| 1 | Prevalence and clinical significance of pathogenic germline BRCA1/2 mutations in Chinese non-small cell lung cancer patients显示文摘Objective: Germline alterations in the breast cancer susceptibility genes type 1 and 2, BRCA1 and BRCA2, predispose individuals to hereditary cancers, including breast, ovarian, prostate, pancreatic, and stomach cancers.Accumulating evidence suggests inherited genetic susceptibility to lung cancer.The present study aimed to survey the prevalence of pathogenic germline BRCA mutations(gBRCAm) and explore the potential association between gBRCAm and disease onset in Chinese advanced non-small cell lung cancer(NSCLC) patients.Methods: A total of 6,220 NSCLC patients were screened using capture-based ultra-deep targeted sequencing to identify patients harboring germline BRCA1/2 mutations.Results: Out of the 6,220 patients screened, 1.03%(64/6,220) of the patients harbored the pathogenic gB RCAm, with BRCA2 mutations being the most predominant mutations(49/64, 76.5%).Patients who developed NSCLC before 50 years of age were more likely to carry gBRCAm(P = 0.036).Among the patients harboring classic lung cancer driver mutations, those with concurrent gBRCAm were significantly younger than those harboring the wild-type gBRCA(P = 0.029).By contrast, the age of patients with or without concurrent gBRCAm was comparable to those of patients without the driver mutations(P = 0.972).In addition, we identified EGFR-mutant patients with concurrent gBRCAm who showed comparable progression-free survival but significantly longer overall survival(P = 0.002) compared to EGFR-mutant patients with wild-type germline BRCA.Conclusions: Overall, our study is the largest survey of the prevalence of pathogenic gBRCAm in advanced Chinese NSCLC patients.Results suggested a lack of association between germline BRCA status and treatment outcome of EGFR-TKI.In addition,results showed a positive correlation between pathogenic gB RCAm and an early onset of NSCLC. | Xingsheng Hu Dongyong Yang Yalun Li Li Li Yan Wang Peng Chen Song Xu Xingxiang Pu Wei Zhu Pengbo Deng Junyi Ye Hanhan Zhang Analyn Lizaso Hao Liu Xinru Mao Hai Huang Qian Chu Chengping Hu | 2019 | Cancer Biology & Medicine2019，16，3： | 4 |
| 2 | Quantum dots assisted in vivo two-photon microscopy with NIR-Ⅱemission显示文摘With the advantages of high resolution and deep penetration depth,two-photon excited NIR-Ⅱ(900–1880 nm)fluorescence(2PF)microscopic bioimaging is promising.However,due to the lack of imaging systems and suitable probes,few such works,to our best knowledge,were demonstrated utilizing NIR-II excitation and NIR-Ⅱfluorescence simultaneously.Herein,we used aqueously dispersible Pb S/Cd S quantum dots with bright NIR-II fluorescence as the contrast agents.Under the excitation of a 1550 nm femtosecond(fs)laser,they emitted bright 2 PF in the NIR-Ⅱregion.Moreover,a 2PF lifetime imaging microscopic(2PFLIM)system was implemented,and in vivo 2PFLIM images of mouse brain blood vessels were obtained for the first time to our best knowledge.To improve imaging speed,an in vivo two-photon fluorescence microscopy(2 PFM)system based on an In Ga As camera was implemented,and in vivo 2PFM images of QDs-stained mouse brain blood vessels were obtained. | HUWEI NI YALUN WANG TAO TANG WENBIN YU DONGYU LI MUBIN HE RUNZE CHEN MINGXI ZHANG JUN QIAN | 2022 | Photonics Research2022，10，1： | 3 |
| 3 | Immunotherapy in non-small cell lung cancer:rationale,recent advances and future perspectives显示文摘Lung cancer,with non-small cell lung cancer(NSCLC)being the major type,is the second most commonmalignancy and the leading cause of cancer-related death globally.Immunotherapy,represented by immune checkpoint inhibitors(ICIs),has been one of the greatest advances in recent years for the treatment of solid tumors including NSCLC.However,not all NSCLC patients experience an effective response to immunotherapy with the established selection criteria of programmed death ligand 1(PD-L1)and tumor mutational burden(TMB).Furthermore,a considerable proportion of patients experience unconventional responses,including pseudoprogression or hyperprogressive disease(HPD),immune-related toxicities,and primary or acquired resistance during the immunotherapy process.To better understand the immune response in NSCLC and provide reference for clinical decision-making,we herein review the rationale and recent advances in using immunotherapy to treat NSCLC.Moreover,we discuss the current challenges and future strategies of this approach to improve its efficacy and safety in treating NSCLC. | Wenxin Luo Zhoufeng Wang Ting Zhang Lan Yang Jinghong Xian Yalun Li Weimin Li | 2021 | Precision Clinical Medicine2021，4，4： | 2 |

