| 5 | The Relationship between Jurassic Coal Measures and Sandstone-type Uranium Deposits in the Northeastern Ordos Basin,China显示文摘Outcrop and drill hole data show that the Jurassic coal measures in the northeastern Ordos Basin are composed mainly of the Yan'an Formation and the lowstand system tract of the Zhiluo Formation,and there is a regional unconformity between them. The Dongsheng uranium deposit is associated with the Jurassic coal measures. Research data indicate that the Jurassic coal measures in the study area have a certain hydrocarbon-generating capacity,although the metamorphic grade is low(Ro=0.40%–0.58%). In the Dongsheng region alone,the accumulative amount of generated coalbed methane(CBM) is about 2028.29 × 108 –2218.72 × 108 m^3; the residual amount is about 50.92 × 108 m^3,and the lost amount is about 1977 × 108 m^3. Analysis of the burial history of the host rocks and the evolutionary history of the Dongsheng uranium deposit suggests that the Jurassic coal measures generated hydrocarbon mainly from Middle Jurassic to Early Crataceous,which is the main mineralization phase of the Dongsheng uranium deposit. By the Late Cretaceous,a mass of CBM dissipated due to the strong tectonic uplift,and the Dongsheng uranium deposit stepped into the preservation phase. Therefore,the low-mature hydrocarbon-containing fluid in the Jurassic coal measures not only served as a reducing agent for the formation of sandstone-type uranium deposits,but also rendered the second reduction of paleo-interlayer oxidation zone and become the primary reducing agent for ore conservation. Regional strata correlation reveals that the sandstone-type uranium reservoir at the bottom of the Zhiluo Formation is in contact with the underlying industrial coal seams in the Yan'an Formation through incision or in the form of an unconformity surface. In the Dongsheng region with poorly developed fault systems,the unconformity surface and scour surface served as the main migration pathways for low-mature hydrocarbon-containing fluid migrating to the uranium reservoir. | JIAO Yangquan WU Liqun RONG Hui PENG Yunbiao MIAO Aisheng WANG Xiaoming | 2016 | Acta Geologica Sinica(English Edition)2016，90，6： | 24 |
| 6 | Study on Relationship between Microstructure of Active Phase and HDS Performance of Sulfided Ni-Mo Catalysts: Effect of Metal Loading显示文摘Six Ni-Mo catalysts with different metal contents were prepared and characterized by N2 adsorption and X-ray diffractometry. The active phase microstructure of these catalysts was examined by the Raman spectroscopy, temperatureprogrammed reduction(TPR), X-ray photoelectron spectroscopy, and high-resolution transmission electron microscopy. Hydrodesulfurization(HDS) activity of catalyst samples were analyzed in a flow fixed-bed microreactor. The sulfidation degree of Mo and the length of the MoS2 slab slightly increased with the amount of metal loaded following sulfidation. This small change is attributed to polymolybdate species observed in all the oxidized catalysts. Weak metal-support interactions, as determined by the TPR technique, increased the NiSx sulfidation phase and MoS2 slab stacking. The HDS activity of the catalyst samples increased with the number of active sites. For high metal loading catalysts, their HDS activity was nearly identical because the sulfur atoms cannot easily approach active sites. This change is caused by the large number of stacked layers in the MoS2 slabs as well as the decrease in the specific surface area and pore volume of the catalyst samples with an increasing metal loading. | Guo Rong Shen Benxian Fang Xiangchen Sun Jin Peng Chong Cui Xiaoli | 2014 | China Petroleum Processing & Petrochemical Technology2014，16，2： | 21 |
| 7 | BMI, WC, WHtR, VFI and BFI: Which Indictor is the Most Efficient Screening Index on Type 2 Diabetes in Chinese Community Population显示文摘Objective Obesity is a major risk factor for type 2 diabetes, many indexes can be used to describes obesity and predict diabetes. This research attempts to identify the best indicator of obesity to screening diabetes in Chinese population. Methods A cross-sectional data of 8121 subjects aged 35-60 years were included in this research belongs to the Diabetes Appropriate Technology Intervention Study. Anthropometric indicators including body weight, height, waist circumferences (WC), body fat index (BFI) and visceral fat index (VFI) and blood biochemical indicators after an overnight fast [fasting blood glucose, total cholesterol, high-density lipoprotein (HDL) cholesterol, and triacylglycerol] were measured. BMI (body mass index) and Weight to Height Ratio was calculated. Results Subjects with obesity had a higher risk of physician diagnosed diabetes (OR=2.50, 95% CI 1.83-3.43), new diagnosed diabetes (OR=4.23, 95% CI 2.91-6.15) and pre-diabetes (OR=1.75, 95% CI 1.31-2.34) compared to those with normal Body mass index (BMI). There was a significant trend of increased risk of all diabetes status with increased waist circumference (WC). The waist-to-height ratio (WHtR) yielded the most significant association with new diagnosed diabetes and physician diagnosed diabetes than other indices. Conclusion Central obesity is significantly correlated with diabetes. VFI was most correlated with pre-diabetes while WHtR is an efficient screening index than BMI and WC in Chinese community diabetes screening. | MI Sheng Quan YIN Peng HU Nan LI Jian Hong CHEN Xiao Rong CHEN Bo YAN Liu Xia ZHAO Wen Hua | 2013 | Biomedical and Environmental Sciences2013，26，6： | 20 |

