1Types,Characteristics and Significances of Migrating Pathways of Gas-bearing Fluids in the Shenhu Area,Northern Continental Slope of the South China Sea显示文摘The first marine gas hydrate expedition in China has been conducted by Guangzhou Marine Geological Survey in the Shenhu Area, northern continental slope of the South China Sea. Previous study has analyzed the P-T conditions, geophysical anomalies and saturation calculations of these gas hydrates, but has not documented in detail the migration of gas-bearing fluids in the study area. Based on the interpretations of 2D/3D seismic data, this work identified two types of migration pathways for gas-bearing fluids in the Shenhu area, i.e., vertical and lateral pathways. The vertical pathways(largescale faults, gas chimneys and mud diapirs) presented as steep seismic reflection anomalies, which could be traced downward to the Eocene source rocks and may penetrate into the Late Miocene strata. The deeper gases/fluids might be allowed migrating into the shallower strata through these vertical conduits. However, the distributions showed distinct differences between these pathways. Large-scale faults developed only in the north and northeast of the Shenhu area, while in the drilling area gas chimneys were the sole vertical migration pathways. Since the Pliocene, normal faults, detachment faults and favorable sediments have constituted the lateral pathways in the Shenhu gas hydrate drilling area. Although these lateral pathways were connected with gas chimneys, they exerted different effects on hydrate formation and accumulation. Gas-bearing fluids migrated upward along gas chimneys might further migrate laterally because of the normal faults, thereby enlarging the range of the chimneys. Linking gas chimneys with the seafloor, the detachment faults might act as conduits for escaping gases/fluids. Re-deposited sediments developed at the early stage of the Quaternary were located within the gas hydrate stability zone, so hydrates would be enriched in these favorable sediments. Compared with the migration pathways(large-scale faults and mud diapirs) in the LW3-1 deep-sea oil/gas field, the migration efficiency of the vertical pathways(composed of gas chimneys) in the gas hydrate drilling area might be relatively low. Description and qualitative discrimination of migration pathways in the Shenhu gas hydrate drilling area are helpful to further understand the relationship between good-quality deep source rocks and shallow, mainly biogenicallyproduced, hydrates. As the main source rocks of the Baiyun sag, lacustrine mudstones in the Wenchang and Enping Formations may provide thermogenic methane. Gas chimneys with relatively low migration efficiency created the vertical pathways. Caused by the Dongsha tectonic movement, the release of overpressured fluids might reduce the vertical migration rates of the thermogenic methane. The thick bathyal/abyssal fine-grained sediments since the Late Miocene provided migration media with low permeability. These preconditions may cause carbon isotopic fractionation ofthermogenic methane during long-distance vertical migrations. Therefore, although geochemical analyses indicate that the methane forming gas hydrate in the Shenhu area was mainly produced biogenically, or was mixed methane primarily of microbial origin, thermogenic methane still contribute significantly.SU Ming SHA Zhibin ZHANG Cuimei WANG Hongbin WU Nengyou YANG Rui LIANG Jinqiang QIAO Shaohua CONG Xiaorong LIU Jie 2017Acta Geologica Sinica(English Edition)2017,91,1:16

3Effect of moxa-burning heat stimulating Liangmen(ST 21) and Zusanli(ST 36) on proliferation and apoptosis signaling proteins in rats with stress-induced gastric ulcer显示文摘OBJECTIVE: To observe the effect of moxa-burning heat stimulating acupoints of Liangmen(ST 21)and Zusanli(ST 36) on the proliferation and apoptosis signaling proteins in rats with stress-induced gastric ulcer.METHODS: Forty rats were randomly divided into four groups: negative control(NC), ulcer control(UC), acupoints of stomach meridian(ASM), and acupoints control(AC). The acute gastric ulcer model was established by bound and water immersion.Rats in NC and UC groups didn't receive any moxa-burning heat stimulating treatment, while rats in ASM and AC groups were treated with buringmoxa heat stimulating the acupoints of Liangmen(ST 21) and Zusanli(ST 36) and their controlled points, respectively. Rats in all groups were sacrificed after 12 consecutive days treatment. The ulcer index was evaluated by using Guth's method.The expression of tumor necrosis factor-alpha(TNF-α), apoptotic protease activating facter-1(Apaf-1), Caspase-3, p21 activated kinase 1(PAK1),extracellular regulated protein kinases 2(ERK2),phosphorylated ERK2(p ERK2), phosphoinositide3-kinase(PI3K) and RAC-alpha serine/threonine-protein kinase(Akt) in gastric mucosa was detected by enzyme linked immunosorbent assay(ELISA).RESULTS: Compared with UC group, the ulcer index of ASM and AC groups decreased, and the injured gastric mucosa was improved, the expression of TNF-α, Apaf-1 and Caspase-3 in gastric mucosa was significantly reduced(P < 0.05), while the ex-pression of PAK1, ERK2, p ERK2, PI3 K and Akt in gastric mucosa was significantly increased(P < 0.05).And ASM showed better effect than AC group(P <0.05).CONCLUSION: Moxa-burning Heat stimulating of Liangmen(ST 21) and Zusanli(ST 36) could promote the recovery of gastric mucosal lesion probably by inhibiting cell apoptosis and promoting cell proliferation in stress-induced gastric ulcer.Peng Li Wang Yadong Chang Xiaorong Wu Huangan Liu Mi Ma Fuqiang Wang Hong Chen Jiaolong Wang Chao Quan Renfu Yang Zongbao 2016Journal of Traditional Chinese Medicine2016,36,3:9
