| 1 | Individualized prediction of perineural invasion in colorectal cancer: development and validation of a radiomics prediction model显示文摘Objective: To develop and validate a radiomics prediction model for individualized prediction of perineural invasion(PNI) in colorectal cancer(CRC).Methods: After computed tomography(CT) radiomics features extraction, a radiomics signature was constructed in derivation cohort(346 CRC patients). A prediction model was developed to integrate the radiomics signature and clinical candidate predictors [age, sex, tumor location, and carcinoembryonic antigen(CEA) level]. Apparent prediction performance was assessed. After internal validation, independent temporal validation(separate from the cohort used to build the model) was then conducted in 217 CRC patients. The final model was converted to an easy-to-use nomogram.Results: The developed radiomics nomogram that integrated the radiomics signature and CEA level showed good calibration and discrimination performance [Harrell's concordance index(c-index): 0.817; 95% confidence interval(95% CI): 0.811–0.823]. Application of the nomogram in validation cohort gave a comparable calibration and discrimination(c-index: 0.803; 95% CI: 0.794–0.812).Conclusions: Integrating the radiomics signature and CEA level into a radiomics prediction model enables easy and effective risk assessment of PNI in CRC. This stratification of patients according to their PNI status may provide a basis for individualized auxiliary treatment. | Yanqi Huang Lan He Di Dong Caiyun Yang Cuishan Liang Xin Chen Zelan Ma Xiaomei Huang Su Yao Changhong Liang Jie Tian Zaiyi Liu | 2018 | Chinese Journal of Cancer Research2018,30,1: | 23 |
| 2 | Effect of wheat bran insoluble dietary fiber with different particle size on the texture properties, protein secondary structure, and microstructure of noodles显示文摘This study was conducted to explore how the insoluble dietary fiber(IDF)of wheat bran with different particle size affects the texture properties,water distribution,protein secondary structure and microstructure of noodles.The results suggested that IDF addition increased the cooking loss and decreased the sensory evaluation because of the damage on dough structure,while as the IDF particle size decreased,the sensory score increased from 78.8 to 82.3 and cooking loss decreased from 8.65%to 7.65%,which could be attributed to that small particle-sized IDF limited the damage on protein network structure,decreased the T22 and t-structure,and increased the β1-structure.Moreover,IDF particle size had a significant correlation with protein secondary structures,texture properties and evaluation score of noodles.In conclusion,adding appropriate particle sizewould be an effectiveway of enhancing the nutritional and textural properties of noodles. | Jian Zhang Mengqin Li Chaoran Li Yanqi Liu | 2019 | Grain & Oil Science and Technology2019,2,4: | 20 |
| 3 | A 3rd Order WENO GLM-MHD Scheme for Magnetic Reconnection显示文摘A new numerical scheme of 3rd order Weighted Essentially Non-Oscillatory (WENO) type for 2.5D mixed GLM-MHD in Cartesian coordinates is proposed. The MHD equations are modified by combining the arguments as by Dellar and Dedner et al to couple the divergence constraint with the evolution equations using a Generalized Lagrange Multiplier (GLM). Moreover, the magnetohydrodynamic part of the GLM-MHD system is still in conservation form. Meanwhile, this method is very easy to add to an existing code since the underlying MHD solver does not have to be modified. To show the validation and capacity of its application to MHD problem modelling, interaction between a magnetosonic shock and a denser cloud and magnetic reconnection problems are used to verify this new MHD code. The numerical tests for 2D Orszag and Tang's MHD vortex, interaction between a magnetosonic shock and a denser cloud and magnetic reconnection problems show that the third order WENO MHD solvers are robust and yield reliable results by the new mixed GLM or the mixed EGLM correction here even if it can not be shown that how the divergence errors are transported as well as damped as done for one dimensional ideal MHD by Dedner et al. | FENG Xueshang ZHOU Yufen HU Yanqi | 2006 | 空间科学学报2006,26,1: | 9 |
