1Active tectonic blocks and strong earthquakes in the continent of China显示文摘The primary pattern of the late Cenozoic to the present tectonic deformation of China is characterized by relative movements and interactions of tectonic blocks. Active tectonic blocks are geological units that have been separated from each other by active tectonic zones. Boundaries between blocks are the highest gradient of differential movement. Most of tectonic activity occurs on boundaries of the blocks. Earthquakes are results of abrupt releases of accumulated strain energy that reaches the threshold of strength of the earth's crust. Boundaries of tectonic blocks are the locations of most discontinuous deformation and highest gradient of stress accumulation, thus are the most likely places for strain energy accumulation and releases, and in turn, devastating earthquakes. Almost all earthquakes of magnitude greater than 8 and 80%-90% of earthquakes of magnitude over 7 occur along boundaries of active tectonic blocks. This fact indicates that differential movements and interactions of active tectonic blocks are the primary mechanism for the occurrences of devastating earthquakes.ZHANG Peizhen (张培震) DENG Qidong (邓起东) ZHANG Guomin (张国民) MA Jin (马 瑾) GAN Weijun (甘卫军) MIN Wei (闵 伟) MAO Fengying (毛凤英) WANG Qi (王 琪) 2003Science China Earth Sciences2003,46,z2:239

4Nitrogen Balance and Loss in a Greenhouse Vegetable System in Southeastern China显示文摘High rates of fertilizer nitrogen (N) are applied in greenhouse vegetable fields in southeastern China to maximize production;however,the N budgets of such intensive vegetable production remain to be explored.The goal of this study was to determine the annual N balance and loss in a greenhouse vegetable system of annual rotation of tomato,cucumber,and celery at five N (urea) application rates (0,348,522,696,and 870 kg N ha-1 year-1).Total N input to the 0-50 cm soil layer ranged from 531 to 1 053 kg ha-1,and N fertilizer was the main N source,accounting for 66%-83% of the total annual N input.In comparison,irrigation water,wet deposition,and seeds in total accounted for less than 1% of the total N input.The fertilizer N use efficiency was only 18% under the conventional application rate of 870 kg N ha-1 and decreased as the application rate increased from 522 to 870 kg N ha-1.Apparent N losses were 196-201 kg N ha-1,of which 71%-86% was lost by leaching at the application rates of 522-870 kg N ha-1.Thus,leaching was the primary N loss pathway at high N application rates and the amount of N leached was proportional to the N applied during the cucumber season.Moreover,dissolved organic N accounted for 10% of the leached N,whereas NH3 volatilization only contributed 0.1%-0.6% of the apparent N losses under the five N application rates in this greenhouse vegetable system.MIN Ju ZHAO Xu SHI Wei-Ming XING Guang-Xi ZHU Zhao-Liang 2011Pedosphere2011,21,4:91
5Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears.Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG 2021Science China(Information Sciences)2021,64,1:122
6Endoscopic variceal ligation compared with endoscopic injection sclerotherapy for treatment of esophageal variceal hemorrhage:A meta-analysis显示文摘AIM:To compare the effect of endoscopic variceal ligation(EVL)with that of endoscopic injection sclerotherapy(EIS)in the treatment of patients withesophageal variceal bleeding.METHODS:We performed a systematic literature search of multiple online electronic databases.Metaanalysis was conducted to evaluate risk ratio(RR)and95%confidence interval(CI)of combined studies for the treatment of patients with esophageal variceal bleeding between EVL and EIS.RESULTS:Fourteen studies comprising 1236 patients were included in the meta-analysis.The rebleeding rate in actively bleeding varices patients in the EVL group was significantly lower than that in the EIS group(RR=0.68,95%CI:0.57-0.81).The variceal eradication rate in actively bleeding varices patients in the EVL group was significantly higher than that in the EIS group(RR=1.06,95%CI:1.01-1.12).There was no significant difference about mortality rate between the EVL group and EIS group(RR=0.95,95%CI:0.77-1.17).The rate of complications in actively bleeding varices patients in the EVL group was significantly lower than that in the EIS group(RR=0.28,95%CI:0.13-0.58).CONCLUSION:Our meta-analysis has found that EVL is better than EIS in terms of the lower rates of rebleeding,complications,and the higher rate of variceal eradication.Therefore,EVL is the first choice for esophageal variceal bleeding.Cong Dai Wei-Xin Liu Min Jiang Ming-Jun Sun 2015World Journal of Gastroenterology2015,21,8:89
