| 2 | 粉防己碱抑制前列腺癌细胞迁移和侵袭并通过诱导凋亡抑制细胞增殖显示文摘粉防己碱作为一种传统的中药,在多种肿瘤细胞中呈现显著的抗肿瘤活性。然而,粉防己碱在前列腺癌细胞中的作用却知之甚少,且其作用于前列腺癌的具体机制也尚未有人阐述。为了探究粉防己碱对前列腺癌DU145和PC-3两种细胞系生长抑制、凋亡诱导、迁移和侵袭抑制等方面的作用,通过MTT实验和克隆形成实验检测其对前列腺癌细胞的生长抑制能力,采用流式细胞仪检测其对前列腺癌细胞的凋亡诱导作用。后通过Western blotting实验检测粉防己碱处理后两种前列腺癌细胞系中PARP、Caspase-3、Akt、p-Akt、Bcl-2、Bax等蛋白的表达情况。而细胞划痕实验和transwell侵袭实验则分别用来检测粉防己碱对前列腺癌细胞的迁移和侵袭能力。结果显示,粉防己碱可剂量依赖性和时间依赖性地抑制前列腺癌细胞系DU145和PC-3的生长;且经粉防己碱处理后,两种前列腺癌细胞系的细胞克隆数明显受到抑制。且粉防己碱可抑制两种前列腺癌细胞系的侵袭,并显著抑制其迁移能力。由此可知,粉防己碱对前列腺癌细胞的增殖、迁移和侵袭有显著抑制作用。另外,粉防己碱可剂量依赖性地诱导前列腺癌细胞的凋亡,且此过程是通过caspase级联反应的激活和PI3K-Akt信号通路的抑制而得以实现的。上述结果提示粉防己碱在临床中可作为前列腺癌治疗的一种潜在治疗药物。 | Wei Liu Bo KOU Zhen-Kun Ma Xiao-Shuang Tang Chuan Lv Min Ye Jia-Qi Chen Lei Li Xin-Yang Wang Da-Lin He | 2015 | Asian Journal of Andrology2015，17，5： | 18 |

| 4 | The Impacts of Mosquito Density and Meteorological Factors on Dengue Fever Epidemics in Guangzhou, China, 2006-2014: a Time-series Analysis显示文摘Objective To explore the associations between the monthly number of dengue fever(DF) cases and possible risk factors in Guangzhou, a subtropical city of China. Methods The monthly number of DF cases, Breteau Index(BI), and meteorological measures during 2006-2014 recorded in Guangzhou, China, were assessed. A negative binomial regression model was used to evaluate the relationships between BI, meteorological factors, and the monthly number of DF cases. Results A total of 39,697 DF cases were detected in Guangzhou during the study period. DF incidence presented an obvious seasonal pattern, with most cases occurring from June to November. The current month's BI, average temperature(Tave), previous month's minimum temperature(Tmin), and Tave were positively associated with DF incidence. A threshold of 18.25 °C was found in the relationship between the current month's Tmin and DF incidence. Conclusion Mosquito density, Tave, and Tmin play a critical role in DF transmission in Guangzhou. These findings could be useful in the development of a DF early warning system and assist in effective control and prevention strategies in the DF epidemic. | SHEN Ji Chuan LUO Lei LI Li JING Qin Long OU Chun Quan YANG Zhi Cong CHEN Xiao Guang | 2015 | Biomedical and Environmental Sciences2015，28，5： | 12 |
| 5 | ATF3 contributes to brucine-triggered glioma cell ferroptosis via promotion of hydrogen peroxide and iron显示文摘Ferroptotic cell death is characterized by iron-dependent lipid peroxidation that is initiated by ferrous iron and H_(2)O_(2) via Fenton reaction,in which the role of activating transcription factor 3(ATF3)remains elusive.Brucine is a weak alkaline indole alkaloid extracted from the seeds of Strychnos nux-vomica,which has shown potent antitumor activity against various tumors,including glioma.In this study,we showed that brucine inhibited glioma cell growth in vitro and in vivo,which was paralleled by nuclear translocation of ATF3,lipid peroxidation,and increases of iron and H_(2)O_(2).Furthermore,brucine-induced lipid peroxidation was inhibited or exacerbated when intracellular iron was chelated by deferoxamine(500μM)or improved by ferric ammonium citrate(500μM).Suppression of lipid peroxidation with lipophilic antioxidants ferrostatin-1(50μM)or liproxstatin-1(30μM)rescued brucine-induced glioma cell death.Moreover,knockdown of ATF3 prevented brucine-induced accumulation of iron and H_(2)O_(2) and glioma cell death.We revealed that brucine induced ATF3 upregulation and translocation into nuclei via activation of ER stress.ATF3 promoted brucine-induced H_(2)O_(2) accumulation via upregulating NOX4 and SOD1 to generate H_(2)O_(2) on one hand,and downregulating catalase and xCT to prevent H_(2)O_(2) degradation on the other hand.H_(2)O_(2) then contributed to brucine-triggered iron increase and transferrin receptor upregulation,as well as lipid peroxidation.This was further verified by treating glioma cells with exogenous H_(2)O_(2) alone.Moreover,H_(2)O_(2) reversely exacerbated brucine-induced ER stress.Taken together,ATF3 contributes to brucine-induced glioma cell ferroptosis via increasing H_(2)O_(2) and iron. | Shan Lu Xuan-zhong Wang Chuan He Lei Wang Shi-peng Liang Chong-cheng Wang Chen Li Tian-fei Luo Chun-sheng Feng Zhen-chuan Wang Guang-fan Chi Peng-fei Ge | 2021 | Acta Pharmacologica Sinica2021，42，10： | 10 |
