| 1 | Biodegradable Materials for Bone Repairs:A Review显示文摘With attractive research and development of biomaterials,more and more opportunities have been brought to the treatments of human tissue repairs.The implant is usually no need to exist in the body accompanied with the recovery or regeneration of the tissue lesions,and the long-term effect of exotic substance to human body should be reduced as lower as possible.For this purpose,biodegradable materials,including polymers, magnesium alloys and ceramics,have attracted much attention for medical applications due to their biodegradable characters in body environment.This paper in turn introduces these three different types of widely studied biodegradable materials as well as their advantages as implants in applications for bone repairs.Relevant history and research progresses are summarized. | Lili Tan Xiaoming Yu Peng Wan Ke Yang | 2013 | Journal of Materials Science & Technology2013，29，6： | 24 |
| 2 | Surface Modification on Biodegradable Magnesium Alloys as Orthopedic Implant Materials to Improve the Bio-adaptability:A Review显示文摘Magnesium(Mg) and its alloys as a novel kind of biodegradable material have attracted much fundamental research and valuable exploration to develop its clinical application. Mg alloys degrade too fast at the early stage after implantation, thus commonly leading to some problems such as osteolysis, early fast mechanical loss, hydric bubble aggregation, gap formation between the implants and the tissue. Surface modification is one of the effective methods to control the degradation property of Mg alloys to adapt to the need of organism. Some coatings with bioactive elements have been developed, especially for the micro-arc oxidation coating, which has high adhesion strength and can be added with Ca, P, and Sr elements. Chemical deposition coating including bio-mimetic deposition coating, electro-deposition coating and chemical conversion coating can provide good anticorrosion property as well as better bioactivity with higher Ca and P content in the coating. From the biodegradation study, it can be seen that surface coating protected the Mg alloys at the early stage providing the Mg alloy substrate with lower degradation rate. The biocompatibility study showed that the surface modification could provide the cell and tissue stable and weak alkaline surface micro-environment adapting to the cell adhesion and tissue growth.The surface modification also decreased the mechanical loss at the early stage adapting to the loadbearing requirement at this stage. From the interface strength between Mg alloys implants and the surrounding tissue study, it can be seen that the surface modification improved the bio-adhesion of Mg alloys with the surrounding tissue, which is believed to be contributed to the tissue adaptability of the surface modification. Therefore, the surface modification adapts the biodegradable magnesium alloys to the need of biodegradation, biocompatibility and mechanical loss property. For the different clinical application, different surface modification methods can be provided to adapt to the clinical requirements for the Mg alloy implants. | Peng Wan Lili Tan Ke Yang | 2016 | Journal of Materials Science & Technology2016，32，9： | 19 |
| 3 | Biofunctional magnesium coated Ti6Al4V scaffold enhances osteogenesis and angiogenesis in vitro and in vivo for orthopedic application显示文摘The insufficient osteogenesis and osseointegration of porous titanium based scaffold limit its further application.Early angiogenesis is important for scaffold survival.It is necessary to develop a multifunctional surface on titanium scaffold with both osteogenic and angiogenic properties.In this study,a biofunctional magnesium coating is deposited on porous Ti6Al4V scaffold.For osseointegration and osteogenesis analysis,in vitro studies reveal that magnesium-coated Ti6Al4V co-culture with MC3T3-E1 cells can improve cell proliferation,adhesion,extracellular matrix(ECM)mineralization and ALP activity compared with bare Ti6Al4V cocultivation.Additionally,MC3T3-E1 cells cultured with magnesium-coated Ti6Al4V show significantly higher osteogenesisrelated genes expression.In vivo studies including fluorochrome labeling,micro-computerized tomography and histological examination of magnesium-coated Ti6Al4V scaffold reveal that new bone regeneration is significantly