| 1 | Intercropping with Solanum nigrum and Solanum photeinocarpum from Two Ecoclimatic Regions Promotes Growth and Reduces Cadmium Uptake of Eggplant Seedlings显示文摘Soil contamination by heavy metals is a serious environmental problem worldwide, and reduction of heavy metal accumulation in vegetables grown on contaminated land is a matter of urgency. A pot experiment was conducted to study the effects of intercropping with the Cd hyperaccumulators Solanum nigrum and Solanum photeinocarpum from two ecoclimatic regions, Ya'an and Chengdu,Sichuan Province, China, on the growth and cadmium(Cd) uptake of eggplant(Solanum melongena L.). The biomass, photosynthetic pigment contents, and activities of antioxidant enzymes of eggplant were enhanced by intercropping. The biomass of eggplant was the highest after intercropping with S. photeinocarpum from Ya'an, but did not differ significantly from that after intercropping with S. nigrum from Chengdu. The shoot Cd content of eggplant was significantly reduced by intercropping with the hyperaccumulators,which ranked as follows: S. nigrum from Chengdu > S. nigrum from Ya'an > S. photeinocarpum from Chengdu > S. photeinocarpum from Ya'an, with the decreases being 19.60%, 14.36%, 9.66%, and 6.42%, respectively, as compared with the control. The lowest shoot Cd content and translocation factor of eggplant were attained after intercropping with S. nigrum from Chengdu. Therefore, it was feasible to intercrop eggplant with S. nigrum and S. photeinocarpum on Cd-contaminated soil. | TANG Yi HE Juan YU Xuena XIE Yongdong LIN Lijin SUN Guochao LI Huanxiu LIAO Mingan LIANG Dong XIA Hui WANG Xun ZHANG Jing LIU Zejing TU Lihua LIU Li | 2017 | Pedosphere2017，27，3： | 17 |
| 2 | 4D printing of personalized shape memory polymer vascular stents with negative Poisson’s ratio structure:A preliminary study显示文摘Four-dimensional(4D)printing,integrates transformation information into three-dimensional(3D)-printed structures,which means that 3D-printed structures are able to change their shapes,properties,or functionalities over time.Here,two types of shape memory personalized vascular stents with negative Poisson’s ratio structure are developed via 4D printing.The genetic algorithm is used to optimize the structure.Axial compression tests,radial compression tests and three-point bending tests are carried out to study the mechanical properties of the stents.In addition,fluid-structure interaction and stress distribution during the shape recovery process are investigated based on finite element method.The shape memory behaviors of the stents are excellent and in vitro feasibility tests demonstrate that the stents can expand the simulated narrow blood vessel rapidly.Therefore,4D printed shape memory stents with negative Poisson’s ratio structure are highly promising for the treatment of vascular stenosis. | LIN Cheng ZHANG LiJin LIU YanJu LIU LiWu LENG JinSong | 2020 | Science China(Technological Sciences)2020，63，4： | 3 |
| 3 | Association Between Lipid Profiles and Left Ventricular Hypertrophy:New Evidence from a Retrospective Study显示文摘Objective To explore the association between lipid profiles and left ventricular hypertrophy in a Chinese general population.Methods We conducted a retrospective observational study to investigate the relationship between lipid markers[including triglycerides,total cholesterol,low-density lipoprotein cholesterol,high-density lipoprotein(HDL)cholesterol,non-HDL-cholesterol,apolipoprotein A-I,apolipoprotein B,lipoprotein[a],and composite lipid profiles]and left ventricular hypertrophy.A total of 309,400 participants of two populations(one from Beijing and another from nationwide)who underwent physical examinations at different health management centers between 2009 and 2018 in China were included in the cross-sectional study.7,475 participants who had multiple physical examinations and initially did not have left ventricular hypertrophy constituted a longitudinal cohort to analyze the association between lipid markers and the new-onset of left ventricular hypertrophy.Left ventricular hypertrophy was measured by echocardiography and defined as an end-diastolic thickness of the mterventricular septum or left ventricle posterior wall>11 mm.The Logistic regression model was used in the cross-sectional study.Cox model and Cox model with restricted cubic splines were used in the longitudinal cohort.Results In the cross-sectional study for participants in the highest tertile of each lipid marker compared to the respective lowest,triglycerides[odds ratio(OR):1.2S0,95%CI:1.060 to 1.474],HDL-cholesterol(OR:0.780,95%CI:0.662 to 0.918),and lipoprotein(a)(OR:1.311,95%C7:1.115 to 1.541)had an association with left ventricular hypertrophy.In the longitudinal cohort,for participants