| 1 | One-step disposal of Cr (Ⅵ)-bearing wastewater by natural pyrrhotite显示文摘Cr(Ⅵ)-bearing wastewater can be treated by natural pyrrhotite which is used for reductant to reduce Cr(Ⅵ) and precipitant to precipitate Cr(Ⅲ) simultaneously. The disposal products can be divided into three parts in the beakers, namely supernatant in the upper part, the yellowish colloidal precipitates in the middle part and the pyrrhotite in the lower part. The content of total Cr=Cr(Ⅵ)+Cr(Ⅲ) in the supernatant liquid is 0.06 mg/L, which is lower than 1.5 mg/L of the discharge standard of China and near to 0.05 mg/L of the standard of potable water. This one-step disposal composing of both reduction and precipitation which is traditionally divided into two independent steps called reducing technology and precipitating technology respectively. The new method is of obvious economic advantage and favourable to decreasing surplus mud derived from adding Ca(OH)2 to precipitate Cr(Ⅲ) traditionally so as to avoid recontamination. In fact, sodium sulfite (Na2SO3) used in disposal of Cr(Ⅵ) was | LU Anhuai, CHEN Jie, SHI Junxian, LU Xiaoying, TANG Junli & GUO Min1.

| 2 | Effects of Exposure to Lead and Cadmium on the Oxidative Damage of Livers in Laying Hens显示文摘[Objective] To detect the effects of exposure to lead and cadmium on the oxidative damage of livers in laying hens. [Methods] One hundred and twenty 40-week-old Hyline brown hens were randomly divided into four groups. 100 mg / L Pb and / or 50 mg / L Cd was added into the drinking water for eight weeks. [Results] Compared with control group,AST and ALT activities in Pb group enhanced; but there were no significant differences. AST and ALT activities in Cd group and( Pb + Cd) group significantly or extremely significantly increased( P < 0. 05 or P < 0. 01). SOD activity,GSH- Px activity and GSH content in( Pb + Cd) group,Cd group and Pb group were significantly or extremely significantly lower than those in control group( P <0. 05 or P <0. 01). Among them,( Pb + Cd) group showed the greatest reduction( P <0. 01). MDA contents in the three groups were significantly higher than that of control group; and( Pb +Cd) group was significantly higher than Pb group and Cd group. Cu,Fe and Zn contents in three groups were higher than those in control group in different degrees( P <0. 05 or P <0. 01). Se contents in Cd group and( Pb + Cd) group were significantly lower than that in control group( P <0. 01). Residue contents in livers in Pb group and Cd group were significantly greater than that in control group; while residue content in( Pb + Cd) group was significantly higher than those in Pb group and Cd group. Ultrastructure showed that there were symptoms of mitochondrial swelling and fractured cristae in liver cells of laying hens after the exposure to Cd and Pb. In( Pb + Cd) group,these symptoms were even greater. [Conclusion] Oxidative damage and disturbance of trace element metabolism were one of the mechanisms for hepatotocity in laying hens induced by Pb and Cd,and synergistic effect lied in the coadministration. | Chen Dawei Pu Junhua Tang Xiujun Lu Junxian Liu Yinyin Jia Xiaoxu Ge Qinglian Gao Yushi | 2014 | Animal Husbandry and Feed Science2014，6，5： | 1 |
| 3 | Thermal Runaway of Lithium-Ion Batteries Employing Flame-Retardant Fluorinated Electrolytes显示文摘Fluorinated electrolytes possess good antioxidant capacity that provides high compatibility to high-voltage cathode and flame retardance;thus,they are considered as a promising solution for advanced lithium-ion batteries carrying both high-energy density and high safety.Moreover,the fluorinated electrolytes are widely used to form stable electrolyte interphase,due to their chemical reactivity with lithiated graphite or lithium.However,the influence of this reactivity on the thermal safety of batteries is seldom discussed.Herein,we demonstrate that the flame-retardant fluorinated electrolytes help to reduce the flammability,while the lithium-ion batteries with flame-retardant fluorinated electrolytes still undergo thermal runaway and disclose their different thermal runaway pathway from that of battery with conventional electrolyte.The reduction in fluorinated components(e.g.,LiPF 6 and fluoroethylene carbonate(FEC))by fully lithiated graphite accounts for a significant heat release during battery thermal runaway.The 13%of total heat is sufficient to trigger the chain reactions during battery thermal runaway.This study deepens the understanding of the thermal runaway mechanism of lithium-ion batteries employing flame-retardant fluorinated electrolytes,providing guidance on the concept of electrolyte design for safer lithium-ion batteries. | Junxian Hou Li Wang Xuning Feng Junpei Terada Languang Lu Shigeaki Yamazaki Anyu Su Yoshiko Kuwajima Yongjiang Chen Tomoya Hidaka Xiangming He Hewu Wang Minggao Ouyang | 2023 | Energy & Environmental Materials2023，6，1： | 1 |