increased in rabbits after implantation.For angiogenesis studies,magnesium-coated Ti6Al4V improve HUVECs proliferation,adhesion,tube formation,wound-healing and Transwell abilities.HUVECs cultured with magnesium-coated Ti6Al4V display significantly higher angiogenesis-related genes(HIF-1αand VEGF)expression.Microangiography analysis reveal that magnesium-coated Ti6Al4V scaffold can significantly enhance the blood vessel formation.This study enlarges the application scope of magnesium and provides an optional choice to the conventional porous Ti6Al4V scaffold with enhanced osteogenesis and angiogenesis for further orthopedic applications. | Peng Gao Bo Fan Xiaoming Yu Wenwen Liu Jie Wu Lei Shi Di Yang Lili Tan Peng Wan Yulin Hao Shujun Li Wentao Hou Ke Yang Xiaokang Li Zheng Guo | 2020 | Bioactive Materials2020，5，3： | 15 |
| 4 | Degradation and biological properties of Ca-P contained micro-arc oxidation self-sealing coating on pure magnesium for bone fixation显示文摘Poor corrosion resistance is one of the main disadvantages for biodegradable magnesium-based metals,especially applied for bone fixation,where there is a high demand of bio-mechanical strength and stability.Surface coating has been proved as an effective method to control the in vivo degradation.In this study a Ca-P self-sealing micro-arc oxidation(MAO)coating was studied to verify its efficacy and biological properties by in vitro and in vivo tests.It was found that the MAO coating could effectively retard the degradation according to immersion and electrochemical tests as well as 3D reconstruction by X-ray tomography after implantation.The MAO coating exhibited no toxicity and could stimulate the new bone formation.Therefore,the Ca-P self-sealing MAO coating could be a potential candidate for application of biodegradable Mg-based implant in bone fixations. | Weidan Wang Peng Wan Chen Liu Lili Tan Weirong Li Lugee Li Ke Yang | 2015 | Regenerative Biomaterials2015，2，2： | 11 |
| 5 | Fabrication and Evaluation of a Bioactive Sr–Ca–P Contained Micro-Arc Oxidation Coating on Magnesium Strontium Alloy for Bone Repair Application显示文摘Considering the compatibility between degradation and bioactivity of magnesium-based implants for bone repair, micro-arc oxidation is used to modify the magnesium alloy surface in aqueous electrolytes,allowing strontium, calcium, and phosphorus to be incorporated into the coating. The thickness, composition, morphology and phase of this Sr–Ca–P containing coating are characterized by scanning electron microscopy equipped with energy dispersive X-ray spectrometer and X-ray diffraction. The in vitro and in vivo degradation of the coating is evaluated by immersion test, electrochemical test and implantation test. Moreover, the cytocompatibility is tested with osteoblast cell according to ISO 10993. The results show that Sr, Ca and P elements are incorporated into the oxide coating, and a refined structure with tiny discharging micro-pores is observed on the surface of the coating. The Sr–Ca–P coating possesses a better corrosion resistance in vitro and retards the degradation in vivo. Such coating is expected to have significant medical applications on orthopedic implants and bone repair materials. | Junjie Han Peng Wan Yu Sun Zongyuan Liu Xinmin Fan Lili Tan Ke Yang | 2016 | Journal of Materials Science & Technology2016，32，3： | 8 |

| 7 | Study on Quantum Trust Model Based on Node Trust Evaluation显示文摘Trust is the premise and foundation of secure communication,no matter in the quantum communication or classical communication.In fact,the existing quantum secure communication protocols and technologies are implicitly related to trust;or assume some trust premise in advance;or create or obtain a trust relationship.This paper studies on quantum trust model using node trust evaluation based on author’s own research achievements.We introduce the trust management into quantum communication network to build secure trusted quantum communication network based on evaluating the trust values of nodes,which are used to evaluate the reliability of each user.We put forward a scheme of quantum trust model based on node trust evaluation,and describe the thought and process of trust evaluation in detail based on the principles of quantum entanglement and quantum teleportation.We analyze the feasibility and safety of this scheme,which provides a new thinking and method for establishing a credible secure quantum communication network. | ZHANG Shibin XIE Zhihai YIN Yifen CHANG Yan SHENG Zhiwei YAN Lili WANG Haichun HAN Guihua HUANG Yuanyuan WAN Guogen | 2017 | Chinese Journal of Electronics2017，26，3： | 5 |
