| 1 | Effect of artificial aeration on the performance of vertical-flow constructed wetland treating heavily polluted river water显示文摘Three lab-scale vertical-flow constructed wetlands(VFCWs),including the non-aerated(NA),intermittently aerated(IA) and continuously aerated(CA) ones,were operated at different hydraulic loading rates(HLRs) to evaluate the effect of artificial aeration on the treatment efficiency of heavily polluted river water.Results indicated that artificial aeration increased the dissolved oxygen(DO) concentrations in IA and CA,which significantly favored the removal of organic matter and NH 4 +-N.The DO grads caused by intermittent aeration formed aerobic and anoxic regions in IA and thus promoted the removal of total nitrogen(TN).Although the removal efficiencies of COD Cr,NH 4 +-N and TN in the three VFCWs all decreased with an increase in HLR,artificial aeration enhanced the reactor resistance to the fluctuation of pollutant loadings.The maximal removal efficiencies of COD Cr,NH 4 +-N and total phosphorus(TP)(i.e.,81%,87% and 37%,respectively) were observed in CA at 19 cm/day HLR,while the maximal TN removal(i.e.,57%) was achieved in IA.Although the improvement of artificial aeration on TP removal was limited,this study has demonstrated the feasibility of applying artificial aeration to VFCWs treating polluted river water,particularly at a high HLR. | Huiyu Dong Zhimin Qiang Tinggang Li Hui Jin Weidong Chen | 2012 | Journal of Environmental Sciences2012，24，4： | 38 |
| 2 | Pulse changes in patients with cervical spondylosis before and after acupuncture treatment显示文摘OBJECTIVE: To study changes in pulse diagram parameters(PDP) in patients with cervical spondylosis(CS) before and after acupuncture treatment, explore the characteristics of PDP and the relationship between PDP changes and therapeutic effectiveness, and provide evidence for outcome prediction and objective evaluation of CS treatment before and after acupuncture treatment.METHODS: Patients with CS were treated with acupuncture and measured with a pulse acquisition device based on image(PADBI) before the first and after the tenth acupuncture sessions. Changes in PDP from before until after the acupuncture sessions and patient impressions were analyzed to judge the effect of acupuncture treatment for.RESULTS: The PDP values in effective patients were closer to normal values. This indicated that Qi stagnation and blood stasis of the patients was improved. The PDP changes from before to after the first acupuncture treatment were more obvious than those from before to after the tenth acupuncture treatment. This result indicates that the speed of symptom improvement decreased significantly after several acupuncture courses. Analysis of correlation between efficacy and PDP showed that the changes in PDP in five patients was abnormal,which mainly manifested as values of h1, u, p, Pp,and t1, and no significant changes or differences were increased with standard values. This indicated that the symptoms of CS were not improved in these patients.CONCLUSION: PADBI can provide evidence for outcome prediction of acupuncture treatment in patients with CS. PADBI can provide evidence for objective evaluation of acupuncture treatment of CS. | Zhang Huiyu Guo Minfang Lu Xiaozuo | 2016 | Journal of Traditional Chinese Medicine2016，36，1： | 34 |
| 3 | Sonodynamic therapy(SDT): a novel strategy for cancer nanotheranostics显示文摘Sonodynamic therapy(SDT) is a promising non-invasive therapeutic modality. Compared to photo-inspired therapy, SDT provides many opportunities and benefits, including deeper tissue penetration, high precision, less side effects, and good patient compliance. Thanks to the facile engineerable nature of nanotechnology, nanoparticles-based sonosensitizers exhibit predominant advantages, such as increased SDT efficacy, binding avidity, and targeting specificity. This review aims to summarize the possible mechanisms of SDT, which can be expected to provide the theoretical basis for SDT development in the future. We also extensively discuss nanoparticle-assisted sonosensitizers to enhance the outcome of SDT. Additionally, we focus on the potential strategy of combinational SDT with other therapeutic modalities and discuss the limitations and challenges of SDT toward clinical applications. | Xueting Pan Hongyu Wang Shunhao Wang Xiao Sun Lingjuan Wang Weiwei Wang Heyun Shen Huiyu Liu | 2018 | Science China(Life Sciences)2018，61，4： | 26 |
