| 2 | Novel metabolic and physiological functions of branched chain amino acids: a review显示文摘It is widely known that branched chain amino acids(BCAA) are not only elementary components for building muscle tissue but also participate in increasing protein synthesis in animals and humans. BCAA(isoleucine, leucine and valine) regulate many key signaling pathways, the most classic of which is the activation of the m TOR signaling pathway. This signaling pathway connects many diverse physiological and metabolic roles. Recent years have witnessed many striking developments in determining the novel functions of BCAA including:(1) Insufficient or excessive levels of BCAA in the diet enhances lipolysis.(2) BCAA, especially isoleucine, play a major role in enhancing glucose consumption and utilization by up-regulating intestinal and muscular glucose transporters.(3)Supplementation of leucine in the diet enhances meat quality in finishing pigs.(4) BCAA are beneficial for mammary health, milk quality and embryo growth.(5) BCAA enhance intestinal development, intestinal amino acid transportation and mucin production.(6) BCAA participate in up-regulating innate and adaptive immune responses.In addition, abnormally elevated BCAA levels in the blood(decreased BCAA catabolism) are a good biomarker for the early detection of obesity, diabetes and other metabolic diseases. This review will provide some insights into these novel metabolic and physiological functions of BCAA. | Shihai Zhang Xiangfang Zeng Man Ren Xiangbing Mao Shiyan Qiao | 2017 | Journal of Animal Science and Biotechnology2017,8,3: | 28 |
| 3 | Large and meso-α scale characteristics of intense rainfall in the mid- and lower reaches of the Yangtze River显示文摘Meteorological conditions associated with intense rainfall and great floods over mid- and lower reaches of Yangtze River are studied by analyzing the large-, synoptic-and meso-a-scale circulation systems for 1991, 1996 and 1998. It is found that the advance and retreat of subtropical high over the West Pacific, the monsoon moisture surge from the South China Sea, cold air outbreak over mid- and high-latitudes, and the meso-α scale systems (250-2500 km) from the Tibetan Pleateau as well, are responsible for intense rainfall over the Yangtze River Valley. The persistent and heavy rains and great floods over the Yangtze River Valley occurred when all these four systems are synergetic or in phase lock. | Shunli Zhang Shiyan Tao Qingyun Zhang Jie Wei | 2002 | Chinese Science Bulletin2002,47,9: | 22 |
| 4 | Features of the EAP events on the medium-range evolution process and the mid-and high-latitude Rossby wave activities during the Meiyu period显示文摘In this paper,features for the evolution of the East Asia/Pacific(EAP) events and their association with high-and mid-latitude Rossby waves during the Meiyu period are analyzed on the medium-range time scale.It is shown that life cycles of the positive and negative EAP events cannot be simply regarded as 'mirror' each other.In the upper troposphere,downward propagations of Rossby wave packets both over high-and mid-latitude regions of Eurasian continent and over the Asian jet region are responsible for generating basic patterns of high-and mid-latitude anomaly centers of the events.In this layer,Rossby wave packets also propagate from the mid-latitude anomaly center to the high-latitude one.In the middle and lower troposphere,the formation of the subtropical anomaly center of the event is mainly attributed to the anomalous convective activity in the tropical Pacific warm pool.The northward Rossby wave energy dispersion from this center is favorable to the enhancement and maintenance of the mid-latitude anomaly center in the same layer.Finally,it might be hypothesized that typical features of the positive and negative EAP events in their mature phase result from the interaction between(or phase-locking of) respective anomalous circulations induced both by quasi-zonal Rossby wave packets embedded in upper troposphere westerly and by quasi-meridional Rossby wave packets in the background flow of the East Asian summer monsoon in the middle and lower troposphere. | BUEH Cholaw SHI Ning JI LiRen WEI Jie TAO ShiYan | 2008 | Chinese Science Bulletin2008,53,4: | 23 |