| 8 | Eocene Basins on the SE Tibetan Plateau: Markers of Minor Offset along the Xuelongshan–Diancangshan–Ailaoshan Structural System显示文摘The offset of geological bodies provides robust evidence of displacement along a fault or ductile shear zone. The amount of displacement along the Xuelongshan–Diancangshan–Ailaoshan structural system, southeastern Tibetan Plateau, is uncertain because of the lack of offset geological markers. This NNW–SSE-trending system is developed in three isolated metamorphic complexes and interjacent nonmetamorphosed rocks. They are expected to record similar post-Eocene strain, although their structural patterns should be distinct. Geological mapping in the area between the Xuelongshan and Diancangshan metamorphic complexes has revealed a small Eocene basin, the Madeng Basin, located to the west of the structural system. The sedimentary and volcanic successions of the Madeng Basin are comparable to those of the Jianchuan Basin, which is located to the east of the structural system. Zircon U–Pb geochronological and bulk geochemical data demonstrate that the volcanic rocks of both basins formed during 37–34 Ma and share the same geochemical features. These data suggest that the Madeng and Jianchuan basins previously constituted a single basin, with the distribution of high-K volcanic rocks in the basins defining an ENE–WSW-trending volcanic belt that shows a limited dextral offset of ≤20 km across the Xuelongshan–Diancangshan–Ailaoshan structural system. Therefore, the northern segment of the structural system records no evidence of large-scale lateral movement/displacement. The results suggest that the Indochina block, which is bounded by the Xuelongshan–Diancangshan–Ailaoshan structural system to the east and the Sagaing Fault to the west, has not extruded southward as a whole but rather has been deformed by pervasive crustal shortening. | LIAO Cheng YANG Tiannan XUE Chuandong LIANG Mingjuan XIN Di XIANG Kun JIANG Lili SHI Pengliang ZHU Wenbin WAN Liangchun TANG Jing YU Jing WU Pinglei | 2020 | Acta Geologica Sinica(English Edition)2020，94，4： | 5 |
| 9 | Regulation of bile acid receptor activity显示文摘Many receptors can be activated by bile acids(BAs)and their derivatives.These include nuclear receptors farnesoid X receptor(FXR),pregnane X receptor(PXR),and vitamin D receptor(VDR),as well as membrane receptors Takeda G protein receptor 5(TGR5),sphingosine-1-phosphate receptor 2(S1PR2),and cholinergic receptor muscarinic 2(CHRM2).All of them are implicated in the development of metabolic and immunological diseases in response to endobiotic and xenobiotic exposure.Because epigenetic regulation is critical for organisms to adapt to constant environmental changes,this review article summarizes epigenetic regulation as well as post-transcriptional modification of bile acid re-ceptors.In addition,the focus of this review is on the liver and digestive tract although these receptors may have effects on other organs.Those regulatory mechanisms are implicated in the disease process and critically important in uncovering innovative strategy for prevention and treatment of metabolic and immunological diseases. | Yu-Jui Yvonne Wan Lili Sheng | 2018 | Liver Research2018，2，4： | 4 |
| 10 | Biodegradable magnesium pins enhanced the healing of transverse patellar fracture in rabbits显示文摘Displaced fractures of patella often require open reduction surgery and internal fixation to restore the extensor continuity and articular congruity.Fracture fixation with biodegradable magnesium(Mg)pins enhanced fracture healing.We hypothesized that fixation with Mg pins and their degradation over time would enhance healing of patellar fracture radiologically,mechanically,and histologically.Transverse patellar fracture surgery was performed on thirty-two 18-weeks old female New Zealand White Rabbits.The fracture was fixed with a pin made of stainless steel or pure Mg,and a figure-of-eight stainless steel band wire.Samples were harvested at week 8 or 12,and assessed with microCT,tensile testing,microindentation,and histology.Microarchitectural analysis showed that Mg group showed 12%higher in the