| 1 | Progress and significance in research on the early Middle Cambrian Kaili Biota, Guizhou Province, China显示文摘Important progress in research on the Kaili Biota has been made recently. Many interesting components from Chengjiang Biota and Burgess Shale Biota have been discovered, e.g. Microdictyon of lobopodia; Ottoia, Palaeoscolex of worms; Naraoia, Marrella of Trilobitioidea, Mollisonia, anamalocarids and other non-trilobite arthropods; and new sorts of echinoder-mas, macroalage fossils and so on. Recent work on the Kaili Biota has resulted in the following developments: (i) an increase in the number of animal genera, up to more than 100 genera in total, so that the Kaili Biota has become the third most diverse of the Burgess Shale-type Biota after the Burgess Shale and Chengjiang Biotas; and (ii) the most noteworthy fossils in the Kaili Biota are echinoderms, non-trilobite arthropods and soft-bodied medusiform fossils, especially the most diverse echinoderms. The progress provides envidence for the biodiversity of marine organisms presented after the 'Cambrian Explosion' and serves as a link between the earlist Cambrian Chengjiang Biota and late early Middle Cambrian Burgess Shale Biota. It is of great significance in the reconstruction of the Cambrian palaeoplate, palaeongeography and in research on taphonomy. | ZHAO Yuanlong, YUAN Jinliang, ZHU Maoyan, YANG Ruidong, GUO Qingjun, PENG Jin and YANG Xinglian(1.

| 2 | Abnormal subchondral bone remodeling and its association with articular cartilage degradation in knees of type 2 diabetes patients显示文摘Type 2 diabetes(T2 D) is associated with systemic abnormal bone remodeling and bone loss. Meanwhile,abnormal subchondral bone remodeling induces cartilage degradation, resulting in osteoarthritis(OA).Accordingly, we investigated alterations in subchondral bone remodeling, microstructure and strength in knees from T2 D patients and their association with cartilage degradation. Tibial plateaus were collected from knee OA patients undergoing total knee arthroplasty and divided into non-diabetic(n = 70) and diabetes(n = 51) groups. Tibial plateaus were also collected from cadaver donors(n = 20) and used as controls.Subchondral bone microstructure was assessed using micro-computed tomography. Bone strength was evaluated by micro-finite-element analysis. Cartilage degradation was estimated using histology. The expression of tartrate-resistant acidic phosphatase(TRAP), osterix, and osteocalcin were calculated using immunohistochemistry. Osteoarthritis Research Society International(OARSI) scores of lateral tibial plateau did not differ between non-diabetic and diabetes groups, while higher OARSI scores on medial side were detected in diabetes group. Lower bone volume fraction and trabecular number and higher structure model index were found on both sides in diabetes group. These microstructural alterations translated into lower elastic modulus in diabetes group. Moreover, diabetes group had a larger number of TRAP^+ osteoclasts and lower number of Osterix^+ osteoprogenitors and Osteocalcin^+ osteoblasts. T2 D knees are characterized by abnormal subchondral bone remodeling and microstructural and mechanical impairments, which were associated with exacerbated cartilage degradation. In regions with intact cartilage the underlying bone still had abnormal remodeling in diabetes group, suggesting that abnormal bone remodeling may contribute to the early pathogenesis of T2 D-associated knee OA. | Yan Chen Yong-Can Huang Chun Hoi Yan Kwong Yuen Chiu Qingjun Wei Jingmin Zhao X Edward Guo Frankie Leung William W Lu | 2017 | Bone Research2017，5，4： | 10 |

