4Expression of Livin and vascular endothelial growth factor in different clinical stages of human esophageal carcinoma显示文摘AIM: To investigate the role of Livin and vascular endothelial growth factor (VEGF) in human esophageal carcinoma, and analyze its relationship to clinical stages. METHODS: Expression of Livin in fresh esophageal cancer tissues was detected by immunohistochemistry (IHC), Western blotting and reverse transcriptase-polymerase chain reaction (RT-PCR), and VEGF by Western blotting and RT-PCR. All statistical analyses were performed by SPSS version 11.0. RESULTS: Livin positivity was also significantly correlated with tumor stages, increasing with tumor progression. Expression of Livin and VEGF increased with the process of esophageal carcinoma. In the fourth clinical stage, expression of Livin and VEGF was the most significant. Expression of Livin was positively correlated with VEGF. CONCLUSION: Over-expression of Livin and VEGF contributes to the pathogenesis of esophageal carcinoma.Li Chen Guo-Sheng Ren Fan Li Shan-Quan Sun 2008World Journal of Gastroenterology2008,14,37:41
5Recovery of iron from high phosphorus oolitic iron ore using coal-based reduction followed by magnetic separation显示文摘Oolitic iron ore is one of the most important iron resources. This paper reports the recovery of iron from high phosphorus oolitic iron ore using coal-based reduction and magnetic separation. The influences of reduction temperature, reduction time, C/O mole ratio, and CaO content on the metallization degree and iron recovery were investigated in detail. Experimental results show that reduced products with the metallization degree of 95.82% could be produced under the optimal conditions (i.e., reduction temperature, 1250℃; reduction time, 50 min; C/O mole ratio, 2.0; and CaO content, 10wt%). The magnetic concentrate containing 89.63wt% Fe with the iron recovery of 96.21% was obtained. According to the mineralogical and morphologic analysis, the iron minerals had been reduced and iron was mainly enriched into the metallic iron phase embedded in the slag matrix in the form of spherical particles. Apatite was also reduced to phosphorus, which partially migrated into the metallic iron phase.Yong-sheng Sun Yue-xin Han Peng Gao Ze-hong Wang Duo-zhen Ren 2013International Journal of Minerals,Metallurgy and Materials2013,20,5:43

7Uptake, Subcellular Distribution, and Chemical Forms of Cadmium in Wild-Type and Mutant Rice显示文摘Wild-type(Zhonghua 11) and mutant rice(Oryza sativa L.) plants were used to investigate the effect of cadmium(Cd) application on biomass production,to characterize the inffux of Cd from roots to shoots,and to determine the form,content,and subcellular distribution of Cd in the roots,leaf sheaths,and leaves of the rice plants.Seedlings were cultivated in a nutrient solution and were treated with 0.5 mmol L-1 of Cd2+ for 14 d.The sensitivity of rice plants to Cd toxicity was tested by studying the changes in biomass production and by observing the onset of toxicity symptoms in the plants.Both the wild-type and mutant rice plants developed symptoms of Cd stress.In addition,Cd application significantly(P ≤ 0.01) decreased dry matter production of roots,leaf sheaths,and leaves of both types,especially the mutant.The Cd content in roots of the mutant was significantly(P ≤ 0.05) higher than that of the wild-type rice.However,there was no significant di?erence in the Cd content of roots,leaf sheaths,and leaves between the wild-type and mutant rice.Most of the Cd was bound to the cell wall of the roots,leaf sheaths,and leaves,and the mutant had greater Cd content in cell organelles than the wild type.The uneven subcellular distribution could be responsible for the Cd sensitivity of the mutant rice.Furthermore,different chemical forms of Cd were found to occur in the roots,leaf sheaths,and leaves of both types of rice plants.Ethanol-,water-,and NaCl-extractable Cd had greater toxicity than the other forms of Cd and induced stunted growth and chlorosis in the plants.The high Cd content of the toxic forms of Cd in the cell organelles could seriously damage the cells and the metabolic processes in mutant rice plants.HE Jun-Yu ZHU Cheng REN Yan-Fang YAN Yu-Ping CHENG Chang JIANG De-An SUN Zong-Xiu 2008Pedosphere2008,18,3:37
