| 1 | Myelin Oligodendrocyte Glycoprotein-IgG Contributes to Oligodendrocytopathy in the Presence of Complement, Distinct from Astrocytopathy Induced by AQP4-IgG显示文摘Immunoglobulin G against myelin oligodendrocyte glycoprotein(MOG-Ig G) is detectable in neuromyelitis optica spectrum disorder(NMOSD) without aquaporin-4 Ig G(AQP4-Ig G), but its pathogenicity remains unclear.In this study, we explored the pathogenic mechanisms of MOG-Ig G in vitro and in vivo and compared them with those of AQP4-Ig G. MOG-Ig G-positive serum induced complement activation and cell death in human embryonic kidney(HEK)-293 T cells transfected with human MOG. In C57 BL/6 mice and Sprague-Dawley rats, MOG-Ig G only caused lesions in the presence of complement. Interestingly, AQP4-Ig G induced astroglial damage, while MOGIg G mainly caused myelin loss. MOG-Ig G also induced astrocyte damage in mouse brains in the presence ofcomplement. Importantly, we also observed ultrastructural changes induced by MOG-Ig G and AQP4-Ig G. These findings suggest that MOG-Ig G directly mediates cell death by activating complement in vitro and producing NMOSDlike lesions in vivo. AQP4-Ig G directly targets astrocytes,while MOG-Ig G mainly damages oligodendrocytes. | Ling Fang Xinmei Kang Zhen Wang Shisi Wang Jingqi Wang Yifan Zhou Chen Chen Xiaobo Sun Yaping Yan Allan G.

| 2 | Scutellaria baicalensis stem-leaf total flavonoid reduces neuronal apoptosis induced by amyloid beta-peptide (25-35)显示文摘Scutellaria baicalensis stem-leaf total flavonoid might attenuate learning/memory impairment and neuronal loss in rats induced by amyloid beta-peptide. This study aimed to explore the effects of Scutellaria baicalensis stem-leaf total flavonoid on amyloid beta-peptide-induced neuronal apoptosis and the expression of apoptosis-related proteins in the rat hippocampus. Male Wistar rats were given intragastric administration of Scutellaria baicalensis stem-leaf total flavonoid, 50 or 100 mg/kg, once per day. On day 8 after administration, 10 μg amyloid beta-peptide (25-35) was injected into the bilateral hippocampus of rats to induce neuronal apoptosis. On day 20, hippocampal tissue was harvested and probed with the terminal deoxyribonucleotidyl transferase-mediated biotin-16-dUTP nick-end labeling assay. Scutellaria baicalensis stem-leaf total flavonoid at 50 and 100 mg/kg reduced neuronal apoptosis induced by amyloid beta-peptide (25-35 in the rat hippocampus. Immunohistochemistry and western blot assay revealed that expression of the pro-apoptotic protein Bax, cytochrome c and caspase-3 was significantly diminished by 50 and 100 mg/kg Scutellaria baicalensis stem-leaf total flavonoid, while expression of the anti-apoptotic protein Bcl-2 was increased. Moreover, 100 mg/kg Scutellaria baicalensis stem-leaf total flavonoid had a more dramatic effect than the lower dosage. These experimental findings indicate that Scutellaria baicalensis stem-leaf total flavonoid dose-dependently attenuates neuronal apoptosis induced by amyloid beta-peptide in the hippocampus, and it might mediate this by regulating the expression of Bax, cytochrome c, caspase-3 and Bcl-2. | Ruiting Wang Xingbin Shen Enhong Xing Lihua Guan Lisheng Xin | 2013 | Neural Regeneration Research2013,8,12: | 8 |
| 3 | KAI1/CD82 suppresses hepatocyte growth factorinduced migration of hepatoma cells via upregulationof Sprouty2显示文摘We conducted a study concerning the suppressive mechanism of KAI1/CD82 on hepatoma cell metastasis.Hepatocyte growth factor(HGF)induces the migration of hepatoma cells through activation of cellular sphingosine kinase 1(SphK1).Adenovirus-mediated gene transfer of KAI1(Ad-KAI1)downregulates the SphK1 expression and suppresses the HGF-induced migration of SMMC-7721 human hepatocellcular carcinoma cells.Overexpression of KAI1/CD82 significantly elevates Sprouty2 at the protein level.Ablation of Sprouty2 with RNA interference can block the KAI1/CD82-induced suppression of hepatoma cell migration and downregulation of SphK1 expression.It is demonstrated that KAI1/CD82 suppresses HGF-induced migration of hepatoma cells via upregulation of Sprouty2. | MU ZhenBin1 ,3,WANG Hua 2,ZHANG Jing 2,LI QingFang 2,WANG LiSheng 2&GUO XiaoZhong 3 1State Key Laboratory of Cancer Biology and Institute of Digestive Diseases,Xijing Hospital,Fourth Military Medical University,Xi’an 710032,China 2Department of Experimental Hematology,Beijing Institute of Radiation Medicine,Beijing 100850,China 3Department of Gastroenterology,Shenyang General Hospital of PLA,Shenyang 110016,China | 2008 | Science China(Life Sciences)2008,51,7: | 7 |
