| 2 | Risk factors and long-term health consequences of macrosomia:a prospective study in Jiangsu Province,China显示文摘We sought to determine risk factors associated with fetal macrosomia and to explore the long-term consequence of infant macrosomia at the age of 7 years.A prospective population based cohort study was designed to examine the associations between maternal and perinatal characteristics and the risk of macrosomia.A nested case-control study was conducted to explore the long-term health consequence of infant macrosomia.The mean maternal age of the macrosomia group was 24.74±3.32 years,which is slightly older than that in the control group(24.35±3.14 years,P = 0.000).The mean maternal body mass index(BMI) at early pregnancy was 22.75±2.81 kg/m 2,which was also higher than that in the control group(21.76±2.59 kg/m 2,P = 0.000).About 64.6% of macrosomic neonates were males,compared with 51.0% in the control group(P = 0.000).Compared with women with normal weight(BMI:18.5-23.9 kg/m 2),women who were overweight(BMI:24-27.9 kg/m 2) or obese(BMI ≥ 28 kg/m 2),respectively,had a 1.69-fold(P = 0.000) and a 1.49-fold(P = 0.000) increased risks of having a neonate with macrosomia,while light weight(BMI<18.5 kg/m 2) women had an approximately 50% reduction of the risk.Furthermore,macrosomia infant had a 1.52-fold and 1.50-fold risk,respectively,of developing overweight or obesity at the age of 7 years(P = 0.001 and P = 0.000).Older maternal age,higher maternal BMI at early pregnancy and male gender were independent risk factors of macrosomia.Macrosomic infant was associated with an increased predisposition to develop overweight or obesity at the beginning of their childhood. | Shouyong Gu Xiaofei An Liang Fang Xiaomin Zhang Chunyan Zhang Jingling Wang Qilan Liu Yanfang Zhang Yongyue Wei Zhibin Hu Feng Chen Hongbing Shen | 2012 | The Journal of Biomedical Research2012,26,4: | 14 |
| 3 | Method for Evaluating the Degrees of Land Use Sustainability of Mountainous County and its Application in Yunnan Province,China显示文摘The evaluation of sustainable land use is the key issue in the field of studying the sustainable land utilization. In general analysis, the sustainable land use is evaluated respectively from its ecological sustainability, economic sustainability and social sustainability in China and other countries in recent years. Although this evaluation is an important work, it seems insufficient and hard to comprehensively reflect the whole degree of land use sustainability. Thus, to make up this deficiency, this paper brings forward the evaluation indexes, which make it possible to quantitatively reflect the whole degree of land use sustainability, namely, the concept of 'degrees of overall land use sustainability' (DOS), and research and development of the method of measurement and calculation in DOS. Taking the evaluation of the degree of land use sustainability in county regions of Yunnan Province as the actual example for analysis, results are basically as follows:1) The degree of land use sustainability (DOS) is the ration index to organically and systematically integrate the degree of ecological friendliness (DEF), the degree of economic viability (DEV) and the degree of social acceptability (DSA), able to comprehensively reflect the whole sustainability degree of regional land use. 2) Based on the value of DOS, the grading system and standard for the sustainability of land use may be established and totally divided into five grades, namely, the high-degree sustainability, middle-degree sustainability, low-degree sustainability, conditional sustainability and non-sustainability. Meanwhile, the standard for distinguishing sustainability grades has also been confirmed so as to determine the nature of sustainability degrees in different grades. This makes the possibility for the combination of nature determination with ration in research result and provides with the scientific guideline and decision-making gist for better implementation of sustainable land use strategy.3) The practice in evaluation of sustainability degree in county regional land use in Yunnan shows that the value of the degree of land use sustainability (DOS) of whole Yunnan Province is only 58.39, belonging to the grade of low-degree sustainability. Two thirds of counties in the whole province represent the grade of 'conditional sustainability' and 'non-sustainability' in the sustainability of land use. Among these counties, 11.11 % shows 'non- sustainability'. The lowest degree of land use sustainability appears especially in the middle plateau mountain region of Northeast Yunnan, where the value of DOS in most counties (districts) is below 40 %, belonging to the grade of 'non-sustainability'. The sustainability degree in the karst mountainous region in lower-middle plateau mountain region in Southeast Yunnan is generally low and the value of sustainability degree (DOS) in most of the counties (cities and districts) is below 55. The value of sustainability degree (DOS) in most of the counties (cities and districts) in the north, west, northwest and southwest parts of Yunnan is below 55. This article also analyzes the reasons of low degree of sustainability in land use in Yunnan and puts forward the countermeasures to increase the degree of sustainability in land use in the whole province. | YANG Zisheng LIU Yansui TAO Wenxing XU Jingling ZHAO Qiaogui | 2008 | Journal of Mountain Science2008,5,2: | 10 |
