3Anti-oxidant effect of picroside II in a rat model of cerebral ischemia/reperfusion injury显示文摘Picroside II,the major active component of picroside,has been shown to induce PC12 cell axonal growth and relieve free radical damage.In vivo experiments have demonstrated that picroside II can improve neurological function in rats with cerebral ischemia/reperfusion injuries.In the present in vivo study,enzyme-linked immunosorbent assay and immunohistochemistry revealed that picroside II increased superoxide dismutase content and reduced inducible nitric oxide synthase content in the ischemic hemisphere.The effects of picroside II were similar to those of salvianic acid A sodium,an active control drug.These results indicate that picroside II exerts a neuroprotective effect,possibly by downregulating inducible nitric oxide synthase expression,increasing superoxide dismutase activity,and inhibiting neuronal apoptosis.Li Sun Xiaodan Li Ling Wang Lihua Qin Yunliang Guo Zhen Zhou 2011Neural Regeneration Research2011,6,15:8

5Improvements of corner frequency and scaling factor for stochastic finite-fault modeling显示文摘In this paper, three existing source spectral models for stochastic finite-fault modeling of ground motion were reviewed. These three models were used to calculate the far-field received energy at a site from a vertical fault and the mean spectral ratio over 15 stations of the Northridge earthquake, and then compared. From the comparison, a necessary measure was observed to maintain the far-field received energy independent of subfault size and avoid overestimation of the long-period spectral level. Two improvements were made to one of the three models (i.e., the model based on dynamic corner frequency) as follows: (i) a new method to compute the subfault corner frequency was proposed, where the subfault corner frequency is determined based on a basic value calculated from the total seismic moment of the entire fault and an increment depending on the seismic moment assigned to the subfault; and (ii) the difference of the radiation energy from each subfault was considered into the scaling factor. The improved model was also compared with the unimproved model through the far-field received energy and the mean spectral ratio. The comparison proves that the improved model allows the received energy to be more independent of subfault size than the unimproved model, and decreases the overestimation degree of the long-period spectral amplitude.Sun Xiaodan Tao Xiaxin Chen Fu 2010Earthquake Engineering and Engineering Vibration2010,9,4:5
6Enhanced angiogenesis by the hyaluronic acid hydrogels immobilized with a VEGF mimetic peptide in a traumatic brain injury model in rats显示文摘Angiogenesis plays an important role in brain injury repair,which contributes to the reconstruction of regenerative neurovascular niche for promoting axonal regeneration in the lesion area.As a major component of developing brain extracellular matrix,hyaluronic acid(HA)has attracted more attention as a supporting matrix for brain repair.In the present study,HA-KLT hydrogel was developed via modifying HA with a VEGF mimetic peptide of KLT(KLTWQELYQLKYKGI).The characterization of the hydrogel shows that it could provide a porous,three-dimensional scaffold structure,which has a large specific surface area available for cell adhesion and interaction.Compared with the unmodified HA hydrogel,the HA-KLT hydrogel could effectively promote the attachment,spreading and proliferation of endothelial cells in vitro.Furthermore,the pro-angiogenic ability of hydrogels in vivo was evaluated by implanting them into the lesion cavities in the injured rat brain.Our results showed that the hydrogels could form a permissive interface with the host tissues at 4 weeks after implantation.Moreover,they could efficiently inhibit the formation of glial scars at the injured sites.The HA-KLT hydrogel could significantly increase the expression of endoglin/CD105 and promote the formation of blood vessels,suggesting that HA-KLT hydrogel promoted angiogenesis in vivo.Collectively,the HA-KLT hydrogel has the potential to repair brain defects by promoting angiogenesis and inhibiting the formation of glial-derived scar tissue.Jiaju Lu Fengyi Guan Fuzhai Cui Xiaodan Sun Lingyun Zhao Ying Wang Xiumei Wang 2019Regenerative Biomaterials2019,6,6:5

8Hybrid superhydrophilic-superhydrophobic micro/nanostructures fabricated by femtosecond laserinduced forward transfer for sub-femtomolar Raman detection显示文摘Raman spectroscopy plays a crucial role in biochemical analysis.Recently,superhydrophobic surface-enhanced Raman scattering(SERS)substrates have enhanced detection limits by concentrating target molecules into small areas.However,due to the wet transition phenomenon,further reduction of the droplet contact area is prevented,and the detection limit is restricted.This paper proposes a simple method involving femtosecond laser-induced forward transfer for preparing a hybrid superhydrophilic–superhydrophobic SERS(HS-SERS)substrate by introducing a superhydrophilic pattern to promote the target molecules to concentrate on it for ultratrace detection.Furthermore,the HS-SERS substrate is heated to promote a smaller concentrated area.The water vapor film formed by the contact of the solution with the substrate overcomes droplet collapse,and the target molecules are completely concentrated into the superhydrophilic region without loss during evaporation.Finally,the concentrated region is successfully reduced,and the detection limit is enhanced.The HS-SERS substrate achieved a final contact area of 0.013mm2,a 12.1-fold decrease from the unheated case.The reduction of the contact area led to a detection limit concentration as low as 10−16 M for a Rhodamine 6G solution.In addition,the HS-SERS substrate accurately controlled the size of the concentrated areas through the superhydrophilic pattern,which can be attributed to the favorable repeatability of the droplet concentration results.In addition,the preparation method is flexible and has the potential for fluid mixing,fluid transport,and biochemical sensors,etc.Xiaodan Ma Lan Jiang Xiaowei Li Bohong Li Ji Huang Jiaxing Sun Zhi Wang Zhijie Xu Liangti Qu Yongfeng Lu Tianhong Cui 2019Microsystems & Nanoengineering2019,5,1:3
