| 1 | Genome analysis of Taraxacum kok-saghyz Rodin provides new insights into rubber biosynthesis显示文摘The Russian dandelion Taraxacum kok-saghyz Rodin(TKS), a member of the Composite family and a potential alternative source of natural rubber(NR) and inulin, is an ideal model system for studying rubber biosynthesis. Here we present the draft genome of TKS, the first assembled NR-producing weed plant. The draft TKS genome assembly has a length of 1.29 Gb, containing 46 731 predicted protein-coding genes and68.56% repeats, in which the LTR-RT elements predominantly contribute to the genome enlargement. We analyzed the heterozygous regions/genes, suggesting its possible involvement in inbreeding depression.Through comparative studies between rubber-producing and non-rubber-producing plants, we found that enzymes of the mevalonate(MVA) pathway and rubber elongation might be critical for rubber biosynthesis, and several key isoforms have been isolated and shown to be predominantly expressed in the latex, indicating their crucial functions in rubber biosynthesis. Moreover, for two important families in rubber elongation, the CPT/CPTL and REF/SRPP families, diverse evolutionary tracks have been revealed. These results provide valuable resources and new insights into the mechanism of NR biosynthesis,and facilitate the development of alternative NR-producing crops. | Tao Lin Xia Xu Jue Ruan Shizhong Liu Shigang Wu Xiujuan Shao Xiaobo Wang Lin Gan Bi Qin Yushuang Yang Zhukuan Cheng Suhua Yang Zhonghua Zhang Guosheng Xiong Sanwen Huang Hong Yu Jiayang Li | 2018 | National Science Review2018，5，1： | 22 |
| 2 | Downstaging and resection of hepatocellular carcinoma in patients with extrahepatic metastases after stereotactic therapy显示文摘Background:A combination of tyrosine kinase inhibitors(TKIs)and anti-PD-1 antibodies with local regional therapy has elicited yield substantial clinical benefits in patients who have hepatocellular carcinoma(HCC)with extrahepatic metastases.Using this treatment strategy to convert HCC patients with extrahepatic metastases from unresectable to resectable has not yet been reported.Methods:Consecutive hepatocellular carcinoma patients with extrahepatic metastases who received first-line therapy with a combination of TKIs and anti-PD-1 antibodies and at least one local regional therapy were analysed.Results:Nine patients with localized disease who received first-line systemic therapy were enrolled.At baseline,all of them had oligometastatic disease,namely,Barcelona Clinic Liver Cancer stage C(or Chinese Liver Cancer stage IIIB).The most common treatment administered was lenvatinib plus anti-PD-1 antibody and transarterial chemoembolization,and the median time span from systemic therapy to surgery was 3.2(IQR,2.8-6.2)months.Three patients achieved a pathological complete response.Six patients underwent laparoscopic surgery,and the other 3 patients underwent open surgery.After a median follow-up of 10.2(IQR,8.6-20.0)months,7 patients survived without disease recurrence,and 2 experienced tumour recurrence.All patients had any-grade AEs,and 55.6%of the patients experienced grade 3 AEs.Fatigue was the most common AE,followed by elevated aminotransferase levels and hypertension.Conclusions:Stereotactic therapy is a feasible conversion therapy for HCC patients with extrahepatic metastases to become resectable.This is the first study to analyse therapeutic outcomes of patients receiving these therapies for HCC with extrahepatic metastases. | Xiaobo Yang Haifeng Xu Bangyou Zuo Xu Yang Jin Bian Junyu Long Dongxu Wang Junwei Zhang Cong Ning Yanyu Wang Ziyu Xun Yunchao Wang Xin Lu Yilei Mao Xinting Sang Haitao Zhao | 2021 | Hepatobiliary Surgery and Nutrition2021，10，4： | 17 |
| 3 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |
| 4 | Dietary seaweed-derived polysaccharides improve growth performance of weaned pigs through maintaining intestinal barrier function and modulating gut microbial populations显示文摘Background:Seaweed-derived polysaccharides(SDP)represent an attractive source of prebiotic nutraceuticals for the food and animal husbandry industry.However,the mechanism by which SDP from Enteromorpha mediates pig growth are not fully understood.This study aimed to investigate how SDP supplementation influences the growth performance and intestinal health in weaned pigs.Results:In Exp.1,240 weaned pigs were randomly assigned to four dietary treatments and fed with a basal diet or a basal diet containing 200,400 or 800 mg/kg SDP,respectively,in a 21-day trial.Pigs on the 400 or 800 mg/kg