| 4 | Sintilimab versus docetaxel as second-line treatment in advanced or metastatic squamous non-small-cell lung cancer:an open-label,randomized controlled phase 3 trial(ORIENT-3)显示文摘Background:Treatment options for Chinese patients with locally advanced or metastatic squamous-cell non-small-cell lung cancer(sqNSCLC)after failure of first-line chemotherapy are limited.This study(ORIENT-3)aimed to evaluate the efficacy and safety of sintilimab versus docetaxel as second-line treatment in patients with locally advanced or metastatic sqNSCLC.Methods:ORIENT-3 was an open-label,multicenter,randomized controlled phase 3 trial that recruited patients with stage IIIB/IIIC/IV sqNSCLC after failure with first-line platinum-based chemotherapy.Patients were randomized in a 1:1 ratio to receive either 200 mg of sintilimab or 75 mg/m^(2) of docetaxel intravenously every 3 weeks,stratified by the Eastern Cooperative Oncology Group performance status.The primary endpoint was overall survival(OS)in the full analysis set(FAS).Secondary endpoints included progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),duration of response(DoR)and safety.Results:Between August 25,2017,and November 7,2018,290 patients were randomized.For FAS,10 patients fromthe docetaxel armwere excluded.Themedian OS was 11.79(n=145;95%confidence interval[CI],10.28-15.57)months with sintilimab versus 8.25(n=135;95%CI,6.47-9.82)months with docetaxel(hazard ratio[HR]:0.74;95%CI,0.56-0.96;P=0.025).Sintilimab treatment significantly prolonged PFS(median 4.30 vs.2.79 months;HR:0.52;95%CI,0.39-0.68;P<0.001)and showed higher ORR(25.50%vs.2.20%,P<0.001)and DCR(65.50%vs.37.80%,P<0.001)than the docetaxel arm.The median DoRwas 12.45(95%CI,4.86-25.33)months in the sintilimab arm and 4.14(95%CI,1.41-7.23)months in the docetaxel arm(P=0.045).Treatment-related adverse events of grade≥3were reported in 26(18.1%)patients in the sintilimab arm and 47(36.2%)patients in the docetaxel arm.Exploratory biomarker analysis showed potential predictive values of expression levels of two transcription factors,including OVOL2(HR:0.35;P<0.001)and CTCF(HR:3.50;P<0.001),for sintilimab treatment.Conclusions:Compared with docetaxel,sintilimab significantly improved the OS,PFS,and ORR of Chinese patients with previously treated locally advanced or metastatic sqNSCLC. | Yuankai Shi Lin Wu Xinmin Yu Puyuan Xing Yan Wang Jianying Zhou Airong Wang Jianhua Shi Yi Hu Ziping Wang Guangyu An Yong Fang Sanyuan Sun Caicun Zhou Changli Wang Feng Ye Xingya Li Junye Wang Mengzhao Wang Yunpeng Liu Yanqiu Zhao Ying Yuan Jifeng Feng Zhendong Chen Jindong Shi Tao Sun Gang Wu Yongqian Shu Qisen Guo Yi Zhang Yong Song Shucai Zhang Yuan Chen Wei Li Hongrui Niu Wenwei Hu Lijun Wang Jianan Huang Yang Zhang Ying Cheng Zhengdong Wu Bo Peng Jiya Sun Christoph Mancao Yanqi Wang Luyao Sun | 2022 | Cancer Communications2022,42,12: | 8 |
| 5 | Radiomics-based predictive risk score: A scoring system for preoperatively predicting risk of lymph node metastasis in patients with resectable non-small cell lung cancer显示文摘Objective: To develop and validate a radiomics-based predictive risk score(RPRS) for preoperative prediction of lymph node(LN) metastasis in patients with resectable non-small cell lung cancer(NSCLC).Methods: We retrospectively analyzed 717 who underwent surgical resection for primary NSCLC with systematic mediastinal lymphadenectomy from October 2007 to July 2016. By using the method of radiomics analysis, 591 computed tomography(CT)-based radiomics features were extracted, and the radiomics-based classifier was constructed. Then, using multivariable logistic regression analysis, a weighted score RPRS was derived to identify LN metastasis. Apparent prediction performance of RPRS was assessed with its calibration,discrimination, and clinical usefulness.Results: The radiomics-based classifier was constructed, which consisted of 13 selected radiomics features.Multivariate models demonstrated that radiomics-based classifier, age group, tumor diameter, tumor location, and CT-based LN status were independent