1Time range of Mesozoic tectonic regime inversion in eastern North China Block显示文摘An important tectonic inversion took place in eastern North China Block(NCB) during Mesozoic, which caused a great lithosphere thinning, reconstruction of basin-range series, powerful interaction between mantle and crust, a vast granitic intrusion and volcanism, and large-scale metallogenic explosion. The time range of the Mesozoic tectonic regime inversion in the eastern North China Block is one of the key issues to understand mechanism of tectonic regime inversion. Our updated results for recognizing the time range are mainly obtained from the following aspects: structural analyses along northern and southern margins of the NCB and within the NCB for revealing tectonic inversion from compression to extension and structural striking from ~EW to NNE; geothermic analyses of the eastern sedimental basins for a great change of thermal history and regime; basin analysis for basin inversion from compression to extension and basin migration from ~EW to NNE; petrological and geochemical studies of volcanic rocks and lowermost crust xenoliths for recognizing peak period of mantle upwelling and intense interaction between mantle and crust, and main metallogenic epoch. All the studies of the above give the same time range from~150-140 Ma to ~110-100Ma, peaking at ~120 Ma.ZHAI Mingguo ZHU Rixiang LIU Jianming MENG Qingren HOU Quanlin HU Shengbiao LIU Wei LI Zhong ZHANG Hongfu ZHANG Huafeng 2004Science China Earth Sciences2004,47,2:89
2Clinical and biochemical indexes from 2019-nCoV infected patients linked to viral loads and lung injury显示文摘The outbreak of the 2019-nCoV infection began in December 2019 in Wuhan,Hubei province,and rapidly spread to many provinces in China as well as other countries.Here we report the epidemiological,clinical,laboratory,and radiological characteristics,as well as potential biomarkers for predicting disease severity in 2019-nCoV-infected patients in Shenzhen,China.All 12 cases of the 2019-nCoV-infected patients developed pneumonia and half of them developed acute respiratory distress syndrome (ARDS).The most common laboratory abnormalities were hypoalbuminemia,lymphopenia,decreased percentage of lymphocytes (LYM) and neutrophils (NEU),elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH),and decreased CD8 count.The viral load of 2019-nCoV detected from patient respiratory tracts was positively linked to lung disease severity.ALB,LYM,LYM (%),LDH,NEU (%),and CRP were highly correlated to the acute lung injury.Age,viral load,lung injury score,and blood biochemistry indexes,albumin (ALB),CRP,LDH,LYM (%),LYM,and NEU (%),may be predictors of disease severity.Moreover,the Angiotensin Ⅱlevel in the plasma sample from 2019-nCoV infected patients was markedly elevated and linearly associated to viral load and lung injury.Our results suggest a number of potential diagnosis biomarkers and angiotensin receptor blocker (ARB) drugs for potential repurposing treatment of 2019-nCoV infection.Yingxia Liu Yang Yang Cong Zhang Fengming Huang Fuxiang Wang Jing Yuan Zhaoqin Wang Jinxiu Li Jianming Li Cheng Feng Zheng Zhang Lifei Wang Ling Peng Li Chen Yuhao Qin Dandan Zhao Shuguang Tan Lu Yin Jun Xu Congzhao Zhou Chengyu Jiang Lei Liu 2020Science China(Life Sciences)2020,63,3:157
3Why Lake Taihu continues to be plagued with cyanobacterial blooms through 10 years(2007–2017) efforts显示文摘With the expansion of urban, industry, and agriculture after World War II, eutrophication firstly emerged as a major water quality threat in small water bodies [1]. As the increasing magnitudes and scales of nutrient pollution and habitat alteration, many of the world's large lakes exhibit symptoms of eutrophication, e.g., toxic cyanobacterial blooms, deoxygenation, and habitat loss.Boqiang Qin Hans W.Paerl Justin D.Brookes Jianguo Liu Erik Jeppesen Guangwei Zhu Yunlin Zhang Hai Xu Kun Shi Jianming Deng 2019Science Bulletin2019,64,6:50
4Efficacy 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 2021Cancer Communications2021,41,11:29