| 5 | Advances in low-protein diets for swine显示文摘Recent years have witnessed the great advantages of reducing dietary crude protein(CP) with free amino acids(AA)supplementation for sustainable swine industry, including saving protein ingredients, reducing nitrogen excretion, feed costs and the risk of gut disorders without impairing growth performance compared to traditional diets. However, a tendency toward increased fatness is a matter of concern when pigs are fed low-protein(LP) diets. In response, the use of the net energy system and balanced AA for formulation of LP diets has been proposed as a solution. Moreover, the extent to which dietary CP can be reduced is complicated. Meanwhile, the requirements for the first five limiting AA(lysine, threonine, sulfur-containing AA, tryptophan, and valine) that growing-finishing pigs fed LP diets were higher than pigs fed traditional diets, because the need for nitrogen for endogenous synthesis of non-essential AA to support protein synthesis may be increased when dietary CP is lowered. Overall, to address these concerns and give a better understanding of this nutritional strategy, this paper reviews recent advances in the study of LP diets for swine and provides some insights into future research directions. | Yuming Wang Junyan Zhou Gang Wang Shuang Cai Xiangfang Zeng Shiyan Qiao | 2018 | Journal of Animal Science and Biotechnology2018,9,4: | 23 |
| 6 | Study and use of the probiotic Lactobacillus reuteri in pigs:a review显示文摘Probiotics are living microorganisms that provide a wide variety of health benefits to the host when ingested in adequate amounts.The bacterial strains most frequently used as probiotic agents are lactic acid bacteria,such as Lactobacillus reuteri,which is one of the few endogenous Lactobacillus species found in the gastrointestinal tract of vertebrates,including humans,rats,pigs and chickens.L reuteri is one of the most well documented probiotic species and has been widely utilized as a probiotic in humans and animals for many years.Initially,L reuteri was used in humans to reduce the incidence and the severity of diarrhea,prevent colic and necrotic enterocolitis,and maintain a functional mucosal barrier.As interest in alternatives to in-feed antibiotics has grown in recent years,some evidence has emerged that probiotics may promote growth,improve the efficiency of feed utilization,prevent diarrhea,and regulate the immune system in pigs.In this review,the characteristics of L reuteri are described,in order to update the evidence on the efficacy of using L.reuteri in pigs. | Chengli Hou Xiangfang Zeng Fengjuan Yang Hong Liu Shiyan Qiao | 2016 | Journal of Animal Science and Biotechnology2016,7,1: | 19 |
| 7 | Advances in research on solid-state fermented feed and its utilization:The pioneer of private customization for intestinal microorganisms显示文摘With sustainable development of biotechnology,increasing attention has been placed on utilization of solid-state fermented feed(SFF).Solid-state fermented feed has been a candidate strategy to alleviate the contradiction between supply and demand of feed resources,ensure food hygiene safety,promoting energy conservation,and emission reduction.In production of SFF,a variety of organic acids,enzymes,vitamins,peptides,and other unknown growth factors are produced,which could affect performance of animals.Solid-state fermented feed produced by different fermentation techniques has great instability on different physiological stages of different animals,which hinders the application and standardized production of SFF.Herein,we summarize the current advances in the role of the characteristics of SFF prepared by different manufacturing technique and its research progress in animal experiments on growth performance,gastrointestinal ecology,and immune system,so as to provide references for further acquiring a relatively perfect set of SFF production and evaluation systems. | Lijie Yang Xiangfang Zeng Shiyan Qiao | 2021 | Animal Nutrition2021,,4: | 14 |
