| 1 | Evaluation on Resource Utilization Potential of Typical Agricultural Waste in Southwest China显示文摘To impel resource utilization of agricultural waste,four provinces and cities of southwest China were taken as research objects,to analyze yield change of typical agricultural waste in southwest China during 2010-2016,and resource amounts of typical agricultural crops straw and livestock and poultry waste and their nutrient contents in four provinces and cities of southwest China in 2016 were calculated. The results showed that resource amount of typical agricultural waste in southwest China overall showed a continuously increasing trend with the improvement of agricultural comprehensive productivity. Straw resource amount of agricultural crops was dominant by rice and corn,and they accounted for 61. 61% of total amount in southwest China. Livestock and poultry manure was dominant by cattle and pig excrement,and they accounted for 89. 59% of total in southwest China. Seen from distribution region,the resource amount sequence of typical agricultural waste in southwest China was Sichuan > Yunnan > Guizhou > Chongqing. N,P_2 O_5 and K_2 O in straw resource of typical agricultural crops in southwest China of 2016 were respectively 76. 11 ×10~4,23.36 ×10~4 and 125. 78 × 10~4 t,and total nutrient amount was 22. 53 × 10~5 t. N,P_2 O_5 and K_2 O of livestock and poultry manure resource were respectively 27. 28 × 10~4,12. 87 ×10~4 and 62. 45 × 10~4 t,and total nutrient amount was 10. 26 × 10~5 t. Therefore,resource amount of agricultural waste in southwest China is rich in a long term,and nutrient storage is huge. Its reasonable recycling is favorable for sustainable development of agriculture in southwest China,and has important actual significance for guaranteeing crop yield and decreasing chemical fertilizer use. | Yin Rongxiu Qin Song Wanjg Wenhua Liu Lingling Fan Chengwu Zhou Ruirong Zheng Yuanli Zhang Bangxi | 2018 | Meteorological and Environmental Research2018，9，6： | 1 |

| 3 | Radio-frequency system of the high energy photon source显示文摘Purpose High energy photon source is a 6 GeV diffraction-limited storage ring light source currently under construction in Beijing.A low-frequency fundamental radio-frequency(rf)system of 166.6 MHz was proposed to accommodate the accelerator physics design.Superconducting rf(srf)technologies were chosen for the storage ring rf accompanied by solid-state power amplifiers and digital low-level rf controls.The design of the rf system was completed,and the parameters are frozen.Elucidation of the rf design with key parameters is desired.Methods The requirements from the accelerator physics design will be presented followed by the detailed rf design.The logic behind the choice of key rf parameters is elaborated.The configuration of the entire rf system is presented.Results and conclusions The fundamental srf cavity of 166.6 MHz was designed to accelerate the ultrarelativistic electron beam.Heavy damping of higher-order modes in these cavities is required to avoid the coupled bunch instabilities.An active third harmonic srf of 499.8 MHz was adopted to realize the required rf gymnastics.Normal-conducting 5-cell cavities will be used for the booster rf.Solid-state amplifiers of 2.4 MW in total will be installed at HEPS to drive these cavities in the booster and the storage ring.A digital low-level rf system will be used to regulate rf field inside each cavity with high stabilities.The rf configuration during the commissioning and the operation scenarios are also presented. | Pei Zhang Jin Dai Ziwei Deng Lin Guo Tongming Huang Dongbing Li Jian Li Zhongquan Li Haiying Lin Yuanli Luo Qiang Ma Fanbo Meng Zhenghui Mi Qunyao Wang Haisheng Xu Xinying Zhang Facheng Zhao Hongjuan Zheng | 2023 | Radiation Detection Technology and Methods2023，7，1： | 1 |
| 4 | Synthesis of biodegradable poly (methylparaben/glycine ethyl ester) phosphazene and further research of its degradation in vitro显示文摘Polydichlorophosphazene(PDCP)was synthesized from PCl5 and NH4Cl via a one-pot approach,and then further reacted with glycine ethyl ester and methylparaben via a two-step nucleophilic substitution approach to give poly(methylparaben/glycine ethyl ester)phosphazene(PMGP),which was a kind of mix-substituted biodegradable polymer.NMR and FT-IR were used to characterize its structure.A series of experiments were conducted to study the effects of the ratio of methylparaben to glycine ethyl ester and the experimental conditions to the degradability of PMGP samples.The degradability of PMGP can be adjusted by altering the ratio of methylparaben to glycine ethyl ester easily. | HUANG XiaoBin CHEN KuiYong LI Jing ZHENG YuanLi JIANG JinGui TANG XiaoZhen | 2011 | Science China Chemistry2011，54，3： | 1 |
| 5 | Apigenin ameliorates imiquimod-induced psoriasis in C57BL/6J mice by inactivating STAT3 and NF-κB显示文摘Psoriasis is a chronic autoimmune disease featured by patches on the skin.It is caused by malfunction of immune cells and keratinocytes with inflammation as one of its key features.Apigenin(API)is a natural flavonoid with anti-inflammatory and immunoregulatory properties.Therefore,we speculated that API can ameliorate psoriasis,and determined its effect on the development of psoriasis by using imiquimod(IMQ)-induced psoriasis mouse model.Our results showed that API attenuated IMQ-induced phenotypic changes,such as erythema,scaling and epidermal thickening,and improved splenic hyperplasia.Abnormal differentiation of immune cells was restored in API-treated mice.Mechanistically,we revealed that API is a key regulator of signal transducer activator of transcription 3(STAT3).API regulated immune responses by reducing interleukin-23(IL-23)/STAT3/IL-17A axis.Moreover,it suppressed IMQ-caused cell hyperproliferation by inactivating STAT3 through regulation of extracellular signal-regulated kinase 1/2 and nuclear factor-κB(NF-κB)pathway.Furthermore,API reduced expression of inflammatory cytokines through inactivation of NF-κB.Taken together,our study demonstrates that API can ameliorate psoriasis and may be considered as a strategy for psoriasis treatment. | Xianshe Meng Shihong Zheng Zequn Yin Xuerui Wang Daigang Yang Tingfeng Zou Huaxin Li Yuanli Chen Chenzhong Liao Zhouling Xie Xiaodong Fan Jihong Han Yajun Duan Xiaoxiao Yang | 2024 | Food Science and Human Wellness2024，13，1： | 0 |
