| 1 | Validation of nutritional risk index method against patientgenerated subjective global assessment in screening malnutrition in colorectal cancer patients显示文摘Objective:To validate malnutrition screening tool of nutrition risk index(NRI)against patient-generated subjective global assessment(PG-SGA)as a gold standard tool in colorectal cancer patients before radiotherapy.Methods:Nutritional status of 52 volunteer colorectal cancer patients with a mean age of 54.1±16.8 years who referred to radiotherapy center were assessed by PG-SGA(gold standard method)and NRI.Serum albumin levels of patients were determined by colorimetric method.A contingency table was used to determine the sensitivity,specificity,and predictive value of the NRI in screening patients at risk of malnutrition,in comparison with the PG-SGA in patients before radiotherapy.Results:The findings of PG-SGA and NRI showed that 52%and 45%of patients in our study were moderately or severely malnourished respectively.The NRI had a sensitivity of 66%and a specificity of 60%against PG-SGA.The positive predictive value was 64%and the negative predicative value was 62%.The agreement between NRI and PG-SGA was statistically insignificant(kappa=0.267;P>0.05).Conclusions:The findings of present study showed that the prevalence of malnutrition was high in patients with colorectal cancer.Moreover,NRI method had low sensitivity and specificity in assessing nutritional status of patients with cancer.It seems that the combination of anthropometric,laboratory parameters and a subjective scoring system may be helpful tools in screening of malnutrition in cancer patients. | Elnaz Faramarzi Reza Mahdavi Mohammad Mohammad-Zadeh Behnam Nasirimotlagh | 2013 | Chinese Journal of Cancer Research2013，25，5： | 23 |
| 2 | Effects of Royal Jelly Supplementation on Glycemic Control and Oxidative Stress Factors in Type 2 Diabetic Female:A Randomized Clinical Trial显示文摘Objective:It has been proposed that royal jelly has antioxidant properties and may improve oxidative stress and glycemic control.Therefore,we investigated the effects of royal jelly supplementation in diabetic females.Methods:In this pilot,parallel design randomized clinical trial,50 female volunteers with type2 diabetes were randomly allocated to the supplemented(25,cases)and placebo(25,cases)groups,based on random block procedure produced by Random Allocation Software,given a daily dose of 1,000 mg royal jelly soft gel or placebo,respectively,for 8 weeks.Before and after intervention,glycemic control indices,antioxidant and oxidative stress factors were measured.Results:After royal jelly supplementation,the mean fasting blood glucose decreased remarkably(163.05142.51 mg/dL vs.149.68±42.7 mg/dL).Royal jelly supplementation resulted in significant reduction in the mean serum glycosylated hemoglobin levels(8.67%±2.24%vs.7.05%±1.45%,P=0.001)and significant elevation in the mean insulin concentration(70.28±29.16 pmol/L vs.86.46±27.50 pmol/L,P=0.01).Supplementation significantly increased erythrocyte superoxidase dismutase and glutathione peroxidase activities and decreased malondialdehyde levels(P<0.05).At the end of study,the mean total antioxidant capacity elevated insignificantly in both groups.Conclusions:On the basis of our findings,it seems that royal jelly supplementation may be beneficial in controlling diabetes outcomes.Further studies with larger sample size are warranted. | Samira Pourmoradian Reza Mahdavi Majid Mobasseri Elnaz Faramarzi Mehrnoosh Mobasseri | 2014 | Chinese Journal of Integrative Medicine2014，20，5： | 9 |
