| 2 | Bevacizumab biosimilar LY01008 compared with bevacizumab(Avastin)as first-line treatment for Chinese patients with unresectable,metastatic,or recurrent non-squamous non-small-cell lung cancer:A multicenter,randomized,double-blinded,phase Ⅲ trial显示文摘Background:Previous studies have demonstrated the preclinical pharmacological and toxicological consistency,and clinical pharmacokinetic equivalence of bevacizumab biosimilar LY01008 with reference bevacizumab(Avastin).This randomized controlled trial aimed to compare the efficacy and safety of LY01008 with Avastin in first-line treatment of Chinese patients with advanced or recurrent non-squamous non-small cell lung cancer(NSCLC).Methods:StageⅢB-ⅣNSCLC patients with evaluable lesions,good physical status,and adequate organ functions from 67 centers across China were randomized in a ratio of 1:1 to receive LY01008 or Avastin 15 mg/kg intravenously in combination with paclitaxel/carboplatin(combined treatment)for 4-6 cycles,followed by maintenance monotherapy with LY01008 until disease progression,intolerable toxicity,or death.The primary endpoint was objective response rate(ORR)in accordance with Response Evaluation Criteria in Solid Tumors(RECIST)version 1.1 confirmed by independent radiological review committees(IRRC).Secondary endpoints included disease control rate(DCR),duration of response(DoR),progression-free survival(PFS),overall survival(OS),and safety.This study was registered in Clinical Trials.gov(NCT03533127).Results:Between December 15^(th),2017,and May 15^(th),2019,a total of 649 patients were randomized to the LY01008(n=324)or Avastin(n=325)group.As of September 25th,2019 for primary endpoint analysis,589 patients received ORR evaluation,with a median number of combined treatment cycles of 5(range 1-6)andmedian duration of treatment of 3.0(range 0.0-5.1)months.ORRof responseevaluable patients in the LY01008 and Avastin groups were 48.5% and 53.0%,respectively.The stratified ORR ratio was 0.91(90%CI 0.80-1.04,within the prespecified equivalence margin of 0.75-1.33).Up to May 15^(th),2020,with a median follow-up of 13.6(range 0.8-28.4)months,no notable differences in DCR,median DoR,median PFS,median OS,and 1-year OS rate were observed between the LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,or recurrent non-squamous NSCLC patients in the first-line setting. | Yuankai Shi Kaijian Lei Yuming Jia Bingqiang Ni Zhiyong He Minghong Bi Xicheng Wang Jianhua Shi Ming Zhou Qian Sun Guolei Wang Dongji Chen Yongqian Shu Lianke Liu Zhongliang Guo Yong Liu Junquan Yang Ke Wang Ke Xiao LinWu Tienan Yi Debin Sun Mafei Kang Tianjiang Ma Yimin Mao Jinsheng Shi Tiegang Tang Yan Wang Puyuan Xing Dongqing Lv Wangjun Liao Zhiguo Luo Bin Wang Xiaohong Wu Xiaoli Zhu Shuhua Han Qisen Guo Rongyu Liu Zhiwei Lu Jianyong Zhang Jian Fang Changlu Hu Yinghua Ji Guolong Liu Hong Lu Dedong Wu Junhong Zhang Shuyang Zhu Zheng Liu Wensheng Qiu Feng Ye Yan Yu Yanqiu Zhao Qinhong Zheng Jun Chen Zhanyu Pan Yiping Zhang Wenjuan Lian Bo Jiang Bo Qiu Guojun Zhang Hua Zhang Yanju Chen Yuan Chen Hongbing Duan Manxiang Li Shengming Liu Lijun Ma Hongming Pan Xia Yuan Xueli Yuan Yulong Zheng Emei Gao Li Zhao Shumin Wang Can Wu | 2021 | Cancer Communications2021，41，9： | 5 |
| 3 | Thermal simulation experiment of organic matter-rich shale and implication for organic pore formation and evolution显示文摘A thermal simulation experiment of diagenesis,hydrocarbon generation and evolution of the organic matter-rich shale was carried out to investigate formation and evolution of organic pores under the constraint from immature,low mature,mature,high mature to overmature geological conditions.The argon ion polishingefield emission scanning electron microscope was used to analyze microscopic features of original samples and simulated samples of various evolution stages.Results showed organic pores could be formed during hydrocarbon generation from biochemical and hypothermal processes in the immature and low mature stages,and the shale shallow-buried depth might be favorable for preservation of organic pores;the generation and evolution of organic pores were of heterogeneity,and the maturity was not a decisive factor which controlled formation and development of organic pores,while the difference in physiochemical structure of organic matter played