1Exosomes as therapeutic drug carriers and delivery vehicles across biological membranes:current perspectives and future challenges显示文摘Exosomes are small intracellular membrane-based vesicles with different compositions that are involved in several biological and pathological processes. The exploitation of exosomes as drug delivery vehicles offers important advantages compared to other nanoparticulate drug delivery systems such as liposomes and polymeric nanoparticles; exosomes are non-immunogenic in nature due to similar composition as body's own cells. In this article, the origin and structure of exosomes as well as their biological functions are outlined. We will then focus on specific applications of exosomes as drug delivery systems in pharmaceutical drug development. An overview of the advantages and challenges faced when using exosomes as a pharmaceutical drug delivery vehicles will also be discussed.Dinh Ha Ningning Yang Venkatareddy Nadithe 2016Acta Pharmaceutica Sinica B2016,6,4:104
2Antimony speciation in the environment:Recent advances in understanding the biogeochemical processes and ecological effects显示文摘Antimony(Sb) is a toxic metalloid, and its pollution has become a global environmental problem as a result of its extensive use and corresponding Sb-mining activities. The toxicity and mobility of Sb strongly depend on its chemical speciation. In this review, we summarize the current knowledge on the biogeochemical processes(including emission, distribution,speciation, redox, metabolism and toxicity) that trigger the mobilization and transformation of Sb from pollution sources to the surrounding environment. Natural phenomena such as weathering, biological activity and volcanic activity, together with anthropogenic inputs, are responsible for the emission of Sb into the environment. Sb emitted in the environment can adsorb and undergo redox reactions on organic or inorganic environmental media, thus changing its existing form and exerting toxic effects on the ecosystem. This review is based on a careful and systematic collection of the latest papers during 2010–2017 and our research results, and it illustrates the fate and ecological effects of Sb in the environment.Mengchang He Ningning Wang Xiaojing Long Chengjun Zhang Congli Ma Qianyun Zhong Aihua Wang Ying Wang Aneesa Pervaiz Jun Shan 2019Journal of Environmental Sciences2019,31,1:40

4Status quo of soil petroleum contamination and evolution of bioremediation显示文摘Along with the rapid development of oil industries internationally,petroleum prospecting and exploitation activities are growing intensively.Especially in China,with the fastest economic growth in the world and shortage of petroleum resources,we are leading the practices of petroleum deep exploitation.Obviously,the risk of damage to the natural environment from these activities is high.Oil contamination in soils and groundwater is becoming a big issue along with pesticide pollution,which makes organic pollution prevention and control (OPPC) much more complex.In this paper,based on recent research on oil-contaminated soil at home and abroad,we make comments on the remediation technologies for polluted soil,emphasizing bioremediation techniques and degradation mechanisms in order to push forward research into bound organic pollution prevention and control (OPPC),especially in China.Du Weidong Wan Yunyang Zhong Ningning Fei Jiajia ZhangZhihuan Chen Lijun Hao Jiming 2011Petroleum Science2011,8,4:19
5Correlation of burial organic carbon and paleoproductivity in the Mesoproterozoic Hongshuizhuang Formation, northern North China显示文摘In general, total organic carbon (TOC) is directly used as a proxy for paleoproductivity, however, it is not only affected by paleoproductivity, but also controlled by redox conditions and terrigenous detrital matter influx. Major and trace elements were analysed with the purpose of investigating the redox potential and paleoproductivity during deposition of the Hongshuizhuang Formation. In the present study, C-S relationship, V/Cr ratio and Mo concentration indicate that the dolomites were deposited in oxic environments, however, most of the black shales were accumulated in euxinic environments. P/Ti values in the Hongshuizhuang samples can be compared with those in the Japanese Ubara Permian-Triassic section which were regarded to be deposited under a moderate to high paleoproductivity. Ba/Al values are slightly lower than that of the laminated sediments from the continental margins of Central California (CCAL) which were thought to be accumulated under a high paleoproductivity. These results indicate that the paleoproductivity was moderate to high during deposition of the Hongshuizhuang Formation. Burial organic carbon shows positive correlations with V/Cr and Mo, but shows only weakly or no correlation with P/Ti and Ba/Al, respectively, suggesting that although the paleoproductivity was moderate to high during deposition of the Hongshuizhuang Formation, its organic-rich sediments were predominantly controlled by redox conditions and had no direct relationship with paleoproductivity.LUO QingYong ZHONG NingNing ZHU Lei WANG YanNian QIN Jing QI Lin ZHANG Yi MA Yong 2013Chinese Science Bulletin2013,58,11:17
