慢性疼痛患者重要他人疼痛回应的研究进展

慢性疼痛是指超过3个月及以上的持续或间歇性疼痛[1],常给患者身心健康和生活质量带来较大困扰。2020年国际疼痛学会(The International Association for the Study of Pain,IASP)重新修订了疼痛定义,强调疼痛是一种生理、心理和社会因素交互影响的个人主观体验[2]。作为影响疼痛的社会因素之一,重要他人这一概念近年来逐渐开始受到国外学者的关注。重要他人是指与个体有重要关系的具体人物,是个体社会网络的重要组成部分[3]。研究[4-5]显示,重要他人对慢性疼痛患者的疼痛回应与患者疼痛程度、疼痛行为、抑郁及躯体功能均密切相关,但国内尚未见此类研究的报道。因此,本文对重要他人疼痛回应的概念、评估工具、对慢性疼痛患者的影响和干预策略进行综述,以期为今后开展相关研究提供参考。
Ultraviolet humic-like component contributes to r iver ine dissolved organic matter biodegradation

Biological degradation of dissolved organic matter (DOM) regulates its structure and fate in river ecosystems. Previous views suggested that labile components were dominantly consumed by microbial metabolism. Here we provide new observations that a part of recalcitrant compounds largely contribute to riverine DOM biodegradation. The excitationemission matrix fluorescent spectroscopy combined with peak picking and parallel factor analysis are used to explore component variability during DOM incubation. Humic-like and tryptophan-like DOM are the primary components of riverine DOM, with proportion contributions of 39%-82% and 16%-61% for % of the maximum fluorescence intensity, respectively. After 56 days of aerobic incubation in the dark, large amounts of tyrosine-like DOM generation are observed. Elevated temperature enhances the decomposition of ultraviolet humiclike substance and further stimulates labile DOM bio-mineralization into carbon dioxide. Meanwhile, averaged proportions of amino acid compositions (peak B and T) markedly increase ( p < 0.05) as the humic-like compositions (peak A, M and C) decrease after DOM incubation, suggesting incomplete degradation of refractory DOM from high-molecular to low-molecular weight compounds. The findings support the new notion of the continuous DOM biodegradation in a mode as “steps by steps”, contributing to a new understanding of carbon cycling for the UN Sustainable Development Goal.
Repeated hydrogen peroxide dosing briefly reduces cyanobacterial blooms and microcystin while increasing fecal bacteria indicators in a eutrophic pond

This study explored the effects of H_2O_2 on Cyanobacteria and non-target microbes using fluorometry, microscopy, flow cytometry, and high throughput DNA sequencing of the 16S rRNA gene during a series of mesocosm and whole-ecosystem experiments in a eutrophic pond in NY, USA. The addition of H_2O_2 (8 mg/L) significantly reduced Cyanobacteria concentrations during a majority of experiments (66%; 6 of 9) and significantly increased eukaryotic green and unicellular brown algae in 78% and 45% of experiments, respectively. While heterotrophic bacteria declined significantly following H_2O_2 addition in all experiments, bacteria indicative of potential fecal contamination ( Escherichia coli, Enterococcus, fecal coliform bacteria) consistently and significantly increased in response to H_2O_2, evidencing a form of ‘pollution swapping'. H_2O_2 more effectively reduced Cyanobacteria in enclosed mesocosms compared to whole-ecosystem applications. Ten whole-pond H_2O_2 applications over a twoyear period temporarily reduced cyanobacterial levels but never reduced concentrations below bloom thresholds and populations always rebounded in two weeks or less. The bacterial phyla of Cyanobacteria, Actinobacteria, and Planctomycetes were the most negatively impacted by H_2O_2. Microcystis was always reduced by H_2O_2, as was the toxin microcystin, but Microcystis remained dominant even after repeated H_2O_2 treatments. Although H_2O_2 favored the growth of eukaryotic algae over potentially harmful Cyanobacteria, the inability of H_2O_2 to end cyanobacterial blooms in this eutrophic waterbody suggests it is a non-ideal mitigation approach in high biomass ecosystems and should be used judiciously due to potential negative impacts on non-target organisms and promotion of bacteria indicative of fecal contamination.
0D/3D direct Z-scheme heterojunctions hybridizing by MoS_2 quantum dots and honeycomb conjugated triazine polymers (CTPs) for enhanced photocatalytic performance

