Its outcome is closely related to bacterial pathogenicity and the timeliness and pertinence of antibiotic treatment. Therefore, early diagnosis is of great significance to the prognosis of patients. Sputum examination and culture is the gold standard for the diagnosis of pathogens of severe pneumonia. However, due to the long time of bacterial culture, the early use of antibiotics, the change of bacteria species, mixed infection and other problems, the results of bacterial culture in sputum are often false negative. With the continuous application of new molecular biology techniques in clinical detection, the classification of bacteria and microorganisms has deepened from the identification of phenotypic characteristics to the classification of gene characteristics. Sequencing analysis with 16S rDNA sequencing technology has the characteristics of high sequencing flux, large amount of data obtained, short cycle, and can more comprehensively reflect the species composition of microbial community, real species distribution and abundance information. In this paper, 16S rDNA sequencing technology was used to analyze the bacterial population composition in the sputum of severe pneumonia, and to explore a new method of etiological diagnosis.展开更多

To develop holistic nursing in pediatrics is to develop nursing services for the purpose of satisfying the various clinical needs and psychological nursing of children. It is of great significance to establish holistic nursing concept, provide high quality nursing service for hospitalized children, and take targeted psychological intervention to alleviate their adverse psychological stress, which can improve treatment compliance and clinical efficacy, and shorten the length of hospital stay. In this paper, scientific and effective psychological nursing stress intervention means are used to improve the psychological anti-stress level of hospitalized children, and nursing intervention means are put forward, contribute to the maintenance of children’s mental health and the development of children’s mental health work and also to provide a theoretical basis for the intervention and treatment of children with psychological stress.展开更多

However, the reduced superconducting transition temperature degenerates both operating temperature and saturation efficiency. Herein, the SNSPD(6.5 nm thickness and 50 nm width) based on the amorphous Mo0.8Si0.2 film with a high optical absorption coefficient demonstrates close-to-unity intrinsic detection efficiency for 1550 nm photons from 75 m K to 2.2 K. Further, a high-performance array SNSPD with optimized 90 nm-width wires is also demonstrated. As-fabricated uniform 4-pixel SNSPD exhibits a saturation plateau for the photon counts at 2.2 K,which overcomes the limitation of operation at low temperature(< 1 K) for traditional amorphous SNSPDs.Coupled with superior intrinsic quantum efficiency, highly efficient photon counts, and low dark count ratio, this detector paves a way for achieving high efficiency and superior yield for large array systems.展开更多
