| 3 | Destruction of the North China Craton显示文摘A National Science Foundation of China(NSFC) major research project,Destruction of the North China Craton(NCC),has been carried out in the past few years by Chinese scientists through an in-depth and systematic observations,experiments and theoretical analyses,with an emphasis on the spatio-temporal distribution of the NCC destruction,the structure of deep earth and shallow geological records of the craton evolution,the mechanism and dynamics of the craton destruction.From this work the following conclusions can be drawn:(1) Significant spatial heterogeneity exists in the NCC lithospheric thickness and crustal structure,which constrains the scope of the NCC destruction.(2) The nature of the Paleozoic,Mesozoic and Cenozoic sub-continental lithospheric mantle(CLM) underneath the NCC is characterized in detail.In terms of water content,the late Mesozoic CLM was rich in water,but Cenozoic CLM was highly water deficient.(3) The correlation between magmatism and surface geological response confirms that the geological and tectonic evolution is governed by cratonic destruction processes.(4) Pacific subduction is the main dynamic factor that triggered the destruction of the NCC,which highlights the role of cratonic destruction in plate tectonics. | ZHU RiXiang XU YiGang ZHU Guang ZHANG HongFu XIA QunKe ZHENG TianYu | 2012 | Science China Earth Sciences2012，55，10： | 119 |
| 4 | Th e role of ferroptosis in ionizing radiation-induced cell death and tumor suppression显示文摘Ferroptosis,a form of regulated cell death caused by lipid peroxidation,was recently identified as a natural tumor suppression mechanism.Here,we show that ionizing radiation(IR)induces ferroptosis in cancer cells.Mechanistically,IR induces not only reactive oxygen species(ROS)but also the expression of ACSL4,a lipid metabolism enzyme required for ferroptosis,resulting in elevated lipid peroxidation and ferroptosis.ACSL4 ablation largely abolishes IR-induced ferroptosis and promotes radioresistance.IR also induces the expression of ferroptosis inhibitors,including SLC7A11 and GPX4;as an adaptive response.IR-or KEAP1 deficiencyinduced SLC7A11 expression promotes radioresistance through inhibiting ferroptosis.Inactivating SLC7A11 or GPX4 with ferroptosis inducers(FINs)sensitizes radioresistant cancer cells and xenograft tumors to IR.Furthermore,radiotherapy induces ferroptosis in cancer patients,and increased ferroptosis correlates with better response and longer survival to radiotherapy in cancer patients.Our study reveals a previously unrecognized link between IR and ferroptosis and indicates that further exploration of the combination of radiotherapy and FINs in cancer treatment is warranted. | Guang Lei Yilei Zhang Pranavi Koppula Xiaoguang Liu Jie Zhang Steven HLin Jaffer AAjani Qin Xiao Zhongxing Liao Hui Wang Boyi Gan | 2020 | Cell Research2020，30，2： | 88 |
| 5 | Discovery of the Early Paleozoic post-collisional granites in northern margin ofthe Erguna massif and its geological significance显示文摘The Luoguhe intrusion, located in MoheCounty, Heilongjiang Province, is mainly composed of mon-zogranite, quartz diorite and granodiorite, with minor dio-rite, tonalite, quartz monzodiorite, quartz monzonite, syeno-granite and alkali-feldspar granite. The intrusion can bedivided into two lithological units, i.e. quartz diorite andmonzogranite units, with affinities to high-K calc-alkalineseries. The quartz diorite unit (SiO2: 54.79%―58.30%Na2O/CaO: 0.79―1.53 and Shand index: 0.77―0.82) belongsto metaluminous rocks. And the monzogranite unit (SiO2:65.29%―66.45%, Na2O/CaO: 1.73―3.43 and Shand index<1.05) can be considered as weakly peraluminous rocks. Theintrusion is characterized by high REE abundance (∑REE =180.2―344.3 μg/g), medium-strong negative Eu anomalies(δ Eu = 0.33―0.82), weak REE fractionation [(La/Yb)N =4.12―10.45], enrichments in Rb, Th, U, K, La, Ce, Nd, HfZr and Sm, but strong depletions of Ba, Nb, Ta, Sr, P and TiThese characteristics of major, REE and trace elements in-dicate that the intrusion was formed in a transitional