| 3 | Application of Rice Husk Biochar for Achieving Sustainable Agriculture and Environment显示文摘This paper critically reviewed the current knowledge and challenges of rice husk biochar(RHB)production and its effects on soil properties,plant growth,immobilization of heavy metals,reduction of nutrient leaching and mitigation of greenhouse gas emissions.The characteristics of RHBs produced at various pyrolysis temperatures were discussed and compared to biochars derived from other agro-industrial wastes.RHBs produced at higher pyrolysis temperatures show lower hydrogen/carbon ratio,which suggests the presence of higher aromatic carbon compounds.The increase of pyrolysis temperature also results in production of RHBs with higher ash content,lower yield and higher surface area.RHB usually has higher silicon and ash contents and lower carbon content compared to biochars derived from other feedstocks at the same pyrolysis conditions.Although it depends on soil type,RHB application can improve soil organic carbon content,cation exchange capacity,available K concentration,bulk density and microbial activity.The effect of RHB on soil aggregation mainly depends on soil texture.The growth of different crops is also enhanced by application of RHB.RHB addition to soil can immobilize heavy metals and herbicides and reduce their bioavailability.RHB application shows a significant capacity in reduction of nitrate leaching,although its magnitude depends on the biochar application rate and soil biogeochemical characteristics.Use of RHB,especially in paddy fields,shows a promising mitigation effect on greenhouse gas(CH4,CO2 and N2O)emissions.Although RHB characteristics are also related to other factors such as pyrolysis heating rate and residence time,its performance for specific applications(e.g.carbon sequestration,pH amendment)can be manipulated by adjusting the pyrolysis temperature.More research is needed on long-term field applications of RHB to fully understand the advantages and disadvantages of RHB as a soil amendment. | Hossein Asadi Mohammad Ghorbani Mehran Rezaei-Rashti Sepideh Abrishamkesh Elnaz Amirahmadi Chen Chengrong Manouchehr Gorji | 2021 | Rice science2021，28，4： | 4 |
| 4 | 离子液体BmmimOAc催化2-芳氨基乙醇与二硫化碳一步缩合合成3-芳基-2-噻唑硫酮(英文)显示文摘噻唑硫酮因具有独特的生物活性,使其在医学和杂环化学等领域有着广泛的应用,从而引起了科研工作者的研究兴趣。本文以离子液体1-丁基-2,3-二甲基咪唑鎓醋酸盐(Bmmim OAc)为催化剂,2-芳氨基乙醇和二硫化碳为起始原料,一步缩合合成3-芳基-2-噻唑硫酮。以2-苯氨基乙醇和二硫化碳的反应为模型,考察了一系列离子液体的催化活性。发现只有阴离子为醋酸根的离子液体才具有催化活性,这可能是由醋酸根的碱性所导致的。在这些阴离子为醋酸根的离子液体中,Bmmim OAc的催化活性最高。以其为催化剂,系统考察了反应时间、反应温度、催化剂用量以及二硫化碳和2-苯氨基乙醇摩尔比对该反应的影响。得到最优的反应条件:反应时间6 h、反应温度130℃、10%的Bmmim OAc用量以及5:1的二硫化碳和2-苯氨基乙醇摩尔比。在该反应条件下,目标产物3-苯基-2-噻唑硫酮的收率达到了97%。以不同的2-芳氨基乙醇为原料,考察了该反应的普适性。结果表明无论是具有给电子基团、吸电子基团或较大空间位阻的2-芳氨基乙醇均可顺利地与二硫化碳反应生成相应的3-芳基-2-噻唑硫酮,且分离收率高达83%–95%。核磁共振波谱和质谱分析表明反应过程中Bmmim OAc的醋酸根阴离子可以自发地与二硫化碳反应生成硫代醋酸根阴离子,因此离子液体1-丁基-2,3-二甲基咪唑鎓硫代醋酸盐(Bmmim COS)可能是2-芳氨基乙醇和二硫化碳反应的催化剂。通过核磁共振波谱研究了Bmmim COS与反应底物2-苯氨基乙醇和二硫化碳之间的相互作用,发现Bmmim COS与2-苯氨基乙醇之间存在氢键相互作用。在反应过程中硫代醋酸根阴离子通过氢键作用活化2-苯氨基乙醇,从而促进反应高效进行。基于表征结果,提出了一个可能的反应机理。首先,Bmmim OAc自发地与二硫化碳反应生成Bmmim COS。然后,Bmmim COS中的硫代醋酸根阴离子通过氢键作用活化2-苯氨基乙醇。随后,活化的2-苯氨基乙醇与二硫化碳反应生成中间体。最后,中间体分子内环化生成目标产物3-苯基-2-噻唑硫酮。<正>2喀土穆大学教育学院化学系,思图曼406。 | 陈必华 ELAGEED Elnazeer H.M. 张永亚 高国华 | 2018 | 物理化学学报2018，34，8： | 3 |

| 6 | Comparison of exogenous melatonin versus placebo on sleep efficiency in emergency medicine residents working night shifts: A randomized trial显示文摘BACKGROUND: Sleep deprivation resulting from night shifts, is a major cause of burnout among physicians. Exogenous melatonin may improve sleep quality in night-shift workers. The study aims to compare the effectiveness of melatonin versus placebo on sleep effi ciency in emergency medicine(EM) residents. METHODS: A randomized, double-blind, replicated crossover trial was performed on EM residents. This study consisted of 4 phases within a month with intervention periods of 2 nights and washouts of 6 days. In our study, EM residents had nine-hour shifts on 6 consecutive days, 2 mornings, 2 evenings and 2 nights and then 2 days off. At the end of shifts' cycle, 24 EM residents were given 3 mg melatonin or placebo(12 in each arm of the study) for 2 consecutive nights after the second night shift with crossover to the other arm after a six-day off drug. This crossover intervention was repeated for two more another time. Finally, we created 48 cases and comparisons in each arm. Different items related to sleep quality were