| 6 | Sustained Akt signaling in articular chondrocytes causes osteoarthritis via oxidative stress-induced senescence in mice显示文摘Osteoarthritis(OA) is an age-related disorder that is strongly associated with chondrocyte senescence. The causal link between disruptive PTEN/Akt signaling and chondrocyte senescence and the underlying mechanism are unclear. In this study, we found activated Akt signaling in human OA cartilage as well as in a mouse OA model with surgical destabilization of the medial meniscus.Genetic mouse models mimicking sustained Akt signaling in articular chondrocytes via PTEN deficiency driven by either Col2a1-Cre or Col2a1-Cre^(ERT2) developed OA, whereas restriction of Akt signaling reversed the OA phenotypes in PTEN-deficient mice.Mechanistically, prolonged activation of Akt signaling caused an accumulation of reactive oxygen species and triggered chondrocyte senescence as well as a senescence-associated secretory phenotype, whereas chronic administration of the antioxidant N-acetylcysteine suppressed chondrocyte senescence and mitigated OA progression in PTEN-deficient mice. Therefore,inhibition of Akt signaling by PTEN is required for the maintenance of articular cartilage. Disrupted Akt signaling in articular chondrocytes triggers oxidative stress-induced chondrocyte senescence and causes OA. | Jing Xie Jingting Lin Min Wei Yan Teng Qi He Guan Yang Xiao Yang | 2019 | Bone Research2019,7,3: | 8 |
| 7 | Cryogenic minimum quantity lubrication machining: from mechanism to application显示文摘Cutting fluid plays a cooling-lubrication role in the cutting of metal materials.However,the substantial usage of cutting fluid in traditional flood machining seriously pollutes the environment and threatens the health of workers.Environmental machining technologies,such as dry cutting,minimum quantity lubrication(MQL),and cryogenic cooling technology,have been used as substitute for flood machining.However,the insufficient cooling capacity of MQL with normal-temperature compressed gas and the lack of lubricating performance of cryogenic cooling technology limit their industrial application.The technical bottleneck of mechanical-thermal damage of difficult-to-cut materials in aerospace and other fields can be solved by combining cryogenic medium and MQL.The latest progress of cryogenic minimum quantity lubrication(CMQL)technology is reviewed in this paper,and the key scientific issues in the research achievements of CMQL are clarified.First,the application forms and process characteristics of CMQL devices in turning,milling,and grinding are systematically summarized from traditional settings to innovative design.Second,the cooling-lubrication mechanism of CMQL and its influence mechanism on material hardness,cutting force,tool wear,and workpiece surface quality in cutting are extensively revealed.The effects of CMQL are systematically analyzed based on its mechanism and application form.Results show that the application effect of CMQL is better than that of cryogenic technology or MQL alone.Finally,the prospect,which provides basis and support for engineering application and development of CMQL technology,is introduced considering the limitations of CMQL. | Mingzheng LIU Changhe LI Yanbin ZHANG Qinglong AN Min YANG Teng GAO Cong MAO Bo LIU Huajun CAO Xuefeng XU Zafar SAID Sujan DEBNATH Muhammad JAMIL Hafz Muhammad ALI Shubham SHARMA | 2021 | Frontiers of Mechanical Engineering2021,16,4: | 8 |
| 8 | Analysis of the effects of mass transfer on heat transfer in the process of moisture exchange across a membrane显示文摘A theoretical study was conducted to investigate the effects of mass transfer on heat transfer in the process of moisture exchange across a membrane and a mathematical model describing the heat transfer with consideration of the effect of mass transfer was developed.A dimensionless variable,ψi,which presents the degree to which the mass transfer affects the heat transfer,was proposed through theoretical analysis.With calculating of this dimensionless variable,the heat transfer coupled with mass transfer can be converted into a conventional heat transfer,making the heat transfer calculation simpler and more easily to understand.On the basis of theoretical analysis,the effects of mass transfer on heat transfer were numerically studied.The results show that,in the case that the temperature gradient and mass transfer are in the same direction,ψi is greater than unity,and the mass transfer acts to enhance the heat transfer;in the case that the temperature gradient and mass transfer are in opposite directions,ψi is less than unity,and the mass transfer works to hinder the heat transfer.When the mass flux is small,the effect of the mass transfer is weak.When the mass flux is large,the heat flux carried by the mass flux has a considerable impact on the heat flux,and ψi,deviates from unity significantly. | HU Teng MIN JingChun SONG YaoZu | 2010 | Chinese Science Bulletin2010,55,12: | 8 |