an important role in formation and evolution of organic pores;the organic pore development was obviously related with the retained oil,and the organic pores formed in the oil generation stage were easily filled by pyrolysis asphalt;organic contraction fractures/organic marginal pores might be important storage spaces for shale gas occurrence,and their development was mainly controlled by the physiochemical structure and evolution degree of organic matters when the chemical adsorbed organic matter was converted into the physical adsorbed organic matter and the free organic matter. | Zhongliang Ma Lunju Zheng Xuhui Xu Fang Bao Xiaolu Yu | 2017 | Petroleum Research2017，2，4： | 4 |

| 5 | Perspectives and challenges of hydrogen storage in solid-state hydrides显示文摘Hydrogen has been widely considered as a clean energy carrier that bridges the energy producers and energy consumers in an efficient and safe way for a sustainable society.Hydrogen can be stored in a gas,liquid and solid states and each method has its unique advantage.Though compressed hydrogen and liquefied hydrogen are mature technologies for industrial applications,appropriate measures are necessary to deal with the issues at high pressure up to around 100 MPa and low temperature at around 20 K.Distinct from those technologies,storing hydrogen in solid-state hydrides can realize a more compact and much safer approach that does not require high hydrogen pressure and cryogenic temperature.In this review,we will provide an overview of the majormaterial groups that are capable of absorbing and desorbing hydrogen reversibly.The main features on hydrogen storage properties of each material group are summarized,together with the discussion of the key issues and the guidance of materials design,aiming at providing insights for new material development as well as industrial applications. | Zhen Chen Zhongliang Ma Jie Zheng Xingguo Li Etsuo Akiba Hai-Wen Li | 2021 | Chinese Journal of Chemical Engineering2021，34，1： | 4 |
| 6 | Textbook Outcome as a measure of surgical quality assessment and prognosis in gastric neuroendocrine carcinoma:A large multicenter sample analysis显示文摘Objective:Quality assurance is crucial for oncological surgical treatment assessment.For rare diseases,singlequality indicators are not enough.We aim to develop a comprehensive and reproducible measurement,called the'Textbook Outcome'(TO),to assess the quality of surgical treatment and prognosis of gastric neuroendocrine carcinoma(G-NEC)patients.Methods:Data from patients with primary diagnosed G-NEC included in 24 high-volume Chinese hospitals from October 2005 to September 2018 were analyzed.TO included receiving a curative resection,≥15 lymph nodes examined,no severe postoperative complications,hospital stay≤21 d,and no hospital readmission≤30 d after discharge.Hospital variation in TO was analyzed using a case mix-adjusted funnel plot.Prognostic factors of survival and risk factors for non-Textbook Outcome(non-TO)were analyzed using Cox and logistic models,respectively.Results:TO was achieved in 56.6%of 860 G-NEC patients.TO patients had better overall survival(OS),disease-free survival(DFS),and recurrence-free survival(RFS)than non-TO patients(P<0.05).Moreover,TO patients accounted for 60.3%of patients without recurrence.Multivariate Cox analysis revealed non-TO as an independent risk factor for OS,DFS,and RFS of G-NEC patients(P<0.05).Increasing TO rates were associated with improved OS for G-NEC patients,but not hospital volume.Multivariate logistic regression revealed that nonlower tumors,open surgery,and>200 mL blood loss were independent risk factors for non-TO patients(P<0.05).Conclusions:TO is strongly associated with multicenter surgical quality and prognosis for G-NEC patients.Factors predicting non-TO are identified,which may help guide strategies to optimize G-NEC outcomes. | Qiyue Chen Zhongliang Ning Zhiyu Liu Yanbing Zhou Qingliang He Yantao Tian Hankun Hao Wei Lin Lixin Jiang Gang Zhao Ping Li Chaohui Zheng Changming Huang on behalf of the Study Group for Gastric Neuroendocrine Tumors | 2021 | Chinese Journal of Cancer Research2021，33，4： | 2 |