| 4 | A biooptical model of retrieving petroleum concentration in seawater显示文摘A biooptical modeling, which is based on a radiation transfer model, can be employed to simultaneously retrieve the concentration of various colour factors by multi-spectral remote sensing data, after connecting inherent optical properties(absorption coefficient and backward scattering coefficient) of colour factor with apparent optical properties(remote sensing reflectivity). At present, this method has been used in a relatively wide range of applications in the inversion of a conventional water colour factor concentration in the case II water body: applications such as chlorophyll, suspended sediment, yellow substance. On the basis of extensive field testing data of water quality, correspondingly apparent optical properties, and the full use of the existing parametric model of colour factor inherent optical properties(with the parametrization of petroleum substance inherent optical properties established in the project) the remote recognition model for oil concentration is established by introducing oil as a new water colour factor into a biooptical remote algorithm. The estimated value of the oil concentration was obtained by solving the biooptical model, using the data measured in May 2008 and August 2009 and June 2010 in seawater. The highly accurate inversion result promises to estimate the oil concentration in water for remote sensing. | HUANG Miaofen SONG Qingjun XING Xufeng ZHAO Zulong | 2014 | Acta Oceanologica Sinica2014，33，5： | 8 |

| 6 | Locomotor activity and anxiety status, but not spatial working memory,are affected in mice after brief exposure to cuprizone显示文摘Chronic long-term exposure to cuprizone causes severe brain demyelination in mice,which leads to changes in locomotion,working memory and anxiety.These findings suggest the importance of intact myelin for these behaviors.This study aimed to investigate the possible behavioral changes in mice with mild oligodendrocyte/myelin damage that parallels the white matter changes seen in the brains of patients with psychiatric disporders.We used the cuprizonetreated mouse model to test both tissue changes and behavioral functions(locomotor activity,anxiety status,and spatial working memory).The results showed that mice given cuprizone in their diet for 7 days had no significant myelin breakdown as evaluated by immunohistochemical staining for myelin basic protein,while the number of mature oligodendrocytes was reduced.The number and length of Caspr protein clusters,a structural marker of the node of Ranvier,did not change.The locomotor activity of the cuprizonetreated mice increased whereas their anxiety levels were lower than in normal controls;spatial working memory,however,did not change.These results,for the first time,link emotion-related behavior with mild white matter damage in cuprizone-treated mice. | Handi Zhang Yanbo Zhang Haiyun Xu Lingyan Wang Jinsong Zhao Junhui Wang Zhijun Zhang Qingrong Tan Jiming Kong Qingjun Huang Xin-Min Li | 2013 | Neuroscience Bulletin2013，29，5： | 4 |
| 7 | A restudy of Oryctocephalus indicus (Reed,1910)显示文摘Restudy on morphology of Oryctocephalus indicus (Reed, 1910), based on specimens from Guizhou, China and Nevada USA, suggests that the subspecies regarded previously as Oryctocephalus indicus indicus (Reed, 1910), O. indicus latus Zhao et Yuan 2002, and O. indicus kobayashi Saito, 1934, are synonymous, and Oryctocephalus americanus Sundberg et McCollum, 2003 is a similar form of O. indicus. Oryctocephalus indicus is rediagnosed as having a glabella that is subconical in outline and tapering forward slightly; a thorax that comprises 12 segments, and a small pygidium that bears 2—3 axial rings with a terminal piece and a postaxial ridge. Oryctocephalus indicus is widely distributed in eastern Guizhou and ranges through a great interval of Kaili Formation. Its first appearance is almost identical with these events of trilobite extinction-recovery occurring at the end of the Early Cambrian, the alternation of acritach assemblages, the change of trace elements (REE) and stable isotopes (carbon) at the Wuliu-Zengjiaya section. As one of the key forms for defining the traditional Lower-Middle Cambrian boundary (the base of Cambrian Series 3 and Stage 5 in the new Cambrian chronstratigraphic standard), O. indicus has received detailed study and has more advantages than other species such as Ovatoryctocara granulata Tchernysheva, 1962 or Arthricocephalus chauveaui Bergeron, 1899. | ZHAO Yuanlong YUAN Jinlian PENG Shanchi YANG Xinglian PENG Jin LIN Jihpai GUO Qingjun | 2006 | Progress in Natural Science:Materials International2006，16，11： | 4 |
