| 1 | Phylogenetic and genetic characterization of a 2017 clinical isolate of H7N9 virus in Guangzhou,China during the fifth epidemic wave显示文摘Pathogenic H7N9 influenza viruses continue to pose a public health concern. The H7N9 virus has caused five outbreak waves of human infections in China since 2013. In the present study, a novel H7N9 strain(A/Guangdong/8 H324/2017) was isolated from a female patient with severe respiratory illness during the fifth wave of the 2017 H7N9 epidemic. Phylogenetic analysis showed that the H7N9 viruses collected during the fifth wave belong to two different lineages: the Pearl River Delta lineage and the Yangtze River Delta lineage. The novel isolate is closely related to the Pearl River Delta H7N9 viruses, which were isolated from patients in Guangdong Province. The novel H7N9 isolate has an insertion of three basic amino acids in the cleavage site of hemagglutinin(HA), which may enhance virulence in poultry. The 2017 isolate also possesses an R292 K substitution in the neuraminidase(NA)protein, which confers oseltamivir resistance. This study highlights the pandemic potential of the novel H7N9 virus in mammals;thus, future characterization and surveillance is warranted. | Yongqiang Deng Chunlin Li Jianfeng Han Yingfen Wen Jian Wang Wenxing Hong Xiaofeng Li Zhongyu Liu Qing Ye Jing Li Changshuai Zhou Lei Yu Chengfeng Qin Fuchun Zhang Tao Jiang | 2017 | Science China(Life Sciences)2017，60，12： | 9 |
| 2 | Effects of magnesium on the performance of sows and their piglets显示文摘The objective of this study was to evaluate the effects of supplemental magnesium(Mg) on the performance of gilts and parity 3 sows and their piglets.Fifty-six gilts(Trial 1) and 56 sows(Trial 2) were assigned to one of 4treatments according to their mating weight,respectively.The treatments comprised corn-soybean meal based gestation and lactation diets(0.21%magnesium) supplemented with 0,0.015,0.03,or 0.045%Mg from mating until weaning.The results showed that magnesium supplementation significantly(P < 0.05) reduced the weaning to estrus interval in both gilts and sows.There were significant effects(P < 0.05) of supplemental magnesium on the total number of piglets born,born alive and weaned in sows.In late gestation and lactation,the digestibility of crude fiber(quadratic effects,P< 0.05),and crude protein(P< 0.05),were significantly influenced by magnesium in gilts and sows,respectively.There were differences among the 4 groups in terms of the apparent digestibility of dry matter and crude fiber in sows(P< 0.05) during both early and late gestation.The apparent digestibility of gross energy was increased for sows in late gestation(P< 0.05),and lactation(quadratic effects,P< 0.05).At farrowing and weaning,serum prolactin levels and alkaline phosphate activities linearly increased in sows as the Mg supplementation increased(P < 0.05).Serum Mg of sows at farrowing and serum urea nitrogen of sows at weaning was significantly influenced by Mg supplementation(P< 0.05).The Mg concentration in sow colostrum and the serum of their piglets were increased by supplemental magnesium(P < 0.05).In addition,growth hormone levels were linearly elevated(P< 0.05) in the serum of piglets suckling sows.Our data demonstrated that supplemental magnesium has the potential to improve the reproduction performance of sows,and the suitable supplemental dose ranged from 0.015%to 0.03%. | Jianjun Zang Jingshu Chen Ji Tian Aina Wang Hong Liu Shengdi Hu Xiangrong Che Yongxi Ma Junjun Wang Chunlin Wang Guanghua Du Xi Ma | 2015 | Journal of Animal Science and Biotechnology2015，6，1： | 3 |