7Fecal microbiota transplantation for severe enterocolonic fistulizing Crohn's disease显示文摘The concept of fecal microbiota transplantation(FMT)has been used in traditional Chinese medicine at least since the 4thcentury.Evidence from recent human studies strongly supports the link between intestinal bacteria and inflammatory bowel disease.We proposed that standardized FMT might be a promising rescue therapy for refractory inflammatory bowel disease.However,there were no reports of FMT used in patients with severe Crohn’s disease(CD).Here,we report the successful treatment of standardized FMT as a rescue therapy for a case of refractory CD complicated with fistula,residual Barium sulfate and formation of intraperitoneal large inflammatory mass.As far as we know,this is the first case of severe CD treated using FMT through mid-gut.Fa-Ming Zhang Hong-Gang Wang Min Wang Bo-Ta Cui Zhi-Ning Fan Guo-Zhong Ji 2013World Journal of Gastroenterology2013,19,41:78
8Expression of heat shock proteins (HSP27, HSP60, HSP70, HSP90, GRP78, GRP94) in hepatitis B virus-related hepatocellular carcinomas and dysplastic nodules显示文摘AIM: Expression of heat shock proteins (HSPs) is frequently up-regulated in hepatocellular carcinoma (HCC), which evolves from dysplastic nodule (DN) and early HCC to advanced HCC. However, little is known about the differential expression of HSPs in multistep hepatocarcinogenesis. It was the purpose of this study to monitor the expression of HSPs in multistep hepatocarcinogenesis and to evaluate their prognostic significance in hepatitis B virus (HBV)related HCC.METHODS: Thirty-eight HCC and 19 DN samples were obtained from 52 hepatitis B surface antigen-positive Korean patients. Immunohistochemical and dot immunoblot analyses of HSP27, HSP60, HSP70, HSP90, glucoseregulated protein (GRP)78, and GRP94 were performed and their expression at different stages of HCC development was statistically analyzed.RESULTS: Expression of HSP27, HSP70, HSP90, GRP78, and GRP94 increased along with the stepwise progression of hepatocarcinogenesis. Strong correlation was found only in GRP78 (Spearman's r= 0.802). There was a positive correlation between the expressions of GRP78, GRP94, HSP90, or HSP70 and prognostic factors of HCC. Specifically, the expression of GRP78, GRP94, or HSP90 was associated significantly with vascular invasion and intrahepatic metastasis.CONCLUSION: The expressions of HSPs are commonly up-regulated in HBV-related HCCs and GRP78 might play an important role in the stepwise progression of HBVrelated hepatocarcinogenesis. GRP78, GRP94, and HSP90 may be important prognostic markers of HBV-related HCC, strongly suggesting vascular invasion and intrahepatic metastasis.Seung Oe Lim Sung Gyoo Park Jun-Hi Yoo Young Min Park Hie-Joon Kim Kee-Taek Jang Jae Won Cho Byung Chul Yoo Gu-Hung Jung Cheol Keun Park 2005World Journal of Gastroenterology2005,11,14:62
9GPS-constrained inversion of present-day slip rates along major faults of the Sichuan-Yunnan region, China显示文摘A linked-fault-element model is employed to invert for contemporary slip rates along major active faults in the Sichuan-Yunnan region (96°-108°E, 21°-35°N) using the least squares method. The model is based on known fault geometry, and constrained by a GPS-derived horizontal velocity field. Our results support a model attributing the eastward extrusion of the Tibetan Plateau driven mainly by the north-northeastward indentation of the Indian plate into Tibet and the gravitational collapse of the plateau. Resisted by a relatively stable south China block, materials of the Sichuan-Yunnan region rotate clockwise