| 1 | Heavy metals in rice and garden vegetables and their potential health risks to inhabitants in the vicinity of an industrial zone in Jiangsu, China显示文摘Contamination of soil and agricultural products by heavy metals resulting from rapid industrial development has caused major concern. In this study, we investigated heavy metal (Cu, Zn, Pb, Cr, Hg and Cd) concentrations in rice and garden vegetables, as well as in cultivated soils, in a rural-industrial developed region in southern Jiangsu, China, and estimated the potential health risks of metals to the inhabitants via consumption of locally produced rice and garden vegetables. A questionnaire-based survey on dietary consumption rates of foodstuffs showed that rice and vegetables accounted for 64% of total foodstuffs consumed, and over 60% of rice and vegetables were grown in the local region. Average concentrations of Cr, Cu, Zn, Cd, Hg and Pb were 0.75, 2.64, 12.00, 0.014, 0.006 and 0.054 mg/kg dw (dry weight) in rice and were 0.67, 1.18, 4.34, 0.011, 0.002 and 0.058 mg/kg fw (fresh weight) in garden vegetables, respectively. These values were all below the maximum allowable concentration in food in China except for Cr in vegetables. Leafy vegetables had higher metal concentrations than solanaceae vegetables. Average daily intake of Cr, Cu, Zn, Cd, Hg and Pb through the consumption of rice and garden vegetables were 5.66, 16.90, 74.21, 0.10, 0.04 and 0.43 μg/(kg·day), respectively. Although Hazard Quotient values of individual metals were all lower than 1, when all six metal intakes via self-planted rice and garden vegetables were combined, the Hazard Index value was close to 1. Potential health risks from exposure to heavy metals in self-planted rice and garden vegetables need more attention. | Hongbin Cao Jianjiang Chen Jun Zhang Hui Zhang Li Qiao Yi Men | 2010 | Journal of Environmental Sciences2010，22，11： | 61 |

| 3 | Tiny YOLO Optimization Oriented Bus Passenger Object Detection显示文摘The real-time collection of bus passenger object detection is an essential part of developing a smart bus system.The difficulty of object detection mainly lies in the objective factors,such as:clothing,hair style and accessories,light,etc.Traditional object detection met hods with the arti ficial feature ext rac tion suffers from insufficien t st reng th in expression,generalization,and recogni tion rate.The objec t detection met hod based on deep learning mainly uses the convol utio nal neural net work in deep learning to learn features from a large set of data.The learned features can describe the rich infbrmation inherent in the data,and improve the expression ability of the features as well as the recognition accuracy.Due to too many parameters of the Convolutional neural network(CNN)model,the amount of calculation is too large to be opera ted on the vehicle terminal.To reduce calculation burden and improve the operation speed,we employs the depthwise separable convolution method to optimize the convolutional layer of tiny YOLO net work model.It decomposes a complete convolution operation into depthwise convolution and pointwise convolution,thus reducing the parameter amount of the CNN and improving the operation speed.The experiment results reveal that the speed of bus passenger object detection detected by our improved model is 4 times faster than the previous one but with the nearly same detection accuracy. | ZHANG Shuo WU Yanxia MEN Chaoguang LI Xiaosong | 2020 | Chinese Journal of Electronics2020，29，1： | 15 |
| 4 | Preparation and coking properties of coal maceral concentrates显示文摘The concentrates with different maceral contents were obtained from Kailuan coking coals with different coal ranks(Ro;ranvarying from 0.88%to 1.73%)by float–sink separation in lab.Then these concentrates were characterized by proximate analysis,ultimate analysis,petrography analysis and coking index determination.The results show that the vitrinite is characterized as nature of lower carbon content,higher hydrogen content,higher volatile matter and stronger caking property compared to inertinite.The relationships between variation rate of volatile matter and maximum volatile matter and coal ranks are identified,and a linear model is developed for fast determination of the maceral contents.Compared to inertinite-rich concentrate,the blending ratio of vitrinite-rich concentrate is increased by 13%,which is considered to be a potential technique based on maceral separation for expanding the coking coal resources. | Zhang Lei Liu Wenli Men Dongpo | 2014 | International Journal of Mining Science and Technology2014，24，1： | 12 |

