1Contribution of the Compass satellite navigation system to global PNT users显示文摘As one of the four global satellite navigation systems,Compass not only enhances satellite visibility and availability for positioning,navigation and timing (PNT) for users in China and the surrounding areas,but also improves PNT precision for global users.The improvements in satellite visibility and the dilution of precision are analyzed under GNSS compatibility and interoperation conditions.The contribution of the Compass satellite navigation system to global users,especially the benefits that users can acquire from the combination of Compass,GPS,GLONASS,and Galileo navigation systems,is analyzed using simulation data.YANG YuanXi LI JinLong XU JunYi TANG Jing GUO HaiRong HE HaiBo 2011Chinese Science Bulletin2011,56,26:90
2Preliminary assessment of the navigation and positioning performance of BeiDou regional navigation satellite system显示文摘BeiDou regional navigation satellite system(BDS)also called BeiDou-2 has been in full operation since December 27,2012.It consists of 14 satellites,including 5 satellites in Geostationary Orbit(GEO),5 satellites in Inclined Geosynchronous Orbit(IGSO),and 4 satellites in Medium Earth Orbit(MEO).In this paper,its basic navigation and positioning performance are evaluated preliminarily by the real data collected in Beijing,including satellite visibility,Position Dilution of Precision(PDOP)value,the precision of code and carrier phase measurements,the accuracy of single point positioning and differential positioning and ambiguity resolution(AR)performance,which are also compared with those of GPS.It is shown that the precision of BDS code and carrier phase measurements are about 33 cm and 2 mm,respectively,which are comparable to those of GPS,and the accuracy of BDS single point positioning has satisfied the design requirement.The real-time kinematic positioning is also feasible by BDS alone in the opening condition,since its fixed rate and reliability of single-epoch dual-frequency AR is comparable to those of GPS.The accuracy of BDS carrier phase differential positioning is better than 1 cm for a very short baseline of 4.2 m and 3 cm for a short baseline of 8.2 km,which is on the same level with that of GPS.For the combined BDS and GPS,the fixed rate and reliability of single-epoch AR and the positioning accuracy are improved significantly.The accuracy of BDS/GPS carrier phase differential positioning is about 35 and 20%better than that of GPS for two short baseline tests in this study.The accuracy of BDS code differential positioning is better than 2.5 m.However it is worse than that of GPS,which may result from large code multipath errors of BDS GEO satellite measurements.YANG YuanXi LI JinLong WANG AiBing XU JunYi HE HaiBo GUO HaiRong SHEN JunFei DAI Xian 2014Science China Earth Sciences2014,57,1:125

5Growth inhibition and apoptosis induction Sulindac on Human gastric cancer cells显示文摘AIM: To evaluate the effects of sulindac in inducing growth inhibition and apoptosis of human gastric cancer cells in comparison with human hepatocellular carcinoma (HCC)cells.METHODS: The human gastric cancer cell lines MKN45 and MKN28 and human hepatocellular carcinoma cell lines HepG2and SMMC7721 were used for the study. Anti-proliferative effect was measured by MTT assay, and apoptosis was determined by Hoechst-33258 staining, electronography and DNA fragmentation. The protein of cyclooxygenase-2 (COX(2) and Bcl-2 were detected by Westem dot blotting.RESULTS: Sulindac could initiate growth inhibition and apoptosis of MKN45, MKN28, HepG2 and SMMC7721 cells in a dose-and time-dependent manner. Growth inhibitory activity and apoptosis were more sensitive in HepG2 cells than in SMMC7721 cells, MKN45 and MKN28 cells. After 24hours incubation with sulindac at 2mmol. L-1 and 4mmol.L-1, the level of COX-2 and Bcl-2 protein were lowered in MKN45, SMMC7721 and HepG2 cells but not in MKN28 cells.CONCLUSION: Sulindac could inhibit the growth of gastric cancer cells and HCC cells effectively in vitro by apoptosis induction, which was associated with regression of COX-2and Bcl-2 expression. The growth inhibition and apoptosis of HCC cells were greater then that of human gastric cancer cells. The different effects of apoptosis in gastric cancer cells may be related to the differentiation of the cells.Yun-Lin Wu~1 Bo Sun~1 Xue-Jun Zhang~2 Sheng-Nian Wang~2 Heng-Yi He~2 Min-Min Qiao~1 Jie Zhong~1 Jia-Yu Xu~1 1 Department of Gastroenterology,Ruijin Hospital,Shanghai Second Medical University,Shanghai 200025,China2 Institude of Biochemistry and Cell Biology,Shanghai Institues for Biological Sciences,Chinese Academy of Sciences.Shanghai 200025,China 2001World Journal of Gastroenterology2001,7,6:64