Herein, a novel direct Z-scheme photocatalyst was accomplished by hybridization of 0D MoS_2 quantum dots (MSQDs) and 3D honeycomb-like conjugated triazine polymers (CTP) (namely, CTP-MSQD). The unique 0D/3D hierarchical structure significantly enhanced the exposure of active sites and light harvesting property, while the formed p-n junction enabled the direct strong interface coupling without the necessity of any mediators. The optimized CTP-MSQD3 exhibited continuously increased visible-light-driven photocatalytic activity and strong durability both in Cr(VI) reduction and H_2 evolution, featured a rate of 0.069 min~(-1) and 1070 μmol/(hr·g), respectively, which were 8 times than those of pure 3D-CTP (0.009 min~(-1) and 129 μmol/(hr·g)). We believe that this work provides a promising photocatalyst system that combines a 0D/3D hierarchical structure and a Z-scheme charge flow for efficient and stable photocatalytic conversion.
Effects of persulfate-assisted hydrothermal treatment of municipal sludge on aqueous phase characteristics and phytotoxicity

Hydrothermal technology (HT) has received much attention in recent years as a process to convert wet organic waste into hydrochar.The aqueous phase (HTAP) produced by this process is still a burden and has become a bottleneck issue for HT process development.In this study,we provide the first investigation of the HTAP characteristics,phytotoxicity,and their correlation with persulfate (PS) (PS,2.0 mmol/g TS)-assisted municipal sludge HT.The results showed that PS accelerated the hydrolysis of protein substances and increased the concentration of NH_4~+ by 13.4% to 190.5% and that of PO_4~(3-) by 24.2% to 1103.7% in HTAP at hydrothermal temperatures of 120 to 240 °C.PS can reduce the phytotoxicity of HTAP by reducing aldehydes,ketones,N heterocyclic compounds,and particle size and by increasing its humification index.The maximum values of the root length and biomass of pakchoi (Brassica chinensis L.) seedlings occurred when electrical conductivity was 0.2 mS/cm of HTAP.This work provided a new strategy for the selection and design of HTAP management strategies.
Effect of La~(3+) substitution on structural, microstructure, magnetic properties, and microwave absorbing ability of yttrium iron garnet

Synthesis and characterization of lanthanum-doped yttrium iron garnet (YIG) in the compositional series of Y_3exLa_xFe_5O_(12) (x = 0.0, 0.1, 0.3, and 0.5) were carried out. All compositions were made by using solid state reaction method with ball-milling technique. The phase formation, surface morphology, magnetic properties, and microwave absorbing ability of all compositions were characterized by using an X-ray diffractometer, a scanning electron microscope, a vibrating sample magnetometer, and a Vector network analyzer. The results reveal that all compositions are crystallized into Y_3Fe_5O_(12) phase (space group Ia-3d (230). It was observed that the lattice constant is increased from 1.2373 to 1.2421 nmwith the increase of lanthanum substitution level from x = 0.0 - 0.5. The crystallite size of Y_(3-x)La_xFe_5O_(12) series calculated by Scherrer method is found to decrease from 78 nm in x = 0.0-63 nm in x = 0.5. The particle size distribution from the surface morphology image analysis is shifted to lower-range number with the increase of lanthanum substitution level from x = 0.0 to 0.5. The substitution process also affects the lattice distortion in La-doped samples and changes the bond angles and bond lengths of the YIG structure. As the results, a linear correlation between the Fe'eOeFe bond angle with magnetic properties parameters of saturation magnetization (Ms) and remanence magnetization (Mr) was studied. Due to the lanthanum substitution process, all La~(3+)-doped samples possess higher Ms and Mr values compared to the original composition. The results of Vector network analyzer show that the improvement of the Ms and Mr plays an important role in enhancing the microwave absorbing ability of the materials. The minimum RL changes from -8.22 dB (~ 85.22% microwave absorption) in x = 0.0 to -14.21 dB (~96.25% microwave absorption) in x = 0.5. The enhancement is mainly ascribed to the natural magnetic resonance loss and dipole-polarization loss due to the substitution process. The decreasing particle size also enhances the microwave absorbing ability of the La-doped samples via multiple-reflections mechanism.
A review of addressing class noise problems of remote sensing classification