ratio of bone volume to tissue volume at week 8,and 38.4%higher of bone volume at week 12.Tensile testing showed that the failure load and stiffness of Mg group were 66.9%and 104%higher than the control group at week 8,respectively.At week 12,Mg group was 60.8%higher in ultimate strength than the control group.Microindentation showed that,compared to the Control group,Mg group showed 49.9%higher Vickers hardness and 31%higher elastic modulus at week 8 and 12,respectively.At week 12,the new bone of Mg group remodelled to laminar bone,but those of the control group remained woven bone-like.Fixation of transverse patellar fracture with Mg pins and its degradation enhanced new bone formation and mechanical properties of the repaired patella compared to the Control group. | Dick Ho Kiu Chow Jiali Wang Peng Wan Lizhen Zheng Michael Tim Yun Ong Le Huang Wenxue Tong Lili Tan Ke Yang Ling Qin | 2021 | Bioactive Materials2021，6，11： | 3 |
| 11 | An alternative magnesium-based root canal disinfectant: Preliminary study of its efficacy against Enterococcus faecalis and Candida albicans in vitro显示文摘Organisms invading root canal systems result in serious pulpal and periapical disease. To eliminate microorganisms and restrain secondary infections, dental materials with antibacterial properties are urgently needed in endodontics. Magnesium is considered as a promising biodegradable and biocompatible implant material. However, there are barely researches about its application in endodontic therapy. This work investigated the in vitro efficacy of magnesium powder against Enterococcus faecalis and Candida albicans compared with a common disinfectant, calcium hydroxide. With Calcium hydroxide served as a comparison it demonstrated the qualified antibacterial and anti-fungus properties of Mg as root canal disinfectant due to its high alkalinity of degradation, and the antimicrobial efficacy enhanced with the decreasing powder size. | Lin Zhu Peng Wan Jiaohong Duan Lili Tan Ke Yang | 2014 | Progress in Natural Science:Materials International2014，24，5： | 3 |
| 12 | Safety assessment method of performance-based navigation airspace planning显示文摘The paper introduces a computational model of airspace conflict risk in the hierarchy of performance-based navigation(PBN) airspace operation and combines it with air traffic controller(ATC) workload to propose a method for safety assessment of PBN airspace operational planning.Capacity probability distribution is employed to depict airspace capacity in uncertain weather,errors of deviating from nominal PBN track are taken into consideration,and the stochastic process based on Gaussian distribution is used to depict random aircraft motion according to airspace PBN specification,so as to build an airspace conflict risk computational model in corresponding capacity scenario.Guangzhou No.15 sector is chosen for simulation validation.The analysis results suggest that 60%of ATC workload is corresponding to sector traffic flow of 31 aircraft/h and airspace risk of 0.018conflict/h,while 70%of ATC workload is corresponding to sector traffic flow of 35 aircraft/h and airspace risk of 0.03 conflict/h.As air traffic flow increases,both airspace conflict risk value and ATC workload will increase,resulting in reduction of airspace safety,though their increasing magnitudes differ with different capacity scenarios.The safety assessment method enables effective quantization of safety with regard to airspace operational planning strategy,and benefits the development of optimal operational scheme that balances risk with capacity demand. | Yong Tian Lili Wan Chun-hung Chen Ye Yang | 2015 | Journal of Traffic and Transportation Engineering(English Edition)2015，2，5： | 3 |
| 13 | Green Aircraft Taxiing Strategy Based on Multi-scenario Joint Optimization显示文摘The issue of green aircraft taxiing under various taxi scenarios is studied to improve the efficiency of aircraft surface operations and reduce environmental pollution around the airport from aircraft emissions.A green aircraft taxi programming model based on multi-scenario joint optimization is built according to airport surface network topology modeling by analyzing the characteristics of aircraft operations under three different taxiing scenarios:all-engine taxi,single-engine taxi,and electronic taxi.A genetic algorithm is also used in the model to minimize fuel consumption