| 1 | Expression of calreticulin is associated with infiltration of T-cells in stage ⅢB colon cancer显示文摘AIM: To investigate the correlation between expression of calreticulin and infiltration of lymphocytes in stage ⅢB colon cancer. METHODS: Sixty-eight pathologically-confirmed speci-mens were obtained from stage ⅢB (T3N1M0) colon cancer patients who underwent radical resection between January 1999 and May 2002 at the Cancer Center of Sun Yat-Sen University, Guangzhou, China. Immuno-histochemical analysis was performed to show infiltration of lymphocytes and expression of calreticulin in colon cancer. Association between calreticulin expression, infiltration of lymphocytes, and 5-year survival rate of patients was assessed. RESULTS: The expression level of calreticulin was lower in cancer nest than in its adjacent normal epithelium since 61.8% (42/68) of the samples were stained with calreticulin in colon cancer. The expression of calreticulin in colon cancer was associated with the infi ltration of CD45RO+ cells rather than with that of CD3+ cells. In addition, the stronger expression of calreticulin and the higher infiltration of CD3+ and CD45RO+ cells in colon cancer were associated with the higher 5-year survival rate of patients. CONCLUSION: Expression of calreticulin is associated with infiltration of T-cells, which implies that a low expression level of molecular marker may represent a new mechanism underlying immune escape in colon cancer. | Rui-Qing Peng, Ya Ding, Xing Zhang, Yi-Xin Zeng, Xiao- Shi Zhang, State Key Laboratory of Oncology in South China, Biotherapy Center, Cancer Center, Sun Yat-Sen University, 651 Dongfeng R E, Guangzhou 510060, Guangdong Province, China Ying-Bo Chen, Zhi-Wei Zhou, State Key Laboratory of Oncology in South China, Department of Gastric and Pancreatic Oncology, Cancer Center, Sun Yat-Sen University, 651 Dongfeng R E, Guangzhou 510060, Guangdong Province, China Rong Zhang, State Key Laboratory of Oncology in South China, Department of Endoscopy, Cancer Center, Sun Yat-Sen University, 651 Dongfeng R E, Guangzhou 510060, Guangdong Province, China Xing-Juan Yu, Yi-Xin Zeng, State Key Laboratory of Oncology in South China, Department of Experimental Research, Cancer Center, Sun Yat-Sen University, 651 Dongfeng R E, Guangzhou 510060, Guangdong Province, China | 2010 | World Journal of Gastroenterology2010，16，19： | 16 |
| 2 | Caveolin-1 gene silencing promotes the activation of PI3K/AKT dependent on Erα36 and the transformation of MCF10A^(CE)显示文摘ERα36,a variant of estrogen receptor-α,acts as a dominant-negative factor in both estrogen-dependent and estrogen-independent transactivation signaling pathways,and is a key factor in the promotion,progression and prognosis of breast cancers.Caveolin-1,a 22-to 24-kD integral membrane protein,may function as a tumor suppressor in inhibiting of many growth-promoting signaling pathways.It was shown that downregulation of Caveolin-1 strengthens the interaction of ERα and Caveolin-1.In conclusion,Caveolin-1 gene silencing activated the PI3K/AKT signaling pathway in an ERα36-dependent way.Our finding may provide a promising therapeutic target of breast cancer. | FENG Shuang1,WANG Yang1,WANG Xi1,WANG ZhaoYi3,CUI YuYing1,LIU Jing4,ZHAO ChunHui1,JIN Mei1,2 & ZOU Wei1,2 1 College of Life Science,Liaoning Normal University,Dalian 116029,China 2 Liaoning Key Laboratory of Biotechnology and Molecular Drug R&D,Dalian 116029,China 3 Cancer Center,Creighton University,2500 California Plaza,Omaha,NE 68178,USA 4 First Clinical Hospital of Dalian Medical University,Dalian 116011,China | 2010 | Science China(Life Sciences)2010，53，5： | 16 |
| 3 | The Red Edge Parameters of Different Wheat Varieties Under Different Fertilization and Irrigation Treatments显示文摘The dynamics of red edge parameters at different growth stages of wheat canopy was studied.The red edge position moved to the longer wavelength from erecting stage to heading stage, and returned to the original wavelength direction from grain-filling stage to maturity stage. The leaf total nitrogen content (LTN)is positively related to red edge amplitude (d λ red) and NIR platform amplitude (d λNIRP) and the correlation coefficient improved as growth stage extended. The chlorophyll content (TChl) is negatively related to d λ red from erecting stage to the elongation stage, and positively related to d λ red from heading stage to milky maturity stage. TChl is also positively related to d λNIRP. The leaf area index (LAI) is positively related to d λ red and d λNIRP, and the correlation coefficient improved as growth stage extended. It was concluded that d λ red and d λNIRP can be used as the indicators of winter wheat growth state, and guide the fertilization and irrigation decision making. The λNIRP is suitable for derivation of LTN, the d λ red for TChl, and the d λ red or d λNIRP for LAI. | ZHAO Chun-Jiang, HUANG Wen-Jiang, WANG Ji-hua, YANG Min-hua and XUE Xu-zhang( National Engineering Center for Information Technology in Agriculture , Beijing 100089 , P.

