| 1 | Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy. | Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen | 2021 | Cancer Communications2021，41，11： | 29 |
| 2 | Influence of temperature and solution composition on the formation of calcium sulfates显示文摘Calcium sulfates (anhydrite and hydrates) were synthesized by mixing CaCl 2 and Na 2 SO 4 solutions at room temperature followed by aging the resulting slurries at elevated temperatures. The variation of the morphology and structure of the calcium sulfates with aging temperature was investigated. Experimental results indicated that CaSO 4 ·2H 2 O plates, CaSO 4 ·0.5H 2 O whiskers and CaSO 4 spindles were formed at ≤100 °C, 130–160 °C and ≥170 °C, respectively. The formation and conversion of the calcium sulfates were discussed on the basis of characterization of the products and chemical analysis of the solutions. Compared to NaCl solution, pure water favors one-dimensional hydrothermal growth of CaSO 4 ·0.5H 2 O whiskers owing to lower supersaturation. | Kangbi Luo Chunmei Li Lan Xiang Huping Li Ping Ning | 2010 | Particuology2010，8，3： | 26 |

| 4 | Spore-pollen-climate factor transfer function and paleoenvironment reconstruction in Dajiuhu,Shennongjia,Central China显示文摘The identified results of 121 surface sediment spore-pollen samples in Shennongjia and meteorological data base of 30 years(January,1971―December,2000)of 7 meteorological stations around Dajiuhu, Shennongjia are used in this study.Selecting 55 species of common spore-pollen with the method of space fitting and stepwise regression we construct the pollen climate factor transfer function of annual mean tem- perature:T=7.649-2.33097X Abies -0.10873X Betula -0.17352X Compositae -0.13176X Cruciferae +0.13356XEuphorbiaceae -0.83069X Campanulaceae +1.96494XPyrrosia+0.38411XPteris+2.77741XSelaginella+0.04439XMonolites.We had reconstructed annual mean temperature series by use of the sporo-pollen samples concentra-tion percentage in peat section with 297 cm thickness in Dajiuhu since 15.753 kaBP.The temperature series reflect well the character of climatic change since the late glacial,which indicates extreme cold climate event of the Oldest Dryas,the Older Dryas,the Younger Dryas and the 8.2 kaBP,the same to the climate fluctuations of Bolling Warm Period and Allerod Warm Period,and the character of temperature change fluctuating frequently at the transition age from the late glacial to the Holocene.The reconstructed temperature also indicate Holocene Optimum,late Holocene warm-dry climate,and the character of climatic change in Dajiuhu in the last 1 ka.The conclusion is that the sporo-pollen samples have important climatic significance to surface sediment and the section of Dajiuhu,Shennongjia and important reference value to studying climatic change during the last glaciation by the temperature transfer function and reconstructed temperature series. | ZHU Cheng CHEN Xing ZHANG GuangSheng MA ChunMei ZHU Qing LI ZhongXuan XU WeiFeng | 2008 | Chinese Science Bulletin2008，53，S1： | 15 |
| 5 | Climate and environment reconstruction during the Medieval Warm Period in Lop Nur of Xinjiang, China显示文摘We made multi-proxy analysis of 14C, grain size, microfossils, plant seeds, and geochemical elements on samples from a profile in the central West Lake of Lop Nur. The grain size suggests relatively stable sedimentary environment around the Medieval Warm Period (MWP) with weak storm effect, which is followed by frequent strong storm events. Abundant microfossils and plant seeds in this stage indicate a warm and humid fresh to brackish lake environment. C, N, and stable elements are high in content in the sediments while Rb/Sr, Ba/Sr, and Ti/Sr are in a steady low level. In addition, plenty of red willows lived here prior to about 700 a B.P., indicating a favorable environmental condition. The results indicate that the environment in Lop Nur and its west bank turned to be favorable at about 2200 a B.P., where the Loulan Culture began to thrive. Then the climate and environment came to be in the good condition in the Tang and Song Dynasties, when the storm effect became weaker, rainfall increased and the salty lake water turned to be brackish to fresh lake water. Hence, limnic biomass increased with higher species diversity. | MA ChunMei WANG FuBao CAO QiongYing XIA XunCheng LI ShengFeng Li XuSheng | 2008 | Chinese Science Bulletin2008，53，19： | 13 |