| 4 | A review of friction stir joining of SiCp/Al composites显示文摘SiCp/Al composites have excellent comprehensive properties and have been widely used in aerospace,automotive industry and other fields.Due to the huge difference in performance between SiC particles and matrix alloys,traditional fusion welding methods are difficult to meet the join requirements of SiCp/Al composites.Friction stir joining(friction stir welding),as a solid phase joining process,has been proved to be a new technology with fine prospect in joining SiCp/Al composites compared with fusion welding process.Although some progress has been made in recent years,there are still full of challenges.In this paper,the research status of friction stir joining of SiCp/Al composites in recent years is expatiated,including the weldability of SiCp/Al composites,the macrostructure and the microstructure of joints,mechanical properties of joints,and tool wear and monitoring.Furthermore,the existing challenges of friction stir joining of SiCp/Al composites are summarized and the future development directions are prospected. | Lisheng ZUO Xianrui ZHAO Zeyang LI Dunwen ZUO Hongfeng WANG | 2020 | Chinese Journal of Aeronautics2020,33,3: | 6 |

| 6 | Rare-earth element geochemistry reveals the provenance of sediments on the southwestern margin of the Challenger Deep显示文摘The hadal zone represents one of the last great frontiers in modern marine science,and deciphering the provenance of sediment that is supplied to these trench settings remains a largely unanswered question.Here,we examine the mineralogical and geochemical composition of a sediment core(core CD-1)that was recovered from the southwestern margin of the Challenger Deep within the Mariana Trench.Major element abundances and rare-earth element patterns from these sediments require inputs from both terrigenous dust and locally sourced volcanic debris.We exploit a two-endmember mixing model to demonstrate that locally sourced volcanic material dominates the sediment supply to the Challenger Deep(averaging^72%).The remainder,however,is supplied by aeolian dust(averaging^28%),which is consistent with adjacent studies that utilized Sr-Nd isotopic data.Building on a growing database,we strengthen our understanding of Asian aeolian dust input into the northwestern Pacific,which ultimately improves our appreciation of sedimentation in,and around,the hadal zone. | JIANG Zuzhou SUN Zhilei LIU Zhaoqing CAO Hong GENG Wei XU Haixia WANG Lisheng WANG Libo | 2019 | Journal of Oceanology and Limnology2019,37,3: | 5 |
| 7 | Human RBCs blood group conversion from A to O using a novel α-N-acetylgalactosaminidase of high specific activity显示文摘α-N-acetylgalactosaminidase (αNAGA) can convert group A human red blood cells (RBCs) to group O. One novel αNAGA gene was cloned by PCR from Elizabethkingia meningosepticum isolated from a domestic clinical sample. Pure recombinant αNAGA was obtained by genetic engineering and protein purification with a calculated molecule of 49.6 kD. αNAGA was selective for terminal α-N-acetylgalacto-samine residue with a high specific activity. αNAGA could completely remove A antigens of 1 U (about 100 mL) group A1 or A2 RBCs in 1 h at pH 6.8 and 25℃ with a consumption of 1.5 or 0.4 mg recombinant enzyme. Enzyme-converted group A RBCs did not agglutinate after being mixed with monoclonal anti-A or sera of groups A,B,AB and O. Other blood group antigens except ABO had no change. FCM analy-sis showed that A antigens and A1 antigens disappeared while H antigens increased. It indicated that αNAGA successfully converted human blood group A RBCs to universally transfusable group O RBCs without the risk of ABO-incompatible transfusion reactions. This αNAGA was suitable for producing universal RBCs to increase clinical transfusion safety,improve the RBCs supply,and to decrease transfusion cost and support transfusion service in case of emergency. | YU ChengYu XU Hua WANG LiSheng ZHANG JianGeng ZHANG YangPei | 2008 | Chinese Science Bulletin2008,53,13: | 5 |