| 8 | Investigation of influencing factors of hot streaks migration in high pressure stage of a vaneless counter-rotating turbine显示文摘Three-dimensional,viscous,and unsteady CFD simulations have been performed in order to reveal the influencing factors of hot streaks migration in high pressure stage of a vaneless counter-rotating turbine. Based on the numerical results,the comparison between the case with inlet hot streaks and case without inlet hot streaks is carried out,which shows that the effect of inlet hot streaks on the load distributions of high pressure turbine airfoils is not notable and the airfoil load distributions are directly related to the inlet pressure distributions. The predicted results also indicate that the circumferential and radial movements of the hot streaks were not observed in the high pressure turbine stator. This means that the combined effects of secondary flow and buoyancy are very weak in the high pres-sure turbine stator. The numerical results also prove that the circumferential flow angle effect at the inlet of the high pressure turbine rotor,secondary flow effect and buoyancy effect are the mainly influencing factors to directly affect the migration characteristics of the hot streaks in the high pressure turbine rotor. | ZHAO QingJun WANG HuiShe TANG Fei ZHAO XiaoLu XU JianZhong | 2008 | Science China(Technological Sciences)2008，51，2： | 4 |
| 9 | Simultaneous removal of gaseous CO and elemental mercury over Cu-Co modified activated coke at low temperature显示文摘Cu-Co multiple-oxides modified on HNO_3-pretreated activated coke(AC_(N))were optimized for the simultaneous removal of gaseous CO and elemental mercury(Hg^(0))at low temperature(<200℃).It was found that 2%CuOx-10%CoOx/AC_(N)catalyst calcined at 400℃resulted in the coexistence of complex oxides including CuO,Cu_2 O,Co_(3)O_(4,Co_(2)O_(3)and CoO phases,which might be good for the simultaneous catalytic oxidation of CO by Co-species and removal of Hg^(0)by Cu-species,benefiting from the synergistic catalysis during the electrointeraction between Go and Cu cations(CoO■Co_(3)O_(4)and Cu_(2)O■CuO).The catalysis removal of CO oxidation was obviously depended on the reaction temperature obtaining94.7%at 200℃,while no obvious promoting effect on the Hg^(0)removal(68.3%-78.7%).These materials were very substitute for the removal of CO and Hg^(0)from the flue gas with the conditions of 8-20 vol.%O_(2)and flue-gas temperature below 200℃.The removal of Hg^(0)followed the combination processes of adsorption and catalytic oxidation reaction via LangmuirHinshelwood mechanism,while the catalysis of CO abided by the Mars-van Krevelen mechanism with lattice oxygen species. | Fengyu Gao Hao Yan Xiaolong Tang Honghong Yi Shunzheng Zhao Qingjun Yu Shuquan Ni | 2021 | Journal of Environmental Sciences2021，33，3： | 3 |
| 10 | The Effect of 2,5-hexanedione on Myelin Protein Zero Expression,and Its Mitigation Using Ginkgo Biloba Extract显示文摘Objective To investigate the role of myelin protein zero (P 0) in 2,5-hexanedione (2,5-HD)-induced peripheral nerve injury,and the protective effect of Ginkgo biloba extract (Egb761) on 2,5-HD-induced toxic peripheral neuropathy.Methods After 4 weeks of treatment with 2,5-HD at different doses (50,100,200,400 mg/kg) in rats,changes in the levels of P 0 in rat sciatic nerves was investigated,and the effect of Egb761 on 2,5-HD-induced toxic peripheral neuropathy was studied.Results The blood-nerve barrier (BNB) permeability of the sciatic nerve increased,and the expression of P 0 mRNA and P 0 protein decreased in a dose-dependent manner after treatment with 2,5-HD for 4 weeks.Pretreatment with Egb761 protected against BNB interruption,and inhibited P 0 mRNA and protein reduction during 2,5-HD treatment.Pretreatment with Egb761 significantly reduced loss of body weight (P<0.01) and mitigated gait abnormalities (2.85±0.22) induced by 400 mg/kg 2,5-HD (P<0.01).It also reduced the signs of neurotoxicity induced by 2,5-HD.Conclusion 2,5-HD inhibited the expression of P 0 in a dose-dependent manner,and this may be an important mechanism by which toxic peripheral neuropathy is induced by 2,5-HD.Egb761 has a protective effect against 2,5-HD-induced peripheral neurotoxicity in rats. | ZHAO Lei LIU QingJun CHEN Hong DUAN HuaWei BIN Ping LIU Qing NIU Yong DAI YuFei ZHENG YuXin | 2011 | Biomedical and Environmental Sciences2011，24，4： | 3 |
