2The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
3Necessity and indications of invasive treatment for Budd-Chiari syndrome显示文摘BACKGROUND:The development of collaterals in Budd-Chiari syndrome has been described and these collaterals play an important role in the presentation of this disease.These collaterals are diagnostic and their use in management strategy has never been evaluated.This study aimed to investigate the indications,feasibility and necessity of invasive treatment for patients with Budd-Chiari syndrome and to determine whether such a strategy is necessary for optimal management.METHODS:Twenty-nine patients who had been treated at our unit were enrolled in this study.Based on physical and biochemical examination,and hemodynamic compensation by collaterals,18 patients underwent radiological intervention (group A),while the other 11 had no invasive treatment (group B).The related hemodynamic parameters were acquired when percutaneous angiography was performed.RESULTS:In group A,all patients underwent successfully inferior vena cava (IVC) balloon angioplasty with or without stenting.Four patients also underwent hepatic vein angioplasty.In these patients,the mean IVC pressure before and after treatment was statistically different (29.3±9.2 vs 15.1±4.6 mmHg,P<0.01).The mean IVC pressure was much lower in group B than in group A (12.9±2.4 vs 29.3±9.2 mmHg,P<0.01),but there was no difference from that of the patients after radiological treatment (12.9±2.4 vs 15.1±4.6 mmHg,P>0.05).Median follow-up was 32.3 months (mean 21.3 months;range 3-61 months).In the course of follow-up,the patients in group A survived with good systemic status except for re-stenosis in one patient who underwent re-canalization of the IVC.In group B,10 patients had good systemic status except one patient who had a meso-caval shunt because of deterioration.CONCLUSIONS:The rationale of 'early diagnosis and early treatment' is not suitable for all patients with Budd-Chiari syndrome.Satisfactory survival can be achieved in some patients without invasive treatment,who are completely compensated by rich collaterals.Nonetheless,a positive treatment procedure should be performed if the patient's situation worsens in the course of regular follow-up.Department of General Surgery (Fu Y,Sun YL,Ma XX,Xu PQ,Feng LS,Tang Z and Luo CH),Institute of Hepatic Vascular Disease (Sun YL),Department of Radiological Intervention (Guan S and Wang ZW),First Affiliated Hospital,Zhengzhou University School of Medicine,Zhengzhou 450052,China 2011Hepatobiliary & Pancreatic Diseases International2011,10,3:10
4Endoscopic sphincterotomy associated cholangitis in patients receiving proximal biliary self-expanding metal stents显示文摘BACKGROUND: Endoscopic biliary stent placement during the procedure of endoscopic retrograde cholangiopancreatography (ERCP) is preferred to provide biliary drainage for unresectable malignant biliary obstruction. There is considerable controversy over the use of endoscopic sphincterotomy (ES) prior to stent placement. This study aimed to determine whether ES before intraductal self-expanding metal stent (SEMS) placement affects the clinical outcome and complications in patients with proximal malignant obstructive biliary diseases. METHODS: In a prospective randomized controlled trial, 82 patients with inoperable malignant biliary strictures were randomly assigned to biliary stenting groups with or without ES. Resolution of jaundice and the incidence of complications including acute cholangitis, pancreatitis and stent occlusion within 6 months were evaluated. RESULTS: SEMSs were successfully deployed in all patients, resulting in clinical and biochemical improvement of obstructive symptoms in both groups. The incidence of cholangitis was higher in the ES group than in the non-ES group (58.5% vs 31.7%, P=0.015). The interval between stent placement and the first acute cholangitis was much shorter in the ES group than in the non-ES group (P=0.024). The use of ES increased the incidence of cholangitis (P=0.004, risk ratio, 8.196). The rate of post-ERCP