| 6 | Implication of altered proteasome function in alcoholic liverinjury显示文摘The proteasome is a major protein-degrading enzyme, which catalyzes degradation of oxidized and aged proteins, signal transduction factors and cleaves peptides for antigen presentation. Proteasome exists in the equilibrium of 26S and 20S particles. Proteasome function is altered by ethanol metabolism, depending on oxidative stress levels: low oxidative stress induces proteasome activity, while high oxidative stress reduces it. The proposed mechanisms for modulation of proteasome activity are related to oxidative modification of proteasomal proteins with primary and secondary products derived from ethanol oxidation. Decreased proteolysis by the proteasome results in the accumulation of insoluble protein aggregates, which cannot be degraded by proteasome and which further inhibit proteasome function. Mallory bodies, a common signature of alcoholic liver diseases, are formed by liver cells, when proteasome is unable to remove cytokeratins. Proteasome inhibition by ethanol also promotes the accumulation of pro-apoptotic factors in mitochondria of ethanol-metabolizing liver cells that are normally degraded by proteasome. In addition, decreased proteasome function also induces accumulation of the negative regulators of cytokine signaling (I-kB and SOCS), thereby blocking cytokine signal transduction. Finally, ethanol-elicited blockade of interferon type 1 and 2 signaling and decreased proteasome function impairs generation of peptides for MHC class Ⅰ-restricted antigen presentation. | Natalia A Osna Terrence M Donohue Jr | 2007 | World Journal of Gastroenterology2007，13，37： | 10 |
| 7 | Mycophenolate mofetil for drug-induced vanishing bile duct syndrome显示文摘Amoxicillin/clavulanate is associated with liver injury, mostly of a cholestatic pattern. While outcomes are usually benign, progression to cirrhosis and death has been reported. The role of immunosuppressive therapy for patients with a protracted course is unclear. We report the case of an elderly patient who developed prolonged cholestasis secondary to amoxicillin/clavulanate. Vanishing bile duct syndrome was confirmed by sequential liver biopsies. The patient responded to prednisone treatment, but could not be weaned off corticosteroids, even when azathioprine was added. Complete withdrawal of both prednisone and azathioprine was possible by using mycophenolate mofetil, an inosine monophosphate dehydrogenase inhibitor. Sustained remission has been maintained for more than 3 years with low-dose mycophenolate mofetil. | S Simona Jakab A Brian West Dennis M Meighan Robert S Brown Jr William B Hale | 2007 | World Journal of Gastroenterology2007，13，45： | 8 |
| 8 | 急性脊髓损伤患者治疗的临床操作指南:关于MRI基线在临床治疗决策与结果预测中作用的几点建议(英文)显示文摘The objective of this guideline is to outline the role of magnetic resonance imaging(MRI) in clinical decision making and outcome prediction in patients with traumatic spinal cord injury(SCI).Methods A systematic review of the literature was conducted to address key questions related to the use of MRI in patients with traumatic SCI.This review focused on longitudinal studies that controlled for baseline neurologic status.A multidisciplinary Guideline Development Group(GDG) used this information,their clinical expertise,and patient input to develop recommendations on the use of MRI for SCI patients.Based on GRADE(Grading of Recommendation,Assessment,Development and Evaluation),a strong recommendation is worded as ' we recommend,' whereas a weaker recommendation is indicated by 'we suggest.' Results Based on the limited available evidence and the clinical expertise of the GDG,our recommendations were:(1) 'We suggest that MRI be performed in adult patients with acute SCI prior to surgical intervention,when feasible,to facilitate improved clinical decision-making'(quality of evidence,very low) and(2) 'We suggest that MRI should be performed in adult patients in the acute period following SCI,before or after surgical intervention,to improve prediction of neurologic outcome '(quality of evidence,low).Conclusions These guidelines should be implemented into clinical practice to improve outcomes and prognostication for patients with SCI. | Fehlings MG Martin AR Tetreault LA Aarabi B Anderson P Arnold PM Brodke D Burns AS Chiba K Dettori JR Furlan JC Hawryluk G Holly LT Howley S Jeji T Kalsi-Ryan S Kotter M Kurpad S Kwon BK Marino RJ Massicotte E Merli G Middleton JW Nakashima H Nagoshi N Palmieri K Singh A Skelly AC Tsai EC Vaccaro A Wilson JR Yee A Harrop JS | 2017 | 中华神经外科疾病研究杂志2017，16，6： | 8 |
