2Inflammation-associated microsatellite alterations:Mechanisms and significance in the prognosis of patients with colorectal cancer显示文摘Microsatellite alterations within genomic DNA frameshift as a result of defective DNA mismatch repair(MMR). About 15% of sporadic colorectal cancers(CRCs) manifest hypermethylation of the DNA MMR gene MLH1, resulting in mono-and di-nucleotide frameshifts to classify it as microsatellite instability-high(MSI-H) and hypermutated, and due to frameshifts at coding microsatellites generating neo-antigens, produce a robust protective immune response that can be enhanced with immune checkpoint blockade. More commonly, approximately 50% of sporadic nonMSI-H CRCs demonstrate frameshifts at di-and tetra-nucleotide microsatellites to classify it as MSIlow/elevated microsatellite alterations at selected tetranucleotide repeats(EMAST) as a result of functional somatic inactivation of the DNA MMR protein MSH3 via a nuclear-to-cytosolic displacement. The trigger for MSH3 displacement appears to be inflammation and/or oxidative stress, and unlike MSI-H CRC patients, patients with MSI-L/EMAST CRCs show poor prognosis. These inflammatory-associated microsatellite alterations are a consequence of the local tumor microenvironment, and in theory, if the microenvironment is manipulated to lower inflammation, the microsatellite alterations and MSH3 dysfunction should be corrected. Here we describe the mechanisms and significance of inflammatory-associated microsatellite alterations, and propose three areas to deeply explore the consequences and prevention of inflammation's effect upon the DNA MMR system.Minoru Koi Stephanie S Tseng-Rogenski John M Carethers 2018World Journal of Gastrointestinal Oncology2018,10,1:7

4Repeated cupping manipulation temporary decreases natural killer lymphocyte frequency, activity and cytotoxicity显示文摘OBJECTIVE: Elevated natural killer lymphocyte cytotoxicity(NKc) has been linked with reproductive problems in women. Here we evaluate the potential benefit of cupping therapy(CT) in reproductionrelated immune responses.METHODS: This was a pilot clinical study. Participants were he althy fe male volunteers(n = 23) with elevated NKc, and received repeated CT 3 times over 5 d(inner pressure 40–50 kPa, 40 min; 12–1 5 cups). Lymphocyte subsets, NKc and NK lymphocyte activity(NKa) were measured in blood on day 0(initial levels, before the first treatment) and days 3, 10 and 17 after the last CT treatment, using the K562-stimulated CD69 expression assay.RESULTS: As a result of CT manipulations NKa was reduced on days 3 and 10, and NK percentage was reduced on day 10. NKc was most sensitive to CT treatment, resulting in their decreased counts at 3, 10 and 17 d post CT. CT treatment decreased NKc in the majority of individuals(87%), but the magnitude of the effect was variable. Out of 23 subjects 9(39.1%) had a 2–3 fold decrease of NKc on days 3, 10 and 17; 11(47.8%) started to show a decrease in NKc later, or more quickly returned to base levels; and only 3(13%) subjects displayed no effect of CT on NKc. Expectedly, no changes in T-cell subsets(CD3CD4, CD3CD8, HLADR, CD158a) were observed after CT.CONCLUSION: CT decreased NK cell numbers, their activity and cytotoxicity. Low cost, safety, noninvasive nature and ease of administration make CT a promising approach for NKc down-regulation.Boris V.Dons' koi Viktor P.C hernyshov Dariia V.Osypchuk Sergiy M.Baksheev 2016Journal of Integrative Medicine2016,14,3:6

6基于图像分割的驾驶员分心行为识别研究显示文摘针对驾驶员分心行为对交通安全产生隐患的问题,提出一种结合图像分割与卷积神经网络的驾驶员分心行为检测方法。该方法通过使用图像分割处理后的驾驶员不同分心行为的图像对卷积网络结构模型进行训练,来减轻背景噪声的影响,以提高模型的识别性能。试验中使用未经分割的图像与经过前景分割后图像分别训练卷积神经网络模型,用分割后图像训练的模型识别的准确率达到了93.84%,高于使用原图像训练的模型。试验结果表明,结合图像分割和深度学习的驾驶员分心行为检测方法对驾驶员的分心行为有较好的检测效果。叶绿 陈铖 Sugianto Sugianto Chido Natasha Muponda Agordzo George Kofi Koi David Ernest 2020浙江科技学院学报2020,32,3:2
