| 1 | Clinical study of ultrasound and microbubbles for enhancing chemotherapeutic sensitivity of malignant tumors in digestive system显示文摘Objective: To explore the safety of ultrasound and microbubbles for enhancing the chemotherapeutic sensitivity of malignant tumors in the digestive system in a clinical trial, as well as its efficacy.Methods: From October 2014 to June 2016, twelve patients volunteered to participate in this study. Eleven patients had hepatic metastases from tumors of the digestive system, and one patient had pancreatic carcinoma.According to the mechanical index(MI) in the ultrasound field, patients were classified into four groups with MIs of 0.4, 0.6, 0.8 and 1.0. Within half an hour after chemotherapy, patients underwent ultrasound scanning with ultrasound microbubbles(SonoVue) to enhance the efficacy of chemotherapy. All adverse reactions were recorded and were classified in 4 grades according to the Common Terminology Criteria for Adverse Events version 4.03(CTCAE V4.03). Tumor responses were evaluated by the Response Evaluation Criteria in Solid Tumors version1.1 criteria. All the patients were followed up until progression.Results: All the adverse reactions recorded were level 1 or level 2. No local pain occurred in any of the patients.Among all the adverse reactions, fever might be related to the treatment with ultrasound combined with microbubbles. Six patients had stable disease(SD), and one patient had a partial response(PR) after the first cycle of treatment. At the end of follow-up, tumor progression was restricted to the original sites, and no new lesions had appeared.Conclusions: Our preliminary data showed the potential role of a combined treatment with ultrasound and microbubbles in enhancing the chemotherapeutic sensitivity of malignant tumors of the digestive system. This technique is safe when the MI is no greater than 1.0. | Yanjie Wang Yan Li Kun Yan Lin Shen Wei Yang Jifang Gong Ke Ding | 2018 | Chinese Journal of Cancer Research2018,30,5: | 8 |
| 2 | Aneuploidy of chromosome 8 in circulating tumor cells correlates with prognosis in patients with advanced gastric cancer显示文摘Objective: Previous work indicated that aneuploidy of chromosome 8 in circulating tumor cells(CTCs)correlated with therapeutic efficacy for advanced gastric cancer(AGC) patients. In this follow-up study performed on the same population of AGC patients, we investigated whether and how aneuploidy of chromosome 8 in CTCs correlates with patients' clinical prognosis.Methods: The prospective study was performed on 31 patients with newly diagnosed AGC. Previously established integrated subtraction enrichment(SE) and immunostaining-fluorescence in situ hybridization(i FISH)platform was applied to identify, enumerate and characterize CTCs. Quantification of CTCs and analysis of their aneuploidy of chromosome 8 were performed on patients before and after therapy.Results: CTCs were measured in 93.5% of AGC patients, and two CTC subtypes with diverse threshold values were identified, multiploid CTCs with the threshold of ≥2 per 7.5 m L and multiploid plus triploid CTCs with the threshold of ≥4, which were found to significantly correlate with poor progression-free survival(PFS) and overall survival(OS). In particular, patients with ≥10% increased multiploid CTCs after an initial 6 weeks of therapy had poor PFS and OS, whereas improved PFS and OS were observed on those who had ≥10% decreased multiploid CTCs. After adjusting for clinically significant factors, ≥10% increased post-therapy multiploid CTCs was the only independent predictor of PFS and OS.Conclusions: Aneuploidy of CTCs correlates with prognosis of AGC patients. Quantitative comparison monitoring multiploid CTCs before and after therapy may help predict improved or inferior prognosis and chemoresistance. | Yilin Li Xiaotian Zhang Jifang Gong Qiyue Zhang Jing Gao Yanshuo Cao Daisy Dandan Wang Peter Ping Lin Lin Shen | 2016 | Chinese Journal of Cancer Research2016,28,6: | 7 |