| 9 | Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes. | MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 无 | 2020 | Biomedical and Environmental Sciences2020,33,12: | 8 |
| 10 | Milling Force Model for Aviation Aluminum Alloy: Academic Insight and Perspective Analysis显示文摘Aluminum alloy is the main structural material of aircraft,launch vehicle,spaceship,and space station and is processed by milling.However,tool wear and vibration are the bottlenecks in the milling process of aviation aluminum alloy.The machining accuracy and surface quality of aluminum alloy milling depend on the cutting parameters,material mechanical properties,machine tools,and other parameters.In particular,milling force is the crucial factor to determine material removal and workpiece surface integrity.However,establishing the prediction model of milling force is important and difficult because milling force is the result of multiparameter coupling of process system.The research progress of cutting force model is reviewed from three modeling methods:empirical model,finite element simulation,and instantaneous milling force model.The problems of cutting force modeling are also determined.In view of these problems,the future work direction is proposed in the following four aspects:(1)high-speed milling is adopted for the thin-walled structure of large aviation with large cutting depth,which easily produces high residual stress.The residual stress should be analyzed under this particular condition.(2)Multiple factors(e.g.,eccentric swing milling parameters,lubrication conditions,tools,tool and workpiece deformation,and size effect)should be considered comprehensively when modeling instantaneous milling forces,especially for micro milling and complex surface machining.(3)The database of milling force model,including the corresponding workpiece materials,working condition,cutting tools(geometric figures and coatings),and other parameters,should be established.(4)The effect of chatter on the prediction accuracy of milling force cannot be ignored in thin-walled workpiece milling.(5)The cutting force of aviation aluminum alloy milling under the condition of minimum quantity lubrication(mql)and nanofluid mql should be predicted. | Zhenjing Duan Changhe Li Wenfeng Ding Yanbin Zhang Min Yang Teng Gao Huajun Cao Xuefeng Xu Dazhong Wang Cong Mao Hao Nan Li Gupta Munish Kumar Zafar Said Sujan Debnath Muhammad Jamil Hafiz Muhammad Ali | 2021 | Chinese Journal of Mechanical Engineering2021,34,1: | 7 |
| 11 | Tailoring bimodal grain structure of Mg-9Al-1Zn alloy for strength-ductility synergy:Co-regulating effect from coarse Al_(2)Y and submicron Mg_(17)Al_(12) particles显示文摘Grain boundary strengthening is an effective strategy for increasing mechanical properties of Mg alloys.However,this method offers limited strengthening in bimodal grain-structured Mg alloys due to the difficultly in increasing the volume fraction of fine grains while keeping a small grain size.Herein,we show that the volume fraction of fine grains(FGs,~2.5μm)in the bimodal grain structure can be tailored from~30 vol.%in Mg-9 Al-1 Zn(AZ91)to~52 vol.%in AZ91-1Y(wt.%)processed by hard plate rolling(HPR).Moreover,a superior combination of a high ultimate tensile strength(~405 MPa)and decent uniform elongation(~9%)is achieved in present AZ91-1Y alloy.It reveals that a desired bimodal grain structure can be tailored by the co-regulating effect from coarse Al_(2)Y particles resulting in inhomogeneous recrystallization,and dispersed submicron Mg_(17)Al_(12)particles depressing the growth of recrystallized grains.The findings offer a valuable insight in tailoring bimodal grain-structured Mg alloys for optimized strength and ductility. | Yong-Kang Li Min Zha Hai-Long Jia Si-Qing Wang Hongmin Zhang Xiao Ma Teng Tian Pinkui Ma Hui-Yuan Wang | 2021 | Journal of Magnesium and Alloys2021,9,5: | 6 |
