| 1 | Investigate of in situ sludge reduction in sequencing batch biofilm reactor:Performances,mechanisms and comparison of different carriers显示文摘Biofilm is an effective simultaneous denitrification and in situ sludge reduction system,and the characteristics of different biofilm carrier have important implications for biofilm growth and in situ sludge reduction.In this study,the performance and mechanism of in situ sludge reduction were compared between FSC-SBBR and SC-SBBR with constructed by composite floating spherical carriers(FSC)and multi-faceted polyethylene suspension carriers(SC),respectively.The variation of EPS concentration indicated that the biofilm formation of FSC was faster than SC.Compared with SCSBBR,the FSC-SBBR yielded 0.16 g MLSS/g COD,almost 27.27%less sludge.The average removal rates of COD and NH_(4)^(+)-N were 93.39% and 96.66%,respectively,which were 5.21% and 1.43% higher than the average removal rate of SC-SBBR.Investigation of the mechanisms of sludge reduction revealed that,energy uncoupling metabolism and sludge decay were the main factors for sludge reduction inducing 43.13%and 49.65%less sludge,respectively,in FSC-SBBR.EEM fluorescence spectroscopy and SUVA analysis showed that the hydrolytic capacity of biofilm attached in FSC was stronger than those of SC,and the hydrolysis of EPS released more DOM contributed to lysis-cryptic growth metabolism.In additional,Bacteroidetes and Mizugakiibacter associated with sludge reduction were the dominant phylum and genus in FCS-SBBR.Thus,the effect of simultaneous in situ sludge reduction and pollutant removal in FSC-SBBR was better. | Yonglei Wang Baozhen Liu Kefeng Zhang Yongjian Liu Xuexin Xu Junqi Jia | 2018 | Frontiers of Environmental Science & Engineering2018，12，5： | 7 |
| 2 | Coordinated transcription of ANRIL and P16 genes is silenced by P16 DNA methylation显示文摘Objective: To investigate the relationship between the transcription of ANRIL, P15, P14 and P16 at the same locus and the regulation mechanism of ANRIL.Methods: Publicly available database of Cancer Cell Line Encyclopedia(CCLE) was used in bioinformatic analyses. Methylation of Cp G islands was detected by denaturing high performance liquid chromatography(DHPLC). Gene transcript levels were determined using quantitative real-time polymerase chain reaction(q RTPCR) assays. An engineered P16-specific transcription factor and DNA methyltransferase were used to induce P16-specific DNA demethylation and methylation.Results: The expression level of ANRIL was positively and significantly correlated with that of P16 but not with that of P15 in the CCLE database. This was confirmed in human cell lines and patient colon tissue samples. In addition, ANRIL was significantly upregulated in colon cancer tissues. Transcription of ANRIL and P16 was observed only in cell lines in which the P16 alleles were unmethylated and not in cell lines with fully methylated P16 alleles.Notably, P16-specific methylation significantly decreased transcription of P16 and ANRIL in BGC823 and GES1 cells. In contrast, P16-specific demethylation re-activated transcription of ANRIL and P16 in H1299 cells(P<0.001).Alteration of ANRIL expression was not induced by P16 expression changes.Conclusions: ANRIL and P16 are coordinately transcribed in human cells and regulated by the methylation status of the P16 Cp G islands around the transcription start site. | Ying Gan Wanru Ma Xiuhong Wang Juanli Qiao Baozhen Zhang Chenghua Cui Zhaojun Liu Dajun Deng | 2018 | Chinese Journal of Cancer Research2018，30，1： | 2 |
| 3 | Geothermal occurrence analysis of Dongying Formation in Tanggu area of Tianjin显示文摘Based on introducing geological structure of Tanggu area,the authors analyzed the sedimentary environment of Paleogene Dongying Formation,and further analyzed its geothermal occurrence. The studied area spans two grade Ⅳ tectonic units which are Beitang depression and Banqiao depression. The studied area is mainly located in the Tanggu nose-like structure which is the secondary structure of Beitang depression. Its existence affects the sedimentary distribution of the part strata of Paleogene. The depositions of Dongying Ⅲ( SQEd3) and DongyingⅡ( SQEd2) are mainly delta front facies and lake sand bars which are propitious to the geothermal fluid enrichment. The favorable enrichment region of geothermal fluid is located in south HetouTanggu. Most of DongyingⅠ( SQEd1) changes into swamp plain deposition,only the northeast part of this area is the distributary riverway facies with developed sand layers. There is the favorable enrichment region of geothermal fluid. The hydraulic connection is weak among the geothermal reservoirs of Dongying Formation and its overlying Guantao and Minghuazhen formations. The underlying Shahejie Formation geothermal reservoir provides a steady stream of fluid supply and ground pressure protection for Dongying Formation geothermal reservoir. | LIU Jiulong JIN Baozhen LI Yuanyuan WANG Jige YUE Liyan WANG Xi | 2014 | Global Geology2014，17，3： | 2 |