| 6 | Complement 5a receptor-mediated neutrophil dysfunction is associated with a poor outcome in sepsis显示文摘补充 5a (C5a ) 被导致 neutrophils 的功能的缺陷在败血的致病含有;然而, C5a 受体的用途(C5aRs;C5aR 和 C5L2 ) 因为为败血的管理的 biomarkers 是不明确的。这研究在嗜中性的功能上在 neutrophils 和他们的效果上调查了 C5aR 和 C5L2 的动态表示。我们发现败血病人与健康、全身的煽动性的反应相比在 neutrophils 上显示了 C5aR 和 C5L2 的低表示层次症候群(先生) 题目,和这个表示模式与疾病严厉被相关。另外, C5aR 和 C5L2 的表示层次与败血病人的幸存被联系。在 vitro, C5a 的增加显著地从败血病人在 neutrophils 减少了 C5aR 和 C5L2 表示层次和 IL-8 生产。那些调查结果建议 C5aRs 的减少的表示为败血病人与 neutrophils 和差的预后的功能的缺陷被联系。总的来说,这些调查结果可以帮助作为早标记建立 C5aRs 表示层次预言败血的严厉。 | Ruonan Xu Fang Lin Chunmei Bao Huihuang Huang Chengcheng Ji Siyu Wang Lei Jin Lijian Sun Ke Li Zheng Zhang Fu-Sheng Wang | 2016 | Cellular & Molecular Immunology2016，13，1： | 10 |
| 7 | Intermetallic phase formation and evolution during homogenization and solution in Al-Zn-Mg-Cu alloys显示文摘The effects of major alloy element contents of Zn,Mg,Cu in Al-Zn-Mg-Cu alloys on the formation and evolution of intermetallic phases during casting,homogenization and solution treatment have been investigated through using X-ray diffraction,scanning electron microscopy and differential scanning calorimetry.Experimental results showed that a relatively higher Zn content with lower Mg and Cu contents was beneficial to the formation of MgZn2phase instead of the Al2CuMg phase,which resulted in the unicity of the intermetallics in the Al matrix,and that the MgZn2phase was easier for diffusion and dissolution during homogenization and solution than the Al2CuMg phase.Additionally,the results of the first-principles calculations gave support for explaining the experimental phenomena.A larger absolute value of formation enthalpy and a smaller value of binding energy of the MgZn2phase,as compared with the Al2CuMg phase,give it priority to precipitate during casting and make it easier to re-dissolve during homogenization and solution treatment.What’s more,higher elastic constants with severe anisotropy of Young’s modulus make undissolved blocks of Al2CuMg phase act as crack initiation,which degrade the performance of the materials. | LI ChunMei CHEN ZhiQian ZENG SuMin CHENG NanPu CHEN TianXiao | 2013 | Science China(Technological Sciences)2013，56，11： | 10 |
| 8 | Type I interferons promote the survival and proinflammatory properties of transitional B cells in systemic lupus erythematosus patients显示文摘A hallmark of systemic lupus erythematosus(SLE)is the breaking of B-cell tolerance with the generation of high-affinity autoantibodies;however,the antibody-independent features of the B-cell compartment in SLE are less understood.In this study,we performed an extensive examination of B-cell subsets and their proinflammatory properties in a Chinese cohort of new-onset SLE patients.We observed that SLE patients exhibited an increased frequency of transitional B cells compared with healthy donors and rheumatoid arthritis patients.Plasma from SLE patients potently promoted the survival of transitional B cells in a type I IFN-dependent manner,which can be recapitulated by direct IFN-αtreatment.Furthermore,the effect of IFN-αon enhanced survival of transitional B cells was associated with NF-κB pathway activation and reduced expression of the pro-apoptotic molecule Bax.Transitional B cells from SLE patients harbored a higher capacity to produce proinflammatory cytokine IL-6,which was also linked to the overactivated type I IFN pathway.In addition,the frequency of IL-6-producing transitional B cells was positively correlated with disease activity in SLE patients,and these cells were significantly reduced after short-term standard therapies.Thus,the current study provides a direct link between type I IFN pathway overactivation and the abnormally high frequency and proinflammatory properties of transitional B cells in active SLE patients,which contributes to the understanding of the roles of type I IFNs and B cells in the pathogenesis of SLE. | Mei Liu Qiang Guo Chunmei Wu Delphine Sterlin Shyamal Goswami Ying Zhang Teng Li Chunde Bao Nan Shen Qiong Fu Xiaoming Zhang | 2019 | Cellular & Molecular Immunology2019，16，4： | 9 |

| 10 | Terahertz surface plasmonic waves: a review显示文摘Terahertz science and technology promise many cutting-edge applications.Terahertz surface plasmonic waves that propagate at metal–dielectric interfaces deliver a potentially effective way to realize integrated terahertz devices and systems.Previous concerns regarding terahertz surface plasmonic waves have been based on their highly delocalized feature.However,recent advances in plasmonics indicate that the confinement of terahertz surface plasmonic waves,as well as their propagating behaviors,can be engineered by designing the surface environments,shapes,structures,materials,etc.,enabling a unique and fascinating regime of plasmonic waves.Together with the essential spectral property of terahertz radiation,as well as the increasingly developed materials,microfabrication,and