| 1 | Optimization and Effects of Catalytic Ozonation of Actual Phenolic Wastewater by CuO/Al2O3显示文摘In order to improve the ability of ozone to catalyze the degradation of phenolic pollutants in wastewater,the CuO/Al2O3 catalysts was prepared by the impregnation precipitation method and an ozone catalytic oxidation system was constructed.The actual phenolic sewage was used as the treatment object.And the reaction conditions of the system were optimized,and the treatment effect was determined,while the non-catalytic system was used as a control group.At the same time,the influence of salt and ammonia nitrogen related water quality on the system was studied.The optimal reaction conditions for the treatment of phenolic wastewater covered:a catalyst dosage of 30 g/L,an ozone flow rate of 0.3 m3/h,a pH value of 8.80,and a reaction time of 15 minutes.Under these conditions,the phenol and COD removal rates of the system reached 98.7%and 49.4%,respectively,which were by 31.3 percentage points and 16.2 percentage points higher than that of the ozonation system alone.The salt and ammonia nitrogen in the sewage can reduce the oxidation effect of the system.When the salinity reached 10%and the ammonia nitrogen content reached 13 000 mg/L,the removal rate of phenol could be reduced by about 20%.The results of this paper have a reference value for phenol wastewater treatment engineering. | Ma Rui Liu Guangmin Feng Sihui Qiu Xiaoyu Zhang Yanqing Xia Shumei Xue Jianliang | 2019 | China Petroleum Processing & Petrochemical Technology2019，21，3： | 3 |

| 5 | Enhancement of CAR-T cell activity against cholangiocarcinoma by simultaneous knockdown of six inhibitory membrane proteins显示文摘Background:Existing treatments for cholangiocarcinoma have poor efficacy.However,chimeric antigen receptor-T(CAR-T)cells are emerging as a potential therapeutic strategy.Solid tumors possess multiple adverse factors in an immunosuppressive microenvironment that impair CAR-T cell infiltration and function.This study aimed to improve the function of CAR-T cells through knock down immune checkpoints and immunosuppressive molecular receptors.Methods:We evaluated the expression of epidermal growth factor receptor(EGFR)and B7 homolog 3 protein(B7H3)antigens in cholangiocarcinoma tissues using immunohistochemistry and screened specific immune checkpoints in the cholangiocarcinoma microenvironment via flow cytometry.Subsequently,we engineered CAR-T cells targeting EGFR and B7H3 antigens.We simultaneously knocked down immune checkpoints and immunosuppressive molecular receptors in CAR-T cells by constructing two clusters of small hairpin RNAs and evaluated the engineered CAR-T cells for antitumor activity both in vitro,using tumor cell lines and cholangiocarcinoma organoid models,and in vivo,using humanized mouse models.Results:We observed high expression of EGFR and B7H3 antigens in cholangiocarcinoma tissues.EGFR-CAR-T and B7H3-CAR-T cells demonstrated specific anti-tumor activity.We found an abundance of programmed cell death protein 1(PD-1),T cell immunoglobulin and mucin domain-containing protein 3(Tim-3),and T cell immunoglobulin and ITIM domain(Tigit)on infiltrated CD8^(+)T cells in the cholangiocarcinoma microenvironment.We then decreased the expression of these 3 proteins on the surface of CAR-T cells,named PTG-scFV-CAR-T cells.Furthermore,we knocked-down the expression of transforming growth factor beta receptor(TGFβR),interleukin-10 receptor(IL-10R),and interleukin-6 receptor(IL-6R)of PTG-scFV-CAR-T cells.Those cells,named PTG-T16R-scFVCAR-T cells,potently killed tumor cells in vitro and promoted apoptosis of tumor cells in a cholangiocarcinoma organoidmodel.Finally,the PTG-T16R-scFv-CART cells showed greater inhibitory effect on tumor growth in vivo,and were superior in prolonging the survival of mice.Conclusions:Our results revealed that PTG-T16R-scFV-CAR-T cells with knockdown of sextuplet inhibitory molecules exhibited strong immunity against cholangiocarcinoma and long-term efficacy both in vitro and in vivo.This strategy provides an effective and personalized immune cell therapy against cholangiocarcinoma. | Yidan Qiao Jie Chen Xuemei Wang Shumei Yan Jizhou Tan Baijin Xia Yongjian Chen Keming Lin Fan Zou Bingfeng Liu Xin He Yiwen Zhang Xu Zhang Hui Zhang Xiangyuan Wu Lijuan Lu | 2023 | Cancer Communications2023，43，7： | 0 |
