重视外科出院后病人的营养管理

营养风险与营养不良是住院病人面临的重要问题,诸多证据表明,给予高营养风险和营养不良病人合理的营养支治疗可以改善病人的临床结局。对于外科病人,医学营养在围手术期处理中更起到了至关重要的作用。随着医学营养认识的不断提高,病人在医院期间营养问题日益得到重视,围手术期营养支持措施也在不断改进,但是,仍有相当数量的病人营养状况变得比入院时更差。出院后病人离开了医院,脱离了医务人员的监管,难以进行规范化的营养管理,更有一些肿瘤病人,手术后还要进行化疗、放疗、免疫等治疗,这些治疗会影响病人的胃肠道功能,影响营养物质的摄入、消化和吸收,使得病人营养状况进一步恶化。这种状况在外科ERAS年代显得更为突出。出院后病人的营养问题往往得不到足够的重视,使得病人出院后恢复延缓,后续治疗也会受到影响。今就相关问题讨论如下。

Phoenix phylogeny,and analysis of genetic variation in a diverse collection of date palm (Phoenix dactylifera) and related species

Date palm (Phoenix dactylifera),one of the most ancient crops,is grown commercially in >30 countries.Using whole plastome assemblies,phylogenetic analyses revealed that cultivated date palm accessions share the same clade with Phoenix sylvestris,Phoenix pusilla and Phoenix acaulis,which are native to the Indian subcontinent,and Phoenix caespitosa that is native to the Arabian Peninsula and the deserts of Somalia.Analysis of genetic diversity and genetic relationships among date palm accessions from 13 producing countries involved 195 date palm accessions that were genotyped at 19 microsatellite loci.Extensive genetic diversity was observed,with many accessions heterozygous for most markers in this clonally propagated crop.The average number of alleles per locus (42.1),expected heterozygosity (0.8),observed heterozygosity (0.47) and fixation indices (F_(ST) = 0.42) demonstrated substantial genetic diversity and population structure.Iraqi accessions were found to have the richest allelic diversity,and the most private alleles.The model-based Bayesian method indicated that these accessions could be broadly divided into two structure groups,one group with predominantly African accessions and another predominantly Asian.Some germplasm,especially from Tunisia and Iraq,deviated from this generalization.Many accessions in the STRUCTURE-derived groups were found to be genetic admixtures,with gene flow between Asian and African groups.Indian and Pakistani date palms were found to be most closely related to North African germplasm.
Cell number explains the intraspecific spur-length variation in an Aquilegia species

Variations of nectar spur length allow pollinators to utilize resources in novel ways,leading to the different selective pressures on spurs and allowing taxa to diversify.However,the mechanisms underlying spur length variation remain unclear.Interspecific comparisons of spur length suggest that both cell division and anisotropic expansion could explain the changes of spur length,and that hormone-related genes contribute to the process of spur formation.In contrast,little is known about intraspecific spur length variation.In Aquilegia rockii,spur length varies strikingly,ranging from 1 mm to 18 mm.To examine the potential mechanisms underlying spur length variation in A.rockii,we observed cell morphology and analyzed RNA-seq of short-and long-spurred flowers.Scanning electron microscopy revealed that at two positions on spurs there were no differences in either cell density or cell anisotropy between short-and long-spurred flowers,suggesting that in A.rockii changes in cell number may explain variations in spur length.In addition,we screened transcriptomes of short-and long-spurred flowers for differentially expressed genes;this screen identified several genes linked to cell division (e.g.,F-box,CDKB2-2,and LST8),a finding which is consistent with our analysis of the cellular morphology of spurs.However,we did not find any highly expressed genes involved in the hormone pathway in long-spurred flowers.In contrast to previous hypotheses that anisotropic cell expansion leads to interspecific spur variation in Aquilegia,our results suggest that cell number changes and related genes are mainly responsible for spur length variations of A.rockii.Furthermore,the underlying mechanisms of similar floral traits in morphology may be quite different,enriching our understanding of the mechanisms of flower diversity in angiosperms.
Yield models for predicting aboveground ectomycorrhizal fungal productivity in Pinus sylvestris and Pinus pinaster stands of northern Spain