| 3 | Clinicopathologic features and treatment efficacy of Chinese patients with BRAF-mutated metastatic colorectal cancer: a retrospective observational study显示文摘Background: The prognostic role of the V600 E mutation of v-raf murine sarcoma viral oncogene homolog B1(BRAF)in metastatic colorectal cancer(mCRC) is well established, but the therapeutic regimen targeting this disease is lacking. This study aimed to analyze the clinicopathologic features of and treatment efficacy of commonly used regimens on BRAF-mutated mCRCs.Methods: We collected and reviewed the medical records of mCRC patients treated at Peking University Cancer Hospital & Institute(Beijing, China) between July 2011 and July 2016. Kirsten rat sarcoma viral oncogene homolog(KRAS),neuroblastoma RAS viral oncogene homolog(NRAS), and BRAF mutational status was assayed using direct sequencing. The details of clinicopathologic characteristics of patients and their responses to FOLFOXIRI regimen or standard therapy were obtained by reviewing the medical records. The progression-free survival(PFS) and overall survival(OS)were assessed using Kaplan-Meier analysis and compared using the log-rank test.Results: Of 1694 patients studied, 75 had BRAF exon 15 mutations. Of these 75 patients, 71 had V600 E mutation, 1 had D594 G mutation, 2 had K601 E mutation, and 1 had a novel T599_V600 insAGA alteration. No patients had KRAS or NRAS mutations. Of 63 patients with BRAFV600 E-mutated mCRC and sufficient clinical data, 27(42.9%) had right-sided colon tumors, 19(30.2%) had left-sided colon tumors, and 17(26.9%) had rectal tumors; 26(41.3%) had peritoneal metastases, and 50(79.4%) had distant lymph node metastases.The patients with BRAF K601 E-and T599_V600 insAGA-mutated tumors had similar clinicopathologic features to those with BRAFV600 E-mutated tumors. Patients with the BRAFV600 E mutation benefited more from FOLFOXIRI regimen compared with patients who underwent standard therapy(overall response rate 83.3% vs. 14.0%; median PFS 6.4 months vs. 2.8 months, P = 0.220; median OS11.0 months vs. 6.9 months, P = 0.048).Conclusions: BRAFV600 E mutations were commonly identified in right-sided tumors and showed a high incidence of peritoneal and distant lymph nodes metastases.This subtype of mCRC was characterized by short OS and unique patterns of metastasis. Compared with standard treatment regimens, the FOLFOXIRI regimen had acceptable and manageable toxicities and favorable efficacy on patients with BRAF-mutated mCRC. | Xicheng Wang Qing Wei Jing Gao Jian Li Jie Li Jifang Gong Yanyan Li Lin Shen | 2017 | Chinese Journal of Cancer2017,36,11: | 6 |
| 4 | Dark matter direct search sensitivity of the PandaX-4T experiment显示文摘The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2 at a dark matter mass of 40 Ge V/c^2. | HongGuang Zhang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui BinBin Dong DeQing Fang ChangBo Fu Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo ZhiFan Guo Ke Han ChangDa He ShengMing He Di Huang XingTao Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju ShaoLi Li Yao Li Heng Lin HuaXuan Liu JiangLai Liu YuGang Ma YaJun Mao KaiXiang Ni JinHua Ning XiangXiang Ren Fang Shi AnDi Tan AnQing Wang Cheng Wang HongWei Wang Meng Wang QiuHong Wang SiGuang Wang XiuLi Wang XuMing Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu JuMin Yuan JianFeng Yue Dan Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou | 2019 | Science China(Physics,Mechanics & Astronomy)2019,62,3: | 6 |
