Alzheimer’s disease（AD） is a neurodegenerative disease with a slow onset process and continuous deterioration over time. With the trend of aging, the number of AD patients is increasing. Therefore, how to make an early accurate diagnosis and positive intervention is an urgent problem to be solved. In order to improve the efficiency of computer-aided diagnosis and promote the study of pathophysiological mechanism of diseases, an improved two-dimension dual-path fusion network based on the SE module is proposed. A reduction coefficient module is added to the network to increase the proportion of useful information in images. The weight function of the channel attention module is redesigned to increase the difference between feature maps, and the network is combined with the two-dimensional dual-path network to increase the network emphasis, so as to achieve better classification performance and prevent model overfitting. The ADNI dataset is used to classify AD, EMCI and NC. The experimental results show that the accuracy of the proposed model is improved by 5.59% and 8.11% compared with the VGG and two-dimensional dual-path fusion model, respectively, which verifies the feasibility of the proposed method.

目的 探究儿童保健宣教对儿童生长发育的影响效果.方法 将2020年1月至2020年7月入选的110例实施保健宣教的儿童作为此次研究对象,随机分为对照组和观察组,各55例.对照组采取常规保健方式,观察组采取儿童保健宣教.比较两组儿童营养性疾病发生率和生长发育效果.结果 观察组儿童营养性疾病发生率3.64％,低于对照组16.36％,差异有统计学意义(P<0.05).观察组儿童身高、体重分别为(79.62±1.06)cm、(12.06±0.74)kg,高于对照组(73.16±1.42)cm、(9.42±0.41)kg,观察组患者运动和适应性评分分别为(89.26±1.45)分、(93.15±1.74)分,高于对照组(72.48±1.42)分、(79.17±1.94)分,对比两组数据,P<0.05,有统计学意义.结论 采用儿童保健宣教方式能够有效降低儿童出现营养性疾病,促进儿童生长发育,值得推广.

目的:探讨婴幼儿超声骨密度测定与护理干预.方法:选取本院自2018年2月至2021年2月收治的100例婴幼儿的临床资料并对其进行回顾分析,均给予超声骨密度测定,并比较常规护理干预与综合护理干预的临床效果.结果:干预后,研究组婴幼儿的身高(74.16±8.85)、体重(10.94±1.24)、SOS(2978.94±376.54)均高于对照组(67.15±7.34、8.67±1.11、2886.89±378.45),有显著差异(P<0.05).结论:测定婴幼儿超声骨密度利于早期了解婴幼儿骨骼的发育,通过综合护理干预利于婴幼儿骨密度值的增长,值得临床推广应用.