around the eastern Himalayan tectonic syntaxis. During the process the Garzê-Yushu, Xianshuihe, Anninghe, Zemuhe, Daliangshan, and Xiaojiang faults, the southwest extension of the Xiaojiang fault, and the Daluo-Jinghong and Mae Chan faults constitute the northeast and east boundaries of the eastward extrusion, with their left slip rates being 0.3-14.7, 8.9-17.1, 5.1 ± 2.5, 2.8 ± 2.3, 7.1 ± 2.1, 9.4 ± 1.2, 10.1 ± 2.0, 7.3 ± 2.6, and 4.9 ± 3.0 mm/a respectively. The southwestern boundary consists of a widely distributed dextral transpressional zone other than a single fault. Right slip rates of 4.2 ± 1.3, 4.3 ± 1.1, and 8.5 ± 1.7 mm/a are detected across the Nanhua-Chuxiong-Jianshui, Wuliangshan, and Longling-Lancang faults. Crustal deformation across the Longmenshan fault is weak, with short-ening rates of 1.4 ± 1.0 and 1.6 ± 1.3 mm/a across the Baoxing-Beichuan and Beichuan-Qingchuan segments. Northwest of the Longmenshan fault lies an active deformation zone (the Longriba fault) with 5.1±1.2 mm/a right slip across. Relatively large slip rates are detected across a few faults within the Sichuan-Yunnan block: 4.4±1.3 mm/a left slip and 2.7±1.1 mm/a shortening across the Litang fault, and 2.7±2.3 mm/a right-lateral shearing and 6.7±2.3 mm/a shortening across the Yunongxi fault and its surrounding regions. In conclusion, we find that the Sichuan-Yunnan region is divided into more than a dozen active micro-blocks by a large number of faults with relatively slow slip rates. The eastward extrusion of the Tibetan Plateau is absorbed and adjusted in the region mainly by these faults, other than a small number of large strike-slip faults with fast slip rates.WANG YanZhao WANG EnNing SHEN ZhengKang WANG Min GAN WeiJun QIAO XueJun MENG GuoJie LI TieMing TAO Wei YANG YongLin CHENG Jia LI Peng 2008Science China Earth Sciences2008,51,9:65

11Precise orbit determination of Beidou Satellites with precise positioning显示文摘Chinese Beidou satellite navigation system constellation currently consists of eight Beidou satellites and can provide preliminary service of navigation and positioning in the Asia-Pacific Region.Based on the self-developed software Position And Navigation Data Analysis(PANDA) and Beidou Experimental Tracking Stations (BETS),which are built by Wuhan University,the study of Beidou precise orbit determination,static precise point positioning (PPP),and high precision relative positioning,and differential positioning are carried out comprehensively.Results show that the radial precision of the Beidou satellite orbit determination is better than 10 centimeters.The RMS of static PPP can reach several centimeters to even millimeters for baseline relative positioning.The precision of kinematic pseudo-range differential positioning and RTK mode positioning are 2-4 m and 5-10 cm respectively,which are close to the level of GPS precise positioning.Research in this paper verifies that,with support of ground reference station network,Beidou satellite navigation system can provide precise positioning from several decimeters to meters in the wide area and several centimeters in the regional area.These promising results would be helpful for the implementation and applications of Beidou satellite navigation system.SHI Chuang ZHAO QiLe LI Min TANG WeiMing HU ZhiGang LOU YiDong ZHANG HongPing NIU XiaoJi LIU JingNan 2012Science China Earth Sciences2012,55,7:61

15A nationwide survey of psychological distress among Chinese people in the COVID-19 epidemic:implications and policy recommendations显示文摘The Coronavirus Disease 2019(COVID-19)epidemic emerged in Wuhan,China,spread nationwide and then onto half a dozen other countries between December 2019 and early 2020.The implementation of unprecedented strict quarantine measures in China has kept a large number of people in isolation and affected many aspects of people's lives.It has also triggered a wide variety of psychological problems,such as panic disorder,anxiety and depression.This study is the first nationwide largescale survey of psychological distress in the general population of China during the COVID-19 epidemic.Jianyin Qiu Bin Shen Min Zhao Zhen Wang Bin Xie Yifeng Xu 2020General Psychiatry2020,33,2:69