6Design and experiment on intelligent fuzzy monitoring system for corn planters显示文摘When sowing summer corn without tillage,it is necessary to ensure that the furrow opener is free from straw congestion and that the spacing of the sowing can be adjusted according to the breeds of corn and the preset seeding rate per acre.On the basis of the structural features of newly developed no-tillage corn fertilizers,an intelligent fuzzy monitoring system for corn planters was developed in this study.The system facilitates automatic control of the spacing adjustment and the status monitor for the fertilizer tank,seed tank,and seeding orifice.According to the preset number of rows,line spacing,number of plants per acre,and seed germination rate,the control rate can be calculated through designing in surveillance software.The control rate is output to the fuzzy controller through the digital output module of the CAN bus.Fuzzy control is applied to the DC motor for stepless adjustment of the spacing.A system for video surveillance of the working status of a planter is developed for displaying a real-time video image of the planter operation and achieving an anti-congestion status monitoring of a no-tillage planting operation in a dusty environment.Through field trials,the detection accuracy was 91.4%.The seed-clogging fault-alarm accuracy was 96.0%.The entire system remained stable and reliable.Du Ruicheng Gong Bingcai Liu Ningning Wang Chenchen Yang Zidong Ma Mingjian 2013International Journal of Agricultural and Biological Engineering2013,6,3:16

9Effects of Saccharomyces cerevisiae fermentation products on performance and rumen fermentation and microbiota in dairy cows fed a diet containing low quality forage显示文摘Background: A possible option to meet the increased demand of forage for dairy industry is to use the agricultural byproducts, such as corn stover. However, nutritional value of crop residues is low and we have been seeking technologies to improve the value. A feeding trial was performed to evaluate the effects of four levels of Saccharomyces cerevisiae fermentation product(SCFP; Original XP; Diamond V) on lactation performance and rumen fermentation in mid-lactation Holstein dairy cows fed a diet containing low-quality forage. Eighty dairy cows were randomly assigned into one of four treatments: basal diet supplemented with 0, 60, 120, or 180 g/d of SCFP per head mixed with 180, 120, 60, or 0 g of corn meal, respectively. The experiment lasted for 10 wks, with the first 2 weeks for adaptation.Results: Dry matter intake was found to be similar(P > 0.05) among the treatments. There was an increasing trend in milk production(linear, P ≤ 0.10) with the increasing level of SCFP supplementation, with no effects on contents of milk components(P > 0.05). Supplementation of SCFP linearly increased(P < 0.05) the N conversion, without affecting rumen pH and ammonia-N(P > 0.05). Increasing level of SCFP linearly increased(P < 0.05) concentrations of ruminal total volatile fatty acids, acetate, propionate, and butyrate, with no difference in molar proportion of individual acids(P > 0.05). The population of fungi and certain cel ulolytic bacteria(Ruminococcus albus, R. flavefaciens and Fibrobacter succinogenes)increased linearly(P < 0.05) but those of lactate-utilizing(Selenomonas ruminantium and Megasphaera elsdeni) and lactate-producing bacteria(Streptococcus bovis) decreased linearly(P ≤ 0.01) with increasing level of SCFP. The urinary purine derivatives increased linearly(P < 0.05) in response to SCFP supplementation, indicating that SCFP supplementation may benefit for microbial protein synthesis in the rumen.Conclusions: The SCFP supplementation was effective in maintaining milk persistency of mid-lactation cows receiving diets containing low-quality forage. The beneficial effect of SCFP could be attributed to improved rumen function; 1)microbial population shift toward greater rumen fermentation efficiency indicated by higher rumen fungi and cel ulolytic bacteria and lower lactate producing bacteria, and 2) rumen microbial fermentation toward greater supply of energy and protein indicated by greater ruminal VFA concentration and increased N conversion. Effects of SCFP were dose-depended and greater effects being observed with higher levels of supplementation and the effect was more noticeable during the high THI environment.Wen Zhu Zihai Wei Ningning Xu Fan Yang Ilkyu Yoon Yihua Chung Jianxin Liu Jiakun Wang 2017Journal of Animal Science and Biotechnology2017,8,3:13
