| 1 | A new bone repair scaffold combined with chitosan/ hydroxyapatite and sustained releasing icariin显示文摘Icariin, a plant-derived flavonol glycoside, has been proved as an osteoinductive agent for bone tissue engineering. A new bone repair scaffold was generated by thorough mixing of icariin and chitosan/ hydroxyapatite (icariin-CS/HA) using freeze-drying technigue. Characteristics of morphology, mechanical properties, biocompatibility, drug release behavior and bone repair abilities in vivo were evaluated. The results show that drug loading process of icariin did not affect physical structure of CS/HA composite significantly but decreased mechanical properies of CS/HA composite, which happened with a high dosage; icariin-CS/HA had favorable cell compatibility and promoted osteogenic differentiation of hBMSCs; the controlled release of icariin was satisfactory and the release retained after 90 d in vitro. In addition, icariin-CS/HA scaffolds had favorable osteoconduction and osteoinduction in vivo, and could fill bone defect sites and stimulate newborn bone tissues formation at early stage. On the basis of these data, icariin-CS/HA is believed to be an optical bone repair scaffold for tissue engineering. | WU Tao NAN KaiHui CHEN JingDi JIN Dan JIANG Shan ZHAO PeiRan XU JunChang DU Hao ZHANG XiaoQiang LI JianWei PEI GuoXian | 2009 | Chinese Science Bulletin2009，54，17： | 14 |

| 6 | New Tapejarid Pterosaur from Western Liaoning, China显示文摘A new tapejarid pterosaur Huaxiapterus jii gen. et sp. nov. is erected based on a nearly complete skeleton with a skull. The skull morphology of Huaxiapterus jii gen. et sp. nov. appears transitional between the skulls of Sinopterus and Tapejara. The skull morphology (low crest) of Huaxiapterus jii indicates that Huaxiapterus is more closely related to Sinopterus than to Tapejara, which has a high crest. The relatively long and shallow skull of Sinopterus indicates that it is a primitive form. Huaxiapterus is more derived than Sinopterus but more primitive than Tapejara. | Lü Junchang YUAN Chongxi | 2005 | Acta Geologica Sinica(English Edition)2005，79，4： | 8 |
| 7 | Distributed and Weighted Extreme Learning Machine for Imbalanced Big Data Learning显示文摘The Extreme Learning Machine(ELM) and its variants are effective in many machine learning applications such as Imbalanced Learning(IL) or Big Data(BD) learning. However, they are unable to solve both imbalanced and large-volume data learning problems. This study addresses the IL problem in BD applications. The Distributed and Weighted ELM(DW-ELM) algorithm is proposed, which is based on the Map Reduce framework. To confirm the feasibility of parallel computation, first, the fact that matrix multiplication operators are decomposable is illustrated.Then, to further improve the computational efficiency, an Improved DW-ELM algorithm(IDW-ELM) is developed using only one Map Reduce job. The successful operations of the proposed DW-ELM and IDW-ELM algorithms are finally validated through experiments. | Zhiqiong Wang Junchang Xin Hongxu Yang Shuo Tian Ge Yu Chenren Xu Yudong Yao | 2017 | Tsinghua Science and Technology2017，22，2： | 8 |