pancreatitis after stent placement was greater in the non-ES group than in the ES group (31.7% vs 9.8%, P=0.014). No significant differences were found in the rate of restenosis and the mortality rate between the two groups.CONCLUSIONS: ES prior to intraductal SEMS placement was associated with an increased incidence of acute cholangitis. ES should be carefully evaluated prior to its use in patients with proximal malignant obstructive biliary diseases.Hui Zhou, Lei Li, Feng Zhu, Sheng-Zheng Luo, Xiao-Bo Cai,Xin-Jian Wan Department of Gastroenterology, Shanghai First People’s Hospital, Shanghai Jiaotong University, Shanghai 200080, China 2012Hepatobiliary & Pancreatic Diseases International2012,11,6:8
5Percutaneous transhepatic metal versus plastic biliary stent in treating malignant biliary obstruction: a multiple center investigation显示文摘OBJECTIVE: To compare the efficacy of metal versus plastic biliary stent implantation in the treatmentof malignant biliary obstruction.METHODS: Percutaneous transhepatic self-expandable metal stent (MS, n=61) and 10F plastic stent(PS, n=34) were placed in 95 patients with malignant biliary obstruction in three hospitals of Guangdongprovince. All patients were followed up until death or at least one year after the procedure. Kaplan-Meieranalysis was used to compare the survival of the patients and the rates of stent patency.RESULTS: The 30-day mortality rate was lower in the MS group (6/61, 9.8%) than in the PS group(9/34, 26.5%, P<0.05). The 30-day reobstruction rate and the complication rate were 15.0%, 16.4%in the MS group and 32. 4%, 29. 4% in the PS group, respectively (P<0. 01). The median patencyperiod of stents and median survival period of the patients were 230 days, 224 days in the MS group and90 days, 94 days in the PS group, respectively (P<0. 01).CONCLUSION: Metal stent is clinically superior to plastic stent in the treatment of malignant biliaryobstruction.Yuan-Xing Guo Yan-Hao Li Yong Chen Ping-Yan Chen Peng-Fei Luo Yong Li Hong Shan Zai-Bo Jiang the Department of Interventional Radiology, Nanfang Hospital, First Military Medical University, Guangzhou 510515, China Department of Medical Statistics, First Military Medical University, Guangzhou 510515, China Department of Radiology, Guangdong Provincial People’s Hospital, Guangzhou 510080, China Department of Radiology, Third Affiliated Hospital of Sun Yat-Sen University of Medical Sciences, Guangzhou 510630, China 2003Hepatobiliary & Pancreatic Diseases International2003,2,4:8
6桑叶多糖对早期断奶仔猪生长性能、腹泻、血液指标和肠道菌群的影响显示文摘研究旨在探讨日粮补充桑叶多糖(MLPs)对早期断奶仔猪生长性能、腹泻、血液生化指标和肠道菌群的影响。共选取(28±2)日龄、体重为(9.18±0.46)kg的'杜洛克×长白×约克夏'杂交断奶仔猪150头,随机分成5个处理组,每组6个重复,每个重复5头猪。饮食处理如下:对照组(CT):基础日粮(BD);低剂量桑叶多糖组(LT):0.3 g·kg-1MLPs+BD;中剂量桑叶多糖组(MT):0.6 g·kg-1MLPs+BD;高剂量桑叶多糖组(HT):0.9 g·kg-1MLPs+BD;抗生素处理组(AT):0.15 g·kg-1金霉素+BD。分别在第0、10、21天的早晨,每头猪空腹测量体重并记录采食量,这些数据用来计算平均日增重(ADG)、平均日采食量(ADFI)和料重比(F/G)。每天两次(上午和下午)对每头仔猪的腹泻状况进行检查并记录。在试验结束时,收集血液样本用于生化分析,并收集盲肠、结肠和直肠内容物进行识别和量化相关的肠道菌群。研究结果表明,MLPs处理组间的日增重、平均日采食量和料重比无显著差异(P>0.05),但低剂量组(LT)、中剂量组(MT)、高剂量组(HT)的平均日采食量高于对照组(CT)和抗生素组(AT)。并且,LT、MT和HT组的料重比低于CT和AT组。与CT和AT组相比,LT、MT和HT组仔猪的腹泻发病率也显著降低(P<0.05)。生化分析表明,MLPs各处理组仔猪的血糖(GLU)水平均显著低于CT或AT组(P<0.05)。MT和HT组血液尿素氮(BUN)水平与CT和AT组存在显著差异(P<0.05),HT组T3水平显著高于CT和AT组(P<0.05)。虽然MLPs各处理组的T4水平与AT组并没有显著差异(P>0.05),但MT组的胰岛素样生长因子Ⅰ(IGF-Ⅰ)和生长激素(GH)水平较CT或AT组均显著升高(P<0.05)。LT、MT和HT 3组在抑制肠道大肠杆菌生长和促进肠道乳酸杆菌和双歧杆菌生长的整体效果上均优于CT和AT组。值得注意的是,与CT和AT组相比,HT组(0.9 g·kg-1MLPs)对抑制肠道大肠杆菌以及促进肠道有益菌群具有更显著效果(P<0.05)。结果表明,日粮添加桑叶多糖可以改善早期断奶仔猪肠道菌群的生态环境,降低腹泻率,提高整体生长性能。Zhao X J Lin L Luo Q L Ye M Q Luo G Q Kuang Z S 2015饲料博览2015,0,7:7
