| 1 | Phase 1 human trial of autologous bone marrow-hematopoietic stem cell transplantation in patients with decompensated cirrhosis显示文摘AIM: To evaluate safety and feasibility of autologous bone marrow-enriched CD34+ hematopoietic stem cell Tx through the hepatic artery in patients with decompensated cirrhosis.METHODS: Four patients with decompensated cirrhosis were included. Approximately 200 mL of the bone marrow of the patients was aspirated, and CD34+ stem cells were selected. Between 3 to 10 million CD34+ cells were isolated. The cells were slowly infused through the hepatic artery of the patients.RESULTS: Patient 1 showed marginal improvement in serum albumin and no significant changes in other test results. In patient 2 prothrombin time was decreased; however, her total bilirubin, serum creatinine, and Model of End-Stage Liver Disease (MELD) score worsened at the end of follow up. In patient 3 there was improvement in serum albumin, porthrombin time (PT), and MELD score. Patient 4 developed radiocontrast nephropathy after the procedure, and progressed to type 1 hepatorenal syndrome and died of liver failure a few days later. Because of the major side effects seen in the last patient, the trial was prematurely stopped.CONCLUSION: Infusion of CD34+ stem cells through the hepatic artery is not safe in decompensated cirrhosis. Radiocontrast nephropathy and hepatorenal syndrome could be major side effects. However, this study doesnot preclude infusion of CD34+ stem cells through other routes. | Mehdi Mohamadnejad Mehrnaz Namiri Mohamad Bagheri Seyed Masiha Hashemi Hossein Ghanaati Narges Zare Mehrjardi Saeed Kazemi Ashtiani Reza Malekzadeh Hossein Baharvand | 2007 | World Journal of Gastroenterology2007，13，24： | 74 |
| 2 | Spontaneous bacterial peritonitis显示文摘Since its initial description in 1964,research hastransformed spontaneous bacterial peritonitis (SBP)from a feared disease (with reported mortality of 90%)to a treatable complication of decompensated cirrhosis,albeit with steady prevalence and a high recurrencerate. Bacterial translocation,the key mechanism in thepathogenesis of SBP,is only possible because of theconcurrent failure of defensive mechanisms in cirrhosis.Variants of SBP should be treated. Leucocyte esterasereagent strips have managed to shorten the 'tap-to-shot' time,while future studies should look into theircombined use with ascitic fluid pH. Third generationcephalosporins are the antibiotic of choice becausethey have a number of advantages. Renal dysfunctionhas been shown to be an independent predictor ofmortality in patients with SBP. Albumin is felt to reducethe risk of renal impairment by improving effectiveintravascular volume,and by helping to bind pro-inflammatory molecules. Following a single episodeof SBP,patients should have long-term antibioticprophylaxis and be considered for liver transplantation. | Anastasios Koulaouzidis Shivaram Bhat Athar A Saeed | 2009 | World Journal of Gastroenterology2009，15，9： | 31 |

| 4 | Warpage and Shrinkage Optimization of Injection-Molded Plastic Spoon Parts for Biodegradable Polymers Using Taguchi, ANOVA and Artificial Neural Network Methods显示文摘In this study, it is attempted to give an insight into the injection processability of three self-prepared polymers from A to Z. This work presents material analysis, injection molding simulation, design of experiments alongside considering all interaction effects of controlling parameters carefully for green biodegradable polymeric systems, including polylactic acid(PLA), polylactic acid-thermoplastic polyurethane(PLA-TPU) and polylactic acid-thermoplastic starch(PLA-TPS). The experiments were carried out using injection molding simulation software Autodesk Moldflow?in order to minimize warpage and volumetric shrinkage for each of the mentioned systems. The analysis was conducted by changing five significant processing parameters, including coolant temperature, packing time, packing pressure, mold temperature and melt temperature. Taguchi's L27(35) orthogonal array was selected as an efficient method for design of simulations in order to consider the interaction effects of the parameters and reduce spurious simulations. Meanwhile, artificial neural network(ANN) was also used for pattern recognition and optimization through modifying the processing conditions. The Taguchi