The development of image classification is one of the most important research topics in remote sensing. The prediction accuracy depends not only on the appropriate choice of the machine learning method but also on the quality of the training datasets. However, real-world data is not perfect and often suffers from noise. This paper gives an overview of noise filtering methods. Firstly, the types of noise and the consequences of class noise on machine learning are presented. Secondly, class noise handling methods at both the data level and the algorithm level are introduced. Then ensemble-based class noise handling methods including class noise removal, correction, and noise robust ensemble learners are presented. Finally, a summary of existing data-cleaning techniques is given.
Low copy numbers for mitochondrial DNA moderates the strength of nuclear-cytoplasmic incompatibility in plants

Plant cells contain only small amounts of mitochondrial DNA (mtDNA), with the genomic information shared among multiple mitochondria. The biological relevance and molecular mechanism underlying this hallmark of plant cells has been unclear. Here, we report that Arabidopsis thaliana plants exhibited significantly reduced growth and mitochondrial dysfunction when the mtDNA copy number was increased to the degree that each mitochondrion possessed DNA. The amounts of mitochondrion-encoded transcripts increased several fold in the presence of elevated mtDNA levels. However, the efficiency of RNA editing decreased with this excess of mitochondrion-encoded transcripts, resulting in impaired assembly of mitochondrial complexes containing mtDNA-encoded subunits, such as respiratory complexes I and IV. These observations indicate the occurrence of nuclear- mitochondrial incompatibility in the cells with increased amounts of mtDNA and provide an initial answer to the fundamental question of why plant cells have much lower mtDNA levels than animal cells. We propose that keeping mtDNA levels low moderates nuclear- mitochondrial incompatibility and that this may be a crucial factor driving plant cells to restrict the copy numbers of mtDNA.
5G Ultra-Dense Network Fingerprint Positioning Method Based on Matrix Completion

The problem of high-precision indoor positioning in the 5G era has attracted more and more attention. A fingerprint location method based on matrix completion (MC-FPL) is proposed for 5G ultradense networks to overcome the high costs of traditional fingerprint database construction and matching algorithms. First, a partial fingerprint database constructed and the accelerated proximal gradient algorithm is used to fill the partial fingerprint database to construct a full fingerprint database. Second, a fingerprint database division method based on the strongest received signal strength indicator is proposed, which divides the original fingerprint database into several sub-fingerprint databases. Finally, a classification weighted K-nearest neighbor fingerprint matching algorithm is proposed. The estimated coordinates of the point to be located can be obtained by fingerprint matching in a sub-fingerprint database. The simulation results show that the MC-FPL algorithm can reduce the complexity of database construction and fingerprint matching and has higher positioning accuracy compared with the traditional fingerprint algorithm.
An Integrated Load Balancing Scheme Based on SDN ASR Algorithm