7Evolution of permafrost in China during the last 20 ka显示文摘The formation and evolution of permafrost in China during the last 20 ka were reconstructed on the basis of large amount of paleo-permafrost remains and paleo-periglacial evidence, as well as paleo-glacial landforms, paleo-flora and paleofauna records. The results indicate that, during the local Last Glacial Maximum(LLGM) or local Last Permafrost Maximum(LLPMax), the extent of permafrost of China reached 5.3×106-5.4×106 km2, or thrice that of today, but permafrost shrank to only0.80×106-0.85×106 km2, or 50% that of present, during the local Holocene Megathermal Period(LHMP), or the local Last Permafrost Minimum(LLPMin). On the basis of the dating of periglacial remains and their distributive features, the extent of permafrost in China was delineated for the two periods of LLGM(LLPMax) and LHMP(LLPMin), and the evolution of permafrost in China was divided into seven periods as follows:(1) LLGM in Late Pleistocene(ca. 20000 to 13000-10800 a BP)with extensive evidence for the presence of intensive ice-wedge expansion for outlining its LLPMax extent;(2) A period of dramatically changing climate during the early Holocene(10800 to 8500-7000 a BP) when permafrost remained relatively stable but with a general trend of shrinking areal extent;(3) The LHMP in the Mid-Holocene(8500-7000 to 4000-3000 a BP)when permafrost degraded intensively and extensively, and shrank to the LLPMin;(4) Neoglaciation during the late Holocene(4000-3000 to 1000 a BP, when permafrost again expanded;(5) Medieval Warming Period(MWP) in the late Holocene(1000-500 a BP) when permafrost was in a relative decline;(6) Little Ice Age(LIA) in the late Holocene(500-100 a BP), when permafrost relatively expanded, and;(7) Recent warming(during the 20 th century), when permafrost continuously degraded and still is degrading. The paleo-climate, geography and paleopermafrost extents and other features were reconstructed for each of these seven periods.Huijun JIN Xiaoying JIN Ruixia HE Dongliang LUO Xiaoli CHANG Shaoling WANG Sergey S MARCHENKO Sizhong YANG Chaolu YI Shijie LI Stuart A HARRIS 2019Science China Earth Sciences2019,62,8:6
8Pulmonary infection control window in treatment of severe respiratory failure of chronic obstructive pulmonary diseases: a prospective, randomized controlled, multi-centred study显示文摘Background Early withdraw from invasive mechanical ventilation (MV) followed by noninvasive MV is a new strategy for changing modes of treatment. This study was conducted to estimate the feasibility and the efficacy of early extubation and sequential noninvasive MV commenced at beginning of pulmonary infection control window in patients with exacerbated hypercapnic respiratory failure caused by chronic obstructive pulmonary diseases (COPD). Methods A prospective, randomized controlled study was conducted in eleven teaching hospitals' respiratory or medical intensive care units in China. Ninety intubated COPD patients with severe hypercapnic respiratory failure triggered by pulmonary infection (pneumonia or purulent bronchitis) were involved in the study. When the pulmonary infection had been controlled by antibiotics and comprehensive therapy, the 'pulmonary infection control window (PIC window)' has been reached. Each case was randomly assigned to study group (extubation and noninvasive MV via facial mask immediately) or control group (invasive MV was received continuously after PIC window by using conventional weaning technique).Results Study group (n=47) and control group (n=43) had similar clinical characteristics initially and at the time of PIC window. Compared with control group, study group had shorter duration of invasive MV [(6.4±4.4) days vs (11.3±6.2) days, P=0.000], lower rate of ventilator associated pneumonia (VAP) (3/47 vs 12/43, P=0.014), fewer days in ICU [(12±8) days vs (16±11) days, P=0.047] and lower hospital mortality (1/47 vs 7/43, P=0.025).Conclusions In COPD patients requiring intubation and invasive MV for hypercapnic respiratory failure, which is exacerbated by pulmonary infection, early extubation followed by noninvasive MV initiated at the start of PIC window may decrease significantly the duration of invasive MV, the risk of VAP and hospital mortality.Wang, C Zhan, QY Cao, ZX Wei, LQ Cheng, ZZ Liu, S Zhang, JL Chen, RC Luo, Q Niu, SF Zhu, L Wu, DW Fang, BM Wu, TH Wang, CZ Liu, YN 2005Chinese Medical Journal2005,,19:6
