| 1 | Efficacy of premedication with activated Dimethicone or N-acetylcysteine in improving visibility during upper endoscopy显示文摘AIM:To assess the efficacy of N-acetylcysteine(NAC) and activated Dimethicone in improving endoscopic mucosal visibility.METHODS:A total of 148 patients were randomly allocated into four groups to receive one of the following premedications:group A:100 mL water alone;group B:activated Dimethicone plus water(up to 100 mL);group C:NAC plus water(up to 100 mL);and group D:activated Dimethicone and NAC plus water(up to 100 mL).A single endoscopist blinded to the patients group assessed the gastric mucosal visibility scores(range 1-4) at four sites.The sum of the scores from the four sites was considered as the total mucosal visibility score(TMVS).RESULTS:The patients in group B showed a significantly lower TMVS than those of groups A and C(P < 0.001).The TMVS in patients of group D was significantly lower than that of groups A and C(P < 0.001).The TMVS did not significantly differ between groups B and D(P > 0.05).The difference between TMVS of groups C and A was not significant(P > 0.05).CONCLUSION:Premedication with activated Dimethicone 20 min prior to the upper endoscopy leads to the best visibility.NAC does not improve visualization by itself. | Seyed Mohammad Kazem Hosseini Asl Gholam Reza Sivandzadeh | 2011 | World Journal of Gastroenterology2011，17，37： | 15 |

| 3 | Cyclic vomiting syndrome in children: Experience with 181 cases from southern Iran显示文摘AIM: To evaluate the clinical presentation, response to prophylactic therapy and outcome of children with cyclic vomiting syndrome (CVS) in Shiraz, Iran.METHODS: During a period of 11 years (March 1994 to March 2005), 181 consecutive children with a final diagnosis of CVS were evaluated, treated and followed in our center. Patients were randomized to receive either amitriptyline or propranolol as prophylactic treatments. RESULTS: There were 88 boys and 93 girls with mean age of onset of symptoms of 4.9 ± 3.3 years (range, neonatal period to 14 years), the mean age at final diagnosis was 6.9 years (range, 1.5 to 14), and the mean duration between the onset of the first attack and the final diagnosis of CVS was 2 ± 1.81 years (range, 1/6 to 8). The mean duration of each attack was 4.26 days (range, from few hours to 10 d) and the mean interval between the attacks was 1.8 mo (range, 1 wk to 12 mo). The time of onset of the attacks was midnight to early morning in about 70% of cases. Amitriptyline was effective in 46 out of 81 (56%) patients (P < 0.001). Propranolol appeared to have a superior action and was effective in 74 out of 83 (92%) patients (P < 0.0001).CONCLUSION: There is a significant lag time between the onset of clinical symptoms and the final diagnosis of CVS in our area. In patients with typical clinical presentations of CVS, who are examined by an experienced physician, invasive workup is not necessary. Propranolol appears more effective than amitriptyline for prophylactic use in children with CVS. | Mahmood Haghighat Seyed Mohammad Rafie Seyed Mohsen Dehghani Gholam Hossein Fallahi Marzieh Nejabat | 2007 | World Journal of Gastroenterology2007，13，12： | 11 |
| 4 | Oral manifestation in inflammatory bowel disease:A review显示文摘Inflammatory bowel diseases(IBDs),including Crohn’s disease(CD)and ulcerative colitis,not only affect the intestinal tract but also have an extraintestinal involvement within the oral cavity.These oral manifestations may assist in the diagnosis and the monitoring of disease activity,whilst ignoring them may lead to an inaccurate diagnosis and useless and expensive workups.Indurated tag-like lesions,cobblestoning,and mucogingivitis are the most common specific oral findings encountered in CD cases.Aphthous stomatitis and pyostomatitis vegetans are among non-specific oral manifestations of IBD.In differential diagnosis,side effects of drugs,infections,nutritional deficiencies,and other inflammatory conditions should also be considered.Treatment usually involves managing the underlying intestinal disease.In severe cases with local symptoms,topical and/or systemic steroids and immunosuppressive drugs might be used. | Kamran B Lankarani Gholam Reza Sivandzadeh Shima Hassanpour | 2013 | World Journal of Gastroenterology2013，19，46： | 10 |

| 6 | GIS-based spatial analysis of urban traffic accidents: Case study in Mashhad, Iran显示文摘There is a growing concern in traffic accident rate in recent years. Using Mashhad city(Iran second populous city) traffic accident records as case study, this paper applied the combination of geo-information technology and spatial-statistical analysis to bring out the influence of spatial factors in their formation. The aim of the study is to examine 4 clustering analyses to have a better understanding of traffic accidents patterns in complex urban network. In order to deploy the clustering technique in urban roads, 9331 point features for inner city traffic accidents during 12 months have been registered according to their x and y location in geographic information system(GIS). The mentioned areas were analyzed by kernel density estimation(KDE) using ARCMAP and two other analyses using SANET 4th edition software so that the results of network analysis can be compared with traditional KDE method. In addition, this research introduces five classifications for determining the eventfulness of the under study area based on standard deviation and to make priority in creating security in the area.The nearest neighbor and K-function output analysis consist of four curves and regarding the fact that for all fatal, injury and property damage only crashes, the observed value curve is above the 5% confidence interval. Accidents in the study region are more clustered than expected by random chance. The importance of this study is to use GIS as a management system for accident analysis by combination of spatial-statistical methods. | Gholam Ali Shafabakhsh Afshin Famili Mohammad Sadegh Bahadori | 2017 | Journal of Traffic and Transportation Engineering(English Edition)2017，4，3： | 8 |