| 7 | Pollen Typhae Total Flavone Inhibits Endoplasmic Reticulum Stress-Induced Apoptosis in Human Aortic-Vascular Smooth Muscle Cells through Down-Regulating PERK-eIF2α-ATF4-CHOP Pathway显示文摘Objective: To test the hypothesis that the inhibition of endoplasmic reticulum(ER) stress-induced apoptosis in oxidized low-density lipoproteins(ox-LDL)-induced human aortic-vascular smooth muscle cells(HA-VSMCs) was associated with suppression of the protein kinase RNA-like ER kinase(PERK)-eukaryotic translation initiation factor 2α(e IF2α)-activating transcription factor 4(ATF4)-CCAAT/enhancer binding protein homologous protein(CHOP) signaling pathway by Pollen Typhae total flavone(PTF). Methods: Primary HA-VSMCs were cultured and identified. The cultured HA-VSMCs were randomized into 5 groups, including a normal control group, an ox-LDL group(70 μg/m L high ox-LDL), an HPTF group(70 μg/m L high ox-LDL+500 μg/m L PTF), an MPTF group(70 μg/m L high ox-LDL+250 μg/m L PTF), and a LPTF group(70 μg/m L high ox-LDL+100 μg/m L PTF) in the first part;and a normal control group, an ox-LDL group(70 μg/mL high ox-LDL), an MPTF group(70 μg/m L high ox-LDL+250 μg/m L PTF), a sh RNA group(transducted with PERK shRNA lentiviral particles), a scramble shRNA group(transducted with control shRNA lentiviral particles), an MPTF+ox-LDL+shRNA group(250 μg/mL PTF+70 μg/mL high ox-LDL+PERK shRNA lentiviral particles) and an ox-LDL+shRNA group(70 μg/mL high ox-LDL+PERK shRNA lentiviral particles) in the second part. The protein expression levels of ER-associated apoptosis proteins were detected by Western blot, and their m RNA expression levels were detected by quantitative real-time reverse transcription-polymerase chain reaction. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay was applied to test cel viability, and the level of apoptosis was monitored by flow cytometry. Results: The MTT assay and flow cytometry showed that the ox-LDL group had a significant increase in apoptosis, which was attenuated in PTF treatment groups and sh RNA groups. Moreover, the ox-LDL group had increased protein and m RNA levels of binding immunoglobulin protein and ER-associated apoptosis proteins, such as PERK, e IF2α, ATF4 and CHOP, which were attenuated in PTF treatment groups and sh RNA groups. Conclusions: The apoptosis induced by ox-LDL had a strong relation to ER stress. The protective effect of PTF on ER stressinduced apoptosis was associated with inhibition of the PERK-eIF2α-ATF4-CHOP pathway, which might be a potential therapeutic strategy for enhancing the stability of atherosclerotic plaques. | CHEN Ming-tai HUANG Ruo-lan OU Li-jun CHEN Ying-nan MEN Ling CHANG Xiao WANG Ling YANG Yu-zhu ZHANG Zhong | 2019 | Chinese Journal of Integrative Medicine2019，25，8： | 9 |
| 8 | Tolerance to low phosphorus in rice varieties is conferred by regulation of root growth显示文摘Phosphorus use efficiency(PUE)can be improved through cultivation techniques and breeding.However,little is known about rice(Oryza sativa L.)agronomic and physiological traits associated with high PUE.We characterized the agronomic and physiological traits of rice varieties with different tolerances to low phosphorus in nutrient solution.Two varieties with strong tolerance to low phosphorus(STVs)and two with weak tolerance(WTVs)were grown at normal(NP,control)and low phosphorus(LP,1/20 of NP)concentrations.Plants grown at LP produced significantly lower grain yield than those grown at NP.WTVs yields were lower than STVs yields.Compared to NP,LP significantly increased phosphorus translocation efficiency(PTE),internal phosphorus efficiency(IPE)and phosphorus harvest index(PHI).Under the LP condition,PTE and IPE were higher for STVs than for WTVs.LP also reduced tiller number,shoot biomass,leaf area index(LAI),leaf photosynthetic rate,and mean root diameter of both kinds of varieties at the main growth stages,but to a lower extent in STVs.LP significantly increased the number of productive tillers,root biomass,root-shoot ratio,root bleeding rate,and root acid phosphatase(RAP)activity.Total root length,root oxidation activity(ROA),and root total and active absorbing surface areas for STVs were significantly increased under LP,whereas the opposite responses were observed for WTVs.Total root length,ROA,root bleeding rate,root active absorbing surface area,and RAP activity were positively and significantly correlated with grain yield,PTE,and IPE.These results suggest that the tolerance of rice varieties to a low-phosphorus growth condition is closely associated with root growth with higher biomass and activity. | Yaping Deng Chuanbao Men Shengfeng Qiao Wenjie Wang Junfei Gu Lijun Liu Zujian Zhang Hao Zhang Zhiqin Wang Jianchang Yang | 2020 | The Crop Journal2020，8，4： | 8 |