coupled analysis of variance(ANOVA) and ANN analysis resulted in definition of optimum levels for each factor by two completely different methods. According to the results, melting temperature, coolant temperature and packing time had significant influence on the shrinkage and warpage. The ANN optimal level selection for minimization of shrinkage and/or warpage is in good agreement with ANOVA optimal level selection results. This investigation indicates that PLA-TPU compound exhibits the highest resistance to warpage and shrinkage defects compared to the other studied compounds. | Erfan Oliaei Behzad Shiroud Heidari Seyed Mohammad Davachi Mozhgan Bahrami Saeed Davoodi Iman Hejazi Javad Seyfi | 2016 | Journal of Materials Science & Technology2016，32，8： | 26 |

| 10 | Optimal PD/PID control of smart base isolated buildings equipped with piezoelectric friction dampers显示文摘Long-period pulses in near-field earthquakes lead to large displacements in the base of isolated structures.To dissipate energy in isolated structures using semi-active control,piezoelectric friction dampers(PFD) can be employed.The performance of a PFD is highly dependent on the strategy applied to adjust its contact force.In this paper,the seismic control of a benchmark isolated building equipped with PFD using PD/PID controllers is developed.Using genetic algorithms,these controllers are optimized to create a balance between the performance and robustness of the closed-loop structural system.One advantage of this technique is that the controller forces can easily be estimated.In addition,the structure is equipped with only a single sensor at the base floor to measure the base displacement.Considering seven pairs of earthquakes and nine performance indices,the performance of the closed-loop system is evaluated.Then,the results are compared with those given by two well-known methods:the maximum possive operation of piezoelectric friction dampers and LQG controllers.The simulation results show that the proposed controllers perform better than the others in terms of simultaneous reduction of floor acceleration and maximum displacement of the isolator.Moreover,they are able to reduce the displacement of the isolator systems for different earthquakes without losing the advantages of isolation. | Sadegh Etedali Mohammad Reza Sohrabi Saeed Tavakoli | 2013 | Earthquake Engineering and Engineering Vibration2013，12，1： | 17 |
| 11 | 第 7 肺癌症 TNM 分类和阶段系统: 变化和含意的评论显示文摘 Lung cancer is the most common cause of death from cancer in males,accounting for more than 1.4 million deaths in 2008.It is a growing concern in China,Asia and Africa as well.Accurate staging of the disease is an important part of the management as it provides estimation of patient’s prognosis and identifies treatment sterategies.It also helps to build a database for future staging projects.A major revision of lung cancer staging has been announced with effect from January 2010.The new classification is based on a larger surgical and non-surgical cohort of patients,and thus more accurate in terms of outcome prediction compared to the previous classification.There are several original papers regarding this new classification which give comprehensive description of the methodology,the changes in the staging and the statistical analysis.This overview is a simplified description of the changes in the new classification and their potential impact on patients’ treatment and prognosis. | Saeed Mirsadraee Dilip Oswal Yalda Alizadeh Andrea Caulo Edwin JR van Beek | 2012 | World Journal of Radiology2012，4，4： | 15 |
| 12 | Antibiotic resistance and cagA gene correlation:A looming crisis of Helicobacter pylori显示文摘AIM:To determine antibiotic resistance of Helicobacter pylori(H.pylori) in Pakistan and its correlation with host and pathogen associated factors.METHODS:A total of 178 strains of H.pylori were isolated from gastric biopsies of dyspeptic patients.Susceptibility patterns against first and second-line antibiotics were determined and trends of resistance were analyzed in relation to the sampling period,gastric conditions and cagA gene carriage.The effect of cagA gene on the acquisition of resistance was investigated by mutant selection assay.RESULTS:The observations showed that monoresistant strains were prevalent with rates of 89% for metronidazole,36% for clarithromycin,37% for