2Autophagy inhibition by chloroquine sensitizes HT-29 colorectal cancer cells to concurrent chemoradiation显示文摘AIM:To investigate whether the inhibition of autophagy by chloroquine(CQ)sensitizes rectal tumors to radiation therapy(RT)or concurrent chemoradiation(chemoRT).METHODS:In vitro,HCT-116 and HT-29 colorectal cancer(CRC)cell lines were treated as following:(1)PBS;(2)CQ;(3)5-fluorouracil(5-FU);(4)RT;(5)CQ and RT;(6)5-FU and RT;(7)CQ and 5-FU;and(8)5-FU and CQ and RT.Each group was then exposed to various doses of radiation(0-8 Gy)depending on the experiment.Cell viability and proliferative capacity were measured by3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)and clonogenic assays.Clonogenic survivalcurves were constructed and compared across treatment groups.Autophagy status was determined by assessing the LC3-Ⅱto LC3-Ⅰratio on western blot analysis,autophagosome formation on electron microscopy and identification of a perinuclear punctate pattern with GFPlabeled LC3 on fluorescence microscopy.Cell cycle arrest and cell death were evaluated by FACS and AnnexinⅤanalysis.All experiments were performed in triplicate and statistical analysis was performed by the student’s t test to compare means between treatment groups.RESULTS:RT(2-8 Gy)induced autophagy in HCT-116and HT-29 CRC cell lines at 4 and 6 h post-radiation,respectively,as measured by increasing LC3-Ⅱto LC3-Ⅰratio on western blot.Additionally,electron microscopy demonstrated autophagy induction in HT-29 cells24 h following irradiation at a dose of 8 Gy.Drug treatment with 5-FU(25μmol/L)induced autophagy and the combination of 5-FU and RT demonstrated synergism in autophagy induction.CQ(10μmol/L)alone and in combination with RT effectively inhibited autophagy and sensitized both HCT-116 and HT-29 cells to treatment with radiation(8 Gy;P<0.001 and 0.00001,respectively).Significant decrease in clonogenic survival was seen only in the HT-29 cell line,when CQ was combined with RT at doses of 2 and 8 Gy(P<0.5 and P=0.05,respectively).There were no differences in cell cycle progression or Annexin V staining upon CQ addition to RT.CONCLUSION:Autophagy inhibition by CQ increases CRC cell sensitivity to concurrent treatment with 5-FU and RT in vitro,suggesting that addition of CQ to chemoRT improves CRC treatment response.Caitlin A Schonewolf Monal Mehta Devora Schiff Hao Wu Bruce G Haffty Vassiliki Karantza Salma K Jabbour 2014World Journal of Gastrointestinal Oncology2014,6,3:12

6Osteoclast activity modulates B-cell development in the bone marrow显示文摘B 房间开发开是依赖的在 B 房间先锋和骨头髓 stromal 房间之间的相互作用,而是在这的骨破折(OCL ) 的角色处理未知的遗体。B lymphocytopenia 是 osteopetrosis 的一个特征,建议由 OCL 活动的 B 淋巴细胞增殖的调整。探讨这个问题,我们首先由树枝状的房间转移在 osteopetrotic oc/oc 鼠标救了 OCL 功能,导致骨头显型和 B 房间开发的恢复。为了推进,探索在 OCL 活动和 B 淋巴细胞增殖之间的连接,我们由 zoledronic 酸(ZA ) 的注射在正常老鼠导致了 osteopetrosis,骨头再吞的一个禁止者。B 房间数字在对待 ZA 的老鼠的骨头髓明确地减少了。ZA 直接没影响 B 房间区别,增长和 apoptosis,但是由 stromal 房间在 CXCL12 和 IL-7 的表示导致减少,与减少的 osteoblastic 约会联系了。在 oc/oc 老鼠的相等的低 osteoblastic 约会证实它在造骨细胞上源于减少的 OCL 活动而非从 ZA 的直接效果。骨头微型环境的这些戏剧的改变为 B 淋巴细胞增殖是不利的,导致在他们在导致 ZA 的 osteopetrotic 模型的骨头髓壁龛外面的 B 房间祖先的保留。总的来说,我们的数据表明 OCL 由控制骨头微型环境和造骨细胞的命运在骨头髓调制 B 房间开发。他们由 OCL 活动在他们的壁龛为 B 房间的保留的规定提供新奇基础。Anna Mansour 2011Cell Research2011,21,7:6
7Covert hepatic encephalopathy: Agreement and predictive validity of different indices显示文摘AIM:To investigate the agreement and prognosticvalue of different measures of covert hepatic encephalopathy(CHE).METHODS:One-hundred-and-thirty-two cirrhotic outpatients underwent electroencephalography(EEG),paper-and-pencil psychometry(PHES)and critical flicker frequency,scored on the original/modified(CFFo/CFFm)thresholds.Eighty-four patients underwent Dopplerultrasound to diagnose/exclude portal-systemic shunt.Seventy-nine were followed-up for 11±7 mo in relation to the occurrence of hepatic encephalopathy(HE)-related hospitalisations.RESULTS:On the day of study,36%had gradeⅠHE,42%abnormal EEG,33%abnormal PHES and 31/21%abnormal CFFo/CFFm.Significant associations were observed between combinations of test abnormalities;however,agreement was poor(Cohen’sκ<0.4).The prevalence of EEG,PHES and CFFo/CFFm abnormalities was significantly higher in patients with gradeⅠovert HE.The prevalence of EEG and CFFm abnormalities was higher in patients with shunt.The prevalence of EEG abnormalities was significantly higher in patients with a history of HE.During follow-up,10 patients died,10were transplanted and 29 had HE-related hospitalisations.GradeⅠHE(P=0.004),abnormal EEG(P=0.008)and abnormal PHES(P=0.04)at baseline all predicted the subsequent occurrence of HE;CFF did not.CONCLUSION:CHE diagnosis probably requires a combination of clinical,neurophysiological and neuropsychological indices.Sara Montagnese Esmeralda Balistreri Sami Schiff Michele De Rui Paolo Angeli Giacomo Zanus Umberto Cillo Giancarlo Bombonato Massimo Bolognesi David Sacerdoti Angelo Gatta Carlo Merkel Piero Amodio 2014World Journal of Gastroenterology2014,20,42:6