| 4 | An optimization strategy of controlled electric vehicle charging considering demand side response and regional wind and photovoltaic显示文摘Renewable energy,such as wind and photovoltaic(PV),produces intermittent and variable power output.When superimposed on the load curve,it transforms the load curve into a‘load belt’,i.e.a range.Furthermore,the large scale development of electric vehicle(EV)will also have a significant impact on power grid in general and load characteristics in particular.This paper aims to develop a controlled EV charging strategy to optimize the peak-valley difference of the grid when considering the regional wind and PV power outputs.The probabilistic model of wind and PV power outputs is developed.Based on the probabilistic model,the method of assessing the peak-valley difference of the stochastic load curve is put forward,and a two-stage peak-valley price model is built for controlled EV charging.On this basis,an optimization model is built,in which genetic algorithms are used to determine the start and end time of the valley price,as well as the peak-valley price.Finally,the effectiveness and rationality of the method are proved by the calculation result of the example. | Hong LIU Pingliang ZENG Jianyi GUO Huiyu WU Shaoyun GE | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，2： | 23 |
| 5 | Identifying Materials of Photographic Images and Photorealistic Computer Generated Graphics Based on Deep CNNs显示文摘Currently,some photorealistic computer graphics are very similar to photographic images.Photorealistic computer generated graphics can be forged as photographic images,causing serious security problems.The aim of this work is to use a deep neural network to detect photographic images(PI)versus computer generated graphics(CG).In existing approaches,image feature classification is computationally intensive and fails to achieve realtime analysis.This paper presents an effective approach to automatically identify PI and CG based on deep convolutional neural networks(DCNNs).Compared with some existing methods,the proposed method achieves real-time forensic tasks by deepening the network structure.Experimental results show that this approach can effectively identify PI and CG with average detection accuracy of 98%. | Qi Cui Suzanne McIntosh Huiyu Sun | 2018 | Computers, Materials & Continua2018，，5： | 12 |
| 6 | The in vitro effect of lipopolysaccharide on proliferation, inflammatory factors and antioxidant enzyme activity in bovine mammary epithelial cells显示文摘Lipopolysaccharide(LPS) was selected as a stimulus to investigate its effect on cell viability and oxidative stress in bovine mammary epithelial cells(BMEC) by detecting the cell relative growth rate(RGR),antioxidant indicators and inflammatory factors. This information was used to provide the theoretical basis for the establishment of a LPS-induced oxidative damage model. The experiment was divided into two parts. The first part used a two-factor experimental design to determine the appropriate incubation time of LPS by detecting the RGR. The third-passage BMEC were divided into 24 groups with six replicates in each group. The first factor was LPS concentration, which was 0(control), 0.1,1.0 and 10.0 μg/mL;the second factor was LPS incubation time(2,4, 6, 8,12 and 24 h). The optimum LPS incubation time was6 h according to the results of the first part of the experiment. The second part of the experiment was conducted using a single-factor experimental design, and the third-passage cells were divided into four groups with six replicates in each group. The cells were incubated with culture medium containing different concentrations of LPS(0 [control], 0.1, 1.0 and 10.0 μg/mL) for 6 h to select the appropriate concentration of LPS to measure the antioxidant indicators and inflammatory factors. The results showed the RGR was significantly reduced as the concentration of LPS and the incubation time increased;the interaction between concentration and incubation time was also significant. The cells treated with0.1 μg/mL of LPS for 6 h had no significant difference in the activities of glutathione peroxidase(GPx) and superoxide dismutase(SOD)(P > 0.05) compared with the cells in the control group. On the contrary,catalase(CAT) activity and malondialdehyde(MDA) content were markedly lower and higher, respectively, in the 0.1 μg/mL LPS-treated group for 6 h compared with the control group(P < 0.05). The activities of GPx, CAT and SOD in the BMEC treated with 1.0 or 10.0 μg/mL of LPS were significantly lower compared with the cells treated with 0.1 μg/mL of LPS and cells in the control group after 6 h of incubation; however, the opposite trend was detected in MDA content. There was no significant(P > 0.05)difference between the 10.0 and 1.0 μg/mL LPS-treated groups. Compared with the control group,interleukin-1, interleukin-6 and nitric oxide concentrations and the activity of inducible nitric oxide synthase in the 0.1 μg/mL LPS-treated group significantly increased(P < 0.0001), but the levels of tumour necrosis factor did not significantly change(P > 0.05). All of observed indicators were higher in the 1.0 and 10.0 μg/mL LPS-treated groups(P < 0.0001) compared with the other groups, but there was no significant(P> 0.05) difference between the 1.0 and 10.0 μg/mL LPS-treated groups. The results indicated that a concentration of 1.0 μg/mL of LPS and an incubation time of 6 h were the optimum conditions necessary to induce oxidative stress in the BMEC and establish a model for oxidative damage. | Huiyu Shi Yongmei Guo Yang Liu Binlin Shi Xiaoyu Guo Lu Jin Sumei Yan | 2016 | Animal Nutrition2016，，2： | 11 |

