1Prevalence of Autism Spectrum Disorder in China:A Nationwide Multi-center Population-based Study Among Children Aged 6 to 12 Years显示文摘This study aimed to obtain the first national estimate of the prevalence of autism spectrum disorder(ASD) in Chinese children.We targeted the population of 6 to 12-year-old children for this prevalence study by multistage convenient cluster sampling.The Modified Chinese Autism Spectrum Rating Scale was used for the screening process.Of the target population of 142,086 children,88.5%(n=125,806) participated in the study.A total of 363 children were confirmed as having ASD.The observed ASD prevalence rate was 0.29%(95% CI:0.26%-0.32%) for the overall population.After adjustment for response rates,the estimated number of ASD cases was867 in the target population sample,thereby achieving an estimated prevalence of 0.70%(95% CI:0.64%-0.74%).The prevalence was significantly higher in boys than in girls(0.95%;95% CI:0.87%-1.02% versus 0.30%;95%CI:0.26%-0.34%;P <0.001).Of the 363 confirmed ASD cases,43.3% were newly diagnosed,and most of those(90.4%) were attending regular schools,and 68.8% of the children with ASD had at least one neuropsychiatric comorbidity.Our findings provide reliable data on the estimated ASD prevalence and comorbidities in Chinese children.Hao Zhou Xiu Xu Weili Yan Xiaobing Zou Lijie Wu Xuerong Luo Tingyu Li Yi Huang Hongyan Guan Xiang Chen Meng Mao Kun Xia Lan Zhang Erzhen Li Xiaoling Ge Lili Zhang Chunpei Li Xudong Zhang Yuanfeng Zhou Ding Ding Andy Shih Eric Fombonne Yi Zheng Jisheng Han Zhongsheng Sun Yong-hui Jiang Yi Wang LATENT-NHC Study Team 2020Neuroscience Bulletin2020,36,9:158
22018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54
3Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21
4Whole-genome sequencing of 508 patients identifies key molecular features associated with poor prognosis in esophageal squamous cell carcinoma显示文摘Esophageal squamous cell carcinoma(ESCC)is a poor-prognosis cancer type with limited understanding of its molecular etiology.Using 508 ESCC genomes,we identified five novel significantly mutated genes and uncovered mutational signature clusters associated with metastasis and patients’outcomes.Several functional assays implicated that NFE2L2 may act as a tumor suppressor in ESCC and that mutations in NFE2L2 probably impaired its tumor-suppressive function,or even conferred oncogenic activities.Additionally,we found that the NFE2L2 mutations were significantly associated with worse prognosis of ESCC.We also identified potential noncoding driver mutations including hotspot mutations in the promoter region of SLC35E2 that were correlated with worse survival.Approximately 5.9%and 15.2%of patients had high tumor mutation burden or actionable mutations,respectively,and may benefit from immunotherapy or targeted therapies.We found clinically relevant coding and noncoding genomic alterations and revealed three major subtypes that robustly predicted patients’outcomes.Collectively,we report the largest dataset of genomic profiling of ESCC useful for developing ESCC-specific biomarkers for diagnosis and treatment.Yongping Cui Hongyan Chen Ruibin Xi Heyang Cui Yahui Zhao Enwei Xu Ting Yan Xiaomei Lu Furong Huang Pengzhou Kong Yang Li Xiaolin Zhu Jiawei Wang Wenjie Zhu Jie Wang Yanchun Ma Yong Zhou Shiping Guo Ling Zhang Yiqian Liu Bin Wang Yanfeng Xi Ruifang Sun Xiao Yu Yuanfang Zhai Fang Wang Jian Yang Bin Yang Caixia Cheng Jing Liu Bin Song Hongyi Li Yi Wang Yingchun Zhang Xiaolong Cheng Qimin Zhan Yanhong Li Zhihua Liu-Show 2020Cell Research2020,30,10:19