At present, the flow table of the SDN switch is stored in the costly Ternary Content Addressable Memory (TCAM) cache. Due to the cost problem, the number of flow tables that the SDN switch can store is extremely limited, which is far less than the number of traffic, so it is prone to overflow problem, and leads to network paralysis. That has become a bottleneck in restricting the processing capacity of the data center, and will become a weak point focused by attackers. In this paper, we propose an algorithm for the Alarm Switch Remove (ASR) that fully loads the flow table space in SDN, and further put forward an integrated load balancing scheme in SDN. Finally, we use Mininet to verify that the scheme can ease the SDN switch flow table overflow problem and increase network throughput.
Waste fly ash-ZnO as a novel sunlight-responsive photocatalyst for dye discoloration

Treating waste with a waste material using freely available solar energy is the most effective way towards sustainable future.In this study,a novel photocatalyst,partly derived from waste material from the coal industry,was developed.Fly ash hybridized with ZnO (FA-Zn) was synthesized as a potential photocatalyst for dye discoloration.The synthesized photocatalyst was characterized by X-ray diffraction,scanning electron microscopy,transmission electron microscopy,and ultraviolet-visible/near infra-red spectroscopy.The photocatalytic activity was examined with the discoloration of methylene blue used as synthetic dye wastewater.All the experiments were performed in direct sunlight.The photocatalytic performance of FA-Zn was found to be better than that of ZnO and the conventionally popular TiO_2.The LangmuireHinshelwood model rate constant values of ZnO,TiO_2,and FA-Zn were found to be 0.016 min~(-1),0.017 min~(-1),and 0.020 min~(-1),respectively.There were two reasons for this:(1) FA-Zn was able to utilize both ultraviolet and visible parts of the solar spectrum,and (2) its BrunauereEmmetteTeller surface area and porosity were significantly enhanced.This led to increased photon absorption and dye adsorption,thus exhibiting an energy-efficient performance.Therefore,FA-Zn,partly derived from waste,can serve as a suitable material for environmental remediation and practical solar energy applications.
Effect of layer thickness on the flexural property and microstructure of 3Dprinted rhomboid polymer-reinforced cemented tailing composites

For mines with poor ore bodies and surrounding rocks,the general mining method does not allow the ore to be extracted from underground safely and efficiently.For these mines,the downward layered filling mining technique is undoubtedly the most suitable mining method.The downward filling mining technique may eliminate the troubles relating to poor ore deposit conditions,such as production safety,ore loss rate,and depletion rate.However,in this technique,the safety of the artificial roof of the next stratum is of paramount importance.Cementitious tailings backfilling (CTB) that is not sufficiently cemented and causes collapses could threaten ore production.This paper explores a diamond-shaped composite structure to mimic the stability of a glued false roof in an actual infill mine based on the recently emerged three-dimensional (3D) printing technology.Experimental means such as three-point bending and digital image correlation (DIC) techniques were used to explore the flexural characteristics of 3D construction specimens and CTB combinations with different cement/tailings weight ratios at diverse layer heights.The results show that the 3D structure with a 14-mm ply height and CTB has strong flexural characteristics,with a maximum deflection value of 30.1 mm,while the 3D-printed rhomboid polymer (3D-PRP) structure with a 26-mm ply height is slightly worse in terms of flexural strength characteristics,but it has a higher maximum flexural strength of 2.83 MPa.A combination of 3D structure and CTB has more unique mechanical properties than CTB itself.This research work offers practical knowledge on the artificial roof performance of the downward layered filling mining technique and builds a scientific knowledge base regarding the successful application of CTB material in mines.
A Meloidogyne incognita effector Minc03329 suppresses plant immunity and promotes parasitism

