| 1 | Geochemical characteristics of hadal sediment in the northern Yap Trench显示文摘Two sediment cores were retrieved in the hadal zone of the Yap Trench,and their concentrations of six major elements Mg,Al,Ca,Ti,Mn and Fe and nine trace elements Sr,Ba,Pb,V,Cr,Co,Ni,Cu and Zn were determined in inductively coupled plasma atomic emission spectrometry(ICP-AES).According to the vertical distribution profiles of the 15 elements,the correlation of their concentrations,the ratios of Ni/Co,V/Cr,Fe/Al,and Ti/Al,and morphological characteristics of the sediment samples,the implications of the depositional environment and the sediment provenance were analyzed.The results show that the ratio of Ni/Co in all depths of the two sediment cores were below 5,and the ratio of V/Cr were lower than 2,indicating that the depositional environment of the hadal zone in the trench was oxidative and might have inflow of the Antarctic bottom oxygen-rich water.The sediment samples on the eastern side of the trench were siliceous mud mainly composed of diatoms,radiolarian,and sponge needles from surface to deep layer.The vertical profile of the elements,the concentration of TOC and the fossil record indicated that the sediment sample from station Dive113 was well mixed from surface to bottom layer.Based on the correlation of concentrations of the elements,the morphological characteristics of the sediment,and the ratios of Fe/Al and Ti/Al,we inferred that the sediment in the hadal zone of the trench had terrestrial,volcanic,biological,and authigenic sources.Major source of the sediment in the eastern side of the trench were terrestrial;whereas the sediment in the western side of the trench received more volcaniclastic input. | HUANG Yuhuan SUN Chengjun YANG Guipeng YUE Xin’an JIANG Fenghua CAO Wei YIN Xiaofei GUO Chaonan NIU Jiaohong DING Haibing | 2020 | Journal of Oceanology and Limnology2020，38，3： | 3 |
| 2 | Effect of Traditional Chinese Medicine plus narrow-band medium-wave ultraviolet B radiation on moderate-to-severe psoriasis vulgaris in a case series显示文摘OBJECTIVE: To investigate the efficacy and safety of Traditional Chinese Medicine (TCM) therapy combined with ultraviolet B light therapy in the treatment of moderate-to-severe psoriasis. METHODS: Patients with moderate-to-severe psoriasis (skin lesion area > 10% of the body surface area) for 2 consecutive years were treated with TCM (oral and external use of herbal medicines, acupuncture, and herbal bathing) and narrow-band medium-wave ultraviolet B light treatment for 12 weeks. The treatment effect was evaluated based on the Psoriasis Area Severity Index (PASI), the achievement of a 50% reduction in the PASI (PASI50), the achievement of a 75% reduction in the PASI (PASI75), pruritus score, Dermatology Life Quality Index, and safety. RESULTS: A total of 95 outpatients were enrolled, and 92 subjects (96.8%) completed the 12-week treatment course. At baseline, the average proportion of the body surface area covered by skin lesions was 12.4%, and the average PASI was 17.7. All patients had previously been treated with conventional medicine (89.1% of patients received ultraviolet light treatment, 50.0% received glucocorticoids, and 21.7% received acitretin). After the 12-week treatment course, 22 patients (23.9%) achieved PASI75, and 43 (46.7%) achieved PASI50. The post-treatment pruritus score and Dermatology Life Quality Index of all treated patients were significantly lower than the respective baseline values (P < 0.0001). No adverse effects were detected by the monitoring of blood, urine, stools, liver and kidney function, and echocardiography.CONCLUSION: Comprehensive therapy comprising TCM therapy combined with ultraviolet B light therapy achieved good outcomes for patients with moderate-to-severe psoriasis. | Li Tiantian Zhou Dongmei Xu Xuying Qu Jianhua Jiang Chunyan Lan Haibing Lou Weihai Chen Weiwen Jin Li Liu Rongqi Liu Zhiyong Zhang Cang Duan Lanhua Bohua Li Xu Jingna Zhou Tao Jiang Xi Cao Wei Zhang Guangzhong Liu Jianping Sun Liyun Wang Ping | 2019 | Journal of Traditional Chinese Medicine2019，39，5： | 2 |
