川东北元坝西部须二段—须三段是重要的油气产层。本文利用钻井岩心、测井资料和三维地震资料对川东北元坝西部上三叠统须二段—须三段沉积相类型、沉积特征、沉积模式及其对储层发育控制作用开展详细的研究,以指导该地区的油气勘探部署。结果表明,川东北元坝西部须二段—须三段主要为辫状河三角洲相和湖泊相沉积,能够识别出三角洲平原、三角洲前缘、前三角洲和浅湖4种亚相,可进一步划分出9种微相。须二段—须三段沉积时期发育两种沉积模式,须二段为缓坡型宽河道辫状河三角洲沉积模式,主要发育宽河道,砂体叠置连片;须三段为陡坡型窄河道辫状河三角洲沉积模式,主要发育窄河道,砂体沿河道呈条带状分布。须二段主要发育中粒长石岩屑砂岩和中粒石英砂岩两种有利储集岩类型,主要分布于三角洲前缘水下分流河道砂体中;须三段发育中粗粒钙屑砂岩和砂质细砾岩两种有利储集岩类型,主要分布于三角洲平原辫状河道—三角洲前缘水下分流河道过渡带砂体中。缓坡型宽河道辫状河三角洲中发育的中粒长石岩屑砂岩和中粒石英砂岩储层物性和孔隙结构明显好于陡坡型窄河道辫状河三角洲中发育的中粗粒钙屑砂岩和砂质细砾岩。

目的:对比分析纳米复合树脂和光固化复合树脂材料用于前牙美容修复中的应用价值及对修复效果、咀嚼功能的影响。方法:选取2020年2月-2022年2月于笔者医院接受前牙美容修复治疗的80例患者(共186颗患牙)为研究对象,根据随机数字表法将入组患者分为观察组和对照组,各40例。对照组给予光固化复合树脂修复,观察组给予纳米复合树脂材料修复,观察两组前牙修复的优良率,对比治疗前后牙周指标及咀嚼功能的变化。结果:治疗后,观察组前牙修复总优良率明显高于对照组(P<0.05);治疗后两组牙龈指数、龈沟出血指数、菌斑指数、牙松动程度、咬合力、咀嚼效率均得到较大改善(P<0.05),且观察组改善程度均优于对照组(P<0.05)。结论:纳米复合树脂和光固化复合树脂材料在前牙美容修复中均可发挥较好的临床效果,但前者优势更大,修复效果较光固化树脂更佳,不仅能改善牙龈健康状况,还能促进咀嚼功能提升,对于术后尽快恢复也具有积极意义。

Hypoxia acts as an important regulator of physiological and pathological processes. Hypoxia inducible factors(HIFs) are the central players involved in the cellular adaptation to hypoxia and are regulated by oxygen sensing EGLN prolyl *** affects many aspects of cellular growth through both redox effects and through the stabilization of HIFs. The HIF isoforms likely have differential effects on tumor growth via alteration of metabolism, growth, and self-renewal and are likely highly context-dependent. In some tumors such as renal cell carcinoma, the EGLN/HIF axis appears to drive tumorigenesis,while in many others HIF1 and HIF2 may actually have a tumor suppressive role. An emerging role of HIF biology is its effects on the tumor microenvironment. The EGLN/HIF axis plays a key role in regulating the function of the various components of the tumor microenvironment, which include cancer-associated fibroblasts, endothelial cells, immune cells, and the extracellular matrix(ECM). Here, we discuss hypoxia and the diverse roles of HIFs in the setting of tumorigenesis and the maintenance of the tumor microenvironment as well as possible future directions of the field.

高光谱遥感图像分类已被公认为是高光谱数据处理的基础性和挑战性任务之一,其最终目标是给影像中的每个像元赋予唯一的类别标识。针对传统高光谱遥感图像分类方法只依靠单一特征进行分类的问题,提出一种基于空谱多特征融合的分类策略。首先在光谱域上利用主成分分析法PCA降维,得到前3个主成分数据,然后通过多视图策略对PCA降维后的数据分别提取局部二值模式LBP、方向梯度直方图HOG与Gabor特征,将其输入到多视图支持向量机进行分类。所提方法在Indian Pines数据集上进行验证,实验结果表明,所采用的分类策略相较于传统只利用单一特征进行分类的方法分类精度更高。

Morganella morganii strain 602-1 was isolated from a sick Chinese giant salamander （Andrias davidianus）. The strain 602-1 was identified through its physiological and biochemical properties and 16S rDNA gene amplification and analyses. Pathogenicity was proven by experimental animal infection, and histopathological examination. The results showed that the amplified 16S rDNA sequence of strain 602-1 was 1455 bp, and showed 99% identity with M. morganii. In the host infection experiment, the mortality of Chinese giant salamanders was about 70%. Pathological changes occurred in the spleen, heart, liver, kidney and intestine. This study will help the prevention, understanding and cure for M. morganii infections in amphibians.
