Middle Jurassic-early Cretaceous radiolarian assemblages of the western Yarlung Zangbo Suture Zone: Implications for the evolution of the Neo-Tethys

Cherts in the Zhongba melange of the western Yarlung Zangbo Suture Zone(YZSZ)contain well preserved radiolarian assemblages. These radiolarian assemblages indicate that the Zhongba melange has middle Jurassic-early Cretaceous remnant, are coeval with those from the central and eastern parts of the YZSZ. Cherts from the Najiu area yield Aalenian to Aptian radiolarians, while cherts interbedded with siliceous mudstones from the Bielongjiala area yield Aptian radiolarians, indicating that terrigenous-derived sediments were deposited during early Aptian. The above observations indicate that the entire YZSZ have a similar geochronological framework and thus they underwent similar geological evolution:(1)during the Jurassic, the Neo-Tethys was a wide ocean with pelagic sediments distal from continents;(2)during the Cretaceous(around 130-120 Ma), the Neo-Tethys started to subduct along the southern margin of the Lhasa block, and terrigenous-derived siliceous mudstone began deposition.
猪肺异种移植的研究进展与发展方向

肺移植是治疗终末期肺疾病的唯一有效方法,但一直面临着严重的供体短缺问题。用猪肺替代人肺移植到人体内有望解决供体肺短缺的问题。但由于猪肺对多种损伤如组织灌注损伤、抗体依赖的补体损伤、适应性免疫反应以及凝血功能障碍造成的损伤等高度敏感,故而猪肺异种移植亦面临着许多难题亟待解决。本文介绍了目前异种肺移植的国内外研究现状,并归纳总结了异种肺移植的研究模型及其优缺点,着重论述了异种肺移植的损伤机制及可能的解决方案,并探讨了异种肺移植的未来发展方向。
Using Chebyshev polynomial interpolation to improve the computational efficiency of gravity models near an irregularly-shaped asteroid

In asteroid rendezvous missions, the dynamical environment near an asteroid's surface should be made clear prior to launch of the mission. However, most asteroids have irregular shapes, which lower the efficiency of calculating their gravitational field by adopting the traditional polyhedral method. In this work,we propose a method to partition the space near an asteroid adaptively along three spherical coordinates and use Chebyshev polynomial interpolation to represent the gravitational acceleration in each cell. Moreover, we compare four different interpolation schemes to obtain the best precision with identical initial parameters. An error-adaptive octree division is combined to improve the interpolation precision near the surface. As an example, we take the typical irregularly-shaped near-Earth asteroid 4179 Toutatis to demonstrate the advantage of this method; as a result, we show that the efficiency can be increased by hundreds to thousands of times with our method. Our results indicate that this method can be applicable to other irregularly-shaped asteroids and can greatly improve the evaluation efficiency.
A Critical Role of AMT2;1 in Root-To-Shoot Translocation of Ammonium in Arabidopsis

Ammonium uptake in plant roots is mediated by AMT/MEP/Rh-type ammonium transporters. Out of five AMTs being expressed in Arabidopsis roots,four AMT1-type transporters contribute to ammonium uptake, whereas no physiological function has so far been assigned to the only homolog belonging to the MEP subfamily, AMT2;1. Based on the observation that under ammonium supply,the transcript levels of AMT2;1 increased and its promoter activity shifted preferentially to the pericycle,we assessed the contribution of AMT2;1 to xylem loading. When exposed to ~(15)N-labeled ammonium,amt2;1 mutant lines translocated less tracer to the shoots and contained less ammonium in the xylem sap. Moreover, in an amt1;1 amt1;2 amt1;3amt2;1 quadruple mutant (qko), co-expression of AMT2;1 with either AMT1;2 or AMT1;3 significantly enhanced ~(15)N translocation to shoots,indicating a cooperative action between AMT2;1 and AMT1 transporters. Under N deficiency, proAMT2;1-GFP lines showed enhanced promoter activity predominantly in cortical root cells,which coincided with elevated ammonium influx conferred by AMT2;1 at millimolar substrate concentrations. Our results indicate that in addition to contributing moderately to root uptake in the low-affinity range,AMT2;1 functions mainly in root-to-shoot translocation of ammonium,depending on its cell-type-specific expression in response to the plant nutritional status and to local ammonium gradients.
Lamin-like Proteins Negatively Regulate Plant Immunity through NAC WITH TRANSMEMBRANE MOTIF1-LIKE9 and NONEXPRESSOR OF PR GENES1 in Arabidopsis thaliana