9Open N-doped carbon coated porous molybdenum phosphide nanorods for synergistic catalytic hydrogen evolution reaction显示文摘Molybdenum phosphide is a potential hydrogen evolution reaction(HER)catalyst.However,traditional high-temperature phosphating preparation methods are prone to damage of material morphology and agglomeration.Using the carbon skeleton to limit the size and morphology of MoP and to improve the conductivity of the material is an effective method to improve the performance of the catalyst.However,there is a lack of research on the effect of carbon skeleton and MoP composite structure on the catalytic mechanism of HER.We coated ZIF-8 on the surface of MoP nanorods,and obtained open N-doped carbon-coated porous MoP nanorods(N/C/MoP)through carbonization and phosphating.Studies have shown that the ZIF-8 coating effectively limits the size and morphology of the material and avoids agglomeration.Under alkaline conditions,N/C/MoP has a low overpotential of 169 mV for HER at 10 mA/cm2,which is 55 mV lower than MoP without a carbon layer.At the same time,its Tafel slope(51.3 mV/dec)is smaller than Pt/C(59.9 mV/dec),and it has good stability.Density functional theory(DFT)studies have shown that under alkaline conditions,there is a synergistic effect between the open N-doped carbon layer and the exposed MoP active surface,which reduces the activation energy of water and improves the catalytic performance of HER.It is worth noting that a tight coating will hinder the exposure of active sites and reduce catalytic activity.Chao Wang Wen Li Xiaodan Wang Nan Yu Hongxia Sun Baoyou Geng 2022Nano Research2022,15,3:3
10Dynamic corner frequency in source spectral model for stochastic synthesis of ground motion显示文摘The static corner frequency and dynamic corner frequency in stochastic synthesis of ground motion from finite-fault modeling are introduced, and conceptual disadvantages of the two are discussed in this paper. Furthermore, the non-uniform radiation of seismic wave on the fault plane, as well as the trend of the larger rupture area, the lower corner frequency, can be described by the source spectral model developed by the authors. A new dynamic corner frequency can be developed directly from the model. The dependence of ground motion on the size of subfault can be eliminated if this source spectral model is adopted in the synthesis. Finally, the approach presented is validated from the comparison between the synthesized and observed ground motions at six rock stations during the Northridge earthquake in 1994.Xiaodan Sun Xiaxin Tao Guoxin Wang Taojun Liu 2009Earthquake Science2009,22,3:3
11Organic mulching promotes soil organic carbon accumulation to deep soil layer in an urban plantation forest显示文摘Background:Soil organic carbon(SOC)is important for soil quality and fertility in forest ecosystems.Labile SOC fractions are sensitive to environmental changes,which reflect the impact of short-term internal and external management measures on the soil carbon pool.Organic mulching(OM)alters the soil environment and promotes plant growth.However,little is known about the responses of SOC fractions in rhizosphere or bulk soil to OM in urban forests and its correlation with carbon composition in plants.Methods:A one-year field experiment with four treatments(OM at 0,5,10,and 20 cm thicknesses)was conducted in a 15-year-old Ligustrum lucidum plantation.Changes in the SOC fractions in the rhizosphere and bulk soil;the carbon content in the plant fine roots,leaves,and organic mulch;and several soil physicochemical properties were measured.The relationships between SOC fractions and the measured variables were analysed.Results:The OM treatments had no significant effect on the SOC fractions,except for the dissolved organic carbon(DOC).OM promoted the movement of SOC to deeper soil because of the increased carbon content in fine roots of subsoil.There were significant correlations between DOC and microbial biomass carbon and SOC and easily oxidised organic carbon.The OM had a greater effect on organic carbon fractions in the bulk soil than in the rhizosphere.The thinnest(5 cm)mulching layers showed the most rapid carbon decomposition over time.The time after OM had the greatest effect on the SOC fractions,followed by soil layer.Conclusions:The frequent addition of small amounts of organic mulch increased SOC accumulation in the present study.OM is a potential management model to enhance soil organic matter storage for maintaining urban forest productivity.Xiaodan Sun Gang Wang Qingxu Ma Jiahui Liao Dong Wang Qingwei Guan Davey L.Jones 2021Forest Ecosystems2021,8,1:2