| 12 | Correlation between Traditional Chinese Medicine symptom patterns and serum concentration of zinc,iron,copper and magnesium in patients with hepatitis B and associated liver cirrhosis显示文摘OBJECTIVE:To investigate the correlation between the patterns of Traditional Chinese Medicine(TCM)syndromes and the serum concentration of zinc,iron,copper and magnesium of patients with chronic hepatitis B(CHB) and hepatitis B virus(HBV)-induced liver cirrhosis.METHODS:A total of 86 patients were included in the study between March 1,2009 and January 1,2010.All were diagnosed with CHB or HBV-induced liver cirrhosis according to the diagnosis standard of the Chinese Medical Association.Fasting serum concentrations of zinc,iron,copper and magnesium were measured.Patients were classified into different patterns of TCM symptoms according to TCM theory and clinical experience.RESULTS:In the HBV-induced liver cirrhosis group,the mean zinc concentration in patients with the TCM pattern of stagnation of fluid-Dampness was lower than that in patients with obstruction of collaterals by Blood stasis(P < 0.034).In the CHB group,the mean magnesium concentration in patients with toxic Heat flourishing was significantly lower than that in those with Damp-Heat in the Liver and Gallbladder,and those with Liver depression and Spleen deficiency(P < 0.021).The concentrations of iron and copper showed little difference among the different TCM symptom patterns.CONCLUSION:The serum zinc and magnesium concentrations correlated with certain TCM patterns of symptoms in patients with HBV-induced liver cirrhosis and CHB.It may be helpful to interpret the pathogenic change in the TCM symptom patterns in liver cirrhosis and CHB,and also to conduct clinical treatment of the diseases based on identified TCM patterns. | Teng Lichun Zhang Jiongshan Dai Min Wang Fenglin Yang Hongzhi | 2015 | Journal of Traditional Chinese Medicine2015,35,5: | 6 |
| 13 | Serum Gamma-glutamyl Transferase Levels Predict Functional Outcomes after Aneurysmal Subarachnoid Hemorrhage显示文摘Objective We aim to explore the potential association between serum gamma-glutamyl transferase levels and functional outcome after aneurysmal subarachnoid hemorrhage in a Chinese population. Methods A total of 386 aneurysmal subarachnoid hemorrhage patients were included in the study from September 2007 to February 2015. Baseline serum gamma-glutamyl transferase levels and 6-month follow-up functional outcomes were determined. A poor outcome was defined as a modified ranking scale score of ≥ 3. The multivariable logistic model was used to analyze the relationship between serum gamma-glutamyl transferase and clinical outcomes after aneurysmal subarachnoid hemorrhage. Results The adjusted poor outcome rates of patients with gamma-glutamyl transferase levels of < 30 U/L, 30-50 U/L and ≥ 50 U/L were 16.7%, 19.6%, and 34.4%, respectively(P < 0.01). The age-sex and multivariable adjusted odds ratios(95% confidence intervals) of poor prognosis comparing the top group(≥ 50 U/L) with the lowest group(< 30 U/L) were 5.76(2.74-12.13), 6.64(2.05-21.52), and 6.36(1.92-21.02). A significant linear trend existed between gamma-glutamyl transferase level and aneurysmal subarachnoid hemorrhage prognosis. This association was also observed among nondrinkers. Conclusion Patients with higher gamma-glutamyl transferase levels were more likely to have a poor prognosis. Serum gamma-glutamyl transferase can be considered to be an independent predictor of functional outcomes after aneurysmal subarachnoid hemorrhage. | XU Tian WANG Wei ZHAI Lin ZHANG Yun Feng ZHOU Hong Zhi WU Xin Min LI Ai Hong XIE Li Li NING Xiao Jin JI Yu Teng WANG Hong Mei KE Kai Fu | 2017 | Biomedical and Environmental Sciences2017,30,3: | 5 |