8Contemporary crustal deformation of the Chinese continent and tectonic block model显示文摘We obtain the preliminary result of crustal deformation velocity field for the Chinese con-tinent by analyzing GPS data from the Crustal Motion Observation Network of China (CMONOC), particularly the data from the regional networks of CMONOC observed in 1999 and 2001. We de-lineate 9 tectonically active blocks and 2 broadly distributed deformation zones out of a denseGPS velocity field, and derive block motion Euler poles for the blocks and their relative motionrates. Our result reveals that there are 3 categories of deformation patterns in the Chinese conti-nent. The first category, associated with the interior of the Tibetan Plateau and the Tianshan oro-genic belt, shows broadly distributed deformation within the regions. The third category, associatedwith the Tarim Basin and the region east of the north-south seismic belt of China, shows block-likemotion, with deformation accommodated along the block boundaries only. The second category, mainly associated with the borderland of the Tibetan Plateau, such as the Qaidam, Qilian, Xining(in eastern Qinghai), and the Diamond-shaped (in western Sichuan and Yunnan) blocks, has thedeformation pattern between the first and the third, i.e. these regions appear to deform block-like,but with smaller sizes and less strength for the blocks. Based on the analysis of the lithosphericstructures and the deformation patterns of the regions above, we come to the inference that thedeformation modes of the Chinese continental crust are mainly controlled by the crustal structure.The crust of the eastern China and the Tarim Basin is mechanically strong, and its deformationtakes the form of relative motion between rigid blocks. On the other hand, the northward indentation of the Indian plate into the Asia continent has created the uplift of the Tibetan Plateau and the Tianshan Mountains, thickened their crust, and raised the temperature in the crust. The lower crust thus has become ductile, evidenced in low seismic velocity and high electric conductivity observed. The brittle part of the crust, driven by the visco-plastic flow of the lower crust, deforms extensively at all scales. The regions of the second category located at the borderland of the Tibetan Plateau are at the transition zone between the regions of the first and the third categories in terms of the crustal structure. Driven by the lateral boundary forces, their deformation style is also between the two, in the form of block motion and deformation with smaller blocks and less internal strength.WANG Min (王 敏) SHEN Zhengkang (沈正康) NIU Zhijun (牛之俊) ZHANG Zusheng (张祖胜) SUN Hanrong (孙汉荣) GAN Weijun (甘卫军) WANG Qi (王 琪) REN Qun (任 群) 2003Science China Earth Sciences2003,46,z2:33
9Hydrophobicity mechanism of non-smooth pattern on surface of butterfly wing显示文摘Twenty-nine species (24 genera, 6 families) of butterflies typical and common in northeast China were selected to make qualitative and quantitative studies on the pattern, hydrophobicity and hydrophobicity mechanism by means of scanning electron microscopy and contact angle measuring system. The scale surface is composed of submicro-class vertical gibbosities and horizontal links. The distance of scale is 48—91 μm, length 65—150 μm, and width 35—70 μm. The distance of submicro-class vertical gib-bosities on scale is 1.06—2.74 μm, height 200—900 nm, and width 200—840 nm. The better hydropho-bicity on the surface of butterfly wing (static contact angle 136.3°—156.6°) is contributed to the co-effects of micro-class scale and submicro-class vertical gibbosities on the wing surface. The Cassie equation was revised, and new mathematical models and equations were established.FANG Yan SUN Gang WANG TongQing CONG Qian REN LuQuan 2007Chinese Science Bulletin2007,52,5:31

