| 1 | Famitinib in combination with concurrent chemoradiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma: a phase 1, open-label, dose-escalation Study显示文摘Background:Famitinib is a tyrosine kinase inhibitor against multiple targets,including vascular endothelial growth factor receptor 2/3,platelet-derived growth factor receptor,and stem cell factor receptor(c-kit).Previous studies have demonstrated anti-tumour activities of famitinib against a wide variety of advanced-stage solid cancers.We aimed to determine the safety and efficacy of famitinib with concurrent chemoradiotherapy(CCRT)in patients with locoregionally advanced nasopharyngeal carcinoma(NPC).We also evaluated the feasibility of contrast-enhanced ultrasound(D-CEUS)as a predictor of early tumour response to famitinib and to correlate functional parameters with clinical efficacy.Methods:The trial was conducted in subjects with stage III or IVa-b NPC using a 3+3 design of escalating fami-tinib doses.Briefly,subjects received 2 weeks of famitinib monotherapy followed by 7 weeks of famitinib plus CCRT.D-CEUS of the neck lymph nodes was performed at day 0,8 and 15 after famitinib was administered before starting concurrent chemoradiotherapy.End points included safety,tolerability and anti-tumour activity.Results:Twenty patients were enrolled(six each for 12.5,16.5 and 20 mg and two for 25 mg).Two patients in the 25 mg cohort developed dose-limiting toxicities,including grade 4 thrombocytopenia and grade 3 hypertension.The most common grade 3/4 adverse events were leukopenia,neutropenia and radiation mucositis.D-CEUS tests showed that more than 60%of patients achieved a perfusion parameter response after 2 weeks taking famitinib alone,and the parameter response was associated with disease improvement.In the famitinib monotherapy stage,three patients(15%)showed partial responses.The complete response rate was 65%at the completion of treatment and 95%3 months after the treatment ended.After a median follow-up of 44 months,the 3-year progression-free survival(PFS)and distant metastasis-free survival were 70%and 75%,respectively.Subjects with a decrease of perfusion parameter response,such as peak intensity decreased at least 30%after 1 week of famitinib treatment,had higher 3-year PFS(90.9%vs.44.4%,95%CI 73.7%-100%vs.11.9%-76.9%,P<0.001)than those with an increase or a reduction of less than 30%.Conclusions:The recommended famitinib dose for phase II trial is 20 mg with CCRT for patients with local advanced NPC.D-CEUS is a reliable and early measure of efficacy for famitinib therapies.Further investigation is required to confirm the effects of famitinib plus chemoradiotherapy. | Qiuyan Chen Linquan Tang Na Liu Feng Han Ling Guo Shanshan Guo Jianwei Wang Huai Liu Yanfang Ye Lu Zhang Liting Liu Pan Wang Yingqin Li Qingmei He Xiaoqun Yang Qingnan Tang Yang Li YuJing Liang XueSong Sun Chuanmiao Xie Yunxian Mo Ying Guo Rui Sun Haoyuan Mo Kajia Cao Xiang Guo Musheng Zeng Haiqiang Mai Jun Ma | 2018 | Cancer Communications2018，38，1： | 6 |
| 2 | The landscape of aging显示文摘Aging is characterized by a progressive deterioration of physiological integrity,leading to impaired functional ability and ultimately increased susceptibility to death.It is a major risk factor for chronic human diseases,including cardiovascular disease,diabetes,neurological degeneration,and cancer.Therefore,the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences.In recent years,there has been unprecedented progress in aging research,particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes.In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases,we review the descriptive,conceptual,and interventive aspects of the landscape of aging composed of a number of layers at the cellular,tissue,organ,organ system,and organismal levels. | Yusheng Cai Wei Song Jiaming Li Ying Jing Chuqian Liang Liyuan Zhang Xia Zhang Wenhui Zhang Beibei Liu Yongpan An Jingyi Li Baixue Tang Siyu Pei Xueying Wu Yuxuan Liu Cheng-Le Zhuang Yilin Ying Xuefeng Dou Yu Chen Fu-Hui Xiao Dingfeng Li Ruici Yang Ya Zhao Yang Wang Lihui Wang Yujing Li Shuai Ma Si Wang Xiaoyuan Song Jie Ren Liang Zhang Jun Wang Weiqi Zhang Zhengwei Xie Jing Qu Jianwei Wang Yichuan Xiao Ye Tian Gelin Wang Ping Hu Jing Ye Yu Sun Zhiyong Mao Qing-Peng Kong Qiang Liu Weiguo Zou Xiao-Li Tian Zhi-Xiong Xiao Yong Liu Jun-Ping Liu Moshi Song Jing-Dong J.Han Guang-Hui Liu | 2022 | Science China(Life Sciences)2022，65，12： | 4 |