6Relations between oxygen stable isotopic ratios in precipitation and relevant meteorological factors in southwest China显示文摘The correlations of isotopic ratios in precipitation with temperature, air pressure and humidity at dif- ferent altitudes, in southwest China, are analyzed. There appear marked negative correlations for the δ 18O in precipitation with precipitation amount, vapor pressure and atmospheric precipitable water (PW) at Mengzi, Simao and Tengchong stations on synoptic timescale; the marked negative correlations between the δ 18O in precipitation and the diurnal mean temperature at 400 hPa, 500 hPa, 700 hPa and 850 hPa are different from the temperature effect in middle-high-latitude inland. Moreover, the notable positive correlation between the δ 18O in precipitation and the dew-point deficit △Td at different altitudes is found at the three stations. On annual timescale, the annual precipitation amount weighted mean δ 18O display the negative correlations not only with annual precipitation but also with annual mean temperature at 500 hPa. It can be deduced that, in the years with abnormally strong summer monsoon, more warm and wet air from low-latitude oceans is transported northward along the vapor channel located in southwest China and generates abnormally strong rainfall on the way. Meanwhile, the ab- normally strong condensation process will release more condensed latent heat into atmosphere, and lead to the rise of atmospheric temperature during rainfall, but decline of the δ 18O in precipitation. On the contrary, in the years with abnormally weak summer monsoon, the abnormally weak condensation process will release less condensed latent heat into atmosphere, and lead to the decline of atmos- pheric temperature during rainfall, but increase of the δ 18O in precipitation.ZHANG XinPing LIU JingMiao SUN WeiZheng HUANG YiMin ZHANG JianMing 2007Science China Earth Sciences2007,50,4:17
7Application of next-generation sequencing technology to precision medicine in cancer: joint consensus of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology显示文摘Next-generation sequencing(NGS) technology is capable of sequencing millions or billions of DNA molecules simultaneously.Therefore, it represents a promising tool for the analysis of molecular targets for the initial diagnosis of disease, monitoring of disease progression, and identifying the mechanism of drug resistance. On behalf of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology(CSCO) and the China Actionable Genome Consortium(CAGC), the present expert group hereby proposes advisory guidelines on clinical applications of NGS technology for the analysis of cancer driver genes for precision cancer therapy. This group comprises an assembly of laboratory cancer geneticists, clinical oncologists, bioinformaticians,pathologists, and other professionals. After multiple rounds of discussions and revisions, the expert group has reached a preliminary consensus on the need of NGS in clinical diagnosis, its regulation, and compliance standards in clinical sample collection. Moreover, it has prepared NGS criteria, the sequencing standard operation procedure(SOP), data analysis, report, and NGS platform certification and validation.Xuchao Zhang Zhiyong Liang Shengyue Wang Shun Lu Yong Song Ying Cheng Jianming Ying Weiping Liu Yingyong Hou Yangqiu Li Yi Liu Jun Hou Xiufeng Liu Jianyong Shao Yanhong Tai Zheng Wang Li Fu Hui Li Xiaojun Zhou Hua Bai Mengzhao Wang You Lu Jinji Yang Wenzhao Zhong Qing Zhou Xuening Yang Jie Wang Cheng Huang Xiaoqing Liu Xiaoyan Zhou Shirong Zhang Hongxia Tian Yu Chen Ruibao Ren Ning Liao Chunyan Wu Zhongzheng Zhu Hongming Pan Yanhong Gu Liwei Wang Yunpeng Liu Suzhan Zhang Tianshu Liu Gong Chen Zhimin Shao Binghe Xu Qingyuan Zhang Ruihua Xu Lin Shen Yilong Wu 2019Cancer Biology & Medicine2019,16,1:14

10An H3K27me3 demethylase-HSFA2 regulatory loop orchestrates transgenerational thermomemory in Arabidopsis显示文摘Global warming has profound effects on plant growth and fitness.Plants have evolved sophisticated epigenetic machinery to respond quickly to heat,and exhibit transgenerational memory of the heat-induced release of post-transtriptional gene silencing(PTGS).However,how thermomemory is transmitted to progeny and the physiological relevance are elusive.Here we show that heat-induced HEAT SHOCK TRANSCRIPTION FACTOR A2(HSFA2)directly activates the H3K27me3 demethylase RELATIVE OF EARLY FLOWERING 6(REF6),which in turn derepresses HSFA2.REF6 and HSFA2 establish a heritable feedback loop,and activate an E3 ubiquitin ligase,SUPPRESSOR OF GENE SILENCING 3(SGS3)-INTERACTING PROTEIN 1(SGIP1).SGIP1-mediated SGS3 degradation leads to inhibited biosynthesis of trans-acting siRNA(tasiRNA).The REF&HSFA2 loop and reduced tasiRNA converge to release HEAT-INDUCED TAS1 TARGET 5(HTT5),which drives early flowering but attenuates immunity.Thus,heat induces transmitted phe no types via a coordi nated epigenetic network involvi ng histone demethylases,tran scriptio n factors,and tasiRNAs,ensuring reproductive success and transgenerational stress adaptation.Junzhong Liu Lili Feng Xueting Gu Xian Deng Qi Qiu Qun Li Yingying Zhang Muyang Wang Yiwen Deng Ertao Wang Yuke He Isabel Baurle Jianming Li Xiaofeng Cao Zuhua He 2019Cell Research2019,29,5:10