6On the timing and duration of the destruction of the North China Craton显示文摘The timing and duration of the destruction of the North China Craton, which is pivotal to understanding the destruction mechanism and its geodynamic controlling factors, still remain controversial. On the basis of the principles of magma genesis and evolution, first we outline magmatic expressions that can be related to cratonic destruction, then use magmatic and basin evolution trends to constrain the timescale of the lithospheric thinning in North China. The main conclusions include: (1) the thinning of the lithosphere beneath the North China Craton might have started, at least locally, since late Carboniferous-late Triassic, attained its climax during the late Jurassic-early Cretaceous, and continued till the end of late Cretaceous-early Cenozoic. The destruction of the North China Craton was a relatively slow, rather than a dramatic process. (2) The weakened lithospheric zones along the margins and interiors of the craton played an important role in cratonic destruction, partly accounting for the heterogeneous pattern of cratonic destruction. (3) The tectonic factors that controlled the destruction of the North China Craton may be multiple. The late Carboniferous southward subduction of the Paleo-Asian plate and the late Triassic collision between North China and South China may have re-activated the craton by influencing the thermal and integral structure of the craton. The Pacific subduction underneath the eastern Asian continent played a determinant role in the cratonic destruction, governing the distribution patterns of post-Mesozoic basins and major tectonic configuration, temporal change of magmatism and formation of the North-South gravity lineament.XU YiGang LI HongYan PANG ChongJin HE Bin 2009Chinese Science Bulletin2009,54,19:70

9Systemic immune-inflammation index for predicting prognosis of colorectal cancer显示文摘AIM To investigate the clinical significance of preoperative systemic immune-inflammation index(SII) in patients with colorectal cancer(CRC). METHODS A retrospective analysis of 1383 cases with CRC was performed following radical surgery. SII was calculated with the formula SII =(P × N)/L, where P, N, and L refer to peripheral platelet, neutrophil, and lymphocyte counts, respectively. The clinicopathological features and follow-up data were evaluated to compare SII with other systemic inflammation-based prognostic indices such as the neutrophil-lymphocyte ratio(NLR) and platelet-lymphocyte ratio(PLR) in patients with CRC.RESULTS The optimal cut-off point for SII was defined as 340. The overall survival(OS) and disease-free survival(DFS) were better in patients with low NLR, PLR, and SII(P < 0.05). The SII was an independent predictor of OS and DFS in multivariate analysis. The area under the receiver-operating characteristics(ROC) curve for SII(0.707) was larger than those for NLR(0.602) and PLR(0.566). In contrast to NLR and PLR, SII could effectively discriminate between the TNM subgroups. CONCLUSION SII is a more powerful tool for predicting survival outcome in patients with CRC. It might assist the identification of high-risk patients among patients with the same TNM stage.Jian-Hui Chen Er-Tao Zhai Yu-Jie Yuan Kai-Ming Wu Jian-Bo Xu Jian-Jun Peng Chuang-Qi Chen Yu-Long He Shi-Rong Cai 2017World Journal of Gastroenterology2017,23,34:79
10Synthesis and paste properties of octenyl succinic anhydride modified early Indica rice starch显示文摘Octenyl succinic anhydride (OSA) modified early Indica rice starch was prepared in aqueous slurry systems using response surface methodology. The paste properties of the OSA starch were also investigated. Results indicated that the suitable parameters for the preparation of OSA starch from early Indica rice starch were as follows: reaction period 4 h, reaction tem- perature 33.4 °C, pH of reaction system 8.4, concentration of starch slurry 36.8% (in proportion to water, w/w), amount of OSA 3% (in proportion to starch, w/w). The degree of substitution was 0.0188 and the reaction efficiency was 81.0%. The results of paste properties showed that with increased OSA modification, the starch derivatives had higher paste clarity, decreased retro- gradation and better freeze-thaw stability.SONG Xiao-yan CHEN Qi-he RUAN Hui HE Guo-qing XU Qiong 2006Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2006,7,10:51