| 6 | Serum 25-hydroxyvitamin D deficiency predicts poor outcomes among acute ischemic stroke patients receiving intravenous thrombolysis显示文摘To the Editor:Ischemic stroke remains a major cause of death and disability worldwide and contributes to the rising costs of health care.Thrombolytic therapy with tissue plasminogen activator (tPA,alteplase)is beneficial for the treatment of acute ischemic stroke.However,only 40%to 50%of stroke patients show a significant improvement after treatment.In addition,the use of alteplase is restricted because symptomatic intracranial hemorrhase (slCH)occurs in 1.7%to 6.4%of treated patients.[1] 25-hydroxyvitamin D (25(OH)D),which is the major circulating metabolite of vitamin D,has been confirmed to be closely related to cerebrovascular disease (CVD).A series of studies indicated that vitamin D deficiency was associated with an increased risk of ischemic stroke,high stroke severity and poor functional outcomes. | Lei Wei Chuan Chen Yong-Qiang Dai Li Ding Hai-Yan Li Yan-Jun Lin Hao-Tian WU Zhen WU Zheng-Qi Lu | 2019 | Chinese Medical Journal2019，，4： | 9 |
| 7 | Ultrasound-Assisted Transient Liquid Phase Bonding of Magnesium Alloy Using Brass Interlayer in Air显示文摘The microstructure evolution and oxide film behavior in ultrasound-assisted transient liquid phase(U-TLP) bonding of Mg alloy were investigated by applying different ultrasonic time at 460?C with brass interlayer in air. The results indicated that with increasing ultrasonic time, brass interlayer disappeared gradually and the Mg-Cu-Zn eutectic compounds were formed. The eutectic compounds in the joint decreased as the ultrasonic time increased further. The oxide removal process was divided into four steps. Continuous oxide film at the interface was partially fractured by ultrasonic vibration,and then suspended into liquid by undermining eutectic reaction. After that, the suspended oxide film was broken into small oxide fragments by ultrasonic cavitation effect, which was finally squeezed out of the joint by ultrasonic squeeze action. In addition, the mechanical properties of the joints were investigated. The maximum shear strength of the joint reached 105 MPa, which was 100% of base metal. | Zhiwei Lai Ruishan Xie Chuan Pan Xiaoguang Chen Lei Liu Wenxian Wang Guisheng Zou | 2017 | Journal of Materials Science & Technology2017，33，6： | 7 |
| 8 | FOXO3a protects glioma cells against temozolomide-induced DNA double strand breaks via promotion of BNIP3-mediated mitophagy显示文摘FOXO3a(forkhead box transcription factor 3a)is involved in regulating multiple biological processes in cancer cells.BNIP3(Bcl-2/adenovirus E1B 19-kDa-interacting protein 3)is a receptor accounting for priming damaged mitochondria for autophagic removal.In this study we investigated the role of FOXO3a in regulating the sensitivity of glioma cells to temozolomide(TMZ)and its relationship with BNIP3-mediated mitophagy.We showed that TMZ dosage-dependently inhibited the viability of human U87,U251,T98G,LN18 and rat C6 glioma cells with IC_(50) values of 135.75,128.26,142.65,155.73 and 111.60μM,respectively.In U87 and U251 cells,TMZ(200μM)induced DNA double strand breaks(DSBs)and nuclear translocation of apoptosis inducing factor(AIF),which was accompanied by BNIP3-mediated mitophagy and FOXO3a accumulation in nucleus.TMZ treatment induced intracellular ROS accumulation in U87 and U251 cells via enhancing mitochondrial superoxide,which not only contributed to DNA DSBs and exacerbated mitochondrial dysfunction,but also upregulated FOXO3a expression.Knockdown of FOXO3a aggravated TMZ-induced DNA DSBs and mitochondrial damage,as well as glioma cell death.TMZ treatment not only upregulated BNIP3 and activated autophagy,but also triggered mitophagy by prompting BNIP3 translocation to mitochondria and reinforcing BNIP3 interaction with LC3BII.Inhibition of mitophagy