Fresh garlic scape is popular for its unique tastes and special antibacterial effect. As a kind of seasonal vegetable, it has huge quality decay after harvesting, and usually by low temperature storage to approach the round‐year supply. However, it lacks cold chain management directions and transparency, which depends heavily on the real‐time information of the process environments and the quality of fresh garlic scapes. With the analyzed quality‐related indicators, including temperature, relative humidity, gas composition and vibration, a multi‐sensors information acquisition system based on wireless sensor network was designed and developed. Then, the process of the fresh garlic scapes supply were systematically analyzed and identified, and the proposed system was also evaluated using the monitored data in current practices. Results show that the transportation and cold storage occupies an important position in the typical garlic scapes supply process, which has continuous influences on the quality preservation. The developed system functions well, and the wireless multi‐sensors nodes can real‐time monitor environmental information with high data reliability. The data evaluation also demonstrates the association of the monitored quality‐related data with the supply process stage. Meanwhile, it is the visualization of the quality‐related data that enhance the real‐time sensing of the quality in storage, the transparency of the supply process and the cold chain management level. Furthermore, the system should be further enhanced with the better data quality acquired by the nodes for better quality sensing and management of the fresh garlic scapes supply process. Practical Applications: Significant benefits of this work are anticipated on the postharvest and preservation of garlic scapes to the market and reduction of its losses in the postharvest chain.

Background: The aim of this study was to investigate the effects of different doses of chicken spleen transfer factor (TF) on the structure of intestinal epithelial cells in different age groups. One-day-old White Leghorns laying hens were randomly divided into four groups: three groups were administered TF at different dosages (0.10, 0.25 or 1.00 mL) and a fourth group was set as control (administered saline, 1.00 mL). Using hematoxylin and eosin staining, high-throughput sequencing, microbiota analysis, quantitative polymerase reaction and western blotting., Results: We measured the effects of different doses of TF on the following: intestinal mucosal epithelial tissue morphology, intestinal mucosal epithelial barrier-related gene expression profiles, and intestinal epithelial tight junction gene protein levels. The collected data show that TF can improve the absorption of nutrients by increasing villus height and crypt depth, and regulate intestinal flora disorders. Furthermore, we verified that the expression of the claudin and occludin tight junctions between intestinal epithelial cells was increased with TF. this research is very important for focusing on the structure and gene expression of intestinal tissues., Conclusion: The results provide a scientific rationale for feeding and nutrition programs for green and healthy farming, as well as technical support to improve the production efficiency of the livestock and poultry breeding industry. © 2022 Society of Chemical Industry., (© 2022 Society of Chemical Industry.)

Objective: To evaluate the degree of recruitment and activation of eosinophils; to confirm the concentration and expression of IL-5 in nasal polyps; to study the correlation between eosinophilic activation and cytokine such as IL-5., Method: Blood and nasal specimens were collected from 30 patients with nasal polyps and 8 controls with deviation of nasal septum or OSAS. The serum ECP levels in two groups and the IL-5 and ECP in nasal polyp specimens or inferior turbinate mucosa were examined., Result: Concentration of IL-5 and ECP in nasal polyps tissue homogenates were significantly higher than those in inferior turbinate mucosas (P < 0.05). The same result was showed in serum ECP. The elevated IL-5 levels in polyp homogenates had a significant correlation with serum ECP(r = 0.598, P < 0.05) and polyp tissues ECP(r = 0.451, P < 0.05)., Conclusion: The concentration of IL-5 increased in the nasal polyp tissues and the degree of expression showed a significant correlation with activated eosinophils.