Nuclear lamins are involved in multiple biological processes in metazoan cells. The proteins of the CROWDED NUCLEI (CRWN) family are considered lamin-like candidates in Arabidopsis, although the functions of these proteins are largely unknown. In this article we show that crwn1 crwn2 double mutant displays an enhanced resistance against virulent bacterial pathogens, and both virulent bacteria and salicylic acid (SA) induce transcription of CRWN1 gene as well as proteasome-mediated degradation of CRWN1 protein. We also show that CRWN1 interacts with NAC WITH TRANSMEMBRANE MOTIF1-LIKE9 (NTL9), a NAC transcription factor involved in plant immunity. The interaction between CRWN1 and NTL9 enhances the binding of NTL9 to the promoter of the PATHOGENESIS-RELATED1 (PR1) gene, and inhibits PR1 expression. Further genetic experiments indicated that the defense-related phenotypes of crwn1 crwn2 double mutant are dependent on NONEXPRESSOR OF PR GENES1 (NPR1), a transcriptional cofactor of PR1. These findings revealed a regulatory network composed of lamin-llike protein CRWN1, NTL9, and NPR1 for the regulation of PR1 expression.
Bayesian seismic multi-scale inversion in complex Laplace mixed domains

Seismic inversion performed in the time or frequency domain cannot always recover the long-wavelength background of subsurface parameters due to the lack of low-frequency seismic records. Since the low-frequency response becomes much richer in the Laplace mixed domains, one novel Bayesian impedance inversion approach in the complex Laplace mixed domains is established in this study to solve the model dependency problem. The derivation of a Laplace mixed-domain formula of the Robinson convolution is the first step in our work. With this formula, the Laplace seismic spectrum, the wavelet spectrum and time-domain reflectivity are joined together. Next, to improve inversion stability, the object inversion function accompanied by the initial constraint of the linear increment model is launched under a Bayesian framework. The likelihood function and prior probability distribution can be combined together by Bayesian formula to calculate the posterior probability distribution of subsurface parameters. By achieving the optimal solution corresponding to maximum posterior probability distribution, the low-frequency background of subsurface parameters can be obtained successfully. Then, with the regularization constraint of estimated low frequency in the Laplace mixed domains, multi-scale Bayesian inversion in the pure frequency domain is exploited to obtain the absolute model parameters. The effectiveness, anti-noise capability and lateral continuity of Laplace mixed-domain inversion are illustrated by synthetic tests. Furthermore, one field case in the east of China is discussed carefully with different input frequency components and different inversion algorithms. This provides adequate proof to illustrate the reliability improvement in low-frequency estimation and resolution enhancement of subsurface parameters, in comparison with conventional Bayesian inversion in the frequency domain.
Proactive control of cresting in homogeneous oil reservoirs: an experimental study

This paper sets out to investigate experimentally the use of electromagnetic valves in controlling production of water during cresting from homogeneous non-fractured thick-oil and thin-oil reservoirs, based on the principle of capillarity and breakthrough time. A time half the initial breakthrough times was preset for the electromagnetic valve to close. The valve closed almost immediately at the set time thereby shutting oil production temporarily, causing the water and gas height levels to recede by gravity and capillarity with receding reservoir pressure. The efficiency of this technique was compared with an uncontrolled simulation case, in terms of cumulative oil, oil recovery and water produced at the same overall production time. From the results obtained, higher percentages in oil produced and water reduction were observed in the cases controlled proactively, with a 3.6% increase in oil produced and water reduction of 10.0% for thick-oil rim reservoirs, whereas only a small increment in oil produced (0.7%) and a lower water reduction of 1.03% were observed for the thin-oil rim reservoirs. Hence, the effectiveness of the cresting control procedure depends on the oil column height of the reservoir.
Gas sorption and non-Darcy flow in shale reservoirs