Meloidogyne incognita is a devastating plant-parasitic nematode. Effectors play important roles during the stages of nematodes infection and parasitism, but their molecular functions remain largely unknown. In this study, we characterized a new effector, Minc03329, which contains signal peptide for secretion and a C-type lectin domain. The yeast signal sequence trap experiments indicated that the signal peptide of Minc03329 is functional. In situ hybridization showed that Minc03329 was specifically expressed in the subventral esophageal gland. Real-time qPCR confirmed that the expression level of Minc03329 transcript was significantly increased in pre-parasitic and parasitic second-stage juveniles(pre-J2s and par-J2s). Tobacco rattle virus(TRV)-mediated gene silencing of Minc03329 in host plants largely reduced the pathogenicity of nematodes. On the contrary, ectopic expression of Minc03329 in Arabidopsis thaliana significantly increased plant susceptibility to nematodes. Transient expression of Minc03329 in Nicotiana benthamiana leaves suppressed the programmed cell death triggered by the pro-apoptotic protein BAX. Moreover, the transcriptome analysis of Minc03329-transgenic Arabidopsis and wild type revealed that many defense-related genes were significantly down-regulated. Interestingly, some different expressed genes were involved in the formation of nematode feeding sites. These results revealed that Minc03329 is an important effector for M. incognita, suppressing host defense response and promoting pathogenicity.
TIMP2 promotes intramuscular fat deposition by regulating the extracellular matrix in chicken

The interaction between myocytes and intramuscular adipocytes is a hot scientific topic. Using a co-culture system, this study aims to investigate the regulation of intramuscular fat deposition in chicken muscle tissue through the interaction between myocyte and adipocyte and identify important intermediary regulatory factors. Our proteomics data showed that the protein expression of tissue inhibitor of metalloproteinases 2(TIMP2)increased significantly in the culture medium of the co-culture system, and the content of lipid droplets was more in the co-culture intramuscular adipocytes. In addition, TIMP2 was significantly upregulated(P<0.01)in muscle tissue of individuals with high intramuscular fat content. Weighted gene co-expression network analysis revealed that TIMP2 was mainly involved in the extracellular matrix receptor interaction signaling pathway and its expression was significantly correlated with triglyceride, intramuscular fat,C14:0, C14:1, C16:0, C16:1, and C18:1n9C levels. Additionally, TIMP2 was co-expressed with various representative genes related to lipid metabolism(such as ADIPOQ, SCD, ELOVL5, ELOVL7, and LPL), as well as certain genes involved in extracellular matrix receptor interaction(such as COL1A2, COL4A2, COL5A1, COL6A1, and COL6A3), which are also significantly upregulated(P<0.05 or P<0.01)in muscle tissue of individuals with high intramuscular fat content. Our findings reveal that TIMP2 promotes intramuscular fat deposition in muscle tissue through the extracellular matrix receptor interaction signaling pathway.
Melatonin treatment alleviates chilling injury in mango fruit 'Keitt' by modulating proline metabolism under chilling stress

Mangoes often suffer from low temperature-induced chilling injury(CI)during postharvest cold storage. Therefore,advanced techniques are crucial and in high demand to solve the chilling stress of mango fruit for a higher value. This study addresses chilling stress modulation by investigating the effects of melatonin treatment on CI, proline metabolism,and related gene expressions of 'Keitt' mango during cold storage after dipped in 0(control), 0.1(MT1), and 0.2 mmol L~(-1)(MT2)melatonin solution for 30 min. The results revealed that melatonin treatment in MT1 significantly reduced CI development and increased proline content in mango fruit during cold storage compared to the control. These changes were along with increases in the activity of critical enzymes as well as the expression of encoding genes involved in proline biosynthesis, such as pyrroline-5-carboxylate synthetase(P5CS), pyrroline-5-carboxylate reductase(P5CR),ornithine D-aminotransferase(OAT), P5CS2, P5CR2, and OAT3. Additionally, proline dehydrogenase(PDH)activity and the expression of the PDH3 gene associated with proline dehydrogenation were lower in MT1-treated mangoes than the controlled group. Thus, melatonin treatment has regulated proline metabolism resulting in the accumulation of proline,subsequently contributing to enhancing the chilling tolerance of 'Keitt' mango fruit.
Online Optimization in Power Systems With High Penetration of Renewable Generation:Advances and Prospects