| 8 | Solubilities of 1-Methyl-3-(3-sulfopropyl)-imidazolium Hydrogen Sulfate in Selected Solvents显示文摘Ionic liquid 1-methyl-3-(3-sulfopropyl) -imidazolium hydrogen sulfate([C3SO3HMIM][HSO4]) was synthesized and characterized by infrared spectroscopy(IR) ,nuclear magnetic resonance(1H and 13C NMR) and ultraviolet-visible(UV-Vis) spectra.

| 9 | Association of the HTR2C-759CT polymorphism and antipsychotic-induced weight gain:a meta-analysis显示文摘Background Antipsychotic-induced weight gain(AIWG)is a crucial factor for the medication cessation of patients with schizophrenia.Multiple studies have shown that the functional polymorphism-759 C/T(rs3813929)in the HTR2C promoter region could possibly be correlated with AIWG.Aim To evaluate the genetic association of the HTR2C-759C/T polymorphism and AIWG in patients with schizophrenia with antipsychotic drugs(APDs)administration.Methods Eligible studies were identified by searching the following databases:PubMed,Embase,Web of Science,China Nation Knowledge Infrastructure(CNKI),VIP,Wanfang Data,Chinese Biomedical Literature Database(CBM)and the Airiti Library.The quality of studies was evaluated based on the Newcastle-Ottawa Scale.The pooled OR and 95%Cl were calculated for the dominant(CT/TT/T vs CC/C)mode,and subgroup analyses were performed based on ethnicity,antipsychotic medication and gender;ail statistical analyses were performed using the statistical software STATA V.12.0.Result A total of 17 studies with 3170 patients with schizophrenia were included in our meta-analysis.The result of the meta-analysis has shown that the association between the-759 C/T polymorphism and AIWG is statistically significant(OR 0.34,95%Cl:0.20 to 0.57,z=4.11,p<0.001).The subgroup analyses revealed significant correlations between the-759 C/T polymorphism and AIWG in the Caucasian population(OR 0.33,95%CI:0.14 to 0.77,z=2.55,p=0.011),the Asian population(OR 0.31,95%Cl:0.18 to 0.52,z=4.46,p<0.001),the patients with APDs administration(CT/JTfJ vs CC/C:OR 0.63,95%Cl:0.40 to 1.00,z=1.97,p=0.049)and the patients with atypical antipsychotic drug administration(CT/TT/T vs CC/C:OR 0.21,95%Cl:0.09 to 0.47,z=3.83,p<0.001).The sensitivity analysis showed that the results were stable.Begg's test(after correction z=1.07,p=0.287)and Egger's test(t=-2.41,p=0.029)show that the included articles have no significant publication bias.Conclusion There is a significant genetic association between HTR2C-759C/T and AIWG,and patients with T allele are less likely to have AIWG. | Yan Chen Yewei Wang Xinyu Fang Yi Zhang Lisheng Song Chen Zhang | 2020 | General Psychiatry2020,33,3: | 4 |
| 10 | Extended Range(10–30 Days) Heavy Rain Forecasting Study Based on a Nonlinear Cross-Prediction Error Model显示文摘Extended range(10–30 d) heavy rain forecasting is difficult but performs an important function in disaster prevention and mitigation. In this paper,a nonlinear cross prediction error(NCPE) algorithm that combines nonlinear dynamics and statistical methods is proposed. The method is based on phase space reconstruction of chaotic single-variable time series of precipitable water and is tested in 100 global cases of heavy rain. First,nonlinear relative dynamic error for local attractor pairs is calculated at different stages of the heavy rain process,after which the local change characteristics of the attractors are analyzed. Second,the eigen-peak is defined as a prediction indicator based on an error threshold of about 1.5,and is then used to analyze the forecasting validity period. The results reveal that the prediction indicator features regarded as eigenpeaks for heavy rain extreme weather are all