11Geochemical research on C-O and Sr-Nd isotopes of mantle-derived rocks from Shandong Province, China显示文摘This paper presents systematic studies on the C-O and Sr-Nd isotopic compositions for Cretaceous Badou carbonatites, Fangcheng basalts, and Jiaodong lamprophyres and Paleozoic Mengyin kimberlites in Shandong Province, China. Paleozoic kimberlites have normal and uniform C-O isotopic compositions with δ13C and δ18O in the range of -4.8‰--7.6‰ and +9.9‰-+13.2‰, respectively. However, Cretaceous three different types of mantle-derived rocks have quite different C-O isotopic compositions, indicating that the mantle sources are probably partially contaminated with organic carbon-bearing crustal materials. These Cretaceous rocks show uniform and EMII-like Sr-Nd isotopic compositions and also indicate that the mantle sources were affected by recycled crustal materials. Comparative studies of C-O and Sr-Nd isotopes reveal that the lithospheric mantle beneath the eastern North China Craton had different isotope characteristics in the Paleozoic, the early Cretaceous, and the Tertiary time. This demonstrates that the lithospheric mantle beneath the region underwent at least twice reconstructions since the Paleozoic. Available data imply that the first reconstruction mainly happened during the Triassic-Jurassic time with gradual changes and the second in the Cretaceous with abrupt changes. Results also show that the early Cretaceous (especially at 120-130 Ma) was perhaps the key period leading to the dramatic change of the Mesozoic geodynamics on the eastern North China Craton.LIU Jianming, ZHANG Hongfu, SUN Jinggui & YE Jie1.

15Geology and Geochemistry of the Bianbianshan Au-Ag-Cu-Pb-Zn Deposit, Southern Da Hinggan Mountains, Northeastern China显示文摘The Bianbianshan deposit, the unique gold-polymetal (Au-Ag-Cu-Pb-Zn) veined deposit of the polymetal metallogenic belt of the southern segment of Da Hinggan Mountains mineral province, is located at the southern part of the Hercynian fold belt of the south segment of Da Hinggan Mountains mineral province, NE China. Ores at the Bianbianshan deposit occur within Cretaceous andesite and rhyolite in the form of gold-bearing quartz veins and veinlet groups containing native gold, electrum, pyrite, chalcopyrite, galena and sphalerite. The deposit is hosted by structurally controlled faults associated with intense hydrothermal alteration. The typical alteration assemblage is sericite + chlorite + calcite + quartz, with an inner pyrite-sericite-quartz zone and an outer seicite - chlorite - calcite-epidote zone between orebodies and wall rocks. δ34 S values of 17 sulfides from ores changing from -1.67 to +0.49‰ with average of -0.49‰, are similar to δ34 S values of magmatic or igneous sulfide sulfur. 206Pb/204Pb, 207Pb/204Pb and 208Pb/ 204Pb data of sulfide from ores range within 17.66-17.75, 15.50-15.60, and 37.64-38.00, respectively. These sulfur and lead isotope compositions imply that ore-forming materials might mainly originate from deep sources. H and O isotope study of quartz from ore-bearing veins indicate a mixed source of deep-seated magmatic water and shallower meteoric water. The ore formations resulted from a combination of hydrothermal fluid mixing and a structural setting favoring gold-polymetal deposition. Fluid mixing was possibly the key factor resulting in Au-Ag-Cu-Pb-Zn deposition in the deposit. The metallogenesis of the Bianbianshan deposit may have a relationship with the Cretaceous volcanic-subvolcanic magmatic activity, and formed during the late stage of the crust thinning of North China.ZENG Qingdong LIU Jianming LIU Hongtao 2012Acta Geologica Sinica(English Edition)2012,86,3:6