| 9 | Murine lung eosinophil activation and chemokine production in allergic airway inflammation显示文摘Eosinophils play important roles in asthma and lung infections.Murine models are widely used for assessing the functional significance and mechanistic basis for eosinophil involvements in these diseases.However,little is known about tissue eosinophils in homeostasis.In addition,little data on eosinophil chemokine production during allergic airway inflammation are available.In this study,the properties and functions of homeostatic and activated eosinophils were compared.Eosinophils from normal tissues expressed costimulation and adhesion molecules B7-1,B7-2 and ICAM-1 for Ag presentation but little major histocompatibility complex(MHC)class II,and were found to be poor stimulators of T-cell proliferation.However,these eosinophils expressed high levels of chemokine mRNA including C10,macrophage inflammatory protein(MIP)-1a,MIP-1c,MIP-2,eotaxin and monocyte chemoattractant protein-5(MCP-5),and produced chemokine proteins.Eosinophil intracellular chemokines decreased rapidly with concomitant surface marker downregulation upon in vitro culturing consistent with piecemeal degranulation.Lung eosinophils from mice with induced allergic airway inflammation exhibited increased chemokines mRNA expression and chemokines protein production and upregulated MHC class II and CD11c expression.They were also found to be the predominant producers of the CCR1 ligands CCL6/C10 and CCL9/MIP-1c in inflamed lungs.Eosinophil production of C10 and MIP-1c correlated with the marked influx of CD11bhigh lung dendritic cells during allergic airway inflammation and the high expression of CCR1 on these dendritic cells(DCs).The study provided baseline information on tissue eosinophils,documented the upregulation of activation markers and chemokine production in activated eosinophils,and indicated that eosinophils were a key chemokine-producing cell type in allergic lung inflammation. | C Edward Rose Jr Joanne A Lannigan Paul Kim James J Lee Shu Man Fu Sun-sang J Sung | 2010 | Cellular & Molecular Immunology2010，7，5： | 6 |
| 10 | Soil boron fertilization:The role of nutrient sources and rootstocks in citrus production显示文摘Boron(B) is a key element for citrus production, especially in tropical regions, where the nutrient availability is commonly low in the soil. In addition, information about doses, fertilizer sources, methods of application, and particularly, differential nutrient demand of scion/rootstock combinations are required for efficient fertilization of commercial groves. In a non-irrigated sweet orange orchard(cv. Natal), grafted onto Rangpur lime, Swingle citrumelo or Sunki mandarin, we studied the application of two sources of B: boric acid(17% B, soluble in water) and ulexite(12% B, partially soluble in water) at four levels of supply(control without B, and soil application of 2, 4 and 6 kg ha^(-1) yr^(-1) of B). The experiment was carried out for three years(2004-2006). Boron availability in the soil and concentration in the leaves, as well as the fruit yield and quality of trees were evaluated. Soil B extracted with hot water and total leaf B positively correlated with doses of the nutrient applied to the trees. Levels of B in the soil and in the leaves did not vary with fertilizer sources. Fruit yield of trees grafted onto Rangpur lime and Swingle citrumelo was more responsive to B doses than those grafted onto