| 4 | Geophysical methods for the study of sedimentary cycles显示文摘We present the wavelet depth-frequency analysis and variable-scale frequency cycle analysis methods to study sedimentary cycles.The spectrum analysis,variable-scale frequency cycle analysis, and wavelet depth-frequency analysis methods are mainly discussed to distinguish sedimentary cycles of different levels.The spectrum analysis method established the relationship between the spectrum characteristics and the thickness and number of sedimentary cycles.Both the variable-scale frequency cycle analysis and the wavelet depth-frequency analysis are based on the wavelet transform.The variable-scale frequency cycle analysis is used to obtain the relationship between the periodic changes of frequency in different scales and sedimentary cycles,and the wavelet depth-frequency analysis is used to obtain the relationship between migration changes of frequency energy clusters and sedimentary cycles. We designed a software system to process actual logging data from the Changqing Oilfield to analyze the sedimentary cycles,which verified the effectiveness of the three methods,and good results were obtained. | Xu Jingling Liu Luofu Wang Guiwen Shen Jinsong Zhang Chunhua | 2009 | Petroleum Science2009,6,3: | 10 |
| 5 | Pollution characteristics and ecological risk of polycyclic aromatic hydrocarbons (PAHs) in surface sediments of the southern part of the Haihe River system in China显示文摘The southern part of the Haihe River system, the largest river system in the Haihe River Basin, is important to maintain a healthy ecosystem and safe drinking water as well as for the economic development of China. To assess the effect of rapid industrialization and urbanization on the pattern of polycyclic aromatic hydrocarbon (PAH) contamination, the PAH pollution characteristics of the southern part of the Haihe River system was investigated. Sixteen PAHs in surface sediments samples collected from 24 sites covering the southern part of the Haihe River system from the upstream to the estuaries were detected and analyzed. The total PAH concentration ranged from 258.77 to 11296.66 ng/g dry weight. On average, 2-, 3-, 4-, 5and 6-ring PAHs comprised 25.32%, 27.22%, 22.62%, 14.89% and 9.96% of the total PAHs, respectively. Sites with high concentrations were concentrated in the Fuhe River, Fuyang River and Wei River, which are located near cities. A risk quotient (RQ) was used to assess the ecological risk of PAHs. The mean values of the RQ(MPCs) of individual PAHs were lower than 1.00, except for those of naphthalene (2.00) and pyrene (1.67). The RQPAHs calculated for the samples indicated that the Xidayang reservoir and the estuary of the Ziya River were determined to be at a low risk level, while Baoding City, Handan City and Aixinzhuang were determined to be at a high risk level. | LIU Feng LIU JingLing CHEN QiuYing WANG BinBin CAO ZhiGuo | 2013 | Chinese Science Bulletin2013,58,27: | 9 |
| 6 | Estimation methods of eco-environmental water requirements: Case study显示文摘Supplying water to the ecological environment with certain quantity and quality is significant for the protection of diversity and the realization of sustainable development. The conception and connotation of eco-environmental water requirements, including the definition of the conception, the composition and characteristics of eco-environmental water requirements, are evaluated in this paper. The classification and estimation methods of eco-environmental water requirements are then proposed. On the basis of the study on the Huang-Huai-Hai Area, the present water use, the minimum and suitable water requirement are estimated and the cor-responding water shortage is also calculated. According to the interrelated programs, the eco-environmental water requirements in the coming years (2010, 2030, 2050) are estimated. The result indicates that the minimum and suitable eco-environmental water requirements fluc-tuate with the differences of function setting and the referential standard of water resources, and so as the water shortage. Moreover, the study indicates that the minimum eco-environmental water requirement of the study area ranges from 2.84×1010m3 to 1.02×1011m3, the suitable water requirement ranges from 6.45×1010m3 to 1.78×1011m3, the water shortage ranges from 9.1×109m3 to 2.16×1010m3 under the minimum water requirement, and it is from 3.07×1010m3 to 7.53×1010m3 under the suitable water requirement. According to the different values of the water shortage, the water priority can be allocated. The ranges of the eco-environmental water re-quirements in the three coming years (2010, 2030, 2050) are 4.49×1010m3?1.73×1011m3, 5.99×10m3?2.09×1011m3, and 7.44×1010m3?2.52×1011m3, respectively. | YANG Zhifeng1,2, CUI Baoshan1 & LIU Jingling 1.

