| 1 | Export and remineralization of POM in the Southern Ocean and the South China Sea estimated from ^(210)Po/^(210)Pb disequilibria显示文摘Disequilibria between 210Po and 210Pb in the upper water and their potential applications as a proxy of particle export and remineralization were examined in the Southern Ocean (station IV3) and the South China Sea (NS44). 210Po was deficit in surface waters but excessive relative to 210Pb in subsurface waters. Good positive correlation between 210Po and particulate organic carbon (POC) indicated deficits and excess of 210Po resulted from particulate organic matter (POM) export and remineralization respectively, which was also supported by the decreased δ 13C and increased δ 15N downwards as a result of particle remineralization. On the basis of 210Po/210Pb box-model, POC export flux out of the surface waters were 1.2 mmol C·m-2·d-1 and 2.3 mmol C·m-2·d-1 for station NS44 and IV3, respectively. In the subsurface waters, remineralization fluxes of 210Po were 0.062 Bq·m-2·d-1 and 0.566 Bq·m-2·d-1 for station NS44 and IV3 along with the recycle efficiency of 52±26% and 119±52%, respectively. Remineralized fluxes of POM derived from 210Po and exported POC were 0.6 mmol C·m-2·d-1 and 2.7 mmol C·m-2·d-1 for NS44 and IV3. This study suggested that 210Po was a powerful tracer of particle export and remineralization. | YANG WeiFeng HUANG YiPu CHEN Min QIU YuSheng PENG AnGuo ZHANG Lei | 2009 | Chinese Science Bulletin2009，54，12： | 6 |

| 3 | Isotherm Equation Study of F Adsorbed from Water Solution by Fe2(SO4)3-modified Granular Activated Alumina显示文摘The adsorption equilibrium of a fluoride solution on 1-2 mm granular activated alumina modified by Fe2(SO4)3 solution was investigated.The experiments were conducted using a wide range of initial fluoride concentrations(0.5 to 180 mg·L-1 at pH~7.0) and an adsorbent dose of 1.0 g·L-1.The application of Langmuir and Freundlich adsorption isotherm models(linear and nonlinear forms) generally showed that a single Langmuir or Freundlich equation cannot fit the entire concentration gap.Experimental data on low equilibrium concentrations(0.1 to 5.0 mg·L-1) was in line with both Langmuir and Freundlich isotherm models,whereas that of high equilibrium concentrations(5.0 to 150 mg·L-1) was more in line with the Freundlich isotherm model.A new LangmuirFreundlich function was used for the entire concentration gap,as well as for low and high concentrations. | DANG Dan DING Wenming CHENG Anguo LIU Shuming ZHANG Xu | 2011 | Chinese Journal of Chemical Engineering2011，19，4： | 5 |

| 6 | Study on the Mechanism of Zn2SiO4 Formation in S Zorb Sorbents and Its Inhibition Methods显示文摘S Zorb adsorptive desulfurization technology is of great significance on the production of clean gasoline in China, but the formation of Zn_2SiO_4 during the operation in sorbents would bring forth negative impacts on the desulfurization performance and the stability of the processing unit. By using the in-situ TPO, XRD, and IR techniques to study the mechanism of Zn_2SiO_4 formation under operating conditions, it was found that the coexistence of acid and hydrothermal conditions could accelerate the formation of Zn_2SiO_4. Moreover, the study of Zn_2SiO_4 inhibition method indicated that the decrease of oxygen concentration in regeneration gas would inhibit the rate of Zn_2SiO_4 formation, and the regeneration of Zn S would take place in a mild regeneration condition. | Xu Li Zou Kang Xu Guangtong Yang Xingyuan Xu Hua Mao Anguo | 2016 | China Petroleum Processing & Petrochemical Technology2016，18，2： | 5 |
| 7 | Purification of 3-hydroxypropionitrile by wiped molecular distillation显示文摘A new separation method, wiped molecular distillation (WMD), was applied and experimental work was carried out to study the effect of operation parameters such as distillation temperature, pressure, feed flow rate, wiped speed and the separation stages on purifying the raw material containing 95% 3-hydroxypropionitrile (HPN). It was an excellent result that the mass concentration of HPN in the final product can be more than 99.5% under the optimistic operation conditions. The high purity cannot be achieved with normal separating method includ- ing rectification and extraction in practice. As for the raw material, a function of HPN purity in distillate was plotted with distillation temperature and pressure in experiment ranges. According to the experiment data obtained and the theory in molecular distillation, the distillation speed of HPN and separation efficiency were computed. It was concluded that the distillation speed of HPN and the separation efficiency were satisfying for industrial production. | XU Songlin XIANG Aishuang YING Anguo | 2004 | Science China Chemistry2004，47，6： | 4 |
