目的探讨血清硫氧还蛋白1(TRX-1)、核苷酸结合寡聚化结构域样受体蛋白3(NLRP3)表达水平与儿童功能性消化不良(FD)的相关性。方法选取2022年5月至2023年6月就诊于石家庄市妇幼保健院的FD患儿45例为FD组;另选取健康儿童40例为对照组。采用实时荧光定量PCR测定血清TRX-1、NLRP3 mRNA表达水平,Spearman相关分析血清TRX-1 mRNA、NLRP3 mRNA表达水平与FD相关评分的相关性,多因素Logistic回归分析FD发生的影响因素。结果FD组血清TRX-1 mRNA、NLRP3 mRNA表达水平均高于对照组(P0.05)。血清NLRP3 mRNA表达水平与总分呈正相关(P0.05)。血清TRX-1 mRNA、NLRP3 mRNA水平升高是FD发生的独立危险因素(P<0.05)。结论血清TRX-1、NLRP3表达水平可能在FD的发病过程中发挥着重要作用。

软土地基天然含水率高、抗剪强度低,在其上修筑堤防易出现沉降变形过大、产生裂缝等现象。以杜家台分蓄洪区外围新合堤加固工程为例,除其软土地基外,堤防施工填筑速率和堤顶加载也是出现裂缝的重要要原因。通过对参数复核、修正,再利用反算参数进行方案计算确定最终加固方案进行施工,堤防运行4年后再进行达标加固,截止目前堤防均运行良好,说明采取的设置平台和填塘固基的处理措施对新合堤是合适的。

Layer-by-layer (LbL) strategy has been developed to form bulk heterojunction (BHJ) structure for processing efficient organic solar cells (OSCs). herein, LbL slot-die coating with twin boiling point solvents (TBPS) strategy was developed to fabricate highly efficient OSCs, which matches with large-scale, high throughput roll-to-roll (R2R) industrialized mass process. The TBPS strategy could produce high-quality thin film without any additive, leading to the optimized vertical phase separation with interpenetrating nanostructures, as well as the enhanced charge transport and extraction. Thus, the power conversion efficiency up to 14.42% was achieved for [(2,6-(4,8-bis(5-(2-ethylhexyl-3-fluoro)thiophen-2-yl)-benzo [1,2-b:4,5-b′]dithiophene))-alt-(5,5-(1′,3′-di-2-thienyl-5′,7′-bis(2-ethylhexyl)benzo[1′,2′-c:4′,5′-c′]dithiophene-4,8-dione)]:2,2′-((2Z,2′Z)-((12,13-bis(2-ethylhexyl)-3,9-diundecyl-12,13-dihydro-[1,2,5]thiadiazolo[3,4-e]thieno[2″,3″:4″,5″]thieno[2′,3′:4,5]pyrrolo[3,2-g]thieno[2′,3′:4,5]thieno[3,2-b]indole-2,10-diyl)bis(methanylylidene)) bis(5,6-difluoro-3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile (PM6:Y6) OSCs fabricated via sequentially LbL slot-die coating using the TBPS strategy under ambient condition. The research provides a potential route for industrialized production of high-efficiency and large-area OSC devices.