| 7 | Cell-free plasma hypermethylated CASZ1, CDH13 and ING2 are promising biomarkers of esophageal cancer显示文摘Identifying sensitive and specific biomarkers for early detection of cancer is immensely imperative for early diagnosis and treatment and better clinical outcome of cancer patients. This study aimed to construct a specific DNA methylation pattern of cancer suppressor genes and explore the feasibility of applying cell-free DNA based methylation as a biomarker for early diagnosis of esophageal squamous cell carcinoma(ESCC). We recruited early stage ESCC patients from Yangzhong County, China. The Illumina Infinium 450 K Methylation BeadChip was used to construct a genome-wide DNA methylation profile. Then, differentiated genes were selected for the validation study using the Sequenom MassARRAY platform. The frequency of methylation was compared between cancer tissues, matched cell-free DNAs and normal controls. The specific methylation profiles were constructed, and the sensitivity and specificity were calculated. Seven CG sites in three genes CASZ1, CDH13 and ING2 were significantly hypermethylated in ESCC as compared with normal controls. A significant correlation was found between the methylation of DNA extracted from cancer tissues and matched plasma cell-free DNA, either for individual CG site or for cumulative methylation analysis. The sensitivity and specificity reached 100% at an appropriate cut-point using these specific methylation biomarkers. This study revealed that aberrant DNA methylation is a promising biomarker for molecular diagnosis of esophageal cancer. Hypermethylation of CASZ1,CDH13 and ING2 detected in plasma cell-free DNA can be applied as a potential noninvasive biomarker for diagnosis of esophageal cancer. | Huanqiang Wang Congying Yang Siyuan Wang Tian Wang Jingling Han Kai Wei Fucun Liu Jida Xu Xianzhen Peng Jianming Wang | 2018 | The Journal of Biomedical Research2018,32,6: | 6 |
| 8 | The Distribution of Dissolved Aluminum in the Yellow and East China Seas显示文摘Water samples containing dissolved aluminum were collected from the Yellow and East China Seas in Octo- ber-November 2000. The average concentrations of dissolved Al in the Yellow Sea (YS) and East China Sea (ECS) were 0.042 and 0.056 μmolL-1, respectively. The concentration of dissolved aluminum decreased gradually across the continental shelf. The lower concentrations appeared in the YS cold water center and in the bottom layer at the shelf edge of the ECS, where they were 0.016 and 0.011 μmolL-1, respectively. The distribution of dissolved Al was controlled by physical mixing processes rather than biological up- take processes. The impact of different water masses along the PN transect was calculated based on the mass balance model. The results show that the impact of the Changjiang River was mainly concentrated on the coastal area and the top thermocline water on the ECS shelf, where the impact percentage decreased from 12.6% to 1.1% in the surface water, while the contribution of the Ku- roshio water was dominant on the ECS shelf in this survey, increasing from 77.6% to 97.8% along the PN transect from the Changjiang River Estuary to the Ryukyu Islands. It is concluded that aluminum can serve as a proper tracer for studying the impact of Changjiang terrestrial matter on the ECS shelf water. | LI Jianbing REN Jingling ZHANG Jing LIU Sumei | 2008 | Journal of Ocean University of China2008,7,1: | 5 |
| 9 | The biogeochemical behavior of dissolved aluminum in the southern Yellow Sea:Influence of the spring phytoplankton bloom显示文摘Many recent studies have investigated the nutrient-type profiles of dissolved aluminum(Al) in the ocean.Significant scavenging of dissolved Al can occur during phytoplankton blooms,but the mechanism remains unclear.The distribution of dissolved Al in the southern Yellow Sea(SYS) was investigated in winter and spring 2009.Following measurements at grid stations during the spring sampling cruise,two drifting anchor surveys of more than 100 h were conducted to trace the variation of dissolved Al concentration during the spring phytoplankton bloom(SPB).The concentration of dissolved Al in the SYS decreased from 40 nmol/L in February to 30 nmol/L in March and 10-20 nmol/L in April,while the concentration of Chl a increased from < 2 μg/L in March to > 4 μg/L in April.The concentration of dissolved Al in the SYS decreased significantly with the development of the phytoplankton