| 5 | First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region. | Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu | 2021 | Science China(Physics,Mechanics & Astronomy)2021,64,8: | 3 |
| 6 | First results on ^(76)Ge neutrinoless double beta decay from CDEX-1 experiment显示文摘We report the first results on ^(76)Ge neutrinoless double beta decay from stage one of the China dark-matter experiment(CDEX).A p-type point-contact high-purity germanium detector with a mass of 994 g has been installed to detect neutrinoless double beta decay events, as well as to directly detect dark matter particles. An exposure of 304 kg d has been analyzed over a wide spectral band from 500 keV to 3 MeV. The average event rate obtained was about 0.012 counts per keV per kg per day over the 2.039 MeV energy range. The half-life of ^(76)Ge neutrinoless double beta decay derived based on this result is T^(0ν)1/2>6.4×10^(22) yr(90% C.L.). An upper limit on the effective Majorana-neutrino mass of 5.0 eV has been achieved. | Li Wang Qian Yue KeJun Kang JianPing Cheng YuanJing Li TszKing Henry Wong ShinTed Lin JianPing Chang JingHan Chen QingHao Chen YunHua Chen Zhi Deng Qiang Du Hui Gong Li He QingJu He JinWei Hu HanXiong Huang TengRui Huang LiPing Jia Hao Jiang HauBin Li Hong Li JianMin Li Jin Li Jun Li Xia Li XueQian Li YuLan Li FongKay Lin ShuKui Liu Hao Ma JingLu Ma XingYu Pan Jie Ren XiChao Ruan ManBin Shen Vivek Sharma Lakhwinder Singh Manoj Kumar Singh Manoj Kumar Singh Arun Kumar Soma ChangJian Tang WeiYou Tang ChaoHsiung Tseng JiMin Wang Qing Wang ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue LiTao Yang SongWei Yang Nan Yi ChunXu Yu HaiJun Yu WeiHe Zeng XiongHui Zeng Zhi Zeng Lan Zhang YunHua Zhang MingGang Zhao Wei Zhao JiFang Zhou ZuYing Zhou JingJun Zhu WeiBin Zhu ZhongHua Zhu | 2017 | Science China(Physics,Mechanics & Astronomy)2017,60,7: | 3 |
| 7 | 重组人白细胞介素-11治疗消化道肿瘤化疗后血小板减少症的临床研究(英文)显示文摘Objective: To evaluate the efficacy and safety of recombinant human interleukin-11 (rhIL-11) for the chemo-therapy-induced thrombocytopenia in patients with gastrointestinal cancer. Methods: It was an opened and non-randomized controlled clinical study. When the platelet counts was under 75 × 109 /L after chemotherapy, rhIL-11 was administered 25 μg/(kg?d) as a daily SC injection last for 7-14 days, or discontinued when platelet counts ≥ 100 × 109 /L. Results: Seventy-six patients were enrolled into this study. The treatment group and the control group had thirty-eight cases, respectively. The mean recovery time to PLT ≥ 100 × 109 /L was 8.1 days in treatment group, while in control group was 12.2 days (P < 0.01). Moreover, the mean recovery time from PLT ≤ 50 × 109 /L to ≥ 100 × 109 /L was 8.9 days in treatment group, while in control group was 12.9 days (P < 0.05). There was a statistical difference between the two groups. Major side effects included edema, fever, articular muscle soreness, but they were all mild and well tolerable. Conclusion: rhIL-11 can be safely and effectively used for the treatment of chemotherapy-induced thrombocytopenia in patients with gastrointestinal cancer. | Jie Li Lin Shen Yan Li Xiaodong Zhang Jian Li Jifang Gong Wei Deng | 2007 | The Chinese-German Journal of Clinical Oncology2007,6,5: | 1 |