9Effects of Dan-Shao-Hua-Xian on the expression of collagen type I and III in rats with hepatic fibrosis显示文摘BACKGROUND: Hepatic fibrosis is the common patholo gical change in various chronic liver diseases,and its major cause is the imbalance between the production and degra dation of the extracellular matrix, which is mainly com posed of collagens. Dan-Shao-Hua-Xian ( DSHX) cap sule, a traditional Chinese herbal compound, has shown marked preventive effects on hepatic fibrosis in rats in our previous studies. The present study was designed to further investigate its therapeutic actions on hepatic fibrosis in rats and its possible mechanisms. METHODS: Eighty male Wistar rats were randomly divid- ed into normal control group, hepatic fibrosis group, non DSHX-treated group, low-dose-treated group, and high dose-treated group. The rat models of hepatic fibrosis were established by subcutaneous injecton of CC14 , drinking al- cohol , giving diet of hyperliprosis and hypoprotein for 8 weeks. The two DSHX-treated groups were treated respec- tively with low dose (0.5 g/kg) and high dose (1.0 g/kg) of DSHX capsule p. o. everyday for 8 weeks. At the end of the experiment, liver indexes were calculated in each group in addition to the levels of the serum hyaluronic acid and alanine aminotransferase. Their degree of hepatic fibrosis and urinary excretion of hydroxyproline and expression of collagen , were detected. RESULTS: Comparison of the indexes of the hepatic fibro- sis group and non-DSHX-treated group revealed that the liver indexes, levels of serum hyaluronic acid and alanine aminotransferase, and stage of hepatic fibrosis were all sig- nificantly reduced in the two DSHX treated groups. The urinary excretion of hydroxyproline was increased and the expression of collagen I and HI in liver tissue was lessened. These alterations were more obviously observed in the high-dose-treated group. CONCLUSION: DSHX capsule has certain therapeutic effect on hepatic fibrosis in rats.Xiao-Xia Geng, Qin Yang, Ru-Jia Xie, Xin-Hua Luo, Cheng-Xiu Li and Ming-Liang Cheng Guizhou, China Department of Infectious Diseases, Affiliated Hospital of Guiyang Medical College Department of Pathophysiology, Guiyang Medical College Depart- ment of Infectious Diseases, People’ s Hospital of Guizhou Province and Department of Pharmacology, Guiyang Medical College 2004Hepatobiliary & Pancreatic Diseases International2004,3,4:4

12DISTRIBUTION PATTERNS OF LEAF AREA INDEX FOR MAJOR CONIFEROUS FOREST TYPES IN CHINA显示文摘Leaf area index (LAI) of natural vegetation is recognized as the most important variable for measuring vegetation structure over large areas, and for relating it to energy and mass exchange, which has been successfully estimated from satellite resolution sensors. In this paper, according to the statistical analysis based on a lot of forest plots, the mathematical models of LAI distribution patterns in the hydro thermal spaces for five coniferous forest types in China were established. For the cold temperate larch forests growing in the dry and cold climate, their LAI increases with the increasing of warm index and precipitation in the way of hyperbolic quadratic surface. For the cold temperate spruce fir forests and temperate Pinus tabulaeformis forests, their LAI is negatively related to the annual mean air temperature in the way of the natural exponential curve, in order to adapt to the water oppressed environments. For the subtropical Pinus massoniana forests and Cunninghamia lanceolata forests growing in the warm and moist climate, their LAI is related to the annual mean air temperature in the way of the parabolic quadratic curve.Luo Tianxiang Li Wenhua Zhao Shidong Commission for Integrated Survey of Natural Resources, CAS, Beijing 100101 The People’s Republic of China 1997Journal of Geographical Sciences1997,7,4:4