| 9 | Microsatellite polymorphisms of Sichuan golden monkeys显示文摘Previous study using protein electrophoresis shows no polymorphism in 44 nuclear loci of Sichuan golden monkey (Rhinopithecus roxellana), which limits our understandings of its population genetic patterns in the nuclear genome. In order to obtain sufficient information, we scanned 14 microsatellite loci in a sample of 32 individuals from its three major habitats (Minshan, Qinling and Shen-nongjia). A considerable amount of polymorphisms were detected. The average heterozygosities in the local populations were all above 0.5. The differentiations among local populations were significant. There was evidence of geneflow among subpopulations, but geneflow between Qinling and Shennongjia local populations was the weakest. Minshan and Qinling populations might have gone through recent bottlenecks. The estimation of the ratio of the effective population sizes among local populations was close to that from census sizes. Comparisons to available mitochondria data suggested that R. roxellana’s social structures played an important role in shaping its population genetic patterns. Our study showed that the polymorphism level of R. roxellana was no higher than other endangered species; therefore, measures should be taken to preserve genetic diversity of this species. | PAN Deng LI Ying HU Hongxing MENG Shijie MEN Zhengming FU Yunxin ZHANG Yaping | 2005 | Chinese Science Bulletin2005，50，24： | 7 |
| 10 | Friction and wear behaviors of MoS2-multi-walled-carbonnanotube hybrid reinforced polyurethane composite coating显示文摘MoS2-multi-walled-carbon-nanotube(MWCNT)hybrids containing two-dimensional MoS2 and one-dimensional MWCNTs were synthesized through a one-step hydrothermal reaction.X-ray-diffraction and transmission-electron-microscopy results demonstrated that MoS2 nanosheets were successfully synthesized,and uniformly anchored on the MWCNTs’surfaces.Furthermore,the effects of the Mo S2-MWCNT hybrids on the tribological performances of polyurethane composite coatings were investigated using a UMT-2MT tribo-tester.Friction and wear test results revealed that the friction coefficient and wear rate of a 3 wt%Mo S2-MWCNT-1 filled polyurethane composite coating were reduced by 25.6% and 65.5%,respectively.The outstanding tribological performance of the MoS2-MWCNT-1 reinforced polyurethane composite coating was attributed to the excellent load-carrying capacity of the MWCNTs and good lubricant ability of MoS2.The surface morphologies of the worn surfaces and counterpart ball surfaces were investigated to reveal the wear mechanisms. | Zhaozhu ZHANG Mingming YANG Junya YUAN Fang GUO Xuehu MEN | 2019 | Friction2019，7，4： | 7 |
| 11 | Effect of Ni addition on the glass-forming ability and soft-magnetic properties of FeNiBPNb metallic glasses显示文摘The effect of Ni addition on the glass-forming ability (GFA) and soft-magnetic properties of an (Fe1-xNix)75.5B14.5P7Nb3 (x=0-0.6) alloy system were investigated. We found that the addition of Ni was effective in allowing the alloy to approach a eutectic point as well as increasing the thermal stability of the supercooled liquid. By increasing the amount of Ni,the supercooled liquid region (ΔTx),the reduced glass transition temperature Trg (Tg/Tl) and the Y parameter [Tx/(Tg+Tl)] increased from 49 to 75 K,0.540 to 0.594 and 0.373 to 0.405,respectively. As a result,novel (Fe1-xNix)75.5B14.5P7Nb3 bulk metallic glass (BMG) rods with a maximum diameter of 1 mm were synthesized with a composition of x=0.5 and x=0.6 by copper mold casting. These metallic glasses have a moderate saturation magnetization of 0.37-1.20 T with good soft-magnetic properties,i.e. a low coercivity of 1.4-3.3 A/m and a high effective permeability of 13100-20900 at 1 kHz. The simultaneous achievement of a high GFA and good soft-magnetic properties for the FeNi-based alloy system is promising for the future development of BMGs. | WANG AnDing ZHANG MingXiao ZHANG JianHua MEN He SHEN BaoLong PANG ShuJie ZHANG Tao | 2011 | Chinese Science Bulletin2011，56，36： | 7 |
