2Experimental research on hydrophilic characteristics of natural soft rock at high stress state显示文摘In order to study features of rock–water interaction, a self-developed experimental system called Intelligent Testing System for Water Absorption in Deep Soft Rocks(ITSWADSR) was utilized to analyze the hydrophilic behaviors of natural soft rock at high stress state. Combining X-ray diffraction and mercury injection test, main influencing factors on hydrophilic characteristics were studied. According to the results, it could be concluded as the following:(1) the effective porosity, and the content of illite, illite/smectite formation(S = 5%) and kaolinite have positive correlation with the water absorption capacity of rock; meanwhile, the initial moisture content, fractal dimension of effective pores, illite/smectite formation(S = 30%) and chlorite present negative correlation;(2) among the positive factors, the ascending order is kaolinite, illite/smectite formation(S = 5%) and illite;(3) the descending order among the negative factors are chlorite, illite/smectite formation(S = 30%) and fractal dimension of the effective pores;(4) influence of effective porosity on the pressurized water absorbing capacity of rock is minimal, while it is maximal in the process of no pressurized water absorption.Guo Hongyun Lei Xiangyang Zhang Yumei Yang Guoxing Niu Zhang 2015International Journal of Mining Science and Technology2015,25,3:10
3Effects of recrystallization on the low cycle fatigue behavior of directionally solidified superalloy DZ40M显示文摘The effects of recrystallization on low cycle fatigue behavior were investigated on directionally solidified Co-base superalloy DZ40M. Opti-cal microscopy and SEM were used to examine the microstructure and fracture surface of the specimens. The mechanical testing results demonstrated that the low cycle fatigue property of DZ40M significantly decreased with the partial recrystallization. Fatigue cracks initiate near the carbides and the grain boundaries with slip-bands. Both the fatigue crack initiation and propagation can be accelerated with the oc-currences of recrystallized grain boundaries.ZHAO Yang WANG Lei LI Hongyun YU Teng LIU Yang 2008Rare Metals2008,27,4:8
4Development and validation of a nomogram for predicting the survival of patients with non-metastatic nasopharyngeal carcinoma after curative treatment显示文摘Background: The TNM staging system is far from perfect in predicting the survival of individual cancer patients because only the gross anatomy is considered. The survival rates of the patients who have the same TNM stage disease vary across a wide spectrum. This study aimed to develop a nomogram that incorporates other clinicopathologic factors for predicting the overall survival(OS) of non-metastatic nasopharyngeal carcinoma(NPC) patients after curative treatments.Methods: We retrospectively collected the clinical data of 1520 NPC patients who were diagnosed histologically between November 2000 and September 2003. The clinical data of a separate cohort of 464 patients who received intensity-modulated radiation therapy(IMRT) between 2001 and 2010 were also retrieved to examine the extensibility of the model. Cox regression analysis was used to identify the prognostic factors for building the nomogram. The predictive accuracy and discriminative ability were measured using the concordance index(c-index).Results: We identiied and incorporated 12 independent clinical factors into the nomogram. The calibration curves showed that the prediction of OS was in good agreement with the actual observation in the internal validation set and IMRT cohort. The c-index of the nomogram was statistically higher than that of the 7th edition TNM staging system for predicting the survival in both the primary cohort(0.69 vs. 0.62) and the IMRT cohort(0.67 vs. 0.63).Conclusion: We developed and validated a novel nomogram that outperformed the TNM staging system in predicting the OS of non-metastatic NPC patients who underwent curative therapy.Wenhua Liang Guanzhu Shen Yaxiong Zhang Gang Chen Xuan Wu Yang Li Anchuan Li Shiyang Kang Xi Yuan Xue Hou Peiyu Huang Yan Huang Hongyun Zhao Ying Tian Chong Zhao Li Zhang 2016Chinese Journal of Cancer2016,35,12:6
5China Nutrition and Health Surveys(1982−2017)显示文摘The status of nutrition and health among residents is one of the important indicators reflecting the developing level in a country or a region.China’s government initiated the first China National Nutrition Survey in 1959.The Second National Nutrition Survey and the Third National Nutrition Survey were then conducted in 1982 and 1992,respectively(1-2).The China National Nutrition and Health Survey(2002)combined the nutrition and chronic diseases survey and became the fourth survey(3).Dongmei Yu Liyun Zhao Jian Zhang Zhenyu Yang Lichen Yang Jian Huang Hongyun Fang Qiya Guo Xiaoli Xu Lahong Ju Gangqiang Ding 2021China CDC weekly2021,3,9:6