SDP-supplemented group had greater ADG and lower F/G ratio than those on the control group(P<0.05).In Exp.2,20 male weaned pigs were randomly assigned to two treatments and fed with a basal diet(CON group)or a basal diet supplemented with 400 mg/kg SDP(the optimum does from Exp.1),in a 21-day trial.Pigs fed the SDP diet had greater ADG,the concentrations of serum IL-6 and TNF-αand the activities of glutathione peroxidase,superoxide dismutase and catalase(P<0.05),and lower F/G,diarrhea rate,as well as serum D-lactate concentrations and diamine oxidase activity(P<0.05).Moreover,dietary SDP supplementation enhanced secretory immunoglobulin A content,villus height and villous height:crypt depth ratio in small intestine,as well as the lactase and maltase activities in jejunum mucosa(P<0.05).SDP supplementation elevated the mRNA levels of inflammatory responserelated genes(IL-6,TNF-α,TLR4,TLR6 and MyD88),and the mRNA and protein levels of ZO-1,claudin-1 and occludin in jejunum mucosa(P<0.05).Importantly,SDP not only increased the Lactobacillus population but also reduced the Escherichia coli population in cecum(P<0.05).Furthermore,SDP increased acetic acid and butyric acid concentrations in cecum(P<0.05).Conclusions:These results not only suggest a beneficial effect of SDP on growth performance and intestinal barrier functions,but also offer potential mechanisms behind SDP-facilitated intestinal health in weaned pigs. | Tiande Zou Jin Yang Xiaobo Guo Qin He Zirui Wang Jinming You | 2021 | Journal of Animal Science and Biotechnology2021，12，3： | 10 |
| 5 | Plasma metabolomic and lipidomic alterations associated with COVID-19显示文摘The pandemic of the coronavirus disease 2019(COVID-19)has become a global public health crisis.The symptoms of COVID-19 range from mild to severe,but the physiological changes associated with COVID-19 are barely understood.In this study,we performed targeted metabolomic and lipidomic analyses of plasma from a cohort of patients with COVID-19 who had experienced different symptoms.We found that metabolite and lipid alterations exhibit apparent correlation with the course of disease in these patients,indicating that the development of COVID-19 affected their whole-body metabolism.In particular,malic acid of the TCA cycle and carbamoyl phosphate of the urea cycle result in altered energy metabolism and hepatic dysfunction,respectively.It should be noted that carbamoyl phosphate is profoundly down-regulated in patients who died compared with patients with mild symptoms.And,more importantly,guanosine monophosphate(GMP),which is mediated not only by GMP synthase but also by CD39 and CD73,is significantly changed between healthy subjects and patients with COVID-19,as well as between the mild and fatal cases.In addition,dyslipidemia was observed in patients with COVID-19.Overall,the disturbed metabolic patterns have been found to align with the progress and severity of COVID-19.This work provides valuable knowledge about plasma biomarkers associated with COVID-19 and potential therapeutic targets,as well as an important resource for further studies of the pathogenesis of COVID-19. | Di Wu Ting Shu Xiaobo Yang Jian-Xin Song Mingliang Zhang Chengye Yao Wen Liu Muhan Huang Yuan Yu Qingyu Yang Tingju Zhu Jiqian Xu Jingfang Mu Yaxin Wang Hong Wang Tang Tang Yujie Ren Yongran Wu Shu-Hai Lin Yang Qiu Ding-Yu Zhang You Shang Xi Zhou | 2020 | National Science Review2020，7，7： | 9 |
| 6 | Effect of SiC particle addition on microstructure of Mg_2Si/Al composite显示文摘In the present study, by adding SiC particles into Al-Si-Mg melt, Mg2Si and SiC particles hybrid reinforced Al matrix composites were fabricated through the Mg2Si in situ synthesis in melt combined with the SiC ex situ stir casting. The as-cast microstructure containing primary Mg2Si and SiC particles that distribute homogenously in Al matrix was successfully achieved. The effects of SiC particle addition on the microstructure of Mg2Si/Al composites were investigated by using scanning electron microscopy(SEM) and XRD. The results show that, with increasing the fraction of the SiC particles from 5wt.% to 10wt.%, the morphologies of the primary Mg2Si particulates in the prepared samples remain polygonal, but the size of the primary phase decreases slightly. However, when the SiC particle addition reaches 15wt.%, the morphologies of the primary Mg2Si particulates change partially from polygonal to quadrangular with a decrease in size from 50 μm to 30 μm. The size of primary Al dendrites decreases with increasing fraction of the SiC particles from 0wt.% to 15wt.%. The morphology of the eutectic Mg2Si phase changes from a fi ber-form to a short fi ber-form and/or a dot-like shape with increasing fraction of the SiC particles. Furthermore, no signifi cant change in dendrite arm spacing(DAS) was observed in the presence of SiC particles. | Zhao Yuguang Liu Xiaobo Yang Yuanyuan Bian Tianjun | 2014 | China Foundry2014，11，2： | 8 |