Gas sorption and non-Darcy flow are two important issues for shale gas reservoirs. The sorption consists of dissolution and adsorption. Dissolved gas and adsorbed gas are different. The former is dissolved in the shale matrix, while the latter is concentrated near the solid walls of pores. In this paper, the Langmuir equation is used to describe adsorption and Henry's law is used to describe dissolution. The K coefficient in Henry's law of 0.052 mmol/(MPa g TOC) is obtained by matching experimental data. The amount of dissolved gas increases linearly when pressure increases. Using only the Langmuir equation without considering dissolution can lead to a significant underestimation of the amount of sorbed gas in shales. For non-Darcy gas flow, the apparent permeability model for free gas is established by combining slip flow and Knudsen flow. For adsorbed gas, the surface diffusion effect is also considered in this model. The surface diffusion coefficient is suggested to be of the same scale as the gas self-diffusion coefficient, and the corresponding effective permeability is derived. When 1/p increases,(k_(app)/_(k_D) increases, but the relationship is not linear as the Klinkenberg effect suggests. The effect of adsorption on the gas flow is significant in nanopores (r < 2 nm). Adsorption increases apparent permeability in shales at low pressures and decreases it at high pressures.
Self-Protection against Triptolide-Induced Toxicity in Human Hepatic Cells via Nrf2-ARE-NQO1 Pathway

Objective: To find the signaling pathway of triptolide (TP)-induced liver injury and to revealwhether NF-E2-related factor 2 (Nrf2) plays an important role in cellular self-protection. Methods: The L-02 andHepG2 cells were cultured and treated with various concentrations of TP. The cell viability was observed, andthe cell medium was collected for detecting the aspartate aminotransferase (ALT), alanine aminotransferase(AST), lactate dehydrogenase (LDH), superoxide dismutase (SOD) and L-glutathione production (GSH) levels.Nrf2 and its downstream target NAD(P)H: quinine oxidoreductase 1 (NQO1) and heme oxygenase-1 (HO-1)expression, the nuclear translocation of Nrf2, and the binding ability of Nrf2 and antioxidant response element(ARE) were also identified. Meanwhile,shRNA was used to silence Nrf2 in L-02 cells to find out whether Nrf2plays a protective role. Results: The viability of the L-02 and HepG2 cells treated with TP decreased in a doseandtime-dependent manner, and TP (20–80 μg/mL) markedly induced the release of ALT, AST and LDH(P<0.05 or P<0.01), reduced the levels of SOD and GSH (P<0.01), and increased the intracellular reactiveoxygen species. Meanwhile, TP augmented the Nrf2 expression in L-02 and HepG2 cells (P<0.05 or P<0.01),induced Nrf2 nuclear translocation, increased the Nrf2 ARE binding activity, and increased HO-1 and NQO1expressions. Nrf2 knockdown revealed a more severe toxic effect of TP (P<0.05 or P<0.01). Conclusions: Humanhepatic cells treated with TP induced oxidative stress, and led to cytotoxicity. Self-protection against TP-inducedtoxicity in human hepatic cells might be via Nrf2-ARE-NQO1 transcriptional pathway.

A case of Galen vein thrombosis occurring after bilateral acetabular fractures in the Tibet plateau e what can we learn?

Hypoxia leads to increased red blood cells and blood viscosity at high altitude while moderate trauma increases coagulation in blood. Under the above-mentioned conditions, venous sinus thrombosis is more likely to occur. A patient suffering bilateral acetabular fractures together with the gradual disturbance of consciousness was admitted to our hospital. Though computed tomography arteriogram (CTA) of the brain displayed normal blood vessels; bilateral thalamus and brainstem infarction were found on head computed tomography (CT) and Galen vein thrombosis on cerebral computed tomography venography (CTV). Dehydration and tracheotomy were immediately conducted with antiplatelet, anticoagulant and neurotrophic medicine administered to the patient. After three days' treatment, the patient's consciousness gradually improved and eventually became clear enough to leave the hospital. On follow-up, no dysfunction was documented.
焦虑障碍认知重评异常的脑机制研究进展

焦虑障碍是一组以病理性焦虑为主要临床表现的精神障碍,年患病率达18%,严重影响患者社会功能和生活质量,其发病机制尚不清楚。关于焦虑的临床模型研究显示,个体对内外环境刺激持续负性评价,导致情绪调节能力缺陷,是产生病理性焦虑的重要环节近年来关于情绪理论与试验研究有了较大进展,研究者们应用新的理论与技术对焦虑障碍个体的情绪调节(emotion regulation),尤其是认知重评(cognitive reappraisal)的神经机制开展了深入探讨。我们对上述问题进行综述,旨在为阐明焦虑障碍心理生理机制提供新的思路。DSM-Ⅳ中焦虑障碍包含广泛性焦虑障碍、惊恐障碍、社交焦虑障碍、创伤后应激障碍、强迫障碍等亚型,而DSM-5中则不再将创伤后应激障碍和强迫障碍归类于焦虑障碍。由于本文检索到的文献入组标准均为DSM-Ⅳ标准,并且持续的病理性焦虑也是创伤后应激障碍和强迫障碍的重要表现,故我们按照DSM-Ⅳ体系阐述。
ICD-11精神与行为障碍(草案)关于分离性障碍诊断标准的进展