Traditionally,offline optimization of power systems is acceptable due to the largely predictable loads and reliable generation.The increasing penetration of fluctuating renewable generation and internet-of-things devices allowing for fine-grained controllability of loads have led to the diminishing applicability of offline optimization in the power systems domain,and have redirected attention to online optimization methods.However,online optimization is a broad topic that can be applied in and motivated by different settings,operated on different time scales,and built on different theoretical foundations.This paper reviews the various types of online optimization techniques used in the power systems domain and aims to make clear the distinction between the most common techniques used.In particular,we introduce and compare four distinct techniques used covering the breadth of online optimization techniques used in the power systems domain,i.e.,optimization-guided dynamic control,feedback optimization for single-period problems,Lyapunov-based optimization,and online convex optimization techniques for multiperiod problems.Lastly,we recommend some potential future directions for online optimization in the power systems domain.
Robust structured light in atmospheric turbulence

Structured light is routinely used in free-space optical communication channels, both classical and quantum, where information is encoded in the spatial structure of the mode for increased bandwidth. Both real-world and experimentally simulated turbulence conditions have revealed that free-space structured light modes are perturbed in some manner by turbulence, resulting in both amplitude and phase distortions, and consequently, much attention has focused on whether one mode type is more robust than another, but with seemingly inconclusive and contradictory results. We present complex forms of structured light that are invariant under propagation through the atmosphere: the true eigenmodes of atmospheric turbulence. We provide a theoretical procedure for obtaining these eigenmodes and confirm their invariance both numerically and experimentally. Although we have demonstrated the approach on atmospheric turbulence, its generality allows it to be extended to other channels too, such as aberrated paths, underwater, and in optical fiber.
微生物在海水循环水养殖系统中的作用及其应用进展

近50年来,水产养殖已从小规模商业模式发展到大型规模化养殖模式,数据显示,通过养殖收获的水产品自20世纪70年代初仅占水产品消费总量的6%升到2018年的46%。而全球人口不断增加进一步加大对养殖水产品的需求量。随着养殖密度的不断提升及水资源的无序利用,开放式流水工厂化养殖模式暴露出地下井水资源遭受破坏、病害逐年增多、食品安全等问题,加之沿海工业用地挤压和全球倡导节能减排等多重压力,其发展已经面临一个新的瓶颈,养殖模式亟待转变。在此基础上,一种全新概念的封闭式工厂化循环水养殖系统模式应运而生,它可以充分利用有限的环境资源条件实现养殖的可持续性发展。循环水养殖系统可以在最佳条件下,对养殖生物活动产生的排泄物进行高效管理、收集和处理,除蒸发损失和补充微滤机反冲水外,全程无需添加新水。
声带轻瘫诊疗进展

声带轻瘫或声带不全麻痹(vocal fold paresis)是一种复杂的声带运动障碍,以前,耳鼻喉科医生认为声带麻痹是一种全或无现象,表现为声带不动、完全没有神经输入。然而,电生理学研究表明,声带麻痹是一种异常复杂的异质化的临床症状。声带完全麻痹是声带完全没有神经输入和声带静止,而声带轻瘫包括不同程度的神经损伤,声带活动度大体保留。Vocal fold paresis这个名词首先在2000年由Koufman描述,它的发生率、诊断和治疗策略一直是争论的热点。临床上,声带轻瘫的特点尚未完全阐明,其诊断标准也不明确。声带功能的神经源性损伤包括不同程度和不同模式的去神经支配,声带轻瘫可能是发声功能障碍的一个重要原因,它表现为发声功能不全的症状,临床过程可能类似于声带瘫痪。声带轻瘫可能对患者的发声、吞咽和呼吸功能有相当大的影响。声带完全麻痹的患者,发声时声门闭合不全是很明显的,而声带轻瘫的患者,轻微的神经肌肉功能障碍可能会被忽略,因此,容易误诊为原发性功能性发声障碍。本文就声带轻瘫的发病率、病因、临床表现、诊断及治疗的最新研究进展进行综述,以进一步加深临床医生对此的认识。