| 4 | Glutamate synthase 1 is involved in iron-deficiency response and long-distance transportation in Arabidopsis显示文摘Iron is an essential microelement for plant growth.After uptake from the soil,iron is chelated by ligands and translocated from roots to shoots for sub-sequent utilization.However,the number of ligands in-volved in iron chelation is unclear.In this study,we identified and demonstrated that GLU1,which encodes a ferredoxin-dependent glutamate synthase,was involved in iron homeostasis.First,the expression of GLU1 was strongly induced by iron deficiency condition.Second,lesion of GLU1 results in reduced transcription of many iron-deficiency-responsive genes in roots and shoots.The mutant plants revealed a decreased iron concentration in the shoots,and displayed severe leaf chlorosis under the condition of Fe limitation,compared to wild-type.Third,the product of GLU1,glutamate,could chelate iron in vivo and promote iron transportation.Last,we also found that supplementation of glutamate in the medium can alleviate cadmium toxicity in plants.Overall,our results provide evidence that GLU1 is involved in iron homeo-stasis through affecting glutamate synthesis under iron deficiency conditions in Arabidopsis. | Man Cui Mengjun Gu Yaru Lu Yue Zhang Chunlin Chen Hong‐Qing Ling Huilan Wu | 2020 | Journal of Integrative Plant Biology2020，62，12： | 2 |
| 5 | Efficacy of Chaihu Jisang decoction on post-infection cough and its effect on cough reflex sensitivity显示文摘OBJECTIVE:To investigate the efficacy of Chaihu Ji Sang Decoction(CJSD),(a modification of Xiao Chaihu Tang(Minor Decoction of Bupleurum) was evaluated in patients with post-infection cough(PIC).Its effect on cough reflex sensitivity(CRS) was also described.METHODS:One hundred and eighteen patients with PIC were enrolled and randomly divided into an experimental group and control group(54 patients in each group).The experimental group was given CJSD orally,and the control group was given cetirizine hydrochloride for 7 d.Cough symptom scores and TCM symptom scores were compared before and after treatment.Efficacy,cough onset time,recurrence,and adverse drug reactions were additionally evaluated.Finally,CRS was evaluated before and after treatment of PIC patients in the experimental group.RESULTS:Fifty-two patients in the experimental group and fifty control patients completed the study.Cough symptom scores and the TCM symptom scores of the two groups were significantly improved after treatment,however cough symptoms in the experimental group 1(0,2) were significantly lower than the control group 2(1,2) after treatment(P < 0.05).Similarly,TCM symptom scores 4(0,7) in the experimental group were significantly lower than the control group 6(3,12)(P < 0.01).Overall,the effective rate of the experimental treatment(84.60%) was significantly higher than that of the control treatment(68.00%)(P < 0.01).The onset time of efficacy of the experimental treatment was one day faster than the control treatment [2(2,3) d vs 3(2,3) d,P < 0.01].The relapse rate in the experimental group(9.09%) was lower than that of the control group(29.41%)(P < 0.05).39 PIC patients in the experimental group completed a capsaicin cough challenge test before treatment.The lgC2 and lg C5 of the experimental group prior to treatment was 1.19(0.59,1.49) and 1.80(1.49,2.10),respectively.The lgC2,lg C5 of the healthy control group was 1.49(0.89,2.40) and 2.70(2.40,3.00),respectively.The differences in lgC2 and lg C5 between experimental group and healthy groups were significant at this time point(both P < 0.01).After treatment,34 patients in the experimental group received re-examination.lg C5 increased from 1.80(1.49,2.10) to 2.10(1.49,3.00).CRS after treatment/re-examination was significantly lower than those of baseline in the experimental group(P < 0.05).CONCLUSION:CJSD could effectively improve the clinical symptoms of PIC patients,with demonstrable low recurrence and safety.CJSD also significantly decreased the CRS in patients with PIC. | Hong Minli Huang Baopei Hong Chunlin Chen Huinuan Chen Wenxi Liu Chaohui Li Xinjian Li Candong | 2018 | Journal of Traditional Chinese Medicine2018，38，4： | 2 |