reflected consistently,without failure,based on the NCPE model; the prediction validity periods for 1–2 d,3–9 d and 10–30 d are 4,22 and 74 cases,respectively,without false alarm or omission. The NCPE model developed allows accurate forecasting of heavy rain over an extended range of 10–30 d and has the potential to be used to explore the mechanisms involved in the development of heavy rain according to a segmentation scale. This novel method provides new insights into extended range forecasting and atmospheric predictability,and also allows the creation of multi-variable chaotic extreme weather prediction models based on high spatiotemporal resolution data. | XIA Zhiye CHEN Hongbin XU Lisheng WANG Yongqian | 2015 | Advances in Atmospheric Sciences2015,32,12: | 4 |
| 11 | Re-evaluating the role of epithelial-mesenchymal-transition in cancer progression显示文摘Epithelial-mesenchymal transition(EMT) and mesenchymal-epithelial transition(MET) are essential for embryonic development and also important in cancer progression. In a conventional model, epithelial-like cancer cells transit to mesenchymal-like tumor cells with great motility via EMT transcription factors; these mesenchymallike cells migrate through the circulation system, relocate to a suitable site and then convert back to an epithelial-like phenotype to regenerate the tumor. However, recent findings challenge this conventional model and support the existence of a stable hybrid epithelial/mesenchymal(E/M) tumor population. Hybrid E/M tumor cells exhibit both epithelial and mesenchymal properties, possess great metastatic and tumorigenic capacity and are associated with poorer patient prognosis. The hybrid E/M model and associated regulatory networks represent a conceptual change regarding tumor metastasis and organ colonization. It may lead to the development of novel treatment strategies to ultimately stop cancer progression and improve disease-free survival. | Andrew Sulaiman Zemin Yao Lisheng Wang | 2018 | The Journal of Biomedical Research2018,32,2: | 4 |
| 12 | Effect of stimulating the acupoints Feishu (BL 13) and Dazhui (GV14) on transdermal uptake of sinapine thiocyanate in asthma gel显示文摘OBJECTIVE: To investigate the effect of stimulating the acupoints Feishu(BL 13) and Dazhui(GV 14) on the transdermal uptake of sinapine thiocyanate contained in a gel used for the management of asthma.METHODS: Thirty Sprague-Dawley rats were randomly divided into three equal groups using a random number table: the Feishu(BL 13) acupoint group, the Dazhui(GV 14) acupoint group, and the nonacupoint group or control group. Using micro-dialysis technology, preprocessed skin probes were implanted into the rats at Feishu(BL 13), Dazhui(GV 14), and a nonacupoint site. Asthma gel was then placed on the skin at Feishu(BL 13), Dazhui(GV14) acupoints, and the nonacupoint for all groups.Dialysate was collected every 30 min for 12 h. The normalized concentration of sinapine thiocyanate in the skin was determined by high-performance liquid chromatography.RESULTS: The rat in vivo transdermal experiment demonstrated that the quantity-time equation showed a good linear correlation with zero-order kinetics(r > 0.99). The transdermal behavior was in accordance with the first-order rate open model in which the transdermal penetration rates and the accumulative amounts of sinapine thiocyanate in the skin at the acupoint sites were greater than those through the skin of the nonacupoint site. The systemic maximum concentration and the area under the curve of sinapine thiocyanate in the acupoint groups were significantly greater than in the nonacupoint group. A lag time was observed in both acupoint groups, but not in the nonacupoint group.CONCLUSION: Stimulating the acupoints promotes the percutaneous absorption of sinapine thiocyanate and also controls its release, reducing concentration fluctuations in the blood. | Fan Wentao Huang Yuwei Wang Lisheng Liao Weiguo Li Zhou Wu Yinai Liao Fengyun Yu Jianye Liu Qiang | 2017 | Journal of Traditional Chinese Medicine2017,37,4: | 3 |