| 5 | A case of large-cell neuroendocrine carcinoma harboring rare ALK fusion with initial response to the ALK inhibitor crizotinib and acquired F1174L mutation after resistance显示文摘A 51-year-old,male,non-smoker with a 3.4 cm mass in the right middle lobe was diagnosed with large cell neuroendocrine carcinoma(LCNEC).Fluorescence in situ hybridization revealed anaplastic lymphoma kinase(ALK)gene translocation,in agreement with the immunohistochemistry result obtained with use of ALK-Ventana.Radiographic examinations showed both bone and brain metastasis.After two cycles of chemotherapy consisting of etoposide and cisplatin,the patient achieved stable disease,and was subsequently switched to crizotinib.Both computed tomography and magnetic resonance imaging revealed partial response after 4 months of crizotinib,but progressed after treatment for 10 months,when several hard lymph nodes were palpable in the left supraclavicular fossa.Lymph node biopsy showed similar histology of tumor cells and targeted next-generation sequencing revealed ALK F1174L on exon 23 with two rare forms of ALK rearrangements.This case provides evidence of responsiveness of ALK inhibitors for a rare pattern of ALK-rearranged LCNEC,and suggests that F1174L,a common resistant mutation found in non-small-cell lung cancer,also causes crizotinib resistance in LCNEC. | Ye Wang Panwen Tian Weiya Wang Yalun Li Yu Wang Weimin Li | 2019 | Precision Clinical Medicine2019，2，1： | 1 |
| 6 | Somatic mutation contributing to clonal haematopoiesis is a risk factor of recurrent stroke in first-ever acute ischaemic stroke:a prospective cohort study显示文摘Background Somatic mutation contributes to clonal haematopoiesis of indeterminate potential(CHIP)is related to age and associated with a higher risk of stroke and atherosclerotic cardiovascular disease.Here,we investigated the prognostic significance of CHIP in a large first-ever acute ischaemic stroke(AIS)cohort and explored the underlying mechanisms.Methods We studied a prospective cohort of 6016 patients who had a first-ever AIS in China.Whole-genome sequencing was performed to identify CHIP.High-sensitivity C reactive protein(hs-CRP)levels above 3 mg/L at baseline were defined as hyperinflammation.Recurrent stroke during the 3-month follow-up was the primary outcome.Results Among the 6016 patients who had a first-ever AIS,with a median age was 62 years(IQR,54.0‒70.0),3.70%were identified as CHIP carriers.The most common mutations occurred in the DNMT3A(30.0%)and TET2(11.4%)genes.During a follow-up of 3 months,the presence of CHIP was associated with recurrent stroke(HR 1.62,95%CI 1.04 to 2.51,p=0.03),recurrent ischaemic stroke(HR 1.64,95%CI 1.04 to 2.58,p=0.03)and combined vascular events(HR 1.58,95%CI 1.02 to 2.44,p=0.04)after adjusting for hsCRP levels at baseline in patients who had a first-ever AIS.Subgroup analysis demonstrated that CHIP was only associated with recurrent stroke when patients under hyperinflammation(OR 3.10,95%CI 1.92 to 5.00,p<0.001)but not in those without hyperinflammation(OR 0.18,95%CI 0.03 to 1.04,p=0.06,Pinteraction=0.002).Conclusion Our results suggest that somatic mutations contributing to CHIP increase the risk of short-term recurrent stroke in patients who had a first-ever AIS.Hyperinflammation may be important in the relationship between CHIP and recurrent stroke. | Xin Qiu Yalun Dai Si Cheng Hong-Qiu Gu Yong Jiang Xia Meng Yilong Wang Xingquan Zhao Yingyu Jiang Zhe Xu Xinying Huang Meng Wang Tian Jie Lyu Yubo Wang Jiaxu Weng Lingyun Cui Yi Shangguan Hao Li Yongjun Wang Zixiao Li | 2023 | Stroke & Vascular Neurology2023，8，2： | 1 |