| 9 | Polarization-robust mid-infrared carpet cloak with minimized lateral shift显示文摘With the advent and rapid development of the transformation optics and metamaterials,invisibility cloaks have captivated much attention in recent years.While most cloaking schemes suffer from limited bandwidth,the carpet cloak,which can hide an object on a reflecting plane,can operate over a broadband frequency range.However,the carpet cloaks experimentally realized thus far still have several limitations.For example,the quasi-conformal mapping carpet cloak leads to a lateral shift of the reflected light ray,while the birefringent carpet cloak only works for a specific polarization.In this work,we propose a conformal transformation scheme to tackle these two problems simultaneously.As an example,we design a mid-infrared carpet cloak in a silicon platform and demonstrate its polarization-insensitive property as well as the minimized lateral shift over a broad frequency band from 24 to 28.3 THz. | YAO HUANG JINGJING ZHANG JINHUI ZHOU BO QIANG ZHENGJI XU LIN LIU JIFANG TAO NICOLAS KOSSOWSKI QIJIE WANG YU LUO | 2021 | Photonics Research2021,9,6: | 1 |

| 11 | An improved evaluation of the neutron background in the PandaX-Ⅱ experiment显示文摘In dark matter direct detection experiments,neutron is a serious source of background,which can mimic the dark matter-nucleus scattering signals.In this paper,we present an improved evaluation of the neutron background in the PandaX-II dark matter experiment by a novel approach.Instead of fully relying on the Monte Carlo simulation,the overall neutron background is determined from the neutron-induced high energy signals in the data.In addition,the probability of producing a dark-matter-like background per neutron is evaluated with a complete Monte Carlo generator,where the correlated emission of neutron(s)andγ(s)in the(α,n)reactions and spontaneous fissions is taken into consideration.With this method,the neutron backgrounds in the Run 9(26-ton-day)and Run 10(28-ton-day)data sets of PandaX-II are estimated to be(0.66±0.24)and(0.47±0.25)events,respectively. | QiuHong Wang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui YingJie Fan DeQing Fang ChangBo Fu LiSheng Geng Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo Ke Han ChangDa He Di Huang Yan Huang YanLin Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju YiHui Lai Kun Liang HuaXuan Liu JiangLai Liu WenBo Ma YuGang Ma YaJun Mao Yue Meng Parinya Namwongsa KaiXiang Ni JinHua Ning XuYang Ning XiangXiang Ren ChangSong Shang Lin Si AnDi Tan AnQing Wang HongWei Wang Meng Wang SiGuang Wang XiuLi Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu Jumin Yuan Dan Zhang HongGuang Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou | 2020 | Science China(Physics,Mechanics & Astronomy)2020,63,3: | 0 |
| 12 | Constraining self-interacting dark matter with the full dataset of PandaX-II显示文摘Self-interacting dark matter(SIDM)is a leading candidate proposed to solve discrepancies between predictions of the prevailing cold dark matter theory and observations of galaxies.Many SIDM models predict the existence of a light force carrier that mediates strong dark matter self-interactions.If the mediator couples to the standard model particles,it could produce characteristic signals in dark matter direct detection experiments.We report searches for signals of SIDM models with a light mediator using the full dataset of the PandaX-II experiment,basing on a total exposure of 132 tonne-days.No significant excess over background is found,and our likelihood analysis leads to a strong upper limit on the dark matter-nucleon coupling strength.We further combine the PandaX-II constraints and those from observations of the light element abundances in the early universe,and show that direct detection and cosmological probes can provide complementary constraints on dark matter models with a light mediator. | Jijun Yang Abdusalam Abdukerim Wei Chen Xun Chen Yunhua Chen Chen Cheng Xiangyi Cui Yingjie Fan Deqing Fang Changbo Fu Mengting Fu Lisheng Geng Karl Giboni Linhui Gu Xuyuan Guo Ke Han Changda He Shengming He Di Huang Yan Huang Ran Huo Yanlin Huang Zhou Huang Xiangdong Ji Yonglin Ju Shuaijie Li Qing Lin Huaxuan Liu Jianglai Liu Xiaoying Lu Wenbo Ma Yugang Ma Yajun Mao Yue Meng Nasir Shaheed Kaixiang Ni Jinhua Ning Xuyang Ning Xiangxiang Ren Changsong Shang Guofang Shen Lin Si Andi Tan Anqing Wang Hongwei Wang Meng Wang QiuHong Wang Siguang Wang Wei Wang Xiuli Wang Zhou Wang Mengmeng Wu Shiyong Wu Weihao Wu Jingkai Xia Mengjiao Xiao Xiang Xiao Pengwei Xie Binbin Yan Yong Yang Chunxu Yu Hai-Bo Yu Jumin Yuan Ying Yuan Xinning Zeng Dan Zhang Tao Zhang Li Zhao Qibin Zheng Jifang Zhou Ning Zhou Xiaopeng Zhou | 2021 | Science China(Physics,Mechanics & Astronomy)2021,64,11: | 0 |