13Oridonin induces apoptosis in gastric cancer through Apaf-1,cytochrome c and caspase-3 signaling pathway显示文摘AIM:To investigate the effect and mechanism of oridonin on the gastric cancer cell line HGC-27 in vitro.METHODS:The inhibitory effect of oridonin on HGC-27 cells was detected using the 3-(4,5-dimethylthiazol2-yl)-2,5-diphenyl tetrazolium bromide assay.After treatment with 10 μg/mL oridonin for 24 h and 48 h,the cells were stained with acridine orange/ethidium bromide.The morphologic changes were observed under an inverted fluorescence microscope.DNA fragmen-tation(a hallmark of apoptosis) and lactate dehydrogenase activity were examined using DNA ladder assay and lactate dehydrogenase-release assay.After treated with oridonin(0,1.25,2.5,5 and 10 μg/mL),HGC-27 cells were collected for anexin V-phycoerythrin and 7-amino-actinomycin D double staining and tested by flow cytometric analysis,and oridonin-induced apoptosis in HGC-27 cells was detected.After treatment with oridonin for 24 h,the effects of oridonin on expression of Apaf-1,Bcl-2,Bax,caspase-3 and cytochrome c were also analyzed using reverse-transcript polymerase chain reaction(RT-PCR) and Western blotting.RESULTS:Oridonin significantly inhibited the proliferation of HGC-27 cells in a dose-and time-dependent manner.The inhibition rates of HGC-27 treated with four different concentrations of oridonin for 24 h(1.25,2.5,5 and 10 μg/mL) were 1.78% ± 0.36%,4.96% ± 1.59%,10.35% ± 2.76% and 41.6% ± 4.29%,respectively,which showed a significant difference(P < 0.05).The inhibition rates of HGC-27 treated with oridonin at the four concentrations for 48 h were 14.77% ± 4.21%,21.57% ± 3.75%,30.31% ± 4.91% and 61.19% ± 5.81%,with a significant difference(P < 0.05).The inhibition rates of HGC-27 treated with oridonin for 72 h at the four concentrations were 25.77% ± 4.85%,31.86% ± 3.86%,48.30% ± 4.16% and 81.80% ± 6.72%,with a significant difference(P < 0.05).Cells treated with oridonin showed typical apoptotic features with acridine orange/ethidium bromide staining.After treatment with oridonin,the cells became round,shrank,and developed small buds around the nuclear membrane while forming apoptotic bodies.Lactate dehydrogenase(LDH) release assay showed that after treated with 1.25 μg/mL and 20 μg/mL oridonin for 24 h,LDH release of HGC-27 caused by apoptosis increased from 22.94% ± 3.8% to 52.68% ± 2.4%(P < 0.001).However,the change in the release of LDH caused by necrosis was insignificant,suggesting thatthe major cause of oridonin-induced HGC-27 cell death was apoptosis.Flow cytometric analysis also revealed that oridonin induced significant apoptosis compared with the controls(P < 0.05).And the apoptosis rates of HGC-27 induced by the four different concentrations of oridonin were 5.3% ± 1.02%,12.8% ± 2.53%,28.5% ± 4.23% and 49.6% ± 3.76%,which were in a dose-dependent manner(P < 0.05).After treatment for 24 h,DNA ladder showed that oridonin induced a significant increase in DNA fragmentation in a dosedependent manner.RT-PCR revealed that mRNA expression levels were up-regulated compared with the controls in caspase-3(0.917 ± 0.103 vs 0.357 ± 0.019,P < 0.05),cytochrome c(1.429 ± 0.111 vs 1.002 ± 0.014,P < 0.05),Apaf-1(0.688 ± 0.101 vs 0.242 ± 0.037,P < 0.05) and Bax(0.856 ± 0.101 vs 0.278 ± 0.027,P < 0.05)(P < 0.05),whereas down-regulated in Bcl-2(0.085 ± 0.012 vs 0.175 ± 0.030,P < 0.05).Western blotting analysis also confirmed this result.CONCLUSION:Apoptosis of HGC-27 induced by oridonin may be associated with differential expression of Apaf-1,caspase-3 and cytochrome c,which are highly dependent upon the mitochondrial pathway.Ke-Wang Sun Ying-Yu Ma Tian-Pei Guan Ying-Jie Xia Chang-Ming Shao Le-Gao Chen Ya-Jun Ren Hai-Bo Yao Qiong Yang Xu-Jun He 2012World Journal of Gastroenterology2012,18,48:25
14Relative Contributions of Boundary-Layer Meteorological Factors to the Explosive Growth of PM2.5 during the Red-Alert Heavy Pollution Episodes in Beijing in December 2016显示文摘Based on observations of urban mass concentration of fine particulate matter smaller than 2.5 μm in diameter(PM_(2.5)), ground meteorological data, vertical measurements of winds, temperature, and relative humidity(RH), and ECMWF reanalysis data, the major changes in the vertical structures of meteorological factors in the boundary layer(BL) during the heavy aerosol pollution episodes(HPEs) that occurred in winter 2016 in the urban Beijing area were analyzed. The HPEs are divided into two stages: the transport of pollutants under prevailing southerly winds, known as the transport stage(TS), and the PM_(2.5) explosive growth and pollution accumulation period characterized by a temperature