| 15 | Analysis of the effects of the heat of sorption on the process of heat transfer in moisture exchange across a membrane显示文摘A theoretical study has been conducted to investigate the effects of mass transfer on heat transfer in moisture exchange across a membrane and a mathematical model describing the heat transfer process with consideration of the heat of sorption was established.A dimensionless variable,Ψ =JLλ /δ(T10-T20),which controls the effect of the heat of sorption on the heat transfer in membrane process,was obtained through theoretical analysis,and the effects of Ψ on the heat transfer process were analyzed.Results showed that in the case that the temperature gradient and mass transfer are in the same direction,the effective heat flux changes the direction at Ψ =1.For Ψ <1,the heat transfers from high to low temperature sides through the membrane,and the total thermal resistance increases with increasing the moisture flux across membrane or reducing the temperature difference between the bulk flows on the two sides of membrane.For Ψ >1,the overall effect of the heat and mass transfer is that the effective heat flux points from low to high temperature sides and the total thermal resistance decreases with increasing the mass flux or reducing the temperature difference.In the case that the tem-perature gradient and mass transfer are in the opposite directions,the existence of the heat of sorption acts to enhance the heat transfer from high to low temperature sides,causing a reduced total thermal resistance,and the greater the mass flux or the smaller the temperature difference,the smaller the total thermal resistance. | Teng Hu JingChun Min YaoZu Song | 2008 | Science China(Technological Sciences)2008,51,12: | 5 |
| 16 | Analysis of grinding mechanics and improved grinding force model based on randomized grain geometric characteristics显示文摘Too high grinding force will lead to a large increase in specific grinding energy, resulting in high temperature in grinding zone, especially for the aerospace difficult cutting metal materials,seriously affecting the surface quality and accuracy. At present, the theoretical models of grinding force are mostly based on the assumption of uniform or simplified morphological characteristics of grains, which is inconsistent with the actual grains. Especially for non-engineering grinding wheel,most geometric characteristics of grains are ignored, resulting in the calculation accuracy that cannot guide practical production. Based on this, an improved grinding force model based on random grain geometric characteristics is proposed in this paper. Firstly, the surface topography model of CBN grinding wheel is established, and the effective grain determination mechanism in grinding zone is revealed. Based on the known grinding force model and mechanical behavior of interaction between grains and workpiece in different stages, the concept of grain effective action area is proposed. The variation mechanism of effective action area under the influence of grain geometric and spatial characteristics is deeply analyzed, and the calculation method under random combination of five influencing parameters is obtained. The numerical simulation is carried out to reveal the dynamic variation process of grinding force in grinding zone. In order to verify the theoretical model, the experiments of dry grinding Ti-6Al-4 V are designed. The experimental results show that under different machining parameters, the results of numerical calculation and experimental measurement are in good agreement, and the minimum error value is only 2.1 %, which indicates that the calculation accuracy of grinding force model meets the requirements and is feasible. This study will provide a theoretical basis for optimizing the wheel structure, effectively controlling the grinding force range, adjusting the grinding zone temperature and improving the workpiece machining quality in the industrial grinding process. | Mingzheng LIU Changhe LI Yanbin ZHANG Min YANG Teng GAO Xin CUI Xiaoming WANG Wenhao XU Zongming ZHOU Bo LIU Zafar SAID Runze LI Shubham SHARMA | 2023 | Chinese Journal of Aeronautics2023,36,7: | 5 |
| 17 | Refinement of primary Si in Cu-50Si alloys with novel Al-Zr-P master alloy显示文摘In this article, a novel Al-6Zr-2P master alloy with ZrP particles was successfully synthesized, and the refining performance of this novel master alloy for the primary Si in Cu-50Si alloys was also investigated. By means of the fracture plane observation, it is found that the ZrP phase would precipitate first in the solidification process, and then, the ZrAl 3 phase grows around them. Furthermore, it is observed that the refining effect can be remarkably improved by changing the addition sequence of the raw materials. After the melting of commercial Cu, the 2.0 wt% Al-6Zr-2P master alloy and crystalline Si were added in sequence, and the mean size of the primary Si in Cu-50Si alloy can be significantly refined from 255.7 to 75.3 lm.