by knocking down BNIP3 with SiRNA or blocking autophagy with 3MA or bafilomycin A1 exacerbated mitochondrial superoxide and intracellular ROS accumulation.Moreover,FOXO3a knockdown inhibited TMZ-induced BNIP3 upregulation and autophagy activation.In addition,we showed that treatment with TMZ(100 mg·kg^(-1)·d^(-1),ip)for 12 days in C6 cell xenograft mice markedly inhibited tumor growth accompanied by inducing FOXO3a upregulation,oxidative stress and BNIP3-mediated mitophagy in tumor tissues.These results demonstrate that FOXO3a attenuates temozolomide-induced DNA double strand breaks in human glioma cells via promoting BNIP3-mediated mitophagy. | Chuan He Shan Lu Xuan-zhong Wang Chong-cheng Wang Lei Wang Shi-peng Liang Tian-fei Luo Zhen-chuan Wang Mei-hua Piao Guang-fan Chi Peng-fei Ge | 2021 | Acta Pharmacologica Sinica2021，42，8： | 7 |

| 13 | Aboveground biomass and its spatial distribution pattern of herbaceous marsh vegetation in China显示文摘Herbaceous marsh is the most widely distributed type of marsh wetland ecosystem,and has important ecological functions such as water conservation,climate regulation,carbon storage and fixation,and sheltering rare species.The carbon sequestration function of herbaceous marsh plays a key role in slowing climate warming and maintaining regional environmental stability.Vegetation biomass is an important index reflecting the carbon sequestration capacity of wetlands.Investigating the biomass of marsh vegetation can provide a scientific basis for estimating the carbon storage and carbon sequestration capacity of marshes.Based on field survey data of aboveground biomass of herbaceous marsh vegetation and the distribution data set of marsh in China,we analyzed the aboveground biomass and its spatial distribution pattern of herbaceous marsh on a national scale for the first time.The results showed that in China the total area of herbaceous marsh was 9.7×10^(4) km^(2),the average density of aboveground biomass of herbaceous marsh vegetation was 227.5±23.0 g C m-2(95%confidence interval,the same below),and the total aboveground biomass was 22.2±2.2 Tg C(1 Tg=1012 g).The aboveground biomass density of herbaceous marsh vegetation is generally low in Northeast China and the Tibetan Plateau,and high in central North China and coastal regions in China.In different marsh distribution regions of China,the average biomass density of herbaceous marsh vegetation from small to large was as follows:temperate humid and semi-humid marsh region(182.3±49.3 g C m^(-2)) | Xiangjin SHEN Ming JIANG Xianguo LU Xingtu LIU Bo LIU Jiaqi ZHANG Xianwei WANG Shouzheng TONG Guangchun LEI Shengzhong WANG Chuan TONG Hangqing FAN Kun TIAN Xiaolong WANG Yuanman HU Yonghong XIE Muyuan MA Shuwen ZHANG Chunxiang CAO Zhichen WANG | 2021 | Science China Earth Sciences2021，64，7： | 4 |

| 15 | SARS-CoV-2 infection aggravates chronic comorbidities of cardiovascular diseases and diabetes in mice显示文摘Background:Cardiovascular diseases(CVDs)and diabetes mellitus(DM)are top two chronic comorbidities that increase the severity and mortality of COVID-19.However,how SARS-CoV-2 alters the progression of chronic diseases remain unclear.Methods:We used adenovirus to deliver h-ACE2 to lung to enable SARS-CoV-2 infection in mice.SARS-CoV-2’s impacts on pathogenesis of chronic diseases were studied through histopathological,virologic and molecular biology analysis.Results:Pre-existing CVDs resulted in viral invasion,ROS elevation and activation of apoptosis pathways contribute myocardial injury during SARS-CoV-2 infection.Viral infection increased fasting blood glucose and reduced insulin response in DM model.Bone mineral density decreased shortly after infection,which associated with impaired PI3K/AKT/mTOR signaling.Conclusion:We established mouse models mimicked the complex pathological symptoms of COVID-19 patients with chronic diseases.Pre-existing diseases could impair the inflammatory responses to SARS-CoV-2 infection,which further aggravated the pre-existing diseases.This work provided valuable information to better understand the interplay between the primary diseases and SARS-CoV-2 infection. | Yuanwu Ma Dan Lu Linlin Bao Yajin Qu Jiangning Liu Xiaolong Qi Lei Yu Xu Zhang Feifei Qi Qi Lv Yunpeng Liu Xudong Shi Caixian Sun Jing Li Jie Wang Yunlin Han Kai Gao Wei Dong Ning Liu Shan Gao Jing Xue Qiang Wei Sidan Pan Hong Gao Lianfeng Zhang Chuan Qin | 2021 | Animal Models and Experimental Medicine2021，4，1： | 3 |
