| 1 | An analytical biomarker for treatment of patients with recurrent B-ALL after remission induced by infusion of anti-CD19 chimeric antigen receptor T(CAR-T) cells显示文摘Anti-CD19 chimeric antigen receptor-modified T(CAR-T-19) cells have emerged as a powerful targeted immunotherapy for B-cell lineage acute lymphoblastic leukemia with a remarkable clinical response in recent trials. Nonetheless, few data are available on the subsequent clinical monitoring and treatment of the patients, especially those with disease recurrence after CAR-T-19 cell infusion. Here, we analyzed three patients who survived after our phase I clinical trial and who were studied by means of biomarkers reflecting persistence of CAR-T-19 cells in vivo and predictive factors directing further treatment. One patient achieved 9-week sustained complete remission and subsequently received an allogeneic hematopoietic stem cell transplant. Another patient who showed relapse after 20 weeks without detectable leukemia in the cerebrospinal fluid after CAR-T-19 cell treatment was able to achieve a morphological remission under the influence of stand-alone low-dose chemotherapeutic agents. The third patient gradually developed extensive extramedullary involvement in tissues with scarce immune-cell infiltration during a long period of hematopoietic remission after CAR-T-19 cell therapy. Long-term and discontinuous increases in serum cytokines(mainly interleukin 6 and C-reactive protein) were identified in two patients(Nos. 1 and 6) even though only a low copy number of CAR molecules could be detected in their peripheral blood. This finding was suggestive of persistent functional activity of CAR-T-19 cells. Combined analyses of laboratory biomarkers with their clinical manifestations before and after salvage treatment showed that the persistent immunosurveillance mediated by CAR-T-19 cells would inevitably potentiate the leukemia-killing effectiveness of subsequent chemotherapy in patients who showed relapse after CAR-T-19-induced remission. | Yajing Zhang Wenying Zhang Hanren Dai Yao Wang Fengxia Shi Chunmeng Wang Yelei Guo Yang Liu Meixia Chen Kaichao Feng Yan Zhang Chuanjie Liu Qingming Yang Suxia Li Weidong Han | 2016 | Science China(Life Sciences)2016，59，4： | 6 |
| 2 | Quantitative prediction of shale gas sweet spots based on seismic data in Lower Silurian Longmaxi Formation,Weiyuan area,Sichuan Basin,SW China显示文摘Sweet spots in the shale reservoirs of the Lower Silurian Longmaxi Formation in Weiyuan 201 Block of Sichuan Basin were predicted quantitatively using seismic data and fuzzy optimization method. First, based on seismic and rock physics analysis, the rock physics characteristics of the reservoirs were determined, and elastic parameters sensitive to shale reservoirs with high gas content were selected. Second, data volumes with high precision of the elastic parameters were obtained from pre-stack simultaneous inversion. The horizontal distribution of key parameters for shale gas evaluation were calculated based on the results of rock physics analysis. Then, the fuzzy evaluation equation was established by fuzzy optimization method with test and logging data of horizontal wells with similar operation conditions. key parameters affecting the productivity of horizontal wells were sorted out and the weights of them in the sweet spots quantitative prediction were worked out by fuzzy optimization to set up a sweet spots evaluation system. Three classes of shale gas reservoirs which including two kinds of sweet spots were predicted with the above procedure, and the sweet spots have been predicted quantitatively by combining the above prediction results with the testing production. The testing results of 7 verification wells proved the reliability of the prediction results. | ZENG Qingcai CHEN Sheng HE Pei YANG Qing GUO Xiaolong CHEN Peng DAI Chunmeng LI Xuan GAI Shaohua DENG Yu HOU Huaxing | 2018 | Petroleum Exploration and Development2018，45，3： | 2 |
| 3 | The model of cytokine release syndrome in CAR T-cell treatment for B-cell non-Hodgkin lymphoma显示文摘Chimeric antigen receptor T(CAR T)cell therapy has demonstrated efficacy in the treatment of haematologic malignancies.However,the accompanying adverse events,the most common of which is cytokine release syndrome(CRS),substantially limit its wide application.Due to its unique physiological characteristics,CRS in CAR T-cell treatment for B-cell non-Hodgkin lymphoma(BNHL)may exhibit some special features.Although existing guidelines had greatly promoted the recognition and management of CRS,many recommendations are not fully applicable to B-NHL.Therefore,it is imperative to identify responses that are specific to CRS observed following CAR T treatment for B-NHL.Based on underlying biological processes and known pathophysiological mechanisms,we tentatively propose a new model to illustrate the occurrence and evolution of CAR T-cell-therapy-related CRS in BNHL.In this model,tumour burden and bone marrow suppression are considered determinants of CRS.Novel phenomena after CAR T-cell infusion(such as local inflammatory response)are further identified.The proposed model will help us better understand the basic biology of CRS and recognize and manage it more rationally. | Jianshu Wei Yang Liu Chunmeng Wang Yajing Zhang Chuan Tong Guanghai Dai Wei Wang John E.J.Rasko J.Joseph Melenhorst Wenbin Qian Aibin Liang Weidong Han | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 2 |