| 18 | Gaseous sulfur trioxide induced controllable sulfonation promoting biomineralization and osseointegration of polyetheretherketone implants显示文摘Fabricating a desired porous structure on the surface of biomedical polyetheretherketone(PEEK)implants for enhancing biological functions is crucial and difficult due to its inherent chemical inertness.In this study,a porous surface of PEEK implants was fabricated by controllable sulfonation using gaseous sulfur trioxide(SO3)for different time(5,15,30,60 and 90 min).Micro-topological structure was generated on the surface of sulfonated PEEK implants preserving original mechanical properties.The protein absorption capacity and apatite forming ability was thus improved by the morphological and elemental change with higher degree of sulfonation.In combination of the appropriate micromorphology and bioactive sulfonate components,the cell adhesion,migration,proliferation and extracellular matrix secretion were obviously enhanced by the SPEEK-15 samples which were sulfonated for 15 min.Finding from this study revealed that controllable sulfonation by gaseous SO3 would be an extraordinarily strategy for improving osseointegration of PEEK implants by adjusting the microstructure and chemical composition while maintaining excellent mechanical properties. | Teng Wan Zixue Jiao Min Guo Zongliang Wang Yizao Wan Kaili Lin Qinyi Liu Peibiao Zhang | 2020 | Bioactive Materials2020,5,4: | 5 |
| 19 | Electrostatic atomization minimum quantity lubrication machining:from mechanism to application显示文摘Metal cutting fluids(MCFs)under flood conditions do not meet the urgent needs of reducing carbon emission.Biolubricant-based minimum quantity lubrication(MQL)is an effective alternative to flood lubrication.However,pneumatic atomization MQL has poor atomization properties,which is detrimental to occupational health.Therefore,electrostatic atomization MQL requires preliminary exploratory studies.However,systematic reviews are lacking in terms of capturing the current research status and development direction of this technology.This study aims to provide a comprehensive review and critical assessment of the existing understanding of electrostatic atomization MQL.This research can be used by scientists to gain insights into the action mechanism,theoretical basis,machining performance,and development direction of this technology.First,the critical equipment,eco-friendly atomization media(biolubricants),and empowering mechanisms of electrostatic atomization MQL are presented.Second,the advanced lubrication and heat transfer mechanisms of biolubricants are revealed by quantitatively comparing MQL with MCF-based wet machining.Third,the distinctive wetting and infiltration mechanisms of electrostatic atomization MQL,combined with its unique empowering mechanism and atomization method,are compared with those of pneumatic atomization MQL.Previous experiments have shown that electrostatic atomization MQL can reduce tool wear by 42.4%in metal cutting and improve the machined surface Ra by 47%compared with pneumatic atomization MQL.Finally,future development directions,including the improvement of the coordination parameters and equipment integration aspects,are proposed. | Wenhao Xu Changhe Li Yanbin Zhang Hafiz Muhammad Ali Shubham Sharma Runze Li Min Yang Teng Gao Mingzheng Liu Xiaoming Wang Zafar Said Xin Liu Zongming Zhou | 2022 | International Journal of Extreme Manufacturing2022,4,4: | 4 |
| 20 | Phosphorus forms and distribution in Zhejiang coastal sediment in the East China Sea显示文摘Surface and core sediment samples were collected from Zhejiang coastal waters of the East China Sea to study phosphorus(P) forms and understand the potential release of P as well as adsorption.The sediments were extracted sequentially to determine four phosphorus fractions,and non-sequentially for total phosphorus(TP).The total concentration of phosphorus in the surface sediments ranged from 527.2 to 680.5 mg kg^(-1).Inorganic P was the major form and accounted for 84-94%of TP.Among the four forms,P-Detrital was dominant(58.6-73.2%),followed by P-CDB(10.5-20.9%),P-Organic(6.1-15.9%),and P-CFA(5.9-16.3%).The distribution pattern of TP in the surface sediments was similar to that of P-Detrital and P-Organic,but different from P-CDB and P-CFA.A relatively high level of phosphorus was observed in estuarine sediments,reflecting the influence from terrestrial input.Phosphorus in all forms in core sediments at each station decreased with depth.In addition,potentially bio-available phosphorus accounted for 20-34%of TP. | Min CONG Tao JIANG Yu-zao QI Hong-po DONG De-qiang TENG Song-hui LU | 2014 | International Journal of Sediment Research2014,29,2: | 4 |
