Background: The aim of this review was to comprehensively summarize and analyze the current guidelines on home-based traditional Chinese medicine (TCM) nursing interventions for discharged patients with COVID-19. Methods: Eight data sources were searched until June 28, 2020. The frequency of home-based TCM nursing interventions and the use of specific acupuncture points recommended in Chinese guidelines for discharged COVID-19 patients were computed and analyzed. Results: In total, we identified 5 Chinese guidelines that provide for home-based TCM nursing interventions for discharged patients with COVID-19. Moxibustion and acupressure were singled out as the most frequently used intervention of the 11 home-based TCM nursing interventions recommended by these guidelines. RN12 and ST36 were the 2 most promoted acupuncture points for moxibustion and acupressure interventions for these patients. Conclusions: The present review showed the important role of home-based TCM nursing interventions for discharged COVID-19 patients. However, direct evidence of their efficacy is still insufficient.

Frequent urban rainstorm inundations can cause serious damages to human life and social economy. Reliable simulation of urban rainstorm inundation is an effective approach for performing flood risk analysis to reduce losses. In this work, a full 2D high-performance hydrodynamic model for urban rainstorm inundation simulation based on Graphic Processing Unit (GPU) was developed. The idealized V-shape catchment and sponge city district of Fengxi New City were selected as the study areas to assess performance of the model. The model was validated against analytical benchmark results of the idealized V-catchment test which show good agreement between the modelled flow and analytical solutions. The model was then applied to simulate actual urban rainstorm inundation process under measured rainfall. The results indicated that the model can be applied to high-resolution urban region simulations. Specifically, the validation results indicated that the proposed model had a good performance, with an accepted error of less than 15%. When applied to compute the Fengxi New city under design rainstorms with different annual return periods of 1, 5, 10, 20, 50, and 100 years, it was found that the model effectively evaluated the temporal and spatial variation process of urban inundation, and quantitatively investigated flood risks according to the water depth change. The model has been substantially accelerated on GPU to quickly predict urbaninundation. The accuracy and rapid simulation speed of the model were verified based on the actual study area. Therefore, the proposed model can help to predict the dynamic processes of urban flood inundation and thus reduce flood inundation disasters. This is essential for future optimal sponge urban construction planning in China.

De novo transcriptome analysis and antimicrobial peptides screening in skin of Paa boulengeri
Yusong Jiang,Wenqiao Fan,Jingming Xu 한국유전학회 2017 Genes & Genomics Vol.39 No.6
Secretion of amphibian skins contain bioactive peptides that considered being an enormous medicine resource pending further exploitation and utilization. In this study, we found the skin secretion of Paa boulengeri exhibited stronger bacteriostatic activity when compared to H. guentheri, R. nigromaculata, and R. chensinensis, particularly against Bacillus subtilis. To discover antibacterial related genes in P. boulengeri, the cDNA library of P. boulengeri skin was constructed and subjected to RNA sequencing analysis. The assembly of the Illumina datasets was optimized using various assembly programs and parameters. The final optimized assembly generated 94,108 transcripts with an average length of 1292 bp and N50 of 2257 bp, representing 121.6 Mb of the P. boulengeri transcriptome. Among the 94,108 transcripts, 38,584 (40.1%) transcripts were annotated and 29,260 (31.1%) were matched with unique protein accessions in the Nr database. A total of 3165 potential cDNA-derived simple sequence repeats were identified, which distributed among 3034 transcripts. In addition, 177 antibacterial peptides and nine different Toll-like receptors were identified in P. boulengeri skin based on this transcriptome dataset. Moreover, some AMPs exhibited high expressions in P. boulengeri, such as Japonicin, which reflects mutual evolution between P. boulengeri and environment. These results provide a comprehensive sequence resource and molecular basis for researches on functional genomics and pharmacological activities of P. boulengeri.

Investigation on Texture, Magnetic Properties and Inhomogeneities of Hot Deformed Nd–Fe–B Magnet
Hongjian Li,Qiong Wu,Ming Yue,Xiaochang Xu,Yuqing Li,Jingming Liang,Wang Xi,Jiuxing Zhang 한국자기학회 2018 Journal of Magnetics Vol.23 No.3
The anisotropic hot deformed nanocyrstalline Nd.Fe.B magnet was prepared by spark plasma sintering technique using MQU-F powders. The location dependence along radial direction on the magnetic properties, microstructure and crystal alignment of the hot deformed magnet have been investigated. The inhomogeneity of the magnetic performance along radial direction was revealed with a vibrating sample magnetometer (VSM). The crystal structure and microstructure were characterized by X-ray diffractometry (XRD) and scanning electron microscopy (SEM), respectively. In addition, quantitative texture analysis was carried out based on the electron backscattered diffraction technique (EBSD). The experimental results reveal that the coordination of grain size and orientation of Nd.Fe.B grains leads to the inhomogeneities of magnetic performance.