amoxicillin,18.5% for ofloxacin and 12% for tetracycline.Furthermore,clarithromycin resistance was on the rise from 2005 to 2008(32% vs 38%,P = 0.004) and it is significantly observed in non ulcerative dyspeptic patients compared to gastritis,gastric ulcer and duodenal ulcer cases(53% vs 20%,18% and 19%,P = 0.000).On the contrary,metronidazole and ofloxacin resistance were more common in gastritis and gastric ulcer cases.Distribution analysis and frequencies of resistant mutants in vitro correlated with the absence of cagA gene with metronidazole and ofloxacin resistance.CONCLUSION:The study confirms the alarming levels of antibiotic resistance associated with the degree of gastric inflammation and cagA gene carriage in H.pylori strains. | Adnan Khan Amber Farooqui Hamid Manzoor Syed Shakeel Akhtar Muhammad Saeed Quraishy Shahana Urooj Kazmi | 2012 | World Journal of Gastroenterology2012，18，18： | 15 |
| 13 | Smart scaffolds in bone tissue engineering: A systematic review of literature显示文摘AIM: To improve osteogenic differentiation and attachment of cells.METHODS: An electronic search was conducted inPub Med from January 2004 to December 2013. Studies which performed smart modifications on conventional bone scaffold materials were included. Scaffolds with controlled release or encapsulation of bioactive molecules were not included. Experiments which did not investigate response of cells toward the scaffold(cell attachment, proliferation or osteoblastic differentiation) were excluded. RESULTS: Among 1458 studies, 38 met the inclusion and exclusion criteria. The main scaffold varied extensively among the included studies. Smart modifications included addition of growth factors(group Ⅰ-11 studies), extracellular matrix-like molecules(group Ⅱ-13 studies) and nanoparticles(nano-HA)(group Ⅲ-17 studies). In all groups, surface coating was the most commonly applied approach for smart modification of scaffolds. In group I, bone morphogenetic proteins were mainly used as growth factor stabilized on polycaprolactone(PCL). In group Ⅱ, collagen 1 in combination with PCL, hydroxyapatite(HA) and tricalcium phosphate were the most frequent scaffolds used. In the third group, nano-HA with PCL and chitosan were used the most. As variable methods were used, a thorough and comprehensible compare between the results and approaches was unattainable.CONCLUSION: Regarding the variability in methodology of these in vitro studies it was demonstrated that smart modification of scaffolds can improve tissue properties. | Saeed Reza Motamedian Sepanta Hosseinpour Mitra Ghazizadeh Ahsaie Arash Khojasteh | 2015 | World Journal of Stem Cells2015，7，3： | 15 |
| 14 | Autonomous vehicles: challenges, opportunities, and future implications for transportation policies显示文摘This study investigates the challenges and opportunities pertaining to transportation policies that may arise as a result of emerging autonomous vehicle(AV)technologies. AV technologies can decrease the transportation cost and increase accessibility to low-income households and persons with mobility issues. This emerging technology also has far-reaching applications and implications beyond all current expectations. This paper provides a comprehensive review of the relevant literature and explores a broad spectrum of issues from safety to machine ethics. An indispensable part of a prospective AV development is communication over cars and infrastructure(connected vehicles). A major knowledge gap exists in AVtechnology with respect to routing behaviors. Connectedvehicle technology provides a great opportunity to implement an efficient and intelligent routing system. To this end, we propose a conceptual navigation model based on a fleet of AVs that are centrally dispatched over a network seeking system optimization. This study contributes to the literature on two fronts:(i) it attempts to shed light on future opportunities as well as possible hurdles associated with AV technology; and(ii) it conceptualizes a navigation model for the AV which leads to highly efficient traffic circulations. | Saeed Asadi Bagloee Madjid Tavana Mohsen Asadi Tracey Oliver | 2016 | Journal of Modern Transportation2016，24，4： | 14 |