8Vascular depression for radiology: A review of the construct,methodology,and diagnosis显示文摘Vascular depression(VD)as defined by magnetic resonance imaging(MRI)has been proposed as a unique subtype of late-life depression.The VD hypothesis posits that cerebrovascular disease,as characterized by the presence of MRIdefined white matter hyperintensities,contributes to and increases the risk for depression in older adults.VD is also accompanied by cognitive impairment and poor antidepressant treatment response.The VD diagnosis relies on MRI findings and yet this clinical entity is largely unfamiliar to neuroradiologists and is rarely,if ever,discussed in radiology journals.The primary purpose of this review is to introduce the MRI-defined VD construct to the neuroradiology community.Case reports are highlighted in order to illustrate the profile of VD in terms of radiological,clinical,and neuropsychological findings.A secondary purpose is to elucidate and elaborate on the measurement of cerebrovascular disease through visual rating scales and semi-and fully-automated volumetric methods.These methods are crucial for determining whether lesion burden or lesion severity is the dominant pathological contributor to VD.Additionally,these rating methods have implications for the growing field of computer assisted diagnosis.Since VD has been found to have a profile that is distinct from other types of late-life depression,neuroradiologists,in conjunction with psychiatrists and psychologists,should consider VD in diagnosis and treatment planning.Sara N Rushia Al Amira Safa Shehab Jeffrey N Motter Dakota A Egglefield Sophie Schiff Joel R Sneed Ernst Garcon 2020World Journal of Radiology2020,12,5:5

11FibroSURE^(TM) and FibroScan~ in relation to treatment response in chronic hepatitis C virus显示文摘AIM:To compare histological endpoint assessment using noninvasive alternatives to biopsy during treatment in a chronic hepatitis C virus(HCV)cohort.METHODS:Patients with chronic HCV were randomized to receive interferon-based therapy for 24(genotypes 2/3)or 48(genotype 1)wk.FibroSURE~TM(FS)was assessed at baseline and at week-12 post-treatment follow-up.Baseline biopsy for METAVIR was assessed by a single pathologist.FibroScan~ transient elastogra-phy(TE)was performed during treatment in a patient subset.RESULTS:Two thousand and sixty patients(n = 253 in Asia)were classif ied as METAVIR F0-1(n = 1682)or F2-4(n = 378).For F2-4,FS(n = 2055)had sensitiv-ity and specif icity of 0.87 and 0.61,respectively,with area under the receiver-operating curve of 0.82;corre-sponding values for TE(n = 214)and combined FS/TE(n = 209)were 0.77,0.88 and 0.88,and 0.93,0.68 and 0.88.Overall FS/TE agreement for F2-4 was 71%(κ = 0.41)and higher in Asians vs non-Asians(κ = 0.86 vs 0.35;P < 0.001).Combined FS/TE had 97% accuracy in Asians(n = 33).Baseline FS(0.38 vs 0.51,P < 0.001)and TE(8.0 kPa vs 11.9 kPa,P = 0.006)scores were lower in patients with sustained virological response than in nonresponders,and were maintained through follow-up.CONCLUSION:FS and TE may reliably differentiate mild from moderate-advanced disease,with a potential for high diagnostic accuracy in Asians with chronic HCV.Keyur Patel Mireen Friedrich-Rust Yoav Lurie Mircea Grigorescu Carol Stanciu Chuan-Mo Lee Eugene R Schiff Dieter Hussinger Michael P Manns Guido Gerken Isabelle Colle Michael Torbenson Erik Pulkstenis G Mani Subramanian John G McHutchison Stefan Zeuzem 2011World Journal of Gastroenterology2011,17,41:4
12Hepatitis C virus infection and health-related quality of life显示文摘Hepatitis C virus(HCV) hepatitis and other diseases related to HCV,such as cryoglobulinemia,lymphoma and renal failure,impair health-related quality of life(HRQoL).In addition,HCV per se might directly influence HRQoL via colonization of microglia in the brain or,indirectly,via the effect of systemic inflammatory cytokines which,in turn,can trigger brain interleukin production.The treatment of HCV-related disorders with interferon(IFN) has an effect on HRQoL.Initially,IFN causes a transient deterioration of HRQoL,due to the induction of depression and other side effects of treatment.Subsequently,the subjects who obtain a sustained virologic response experience an improvement in HRQoL.Only rarely does interferon treatment causes permanent detrimental effects on HRQoL,due to residual psychiatric or neurologic side effects.Liver transplantation is the only treatment for end-stage HCV-related liver disease.HRQoL generally improves massively a few months after transplantation,except in the case of serious complications of the transplant procedure.Furthermore,high levels of anxiety and neuroticism pre-transplant are associated with lower HRQoL one year after transplant.Additionally,six months after transplant,patients with HCV who experience virologic recurrence show significantly greater depression,anxiety,phobic anxiety,and paranoid ideation than anti-HCV-negative patients.In conclusion,optimal care for the overall well-being of patients with HCV infection requires adequate knowledge of their neurological and psychological status.Piero Amodio Laura Salari Sara Montagnese Sami Schiff Daniele Neri Tonino Bianco Lina Minazzato 2012World Journal of Gastroenterology2012,18,19:3