| 8 | Studies on Reducing Nitrogen Excretion: Ⅰ. Net Energy Requirement of Finishing Pigs Maximizing Performance and Carcass Quality Fed Low Crude Protein Diets Supplemented with Crystalline Amino Acids显示文摘Two experiments were conducted to investigate the effects of net energy (NE) level on the performance and carcass traits of finishing pigs fed low crude protein (CP) diets supplemented with crystalline amino acids (CAA). A total of 216 (Exp.1) and 360 (Exp.2) barrows (Yorkshire×Landrace×Duroc) were allotted to one of six treatments (n=6). The experimental diets were based on corn and soybean meal, and consisted of a highCP diet that contained approximately 16% CP and 2.50 Mcal/kg of NE as well as five lowCP diets in which the CP level of the diet was reduced by approximately four percentage units but was supplemented with crystalline lysine, methionine, threonine, and tryptophan. The low CP diets provided 2.64, 2.58, 2.50, 2.42, or 2.36 Mcal/kg in Exp.1 as well as 2.45, 2.40, 2.35, 2.30, or 2.25 Mcal/kg in Exp.2. In Exp.1, a linear (P=0.03) increase in weight gain was observed with decreasing NE level while the ratio of gain to feed was unaffected (P>0.05) by NE level. There was a linear increase (P=0.01) in the percentage of fatfree lean and a linear decrease (P=0.03) in the percentage of total fat with decreasing NE levels. In Exp.2, a significant quadratic (P=0.03) effect of NE level was observed for weight gain. The ratio of gain to feed demonstrated a significant (P<0.01) quadratic effect with pigs fed 2.35 and 2.40 Mcal/kg of NE. Pigs fed the diet containing 2.40 Mcal/kg of NE had the lowest percentage of total fat (36.95%) and the highest percentage of fatfree lean (49.36%). The overall results of these experiments indicate that feeding either a surplus or a deficiency of NE is detrimental to both pig performance and carcass composition when low CP diets supplemented with CAA are fed. Our results indicate that when the CP content of the diet is reduced by four percentage units and the diet is properly supplemented with CAA, maximum performance and carcass quality will be obtained if the diet provides approximately 2.42 Mcal/kg of NE. | Hongyu Chen Xuewu Yi Guijie Zhang Ning Lu Licui Chu P.

| 9 | Dietary modulation of endogenous host defense peptide synthesis as an alternative approach to in-feed antibiotics显示文摘Traditionally, antibiotics are included in animal feed at subtherapeutic levels for growth promotion and disease prevention.However, recent links between in-feed antibiotics and a rise in antibiotic-resistant pathogens have led to a ban of all antibiotics in livestock production by the European Union in January 2006 and a removal of medically important antibiotics in animal feeds in the United States in January 2017.An urgent need arises for antibiotic alternatives capable of maintaining animal health and productivity without triggering antimicrobial resistance.Host defense peptides(HDP) are a critical component of the animal innate immune system with direct antimicrobial and immunomodulatory activities.While in-feed supplementation of recombinant or synthetic HDP appears to be effective in maintaining animal performance and alleviating clinical symptoms in the context of disease, dietary modulation of the synthesis of endogenous host defense peptides has emerged as a cost-effective,antibiotic-alternative approach to disease control and prevention.Several different classes of smallmolecule compounds have been found capable of promoting HDP synthesis.Among the most efficacious compounds are butyrate and vitamin D.Moreover, butyrate and vitamin D synergize with each other in enhancing HDP synthesis.This review will focus on the regulation of HDP synthesis by butyrate and vitamin D in humans, chickens, pigs, and cattle and argue for potential application of HDP-inducing compounds in antibiotic-free livestock production. | Kelsy Robinson Xi Ma Yulan Liu Shiyan Qiao Yongqing Hou Guolong Zhang | 2018 | Animal Nutrition2018,,2: | 9 |
