Objective:Xiaoqinglong decoction (XQL) has been used in traditional Chinese medicine as a prescription for asthma *** explored the effects of XQL on mucus hypersecretion and ciliophagy in the airways of mice in which asthma had been induced by ovalbumin (OVA).Methods:Thirty-six mice were sensitized by OVA injection (i.p.) on day-0 and day-14 and challenged with 1% OVA on day ***,they were divided into three groups:model,carbocysteine and *** day-15 to day-22,the XQL group was administered XQL (10 g/kg,p.o.) 1 hour before each aerosol challenge with *** evaluate the effect of XQL on mucus hypersecretion,AB-PAS staining,measurement of serum levels of interleukin (IL)-13,bronchoalveolar lavage fluid (BALF) analyses,ciliophagy analyses,as well as coexpression of Light Chain 3 (LC3) and acetylated α-tubulin by immunofluorescence staining were ***:Treatment with XQL (10 g/kg) attenuated mucus secretion in the airways,and reduced the positive areas of AB-PAS staining in histopathologic lung tissues (P <.05).IL-13 expression in serum (P <.01),OVA-induced inflammatory changes,and the number of white blood cells (P <.01) in BALF samples were also ***,the effect on mucus secretion was less apparent in the carbocysteine group compared with the XQL *** treatment also improved the cilia length and elicited a substantial reduction in ciliophagy and LC3 expression in the tracheal ***:XQL can attenuate cilia shortening,aid the clearance function of ciliated epithelial cells,and reduce mucus production in an OVA-induced asthma model in *** can inhibit mucus hypersecretion and could be a new type of pharmacotherapy.

Facing the complex variable high-temperature environment, electromagnetic wave（EMW） absorbing materials maintaining high stability and satisfying absorbing properties is essential. This study focused on the synthesis and EMW absorbing performance evaluation of TiN/Fe2N/C composite materials, which were prepared using electrostatic spinning followed by a high-temperature nitridation process. The TiN/Fe2N/C fibers constructed a well-developed conductive network that generates considerable conduction loss. The heterogeneous interfaces between different components generated a significant level of interfacial polarization. Thanks to the synergistic effect of stable dielectric loss and optimized impedance matching, the TiN/Fe2N/C composite materials demonstrated excellent and stable absorption performance across a wide temperature range（293–453 K）. Moreover, TiN/Fe2N/C-15 achieved a minimum reflection loss（RL） of-48.01 dB and an effective absorption bandwidth（EAB） of 3.64 GHz at 2.1 mm and 373 K. This work provides new insights into the development of high-efficiency and stabile EMW absorbing materials under complex variable high-temperature conditions.

“三农”问题是关系国计民生的根本性问题,做好乡镇预报服务是农业农村公共服务的重要内容之一。本文利用2016—2022年张家港国家站和8个区域站的气温资料,依据温度订正法,分析订正各区域站最高、最低气温。结果表明,国家站和区域站的日最高、最低气温差异不大,而极端高温和极端低温具有明显区域性差异。因此,在气温起伏较大的冬、夏两季,可在国家站预报的基础上,对各乡镇的最低、最高气温极值进行一定的修正,从而更好地提高乡镇气温预报的准确性。