6The ACTIVE study protocol:apatinib or placebo plus gefitinib as first-line treatment for patients with EGFR-mutant advanced non-small cell lung cancer(CTONG1706)显示文摘Background:Gefitinib,as the first epidermal growth factor receptor tyrosine kinase inhibitors(EGFR-TKI)approved for the treatment of advanced non-small cell lung cancer(NSCLC),has been proved to significantly improve the progression-free survival(PFS)in the first-line setting but suffers from resistance 7-10 months after treatment initia-tion.Apatinib(YN968D1),a potent vascular endothelial growth factor receptor(VEGFR)2-TKI,specifically binds to VEGFR2 and leads to anti-angiogenetic and anti-neoplastic effect.Concurrent inhibition of VEGFR and EGFR path-ways represents a rational approach to improve treatment responses and delay the onset of treatment resistance in EGFR-mutant NSCLC.This ACTIVE study aims to assess the combination of apatinib and gefitinib as a new treatment approach for EGFR-mutant NSCLC as a first-line setting.Methods:This multicenter,randomized,double-blind,placebo-controlled phase III study(NCT02824458)has been designed to assess the efficacy and safety of apatinib or placebo combined with gefitinib as a first-line treatment for patients with EGFR-mutant advanced NSCLC.A total of 310 patients with EGFR-mutation(19del or 21L858R),pathological stage IIIB to IV non-squamous NSCLC were to be enrolled.The primary endpoint is investigator assessment of PFS,and the secondary endpoints include independent radiological central(IRC)-confirmed PFS,overall survival(OS),objective response rate(ORR),disease control rate(DCR),time to progressive disease(TTPD),duration of response(DoR),quality of life(QoL)and safety.The patients are randomized in a 1:1 ratio to receive gefitinib(250 mg,p.o.q.d.)plus apatinib(500 mg,p.o.q.d.)or gefitinib plus placebo,given until disease progression or intolerable adverse events.Exploratory biomarker analysis will be performed.This study is being conducted across China and comprises of 30 participating centers.Enrollment commenced in August 2017 and finished in December 2018,most of the patients are in the follow-up period.Anticipated outcomes and significance:The present study will be the first to evaluate the efficacy and safety profile of the combination of apatinib plus gefitinib as a first-line therapy for patients with EGFR-positive advanced non-squamous NSCLC.Importantly,this trial will provide comprehensive evidence on the treatment of EGFR-TKIs combined with antiangiogenic therapy.Zhonghan Zhang Fan Luo Yang Zhang Yuxiang Ma Shaodong Hong Yunpeng Yang Wenfeng Fang Yan Huang Li Zhang Hongyun Zhao 2019Cancer Communications2019,39,1:5
7Transcriptome analysis of the effect of pyrroloquinoline quinone disodium(PQQ·Na2) on reproductive performance in sows during gestation and lactation显示文摘Background: Pyrroloquinoline quinone(PQQ), which is a water soluble, thermo-stable triglyceride-quinone, is widely distributed in nature and characterized as a mammalian vitamin-like redox cofactor. The objective of this study was to investigate the effects of pyrroloquinoline quinone disodium(PQQ·Na2) on reproductive performance in sows.Results: Dietary supplementation with PQQ·Na2 significantly increased the total number of piglets born, the number of piglets born alive and the born alive litter weight. It also increased the antioxidant status in the placenta, plasma and milk. The concentration of NO was significantly increased in the plasma and placenta. RNA-seq analysis showed that462 unigenes were differentially expressed between the control(Con) treatment and PQQ treatment groups.Among these unigenes, 199 were upregulated, while 263 unigenes were downregulated. The assigned functions of the unigenes covered a broad range of GO categories. Reproduction(27, 7.03%) and the reproduction process(27, 7.03%) were assigned to the biological process category. By matching DEGs to the KEGG database, we identified 29 pathways.Conclusions: In conclusion, dietary supplementation with PQQ·Na2 in gestating and lactating sows had positive effects on their reproductive performance.Boru Zhang Chenxi Wang Wei Yang Hongyun Zhang Qingwei Meng Baoming Shi Anshan Shan 2019Journal of Animal Science and Biotechnology2019,10,4:5
