| 1 | Investigation of the characteristics and deactivation of catalytic active center of Cr-Al_2O_3 catalysts for isobutane dehydrogenation显示文摘Deactivation mechanism of Cr-Al2O3 catalyst and the interaction of Cr-Al in the dehydrogenation of isobutane, as well as the nature of the catalytic active center, were studied using XRD, SEM, XPS, H2-TPR, isobutane-TPR and TPO techniques. The results revealed that the deactivation of Cr-Al2O3 catalyst was mainly caused by carbon deposition on its surface. The Cr3+ion could not be reduced by hydrogen but could be reduced to Cr2+by hydrocarbons and monoxide carbon. The active center for isobutane dehydrogenation could be Cr2+/Cr3+produced from Cr6+by the on line reduction of hydrocarbon and carbon monoxide. The binding energy of Al3+was strongly affected by the state of chromium cations in the catalysts. | Deren Fang Jinbo Zhao Wanjun Li Xu Fang Xin Yang Wanzhong Ren Huimin Zhang | 2015 | Journal of Energy Chemistry2015，24，1： | 8 |
| 2 | Interaction Between Variations in Dopamine D2 and Serotonin 2A Receptor is Associated with Short-Term Response to Antipsychotics in Schizophrenia显示文摘Dear Editor,Schizophrenia is a chronic and debilitating brain disorder,which has a strong genetic component with heritability ranging from 66%to 85%[1,2].Currently,antipsychotic drugs remain the most effective treatment for the psychotic symptoms of schizophrenia[3].Because of the severe sideeffects of first-generation antipsychotics(FGAs),secondgeneration antipsychotics(SGAs)have become more widely used in the treatment of schizophrenia. | Liansheng Zhao Huijuan Wang Yamin Zhang Jinxue Wei Peiyan Ni Hongyan Ren Gang Li Qiang Wang Gavin P Reynolds Weihua Yue Wei Deng Hao Yan Liwen Tan Qi Chen Guigang Yang Tianlan Lu Lifang Wang Fuquan Zhang Jianli Yang Keqing Li Luxian Lv Qingrong Tan Yinfei Li Hua Yu Hongyan Zhang Xin Ma Fude Yang Lingjiang Li Chuanyue Wang Huiyao Wang Xiaojing Li Wanjun Guo Xun Hu Yang Tian Xiaohong Ma Jeremy Coid Dai Zhang Chao Chen Tao Li Chinese Antipsychotics Pharmacogenomics Consortium | 2019 | Neuroscience Bulletin2019，35，6： | 3 |
| 3 | Testing the role of genetic variation of the MC4R gene in Chinese population in antipsychotic-induced metabolic disturbance显示文摘Antipsychotic-induced metabolic disturbance(AIMD) is a common adverse effect of antipsychotics with genetics partly underpinning variation in susceptibility among schizophrenia patients. Melanocortin4 receptor(MC4 R) gene, one of the candidate genes for AIMD, has been under-studied in the Chinese patients. We conducted a pharmacogenetic study in a large cohort of Chinese patients with schizophrenia. In this study, we investigated the genetic variation of MC4 R in Chinese population by genotyping two SNPs(rs489693 and rs17782313) in 1,991 Chinese patients and examined association of these variants with the metabolic effects that were often observed to be related to AIMD. Metabolic measures, including body mass index(BMI), waist circumference(WC), glucose, triglyceride, high-density lipoprotein(HDL), and low-density lipoprotein(LDL) levels were assessed at baseline and after 6-week antipsychotic treatment. We found that interaction of SNP×medication status(drug-na?ve/medicated) was significantly associated with BMI, WC, and HDL change %, respectively. Both SNPs were significantly associated with baseline BMI and WC in the medicated group. Moderate association of rs489693 with WC, Triglyceride, and HDL change % were observed in the whole sample. In the drug-na?ve group, we found recessive effects of rs489693 on BMI gain more than 7%, WC and Triglyceride change %, with AA incurring more metabolic adverse effects. In conclusion, the association between rs489693 and the metabolic measures is ubiquitous but moderate. Rs17782313 is less involved in AIMD. Two SNPs confer risk of AIMD to patients treated with different antipsychotics in a similar way. | Yamin Zhang Hongyan Ren Qiang Wang Wei Deng Weihua Yue Hao Yan Liwen Tan Qi Chen Guigang Yang Tianlan Lu Lifang Wang Fuquan Zhang Jianli Yang Keqing Li Luxian Lv Qingrong Tan Hongyan Zhang Xin Ma Fude Yang Lingjiang Li Chuanyue Wang Dai Zhang Liansheng Zhao Huiyao Wang Xiaojing Li Wanjun Guo Xun Hu Yang Tian Xiaohong Ma Tao Li Chinese Antipsychotics Pharmacogenomics Consortium | 2019 | Science China(Life Sciences)2019，62，4： | 3 |
| 4 | Research on the Necessity of Building National-level Grape and Cherry Germplasm Resources Bank in Shandong Province显示文摘At present,the grape and cherry industries in Shandong are in the leading position in China and have driven the development of related high-end manufacturing industries such as wine,brandy,preserved fruit processing,fruit juice processing and health products. Therefore,vigorously developing the grape and cherry industries in Shandong Province and carrying out development and innovation are important parts of Shandong Province in responding to the strategy of national new and old kinetic energy conversion. However,currently the germplasm resources preserved in the fruit tree resources banks in China are only 45% of those in the US and 27. 