Significance of Golgi Protein 73, Alpha-Fetoprotein and Vascular Endothelial Growth Factor Expression in Diagnosis of Primary Hepatic Cancer  [PDF]
Xinfeng Li, Xiaofu Li, Wenrui Zhou, Gaoxiong Wang, Wei Wang
Journal of Cancer Therapy (JCT) , 2015, DOI: 10.4236/jct.2015.613124
Abstract: Aim: We measured Golgi protein73 (GP73), alpha-fetoprotein (AFP), and vascular endothelial growth factor (VEGF) expression in primary hepatic cancer (PHC) and assessed their clinical significance. Methods: Forty-five PHC and tumor-adjacent specimens and 14 normal liver specimens were examined. GP73, AFP, and VEGF expression was measured via immunohistochemistry and a correlation of protein expression with clinical pathology of PHC was suggested. Results: GP73, AFP, and VEGF expression was significantly higher in PHC and tumor-adjacent tissue compared to tumor-adjacent tissue (0.143 ± 0.018 vs. 0.124 ± 0.027, 0.116 ± 0.026 vs. 0.098 ± 0.014, and 0.126 ± 0.027 vs. 0.092 ± 0.016, respectively; all p < 0.05) and normal liver tissue (0.124 ± 0.027 vs. 0.088 ± 0.029, 0.098 ± 0.014 vs. 0.073 ± 0.011, and 0.092 ± 0.016 vs. 0.076 ± 0.018, respectively; all p < 0.05), respectively. GP73 expression was positively correlated with pathological grade and cirrhosis, but not with tumor size, nodules, clinical stage and serum AFP. VEGF expression was positively correlated with tumor size, nodules, portal vein tumor thrombus, and clinical stage, but not with the degree of tumor differentiation and serum AFP. Expression of GP73 and VEGF was greater than that of AFP in PHC (both p < 0.05). Conclusion: GP73 is highly expressed in PHC and may be a diagnostic marker. Combined detection of GP73, AFP, and VEGF is helpful for diagnosis of PHC.

Open Journal of Epidemiology (OJEpi) , 2014, DOI: 10.4236/ojepi.2014.43019
Abstract:

Background: The aim of this study was to explore the characteristics of breast cancer mortality in Inner Mongolia, and to provide evidence for the prevention of female breast cancer. Methods: Using data from the Death Registry System from 2008 to 2010. We classified female cancer deaths according to the International Classification of Disease-10th Revision. The mortality of different age groups and the potential years of life lost were calculated for female breast cancer in Inner Mongolia. Results: Breast cancer mortality for Inner Mongolian women was higher in older age groups. The potential years of life lost were also much higher in younger groups than in older groups. Marital status, education level and occupation may contribute to this increase in breast cancer mortality in younger groups. Conclusion: Preventive policies should be implemented to de- velop strategies aimed at reducing the breast cancer mortality, especially with regard to younger age groups in Inner Mongolia.

An analysis of the spatial and temporal changes in Chinese terrestrial ecosystem service functions
Yao Shi,RuSong Wang,JinLou Huang,WenRui Yang
Chinese Science Bulletin , 2012, DOI: 10.1007/s11434-012-4978-5
Abstract: Since Westman (1977) and Ehrlich (1982) put forward the concepts of “the service of nature” and “ecosystem service functions”, respectively, methods for conducting value accounting for them, and their practical application have become the subjects of intense study. Based on an overview of available research findings, we discuss three scientific hypotheses. First, the terrestrial ecosystem offers both positive and negative service functions. Second, changes in terrestrial ecosystem service functions lie not only in the number of ecosystem types and the coverage area of each type, but also in their quality. Third, the value of terrestrial ecosystem service functions should be assessed both in terms of the value stocked and the value added. We collected land use data from China during the period 1999–2008, and Normalized Difference Vegetation Index data based on remote sensing images from the Global Inventory Modeling and Mapping Studies for the same period. We then calculated and analyzed spatial and temporal changes in China’s terrestrial ecosystem service values over the 10-year period. Considering temporal change, the total value (stocked) of China’s terrestrial ecosystem service functions decreased from 6.82 trillion Yuan RMB in 1999 to 6.57 trillion Yuan RMB in 2008. During that period, the positive value decreased by 240.17 billion Yuan RMB and the negative value increased by 8.85 billion Yuan RMB. The decrease in total value lies mainly in the humidity control, soil formation, and waste recycling functions. The total value (added) of China’s terrestrial ecosystem service functions increased by 4.31 billion Yuan RMB in 2000, but decreased by 0.13 billion Yuan RMB in 2008 (based on the constant price of China in 1999). The value (added) was a negative figure. From the perspective of spatial change, we can see that the supply of China’s terrestrial ecosystem service functions fell slightly over the past 10 years, mainly in Northeast and Southern China. As a result of human activities on ecosystems, the loss of ecosystem service functions’ value was relatively prominent in Shanxi and Gansu provinces, compared with an increase in value in Shaanxi Province. Terrestrial ecosystem service functions’ value per unit area was relatively high in mid- and East China, showing a prominent spatial change over the 10-year period, but low in Western China. Some conclusions are drawn after an in-depth analysis of the factors causing the spatial and temporal changes in China’s terrestrial ecosystem service functions, in the hope that our suggestions will be helpful for the management of China’s terrestrial ecosystems.