inversion with low winds and high RH in the lower BL, known as the cumulative stage(CS). During the TS, a surface high lies south of Beijing, and pollutants are transported northwards. During the CS, a stable BL forms and is characterized by weak winds, temperature inversion, and moisture accumulation. Stable atmospheric stratification featured with light/calm winds and accumulated moisture(RH > 80%) below 250 m at the beginning of the CS is closely associated with the inversion, which is strengthened by the considerable decrease in near-surface air temperature due to the interaction between aerosols and radiation after the aerosol pollution occurs. A significant increase in the PLAM(Parameter Linking Aerosol Pollution and Meteorological Elements) index is found, which is linearly related to PM mass change. During the first 10 h of the CS, the more stable BL contributes approximately 84% of the explosive growth of PM_(2.5) mass. Additional accumulated near-surface moisture caused by the ground temperature decrease, weak turbulent diffusion, low BL height, and inhibited vertical mixing of water vapor is conducive to the secondary aerosol formation through chemical reactions, including liquid phase and heterogeneous reactions, which further increases the PM_(2.5) concentration levels. The contribution of these reaction mechanisms to the explosive growth of PM_(2.5) mass during the early CS and subsequent pollution accumulation requires further investigation.junting zhong xiaoye zhang yaqiang wang junying sun yangmei zhang jizhi wang kaiyan tan xiaojing shen haochi che lu zhang zhouxiang zhang xuefei qi huarong zhao sanxue ren yang li 2017Journal of Meteorological Research2017,31,5:25
15Expenditure and financial burden for the diagnosis and treatment of colorectal cancer in China:a hospital.based,multicenter,cross-sectional survey显示文摘Background: The increasing prevalence of colorectal cancer(CRC) in China and the paucity of information about relevant expenditure highlight the necessity of better understanding the financial burden and effect of CRC diagnosis and treatment. We performed a survey to quantify the direct medical and non-medical expenditure as well as the resulting financial burden of CRC patients in China.Methods: We conducted a multicenter, cross-sectional survey in 37 tertiary hospitals in 13 provinces across China between 2012 and 2014. Each enrolled patient was interviewed using a structured questionnaire. All expenditure data were inflated to the 2014 Chinese Yuan(CNY; 1 CNY = 0.163 USD). We quantified the overall expenditure and financial burden and by subgroup(hospital type, age at diagnosis, sex, education, occupation, insurance type, household income, clinical stage, pathologic type, and therapeutic regimen). We then performed generalized linear modeling to determine the factors associated with overall expenditure.Results: A total of 2356 patients with a mean age of 57.4 years were included, 57.1 % of whom were men; 13.9% of patients had stage I cancer; and the average previous-year household income was 54,525 CNY.The overall average direct expenditure per patient was estimated to be 67,408 CNY, and the expenditures for stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ disease were 56,099 CNY, 59,952 CNY, 67,292 CNY, and 82,729 CNY, respectively. Non-medical expenditure accounted for 8.3%of the overall expenditure. The 1-year out-of-pocket expenditure of a newly diagnosed patient was 32,649 CNY, which accounted for 59.9% of their previous-year household income and caused 75.0% of families to suffer an unmanageable financial burden. Univariate analysis showed that financial burden and overall expenditure differed in almost all subgroups(P < 0.05), except for sex. Multivariate analysis showed that patients who were treated in specialized hospitals and those who were diagnosed with adenocarcinoma or diagnosed at a later stage were likely to spend more,whereas those with a lower household income and those who underwent surgery spent less(all P < 0.05).Conclusions: For patients in China, direct expenditure for the diagnosis and treatment of CRC seemed catastrophic,and non-medical expenditure was non-ignorable. The financial burden varied among subgroups, especially among patients with different clinical stages of disease, which suggests that, in China, CRC screening might be cost-effective.Hui-Yao Huang Ju-Fang Shi Lan-Wei Guo Ya-Na Bai Xian-Zhen Liao Guo-iangLiu A-Yan Mao Jian-Song Ren Xiao-Jie Sun Xin-Yu Zhu Le Wang Bing-Bing Song Ling-Bin Du Lin Zhu Ji-Yong Gong Qi Zhou Yu-Qin Liu Rong Cao Ling Mai Li Lan Xiao-Hua Sun Ying Ren Jin-Yi Zhou Yuan-Zheng Wang Xiao Qi Pei-An Lou Dian Shi Ni Li Kai Zhang Jie He Min Dai 2017Chinese Journal of Cancer2017,36,8:25