Background: Predictive models shed light on aboveground fungal yield dynamics and can assist decision-making in forestry by integrating this valuable non-wood forest product into forest management planning. However, the currently existing models are based on rather local data and, thus, there is a lack of predictive tools to monitor mushroom yields on larger scales. Results: This work presents the first empirical models for predicting the annual yields of ectomycorrhizal mushrooms and related ecosystem services in Pinus sylvestris and Pinus pinaster stands in northern Spain, using a long-term dataset suitable to account for the combined effect of meteorological conditions and stand structure. Models were fitted for the following groups of fungi separately: all ectomycorrhizal mushrooms, edible mushrooms and marketed mushrooms. Our results show the influence of the weather variables (mainly precipitation) on mushroom yields as well as the relevance of the basal area of the forest stand that follows a right-skewed unimodal curve with maximum predicted yields at stand basal areas of 30–40 m~2·ha~(– 1). Conclusion: These models are the first empirical models for predicting the annual yields of ectomycorrhizal mushrooms in Pinus sylvestris and Pinus pinaster stands in northern Spain, being of the highest resolution developed to date and enable predictions of mushrooms productivity by taking into account weather conditions and forests’ location, composition and structure.
Comparative FISH and molecular identification of new stripe rust resistant wheat-Thinopyrum intermedium ssp. trichophorum introgression lines

Thinopyrum intermedium (2n = 6x = 42, JJJ~sJ~sStSt) has been hybridized extensively with common wheat and has proven to be a valuable germplasm source for improving disease resistance, quality attributes, and yield potential in wheat. We characterized new disease resistant wheat-Th. intermedium derivatives A1082 and A5-5 using sequential multi-color fluorescence in situ hybridization (mc-FISH), genomic in situ hybridization (GISH), PCRbased landmark unique gene (PLUG) and intron targeting (IT) markers. A1082 was identified as a wheat-Th. intermedium 3J disomic addition line, and A5-5 was a T4BS·5J~sL homozygous Robertsonian translocation line. Seventy-one and 106 pairs of primers amplified Th. intermedium-specific bands allowing chromosomes 3J and 5J~s to be tracked, respectively. A new oligonucleotide probe, Oligo-6H-2-100, was developed for FISH labeling of the subterminal region of the long arm of chromosome 5J~s. Both lines were highly resistant to stripe rust pathogen races prevalent in Chinese field screening nurseries. A5-5 also displayed a significant increase in tiller number compared to its wheat parent. The new lines can be exploited as useful germplasms for wheat improvement.
Precipitation and seasonality affect grazing impacts on herbage nutritive values in alpine meadows on the Qinghai-Tibet Plateau

