2Antidepressants can treat inflammatory bowel disease through regulation of the nuclear factor-κB/nitric oxide pathway and inhibition of cytokine production:A hypothesis显示文摘Inflammatory bowel disease (IBD) is a group of inflammatory disorders mainly affecting the colon and small intestine. The main types of IBD are Crohn’s disease (CD) and ulcerative colitis (UC). UC is restricted to the large intestine whereas CD can affect any part of the gastrointestinal tract. Treating this disorder depends on the form and level of severity. Common treatment involves an anti-inflammatory drug, such as mesalazine, and an immunosuppressant, such as prednisone. Several signaling pathways, including nuclear factor (NF)-κB and nitric oxide (NO), and genetic and environmental factors are believed to play an important role in IBD. Amitriptyline is a commonly used antidepressant with known anti-inflammatory activities. Amitriptyline also acts on the NF-κB/NO pathway or cytokine production. Therefore, we hypothesize that antidepressants like amitriptyline can be pioneered and considered effective as an innovative and effective therapeutic in the treatment and attenuation of development of IBD in adjusted doses.Hamid Reza Rahimi Mahdi Shiri Ali Razmi 2012World Journal of Gastrointestinal Pharmacology and Therapeutics2012,3,6:6
3焊丝对工业纯铜和304不锈钢钨极氩弧焊接的影响(英文)显示文摘采用不同焊丝对工业纯铜和304不锈钢进行钨极氩弧焊接。结果表明,采用铜做焊丝时,焊缝无任何缺陷生成,而采用304不锈钢和Ni-Cu-Fe合金为焊丝材料时,焊缝中有凝固裂纹和未熔化区存在。在最优条件下,焊缝的抗拉强度能达到铜材的96%。焊缝在弯曲到180°下也没有分离、撕裂和断裂等现象发生。这表明铜是一种较好的工业纯铜与304不锈钢GTA焊的焊丝材料。Sajjad Gholami SHIRI Mohsen NAZARZADEH Mahmood SHARIFITABAR Mehdi Shafiee AFARANI 2012Transactions of Nonferrous Metals Society of China2012,22,12:5

8Treatment with dimethyl fumarate ameliorates liver ischemia/reperfusion injury显示文摘AIM To investigate the hypothesis that treatment with dimethyl fumarate(D MF) mayame liorate liver ischemia/reperfusion injury(I/RI).METHODS Rats were divided into 3 groups: sham, control(CTL), and DMF. DMF(25 mg/kg, twice/d) was orally administered for 2 d before the procedure. The CTL and DMF rats were subjected to ischemia for 1 h and reperfusion for 2 h. The serum alanine aminotransferase(ALT) and malondialdehyde(MDA) levels, adenosine triphosphate(ATP), NO × metabolites, anti-oxidant enzyme expression level, antiinflammatory effect, and anti-apoptotic effect were determined.RESULTS Histological tissue damage was significantly reduced in the DMF group(Suzuki scores: sham: 0 ± 0; CTL: 9.3± 0.5; DMF: 2.5 ± 1.2; sham vs CTL, P < 0.0001; CTL vs DMF, P < 0.0001). This effect was associated with significantly lower serum ALT(DMF 5026 ± 2305 U/L vs CTL 10592 ± 1152 U/L, P = 0.04) and MDA(DMF 18.2 ± 1.4 μmol/L vs CTL 26.0 ± 1.0 μmol/L, P = 0.0009). DMF effectively improved the ATP content(DMF 20.3 ± 0.4 nmol/mg vs CTL 18.3 ± 0.6 nmol/mg, P = 0.02), myeloperoxidase activity(DMF 7.8 ± 0.4 m U/m L vs CTL 6.0 ± 0.5 m U/m L, P = 0.01) and level of endothelial nitric oxide synthase expression(DMF 0.38 ± 0.05-fold vs 0.17 ± 0.06-fold, P = 0.02). The higher expression levels of anti-oxidant enzymes(catalase and glutamatecysteine ligase modifier subunit and lower levels of key inflammatory mediators(nuclear factor-kappa B and cyclooxygenase-2 were confirmed in the DMF group.CONCLUSION DMF improved the liver function and the anti-oxidant and inflammation status following I/RI. Treatment with DMF could be a promising strategy in patients with liver I/RI.Chie Takasu Nosratola D Vaziri Shiri Li Lourdes Robles Kelly Vo Mizuki Takasu Christine Pham Seyed H Farzaneh Mitsuo Shimada Michael J Stamos Hirohito Ichii 2017World Journal of Gastroenterology2017,23,25:3
9在电休克治疗中重复间歇使用依托咪酯不会造成持久的肾上腺皮质功能抑制显示文摘依托咪酯作为一种麻醉诱导用药,在20世纪80年代开始用于危重症患者机械通气的镇静。然而Ledingham等1983年在柳叶刀的报道指出:接受依托咪酯治疗的患者死亡率远高于未接受此治疗的同类患者。此后一系列相关研究阐明了其机制并导致此项应用的终止。多项研究表明依托咪酯会抑制肾上腺皮质功能,即使单次剂量也可造成此抑制,虽然单次剂量的抑制是短暂的。Philip Lebowitz Susan Cohen Shiry Weisberg Bernard Wyszynski Charles Ramesar Peter Pfeiffer 2013临床麻醉学杂志2013,29,6:2
10Severe acute respiratory syndrome coronavirus 2 infection: Role of interleukin-6 and the inflammatory cascade显示文摘Since December 2019,a novel coronavirus that represents a serious threat to human lives has emerged.There is still no definite treatment for severe cases of the disease caused by this virus,named coronavirus disease 2019(COVID-19).One of the most considered treatment strategies targets the exaggerated immune regulator,and interleukin(IL)-6 is a crucial pro-inflammatory mediator.Severe acute respiratory syndrome coronavirus 2(SARSCoV-2)cases show an elevated level of IL-6 related to disease severity.IL-6 activity can be inhibited by the following:IL-6 itself,IL-6 signaling pathways such as Janus kinase and signal transducer and activator of transcription(JAK-STAT),gp130,IL-6R,and downstream activated ILs,such as IL-17 and IL-6 cytokine.Currently,according to these studies and their results,IL-6 blockade with anti-IL-6 or its receptor antibodies such as tocilizumab in COVID-19 is beneficial in severe cases and may reduce the mortality rate.JAK-STAT inhibitors block the cytokine storm by inhibiting several crucial pro-inflammatory mediators such as TNF-αand IL-6 and have shown various results in clinical trials.IL-6 induces IL-17 secretion,and IL-17 is involved in the pathogenesis of inflammatory processes.Clinical trials of anti-IL-17 drugs are currently recruiting,and anti-gp130 antibody is preclinical.However,this agent has shown positive effects in inflammatory bowel disease clinical trials and could be tested for SARS-CoV-2.This study aimed to review the role of IL-6 in the cytokine storm and studies regarding IL-6 and blockade of its inflammatory pathways in COVID-19 to determine if any of these agents are beneficial for COVID-19 patients.Mohaddeseh Bahmani Rojin Chegini Elham Ghanbari Elham Sheykhsaran Parisa Shiri Aghbash HamedEbrahimzadeh Leylabadlo Ehsan Moradian Amir Masoud Kazemzadeh Houjaghan Hossein Bannazadeh Baghi 2022World Journal of Virology2022,11,3:2