time-domain spectroscopy technologies,devices and systems based on terahertz surface plasmonic waves may pave the way toward highly integrated platforms for multifunctional operation,implementation,and processing of terahertz waves in both fundamental science and practical applications.We present a review on terahertz surface plasmonic waves on various types of supports in a sequence of properties,excitation and detection,and applications.The current research trend and outlook of possible research directions for terahertz surface plasmonic waves are also outlined. | Xueqian Zhang Quan Xu Lingbo Xia Yanfeng Li Jianqiang Gu Zhen Tian Chunmei Ouyang Jiaguang Han Weili Zhang | 2020 | Advanced Photonics2020，2，1： | 7 |
| 11 | The R2R3-MYB transcription factor GhMYB1a regulates flavonol and anthocyanin accumulation in Gerbera hybrida显示文摘Anthocyanins and flavonols have vital roles in flower coloration,plant development,and defense.Because anthocyanins and flavonols share the same subcellular localization and common biosynthetic substrates,these pathways may compete for substrates.However,the mechanism regulating this potential competition remains unclear.Here,we identified GhMYB1a,an R2R3-MYB transcription factor involved in the regulation of anthocyanin and flavonol accumulation in gerbera(Gerbera hybrida).GhMYB1a shares high sequence similarity with that of other characterized regulators of flavonol biosynthesis.In addition,GhMYB1a is also phylogenetically grouped with these proteins.The overexpression of GhMYB1a in gerbera and tobacco(Nicotiana tabacum)resulted in decreased anthocyanin accumulation and increased accumulation of flavonols by upregulating the structural genes involved in flavonol biosynthesis.We further found that GhMYB1a functions as a homodimer instead of interacting with basic helix-loop-helix cofactors.These results suggest that GhMYB1a is involved in regulating the anthocyanin and flavonol metabolic pathways through precise regulation of gene expression.The functional characterization of GhMYB1a provides insight into the biosynthesis and regulation of flavonols and anthocyanins. | Chunmei Zhong Yi Tang Bin Pang Xukun Li Yuping Yang Jing Deng Chengyong Feng Lingfei Li Guiping Ren Yaqin Wang Jianzong Peng Shulan Sun Shan Liang Xiaojing Wang | 2020 | Horticulture Research2020，7，1： | 7 |
| 12 | Rapid detection of pesticide residues in Chinese herbal medicines by molecularly imprinted membrane electrospray ionization mass spectrometry显示文摘Chinese herbal medicines(CHMs)play an increasingly important role in the field of medicine and affects public health in the world.Although more and more strict has been employed to ensure the quality and safety of CHMs,pesticide residues in CHMs remain a serious issue and are the bottleneck for the global development of CHMs.In this work,we applied molecularly imprinted membrane electrospray mass spectrometry(MIM-ESI MS)for rapid detecting 4 classes of pesticide residues in CHMs,including organophosphorus(OPP),carbamates,pyrethroids and neonicotinoids in CHMs.Compared with our previous ambient ionization method MESI,MIM-ESI is capable of achieving a~50-fold increase in the detection limit of conventional analytical methods owing to the specificity recognition and unique enrichment of MIM.The optimal experimental conditions were determined,and the method was further validated for its sensitivity and specificity.Our data showed that MIM-ESI MS is applicable for the direct quantitation of pesticide residues in CHMs.This detection technology may help to ensure the quality of CHMs in the future. | Chunmei Wu Tianyi Li Dongju Li Shanshan Jia Jianmei Huang Haimin Lei Mei Zhang | 2021 | Chinese Chemical Letters2021，32，7： | 6 |
| 13 | Reliability analysis of Lan Chengyu corroded pipeline with associated defects显示文摘Traditional reliability evaluation method for corroded pipeline exists the problem of not considering the associated defects.We therefore propose a new calculation method considering the associated defects.In this paper,the traditional and new methods are respectively used to calculate and contrastively analyze the failure probability of corroded pipeline;we then perform the research of residual life prediction for the corroded pipeline,followed by the sensitivity calculation of all random evaluation parameters.And then the Monte Carlo method(MCS)is applied to verify the rationality of the new method.The research results show that:the method considering associated defect is more objective,and truly react corroded pipeline's dynamic reliability changes;obtain new method to predict residual life of corroded pipeline;corrosion depth,radial corrosion rate have a significant impact on reliability of corroded pipeline considering associated defects.The calculation results of the method are more accurate,more time-saving. | Qin Li Chunmei Sun Zhiqiang Huang Xiang Xiao Haiping Thang Shiying Zhao | 2015 | Petroleum2015，1，3： | 6 |