| 7 | Effects of ecological factors on secondary metabolites and inorganic elements of Scutellaria baicalensis and analysis of geoherblism显示文摘This study analyzed the effects of ecological factors on secondary metabolites of Scutellaria baicalensis using two sources:92individual roots of S.baicalensis from all over China,and secondary metabolites,medicinal materials and inorganic element contents obtained from the testing of 92 S.baicalensis rhizosphere soil samples.The study used environmental data from the Genuine Medicinal Material Spatial Analysis Database.Most of the chemical constituents of S.baicalensis were negatively correlated to latitude and positively correlated to temperature;generally,the contents of 21 chemical constituents were higher at low latitudes than that at high latitudes.By gradual regression analysis,it was found that the content of baicalin in S.baicalensis was negatively correlated to latitude and generally the content of inorganic elements in soil was excessively high(excluding Mg and Ca),which has a negative effect on the accumulation of chemical constituents in S.baicalensis.Based on the cluster analysis of 21 constituents,S.baicalensis from different places of origin was divided into two groups,and S.baicalensis was not genuine only in a specific small region.Within the zone from Chifeng,Inner Mongolia to Taibai,Shaanxi is suitable for accumulation of secondary metabolites of S.baicalensis and such a zone represents a suitable distribution and potential genuine producing area. | GUO LanPing WANG Sheng ZHANG Ji YANG Guang ZHAO ManXi MA WeiFeng ZHANG XiaoBo LI Xuan HAN BangXing CHEN NaiFu HUANG LuQi | 2013 | Science China(Life Sciences)2013，56，11： | 7 |
| 8 | Sirtuin 5:a review of structure,known inhibitors and clues for developing new inhibitors显示文摘Sirtuins(SIRTs) are nicotinamide adenine dinucleotide(NAD^+)-dependent protein deacetylases,which regulate important biological processes ranging from apoptosis,age-associated pathophysiologies,adipocyte and muscle differentiation,and energy expenditure to gluconeogenesis.Very recently,sirtuin 5(SIRT5) has received considerable attention due to that it was found to have weak deacetylase activity but strong desuccinylase,demalonylase and deglutarylase activities,and it was also found to be associated with several human diseases such as cancer,Alzheimer's disease,and Parkinson's disease.In this review,we for the first time summarized the structure characteristics,known peptide and small-molecule inhibitors of SIRT5,extracted some clues from current available information and introduced some feasible,practical in silico methods,which might be useful in further efforts to develop new SIRT5 inhibitors. | Lingling Yang Xiaobo Ma Yanying He Chen Yuan Quanlong Chen Guobo Li Xianggui Chen | 2017 | Science China(Life Sciences)2017，60，3： | 7 |
| 9 | New technology to examine and improve the purity of hybrid rice with herbicide resistant gene显示文摘The herbicide resistant bar gene has been widely used as selectable marker genes in the study on plant genetic transformation. Owing to the integration of the gene into rice genome, transgenic rice was resistant to the herbicide Basta. Therefore, selection of transgenic plant and genetic analysis became easier. In the studies, bar gene was introduced as a genetic marker gene into rice restore line variety of two-line or three-line. Combined with conventional breeding method, the good herbicide resistant individual plant was derived as the new restore line for hybrid combination. After sprayed with Basta at seedling phase, the real hybrid rice that had herbicide resistance could grow normally, while the fake hybrid rice and weeds, having no bar gene, were killed by herbicide. The method described above helped rapidly to examine and improve the purity of hybrid rice. | Danian Huang Jingyang Li Shanqing Zhang Rui Xue Wei Yang Zhihua Hua Xiaobo Xie Xiaoling Wang | 1998 | Chinese Science Bulletin1998，43，9： | 7 |