Aims Grasslands used for animal husbandry are chosen depending on the nutritive values of dominant herbage species. However, the influence of grazing in combination with precipitation and growing season on the nutritive values of dominant species has not been explicated. Methods To unveil the influence of the different grazing intensities on the nutritional values, an ecological study was formulated, namely fencing (G0), light grazing (G1), moderate grazing (G2) and high grazing (G3). This ambitious study was undertaken on the nutritive values of the four dominant species of herbage in an alpine meadow on the Qinghai-Tibet Plateau (QTP) during growing season (June–September) for two successive years, namely 2015 (rainy year) and 2016 (droughty year). Important Findings We found that (i) the nutritive value of Kobresia capillifolia, Polygonum viviparum and Caragana sinica was noticeably increased by grazing, but negligible effect on Potentilla fruticosa nutritive value was recorded. (ii) During the rainy year (2015), compared with G0, Polygonum viviparum and Potentilla fruticosa displayed 5.4 and 1.5% increases in the crude protein (CP) content and 8.5 and 2.4% increases in vitro true digestibility (IVTD), respectively, while the neutral detergent fibre (NDF) decreased by 13.5 and 0.9%, respectively. During the droughty year (2016), compared with G0, C. sinica and Potentilla fruticosa showed increases in the CP content by 4.3 and 1.3% and increases in the IVTD by 10.7 and 0.4%, respectively, during G3, while the NDF decreased by 6.0 and 1.0%, respectively. (iii) The nutritive values of all species were higher in the years when the rains were good. However, the nutritive values suffered heavily during drought conditions. Besides, the highest and lowest values of nutrition were detected in June and in September, respectively. The inter-seasonal and the inter-annual changes in the nutritional values of species were higher for K. capillifolia and Polygonum viviparum than for Potentilla fruticosa and C. sinica, suggesting that Potentilla fruticosa and C. sinica had higher water-use efficiency. (iv) Grazing clearly reduced the drought tolerance of three species and showed no effects on Potentilla fruticosa. (v) Grazing clearly increased the inter-month variation in the nutritional value of K. capillifolia and Polygonum viviparum but showed no effects on Potentilla fruticosa or C. sinica. Evidently, the grazing effects impacting the nutritional value of the dominant species of herbage exhibited conspicuous inter-annual and seasonal variations with species-specific influences and responses. Our findings are expected to have far-reaching implications enabling the authorities to arrive at strategic decisions and designing of relevant policies for the efficient management of the ecosystems ensuring the speed restoration of the QTP under severe grazing and extreme climatic circumstances.
Neural network-based model for prediction of permanent deformation of unbound granular materials

Several available mechanistic-empirical pavement design methods fail to include predictive model for permanent deformation(PD)of unbound granular materials(UGMs), which make these methods more conservative. In addition, there are limited regression models capable of predicting the PD under multistress levels, and these models have regression limitations and generally fail to cover the complexity of UGM behaviour. Recent researches are focused on using new methods of computational intelligence systems to address the problems, such as artificial neural network(ANN). In this context, we aim to develop an artificial neural model to predict the PD of UGMs exposed to repeated loads. Extensive repeated load triaxial tests(RLTTs)were conducted on base and subbase materials locally available in Victoria, Australia to investigate the PD properties of the tested materials and to prepare the database of the neural networks. Specimens were prepared over different moisture contents and gradations to cover a wide testing matrix. The ANN model consists of one input layer with five neurons, one hidden layer with twelve neurons, and one output layer with one neuron. The five inputs were the number of load cycles, deviatoric stress, moisture content, coefficient of uniformity, and coefficient of curvature. The sensitivity analysis showed that the most important indicator that impacts PD is the number of load cycles with influence factor of 41%. It shows that the ANN method is rapid and efficient to predict the PD, which could be implemented in the Austroads pavement design method.
Early acceleration of electrons and protons at the nonrelativistic quasiparallel shocks with different obliquity angles

The early acceleration of protons and electrons in the nonrelativistic collisionless shocks with three obliquities are investigated through 1D particle-in-cell simulations. In the simulations, the charged particles possessing a velocity of 0.2 c flow towards a reflecting boundary, and the shocks with a sonic Mach number of 13.4 and an Alfven Mach number of 16.5 in the downstream shock frame are generated. In these quasi-parallel shocks with the obliquity angles θ = 15◦, 30◦ and 45◦, some of the protons and the electrons can be injected into the acceleration processes, and their downstream spectra in the momentum space show a power law tail at a time of 1.89×10~5 ω~(-1)_(pe), where ω_(pe) is the electron plasma frequency. Moreover, the charged particles reflected at the shock excite magnetic waves upstream of the shock. The shock drift acceleration is more prominent with a larger obliquity angle for the shocks, but the accelerated particles diffuse parallel to the shock propagation direction more easily to participate in the diffusive shock acceleration. In the early acceleration stage, more energetic protons and electrons appear in the downstream of the shock for θ = 15◦ compared with the other two obliquities. Moreover, in the upstream region, the spectrum of the accelerated electrons is the hardest for θ_(nB) = 45◦ among the three obliquities, whereas the proton spectra for θ_(nB) = 15◦ and 45◦ are similar as a result of the competition of the effectiveness of the shock drift acceleration and the diffusive shock acceleration.