| 15 | Effect of dietary supplementation with sugar cane extract on meat quality and oxidative stability in finishing pigs显示文摘The aim of the present study was to investigate the effect of dietary supplementation with sugar cane extract(SCE) on meat quality and oxidative stability of Longissimus dorsi muscle in finishing pigs.Eighteen barrows(Duroc × Landrace × Jiaxing Black), with an average initial body weight of 62.1 ± 5.0 kg,were randomly allotted to 1 of 3 diets with 6 replicates per treatment for 42 days. The diets comprised a normal diet and the normal diets supplemented with 5 and 25 g/kg SCE. The results showed that SCE supplementation did not affect final body weight of finishing pigs. Dietary SCE supplementation significantly increased(P < 0.05) Longissimus dorsi muscle pH_(24 h),and tended to reduce(P < 0.1) and significantly decreased(P < 0.05) shear force, drip loss, myofiber cross sectional area and lactate dehydrogenase activity at 5 and 25 g/kg, respectively. Meanwhile, dietary SCE treatments significantly decreased(P < 0.05) malonaldehyde content and total superoxide dismutase activity in Longissimus dorsi muscle, and tended to reduce(P < 0.1) malonaldehyde content in serum. Altogether, these data indicate that SCE is an effective feed additive to improve pork meat quality, and the underlying mechanism may be partly due to the improved oxidative stability induced by dietary SCE supplementation. | Yangchun Xia Yansen Li Xiangxing Shen Massami Mizu Toma Furuta Chunmei Li | 2017 | Animal Nutrition2017，，3： | 5 |
| 16 | Dynamic Reliability Sensitivity of Cemented Carbide Cutting Tool显示文摘Influence of geometric and cutting parameters of cemented carbide cutting tool on reliability of cutting tool has become more and more mature,yet influence of its physical and material parameters on reliability is still blank.In view of this,cutting test and fatigue crack growth test of YT05 cemented carbide cutting tool are conducted to measure such data as the original crack size,growth size,times of impact loading,number and time of cutting tool in failure,and stress distribution of cutting tool is also obtained by simulating cutting process of tools.Mathematical models on dynamic reliability and dynamic reliability sensitivity of cutting tool are derived respectively by taking machining time and times of impact loading into account,thus change rules of dynamic reliability sensitivity to physical and material parameters can be obtained.Theoretical and experimental results show that sensitive degree on each parameter of tools increases gradually with the increase of machining time and times of impact loading,especially for parameters such as fracture toughness,shape parameter,and cutting stress.This proposed model solves such problems as how to determine the most sensitive parameter and influence degree of physical parameters and material parameters to reliability,which is sensitivity,and can provide theoretical foundation for improving reliability of cutting tool system. | WANG Xingang ZHANG Yimin LI He L Chunmei | 2014 | Chinese Journal of Mechanical Engineering2014，27，1： | 5 |
| 17 | Mandible exosomal ssc-mir-133b regulates tooth development in miniature swine via endogenous apoptosis显示文摘Signal transduction between different organs is crucial in the normal development of the human body. As an important medium for signal communication, exosomes can transfer important information, such as microRNAs(miRNAs), from donors to receptors.MiRNAs are known to fine-tune a variety of biological processes, including maxillofacial development; however, the underlying mechanism remains largely unknown. In the present study, transient apoptosis was found to be due to the expression of a miniature swine maxillofacial-specific miRNA, ssc-mir-133b. Upregulation of ssc-mir-133b resulted in robust apoptosis in primary dental mesenchymal cells in the maxillofacial region. Cell leukemia myeloid 1(Mcl-1) was verified as the functional target, which triggered further downstream activation of endogenous mitochondria-related apoptotic processes during tooth development.More importantly, mandible exosomes were responsible for the initial apoptosis signal. An animal study demonstrated that ectopic expression of ssc-mir-133 b resulted in failed tooth formation after 12 weeks of subcutaneous transplantation in nude mice. The tooth germ developed abnormally without the indispensable exosomal signals from the mandible. | Ye Li Xinxin Wang Jiali Ren Xiaoshan Wu Guoqing Li Zhipeng Fan Chunmei Zhang Ang Li Songlin Wang | 2018 | Bone Research2018，6，4： | 5 |