4Platelet-rich plasma accelerates skin wound healing by promoting re-epithelialization显示文摘Background:Autologous platelet-rich plasma(PRP)has been suggested to be effective for wound healing.However,evidence for its use in patients with acute and chronic wounds remains insufficient.The aims of this study were to comprehensively examine the effectiveness,synergy and possible mechanism of PRP-mediated improvement of acute skin wound repair.Methods:Full-thickness wounds were made on the back of C57/BL6 mice.PRP or saline solution as a control was administered to the wound area.Wound healing rate,local inflammation,angiogenesis,re-epithelialization and collagen deposition were measured at days 3,5,7 and 14 after skin injury.The biological character of epidermal stem cells(ESCs),which reflect the potential for re-epithelialization,was further evaluated in vitro and in vivo.Results:PRP strongly improved skin wound healing,which was associated with regulation of local inflammation,enhancement of angiogenesis and re-epithelialization.PRP treatment significantly reduced the production of inflammatory cytokines interleukin-17A and interleukin-1β.An increase in the local vessel intensity and enhancement of re-epithelialization were also observed in animals with PRP administration and were associated with enhanced secretion of growth factors such as vascular endothelial growth factor and insulin-like growth factor-1.Moreover,PRP treatment ameliorated the survival and activated the migration and proliferation of primary cultured ESCs,and these effects were accompanied by the differentiation of ESCs into adult cells following the changes of CD49f and keratin 10 and keratin 14.Conclusion:PRP improved skin wound healing by modulating inflammation and increasing angiogenesis and re-epithelialization.However,the underlying regulatory mechanism needs to be investigated in the future.Our data provide a preliminary theoretical foundation for the clinical administration of PRP in wound healing and skin regeneration.Pengcheng Xu Yaguang Wu Lina Zhou Zengjun Yang Xiaorong Zhang Xiaohong Hu Jiacai Yang Mingying Wang Binjie Wang Gaoxing Luo Weifeng He Biao Cheng 2020Burns & Trauma2020,8,1:8

7Gene fusions and chimeric RNAs,and their implications in cancer显示文摘Gene fusions are appreciated as ideal cancer biomarkers and therapeutic targets.Chimeric RNAs are traditionally thought to be products of gene fusions,and thus,also cancerspecific.Recent research has demonstrated that chimeric RNAs can be generated by intergenic splicing in the absence of gene fusion,and such chimeric RNAs are also found in normal physiology.These new findings challenge the traditional theory of chimeric RNAs exclusivity to cancer,and complicates use of chimeric RNAs in cancer detection.Here,we provide an overview of gene fusions and chimeric RNAs,and emphasize their differences.We note that gene fusions are able to generate chimeric RNAs in accordance with the central dogma of biology,and that chimeric RNAs may also be able to influence the generation of the gene fusions per the“horse before the cart”hypothesis.We further expand upon the“horse before the cart”hypothesis,summarizing current evidence in support of the theory and exploring its potential impact on the field.Hao Wu Xiaorong Li Hui Li 2019Genes & Diseases2019,6,4:4
8From deep basin gas to diagenetic trap—An example from the Yulin Gas Field in the Ordos Basin显示文摘In the updip portion of the Yulin Gas Field in the Ordos Basin, there are no any structural, stratigraphic and sedimentary lithologic seals. Using thin-section petrography, ultraviolet fluorescence microscopy, micro-thermometry and Raman microspectrometry, this paper finds out the diagenetic trap and studies the diagenetic history of this field. It was revealed that three phases of diagenesis and hydrocarbon charging happened in late Triassic, late Jurassic and the end of early Cretaceous respectively. In the first two phases, acid geofluid entered the reservoir and caused dissolution and cementation. Although the porosities had been increased, further compaction accompanying re-subsidence resulted in tight sandstone and conglomerates. Till the end of the early Cretaceous, bulk of gas migrated into the tight reservoir. Cementation, however, kept on in the updip portion of this field due to low gas saturation and formed the diagenetic trap. The mechanism for gas accumulation was changed from deep basin gas to diagenetic trap, which offers a sealing condition that can retain gas for much longer time.ZHANG LiuPing LUO XiaoRong MA XinHua CHEN MengJin WU MingHui 2007Chinese Science Bulletin2007,52,21:4
9Mitochondrial protein sulfenation during aging in the rat brain显示文摘There is accumulating evidence that cysteine sulfenation (cys-SOH) in proteins plays an important rolein cellular response to oxidative stress. The purpose of the present study was to identify mitochondrialproteins that undergo changes in cys-SOH during aging. Studies were conducted in rats when they were5 or 30 months of age. Following blocking of free protein thiols with N-ethylmaleimide, protein sulfenicacids were reduced by arsenite to free thiol groups that were subsequently labeled with biotin-maleimide. Samples were then comparatively analyzed by two-dimensional Western blots, and proteinsshowing changes in sulfenation were selectively identified by mass spectrometry peptide sequencing.As a result, five proteins were identified. Proteins showing an age-related decrease in sulfenationinclude pyruvate carboxylase and pyruvate dehydrogenase; while those showing an age-relatedincrease in sulfenation include aconitase, mitofilin, and tubulin (α-1). Results of the present studyprovide a general picture of mitochondrial protein sulfenation in brain oxidative stress and implicatethe involvement of protein sulfenation in overall decline of mitochondrial function during brain aging.Xiaorong Yang Jinzi Wu Siqun ling Michael J.

