| 1 | Chinese Atherosclerosis Risk Evaluation(CARE II)study:a novel cross-sectional,multicentre study of the prevalence of high-risk atherosclerotic carotid plaque in Chinese patients with ischaemic cerebrovascular events-design and rationale显示文摘Background:Carotid atherosclerotic plaque is identified as one of the main sources of ischaemic stroke.However,the prevalence of carotid high-risk atherosclerotic plaque in Chinese patients with ischaemic cerebrovascular events has been inconsistently reported and needs to be investigated in a large population.Objectives:The primary objective of CARE II study was to determine the prevalence and characteristics of high-risk features of atherosclerotic plaques in the carotid arteries in Chinese patients with recent ischaemic stroke or transient ischaemia attack(TIA).The relationship between carotid plaque features and cerebral infarcts,the differences of carotid plaque patterns among different regions of China and the gender specific characteristics of carotid plaque will be also determined.Study design:The CARE II study will enrol 1000 patients with recent ischaemic stroke or TIA and carotid plaque from 13 hospitals and medical centres across China.In this cross-sectional,non-randomised,observational,multicentre study,all patients will undergo carotid artery MRI of bilateral carotid arteries and routine brain MRI with standardised protocols.The MRI will be interpreted at core reading centres to evaluate the characteristics of morphology and compositions of carotid plaque.Conclusions:This is a cross-sectional,multicentre study to investigate the prevalence and characteristics of high-risk atherosclerotic carotid plaque in Chinese patients with stroke and TIA by using high-resolution MRI of vessel wall.This trial is sufficiently powered to demonstrate the prevalence of carotid high-risk plaque and to explore regional differences in Chinese patients who suffered stroke. | Xihai Zhao Rui Li Daniel S Hippe Thomas S Hatsukami Chun Yuan CARE-II Investigators | 2017 | Stroke & Vascular Neurology2017，2，1： | 21 |
| 2 | Meta-analyses on prevalence of selected Parkinson’s nonmotor symptoms before and after diagnosis显示文摘Background:Nonmotor symptoms are common among patients with Parkinson’s disease(PD)and some may precede disease diagnosis.Methods:We conducted a meta-analysis on the prevalence of selected nonmotor symptoms before and after PD diagnosis,using random-effect models.We searched PubMed(1965 through October/November 2012)for the following symptoms:hyposmia,constipation,rapid eye movement sleep behavior disorder,excessive daytime sleepiness,depression,and anxiety.Eligible studies were publications in English with original data on one or more of these symptoms.Results:The search generated 2,373 non-duplicated publications and 332 met the inclusion criteria,mostly(n=320)on symptoms after PD diagnosis.For all symptoms,the prevalence was substantially higher in PD cases than in controls,each affecting over a third of the patients.Hyposmia was the most prevalent(75.5%in cases vs.19.1%in controls),followed by constipation(50%vs.17.7%),anxiety(39.9%vs.19.1%),rapid eye movement sleep behavior disorder(37.0%vs.7.0%),depression(36.6%vs.14.9%),and excessive daytime sleepiness(33.9%vs.10.5%).We observed substantial heterogeneities across studies and meta-regression analyses suggested that several factors might have contributed to this.However,the prevalence estimates were fairly robust in several sensitivity analyses.Only 20 studies had data on any symptoms prior to PD diagnosis,but still the analyses revealed higher prevalence in future PD cases than in controls.Conclusion:These symptoms are common among PD patients both before and after diagnosis.Further studies are needed to understand the natural history of nonmotor symptoms in PD and their etiological and clinical implications. | Honglei Chen Edward J Zhao Wen Zhang Yi Lu Rui Liu Xuemei Huang Anna J Ciesielski-Jones Michele A Justice Deborah S Cousins Shyamal Peddada | 2015 | Translational Neurodegeneration2015，4，1： | 18 |