| 16 | Association Mapping and Marker Development of Genes forStarch Lysophospholipid Synthesis in Rice显示文摘Phospholipids are a major kind of lipids in rice grains and have fundamental nutritional and functional benefits to the plant. Their lyso forms(lysophospholipids, LPLs) often form inclusion complexes with amylose or independently influence the physicochemical and functional properties of rice starch. However, the genetic basis for LPL synthesis in rice endosperm is largely unknown. Here, we performed a preliminary association test of 13 LPL compositions among 20 rice accessions, and identified 22 putative main-effect quantitative trait loci responsible for all LPLs except for LPC14:0 and LPE14:0. Five derived cleaved amplified polymorphic sequences and one insertion/deletion marker for three LPL-synthesis-related candidate genes were developed. Association analysis revealed two markers significantly associated with starch LPL traits. These results provide an insight into the genetic basis of phospholipid biosynthesis in rice and may contribute to the rice quality breeding programs using functional markers. | TONG Chuan LIU Lei Daniel L.E.WATERS BAO Jin-song | 2016 | Rice science2016，23，6： | 3 |
| 17 | A dynamic evaluation technique for assessing gas output from coal seams during commingling production within a coalbed methane well: a case study from the Qinshui Basin显示文摘Gas drainage is carried out based on output from each coal bed throughout commingling production of coalbed methane(CBM).A reasonable drainage process should therefore initially guarantee main coal bed production and then enhance gas output from other beds.Permanent damage can result if this is not the case,especially with regard to fracture development in the main gas-producing coal bed and can greatly reduce single well output.Current theoretical models and measuring devices are inapplicable to commingled CBM drainage,however,and so large errors in predictive models cannot always be avoided.The most effective currently available method involves directly measuring gas output from each coal bed as well as determining the dominant gas-producing unit.A dynamic evaluation technique for gas output from each coal bed during commingling CBM production is therefore proposed in this study.This technique comprises a downhole measurement system combined with a theoretical calculation model.Gas output parameters(i.e.,gas-phase flow rate,temperature,pressure)are measured in this approach via a downhole measurement system;substituting these parameters into a deduced theoretical calculation model then means that gas output from each seam can be calculated to determine the main gas-producing unit.Trends in gas output from a single well or each seam can therefore be predicted.The laboratory and field test results presented here demonstrate that calculation errors in CBM outputs can be controlled within a margin of 15%and therefore conform with field use requirements. | Chuan Wu Chengxiang Yuan Guojun Wen Lei Han Haojie Liu | 2020 | International Journal of Coal Science & Technology2020，7，1： | 3 |
| 18 | Optimal Waist Circumference Cut-off values for Identifying Metabolic Risk Factors in Middle-aged and Elderly Subjects in Shandong Province of China显示文摘Objective To study the optimal waist circumference(WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China. Methods A total of 2 873 men and 5 559 women were included in this cross-sectional study. Metabolic syndrome(MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared. Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men. Conclusion The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China. | HOU Xin Guo WANG Chuan MA Ze Qiang YANG Wei Fang WANG Ji Xiang LI Cheng Qiao WANG Yu Lian LIU Shu Min Hu Xiu Ping ZHANG Xiu Ping JIANG Mei WANG Wei Qing NING Guang ZHENG Hui Zhen MA Ai Xia SUN Yu SONG Jun LIN Peng LIANG Kai LIU Fu Qiang LI Wen Juan XIAO Juan GONG Lei WANG Mei Jian LIU Ji Dong YAN Fei YANG Jun Peng WANG Ling Shu TIAN Meng ZHAO Ru Xing JIANG Ling CHEN Li | 2014 | Biomedical and Environmental Sciences2014，27，5： | 3 |