Sunki mandarin. The maximum fruit yield of trees grafted onto Swingle was obtained with 3.2 kg ha^(-1) yr^(-1) of B, and leaf B level of 280 mg kg^(-1) that point out to a highest demand for B when this combination was compared with other rootstocks. Furthermore, fertilization with B did not affect the quality of fruits, but correlated with B and potassium(K) concentrations in the leaves. These results also support that the current recommendations for levels of B in leaves should be revisited. | Dirceu Mattos Jr Franz W R Hippler Rodrigo M Boaretto Eduardo S Stuchi Jose A Quaggio | 2017 | Journal of Integrative Agriculture2017，16，7： | 5 |

| 12 | 视神经脊髓炎IgG刺激原代培养大鼠星形胶质细胞免疫反应显示文摘视神经脊髓炎(NMO)主要累及星形胶质细胞,导致中枢神经系统炎症、脱髓鞘和组织损伤。脑内病灶常高表达水通道蛋白4(AQP4),AQP4被认为是NMO血清IgG的抗原目标。根据NMO的可逆性及对NMO病灶演变特点的分析,笔者推测NMO IgG可能诱导了星形胶质细胞的动态免疫过程。培养原代大鼠星形胶质细胞,加入从NMO患者血清中提取或纯化的IgG,星形胶质细胞出现炎性增殖,同时基因表达出现与之匹配的明显变化。且星形胶质细胞反应因子脂质运载蛋白-2、多种趋化因子、细胞因子、应激反应因子的表达均增加。而在培养的原代星形胶质细胞中加入从正常对照者血清中提取的IgG则无上述变化。此星形胶质细胞的反应还与疾病种类相关。从复发缓解型多发硬化、Sj觟gren's或系统性红斑狼疮患者血清中提取的IgG加入培养的原代星形胶质细胞中也不能导致上述变化。笔者推测是NMO IgG与AQP4结合,导致星形胶质细胞出现炎症反应,并出现基因在转录和翻译水平的相应变化。抑制星形胶质细胞的炎症反应可能有助于减少星形胶质细胞增殖,缓解NMO病灶的发展。 | Howe CL Kaptzan T Magaa SM Ayers-Ringler JR LaFrance-Corey RG Lucchinetti CF | 2014 | 神经损伤与功能重建2014，9，3： | 4 |
| 13 | Effect of Helicobacter pylori cdrA on interleukin-8 secretions and nuclear factor kappa B activation显示文摘AIM:To investigate genetic diversity of Helicobacter pylori (H.pylori) cell division-related gene A (cdrA) and its effect on the host response.METHODS:Inactivation of H.pylori cdrA,which is involved in cell division and morphological elongation,has a role in chronic persistent infections.Genetic property of H.pylori cdrA was evaluated using polymerase chain reaction and sequencing in 128 (77 American and 51 Japanese) clinical isolates obtained from 48 and 51 patients,respectively.Enzyme-linked immunosorbent assay was performed to measure interleukin-8 (IL-8) secretion with gastric biopsy specimens obtained from American patients colonized with cdrA-positive or-negative strains and AGS cells cocultured with wild-type HPK5 (cdrA-positive) or its derivative HPKT510 (cdrA-disruptant).Furthermore,the cytotoxin-associated gene A (cagA) status (translocation and phosphorylation) and kinetics of transcription factors [nuclear factor-kappa B (NF-κB) and inhibition kappa B] were investigated in AGS cells co-cultured with HPK5,HPKT510 and its derivative HPK5CA (cagA disruptant) by western blotting analysis with immunoprecipitation.RESULTS:Genetic diversity of the H.pylori cdrA gene demonstrated that the cdrA status segregated into two categories including four allele types,cdrA-positive (allele types;Ⅰand Ⅱ) and cdrA-negative (allele types;Ⅲ and Ⅳ) categories,respectively.Almost all Japanese isolates were cdrA-positive (Ⅰ:7.8% and Ⅱ:90.2%),whereas 16.9% of American isolates were cdrA-positive (Ⅱ) and 83.1% were cdrA-negative (Ⅲ:37.7% and Ⅳ:45.5%),indicating extended diversity of cdrA in individual American isolates.Comparison of each isolate from different regions (antrum and corpus) in the stomach of 29 Americans revealed that cdrA status was identical in both isolates from different regions in 17 cases.However,12 cases had a different cdrA allele and 6 of them exhibited a different cdrA category between two regions in the stomach.Furthermore,in 5 of the 6 cases possessing a different cdrA category,cdrA-negative isolate existed in the corpus,suggesting that cdrA-negative strain is more adaptable to colonization in the corpus.IL-8 secretions from AGS revealed that IL-8 levels induced by a cdrA-disrupted HPKT510 was significantly lower (P < 0.01) compared to wildtype HPK5:corresponding to 50%-60% of those of wild-type HPK5.These data coincided with in vivo data that an average value of IL-8 in biopsy specimens from cdrA-positive and cdrA-negative groups was 215.6 and 135.9 pg/mL,respectively.Western blotting analysis documented that HPKT510 had no effect on CagA translocation and phosphorylation,however,nuclear accumulation of NF-κB was lower by HPKT510 compared to HPK5.CONCLUSION:Colonization by a cdrA-negative or cdrA-dysfunctional strain resulted in decreased IL-8 production and repression of NF-κB,and hence,attenuate the host immunity leading to persistent infection. | Hiroaki Takeuchi Ya-Nan Zhang Dawn A Israel Richard M Peek Jr Mikio Kamioka Hideo Yanai Norihito Morimoto Tetsuro Sugiura | 2012 | World Journal of Gastroenterology2012，18，5： | 3 |