| 7 | Antihepatofibrotic effect of Guizhifuling pill(桂枝茯苓丸) on carbon tetrachloride-induced liver fibrosis in mice显示文摘OBJECTIVE: To evaluate the protective effects and the underlying mechanism of Guizhifuling pill(桂枝茯苓丸, GZFL) on carbon tetrachloride(CCl4)-induced hepatic fibrosis in mice. METHODS: Male ICR mice by intraperitoneally administered with 20% CCl4(mixed 1∶4 in soybean oil) to induce liver fibrosis. Mice that underwent CCl4 were orally with GZFL. Using hematoxylin and eosin and Masson staining to examine the pathological changes in liver tissue. Serum biochemical parameters, antioxidant enzyme activity and proinflammatory cytokines was assessed. Nuclear factor-kappa B(NF-κB) pathway and nuclear factor-erythroid 2-related factor 2(Nrf2) family members were evaluated by Western blotting. RESULTS: Our findings indicated that GZFL could effectively suppress the progression of liver fibrosis in mice, which was determined based on the improvement in liver function and reduction of collagen deposition. GZFL treatment also decreased the level of cytokines and increased the activity of antioxidant enzymes in liver tissue. Moreover, GZFL exerted anti-inflammatory and antioxidant effects through regulating the Nrf2-mediated antioxidant system and inhibiting the NF-κB pathway. CONCLUSIONS: GZFL may prevent the progression of liver fibrosis by regulating the Nrf2/heme oxygenase-1 and NF-κB signaling pathways, thereby highlighting its role in the management of liver fibrosis. | XU Baogui ZHENG Jiawen TIAN Xiaoxiao YUAN Falei LIU Zhongliang YANG Zuisu DING Xianjun | 2022 | Journal of Traditional Chinese Medicine2022，42，5： | 2 |
| 8 | Excellent light-capture capability of trilobal SiNW for ultra-high JSC in single-nanowire solar cells显示文摘Single-.nanowire solar cells with a unique light-concentration property are expected to exceed the Shockley-Queisser limit.The architecture of single nanowire is an important factor to regulate its optical performance.We designed a trilobal silicon nanowire(SiNW)with two cquivalent scales that possesses superior light-absorption efficiency in the whole wavelength range and shows good tolerance for incident angle.The electric field distribution in this geometry is concentrated in the blade with small equivalent scale and pivot with large equivalent scale,respectively,in the short wavelength range and long wavelength range.Corresponding good light absorption of trilobal SiNW in the two wavelength ranges leads to stronger total light absorption capacity than that of cylindrical SiNW.Trilobal single nanowire solar cells can obtain a short-circuit current density(JSC)of 647 mA·cm^2,which provides a new choice for designing single nanowire with excellent light-capture capability. | ZHONGLIANG GAO GUILU Lin YUPENG ZHENG NA SANG YINGFENG LI LEI CHEN MEICHENG LI | 2020 | Photonics Research2020，8，6： | 2 |
| 9 | Effect of a Hybrid Micro/Nano-integrated Titanium Surface on Behavior of Rat Osteoblasts显示文摘The objective of this study was to investigate the effect of a new combined micro/nanoscale implant surface feature on osteoblasts' behaviors including cell morphology, adhesion, proliferation, differentiation, and mineralization in vitro. A new micro/nano-hybrid topography surface was fabricated on commercial pure titanium(Cp Ti) by a two-step sandblasted acid-etching and subsequent alkali-and heattreatment(SA-AH). The conventional sandblasted/acid-etching(SA) treatment and alkali and heat(AH) treatment were also carried out on the Cp Ti as controls. Surface microstructures of the Ti disc samples were assessed by scanning electron microscopy(SEM). The neonatal rat calvaria-derived osteoblasts were seeded on these discs and the initial cell morphology was evaluated by SEM and immunofluorescence. Initial adhesion of the cells was then assayed by DAPI staining at 1, 2, and 4 h after seeding. The Cell Counting Kit-8(CCact K8) assay, gene expression of osteoblastic markers(ALP, Col 1, OCN, BSP, OSX, Cbfα1) and Alizarin Red S staining assays were monitored respectively for cell proliferations, differentiation and mineralization. The results show significant differences in osteoblast's behaviors on the four kinds of Ti surfaces. Compared with Cp Ti surface, the SA and AH treatment can significantly promote cell adhesion, differentiation and mineralization of osteoblasts. In particular, the combined SA and AH treatments exhibit synergistic effects in comparison with the treatment of SA and AH individually, and are more favorable for stimulating a series of osteogenous responses from cell adhesion to mineralization of osteoblasts. In summary, this study provides some new evidence that the integrated micro/nanostructure on the Cp Ti surface may promote bone osseointegration between the Ti implantbone interfaces in vitro. | 王朝南 冯彦博 WANG Dafeng ZHENG Yuanbo SU Zhongliang FU Jiaxing YANG Xianyan | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，2： | 1 |