| 10 | Mechanism and characteristics of thermal action of HMX explosive mixture containing high-efficiency fuel显示文摘In this study, the thermal stability and detonation properties of three types of explosives were investigated. Results indicated that nanoaluminum powder improved the detonation properties of HMX by increasing the specific surface area of HMX, which substantially increased the explosion heat and power. The decomposition temperatures of the three explosives containing aluminum hydride, ammonia borane, and nanoaluminum powder during slow cook-off at heating rates of 1.5 and 10°C min–1 were measured as 246°C and 241°C, 256°C and 261°C, and 238°C and 264°C, respectively. The explosives containing hydrogen storage materials swelled; however, the nanoaluminum powder was only slightly peeled off at the edge of the grains during cookoff. Differential scanning calorimetry(DSC) curves of the explosives containing hydrogen storage materials exhibited endothermic and exothermic peaks before the major exothermic reaction peak during the cook-off tests. In contrast, only one weak peak was observed in the DSC curve of the explosive containing nanoaluminum powder before the major exothermic reaction. In addition, the additives and adhesives catalyzed the slow cook-off decomposition, which caused the transformation of HMX crystals and accelerated the thermal decomposition reaction of HMX. The addition of high-density hydrogen storage materials to HMX resulted in detonation heats and explosion powers much greater than cure HMX. This improved performance was attributed to the hydrogen storage materials in the explosives participating in a secondary reaction in the reaction zone at the instant of the explosion, effectively realizing complementary lossless energy and thus greatly improving the explosive power of the explosives. | LIU JiPing YANG WeiWei LIU Ying LIU XiaoBo | 2019 | Science China(Technological Sciences)2019，62，4： | 6 |
| 11 | Source apportionment of VOCs in a typical medium-sized city in North China Plain and implications on control policy显示文摘Characteristics of atmospheric VOCs(volatile organic compounds) have been extensively studied in megacities in China, however, they are scarcely investigated in medium/smallsized cities in North China Plain(NCP).A comprehensive research on possible sources of VOCs was conducted in a medium-sized city of NCP, from May to September 2019.A total of 143 canister samples of 8 sites in Xuchang city were collected, and 57 VOC species were detected.The average VOC concentrations were 42.6 ± 31.6 μg/m3, with 53.7 ± 31.0 μg/m3 and 32.1 ± 27.8 μg/m^(3), in the morning and afternoon, respectively.Alkenes and aromatics contributed 80% of the total ozone formation potential(OFP).Aromatics accounted for more than 95% of secondary organic aerosol potential(SOAP).VOCs were dominated by the local emission with significant transport from the southeast direction.PMF analysis extracted 6 sources, which were combustion(33.1%), LPG usage(19.3%), vehicular exhaust & fuel evaporation(15.8%), solvent usage(15.2%), industrial(9.11%) and biogenic(7.51%), respectively and they contributed 33.4%, 17.6%, 12.9%, 18.6%, 9.28% and 8.22% to the OFP, respectively.Combustion and LPG usage were the dominant VOC sources;and combustion, solvent usage and LPG usage were the main sources of OFP in Xuchang city, which were different to megacities in China with a high contribution from vehicular exhaust, solvent usage and industry,suggesting specific control strategies on VOCs need to be implemented in medium-sized city such as Xuchang city. | Juanjuan Qin Xiaobo Wang Yanrong Yang Yuanyuan Qin Shaoxuan Shi Peihua Xu Rongzhi Chen Xueming Zhou Jihua Tan Xinming Wang | 2021 | Journal of Environmental Sciences2021，33，9： | 6 |
| 12 | The Medium Energy X-ray telescope (ME) onboard the Insight-HXMT astronomy satellite显示文摘The Medium Energy X-ray telescope(ME) is one of the three main telescopes on board the Insight hard X-ray modulation telescope(Insight-HXMT) astronomy satellite. ME contains 1728 pixels of Si-PIN detectors sensitive in 5-30 ke V with a total geometrical area of 952 cm^2. The application specific integrated circuit(ASIC) chip, VA32TA6, is used to achieve low power consumption and low readout noise. The collimators define three kinds of field of views(FOVs) for the telescope, 1°×4°, 4°×4°,and blocked ones. Combination of such FOVs can be used to estimate the in-orbit X-ray and particle background components.The energy resolution of ME is ~3 ke V at 17.8 ke V(FWHM) and the time resolution is 255 μs. In this paper, we introduce the design and performance of ME. | XueLei Cao WeiChun Jiang Bin Meng WanChang Zhang Tao Luo Sheng Yang ChunLei Zhang YuDong Gu Liang Sun XiaoJing Liu JiaWei Yang Xian Li Ying Tan ShaoZhen Liu YuanYuan Du FangJun Lu YuPeng Xu Ju Guan ShuangNan Zhang HuanYu Wang TiPei Li ChengMo Zhang XiangYang Wen JinLu Qu LiMing Song XiaoBo Li MingYu Ge YuPeng Zhou ShaoLin Xiong Shu Zhang YongJie Zhang ZeHao Cheng Fei Zhang MaoShun Li XiaoHua Liang Min Gao EnBo Yang XiaoHang Liu HongWei Liu YiJung Yang Fan Zhang | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，4： | 5 |