| 14 | Animal models of ex vivo lung perfusion as a platform for transplantation research显示文摘Ex vivo lung perfusion(EVLP) is a powerful experimental model for isolated lung research. EVLP allows for the lungs to be manipulated and characterized in an external environment so that the effect of specific ventilation/perfusion variables can be studied independent of other confounding physiologic contributions. At the same time,EVLP allows for normal organ level function and real-time monitoring of pulmonary physiology and mechanics. As a result,this technique provides uniqueadvantages over in vivo and in vitro models. Small and large animal models of EVLP have been developed and each of these models has their strengths and weaknesses. In this manuscript,we provide insight into the relative strengths of each model and describe how the development of advanced EVLP protocols is leading to a novel experimental platform that can be used to answer critical questions in pulmonary physiology and transplant medicine. | Kevin Nelson Christopher Bobba Samir Ghadiali Don Hayes Jr Sylvester M Black Bryan A Whitson | 2014 | World Journal of Experimental Medicine2014，4，2： | 2 |

| 18 | Impaired swallowing mechanics of post radiation therapy head and neck cancer patients: A retrospective videofluoroscopic study显示文摘AIM: To determine swallowing outcomes and hyolaryngeal mechanics associated with post radiation therapy head and neck cancer(rt HNC) patients using videofluoroscopic swallow studies. METHODS: In this retrospective cohort study, video-fluoroscopic images of rt HNC patients(n = 21) were compared with age and gender matched controls(n = 21). Penetration-aspiration of the bolus and bolus residue were measured as swallowing outcome variables. Timing and displacement measurements of the anterior and posterior muscular slings elevating the hyolaryngeal complex were acquired. Coordinate data of anatomical landmarks mapping the action of the anterior muscles(suprahyoid muscles) and posterior muscles(long pharyngeal muscles) were used to calculate the distance measurements, and slice numbers were used to calculate time intervals. Canonical variate analysis with post-hoc discriminant function analysis was performed on coordinate data to determine multivariate mechanics of swallowing associated with treatment. Pharyngeal constriction ratio(PCR) was also measured to determine if weak pharyngeal constriction is associated with post radiation therapy.RESULTS: The rt HNC group was characterized by poor swallowing outcomes compared to the control group in regards to: Penetration-aspiration scale(P < 0.0001), normalized residue ratio scale(NRRS) for the valleculae(P = 0.002) and NRRS for the piriform sinuses(P = 0.003). Timing and distance measurements of the anterior muscular sling were not significantly different in the two groups, whereas for the PMS time of displacement was abbreviated(P = 0.002) and distance of excursion was reduced(P = 0.02) in the rt HNC group. A canonical variate analysis shows a significant reduction in pharyngeal mechanics in the rt HNC group(P < 0.0001). The PCR was significantly higher in the test group than the control group(P = 0.0001) indicating reduced efficiency in pharyngeal clearance. CONCLUSION: Using videofluoroscopy, this study shows rt HNC patients have worse swallowing outcomes associated with reduced hyolaryngeal mechanics and pharyngeal constriction compared with controls. | William G Pearson Jr Alisa A Davidoff Zachary M Smith Dorothy E Adams Susan E Langmore | 2016 | World Journal of Radiology2016，8，2： | 2 |