13Polysaccharide-based nanomedicines for cancer immunotherapy:A review显示文摘Cancer immunotherapy is an effective antitumor approach through activating immune systems to eradicate tumors by immunotherapeutics.However,direct administration of“naked”immunotherapeutic agents(such as nucleic acids,cytokines,adjuvants or antigens without delivery vehicles)often results in:(1)an unsatisfactory efficacy due to suboptimal pharmacokinetics;(2)strong toxic and side effects due to low targeting(or off-target)efficiency.To overcome these shortcomings,a series of polysaccharide-based nanoparticles have been developed to carry immunotherapeutics to enhance antitumor immune responses with reduced toxicity and side effects.Polysaccharides are a family of natural polymers that hold unique physicochemical and biological properties,as they could interact with immune system to stimulate an enhanced immune response.Their structures offer versatility in synthesizing multifunctional nanocomposites,which could be chemically modified to achieve high stability and bioavailability for delivering therapeutics into tumor tissues.This review aims to highlight recent advances in polysaccharide-based nanomedicines for cancer immunotherapy and propose new perspectives on the use of polysaccharide-based immunotherapeutics.Yujun Zeng Yufan Xiang Ruilong Sheng Helena Tomás João Rodrigues Zhongwei Gu Hu Zhang Qiyong Gong Kui Luo 2021Bioactive Materials2021,6,10:3

15Fast, green microwave-assisted synthesis of single crystalline Sb_2Se_3 nanowires towards promising lithium storage显示文摘In this work, a fast(0.5 h), green microwave-assisted synthesis of single crystalline Sb_2Se_3 nanowires was developed. For the first time we demonstrated a facile solvent-mediated process, whereby intriguing nanostructures including antimony selenide(Sb_2Se_3) nanowires and selenium(Se) microrods can be achieved by merely varying the volume ratio of ethylene glycol(EG) and H_2O free from expensive chemical and additional surfactant. The achieved uniform Sb_2Se_3 nanowire is single crystalline along [001]growth direction with a diameter of 100 nm and a length up to tens of micrometers. When evaluated as an anode of lithium-ion battery, Sb_2Se_3 nanowire can deliver a high reversible capacity of 650.2 m Ah g^(-1) at 100 mA g^(-1) and a capacity retention of 63.8% after long-term 1000 cycles at 1000 mA g^(-1), as well as superior rate capability(389.5 m Ah g^(-1) at 2000 mA g^(-1)). This easy solvent-mediated microwave synthesis approach exhibits its great universe and importance towards the fabrication of high-performance metal chalcogenide electrode materials for future low-cost, large-scale energy storage systems.Wen Luo Jean-Jacques Gaumet Pierre Magri Sébastien Diliberto Feng Li Pascal Franchetti Jaafar Ghanbaja Liqiang Mai 2019Journal of Energy Chemistry2019,28,3:3
16Further geological and palaeoanthropological investigations at the Maludong hominin site, Yunnan Province, Southwest China显示文摘Three-dimensional mapping and section work undertaken by us in 2008 have identified 11 stratigraphic units at Maludong site.AMS radiocarbon dating of charcoal established an accurate and internally consistent age profile for the sequence of 17.8±0.2 ka to 13.2±0.1 ka.Archaeomagnetic analysis showed changes in externally derived pedogenically enhanced material consistent with a warming in climate between the cold period of Henrich Event 1 and the B lling-Aller d interstadial.Human remains recovered during the 1989 excavation were derived from a deposit dating to this interstadial,or between 14.3±0.3 ka and 13.5±0.1 ka.Anthropogenic features,including burnt rocks,baked sediment and thick charcoal and ash layers,were identified and examined through archaeomagnetic analysis.Two monkey fossils are described here,one of them being reassigned from Macaca robustus to M.aff.M.assamensis.They confirm the young age of the site and also show signs of anthropogenic alteration in the form of burning.Additional human cranial remains are reported for the first time and new data are provided for some specimens described previously.A range of new features is identified that strengthen the affinities of the Maludong remains to archaic humans.The presence of this globally unique mosaic of archaic and modern features raises important questions about human evolutionary history in East Asia during the Late Upper Pleistocene.JI XuePing CURNOE Darren BAO ZhenDe HERRIES Andy I R FINK David ZHU YunSheng HELLSTROM John LUO Yun TACON Paul S C 2013Chinese Science Bulletin2013,58,35:3