| 12 | Channel Measurement and Path Loss Modeling from 220 GHz to 330 GHz for 6G Wireless Communications显示文摘Terahertz(THz)communication has been envisioned as a key enabling technology for sixthgeneration(6G).In this paper,we present an extensive THz channel measurement campaign for 6G wireless communications from 220 GHz to 330 GHz.Furthermore,the path loss is analyzed and modeled by using two single-frequency path loss models and a multiplefrequencies path loss model.It is found that at most frequency points,the measured path loss is larger than that in the free space.But at around 310 GHz,the propagation attenuation is relatively weaker compared to that in the free space.Also,the frequency dependence of path loss is observed and the frequency exponent of the multiple-frequencies path loss model is 2.1.Moreover,the cellular performance of THz communication systems is investigated by using the obtained path loss model.Simulation results indicate that the current inter-site distance(ISD)for the indoor scenario is too small for THz communications.Furthermore,the tremendous capacity gain can be obtained by using THz bands compared to using microwave bands and millimeter wave bands.Generally,this work can give an insight into the design and optimization of THz communication systems for 6G. | Pan Tang Jianhua Zhang Haoyu Tian Zhaowei Chang Jun Men Yuxiang Zhang Lei Tian Liang Xia Qixing Wang Jingsuo He | 2021 | China Communications2021，18，5： | 7 |

| 14 | In situ reduction and functionalization of graphene oxide to improve the tribological behavior of a phenol formaldehyde composite coating显示文摘The development of a phenol formaldehyde/graphene(PF-graphene)composite coating with high performance is desirable but remains a challenge,because of the ultrahigh surface area and surface inertia of the graphene.Herein,we synthesized PF-graphene composites by the in situ polymerization of phenol and formaldehyde with the addition of graphene oxide,resulting in improved compatibility between the graphene and phenolic resin(PF)matrix and endowing the phenolic resin with good thermal stability and excellent tribological properties.Fourier-transform infrared(FTIR)spectra and X-ray diffraction(XRD)patterns demonstrated that the graphene oxide was reduced during the in-situ polymerization.The PF-graphene composites were sprayed onto steel blocks to form composite coatings.The effects of an applied load and of the sliding speed on the tribological properties of the PF-graphene composite coating were evaluated using a block-on-ring wear tester;in addition,the worn surface and the transfer film formed on the surface of the counterpart ring were studied by scanning electron microscopy(SEM).The results show that the PF-graphene composite coating exhibited enhanced tribological properties under all tested conditions. | Mingming YANG Zhaozhu ZHANG Xiaotao ZHU Xuehu MEN Guina REN | 2015 | Friction2015，3，1： | 6 |
| 15 | Combination of laparoscopic and open procedure in dismembered pyeloplasty: report of 51 cases显示文摘Background Laparoscopic dismembered pyeloplasty with less trauma than open surgery is commonly performed for ureteropelvic junction obstruction despite a longer operating time and a long learning curve. We describe in this paper a new technique, which combines laparoscopic and open procedure in dismembered pyeloplasty, that we have developed in 51 patients and achieved excellent results. Methods The surgical procedure can be divided into two steps: laparoscopic dissection of the renal pelvis and proximal ureter transperitoneally; then accomplishing the pyeloplasty through the extended port incision above the ureteropelvic junction as in open surgery. Results All 51 operations were successful without conversion to open surgery. No intraoperative complications were observed. The operating time was 40 minutes to 90 minutes with an average of 57.5 minutes. The estimated blood loss was 15 ml to 30 ml with an average of 21.2 ml. Aberrant artery vessel and primary stricture as the cause of ureteropelvic junction obstruction was noted in 2 and 49 patients, respectively. Thirty-nine patients had fever to differing extents in the 4 days postoperation and no severe infection was observed. Four patients had urinary leakage with their drains being retained for 6 days, 6 days, 5 days or 8 days after the operation. The mean followup was 10.8 months (range 3 months to 36 months). The followup showed good results with symptom resolution in all the patients. Renal ultrasonography demonstrated that the average separation of the collecting systems decreased from preoperative 2.7 cm (range 2.0 cm to 4.7 cm) to postoperative 1.5 cm (range 1.0 cm to 2.3 cm). Excretory urography at 3 months postoperatively showed improved drainage. Of the 51 patients, 35 underwent two or more excretory urograms, demonstrating stable renal function, improved drainage and no evidence of recurrent obstruction. At the last followup visit, each patient was doing well. Conclusions Combination of laparoscopic and open procedure in dismembered pyeloplasty offers a simpler, timesaving method in a minimally invasive fashion with low morbidity for patients with ureteropelvic junction obstruction. Ensuring quality of repair, the method provides a minimally invasive alternative with good results. It is worth future clinical application. | GAO Zhen-li SHI Lei YANG Ming-shan WANG Lin YANG Dian-dong SUN De-kang LIU Qing-zuo MEN Chang-ping WU Ji-tao ZHANG Peng | 2006 | Chinese Medical Journal2006，，10： | 6 |