| 8 | Comparing T-and B-cell responses to COVID-19 vaccines across varied immune backgrounds显示文摘The emergence of adapted variants of the SARS-CoV-2 virus has led to a surge in breakthrough infections worldwide.A recent analysis of immune responses in people who received inactivated vaccines has revealed that individuals with no prior infection have limited resistance to Omicron and its sub-lineages,while those with previous infections exhibit a significant amount of neutralizing antibodies and memory B cells.However,specific T-cell responses remain largely unaffected by the mutations,indicating that T-cell-mediated cellular immunity can still provide protection.Moreover,the administration of a third dose of vaccine has resulted in a marked increase in the spectrum and duration of neutralizing antibodies and memory B cells in vivo,which has enhanced resistance to emerging variants such as BA.2.75 and BA.2.12.1.These results highlight the need to consider booster immunization for previously infected individuals and the development of novel vaccination strategies.The rapid spread of adapted variants of the SARS-CoV-2 virus presents a significant challenge to global health.The findings from this study underscore the importance of tailoring vaccination strategies based on individual immune backgrounds and the potential need for booster shots to combat emerging variants.Continued research and development are crucial to discovering new immunization strategies that will effectively protect public health against the evolving virus. | Zhen Cui Wenxin Luo Ruihong Chen Yalun Li Zhoufeng Wang Yong Liu Shuo Liu LeiLei Feng Zijing Jia Ruixin Cheng Jun Tang Weijin Huang Yanjun Zhang Huawen Liu Xiangxi Wang Weimin Li | 2023 | Signal Transduction and Targeted Therapy2023，8，6： | 0 |
| 9 | Revealing the atomic mechanism of diamond–iron interfacial reaction显示文摘Diamond,with ultrahigh hardness,high wear resistance,high thermal conductivity,and so forth,has attracted worldwide attention.However,researchers found emergent reactions at the interfaces between diamond and ferrous materials,which significantly affects the performance of diamond-based devices.Herein,combing experiments and theoretical calculations,taking diamond–iron(Fe)interface as a prototype,the counter-diffusion mechanism of Fe/carbon atoms has been established.Surprisingly,it is identified that Fe and diamond first form a coherent interface,and then Fe atoms diffuse into diamond and prefer the carbon vacancies sites.Meanwhile,the relaxed carbon atoms diffuse into the Fe lattice,forming Fe_(3)C.Moreover,graphite is observed at the Fe_(3)C surface when Fe_(3)C is over-saturated by carbon atoms.The present findings are expected to offer new insights into the atomic mechanism for diamondferrous material's interfacial reactions,benefiting diamond-based device applications. | Yalun Ku Kun Xu Longbin Yan Kuikui Zhang Dongsheng Song Xing Li Shunfang Li Shaobo Cheng Chongxin Shan | 2024 | Carbon Energy2024，6，3： | 0 |

| 11 | Curricular Robust Reinforcement Learning via GAN-Based Perturbation Through Continuously Scheduled Task Sequence显示文摘Reinforcement learning(RL),one of three branches of machine learning,aims for autonomous learning and is now greatly driving the artificial intelligence development,especially in autonomous distributed systems,such as cooperative Boston Dynamics robots.However,robust RL has been a challenging problem of reliable aspects due to the gap between laboratory simulation and real world.Existing efforts have been made to approach this problem,such as performing random environmental perturbations in the learning process.However,one cannot guarantee to train with a positive perturbation as bad ones might bring failures to RL.In this work,we treat robust RL as a multi-task RL problem,and propose a curricular robust RL approach.We first present a generative adversarial network(GAN)based task generation model to iteratively output new tasks at the appropriate level of difficulty for the current policy.Furthermore,with these progressive tasks,we can realize curricular learning and finally obtain a robust policy.Extensive experiments in multiple environments demonstrate that our method improves the training stability and is robust to differences in training/test conditions. | Yike Li Yunzhe Tian Endong Tong Wenjia Niu Yingxiao Xiang Tong Chen Yalun Wu Jiqiang Liu | 2023 | Tsinghua Science and Technology2023，28，1： | 0 |
