通过在辽河三角洲滨海盐碱稻区设置田间小区试验,探明了不同氮肥用量(0~420 kg/hm^(2))和运筹模式(基肥∶蘖肥∶穗肥分别为6∶3∶1与4∶3∶3,以下简称6∶3∶1模式与4∶3∶3模式)对水稻生长发育以及产量品质的影响。通过对水稻分蘖动态调查研究表明,两种氮肥运筹模式下水稻平均茎蘖数均与施氮量呈显著正相关(r^(2)≥0.90),同时,6∶3∶1模式下氮肥用量对水稻平均茎蘖数的影响程度高于4∶3∶3模式。通过分析不同施氮量与产量的相关关系,发现了两者符合线性加平台肥料效应模型,拟合得到6∶3∶1模式与4∶3∶3模式下的最佳施氮量(EONR)分别为216 kg/hm^(2)(210~235 kg/hm^(2))与316 kg/hm^(2)(300~332 kg/hm^(2)),6∶3∶1模式的EONR比4∶3∶3模式高46.3%。通过考查两种氮肥运筹模式下的氮素利用率指标,发现4∶3∶3模式下各处理氮素利用率(37.2%~40.8%)显著高于6∶3∶1模式(29.9%~34.2%)。通过分析稻米营养与食味品质,在兼顾产量的前提下,再次明确了6∶3∶1模式与4∶3∶3模式下适宜氮肥用量分别为300~332与210~235 kg/hm^(2)。综合考虑水稻产量、氮素利用率以及稻米品质3个指标,推荐辽河三角洲滨海盐碱稻区的适宜氮肥施用量为210~235 kg/hm^(2),最宜采用的氮肥运筹模式为4∶3∶3。研究结果可以为辽河三角洲盐碱稻区合理施肥与氮肥高效利用提供切实的技术指导,为该地区水稻产业绿色发展提供理论支撑。

Objective To develop a preliminary subjective evaluation scale for assessing the built environments of China’s Hygienic City Initiative and to evaluate its reliability and *** The initial items of the scale were determined based on a review of policy documents and consultations with experts. The final items of the scale were confirmed through individual interviews with residents combined with the discretetrend method, critical ratio method, correlation coefficient method, and factor analysis method. Then, the dimensions of the scale were determined using exploratory factor analysis(EFA). The Cronbach’s α coefficient, split-half reliability coefficient, and confirmatory factor analysis(CFA) were used to assess the reliability and validity of the *** A scale containing five dimensions with 22 items was established, including urban lifestyle,governance, basic functions, environmental sanitation, and amenities. The Cronbach’s α coefficient of the scale was 0.876, and the split-half reliability coefficient was 0.796. The CFA results indicate that each inspection level was within the standard *** The preliminarily subjective evaluation scale for assessing the built environments of China’s Hygienic City Initiative demonstrates a high level of reliability and validity. Additional empirical studies should be carried out to further verify the value of the scale in terms of practical application.

The dense and erect panicle (EP) genotype conferred by DEP1 has been widely used in the breeding of high-yield Chinese japonica rice ***,the breeding value of the EP genotype has rarely been determined at the plant population ***,the effects of the interaction of EP genotype and the environment at different locations and times on rice yield and its various components were investigated in this *** sets of near-isogenic lines (NILs)of EP and non-EP (NEP) genotypes with Liaojing 5 (LG5) and Akitakomachi (AKI) backgrounds were grown in the field in 2016 and 2017 in Shenyang,China,and Kyoto,*** 2018,these sets were grown only in Kyoto,*** average yields of the EP and NEP genotypes were 6.67 and 6.13 t ha^(-1)for the AKI background,and 6.66 and 6.58 t ha^(-1)for the LG5 background,*** EP genotype positively affected panicle number (PN) and grain number per square meter (GNPM),mostly resulting in a positive effect on harvest index (HI).In contrast,the EP genotype exerted a negative effect on thousand-grain weight (KGW).The ratio of the performance of the EP genotype relative to the NEP genotype in terms of yield and total biomass correlated positively with mean daily solar radiation during a 40-day period around *** results indicate that the effectiveness of the EP genotype depends on the availability of solar radiation,and the effect of this genotype is consistently positive for sink formation,conditional in terms of source capacity,and positive in a high-radiation environment.