10Combined obeticholic acid and apoptosis inhibitor treatment alleviates liver fibrosis显示文摘Obeticholic acid(OCA), the first FXR-targeting drug, has been claimed effective in the therapy of liver fibrosis. However, recent clinical trials indicated that OCA might not be effective against liver fibrosis, possibly due to the lower dosage to reduce the incidence of the side-effect of pruritus. Here we propose a combinatory therapeutic strategy of OCA and apoptosis inhibitor for combating against liver fibrosis. CCl4-injured mice, D-galactosamine/LPS(GalN/LPS)-treated mice and cycloheximide/TNFα(CHX/TNFα)-treated HepG2 cells were employed to assess the effects of OCA, or together with IDN-6556, an apoptosis inhibitor. OCA treatment significantly inhibited hepatic stellate cell(HSC)activation/proliferation and prevented fibrosis. Elevated bile acid(BA) levels and hepatocyte apoptosis triggered the activation and proliferation of HSCs. OCA treatment reduced BA levels but could not inhibit hepatocellular apoptosis. An enhanced anti-fibrotic effect was observed when OCA was co-administrated with IDN-6556. Our study demonstrated that OCA inhibits HSCs activation/proliferation partially by regulating BA homeostasis and thereby inhibiting activation of HSCs. The findings in this study suggest that combined use of apoptosis inhibitor and OCA at lower dosage represents a novel therapeutic strategy for liver fibrosis.Jiyu Zhou Ningning Huang Yitong Guo Shuang Cui Chaoliang Ge Qingxian He Xiaojie Pan Guangji Wang Hong Wang Haiping Hao 2019Acta Pharmaceutica Sinica B2019,9,3:13
11New progress and future prospects of CBM exploration and development in China显示文摘Efforts to speed up China's coal bed methane (CBM) exploration developments related to production safety, optimization of energy structures, prevention of energy waste and reduction of greenhouse gas emissions are all of great significance. In order to strengthen CBM exploration and development in China and to encourage increased growth in the CBM industry, we firstly give a general overview of the recent technological innovations and other developments in CBM exploration in the U.S., Canada and other countries. Using this background information as the starting point, we further present observations and analyses of CBM exploration and development, preferential policies, technical support and implications of R&D for CBM development in China. The results show that the problems related to CBM exploration technology development and lack of a complete set of management policies are still the major issues slowing down the growth of domestic CBM industry. Development of resource exploration and technology, R&D and establishment of favorable government policy to support the industry and the creation of a relevant information platform, etc. are finally recommended.Vun Jian Xu Fengyin Liu Lin Zhong Ningning Wu Xiaobin 2012International Journal of Mining Science and Technology2012,22,3:11
12Graft-accelerated virus-induced gene silencing facilitates functional genomics in rose flowers显示文摘Rose has emerged as a model ornamental plant for studies of flower development, senescence, and morphology, as well as the metabolism of floral fragrances and colors.Virus-induced gene silencing(VIGS) has long been used in functional genomics studies of rose by vacuum infiltration of cuttings or seedlings with an Agrobacterium suspension carrying TRV-derived vectors. However, VIGS in rose flowers remains a challenge because of its low efficiency and long time to establish silencing. Here we present a novel and rapid VIGS method that can be used to analyze gene function in rose,called ‘graft-accelerated VIGS', where axil ary sprouts are cut from the rose plant and vacuum infiltrated with Agrobacterium. The inoculated scions are then grafted back onto the plants to flower and silencing phenotypes can be observed within 5 weeks, post-infiltration. Using this new method, we successfully silenced expression of the RhDFR_1, RhA G, and RhNUDX_1 in rose flowers, and affected their color, petal number, as well as fragrance, respectively. This grafting method will facilitate high-throughput functional analysis of genes in rose flowers. Importantly, it may also be applied to other woody species that are not currently amenable to VIGS by conventional leaf or plantlet/seedling infiltration methods.Huijun Yan Shaochuan Shi Nan Ma Xiaoqian Cao Hao Zhang Xianqin qiu Qigang Wang Hongying Jian Ningning Zhou Zhao Zhang Kaixue Tang 2018Journal of Integrative Plant Biology2018,60,1:11