| 15 | Imaging biomarkers in Parkinson’s disease and Parkinsonian syndromes:current and emerging concepts显示文摘Two centuries ago in 1817,James Parkinson provided the first medical description of Parkinson’s disease,later refined by Jean-Martin Charcot in the mid-to-late 19th century to include the atypical parkinsonian variants(also termed,Parkinson-plus syndromes).Today,Parkinson’s disease represents the second most common neurodegenerative disorder with an estimated global prevalence of over 10 million.Conversely,atypical parkinsonian syndromes encompass a group of relatively heterogeneous disorders that may share some clinical features with Parkinson’s disease,but are uncommon distinct clinicopathological diseases.Decades of scientific advancements have vastly improved our understanding of these disorders,including improvements in in vivo imaging for biomarker identification.Multimodal imaging for the visualization of structural and functional brain changes is especially important,as it allows a‘window’into the underlying pathophysiological abnormalities.In this article,we first present an overview of the cardinal clinical and neuropathological features of,1)synucleinopathies:Parkinson’s disease and other Lewy body spectrum disorders,as well as multiple system atrophy,and 2)tauopathies:progressive supranuclear palsy,and corticobasal degeneration.A comprehensive presentation of wellestablished and emerging imaging biomarkers for each disorder are then discussed.Biomarkers for the following imaging modalities are reviewed:1)structural magnetic resonance imaging(MRI)using T1,T2,and susceptibilityweighted sequences for volumetric and voxel-based morphometric analyses,as well as MRI derived visual signatures,2)diffusion tensor MRI for the assessment of white matter tract injury and microstructural integrity,3)proton magnetic resonance spectroscopy for quantifying proton-containing brain metabolites,4)single photon emission computed tomography for the evaluation of nigrostriatal integrity(as assessed by presynaptic dopamine transporters and postsynaptic dopamine D2 receptors),and cerebral perfusion,5)positron emission tomography for gauging nigrostriatal functions,glucose metabolism,amyloid and tau molecular imaging,as well as neuroinflammation,6)myocardial scintigraphy for dysautonomia,and 7)transcranial sonography for measuring substantia nigra and lentiform nucleus echogenicity.Imaging biomarkers,using the‘multimodal approach’,may aid in making early,accurate and objective diagnostic decisions,highlight neuroanatomical and pathophysiological mechanisms,as well as assist in evaluating disease progression and therapeutic responses to drugs in clinical trials. | Usman Saeed Jordana Compagnone Richard I.Aviv Antonio P.Strafella Sandra E.Black Anthony E.Lang Mario Masellis | 2017 | Translational Neurodegeneration2017，6，1： | 13 |

| 17 | Prevalence of gastric varices and results of sclerotherapy with N-butyl 2 cyanoacrylate for controlling acute gastric variceal bleeding显示文摘AIM: To study the prevalence, predictors and control of bleeding following N-butyl 2 cyanoacrylate (NBC) sclerotherapy of gastric varix (GV). METHODS: We analyzed case records of 1436 patients with portal hypertension, who underwent endoscopy during the past five years for variceal screening or upper gastrointestinal (GI) bleeding. Fifty patients with bleeding GV underwent sclerotherapy with a mean of 2 mL NBC for control of bleeding. Outcome parameters were primary hemostasis (bleeding control within the first 48 h), recurrent bleeding (after 48 h of esophago- gastro-duodenoscopy) and in-hospital mortality were analyzed. RESULTS: The prevalence of GV in patients with portal hypertension was 15% (220/1436) and the incidence of bleeding was 22.7% (50/220). Out of the 50 bleeding GV patients, isolated gastric varices (IGV-I) were seen in 22 (44%), gastro-oesophageal varices (GOV) on lesser curvature (GOV-Ⅰ) in 16 (32%), and GOV on greater curvature (GOV-Ⅱ) in 15 (30%). IGV-Ⅰ was seen in 44% (22/50) patients who had bleeding as compared to 23% (39/170) who did not have bleeding (P < 0.003). Primary hemostasis was achieved with NBC in all patients. Re-bleeding occurred in 7 (14%) patients after 48 h of initial sclerotherapy. Secondary hemostasis was achieved with repeat NBC sclerotherapy in 4/7 (57%). Three patients died after repeat sclerotherapy, one during transjugular intrahepatic portosystemic stem shunt (TIPSS), one during surgery and one due to uncontrolled bleeding. Treatment failure-related mortality rate was 6% (3/50). CONCLUSION: GV can be seen in 15% of patients withportal hypertension and the incidence of bleeding is 22.7%. NBC is highly effective in controlling GV bleeding. In hospital mortality of patients with bleeding GV is 6%. | Khalid Mumtaz Shahid Majid Hasnain A Shah Kashif Hameed Ashfaq Ahmed Saeed Hamid Wasim Jafri | 2007 | World Journal of Gastroenterology2007，13，8： | 12 |