| 3 | -765G > C COX-2 polymorphism may be a susceptibility marker for gastric adenocarcinoma in patients with atrophy or intestinal metaplasia显示文摘AIM: To investigate the relationship between the -765G > C COX-2 polymorphism and the development of different gastric lesions: atrophy or intestinal metaplasia and gastric adenocarcinoma. METHODS: A cross-sectional study was performed involving 320 Portuguese individuals (210 without evidence of neoplastic disease, 73 patients with gastric adenocarcinomas and 37 with atrophy or intestinal metaplasia) using a PCR-RFLP method. RESULTS: -765C allele was overrepresented in the patients with gastric adenocarcinoma (51%) when compared either with the control group (38%) or patients with atrophy or intestinal metaplasia (27%). Callele was found to be very common in our population (0.22), and a multivariate logistic regression analysis revealed nearly 3-fold increased risk for the progression to gastric adenocarcinoma in patients with atrophy or intestinal metaplasia carrying the -765C allele (OR = 2.67, 95% CI = 1.03-6.93; P = 0.04).considered as another susceptibility marker for gastric adenocarcinoma development in patients with atrophy or intestinal metaplasia. | Carina Pereira Hugo Sousa Paula Ferreira Maria Fragoso Luís Moreira-Dias Carlos Lopes Rui Medeiros Mário Dinis-Ribeiro | 2006 | World Journal of Gastroenterology2006，12，34： | 16 |
| 4 | The Qitai radio telescope显示文摘This study presents a general outline of the Qitai radio telescope(QTT)project.Qitai,the site of the telescope,is a county of Xinjiang Uygur Autonomous Region of China,located in the east Tianshan Mountains at an elevation of about 1800 m.The QTT is a fully steerable,Gregorian-type telescope with a standard parabolic main reflector of 110 m diameter.The QTT has adopted an umbrella support,homology-symmetric lightweight design.The main reflector is active so that the deformation caused by gravity can be corrected.The structural design aims to ultimately allow high-sensitivity observations from 150 MHz up to115 GHz.To satisfy the requirements for early scientific goals,the QTTwill be equipped with ultra-wideband receivers and large field-of-view multi-beam receivers.A multi-function signal-processing system based on RFSo C and GPU processor chips will be developed.These will enable the QTT to operate in pulsar,spectral line,continuum and Very Long Baseline Interferometer(VLBI)observing modes.Electromagnetic compatibility(EMC)and radio frequency interference(RFI)control techniques are adopted throughout the system design.The QTT will form a world-class observational platform for the detection of lowfrequency(nano Hertz)gravitational waves through pulsar timing array(PTA)techniques,pulsar surveys,the discovery of binary black-hole systems,and exploring dark matter and the origin of life in the universe.The QTT will also play an important role in improving the Chinese and international VLBI networks,allowing high-sensitivity and high-resolution observations of the nuclei of distant galaxies and gravitational lensing systems.Deep astrometric observations will also contribute to improving the accuracy of the celestial reference frame.Potentially,the QTT will be able to support future space activities such as planetary exploration in the solar system and to contribute to the search for extraterrestrial intelligence. | Na Wang Qian Xu Jun Ma Zhiyong Liu Qi Liu Hailong Zhang Xin Pei Maozheng Chen Richard N.Manchester Kejia Lee Xingwu Zheng Hans J.Kärcher Wulin Zhao Hongwei Li Dongwei Li Martin Süss Matthias Reichert Zhongyi Zhu Congsi Wang Mingshuai Li Rui Li Ning Li Guljaina Kazezkhan Wenming Yan Gang Wu Lang Cui Ming Zhang Haitao Li | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，8： | 14 |