assessed and compared both within the same group and between the two groups. RESULTS: In the melatonin group, daytime sleepiness(calculated by Karolinska Sleep Scale) had a signifi cant reduction after taking the second dose of drug(P=0.003) but the same result was not observed when comparing the 2 groups. Mood status(calculated by Profile of Mood States) showed no remarkable difference between the 2 groups. CONCLUSION: Melatonin might have a limited benefi t on sleep quality in EM residents working night shifts. | Shcrvin Farahmand Masoume Vafaeian Elnaz Vahidi Atefeh Abdollahi Shahram Baghcri-Hariri Ahmad Reza Dehpour | 2018 | World Journal of Emergency Medicine2018，9，4： | 2 |

| 8 | Evaluation of factors affecting psychological morbidity in emergency medicine practitioners显示文摘BACKGROUND: Assessing and evaluating mental health status can provide educational planners valuable information to predict the quality of physicians' performance at work. These data can help physicians to practice in the most desired way. The study aimed to evaluate factors affecting psychological morbidity in Iranian emergency medicine practitioners at educational hospitals of Tehran.METHODS: In this cross sectional study 204 participants(emergency medicine residents and specialists) from educational hospitals of Tehran were recruited and their psychological morbidity was assessed by using a 28-question Goldberg General Health Questionnaire(GHQ-28). Somatization, anxiety and sleep disorders, social dysfunction and depression were evaluated among practitioners and compared to demographic and job related variables.RESULTS: Two hundreds and four participants consisting of 146(71.6%) males and 58(28.4%) females were evaluated. Of all participants, 55(27%) were single and 149(73%) were married. Most of our participants(40.2%) were between 30–35 years old. By using GHQ-28, 129(63.2%) were recognized as normal and 75(36.8%) suffered some mental health disorders. There was a signifi cant gender difference between normal practitioners and practitioners with disorder(P=0.02) while marital status had no significant difference(P=0.2). Only 19(9.3%) declared having some major mental health issue in the previous month.CONCLUSION: Females encountered more mental health disorders than male(P=0.02) and the most common disorder observed was somatization(P=0.006). | Mehdi Momeni Farshid Fahim Elnaz Vahidi Amir Nejati Morteza Saeedi | 2016 | World Journal of Emergency Medicine2016，7，3： | 2 |
| 9 | Analgesic effect of paracetamol combined with low- dose morphine versus morphine alone on patients with biliary colic: a double blind, randomized controlled trial显示文摘BACKGROUND:Numerous drugs have been proposed to alleviate pain in patients with biliary colic,especially opioids,but still there is a tendency to use less narcotics because of their side effects and the unwillingness of some patients.The present study aimed to compare the analgesic effect of paracetamol combined with low-dose morphine versus morphine alone in patients with biliary colic.METHODS:A randomized double-blind controlled trial was performed in 98 patients with biliary colic,recruited from two emergency departments from August 2012 to August 2013.Eleven patients were excluded and the remaining were randomized into two groups:group A received 0.05mg/kg morphine+1 000 mg paracetamol in 100 m L normal saline and group B received 0.1 mg/kg morphine+normal saline(100 m L)as placebo.Pain scores were recorded using visual analogue scale(VAS)at baseline and 15 and 30 minutes after drug administration.Adverse effects and the need for rescue medication(0.75 g/kg intravenous fentanyl)were also reported within 60 minutes of drug administration.RESULTS:Before the infusion,the mean±SD VAS scores were 8.73±1.57 in group A and8.53±1.99 in group B.At 15 minutes after drug administration,the mean±SD VAS scores were2.16±1.90 in group A vs.2.51±1.86 in group B;mean difference was–0.35,and 95%CI–1.15 to 0.45(P=0.38).At 30 minutes the mean±SD VAS scores were 1.66±1.59 in group A vs.2.14±1.79 in group B;mean difference was–0.48,and 95%CI–1.20 to 0.24(P=0.19).The mean pain scores in the two groups at 15 and 30 minutes demonstrated no significant difference.CONCLUSION:Paracetamol combined with low-dose morphine may be effective for pain management in patients with biliary colic. | Mohammad Reza Farnia Rasoul Babaei Farzaneh Shirani Mehdi Momeni Majid Hajimaghsoudi Elnaz Vahidi Morteza Saeedi | 2016 | World Journal of Emergency Medicine2016，7，1： | 2 |