14Efficacy and safety of bevacizumab plus chemotherapy in Chinese patients with metastatic colorectal cancer:a randomized phase Ⅲ ARTIST trial显示文摘The efficacy and safety of bevacizumab with modified irinotecan,leucovorin bolus,and 5-fluorouracil intravenous infusion(mIFL) in the first-line treatment of metastatic colorectal cancer(mCRC) has not been well evaluated in randomized clinical trials in Chinese patients.We conducted a phrase Ⅲ trial in which patients with previously untreated mCRC were randomized 2:1 to the mIFL [irinotecan(125 mg/m2),leucovorin(20 mg/m2) bolus,and 5-fluorouracil intravenous infusion(500 mg/m2) weekly for four weeks every six weeks] plus bevacizumab(5 mg/kg every two weeks) group and the mIFL group,respectively.Co-primary objectives were progression-free survival(PFS) and 6-month PFS rate.In total,214 patients were enrolled.Our results showed that addition of bevacizumab to mIFL significantly improved median PFS(4.2 months in the mIFL group vs.8.3 months in the bevacizumab plus mIFL group,P < 0.001),6-month PFS rate(25.0% vs.62.6%,P < 0.001),median overall survival(13.4 months vs.18.7 months,P = 0.014),and response rate(17% vs.35%,P = 0.013).Grades 3 and 4 adverse events included diarrhea(21% in the mIFL group and 26% in the bevacizumab plus mIFL group) and neutropenia(19% in the mIFL group and 33% in the bevacizumab plus mIFL group).No wound-healing complications or congestive heart failure occurred.Our results suggested that bevacizumab plus mIFL is effective and well tolerated as first-line treatment for Chinese patients with mCRC.Clinical benefit and safety profiles were consistent with those observed in pivotal phase Ⅲ trials with mainly Caucasian patients.Zhong-Zhen Guan Jian-Ming Xu Rong-Cheng Luo Feng-Yi Feng Li-Wei Wang Lin Shen Shi-Ying Yu Yi Ba Jun Liang Dong Wang Shu-Kui Qin Jie-Jun Wang Jing He Chuan Qi Rui-Hua Xu 2011Chinese Journal of Cancer2011,30,10:48
15Acupuncture and regulation of gastrointestinal function显示文摘In China, acupuncture has been considered an effective method for treating gastrointestinal(GI) dysfunction diseases for thousands of years. In fact, acupuncture has gained progressive acceptance from both practitioners and patients worldwide. However, the therapeutic effects and underlying mechanisms in treating GI dysfunction have not yet been established due to a lack of systematic and comprehensive review articles. Therefore, the aim of this review is to discuss the efficacy of acupuncture as a treatment for GI dysfunction and the associated underlying mechanisms. A search of Pub Med was conducted for articles that were published over the past 10 years using the terms 'acupuncture', 'gastrointestine', and other relevant keywords. In the following review, we describe the effect and underlying mechanisms of acupuncture on GI function from the perspectives of GI motility, visceral sensitivity, the GI barrier, and the brain-gut axis. The dual regulatory effects of acupuncture may manifest by promoting gastric peristalsis in subjects with low initial gastric motility, and suppressing peristalsis in subjects with active initial motility. In addition, the regulation of acupuncture on gastric motility may be intensitydependent. Our findings suggest that further studies are needed to investigate the effects and more systematic mechanisms in treating GI dysfunction, and to promote the application of acupuncture for the treatment of GI diseases.Hui Li Tian He Qian Xu Zhe Li Yan Liu Fang Li Bo-Feng Yang Cun-Zhi Liu 2015World Journal of Gastroenterology2015,21,27:41