| 9 | Combination of iTRAQ proteomics and RNA-seq transcriptomics reveals multiple levels of regulation in phytoplasma-infected Ziziphus jujuba Mill显示文摘Jujube witches’broom(JWB)is caused by infection with a phytoplasma.A multi-omics approach was taken during graft infection of jujube by JWB-infected scion through the analysis of the plant transcriptome,proteome and phytohormone levels.A high number of differentially expressed genes(DEGs)were identified 37 weeks after grafting(WAG),followed by observation of typical symptoms of JWB at 48 WAG.At 37 WAG,the majority of the upregulated DEGs and differentially expressed proteins(DEPs)were related to flavonoid biosynthesis,phenylalanine metabolism and phenylpropanoid biosynthesis.Two of the four upregulated proteins were similar to jasmonate-induced protein-like.Among the downregulated genes,the two most populated GO terms were plant–pathogen interaction and plant hormone signal transduction(mainly for tryptophan metabolism).Moreover,phytoplasma infection resulted in reduced auxin content and increased jasmonate content,indicating that auxin and jasmonic acid have important roles in regulating jujube responses during the first and second stages of phytoplasma infection.At 48 WAG,the two largest groups of upregulated genes were involved in phenylpropanoid biosynthesis and flavonoid biosynthesis.Both genes and proteins involved in carbon metabolism and carbon fixation in photosynthetic organisms were downregulated,indicating that photosynthesis was affected by the third stage of phytoplasma infection. | Xia Ye Huiyu Wang Peng Chen Bing Fu Mengyang Zhang Jidong Li Xianbo Zheng Bin Tan Jiancan Feng | 2017 | Horticulture Research2017，4，1： | 9 |
| 10 | Ultrasmall Fe-doped carbon dots nanozymes for photoenhanced antibacterial therapy and wound healing显示文摘Pathogenic bacteria pose a devastating threat to public health.However,because of the growing bacterial antibiotic resistance,there is an urgent need to develop alternative antibacterial strategies to the established antibiotics.Herein,iron-doped carbon dots(Fe-CDs,~3 nm)nanozymes with excellent photothermal conversion and photoenhanced enzyme-like properties are developed through a facile one-pot pyrolysis approach for synergistic efficient antibacterial therapy and wound healing.In particular,Fe doping endows CDs with photoenhanced peroxidase(POD)-like activity,which lead to the generation of heat and reactive oxygen species(ROS)for Gram-positive and Gram-negative bacteria killing.This study demonstrates Fe-CDs have significant wound healing efficiency of Fe-CDs by preventing infection,promoting fibroblast proliferation,angiogenesis,and collagen deposition.Furthermore,the ultrasmall size of Fe-CDs possesses good biocompatibility favoring clinical translation.We believe that the nanozyme-mediated therapeutic platform presented here is expected to show promising applications in antibacterial. | Yunhang Liu Bolong Xu Mingzhu Lu Shanshan Li Juan Guo Fangzhou Chen Xiaolu Xiong Zhe Yin Huiyu Liu Dongsheng Zhou | 2022 | Bioactive Materials2022，7，6： | 7 |
| 11 | Responses of Spatial-temporal Variation of Karst Ecosystem Service Values to Landscape Pattern in Northwest of Guangxi,China显示文摘The responses of spatiotemporal variation of ecosystem service values (ESVs) to landscape pattern from 1985 to 2005 in a typical Karst area of the northwest Guangxi Zhuang Autonomous Region,China,were examined us-ing remote sensing and geographic information system techniques in this paper.The total ecosystem service values de-clined significantly from 1985 to 1990,and then increased slowly from 1990 to 2005,almost equaled to the 1985 level.The ecosystem service values tended to decline from the west to the east and from mountainous regions to peak-cluster depression areas in 1985,1990,2000 and 2005 respectively.During the period from 1985 to 2005,the ecosystem ser-vice values have increased in the middle and eastern parts of the study area.Landscape pattern indices,such as total area,largest patch index,contagion,aggregative index,effective mesh and proportion of like adjacencies,are significantly correlated with