| 8 | Preparation of Functionalized Graphene Nano-platelets and Use for Adsorption of Pb2+ from Solution显示文摘Functionalized graphene nano-platelets(FGN) were obtained via treating graphene nanoplatelets(GN) with HNO_3, and served as adsorbent for the removal of Pb^(2+) from solutions. We investigated the FGN adsorption capacity for Pb^(2+) at different initial concentrations, varying pH, contact time and temperature. The characterization results of scanning electron microscopy(SEM), thermal analysis(TG/DTG), Fourier transform infrared spectroscopy(FT-IR) and Brunauer-Emmett-Teller(BET) method indicated that FGN layers were thin and possess large specific area with oxygen-containing functional groups grafted onto their surface. Meanwhile, the determined equilibrium adsorption capacity of FGN for Pb^(2+) was 57.765 mg/g and adsorption isotherms well confirmed to Langmuir isotherms models. The results reveals that the FGN has better effect of water treatment. | 盛智博 曹明莉 HONG Yin WANG Shengniang FAN Zhihong XIONG Jianbo YANG Haicheng DENG Chunlin | 2018 | Journal of Wuhan University of Technology(Materials Science)2018，33，6： | 1 |
| 9 | Upper Paleozoic total petroleum system and geological model of natural gas enrichment in Ordos Basin, NW China显示文摘Based on the analysis of Upper Paleozoic source rocks, source-reservoir-caprock assemblage, and gas accumulation characteristics in the Ordos Basin, the gas accumulation geological model of total petroleum system is determined. Then, taking the Carboniferous Benxi Formation and the Permian Taiyuan Formation and Shanxi Formation as examples, the main controlling factors of gas accumulation and enrichment are discussed, and the gas enrichment models of total petroleum system are established. The results show that the source rocks, faults and tight reservoirs and their mutual coupling relations control the distribution and enrichment of gas. Specifically, the distribution and hydrocarbon generation capacity of source rocks control the enrichment degree and distribution range of retained shale gas and tight gas in the source. The coupling between the hydrocarbon generation capacity of source rocks and the physical properties of tight reservoirs controls the distribution and sweet spot development of near-source tight gas in the basin center. The far-source tight gas in the basin margin is mainly controlled by the distribution of faults, and the distribution of inner-source, near-source and far-source gas is adjusted and reformed by faults. Generally, the Upper Paleozoic gas in the Ordos Basin is recognized in four enrichment models: inner-source coalbed gas and shale gas, inner-source tight sandstone gas, near-source tight gas, and far-source fault-transported gas. In the Ordos Basin, inner-source tight gas and near-source tight gas are the current focuses of exploration, and inner-source coalbed gas and shale gas and far-source gas will be important potential targets in the future. | JIANG Fujie JIA Chengzao PANG Xiongqi JIANG Lin ZHANG Chunlin MA Xingzhi QI Zhenguo CHEN Junqing PANG Hong HU Tao CHEN Dongxia | 2023 | Petroleum Exploration and Development2023，50，2： | 1 |
| 10 | Microscopic origin and relevant grain size effect of discontinuous grain growth in BaTiO3-based ferroelectric ceramics显示文摘Barium titanate[BaTiO_(3)(BT)]-based ceramics are typical ferroelectric materials.Here,the discontinuous grain growth(DGG)and relevant grain size effect are deeply studied.An obvious DGG phenomenon is observed in a paradigmatic Zr^(4+)-doped BT-based ceramic,with grains growing from∼2.2–6.6 to∼121.8–198.4μm discontinuously near 1320℃.It is found that fine grains can get together and grow into large ones with liquid phase surrounding them above eutectic temperature.Then the grain boundary density(D g)is quantitatively studied and shows a first-order reciprocal relationship with grain size,and the grain size effect is dependent on D g.Fine grains lead to high D g,and then cause fine domains and pseudocubic-like phase structure because of the interrupted long-range ferroelectric orders by grain boundary.High D g also causes the diffusion phase transition and low Curie dielectric peak due to the distribution of phase transition temperature induced by internal stress.Local domain switching experiments reveal that the polarization orientation is more difficult near the grain boundary,implying that the grain boundary inhibition dominates the process of polarization orientation in fine-grain ceramics,which leads to low polarization but a high coercive field.However,large-grain ceramics exhibit easy domain switching and high&similar ferroelectricity.This work reveals that the grain boundary effect dominates the grain size effect in fine-grain ceramics,and expands current knowledge on DGG and grain size effect in polycrystalline materials. | Hong Li Bo Wu Cong Lin Xiao Wu Tengfei Lin Min Gao Hong Tao Wenjuan Wu Chunlin Zhao | 2023 | Journal of Materials Science & Technology2023，，33： | 0 |