| 12 | Unraveling the triplet excited-state dynamics of Bi^(3+)in vacancyordered double perovskite Cs_(2)SnCl_(6) nanocrystals显示文摘Luminescent metal halides doped with ns^(2-)metal ions such as 6s^(2-)metal Bi^(3+)have aroused reviving interest owing to their outstanding optical properties;however,the origin of the photoluminescence(PL)remains controversial and unclear.Herein,we report a strategy for the controlled synthesis of Bi^(3+)-doped vacancy-ordered double perovskite Cs_(2)SnCl_(6)nanocrystals(NCs)and unravel the triplet excited-state dynamics of Bi^(3+)through temperature-dependent PL and ultrafast femtosecond transient absorption spectroscopies.Owing to the aliovalent Bi^(3+)doping in the spatially confined zero-dimensional(0D)structure of Cs2SnCl6,Bi^(3+)ions experience an enhancive Jahn-Teller distortion in the excited state,which results in intense broadband blue PL originating from the inter-configurational 3P0,1→1S0 transitions of Bi^(3+)at 450 nm,with a large Stokes shift and a quantum yield of 35.2%.Specifically,an unusual thermal-enhanced Jahn-Teller splitting of the excitation band and a remarkable transition of the PL lifetime from ms at 10 K toμs at 300 K were observed,as solid evidence for the isolated Bi^(3+)emission.These findings clarify the controversy about the PL origin in ns^(2-)metal ion-doped lead-free luminescent metal halides,thereby paving the way for exploring their optoelectronic applications. | Mengyao Jin Wei Zheng Zhongliang Gong Ping Huang Renfu Li Jin Xu Xingwen Cheng Wei Zhang Xueyuan Chen | 2022 | Nano Research2022，15，7： | 1 |
| 13 | Occurrence Characteristics of Saline-Lacustrine Shale-Oil in the Qianjiang Depression,Jianghan Basin,Central China显示文摘The amount of shale oil and its characterization are key issues in the study of shale oil.At present,many scholars use a variety of methods to evaluate the amount of shale oil,and use the calculated amount of hydrocarbons to analyze its influencing factors;however,there is lack of detailed research on the storage space for shale-oil and it’s influencing factors.In view of this issue,gas chromatography(GC),gas chromatography-mass spectrometry(GC-MS),soxhlet extraction(SE),fieldemission scanning electron microscopy(FE-SEM),low-temperature nitrogen adsorption(LTNA),highpressure mercury intrusion(HPMI),and X-ray diffraction(XRD)were used to analyze and compare samples from two wells located in different deposition locations.The unconventional Well BYY2 and BX7 s were drilled in the depocenter and distal area of the Qianjiang Formation,respectively.Controlled by differences in the organic matter type and sedimentary environment,the organic matter in Well BYY2,which was found to be characterized by laminar shale,mainly originated from aquatic algae.The results showed that as the total organic carbon(TOC)content increased,the amount of shaleoil in the pores increased.Shale-oil was mostly stored in mesopores and macropores that had been preserved by dolomite minerals of a biogenic origin and also occurred in pores sized 5–200 nm and>1μm.Dolomite minerals of a biogenic origin and clay minerals contributed to the occurrence of shaleoil.In comparison,the organic matter in Well BX7 has been greatly influenced by terrestrial organic matter.Pores in the massive mudstones from Well BX7 were determined to be mainly mesopores preserved by clay minerals and quartz,and the shale-oil was mostly stored within the pores of<40 nm.When the TOC content was~2.5 wt.%,the generated shale-oil reached saturation.Clay minerals contributed to the occurrence of shale-oil,whereas quartz only contributed to the occurrence of shale-oil in macropores. | Zhongliang Sun Zhiliang He Furong Wang Yuanjia Han Sheng He Yuguang Hou Jing Luo Youheng Zheng Shiqiang Wu | 2022 | Journal of Earth Science2022，33，4： | 1 |