| 14 | A flexible artificial solid-electrolyte interlayer supported by compactness-tailored carbon nanotube network for dendrite-free lithium metal anode显示文摘A dendrite-free lithium metal anode requires a stable interface designed for efficient and reversible lithium plating and stripping. In this work, we have devised a mechanically flexible artificial Li_(3)N solid-electrolyte interlayer supported by a dual-layer compactness-tailored carbon nanotube fiber network. The more compact side of the network ensures a full coverage of Li_(3)N, which prevents the reaction between electrolyte and lithium. The other side, with sparsely distributed nanotube fibers, provides mechanical flexibility for the film, and induces three-dimensional lithium deposition along its structure without any dendrite formation. The resulting full cell with NCM811 cathode has a high capacity retention of 95.1% for 160 cycles compared with less than 80% for the control. | Haowen Liu Jifang Zhang Yang Liu Yang Wei Shuaiyang Ren Ludi Pan Yi Su Jianhua Xiao Haiyan Fan Yitao Lin Yipeng Su Yuegang Zhang | 2022 | Journal of Energy Chemistry2022,31,6: | 0 |
| 15 | New design method of unequal taper thread(UTT)pairs and its application in API NC38 thread improvement显示文摘API standard threads are the most commonly used thread configurations for drill pipe joints in the petroleum industry.Recently with the increasing application of horizontal wells and extended-reach wells in drilling engineering,drill pipe joint threads are subjected to complex loads,and drill pipe joint thread breakage accidents occur frequently.The API NC38 threaded pair used in the SU36-8-4H2 well suffered a fracture accident.Macroscopic analysis found that the fracture sites were located near the root of the first engagement pin-thread where the stress was greatest.Therefore,it is necessary to find an alternative method to reduce the largest stress of NC38 threads.Then,a new design method of unequal taper thread(UTT)pairs is proposed that the taper of pin thread,slightly smaller than the taper of matched-box thread,is not equal to one of box-thread.In the UTT pairs of API NC38 thread,the taper of box thread is kept as the standard taper of 1:6,but the taper of pin thread is,respectively,1:6.1(UTT-I),1:6.2(UTT-Ⅱ),1:6.3(UTT-Ⅲ)and 1:6.4(UTT-IV).The 3D finite element models of four UTT pairs and one standard pair based on NC38 thread were developed,and the mechanical properties of five thread pairs bearing such typical working loads as torque,axial compression,axial tension,bending moment,internal and external pressure,were analyzed.The results show that four UTT pairs are superior to the standard pair of API NC38,and UTT-Ⅲ has the most performance in all of four UTT pairs.Compared with the standard pair of API NC38,UTT-Ⅲ pair can improve the bearing capacity such as torsion strength,compression strength,tensile strength,bending strength,strength against internal and external pressure,by 24.8%,13.2%,22%,9.99%and 14.2%,respectively.The new design method of UTT pair enhances the bearing capacity of API NC38 thread,and has been applied in Changqing Drilling Company of CNPC Chuanqing Drilling Engineering Company Limited.The UTT-thread pair method is not only applicable for API series threads to improve the connection performance,but also suitable for various non-API taper connection threads to promote existing working ability such as air tightness,stress corrosion resistance,fatigue resistance et al. | Hangming Liu Yangye He Jifang Wan Lin Chen Xianzhong Yi Song Hou Yanbin Wang Dongxu He Gang Li | 2023 | Petroleum2023,9,3: | 0 |