13Cell multiplication, apoptosis and p-Akt protein expression of bone mesenchymal stem cells of rat under hypoxia environment显示文摘Objective: To elucidate whether cell multiplication, apoptosis, glucose intake and p-Akt protein expression of bone Mesenchy-mal Stem Cells(MSCs) of rats is influenced by a hypoxic environment ex vivo. Methods: Passage 3 of bone marrow MSCs takenfrom Wistar rats, were cultured in a culturing chamber with 94%N2, 1%O2, 5%CO2 at 37℃. At different hypoxia time points, 0, 0.5,1, 4 and 8 h, glucose uptake was assayed by using radiation isotope 3H-G, Apoptotic Rate(AR) and dead rate(DR) were analyzedby flow cytometry(FCM) after Annexin V/PI staining, cell multiplication(by MTT methods) and p-Akt protein by immunocyto-chemistry and western blot. Results: Assay for CD29+, CD44+, CD71+, CD34- , Tn T+(after 5-azacytidine agent inducing) andALP+(after bone differentiation agent inducing) suggested these bone-derived cells were MSCs. The 3H-G intaking ratio(CPM/flask value: 157 ±11, 110 ±11, 107 ±13, 103 ±10, 100 ±9 and 98 ±10) of MSCs at different hypoxia time points, significantlydecreased compared to that of normoxia(P < 0.01) and tended to descend slowly with hypoxia time duration, for which there wasno statistical significance(P > 0.05). The AR(0.09 ±2.03%, 12.9 ±1.72%, 13.7 ±2.26%, 13.8 ±3.01%, 14.1 ±2.78% and 14.7 ±4.01% at 0, 0.5, 1, 4 and 8 h, respectively, P < 0.01) and DR (0.04 ±1.79%, 0.93 ±1.85%, 3.11 ±2.14%, 4.09 ±2.36%, 4.72 ±2.05% and 4.91 ±3.72% at 0, 0.5, 1, 4 and 8 h, respectively, P < 0.05) at different hypoxia time points significantly increasedcompared to those time in normoxia; The AR further went up with time (P < 0.05), however there was no statistical significance(P > 0.05) for the DR. Optical absorption value of MTT methods at different hypoxia time points significantly decreased com-pared to those with a corresponding normoxia time (P < 0.01) and degraded with time (in an hypoxic environment - P < 0.01).IOD of p-Akt protein of MSCs at different hypoxia time points significantly increased (0.367 ±0.031, 0.556 ±0.023, 0.579 ±0.013, 0.660 ±0.024, 0.685 ±0.039 and 0.685 ±0.011, respectively) compared to their equivalents in normoxia (P<0.05), how-ever, there was no statistical significance (P > 0.05) for different hypoxia time points. Hypoxia may result in ultramicrostructurechanges, such as defluvium of Microvilli, apoptotic body, 'margination'and so on and are further aggravated with hypoxia timestretching. Conclusion: Hypoxia may lead to a depression of MSCs intaking glucose, creep of cell multiplication, upregulation ofp-Akt protein and apoptosis of MSCs ex vivo.Hongliang Kong Ningning Liu Xin Huo Bo Wang Haipeng Zhang Mingyu Gao Guoxian Qi 2007Journal of Nanjing Medical University2007,21,4:10
14Studies on the overexpression of the soybean GmNHX1 in Lotus corniculatus: The reduced Na^+ level is the basis of the increased salt tolerance显示文摘The full length cDNA coding for a novel vacuolar Na+/H+ antiporter (GmNHX1) was cloned from soybean and determined to consist of 2591 bp with a 5′-untranslated region of 464 bp, an open reading frame (ORF) of 1641 bp, and a 3′-untrans- lated region of 486 bp. The deduced protein se- quence contains 546 aa with the typical characters of the vacuolar Na+/H+ antiporters, and shares high similarity with that of AtNHX1, OsNHX1 and AgNHX1. The soybean genome showed a single copy of the GmNHX1 gene. Northern blot analysis demonstrated that the expression of the GmNHX1 was tissue-spe- cific, increased by ABA treatment, NaCl, KCl, LiCl and dehydration stress, and lower in leaves but higher in roots and hypocotyls of salt-tolerant than salt-sensitive cultivars. The GmNHX1 was overex- pressed under the control of a tandem cauliflower mosaic virus (CaMV) 35S promoter in the model le- guminous plant Lotus corniculatus L. and conferred salt-tolerance of the transgenic plants. Measure- ments of Na+ and K+ contents in both roots and shoots demonstrated that the plantlets of GmNHX1- overexpressing lines had lower Na+ and K+ content, and higher K+/Na+ ratio than the controlled lines that were transformed with the empty vector, which indi- cates that the salt-tolerance conferred by GmNHX1 is closely related with decreased accumulation of Na+ in the transgenic plants.SUN Yanxiang WANG Dan BAI Yanling WANG Ningning WANG Yong 2006Chinese Science Bulletin2006,51,11:10