| 8 | Enhancing disease resistances of Super Hybrid Rice with four antifungal genes显示文摘A plant expression vector harboring four antifungal genes was delivered into the embryogenic calli of ‘9311’, an indica restorer line of Super Hybrid Rice, via modified biolistic particle bombardment. Southern blot analysis indicated that in the regenerated hygromycin-resistant plants, all the four anti-fungal genes, including RCH10, RAC22, β-Glu and B-RIP, were integrated into the genome of ‘9311’, co-transmitted altogether with the marker gene hpt in a Mendelian pattern. Some transgenic R1 and R2 progenies, with all transgenes displaying a normal expression level in the Northern blot analysis, showed high resistance to Magnaporthe grisea when tested in the typical blast nurseries located in Yanxi and Sanya respectively. Furthermore, transgenic F1 plants, resulting from a cross of R2 homo-zygous lines with high resistance to rice blast with the non-transgenic male sterile line Peiai 64S, showed not only high resistance to M. grisea but also enhanced resistance to rice false smut (a disease caused by Ustilaginoidea virens) and rice kernel smut (another disease caused by Tilletia barclayana). | ZHU HuaChen1, XU XinPing1, XIAO GuoYing2,3, YUAN LongPing2 & LI BaoJian1 1 Biotechnology Research Center, Key Laboratory of Gene Engineering of Ministry of Education, Sun Yat-sen University, Guangzhou 510275, China 2 China National Hybrid Rice R&D Center, Hunan Hybrid Rice Research Center, Changsha 410125, China 3 Institute of Subtropical Agriculture, the Chinese Academy of Sciences, Changsha 410125, China | 2007 | Science China(Life Sciences)2007，50，1： | 6 |
| 9 | Preliminary discussion of low-salinity hydrothermal fluid mineralization显示文摘REVIEWING the history of the geology of mineral deposits, we may find that in the first fifty years of thetwentieth century the magmatic-hydrothermal theory of ore deposition was the most prevalent, whichgave impetus to the development of the geology of mineral deposits. In the 1960s, the drilling of theSalton Sea geothermal field, California, the United States, and discovery and study of the Red Sea seafloor hot brines and large amounts of metal sulfides removed therefrom led to the rise of the brine theory ofmineral deposition, thus elucidating the origin of massive metal sulfides and promoted the discoveryand exploration of metal deposits. After the 1970s and the 1980s, through a study of the hydrothermal ore fluids of modern hotsprings. geologists came to realize that there exist low-salinity hydrothermal ore fluids other than | ZHENG Mianping R & D Center of Saline Lake and Epithermal Deposits, Chinese Academy of Geological Sciences, Beijing 100037, China | 1999 | Chinese Science Bulletin1999，44，S2： | 5 |
| 10 | The Machine Recognition for Population Feature of Wheat Images Based on BP Neural Network显示文摘Recognition and analysis of dynamic information about population images during wheat growth periods can be taken for the base of quantitative diagnosis for wheat growth. A recognition system based on self-learning BP neural network for feature data of wheat population images, such as total green areas and leaves areas was designed in this paper. In addition, some techniques to create favorable conditions for image recognition was discussed, which were as follows: (1) The method of collecting images by a digital camera and assistant equipment under natural conditions in fields. (2) An algorithm of pixei labeling was used to segment image and extract feature. (3)A high pass filter based on Laplacian was used to strengthen image information. The results showed that the ANN system was availability for image recognition of wheat population feature. | LI Shao-kun, SUO Xing-mei, BAI Zhong-ying, QI Zhi-li, Liu Xiao-hong, GAO Shi-ju and ZHAO Shuang-ning( Institute of Crop Breeding and Cultivation /Key Laboratory of Crop Genetic & Breeding, Ministry of Agriculture, ChineseAcademy of Agricultural Sciences, Beijing 100081 , P .