| 5 | Solutions for submucosal injection: What to choose and how to do it显示文摘During the past decades, endoscopic resection techniques have gradually improved and gained more importance for the management of premalignant lesions and early cancers. These endoscopic resection techniques can be divided in 3 major groups: snare polipectomy, endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD). The use of submucosal injection is essential for the majority of EMR techniques and is an integral part of ESD,whereas during polipectomy it is not crucial in most cases except to prevent bleeding in large polyps and/or those with large stalks as an alternative to mechanical methods. Injection provides a lifting up effect of the lesion separating it from the muscular layer, thereby reducing thermal injury and the risk of perforation and bleeding while also facilitating en-bloc resection by improving technical feasibility. With this work, we aim to review the most common endoscopic resection techniques and the importance of submucosal injection in each one of them. For that, we present some of the most commonly used submucosal injection solutions, taking into account their advantages and disadvantages. We also discuss, based on current recommendations and our own experience, how and when to preform submucosal injection, depending on lesions features and endoscopic resection technique that′s being used, to assure complete resection and to prevent associated adverse events. Finally, we also present and discuss some new proposed submucosal injection solutions,endoscopic resection techniques and devices that may have a major impact on the future of therapeutic endoscopy. | Rui Castro Diogo Libanio Inês Pita Mário Dinis-Ribeiro | 2019 | World Journal of Gastroenterology2019，25，7： | 13 |
| 6 | Clinical and pathological characterization of epstein-barr virus-associated gastric carcinomas in portugal显示文摘AIM To determine the prevalence of epstein-barr virus(eb V)-associated gastric carcinomas in the North Region of Portugal and to study its clinicopathological characteristics. METHODS We have performed a retrospective study including a total of 179 consecutive patients with gastric cancer(GC) submitted to gastrectomy during 2011 at the Portuguese Oncology Institute of Porto. Clinical and pathological data was collected from individual clinical records and inserted on a database with unique codification. Tumour tissues were collected from the institutional tumour bank. eb V was detected by in situ hybridization for the detection of eb V-encoded small RNAs(ebe Rs) and eb V latent proteins(LMP1 and LMP2 A) were detected by immunohistochemistry.RESULTS The analysis showed that eb V-associated gastric carcinomas(eb Va GC) represents 8.4%(15/179) of all GC cases, with a significant differential distribution among histological types(P < 0.001): 100%(3/3) of medullary carcinomas, 100%(1/1) of adenosquamous carcinoma, 8.7%(8/92) of tubular adenocarcinomas, 8.0%(2/25) of mixed carcinomas and 2%(1/51) in poorly cohesive carcinomas. The analysis revealed a higher predominance of eb Va GC in the upper third and middle(cardia, fundus and body) of the stomach(P = 0.041), a significant lower number of regional lymph nodes invasion(P = 0.025) and a tendency for better prognosis(P = 0.222). eb V latent protein expression revealed that all eb Va GC cases were LMP1-negative, nevertheless 6 cases(40%) expressed LPM2 A, which reveals that these cases show a distinct eb V-Latency profile(latency II-like).CONCLUSION eb Va GC represents 8.4% of all GC in the North Region of Portugal. The eb V-infected patients have specific clinic-pathological features that should be further explored to develop new strategies of management and treatment. | Joana Ribeiro Andreia Oliveira Mariana Malta Claudia Oliveira Fernanda Silva Ana Galaghar Luís Pedro Afonso Maria Cassiano Neves Rui Medeiros Pedro Pimentel-Nunes Hugo Sousa | 2017 | World Journal of Gastroenterology2017，23，40： | 9 |