| 10 | Active harmonic suppression of paralleled 12-pulse rectifier at DC side显示文摘In order to improve the ability of harmonic suppression,and reduce the loss of switching devices,this paper proposes an active harmonic suppression method at dc side of multi-pulse rectifier(MPR) . The circulating current through secondary winding of active inter-phase reactor(AIPR) is derived from the current relation between the ac and dc sides of MPR when the threephase input currents are sinusoidal simultaneously,and an applicable circulating current is presented. According to the relation between voltage across secondary winding of AIPR and the applicable current,it is confirmed that harmonic energy of input line current can be consumed by the resistor in series with the secondary winding. A half-bridge PWM rectifier is designed to abstract the harmonic power and to feed the load,which can realize the recycling of harmonic energy. Experimental results show that the power factor of the proposed system is approximately equal to one when the PWM rectifier operates normally,and that the proposed system has the ability of anti-variation of load and input voltage. | MENG FanGang YANG Wei YANG SHiYan | 2011 | Science China(Technological Sciences)2011,54,12: | 8 |
| 11 | Zonal propagation of kinetic energy and convection in the South China Sea and Indian monsoon regions in boreal summer显示文摘Zonal propagation of kinetic energy (KE) and convection in the South China Sea (SCS) and Indian summer monsoon areas are examined in present study. Results suggest that the SCS and Indian summer monsoon prevailed regions (5 —15°N) are dominated by the southwesterly wind, however, the disturbances of KE at 850 hPa and convection are observed mainly coming from the western Pacific Ocean (140—150°E), after passing through the SCS, and westward propagated into the Bay of Bengal (90—100°E). In the Indian summer monsoon domain, where the disturbances of KE are found mainly coming from the Arabian Sea (AS) and eastward propagated into the Bay of Bengal. Therefore, the SCS and the Indian summer mon- soon are quite different in zonal propagation of KE and convection. The SCS summer monsoon is mainly affected by the KE and convection coming from the tropical western Pacific. The Indian summer monsoon, however, can be partly influenced by the AS and the SCS summer monsoon. The analysis also suggests that the interaction region between the SCS and the Indian summer monsoon is around 90—95°E, rather than 105°E as proposed by earlier studies. | CHEN Longxun 1 ,GAO Hui 2 ,HE Jinhai 2 ,TAO Shiyan 3 & JIN Zuhui 3 1.Chinese Academy of Meteorological Sciences,Beijing 100081,China 2.Nanjing Institute of Meteorology,Nanjing 210044,China 3.Institute of Atmospheric Physics,Chinese Academy of Sciences,Beijing 100029,China | 2004 | Science China Earth Sciences2004,47,12: | 7 |
| 12 | High-pressure granulite from Western Kunlun,northwestern China:Its metamorphic evolution,zircon SHRIMP U-Pb ages and tectonic implication显示文摘High-pressure mafic granulites occurring as lenticular bodies within garnet-amphibolites in Kangxiwar Fault have been first reported in this paper. The P-T conditions of two metamorphic stages were ob-tained using calibrated geothermal barometers and ThermoCalc Program. The peak metamorphic con-dition of these high-pressure granulites is about 760―820℃,1.0―1.2 GPa and the retrograde meta-morphic condition is about 620―720℃,0.7―0.8 GPa. The petrological studies show that they have a near-isobaric cooling P-T path which suggests that the Western Kunlun underwent initial crustal thickening,subsequent exhumation and cooling. The SHRIMP zircon U-Pb dating gives two groups of ages for high-pressure granulites. One is 177±6 Ma which is obtained from the rim of the zircon. We consider this age should be the metamorphic age. And the other is 456±30 Ma which is obtained from the core of the zircon and should be the protolith age. The formation of these high-pressure granulites in western Kunlun is closely correlated with the evolution of the Paleo-Tethys and has important im-plications for the research on Tethys and Paleo-Asian tectonic zone. | QU JunFeng ZHANG LiFei AI YongLiang L Zeng WANG JianPing ZHOU Hui WANG ShiYan | 2007 | Science China Earth Sciences2007,50,7: | 7 |