tectonicsetting from compressional to extensional regime, which canbe classified as post-collisional granitoids. SHRIMP U-Pbzircon analyses yield ages of 517±9 and 504±8 Ma for thequartz diorite and monzogranite units, respectively. The dis-covery of Early Paleozoic post-collisional granites in thenorthern margin of the Erguna massif indicates that thenorthern branch of Paleo-Asian Ocean between Siberianplate and Erguna massif was closed in the Early Paleozoicand the Salair orogeny ended ca. 500 Ma ago. | WU Guang SUN Fengyue ZHAO Caisheng LI Zhitong ZHAO Ailin PANG Qingbang LI Guangyuan | 2005 | Chinese Science Bulletin2005，50，23： | 69 |
| 6 | Lake eutrophication and its ecosystem response显示文摘China is a country with many lakes,about one-third of which are freshwater mainly distributed in the middle and lower reaches of the Yangtze River.Currently most of the lakes are mesotrophic or eutrophic.Lake eutrophication has become one of the major ecological and environmental problems faced by lakes in China and can lead to a series of abnormal ecosystem responses,including extinction of submerged plants,frequent occurrence of cyanobacterial blooms,increased microbial biomass and productivity,decreased biodiversity,accelerated cycles,and a change in the efficient use of nutrients.With development of eutrophication,the whole lake ecosystem suffers decreased biodiversity,simplification of biotic community structure,instability of the ecosystem,and ultimately the clear-water,macrophyte-dominated ecosystem gradually shifts to a turbid-water,algae-dominated ecosystem.This ecosystem succession mechanism is speculated to be caused by different nutrient utilization efficiencies of macrophytes and phytoplankton.The ultimate ecosystem succession trend of seriously eutrophic lakes is that a phytoplankton-dominated autotrophic lake shifts to a heterotrophic lake dominated by micro-organisms,protozoans. | QIN BoQiang GAO Guang ZHU GuangWei ZHANG YunLin SONG YuZhi TANG XiangMing XU Hai DENG JianMing | 2013 | Chinese Science Bulletin2013，58，9： | 63 |
| 7 | Methodologic research on TIMP-1,TIMP-2 detection as a new diagnostic index for hepatic fibrosis and its significance显示文摘AIM: To set up a new method to detect tissue inhibitors ofmetalloproteinase1 and -2(TIMP-1 and TIMP-2) in sero ofpatients with hepatic cirrhosis, and to investigate theexpression and location of TIMP-1 and TIMP-2 in liver tissueof patients with hepatic cirrhosis, and the correlationbetween TIMPs in liver and those in sera so as to discusswhether TIMPs can be used ss a diagnosis index of hepaticfibrosisMETHODS: The monoclonal antibodies (McAbs) of TIMP-1and TIMP-2 were used to sensitize erythrocytes, and solid-phase absorption to sensitized erythrocytes (SPASE) wasused to detect TIMP-1 and TIMP-2 in the sera of patients withhepatic cirrhosis. Meanwhile, with the method of in situhybridization and immunohistochemistry, we studied themRNA expression and antigen location of TIMP-1 and TIMP-2in the livers of 40 hepatic cirrhosis patients with pathologicdiagnosis.RESULTS: With SPASE, they were 16.4 % higher in theacute hepatitis group, 33.3 % higher in the chronic hepatitisgroup, and the positive rates were 73.6 % and 61. 2 %respectively in sero of hepatic cirrhosis patients, which wereremarkably higher than those in chronic hepatitis and acutehepatitis group ( P < 0. 001 ). In 40 samples of hepaticcirrhosis tissues, all of them showed positive expression ofTIMP-1 and TIMP-2 mRNA detected withimmunohistochemistry or in situ hybridization (positive ratewas 100 % ). Expression of TIMPs in different degrees couldbe found in liver tissue with cirrhosis. TIMPs were located incytoplasm of liver cells of patients with hepatic cirrhosis.There was a significant correlation between serum TIMPslevel and liver TIMPs level.CONCLUSION: SPASE is a useful method to detect the TIMP-1 and TIMP-2 in sera of patients with hepatic cirrhosis, andTIMP-1 and TIMP-2 can be considered as a useful diagnosticindex of hepatic fibrosis, especially TIMP-1. | Oing-He Nie Yong-Oian Cheng Yu-Mei Xie Yong-Xing Zhou Bai-Xian Guang Yi-Zhan Cao,The Centre of Diagnosis and Treatment for Infectious Disease of Chinese PLA,Tangdu Hospital,Fourth Military Medical University,Xi’an 710038,Shanxi Province,China | 2002 | World Journal of Gastroenterology2002，8，2： | 51 |