| 13 | A novel PTEN gene promoter mutation and untypical Cowden syndrome显示文摘Cowden syndrome (CS), an autosomal dominant disorder, is one of a spectrum of clinical disorders that have been linked to germline mutations in the phosphatase and tensin homolog (PTEN) gene. Although 70-80% of patients with CS have an identifiable germline PTEN mutation, the clinical diagnosis presents many challenges because of the phenotypic and genotypic variations. In the present study, we sequenced the exons and the promoter of PTEN gene, mutations and variations in the promoter and exons were identified, and a PTEN protein expression negative region was determined by immunohistochemistry (IHC). In conclusion, a novel promoter mutation we found in PTEN gene may turn off PTEN protein expression occasionally, leading to the disorder of PTEN and untypical CS manifestations. | Chen Liu Guangbing Li Rongrong Chen Xiaobo Yang Xue Zhao Haitao Zhao | 2013 | Chinese Journal of Cancer Research2013，25，3： | 5 |
| 14 | Preparation and properties of SiC honeycomb ceramics by pressureless sintering technology显示文摘SiC honeycomb ceramics with parallel channels and macroporous walls were prepared by combining extrusion molding with pressureless sintering technology in the presence of starch.The extrusion molding constructed honeycomb structure with parallel channels,while the starch formed spherical macropores on the channel walls.The density and bending strength of SiC honeycomb ceramics decreased with the increase of starch content,while the phase compositions did not vary with the starch content.The control in starch addition could adjust the pore structures on the channel walls of SiC honeycomb ceramics. | Xingzhong GUO Xiaobo CAI Lin ZHU Lingjie ZHANG Hui YANG | 2014 | Journal of Advanced Ceramics2014，3，1： | 5 |
| 15 | The correlation between nitrogen species in coke and NO_x formation during regeneration显示文摘Nitrogen oxides(NO x)emission during the regeneration of coked fluid catalytic cracking(FCC)catalysts is an environmental issue.In order to identify the correlations between nitrogen species in coke and different nitrogencontaining products in tail gas,three coked catalysts with multilayer structural coke molecules were prepared in a fixed bed with model compounds(o-xylene and quinoline)at first.A series of characterization methods were used to analyze coke,including elemental analysis,FT-IR,XPS,and TG–MS.XPS characterization indicates all coked catalysts present two types of nitrogen species and the type with a higher binding energy is related with the inner part nitrogen atoms interacting with acid sites.Due to the stronger adsorption ability on acid sites for basic nitrogen compounds,the multilayer structural coke has unbalanced distribution of carbon and nitrogen atoms between the inner part and the outer edge,which strongly affects gas product formation.At the early stage of regeneration,oxidation starts from the outer edge and the product NO can be reduced to N_2 in high CO concentration.At the later stage,the inner part rich in nitrogen begins to be exposed to O_2.At this period,the formation of CO decreases due to lack of carbon atoms,which is not bene ficial to the reduction of NO.Therefore,nitrogen species in the inner part of multilayer structural coke contributes more to NO X formation.Based on the multilayer structure model of coke molecule and its oxidation behavior,a possible strategy to control NO X emission was discussed merely from concept. | Teng Li Chaohe Yang Xiaobo Chen Libo Yao Wei Liang Xuemei Ding | 2016 | Chinese Journal of Chemical Engineering2016，24，5： | 5 |