12Strongly coupled Te-SnS_(2)/MXene superstructure with self-autoadjustable function for fast and stable potassium ion storage显示文摘Potassium-ion batteries(PIBs)are a promising candidate for next-generation electric energy storage applications because of the abundance and low cost of potassium.However,the development of PIBs is limited by sluggish kinetics and huge volume expansion of anodes,leading to poor rate capability and cycling stability.Herein,an advanced superstructure anode,including Te-doped SnS_(2) nanosheets uniformly anchored on MXene surface(Te-SnS_(2)/MXene),is rationally designed for the first time to boost K^(+)storage performance.Featuring with strong interface interaction and self-autoadjustable interlayer spacings,the Te-SnS_(2)/MXene can efficiently accelerate electron/ion transfer,accommodate volume expansion,inhibit crack formation,and improve pseudocapacitive contribution during cycling.Thus,the novel Te-SnS_(2)/MXene anode delivers a high reversible capacity(343.2 mAh g^(-1) after 50 cycles at0.2 A g^(-1)),outstanding rate capability(186.4 mAh g^(-1) at 20 A g^(-1)),long cycle stability(165.8 mAh g^(-1)after 5000 cycles at 10 A g^(-1) with a low electrode swelling rate of only 15.4%),and reliable operation in flexible full battery.The present Te-SnS_(2)/MXene becomes among the best transition metal-based anode materials for PIBs reported to date.Hongyang Sun Yelong Zhang Xiaodan Xu Jianwen Zhou Fan Yang Hao Li Hao Chen Yucheng Chen Zheng Liu Zhenping Qiu Da Wang Lipo Ma Jiawei Wang Qingguang Zeng Zhangquan Peng 2021Journal of Energy Chemistry2021,30,10:2

14In vivo evaluation of additively manufacturedmulti-layered scaffold for the repair of large osteochondral defects显示文摘The repair of osteochondral defects is one of the major clinical challenges in orthopaedics.Well-established osteochondral tissue engineering methods have shown promising results for the early treatment of small defects.However,less success has been achieved for the regeneration of large defects,which is mainly due to the mechanical environment of the joint and the heterogeneous nature of the tissue.In this study,we developed a multi-layered osteochondral scaffold to match the heterogeneous nature of osteochondral tissue by harnessing additive manufacturing technologies and combining the established art laser sintering and material extrusion techniques.The developed scaffold is based on a titanium and polylactic acid matrix-reinforced collagen“sandwich”composite system.The microstructure and mechanical properties of the scaffold were examined,and its safety and efficacy in the repair of large osteochondral defects were tested in an ovine condyle model.The 12-week in vivo evaluation period revealed extensive and significantly higher bone in-growth in the multi-layered scaffold compared with the collagen–HAp scaffold,and the achieved stable mechanical fixation provided strong support to the healing of the overlying cartilage,as demonstrated by hyaline-like cartilage formation.The histological examination showed that the regenerated cartilage in the multi-layer scaffold group was superior to that formed in the control group.Chondrogenic genes such as aggrecan and collagen-II were upregulated in the scaffold and were higher than those in the control group.The findings showed the safety and efficacy of the cell-free“translation-ready”osteochondral scaffold,which has the potential to be used in a one-step surgical procedure for the treatment of large osteochondral defects.Maryam Tamaddon Gordon Blunn Rongwei Tan Pan Yang Xiaodan Sun Shen-Mao Chen Jiajun Luo Ziyu Liu Ling Wang Dichen Li Ricardo Donate Mario Monzón Chaozong Liu 2022Bio-Design and Manufacturing2022,5,3:2

20Osteochondral scaffolds for early treatment of cartilage defects in osteoarthritic joints:from bench to clinic显示文摘Osteoarthritis is a degenerative joint disease,typified by the loss in the quality of cartilage and bone at the interface of a synovial joint,resulting in pain,stiffness and reduced mobility.The current surgical treatment for advanced stages of the disease is joint replacement,where the non-surgical therapeutic options or less invasive surgical treatments are no longer effective.These are major surgical procedures which have a substantial impact on patients’quality of life and lifetime risk of requiring revision surgery.Treatments using regenerative methods such as tissue engineering methods have been established and are promising for the early treatment of cartilage degeneration in osteoarthritis joints.In this approach,3-dimensional scaffolds(with or without cells)are employed to provide support for tissue growth.However,none of the currently available tissue engineering and regenerative medicine products promotes satisfactory durable regeneration of large cartilage defects.Herein,we discuss the current regenerative treatment options for cartilage and osteochondral(cartilage and underlying subchondral bone)defects in the articulating joints.We further identify the main hurdles in osteochondral scaffold development for achieving satisfactory and durable regeneration of osteochondral tissues.The evolution of the osteochondral scaffolds–from monophasic to multiphasic constructs–is overviewed and the osteochondral scaffolds that have progressed to clinical trials are examined with respect to their clinical performances and their potential impact on the clinical practices.Development of an osteochondral scaffold which bridges the gap between small defect treatment and joint replacement is still a grand challenge.Such scaffold could be used for early treatment of cartilage and osteochondral defects at early stage of osteoarthritis and could either negate or delay the need for joint replacements.Maryam Tamaddon Helena Gilja Ling Wang JMiguel Oliveira Xiaodan Sun Rongwei Tan Chaozong Liu 2020Biomaterials Translational2020,1,1:1