ecosystem service values.This suggests that ecosystem service values tend to increase with the growth of patch area and patch connectivity.However,there are negative correlations between ecosystem service values and landscape pattern indices,such as division index and patch richness.It indicates that ecosystem service values decrease with patch fragmentation and patch size shrinkage.The ecosystem conditions in the typical Karst area have been improved because of the control measures of rocky desertification.It is important to protect key landscape types,such as woodland,shrub and grassland,and to increase patch size and connectivity to avoid further fragmentation.Furthermore,it is necessary to reduce disturbances to ensure the growth of ecosystem service values and to facilitate the sustainable development in this region. | ZHANG Mingyang WANG Kelin LIU Huiyu ZHANG Chunhua | 2011 | Chinese Geographical Science2011，21，4： | 6 |
| 12 | Rational design of novel ultra-small amorphous Fe_(2)O_(3)nanodots/graphene heterostructures for all-solid-state asymmetric supercapacitors显示文摘Constructing graphene-based heterostructures with large interfacial area is an efficient approach to enhance the electrochemical performance of supercapacitors but remains great challenges in their synthesis.Herein,a novel ultra-small amorphous Fe_(2)O_(3)nanodots/graphene heterostructure(a-Fe_(2)O_(3)NDs/RGO)aerogel was facilely synthesized via excessive metal-ion-induced self-assembly and subsequent calcination route using Prussian blue/graphene oxide(PB/GO)composite aerogel as precursors.The deliberately designed a-Fe_(2)O_(3)NDs/RGO heterostructure offers a highly interconnected porous conductive network,large heterostructure interfacial area,and plenty of accessible active sites,greatly facilitating the electron transfer,electrolyte diffusion,and pseudocapacitive reactions.The obtained a-Fe_(2)O_(3)NDs/RGO aerogel could be used as flexible free-standing electrodes after mechanical compression,which exhibited a significantly enhanced specific capacitance of 347.4 F·g^(-1)at 1 A·g^(-1),extraordinary rate capability of 184 F·g^(-1)at 10 A·g^(-1),and decent cycling stability.With the as-prepared a-Fe_(2)O_(3)NDs/RGO as negative electrodes and the Co_(3)O_(4)NDs/RGO as positive electrodes,an all-solid-state asymmetric supercapacitor(a-Fe_(2)O_(3)NDs/RGO//Co_(3)O_(4)NDs/RGO asymmetric supercapacitor(ASC))was assembled,which delivered a high specific capacitance of 69.1 F·g^(-1)at 1 A·g^(-1)and an impressive energy density of 21.6 W·h·k·g^(-1)at 750 W·k·g^(-1),as well as good cycling stability with a capacity retention of 94.3%after 5,000 cycles.This work provides a promising avenue to design high-performance graphene-based composite electrodes and profound inspiration for developing advanced flexible energy-storage devices. | Chenxiao Wu Zhifang Zhang Zhonghui Chen Zuimin Jiang Huiyu Li Haijing Cao Yongsheng Liu Yanyan Zhu Zebo Fang Xiangrong Yu | 2021 | Nano Research2021，14，4： | 6 |
| 13 | Smoking Behavior Among Secondary School Students--China, 2021显示文摘Summary What is already known about this topic?In 2019,China CDC conducted the National Youth Tobacco Survey among secondary school students,and the prevalence rates of ever,current,and frequent smoking were 17.9%,5.9%,and 1.8%,respectively.What is added by this report?The prevalence rate of cigarette use in males decreased largely from 2019 to 2021 in China,while it increased in 18 provincial-level administrative divisions(PLADs)for females.The tobacco control situation remains challenging among vocational senior high school(VSHS)students.Significant geographical disparities existed in cigarette use.What are the implications for public health practice?Targeted tobacco control policies aimed at VSHS students are needed,specifically those PLADs with higher smoking rates.Additionally,close attention should be paid to female smokers. | Xinying Zeng Xinbo Di Shiwei Liu Huiyu Xie Zida Meng Lin Xiao | 2022 | China CDC weekly2022，4，21： | 5 |
| 14 | Spleen-Yang-deficiency patients with polycystic ovary syndrome have higher levels of visfatin显示文摘OBJECTIVE:To study serum visfatin levels in women with polycystic ovary syndrome(PCOS)grouped by Traditional Chinese Medicine(TCM)patterns.To study the correlations of serum visfatin levels with homeostatic model assessment insulin resistance(HOMA-IR),fasting plasma glucose(FPG),fasting insulin(FINS),body mass index(BMI),testosterone(T),total cholesterol(TC),and triglycerides(TG).METHODS:Two hundred and twelve PCOS patients were placed into the following TCM pattern subgroups:Kidney-Yang deficiency(KYD)group,Spleen-Yang deficiency(SYD)group,stagnant Liver-Qi transforming into heat(SLQTH)group,and Kidney-Yin deficiency(KYIND)group.The