12采用铸造-倾析-铸造技术制备A390/A356铝合金功能梯度复合材料时过热和凝固层厚度对其界面接合的影响(英文)显示文摘铸造-倾析-铸造技术是近年来发展起来的一种制备功能梯度材料的新方法。采用这种方法制备在径向具有梯度功能的圆柱形试样,其外表层为具有高耐磨性的A390铝合金,芯部为具有较高韧性和加工性能的A356铝合金。研究芯部熔体在不同过热温度(750,820和860°C)和表层在不同倾析时间(25,35和45 s)下的A390/A356合金界面接合情况。采用光学显微镜和扫描电镜对界面进行表征,对界面区的显微硬度进行测量。结果表明,在过热温度为860°C,倾析时间为35 s的条件下,可以获得一宽度约为500μm的接合良好的界面层。比较了试样表面层和芯部的耐磨性能。M.MOHAMMADI RAHVARD M.TAMIZIFAR M.A.BOUTORABI S.GHOLAMI SHIRI 2014Transactions of Nonferrous Metals Society of China2014,24,3:2

17Endogenous fungal endophthalmitis:risk factors,clinical course,and visual outcome in 13 patients显示文摘AIM:To analyze the risk factors,ophthalmological features,treatment modalities and their effect on the visual outcome in patients with endogenous fungal endophthalmitis(EFE).METHODS:Data retrieved from the medical files included age at presentation to the uveitis clinic,gender,ocular symptoms and their duration before presentation,history of fever,eye affected,anatomical diagnosis and laboratory evidence of fungal infection.Medical therapy recorded included systemic antifungal therapy and its duration,use of intravitreal antifungal agents and use of oral/intravitreal steroids.Surgical procedures and the data of ophthalmologic examination at presentation and at last follow-up were also collected.RESULTS:Included were 13 patients(20 eyes,mean age 58 y).Ten patients presented after gastrointestinal or urological interventions and two presented after organ transplantation.In one patient,there was no history of previous intervention.Diagnostic vitrectomy was performed in 16 eyes(80%)and vitreous cultures were positive in 10 of the vitrectomized eyes(62.5%).In only 4 patients(31%),blood cultures were positive.All patients received systemic antifungal therapy.Sixteen eyes(80%)received intravitreal antifungal agent with voriconazole being the most commonly used.Visual acuity(VA)improved from 0.9±0.9 at initial exam to 0.5±0.8 logMAR at last followup(P=0.03).A trend of greater visual improvement was noted in favor of eyes treated with oral steroids(±intravitreal dexamethasone)than eyes that were not treated with steroids.The most common complication was maculopathy.Twelve eyes(60%)showed no ocular complications.CONCLUSION:High index of suspicion in patients with inciting risk factors is essential because of the low yield of blood cultures and the good general condition of patients at presentation.Visual prognosis is improved with the prompt institution of systemic and intravitreal pharmacotherapy and the immediate surgical intervention.Oral±local steroids could be considered in cases of prolonged or marked inflammatory responses in order to hasten control of inflammation and limit ocular complications.Jamel Corredores Itzhak Hemo Tareq Jaouni Zohar Habot-Wilner Michal Kramer Shiri Shulman Haneen Jabaly-Habib Ala'a Al-Talbishi Michael Halpert Edward Averbukh Jaime Levy Iris Deitch-Harel Radgonde Amer 2021International Journal of Ophthalmology(English edition)2021,14,1:1