| 3 | Distribution characteristics of lipids in hadal sediment in the Yap Trench显示文摘In this study,cored sediment samples collected by the Jiaolong Submersible at 6779 m depth from the hadal zone of the Yap Trench in May 2016 were sliced in 1-cm interval from top to bottom,and lipids in each sediment layer were quantitatively and qualitatively analyzed.The vertical distribution profiles of the lipids in the sediment sample,their main existing forms,and their possible sources were investigated.The results show that the concentration of lipid in the surface sediment was the highest with the carbon number from 12 to 27,dominated by medium and short-chain lipids.The total concentration of fatty acids in surface sediment was much higher than those in the offshore and deep-sea areas,being up to 325.77μg/g due to the funnel effect caused by the“V”terrain of the trench.Fatty acid 18:0 was the most abundant lipids in the sediment sample.Abnormal high concentrations of fatty acid 18:1ω7 and alkanes indicated the existence of hydrothermal fluids in the study area.In addition,saturated fatty acids and monounsaturated fatty acids existed mainly in free form,and polyunsaturated fatty acids existed mainly in bound form.Most of the alkanes were in bound form,and their major source was autochthounous input.The carbon number of alcohols in the sediment sample ranged from 12 to 20,mainly existed in bound form.The source of fatty acids was mainly autochthonous input,and the neutral lipids had both marine and terrestrial origin.This is the first study of lipids in hadal sediment of the Yap Trench.The results will promote deeper understanding of organic carbon cycle in marine environment. | YAN Yixin SUN Chengjun HUANG Yuhuan CAO Wei JIANG Fenghua YANG Guipeng DING Haibing | 2020 | Journal of Oceanology and Limnology2020，38，3： | 2 |
| 4 | Maternal genetic history of ancient Tibetans over the past 4000 years显示文摘The settlement of the Tibetan Plateau epitomizes human adaptation to a high-altitude environment that poses great challenges to human activity.Here,we reconstruct a 4000-year maternal genetic history of Tibetans using 128 ancient mitochondrial genome data from 37 sites in Tibet.The phylogeny of haplotypes M9a1a,M9a1b,D4g2,G2a’c,and D4i show that ancient Tibetans share the most recent common ancestor with ancient Middle and Upper Yellow River populations around the Early and Middle Holocene.In addition,the connections between Tibetans and Northeastern Asians vary over the past 4000 years,with a stronger matrilineal connection between the two during 4000 BPe3000 BP,and a weakened connection after 3000 BP,that are coincident with climate change,followed by a reinforced connection after the Tubo period(1400 BPe1100 BP).Besides,an over 4000-year matrilineal continuity is observed in some of the maternal lineages.We also find the maternal genetic structure of ancient Tibetans is correlated to the geography and interactions between ancient Tibetans and ancient Nepal and Pakistan populations.Overall,the maternal genetic history of Tibetans can be characterized as a long-term matrilineal continuity with frequent internal and external population interactions that are dynamically shaped by geography,climate changes,as well as historical events. | Ganyu Zhang Can Cui Shargan Wangdue Hongliang Lu Honghai Chen Lin Xi Wei He Haibing Yuan Tinley Tsring Zujun Chen Feng Yang Tashi Tsering Shuai Li Norbu Tashi Tsho Yang Yan Tong Xiaohong Wu Linhui Li Yuanhong He Peng Cao Qingyan Dai Feng Liu Xiaotian Feng Tianyi Wang Ruowei Yang Wanjing Ping Ming Zhang Xing Gao Yichen Liu Wenjun Wang Qiaomei Fu | 2023 | Journal of Genetics and Genomics2023，50，10： | 1 |
| 5 | Area-efficient transient power-rail electrostatic discharge clamp circuit with mis-triggering immunity in a 65-nm CMOS process显示文摘A novel, area-efficient transient power-rail electrostatic discharge(ESD) clamp circuit is proposed in this work. Current-mirror capacitors are used to reduce the layout area. Logic threshold voltages of inverters are modified to ensure a fully active on-state for the clamp device in ESD conditions. The proposed circuit reduces the layout area by about 56% compared with a circuit without current-mirror capacitors. Transmission line pulse(TLP) test results based on a 65-nm CMOS process demonstrate that the proposed circuit is an efficient on-chip ESD protection scheme for this process. In addition, the proposed circuit achieves a good immunity to mis-triggering with respect to fast power-up transitions. | Yuan WANG Guangyi LU Haibing GUO Jian CAO Song JIA Xing ZHANG | 2016 | Science China(Information Sciences)2016，59，4： | 1 |

