| 1 | Antioxidant therapy in the management of acute,chronic and post-ERCP pancreatitis:A systematic review显示文摘We systematically reviewed the clinical trials which recruited antioxidants in the therapy of pancreatitis and evaluated whether antioxidants improve the outcome of patients with pancreatitis.Electronic bibliographic databases were searched for any studies which investigated the use of antioxidants in the management of acute pancreatitis(AP)or chronic pancreatitis(CP)and in the prevention of post-endoscopic retrograde cholangio-pancreatography(post-ERCP)pancreatitis(PEP)up to February 2009.Twenty-two randomized,placebo-controlled,clinical trials met our criteria and were included in the review.Except for a cocktail of antioxidants which showed improvement in outcomes in three different clinical trials,the results of the administration of other antioxidants in both AP and CP clinical trials were incongruent and heterogeneous.Furthermore,antioxidant therapy including allopurinol and N-acetylcysteine failed to prevent the onset of PEP in almost all trials.In conclusion,the present data do not support a benefit of antioxidant therapy alone or in combination with conventional therapy in the management of AP,CP or PEP.Further double blind,randomized,placebo-controlled clinical trials with large sample size need to be conducted. | Seyed Sajad Mohseni Salehi Monfared Hamed Vahidi Amir Hossein Abdolghaffari Shekoufeh Nikfar Mohammad Abdollahi | 2009 | World Journal of Gastroenterology2009，15，36： | 10 |
| 2 | Understanding divergent domestication traits from the whole-genome sequencing of swamp-and river-buffalo populations显示文摘Domesticated buffaloes have been integral to rice-paddy agro-ecosystems formillennia,yet relatively little is known about the buffalo genomics.Here,we sequenced and assembled reference genomes for both swamp and river buffaloes and we re-sequenced 230 individuals(132 swamp buffaloes and 98 river buffaloes)sampled from across Asia and Europe.Beyond the many actionable insights that our study revealed about the domestication,basic physiology and breeding of buffalo,we made the striking discovery that the divergent domestication traits between swamp and river buffaloes can be explained with recent selections of genes on social behavior,digestion metabolism,strengths and milk production. | Xier Luo Yu Zhou Bing Zhang Yi Zhang Xiaobo Wang Tong Feng Zhipeng Li Kuiqing Cui Zhiqiang Wang Chan Luo Hui Li Yanfei Deng Fenghua Lu Jianlin Han Yongwang Miao Huaming Mao Xiaoyan Yi Cheng Ai Shigang Wu Alun Li Zhichao Wu Zijun Zhuo Do Da Giang Bikash Mitra Mohammad Farhad Vahidi Shahid Mansoor Sahar Ahmed Al-Bayatti Eka Meutia Sari Neena Amatya Gorkhali Sigit Prastowo Laiba Shafique Guoyou Ye Qian Qian Baoshan Chen Deshun Shi Jue Ruan Qingyou Liu | 2020 | National Science Review2020，7，3： | 3 |
| 3 | 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 |
| 4 | 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 |
| 5 | A polymer electro-optic modulator with ultra wide-band and low driving voltage显示文摘In this paper, a polymer electro-optic modulator is designed and simulated using the full vectorial finite element method. First order edge elements are used in finite element implementation, and the finite element technique is used to obtain modulator response thoroughly. From the numerical analysis, frequency dispersions of modulator's important parameters, such as microwave effective index nm , microwave characteristic impedance ZC and microwave loss a, are extracted. Our design exhibits electrical bandwidth of 260 GHz and drive voltage of about 2.8 V.cm in this frequency. | Kambiz Abedi Habib Vahidi | 2011 | Optoelectronics Letters2011，7，6： | 2 |
| 6 | 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 |