| 14 | Drop casting based superhydrophobic and electrically conductive coating for high performance strain sensing显示文摘Conductive polymer composites(CPCs)strain sensors exhibit promising applications in flexible electronics,people’s health monitoring,etc.It remains a big challenge to develop a simple and cost-effective method to prepare CPCs with high conductivity,corrosion resistance,strong interfacial adhesion and high sensitivity.Here,we propose a facile“drop-casting and fluorination”strategy to fabricate superhydrophobic and highly electrically conductive coating by Ag precursor adsorption onto a commercially available elastic tape,subsequent chemical reduction and final fluorination.The Ag nanoparticles could not only construct the electrically conductive network but also greatly enhance the surface roughness.The contact angle and electrical conductivity of the coating can reach as high as 156°and 126 S/cm,respectively.When used for strain sensing,the superhydrophobic and conductive coating shows a high gauger factor(up to 7631 with the strain from 44%to 50%)and outstanding recyclability.The strain sensor could monitor different body joint motions with the stable and reliable sensing signals even after long time treatment in a corrosive solution. | Ling Wang Lisheng Wu Yuqing Wang Junchen Luo Huaiguo Xue Jiefeng Gao | 2022 | Nano Materials Science2022,4,2: | 2 |
| 15 | Polymorph and morphology of CaCO_3 in relation to precipitation conditions in a bubbling system显示文摘Simulating the typical carbonation step in a mineral CO_2 sequestration, precipitated calcium carbonate(PCC) was prepared by bubbling CO_2 gas into a rich Ca solution. These carbonation reactions were conducted at three p H ranges, namely 10.0–9.0, 9.0–8.0, and 8.0–7.0, in which temperature and CO_2 flow rate are additional experimental variables. The PCC obtained in experiments was examined by Fourier transform infrared spectroscopy(FTIR)and X-ray diffraction(XRD). It was found that supersaturation determined by p H value and flow rate of CO_2 has significant influence on polymorph of PCC. Vaterite was preferably formed at high supersaturation, while dissolution of metastable vaterite and crystallization of calcite occurred at low supersaturation. High temperature is a critical factor for the formation of aragonite. At 70 °C, vaterite, calcite and aragonite were observed to coexist in PCC because transformation from vaterite to aragonite via calcite occurred at this temperature. Scanning electron microscopy(SEM) technology was performed on prepared PCC, and various morphologies consistent with polymorphs were observed. | Jian Sun Lisheng Wang Dongfang Zhao | 2017 | Chinese Journal of Chemical Engineering2017,25,9: | 2 |

| 17 | The association of grip strength with cardiovascular diseases and all-cause mortality in people with hypertension:Findings from the Prospective Urban Rural Epidemiology China Study显示文摘Background:Both hypertension and grip strength(GS)are predictors of mortality and cardiovascular disease(CVD),but whether these risk factors interact to affect CVD and all-cause mortality is unknown.This study sought to investigate the associations of GS with the risk of major CVD incidence,CVD mortality,and all-cause mortality in patients with hypertension.Methods:GS was measured using a Jamar dynamometer(Sammons Preston,Bolingbrook,IL,USA)in participants aged 3570 years from 12 provinces included in the Prospective Urban Rural Epidemiology China Study.Cox frailty proportional hazards models were used to examine the associations of GS and hypertension and the outcomes of all-cause mortality and CVD incidence/mortality.Results:Among 39,862 participants included in this study,15,964 reported having hypertension,and 9095 had high GS at baseline.After a median follow-up of 8.9 years(interquartile range,6.79.9 years),1822 participants developed major CVD,and 1250 deaths occurred(388 as a result of CVD).Compared with normotensive participants with high GS,hypertensive patients with high GS had a higher risk of major CVD incidence(hazard ratio(HR)=2.39;95%confidence interval(95%CI):1.863.06;p<0.001)or