| 7 | Treatment of malignant digestive tract obstruction by combined intraluminal stent installation and intra-arterial drug infusion显示文摘AIM To study the palliative treatment of malignant obstrution of digestive tract with placement of intraluminal stent combined with intra-arterial infusion of chemotherapeutic drugs.METHODS A total of 281 cases of digestive tract malignant obstruction were given per oral (esophagus,stomach, duodenum and jejunum), per anal (colon and rectum ) and percutaneous transhepatic ( biliary )installation of metallic stent. Among them, 205 cases received drug infusion by cannulation of tumor supplying artery with Seldingers technique.RESULTS Altogether 350 stents were installed in 281 cases, obstructive symptoms were relieved or ameliorated after installation. Occurrence of restenotic obstruction was 8 - 43 weeks among those with intraarterial drug infusion, which was later than 4 - 26 weeks in the group with only stent installation. The average survival time of the former group was 43 (3 - 105) weeks,which was significantly longer than 15 (3- 24) weeks of the latter group.CONCLUSION Intraluminal placement of stent combined with intra-arterial infusion chemotherapy is one of the effective palliative therapies for malignant obstruction of the digestive tract with symptomatic as well as etiological treatment. | Ai-Wu Mao Zhong-Du Gao Jia-Yu Xu Ren-Jie Yang Xiang-Seng Xiao Ting-Hui Jiang Wei-Jun Jiang Department of Interventional Radiology,Shanghai S.T,Luke’s Hospital,768 Yu Yuan Road,Shanghai 200050,ChinaDepartment of Gastroenterology Rui Jin Hospital,Shanghai Second Medical University,Departrnent of Tumor Hospital,Beijing Medical UniversityDepartment of Imaging Chang Zheng Hospital,Shanghai Second Military Medical University | 2001 | World Journal of Gastroenterology2001，7，4： | 6 |

| 9 | Contemporary review of minimally invasive pancreaticoduodenectomy显示文摘AIM To assess the current literature describing various minimally invasive techniques for and to review short-term outcomes after minimally invasive pancreaticoduodenectomy(PD). METHODS PD remains the only potentially curative treatment for periampullary malignancies, including, most commonly, pancreatic adenocarcinoma. Minimally invasive approaches to this complex operation have begun to be increasingly reported in the literature and are purported by some to reduce the historically high morbidity of PD associated with the open technique. In this systematic review, we have searched the literature for high-quality publications describing minimally invasive techniques for PD-including laparoscopic, robotic, and laparoscopicassisted robotic approaches(hybrid approach). We have identified publications with the largest operative experiences from well-known centers of excellence for this complex procedure. We report primarily short term operative and perioperative results and some short term oncologic endpoints. RESULTS Minimal y invasive techniques include laparoscopic, robotic and hybrid approaches and each of these techniques has strong advocates. Consistently, across all minimally invasive modalities, these techniques are associated less intraoperative blood loss than traditional open PD(OPD), but in exchange for longer operating times. These techniques are relatively equivalent in terms of perioperative morbidity and short term oncologic outcomes. Importantly, pancreatic fistula rate appears to be comparable in most minimally invasive series compared to open technique. Impact of minimally invasive technique on length of stay is mixed compared to some traditional open series. A few series have suggestedthat initiation of and time to adjuvant therapy may be improved with minimally invasive techniques, however this assertion remains controversial. In terms of shortterms costs, minimally invasive PD is significantly higher than that of OPD. CONCLUSION Minimally invasive approaches to PD show great promise as a strategy to improve short-term outcomes in patients undergoing PD, but the best results remain isolated to high-volume centers of excellence. | Rui Dai Ryan S Turley Dan G Blazer | 2016 | World Journal of Gastrointestinal Surgery2016，8，12： | 5 |