| 9 | Extractive oxidative desulfurization of model oil/crude oil using KSF montmorillonite-supported 12-tungstophosphoric acid显示文摘12-Tungstophosphoric acid(PW) supported on KSF montmorillonite, PW/KSF, was used as catalyst for deep oxidative desulfurization(ODS) of mixed thiophenic compounds in model oil and crude oil under mild conditions using hydrogen peroxide(H_2O_2) as an oxidizing agent. A one-factor-at-a-time method was applied for optimizing the parameters such as temperature, reaction time, amount of catalyst, type of extractant and oxidant-tosulfur compounds(S-compounds) molar ratio. The corresponding products can be easily removed from the model oil by using ethanol as the best extractant. The results showed high catalytic activity of PW/KSF in the oxidative removal of dibenzothiophene(DBT) and mixed thiophenic model oil under atmospheric pressure at 75 ℃ in a biphasic system. To investigate the oxidation and adsorption effects of crude oil composition on ODS, the effects of cyclohexene, 1,7-octadiene and o-xylene with different concentrations were studied. | Ezzat Rafiee Sadegh Sahraei Gholam Reza Moradi | 2016 | Petroleum Science2016，13，4： | 6 |
| 10 | COVID-19 infection and liver injury:Clinical features,biomarkers,potential mechanisms,treatment,and management challenges显示文摘It is hypothesized that liver impairment caused by coronavirus disease 2019(COVID-19)infection might play a central role in severe clinical presentations.Liver injury is closely associated with severe disease and,even with antiviral drugs,have a poor prognosis in COVID-19 patients.In addition to the common hepatobiliary disorders caused by COVID-19,patients with pre-existing liver diseases demand special considerations during the current pandemic.Thus,it is vital that upon clinical presentation,patients with concurrent pre-existing liver disease associated with metabolic dysfunction and COVID-19 be managed properly to prevent liver failure.Careful monitoring and early detection of liver damage through biomarkers after hospitalization for COVID-19 is underscored in all cases,particularly in those with pre-existing metabolic liver injury.The purpose of this study was to determine most recent evidence regarding causality,potential risk factors,and challenges,therapeutic options,and management of COVID-19 infection in vulnerable patients with pre-existing liver injury.This review aims to highlight the current frontier of COVID-19 infection and liver injury and the direction of liver injury in these patients. | Gholam Reza Sivandzadeh Hassan Askari Ali Reza Safarpour Fardad Ejtehadi Ehsan Raeis-Abdollahi Armaghan Vaez Lari Mohammad Foad Abazari Firoozeh Tarkesh Kamran Bagheri Lankarani | 2021 | World Journal of Clinical Cases2021，9，22： | 5 |

| 12 | Analysis of dynamic wave model for flood routing in natural rivers显示文摘Flooding is a common natural disaster that causes enormous economic, social, and human losses. Of various flood routing methods, the dynamic wave model is one of the best approaches for the prediction of the characteristics of floods during their propagations in natural rivers because all of the terms of the momentum equation are considered in the model. However, no significant research has been conducted on how the model sensitivity affects the accuracy of the downstream hydrograph. In this study, a comprehensive analysis of the input parameters of the dynamic wave model was performed through field applications in natural rivers and routing experiments in artificial channels using the graphical multi-parametric sensitivity analysis (GMPSA). The results indicate that the effects of input parameter errors on the output results are more significant in special situations, such as lower values of Manning's roughness coefficient and/or a steeper bed slope on the characteristics of a design hydrograph, larger values of the skewness factor and/or time to peak on the channel characteristics, larger values of Manning's roughness coefficient and/or the bed slope on the space step, and lower values of Manning's roughness coefficient and/or a steeper bed slope on the time step and weighting factor. | Reza BARATI Sajjad RAHIMI Gholam Hossein AKBARI | 2012 | Water Science and Engineering2012，5，3： | 3 |

| 19 | A Cu-Cr alloy with nano and microscale Cr particles produced in a water-cooled copper mold显示文摘Microstructures have profound effects on the hardness and strength of Cu-Cr alloys. The microstructures of a Cu-Cr alloy cast in a water-cooled copper mold were studied in the present work. The scanning electron microscopy (SEM) results show that there are the copper matrix saturated with chromium, spherical precipitates of chromium separated from liquid phase during cooling before the initiation of so- lidification, and a eutectic phase in grain boundary areas. To investigate the effect of age-hardening treatment on the microstructures and properties of the material, some samples were subsequently age-hardened in a salt bath and investigated by transmission electron microscopy (TEM). The results show that coherent precipitates with the diameter of 11 nm are detectable in the samples before and after the age-hardening stage. Of course, the volume fraction of coherent precipitates is higher after the aging process. | Seyyed Mohammd Hossein Hejazi Fatemeh Majidi Gholam Hossein Akbari | 2010 | International Journal of Minerals,Metallurgy and Materials2010，17，5： | 2 |