CVD mortality(HR=3.11;95%CI:1.596.06;p<0.001)but did not have a significantly increased risk of all-cause mortality(HR=1.24;95%CI:0.921.68;p=0.159).These risks were further increased if hypertensive participants whose GS level was low(major CVD incidence,HR=3.31,95%CI:2.604.22,p<0.001;CVD mortality,HR=4.99,95%CI:2.649.43,p<0.001;and all-cause mortality,HR=1.93,95%CI:1.472.53,p<0.001).Conclusion:The present study demonstrates that low GS is associated with the highest risk of major CVD incidence,CVD mortality,and all-cause mortality among hypertensive patients.High levels of GS appear to mitigate long-term mortality risk among hypertensive patients. | Weida Liu Darryl P Leong Bo Hu Lap AhTse Sumathy Rangarajan Yang Wang Chuangshi Wang Fanghong Lu Yindong Li Salim Yusuf Lisheng Liu Wei Li | 2021 | Journal of Sport and Health Science2021,10,6: | 2 |
| 18 | Noninvasive Ultrasound Stimulation of Ventral Tegmental Area Induces Reanimation from General Anaesthesia in Mice显示文摘Evidence in animals suggests that deep brain stimulation or optogenetics can be used for recovery from disorders of consciousness(DOC).However,these treatments require invasive procedures.This report presents a noninvasive strategy to stimulate central nervous system neurons selectively for recovery from DOC in mice.Through the delivery of ultrasound energy to the ventral tegmental area,mice were aroused from an unconscious,anaesthetized state in this study,and this process was controlled by adjusting the ultrasound parameters.The mice in the sham group under isoflurane-induced,continuous,steady-state general anaesthesia did not regain their righting reflex.On insonation,the emergence time from inhaled isoflurane anaesthesia decreased(sham.13.63±0.53 min,ultrasound.1.5±0.19 min,p<0.001).Further,the induction time(sham.12.0±0.6 min,ultrasound.17.88±0.64 min,p<0.001)and the concentration for 50%of the maximal effect(EC50)of isoflurane(sham.0.6%,ultrasound.0.7%)increased.In addition,ultrasound stimulation reduced the recovery time in mice with traumatic brain injury(sham.30.38±1.9 min,ultrasound.7.38±1.02 min,p<0.01).This noninvasive strategy could be used on demand to promote emergence from DOC and may be a potential treatment for such disorders. | Tianyuan Bian Wen Meng Meihong Qiu Zhigang Zhong Zhengrong Lin Junjie Zou Yibo Wang Xiaowei Huang Lisheng Xu Tifei Yuan Zhili Huang Lili Niu Long Meng Hairong Zheng | 2021 | Research2021,,1: | 2 |
| 19 | Understanding the mechanism of social tie in the propagation process of social network with communication channel显示文摘The propagation of information in online social networks plays a critical role in modern life,and thus has been studied broadly.Researchers have proposed a series of propagation models,generally,which use a single transition probability or consider factors such as content and time to describe the way how a user activates her/his neighbors.However,the research on the mechanism how social ties between users play roles in propagation process is still limited.Specifically,comprehensive summary of factors which affect user’s decision whether to share neighbor’s content was lacked in existing works,so that the existing models failed to clearly describe the process a user be activated by a neighbor.To this end,in this paper,we analyze the close correspondence between social tie in propagation process and communication channel,thus we propose to exploit the communication channel to describe the information propagation process between users,and design a social tie channel(STC)model.The model can naturally incorporate many factors affecting the information propagation through edges such as content topic and user preference,and thus can effectively capture the user behavior and relationship characteristics which indicate the property of a social tie.Extensive experiments conducted on two real-world datasets demonstrate the effectiveness of our model on content sharing prediction between users. | Kai LI Guangyi LV Zhefeng WANG Qi LIU Enhong CHEN Lisheng QIAO | 2019 | Frontiers of Computer Science2019,13,6: | 2 |