| 17 | Provenance analysis of surface sediments in the Holocene mud area of the southern coastal waters off Shandong Peninsula,China显示文摘The sedimentary record of mud areas is an important carrier of information on the Holocene evolution of marine environments. Based on fine interpretations of the shallow stratigraphic section data, a small mud deposit area has been found in the southern coastal waters off Shandong Peninsula. This mud area is mainly distributed in coastal waters north of Laoshantou to the vicinity of Rushan Estuary. Overall, it is parallel to the coastline and spreads in a banded pattern, gradually thinning from offshore to the sea. The isopach map of depth distribution is parallel with the shoreline, and the depocenter lies in coastal waters of the Aoshan Bay where the maximum thickness is up to 22.5 m. Accelerator mass spectrometry(AMS) ^(14)C dating shows that the mud area was formed in the Holocene. The test data of surface sediments from the mud area, including particle size, mineral characteristics, and rare earth element contents, are used in comparisons with the composition of materials from the major surrounding medium and small rivers flowing into the sea and the Huanghe(Yellow) River. In this paper, the sedimentary characteristics and provenance of the mud deposit area are discussed. The results show that the formation of this mud area resulted from the joint action of the Huanghe River and surrounding rivers flowing into the sea. | ZHANG Xiaobo BI Shipu ZHANG Yong YANG Yuan LIU Shanshan KONG Xianghuai LI Xiaoyue CHU Hongxian | 2016 | Acta Oceanologica Sinica2016，35，5： | 5 |
| 18 | Sin1/mTORC2 regulate B cell growth and metabolism by activating mTORC1 and Myc显示文摘Proper control of B cell growth and metabolism is crucial for B-cell-mediated immunity,but the underlying molecular mechanisms remain incompletely understood.In this study,Sin1,a key component of mTOR complex 2(mTORC2),specifically regulates B cell growth and metabolism.Genetic ablation of Sin1 in B cells reduces the cell size at either the transitional stage or upon antigen stimulation and severely impairs metabolism.Sin1 deficiency also severely impairs B-cell proliferation,antibody responses,and anti-viral immunity.At the molecular level,Sin1 controls the expression and stability of the c-Myc protein and maintains the activity of mTORC1 through the Akt-dependent inactivation of GSK3 and TSC1/2,respectively.Therefore,our study reveals a novel and specific role for Sin1 in coordinating the activation of mTORC2 and mTORC1 to control B cell growth and metabolism. | Man Li Adam S.Lazorchak Xinxing Ouyang Huihui Zhang Hongzhi Liu Omotooke A.Arojo Lichong Yan Jingsi Jin Yuheng Han Guojun Qu Yuhong Fu Xiaocao Xu Xiaobo Liu Wenqian Zhang Zhengfeng Yang Chuan Ruan Qijun Wang Dou Liu Chuanxin Huang Lu Lu Shibo Jiang Fubin Li Bing Su | 2019 | Cellular & Molecular Immunology2019，16，9： | 4 |
| 19 | Effect of ziprasidone on QTc interval in Chinese patients with schizophrenia显示文摘Objective: To investigate the effect of ziprasidone on QTc in Chinese patients with schizophrenia. Methods: The study involved 27 patients with schizophrenia. Ziprasidone was initiated with 40 mg/day. From day 3 to day 7, the dose was increased gradually to 120-160 mg/d according to the effectiveness and tolerability. QTc values were measured at the beginning and month 6. Results: At the beginning of the 6 months treatment, the mean QTc interval of patients was(387.5±19.0) ms. At the end of the study, it was(402.9±23.6) ms. The difference has statistically significance(P<0.05). The mean QTc interval changed significantly throughout 6-months period but no one exceed the QTc dangerous limits. Significant correlation was found between QTc interval and the dose. Conclusion: In summary, our results suggest that ziprasidone has good tolerance in patient with schizophrenia despite its dose-related QTc prolongation. Ziprasidone have no pro-arrhythmic profile. | YANG Xiaobo YUAN Zuyi CAO Hongmei MA Xiancang | 2013 | Journal of Medical Colleges of PLA(China)2013，28，6： | 4 |
| 20 | Chemistry and biology of Pestalotiopsis-derived natural products显示文摘Species within the fungal genus Pestalotiopsis have become a topic of research in many microbial-chemical and pharmacological laboratories because they contain structurally complex,biologically active metabolites.This article is a follow-up to a previous review(Xu,Ebada,and Proksch,Fungal Divers 44:15–31,2010).It focuses particularly on new findings concerning the chemistry and bioactivity of Pestalotiopsis sp.,covering a period ranging from August 2010 to August 2013.Some 160 metabolites were isolated from Pestalotiopsis species during this period and their structures are reported within a biogenetic context.Bioassays showed antitumor,antifungal,and antimicrobial activities to be the most notable bioactivities of secondary metabolites isolated from this genus.The biogenetic pathways associated with the alkaloids,sesquiterpenes,quinines,xanthones,and lactones covered in this review are highlighted. | Jing Xu Xiaobo Yang Qiang Lin | 2014 | Fungal Diversity2014，，3： | 4 |