15A Discussion on the Origin of Shale Reservoir Inter-Laminar Fractures in the Shahejie Formation of Paleogene, Dongying Depression显示文摘This paper was conducted on the shale reservoir in the Dongying depression in the Shahejie Formation of Paleogene. Based on detailed core description, rock thin sections, argon ion polishing, scanning electron microscopy(SEM) analysis, CT scanning and carbon-oxygen isotopic test, the formation mechanism of the inter-laminar fractures(or seams) and their development conditions were discussed by comprehensive analysis of the diagenetic evolution features and the reservoir space evolution characteristics. The results show that the laminated composite pattern in Dongying depression was dominated by vertical distribution of laminated calcite and clay minerals. Contrasted to the traditional understanding, development degree of inter-laminar fractures was much lower. Pure fluid between layers cannot exist without framework minerals, and the pre-existing well connected pore or horizontal overpressure micro seam was favorable paths of fluid migration. From the points of inter-laminar fractures origin mechanism and its evolution, the so called seams, were much more complex than traditional understanding that hydrocarbon generation raised the pore pressure and led to the parallel microfractures. But the inter-laminar fractures had little relationship with that whether the lamination was developed or bedding boundary was clear or not. In fact, the shale reservoir inter-laminar fractures were not rigorous fracture. They were controlled by pre-existing inter-granular pore(or seam) or dissolved pore, which distributed along carbonate laminae boundary and were connected by later super pressure, dissolution and the seepage force. And the development conditions were burial depth(bigger than 3 000 m) and the Ro value(>0.6%). Discussion on its origin and evolution has important petroleum geological significance on optimizing reservoir segment and favorable target areas selection.Huimin Liu Shun Zhang Guoqi Song Shoupeng Zhang Xuefeng Hao Zhonghuai Xie Ningning Xu Peng Liu 2017Journal of Earth Science2017,28,6:10
16NEAT1/miR-140-3p/MAPK1 mediates the viability and survival of coronary endothelial cells and affects coronary atherosclerotic heart disease显示文摘Studies have shown that long non-coding RNAs(lncRNA)play critical roles in coronary atherosclerotic heart disease(CAD).However,the function of lncRNA nuclear enriched abundant transcript 1(NEAT1)in CAD is unclear.In this study,we aimed to investigate the functions of lncRNA NEAT1 in CAD.RTPCR and western blot analysis were carried out to examine the expressions of related RNAs.Colony formation assay,cell proliferation assay,apoptosis assay,and dual-luc讦erase reporter assay were con ducted to investigate the abilities of colony migration,cell proliferatio n,apoptosis,and targeting.The results showed that NEAT1 was up-regulated in CAD blood samples and in human coronary endothelial cells(HCAECs).Transfection of pcNEATI sign讦icantly inhibited the survival rate of HCAECs and induced apoptosis of HCAECs.MiR-140-3p was down-regulated in HCAECs.NEAT1 directly targeted miR-140-3p,and the expression of miR-140-3p was inversely correlated with the expression of NEAT1 in CAD patients.In addition,co-transfection of NEAT1 with miR-140-3p mimic reversed the effect of pcNEATI on cell viability and apoptosis,mitogenactivated protein kinase 1(MAPK1)was proved to be a target gene of miR-140-3p,and the miR-140-3p mimic was shown to reduce the expression of MAPK1 in HCAECs.pcNEATI sigrdficantly increased the expression level of MAPK1,while shNEATI significantly reduced the expression level of MAPK1.Our results revealed that lncRNA NEAT1 increased cell viability and inhibited CAD cell apoptosis possibly by activating the miR-140-3p/MAPK1 pathway,and lncRNA NEAT1 might serve as a potential therapeutic target for CAD.Hui Zhang Ningning Ji Xinyan Gong Shimao Ni Yu Wang 2020Acta Biochimica et Biophysica Sinica2020,52,9:9
17Effects of AMF on soil enzyme activity and carbon sequestration capacity in reclaimed mine soil显示文摘A series of pot experiments and field trials were carried out to evaluate the effects of arbuscular mycorrhizal fungi(AMF) on activities of soil enzymes and carbon sequestration capacity in reclaimed mine soil.A complex substrate of coal gangue,fly ash and sludge was used as reclaimed mine soil,and ryegrass was planted with AMF inoculation to construct a plant-complex substrate-microbe ecological restoration system.The changes to the soil organic carbon(SOC),activities of soil enzymes and glomalin-related soil protein(GRSP) were measured and the effects of AMF on activities of soil enzymes and carbon sequestration capacity in reclaimed mine soil were analyzed.The results show that the contents of GRSP(total glomalin(TG) and easily extractable glomalin(EEG)),SOC and activities of enzymes increased,and the increments were higher in the AMF inoculation treated plant-complex substrate-microbe ecological restoration systems than those with no AMF inoculated treatments after 12 months of ryegrass growth.TG,EEG and soil enzyme activity have a significant positive correlation,and the correlative coefficient was 0.427-0.573;SOC and TG,EEG have a significant positive correlation(p < 0.01),indicating that AMF plays an important role in carbon sequestration of reclaimed mine soils.Qian Kuimei Wang Liping Yin Ningning 2012International Journal of Mining Science and Technology2012,22,4:9