16Diagnosis and treatment of polypoid lesions of the gallbladder:report of 194 cases显示文摘BACKGROUND: With the wide use of B-ultrasonography in recent years, the polypoid lesion of the gallbladde ( PLG) has been one of the most common diseases detected in biliary surgery. This study was to investigate the diag nostic method and operative indications of PLG. METHODS: The clinical and pathological data of 194 pa tients with PLG who had received operation at our hospita from January 1994 to September 2002 were analyzed retro spectively. Categorized data were analyzed by the chi square test. RESULTS: All the patients received preoperative B-ultra- sonography. 185 of the 194 PLG patients were diagnosed as having cholecystic polyp, and 9 adenomas. Among the 42 patients who received CT, 6 showed early gallbladder can cer. Pathologically, cholesterol polyps were mostly multi ple lesions (64.7%) with a mean diameter of3.86±2.2 mm in 136 patients. Of 16 patients with adenomas, 10 had a tumor diameter of more than 10 mm (62.5%). In 11 pa tients with gallbladder carcinoma, 7 were accompanied with gallbladder stone (63.6%). In addition, inflammatory polyps and adenomyomas were found in 25 and 6 patients respectively. CONCLUSIONS: B-ultrasonography is the most effective diagnostic method for detecting PLG. When large or irreg- ular lesions are found, CT should be performed in order to avoid missing of gallbladder carcinoma. Operative indica- tions for PLG include; a maximal tumor diameter of more than 10 mm; an over 50-year-old patient with a wide-base and a single polyp lesion; a wide-base lesion or a lesion showing a tendency to enlargement; co-existing gallbladder stone or cholecystitis; a patient without other diseases but obvious clinical features and failure of general ma- nagement ; big or long pedicels or polyps at the neck of the gallbladder for preventing the empty of the gallbladder and a history of biliary colic; and PLG with irregularly thick- ened local gallbladder wall.Xue-Jun Sun, Jing-Sen Shi, Yue Han, Jian-Sheng Wang and Hong Ren Xi’ an, China Department of Surgery, First Hospital of Xi’ an Jiao- tong University, Xi’ an 710061 , China 2004Hepatobiliary & Pancreatic Diseases International2004,3,4:24
17Preliminary Scientific Results of Chang'E-1 Lunar Orbiter:Based on Payloads Detection Data in the First Phase显示文摘Chang'E-1 lunar Orbiter was launched by Long March 3A rocket from Xichang Satel-lite Launch Center at 18:05BT(Beijing Time) Oct.24,2007.It is the first step of its ambitious three-stage moon program,a new milestone in the Chinese space exploration history.The primary science objectives of Chang'E-1 lunar orbiter are to obtain three-Dimension(3D) stereo images of the lunar surface,to analyze the distribution and abundance of elements on the surface,to investigate the thickness of lunar soil,evaluate helium-3 resources and other characteristics,and to detect the space environment around the moon.To achieve the above four mission objectives,eight sets of scientific instruments are chosen as the payloads of the lunar orbiter,including a CCD stereo camera(CCD),a Sagnac-based interferometer spectrometer(ⅡM),a Laser Altimeter(LAM),a Microwave Radiometer(MRM),a Gamma-Ray Spectrometer(GRS),an X-ray spectrometer(XRS),a High-Energy Particle Detector(HPD),and two Solar Wind Ion Detectors(SWID).The detected data of the payloads show that all payloads work well.This paper introduces the status of payloads in the first phase and preliminary scientific results.OUYANG Ziyuan JIANG Jingshan LI Chunlai SUN Huixian ZOU Yongliao LIU Jianzhong LIU Jianjun ZHAO Baochang REN Xin YANG Jianfeng ZHANG Wenxi WANG Jianyu MOU Lingli CHANG Jin ZHANG Liyan WANG Huanyu LI Yongquan ZHANG Xiaohui ZHENG Yongchun WANG Shijin BIAN Wei 2008空间科学学报2008,28,5:24