and pollutant emissions.The Shanghai Pudong International Airport is selected as a typical example to conduct a verification analysis.Compared with actual operational data,the amount of aircraft fuel consumption and gas emissions after optimization are reduced significantly through applying the model.Under an electronic taxiing scenario,fuel consumption can be lowered by 45.3%,and hydrocarbon(HC)and carbon dioxide(CO)emissions are decreased by 80%.The results show that a green aircraft taxiing strategy that integrates taxiway optimization and electronic taxiing can effectively improve the efficiency of airport operations and reduce aircraft pollution levels in an airport′s peripheral environment. | Wan Lili Hu Minghua Tian Yong Ye Bojia | 2016 | Transactions of Nanjing University of Aeronautics and Astronautics2016，33，2： | 3 |
| 14 | Low intensity near-infrared light promotes bone regeneration via circadian clock protein cryptochrome 1显示文摘Bone regeneration remains a great clinical challenge. Low intensity near-infrared(NIR) light showed strong potential to promote tissue regeneration, offering a promising strategy for bone defect regeneration. However, the effect and underlying mechanism of NIR on bone regeneration remain unclear. We demonstrated that bone regeneration in the rat skull defect model was significantly accelerated with low-intensity NIR stimulation. In vitro studies showed that NIR stimulation could promote the osteoblast differentiation in bone mesenchymal stem cells(BMSCs) and MC3T3-E1 cells, which was associated with increased ubiquitination of the core circadian clock protein Cryptochrome 1(CRY1) in the nucleus. We found that the reduction of CRY1 induced by NIR light activated the bone morphogenetic protein(BMP) signaling pathways, promoting SMAD1/5/9 phosphorylation and increasing the expression levels of Runx2 and Osterix. NIR light treatment may act through sodium voltage-gated channel Scn4a, which may be a potential responder of NIR light to accelerate bone regeneration. Together, these findings suggest that low-intensity NIR light may promote in situ bone regeneration in a CRY1-dependent manner, providing a novel, efficient and non-invasive strategy to promote bone regeneration for clinical bone defects. | Jinfeng Peng Jiajia Zhao Qingming Tang Jinyu Wang Wencheng Song Xiaofeng Lu Xiaofei Huang Guangjin Chen Wenhao Zheng Luoying Zhang Yunyun Han Chunze Yan Qian Wan Lili Chen | 2022 | International Journal of Oral Science2022，14，4： | 2 |
| 15 | Synaptic development of layer V pyramidal neurons in the prenatal human prefrontal neocortex: a Neurolucida-aided Golgi study显示文摘The prefrontal neocortex is involved in many high cognitive functions in humans.Deficits in neuronal and neurocircuitry development in this part of the cerebrum have been associated with various neuropsychiatric disorders in adolescents and adults.There are currently little available data regarding prenatal dendrite and spine formation on projecting neurons in the human prefrontal neocortex.Previous studies have demonstrated that Golgi silver staining can identify neurons in the frontal lobe and visual cortex in human embryos.In the present study,five fetal brains,at 19,20,26,35,and 38 gestational weeks,were obtained via the body donation program at Xiangya School of Medicine,Central South University,China.Golgi-stained pyramidal neurons in layer V of Brodmann area 46 in fetuses were quantitatively analyzed using the Neurolucida morphometry system.Results revealed that somal size,total dendritic length,and branching points of these neurons increased from 26 to 38 gestational weeks.There was also a large increase in dendritic spines from 35 to 38 gestational weeks.These findings indicate that,in the human prefrontal neocortex,dendritic growth in layer V pyramidal neurons occurs rapidly during the third trimester of gestation.The use of human fetal brain tissue was approved by the Animal Ethics Committee of Xiangya School of Medicine,Central South University,China(approval No.2011-045)on April 5,2011. | Li-Xin He Lily Wan Wei Xiang Jian-Ming Li An-Hua Pan Da-Hua Lu | 2020 | Neural Regeneration Research2020，15，8： | 2 |