| 9 | A New Giant Compsognathid Dinosaur with Long Filamentous Integuments from Lower Cretaceous of Northeastern China显示文摘A new compsognathid dinosaur, Sinocalliopteryx gigas gen. et sp. nov., is erected based on a complete skeleton from the Early Cretaceous Yixian Formation of western Liaoning, northeastern China. It shares the features with Huaxiagnathus orientalis in having a manus as long as the humerus plus radius, very large and subequally long manual claws I and II, and reduced olecranon process on the ulna. But it differs from Huaxiagnathus orientalis in having the much large size, a very long maxillary process of premaxilla not extending the vertical level of the maxillary antorbital fossa, and the proportionally longer ulna and so on. Sinocalliopteryx gigas gen. et sp. nov. represents the largest species among the known compsognathid dinosaurs, suggesting the tendency of the body enlargement in compsognathids to some extent. The long filamentous integuments are attached to the whole body of this compsognathid, confirming that such integuments evolved firstly in the basal coelurosaurs. This new giant compsognathid was a fierce carnivorous theropod, as shown further by an incomplete dromaeosaurid leg inside its abdominal cavity. | JI Shu' an JI Qiang LU Junchang YUAN Chongxi | 2007 | Acta Geologica Sinica(English Edition)2007，81，1： | 7 |
| 10 | Largest Toothed Pterosaur Skull from the Early Cretaceous Yixian Formation of Western Liaoning, China, with Comments on the Family Boreopteridae显示文摘A new pterosaur Moganopterus zhuiana gen. et sp. nov. is erected based on a complete skull with lower jaws and anterior cervical vertebrae. It is characterized by much elongated upper and lower jaws with at least 62 total, long, curved teeth with sharp tips, a well developed parietal crest extending posterodorsally, forming an angle of 15 degrees with the ventral margin of the skull, the ratio of length to width of cervical vertebrae greater than 5:1. The skull length is 750 mm, and it is the largest toothed pterosaur found so far in the world. Based on this new pterosaur, the Boreopteridae can be divided into two subgroups: Boreopterinae sub-fam. nov. and Moganopterinae sub-fam. nov., which is also confirmed by the phylogenetic analysis. | LU Junchang PU Hanyong XU Li WU Yanhua WEI Xuefang | 2012 | Acta Geologica Sinica(English Edition)2012，86，2： | 6 |
| 11 | A New Oviraptorid Dinosaur (Theropoda: Oviraptorosauria) from the Late Cretaceous of Jiangxi Province, Southern China显示文摘A new oviraptorid dinosaur Jiangxisaurus ganzhouensis gen. et sp. nov., is erected based on a partial skeleton from the Upper Cretaceous Nanxiong Formation of Ganzhou City, Jiangxi Province. The new taxon differs from other oviraptorids in the weakly downturned rostrum of the lower jaw, much-elongated mandible with a height-to-length ratio being about 20% and the length ratio of radius to humerus of about 0.70. This species not only adds a new member to oviraptorid dinosaurs, but also provides more information about oviraptorid paleogeographical distribution in southern China. | WEI Xuefang PU Hanyong XU Li LIU Di Lü Junchang | 2013 | Acta Geologica Sinica(English Edition)2013，87，4： | 6 |
| 12 | A New Somphospondylan Sauropod (Dinosauria, Titanosauriformes) from the Late Cretaceous of Ganzhou, Jiangxi Province of Southern China显示文摘A new somphospondylan sauropod (Dinosauria, Titanosauriformes): Gannansaurus sinensis gen. et sp. nov. from the Late Cretaceous Nanxiong Formation of Ganzhou Basin, Jiangxi Province of southern China is erected based on one nearly complete dorsal vertebra and a mid-caudal vertebra. It is characterized by two centroprezygapophyseal lamina fossae; large, square-shaped concavity formed by centroprezygapophyseal lamina and dorsal margin of the centrum; large infraparapophyseal fossa; three openings present within the large lateral concavity, which occupy 65% length of the centrum; the posterior centroparapophyseal lamina (PCPL) and the anterior centroparapophyseal lamina (ACPL) weakly developed; the posterior centrodiapophyseal lamina (PCDL) separated by an infradiapophyseal fossa into two branches dorsally; parapophyseal and diapophyseal laminae cross to form 'K' configuration. It shares some characters with the Early Cretaceous form-Euhelopus, indicating that it is more closely related to Euhelopus rather than to other titanosauriform sauropods. This means Gannansaurus may have a close phylogenetic relationship with Euhelopus. | Lü Junchang YI Laiping ZHONG Hui WEI Xuefang | 2013 | Acta Geologica Sinica(English Edition)2013，87，3： | 5 |