| 12 | 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 |

| 14 | Gearbox Fault Diagnosis using Adaptive Zero Phase Time-varying Filter Based on Multi-scale Chirplet Sparse Signal Decomposition显示文摘When used for separating multi-component non-stationary signals, the adaptive time-varying filter(ATF) based on multi-scale chirplet sparse signal decomposition(MCSSD) generates phase shift and signal distortion. To overcome this drawback, the zero phase filter is introduced to the mentioned filter, and a fault diagnosis method for speed-changing gearbox is proposed. Firstly, the gear meshing frequency of each gearbox is estimated by chirplet path pursuit. Then, according to the estimated gear meshing frequencies, an adaptive zero phase time-varying filter(AZPTF) is designed to filter the original signal. Finally, the basis for fault diagnosis is acquired by the envelope order analysis to the filtered signal. The signal consisting of two time-varying amplitude modulation and frequency modulation(AM-FM) signals is respectively analyzed by ATF and AZPTF based on MCSSD. The simulation results show the variances between the original signals and the filtered signals yielded by AZPTF based on MCSSD are 13.67 and 41.14, which are far less than variances (323.45 and 482.86) between the original signals and the filtered signals obtained by ATF based on MCSSD. The experiment results on the vibration signals of gearboxes indicate that the vibration signals of the two speed-changing gearboxes installed on one foundation bed can be separated by AZPTF effectively. Based on the demodulation information of the vibration signal of each gearbox, the fault diagnosis can be implemented. Both simulation and experiment examples prove that the proposed filter can extract a mono-component time-varying AM-FM signal from the multi-component time-varying AM-FM signal without distortion. | WU Chunyan LIU Jian PENG Fuqiang YU Dejie LI Rong | 2013 | Chinese Journal of Mechanical Engineering2013，26，4： | 16 |
| 15 | Developmental Genetics Analysis for Plant Height in indica Hybrid Rice Across Environments显示文摘The developmental genetics of plant height was analyzed from two groups of three-line indica hybrid rice at two environmental conditions based on the NCII design,using the additive-dominant developmental genetics models and the statistic methods.The results showed that the rice genotypes and environmental conditions could both affect plant height,and the effects of environment on plant height decreased gradually with plant development.Additive and dominant effects both governed the performance of plant height at all developmental stages.However,the degrees of effect varied among the rice genotypes.Moreover,the interaction between environments and genotypes also affected plant height.The genetic effects differed at most developmental stages.Furthermore,the expression of additive effect was more active than that of dominant effect.Conditional interaction effects with environment also influenced plant height during genetic development,especially at the early stage.Mid-parent heterosis(HMP) increased gradually with the developmental stage of plant height,and maximized at the latest stage,whereas the heterosis over the better parent(HBP) showed small differences among the genotypes,and kept stable at the later stage,with positive numeric value.At most developmental stages,conditional HMP was positively significant,while conditional HBP was negatively significant.All above results suggest that HMP and HBP have some new expressions in all developmental periods and the levels and directions are quite different. | PENG Tao ZHONG Bing-qiang LING Ying-hua YANG Zheng-lin ZHA Ren-ming XIE Rong LIU Cheng-yuan HE Guang-hua | 2009 | Rice science2009，16，2： | 14 |

| 18 | Analysis of bacterial community in bulking sludge using culture-dependent and -independent approaches显示文摘The bacterial community of a bulking sludge from a municipal wastewater treatment plant with anoxic-anaerobic-oxic process was investigated by combination of cultivation and 16S rRNA gene clone library analysis for understanding the causes of bulking.A total of 28 species were obtained from 63 isolates collected from six culture media.The most cultivable species belonged to γ-Proteobacteria including Klebsiella sp.,Pseudomonas sp.,Aeromonas sp.and Acinetobacter sp.Further analysis of these strains by repetitive sequence based on polymerase chain reaction (rep-PCR) technology showed that rep-PCR yielded discriminatory banding patterns within the same genus using REP and BOX primer sets.While the culture-independent assessment revealed that β-Proteobacteria was the dominant group in the bulking sample.Sequence analysis revealed that the highest proportion (14.7%) of operational taxonomic units was 98% similar to Candidatus Accumulibacter phosphatis,which is used to remove phosphorous from wastewater.Our results indicated that combining different approaches can produce complementary information,thus generate a more accurate view of microbial community in bulking sludge. | Decai Jin Ping Wang Zhihui Bai Xinxin Wang Hong Peng Rong Qi Zhisheng Yu Guoqiang Zhuang | 2011 | Journal of Environmental Sciences2011，23，11： | 11 |

| 20 | A recessive gene controlling male sterility sensitive to short daylength/low temperature in wheat(Triticum aestivum L.)显示文摘Utilization of a two-line breeding system via photoperiod-thermo sensitive male sterility has a great potential for hybrid production in wheat(Triticum aestivum L.).337S is a novel wheat male sterile line sensitive to both short daylength/low temperature and long daylength/high temperature.Five F2 populations derived from the crosses between 337S and five common wheat varieties were developed for genetic analysis.All F1's were highly fertile while segregation occurred in the F2 populations with a ratio of 3 fertile:1 sterile under short daylength/low temperature.It is shown that male sterility in 337S was controlled by a single recessive gene,temporarily designated as wptms3.Bulked segregant analysis(BSA) coupled with simple sequence repeat(SSR) markers was applied to map the sterile gene using one mapping population.The wptms3 gene was mapped to chromosome arm 1BS and flanked by Xgwm413 and Xgwm182 at a genetic distance of 3.2 and 23.5 cM,respectively.The accuracy and efficiency of marker-assisted selection were evaluated and proved essential for identifying homozygous recessive male sterile genotypes of the wptms3 gene in F2 generation. | Xiao-dong CHEN Dong-fa SUN De-fu RONG Jun-hua PENG Cheng-dao LI | 2011 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2011，12，11： | 10 |