Novel expanded porphyrinoids with multiple-inner-ring-fusion and/or tunable aromaticity

Novel expanded porphyrinoids with advanced structure features(such as multiple-inner-ring-fusion)have a wide range of benefits(such as multi-metal coordination and facile tunable aromaticity)not offered by their normal porphyrin analogues, and have found wide applications as sensors, fluorescent probes, novel ligands and functionalized NIR organic dyes in various research fields. However, the structures of these expanded porphyrinoids are scarce due to their limited synthetic accessibility. Herein, we summarized the lately reported efficient synthesis of novel expanded porphyrinoids with multiple-inner-ring-fusion(up to six-inner-ring-fusion)and smaragdyrins with tunable aromaticity. Their synthesis is either based on an oxidative ring cyclization on linear/macrocyclic oligopyrroles containing N-confused pyrrole unit(s)or a straightforward double S_NAr reaction on readily available3,5-dibromoBODIPY, respectively.
Enhanced graph-based fault diagnostic system for nuclear power plants

Scheduled maintenance and condition-based online monitoring are among the focal points of recent research to enhance nuclear plant safety. One of the most effective ways to monitor plant conditions is by implementing a full-scope, plant-wide fault diagnostic system. However, most of the proposed diagnostic techniques are perceived as unreliable by operators because they lack an explanation module, their implementation is complex, and their decision/inference path is unclear. Graphical formalism has been considered for fault diagnosis because of its clear decision and inference modules, and its ability to display the complex causal relationships between plant variables and reveal the propagation path used for fault localization in complex systems. However, in a graphbased approach, decision-making is slow because of rule explosion. In this paper, we present an enhanced signed directed graph that utilizes qualitative trend evaluation and a granular computing algorithm to improve the decision speed and increase the resolution of the graphical method. We integrate the attribute reduction capability of granular computing with the causal/fault propagation reasoning capability of the signed directed graph and comprehensive rules in a decision table to diagnose faults in a nuclear power plant. Qualitative trend analysis is used to solve the problems of fault diagnostic threshold selection and signed directed graph node state determination. The similarity reasoning and detection ability of the granular computing algorithm ensure a compact decision table and improve the decision result. The performance of the proposed enhanced system was evaluated on selected faults of the Chinese Fuqing2 nuclear reactor. The proposed method offers improved diagnostic speed and efficient data processing. In addition, the result shows a considerable reduction in false positives, indicating that the method provides a reliable diagnostic system to support further intervention by operators.

循证实践(evidence-based practice, EBP)是指在有最佳科研证据的基础下提供卫生保健的一种方式,是将患者利益作为医学服务的中心,正确识别临床问题并应用最佳干预措施,其告别了以经验和推理为主的传统医学模式。腰痛(low back pain, LBP)主要指低位肋骨边缘以下至臀纹以上区域的疼痛综合征,通常伴有一侧或双侧下肢的疼痛症状。流行病学表明:人一生中腰痛的终生患病率高达85%,其中慢性腰痛为23%,致残率达11%—12%。腰痛已成为世界范围内活动受限和工作缺勤的首要原因,给社会造成了巨大的经济负担,也将成为全球人口致残的主要原因。目前,WHO将“减少致残性腰痛”列入实现全球健康的目标之一,并呼吁使腰痛相关研究成为“全球健康”的优先项目。我国尚缺乏腰痛循证康复治疗指南,关于腰痛的康复治疗还存在盲目治疗和过度治疗等问题,其相关研究文献有待补充完善。本文主要解读国际上四项权威腰痛循证康复治疗指南,并比较各指南的腰痛评估与管理的差异,以期为我国腰痛康复治疗方案的开展提供参考。
Effect of RANS Turbulence Model on Aerodynamic Behavior of Trains in Crosswind