分离性障碍以记忆、思维、身份、情感、感觉、知觉等成分正常整合过程中出现非自主扰乱或中断为特征。国内精神科就诊人群中,分离性障碍所占比例高于一般人群,危害性大。国内1项大型流行病学研究应用分离体验量表评估了423例住院患者、304例门诊患者和618名工厂工人,结果显示在门诊患者中可识别出病理性分离障碍患者,但在一般性人群中相对罕见,而病理性分离在创伤人群中更为常见。Yu等的研究显示精神分裂症与分离性障碍存在较高的共病率,验证了以上结论。
Enhanced Antibacterial Activities of La/Zn-doped BiNbO_4 Nanocomposites

Bi_(1-x)La_xNbO_4 and Bi_(1-x)Zn_xNbO_4 nanocomposites were prepared by a simple coprecipitation method, and their composition, structure and morphology were characterized by modern testing techniques. The antibacterial activities of the as-prepared samples against Staphylococcus aureus, Escherichia coli and Candida albicans were measured by the experiments of powder inhibition zone, inhibition zone diameter and minimum inhibitory concentration under the irradiation of sunlight. The results show that the antibacterial activities of BiNbO_4 doped with La and Zn are superior to that of the parent, and the composition of antibacterial agent and their mass ratio have a great influence on the antibacterial activities. Among these, the antibacterial activity of Bi_(0.96)La_(0.04)NbO_4 against three bacteria was best and its antibacterial activity to Candida albicans was better than those to the other two kinds.
Structure and Enhanced Antifungal Activity of a Divalent Cobalt(II) Complex with Hexaconazole

A new Co~(II) complex, [CoL_4Cl_2]·2CH_3CH_2OH(L=hexaconazole), was synthesized and characterized by means of elemental analysis, infrared spectroscopy and single-crystal X-ray diffraction. The crystal structural analysis shows that the centrosymmetric Co~(2+) is coordinated by four hexaconazole ligands and two Cl~- to form a distorted octahedral geometry. The complex forms 1D chains through the intermolecular hydrogen bonds interaction of O—H…O and O-H…Cl. Furthermore, the antifungal activities of the complex against Grape anthracnose(I), Bo-tryosphaeria berengriana(II), Botryosphaeria ribis(III) and Wheat gibberellic(IV) have been investigated and compared with those of the corresponding ligand. The results show that the complex has better antifungal activity than the ligand, which indicates that the coordination of the ligand and the metal enhances the antimicrobialactivity.
Flexible carbon nanotube-enriched silver electrode films with high electrical conductivity and reliability prepared by facile screen printing

Flexible electrode films play critical and fundamental roles in the successful development of flexible electronic devices. In this study, carbon nanotubes (CNTs) were implanted into silver (Ag) ink to enhance the electrical conductivity and the reliability of the printed Ag electrode films. The fabricated carbon nanotubes-enriched silver (Ag-CNTs) electrode films were printed on the polyimide substrates by a facile screen printing method and sintered at a relatively low temperature. The resistivity of Ag-CNTs films was decreased by 62.27% compared with the pure Ag film. Additionally, the Ag-CNTs films exhibited excellent flexibility under a bending radius of 4mm(strain ε = 2.09%) over 1000 cycles. Furthermore, the Ag-CNTs film displayed unchangeable electrical conductivity together with a strong adhesion after an accelerated aging test with 500 thermal shock cycles. These improvements were attributed to the Ag-CNTs interconnected network structure, which can provide electronic transmission channels and prevent cracks from initiating and propagating.
Experimental charge density distribution and its correlation to structural and optical properties of Sm~(3+) doped Nd_2O_3 nanophosphors