| 11 | Discovery of a Potent Botulinum Neurotoxin A Inhibitor ZM299 with Effective Protections in Botulism Mice显示文摘Botulinum neurotoxins serotype A(BoNT/A)is the deadliest toxins known to humans and the'Category A'agent for bioterrorism.Over the past 20 years,significant efforts have been put forth to develop effective inhibitors of BoNT/A.Unfortunately,few identified inhibitors possess noteworthy efficacy against BoNT/A in vivo.Here,we performed a high-throughput virtual screening based on the structure-based docking simulations and found a novel potent scaffold 2-thionicotinate that inhibits the BoNT/A light chain(LC).We then synthesized and optimized a novel series of 2-thionicotinate derivatives and comprehensively evaluated their activity against BoNT/A in vitro and in vivo.An optimized compound ZM299 effectively exhibits anti-BoNT/A activity in primary neurons and displayed remarkably therapeutic efficacy against BoNT/A in vivo,which could raise the survival rate of intoxicated mice to 100%(12/12)after lethal doses of BoNT/A exposures.These findings demonstrate that 2-thionicotinates is a promising scaffold for producing more effective anti-BoNT/A analogs,and compound ZM299 is worthy of further preclinical evaluation as a drug candidate for the treatment of botulism. | Jianxin Wang Yuelin Wu Deyan Luo Chunlin Zhuang Nianzhi Ning Yanming Zhang Zhili He Jie Gao Zhanying Hong Xiguo Xv Wannian Zhang Tao Li Zhenyuan Miao Hui Wang | 2022 | Chinese Journal of Chemistry2022，40，3： | 0 |
| 12 | Nighttime snacking is associated with risk of obesity and hyperglycemia in adults:a cross-sectional survey from Chinese adult teachers显示文摘Relationship between nighttime snack and human health conditions remains unclear. In this paper, we analyzed the association of frequency of nighttime snacking with obesity, hyperlipidemia and hyperglycemia using a Chinese teacher cohort. The Chinese teacher study contains 22,176 of the general adult population operated on in 2015.Information of nighttime snacking frequency was acquired by questionnaire. Overweight and obesity outcome were assessed by body mass index(BMI), and hypertension; hyperlipidemia and hyperglycemia were self-reported.Associations between nighttime snacking consumption and outcomes were performed with multivariat regression and further stratification analyses. We found a significant association(OR 2.11, 95% CI 1.24, 3.62; P for trend <0.001)between most frequent nighttime snacking and hyperglycemia. A remarkable association was also observed between most frequent consumption of nighttime snack and obesity(OR 3.10, 95% CI 1.63, 5.89; P for trend<0.001). The present results provide epidemiological evidence that consumption of nighttime snack was associated with obesity and hyperglycemia in Chinese adult teachers. However, the underlying mechanisms still need further investigation. | Xiaoyang Liu Chunlin Zheng Cheng Xu Qian Liu Jin Wang Yongzhi Hong Peng Zhao | 2017 | The Journal of Biomedical Research2017，31，6： | 0 |
| 13 | A Ten-Year Reflection on the Events of 9/11 and Their Impact on China显示文摘The 9/11 attack was undoubtedly one of the most important events to influence international relations in the 21st century. On September 11th, 2001, al-Qaeda, led by Osama bin Laden, attacked the US heartlands. The attacks caused the death of nearly 3000 people and led to direct economic losses of around US$ 100 billion. This was the most serious external attack on the US since the War of Independence of 1812. In influence it surpassed even the attack on Pearl Harbor in the Second World War. 9/11 highlighted the importance of non-traditional security and raised it to a position almost parallel with that of the world's traditional security agenda. The events have profoundly influenced the outlook and behavior of the world's | Jin Canrong,the Vice Director and professor of the Institute of International Relations, Renmin University of China.