16High manure load reduces bacterial diversity and network complexity in a paddy soil under crop rotations显示文摘Long-term application of chemical fertilizers causes soil degradation and nitrogen(N)loss,but these effects could be alleviated by organic fertilizers.In addition,crop rotation is a feasible practice to increase soil fertility,soil quality and crop yields comparing with monocultural cropping patterns.However,questions remain concerning how the soil microbiome responds to different manure application rates under crop rotations.Here,we collected soil samples from a rice-rape system to investigate the response of the soil microbiome to nine years of pig manure application at different rates(CK:0 kg ha^(-1),M1:1930 kg ha^(-1),M2:3860 kg ha^(-1) and M3:5790 kg ha^(-1)).Our results revealed that the bacterialα-diversity(Chao1 and Shannon index)in the rape season increased first and then decreased with increasing manure application rates,and a high manure load tended to decrease the bacterialα-diversity in the rice season.Long-term manure application enriched some copiotrophic bacteria,such as Proteobacteria and Actinobacteria,while it decreased the relative abundance of Nitrospirae.Redundancy analysis(RDA)and the Mantel test indicated that soil pH,TC,TN,AP,C/P and N/P ratios were the main factors influencing bacterial communities.Moreover,network analysis showed that a low manure application rate shaped a complexly connected and stable bacterial community,while higher manure application rate decreased the stability of the bacterial network.These findings improve our understanding of bacterial responses to longterm manure application under crop rotations and their relationships with soil factors,especially in the context of increasing fertilizer inputs.Haiyang Liu Xing Huang Wenfeng Tan Hongjie Di Jianming Xu Yong Li 2020Soil Ecology Letters2020,2,2:6
17Pertuzumab in combination with trastuzumab and chemotherapy for Chinese patients with HER2-positive metastatic gastric or gastroesophageal junction cancer:a subpopulation analysis of the JACOB trial显示文摘Background:The JACOB trial(NCT01774786)was a double-blinded,placebo-controlled,randomized,multicenter,international,phase III trial evaluating the efficacy and safety of adding pertuzumab to trastuzumab and chemo-therapy in first-line treatment of human epidermal growth factor receptor 2(HER2)-positive metastatic gastric cancer/gastroesophageal junction cancer(GEJC).The aim of this analysis was to investigate efficacy and safety outcomes in the Chinese subpopulation from the JACOB trial.Methods:This post hoc subpopulation analysis included all patients recruited in China's Mainland(n=163;20.9%)between June 2013 and January 2016.The patients were randomly assigned in a 1:1 ratio to receive pertuzumab plus trastuzumab and chemotherapy(pertuzumab group;n=82)or placebo plus trastuzumab and chemotherapy(con-trol group;n=81).Intravenous pertuzumab(840 mg)and trastuzumab(8 mg/kg loading and 6 mg/kg maintenance doses)were given every 3 weeks until disease progression or unacceptable toxicity.Chemotherapy was given as per standard regimens/doses of capecitabine or 5-fluorouracil plus cisplatin.The primary endpoint was overall survival(OS);secondary efficacy endpoints included progression-free survival(PFS),and overall objective response rate(ORR).Results:The median OS was 18.7 months in the pertuzumab group and 16.1 months in the control group(hazard ratio[HR]0.75;95%confidence interval[CI]0.49 to 1.14).The median PFS was 10.5 and 8.6 months in the pertuzumab and control groups,respectively(HR 0.85;95%CI 0.60 to 1.21),and the median ORRs were 68.9%and 55.7%,respectively.The treatment effect in this Chinese subpopulation showed consistency with that in the global ITT population with numerically lower HR for OS and PFS compared with the control group.The safety profiles of the pertuzumab and control groups in this Chinese subpopulation analysis were generally comparable.The most common grade 3-5adverse events were neutropenia,anemia,and leukopenia.However,due to the nature of being a post hoc subgroup analysis,the results presented here are descriptive only and need to be interpreted with caution.Conclusions:OS and PFS were numerically improved by adding pertuzumab to trastuzumab and chemotherapy as first-line treatment in Chinese HER2-positive gastric cancer/GEJC patients,and this regimen demonstrated an acceptable safety profile.Tianshu Liu Yanru Qin Jin Li Ruihua Xu Jianming Xu Shujun Yang Shukui Qin Yuxian Bai Changping Wu Yixiang Mao Haiyan Wu Yilin Ge Lin Shen 2019Cancer Communications2019,39,1:6