The new specimen is referred to Dendrorhynchoides, based on the general morphology of the skeleton, but it represents a new species, named here as Dendrorhynchoides mutoudengensis sp. nov.. It is characterized by the presence of short, robust and straight teeth, and bearing wing metacarpal approximately 40% of the length of humerus. The new specimen provides further osteological information for anurognathid pterosaurs, especially the presence of a relatively elongate tail. | LÜ Junchang David W.E.HONE | 2012 | Acta Geologica Sinica(English Edition)2012，86，6： | 5 |

| 15 | New Eusauropod Dinosaur from Yuanmou of Yunnan Province, China显示文摘Yuanmousaurus jiangyiensis gen. et sp. nov. is erected based on an incomplete skeleton. It is characterized by more complex structures of the neural arches in the dorsal vertebrae than those in Omeisaurus, but less complex than those of Euhelopus; the dorsal vertebra bears 9 laminae, forming three cavities on the lateral surface of the neural arch; the dorsal vertebral neural spines with dorsoventrally-oriented cavities are similar to those of Omeisaurus and Patagosaurus. Yuanmousaurus is more primitive than Euhelopus, but more derived than Omeisaurus. The similar dorsal vertebral structure between Yuanmousaurus and Patagosaurus may indicate that they have a close relationship to each other. | LUE Junchang LI Shaoxue JI Qiang WANG Guofu ZHANG Jiahua DONG Zhiming | 2006 | Acta Geologica Sinica(English Edition)2006，80，1： | 5 |

| 17 | In vitro effects of sodium hyaluronate on the proliferation and the apoptosis in chondrocytes from patients with Kashin-Beck disease and osteoarthritis显示文摘Objective:To identify the in vitro effects of sodium hyaluronate(HA) on the proliferation and the apoptosis of chondrocytes from patients with Kashin-Beck disease(KBD) and osteoarthritis(OA). Methods:Samples of articular cartilages from KBD and OA patients, as well as healthy volunteers(6 subjects in each of the 3 groups) were dissected, digested with collagenase and the cells cultured in monolayers. Chondrocytes from each sample were assigned to an untreated group and two HA-treated groups: H0(no HA), H100(HA, 0.1 g/L) and H500(HA, 0.5 g/L). The first passage chondrocytes were used to observe proliferation using the MTT assay, and apoptosis by flow cytometry through Annexin V/PI staining. Results:HA promoted proliferation of chondrocytes in all the three groups, and in KBD and OA groups, for cells cultured for 4 and 6 days, H500 significantly promoted the cell proliferation. The apoptotic rates of both KBD and OA group chondrocytes were in the order H500 < HA100 < H0. Conclusion:Sodium hyaluronate administration has a dose-dependent in vitro effect to promote proliferation and inhibit apoptosis of chondrocytes from patients with KBD and OA. | Zongqiang Gao Xiong Guo Chen Duan Weijuan Ma Peng Xu Ruiyu Liu Qisheng Gu Junchang Chen | 2009 | Journal of Nanjing Medical University2009，23，2： | 5 |

| 20 | A new pterosaur (Pterosauria) from Middle Jurassic Tiaojishan Formation of western Liaoning,China显示文摘A new pterosaur Archaeoistiodactylus linglongtaensis gen. et sp. nov. is erected based on an incomplete skeleton with a partial skull and lower jaw. The new taxon is characterized by circular tooth sockets of anterior mandibular teeth,the anterior teeth of the upper jaw bearing posteriorly directed crowns,a relatively short metacarpus,and wing phalanges 2 and 3 and the tibia subequal in length. It possesses some plesiomorphic characters such as short metacarpals and circular tooth sockets. The pointed jaw tip present in the new taxon indicates that the expanded jaw tips of later istiodactylids are a derived character state,and the new taxon represents the first istiodactylus-like pterosaur found from the pre-Late Jurassic deposits,which provides a key role in our understanding the origin and evolution of the known istiodactylid pterosaurs. Archaeoistiodactylus is regarded as the ancestor form of the known istiodactylid pterosaur. | LU Junchang FUCHA Xiaohui | 2010 | Global Geology2010，13，3： | 4 |