| 19 | Distinguishability analysis of controller parameters with applications to DFIG based wind turbine显示文摘The power system controllers normally have more than one parameter.The distinguishability analysis of the controller parameters is to identify whether the optimal set of the parameters of the controllers is unique.It is difficult to obtain the analytic relationship between the objective of the optimization and the controller parameters,which means that the analytical method is not suitable for the distinguishability analysis.Therefore,a trajectory sensitivity based numerical method for the distinguishability analysis of the controller parameters is proposed in this paper.The relationship between the distinguishability and the sensitivities of the parameters is built.The magnitudes of the sensitivities are used to identify the key parameters,while the phase angles of the sensitivities are used to analyze the distinguishability of the key parameters.The distinguishability of the controller parameters of wind turbine with DFIG is studied using the proposed method,and dynamic simulations are performed to verify the results of the distinguishability analysis. | QIN Chuan JU Ping WU Feng LIU Lei | 2013 | Science China(Technological Sciences)2013，56，10： | 3 |
| 20 | Noncontrast-enhanced MRI-based Noninvasive Score for Portal Hypertension(CHESS1802):An International Multicenter Study显示文摘Background and Aims:This study aimed to determine the performance of the non-invasive score using noncontrastenhanced MRI(CHESS-DIS score)for detecting portal hy-pertension in cirrhosis.Methods:In this international multicenter,diagnostic study(ClinicalTrials.gov,NCT03766880),patients with cirrhosis who had hepatic venous pressure gradient(HVPG)measurement and noncontrast-enhanced MRI were prospectively recruited from four university hospitals in China(n=4)and Turkey(n=1)between December 2018 and April 2019.A cohort of patients was retrospectively recruited from a university hospital in Italy between March 2015 and November 2017.After segmentation of the liver on fat-suppressed T1-weighted MRI maps,CHESS-DIS score was calculated automatically by an in-house developed code based on the quantification of liver surface nodularity.Results:A total of 149 patients were included,of which 124 were from four Chinese hospitals(training cohort)and 25 were from two international hospitals(validation cohort).A positive correlation between CHESS-DIS score and HVPG was found with the correlation coefficients of 0.36(p<0.0001)and 0.55(p<0.01)for the training and validation cohorts,respectively.The area under the receiver operating characteristic curve of CHESS-DIS score in detection of clinically significant portal hypertension(CSPH)was 0.81 and 0.9 in the training and validation cohorts,respectively.The intra-class correlation coefficients for assessing the inter-and intra-observer agreement were 0.846 and 0.841,respectively.Conclusions:A non-invasive score using noncontrast-enhanced MRI was developed and proved to be significantly correlated with invasive HVPG.Besides,this score could be used to detect CSPH in patients with cirrhosis. | Yanna Liu Tianyu Tang NecatiÖrmeci Yifei Huang Jitao Wang Xiaoguo Li Zhiwei Li Weimin An Dengxiang Liu Chunqing Zhang Changchun Liu Jinqiang Liu Chuan Liu Guangchuan Wang Cristina Mosconi Alberta Cappelli Antonio Bruno Seray Akçalar EmrecanÇelebioğlu EvrenÜstüner Sadık Bilgiç Zeynep Ellik ÖzgünÖmer Asiller Lei Li Haijun Zhang Ning Kang Dan Xu Ruiling He Yan Wang Yang Bu Ye Gu Shenghong Ju Rita Golfieri Xiaolong Qi | 2021 | Journal of Clinical and Translational Hepatology2021，9，6： | 3 |