18Elevated plasma levels of selective cytokines in COVID-19 patients reflect viral load and lung injury显示文摘A recent outbreak of pneumonia in Wuhan,China was found to be caused by a 2019 novel coronavirus(2019-nCoV or SARS-CoV-2 or HCoV-19).We previously reported the clinical features of 12 patients with2019-n Co V infections in Shenzhen,China.To further understand the pathogenesis of COVID-19 and find better ways to monitor and treat the disease caused by 2019-n Co V,we measured the levels of 48 cytokines in the blood plasma of those 12 COVID-19 patients.Thirty-eight out of the 48 measured cytokines in the plasma of 2019-n Co V-infected patients were significantly elevated compared to healthy individuals.Seventeen cytokines were linked to 2019-nCoV loads.Fifteen cytokines,namely M-CSF,IL-10,IFN-α2,IL-17,IL-4,IP-10,IL-7,IL-1 ra,G-CSF,IL-12,IFN-γ,IL-1α,IL-2,HGF and PDGF-BB,were strongly associated with the lung-injury Murray score and could be used to predict the disease severity of2019-n Co V infections by calculating the area under the curve of the receiver-operating characteristics.Our results suggest that 2019-nCoV infections trigger extensive changes in a wide array of cytokines,some of which could be potential biomarkers of disease severity of 2019-n Co V infections.These findings will likely improve our understanding of the immunopathologic mechanisms of this emerging disease.Our results also suggest that modulators of cytokine responses may play a therapeutic role in combating the disease once the functions of these elevated cytokines have been characterized.Yingxia Liu Cong Zhang Fengming Huang Yang Yang Fuxiang Wang Jing Yuan Zheng Zhang Yuhao Qin Xiaoyun Li Dandan Zhao Shunwang Li Shuguang Tan Zhaoqin Wang Jinxiu Li Chenguang Shen Jianming Li Ling Peng Weibo Wu Mengli Cao Li Xing Zhixiang Xu Li Chen Congzhao Zhou William J Liu Lei Liu Chengyu Jiang 2020National Science Review2020,7,6:6
19Cell-free plasma hypermethylated CASZ1, CDH13 and ING2 are promising biomarkers of esophageal cancer显示文摘Identifying sensitive and specific biomarkers for early detection of cancer is immensely imperative for early diagnosis and treatment and better clinical outcome of cancer patients. This study aimed to construct a specific DNA methylation pattern of cancer suppressor genes and explore the feasibility of applying cell-free DNA based methylation as a biomarker for early diagnosis of esophageal squamous cell carcinoma(ESCC). We recruited early stage ESCC patients from Yangzhong County, China. The Illumina Infinium 450 K Methylation BeadChip was used to construct a genome-wide DNA methylation profile. Then, differentiated genes were selected for the validation study using the Sequenom MassARRAY platform. The frequency of methylation was compared between cancer tissues, matched cell-free DNAs and normal controls. The specific methylation profiles were constructed, and the sensitivity and specificity were calculated. Seven CG sites in three genes CASZ1, CDH13 and ING2 were significantly hypermethylated in ESCC as compared with normal controls. A significant correlation was found between the methylation of DNA extracted from cancer tissues and matched plasma cell-free DNA, either for individual CG site or for cumulative methylation analysis. The sensitivity and specificity reached 100% at an appropriate cut-point using these specific methylation biomarkers. This study revealed that aberrant DNA methylation is a promising biomarker for molecular diagnosis of esophageal cancer. Hypermethylation of CASZ1,CDH13 and ING2 detected in plasma cell-free DNA can be applied as a potential noninvasive biomarker for diagnosis of esophageal cancer.Huanqiang Wang Congying Yang Siyuan Wang Tian Wang Jingling Han Kai Wei Fucun Liu Jida Xu Xianzhen Peng Jianming Wang 2018The Journal of Biomedical Research2018,32,6:6
20Robust YAG:Ce single crystal for ultra-high efficiency laser lighting显示文摘At present,solid-state laser-driven lighting fabricated with blue laser diode(LD)and phosphor has been greatly developed in high-power lighting applications.The major obstacle is the luminescence saturation threshold of the fluorescence conversion material(YAG:Ce).In this work,we successfully prepared a series of high-quality and robust YAG:Ce single crystals.With high quantum efficiency(QE=92%),regular crystal structure and high thermal conductivity,the single-crystal has excellent ability to deal with high radiation flux and thermal accumulation generated by high power.Matching the single-crystal with the laser,the luminous efficiency up to 274 lm/W and saturation threshold of 12 W/mm^(2) were obtained.In addition,the influence of Ce doping concentration and sample processing conditions on the indicators in laser-driven white lighting was systematically studied.The results are of great significance and are believed to promote the development of solid-state laser-driven lighting.Yaqian Zhang Jianming Liu Yujie Zhang Haisheng Yang Yanxia Yu Qingyun He Xiaojuan Liang Yongfu Liu Weidong Xiang 2022Journal of Rare Earths2022,40,5:5