| 4 | PC4 serves as a negative regulator of skin wound healing in mice显示文摘Background:Human positive cofactor 4(PC4)was initially characterized as a multifunctional transcriptional cofactor,but its role in skin wound healing is still unclear.The purpose of this study was to explore the role of PC4 in skin wound healing through PC4 knock-in mouse model.Methods:A PC4 knock-in mouse model(PC4^(+/+))with a dorsal full-thickness wound was used to investigate the biological functions of PC4 in skin wound healing.Quantitative PCR,Western blot analysis and immunohistochemistry were performed to evaluate the expression of PC4;Sirius red staining and immunofluorescence were performed to explore the change of collagen deposition and angiogenesis.Proliferation and apoptosis were detected using Ki67 staining and TUNEL assay.Primary dermal fibroblasts were isolated from mouse skin to perform cell scratch experiments,cck-8 assay and colony formation assay.Results:The PC4^(+/+)mice were fertile and did not display overt abnormalities but showed an obvious delay in cutaneous healing of dorsal skin.Histological staining showed insufficient re-epithelialization,decreased angiogenesis and collagen deposition,increased apoptosis and decreased cell proliferation in PC4^(+/+)skin.Our data also showed decreased migration rate and proliferation ability in cultured primary fibroblasts from PC4^(+/+)mice in vitro.Conclusions:This study suggests that PC4 might serve as a negative regulator of skin wound healing in mice. | Fengying Liao Long Chen Peng Luo Zhongyong Jiang Zelin Chen Ziwen Wang Chi Zhang Yu Wang JintaoHe Qing Wang Yawei Wang Lang Liu Yu Huang Huilan Wang Qingzhi Jiang Min Luo YiboGan Yunsheng Liu Yang Wang Jie Wu Wentao Xie Zhuo Cheng Yali Dai Jialun Li Zujuan Liu Fan Yang Chunmeng Shi | 2020 | Burns & Trauma2020，8，1： | 1 |
| 5 | Therapeutic implications of exosomes in the treatment of radiation injury显示文摘Radiotherapy is one of the main cancer treatments,but it may damage normal tissue and cause various side effects.At present,radioprotective agents used in clinics have side effects such as nausea,vomiting,diarrhea and hypotension,which limit their clinical application.It has been found that exosomes play an indispensable role in radiation injury.Exosomes are lipid bilayer vesicles that carry various bioactive substances,such as proteins,lipids and microRNA(miRNA),that play a key role in cell-to-cell communication and affect tissue injury and repair.In addition,studies have shown that radiation can increase the uptake of exosomes in cells and affect the composition and secretion of exosomes.Here,we review the existing studies and discuss the effects of radiation on exosomes and the role of exosomes in radiation injury,aiming to provide new insights for the treatment of radiation injury. | Shijie Dai Yuzhong Wen Peng Luo Le Ma Yunsheng Liu Junhua Ai Chunmeng Shi | 2022 | Burns & Trauma2022，10，1： | 0 |
| 6 | Crystalline Germanium-Dipyrromethene Radicals:from a Delocalized Neutral to a Localized Cation显示文摘Both dipyrromethene complexes and radicals of heavier main group elements have been of high interest.However,cationic germanium radicals and dipyrromethene-based radicals of heavier main group elements are still escaped to be isolated.Herein,we report the isolation and full characterization of a neutral Ge(I)-masked dipyrromethene-based radical 3 and the first cationic Ge(III)-centered radical 5^(·+)as stable crystalline solids.3 behaves as a germanium(I)radical in its reaction with diphenyl disulfide to form the Ge-S bond,although X-ray crystallographic,EPR spectroscopic,computational studies revealed that the unpaired electron of 3 is mainly delocalized over the C_(9)N_(2)Ge backbone and the allylic radical character is also significant in 3.In contrast to 3,the spin density of 5^(·+)is mainly localized at the Ge center with minor contribution from the dipyrromethene ligand.Moreover,reduction of 5^(·+)with potassium graphite quantitatively regenerates 5,illustrating a reversible one-electron redox pair. | Yuyang Dai Manling Bao Wenjuan Wang Zhuofeng Xie Chunmeng Liu Yuanting Su | 2022 | Chinese Journal of Chemistry2022，40，20： | 0 |
| 7 | Isolable Bis-BN-Based Analogues of Müller's Hydrocarbon显示文摘Müller's hydrocarbon and its analogues are classical examples of Kekulé diradicaloids and have gained great attention.However,because of their high reactivities,their isolation and structural characterizations are still challenging.Herein,we report the isolation of two bis-BN-based analogues of Müller's hydrocarbon (1 and 2) as crystalline solids in moderate yields.Experimental results and theoretical studies demonstrated that compound 1 possessing the terminal 1,3,2-diazaboryl groups is an open-shell singlet diradicaloid,which is in contrast to the closed-shell singlet ground states of the bis-BN-based analogues of Thiele's and Chichibabin's hydrocarbons with the same terminal groups,illustrating the strong influence of the central linkers on the ground state.Additionally,the replacement of the terminal 1,3,2-diazaboryl groups in 1 with the bis(2,4,6-triisopropylphenyl)boryl groups affords 2 with higher diradical character and a smaller singlet-triplet energy gap. | Sha Xu Zhuofeng Xie Yuyang Dai Xiaona Liu Qidi Bao Chunmeng Liu Yuanting Su | 2023 | Chinese Journal of Chemistry2023，41，23： | 0 |