18A life support-based comprehensive treatment regimen dramatically lowers the in-hospital mortality of patients with fulminant myocarditis: a multiple center study显示文摘Fulminant myocarditis(FM) has unacceptable high mortality. This study aimed to evaluate the therapeutic efficacy of a life support-based comprehensive treatment regimen(LSBCTR), a completely novel treatment regimen, for FM. A total of 169 FM patients recruited from January 2008 to December 2018 were divided into two groups: patients receiving LSBCTR(81 cases),which includes(i) mechanical life support(positive pressure respiration, intra-aortic balloon pump with or without extracorporeal membrane oxygenation),(ii) immunomodulation therapy using sufficient doses of glucocorticoids and immunoglobulins, and(iii) application of neuraminidase inhibitors, and those receiving conventional treatment(88 cases). The endpoints were in-hospital death and heart-transplantation. Of all the population, 44 patients(26.0%) died in hospitals. Inhospital mortality was 3.7%(3/81) for LSBCTR group and 46.6%(41/88) for traditional treatment(P<0.001). Early application of LSBCTR, mechanical life support, neuraminidase inhibitors, and immunomodulation therapy significantly contributed to reduction in in-hospital mortality. This study describes a novel treatment regimen for FM patients that dramatically reduces inhospital mortality. Its generalization and clinical application will efficiently save lives although further optimization is needed.This study offers an insight that virus infection induced inflammatory waterfall results in cardiac injury and cardiogenic shock and is the therapeutic target.Sheng Li Shengyong Xu Chenze Li Xiao Ran Guanglin Cui Mengying He Kun Miao Chunxia Zhao Jiangtao Yan Rutai Hui Ning Zhou Yan Wang Jiangang Jiang Jing Zhang Daowen Wang 2019Science China(Life Sciences)2019,62,3:43
19Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China显示文摘To control the spread of the 2019 novel coronavirus(COVID-19),China imposed nationwide restrictions on the movement of its population(lockdown)after the Chinese New Year of 2020,leading to large reductions in economic activities and associated emissions.Despite such large decreases in primary pollution,there were nonetheless several periods of heavy haze pollution in eastern China,raising questions about the well-established relationship between human activities and air quality.Here,using comprehensive measurements and modeling,we show that the haze during the COVID lockdown was driven by enhancements of secondary pollution.In particular,large decreases in NOx emissions from transportation increased ozone and nighttime NO_(3)radical formation,and these increases in atmospheric oxidizing capacity in turn facilitated the formation of secondary particulate matter.Our results,afforded by the tragic natural experiment of the COVID-19 pandemic,indicate that haze mitigation depends upon a coordinated and balanced strategy for controlling multiple pollutants.Xin Huang Aijun Ding Jian Gao Bo Zheng Derong Zhou Ximeng Qi Rong Tang Jiaping Wang Chuanhua Ren Wei Nie Xuguang Chi Zheng Xu Liangduo Chen Yuanyuan Li Fei Che Nini Pang Haikun Wang Dan Tong Wei Qin Wei Cheng Weijing Liu Qingyan Fu Baoxian Liu Fahe Chai Steven JDavis Qiang Zhang Kebin He 2021National Science Review2021,8,2:47
20Renewable Energy Transmission by HVDC Across the Continent:System Challenges and Opportunities显示文摘Rapid development of renewable energy in China is driving a major shift in the characteristics and control requirements of the electricity grid.Since the best renewable energy resources are far away from load centers in the east and southeast,transmission over long distances is required.Over 20 high-voltage DC(HVDC)transmission lines,with a combined capacity exceeding 150 GW,are in operation or are currently under construction.This rapid expansion of new generation and transmission capacities based on power electronics starts to change the characteristics of the grid,especially in areas where they concentrate,creating new stability problems and operational challenges.New system theories and technologies are required to support the development and operation of a future grid that relies more and more on power electronics.This paper highlights the characteristics of power electronics as used in renewable energy generation and HVDC transmission systems,discusses the impacts of these power-electronics-based assets on grid stability and operational requirements,and identifies opportunities for the development of both new system theories and system technologies to support a national energy policy that emphasizes the use of clean energy.Jian Sun Mingjie Li Zhigang Zhang Tao Xu Jingbo He Haijiao Wang Guanghui Li 2017CSEE Journal of Power and Energy Systems2017,3,4:43