17Therapeutic efficacy and bone marrow protection of the mdr1 gene and over-dose chemotherapy with doxorubicin for rabbits with VX2 hepatocarcinoma显示文摘BACKGROUND : Malignant tumors are common diseases threatening to the health and life of human being. Clinically, the multidrug resistance of tumor cells and bone marrow depression caused by chemotherapeutic agents are the main obstacles to the treatment of tumors, and both are related to the mdr1 gene. The over expression of the mdr1 gene in tumor cells contributes to the multidrug resistance of malignant tumor cells. With little expression of the mdr1 gene, bone marrow cells particularly susceptible to multidrug resistance-sensitive agents, which cause serious toxicity in bone marrow. This study was undertaken to assess therapeutic efficacy of transplantation of bone marrow mononuclear cells transferred with the mdr1 gene and over-dose chemotherapy with doxorubicin for VX2 hepatocarcinoma of rabbits. METHODS: The mdr1 gene was transferred into the bone marrow mononuclear cells of rabbits, which was co- cultured with retroviral vector-containing supernatant, and the cells were autotransplanted into a rabbit model with VX2 hepatocarcinoma. After chemotherapy with doxorubicin, the protective effects of the mdr1 gene and therapeutic efficacy of over-dose chemotherapy were observed. RESULTS: The mdr1 gene was transferred successfully into the bone marrow mononuclear cells, with a transduction efficiency of 35%. After autotransplantation, the mdr1 gene was expressed functionally in bone marrow with a positive rate of 8%, indicating that the gene played animportant role in bone marrow protection. The rabbits with VX2 hepatocarcinoma, which had received the mdr1 gene-transduced cells, survived after chemotherapy with a 3-fold dose of adriamycin, and their white blood cell counts were (4.26±1.03)×104/L. Since hepatocarcinoma cells were eradicated, the survival time (97.00±46.75 d) of the rabbits was extended (P<0.05) and the healing rate of the tumor was increased (P<0.05). CONCLUSIONS: The transferring of the mdr1 gene into bone marrow mononuclear cells could confer chemoprotection to bone marrow, and over-dose chemotherapy could be prescribed for the treatment of malignant tumors.Yi Wang, Xian-Qing Jin, Shan Wang, Qiao Wang, Qing Luo and Xiao-Ji Luo Department of General Surgery Department of Ultrasound , Chongqing Children’s Hospital, Chongqing University of Medical Sciences, Chongqing 400014, China 2006Hepatobiliary & Pancreatic Diseases International2006,5,4:3

19Typical Survey and Research on Returning-home Migrant Workers' Entrepreneurship in Jiangxi Province under Post-financial Crisis显示文摘In order to study the entrepreneurship situation of Jiangxi return migrant workers after the financial crisis,we have conducted a survey on 107 entrepreneurial return migrant workers in 6 counties of Jiangxi Province.The results show that the return of migrant workers is mainly attributed to personal factors,while social factors are also very important.The major difficulties facing return migrant workers are the funding difficulties,complicated formalities to start a business,difficulty in safeguarding their rights and interests,their own low quality and so on.The support needed by the return migrant workers from the government is manifested in five aspects,say,to improve the service and management for the entrepreneurship of migrant workers,to provide financing policy support,to increase the preferential fiscal and taxation policies,to enhance the entrepreneurship training and to provide preference for the return migrant workers to use land.OUYANG Zhang-sun1,ZHANG Xin-zhi2,WANG Run-qun3,LUO Feng1,SHEN Ai-guo1,WU Xing-lin1 1.Jiangxi Biotech Vocational College,Nanchang 330299,China 2.The Research Center of the Central China’s Economic Development,Nanchang University,Nanchang 330047,China 3.Jizhou Agricultural Bureau,Jizhou District,Ji’an City in Jiangxi Province,Ji’an 343000,China 2010Asian Agricultural Research2010,2,10:2