correlations between serum visfatin levels and HOMA-IR,FPG,FINS,BMI,T,TC,andTG were analyzed.RESULTS:Of all patients with PCOS,there were 82in the KYD group(38.6%),67 in the SYD group(31.6%),37 in the SLQTH group(17.5%),and 26 in the KYIND group(12.3%).Visfatin levels in all PCOS subgroups were higher than those in the control group(P<0.01 or P<0.05).Among these subgroups,the visfatin levels in the SYD group were significantly higher than those in the other three TCM pattern groups(P<0.05).There were no statistical differences among the remaining three pattern groups.The levels of BMI,FINS,HOMA-IR,T,and TG were significantly higher in all subgroups than those in the control group(P<0.05).There were no significant differences in FPG and TC between all PCOS subgroups and the control group(P>0.05).The SYD group had higher levels of FINS and HOMA-IR compared with the KYD,SLQTH,and KYIND groups(P<0.05).In all subgroups,after controlling for BMI,TG,TC,and age,visfatin was positively correlated with FINS(r=0.197,P=0.015)and HOMA-IR(r=0.173,P=0.033),and was not correlated with T.CONCLUSION:KYD and SYD patterns are most common in PCOS patients.Increased visfatin is a common pathophysiologic manifestation in PCOS patients.The SYD group had the highest levels of visfatin,and visfatin was positively correlated with FINS and HOMA-IR. | Huijia Fu Yan Qiu Feng Wei Li Yang Min Xia Huiyu He | 2014 | Journal of Traditional Chinese Medicine2014，34，1： | 5 |
| 15 | High-yield preparation of robust gold nanoshells on silica nanorattles with good biocompatiblity显示文摘Although gold nanoshells are widely considered as one of the promising photothermal nanomaterials used for biomedicine, the high cost, low yield and poor stability severely limit their potential application in clinical trials.Herein, robust gold nanoshells on silica nanorattles(GSNs)were easily prepared in a high yield by an improved seedmediated method employing polyvinylpyrrolidone(PVP) as a stabilizing and capping agent. The present method is very simple, effective and reproducible and can well control the growth process of gold nanoshells. The as-prepared GSNs have a narrow size distribution(<10 % in standard deviation). Furthermore, the utilization rate of Au in the solution used for the growth of gold nanoshells increases by 70 %than that in previous method. The resultant GSNs have a good structural stability after placing over 6 months due to the protection of PVP. More importantly, in vivo and in vitro toxic studies indicate that the GSNs have good biocompatibility. We believe that our preparation method will remarkably promote the use of gold nanoshells for biomedicine. | Changhui Fu Chaofeng He Longfei Tan Shunhao Wang Lu Shang Linlin Li Xianwei Meng Huiyu Liu | 2016 | Science Bulletin2016，61，4： | 5 |
| 16 | Disinfection by-product(DBP) research in China:Are we on the track?显示文摘Disinfection by-products(DBPs) formed during water disinfection has drawn significant public concern due to its toxicity. Since the first discovery of the trihalomethanes in 1974,continued effort has been devoted on DBPs worldwide to investigate the formation mechanism, levels, toxicity and control measures in drinking water. This review summarizes the main achievements on DBP research in China, which included:(1) the investigation of known DBP occurrence in drinking water of China;(2) the enhanced removal of DBP precursor by water treatment process;(3) the disinfection optimization to minimize DBP formation;and(4) the identification of unknown DBPs in drinking water. Although the research of DBPs in China cover the whole formation process of DBPs, there is still a challenge in effectively controlling the drinking water quality risk induced by DBPs, an integrated research framework including chemistry, toxicology, engineering, and epidemiology is especially crucial. | Huiyu Dong Haifeng Zhang Yan Wang Zhimin Qiang Min Yang | 2021 | Journal of Environmental Sciences2021，33，12： | 4 |
| 17 | BpMADS12 gene role in lignin biosynthesis of Betula platyphylla Suk by transcriptome analysis显示文摘MADS-box transcription factors show highly diverse regulatory functions in a wide variety of organisms.In this study,we characterized a MADS-box gene(BpMADS12) from the white birch(Betula platyphylla Suk).This gene is a member of the suppressor of overexpression of CO 1/tomato MADS 3 class of MADS-box genes.We generated lines overexpressing BpMADS12 and found that these had higher levels of lignin compared to that observed in nontransgenic lines.Transcriptome analysis revealed numerous changes in gene expression patterns.In total,8794 differentially expressed genes were identified,including 5006 upregulated unigenes and 3788 downregulated unigenes in Bp MADS-overexpression lines.Differentially