| 11 | Differences in atheroma between Caucasian and Asian subjects with anterior stroke:A vessel wall MRI study显示文摘Background and purpose While extracranial carotid artery stenosis is more common among Caucasians and intracranial artery stenosis is more common among Asians,the differences in atherosclerotic plaque characteristics have not yet been extensively examined.We sought to investigate plaque location and characteristics within extracranial carotid and intracranial arteries in symptomatic Caucasians and Chinese using vessel wall MRI.Methods Subjects with recent anterior circulation ischaemic stroke were recruited and imaged at two sites in the USA and China using similar protocols.Both extracranial carotid and intracranial arteries were reviewed to determine plaque location and characteristics.Results The prevalence of extracranial carotid plaque in Caucasians and Chinese was 73.1%and 49.1%,respectively(p=0.055).Prevalence of intracranial plaque was 38.5%and 69.1%in Caucasians and Chinese,respectively(p=0.02).Furthermore,42% of Caucasians and 16%of Chinese had high-risk plaque(HRP)features(intraplaque haemorrhage,luminal surface disruption)in the extracranial carotid artery(p=0.03).The prevalence of HRP features in intracranial arteries was not significantly different between the two cohorts(4%vs 11%;p=0.42).Conclusions Differences in the location and characteristics of cerebrovascular atherosclerosis were identified by vessel wall MRI in US Caucasian and Chinese subjects with recent anterior circulation ischaemic stroke.Extracranial carotid plaques with HRP features were more common in Caucasians.Intracranial plaques were more common in Chinese subjects,but no significant difference between the two cohorts in intracranial HRP prevalence was found.Larger studies using vessel wall imaging to investigate racial differences in cerebrovascular disease may inform underlying mechanisms of HRP development and may ultimately help guide appropriate therapy. | Hiroko Watase Mi Shen Binbin Sui Peiyi Gao Dong Zhang Jie Sun Niranjan Balu Daniel S Hippe Gail P Jarvik Xihai Zhao Rui Li Shuo Chen Chun Yuan Thomas S Hatsukami | 2021 | Stroke & Vascular Neurology2021，6，1： | 4 |

Current risk stratification schemes such as the CHADS 2 and CHA 2 DS 2 -VASc scores are based on clinical risk factors and suboptimally weight the risk/benefit of anticoagulation. Recently, the potential of biomarkers (troponin and NT-proBNP) in the RE-LY biomarker sub-analysis has been demonstrated. Echocardiography is also being evaluated as a possible approach to improve risk score performance. The authors present an overview on AF risk stratification and discuss future potential developments that may be introduced into our current risk stratification schemes. | Rui Providência Luís Paiva Sérgio Barra | 2012 | World Journal of Cardiology2012，4，6： | 3 |

| 16 | The heterodimeric structure of heterogeneous nuclear ribonucleoprotein C1/C2 dictates 1,25-dihydroxyvitamin D-directed transcriptional events in osteoblasts显示文摘Heterogeneous nuclear ribonucleoprotein(hnRNP) C plays a key role in RNA processing but also exerts a dominant negative effect on responses to 1,25-dihydroxyvitamin D(1,25(OH)2D) by functioning as a vitamin D response element-binding protein(VDRE-BP). hnRNPC acts a tetramer of hnRNPC1(huC1) and hnRNPC2(huC2), and organization of these subunits is critical to in vivo nucleic acid-binding. Overexpression of either huC1 or huC2 in human osteoblasts is sufficient to confer VDRE-BP suppression of 1,25(OH)2D-mediated transcription. However, huC1 or huC2 alone did not suppress 1,25(OH)2D-induced transcription in mouse osteoblastic cells. By contrast, overexpression of huC1 and huC2 in combination or transfection with a bone-specific polycistronic vector using a ‘‘self-cleaving'' 2A peptide to co-express huC1/C2 suppressed1,25D-mediated induction of osteoblast target gene expression. Structural diversity of hnRNPC between human/NWPs and mouse/rat/rabbit/dog was investigated by analysis of sequence variations within the hnRNP CLZ domain. The predicted loss of distal helical function in hnRNPC from lower species provides an explanation for the altered interaction between huC1/C2 and their mouse counterparts. These data provide new evidence of a role for hnRNPC1/C2 in 1,25(OH)2D-driven gene expression, and further suggest that species-specific tetramerization is a crucial determinant of its actions as a regulator of VDR-directed transactivation. | Thomas S Lisse Kanagasabai Vadivel S Paul Bajaj Rui Zhou Rene F Chun Martin Hewison John S Adams | 2014 | Bone Research2014，2，2： | 2 |