predictors. When we assigned the corresponding score to each variable,patients with RPRSs of 0-3, 4-5, 6, 7-8, and 9 had distinctly very low(0%-20%), low(21%-40%), intermediate(41%-60%), high(61%-80%), and very high(81%-100%) risks of LN involvement, respectively. The developed RPRS showed good discrimination and satisfactory calibration (C-index: 0.785, 95% confidence interval(95% CI):0.780-0.790)Additionally, RPRS outperformed the clinicopathologic-based characteristics model with net reclassification index(NRI) of 0.711(95% CI: 0.555-0.867).Conclusions: The novel clinical scoring system developed as RPRS can serve as an easy-to-use tool to facilitate the preoperatively individualized prediction of LN metastasis in patients with resectable NSCLC. This stratification of patients according to their LN status may provide a basis for individualized treatment. | Lan He Yanqi Huang Lixu Yan Junhui Zheng Changhong Liang Zaiyi Liu | 2019 | Chinese Journal of Cancer Research2019,31,4: | 7 |
| 6 | Lingguizhugan Decoction, a Chinese herbal formula, improves insulin resistance in overweight/obese subjects with non-alcoholic fatty liver disease: a translational approach显示文摘Lingguizhugan Decoction(LGZG)has been investigated in basic studies,with satisfactory effects on insulin resistance in non-alcoholic fatty liver disease(NAFLD).This translational approach aimed to explore the effect and underlying mechanism of LGZG in clinical setting.A randomized,double-blinded,placebo-controlled trial was performed.A total of 243 eligible participants with NAFLD were equally allocated to receive LGZG(two groups:standard dose and low dose)or placebo for 12 weeks on the basis of lifestyle modifications.The primary efficacy variable was homeostasis model assessment of insulin resistance(HOMA-IR).Analyses were performed in two populations in accordance with body mass index(BMI;overweight/obese,BMI 24 kg/m^(2);lean,BMI<24 kg/m^(2)).For overweight/obese participants,low-dose LGZG significantly decreased their HOMA-IR level compared with placebo(0.19(1.47)versus 0.08(1.99),P=0.038).For lean subjects,neither dose of LGZG showed a superior effect compared with placebo.Methylated DNA immunoprecipitation sequencing and real-time qPCR found that the DNA N6-methyladenine modification levels of protein phosphatase 1 regulatory subunit 3A(PPP1R3A)and autophagy related 3(ATG3)significantly increased after LGZG intervention in overweight/obese population.Low-dose LGZG effectively improved insulin resistance in overweight/obese subjects with NAFLD.The underlying mechanism may be related to the regulation of DNA N6-methyladenine modification of PPP1R3A and ATG3.Lean subjects may not be a targeted population for LGZG. | Liang Dai Jingjuan Xu Baocheng Liu Yanqi Dang Ruirui Wang Lijie Zhuang Dong Li Lulu Jiao Jianying Wang Lei Zhang Linda LDZhong Wenjun Zhou Guang Ji | 2022 | Frontiers of Medicine2022,16,5: | 7 |
| 7 | Ultrasound-triggered noninvasive regulation of blood glucose levels using microgels integrated with insulin nanocapsules显示文摘Diabetes is a serious public health problem affecting 422 million people worldwide. Traditional diabetes management often requires multiple daily insulin injections, associated with pain and inadequate glycemia control. Herein, we have developed an ultrasound-triggered insulin delivery system capable of pulsatile insulin release that can provide both long-term sustained and fast on-demand responses. In this system, insulin-loaded poly(lactic-co-glycolic acid) (PLGA) nanocapsules are encapsulated within chitosan microgels. The encapsulated insulin in nanocapsules can passively diffuse from the nanoparticle but remain restricted within the microgel. Upon ultrasound treatment, the stored insulin in microgels can be rapidly released to regulate blood glucose levels. In a chemically-induced type 1 diabetic mouse model, we demonstrated that this system, when activated by 30 s ultrasound administration, could effectively achieve glycemic control for up to one week in a noninvasive, localized, and pulsatile manner. | Jin Di Jicheng Yu Qun Wang Shanshan Yao Yanqi Ye Matthew Pless Yong Zhu Yun Jing Zhen Gu | 2017 | Nano Research2017,10,4: | 6 |