| 18 | Overview and countermeasures of cancer burden in China显示文摘Cancer is one of the leading causes of human death worldwide.Treatment of cancer exhausts significant medical resources,and the morbidity and mortality caused by cancer is a huge social burden.Cancer has therefore become a serious economic and social problem shared globally.As an increasingly prevalent disease in China,cancer is a huge challenge for the country’s healthcare system.Based on recent data published in the Journal of the National Cancer Center on cancer incidence and mortality in China in 2016,we analyzed the current trends in cancer incidence and changes in cancer mortality and survival rate in China.And also,we examined several key risk factors for cancer pathogenesis and discussed potential countermeasures for cancer prevention and treatment in China. | Yian Wang Qijia Yan Chunmei Fan Yongzhen Mo Yumin Wang Xiayu Li Qianjin Liao Can Guo Guiyuan Li Zhaoyang Zeng Wei Xiong He Huang | 2023 | Science China(Life Sciences)2023，66，11： | 5 |
| 19 | A novel selective autophagy receptor,CCDC50,delivers K63 polyubiquitination-activated RIG-I/MDA5 for degradation during viral infection显示文摘Autophagy is a con served process that delivers cytosolic substa nces to the lysosome for degradatio n,but its direct role in the regulation of antiviral inn ate immu nity remains poorly un derstood.Here,through high-throughput screeni ng,we discovered that CCDC50 functions as a previously unknown autophagy receptor that negatively regulates the type I interferon(IFN)signaling pathway initiated by RIG-I-like receptors(RLRs),the sensors for RNA viruses.The expression of CCDC50 is enhanced by viral infection,and CCDC50 specifically recognizes K63-polyubiquitinated RLRs,thus delivering the activated RIG-I/MDA5 for autophagic degradation.The associatio n of CCDC50 with phagophore membrane protei n LC3 is con firmed by crystal structure analysis.In contrast to other known autophagic cargo receptors that associate with either the LIR-docking site(LDS)or the UIMdocking site(UDS)of LC3,CCDC50 can bind to both LDS and UDS,representing a new type of cargo receptor.In mouse models with RNA virus infection,CCDC50 deficiency reduces the autophagic degradation of RIG-I/MDA5 and promotes type I IFN responses,resulting in enhaneed viral resistance and improved survival rates.These results reveal a new link between autophagy and antiviral innate immune resp on ses and provide additional in sights into the regulatory mecha nisms of RLR-mediated antiviral signaling. | Panpan Hou Kongxiang Yang Penghui Jia Lan Liu Yuxin Lin Zibo Li Jun Li Shuliang Chen Shuting Guo Ji'An Pan Junyu Wu Hong Peng Weijie Zeng Chunmei Li Yingfang Liu Deyin Guo | 2021 | Cell Research2021，31，1： | 5 |
| 20 | Pollen-based Holocene quantitative temperature reconstruction on the eastern Tibetan Plateau using a comprehensive method framework显示文摘Quantitative climate reconstruction on long timescales can provide important insights for understanding the climate variability and providing valuable data for simulations. Unfortunately, the credibility of some attempts was hampered by incomplete reconstruction procedures. We here establish a comprehensive framework resting on high-quality Chinese modern pollen database, including modern pollen data screening, calibration set selection, major climate factor analysis, appropriate model selection, strict statistical assessment of results and ecological interpretation. The application of this framework to three high-resolution pollen records from the eastern Tibetan Plateau allows accurate quantitative inferences of Holocene temperature changes, which is the major control of regional vegetation. The results show that the mean warmest month temperature(MTwa)during the early Holocene was ca. 10.4℃ and reached the highest value at 8.5–6 ka BP(ca. 11℃). The early and mid-Holocene(11–5 ka BP) warmth was followed by 1.2℃ temperature decrease, culminating in the coolest temperatures of the Holocene during the Neoglacial cooling. Superimposing on the general cooling trend, MTwareveals a significant 500-yr periodicity with varying intensities through time, showing that warm(cold) intervals are in phase with solar maxima(minima) periods. This spectral similarity indicates a possible connection of multi-century scale climate fluctuations with solar forcing. | Chen LIANG Yan ZHAO Feng QIN Zhuo ZHENG Xiayun XIAO Chunmei MA Huan LI Wenwei ZHAO | 2020 | Science China Earth Sciences2020，63，8： | 5 |