8Genome-wide detection of additional fetal chromosomal abnormalities by cell-free DNA testing of 15,626 consecutive pregnant women显示文摘Cell-free DNA(cfDNA) testing for common fetal trisomies(T21, T18, T13) is highly effective. However, the usefulness of cfDNA testing in detecting other chromosomal abnormalities is unclear. We evaluated the performance of cfDNA testing for genome-wide abnormalities, and analyzed the incremental yield by reporting extra abnormalities. We performed genome-wide cfDNA testing in 15,626 consecutive pregnancies prospectively enrolled in this study. cfDNA testing results were reported and counseling was given depending on the presence of extra chromosomal abnormalities. cfDNA testing identified 190 cases(1.2%)of chromosomal abnormalities including 100 common trisomies and 90 additional abnormalities. By expanding the cfDNA reporting range to genome-wide abnormalities, the false positive rate increased to 0.39%(P<0.001) and positive predictive value(PPV) was reduced to 65.58%(P=0.42). However, the detection yield increased from 0.44% to 0.65%(P=0.014), and cfDNA testing detected 38.61%(39/101) additional abnormalities with no ultrasound and biochemical screening findings. cfDNA testing outperformed biochemical screening by showing 60 times higher true positive rate and fewer false negative results.Genome-wide cfDNA testing significantly increased the diagnostic yield by detecting extra abnormalities, especially those without diagnostic indications. Genome-wide cfDNA testing has fewer false positive and false negative results compared with biochemical screening.Hong Yao Ya Gao Jia Zhao Rong Zhang Huixin Xu Huamei Hu Yanmei Luo Yuying Yuan Meili Fu Hongyun Zhang Hui Jiang Wei Wang Huanming Yang Jian Wang Zhiqing Liang Fang Chen 2019Science China(Life Sciences)2019,62,2:4
9PTEN-L promotes type I interferon responses and antiviral immunity显示文摘Phosphatase and tensin homolog deleted on chromosome ten(PTEN)is a well-known tumor suppressor that acts as a dual-specificity phosphatase and is frequently mutated in human cancer.Our previous work has demonstrated that PTEN also plays a vital role in type I interferon responses and antiviral innate immunity.Recently,a translational variant of PTEN with a long N-terminal extension(PTEN-L)has been discovered that is secreted into the extracellular environment and enters recipient cells,where it exerts a phosphatase function antagonistic to PI3K/Akt signaling and tumorigenesis.In this study,we demonstrate that PTEN-L promotes type I interferon responses and antiviral innate immunity during viral infection in a phosphatase activity-dependent manner.Compared with canonical PTEN,PTEN-L also exerts its antiviral function when it is applied exogenously in protein form.This finding was confirmed in cell cultures and mouse infection models.Furthermore,PTEN-L enhances the responses of both type I interferon and proinflammatory cytokines,thus suggesting that PTEN-L might possess additional functions compared with those of PTEN.Thus,the antiviral function of PTEN-L may open an avenue for the use of PTEN-L in antiviral therapy,particularly in patients with PTEN-deficient tumors.Yuanyuan Cao Hongyun Wang Liu Yang Zhen Zhang Chenlin Li Xu Yuan Lang Bu Lang Chen Yu Chen Chun-Mei Li Deyin Guo 2018Cellular & Molecular Immunology2018,15,1:3
10Calibration of Mars Energetic Particle Analyzer (MEPA)显示文摘The first Mars exploration mission of China(Tianwen-1)is scheduled to be launched in 2020;a charged particle telescope,the Mars Energetic Particle Analyzer(MEPA),is carried as one of the payloads on the orbiter.The MEPA is designed to measure solar energetic particles(SEPs)and galactic cosmic rays(GCRs)in the near-Mars space and in the transfer orbit from Earth to Mars.Before the launch,the MEPA was calibrated in ground experiments with radioactive sources,electronic pulses,and accelerator beams.The calibration parameters,such as energy conversion constants,threshold values for the triggers,and particle identification criteria,were determined and have been stored for onboard use.The validity of the calibration parameters has been verified with radioactive sources and beams.The calibration results indicate that the MEPA can measure charged particles reliably,as designed,and that it can satisfy the requirements of the Tianwen-1 mission.ShuWen Tang Yi Wang HongYun Zhao Fang Fang Yi Qian YongJie Zhang HaiBo Yang CunHui Li Qiang Fu Jie Kong XiangYu Hu Hong Su ZhiYu Sun YuHong Yu BaoMing Zhang Yu Sun ZhiPeng Sun 2020Earth and Planetary Physics2020,4,4:2