The numerical simulation based on Reynolds time-averaged equation is one of the approved methods to evaluate the aerodynamic performance of trains in crosswind. However, there are several turbulence models, trains may present different aerodynamic performances in crosswind using different turbulence models. In order to select the most suitable turbulence model, the inter-city express2(ICE2)model is chosen as a research object,6 different turbulence models are used to simulate the flow characteristics, surface pressure and aerodynamic forces of the train in crosswind,respectively.6 turbulence models are the standard k-ε, Renormalization Group(RNG)k-ε, Realizable k-ε, Shear Stress Transport(SST)k-ω, standard k-ω and Spalart–Allmaras(SPA), respectively. The numerical results and the wind tunnel experimental data are compared. The results show that the most accurate model for predicting the surface pressure of the train is SST k-ω, followed by Realizable k-ε. Compared with the experimental result, the error of the side force coefficient obtained by SST k-ω and Realizable k-ε turbulence model is less than1 %. The most accurate prediction for the lift force coefficient is achieved by SST k-ω, followed by RNG k-ε. By comparing6 different turbulence models, the SST k-ω model is most suitable for the numerical simulation of the aerodynamic behavior of trains in crosswind.

Novel radioligands for imaging sigma-1 receptor in brain using positron emission tomography(PET)

The sigma-1 receptor(σ_1R)is a unique intracellular protein. σ_1R plays a major role in various pathological conditions in the central nervous system(CNS), implicated in several neuropsychiatric disorders. Imaging of σ_1R in the brain using positron emission tomography(PET)could serve as a noninvasively tool for enhancing the understanding of the disease's pathophysiology. Moreover, σ_1R PET tracers can be used for target validation and quantification in diagnosis. Herein, we describe the radiosynthesis, in vivo PET/CT imaging of novel σ_1R ~(11)C-labeled radioligands based on 6-hydroxypyridazinone, [~(11)C]HCC0923 and [~(11)C]HCC0929. Two radioligands have high affinities to σ_1R, with good selectivity. In mice PET/CT imaging, both radioligands showed appropriate kinetics and distributions. Additionally, the specific interactions of two radioligands were reduced by compounds 13 and 15(self-blocking). Of the two, [~(11)C]HCC0929 was further investigated in positive ligands blocking studies, using classic σ_1R agonist SA 4503 and σ_1R antagonist PD 144418. Both σ_1R ligands could extensively decreased the uptake of [~(11)C]HCC0929 in mice brain. Besides, the biodistribution of major brain regions and organs of mice were determined in vivo. These studies demonstrated that two radioligands, especially [~(11)C]HCC0929, possessed ideal imaging properties and might be valuable tools for non-invasive quantification of σ_1R in brain.

Evolution of landscape in a piedmont section of Eastern Himalayan foothills along India-Bhutan border: A tectonogeomorphic perspective

The present study area involves part of a deformed coalesced fan located along the Himalayan Frontal Thrust (HFT) on the east of river Tista near the India-Bhutan border. The area is marked by two spectacular E-W trending south-sloping scarps namely the Matiali (ca. 60 m) and Chalsa (ca. 90 m) Scarps and a north-sloping E-W trending Thaljhora (ca. 80 m) Scarp. Our work comprises of a comparative study of geomorphology and geologic history in the adjacent interfluves of Jaldhaka-Gathia and Neora-Murti rivers to understand the tectonic history of the area. We mapped the Jaldhaka-Gathia river interfluve at a 1:25,000 scale and report a hitherto unidentified northerly sloping small scarp of ca. 5m height named the Nagrakata Scarp. This scarp was identified using satellite images, DEMs, and total station survey. We interpret that the two northsloping, E-W trending scarps (Thaljhora and Nagrakata Scarps) are manifestations of steep limbs of anticlines over blind south-dipping back thrusts. Together they form a wrinkle-ridge pair behind the north-dipping HFT, which is manifested by southsloping Chalsa Scarp. We propose a plausible geomorphic model interpreting that deformation along the small fan in the Jaldhaka-Gathia interfluves is younger compared to fan deposition and deformation in the adjacent Mal-Murti interfluve. The most recent geomorphology of the Jaldhaka-Gathia interfluve is controlled by tectonism associated with the thrust below the Nagrakata Scarp where the youngest deformation episode is recorded to at around ~6 ka and is likely related to motion on a splay off of the thrust beneath the Thaljhora Scarp.