Novel SPPESK/PAA composite proton exchange membranes with semi-interpenetrating polymer network （sIPN） structure have been synthesized through the in-situ polymerization of acrylic acid （AA） in the presence of sulfonated poly （phthalazinone ether sulfone ketone）（SPPESK）. The composite membranes were identified by FT-IR analysis. Water uptake of the composite membranes was as high as 89.7% at 90℃, nearly one time higher than that of the corresponding SPPESK membrane.

核苷酸结合寡聚化结构域样受体蛋白3(Nucleotide-binding oligomerization domain-like receptor family pyrin domaincontaining 3,NLRP3)炎症小体是通过识别体内或体外的危险信号来参与炎症反应的蛋白复合体。在中枢神经系统中,NLRP3炎症小体适当活化能够增强固有免疫系统功能,帮助机体抵抗病原体的侵袭以及清除损伤细胞和病理性蛋白;然而,其过度活化则导致炎症因子过量释放,损伤神经元。本文从NLRP3炎症小体的形成和激活过程入手,探讨了小胶质细胞NLRP3炎症小体在不同类型神经炎症疾病中的作用机制,可为相关疾病的致病机制的深入研究及临床防治提供参考和依据。

目的探讨血浆动脉粥样硬化指数(AIP)与妊娠期糖尿病(GDM)及妊娠结局的关系。方法选取2020年10月—2021年5月于安徽医科大学第一附属医院内分泌科行75 g口服葡萄糖耐量试验的妊娠24~28周的435例孕妇,分为GDM组(217例)和正常对照组(NGT组,218例)。记录所有研究对象临床资料,比较两组临床指标和AIP,采用Pearson相关性分析和多因素logistic回归分析进一步分析GDM患者妊娠中期AIP水平与不良妊娠结局的关系。结果与NGT组比较,GDM组年龄、妊娠前体质量、妊娠前体质量指数(BMI)、空腹血糖(FBG)、1 h血糖(1 h BG)、2 h血糖(2 h BG)、空腹胰岛素(FINS)、2 h胰岛素(2 h INS)、空腹C肽(FCP)、1 h C肽(1 h CP)、2 h C肽(2 h CP)、胰岛素抵抗指数(HOMA-IR)、血糖曲线下面积(AUC-G)、胰岛素曲线下面积(AUC-I)、三酰甘油(TG)、AIP升高,胰岛β细胞功能指数(HOMA-β)、胰岛素敏感指数(ISI)、高密度脂蛋白胆固醇(HDL-C)降低,差异均有统计学意义(均P<0.05)。Pearson相关分析结果显示:GDM组AIP与孕周、妊娠前体质量、妊娠前BMI、FBG、2 h BG、FINS、1 h INS、2 h INS、FCP、1 h CP、2 h CP、HOMA-IR、HOMA-β、AUC-G、AUC-I、TG均呈正相关(r=0.141,0.213,0.222,0.221,0.229,0.324,0.136,0.185,0.262,0.135,0.227,0.341,0.172,0.180,0.165,0.886,均P<0.05),与ISI、TC、HDL-C、LDL-C均呈负相关(r=-0.341,-0.212,-0.709,-0.346,均P<0.05)。NGT组中,40例发生不良妊娠结局,发生率为18.35%;GDM组中,45例发生不良妊娠结局,发生率为20.74%。多因素logistic回归分析结果显示:AIP、TG是GDM患者不良妊娠结局的独立危险因素(OR=1.016,2.679,均P<0.05)。结论GDM患者AIP水平较正常糖耐量孕妇升高,且与糖脂代谢、胰岛素抵抗密切相关。GDM患者的不良妊娠结局发生率较高,AIP、TG是GDM患者不良妊娠结局的独立危险因素,可考虑针对上述患者采取相关干预措施,以改善患者的妊娠结局。