5Effects of dietary supplementation of Artemisia argyi aqueous extract on antioxidant indexes of small intestine in broilers显示文摘The present study was conducted to investigate the effect of Artemisia argyi aqueous extract(AAE) on antioxidant indexes in the small intestine. A total of 192 Arbor Acre broiler chickens(one-day-old) were randomly divided into 4 treatments with 6 replicates of 8 chickens. These 4 diets were formulated by adding 0, 500,1,000 and 2,000 mg/kg AAE to the basal diet. The results showed as follows: 1) compared with the control, the total antioxidant capacity(T-AOC) in ileum for the 2,000 mg/kg treatment group was significantly increased at 21 days of age(P < 0.05); the T-AOC levels in jejunum and ileum were significantly increased in broilers supplemented with 500 mg/kg AAE at 42 days of age(P < 0.05), and the T-AOC levels in jejunum and ileum were significantly improved in 1,000 mg/kg treatment group(P < 0.01), 2) At 21 days of age, supplementation of 500 mg/kg AAE significantly increased the catalase(CAT) activity of small intestine, and the glutathione peroxidase(GSH-Px) activity of jejunum was improved(P < 0.01), meanwhile, the GSH-Px activity of duodenum and the total superoxide dismutase(T-SOD) activity of duodenum and jejunum were significantly higher than those of the control group(P < 0.05); supplementation of 1,000 mg/kg AAE significantly increased the CAT activity of duodenum and ileum and the GSH-Px activity of duodenum and jejunum(P < 0.05), and the ileum GSH-Px activity was significantly increased(P < 0.01); supplementation of 2,000 mg/kg AAE significantly increased the CAT activity of duodenum and ileum(P < 0.05). At 42 days of age, supplementation of 500 mg/kg AAE significantly increased the GSH-Px activity of ileum and the T-SOD activity of duodenum(P < 0.05),meanwhile, the T-SOD activity of jejunum was significantly increased(P < 0.01); supplementation of1,000 mg/kg AAE significantly increased the CAT activity of jejunum and the T-SOD activity of ileum(P < 0.01), and the GSH-Px activity of jejunum was significantly increased(P < 0.05); supplementation of2,000 mg/kg AAE significantly increased the T-SOD activity of ileum(P < 0.05), but significantly decreased the CAT activity of ileum and the GSH-Px activity of jejunum(P < 0.05). 3) The malondialdehyde(MDA) levels of 3 AAE supplementation groups were significantly decreased at 21 and 42 days of age(P < 0.05). The results suggested that dietary supplementation with AAE could improve the antioxidative capacity of small intestine in broilers.Fei Zhao Binlin Shi Dengsheng Sun Hongyan Chen Manman Tong Pengfei Zhang Xiaoyu Guo Sumei Yan 2016Animal Nutrition2016,,3:18

9The influence of tectonic evolution on the accumulation and enrichment of coalbed methane (CBM)显示文摘The current accumulation and enrichment of CBM reservoir is a result of the preservation and destruction of former CBM, after the superposing evolution of reversing-and-uplifting and the subsequent evolution within the coal-bearing basin. The critical moment of the CBM reservoir formation is the time when the burying depth of the overlying net thickness amounts to the least in geological history after the gas generation of coal beds. Except the coal-bearing basins of lower metamorphism, most basins suffered the evolution stage of reversion and uplift. The formation of the CBM reservoir is controlled by the beginning and lasting time, and the intensity of reversing and uplifting. The tectonic evolution after reversing and uplifting also affects the accumulation of CBM in coal-bearing basin. The CBM constantly dissipates in the area of chronically uplifting and de-nudating. The area developed overlying sedimentation is advantageous to the preservation of CBM, but also can lead to the reduction of CBM saturation.SONG Yan ZHAO Mengjun LIU Shaobo WANG Hongyan CHEN Zhenhong 2005Chinese Science Bulletin2005,50,S1:13