11Preliminary investigation on cytotoxicity of fluorinated polymer nanoparticles显示文摘As well-known persistent organic pollutants(POPs), organofluorine pollutants such as perfluorooctane sulfonate(PFOS) have been proven to be bioaccumulated and harmful to health. However, toxicological assessment of organofluorinated nanoparticles, which have emerged as a novel tool for biomedical and industrial applications, is lacking, to the best of our knowledge. To assess the biological effects and health risk of fluorinated nanoparticles,trifluoroethyl aryl ether-based fluorinated poly(methyl methacrylate) nanoparticles(PTFEPMMA NPs) were synthesized with various fluorine contents(PTFE-PMMA-1 NPs 12.0 wt.%,PTFE-PMMA-2 NPs 6.1 wt.% and PTFE-PMMA-3 NPs 5.0 wt.%), and their cytotoxicity was investigated in this study. The in vitro experimental results indicated that the cytotoxicity of PTFE-PMMA NPs was mild, and was closely related to their fluorine(F) contents and Fcontaining side chains. Specifically, the cytotoxicity of PTFE-PMMA NPs decreased with increasing F content and F-containing side chains. After exposure to PTFE-PMMA NPs at a sublethal dose(50 μg/m L) for 24 hr, the phospholipid bilayer was damaged, accompanied by increasing permeability of the cell membrane. Meanwhile, the intracellular accumulation of reactive oxygen species(ROS) occurred, resulting in the increase of DNA damage, cell cycle arrest and cell death. Overall, the PTFE-PMMA NPs were found to be relatively safe compared with typical engineered nanomaterials(ENMs), such as silver nanoparticles and graphene oxide, for biomedical and industrial applications.Xue Wang Wenge Cheng Qiuyuan Yang Hongyun Niu Qian Liu Yun Liu Ming Gao Ming Xu An Xu Sijin Liu Xiaoyu Huang Yuguo Du 2018Journal of Environmental Sciences2018,30,7:2
12Combination of dynamic hollow fiber liquid-phase microextraction with HPLC analysis for the determination of UV filters in cosmetic products显示文摘A simple method based on hollow fiber liquid-phase microextraction (HF-LPME) followed by high performance liquid chro-matography (HPLC) analysis was successfully developed for the determination of UV filters in cosmetic products. A canular extractor was assembled by mounting a hollow fiber inside an external tube with a tee-connector. The organic solvent was immobilized into the fiber to form a liquid membrane as the acceptor phase. The sample was continuously injected into the extractor and the UV filters were extracted from the aqueous sample into organic acceptor phase. The main parameters affecting HF-LPME including extraction solvent, sample volume, sample flow rate, pH values and ionic strength were investigated. Toluene has been verified to be suitable as the acceptor phase. Under the optimized HF-LPME conditions, the enrichment factors of five UV filters varying from 24 to 57 were achieved. The limits of detection for the five UV filters were in the range of 1-100 μg L-1 .The relative standard deviations (RSDs) of HF-LPME and HPLC analysis were lower than 5.2%. The proposed method has been successfully applied to the analysis of the varied cosmetic products.YANG HongYun LI HaiFang Masahito Ito LIN Jin-Ming GUO GuangSheng DING MingYu 2011Science China Chemistry2011,54,10:2
13One-pot molten salt method for constructing CdS/C_(3)N_(4) nanojunctions with highly enhanced photocatalytic performance for hydrogen evolution reaction显示文摘The construction of heterojunction photocatalysts for efficiently utilizing solar energy has attracted considerable attention to solve the energy crisis and reduce environmental pollution.In this study,we use the energy released from an easily-occurred exothermic chemical reaction to serve as the drive force to trigger the formation of Cd S and C_(3)N_(4) nanocomposites which are successfully fabricated with cadmium nitrate and thiourea without addition of any solvents and protection of inert gas at initial temperature,a little higher than the melting point of thiourea.The as-prepared Cd S/C_(3)N_(4) materials exhibit high efficiency for photocatalytic hydrogen evolution reaction(HER)with the HER rate as high as 15,866μmol/(g·hr)under visible light irradiation(λ>420 nm),which is 89 and 9 times those of pristine C_(3)N_(4) and Cd S,respectively.Also,the apparent quantum efficiency(AQE)of Cd S/C_(3)N_(4)–1:2–200–2(Cd S/C_(3)N_(4)–1:2–200–2 means the ratio of Cd to S is 1:2 and the reaction temperature is set at 200℃ for two hours)reaches 3.25%atλ=420±15 nm.After irradiated for more than 24 hr,the HER efficiencies of Cd S/C_(3)N_(4) do not exhibit any attenuation.The DFT calculation suggests that the charge difference causes an internal electric field from C_(3)N_(4) pointing to Cd S,which can more effectively promote the transfer of photogenerated electrons from Cd S to C_(3)N_(4).Therefore,most HER should occur on C_(3)N_(4) surface where photogenerated electrons accumulate,which largely protects Cd S from photo-corrosion.Weijia Zhao Hongyun Niu Yongliang Yang Hongzhou Lv Jungang Lv Yaqi Cai 2022Journal of Environmental Sciences2022,34,2:2