| 13 | Reduning injection for fever, rash, and ulcers in children with mild hand, foot, and mouth disease: a randomized controlled clinical study显示文摘OBJECTIVE: To assess the efficacy and safety of Reduning injection for fever, rash, and ulcers in children with mild hand, foot, and mouth disease(HFMD). METHODS: A stratified-block randomized, double-blind, parallel-controlled, and multicenter clinical trial was conducted with 360 patients in five hospitals across China: Quanzhou Children's Hospital, Shijiazhuang No. 5 Hospital, Shanghai Public Health Centre, Hunan Provincial Children's Hospital, and Kaifeng Children's Hospital. Patients were randomized into three groups with 120 in each. Group A was treated with Western Medicine, group B with Reduning injection, a Chinese herbal medicine, and group C with both Reduning injection and Western Medicine. Results were compared for treatment efficacy and safety on HFMD. The clinical outcomes were observed as follows: fever and onset time of antifebrile effect(time to bring the body temperature down ≥0.5℃ after medication); cumulative time for fever recovery(body temperature recovering to normal and lasting more than 24 h without medication); cumulative time for rash disappearance(without new rashes or ulcers appearing and the original ones fading away); and cumulative time for mouth ulcer disappearance. RESULTS: For the onset time of the antifebrile effect, there was no statistical difference between groups A and B(P>0.05) and groups B and C(P> 0.05). However, there was a statistical difference between groups A and C(P<0.05), and the effect in group C was the best. For the cumulative time for rash disappearance, there was no statistical difference between groups A and B(P>0.05). There were statistical differences between groups A and C, and groups B and C(P<0.05), and the effect in group C was the best. For the cumulative time for mouth ulcers disappearance, there were no statistical differences among the three groups(P>0.05). CONCLUSION: Reduning injection with Western Medicine for symptomatic treatment is most effective for mild HFMD. No adverse reactions were observed. | Guoliang Zhang Jie Zhao Liyun He Shiyan Yan Ziqiang Zhuo Haojie Zheng Yongping Mu Shuangjie Li Xi Zhang Jihan Huang Xiuhui Li Jianping Liu Hehe Wan Chaoyu Wei Wei Xiao | 2013 | Journal of Traditional Chinese Medicine2013,33,6: | 7 |
| 14 | The onset and advance of the Asian summer monsoon显示文摘Based on the daily outgoing longwave radiation (OLR) data from National Oceanic and At- mospheric Administration (NOAA) satellites, the Cli- mate Prediction Center’s merged analysis of pre- cipitation (CMAP) data and the National Centers for Environmental Prediction/National Center for At- mospheric Research (NCEP/NCAR) reanalysis dataset, the mean intraseasonal variability of the Asian summer monsoon (ASM) is investigated by using power spectrum analysis, band-pass filter, and diagnostic analyses. The processes of the onset and advance of monsoon over the southern part of Indo- china Peninsula, the east coast of Bay of Bengal, the South China Sea and the Indian subcontinent are explored. It is found that there is an abrupt change in OLR, precipitation and zonal wind during the onset and advance of the ASM. It is also indicated that the southern part of Indochina Peninsula and the adja- cent Andaman Sea is the region where the earliest onset of the ASM occurs in the 2nd pentad of May. | Lü Junmei ZHANG Qingyun TAO Shiyan JU Jianhua | 2006 | Chinese Science Bulletin2006,51,1: | 7 |

| 16 | Altered Motor-Striatal Plasticity and Cortical Functioning in Patients with Schizophrenia显示文摘Patients with schizophrenia undergo changes in brain plasticity. In the present study, we characterized motor cortical-striatal plasticity in such patients. Compared with the potentiation following high-frequency repetitive transcranial magnetic stimulation in the control group, the patients demonstrated impaired plasticity of corticostriatal motor-evoked potentials recorded from hand muscles.Notably, the loss of cortical plasticity was correlated with impaired motor learning in a rotary pursuit task. Moreover,the loss of plasticity was correlated with the symptoms of schizophrenia. The results suggest that the progression of schizophrenia is accompanied by altered cortical plasticity and functioning. | Dongsheng Zhou Feng Pang Shiyan Liu Ying Shen Lingjiang Liu Zezhong Fang Chuang Wang Zhenyu Hu Ti-Fei Yuan | 2017 | Neuroscience Bulletin2017,33,3: | 5 |
