| 1 | Sequential use of ultraviolet light and chlorine for reclaimed water disinfection显示文摘Several disinfection processes of ultraviolet (UV),chlorine or UV followed by chlorine were investigated in municipal wastewater according to the inactivation of Escherichia coli,Shigella dysenteriae and toxicity formation.The UV inactivation of the tested pathogenic bacteria was not affected by the quality of water.It was found that the inactivated bacteria were obviously reactivated after one day in dark.Fluorescent light irradiation increased the bacteria repair.The increase of UV dosage could cause more damage to bacteria to inhibit bacteria self-repair.No photoreactivation was detected when the UV dose was up to 80 mJ/cm2 for E.coli DH5α,and 23 mJ/cm2 for S.dysenteriae.Nevertheless,sequential use of 8 mJ/cm2 of UV and low concentration of chlorine (1.5 mg/L) could effectively inhibit the photoreactivation and inactivate E.coli below the detection limits within seven days.Compared to chlorination alone,the sequential disinfection decreased the genotoxicity of treated wastewater,especially for the sample with high NH 3-N concentration. | Xiujuan Wang Xuexiang Hu Chun Hu Dongbin Wei | 2011 | Journal of Environmental Sciences2011，23，10： | 8 |
| 2 | Photolysis of chlortetracycline in aqueous solution:Kinetics,toxicity and products显示文摘The aqueous photodegradation of the widely used antibiotic chlortetracycline(CTC) was investigated under simulated sunlight.The quantum yield of photodegradation increased from 3.3 × 10-4 to 8.5 × 10-3 within the pH range of 6.0 to 9.0.The presence of Ca2+,Fe3+,and NO3-enhanced the photodegradation of CTC,whereas Mg2+,Mn2+,and Zn2+ inhibited the degradation with the order Mn2+ > Zn2+ > Mg2+ at pH 7.3.The monovalent cations(Na+ and K+) had negligible effect on the photolysis of CTC.Fulvic acid(FA) decreased the photodegradation of CTC due to light screening effect.Hydrogen peroxide(H2O2) was formed concurrently with direct photodegradation of CTC.The generation rate of H2O2 increased from 0.027 to 0.086 μmol/(L.min) when the pH ranged from 6.0 to 9.0.The CTC solution was about three-fold more toxic to the Photobacterium phosphoreum bacteria after irradiation,suggesting that the photoproducts and H2O2 formed in the CTC solution exhibited high risk on the bacteria.By LC-ESI(+)-MS,the photoproducts of CTC were identified.The direct photodegradation of CTC was involved in hydroxylation and N-demethyl/dedismethyl processes.The main photoproducts included the iso-CTC analog containing hydroxyl groups(m/z 511.4 and 495.4),and the N-demethyl/dedismethyl products of the photoproduct m/z 495.4(m/z 481.3 and 467.4).In addition,the photochemical dechlorination of CTC led to tetracycline(m/z 445.5). | Yong Chen Hua Li Zongping Wang Tao Tao Dongbin Wei Chun Hu | 2012 | Journal of Environmental Sciences2012，24，2： | 6 |
| 3 | Research on the ecological compensation standard of the basin pollution control project based on evolutionary game theory and by taking Xiangjiang River as a case显示文摘Ecological compensation is a new resource and environment management model.As one of the main areas for implementing ecological compensation policies,basin ecological compensation has become an important measure for encouraging basin pollution control projects and improving the quality of regional economic development.By applying the basic game analysis of evolutionary game theory and building an evolutionary game model with a“reward-punishment”mechanism,this paper compares the interest-related decision-making behaviors of the upstream and downstream stakeholders of basin ecological compensation.By using data on the water quality of Xiangjiang River Basin,this paper calculates the rewards and penalties in different intervals by building a parametric regression mathematical model and employing the local linear regression method.Results show that a decline in water quality should be fined RMB 925500 yuan,an improvement in water quality should be awarded RMB 1227800 yuan,and a deteriorating water quality should be severely fined RMB 5087600 yuan. | Dongbin HU Huiwu LIU Xiaohong CHEN Yang CHEN | 2019 | Frontiers of Engineering Management2019，6，4： | 4 |
| 4 | Novel Combination Therapy for Triple-Negative Breast Cancer based on an Intelligent Hollow Carbon Sphere显示文摘Triple-negative breast cancer(TNBC)is a subtype of breast cancer with high mortality,and the efficacy of monotherapy for TNBC is still disappointing.Here,we developed a novel combination therapy for TNBC based on a multifunctional nanohollow carbon sphere.This intelligent material contains a superadsorbed silicon dioxide sphere,sufficient loading space,a nanoscale hole on its surface,a robust shell,and an outer bilayer,and it could load both programmed cell death protein 1/programmed cell death ligand 1(PD-1/PD-L1)small-molecule immune checkpoints and small-molecule photosensitizers with excellent loading contents,protect these small molecules during the systemic circulation,and achieve accumulation of them in tumor sites after systemic administration followed by the application of laser irradiation,thereby realizing dual attack of photodynamic therapy and immunotherapy on tumors.Importantly,we integrated the fasting-mimicking diet condition that can further enhance the cellular uptake efficiency of nanoparticles in tumor cells and amplify the immune responses,further enhancing the therapeutic effect.Thus,a novel combination therapy“PD-1/PD-L1 immune checkpoint blockade+photodynamic therapy+fasting-mimicking diet”was developed with the aid of our materials,which eventually achieved a marked therapeutic effect in 4T1-tumor-bearing mice.The concept can also be applied to the clinical treatment of human TNBC with guiding significance in the future. | Yue Yin Yaping Yan Biao Fan Wenping Huang Jie Zhang Hai-Yan Hu Xiaoqiong Li Dongbin Xiong Shu-Lei Chou Yao Xiao Hai Wang | 2023 | Research2023，，4： | 1 |