| 3 | Protecting endemic seed plants on the Tibetan Plateau under future climate change: migration matters显示文摘Aims Climate change in the near future may become a major threat to high-altitude endemics by greatly altering their distribution.Our aims are to(i)assess the potential impacts of future climate change on the diversity and distribution of seed plants endemic to the Tibetan Plateau and(ii)evaluate the conservation effectiveness of the current National Nature Reserves(NNRs)in protecting the endemic plants in the face of climate change.Methods We projected range shifts of 993 endemic species to the years 2050 and 2070 under two representative concentration pathway scenarios using an ensemble species distribution modeling framework and evaluated range loss,species-richness change and coverage of the current conservation network considering two dispersal scenarios.Important Findings In a full-dispersal scenario,72–81%of the species would expand their distribution by 2070,but 6–20%of the species would experience>30%range loss.Most species would shift to the west.The projected species net richness would increase across the region on average.In a no-dispersal scenario,15–59%of the species would lose>30%of their current habitat by 2070.Severe species loss may occur in the southeastern and the eastern peripheral plateau.Seventeen percent of species ranges are covered by the NNRs on average and may increase in the future if species disperse freely.We found a significant difference of species redistribution patterns between different dispersal scenarios and highlighted the importance of migration in this region. | Yujing Yan Zhiyao Tang | 2019 | Journal of Plant Ecology2019，12，6： | 4 |
| 4 | Efficient silencing of the multicopy DUX4 gene by ABE-mediated start codon mutation in human embryos显示文摘The Dux gene plays an important role in mouse embryo development(De Iaco et al.,2017;Hendrickson et al.,2017;Whiddon et al.,2017).It participates in the maternal-to-zygotic transition(MTZ),which mainly includes maternal transcript degradation and zygotic genome activation(ZGA)and is the key process for embryonic development.Approximately 11-100 copies of the DUX4 gene form a tandem cluster in the human genome(Snider et al.,2009,2010). | Yubing Liu Xinmei Lu Min Ye Ling Wang Rongxin Tang Zhiyong Yang Bongkoch Turathum Chenchen Liu Yujing Xue Menghua Wu Yannan Yang Ermeng Gao Di Zhang Feng Yang Keh-Kooi Kee Xingxu Huang Guanglei Li Ri-Cheng Chian | 2022 | Journal of Genetics and Genomics2022，49，10： | 1 |
| 5 | GSH-induced chemotaxis nanomotors for cancer treatment by ferroptosis strategy显示文摘Overexpression of glutathione(GSH) in tumor cells greatly inhibits the therapy effect of traditional ferroptosis inducers;thus,control of the GSH level is an important way to improve the efficacy of ferroptosis.Herein,a kind of nanomotor based on metal organic framework material NH_(2)-MIL-101 is constructed,in which polyethylene glycol(PEG) and glutathione hydrolase γ-glutamyltransferase(GGT) are asymmetrically modified to obtain mPEG@MIL-101@GGT nanomotors(PMG NMs).The nanomotor proposed in this article can be induced by overexpressing GSH in tumors to form chemotactic effects through the specific affinity between enzymes and substrates.Results indicate that the tail structure provided by PEG and the affinity between GGT and GSH can enable the stable chemotaxis behavior of nanomotors in a complex environment,thus enriching and penetrating deeply at the tumor site.In addition,after loading the ferroptosis inducer Erastin,the system shows a highly effective induction effect of tumor ferroptosis.Erastin in the system can effectively inhibit the synthesis of GSH,and PMG NMS can react with GSH through Fe^(3+)and GGT to promote GSH depletion.The produced Fe^(2+)can generate excessive reactive oxygen species through Fenton reaction,which further promotes the death of tumor cells.Meantime,the chemotaxis behavior of the nanomotors based on the endogenous biochemical reaction of GGT-catalyzed GSH hydrolysis can endow nanomotors with the enhanced delivery and penetration ability in tumors,thus collaboratively enhancing the ferroptosis effect.This strategy designed according to the physiological characteristics of tumors has good biosafety and treatment effect,providing new perspectives for micro/nanomotor and tumor treatment. | Zhiyong Liu Ting Li Nan Li Yujing Wang Lin Chen Xueting Tang Mimi Wan Chun Mao | 2022 | Science China Chemistry2022，65，5： | 1 |