| 17 | Chemotherapy initiation with single-course methotrexate alone or combined with dactinomycin versus multi-course methotrexate for low-risk gestational trophoblastic neoplasia: a multi-centric randomized clinical trial显示文摘We aimed to evaluate the effectiveness and safety of single-course initial regimens in patients with low-risk gestational trophoblastic neoplasia(GTN).In this trial (NCT01823315),276 patients were analyzed.Patients were allocated to three initiated regimens:single-course methotrexate(MTX),single-course MTX+dactinomycin(ACTD),and multi-course MTX(control arm).The primary endpoint was the complete remission(CR)rate by initial drug(s).The primary CR rate was 64.4%with multi-course MTX in the control arm.For the single-course MTX arm,the CR rate was 35.8%by one course;it increased to 59.3%after subsequent multi-course MTX,with non-inferiority to the control(difference-5.1%,95%confidence interval(CI)-19.4%to 9.2%,P=0.014).After further treatment with multi-course ACTD,the CR rate(93.3%)was similar to that of the control(95.2%,P=0.577).For the single-course MTX+ACTD arm,the CR rate was 46.7%by one course,which increased to 89.1%after subsequent multi-course,with non-inferiority(difference 24.7%,95%CI 12.8%-36.6%,P<0.001)to the control.It was similar to the CR rate by MTX and further ACTD in the control arm(89.1%vs.95.2%,P=0.135).Four patients experienced recurrence,with no death,during the 2-year follow-up.We demonstrated that chemotherapy initiation with single-course MTX may be an alternative regimen for patients with low-risk GTN. | Lili Chen Ling Xi Jie Jiang Rutie Yin Pengpeng Qu Xiuqin Li Xiaoyun Wan Yaxia Chen Dongxiao Hu Yuyan Mao Zimin Pan Xiaodong Cheng Xinyu Wang Qingli Li Danhui Weng Xi Zhang Hong Zhang Quanhong Ping Xiaomei Liu Xing Xie Beihua Kong Ding Ma Weiguo Lu | 2022 | Frontiers of Medicine2022，16，2： | 2 |
| 18 | Relationship between Expression of CEA,E-cadherin and Liver Metastasis in Colorectal Cancer显示文摘OBJECTIVE To investigate the expression of E-cadherin andCEA in serum in colorectal carcinoma and their relationship withliver metastasis.METHODS CEA level was measured post-operativelyby radioimmunoassay of 60 patients with colorectal cancer.Immunohistochemical analysis was used to evaluate theexpression of E-cadherin.RESULTS In liver metastasis group,24 patients (24/26,92.3%)were high level of CEA,but only 9 patients in non-liver metastasisgroup.The difference is significant (P=0.004).Expression ofE-cadherin significantly correlated with differentiation,but wasnot associated with Tstage or N stage.Liver metastatic rate innegative expression was higher than that in positive expression.And the survival analysis showed that time of liver metastasis wassignificant different in two groups (P<0.05).CONCLUSION The expression of CEA in serum can be usedto predict liver mestatasis of colorectal cancer after operation.E-cadherin,associated with tumor differentiation,is also a hopefulindicator for the prediction of liver metastasis in patients withcolorectal cancer. | Ning Li Xiaobing Chen Xiangbin Wan Suxia Luo Lili Han Mengqiang Zhou Dengwen Yin Li Zhang | 2008 | Chinese Journal of Clinical Oncology2008，5，6： | 2 |
| 19 | Synthetic poly-dioxolane as universal solid electrolyte interphase for stable lithium metal anodes显示文摘Lithium (Li) metal is a promising anode for the next generation high-energy–density batteries. However, the growth of Li dendrites, low coulombic efficiency and dramatic volume change limit its development. Here, we report a new synthetic poly-dioxolane (PDOL) approach to constructing an artificial 'elastic' SEI to stabilize the Li/electrolyte interface and the Li deposition/dissolution behavior in a variety of electrolytes. By coating PDOL with optimized molecular weights and synthetic routes on Li metal anode, the 'elastic' SEI layer could be maintained on top of the Li metal anode to accommodate the Li deposition/dissolution. No dendrite formation was observed during the cycling process, and the interfacial side reactions were reduced significantly. Consequently, we successfully achieved 330 cycles with a CE of 98.4% in ether electrolytes and 90 cycles with a CE of 94.3% in carbonate electrolytes. Simultaneously, the Li-metal batteries with LiFePO_(4) as cathodes also exhibited improved cycling performance. This strategy could promote the development of dendrite-free metal anodes toward high-performance Li-metal batteries. | Tao Chen Haiping Wu Jing Wan Mengxue Li Yucheng Zhanga Lin Sun Yuncong Liu Lili Chen Rui Wen Chao Wang | 2021 | Journal of Energy Chemistry2021，30，11： | 1 |
