| 3 | Rhubarb extract partially improves mucosal integrity in chemotherapy-induced intestinal mucositis显示文摘AIM To investigate the effects of orally gavaged aqueous rhubarb extract(RE) on 5-fluorouracil(5-FU)-induced intestinal mucositis in rats. METHODS Female Dark Agouti rats(n = 8/group) were gavaged daily(1 mL) with water, high-dose RE(HDR; 200 mg/kg) or low-dose RE(LDR; 20mg/kg) for eight days. Intestinal mucositis was induced(day 5) with 5-FU(150 mg/kg) via intraperitoneal injection. Intestinal tissue samples were collected for myeloperoxidase(MPO) activity and histological examination. Xenopus oocytes expressing aquaporin 4 water channels were prepared to examine the effect of aqueous RE on cell volume, indicating a potential mechanism responsible for modulating net fluid absorption and secretion in the gastrointestinal tract. Statistical significance was assumed at P < 0.05 by one-way ANOVA. RESULTS B o d y w e i g h t w a s s i g n i f i c a n t l y r e d u c e d i n r a t s administered 5-FU compared to healthy controls(P < 0.01). Rats administered 5-FU significantly increased intestinal MPO levels(≥ 307%; P < 0.001), compared to healthy controls. However, LDR attenuated this effect in 5-FU treated rats, significantly decreasing ileal MPO activity(by 45%; P < 0.05), as compared to 5-FU controls. 5-FU significantly reduced intestinal mucosal thickness(by ≥ 29% P < 0.001) as compared to healthy controls. LDR significantly increased ileal mucosal thickness in 5-FU treated rats(19%; P < 0.05) relative to 5-FU controls. In xenopus oocytes expressing AQP4 water channels, RE selectively blocked water influx into the cell, induced by a decrease in external osmotic pressure. As water efflux was unaltered by the presence of extracellular RE, the directional flow of water across the epithelial barrier, in the presence of extracellular RE, indicated that RE may alleviate water loss across the epithelial barrier and promote intestinal health in chemotherapy-induced intestinal mucositis.CONCLUSION In summary, low dose RE improves selected parameters of mucosal integrity and reduces ileal inflammation, manifesting from 5-FU-induced intestinal mucositis. | Juliana E Bajic Georgina L Eden Lorrinne S Lampton Ker Y Cheah Kerry A Lymn Jinxin V Pei Andrea J Yool Gordon S Howarth | 2016 | World Journal of Gastroenterology2016，22，37： | 3 |

| 9 | A NEW APPROACH TO HOLISTIC NITROGEN MANAGEMENT IN CHINA显示文摘Since the 1980s,the widespread use of N fertilizer has not only resulted in a strong increase in agricultural productivity but also caused a number of environmental problems,induced by excess reactive N emissions.A range of approaches to improve N management for increased agricultural production together with reduced environmental impacts has been proposed.The 4R principles(right product,right amount,right time and right place)for N fertilizer application have been essential for improving crop productivity and N use efficiency while reducing N losses.For example,site-specific N management(as part of 4R practice)reduced N fertilizer use by 32%and increased yield by 5%in China.However,it has not been enough to overcome the challenge of producing more food with reduced impact on the environment and health.This paper proposes a new framework of food-chainnitrogen-management(FCNM).This involves good N management including the recycling of organic manures,optimized crop and animal production and improved human diets,with the aim of maximizing resource use efficiency and minimizing environmental emissions.FCNM could meet future challenges for food demand,resource sustainability and environmental safety,key issues for green agricultural transformation in China and other countries. | Xuejun LIU Zhenling CUI Tianxiang HAO Lixing YUAN Ying ZHANG Baojing GU Wen XU Hao YING Weifeng ZHANG Tingyu LI Xiaoyuan YAN Keith GOULDING David KANTER Robert HOWARTH Carly STEVENS Jagdish LADHA Qianqian LI Lei LIU Wim DE VRIES Fusuo ZHANG | 2022 | Frontiers of Agricultural Science and Engineering2022，9，3： | 2 |
