目的了解重庆市长寿区居民膳食模式及其与高尿酸血症的关系,为高尿酸血症的预防控制提供参考依据。方法2018年9—12月采用分层整群抽样方法在长寿区抽取1004名30~79岁成年居民进行问卷调查、体格检查和实验室检测;采用因子分析提取膳食模式,采用多因素logistic回归模型分析膳食模式与高尿酸血症的关系。结果长寿区30~79岁居民高尿酸血症患病率为10.36%,因子分析得出4种膳食模式,分别为蛋奶水果模式、肉食模式、素食模式和主食模式,累计方差贡献率为41.58%。在调整相关混杂因素后发现,高水平肉食模式是高尿酸血症的危险因素(OR=2.39,95%CI:1.27~4.52);高水平素食模式是高尿酸血症的保护因素(OR=0.53,95%CI:0.29~0.98)。结论重庆市长寿区居民的肉食模式与素食模式与高尿酸血症患病密切相关,应推广健康膳食模式。

血液透析是终末期尿毒症患者常用的肾脏替代疗法之一,但长期血液透析可导致患者出现焦虑或抑郁等心理问题。中医药治疗血液透析伴焦虑或抑郁障碍的方法包括中医内治法、中医外治法、复合疗法等。其中,中医内治法包括经方疗法、时方疗法、自拟方疗法、中成药疗法等;中医外治法包括穴位疗法、中药足浴、五行音乐疗法、运动疗法等;复合疗法联合中药内服外治及常规西药和护理,疗效优于单一治疗。目前的研究仍存在一些不足,如缺乏规范的辨证分型、作用机制尚不明确、临床样本量有限、缺乏严谨的随机对照试验等。今后,应扩大样本量,严格实施随机对照试验,并探索具体的作用机制,以提供更多高质量的证据支持中医药治疗血液透析伴焦虑或抑郁障碍的临床效果。此外,中医外治法应成为血液透析伴焦虑、抑郁障碍的重点研究方向之一。

Fengyun-3 E(FY-3E),the world’s first early-morning-orbit meteorological satellite for civil use,was launched successfully at the Jiuquan satellite Launch Center on 5 July 2021.The FY-3E satellite will fill the vacancy of the global early-morning-orbit satellite observation,working together with the FY-3C and FY-3D satellites to achieve the data coverage of early morning,morning,and afternoon orbits.The combination of these three satellites will provide global data coverage for numerical weather prediction(NWP)at 6-hour intervals,effectively improving the accuracy and time efficiency of global NWP,which is of great significance to perfect the global earth observing system.In this article,the background and meteorological requirements for the early-morning-orbit satellite are reviewed,and the specifications of the FY-3E satellite,as well as the characteristics of the onboard instrumentation for earth observations,are also introduced.In addition,the ground segment and the retrieved geophysical products are also presented.It is believed that the NWP communities will significantly benefit from an optimal temporal distribution of observations provided by the early morning,mid-morning,and afternoon satellite missions.Further benefits are expected in numerous applications such as the monitoring of severe weather/climate events,the development of improved sampling designs of the diurnal cycle for accurate climate data records,more efficient monitoring of air quality by thermal infrared remote sensing,and the quasicontinuous monitoring of the sun for space weather and climate.

Three-dimensional(3D)functional graphenebased architecture with superior electrical conductivity and good mechanical strength has promising applications in energy storage and electrics.Viscoelasticity-adjustable inks make it possible to achieve desired 3D architectures with interconnected and continuous interior networks by microextrusion printing.In this work,ultra-low-concentration graphene oxide(GO)inks of~15 mg·ml-1 have been obtained and demonstrated in direct 3D printing with a facile cross-linking(direct ink writing).The rheological behavior of the GO strategy by cations,which is the lowest concentration to achieve direct ink writing inks,could be adjusted from 1×10^(4) to 1×10^(5) Pa·s^(-1) with different concentrations of cations due to strong cross-linking networks between GO sheets and cations.Meanwhile,the specific strength and electrical conductivity of 3D-printed graphene architecture are notably enhanced,reaching up to 51.7×10^(3) N·m·kg^(-1)and 119 S·m^(-1),which are superior to conventional graphene aerogels.Furthermore,3D printing graphene-based architecture assembled in micro-superc apacitor exhibits excellent electrochemical performance,which can be ascribed to the effective ion transportation through the interconnected networks.The strategy demonstrated is useful in the design of complex-shaped,graphene-based architectures for scalable manufacturing of practical energy storage applications.

The quantification of phosphorus(P) in bulk soil and P distribution in different size fractions of water-stable aggregates(Wsas)are important for assessing potential P loss through runoff. We evaluated available and total P distribution within Wsas of a sitty clay to clay soil in a long-term fertility experiment of a rice-wheat cropping system in India. Surface soil samples were collected from seven plots amended with NPK fertilizers in combination with or without organic amendments, farmyard manure(FYM), green manure(GM), and paddy straw(PS). The plot with no NPK fertilizers or organic amendments was set as a control. The soil samples were separated by wet sieving into four soil aggregate size fractions: large macroaggregates(> 2.0 mm), small macroaggregates(0.25–2.0 mm), fine microaggregates(0.05–0.25 mm), and a silt + clay-sized fraction(sas were inversely related to the aggregate size, irrespective of treatment. The distribution of available and total P in the soil aggregate size fraction was as follows: silt + clay-size fraction > small macroaggregates > fine microaggregates> large macroaggregates. Within a size class, aggregate-associated available and total P contents in the organically amended soil were in the following order: FYM > PS ≥ GM. The available P content of the microaggregates( 0.25 mm), and the total P content of the microaggregates was 4-to 5-times higher than that of the macroaggregates. Cultivation without organic amendments resulted in more microaggregates that could be checked by the application of organic amendments such as FYM and GM, which increased the proportion of

Arsenic(As)contamination in soil and water poses a serious threat to the ecosystem health and human beings,and is of widespread concern.The main As species found in soil and water are arsenite As(Ⅲ)and arsenate As(V).Because As(Ⅲ)is more toxic and often more mobile than As(Ⅴ),many remediation strategies aim to oxidize As(Ⅲ)to As(Ⅴ).In the environment,the reduction of As(Ⅴ)under anaerobic conditions is mainly mediated by microorganisms,but the oxidation of As(Ⅲ)under aerobic conditions can be mediated primarily by chemical processes.This article first reviews the existing knowledge on chemical oxidation of As(Ⅲ)in the environment,with an emphasis on the roles of iron(Fe)and manganese(Mn)oxides.The application of Fe and Mn oxides for the remediation of As-contaminated soil and water is then summarized.The oxidation of As(Ⅲ)by oxygen is very slow in the absence of catalysts.Many Mn oxides,on the other hand,can efficiently oxidize As(Ⅲ).Although the oxidation of As(Ⅲ)by Fe(Ⅲ)is also slow,this process can be accelerated by light or Fe(Ⅱ).Iron and Mn oxides are widely used for the remediation of As-contaminated soil and water,with Fe oxides generally acting as absorbents while Mn oxides as oxidants.To better understand and regulate As transformation and transport in the environment,further study is needed on the mechanisms and influencing factors of As(Ⅲ)oxidation by Fe and Mn oxides,and the development of innovative methods and materials based on Fe and Mn oxides are desired.