10Baicalin extracted from Huangqin(Radix Scutellariae Baicalensis) induces apoptosis in gastric cancer cells by regulating B cell lymphoma(Bcl-2)/Bcl-2-associated X protein and activating caspase-3 and caspase-9显示文摘OBJECTIVE:To evaluate the effects of baicalin in human gastric cancer cells, including apoptosis-inducing effects, and to investigate its underlying mechanisms of action.METHODS:Cell proliferation and apoptosis assays were performed to investigate the anti-proliferation effects of baicalin in human gastric cancer BGC-823 and MGC-803 cells.Real time-quantitative polymerase chain reaction and Western blotting analysis were performed to elucidate the molecular mechanisms underlying the anti-tumor properties of baicalin.RESULTS:In BGC-823 and MGC-803 gastric cancer cells treated with 80, 120, and 160 μmol/L baicalin for 48 h, a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay showed that baicalin significantly inhibited cell proliferation in a dose-dependent manner, while flow cytometric analysis demonstrated that baicalin could induce apoptosis, also in a dose-dependent manner.Moreover, baicalin up-regulated the expression of caspase-3, caspase-9, and B cell lymphoma(Bcl-2)-associated X protein and down-regulated the expression of Bcl-2 at both the m RNA and protein level.CONCLUSION:Baicalin has potential as a therapeutic agent for gastric cancer by inducing apoptosis in cancer cells.Wang Hongwei Li Hailong Chen Fengqin Luo Jun Gu Jing Wang Huping Wu Hongyan Xu Yan 2017Journal of Traditional Chinese Medicine2017,37,2:13
11Activation of northern margin of the North China Craton in Late Paleozoic:Evidence from U-Pb dating and Hf isotopes of detrital zircons from the Upper Carboniferous Taiyuan Formation in the Ningwu-Jingle basin显示文摘LA-MC-ICPMS U-Pb dating has been performed on detrital zircons from the Upper Carboniferous Tai-yuan Formation (N-8) in the Ningwu-Jingle Basin, west of the North China Craton (NCC). The ages of 72 detrital zircon grains are divided into three groups: 303―320 Ma (6 grains), 1631―2194 Ma (37 grains, peaked at 1850 Ma), 2318―2646 Ma (29 grains, peaked at 2500 Ma). Detrital zircons of Group 2 and Group 3 were likely derived from the basement of the NCC. Group 1 zircons exhibit 176Hf/177Hf ratios ranging from 0.281725 to 0.282239, with corresponding negative εHf(t) values of -12.4―-30.3 and old Hf model ages of 1.4―2.2 Ga. These characteristics show a strong resemblance to those of Carboniferous igneous zircons from the Inner Mongolia Paleo-uplift (IMPU) on the northern margin of the NCC, but differ significantly from those of the Xing-Meng Orogenic Belt, suggesting that the source of the Tai-yuan Formation partly came from the IMPU. All detrital zircons of Group 1 have relatively high Th/U ratios (> 0.67), indicating a magmatic origin. The mean age (304 ± 6 Ma) of the two youngest grains is close to the depositional age of the Taiyuan Formation, suggesting a strong tectonic uplift and magmatism in the IMPU during the Late Carboniferous. This paper provides important geological evidence for the activation of the northern margin of the NCC in the Late Paleozoic.LI HongYan XU YiGang HUANG XiaoLong HE Bin LUO ZhenYu YAN Bin 2009Chinese Science Bulletin2009,54,4:12

13Two-photon-excited near-infrared emissive carbon dotsas multifunctional agents for fluorescence imaging andphotothermal therapy显示文摘C dots (CDs) have shown great potential in bioimaging and phototherapy.However, it is challenging to manipulate their fluorescent properties andtherapeutic efficacy to satisfy the requirements for clinic applications. In thisstudy, we prepared S, Se-codoped CDs via a hydrothermal method anddemonstrated that the doping resulted in excitation wavelength-independentnear-infrared (NIR) emissions of the CDs, with peaks at 731 and 820 nm.Significantly, the CDs exhibited a photothermal conversion efficiency of -58.2%,which is the highest reported value for C nanostructures and is comparable tothat of Au nanostructures. Moreover, the CDs had a large two-photon absorptioncross section (-30,045 GM), which allowed NIR emissions and the photothermalconversion of the CDs through the two-photon excitation (TPE) mechanism. Invitro and in vivo tests suggested that CDs can function as new multi functionalphototheranostic agents for the TPE fluorescence imaging and photothermaltheraov of cancer cells.Minhuan Lan Shaojing Zhao Zhenyu Zhang Li Yan Liang Guo Guangle Niu Jinfeng Zhang Junfang Zhao Hongyan Zhang Pengfei Wang Guangyu Zhu Chun-Sing Lee Wenjun Zhang 2017Nano Research2017,10,9:9