in the highest tertile of each lipid marker at the baseline compared to the respective lowest,triglycerides[hazard ratio(HR):3.277,95%C/:1.720 to 6.244],HDL-cholesterol(HR:0.516,95%C7:0.283 to 0.940),non-HDL-cholesterol(HR:2.309,95%C/:1.296 to 4.112),apolipoprotein B(HR:2.244,95%CI:1.251 to 4.032)showed an association with new-onset left ventricular hypertrophy.In the Cox model with forward stepwise selection,triglycerides were the only lipid markers entered into the final model.Conclusion Lipids levels,especially triglycerides,are associated with left ventricular hypertrophy.Controlling triglycerides level potentiate to be a strategy in harnessing cardiac remodeling but deserve to be furdier investigated. | Xuewei Huang Keqiong Deng Juanjuan Qin Fang Lei Xingyuan Zhang Wenxin Wang Lijin Lin Yuming Zheng Dongai Yao Huiming Lu Feng Liu Lidong Chen Guilan Zhang Yueping Liu Qiongyu Yang Jingjing Cai Zhigang She Hongliang Li | 2022 | Chinese Medical Sciences Journal2022，37，2： | 1 |

| 5 | Composite Design of Low Thermal Conductivity Mullite Brick for Application to Cement Kiln显示文摘In order to restrain cement kiln shell' s thermal loss and potential safety hazards,composite design was employed of working layer,thermal preservation layer and thermal insulation layer.Thermal preservation layer' s boundary and strain were analyzed and the overall thermal conductivity was calculated.The result shows that the sinusoidal curve boundary combination is adopted between the working layer and thermal preservation layer,and the slope-shape with angle of 135 degrees between the thermal preservation layer and thermal insulation layer could relieve the strain concentration.Comprehensive thermal conductivity of the composite mullite brick decreases from the working layer 2.74 W·m^(-1)·K^(-1) to1.54 W·m^(-1)·K^(-1).When applying the composite bricks in cement kilns,the kiln shell temperature is from50 ℃ to 70 ℃ lower than using normal bricks. | YUAN Lin WANG Juntao TONG Lijin ZHAO Hongliang LI Quanyou CHEN Songlin | 2016 | China's Refractories2016，25，4： | 0 |
| 6 | Modified Circumpolar Deep Water inflow to the Dotson-Getz Trough in the summers of 2020 and 2022显示文摘The melting of the West Antarctic Ice Shelf has increased since the 1990s,driven by the relatively warm Circumpolar Deep Water(CDW)that penetrates into the West Antarctic Ice Shelf cavities through submarine glacial troughs across the continental shelf.In this study,temperature,salinity,and current velocity data obtained by the Chinese National Antarctic Research Expedition in the Dotson-Getz Trough(DGT)shows clear differences in distribution of modified Circumpolar Deep Water(mCDW)in the summers of 2020 and 2022.Combined with contemporaneous wind data and additional temperature and salinity data from instrumented seals,the processes and mechanisms responsible for this variation are discussed.Compared with 2020,there is a significant increase in mCDW thickness in 2022,with a doubling of total heat content as the mCDW inflow path across the DGT shifts towards the eastern bank.We propose that a southward shift in the westerly winds in the summer of 2022 moved the upper oceanic divergence zone southward towards the continental slope,promoting the upwelling of mCDW above 500 m.Concurrently,stronger westerly winds over the continental slope strengthened the eastward undercurrent,increasing the transport of this mCDW and its associated heat content to the DGT through Ekman dynamics.These observations show there is strong interannual variability in the strength,path and extent of mCDW inflows to the DGT and that care must be taken when planning observation programs for long-term monitoring of the oceanic heat input to the ice shelves of this globally significant region. | XIE Chunhu SHI Jiuxin SUN Yongming JIANG Jindong Guy DWILLIAMS SHUAI Hongtao LIN Lijin XIAO Changhao CAO Yong WANG Kun | 2023 | Advances in Polar Science2023，34，2： | 0 |
| 7 | Carotenoid components and their biosynthesis in a bud mutant of Shiranui mandarin(Citrus reticulata Blanco)with citrine flavedo显示文摘Carotenoids are secondary metabolite responsible for colored pigments in plants and microbes(Li et al.,2022).They are a class of C40 tetraterpenoids consisting of eight isoprenoid units,and can be classified into carotenes and xanthophylls on the basis of their functional groups(Saini et al.,2015).Carotenes can be lin‐ear(phytoene,phytofluene,andζ-carotene)or branched(β-carotene andα-carotene).Xanthophylls compriseβ,β-xanthophylls(β-cryptoxanthin,zeaxanthin,violaxanthins,and neoxanthin)andβ,ε-xanthophylls(α-cryptoxanthin,α-carotene,and lutein). | Xun WANG Jinqiu HUANG Zongyan YIN Ke XU Dong JIANG Lijin LIN Xiaoai ZHANG Zhihui WANG | 2023 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023，24，1： | 0 |