| 6 | Establishment of a prognostic scoring model for regional recurrent nasopharyngeal carcinoma after neck dissection显示文摘Objective:The main aim of this study was to establish a scoring model to predict risk of progression and survival in patients with regionally recurrent nasopharyngeal carcinoma(NPC).Methods:Three hundred and forty-eight patients subjected to neck dissection from 2003 to 2017 were included for study.Clinicopathologic information for each patient was analyzed.Independent prognostic factors were selected using the Cox proportional hazards model and incorporated into the scoring model.Concordance index(C-index)and calibration curves were used to verify discrimination and calibration,respectively and the results validated using bootstrap resampling.Results:Microscopic positive lymph node>2[hazard ratio(HR),2.19;95%confidence interval(CI),1.30–3.68;P=0.003],extranodal extension(HR,2.75;95%CI,1.69–4.47;P<0.001),and lower neck involvement(HR,1.78;95%CI,1.04–3.04;P=0.034)were identified from multivariate analysis as independent factors for overall survival(OS).A qualitative 4-point scale was generated to stratify patients into 4 risk groups for predicting OS and progression-free survival(PFS).The novel scoring model demonstrated enhanced discrimination(C-index=0.69;95%CI,0.62–0.76)relative to the original recurrent tumor-node-metastasis(rTNM)staging system(C-index=0.56;95%CI,0.50–0.62),and was internally validated with a bootstrap-adjusted C-index of 0.70.The calibration curve showed good agreement between predicted probabilities and actual observations.Conclusions:The scoring system established in this study based on a large regionally recurrent NPC cohort fills a gap regarding assessment of risk and prediction of survival outcomes after neck dissection in this population and could be further applied to identify high-risk patients who may benefit from more aggressive intervention. | Xiaoyun Li Chao Lin Jinjie Yan Qiuyan Chen Xuesong Sun Sailan Liu Shanshan Guo Liting Liu Haojun Xie Qingnan Tang Yujing Liang Ling Guo Hao Li Xuekui Liu Xiang Guo Linquan Tang Haiqiang Mai | 2020 | Cancer Biology & Medicine2020，17，1： | 0 |
| 7 | Towards Human‑Vehicle Interaction: Driving Risk Analysis Under Different Driver Vigilance States and Driving Risk Detection Method显示文摘The driver's behavior plays a crucial role in transportation safety.It is widely acknowledged that driver vigilance is a major contributor to traffic accidents.However,the quantitative impact of driver vigilance on driving risk has yet to be fully explored.This study aims to investigate the relationship between driver vigilance and driving risk,using data recorded from 28 drivers who maintain a speed of 80 km/h on a monotonous highway for 2 hours.The k-means and linear fitting methods are used to analyze the driving risk distribution under different driver vigilance states.Additionally,this study proposes a research framework for analyzing driving risk and develops three classification models(KNN,SVM,and DNN)to recognize the driving risk status.The results show that the frequency of low-risk incidents is negatively correlated with the driver's vigilance level,whereas the frequency of moderate-risk and high-risk incidents is positively correlated with the driver's vigilance level.The DNN model performs the best,achieving an accuracy of 0.972,recall of 0.972,precision of 0.973,and f1-score of 0.972,compared to KNN and SVM.This research could serve as a valuable reference for the design of warning systems and intelligent vehicles. | Yingzhang Wu Jie Zhang Wenbo Li Yujing Liu Chengmou Li Bangbei Tang Gang Guo | 2023 | Automotive Innovation2023，6，1： | 0 |
| 8 | CATase-immobilized hydrogel platform molded by photo-enzyme coupling polymerization for effectively preventing postoperative abdominal adhesion显示文摘Redox homeostasis,which is regulated by enzymes acting as regulatory valves,is crucial for maintaining the proper functioning of biomolecules and a stable microenvironment for physiological processes by modulating the homeostasis of reactive oxygen species(ROS).Antioxidant enzymes in biocatalysis are used in the prevention or treatment of oxidative stress-related disease by counteracting the harmful effects of ROS.However,designing a system that can efficiently immobilize antioxidant enzymes with high catalytic activity and stability is still challenging.Bioinspired by photo-biocatalysis,a novel and effective catalase(CATase)-immobilized hydrogel platform has been developed by the proposed photo-enzymatic coupled radical polymerization strategy of the visible light coupling with the porphyrin-centered CATase.The higher catalytic stability and activity can therefore be achieved due to the preferential polymerization of CATase-immobilized hydrogel platform with a favorable three-dimensional network of enhanced coupling efficacy between light and