| 1 | New U-Pb Geochronological Constraints on Formation and Evolution of the Susong Complex Zone in the Dabie Orogen显示文摘Objective The Susong complex zone(SCZ)is a relatively lowgrade metamorphic unit mostly with an epidoteamphibolite facies,located in the southernmost part of the Dabie orogen.However,its rock compositions,ages,metamorphic processes and petrogenesis are | LI Yuan LIU Yican YANG Yang DENG Liangpeng | 2017 | Acta Geologica Sinica(English Edition)2017，91，5： | 5 |
| 2 | Multistage exhumation and partial melting of high-T ultrahigh-pressure metamorphic rocks in continental subduction-collision zones显示文摘High-temperature(HT, >850℃) metamorphism in continental collision orogens, particularly for those ultrahigh-pressure(UHP) metamorphic rocks, has become one of the remarkable topics in Earth science. It has bearing on the element and isotope behaviors of UHP rocks, their partial melting and related geodynamic effects during exhumation. In this paper, five representative continental collision orogens with typical HT/UHP rocks, including the Dabie orogen in China, the Kokchetav in Kazakhstan, the Caledonides in Greenland, the Rhodope in Greece, and the Erzgebirge in Germany are introduced, and their HT/UHP metamorphism and evolution processes are summarized. In addition, metamorphic P-T-t paths, multistage exhumation processes, and partial melting and preservation and retrogression of UHP index minerals during exhumation and their possible mechanisms are discussed. On this basis, the forthcoming key fields and scientific subjects of HT/UHP rocks within continental subduction channel are proposed. | LIU Yi Can DENG LiangPeng GU XiaoFeng | 2015 | Science China Earth Sciences2015，58，7： | 3 |

| 4 | Characterizing the influence of gut microbiota on host tryptophan metabolism with germ-free pigs显示文摘Intestinal microbes are closely associated with host health,depending on metabolic crosstalk between the microbiota and host.Tryptophan metabolism is one of the best examples of metabolic crosstalk between intestinal microbiota and host;however,our understanding about the influence of intestinal microbiota on host tryptophan metabolism is limited.Thus,we established germ-free(GF)pig models to systemically explore the influence of intestinal microbiota on tryptophan metabolism.Five GF pigs were kept in GF conditions throughout the experiment(GF group).Six GF pigs were transplanted with fecal microbiota from donor sows to act as control pigs.Compared with control pigs,the GF pigs had remarkable alterations in tryptophan metabolism.The differential metabolites(P<0.05)were mainly found in the liver,circulation system and large intestine.Notably,the alteration of metabolites in tryptophan metabolism varied among organs,especially for the serotonin pathway.In GF pigs,tryptophan and kynurenine in the large intestine and 5-hydroxytryptophan in most organs were increased(P<0.05),while metabolites in the indole pathway in most organs were decreased(P<0.05).Collectively,our study reveals changes in tryptophan metabolism in GF pigs,highlighting the critical role of gut microbes in shaping host tryptophan metabolism. | Bingnan Liu Dongming Yu Jing Sun Xiaoyan Wu Zhongquan Xin Baichuan Deng Lijuan Fan Jian Fu Liangpeng Ge Wenkai Ren | 2022 | Animal Nutrition2022，，4： | 1 |