| 4 | Performance of landfill leachate treatment system with disc-tube reverse osmosis units显示文摘Reverse osmosis system with the disc-tube mod-ule(DT-RO)was applied to treat landfill leachate on full scale at the Changshengqiao Sanitary Landfill,Chongqing City,China.In the first six-mouth operation phase,the treatment performance of DT-RO system had been excel-lent and stable.The removal rate of chemical oxygen demand(COD),total organic carbon(TOC),electrical con-ductivity(EC),and ammonia nitrogen(NH 3-N)reached 99.2–99.7%,99.2%,99.6%,and over 98%,respectively.The rejection of Ca^(2+),Ba^(2+),and Mg^(2+)was over 99.9%,respectively.Suspended solid(SS)was not detectedin prod-uct water.Effective methods had been adopted to control membrane fouling,of which chemical cleaning is of utmost importance to guarantee the long smooth operation of the DT-ROsystem.The DT-ROsystemiscleanedinturnswith Cleaner A and Cleaner C.At present,the 1st stage cleaning cycle by Cleaner A and Cleaner C is conducted every 100 and500 h,respectively,dependingonrawthewaterquality. | Yanping LIU Xiujin LI Baozhen WANG Shuo LIU | 2008 | Frontiers of Environmental Science & Engineering2008，2，1： | 2 |
| 5 | Extensive game analysis and improvement strategy of DPOS consensus mechanism显示文摘Delegated proof-of-stake(DPOS) consensus mechanism is widely adopted in blockchain platforms, but problems exist in its current applications. In order to explore the security risks in the voting attack of the DPOS consensus mechanism, an extensive game model between nodes was constructed, and it was concluded that the DPOS consensus mechanism relies too much on tokens, and the possibility of node attacks is very high. In order to solve the problems of frequent changes of DPOS consensus mechanism nodes, inactive node voting, excessive reliance on tokens, and malicious nodes, a dynamic, credible, and attack-evading DPOS consensus mechanism was proposed. In addition, the Python simulation results show that the improved Bayesian voting algorithm is effective in calculating node scores. | Wang Lei Zhu Qinghua Li Baozhen | 2021 | The Journal of China Universities of Posts and Telecommunications2021，28，5： | 2 |
| 6 | Highly dispersed Pt clusters encapsulated in MIL-125-NH_(2) via in situ auto-reduction method for photocatalytic H_(2) production under visible light显示文摘Efficient hydrogen production via photocatalysis with high utilization efficiency of Pt cocatalyst is of great importance for sustainable development. In this work, we report an in situ auto-reduction strategy to encapsulate highly dispersed Pt clusters inside the cages of MIL-125-NH_(2). The amino groups in MIL-125-NH_(2) first react with formaldehyde to form reducing groups (i.e.,–NH-CH_(2)OH), which can in situ auto-reduce the confined Pt^(2+) ions to ultrasmall Pt clusters within the cavities. With optimized Pt content, photocatalytic H_(2) production over the obtained Pt(1.5)/MIL-125-NH-CH_(2)OH catalyst with 1.43 wt.% Pt loading achieved as high as 4,496.4 µmol·g^(-1)·h^(-1) under visible light (λ > 420 nm) due to the facilitated transfer and separation of the photo-induced charger carriers arising from the synergetic effects between highly dispersed Pt clusters and MIL-125-NH-CH_(2)OH framework. This in situ auto-reduction strategy may be extended to encapsulate various kinds of metal or alloy clusters/nanoparticles within amino-functioned metal-organic frameworks (MOFs) with superior properties and excellent performance. | Xiubing Huang Xiangjun Li Qingjie Luan Kaiyue Zhang Zhenyu Wu Baozhen Li Zuoshuai Xi Wenjun Dong Ge Wang | 2021 | Nano Research2021，14，11： | 2 |

| 10 | Long Non-coding RNA Derived from lncRNA–mRNA Co-expression Networks Modulates the Locust Phase Change显示文摘Long non-coding RNAs(lncRNAs)regulate various biological processes ranging from gene expression to animal behavior.Although protein-coding genes,microRNAs,and neuropeptides play important roles in the regulation of phenotypic plasticity in migratory locust,empirical studies on the function of lncRNAs in this process remain limited.Here,we applied high-throughput RNA-seq to compare the expression patterns of lncRNAs and mRNAs in the time course of locust phase change.We found that lncRNAs responded more rapidly at the early stages of phase transition.Functional annotations demonstrated that early changed lncRNAs employed different pathways in isolation and crowding phases to cope with changes in the population density.Two overlapping hub lncRNA loci in the crowding and isolation networks were screened for functional verification.One of them,LNC1010057,was validated as a potential regulator of locust phase change.This work offers insights into the molecular mechanism underlying locust phase change and expands the scope of lncRNA functions in animal behavior. | Ting Li Bing Chen Pengcheng Yang Depin Wang Baozhen Du Le Kang | 2020 | Genomics, Proteomics & Bioinformatics2020，18，6： | 1 |
