari Smith Spencer L James Theo Vos Christopher J L Murray | 2020 | 伤害医学(电子版)2020，9，2： | 15 |
| 7 | Encapsulating peritoneal sclerosis显示文摘Encapsulating peritoneal sclerosis(EPS) is a debilitating condition characterized by a fibrocollagenous membrane encasing the small intestine, resulting in recurrent small bowel obstructions. EPS is most commonly associated with long-term peritoneal dialysis, though medications, peritoneal infection, and systemic inflammatory disorders have been implicated. Many cases remain idiopathic. Diagnosis is often delayed given the rarity of the disorder combined with non-specific symptoms and laboratory findings. Although cross-sectional imaging with computed tomography of the abdomen can be suggestive of the disorder, many patients undergo exploratory laparotomy for diagnosis. Mortality approaches 50% one year after diagnosis. Treatment for EPS involves treating the underlying condition or eliminating possible inciting agents(i.e. peritoneal dialysis, medications, infections) and nutritional support, frequently with total parenteral nutrition. EPSspecific treatment depends on the disease stage. In the inflammatory stage, corticosteroids are the treatment of choice, while in the fibrotic stage, tamoxifen may be beneficial. In practice, distinguishing between stages may be difficult and both may be used. Surgical intervention, consisting of peritonectomy and enterolysis, is timeconsuming and high-risk and is reserved for situations in which conservative medical therapy fails in institutions with surgical expertise in this area. Herein we review the available literature of the etiology, pathogenesis, diagnosis, and treatment of this rare, but potentially devastating disease. | Christopher J Danford Steven C Lin Martin P Smith Jacqueline L Wolf | 2018 | World Journal of Gastroenterology2018，24，28： | 13 |

| 11 | 缺血性脑卒中患者血压与住院临床结局的相关性显示文摘高血压是脑卒中的主要危险因素。研究表明,在缺血性脑卒中患者中,由于压力依赖性的脑血液流向缺血区域,脑卒中后高血压有益。然而,其他研究显示,脑卒中后的高血压与短期再发性脑卒中、脑出血性转化和脑水肿发生率升高有关。关于血压与脑卒中短期临床结局相关性的观察性研究结论相互矛盾。此外,关于血压的搏动组分(脉压)或稳定组分(平均动脉压)与临床结局相关性的数据有限。 | Bangalore S Schwamm L Smith EE Hellkamp AS Suter RE Xian Y Schulte PJ Fonarow GC Bhatt DL 练桂丽 叶鹏 | 2017 | 中华高血压杂志2017，25，11： | 5 |
| 12 | Mediastinal node staging by positron emission tomographycomputed tomography and selective endoscopic ultrasound with fine needle aspiration for patients with upper gastrointestinal cancer:Results from a regional centre显示文摘AIM To investigate the impact of endoscopic ultrasound-guided fine-needle aspiration(EUS-FNA) and positron emission tomography-computed tomography(PET-CT) in the nodal staging of upper gastrointestinal(GI) cancer in a tertiary referral centre.METHODS We performed a retrospective review of prospectively recorded data held on all patients with a diagnosis of upper GI cancer made between January 2009 and December 2015. Only those patients who had both a PET-CT and EUS with FNA sampling of a mediastinal node distant from the primary tumour were included. Using a positive EUS-FNA result as the gold standard for lymph node involvement, the sensitivity, specificity, positive and negative predictive values(PPV and NPV) and accuracy of PET-CT in the staging of mediastinal lymph nodes were calculated. The impact on therapeutic strategy of adding EUS-FNA to PET-CT was assessed.RESULTS One hundred and twenty one patients were included. Sixty nine patients had a diagnosis of oesophageal adenocarcinoma(Thirty one of whom were junctional), forty eight had oesophageal squamous cell carcinoma and four had gastric adenocarcinoma. The FNA results were inadequate in eleven cases and the PET-CT findings were indeterminate in two cases, therefore thirteen patients(10.7%) were excluded from further analysis. There was concordance between PET-CT and EUS-FNA findings in seventy one of the remaining one hundred and eight patients(65.7%). The sensitivity, specificity, PPV and NPV values of PET-CT were 92.5%, 50%, 52.1% and 91.9% respectively. There was discordance between PET-CT and EUS-FNA findings in thirty seven out of one hundred and eight patients(34.3%). MDT discussion led to a radical treatment pathway in twenty seven of these cases, after the final tumour stage was altered as a direct consequence of the EUS-FNA findings. Of these patients, fourteen(51.9%) experienced clinical remission of a median of nine months(range three to forty two months). CONCLUSION EUS-FNA leads to altered staging of upper GI cancer, resulting in more patients receiving radical treatment that would have been the case using PET-CT staging alone. | Chris Harrington Lyn Smith Jennifer Bisland Elisabet López González Neil Jamieson Stuart Paterson Adrian John Stanley | 2018 | World Journal of Gastrointestinal Endoscopy2018，10，1： | 4 |
