| 1 | Phase I study of CAR-T cells with PD-1 and TCR disruption in mesothelin-positive solid tumors显示文摘Programmed cell death protein-1(PD-1)-mediated immunosuppression has been proposed to contribute to the limited clinical efficacy of chimeric antigen receptor T(CAR-T)cells in solid tumors.We generated PD-1 and T cell receptor(TCR)deficient mesothelin-specific CAR-T(MPTK-CAR-T)cells using CRISPR-Cas9 technology and evaluated them in a dose-escalation study.A total of 15 patients received one or more infusions of MPTK-CAR-T cells without prior lymphodepletion.No dose-limiting toxicity or unexpected adverse events were observed in any of the 15 patients.The best overall response was stable disease(2/15 patients).Circulating MPTK-CAR-T cells peaked at days 7–14 and became undetectable beyond 1 month.TCR-positive CAR-T cells rather than TCR-negative CAR-T cells were predominantly detected in effusion or peripheral blood from three patients after infusion.We further confirmed the reduced persistence of TCR-deficient CAR-T cells in animal models.Our results establish the preliminary feasibility and safety of CRISPR-engineered CAR-T cells with PD-1 disruption and suggest that the natural TCR plays an important role in the persistence of CAR-T cells when treating solid tumors. | Zhenguang Wang Na Li Kaichao Feng Meixia Chen Yan Zhang Yang Liu Qingming Yang Jing Nie Na Tang Xingying Zhang Chen Cheng Lianjun Shen Jiaping He Xun Ye Wei Cao Haoyi Wang Weidong Han | 2021 | Cellular & Molecular Immunology2021，18，9： | 7 |

| 3 | A proof of concept for neutralizing antibody-guided vaccine design against SARS-CoV-2显示文摘Mutations and transient conformational movements of the receptor binding domain(RBD)that make neutralizing epitopes momentarily unavailable present immune escape routes for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).To mitigate viral escape,we developed a cocktail of neutralizing antibodies(NAbs)targeting epitopes located on different domains of spike(S)protein.Screening of a library of monoclonal antibodies generated from peripheral blood mononuclear cells of COVID-19 convalescent patients yielded potent NAbs,targeting the N-terminal domain(NTD)and RBD domain of S,effective at n M concentrations.Remarkably,a combination of RBD-targeting NAbs and NTD-binding NAbs,FC05,enhanced the neutralization potency in cell-based assays and an animal model.Results of competitive surface plasmon resonance assays and cryo-electron microscopy(cryo-EM)structures of antigen-binding fragments bound to S unveil determinants of immunogenicity.Combinations of immunogens,identified in the NTD and RBD of S,when immunized in rabbits and macaques,elicited potent protective immune responses against SARS-CoV-2.More importantly,two immunizations of this combination of NTD and RBD immunogens provided complete protection in macaques against a SARS-CoV-2 challenge,without observable antibody-dependent enhancement of infection.These results provide a proof of concept for neutralization-based immunogen design targeting SARS-CoV-2 NTD and RBD. | Li Zhang Lei Cao Xing-Su Gao Bin-Yang Zheng Yong-Qiang Deng Jing-Xin Li Rui Feng Qian Bian Xi-Ling Guo Nan Wang Hong-Ying Qiu Lei Wang Zhen Cui Qing Ye Geng Chen Kui-Kui Lu Yin Chen Yu-Tao Chen Hong-Xing Pan Jiaping Yu Wenrong Yao Bao-Li Zhu Jianping Chen Yong Liu Cheng-Feng Qin Xiangxi Wang Feng-Cai Zhu | 2021 | National Science Review2021，8，8： | 4 |
| 4 | Efficacy and safety of single-bolus tenecteplase compared with front-loaded alteplase in Chinese patients with acute myocardial infarction显示文摘Background and Objective Previous study showed tenecteplase and alteplaxe were equovalent for 30-day mortality in the treatment of acute myocardial infarction. The purpose of this open-label,randomized,multi-center,angiographic trial was to assess the efficacy and safety of tenecteplase compared with alteplase in Chinese patients with acute myocardial infarction. Methods We recruited patients with acute ST-elevation myocardial infarction presenting within 6 hours of symptom onset from October,2002 to March,2004,in 5 hospitals in Beijing. After giving informed consent,patients were randomly assigned a single-bolus injection of tenecteplase(30-50 mg according to body weight) or front loaded alteplase(100 mg) ,and underwent coronary angiography at 90 min after starting the study drug. All patients received aspirin and heparin(target activated partial thromboplastin time 50-70 s) . The primary efficacy end point was the rate of TIMI grade 3 flow at 90 minutes. Other efficacy end points included TIMI grade 2/3 flow at 90 minutes. Safety end points included all stroke,intracranial hemorrhage(ICH) ,moderate/severe hemorrhage(except for ICH) ,all-cause mortality at 30-days,and major non-fatal cardiac events at 30 days. Results Overall 110 patients were eligible for statistical analysis,with 58 patients assigned to receive tenecteplase and 52 patients to alteplase. Tenecteplase produced a rate of TIMI grade 3 flow