16Emerging transporter-targeted nanoparticulate drug delivery systems显示文摘Transporter-targeted nanoparticulate drug delivery systems(nano-DDS) have emerged as promising nanoplatforms for efficient drug delivery. Recently, great progress in transporter-targeted strategies has been made, especially with the rapid developments in nanotherapeutics. In this review, we outline the recent advances in transporter-targeted nano-DDS. First, the emerging transporter-targeted nano-DDS developed to facilitate oral drug delivery are reviewed. These include improvements in the oral absorption of protein and peptide drugs, facilitating the intravenous-to-oral switch in cancer chemotherapy. Secondly, the recent advances in transporter-assisted brain-targeting nano-DDS are discussed,focusing on the specific transporter-based targeting strategies. Recent developments in transportermediated tumor-targeting drug delivery are also discussed. Finally, the possible transport mechanisms involved in transporter-mediated endocytosis are highlighted, with special attention to the latest findings of the interactions between membrane transporters and nano-DDS.Hongyan Su Yan Wang Shuo Liu Yue Wang Qian Liu Guangxuan Liu Qin Chen 2019Acta Pharmaceutica Sinica B2019,9,1:9
17Clinical applications of MARSALA for preimplantation genetic diagnosis of spinal muscular atrophy显示文摘Conventional PCR methods combined with linkage analysis based on short tandem repeats(STRs) or Karyomapping with single nucleotide polymorphism(SNP) arrays, have been applied to preimplantation genetic diagnosis(PGD) for spinal muscular atrophy(SMA), an autosome recessive disorder. However, it has limitations in SMA diagnosis by Karyomapping, and these methods are unable to distinguish wildtype embryos with carriers effectively. Mutated allele revealed by sequencing with aneuploidy and linkage analyses(MARSALA) is a new method allowing embryo selection by a one-step next-generation sequencing(NGS) procedure, which has been applied in PGD for both autosome dominant and X-linked diseases in our group previously. In this study, we carried out PGD based on MARSALA for two carrier families with SMA affected children. As a result, one of the couples has given birth to a healthy baby free of mutations in SMA-causing gene. It is the first time that MARSALA was applied to PGD for SMA, and we can distinguish the embryos with heterozygous deletion(carriers) from the wild-type(normal) ones accurately through this NGS-based method. In addition, direct mutation detection allows us to identify the affected embryos(homozygous deletion), which can be regarded as probands for linkage analysis, in case that the affected family member is absent. In the future, the NGS-based MARSALA method is expected to be used in PGD for all monogenetic disorders with known pathogenic gene mutation.Yixin Ren Xu Zhi Xiaohui Zhu Jin Huang Ying Lian Rong Li Hongyan Jin Yan Zhang Wenxin Zhang Yanli Nie Yuan Wei Zhaohui Liu Donghong Song Ping Liu Jie Qiao Liying Yan 2016Journal of Genetics and Genomics2016,43,9:9
18A novel mutation in the MITF may be digenic with GJB2 mutations in a large Chinese family of Waardenburg syndrome type Ⅱ显示文摘Waardenburg syndrome typeⅡ(WS2) is associated with syndromic deafness.A subset of WS2,WS2A,accounting for approximately 15%of patients,is attributed to mutations in the microphthalmia-associated transcription factor(MITF) gene.We examined the genetic basis of WS2 in a large Chinese family.All 9 exons of the MITF gene,the single coding exon(exon 2) of the most common hereditary deafness gene GJB2 and the mitochondrial DNA(mtDNA) 12S rRNA were sequenced.A novel heterozygous mutation c.[742_743delAAinsT;746_747delCA]in exon 8 of the MITF gene co-segregates with WS2 in the family.The MITF mutation results in a premature termination codon and a truncated MITF protein with only 247 of the 419 wild type amino acids.The deaf proband had this MITF gene heterozygous mutation as well as a c.[109G>A]+ [235delC]compound heterozygous pathogenic mutation in the GJB2 gene.No pathogenic mutation was found in mtDNA 12S rRNA in this family.Thus,a novel compound heterozygous mutation,c.[742_743delAAinsT;746_747delCA]in MITF exon 8 was the key genetic reason for WS2 in this family,and a digenic effect of MITF and GJB2 genes may contribute to deafness of the proband.Xukun Yan Tianyu Zhang Zhengmin Wang Yi Jiang Yan Chen Hongyan Wang Duan Ma Lei Wang Huawei Li 2011Journal of Genetics and Genomics2011,38,12:8