16Optical vortices 30 years on:OAM manipulation from topological charge to multiple singularities显示文摘Thirty years ago,Coullet et al.proposed that a special optical field exists in laser cavities bearing some analogy with the superfluid vortex.Since then,optical vortices have been widely studied,inspired by the hydrodynamics sharing similar mathematics.Akin to a fluid vortex with a central flow singularity,an optical vortex beam has a phase singularity with a certain topological charge,giving rise to a hollow intensity distribution.Such a beam with helical phase fronts and orbital angular momentum reveals a subtle connection between macroscopic physical optics and microscopic quantum optics.These amazing properties provide a new understanding of a wide range of optical and physical phenomena,including twisting photons,spin–orbital interactions,Bose-Einstein condensates,etc.,while the associated technologies for manipulating optical vortices have become increasingly tunable and flexible.Hitherto,owing to these salient properties and optical manipulation technologies,tunable vortex beams have engendered tremendous advanced applications such as optical tweezers,high-order quantum entanglement,and nonlinear optics.This article reviews the recent progress in tunable vortex technologies along with their advanced applications.Yijie Shen Xuejiao Wang Zhenwei Xie Changjun Min Xing Fu Qiang Liu Mali Gong Xiaocong Yuan 2019Light(Science & Applications)2019,8,1:77
17Animal experiment and clinical study of effect of gamma-interferon on hepatic fibrosis显示文摘AIM To evaluate the antifibrotic effect ofdifferent doses of recombinant human Gamma-Interferon (IFN-γ) intwo rat models of hepaticfibrosis, and to observe its effect on moderatechronic hepatitis B virus fibrosis.METNODS Hepatic fibrosis was successfullyinduced in 150 and 196 rats by subcutaneousinjection of carbon tetrachloride (CCl4) andintraperitoneal injection of dimethylnitrosamine(DMN), respectively. Each of the two modeldose IFN-γ group (15 MU/kg per day, i.m. for 8group (1.67 MU/kg daily, i.m. for 8 weeks).Another group of 10 rats without any treatmentwas used as normal controls. At the end of theexperiment, semi-quantitative histopathologicalscores of inflammation and fibrosis, liver (αsmooth muscle actin (α-SMA) expression level,liver hydroxyl proline content and serumhyaluronic acid levels were compared. And 47medium chronic hepatitis B viral fibrosispatients were studied. They were given IFN-γtreatment, 100MU/day i.m. for the first threemonths and 100MU qod i.m. for the next sixmonths. Semi-quantitative pathological scoresof inflammation and fibrosis and serum hepaticfibrosis indices were compared within the 9months.RESULTS In animal experiment, thepathological fibrosis scores and liver hydroxylproline content were found to be significantlylower in rats treated with different doses of IFN-γ as compared with rats in fibrotic model groupinduced by either CCI4 or DMN, in a dose-dependent manner. For CCI4-induced model,pathological fibrosis scores in high, medium andIow doses IFN-γ groups were 5.10 ± 2.88, 7.70 ±3.53 and 8.00 ± 3.30, respectively, but the scorewas 14.60 ± 7.82 in fibrotic model group.Hydroxyl proline contents were 2.83 ± 1.18, 3.59± 1.22 and 4.80 ± 1.62, in the three IFN-γgroups, and 10.01 ± 3.23 in fibrotic model group.The difference was statistically significant(P<0.01). Similar results were found in DMN-induced model. Pathological fibrosis scoreswere 6.30±0.48, 8.10 ±2.72 and 8.30 ±2.58, inhigh, medium and Iow doses IFN-γ groups, and12.60 ± 3.57 in fibrotic model group. Hydroxylproline contents were 2.72 ± 0.58, 3.14 ± 0.71and 3.62 ± 1.02, in the three IFN-γ groups, and12.79 ± 1.54 in fibrotic model group. Thedifference was statistically significant(P<0.01). Serum hepatic fibrosis indicesdecreased significantly in the 47 patients afterIFN-γ treatment (HA: 433.38 ± 373.00 vs 281.57± 220.48; LN: 161.22± 41.02 vs 146.35 ± 44.67;PCⅢ: 192.59 ± 89.95 vs 156.98 ± 49.22; C-Ⅳ:156.30 ± 44.01 vs 139.14 ± 34.47) and thedifferences between the four indices weresignificant (P<0.05).