| 18 | Photocatalytic degradation of methylene blue by nanostructured Fe/FeS powder under visible light显示文摘The photocatalytic performance of mechano-thermally synthesized Fe/FeS nanostructures formed from micron-sized starting materials was compared with that of a thermally synthesized nanostructure with nano-sized precursors in this paper. The properties of as-synthesized materials were studied by X-ray diffraction(XRD), transmission electron microscopy(TEM), vibrating sample magnetometry(VSM), diffuse reflectance spectroscopy(DRS), and ultraviolet–visible(UV-Vis) spectroscopy. The effects of irradiation time, methylene blue(MB) concentration, catalyst dosage, and p H value upon the degradation of MB were studied. Magnetic properties of the samples showed that both as-synthesized Fe/FeS photocatalysts are magnetically recoverable, eliminating the need for conventional filtration steps. Degradation of 5 ppm of the MB solution by mechano-thermally synthesized Fe/FeS with a photocatalyst dosage of 1 kg/m^3 at pH 11 can reach 96% after 12 ks irradiation under visible light. The photocatalytic efficiency is higher in alkaline solution. The kinetics of photocatalytic degradation in both samples is controlled by a first-order reaction. However, the rate-constant value in the thermally synthesized Fe/FeS photocatalyst sample is only 1.5 times greater than that of the mechano-thermally synthesized one. | Hassan Esmaili Amir Kotobi Saeed Sheibani Fereshteh Rashchi | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，2： | 11 |

| 20 | Evaluation of photosynthesis, physiological, and biochemical responses of chickpea (Cicer arietinum L. cv. Pirouz) under water deficit stress and use of vermicompost fertilizer显示文摘One goal in the face of drought stress conditions is to increase growth and yield through the reduction of negative effects of stress. Vermicompost can play an effective role in plant growth and development and in reducing harmful effects of various environmental stresses on plants due to its porous structure, high water storage capacity, having hormone-like substances, plant growth regulators, and high levels of macro and micro nutrients. This study considered the physiological, biochemical, and photosynthetic responses of the chickpea to different combinations of vermicompost and water stress in a greenhouse environment. Two factors were involved, addition of vermicompost to soil at four ratios: control(100 wt%(weight percentage) soil); 10 wt% vermicompost+90% soil; 20 wt% vermicompost+80 wt% soil; 30 wt% vermicompost+70 wt% soil weight percentage, and treatment of water stress at three levels including 75, 50, and 25% of field capacity. The results showed that vermicompost had a significant effect on all traits under stress and non-stress conditions. Application of vermicompost in soil, especially at the levels of 20 and 30 wt% significantly increased all studied traits under non-stress conditions. Under moderate stress conditions, vermicompost at 30 wt% treatment resulted in a significant increase in the photosynthetic pigments, CO_2 assimilation rate, internal leaf CO_2 concentration, transpiration, the maximal quantum yield of photosystem II(PSII) photochemistry(F_v/F_m), concentrations of Ca and K in root and leaf tissues, proline and soluble protein contents in root tissues. Peroxidase(POX) and catalase(CAT) enzyme activities decreased significantly with increasing proportions of vermicompost, but the activity of superoxide dismutase was not significantly different. In conclusion, the above results showed that vermicompost fertilizer had a positive effect on physiological, biochemical, and photosynthetic responses of chickpea under non-stress and moderate stress conditions, but no positive effect was determined under severe water stress. | Saeed Reza Hosseinzadeh Hamzeh Amiri Ahmad Ismaili | 2018 | Journal of Integrative Agriculture2018，17，11： | 9 |