| 8 | Effect of Sini San Freeze-dried powder on sleep-waking cycle in insomnia rats显示文摘OBJECTIVE: To investigate the effects of the Sini San at different doses on each sleeping state[slow-wave sleep 1(SWS1), slow-wave sleep 2(SWS2), rapid-eye-movement(REM), wakefulness(W)] in insomnia rats and to identify its mode of ac-tion for improving sleep.METHODS: The insomnia rats were randomly divided into a high-, medium- or low-dose group of Sini San(equal to crude drug 8.8, 4.4, or 2.2 g/kg, respectively) for seven consecutive days.RESULTS: Compared with pre-administration,SWS2 was significantly increased after administration of the low dose. Compared with pre-administration, W was significantly decreased and SWS1,SWS2, and the total sleeping time(TST) were markedly increased after administration of the medium dose. Compared with pre-administration, W was significantly decreased and SWS1, SWS2, rapid-eye-movement sleep, and TST were significantly longer after administration of the high dose. The effects of Sini San on sleep-wake cycle are dose-dependent.CONCLUSION: The results suggest that Sini San extends SWS1 and SWS2, which increases the total sleeping time. | Xingke Yan Zeguo Zhang Fuju Xu Yuefeng Li Tiantian Zhu Chongbing Ma Anguo Liu | 2014 | Journal of Traditional Chinese Medicine2014，34，5： | 4 |
| 9 | Synthesis of molybdenum disulfide/reduced graphene oxide composites for effective removal of Pb(Ⅱ) from aqueous solutions显示文摘In this work,a facile method was adopted to synthesize molybdenum disulfide/reduced graphene oxide(MoS_2/rGO) composites through an L-cysteine-assisted hydrothermal technique.The as-prepared MoS_2/rGO composites were firstly applied as adsorbents for efficient elimination of Pb(Ⅱ) ions.Batch adsorption experiments showed that the adsorption of Pb(Ⅱ) on MoS_2/rGO followed pseudo-second-order kinetic model well.The adsorption of Pb(Ⅱ) was intensely pH-dependent,ionic strength-dependent at pH < 9.0 and ionic strength-independent at pH > 9.0.The presence of humic acid(HA) enhanced Pb(Ⅱ)adsorption obviously.The MoS_2/rGO composites exhibited excellent adsorption capacity of384.16 mg g ~1 at pH 5.0 and T= 298.15 K,which was superior to MoS_2(279.93 mg g ~1) and many other adsorbents.The thermodynamic parameters suggested that the adsorption process of Pb(Ⅱ) on MoS_2/rGO composites was spontaneous(AG~θ < 0) and endothermic(AH~θ > 0).The interaction of Pb(Ⅱ) and MoS_2/rGO was mainly dominated by electrostatic attraction and surface complexation between Pb(Ⅱ) and oxygen-containing functional groups of MoS_2/rGO.This work highlighted the application of MoS_2/rGO as novel and promising materials in the efficient elimination of Pb(Ⅱ) from contaminated water and industrial effluents in environmental pollution management. | Yi Du Jian Wang Yidong Zou Wen Yao Jing Hou Liangshu Xia Anguo Peng Ahmed Alsaedi Tasawar Hayat Xiangke Wang | 2017 | Science Bulletin2017，62，13： | 4 |
| 10 | High-throughput screening for amyloid-β binding natural small-molecules based on the combinational use of biolayer interferometry and UHPLC−DAD-Q/TOF-MS/MS显示文摘Discovery of drugs rapidly and effectively is an important aspect for Alzheimer's disease(AD).In this study,a novel high-throughput screening(HTS)method aims at screening the small-molecules with amyloid-β(Aβ)binding affinity from natural medicines,based on the combinational use of biolayer interferometry(BLI)and ultra-high-performance liquid chromatography coupled with diode-array detector and quadrupole/time-of-flight tandem mass spectrometry(UHPLC−DAD-Q/TOF-MS/MS)has been firstly developed.Briefly,the components in natural medicines disassociated from biotinylated Aβwere collected to analyze their potential Aβbinding affinity by UHPLC−DAD-Q/TOF-MS/MS.Here,baicalein was confirmed to exhibit the highest binding affinity with Aβin Scutellaria baicalensis.Moreover,polyporenic acid C(PPAC),dehydrotumulosic acid(DTA),and tumulosic acid(TA)in Kai-Xin-San(KXS)were also identified as potent Aβinhibitors.Further bioactivity validations indicated that these compounds could inhibit Aβfibrillation,improve the viability in Aβ-induced PC-12 cells,and decrease the Aβcontent and improve the behavioral ability in Caenorhabditis elegans.The molecular docking results confirmed that PPAC,DTA,and TA possessed good binding properties with Aβ.Collectively,the present study has provided a novel and effective HTS method for the identification of natural inhibitors on Aβfibrillation,which may accelerate the process on anti-AD drugs discovery and development. | Minsong Guo Fengdan Zhu Wenqiao Qiu Gan Qiao Betty Yuen-Kwan Law Lu Yu Jianming Wu Yong Tang Chonglin Yu Dalian Qin Xiaogang Zhou Anguo Wu | 2022 | Acta Pharmaceutica Sinica B2022，12，4： | 3 |
| 11 | Sedative and hypnotic effect of freeze-dried paeoniflorin and Sini San freeze-dried powder in pentobarbital sodium-induced mice显示文摘OBJECTIVE: To investigate the sedative and hypnotic activity of paeoniflorin and freeze-dried Sini San powder on mice and provide a reliable method for determining the pharmacodynamic material basis of Sini San.METHODS: Male adult mice weighing 20-22 g were used in this study. Three experiments were carried out. Synergism with pentobarbital was used as an index for hypnotic effect. Loss of the righting reflex was used to determine the start of sleep.Sleep latency and sleeping time were recorded in each experiment.RESULTS: The coefficient of variation of the suprathreshold dose(55 mg/kg) was significantly lower than that of the threshold dose. The sleep latency of mice was significantly decreased, and the sleeping time of mice was significantly prolonged. The effects of paeoniflorin and Sini San on prolonging the sleeping time of mice induced by pentobarbital sodium were significantly stronger than those in the control group.CONCLUSION: Paeoniflorin produces significant sedative and hypnotic effects, and there is an obvious dose-effect relationship. | Yuefeng Li Pingan Wu Yanmei Ning Xingke Yan Tiantian Zhu Chongbing Ma Anguo Liu | 2014 | Journal of Traditional Chinese Medicine2014，34，2： | 2 |