enzymes.The mechanisms of free radical-initiated polymerization as well as the antioxidant cycle in the photo-CATase coupling system have been explored.Intriguingly,the CATase-immobilized hydrogel platform affords an unprecedented antioxidant ability to scavenge ROS and provide an effective cellular protection mechanism against external oxidative stress.Additionally,the CATase-immobilized hydrogel platform can effectively prevent peritoneal adhesion by reducing the expression of inflammatory cytokines.Therefore,the novel CATase-immobilized hydrogel platform is a potential candidate for physical barriers that effectively prevent postoperative adhesion formation,offering a new anti-adhesion strategy for clinical applications. | Min Hu Mingyue Shi Xia Wang Yujing Tang Dingze Zhou Kai Pan Qigang Wang | 2023 | Science China Chemistry2023，66，9： | 0 |
| 9 | Prognostic significance of a combined and controlled nutritional status score and EBV-DNA in patients with advanced nasopharyngeal carcinoma:a long-term follow-up study显示文摘Objective:Several studies have reported that the controlling nutritional status(CONUT)score is a prognostic predictor for survival among patients with different types of cancer.We assessed the prognostic value of changes in the CONUT score during treatment and theΔCONUT-EBV DNA score in patients with advanced nasopharyngeal carcinoma(NPC).Methods:We retrospectively analyzed 433 patients with advanced NPC having no evidence of metastasis from January 2007 to June 2011;the patients underwent radical concurrent chemoradiotherapy(CCRT)at Sun Yat-sen University Cancer Center and were grouped based on theirΔCONUT andΔCONUT-EBV DNA scores.Kaplan-Meier curves were used to compare the patient outcomes according to the cut-offΔCONUT score and theΔCONUT-EBV DNA scoring system.Results:Among all patients,overall survival(OS)was independently predicted by a highΔCONUT score(P=0.031)and high EBV DNA(P<0.001).TheΔCONUT-EBV DNA score[OS area under the curve(AUC)=0.621;progression free survival(PFS)-AUC=0.612;distant metastasis-free survival(DMFS)-AUC=0.622]was more predictive of OS,PFS,and DMFS in patients with advanced NPC than theΔCONUT score(OS-AUC=0.547;PFS-AUC=0.533;DMFS-AUC=0.522)and pretreatment plasma EBV DNA levels alone(OS-AUC=0.600;PFS-AUC=0.591,DMFS-AUC=0.610).TheΔCONUT-EBV DNA score was significantly correlated with OS,PFS,and DMFS in patients with advanced NPC treated with CCRT.Conclusions:TheΔCONUT-EBV DNA score may be useful in clinical practice as a convenient biomarker for predicting the outcomes in patients with advanced NPC treated with CCRT. | Hui Lu Shanshan Guo Liting Liu Qiuyan Chen Yujing Liang Sailan Liu Xuesong Sun QingnanTang Xiaoyun Li Ling Guo Haoyuan Mo Linquan Tang Haiqiang Mai | 2022 | Cancer Biology & Medicine2022，19，4： | 0 |
| 10 | Co-delivery of nigericin and decitabine using hexahistidine-metal nanocarriers for pyroptosis-induced immunotherapeutics显示文摘Pyroptosis provides a new window for relieving the tumor immunosuppressive microenvironment(TIM)and promoting systemic immune responses for tumor treatments.However,gasdermin D(GSDMD),a key protein in the pyroptosis process mediated by caspase-1,is low expressed in the majority of tumor cells and small-molecule inhibitors of DNA methylation suffer from nonspecific or single-function defects.To address these issues,hexahistidine(His6)-metal assembly(HmA)was employed as the drug delivery vector to load nigericin(Nig)and decitabine(DAC)affording a dual-drug delivery system(Nig^(+)DAC)@HmA.The(Nig^(+)DAC)@HmA nanoparticles are efficiently internalized by cells through endocytosis,easily escape from the lysosome,and are highly distributed in the tumor sites.DAC up-regulates the expression of GSDMD which is then cleaved by the nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)inflammasome and caspase-1 protein activated by Nig.Effective cancer cell pyroptosis is thus achieved and induces a significant systemic antitumor immunity for impressive tumor suppression with negligible side effects in vivo.Our results suggest that such an easy-to-manipulate self-assembled nano-system(Nig^(+)DAC)@HmA provides a new anticancer path by enhancing pyroptosis through reinforced inflammation. | Qiang Niu Yu Liu Yujing Zheng Ziwei Tang Yuna Qian Ruogu Qi Jianliang Shen Ping Zhao | 2022 | Acta Pharmaceutica Sinica B2022，12，12： | 0 |