| 8 | Biodegradation Behavior of Starch in Simulated White Water System of Old Corrugated Cardboard Pulping Process显示文摘Considering the serious barriers/issues induced by the accumulated starch generated in white water system of old corrugated cardboard(OCC)pulping process,large amounts of accumulated starch in white water would be decomposed by microorganisms and could not be utilized,thereby resulting in severe resource wastage and environmental pollution.This study mainly explored the effects of biodegradation/hydrolysis conditions of the two types of starch substrates(native starch and enzymatically(α-amylase)hydrolyzed starch),which were treated via microorganism degradation within the simulated white water from OCC pulping system and their biodegradation products on the key properties were characterized via X-ray diffraction(XRD),Fourier-transform infrared spectroscopy(FT-IR),and gel permeation chromatography(GPC)technologies.The effects of system temperature,pH value,starch concentration,and biodegradation time on starch biodegradation ratio and the characteristics of obtained biodegradated products from the two types of starches were studied.In addition,the effect ofα-amylase dosage on the biodegradation ratio of enzymatically hydrolyzed starch and its properties was investigated.It was found that the native starch presented a maximal degradation ratio at a system temperature of 55℃and pH value range of 5-7,respectively,the corresponding starch concentration within simulated white water system was 200 mg/L.Whereas the enzymatically hydrolyzed starch exhibited a highest degradation ratio at a system temperature of 50℃and pH value of 5.5,respectively,and the corresponding starch concentration within simulated white water system was 100 mg/L.It was verified that native starch is more readily bio-hydrolyzed and biodegradation-susceptive by microorganisms in simulated white water system of OCC pulping process,while the enzymatically hydrolyzed starch exhibits better biodegradation/hydrolysis resistance to the microbial degradation than that of native starch.This study provides a practical and interesting approach to investigate the starch hydrolysis or biodegradation behaviors in white water system of OCC pulping process,which would greatly contribute to the full recycling and valorized application of starch as a versatile additive during paperboard production. | Jinhuan Guo Liqin Liu Xiaohong Zhang Zhengbai Cheng Shuangxi Nie Haibing Cao Na Li Md Manik Mian Xingye An Hongbin Liu | 2023 | Paper And Biomaterials2023，8，1： | 0 |
| 9 | Vertical variations and composition of dissolved free amino acid in the seawater of the Yap Trench in the western Pacific Ocean显示文摘The composition and concentration of dissolved free amino acid(DFAA)of seawater samples collected in May 2016 from the surface to the hadal zone of the northern region of the Yap Trench were analyzed by pre-column derivatization of o-phthalaldehyde.Results show that the average concentration of DFAA in the study area was 0.47±0.36μmol/L.In different sampling stations,the concentrations of DFAA with water depth showed complex variation patterns.At the sediment-seawater interface,the concentrations of DFAA in the western side of the trench were obviously higher than that in its eastern side.In the study area,there were no significant correlations between the concentrations of DFAA and the environmental parameters such as concentrations of chlorophyll a(Chl a),dissolved oxygen(DO),pH,and dissolved inorganic nitrogen(DIN),indicating that the concentrations of DFAA in seawater of the trench are affected by many factors,such as photosynthesis,respiration,temperature,pressure,illumination,and circulation.The dominant DFAA are similar in different water layers of sampling stations,including aspartic acid(Asp),glutamic acid(Glu),glycine(Gly),and serine(Ser).The composition of different amino acids,and the relative abundance of acidic,basic,and neutral amino acids might be related to the sources and consumption of various amino acids.Nine pairs of amino acids in the DFAA showed significantly positive relationship by correlation matrix analysis,suggesting that they might share similar biogeochemical processes.The degradation index(DI)of the DFAA in seawater of the Yap Trench could reflect the degradation,source,and freshness of DFAA in the trench to some extents.This is a preliminary study of amino acids from sea surface to hadal zone in the ocean,more works shall be done in different trenches to reveal their biogeochemical characte ristics in extreme marine environme nts. | Jiaohong NIU Chengjun SUN Bo YANG Lei XIE Fenghua JIANG Wei CAO Yan CHEN Haibing DING Yuhuan HUANG Xianchi GAO | 2023 | Journal of Oceanology and Limnology2023，41，1： | 0 |
