水稻病害一直是影响水稻产量的重要因素之一,为了快速、准确地检测水稻病害,本研究提出了一种基于卷积神经网络的轻量级水稻叶片病害识别模型。首先,从参数量的角度对注意力机制进行改进,得到轻量级注意力机制模块,对水稻叶片病害特征图中的潜在注意力信息进行深度挖掘;其次,使用深度可分离卷积代替部分标准卷积,进一步降低模型的参数量;最后,为了提高模型的泛化能力,让模型学习过程更快、更稳定,采用了自带内部归一化属性的扩展型指数线性单元函数(SELU)与外部组归一化模块相结合的方法。通过在公共数据集中进行验证,本研究构建模型的平均精度最高(0.990 0),模型在参数量和平均单次迭代时间方面也有一定优势,与其他模型相比,具有相对较好的性能。

目的研究肺炎支原体肺炎(MPP)合并气道黏液栓患儿血清可溶性程序性死亡因子配体-2(sPD-L2)和透明质酸受体Layilin(LAYN)的表达及临床意义。方法选取自2018年1月至2022年1月期间收治的184例MPP患儿为MPP组,以同期择期行腹股沟斜疝60例儿童为对照组。根据支气管镜下是否合并气道黏液栓,将MPP组分为单纯MPP组(130例)和MPP合并气道黏液栓组(54例)。酶联免疫吸附实验检测血清sPD-L2、LAYN水平。多因素logistic回归分析影响MPP患儿合并气道黏液栓的危险因素。受试者工作特征(ROC)曲线分析血清sPD-L2、LAYN对MPP合并气道黏液栓的预测价值。结果MPP组血清sPD-L2、LAYN明显高于对照组,差异有统计学意义(均P<0.05)。MPP合并气道黏液栓组患儿发热时间、血清C反应蛋白、胸腔积液、肺不张、累及肺叶≥2个、sPD-L2、LAYN水平高于单纯MPP组,差异有统计学意义(均P<0.05)。MPP合并气道黏液栓患儿血清sPD-L2、LAYN与白细胞、C反应蛋白、中性粒细胞百分比呈显著正相关(均P<0.05)。发热时间、血清sPD-L2、LAYN升高是影响MPP合并气道黏液栓形成的独立危险因素。发热时间、sPD-L2、LAYN联合对MPP合并气道黏液栓预测的ROC曲线下面积为0.893,高于单一指标检测0.820、0.721及0.789,差异有统计学意义(Z=4.302、5.618、4.518,均P<0.001)。结论MPP合并气道黏液栓患儿血清sPD-L2、LAYN水平升高,发热时间、血清sPD-L2、LAYN升高是MPP合并气道黏液栓形成的独立危险因素,三项联合有助于评估MPP合并气道黏液栓。