| 12 | The influence of impurity on the critical thickness of the CeO_2 buffer layer for coated conductors显示文摘The lattice parameters, band structure, density of state and elastic constant of RE-doped CeO2 (RE=Sm, Gd, Dy), the buffer material for coated HTS conductors, are calculated using the plane-wave method with pseudopotentials based on the density functional theory (DFT) of first-principle. The rule and mechanism of the effect of rare earth impurity on the critical thickness of the CeO2 buffer layer are investigated. It is found that, in the range of the calculation, the changes of the lattice volume V and elastic constant E of CeO2 with the impurity are mainly determined by the increased electrons ne of the system. The relationship of the elastic constant E and increased electrons ne is established. It is indicated that the critical thickness of the CeO2 single buffer layer doped with Sm, Gd, and Dy may be enhanced by 22%, 43% and 33%, respectively. | PAN Min1, HUANG Zheng2, MA HuanFeng2, QIANG WeiRong2, WEI LianFu1, WANG Long2 & ZHAO Yong1,3 1 Key Laboratory of Magnetic Levitation Technologies and Maglev Trains (Ministry of Education of China), Superconductivity R&D Center (SRDC), Southwest Jiaotong University, Chengdu 610031, China 2 School of Physical Science and Technology, Southwest Jiaotong University, Chengdu 610031, China 3 Superconductivity Research Group, School of Materials Science and Engineering, University of New South Wale, Sydney, 2052 NSW, Australia | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，7： | 3 |
| 13 | The effects of K^+ growth conditions on the accumulation of cesium by the bacterium Thermus sp. TibetanG6显示文摘The accumulation of cesium by the bacterium Thermus sp. TibetanG6 was examined under different K+ growth conditions. The effects of external pH and Na+ on the accumulation of ce-sium were also studied, and the mechanism involved was discussed. K+ regimes played an important role in the accumulation of cesium by the strain TibetanG6. The quantity of cesium accumulated (24 h) was much higher in K+-deficient regime than that in K+-sufficient regime. The pH and Na+ had different effects on the accumulation of cesium in the two K+ regimes. IR spectra analyses indicated that the biosorption is a process of homeostasis with cesium initially accumulated on the cell wall. | WANG Hailei1,2,3, KONG Fanjing1,2,3 & ZHENG Mianping1,2,3 1.

| 14 | Development of Temperature-Humidity Independent Control Air-Conditioning Unit for Residential Buildings显示文摘Cooling panels are increasingly used in domestic residential buildings.To provide medium temperature cold water for the cooling panel,and dehumidify the indoor air simultaneously,a new kind of temperature-humidity independent control air-conditioning unit was developed for single residential house by utilizing multi-variable technology.First,the supply air temperature was studied to determine the proper supply air flow rate for the humidity control.Then,the energy consumption of different temperature-humidity independent control systems was studied.The analysis indicates that unity evaporating temperature can be used to handle the moisture load and sensible heat load in two evaporators.So the unit scheme was put forward.Two evaporators were used to produce medium temperature water and dry air separately,and electric expansion valves were used to control the refrigerant distribution between the two evaporators.Then,experimental work was carried out to investigate the influence of compressor frequency,refrigerant distribution on the dehumidification capacity,energy efficiency and refrigeration capacity.In the end,the paper concludes that both compressor frequency and refrigerant distribution can control the dehumidification capacity,but the former influences the EER more than the latter,while the latter influences the refrigeration capacity more than the former.We can find a proper running point at certain sensible and latent cooling load by adjusting both compressor frequency and electric expansion valve.The energy consumption of this kind of unit was estimated and compared with present room air conditioners,which shows that it can save about 41% cooling energy consumption. | HAN Xing1,ZHANG Xu1,LIU Jin-tao2,GAO Si-yun2,KANG Yue2(1.Institute of HVAC & Gas,College of Mechanical Engineering,Tongji University,Shanghai 200092,China 2.Hisense R&D Center,Qingdao,266000,China) | 2009 | 湖南大学学报(自然科学版)2009，36，S1： | 3 |

| 20 | Cesium accumulation by bacterium Thermus sp. TibetanG7:hints for biomineralization of cesium-bearing geyserite in hot springs in Tibet,China显示文摘The bacterium Thermus sp. TibetanG7, isolated from hot springs in Tibet, China, was examined for the ability to accumulate cesium from solutions. Environmental conditions were simulated and the effects of pH, K+, Na+ and K+-regimes were then studied to determine the possible role of the bacterium in the formation of cesium-bearing geyserite around these hot springs. In despite of the inhibition of K+ and Na+, the bacterium Thermus sp. TibetanG7 revealed noticeable accumulation of cesium from solutions, with maximum accumulations of 53.49 and 40.41 μmol Cesium/g cell dry weight in Na+ and K+ inhibition experiments, respectively. The accumulation of cesium by this microorganism is rapid, with 40%―50% accumulated within the first 5 min. K+-deficient cells showed a much higher capacity of cesium accu- mulation compared with K+-sufficient cells. It is evident that the bacteria within the genus thermus play a significant role in the cesium assembly. The formation of cesium-bearing geyserite is also considered. | WANG HaiLei1,2,3, ZHENG MianPing1,2,3 & HUANG XiaoXing4 1 Institute of Mineral Resources, Chinese Academy of Geological Sciences (CAGS), Beijing 100037, China 2 R&D Center for Saline Lake and Epithermal Deposits, CAGS, Beijing 100037, China 3 Open Laboratory of Saline Lake Resourses and Environment, CAGS, Beijing 100037, China 4 Laboratory of Microbial Resources, Institute of Microbiology, Chinese Academy of Sciences, Beijing 100081, China | 2007 | Chinese Science Bulletin2007，52，19： | 2 |