| 17 | Establishment of a mouse model of cancer cachexia with spleen deficiency syndrome and the effects of atractylenolide I显示文摘Cancer cachexia is a multifactorial metabolic syndrome that affects~50%–80%of cancer patients,and no effective therapy for cancer cachexia is presently available.In traditional Chinese medicine,a large portion of patients with cancer cachexia was diagnosed as spleen deficiency syndrome and treated with tonifying TCMs that produce clinic benefits.In this study we established a new animal model of spleen deficiency and cancer cachexia in mice and evaluated the therapeutic effects of atractylenolide I,an active component of tonifying TCM BaiZhu,in the mouse model.Cancer cachexia was induced in male BALB/c mice by inoculation of mouse C26 colon adenocarcinoma cells,whereas spleen deficiency syndrome was induced by treating the mice with spleen deficiency-inducing factors,including limited feeding,fatigue,and purging.The mouse model was characterized by both cachexia and spleen deficiency characteristics,including significant body weight loss,cancer growth,muscle atrophy,fat lipolysis,spleen,and thymus atrophy as compared with healthy control mice,cancer cachexia mice,and spleen deficiency mice.Oral administration of atractylenolide I(20 mg·kg?1per day,for 30 days)significantly ameliorated the reduction in body weight and atrophy of muscle,fat,spleen,and thymus in mice with spleen deficiency and cachexia.The established model of spleen deficiency and cancer cachexia might be useful in the future for screening possible anticachexia TCMs and clarifying their mechanisms. | Wan-li Zhang Na Li Qiang Shen Men Fan Xiao-dong Guo Xiong-wen Zhang Zhou Zhang Xuan Liu | 2020 | Acta Pharmacologica Sinica2020，41，2： | 6 |

| 20 | The FAST Galactic Plane Pulsar Snapshot survey:I.Project design and pulsar discoveries显示文摘Discovery of pulsars is one of the main goals for large radio telescopes.The Five-hundredmeter Aperture Spherical radio Telescope(FAST),that incorporates an L-band 19-beam receiver with a system temperature of about 20 K,is the most sensitive radio telescope utilized for discovering pulsars.We designed the snapshot observation mode for a FAST key science project,the Galactic Plane Pulsar Snapshot(GPPS)survey,in which every four nearby pointings can observe a cover of a sky patch of 0.1575 square degrees through beam-switching of the L-band 19-beam receiver.The integration time for each pointing is 300 seconds so that the GPPS observations for a cover can be made in 21 minutes.The goal of the GPPS survey is to discover pulsars within the Galactic latitude of±10∘from the Galactic plane,and the highest priority is given to the inner Galaxy within±5∘.Up to now,the GPPS survey has discovered 201 pulsars,including currently the faintest pulsars which cannot be detected by other telescopes,pulsars with extremely high dispersion measures(DMs)which challenge the currently widely used models for the Galactic electron density distribution,pulsars coincident with supernova remnants,40 millisecond pulsars,16 binary pulsars,some nulling and mode-changing pulsars and rotating radio transients(RRATs).The follow-up observations for confirmation of new pulsars have polarization-signals recorded for polarization profiles of the pulsars.Re-detection of previously known pulsars in the survey data also leads to significant improvements in parameters for 64 pulsars.The GPPS survey discoveries are published and will be updated at http://zmtt.bao.ac.cn/GPPS/. | J.L.Han Chen Wang P.F.Wang Tao Wang D.J.Zhou Jing-Hai Sun Yi Yan Wei-Qi Su Wei-Cong Jing Xue Chen X.Y.Gao Li-Gang Hou Jun Xu K.J.Lee Na Wang Peng Jiang Ren-Xin Xu Jun Yan Heng-Qian Gan Xin Guan Wen-Jun Huang Jin-Chen Jiang Hui Li Yun-Peng Men Chun Sun Bo-Jun Wang H.G.Wang Shuang-Qiang Wang Jin-Tao Xie Heng Xu Rui Yao Xiao-Peng You D.J.Yu Jian-Ping Yuan Rai Yuen Chun-Feng Zhang Yan Zhu | 2021 | Research in Astronomy and Astrophysics2021，21，5： | 4 |
