There are many factors affecting the chemical characteristics of groundwater in the forming process of groundwater chemical fields, such as freshening due to meteoric water leaching downwards, freshening due to mudstone compaction and water release, concentration due to infiltration and freshening due to dehydration of clay minerals. As a result, the groundwater chemical fields are characterized by lengthwise stages and planar selectivity. The former arouses vertical chemical zonality of groundwater. Five units could be identified downwards in the Songliao basin：（1） freshening zone due to downward-leaching meteoric water, （2） concentration zone due to evaporation near the ground surface, （3） freshening zone due to mudstone compaction and water release, and concentration zone due to compaction and infiltration, （4） freshening zone due to dehydration of clay minerals, and （5） filtration-concentration zone; whereas the latter determines the planar division of groundwater chemical fields：（1） the freshening area due to meteoric water, asymmetrically on the margin of the basin, （2） the freshening area due to mudstone compaction and water release in the central part of the basin, （3） the leaky area, which is a transitional zone, and （4） leakage-evaporation area, which is a concentration zone. In the direction of centrifugal flows caused by mudstone compaction in the depression area, the mineralization degree, concentrations of Na^＋ and Cl^-, and salinity coefficient （SC） increase, while concentrations of （CO3^2- ＋HCO3^-） and SO4^2-, metamorphism coefficient （MC） and desulfuration coefficient （DSC） decrease. However, all these parameters increase in the direction of gravity-induced centripetal flows.

TCAB1(Telomere Cajal Body protein 1) is an important component of Cajal body. It participates in telomere elongation, repairs DNA double strands break and promotes tumor development. Its high expression is related to cell proliferation and poor prognosis of patients. However, little is known about the mechanism through which it regulates cancer progression. Our team found that overexpression of TCAB1 can promote the proliferation and migration of A549 cells. Conversely, downregulation of TCAB1 inhibited cell proliferation and migration of A549 cells. GST-Pulldown and Co-IP experiments showed that TCAB1 interacted with USP11 in cells. USP11(Ubiquitin-specific peptidase11)is a deubiquitinase, which can activate the TGFβ pathway and promote EMT by stabilizing TGFβRⅡ. Moreover, we found that overexpression of TCAB1 increased the protein level of intracellular TGFβRⅡ. Our research group will further examine the effect of TCAB1 on the activity of USP11 deubiquitinase through in vitro deubiquitination experiments, and detect the mechanism of TCAB1 on EMT. Our study provides evidence that TCAB1 promotes tumor migration by activating TGFβ pathway and suggests that downregulating TCAB1 may be a promising therapeutic approach for cancer treatment.

Multimodal 3D Convolutional Neural Networks for Classification of Brain Disease Using Structural MR and FDG-PET Images

引用

国际计算机前沿大会会议论文集 2019年第1期 666-668页

作者： Kun Han Haiwei Pan ruiqi gao Jieyao Yu Bin Yang Harbin Engineering University Harbin People’s Republic of China

The classification and identification of brain diseases with multimodal information have attracted increasing attention in the domain of computer-aided. Compared with traditional method which use single modal feature information, multiple modal information fusion can classify and diagnose brain diseases more comprehensively and accurately in patient subjects. Existing multimodal methods require manual extraction of features or additional personal information, which consumes a lot of manual work. Furthermore, the difference between different modal images along with different manual feature extraction make it difficult for models to learn the optimal solution. In this paper, we propose a multimodal 3D convolutional neural networks framework for classification of brain disease diagnosis using MR images data and PET images data of subjects. We demonstrate the performance of the proposed approach for classification of Alzheimer’s disease (AD) versus mild cognitive impairment (MCI) and normal controls (NC) on the Alzheimer’s Disease National Initiative (ADNI) data set of 3D structural MRI brain scans and FDG-PET images. Experimental results show that the performance of the proposed method for AD vs. NC, MCI vs. NC are 93.55% and 78.92% accuracy respectively. And the accuracy of the results of AD, MCI and NC 3-classification experiments is 68.86%.

目的:分析术前糖化血红蛋白(HbA1c)水平对糖尿病患者白内障超声乳化术后后囊膜混浊(PCO)的预测价值及阈值效应。方法:回顾性研究。收集2018-09/2020-09于本院就诊的糖尿病合并白内障患者106例106眼,根据患者术后36 mo是否发生PCO分为PCO组52例52眼和非PCO组54例54眼。分析患者术后发生PCO的影响因素。对患者术前HbA1c水平与患者术后发生PCO的发生情况进行阈值效应分析。采用受试工作者特征(ROC)曲线评估术前HbA1c水平对患者术后发生PCO的预测价值。构建预测模型,采用Bootstrap重采样对预测模型进行验证,并对模型的区分度和准确度进行评价。结果:两组患者糖尿病病程、有无糖尿病视网膜病变、空腹血糖、餐后2 h血糖、术前HbA1c、眼轴长度、核硬度分级均有差异(P<0.05)。糖尿病病程≥12 a、有DR、空腹血糖≥8 mmol/L、餐后2 h血糖≥12 mmol/L、术前HbA1c≥7%、眼轴长度≥30 mm、核硬度分级Ⅲ级及以上均为影响患者术后发生PCO的因素(P<0.05)。曲线拟合发现随着HbA1c水平的升高,糖尿病患者白内障超声乳化术后发生PCO的概率呈现上升趋势。阈值效应分析发现,当HbA1c≥7%时,术后PCO的发生率随着HbA1c水平的增加而升高。敏感性分析显示E值=2.129。术前HbA1c与糖尿病患者白内障超声乳化术后发生PCO程度的关联效应分析结果显示,调整后术前HbA1c水平是糖尿病患者术后发生PCO不同程度混浊的影响因素,存在独立相关性(OR=1.65,95%CI:1.42-1.76,P=0.021)。当预测模型P=0.6时,模型预测准确度为88.51%,敏感度和特异度分别为86.33%和86.82%,表示糖尿病白内障患者出现PCO的结局。结论:糖尿病病程、有DR、空腹血糖、餐后2 h血糖、术前HbA1c、眼轴长度、核硬度分级是影响糖尿病患者白内障超声乳化术后发生PCO的因素,且术前HbA1c可作为评估患者术后发生PCO的敏感指标。

针对高维数据聚类分析中数据之间具有多种非线性特征关系,导致数据分布不均、传统相似性度量失效及结果类中心难以精准表征等问题,提出了一种基于核主元分析(KPCA)与密度聚类(DBSCAN)的高维非线性特征数据聚类分析技术。首先,为有效提取高维数据的非线性特征,利用KPCA理论将原始数据映射到更高维数据空间,利用主元分析获得数据变化的方向集合,并进行降维分析;然后,通过重新定义数据样本在主元空间的相似性距离对传统DBSCAN聚类方法进行改进,并利用3δ统计理论对各簇中心的进行表征,从而实现高维数据的精确分类与类中心知识表达。以实际高血压患者群体聚类问题为例对方法进行了有效性验证,实验表明,所提方法可以有效获取原始数据的非线性特征,实现患者个体特征群体的有效划分及簇类中心知识的表达,解决传统DBSCAN聚类方法对高维数据不适用的问题。