| 8 | Graphene/phosphorene nano-heterojunction:facile synthesis, nonlinear optics, and ultrafast photonics applications with enhanced performance显示文摘Owing to its thickness-modulated direct energy band gap, relatively strong light–matter interaction, and unique nonlinear optical response at a long wavelength, few-layer black phosphorus, or phosphorene, becomes very attractive in ultrafast photonics applications. Herein, we synthesized a graphene/phosphorene nano-heterojunction using a liquid phase-stripping method. Tiny lattice distortions in graphene and phosphorene suggest the formation of a nano-heterojunction between graphene and phosphorene nanosheets. In addition, we systematically investigate their nonlinear optical responses at different wavelength regimes. Our experiments indicate that the combined advantages of ultrafast relaxation, broadband response in graphene, and the strong light–matter interaction in phosphorene can be combined together by nano-heterojunction. We have further fabricated two-dimensional(2D) nano-heterojunction based optical saturable absorbers and integrated them into an erbium-doped fiber laser to demonstrate the generation of a stable ultrashort pulse down to 148 fs. Our results indicate that a graphene/phosphorene nano-heterojunction can operate as a promising saturable absorber for ultrafast laser systems with ultrahigh pulse energy and ultranarrow pulse duration. We believe this work opens up a new approach to designing 2D heterointerfaces for applications in ultrafast photonics and other research.The fabrication of a 2D nano-heterojunction assembled from stacking different 2D materials, via this facile and scalable growth approach, paves the way for the formation and tuning of new 2D materials with desirable photonic properties and applications. | SHUNXIANG LIU ZHONGJUN LI YANQI GE HUIDE WANG RUI YUE XIANTAO JIANG JIANQING LI QIAO WEN HAN ZHANG | 2017 | Photonics Research2017,5,6: | 6 |
| 9 | Tuning the selectivity of photoreduction of CO2 to syngas over Pd/layered double hydroxide nanosheets under visible light up to 600 nm显示文摘Photocatalytic reduction of CO2 with H2 O to syngas is an effective way for producing high value-added chemical feedstocks such as methanol and light olefins in industry.Nevertheless,the precise control of CO/H2 ratio from photocatalytic CO2 reduction reaction still poses a great challenge for the further application.Herein,we prepared a series of highly efficient heterostructure based on highly dispersed palladium supported on ultrathin Co Al-layered double hydroxide(LDH).In conjunction with a Ru-complex sensitizer,the molar ratios of CO/H2 can be tuned from 1:0.74 to 1:3 under visible-light irradiation(λ>400 nm).More interestingly,the syngas can be obtained under light irradiation atλ>600 nm.Structure characterization and density functional theory calculations revealed that the remarkable catalytic activity can be due to the supported palladium,which improved the charge transfer efficiency.Meanwhile,more H atoms were used to generate H2 on the supported palladium for further tunable CO/H2 ratio.This work demonstrates a new strategy for harnessing abundant solar-energy to produce syngas from a CO2 feedstock. | Xian Wang Zelin Wang Ya Bai Ling Tan Yanqi Xu Xiaojie Hao Jikang Wang Abdul Hanif Mahadi Yufei Zhao Lirong Zheng Yu-Fei Song | 2020 | Journal of Energy Chemistry2020,29,7: | 5 |
| 10 | Design and performance of dual-band high temperature superconducting filter显示文摘In this paper,a dual-band high temperature superconducting (HTS) filter with 14-pole and 3 cross couplings is presented.The equivalent model,theoretical result,coupling matrix,and the simulated result of the filter are demonstrated.The desired filter is designed and fabricated using double-sided DyBa 2 Cu 3 O 7 thin films on MgO wafer 2 inches in diameter and 0.5 mm in thickness.The filter has two passbands with frequencies 1920-1940 MHz and 1960-1980 MHz respectively,and insertion loss less than 0.2 dB.The measurement results show that the response of practical filters is in good agreement with that of simulated results and theoretical analysis,with the group delay variation being less than ±20 ns over 90% of the filter bandwidth for the two passbands. | JI LaiYun MA Jie SUN Jun WANG Lang LI YanQi LIU Bin | 2012 | Science China(Information Sciences)2012,55,4: | 5 |