Abstract: A pot experiment was conducted to evaluate the bioaccumulation of heavy metals and growth response of rice plants after exposure to single and combined contamination by Cu, Cd and Pb. The results showed that the biomass production was not significantly affected by either single or combined treatment of Cu, Cd and Pb. Adding Cu (Cd, or Pb) separately all increased concentrations of the respective element in root and shoot (p < 0.001). In the combined contamination, Pb promoted both root and shoot absorption of Cu and Cd (p < 0.001), and Cu affected Cd and Pb absorption in the root, but Pb concentrations in both root and shoot were not affected by Cd application. The formation of iron plaques varied obviously with soil types. Heavy metal accumulation in iron plaques was induced by the three elements (p < 0.001). Furthermore, the three heavy metals exhibited an interactive relationship as measured by the Cu, Cd, Pb and Fe concentrations in root surface iron plaques. The iron plaques partially inhibited transfer of Pb to root and shoot, but no such effect was observed for Cu and Cd. This research indicates that the interaction among different heavy metal elements is very complex. It is very important to have a clear understanding on the associated mechanism and the consequential impact on plant growth.

Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810016995
Abstract: In the title compound, [Cr2Ni(C16H14N2O2)2(CN)4(C10H24N4)]·2CH3OH, each [Cr(salen)(CN)2] unit {salen is 2,2′-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolate} acts as a monodentate ligand through one of its two cyanide groups N bound to a central [Ni(cyclam)]2+ core (cyclam is 1,4,8,11-tetraazacyclotetradecane). Each CrIII ion is coordinated by two N and two O atoms from a salen ligand situated in the equatorial plane with two trans cyanide C atoms, yielding a distorted octahedral coordination geometry. The NiII atom lies on an inversion center and is octahedrally coordinated by a cyclam ligand lying in the equatorial plane and by two cyanide N atoms. The asymmetric unit contains one half of the complex molecule and a methanol solvent molecule. In the crystal structure, the complex molecule is linked to the methanol solvent molecules via O—H...O and N—H...O hydrogen bonds. Individual complex molecules are linked by C—H...N hydrogen bonds, forming chains along b.

Abstract: A field survey was conducted in a contaminated industrial site in southern Beijing, China to investigate theconcentrations and distribution of the organochlorine pesticides (α-, β-, γ-, δ-HCH, p,p'-DDT, p,p'-DDE, p,p'-DDD and o,p'-DDT) in the profiles of soil, and a health risk assessment was carried out with CalTOX multimedia exposure model. Results showed that mean concentrations of total hexachlorocyclohexane isomers (HCHs) and total dichlorodiphenyltrichloroethane isomers (DDXs) in soils ranged in 13.19-148.71 mg/kg, and 3.02-67.42 mg/kg, respectively. Organochlorine pesticides (OCPs) concentration peaked at the surface and declined in soil profile with depth and the amounts of HCHs in three profiles of soil were larger than DDXs. Composition analysis indicated that there was a trend of degradation of OCPs in the site, but the mean of HCHs and DDXs concentration were over the state warning standard limit (HCHs, 0.50 mg/kg; DDXs, 0.50 mg/kg). According to current land use development, health risk assessment with CalTOX and Monte Carlo analysis showed that health risks mainly came from two exposure pathways: dermal uptake and inhalation, and that the total risk values all exceeded the general acceptable health risk value (10-6). The sensitivity analysis indicated that five parameters significantly contributed to total risk.
High-precision Absolute Distance Measurements over a Long Range Based on Two Optoelectronic Oscillators

Physics , 2012,
Abstract: Absolute distance measurement (ADM) over a long range has been studied intensely over the last several decades, due to its important applications in large-scale manufacturing and outer space explorations [1-5]. Traditional absolute distance measurements utilize detection of time-of-flight information, detection of phase shift, or a combination of the two [6-17]. In this paper, we present a novel scheme for high-precision ADM over a long range based on frequency detection by using two optoelectronic oscillators (OEO) to convert distance information to frequency information. By taking advantage of accumulative magnification theory, the absolute error of the measured distance is magnified by about 2*10E5 times, which makes the precision of the measured distance significantly improved. In our experiments, the maximum error is 1.5 um at the emulated ~6 km distance, including the drift error of about 1 um in the air path due to the change in environmental conditions. In addition, the measurable distance using this scheme could be further extended. The highest relative measurement precision is 2*10E10 in our current system while the actual relative measurement precision of our experimental system is limited by the variation of atmospheric conditions and is about 4*10E9.