| 18 | Tracheobronchial Polyflex stents for the management of benign refractory hypopharyngeal strictures显示文摘AIM:To describe a modified technique for placement of a tracheobronchial self-expanding plastic stent(SEPS) in patients with benign refractory hypopharyngeal strictures in order to improve dysphagia and allow stricture remodeling.METHODS:A case series of four consecutive patients with complex hypopharyngeal strictures after combinedtherapy for laryngeal cancer,previously submitted to multiple sessions of dilation without lasting improvement,is presented.All patients underwent placement of a small diameter and unflared tracheobronchial SEPS.Main outcome measurements were improvement of dysphagia and avoiding of repeated dilation.RESULTS:The modified introducer system allowed an easy and technically successful deployment of the tracheobronchial Polyflex stent through the stricture.All four patients developed complications related to stent placement.Two patients had stent migration(one proximal and one distal),two patients developed phanryngocutaneous fistulas and all patients with stents in situ for more than 8 wk had hyperplastic tissue growth at the upper end of the stent.Stricture recurrence was observed at 4 wk follow-up after stent removal in all patients CONCLUSION:Although technically feasible,placement of a tracheobronchial SEPS is associated with a high risk of complications.Small diameter stents must be kept in place for longer than 3 mo to allow adequate time for stricture remodeling. | Rui Almeida Silva Nuno Mesquita Pedro Pimentel Nunes Elisabete Cardoso Ricardo Marcos Pinto Luís Moreira Dias | 2012 | World Journal of Gastroenterology2012，18，6： | 2 |

| 20 | Indirect printing of hierarchical patient-specific scaffolds for meniscus tissue engineering显示文摘The complex meniscus tissue plays a critical role in the knee. The high susceptibility to injury has led to an intense pursuit for better tissue engineering regenerative strategies, where scaffolds play a major role. In this study, indirect printed hierarchical multilayered sca ffolds composed by a silk fibroin (SF) upper layer and an 80/20 (w/w) ratio of SF/ionic-doped β-tricalcium phosphate (TCP) bottom layer were developed. Furthermore, a comparative analysis between two types of sca ffolds pro- duced using di fferent SF concentrations, i.e., 8% (w/v) (Hi8) and 16% (w/v) (Hi16) was performed. In terms of architecture and morphology, the produced sca ffolds presented homogeneous porosity in both layers and no di fferences were observed when comparing both sca ffolds. A decrease in terms of mechanical performance of the sca ffolds was observed when SF concentration decreased from 16 to 8% (w/v). Hi16 revealed a static compressive modulus of 0.66 ± 0.05 MPa and dynamical mechanical properties ranging from 2.17 ± 0.25 to 3.19 ± 0.38 MPa. By its turn, Hi8 presented a compressive modulus of 0.27 ± 0.08 MPa and dynamical mechanical properties ranging from 1.03 ± 0.08 MPa to 1.56 ± 0.13 MPa. In vitro bioactivity studies showed formation of apatite crystals onto the surface of Hi8 and Hi16 bottom layers. Human meniscus cells (hMCs) and human primary osteoblasts were cultured separately onto the top layer (SF8 and SF16) and bottom layer (SF8/TCP and SF16/TCP) of the hierarchical sca ffolds Hi8 and Hi16, respectively. Both cell types showed good adhesion and proliferation as denoted by the live/dead staining, Alamar Blue assay and DNA quanti fication analysis. Subcutaneous implantation in mice revealed weak in flammation and sca ffold’s integrity. The hierarchical indirect printed SF sca ffolds can be promising candidate for meniscus TE sca ffolding applications due their suitable mechanical properties, good biological performance and possibility of being applied in a patient-speci fic approach. | Joao BCosta Joana Silva-Correia Sandra Pina Alain da Silva Morais Sílvia Vieira Hélder Pereira Joao Espregueira-Mendes Rui LReis Joaquim M.Oliveira | 2019 | Bio-Design and Manufacturing2019，2，4： | 2 |