| 11 | Ultrafast nonlinear absorption and nonlinear refraction in few-layer oxidized black phosphorus显示文摘We experimentally investigated the nonlinear optical response in few-layer oxidized black phosphorus(OBP) by the femtosecond Z-scan measurement technique, and found that OBP not only possesses strong ultrafast saturable absorption but also a nonlinear self-defocusing effect that is absent in black phosphorus(BP). The saturable absorption property originates mainly from the direct band structure, which is still maintained in OBP. The emergence of self-defocusing might originate from the combined consequences of the oxygen-induced defects in BP. Our experimental findings might constitute the first experimental evidence on how to dynamically tune its nonlinear property, offering an inroad in tailoring its optical properties through chemical modification(oxidation, introducing defects, etc.). The versatile ultrafast nonlinear optical properties(saturable absorption and self-defocusing) imply a significant potential of the layered OBP in the development of unprecedented optoelectronic devices, such as mode lockers, optical switches, laser beam shapers, and wavelength converters. | Shunbin Lu Yanqi Ge Zhengbo Sun Zongyu Huang Rui Cao Chujun Zhao Shuangchun Wen Dianyuan Fan Jianqing Li Han Zhang | 2016 | Photonics Research2016,4,6: | 5 |

| 13 | Superior anti-corrosion and self-healing bi-functional polymer composite coatings with polydopamine modified mesoporous silica/graphene oxide显示文摘In this article,graphene oxide(GO)and benzotriazole-loaded mesoporous silica nanoparticles(BTA/MSNs)are combined on micro scale through the in situ polymerization of polydopamine(PDA),preparing a selfhealing bi-functional GO(fGO)used as nano-fillers for anti-corrosion enhancement of waterborne epoxy(WEP)coatings.Scanning electronic microscopy(SEM)images show that the BTA/MSNs are uniformly distributed on the surface of high aspect ratio GO nanosheets to endow GO nanocontainer characteristics.UV-vis profiles demonstrate that fGO has p H-controlled release function.Modulus at lowest frequency is generally used for comparing the corrosion resistance of organic coatings.Modulus at lowest frequency(1.42×10^(5)Ωcm^(2))after 30 days immersion in 3.5 wt.%Na Cl solution revealed 2 orders of magnitude higher that of blank WEP(1.17×10^(7)Ωcm^(2)).With artificial cracks on its coatings,fGO/WEP had no obvious rust compared with blank WEP after 240 h of immersion.We anticipate that self-healing and physical barrier bi-functional nanocontainers improve the traditional anticorrosion coating efficiency with better,longer-lasting performance for shipping,oil drilling or bridge maintenance. | Yanqi Ma Haowei Huang Hongda Zhou Michael Graham James Smith Xinxin Sheng Ying Chen Li Zhang Xinya Zhang Elena Shchukina Dmitry Shchukin | 2021 | Journal of Materials Science & Technology2021,,36: | 4 |
| 14 | Evaluation of human epidermal growth factor receptor 2 status of breast cancer using preoperative multidetector computed tomography with deep learning and handcrafted radiomics features显示文摘Objective:To evaluate the human epidermal growth factor receptor 2(HER2)status in patients with breast cancer using multidetector computed tomography(MDCT)-based handcrafted and deep radiomics features.Methods:This retrospective study enrolled 339 female patients(primary cohort,n=177;validation cohort,n=162)with pathologically confirmed invasive breast cancer.Handcrafted and deep radiomics features were extracted from the MDCT images during the arterial phase.After the feature selection procedures,handcrafted and deep radiomics signatures and the combined model were built using multivariate logistic regression analysis.Performance was assessed by measures of discrimination,calibration,and clinical usefulness in the primary cohort and validated in the validation cohort.Results:The handcrafted radiomics signature had a discriminative ability with a C-index of 