| 17 | Sensitivity of simulated short-range high-temperature weather to land surface schemes by WRF显示文摘The simulations of a heat wave occurring in southern Yangtze-Huaihe valley and southern China during late July,2003 were conducted to examine the sensitivity of simulated surface air temperature(SAT) to different land surface schemes(LSSs) using the Weather Research and Forecasting Model(WRF) Version 2.2 in the short-range mode for 24-h integrations.Initial and boundary conditions employed a National Centers for Environmental Prediction(NCEP) analysis.The results showed that,overall,simulated high-temperature weather is sensitive to different LSSs.Large differences in simulated SAT intensity,threat score,and simulated error under different schemes are identified clearly.In addition,some systematic differences are also in-duced by the LSSs.In terms of threat score from the three LSSs,SLAB is the best,and RUC is better than NOAH.SLAB gives the lowest absolute error for area-averaged SAT,and tends to depict the western Pacific subtropical high with the east-ernmost position at low levels.The LSSs modify the simulated SAT,primarily via the transfer of sensible heat from the land surface to the atmosphere.The physical mechanism of the positive feedback between atmospheric circulation and the SAT is unimportant,with'negative'feedback over most of the simulated areas.This study emphasizes the importance of improving LSSs in SAT forecasting by numerical models. | ZENG XinMin WU ZhiHuang XIONG ShiYan SONG Shuai ZHENG YiQun LIU HuaQiang | 2011 | Science China Earth Sciences2011,54,4: | 5 |

| 19 | Xiyanping injection therapy for children with mild hand foot and mouth disease:a randomized controlled trial显示文摘OBJECTIVE: To evaluate the clinical effects of Xiyan-ping injection intervention in pediatric patients with mild hand foot and mouth disease(HFMD).METHODS: A total of 329 patients were stratified and block-randomized for symptomatic treatment of HFMD and assigned to one of the following groups: Western Medicine(group A, n = 103), Xiyanping injection(group B, n = 109), or Xiyanping injection and symptomatic treatment using Western Medicine(group C, n = 117). During the trial, fever,rash, ulcers of the mouth were observed among participants in each group before and after treatment, and conversion rates from mild to severe HFMD were measured.RESULTS: After 3-7 days' treatment, no significant differences in the conversion rates from mild to severe HFMD were observed among the three groups(P > 0.05). There was a significantly low number of patients with the onset time of antifebrile effect,vanished time of hand and foot rashes and cumulative time for the ulcers in the mouth vanished,among the three groups(P < 0.05, P < 0.01). The onset time of antifebrile effect of patients in groups B and C were markedly shorter compared with those in group A(P < 0.05, P < 0.01); there was no statically significant difference observed between groups B and C(P > 0.05). No significant differences were observed in the time for body temperature recovery among the three groups(P > 0.05). There were no significant differences in adverse effects among the three groups(P > 0.05).CONCLUSION: Xiyanping injection together with use of Western Medicine is most effective for symptomatic treatment of mild HFMD. No severe adverse reactions were observed. | Zhang Guoliang He Liyun Tang Liuping Yang Tong Zou Xinying Zhu Qingxiong Yan Shiyan Hou Yong Huang Baoju Zhao Jindong Li Yan Huang Jihan | 2017 | Journal of Traditional Chinese Medicine2017,37,3: | 4 |
| 20 | Magnetism in Mn and Co doped ZnO bulk samples显示文摘Bulk samples with nominal composition Zn0.95Co0.05O and Zn0.92Co0.05Mn0.03O were fabricated by a solid-state reaction method at 600℃.X-ray diffraction experiment showed that the peaks of secondary phase Co3O4 with a cubic structure were visible in both samples,besides the main peaks of wurtzite structure as ZnO.Magnetization measurement indicated that doping Co alone can induce ferromag- netism in ZnO itself,while the introduction of Mn significantly enhances ferromagnetism.However, both samples showed different magnetic behavior at temperatures below 50 K.It was also noted that ferromagnetic coupling interaction was weakened due to the presence of antiferromagnetic Co3O4. | WANG YongQiang YUAN SongLiu SONG YunXing LIU Li TIAN ZhaoMing LI Pai ZHOU YuanMing LI YunLong YIN ShiYan | 2007 | Chinese Science Bulletin2007,52,8: | 4 |