| 8 | Berberine reverses free-fatty-acid-induced insulin resistance in 3T3-L1 adipocytes through targeting IKKβ显示文摘AIM: To investigate the effects and molecular mechanisms of berberine on improving insulin resistance induced by free fatty acids (FFAs) in 3T3-L1 adipocytes. METHODS: The model of insulin resistance in 3T3-L1 adipocytes was established by adding palmic acid (0.5 mmol/L) to the culture medium. Berberine treatment was performed at the same time. Glucose uptake rate was determined by the 2-deoxy-[3H]-D-glucose method. The levels of IkB kinase beta (IKKβ) Ser181 phosphorylation, insulin receptor substrate-1(IRS-1) Ser307 phosphorylation, expression of IKKβ, IRS-1, nuclear transcription factor kappaB p65 (NF-κB p65), phosphatidylinositol-3-kinase p85 (PI-3K p85) and glucose transporter 4 (GLUT4) proteins were detected by Western blotting. The distribution of NF-κB p65 proteins inside the adipocytes was observed through confocal laser scanning microscopy (CLSM). RESULTS: After the intervention of palmic acid for 24 h, the insulin-stimulated glucose transport in 3T3-L1 adipocytes was inhibited by 67%. Meanwhile, the expression of IRS-1 and PI-3K p85 protein was reduced, while the levels of IKKβ Ser181 and IRS-1 Ser307 phosphorylation, and nuclear translocation of NF-κB p65 protein were increased. However, the above indexes, which indicated the existence of insulin resistance, were reversed by berberine although the expression of GLUT4, IKKβ and total NF-κB p65 protein were not changed during this study. CONCLUSION: Insulin resistance induced by FFAs in 3T3-L1 adipocytes can be improved by berberine. Berberine reversed free-fatty-acid-induced insulin resistance in 3T3-L1 adipocytes through targeting IKKβ. | Ping Yi Fu-Er Lu Li-Jun Xu Guang Chen Hui Dong Kai-Fu Wang | 2008 | World Journal of Gastroenterology2008，14，6： | 50 |

| 10 | A novel advanced oxidation process to degrade organic pollutants in wastewater:Microwave-activated persulfate oxidation显示文摘This article,for the first time,provides a novel advanced oxidation process based on sulfate radical(SO4. -) to degrade organic pollutants in wastewater:microwave(MW)-activated persulfate oxidation(APO)with or without active carbon(AC).Azo dye acid Orange 7(AO7)is used as a model compound to investigate the high reactivity of MW-APO.It is found that AO7(up to 1000 mg/L)is completely decolorized within 5-7 min under an 800 W MW furnace assisted-APO.In the presence of chloride ion(up to 0.50 mol/L),the decolorization is still 100%completed,though delayed for about 1-2 min.Experiments are made to examine the enhancement by AC.It is exciting to find that the 100%decolorization of AO7(500 mg/L)is achieved within 3 min by MW-APO using 1.0 g/L AC as catalyst,while the degradation effciency maintains at 50%by MW energy without persulfate after about 5 min.Besides the destruction of visible light chromophore band of AO7(484 nm),during MW-APO,two bands in the ultraviolet region(228 nm and 310 nm)are rapidly broken down.The removal of COD is about 83%-95%for 500 mg/L AO7.SO4. -is identified with quenching studies using specific alcohols.Both SO4. -and.OH could degrade AO7,but SO 4 .-plays the dominant role.In a word,MW-APO AC is a new catalytic combustion technology for destruction of organic contamination even for high concentration. | YANG Shiying WANG Ping YANG Xin WEI Guang ZHANG Wenyi SHAN Liang | 2009 | Journal of Environmental Sciences2009，21，9： | 41 |