| 16 | Tailoring Mg^(2+)Solvation Structure in a Facile All-Inorganic[Mg_(x)Li_(y)Cl2_(x+y)·nTHF]Complex Electrolyte for High Rate and Long Cycle-Life Mg Battery显示文摘A high-performance all-inorganic magnesium-lithium chloride complex(MLCC)electrolyte is synthesized by a simple room-temperature reaction of LiCl with MgCl_(2) in tetrahydrofuran(THF)solvent.Molecular dynamics simulation,density functional theory calculation,Raman spectroscopy,and nuclear magnetic resonance spectroscopy reveal that the formation of[Mg_(x)Li_(y)Cl_(2x+y)·nTHF]complex solvation structure significantly lowers the coordination number of THF in the first solvation sheath of Mg^(2+),which significantly enhances its de-solvation kinetics.The MLCC electrolyte presents a stable electrochemical window up to 3.1 V(vs Mg/Mg^(2+))and enables reversible cycling of Mg metal deposition/stripping with an outstanding Coulombic efficiency up to 99%at current densities as high as 10 mA cm^(-2).Utilizing the MLCC electrolyte,a Mg/Mo_(6)S_(8) full cell can be cycled for over 10000 cycles with a superior capacity retention of 85 mA h g^(-1) under an ultrahigh rate of 50 C(1 C=128.8 mA g^(-1)).The facile synthesis of highperformance MLCC electrolyte provides a promising solution for future practical magnesium batteries. | Haiyan Fan Xinxin Zhang Yuxing Zhao Jianhua Xiao Hua Yuan Guang Wang Yitao Lin Jifang Zhang Ludi Pan Ting Pan Yang Liu Yuegang Zhang | 2023 | Energy & Environmental Materials2023,6,2: | 0 |
| 17 | Alterations in DNA damage response and repair genes as potential biomarkers for immune checkpoint blockade in gastrointestinal cancer显示文摘Objective:Immune checkpoint inhibitors(ICIs)have achieved remarkable results in cancer treatments.However,there is no effective predictive biomarker for gastrointestinal(GI)cancer.Methods:We conducted integrative analyses of the genomic and survival data of ICI-treated GI cancer patients from the Memorial Sloan Kettering Cancer Center cohort(MSK-GI,n=227),the Janjigian cohort(n=40),and the Peking University Cancer Hospital&Institute cohort(PUCH,n=80)to determine the possible associations between DNA damage response and repair(DDR)gene mutations and clinical outcomes.Data from The Cancer Genome Atlas database were analyzed to determine the possible correlations between DDR gene mutations and the tumor microenvironment.Results:In the MSK cohort,the presence of≥2 DDR gene mutations was correlated with prolonged overall survival(OS).The Janjigian and PUCH cohorts further confirmed that subgroups with≥2 DDR gene mutations displayed a prolonged OS and a higher durable clinical benefit.Furthermore,the DDR gene mutation load could be considered as an independent prognostic factor,and exhibited a potential predictive value for survival in GI cancer patients treated with ICIs.Mechanistically,we showed that the presence of≥2 DDR gene mutations was correlated with higher levels of tumor mutation burden,neoantigen,and T cell infiltration.Conclusions:The DDR gene mutation status was correlated with favorable clinical outcomes in GI cancer patients receiving ICIs,which could serve as a potential biomarker to guide patient selection for immunotherapy. | Yujiao Wang Xi Jiao Shuang Li Huan Chen Xin Wei Chang Liu Jifang Gong Xiaotian Zhang Xicheng Wang Zhi Peng Changsong Qi Zhenghang Wang Yanni Wang Na Zhuo Jianling Zou Henghui Zhang Jian Li Lin Shen Zhihao Lu | 2022 | Cancer Biology & Medicine2022,19,8: | 0 |