2% of those in the EU. Moreover,the development of fruit trees resources banks in Shandong is relatively backward in China,and there is still no banks related with grape and cherry germplasm resources in Shandong. Therefore,importance can be attached to the agriculture,forestry,and animal husbandry to build germplasm resources banks for grape and cherry industries in Shandong Province. Building the national-level grape and cherry germplasm resources bank in Shandong Province can also promote the utilization of wild and farm germplasm resources in the future; advance the research on the genes related to disease resistance,stress resistance and quality of grapes and cherries; push forward the construction and development of cherry and grape mutants banks. It is conducive to the research on the agronomic traits of grapes and cherries,and can provide the parents resources for planting innovation and improving the quality of grapes and cherries,as well as promote the development and application of molecular markers of grapes and cherries,including the identification of lines and crossbreeding. Thereby,it cannot only promote the industry development,but also achieve the development of cultivation,breeding and basic research in an all-round way and the development of ' production,study and research' going side by side. | Pengfei WANG Fengshan REN Yongmei WANG Xinying WU Xilong JIANG Yingchun CHEN Shan WANG Qian MU Liying YANG Wanjun CHEN | 2018 | Agricultural Biotechnology2018，7，2： | 3 |

| 8 | Seeding performance of air-assisted centralized seed-metering device for rapeseed显示文摘In order to analyze seed movement characteristics and improve seeding quality of air-assisted centralized metering device for rapeseed,the effects of the model-hole structure on seed feeding performance were investigated using EDEM simulation.Furthermore,the CFD-DEM coupling approach was applied to determine movement trajectories and airflow fields.The impacts of rapeseed varieties and rotational speed on seeding performance were investigated by bench tests.The results showed that the seed feeding quantity increased with the increase of model-hole’s length,depth and section size.Under the model-hole’s depth of 3.0 mm,the type II model-hole and model-hole’s length of 10 mm,both the variation coefficient of seed feeding quantity and hill diameter were lower which meet the seeding quantity requirement of 2 seeds in each hill.It was revealed that the seed population migrated in a large airflow velocity area and the distribution was uniform.The bench tests indicated that rapeseed varieties and rotational speed had a significant effect on the seed feeding quantity in each hill at rotational speed of 10-40 r/min.The variation coefficient of seed feeding quantity in each hill was less than 17.0%for each treatment.The hill diameter,which did not exceed 3.5 cm,tended to reduce with increasing rotational speed.The variation coefficient of seeding quantity in each row and seeding uniformity was less than 6.5%and 32.0%,respectively.Field experiments demonstrated that the seedling was 9-13 plants per meter each row for three rapeseed varieties.The variation coefficient of plants was less than 25.0%for six rows and their yields reached 2761 kg/hm2,which realized the mechanized planting requirements.The results can optimize structure of an air-assisted centralized metering system and improve seeding performance. | Xiaolong Lei Hongji Hu Wenhao Yang Liyang Liu Qingxi Liao Wanjun Ren | 2021 | International Journal of Agricultural and Biological Engineering2021，14，5： | 1 |

| 10 | Unmanned air vehicle adaptability and application evaluation for new rice panicle fertilizers:Fertilizer characteristics and mechanical adaptability显示文摘High-efficiency fertilizers suitable for mechanical spraying can improve the fertilizer application and utilization efficiency.In this study,two types of granular compound fertilizers suitable for unmanned air vehicle spraying were developed using urea,potassium chloride,humic acid,and an amino acid synergist according to the fertilization requirements of rice at the booting stage.The physical and chemical properties of the compound fertilizers were analyzed by Fourier transform infrared spectroscopy and scanning electron microscopy.The release kinetics of the fertilizer was studied via a soil column leaching experiment.The effect of fertilizer particles on unmanned air vehicle spraying uniformity was studied via an orthogonal simulation experiment.Results showed that the chemical interaction between compound-fertilizer raw materials formed complexes such as C-NH-C and-CO-NH-,which caused a change in fertilizer particle morphology.This led to chemical monolayer adsorption or internal fertilizer diffusion,which in turn delayed the fertilizer release by 5−10 d.A simulation bench test showed that the fertilizer particle hardness and roundness exceeded 20 N and 85%,respectively,while the particle size was in the range of 2.07−5.13 mm,which resulted in good unmanned air vehicle spraying uniformity with a lateral variation coefficient of less than 15%.Finally,the experimental field results demonstrated that the new compound fertilizers,when sprayed by an unmanned air vehicle,could improve the economic benefit by 916−2742 CNY ha−1 without reducing the nitrogen utilization rate and rice yield.The new compound fertilizers exhibit delayed release,good spraying uniformity,and improved economic benefit,rendering them suitable for large-scale promotion and application. | Shilin Zhu Wei Zhou Li Zhu Boteng Sun Song Huang Zhenyuan Wu Qin Qin Tao Wang Yong Chen Fei Deng Xiaolong Lei Youfeng Tao Hong Cheng Wanjun Ren | 2022 | Technology in Agronomy2022，2，1： | 0 |