| 11 | Estimation of internal nutrient release in large shallow Lake Taihu, China显示文摘Based on field investigation of wave, sediment suspension and the changes in nutrient concentration of the water column in Lake Taihu, China, we proposed two release models to quantify nutrient release under static and dynamic conditions, respectively. Under static conditions, nutrient release from sediments to the overlying water mainly depends on chemical diffusion induced by concentration gradient, in which the nutrient release is controlled by the temperature, dissolved oxygen concentration in the sediment-water interface, oxidation-reduction potential and the concentration difference between porewater and overlying water. Under dynamic condition (or disturbed condition),both dissolved and particulate nutrients in sediments are released into the water column because of wind-induced sediment suspension. The amount of nutrient release under dynamic conditions is larger than that under the static condition. The release of dissolved nutrients, however, does not increase because the wind induced turbulence made oxidation of metallic elements such as Fe (ferric iron), Mn which are capable of precipitating soluble reactive phosphate (SRP). Under dynamic conditions, therefore, the release of total phosphorus (TP) increases dramatically but the release of SRP is close to those under static conditions. In sediments of Lake Taihu, high Fe content leads to a high ratio of Fe to P contents in sediments (Fe:P ratio). Under dynamic conditions, therefore, nutrient release is controlled by the intensity of disturbance, sediment consolidation and nutrient content in sediments.As for dissolved nutrients, especially SRP, the release is also controlled by the intensity of dynamic re-oxidation, Fe content in sediments and nutrient concentration gradient between porewater and overlying water. Based on these two release modes, the release flux in Lake Taihu has been estimated. In the static condition (i.e. laboratory experimental condition), total release of NH4+-N for whole lake is ca. 10,000 ton/a, and PO43--P is ca. 900 ton/a. In the dynamic condition, nutrient release following sediment suspension was estimated according to three different intensities of wind forcing which were defined as 'calm' (wind speed is less than 2 m/s), 'gentle' (wind speed is greater than 2 m/s and less than 6 m/s) and 'gust' (wind speed is greater than 6 m/s). The release rate in the condition of 'calm' was estimated in terms of the nutrient release in the laboratory experimental static condition; whereas the release rate in conditions of 'gentle' and 'gust' was estimated in terms of measurement during sediment resuspension conducted in flume experiments. With the observation of wind velocity and frequency in 2001, each type of wind forcing took the frequency of 12%, 82% and 6% for 'calm', 'gentle' and 'gust', respectively. The yearly release of nitrogen was 81,000 ton and phosphorus was 21,000 ton, which is about 2-6 folds of annual external loading, respectively. | QIN Boqiang, ZHU Guangwei, ZHANG Lu, LUO Liancong, GAO Guang & GU Binhe Nanjing Institute of Geography & Limnology, Chinese Academy of Sciences, Nanjing 210008, China Everglades Department, South Florida Water Management District, 3301 Gun Club Road, West Palm Beach, FL 33406, USA | 2006 | Science China Earth Sciences2006，49，z1： | 37 |
| 12 | Oceanic plate subduction history in the western Pacific Ocean:Constraint from late Mesozoic evolution of the Tan-Lu Fault Zone显示文摘The NE-to NNE-striking Tan-Lu Fault Zone(TLFZ) is the largest fault zone in East China, and a typical representative for the circum-Pacific tectonics. Its late Mesozoic evolution resulted from subduction of the Paleo-Pacific Plate,and can be used for indication to the subduction history. The TLFZ reactivated at the end of Middle Jurassic since its origination in Middle Triassic. This phase of sinistral motion can only be recognized along the eastern edge of the Dabie-Sulu orogenis,and indicates initiation of the Paleo-Pacific(Izanagi) Plate subduction beneath the East China continent. After the Late Jurassic standstill, the fault zone experienced intense sinistral faulting again at the beginning of Early Cretaceous under N-S compression that resulted from the NNW-ward, low-angle, high-speed subduction of the Izanagi Plate. It turned into normal faulting in the rest of Early Cretaceous, which was simultaneous with the peak destruction of the North China Craton caused by backarc