| 18 | Performances of a prototype point-contact germanium detector immersed in liquid nitrogen for light dark matter search显示文摘The CDEX-10 experiment searches for light weakly interacting massive particles, a form of dark matter, at the China Jinping Underground Laboratory, where approximately 10 kg of germanium detectors are arranged in an array and immersed in liquid nitrogen. Herein, we report on the experimental apparatus, detector characterization, and spectrum analysis of one prototype detector. Owing to the higher rise-time resolution of the CDEX-10 prototype detector as compared with CDEX-1 B, we identified the origin of an observed category of extremely fast events. For data analysis of the CDEX-10 prototype detector, we introduced and applied an improved bulk/surface event discrimination method. The results of the new method were compared to those of the CDEX-1 B spectrum. Both sets of results showed good consistency in the 0-12 ke Vee energy range, except for the 8.0 keV K-shell X-ray peak from the external copper. | Hao Jiang LiTao Yang Qian Yue KeJun Kang JianPing Cheng YuanJing Li Henry Tsz-King Wong M.A?artio?lu HaiPeng An JianPing Chang JingHan Chen YunHua Chen Zhi Deng Qiang Du Hui Gong Li He Jin Wei Hu QingDong Hu HanXiong Huang LiPing Jia HauBin Li Hong Li Jian Min Li Jin Li Xia Li XueQian Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu YuanYuan Liu ZhongZhi Liu Hao Ma JingLu Ma Hui Pan Jie Ren XiChao Ruan B.Sevda Vivek Sharma ManBin Shen Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang JiMin Wang Li Wang Qing Wang Yi Wang ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue SongWei Yang Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue XiongHui Zeng Ming Zeng Zhi Zeng FengShou Zhang YunHua Zhang MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu ZhongHua Zhu | 2019 | Science China(Physics,Mechanics & Astronomy)2019,62,3: | 0 |
| 19 | Abivertinib inhibits megakaryocyte differentiation and platelet biogenesis显示文摘Abivertinib,a third-generation tyrosine kinase inhibitor,is originally designed to target epidermal growth factor receptor(EGFR)-activating mutations.Previous studies have shown that abivertinib has promising antitumor activity and a well-tolerated safety profile in patients with non-small-cell lung cancer.However,abivertinib also exhibited high inhibitory activity against Bruton’s tyrosine kinase and Janus kinase 3.Given that these kinases play some roles in the progression of megakaryopoiesis,we speculate that abivertinib can affect megakaryocyte(MK)differentiation and platelet biogenesis.We treated cord blood CD34+hematopoietic stem cells,Meg-01 cells,and C57BL/6 mice with abivertinib and observed megakaryopoiesis to determine the biological effect of abivertinib on MK differentiation and platelet biogenesis.Our in vitro results showed that abivertinib impaired the CFU-MK formation,proliferation of CD34+HSC-derived MK progenitor cells,and differentiation and functions of MKs and inhibited Meg-01-derived MK differentiation.These results suggested that megakaryopoiesis was inhibited by abivertinib.We also demonstrated in vivo that abivertinib decreased the number of MKs in bone marrow and platelet counts in mice,which suggested that thrombopoiesis was also inhibited.Thus,these preclinical data collectively suggested that abivertinib could inhibit MK differentiation and platelet biogenesis and might be an agent for thrombocythemia. | Jiansong Huang Xin Huang Yang Li Xia Li Jinghan Wang Fenglin Li Xiao Yan Huanping Wang Yungui Wang Xiangjie Lin Jifang Tu Daqiang He Wenle Ye Min Yang Jie Jin | 2022 | Frontiers of Medicine2022,16,3: | 0 |