Pure and Sm~(3+) doped Nd_2O_3 nanophosphors were synthesized using modified Pechini method. The phase formation with symmetry of the sample is confirmed by the Rietveld refinement of the powder Xray diffraction (PXRD) data. The surface morphology and the crystallite size were examined using scanning electron microscopy (SEM) and transmission electron microscopy (TEM) and the results confirmed that the synthesized particles are in nanosize. The energy-dispersive X-ray (EDX) analysis was done to confirm the purity of the sample. The optical properties of the sample were studied using ultravioletevisible range (UVeVis) spectroscopic analysis and photoluminescence studies. The calculated band gap of the synthesized Nd_2O_3 was found to be higher than that of bulk Nd_2O_3. The photoluminescence (PL) of the prepared samples reveals that doping with Sm~(3+) ion has influenced the optical properties. Quantitative investigation on charge density distribution was done by analysing the 3-dimensional and 2-dimensional charge density maps drawn along the bonding directions. The maximum entropy method (MEM)/Rietveld analysis was used for the first time to analyse the charge density in the chosen system. Charge density arrangement in the unit cell is correlated to the analysed photoluminescent (PL) properties. The spectral behaviour of the samples has been explained through charge ordering which are verified using experimental data obtained. The studies on these materials have shown that these nanophosphors will provide promising application for near-ultraviolet lightemitting diodes (n-UV-LEDs).
矽肺药物治疗的进展

矽肺是我国最常见的职业病之一,是尘肺中最主要的一种类型,吸入二氧化硅(SiO_2)粉尘是主要致病因素。SiO_2所致的肺损伤主要包括肺泡上皮细胞损伤和其他细胞释放出各种细胞因子、炎症介质、蛋白酶、活化氧(ROS)和活化氮(RNS)。这些因子促进炎症细胞在局部聚集,结果导致异常纤维增生和胶原沉积。矽肺的病理过程包括肺的慢性炎症反应和纤维化,肺纤维化加剧肺功能损伤。在国家卫计委公布的《2014年全国职业病报告》显示,我国矽肺的发病率持续增长,2014年有26873例新增尘肺病例,其中11471(42.69%)是矽肺。尽管矽肺的患病率不低,和其他呼吸系统疾病相比,矽肺药物治疗的发展远不如其他疾病。我们综述了国内矽肺药物治疗的现状和进展,为将来矽肺的治疗提供的新的可能方向。

Late Quaternary Activity of the Chuxiong-Nanhua Fault and the 1680 Chuxiong M_S63/4 Earthquake

In this paper,according to the results of the satellite imagery interpretation and field investigation,we study the active features and the latest active times of the Chuxiong- Nanhua fault,the Quaternary basins formation mechanism,and the relationship between the fault and the 1680 Chuxiong M_S63/4 earthquake. Several Quaternary profiles at Lvhe, Nanhua reveal that the fault has offset the late Pleistocene deposits of the T2 and T3 terraces of Longchuan river, indicating that the fault was obviously active in late Quaternary. The Chuxiong-Nanhua fault has been dominated by dextral strike slip motion in the late Quaternary,with an average rate of 1. 6 - 2. 0mm/a. Several pull apart Quaternary basins of Chuxiong,Nanhua,and Ziwu etc. have developed along the fault. The 1680 Chuxiong M_S63/4 earthquake and several moderate earthquakes have occurred near the fault. The Chuxiong-Nanhua fault are the seismogenic structure of those earthquakes,the latest fault movement was in the late-Pleistocene,and even the Holocene. In large area,the Chuxiong-Nanhua fault and the eastern Qujiang fault and the Shiping fault composed a set of NW-trending oblique orientation active faults,and the motion characteristics are all mainly dextral strike slip. The motion characteristics,like the red river fault of the Sichuan-Yunnan Rhombic Block southwestern boundary,are concerned with the escaping movement of the Sichuan-Yunnan Rhombic Block.
Shaking Table Test Study on Dynamic Characteristics of Bridge Foundation Reinforcement on Slopes

With the fast development of bridge construction in mountainous and seismic areas,it is necessary to conduct related research. Based on the design of a shaking table model test, here are the following test results: the filtering effect exists in soil and is affected by the dynamic constraint conditions,the amplitude is strengthened around the natural frequency and weakened in other frequency bands in the Fourier spectrum. Since the acceleration scaling effect occurred on a sloped surface,the acceleration response decreases from the outside to the inside in soil. The dynamic response is relatively strong near the slip surface in bedrock due to the reflection of seismic waves. The failure mode of landslide is decided by the slope angle and slipping mass distribution,and the test shows the front row stabilizing piles should keep a proper distance from bridge foundation so that seismic resistance can be guaranteed for the bridge foundation.