18Specific molecular markers in hepatocellular carcinoma显示文摘BACKGROUND: The carcinogenesis of hepatocellular carcinoma (HCC) is a multi-factorial, multistep and complex process. Its prognosis is poor, and early diagnosis and monitoring metastasis of HCC is of the utmost importance. Circulating diagnostic and prognostic biomarkers could be used in proper postoperative treatment of patients at an early stage of HCC development. This review summarizes recent studies of the specific biomarkers in diagnosis and monitoring metastasis or postoperative recurrence of HCC. DATA SOURCES: An English-language literature search was conducted using MEDLINE (June 1998 to September 2006) on researches of some valuable specific biomarkers in diagnosis and monitoring metastasis or postoperative recurrence of HCC. RESULTS: Hepatoma tissues can synthesize various tumor-related proteins, polypeptides, and isoenzymes, such as alpha-fetoprotein (AFP), hepatoma-specific gamma-glutamyl transpeptidase (HS-GGT), etc, and then secrete into blood. The valuable early diagnostic and prognostic biomarkers could predict the development and metastases of HCC. Recent researches have confirmed that circulating hepatoma-specific AFP subfraction, transforming growth factor (TGF)-β1, HS-GGT, and free insulin-like growth factor (IGF)-Ⅱ may be more specific markers than total AFP level for early diagnosis for HCC. The circulating genetic markers such as AFP-mRNA, TGF-β1-mRNA, IGF-Ⅱ-mRNA, etc from peripheral blood mononuclear cells of HCC patients have been most extensively used in monitoring distal metastasis or postoperative recurrence of HCC. CONCLUSIONS: Hepatoma tissues synthesize and secrete valuable molecular markers into blood. The analyses of circulating hepatoma-specific biomarkers are usefulto early diagnosis of HCC or monitoring metastasis or postoperative recurrence of HCC.Yao, Deng-Fu Dong, Zhi-Zhen Yao, Min 2007Hepatobiliary & Pancreatic Diseases International2007,6,3:55
19The oldest basement rock in the Yangtze Craton revealed by zircon U-Pb age and Hf isotope composition显示文摘Here we report an integrated study of zircon U-Pb age and Hf isotope composition for a gneiss sample from the Kongling terrain in the Yangtze Craton. CL imaging reveals that most zircons are magmatic, and a few of them have thin metamorphic rims. The magmatic zircons gave a weighted mean U-Pb age of 3218±13 Ma, indicating the gneiss is the oldest basement rock in the Yangtze Craton found to date. They have εHf(t) value of -2.33±0.51,and two-stage Hf model age of 3679±49 Ma,indicating that the gneiss was derived from partial melting of >3.6 Ga crustal rock. The metamorphic rims yielded an age of 2732±16 Ma, implying that the metamorphic event occurred in the Neoarchean era, which may be also a major tectono-thermal event in the Yangtze Craton.JIAO WenFang WU YuanBao YANG SaiHong PENG Min WANG Jing 2009Science China Earth Sciences2009,52,9:57
20Health risk assessment of heavy metals in soils and vegetables from wastewater irrigated area,Beijing-Tianjin city cluster,China显示文摘The possible health risks of heavy metals contamination to local population through food chain were evaluated in Beijing and Tianjin city cluster,China,where have a long history of sewage irrigation.The transfer factors(TF) for heavy metals from soil to vegetables for six elements including Cu,Zn,Pb,Cr,As and Cd were calculated and the pollution load indexes(PLI) were also assessed.Results indicate that only Cd exceeded the maximum acceptable limit in these sites.So far,the heavy metal concentrations in soils and vegetables were all below the permissible limits set by the Ministry of Environmental Protection of China and World Health Organization.The transfer factors of six heavy metals showed the trend as Cd > Zn > Cu > Pb > As > Cr,which were dependent on the vegetable species.The estimated dietary intakes of Cu,Zn,Pb,Cr,As and Cd were far below the tolerable limits and the target hazard quotient(THQ) values were less than 1,which suggested that the health risks of heavy metals exposure through consuming vegetables were generally assumed to be safe.Yanchun Wang Min Qiao Yunxia Liu Yongguan Zhu 2012Journal of Environmental Sciences2012,24,4:52