extension that resulted from rollback of the subducting Izanagi Plate. The TLFZ was subjected to sinistral, transpressive displacement again at the end of Early Cretaceous. This shortening event led to termination of the North China Craton destruction. The fault zone suffered local normal faulting in Late Cretaceous due to the far-field, weak backarc extension. The late Mesozoic evolution of the TLFZ show repeated alternation between the transpressive strike-slip motion and normal faulting. Each of the sinistral faulting event took place in a relatively short period whereas every normal faulting event lasted in a longer period, which are related to the subduction way and history of the Paleo-Pacific Plates. | Guang ZHU Cheng LIU Chengchuan GU Shuai ZHANG Yunjian LI Nan SU Shiye XIAO | 2018 | Science China Earth Sciences2018，61，4： | 38 |
| 13 | Anti-tumor activities and apoptosis-regulated mechanisms of bufalin on the orthotopic transplantation tumor model of human hepatocellular carcinoma in nude mice显示文摘AIM: To investigate anti-tumor activities and apoptosis-regulated mechanisms of bufalin in the orthotopic transplantation tumor model of human hepatocellular carcinoma in nude mice.METHODS: BEL-7402 cells of human hepatocellular carcinoma were inoculated to form subcutaneous tumors, and were implanted into the liver to establish orthotopic transplantation tumor models of human hepatocellular carcinoma in nude mice. Seventy-five animals were randomized divided into five groups (n = 15). Bufalin was injected intraperitoneally into three groups at doses of 1.5 mg/kg (BF1), 1 mg/kg (BF2) and 0.5 mg/kg (BF3) for d 15-24, respectively. The NS group was injected an equal volume of saline as above and adriamycin was injected intraperitoneally into the ADM group at a dose of 8.0 mg/kg for d 15. Ten mice in each group were killed at d 25 and the survival time in each group was calculated. We also observed the morphologic alterations in the myocardium, brain, liver, kidney and tumor tissues by pathology and electron microscopy, measured the apoptotic rate by TUNEL staining method, and detected the expression of apoptosis-regulated genes bcl-2 and bax by immunohistochemical staining and RT-PCR in tumor tissues. RESULTS: The tumor volumes in each group of bufalin were reduced significantly (35.21 ± 12.51 vs 170.39 ± 25.29; 49.83 ± 11.46 vs 170.39 ± 25.29; 83.99 ± 24.63 vs 170.39 ± 25.29, P < 0.01, respectively), and the survival times were prolonged in group BF1-2 (31.8 ± 4.2 vs 23.4 ± 2.1 and 29.4 ± 3.4 vs 23.4 ± 2.1, P < 0.05, respectively), and necrosis was mainly in severe or moderate degree in group BF1-2. No morphologicalchanges were detected in the myocardium, brain, liver and kidney tissues. Apoptotic characteristics could be seen in group BF1-2. The positive rates of bcl-2 and bax protein expression of each group by immunohistochemical staining were 10.0%, 10.0%, 20.0%, 10.0% and 20.0%; 90.0%, 80.0%, 80.0%, 40.0% and 30.0%, respectively. Loss of expression of bcl-2 mRNA in each group was to be found and the density of bax mRNA was increased progressively with increase of dose of bufalin by RT-PCR. CONCLUSION: Bufalin has significant anti-tumor activities in the orthotopic transplantation tumor model of human hepatocellular carcinoma in nude mice with no marked toxicity and was able to induce apoptosis of transplanted tumor cells. This apoptosis may be mediated mainly via up-regulating the expression of apoptosis-regulated gene bax, which may be involved in its anti-tumor mechanism of bufalin. | Ke-Qi Han Guang Huang Wei Gu Yong-Hua Su Xue-Qiang Huang Chang-Quan Ling | 2007 | World Journal of Gastroenterology2007，13，24： | 32 |
