探究数字普惠金融能否富民增收对实现共同富裕具有重要意义。基于拓展的内生经济增长模型,本文构建一个数字普惠金融影响农民收入的理论分析框架,并利用2014—2020年长江经济带县域数据实证研究数字普惠金融对农民收入的影响机制、作用渠道与空间溢出效应。研究结果显示,数字普惠金融能够增加农民收入;从细分维度看,数字普惠金融的覆盖广度和使用深度对农民收入存在促进作用,而且覆盖广度的促进作用更强。农业技术进步、农民物质资本积累和农村人力资本积累是数字普惠金融促进农民收入增加的重要传导路径。异质性分析发现,长江经济带下游县域数字普惠金融对农民的增收效果最强,中游其次,上游最弱,而且对于收入水平高、人口规模大和耕地规模大的县域,数字普惠金融对农民的增收效应更强。从空间视角来看,数字普惠金融具有空间溢出效应且存在明显的溢出边界。本文研究结论为农民增收提供了基于数字普惠金融发展视角的经验证据与政策启示。

“家国同构”是国家治理的特征和底色,文章将衡量家庭富裕程度的恩格尔系数引入财政领域,构建财政恩格尔系数,借此对地方财政困难作出新解释,利用2007—2020年中国31个省(区、市)的面板数据,估计出该系数的最优区间,并实证检验其是否符合传统恩格尔定律。研究发现:(1)基于财力配置过程和财政支出次序,将财政恩格尔系数定义为地方教育、社会保障和就业、一般公共服务支出占地方一般公共预算支出的比重,并根据取值情况与地方财政贫富程度相对应,得出“中等地区”现象的基本判定。(2)当财政恩格尔系数介于0.25和0.36之间时,将对促进经济社会发展产生最大效应,但在样本观测期内只有部分直辖市和民族地区的系数满足此区间。(3)财政恩格尔系数随着地方可支配财力的增加而下降,但当地方可支配财力达到一定规模时,其下降幅度趋缓,基本符合传统恩格尔定律。为此,建议短期应开源节流注入资金流动性,中长期应统筹谋划破除体制障碍。

尿潴留通常被定义为膀胱充盈状态下排空能力受损导致排尿后残余尿量增加。临床中术后尿潴留(POUR)没有标准定义。与其他盆腔手术相比,尿失禁手术和脱垂手术POUR的发生率最高。其临床表现多样,体格检查可触及充盈的膀胱。早期识别POUR非... 详细信息

尿潴留通常被定义为膀胱充盈状态下排空能力受损导致排尿后残余尿量增加。临床中术后尿潴留(POUR)没有标准定义。与其他盆腔手术相比,尿失禁手术和脱垂手术POUR的发生率最高。其临床表现多样,体格检查可触及充盈的膀胱。早期识别POUR非常关键,推荐使用逆行检查法或自主排尿法在患者出院前进行检测。对于诊断为尿潴留的患者,推荐采用留置导尿管或清洁间歇性导尿术持续导尿,直至症状缓解。药物治疗及非药物干预治疗对于尿潴留也有一定治疗作用。当以上处理方法无法解决POUR时,可能需要更积极的手术处理。

AIM To identify circulating micro(mi)RNAs as biological markers for prediction of severe acute pancreatitis(SAP) with acute lung injury(ALI).METHODS Twenty-four serum samples were respectively collected and classified as SAP associated with ALI and SAP without ALI, and the mi RNA expression profiles were determined by microarray analysis. These mi RNAs were validated by quantitative reverse transcriptionpolymerase chain reaction, and their putative targets were predicted by the online software Target Scan, mi Randa and Pic Tar database. Gene ontology(GO) and Kyoto encyclopedia of genes and genomes(commonly known as KEGG) were used to predict their possible functions and pathways *** We investigated 287 mi RNAs based on microarray data analysis. Twelve mi RNAs were differentially expressed in the patients with SAP with ALI and those with SAP without ALI. Hsa-mi R-1260 b, 762, 22-3 p, 23 b and 23 a were differently up-regulated and hsa-mi R-550 a*, 324-5 p, 484, 331-3 p, 140-3 p, 342-3 p and 150 were differently down-regulated in patients with SAP with ALI compared to those with SAP without ALI. In addition, 85 putative target genes of the significantly dysregulated mi RNAs were found by Target Scan, mi Randa and Pic Tar. Finally, GO and pathway network analysis showed that they were mainly enriched in signal transduction, metabolic processes, cytoplasm and cell *** This is the first study to identify 12 circulating mi RNAs in patients with SAP with ALI, which may be biomarkers for prediction of ALI after SAP.

5 different forests of Pinus massoniana, Schima superba, Liquidambar formosana, P. massoniana × S. superba, P. massoniana × L. formosana as the research object were set up to study the Cr, Cu and Zn content of degraded red soil region in subtropics. The soil heavy metal pollution degree was evaluated by national environmental quality standard (II class). The results showed that three soil metals of P. massoniana × S. superba were the highest, and the soil metals enrichment ability was strong. The order of single factor pollution index of metal elements was Cu (1.38) > Cr (0.81) > Zn (0.42), and moderately pollution, pollution warning and no pollution, respectively. There was no significant correlation between three soil heavy metals and soil total carbon (TC), total nitrogen (TN) and total phosphorus (TP). These results suggested that the accumulation of heavy metal elements was not derived from the parent material of soil. There was a significant positive correlation between the three metal elements which indicated that the sources of the three elements were similar. The structural equation model showed that the direct and indirect effects among the influencing factors ultimately affected the activity of heavy metals by cascade effects.

A yield gap analysis for rapeseed(Brassica napus L.) is critical to meeting the oil demand by identifying yield potential and yield constraints. In this study, potential yield(Y_p), attainable yield(Y_(att)), and actual yield(Y_(act)) for winter rapeseed were determined in five different zones of China. A boundary line approach was adopted to calculate Y_p, based on a large-scale field experimental database. A meta-analysis was conducted on the data obtained from 118 published studies to evaluate the effects of agronomic factors on rapeseed yield. The main results indicated that farmers only achieved 37–56% of the yield potential across the zones. The low altitude areas(L-URY) and lower reaches(LRY) of the Yangtze River Basin(YRB), China had high yield levels. The total yield gap was 1 893 kg ha^(–1), due to the agronomic management factors, environmental factors, and socioeconomic factors. The meta-analysis showed that weed control and drainage were the best management practices to improve yields(45.6 and 35.3%, respectively), and other practices improved yields by 17.1–21.6%. Consequently, to narrow the yield gap over the short term, the study could focus on techniques that are easily implemented to farmers.