10Novel high voltage RESURF Al GaN/GaN HEMT with charged buffer layer显示文摘A novel reduced surface field (RESURF) Al GaN /GaN high electron mobility transistor(HEMT)with charged buffer layer is proposed. Its breakdown mechanism and on-state characteristics are investigated.The HEMT features buried Fluorine ions in the GaN buffer layer both under the Drift and the Gate region (FDG). The section of FDG under the drift region (FD) not only reduces the electric field (E-field) peak at the gate edge but also enhances the E-field in the drift region by the assisted depletion, leading to a significant improvement in breakdown voltage (BV). Moreover, the section of FDG under the gate (FG) enhances the back barrier and effectively prevents electron injecting from the source to form leakage current, thus a higher BV is achieved. The BV of the proposed HEMT sharply increases to 750 V from 230 V of conventional AlGaN /GaN HEMT with the same dimensional parameters, and the specific on-resistance (Ron,sp) just increases to1.21 m?·cm^2from 1.01 m?·cm^2.Jiayun XIONG Chao YANG Jie WEI Junfeng WU Bo ZHANG Xiaorong LUO 2016Science China(Information Sciences)2016,59,4:2
11OTUD5 promotes innate antiviral and antitumor immunity through deubiquitinating and stabilizing STING显示文摘Stimulator of interferon genes(STING)is an adaptor protein that is critical for effective innate antiviral and antitumor immunity.The activity of STING is heavily regulated by protein ubiquitination,which is fine-tuned by both E3 ubiquitin ligases and deubiquitinases.Here,we report that the deubiquitinase OTUD5 interacts with STING,cleaves its K48-linked polyubiquitin chains,and promotes its stability.Consistently,knockout of OTUD5 resulted in faster turnover of STING and subsequently impaired type I IFN signaling following cytosolic DNA stimulation.More importantly,Lyz2-Cre Otud5^(fl/Y) mice and CD11-Cre Otud5^(fl/Y) mice showed more susceptibility to herpes simplex virus type 1(HSV-1)infection and faster development of melanomas than their corresponding control littermates,indicating that OTUD5 is indispensable for STING-mediated antiviral and antitumor immunity.Our data suggest that OTUD5 is a novel checkpoint in the cGAS-STING cytosolic DNA sensing pathway.Yunyun Guo Fei Jiang Lingli Kong Haifeng Wu Honghai Zhang Xiaorong Chen Jian Zhao Baoshan Cai Yanqi Li Chunhong Ma Fan Yi Lei Zhang Bingyu Liu Yi Zheng Lingqiang Zhang Chengjiang Gao 2021Cellular & Molecular Immunology2021,18,8:2

13Natural multimodal interaction in immersive flow visualization显示文摘In the immersive flow visualization based on virtual reality,how to meet the needs of complex professional flow visualization analysis by natural human–computer interaction is a pressing problem.In order to achieve the natural and efficient human–computer interaction,we analyze the interaction requirements of flow visualization and study the characteristics of four human–computer interaction channels:hand,head,eye and voice.We give out some multimodal interaction design suggestions and then propose three multimodal interaction methods:head&hand,head&hand&eye and head&hand&eye&voice.The freedom of gestures,the stability of the head,the convenience of eyes and the rapid retrieval of voices are used to improve the accuracy and efficiency of interaction.The interaction load is balanced by multimodal interaction to reduce fatigue.The evaluation shows that our multimodal interaction has higher accuracy,faster time efficiency and much lower fatigue than the traditional joystick interaction.Chengyu Su Chao Yang Yonghui Chen Fupan Wang Fang Wang Yadong Wu Xiaorong Zhang 2021Visual Informatics2021,5,4:1