19Phase transformation and microstructure control of Ti_(2)AlNb-based alloys: A review显示文摘In recent years,the Ti_(2) AlNb-based alloys are selected as potential alloys for elevated tempe rature applications to replace conventional Ni-based superalloys owing to their good creep resistance and oxidation resistance which are related to the O precipitates.In this paper,the precipitation mecha nisms of O phase,phase transformation and microstructure control of Ti_(2) AlNb-based alloys are reviewed.Ti_(2) AlNb-based alloys generally consist of B2/β,α_(2),and O phase with different morphologies which are derived from the various heat treatment processes,including equiaxed α_(2)/O particles,bimodal microstructure,and Widmannstatten B2/β+O structures etc.As a newly developed strengthening phase,O precipitates can be precipitated from the B2/β matrix or α_(2) phase directly as well as generated by means of peritectoid reaction of α_(2) phase and bcc matrix.Microstructural control of the Ti_(2) AlNb-based alloys can be implemented by refining the original B2/β grain size and regulating the O precipitates.Multidirectional isothermal forging(MIF) and powder metallurgy technique are two effective methods to refine the original B2/βgrains and the morphology and size of O precipitates can be regulated by adding alloying components and pre-deformation process.Moreover,the phase diagram as well as coarsening behavior of Ti_(2) AlNbbased alloys in ageing process is also reviewed.For the further application of these alloys,more emphasis should be paid on the deep interpolation of microstructure-property relationship and the adoption of advanced manufacturing technology.Hongyu Zhang Na Yan Hongyan Liang Yongchang Liu 2021Journal of Materials Science & Technology2021,,21:7
20Chimeric antigen receptor T cells in solid tumors: a war against the tumor microenvironment显示文摘Chimeric antigen receptor(CAR) T cell is a novel approach, which utilizes anti-tumor immunity for cancer treatment. As compared to the traditional cell-mediated immunity, CAR-T possesses the improved specificity of tumor antigens and independent cytotoxicity from major histocompatibility complex molecules through a monoclonal antibody in addition to the Tcell receptor. CAR-T cell has proven its effectiveness, primarily in hematological malignancies, specifically where the CD19 CAR-T cells were used to treat B-cell acute lymphoblastic leukemia and B-cell lymphomas. Nevertheless, there is little progress in the treatment of solid tumors despite the fact that many CAR agents have been created to target tumor antigens such as CEA,EGFR/EGFRvIII, GD2, HER2, MSLN, MUC1, and other antigens. The main obstruction against the progress of research in solid tumors is the tumor microenvironment, in which several elements, such as poor locating ability, immunosuppressive cells,cytokines, chemokines, immunosuppressive checkpoints, inhibitory metabolic factors, tumor antigen loss, and antigen heterogeneity, could affect the potency of CAR-T cells. To overcome these hurdles, researchers have reconstructed the CAR-T cells in various ways. The purpose of this review is to summarize the current research in this field, analyze the mechanisms of the major barriers mentioned above, outline the main solutions, and discuss the outlook of this novel immunotherapeutic modality.Zijun Zhao Xiaoyun Xiao Phei Er Saw Wei Wu Hongyan Huang Jiewen Chen Yan Nie 2020Science China(Life Sciences)2020,63,2:7