| 10 | Design of B/N Co-doped micro/meso porous carbon electrodes from CNF/BNNS/ZIF-8 nanocomposites for advanced supercapacitors显示文摘Boron(B)and nitrogen(N)co-doped 3D hierarchical micro/meso porous carbon(BNPC)were successfully fabricated from cellulose nanofiber(CNF)/boron nitride nanosheets(BNNS)/zinc-methylimidazolate framework-8(ZIF-8)nanocomposites prepared by 2D BNNS,ZIF-8 nanoparticles,and wheat straw based CNFs.Herein,CNF/ZIF-8 acts as versatile skeleton and imparts partial N dopant into porous carbon structure,while the introduced BNNS can help strengthen the hierarchical porous superstructure and endow abundant B/N co-dopants within BNPC matrix.The obtained BNPC electrode possesses a high specific surface area of 505.4 m2/g,high B/N co-doping content,and desirable hydrophilicity.Supercapacitors assembled with BNPC-2(B/N co-doped porous carbon with a CNF/BNNS mass ratio of 1꞉2)electrodes exhibited exceptional electrochemical performance,demonstrating high capacitance stability even after 5000 charge-discharge cycles.The devices exhibited outstanding energy density and power density,as well as the highest specific capacitance of 433.4 F/g at 1.0 A/g,when compared with other similar reports.This study proposes a facile and sustainable strategy for efficiently fabrication of rich B/N co-doped hierarchical micro/meso porous carbon electrodes from agricultural waste biomass for advanced supercapacitor performance. | Zhen Shang Xingye An Shuangxi Nie Na Li Haibing Cao Zhengbai Cheng Hongbin Liu Yonghao Ni Liqin Liu | 2023 | Journal of Bioresources and Bioproducts2023，8，3： | 0 |

| 12 | Water molecules bonded to the carboxylate groups at the inorganic-organic interface of an inorganic nanocrystal coated with alkanoate ligands显示文摘High-quality colloidal nanocrystals are commonly synthesized in hydrocarbon solvents with alkanoates as the most common organic ligand.Water molecules with an approximately equal number of surface alkanoate ligands are identified at the inorganic-organic interface for all types of colloidal nanocrystals studied,and investigated quantitatively using CdSe nanocrystals as the model system.Carboxylate ligands are coordinated to the surface metal ions and the first monolayer of water molecules is found to bond to the carboxylate groups of alkanoate ligands through hydrogen bonds.Additional monolayer(s)of water molecules can further be adsorbed through hydrogen bonds to the first monolayer of water molecules.The nearly ideal environment for hydrogen bonding at the inorganic-organic interface of alkanoate-coated nanocrystals helps to rapidly and stably enrich the interface-bonded water molecules,most of which are difficult to remove through vacuum treatment,thermal annealing and chemical drying.The water-enriched structure of the inorganic-organic interface of high-quality colloidal nanocrystals must be taken into account in order to understand the synthesis,processing and properties of these novel materials. | Jiongzhao Li Weicheng Cao Yufei Shu Haibing Zhang Xudong Qian Xueqian Kong Linjun Wang Xiaogang Peng | 2022 | National Science Review2022，9，2： | 0 |
| 13 | Characteristics of dissolved sugars in the Southern Yap Trench from sea surface to hadal zone显示文摘2,4,6-Tripyridine-s-triazine(TPTZ)spectrophotometric method was applied to determine the concentrations of dissolved monosaccharides(MCHO),polysaccharides(PCHO),and total carbohydrate(TCHO)in seawater samples collected from sea surface to hadal zone and sediment-seawater interface of the Southern Yap Trench in the Western Pacific Ocean.Results show that the concentrations of MCHO,PCHO,and TCHO ranged from 6.3 to 22.3μmol C/L,1.1 to 25.4μmol C/L,and 12.1 to 44.9μmol C/L,respectively,from the euphotic layer to the hadal zone of the trench.At different sampling stations,the concentrations of MCHO,PCHO,and TCHO in the seawater showed complex vertical variation characteristics,but the overall variation trends were decreasing with water depth.In the Southern Yap Trench,the maximum concentration of MCHO in the seawater appeared in the euphotic layer,and the minimum in the hadal zone.The maximum concentration of PCHO appeared in the euphotic layer,and the minimum in the bathypelagic layer.The water layer where the maxima and minima of the average concentration of TCHO appeared was consistent with that of PCHO.PCHO was the major component of TCHO in the seawater of the Southern Yap Trench.In the seawater from the sediment-seawater interface,the concentrations of MCHO,PCHO,and TCHO ranged from 8.4 to 10.6μmol C/L,3.8 to 5.8μmol C/L,and 12.2 to 15.2μmol C/L,respectively,and MCHO was the major component of TCHO.The key factors affecting the concentration and existing forms of dissolved sugars in the seawater of the Southern Yap Trench included photosynthesis,respiration,polysaccharide hydrolysis,adsorption and desorption of particulate matter,trench“funnel effect”,deep ocean currents,sediment resuspension,and etc.This study provided fundamental data about labile organic matter in abyss and hadal zone of marine environment,which is significant for further understanding of deep-sea organic carbon cycle. | Dong CUI Chengjun SUN Chaonan GUO Wei CAO Fenghua JIANG Haibing DING | 2023 | Journal of Oceanology and Limnology2023，41，6： | 0 |