0.739[95%confidence interval(95%CI):0.661-0.818]in the primary cohort and 0.695(95%CI:0.609-0.781)in the validation cohort.The deep radiomics signature also had a discriminative ability with a C-index of 0.760(95%CI:0.690-0.831)in the primary cohort and 0.777(95%CI:0.696-0.857)in the validation cohort.The combined model,which incorporated both the handcrafted and deep radiomics signatures,showed good discriminative ability with a C-index of 0.829(95%CI:0.767-0.890)in the primary cohort and 0.809(95%CI:0.740-0.879)in the validation cohort.Conclusions:Handcrafted and deep radiomics features from MDCT images were associated with HER2 status in patients with breast cancer.Thus,these features could provide complementary aid for the radiological evaluation of HER2 status in breast cancer. | Xiaojun Yang Lei Wu Ke Zhao Weitao Ye Weixiao Liu Yingyi Wang Jiao Li Hanxiao Li Xiaomei Huang Wen Zhang Yanqi Huang Xin Chen Su Yao Zaiyi Liu Changhong Liang | 2020 | Chinese Journal of Cancer Research2020,32,2: | 4 |
| 15 | Hepatic encephalopathy complicated with hyponatremia and acid-base disturbance and its prognosis显示文摘Objective:To improve the diagnosis and therapeutic effect of occurrence and development of hyponatremia and disorder of acid-base balance among patients with hepatic encephalopathy(HE) by elucidating the regularity and mechanism,as well as its influence on prognosis.Methods:327 HE patients admitted to our hospital from January 1990 to June 2010 were enrolled.Meanwhile 316 patients hospitalized in the medical department of the same hospital were chosen as the control group.Patients in both groups were given the same methods to measure arterial blood gas parameters(pH value,PaCO2,[HCO3-],TCO2,BE and SaO2),blood biochemistry([Na+],[K+],[Cl-]),liver function,kidney function and blood glucose,serum sodium,and thereupon tocalculate the anion gap(AG) and the potential [HCO3-],and acid-base balance disorder.Results:Among the 327 HE patients,hyponatremia was found in 188 cases(57.4%),of whom 132 patients died(70.2%).While among the 316 patients in control group,68 presented with hyponatremia(21.5%),and 19 died(27.9%).The incidence and mortality were significantly different between the two groups(P<0.001).All the 327 patients presented with different degrees of acid-base balance disorder and 178 died(54.4%),in whom 164(50.2%) belonged to simple acid-base balance disorder and 74(45.1%) died,136(41.6%) were dual acid-base balance disorder and 80(58.8%) died,27(8.2%) were triple acid-base disturbance and 24(88.9%) died.Whereas in the control group only 83 patients(26.2%) were recognized as simple and dual acid-base balance disorder,and 18(21.7%) died.There was higher incidence of acid-base balance disorder and mortality rate in HE group than control one(P<0.001).Conclusion:Hyponatremia is valuable to judge HE patients' prognosis.The key parameters in the judgment and evaluation on acid-base balance disorder among HE patients are the change of pH values and serum electrolyte values.When pH value ≤ 7.30 or > 7.55,it generally suggests a poor prognosis. | Ren Chengshan Wang Lei Zhao Xiaoyan Yang Shiming Zhang Yanqi Wang Xiwen Bo Jianying Zhang Pengbin Guo Hong Ling Xianlong Li Yihui Da Siping Xie Xia Ren Wei Li Chunhua Qian Guisheng | 2012 | Journal of Medical Colleges of PLA(China)2012,27,3: | 3 |
| 16 | Real-time Dispatchable Region of Renewable Generation Constrained by Reactive Power and Voltage Profiles in AC Power Networks显示文摘A large amount of renewable energy generation(REG)has been integrated into power systems,challenging the operational security of power networks.In a real-time dispatch,system operators need to estimate the ability of the power network to accommodate REG with a limited reserve capacity.The real-time dispatchable region(RTDR)is defined as the largest range of a power injection that the power network can accommodate in a certain dispatch interval for a given dispatch base point.State-of-the-art research on the RTDR adopts a DC power flow model regardless of the voltage profiles and reactive power,which can overlook potentially insecure operational states of the system.To address this issue,this paper proposes an AC power flow based RTDR model simultaneously considering the reactive power and voltage profiles constraints.The nonlinear constraints in our model are approximated using a linear power flow model together with a polytope approximation technique for quadratic constraints.An adaptive constraint generation algorithm is used to calculate the RTDR.Simulation results using the IEEE 5-bus and 30-bus systems illustrate the advantages of the proposed model. | Yanqi Liu Zhigang Li Q.H.Wu Haibo Zhang | 2020 | CSEE Journal of Power and Energy Systems2020,6,3: | 3 |