| 18 | Effect of Shale Reservoir Characteristics on Shale Oil Movability in the Lower Third Member of the Shahejie Formation, Zhanhua Sag显示文摘To reveal the effect of shale reservoir characteristics on the movability of shale oil and its action mechanism in the lower third member of the Shahejie Formation(Es3l), samples with different features were selected and analyzed using N2 adsorption, high-pressure mercury injection capillary pressure(MICP), nuclear magnetic resonance(NMR), high-speed centrifugation, and displacement image techniques. The results show that shale pore structure characteristics control shale oil movability directly. Movable oil saturation has a positive relationship with pore volume for radius > 2 μm, as larger pores often have higher movable oil saturation, indicating that movable oil is present in relatively larger pores. The main reasons for this are as follows. The relatively smaller pores often have oil-wetting properties because of organic matter, which has an unfavorable effect on the flow of oil, while the relatively larger pores are often wetted by water, which is helpful to shale oil movability. The rich surface provided by the relatively smaller pores is beneficial to the adsorption of immovable oil. Meanwhile, the relatively larger pores create significant pore volume for movable oil. Moreover, the larger pores often have good pore connectivity. Pores and fractures are interconnected to form a complex fracture network, which provides a good permeability channel for shale oil flow. The smaller pores are mostly distributed separately;thus, they are not conducive to the flow of shale oil. The mineral composition and fabric macroscopically affect the movability of shale oil. Calcite plays an active role in shale oil movability by increasing the brittleness of shale and is more likely to form micro-cracks under the same stress background. Clay does not utilize shale oil flow because of its large specific surface area and its block effect. The bedding structure increases the large-scale storage space and improves the connectivity of pores at different scales, which is conducive to the movability of shale oil. | NING Chuanxiang MA Zhongliang JIANG Zhenxue SU Siyuan LI Tingwei ZHENG Lunju WANG Guozhen LI Fengxun | 2020 | Acta Geologica Sinica(English Edition)2020，94，2： | 0 |
| 19 | Modulator-directed assembly of hybrid composites based on metalorganic frameworks and upconversion nanoparticles显示文摘Hybrid composites made of metal-organic frameworks(MOFs)and lanthanide-doped upconversion nanoparticles(UCNPs)have attracted considerable interest for their synergistically enhanced functions in various applications such as chemical sensing,photocatalysis,anticounterfeiting and nanomedicine.However,precise assembly of MOF/UCNP hybrid composites with tunable morphologies remains a challenge due to the lack of effective synthetic methods and fundamental understanding of the growth mechanisms.Herein,we propose a modulator-directed assembly strategy to synthesize a series of ZIF-8@UCNP composites(ZIF-8=zeolitic imidazolate framework-8).The UCNPs densely paved on the surface of ZIF-8 microcrystals and endowed the composites with intense upconversion blue emission,which were verified by steady-state/transient photoluminescence(PL)spectroscopy and single-particle imaging.Ethylenediamine(EDA)was firstly used as a modulator to fine-tune the predominant MOF facets and realized distinct morphologies of the composites.By adjusting the concentration of EDA from 0 to 25 mmol/L,the morphology of the ZIF-8@UCNP composites was tuned from rhombic dodecahedron(RD)to truncated rhombic dodecahedron(TRD),cube with truncated edges(CTE),cube,and finally a unique form of interpenetration twins(IT).The nucleation and growth process of the ZIF-8@UCNP composites was monitored by time-dependent scanning electron microscopy(SEM)images and the formation mechanism was thoroughly revealed.Furthermore,we demonstrated that the strategy for assembly of morphology-controllable ZIF-8@UCNP composites was generally applicable to various UCNPs with different sizes and shapes.The proposed strategy is expected to open up new avenues for the controllable synthesis of MOF/UCNP composites toward diverse applications. | Yanhui Feng Xingjun Li Shan Lu Renfu Li Zhongliang Gong Xiaoying Shang Yifan Pei Wei Zheng Datao Tu Xueyuan Chen | 2023 | Nano Research2023，16，1： | 0 |
