In this study, based on the simulated discharge results of chemical disinfectants, hypocotyl germination concentration gradient pre-test and concentration gradient determination experiment were set up respectively. Laboratory cultivation was conducted to compare and analyze the root germination and germination indexes, three mangrove hypocotyls of Kandelia candel (Linn.) Druce, Ceriopstagal C.B. Rob. and Bruguiera sexangula var. Rhynchopetalas’ efficiency of cumulative root germination, cumulative germination and the cumulative expansion of the second pair of leaves, one-way analysis of variance was used to obtain the tolerance threshold of three mangrove hypocotyls to strong chlorin disinfectant. The study determined that the by-products of strong chlorin disinfectant, the toxic threshold concentrations of Kandelia candel (Linn.) Druce, Ceriopstagal C.B. Rob. and Bruguiera sexangula var. rhynchopetala are close to 0.55 mg/L, 0.55 mg/L and 0.25 mg/L, respectively. This concentration range is lower than the average concentration of 1.183 mg/L of active chlorine emitted from strong chlorine concentrate during pond clearing in high-level shrimp ponds, indicating that transient emissions of strong chlorine concentrate during pond clearing can have a toxic effect on mangrove plants. The strength of tolerance of the embryonic axes of the three mangrove species to effective chlorine contamination was, Ceriopstagal C.B. Rob. stronger than Bruguiera sexangula var. rhynchopetala, and Kandelia candel (Linn.) Druce is the weakest.

肠源性IgA^(+)浆细胞是肠道黏膜免疫发挥免疫效应的关键。肠源性IgA^(+)浆细胞的产生受肠道菌群和饮食调控,不仅在肠道黏膜局部发挥免疫作用,还可迁徙至肠道外的组织或器官,通过依赖产生IgA抗体或分泌细胞因子等非抗体产生效应来调节免疫和炎症反应,在多种疾病中发挥免疫调节的保护或者致病效应。肠道黏膜免疫失衡在IgA肾病中的致病效应逐渐被关注。IgA肾病高血清IgA小鼠肠道固有层IgA^(+)浆细胞的增多与循环中异常糖基化IgA1增多有关。IgA肾病患者循环中的长寿命浆细胞数量增加,并抑制白细胞介素-6发挥致病作用。但肠源性IgA^(+)浆细胞是否迁移至肾脏局部促进疾病进展尚不清楚。现就肠源性IgA^(+)浆细胞在IgA肾病肠道黏膜免疫致病效应及机制的相关研究进展进行综述。

互动仪式链是由无数发生于特定场域中的互动仪式联结构成的链状结构。美国学者柯林斯认为,情境、情感和符号是互动仪式链生成的三重要素。受到传统单一理论灌输的教学模式影响,当前高校思政课教学存在着教学情境构建错位、师生情感传递不足及群体符号设置缺失等主要问题。基于互动仪式链理论探索创新高校思政课教学的路径,需要创设适合学生身心发展的教学情境,传递思想政治教育蕴含的情感,引导学生将课堂中短暂的情绪体验转变为持久的情感能量并内化为群体符号,形成对集体、社会、国家的价值认同,以提升高校思政课的价值引领力。

Carbon dots (CDs) have attracted considerable attention as a new type of fluorescent carbon nanomaterial because of their excellent optical properties, biocompatibility, and high electrical conductivity. Research on CDs has been conducted for nearly two decades and has focused on numerous precursors, various synthesis conditions and properties and applications of CDs. Biomass is critical in the green development of CDs because of its low cost, environmental friendliness, and sustainable properties. This review focuses on the advantages and applications of biomass-derived CDs. In addition, the challenges of photobleaching, toxicity, and stability of biomass-based CDs are discussed in detail. Lastly, the prospects and challenges of biomass-derived CDs are highlighted.