| 16 | Comparison between intravenous morphine versus fentanyl in acute pain relief in drug abusers with acute limb traumatic injury显示文摘BACKGROUND: Rapid and effective pain relief in acute traumatic limb injuries(ATLI) is one of the most important roles of emergency physicians. In these situations, opioid addiction is an important concern because of the dependency on opioids. The study aims to compare the effectiveness of intravenous(IV) fentanyl versus morphine in reducing pain in patients with opioid addiction who suffered from ATLI.METHODS: In this double-blind randomized clinical trial, 320 patients with ATLI, who presented to the emergency department(ED) from February 2016 to April 2016, were randomly divided into two groups. One group(160 patients) received 0.1 mg/kg IV morphine. The other group(160 patients) received 1 mcg/kg IV fentanyl. Patients' demographic data, pain score at specif ic intervals, vital signs, side effects, satisfaction and the need for rescue analgesia were recorded.RESULTS: Eight patients in the morphine group and five patients in the fentanyl group were excluded. Pain score in the fentanyl group had a significant decrease at 5-minute follow-up(P value=0.00). However, at 10, 30, and 60-minute follow-ups no signifi cant differences were observed between the two groups in terms of pain score reduction. The rescue analgesia was required in 12(7.7%) patients in the fentanyl group and in 48(31.6%) patients in the morphine group(P value=0.00). No signifi cant difference was observed regarding side effects, vital signs and patients' satisfaction between the two groups.CONCLUSION: Fentanyl might be an effective and safe drug in opioid addicts suffering from ATLI. | Hojat Sheikh Motahar Vahedi Hadi Hajebi Elnaz Vahidi Amir Nejati Morteza Saeedi | 2019 | World Journal of Emergency Medicine2019，10，1： | 1 |

| 20 | Experimental evaluation of thiamine as a new clay swelling inhibitor显示文摘This study aims at evaluating the performance of thiamine as a new eco-friendly shale inhibitor in water-based drilling fluids(WBDFs).The evaluation experiments include sedimentation,bentonite inhibition,filtration,zeta potential,thermal gravimetric analysis,scanning electron microscopy,X-ray diffraction,shale cuttings recovery,linear swelling and Fourier transform infrared spectroscopy(FTIR).The performance of thiamine was compared to potassium chloride.In contrast to deionized water,the aqueous solution of thiamine exhibited greater power to inhibit montmorillonite(Mt)dispersion,much more Mt loading capacity(280 g/L)and fluid loss,lower Mt mass loss,larger aggregated Mt particles,lower interlayer space of the Mt particles,less shale cuttings disintegration and lower linear swelling.Adsorption of thiamine on Mt led to a significant shift in the value of zeta potential(from-17.1 to+8.54 mV).Thiamine demonstrated superior inhibitive performance than potassium chloride.FTIR analysis confirmed that thiamine is adsorbed on Mt particles.The compatibility test revealed the compatibility of thiamine with conventional WBDF additives.It was concluded that the main probable inhibition mechanisms of thiamine are the cation exchange and Mt surface coating.In view of its prominent inhibition capacity and great environmental acceptability,thiamine is a promising inhibitor for drilling in water-sensitive formations. | Saeed Parvizi Ghaleh Elnaz Khodapanah Seyyed Alireza Tabatabaei-Nezhad | 2020 | Petroleum Science2020，17，6： | 1 |