| 11 | A biomimetic piezoelectric scaffold with sustained Mg^(2+)release promotes neurogenic and angiogenic differentiation for enhanced bone regeneration显示文摘Natural bone is a composite tissue made of organic and inorganic components,showing piezoelectricity.Whitlockite(WH),which is a natural magnesium-containing calcium phosphate,has attracted great attention in bone formation recently due to its unique piezoelectric property after sintering treatment and sustained release of magnesium ion(Mg^(2+)).Herein,a composite scaffold(denoted as PWH scaffold)composed of piezoelectric WH(PWH)and poly(ε-caprolactone)(PCL)was 3D printed to meet the physiological demands for the regeneration of neuro-vascularized bone tissue,namely,providing endogenous electric field at the defect site.The sustained release of Mg^(2+)from the PWH scaffold,displaying multiple biological activities,and thus exhibits a strong synergistic effect with the piezoelectricity on inhibiting osteoclast activation,promoting the neurogenic,angiogenic,and osteogenic differentiation of bone marrow mesenchymal stromal cells(BMSCs)in vitro.In a rat calvarial defect model,this PWH scaffold is remarkably conducive to efficient neo-bone formation with rich neurogenic and angiogenic expressions.Overall,this study presents the first example of biomimetic piezoelectric scaffold with sustained Mg^(2+)release for promoting the regeneration of neuro-vascularized bone tissue in vivo,which offers new insights for regenerative medicine. | Liangyu Wang Yanyun Pang Yujing Tang Xinyu Wang Daixing Zhang Xu Zhang Yingjie Yu Xiaoping Yang Qing Cai | 2023 | Bioactive Materials2023，，7： | 0 |
| 12 | 肢体骨肉瘤合并病理性骨折44例患者的临床特征及预后相关因素分析(英文)显示文摘Objective: The aim of this study was to identify the clinical features and prognostic factors associated with extremity osteosarcoma with pathologic fracture. Methods: The clinical records of 271 patients with extremity osteosarcomas were retrospectively reviewed. The data obtained covered the period from October 2003 to May 2012, and included sex, age, tumor site etc. The mean follow-up time was 25.2 months(ranged from 1 to 117). Chi-square method and Kaplan-Meier method were used to compare clinical differences and overall survival between patients with or without pathologic fracture, respectively. The univariate analysis was used to determine the prognostic factors related with survival rate by log-rank test. The multivariate analysis of prognosis was performed by COX proportional hazards regression model. Results: The proportions of patients having a tumor's diameter of 10 cm or more(P = 0.038), locating upper limbs(P = 0.004) and receiving amputation surgery(P = 0.02) were significantly higher with pathological fracture group than without pathological fracture group. The local recurrence rate(P = 0.000) was also significantly higher in the pathological fracture group. The median survival time of patients with or without pathological fracture was 16(95% confidence interval: 14.6–17.4) months and 22(95% confidence interval: 19.8–24.1) months(P = 0.002). The Log-rank univariate analysis indicated that the tumor size, Enneking's surgical staging, Karnofsky performance status(KPS) score, cycles of adjuvant chemotherapy, local recurrence and metastasis were significantly related to overall survival. Multivariate Cox regression analysis revealed KPS score, cycles of adjuvant chemotherapy and metastasis were independent prognostic factors(P < 0.05). Conclusion: Compared with the patients without pathological fracture, a higher proportion of patients receiving amputation surgery or having larger tumor size, humeral osteosarcoma or local recurrence was observed in patients with pathological fracture, and the prognosis of these patients was poor. The independent prognostic factors of extremity osteosarcoma with pathologic fracture were the KPS score, cycles of adjuvant chemotherapy and metastasis. | Cong Tian Yujing Hang Lina Tang Feng Lin Daliu Min Yang Yao | 2014 | The Chinese-German Journal of Clinical Oncology2014，13，1： | 0 |
| 13 | Electrochemically mediated decarboxylative acylation of N-nitrosoanilines with α-oxocarboxylic acids显示文摘An efficient palladium-catalyzed electrooxidation C–H acylation reaction of N-nitrosoanilines with α-oxocarboxylic acids was developed. The anodic oxidation of the Pd(Ⅱ) intermediate was found to be the key to complete the reaction. In this case, the N-nitroso group was observed to be an effective directing group for C–H activation reaction. Moreover, the synthetic transformation of derivatives of natural products(L-menthol, dehydroepiandrosterone, and pregnenolone) was successfully realized. Finally, flow electrochemical synthesis of some substrates was achieved. | Xinyu Wang Shihong Wu Yujing Zhong Yingchun Wang Yingming Pan Haitao Tang | 2023 | Chinese Chemical Letters2023，34，2： | 0 |
