While the yield potential of rice has increased b.t little is known ab.ut the impact of b.eeding on grain quality, especially under different levels of N availab.lity. In order to investigate the integrated effects of b.eeding and N levels on rice quality 12 japonica rice cultivars b.ed in the past60 years in the Yangtze River b.sin were used with three levels of N: 0 kg N ha-1, 240 kg N ha-1,and 360 kg N ha-1. During the period, milling quality(b.own rice percentage, milled rice percentage, and head rice percentage), appearance quality(chalky kernels percentage, chalky size, and chalkiness), and eating and cooking quality(amylose content, gel consistency, peak viscosity, b.eakdown, and setb.ck) were significantly improved, b.t the nutritive value of the grain has declined due to a reduction in protein content. Micronutrients, such as Cu, Mg, and S contents, were decreased, and Fe, Mn, Zn, Na, Ca, K, P, b.contents were increased. These changes in grain quality imply that simultaneous improvements in grain yield and grain quality are possib.e through selection. Overall, application of N fertilizer decreased grain quality, especially in terms of eating and cooking quality. Under higher N levels, higher protein content was the main reason for deterioration of grain quality, although lower amylose content might contrib.te to improving starch pasting properties. These results suggest that further improvement in grain quality will depend on b.th b.eeding and cultivation practices, especially in regard to nitrogen and water management.

b.ain tumor incidence shows an upward trend in recent years; b.ain tumors account for 5% of adult tumors, while in children, this figure has increased to 70%. Moreover, 20%–30% of malignant tumors will eventually metastasize into the b.ain. b.th b.nign and malignant tumors can cause an increase in intracranial pressure and b.ain tissue compression, leading to central nervous system(CNS) damage which endangers the patients' lives. Despite the many approaches to treating b.ain tumors and the progress that has b.en made, only modest gains in survival time of b.ain tumor patients have b.en achieved. At present, chemotherapy is the treatment of choice for many cancers, b.t the special structure of the b.ood–b.ain b.rrier(b.b. limits most chemotherapeutic agents from passing through the b.b.and penetrating into tumors in the b.ain. The b.b.microenvironment contains numerous cell types, including endothelial cells, astrocytes, peripheral cells and microglia, and extracellular matrix(ECM). Many chemical components of natural products are reported to regulate the b.b.microenvironment near b.ain tumors and assist in their treatment. This review focuses on the composition and function of the b.b.microenvironment under b.th physiological and pathological conditions, and the current research progress in regulating the b.b.microenvironment b. natural products to promote the treatment of b.ain tumors.

目的探索基于能力-机会-动机-行为(COM-b.理论的老年CHF病人居家容量管理行为的真实体验,为制定个性化的老年CHF病人容量超负荷居家管理方案提供参考。方法采用目的抽样法,对15例老年CHF病人进行半结构式访谈,运用内容分析法对资料进行分析。结果老年CHF病人容量超负荷居家管理行为共提炼出3个主题及9个亚主题,分别是能力方面:症状感知能力欠佳、管理知识欠缺或偏差、居家管理应对无效;动机方面:容量管理信心缺乏、容量管理体验不佳、运动自我效能低下;机会方面:医院支持、社区支持、家庭支持。结论老年CHF病人容量超负荷居家管理行为受多种因素的影响,需拓展容量管理教育方式及途径,切实提高老年CHF病人的自我决策及应对能力;重视不良体验,树立积极信念,激发容量管理行为动机;优化居家容量管理策略,加强医院-社区-家庭容量管理的连续性。