| 12 | Parameter-independent error correction for potential measurements by reference electrode in lithium-ion batteries显示文摘The safety monitoring of lithium-ion batteries(LIBs) is of great significance for realizing all-climate and full-lifespan battery management. In-situ measurement of anode potential with implanted reference electrodes(REs) has proven to be effective to monitor and avoid the occurrence of severe side reactions like Li plating to ensure the safe and fast charging. However, the intrinsic measurement errors caused by local blocking effects, which also can be referred to as potential artefacts, are seldom taken into consideration in existing studies, yet they highly dominate the correctness of conclusions inferred from REs. In this study, aiming at exploring the physical origin of the measurement errors and ensure reliable potential monitoring, electrochemical and post-mortem tests are conducted using commercial pouch cells with implanted REs. Corresponding electrochemical model which describes the blocking effects, is established to validate the abnormal absence of lithium plating that predicted by measured anode potentials under various charging rates. Theoretical derivation is further presented to explain the error sources, which can be attributed to increased local liquid potential of the RE position. Most importantly, with the guidance of error analysis, a novel parameter-independent error correction method for RE measurements is proposed for the first time, which is proven to be adequate to estimate the real anode potentials and deduce the critical C-rate of Li plating with extra safety margin. After error correction, the resulting critical C-rates are all within the range of 0.55 ± 0.03 C, which is close to the C-rate of 0.6–0.7 C obtained from experiments. In addition, this error correction method can be performed conveniently with only some simple RE measurements of polarization voltages, totally independent of battery electrochemical and geometric parameters. This study provides highly practical error correction method for RE measurements in real LIBs, substantially facilitating the fast diagnosis and safety evaluation of Li plating during charging of LIBs. | Yalun Li Xinlei Gao Xuning Feng Xuebing Han Jiuyu Du Languang Lu Minggao Ouyang | 2022 | Journal of Energy Chemistry2022，31，4： | 0 |

| 14 | Experimental Study on the Effect of State of Charge on Failure Propagation Characteristics within Battery Modules显示文摘To investigate the effect of different states of charge(SOC)on the thermal runaway(TR)propagation behaviors within lithium-ion-batteries based energy storage modules,an experimental setup was developed to conduct failure propagation tests on battery modules at an SOC of 97%,85%,and 50%.The result indicates that an increase in the SOC of batteries can decrease the TR trigger temperature,making batteries trigger TR earlier and reducing the average failure propagation time between two adjacent cells.In addition,the failure propagation tests reveal that at higher SOCs,the TR reaction becomes more violent,the maximal reaction temperature is also much higher,and the damage to the battery module is severe.Compared to the battery module with 97%SOC,the TR trigger time of the battery module with 50%SOC was postponed by approximately 57.8%.Meanwhile,the average failure propagation time got prolonged by approximately 36.0%.Thus,this study can provide references for the thermal safety design of energy-storage battery modules. | Kuijie Li Yalun Li Xinyu Rui Yuancheng Cao Liyun Fan Xuning Feng | 2023 | Chinese Journal of Electrical Engineering2023，9，3： | 0 |