| 13 | Outcomes of Medicare beneficiaries hospitalised with transient ischaemic attack and stratification using the ABCD^(2) score显示文摘Background Long-term outcomes for Medicare beneficiaries hospitalised with transient ischaemic attack(TIA)and role of ABCD^(2) score in identifying high-risk individuals are not studied.Methods We identified 40825 Medicare beneficiaries hospitalised from 2011 to 2014 for a TIA to a Get With The Guidelines(GWTG)-Stroke hospital and classified them using ABCD^(2)s of mortality and rehospitalisation(all-cause,ischaemic stroke,haemorrhagic stroke,myocardial infarction,and gastrointestinal and intracranial haemorrhage)for high-risk versus low-risk groups adjusted for patient and hospital characteristics.Results Of the 40825 patients,35118(86%)were high risk(ABCD^(2)≥4)and 5707(14%)were low risk(ABCD^(2)=0-3).Overall rate of mortality during 1-year follow-up after hospital discharge for the index TIA was 11.7%,44.3% were rehospitalised for any reason and 3.6%were readmitted due to stroke.Patients with ABCD^(2) score≥4 had higher mortality at 1 year than not(adjusted HR 1.18,95%CI 1.07 to 1.30).Adjusted risks for ischaemic stroke,all-cause readmission and mortality/all-cause readmission at 1 year were also significantly higher for patients with ABCD^(2) score≥4 vs 0-3.In contrast,haemorrhagic stroke,myocardial infarction,gastrointestinal bleeding and intracranial haemorrhage risk were not significantly different by ABCD^(2) score.Conclusions This study validates the use of ABCD^(2) score for long-term risk assessment after TIA in patients aged 65 years and older.Attentive efforts for community-based follow-up care after TIA are needed for ongoing prevention in Medicare beneficiaries who were hospitalised for TIA. | Shreyansh Shah Li Liang Durgesh Bhandary Saga Johansson Eric E Smith Deepak L Bhatt Gregg C Fonarow Naeem D Khan Eric Peterson Janet Prvu Bettger | 2021 | Stroke & Vascular Neurology2021，6，2： | 3 |
| 14 | Muscle force and movement variability before and after total knee arthroplasty: A review显示文摘Variability in muscle force output and movement variability are important aspects of identifying individuals with mobility deficits, central nervous system impairments, and future risk of falling. This has been investigated in elderly healthy and impaired adults, as well as in adults with osteoarthritis(OA), but the question of whether the same correlations also apply to those who have undergone a surgical intervention such as total knee arthroplasty(TKA) is still being investigated. While there is a growing body of literature identifying potential rehabilitation targets for individuals who have undergone TKA, it is important to first understand the underlying post-operative impairments to more efficiently target functional deficits that may lead to improvedlong-term outcomes. The purpose of this article is to review the potential role of muscle force output and movement variability in TKA recipients. The narrative review relies on existing literature in elderly healthy and impaired individuals, as well as in those with OA before and following TKA. The variables that may predict longterm functional abilities and deficits are discussed in the context of existing literature in healthy older adults and older adults with OA and following TKA, as well as the role future research in this field may play in providing evidence-based data for improved rehabilitation targets. | Jessica W Smith Jesse C Christensen Robin L Marcus Paul C LaStayo | 2014 | World Journal of Orthopedics2014，5，2： | 3 |
