传统中药一直在我国各种疾病的防治中发挥重要作用,尤其是面对一些较严重的传染病时,相关机构充分发挥传统医学的优势,积极推动中药应用,并充分证明了它的有效性和安全性.猪支原体肺炎是猪常见的一种慢性、接触性呼吸道传染病,在世界范围内广泛流行,给世界养猪行业带来了巨大的经济损失,它的诸多症状与人类呼吸道传染病有诸多相似之处.通过总结人类呼吸道传染病和猪支原体肺炎的相似性以及中药在人类呼吸道传染病的应用,分析目前抗猪肺炎支原体感染的防控措施及存在的主要问题,探讨其对防治猪支原体肺炎的启示,为猪支原体肺炎的防控研究提供思路和参考.

Efficient inactivation of bacteria in the sewage via a photocatalytic process represents a promising strategy for the efficient chemical utilization of solar energy. Herein, uniformly dispersed Fe atoms were embedded between layers of g-C3N4 photocatalysts (CNFx), which were facilely prepared by thermal treatment. The optimized photocatalyst (CNF100) first showed excellent photoactivity for killing a variety of bacteria (93.0% for E. coli, 93.9% for Salmonella, and 96.2% for S. aureus) under visible light irradiation. The superior activity can be attributed to the formation of shallow electron traps (Fe-N3) that can capture excitons of excited states, which promote the charge transfer and energy transfer process of activated adsorbed molecular oxygen, respectively, forming reactive oxygen species, improving separation efficiency of photoexcited electrons and holes, and the Fe-N3 traps can also be used as photosensitive sites to broaden the absorption range of visible light. This strategy of constructing shallow electronic traps lays a theoretical foundation for the design of new environmentally friendly and efficient water disinfectants.

Mesomycoplasma hyopneumoniae is a specific pathogen of pigs that is the etiological agent of mycoplasmal pneumonia of swine (MPS), which is responsible for substantial economic losses to the swine industry worldwide. The pathogenicity mechanism and possible particular virulence determinants of M. hyopneumoniae are not yet completely elucidated.

血管生成素样蛋白(Angiopoietin-like proteins,ANGPTLs)是一类新型的分泌性糖蛋白。近年来,ANGPTLs在畜牧兽医学科上的研究取得了较大的进展,国内外学者已在猪、牛、羊和鸡上开展了初步的研究,结果表明,ANGPTLs有望成为畜禽疾病防治和畜禽品质改善等的新标靶。