expressed genes involved in the pathways for lignin and brassinosteroid biosynthesis were significantly enriched and may have contributed to phenotypic changes.The results from a quantitative RT-PCR analysis were consistent those obtained with the transcriptome analysis.Our transcriptome analysis,in combination with measurement of lignin level,indicated that Bp MADS12 promotes lignin synthesis through regulation of key enzymes in response to brassinosteroid signaling.These results suggest that this MADS-box protein is crucial to all subsequent structural events and provide a good foundation for studies aiming to elucidate the developmental mechanisms underlying formation of wood. | Huiyu Li Yang Yang Zijia Wang Xiaohong Guo Feifei Liu Jing Jiang Guifeng Liu | 2016 | Journal of Forestry Research2016，27，5： | 4 |
| 18 | Analyzing Cross-domain Transportation Big Data of New York City with Semi-supervised and Active Learning显示文摘The majority of big data analytics applied to transportation datasets suffer from being too domain-specific,that is,they draw conclusions for a dataset based on analytics on the same dataset.This makes models trained from one domain(e.g.taxi data)applies badly to a different domain(e.g.Uber data).To achieve accurate analyses on a new domain,substantial amounts of data must be available,which limits practical applications.To remedy this,we propose to use semi-supervised and active learning of big data to accomplish the domain adaptation task:Selectively choosing a small amount of datapoints from a new domain while achieving comparable performances to using all the datapoints.We choose the New York City(NYC)transportation data of taxi and Uber as our dataset,simulating different domains with 90%as the source data domain for training and the remaining 10%as the target data domain for evaluation.We propose semi-supervised and active learning strategies and apply it to the source domain for selecting datapoints.Experimental results show that our adaptation achieves a comparable performance of using all datapoints while using only a fraction of them,substantially reducing the amount of data required.Our approach has two major advantages:It can make accurate analytics and predictions when big datasets are not available,and even if big datasets are available,our approach chooses the most informative datapoints out of the dataset,making the process much more efficient without having to process huge amounts of data. | Huiyu Sun Suzanne McIntosh | 2018 | Computers, Materials & Continua2018，，10： | 4 |
| 19 | Drilling Force and Temperature of Bone under Dry and Physiological Drilling Conditions显示文摘Many researches on drilling force and temperature have been done with the aim to reduce the labour intensiveness of surgery, avoid unnecessary damage and improve drilling quality. However, there has not been a systematic study of mid- and high-speed drilling under dry and physiological conditions(injection of saline). Furthermore, there is no consensus on optimal drilling parameters. To study these parameters under dry and physiological drilling conditions, pig humerus bones are drilled with medical twist drills operated using a wide range of drilling speeds and feed rates. Drilling force and temperature are measured using a YDZ-II01 W dynamometer and a NEC TVS-500 EX thermal infrared imager, respectively, to evaluate internal bone damage. To evaluate drilling quality, bone debris and hole morphology are observed by SEM(scanning electron microscopy). Changes in drilling force and temperature give similar results during drilling such that the value of each parameter peaks just before the drill penetrates through the osteon of the compact bone into the trabeculae of the spongy bone. Drilling temperatures under physiological conditions are much lower than those observed under dry conditions, while a larger drilling force occurs under physiological conditions than dry conditions. Drilling speed and feed rate have a significant influence on drilling force, temperature, bone debris and hole morphology. The investigation of the effect of drilling force and temperature on internal bone damage reveals that a drilling speed of 4500 r/min and a feed rate of 50 mm/min are recommended for bone drilling under physiological conditions. Drilling quality peaks under these optimal parameter conditions. This paper proposes the optimal drilling parameters under mid- and high-speed surgical drilling, considering internal bone damage and drilling quality, which can be looked as a reference for surgeons performing orthopedic operations. | XU Linlin WANG Chengyong JIANG Min HE Huiyu SONG Yuexian CHEN Hanyuan SHEN Jingnan ZHANG Jiayong | 2014 | Chinese Journal of Mechanical Engineering2014，27，6： | 3 |