| 4 | Differences in functional magnetic resonance imaging following cutaneous and routine acupuncture at different acupoints显示文摘Few studies have examined the effects of different stimuli at a single acupoint using functional magnetic resonance imaging.The present study applied acupuncture at the Neiguan(PC 6),Waiguan(SJ 5),Zhigou(SJ 6) and Yanglingquan(GB 34) acupoints in healthy volunteers.fMRI was used to examine the activation of brain areas in response to different types of acupuncture(cutaneous or routine acupuncture) at each acupoint.There were no significant differences in the distribution of activation in the regions of interest between cutaneous and routine acupuncture at the Neiguan,Waiguan,and Zhigou acupoints,but some differences were observed between the two methods of acupuncture at the Yanglingquan acupoint.There were no significant differences in the intensity of induced activation between cutaneous and routine acupuncture at the Neiguan,Zhigou and Yanglingquan acupoints,but the activation intensity in the right cerebellum induced by routine acupuncture at the Waiguan acupoint was greater than that induced by cutaneous acupuncture.Results confirmed that cutaneous and routine acupuncture at the Neiguan,Waiguan,Zhigou and Yanglingquan acupoints activated different functional brain areas,and caused activation of different intensities in some areas. | Yangjia Lu Junxian Wu Yanqi Zou Junqi Chen Baoci Shan Jiarong Chen Yong Huang | 2011 | Neural Regeneration Research2011，6，15： | 1 |
| 5 | Scientific objectives of the Hot Universe Baryon Surveyor(HUBS) mission显示文摘The Hot Universe Baryon Surveyor(HUBS) is a proposed space-based X-ray telescope for detecting X-ray emissions from the hot gas content in our universe. With its unprecedented spatially-resolved high-resolution spectroscopy and large field of view,the HUBS mission will be uniquely qualified to measure the physical and chemical properties of the hot gas in the interstellar medium, the circumgalactic medium, the intergalactic medium, and the intracluster medium. These measurements will be valuable for two key scientific goals of HUBS, namely to unravel the AGN and stellar feedback physics that governs the formation and evolution of galaxies, and to probe the baryon budget and multi-phase states from galactic to cosmological scales. In addition to these two goals, the HUBS mission will also help us solve some problems in the fields of galaxy clusters, AGNs, difuse X-ray backgrounds, supernova remnants, and compact objects. This paper discusses the perspective of advancing these fields using the HUBS telescope. | Joel Bregman Renyue Cen Yang Chen Wei Cui Taotao Fang Fulai Guo Edmund Hodges-Kluck Rui Huang Luis C.Ho Li Ji Suoqing Ji Xi Kang Xiaoyu Lai Hui Li Jiangtao Li Miao Li Xiangdong Li Yuan Li Zhaosheng Li Guiyun Liang Helei Liu Wenhao Liu Fangjun Lu Junjie Mao Gabriele Ponti Zhijie Qu Chenxi Shan Lijing Shao Fangzheng Shi Xinwen Shu Lei Sun Mouyuan Sun Hao Tong Junfeng Wang Junxian Wang Q.Daniel Wang Song Wang Tinggui Wang Weiyang Wang Zhongxiang Wang Dandan Xu Haiguang Xu Heng Xu Renxin Xu Xiaojie Xu Yongquan Xue Hang Yang Feng Yuan Shuinai Zhang Yuning Zhang Zhongli Zhang Yuanyuan Zhao Enping Zhou Ping Zhou | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，9： | 1 |

| 8 | Differential protein expression in low-grade astrocytomas and peritumoral human brain tissues显示文摘Differential protein expression between various pathological grades of glioma has been shown in studies of glioma proteomics. However,very little data is available regarding normal brain tissues and glioma differential protein expression,because normal human brain tissues are difficult to harvest. The present study selected samples from low-grade astrocytomas and peritumoral brain tissues to analyze differential protein expression by two-dimensional(2D) electrophoresis and mass spectrometry techniques. Results revealing 36 protein spots by 2D electrophoresis,including 23 spots revealing increased expression and 13 spots revealing decreased expression. However,25 differential proteins were identified by mass spectrometry,including 16 proteins with increased expression and 9 with decreased expression. Western blot analysis confirmed the mass spectrometry results,i.e.,heat shock protein 70(HSP70) and human transthyretin(TTR) expressions were increased,but glial fibrillary acidic protein(GFAP) was decreased,in astrocytomas. The present study constructed a 2D electrophoresis pattern between low-grade astrocytomas in the human brain and peritumoral tissues. Results demonstrated that a majority of differential proteins,such as HSP70,TTR,and GFAP,participate in malignant progression of gliomas. | Guangzhong Xiong Huisheng Xiao Junxian Lu Dongshan Zhang Changlong Bi Li Peng Ge Xiong Li Xiong Ping Chen Songping Liang | 2010 | Neural Regeneration Research2010，5，24： | 0 |