| 17 | A radiomics prognostic scoring system for predicting progression-free survival in patients with stageⅣnon-small cell lung cancer treated with platinum-based chemotherapy显示文摘Objective:To develop and validate a radiomics prognostic scoring system(RPSS)for prediction of progressionfree survival(PFS)in patients with stageⅣnon-small cell lung cancer(NSCLC)treated with platinum-based chemotherapy.Methods:In this retrospective study,four independent cohorts of stageⅣNSCLC patients treated with platinum-based chemotherapy were included for model construction and validation(Discovery:n=159;Internal validation:n=156;External validation:n=81,Mutation validation:n=64).First,a total of 1,182 three-dimensional radiomics features were extracted from pre-treatment computed tomography(CT)images of each patient.Then,a radiomics signature was constructed using the least absolute shrinkage and selection operator method(LASSO)penalized Cox regression analysis.Finally,an individualized prognostic scoring system incorporating radiomics signature and clinicopathologic risk factors was proposed for PFS prediction.Results:The established radiomics signature consisting of 16 features showed good discrimination for classifying patients with high-risk and low-risk progression to chemotherapy in all cohorts(All P<0.05).On the multivariable analysis,independent factors for PFS were radiomics signature,performance status(PS),and N stage,which were all selected into construction of RPSS.The RPSS showed significant prognostic performance for predicting PFS in discovery[C-index:0.772,95%confidence interval(95%CI):0.765-0.779],internal validation(C-index:0.738,95%CI:0.730-0.746),external validation(C-index:0.750,95%CI:0.734-0.765),and mutation validation(Cindex:0.739,95%CI:0.720-0.758).Decision curve analysis revealed that RPSS significantly outperformed the clinicopathologic-based model in terms of clinical usefulness(All P<0.05).Conclusions:This study established a radiomics prognostic scoring system as RPSS that can be conveniently used to achieve individualized prediction of PFS probability for stageⅣNSCLC patients treated with platinumbased chemotherapy,which holds promise for guiding personalized pre-therapy of stageⅣNSCLC. | Lan He Zhenhui Li Xin Chen Yanqi Huang Lixu Yan Changhong Liang Zaiyi Liu | 2021 | Chinese Journal of Cancer Research2021,33,5: | 3 |

| 20 | Shape-controlled synthesis of liquid metal nanodroplets for photothermal therapy显示文摘The capping agents for liquid metal (LM) nanodroplets in aqueous solutions are restricted to thiol-containing and positively-charged molecules or macromolecules.However,both thiolate-metal complex and electrostatic interaction are liable to detachment upon strong mechanical forces such as sonication,leading to limited stability and applications.To address this,we utilized ultrasmall water soluble melanin nanoparticles (MNPs) as the capping agent,which exhibited strong metal binding capability with the oxide layer of gallium based LMs and resulted in enhanced stability.Interestingly,shape-controlled synthesis of LM nanodroplets can be achieved by the incorporation of MNPs.Various EGaln nanostructures including nanorice,nanosphere and nanorod were obtained by simply tuning the feed ratio,sonication time,and suspension temperature.Among these shapes,EGaln nanorice has the best photothermal conversion efficiency,which could be leveraged for photothermal therapy. | Junjie Yan Xudong Zhang Yang Liu Yanqi Ye Jicheng Yu Qian Chen Jinqiang Wang Yuqi Zhang Quanyin Hu Yang Kang Min Yang Zhen Gu | 2019 | Nano Research2019,12,6: | 2 |