| 14 | Computed tomography perfusion in evaluating the therapeutic effect of transarterial chemoembolization for hepatocellular carcinoma显示文摘AIM: To prospectively assess the changes in parameters of computed tomography (CT) perfusion pre-and post-transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC) in different treatment response groups, and to correlate the changes with various responses of HCC to TACE. METHODS: Thirty-nine HCC patients underwent CT perfusion examinations pre-(1 d before TACE) and post-treatment (4 wk after TACE). The response evaluation criteria for solid tumors (RECIST) were referred to when treatment responses were distributed. Wilcoxon-signed ranks test was used to compare the differences in CT perfusion parameters pre-and post-TACE for different response groups. RESULTS: Only one case had treatment response to CR and the CT perfusion maps of post-treatment lesion displayed complete absence of signals. In the PR treatment response group, hepatic artery perfusion (HAP), hepatic arterial fracture (HAF) and hepatic blood volume (HBV) of viable tumors post-TACE were reduced compared with pre-TACE (P = 0.001, 0.030 and 0.001, respectively). In the SD group, all CT perfusion parameters were not significantly different pre-and post-TACE. In the PD group, HAP, HAF, portal vein perfusion (PVP) and hepatic blood flow (HBF) of viable tumors post-TACE were significantly increased compared with pre-TACE (P = 0.005, 0.012, 0.035 and 0.005, respectively). CONCLUSION: Changes in CT perfusion parameters of viable tumors are correlated with different responses of HCC to TACE. Therefore, CT perfusion imaging is a feasible technique for monitoring response of HCC to TACE. | Guang Chen Da-Qing Ma Wen He Bao-Feng Zhang Li-Qin Zhao | 2008 | World Journal of Gastroenterology2008，14，37： | 34 |

| 17 | Ferroptosis,radiotherapy,and combination therapeutic strategies显示文摘Ferroptosis,an iron-dependent form of regulated cell death driven by peroxidative damages of polyunsatu-rated-fatty-acid-containing phospholipids in cellular membranes,has recently been revealed to play an important role in radiotherapy-induced cell death and tumor suppression,and to mediate the synergy between radiotherapy and immunotherapy.In this review,we summarize known as well as putative mechanisms underlying the crosstalk between radiotherapy and fer-roptosis,discuss the interactions between ferroptosis and other forms of regulated cell death induced by radiotherapy,and explore combination therapeutic strategies targeting ferroptosis in radiotherapy and immunotherapy.This review will provide important frameworks for future investigations of ferroptosis in cancer therapy. | Guang Lei Chao Mao Yuelong Yan Li Zhuang Boyi Gan | 2021 | Protein & Cell2021，12，11： | 29 |
| 18 | The intracellular mechanism of alpha-fetoprotein promoting the proliferation of NIH 3T3 cells显示文摘AIM The existence and properties of alpha-fetoprotein (AFP) receptor on the surface of NIH 3T3 cells and the effects of AFP on cellular signal transduction pathway were investigated. METHODS The effect of AFP on the proliferation of NIH 3T3 cells was measured by incorporation of 3H-TdR. Receptor-binding assay of 125I-AFP was performed to detect the properties of AFP receptor in NIH 3T3 cells. The influences of AFP on the [cAMP]i and the activities of protein kinase A (PKA) were determined. Western blot was used to detect the change of K-ras P21 protein expression. RESULTS The proliferation of NIH 3T3 cells treated with 0-80 mg/L of AFP was significantly enhanced. The Scatchard analysis indicated that there were two classes of binding sites with KD of 2.722×10-9M (Bmax=12810 sites per cell) and 8.931× 10-SM (Bmax=l19700 sites per cell) respectively. In the presence of AFP (20 mg/L), the content of cAMP and activities of PKA were significantly elevated . The level of K-ras P21 protein was upregulated by AFP at the concentration of 20 mg/L. The monoclonal antibody against AFP could reverse the effects of AFP on the cAMP content, PKA activity and the expression of K-ras p21 gene. CONCLUSION The effect of AFP on the cell proliferation was achieved by binding its receptor to trigger the signal transduction pathway of cAMP-PKA and alter the expression of K- ras p21 gene. | MENG SEN LI, PING FENG LI, FBI YI YANG, SHI PENG HE, Guo GUANG DU, GANG LI1 Department of Biochemistry and Molecular Biology, 2 Department of Biophysics, Health Science Center, Peking University, Beijing 100083, China | 2002 | Cell Research2002，12，2： | 27 |