| 10 | Acupoints combination correlates with activation of cerebral areas A functional MRI study显示文摘Acupoint combination is a method used for acupoint treatment of patients.Traditionally,acupoints are matched along the meridian distribution,which is a common rule in clinical practice,but the underlying mechanism remains unclear.Cerebral scans with functional magnetic resonance imaging(fMRI) have been used in the study of acupuncture and acupoint specifically.In this study,fMRI was used to detect the activation of the brain areas under different acupoints,matched along different meridians,to elucidate the acupoint combination via a modern medical approach.Forty healthy volunteers were randomly divided into the following groups:Waiguan point(SJ 5),Waiguan(SJ 5) + Zhigou(SJ 6)(2 acupoints come from the same meridian),Waiguan(SJ 5) + Neiguan(PC 6)(2 acupoints come from 2 meridians with the relationship of interior-exterior),Waiguan(SJ 5) + Yanglingquan(GB 34)(2 acupoints come from 2 meridians with the same name-Shaoyang Meridian),and sham point groups(needling in different points on the right hand).A real-time cerebral fMRI scan was simultaneously performed.The cerebral activation rate,and the number and strength of different regions of interest were compared among the groups.The fMRI cerebral imaging confirmed that there were some differences in the activation of cerebral areas by the needlings in SJ 5,and in combination with other acupoints.Needling at SJ 5 alone greatly activated the right cerebellum,while needling at both SJ 5 and different co-needling points activated different cerebral functional areas. | Xinsheng Lai Yong Huang Chunzhi Tang Junjun Yang Yanqi Zou Junxian Wu Yangjia Lu Renyong Lin | 2011 | Neural Regeneration Research2011，6，9： | 0 |
| 11 | Effects of Seed Soaking with Paclobutrazol on Early Tillering and Endogenous Hormone Contents of Sugarcane Seedlings显示文摘[Objective] The paper was to explore the effect of seed soaking with paclobutrazol( PP333) on early tillering and endogenous hormone content of sugarcane seedlings.[Method] With the sugarcane variety ROC22 as the experimental material,seeds were soaked in different concentrations of PP333. The number and growth of tiller were investigated,and the contents of endogenous hormones IAA,CTK,ABA and GA3 at two-leaf,four-leaf and six-leaf stages of sugarcane seedlings were measured,to study the effects of seed soaking with PP333 on early tillering and endogenous hormone contents of sugarcane seedlings.[Result] Seed soaking with PP333 could effectively improve and advance tillering occurrence of sugarcane seedlings. The suitable PP333 concentration for sugarcane tillering occurrence,growth and development was 50 mg/L. Seed soaking with PP333 significantly increased the CTK and ABA contents in leaves of sugarcane seedlings,and decreased IAA and GA3 contents. [Conclusion]The paper will provide a theoretical basis for application of PP333 in sugarcane production. | Liu Junxian Li Song Tan Fang Xiong Faqian Wang Xiaoman Guo Wenchan Liu Xin He Yibo Wu Kaichao Liu Limin Liu Hongjian Yu Kunxing Dan Ming Lu Manman | 2017 | Plant Diseases and Pests2017，8，1： | 0 |
| 12 | Spatiotemporal hemodynamic monitoring via configurable skin-like microfiber Bragg grating group显示文摘Systemic blood circulation is one of life activity’s most important physiological functions.Continuous noninvasive hemodynamicmonitoring is essential for the management of cardiovascular status.However,it is difficult to achieve systemichemodynamic monitoring with the daily use of current devices due to the lack of multichannel and time-synchronized operationcapability over the whole body.Here,we utilize a soft microfiber Bragg grating group to monitor spatiotemporalhemodynamics by taking advantage of the high sensitivity,electromagnetic immunity,and great temporal synchronizationbetween multiple remote sensor nodes.A continuous systemic hemodynamic measurement technique is developedusing all-mechanical physiological signals,such as ballistocardiogram signals and pulse waves,to illustrate the actualmechanical process of blood circulation.Multiple hemodynamic parameters,such as systemic pulse transit time,heartrate,blood pressure,and peripheral resistance,are monitored using skin-like microfiber Bragg grating patches conformallyattached at different body locations.Relying on the soft microfiber Bragg grating group,the spatiotemporal hemodynamicmonitoring technique opens up new possibilities in clinical medical diagnosis and daily health management. | Hengtian Zhu Junxian Luo Qing Dai Shugeng Zhu Huan Yang Kanghu Zhou Liuwei Zhan Biao Xu Ye Chen Yanqing Lu Fei Xu | 2023 | Opto-Electronic Advances2023，6，11： | 0 |