18Inheritance of Perpetual Blooming in Rosa chinensis ‘Old Blush'显示文摘Perpetual blooming is one of the most important biological and economical traits in modern rose, while the genetic basis underlining the control of this trait is poorly investigated. With an aim in dissecting the genetic determinism of perpetual blooming, we developed six rose populations(OB, W, F1, F2, BC1 OB and BC1W) derived from a WOB population [interspecific diploid hybridization between Rosa chinensis ‘Old Blush'(OB) and R. wichuriana ‘Basye's Thornless'(W)]. Perpetual blooming is absent both in a F1 population with 296 individuals and a BC1 W population(W as the backcross parent) with 150 individuals. However, the perpetual blooming trait showed a typical 3︰1 segregation in a backcross population BC1 OB with OB as the backcross parent. In this population with 300 individuals, 83 plants had the perpetual blooming phenotype while the other 217 featured non-perpetual blooming, indicating that the perpetual blooming trait is very likely controlled by two recessive genes in R. chinensis(rpb1 and rpb2). These genetic data suggest that the inheritance of rose perpetual blooming may be controlled by a complex mechanism.LI Shubin ZHOU Ningning ZHOU Qing YAN Huijun JIAN Hongying WANG Qigang CHEN Min QIU Xianqin ZHANG Hao WANG Shufang LI Shufa TANG Kaixue 2015Horticultural Plant Journal2015,1,2:9
19Study of simulation experiments on the TSR system and its effect on the natural gas destruction显示文摘The TSR process may be one of the reasons to result in the natural gas destruction in deep carbonate reservoirs. The work on this field has been the subject of much research in recent years. In this paper, thermal simulation experiments on the reaction of CH4-CaSO4 were carried out using autoclave at high temperature and high pressure. The products were charac-terized by some advanced analytical methods. The thermodynamics and kinetics were discussed and the reaction mechanism was investigated tentatively. It is found that the reaction can pro-ceed spontaneously to produce H2S, H2O and CaCO3 as the main products at the temperature range of 550―700℃ . The activation energy and geological reaction rate calculated from the ki-netic model can be compared with those from previous work. The results obtained in this paper can provide important information on the explanation of geochemical depth limit for natural gas and on the exploration of gas reservoirs.YUE Changtao LI Shuyuan DING Kangle ZHONG Ningning 2005Science China Earth Sciences2005,48,8:8
20Chemical kinetics study of hydrocarbon regeneration from organic matter in carbonate source rocks and its significance显示文摘In the comparison research of hydrocarbon regeneration, a low maturity carbonate source rock is heated to different temperatures in a gold tube to obtain a series of samples with different maturities. Then, the heated samples, before and after extraction, are subjected to Rock-Eval pyrolysis through a thermal simulation of hydrocarbon regeneration in order to inspect pyrolysis characteristics and probe into the characteristics of the chemical kinetics of each sample. The results indicate that, whether hy- drocarbon regeneration peak is delayed or advanced, the potential of hydrocarbon regeneration is closely related to the expulsion amount and breakdown maturity of primary hydrocarbon generation. After extraction, the average activation energy of artificially maturated samples increases with the in- creasing maturity, but the chemical kinetic properties of un-extracted samples decrease. The calibrated chemical kinetic models that describe extracted and un-extracted samples are applied to the Bohai Bay and the Songliao Basin, and the results indicate that the combination of the two models can explain some contradictory conclusions previously reported. These results also facilitate the quantitative evaluation of the amount of hydrocarbon regeneration by the chemical kinetic method.LU ShuangFang ZHONG NingNing XUE HaiTao PAN ChangChun LI JiJun LI HongTao 2007Science China Earth Sciences2007,50,4:8