at 90 minutes after the start of thrombolysis(68.4%) similar to that of alteplase(66.7%,P=1.0) ;the rates of TIMI grade 2 or 3 were similar for patients treated with tenecteplase versus alteplase(89.5% versus 80.4%,respectively,P=0.278) . At 30 days,rates for all strokes were similar for the two groups(5.17% for tenecteplase and 1.92% for alteplase,P=0.62) ;rates of ICH were 3.45% and 1.92%(tenecteplase and rt-PA,P=1.00) respectively. The rate of moderate/severe hemorrhage was 8.62% with tenecteplase and 5.77% with alteplase(P=0.72) ;total mortality was almost identical in the two groups(13.8% versus 9.6%,respectively,P=0.565) while the rates of non-fatal cardiac complications were 10.35% and 11.54%(tenecteplase and alteplase,P=1.0) . Conclusions The efficacy of a single-bolus,weight-adjusted tenecteplase fibrinolytic regimen is equivalent to front-loaded alteplase in terms of the rates of TIMI grade 3 flow,and TIMI 2 or 3 flow,but the 30-day mortality and ICH in both groups was so high that the use of tenecteplase is not permitted in China. These negative safety results might be due to the high rate of percutaneous coronary intervention(PCI) and high dose of bolus heparin and suboptimal concomitant medical therapy during hospitalization,so further studies are needed to confirm the safety for tenecteplase in Chinese patients. | Feng Liang Dayi Hu Xubo Shi Mingshu Gao Jiaping Wei Hong Zhao Lei Wang Sanqing Jia Hongyu Wang Ruhuai Liu Yundai Chen Yanling Lu | 2007 | Journal of Geriatric Cardiology2007，4，3： | 1 |

| 9 | THE SIGNIFICANCE OF THE GREAT WALL AS A GEOGRAPHIC BOUNDARY显示文摘The Great Wall is not only the symbol of the ancient Chinese culture but also an actual and significant geographic boundary. The arrangements of the wall in past dynasties are based on physiographic conditions, and are just consistent with the demarcation line between semi-humid and arid climates in the country. Therefore,the Great Wall becomes an indicator of the demarcation line between the two areas.The extension and retreat of the wall generally reflect the expansion and shrinkage of farming and animal husbandry areas. From the viewpoint of political geography, the Great Wall can be regarded as the balance belt of 'forces' where the political powers of different nationalities histoncally stood facing each other and had repeated trials of strength. On one hand, the man-made wall of 10,000 li had the function of separating two political units, to some extent, the extension and retreat of the wall reflect the changes of relative strength of the two sides. On the other hand,the conflicts of the advanced and backward forces objectively promoted the economic and cultural exchanges as well as the national assimilation. Today, the Great Wall has lost its function of military works for territorial expansion and defense, but it is still the significant indicator as a geographic boundary and a sensitive area for many geographic elements. | Feng Jiaping Cheng Liansheng Xu Zhenpu(Dept. of Geography, Beijing Normal University, Beijing 1000875 People’s Republic of China ) | 1996 | Journal of Geographical Sciences1996，6，2： | 0 |
| 10 | Organophosphine ligand derived sandwich-structural electrocatalyst for oxygen evolution reaction显示文摘The synchronous construction of metal phosphate and phosphorus-doped carbon structures is of great significance to innovate the design,synthesis,and application of catalysts,as these phosphoruscontaining composite materials have shown a remarkable contribution to electrocatalysts.However,their preparation procedure generally involves using large amounts of excess phosphorus sources for phosphorization,which inevitably release poisonous PH_(3) or dangerous phosphorus vapor.Here,a strategy for in-situ formation of FePO_(4) embedded in P-doped carbon 2D nano film(FePO_(4)/PdC)is developed using a highly integrated precursor,which is a small molecular organophosphine ligand,1,1’bis(diphenylphosphine)ferrocene(DPPF).The multi-source precursor DPPF that contains Fe,P,and C is molecular-vapor-deposited on the nickel foam(NF)supported ZIF-67 nanosheets to obtain the composite catalyst,namely DPPF-500/ZIF-67/NF.FePO_(4)/PdC encapsulated the ZIF-67 derived Co/N-doped carbon matrix(Co NC)to form a sandwich structure FePO_(4)/PdC@CoNC.The constructed catalyst shows good performance for OER,requiring an overpotential of only 297 m V to deliver 600 m A/cm^(2) with a Tafel slope of 42.7 m V dec^(-1).DFT calculations demonstrate that the synergistic effects between the metal active center and P-doped carbon film reduce the energy barriers and improve electron transport.This method of constructing P-containing catalysts overcomes the demand for additional P sources to realize eco-friendly fabrication and yields a unique structure with good catalytic activity. | Zejun Sun Wenjuan Xu Liutao Guo Qiang Han Jianyi Gao Jiaping Wang Yanru Feng Chengrui Li Qionglin Liang Hong-bin Sun Yang Yang | 2022 | Journal of Energy Chemistry2022，31，7： | 0 |
