吸引参展者接近展台是参展商达成参展目的的关键。现有研究主要从参展商的视角研究如何通过提供更有效的展台、产品和服务来吸引参展者。然而,在实际展会现场,其他参展者的外表、行为以及参展者之间的无接触互动也会影响参展者对展台的选择和接近行为。本文以2021年“淘宝造物节”和2021年上海国际广告印刷包装纸业展览会(简称广印展)两场贸易类展会的355位参展者为调查对象,研究其他参展者感知对焦点参展者展台接近行为的影响,并检验了参展频率的调节作用。研究表明,其他参展者的相似性、外表及恰当行为均会不同程度地影响焦点参展者的展台接近行为。其中,其他参展者的外表对展台形象和展台信任的影响最大。经验丰富的参展者能够快速从其他参展者的外表识别自己感兴趣的展台,而经验欠缺的参展者则需要考虑更多因素,通过复杂且不确定的机制识别自己感兴趣的展台。本文研究结果有助于指导参展商的展台设计、形象维护与观众管理。参展商应吸引相同属性的目标客户参加展会,对参展者的外表和恰当行为进行适当引导。

目的:探讨在5-FU诱导下脱酰基酶Sirtuin 5对小鼠造血干细胞损伤恢复的影响。方法:采用流式细胞术分析SIRT5缺失对小鼠造血干/祖细胞比例,胸腺T细胞的发育情况,外周血和脾脏中T细胞、B细胞和髓系细胞比例的影响。使用5-FU进行化疗损伤诱导,采用流式细胞术分析SIRT5缺失对骨髓造血干/祖细胞比例的影响,同时检测SIRT5缺失小鼠造血干/祖细胞的细胞周期和凋亡。通过流式分选进行造血干细胞体外培养,分析SIRT5缺失对造血干细胞增殖能力的影响。结果:与野生型相比,SIRT5的缺失不影响小鼠胸腺中T细胞的发育以及外周血和脾脏中T细胞、B细胞和髓系细胞比例。在骨髓中,SIRT5缺失小鼠的造血干/祖细胞比例升高。在5-FU处理的造血损伤情况下,SIRT5缺失会导致小鼠造血干细胞比例下降(P<0.05),并且SIRT5缺失小鼠的造血干/祖细胞由G_(0)期向G_(1)期激活(P<0.05),同时伴随早期凋亡率显著升高(P<0.05)。通过体外单克隆培养,与野生型相比,SIRT5缺失小鼠的造血干细胞克隆形成能力显著下降(P<0.05)。结论:SIRT5缺失导致造血干细胞体外克隆能力下降。在造血应激情况下,SIRT5缺失不利于小鼠造血干/祖细胞损伤后的恢复。

作为四大新兴污染物之一的“微塑料”带来的危害日益凸显,微塑料的检测识别是其污染评估和风险管理防控的关键。以鱼粉饲料中的微塑料(包括PA、PE、PET、PP、PS、PVC)作为研究对象,运用XGBoost算法分别研究构建了近红外光谱和红外光谱定性识别模型。采用GridSearchCV工具包研究优化XGBoost模型的主要超参数,近红外光谱模型的超参数优化结果为n_estimators:300,learning_rate:0.08,gamma:0,max_depth:4,min_child_weight:1;红外光谱的超参数优化结果为n_estimators:100,learning_rate:0.02,gamma:0.20,max_depth:4,min_child_weight:1。基于优化后的超参数构建的近红外定性识别模型平均精确率(Precision)为0.985,平均召回率(Recall)为0.977,平均F1值(F1 score)为0.978,相比于优化前模型效果分别提升了40.17%,51.00%,50.00%;红外定性识别模型平均精确率(Precision)、平均召回率(Recall)和平均F1值(F1 score)均为1.000,优化后的模型效果分别提升了20.67%,27.50%,26.33%。进一步与PLS-DA模型对比分析发现,红外光谱的XGBoost模型与PLS-DA模型效果基本一致,近红外光谱的XGBoost模型各参数(Accuracy,Precision,Recall,F1 score)效果均不同程度地优于PLS-DA模型。综上所述,运用XGBoost算法可以有效识别鱼粉中不同种类的微塑料,该研究为鱼粉饲料中微塑料的快速检测识别方法提供理论支持和技术支撑。

目的:评价脱细胞猪角膜基质深板层移植治疗感染性角膜炎的有效性、安全性。方法:前瞻性研究。收集2017-02/2020-10在我院经药物保守治疗无效的感染性角膜炎患者17例17眼,应用脱细胞猪角膜基质进行深板层角膜移植手术。术后随访6 mo,观察BCVA、角膜上皮愈合情况、角膜透明情况,并记录有无感染复发以及植片排斥。结果:所有患者中均顺利完成深板层角膜移植手术,均未发生术中并发症,无失访病例,术后角膜感染均得到有效控制。术后BCVA均较术前改善(P<0.05)。17眼中16眼术后1 mo上皮完全覆盖角膜植片,仅1眼上皮未完全愈合,为病毒性角膜炎的反复发作。术后1.5 mo所有患者上皮均完全愈合。术后1 mo角膜水肿开始改善,其中1眼角膜植片轻度混浊,16眼中重度混浊;术后3-6 mo角膜透明度稳定,至术后6 mo时4眼完全透明,6眼轻度混浊,6眼中度混浊,1眼重度混浊。随访过程中,无感染复发,有1眼发生眼压升高现象,经治疗后眼压恢复正常。结论:脱细胞猪角膜基质深板层移植治疗感染性角膜炎,不仅能有效控制感染,缓解患者角膜刺激症状,恢复角膜的解剖与功能,而且能维持良好的透明性,提高患者视力,可作为替代同种异体人角膜。