| 11 | Predicting lean blow-off of bluffbody stabilized flames based on Damkohler number显示文摘Lean Blow-Off(LBO) prediction is important to propulsion system design. In this paper,a hybrid method combining numerical simulation and Da(Damk?hler) model is proposed based on bluffbody stabilized flames. In the simulated reacting flow, Practical Reaction Zone(PRZ) is built based on OH radical concentration, and it is considered to be the critical zone that controls LBO.Da number is obtained based on the volume-averaged parameters of PRZ. The flow time scale(s_f)indicates the residence time of the fresh mixture flowing through the PRZ. It is obtained based on the characteristic length and volume-averaged axial velocity of the PRZ. The chemical time scale(s_c) indicates the shortest time needed to trigger the reaction of the mixture. It is obtained by commercial software CHEMKIN through monitoring the transient variation of the reactor temperature. The result shows that the average Da number under different LBO conditions is 1.135(the Da number under each LBO condition ranges from 0.673 to 1.351). This indicates that the flow time scale and chemical time scale are comparable. The combustion is in a critical state where LBO is easy to occur. With the increase of the fuel mass flow rate(the global fuel/air ratio increases from 0.004761 to 0.01095), s_f increases from 0.001268 s to 0.007249 s, and s_c decreases from 0.00124 s to0.00089 s. Accordingly, Da number increases from 1.023 to 8.145, which shows that the combustion becomes more stable. The above results show that the method proposed in the present study can properly predict the LBO limits of combustors, which provides important technical supports for combustor design and optimization. | Zhonghao WANG Bin HU Aiming DENG Junhua ZHANG Qingjun ZHAO | 2019 | Chinese Journal of Aeronautics2019，32，2： | 2 |

| 15 | Intrinsic physical relationships between rotor modal shapes and instantaneous vibrational energy flow transmission characteristics:Theoretical and numerical analysis and application显示文摘The modal vibration of the rotor is the main cause of excessive vibration of the aeroengine overall structure.To attenuate the vibration of the rotor under different modal shapes from the perspective of energy control,the intrinsic physical relationships between rotor modal shapes and instantaneous vibrational energy flow transmission characteristics is derived from the general equation of motion base on the structural intensity method.A dual-rotor-support-casing coupling model subjected to the rotor unbalanced forces is established by the finite element method in this paper.The transmission,conversion and balance relationships of the vibrational energy flow for the rotors in the first-order bending modal shape,the conical whirling modal shape and the translational modal shape are analyzed,respectively.The results show that the vibrational energy flow transmitted to the structure can be converted into the strain energy,the kinetic energy and the energy dissipated by the damping of the structure.The vibrational energy flow transmission characteristics of rotors with different modal shapes are quite different.Especially for the first-order bending modal shape,the vibrational energy flow and the strain energy are transmitted and converted to each other in the middle part of the rotor shaft,resulting in large deformation at this part.To attenuate this harmful vibration,the influences of grooving on the shaft on the first-order bending vibration are studied from the perspective of transmission control of vibrational energy flow.This study can provide theoretical references and guidance for the vibration attenuation of the rotors in different modal shapes from a more essential perspective. | Yingqun MA Qingjun ZHAO Wei ZHAO Binbin LIU Long HAO | 2020 | Chinese Journal of Aeronautics2020，33，12： | 1 |
