| 1 | Evaluation of mercury speciation and removal through air pollution control devices of a 190 MW boiler显示文摘Air pollution control devices(APCDs) are installed at coal-fired power plants for air pollutant regulation.Selective catalytic reduction(SCR) and wet flue gas desulfurization(FGD) systems have the co-benefits of air pollutant and mercury removal.Configuration and operational conditions of APCDs and mercury speciation affect mercury removal efficiently at coal-fired utilities.The Ontario Hydro Method(OHM) recommended by the U.S.Environmental Protection Agency(EPA) was used to determine mercury speciation simultaneously at five sampling locations through SCR-ESP-FGD at a 190 MW unit.Chlorine in coal had been suggested as a factor affecting the mercury speciation in flue gas;and low-chlorine coal was purported to produce less oxidized mercury(Hg2+) and more elemental mercury(Hg0 ) at the SCR inlet compared to higher chlorine coal.SCR could oxidize elemental mercury into oxidized mercury when SCR was in service,and oxidation efficiency reached 71.0%.Therefore,oxidized mercury removal efficiency was enhanced through a wet FGD system.In the non-ozone season,about 89.5%-96.8% of oxidized mercury was controlled,but only 54.9%-68.8% of the total mercury was captured through wet FGD.Oxidized mercury removal efficiency was 95.9%-98.0%,and there was a big difference in the total mercury removal efficiencies from 78.0% to 90.2% in the ozone season.Mercury mass balance was evaluated to validate reliability of OHM testing data,and the ratio of mercury input in the coal to mercury output at the stack was from 0.84 to 1.08. | Chengli Wu Yan Cao Zhongbing Dong Chinmin Cheng Hanxu Li Weiping Pan | 2010 | Journal of Environmental Sciences2010，22，2： | 13 |

| 6 | Genetic modification of miR-34a enhances efficacy of transplanted human dental pulp stem cells after ischemic stroke显示文摘Human dental pulp stem cells(hDPSCs) promote recovery after ischemic stro ke;however,the therapeutic efficacy is limited by the poor survival of transplanted cells.For in vitro expe riments in the present study,we used oxygen-glucose deprivation/reoxygenation in hDPSCs to mimic cell damage induced by ischemia/reperfusion.We found that miRNA-34a-5p(miR-34a) was elevated under oxygen-glucose deprivation/reoxygenation conditions in hDPSCs.Inhibition of miR-34a facilitated the prolife ration and antioxidant capacity and reduced the apoptosis of hDPSCs.Moreove r,dual-luciferase reporter gene assay showed WNT1and SIRT1 as the targets of miR-34a.In miR-34a knockdown cell lines,WNT1 suppression reduced cell prolife ration,and SIRT1 suppression decreased the antioxidant capacity.Togethe r,these results indicated that miR-34a regulates cell prolife ration and antioxidant stress via targeting WNT1 and SIRT1,respectively.For in vivo expe riments,we injected genetically modified hDPSCs(anti34a-hDPSCs) into the brains of mice.We found that anti34a-hDPSCs significantly inhibited apoptosis,reduced cerebral edema and cerebral infarct volume,and improved motor function in mice.This study provides new insights into the molecular mechanism of the cell prolife ration and antioxidant capacity of hDPSCs,and suggests a potential gene that can be targeted to improve the survival rate and efficacy of transplanted hDPSCs in brain after ischemic stroke. | Jianfeng Wang Peibang He Qi Tian Yu Luo Yan He Chengli Liu Pian Gong Yujia Guo Qingsong Ye Mingchang Li | 2023 | Neural Regeneration Research2023，18，9： | 1 |

| 8 | Functional Recovery with Electro-Acupuncture Stimulation in an Mecp2-Knockout Rat Model of Rett Syndrome显示文摘Rett syndrome is a progressive neurodevelopmental disorder that lacks effective treatments.Although deep-brain stimulation can alleviate some symptoms in Rett model mice,this interventional manipula-tion requires deliberate surgical operations.Here,we report that electro-acupuncture stimulation(EAS)can ameliorate symptoms of an Mecp2-knockout rat model of Rett syndrome from the remote acupoints Baihui(GV 20),Yongquan(KI 1),and Shenmen(HT 7).We find that EAS not only prolongs the survival time of Rett rats,but also improves their behavior ability,including locomotion,motor coordination,and social interaction.Neural activation was observed in the substantia nigra of the midbrain,corpus striatum,and cerebral cortex of wild-type and Rett model rats,as reflected by the increased expression of the c-Fos protein.Hence,EAS provides a potential promising therapeutic tool for treating neurodevel-opmental diseases. | Yanhong Sun Zhifang Chen Yi Xu Yuefang Zhang Zhilei Ge Chenglie Lin Yi Zhou Fangfei Zhao Meiling Yan Xinyi Liu Ying Zhu Jimin Gao Hongyi Li Lihua Wang Jun Hu Zilong Qiu Chunhai Fan | 2022 | Engineering2022，8，5： | 0 |
| 9 | Effect of reduction-oxidation treatment on structure and catalytic properties of ordered mesoporous Cu-Mg-Al composite oxides显示文摘Ordered mesoporous Cu–Mg–Al composite oxides were synthesized via the one-pot evaporation-induced self-assembly strategy. Using this method, copper was first homogeneously incorporated into the ordered mesoporous spinel matrix. After H2 reduction treatment,according to X-ray diffraction(XRD) and transmission electron microscopy(TEM) results, copper existed as metallic nanoparticles with the size of 6–10 nm that well decorated the parent mesoporous skeleton. The metallic nanoparticles were then re-oxidized to copper oxide when exposed to air or during CO oxidation reaction at low temperatures. Thus, copper migrated from bulk spinel phase to the surface after the reduction–oxidation treatment. Moreover, the copper on the surface was re-incorporated into the bulk spinel phase by further thermaltreatment at much higher temperature in the presence of air. The correlation between the state of copper in the mesoporous composite oxides and the catalytic performance toward CO oxidation was studied. It was found that copper existed as oxide nanoparticles on the surface of mesoporous Mg–Al skeleton is much more active than that existed as lattice Cu ions in spinel phase. | Jingting Lu Yan Zhang Chengli Jiao Suresh Kumar Megarajan Dong Gu Guocheng Yang Heqing Jiang Chunjiang Jia Ferdi Schiith | 2015 | Science Bulletin2015，60，12： | 0 |