bloom,which indicated biological scavenging of dissolved Al from water column.The proportion of dissolved Al scavenged from water column by different phytoplankton species differed at the two drifting stations,with greater removal efficiency demonstrated by diatoms than dinoflagellates.Phytoplankton samples collected from the Chl a maximum layer were washed with trace metal clean reagent(oxalate-EDTA-citrate,abbreviate as oxalate solution,Tovar-Sanchez et al.,2003) to enable the surface-scavenged(extracellular) and intracellular Al pools associated with phytoplankton to be differentiated.Thirty-nine to ninetysix percent of the total Al was found to be existed in the interior pools,which indicated that biological absorption was the important way to scavenge dissolved Al during phytoplankton blooms in the SYS. | LI FaMing REN JingLing YAN Li LIU SuMei LIU ChengGang ZHOU Feng ZHANG Jing | 2013 | Chinese Science Bulletin2013,58,2: | 4 |
| 10 | Cycling of phosphorus in the Jiaozhou Bay显示文摘Dissolved inorganic phosphorus (DIP ),dissolved organic phosphorus (DOP ),particulate inorganic phosphorus (P IP ) and particulate organic phosphorus (P OP ) in the Jiaozhou Bay (JZB) and its adjacent major rivers were analyzed during 2001–2003.DIP was the major form of dissolved phosphorus in JZB,representing 62%–83% of the total dissolved phosphorus (T DP ),and the P IP concentration generally exceeded the P OP concentration.The concentrations of phosphorus were higher in the north than in the south of the bay,which were related to the fluvial input and water exchange rate.The dissolved phosphorus concentrations were higher in the autumn and spring than in the summer,while the seasonal variation of particulate phosphorus showed opposite pattern.The distribution of phosphorus is mainly affected by the growth of phytoplankton,desorption/adsorption of DIP from and to particulates,and anthropogenic activities.A preliminary phosphorus budget was established.In JZB,riverine input and water exchange flow between JZB and the Huanghai (Yellow) Sea are the major sources of phosphorus,followed by industrial and domestic waste transport,and then atmospheric deposition.Phosphorus burial efficiency is estimated to be 91%.About 52.2 × 10 6 mol/a of phosphorus were assimilated by phytoplankton,of which about 68% was recycled in the water column and sediment. | Q1 Xiaohong LIU Sumei ZHANG Jing REN Jingling ZHANG Guiling | 2011 | Acta Oceanologica Sinica2011,30,2: | 4 |
| 11 | Study of sedimentary sequence cycles by well-seismic calibration显示文摘In order to solve the problems of the fine division of sedimentary sequence cycles and their change in two-dimensional space as well as lateral extension contrast, we developed a method of wavelet depth-frequency analysis. The single signal and composite signal of different Milankovitch cycles are obtained by numerical simulation. The simulated composite signal can be separated into single signals of a single frequency cycle. We also develop a well-seismic calibration insertion technology which helps to realize the calibration from the spectrum characteristics of a single well to the seismic profile. And then we determine the change and distribution characteristics of spectrum cycles in the two-dimensional space. It points out the direction in determining the variations of the regional sedimentary sequence cycles, underground strata structure and the contact relationship. | Xu Jingling Liu Luofu Wang Guiwen Zou Changchun Lai Jin | 2013 | Petroleum Science2013,10,1: | 4 |
| 12 | Neuritin promotes angiogenesis through inhibition of DLL4/Notch signaling pathway显示文摘Neuritin is a member of the neurotrophic factor family,which plays an important role in the promotion and development of the nervous system.Neuritin is also involved in angiogenesis.Neuritin was recently found to be a negative regulatory factor of the Notch 1 signaling pathway.Notch signaling pathway is known as a regulatory pathway of angiogenesis.Thus,neuritin may play a role in angiogenesis through the Notch signaling pathway.In the present study,we investigated the expressions of neuritin and Notch signaling pathway factors in the pulmonary vascular tissue.The results showed that neuritin expression was increased in the paraneoplastic vascular tissue and decreased in the lung cancer vascular tissue.The neuritin expression was increased with the increase of vascular tissue density,and a negative correlation between neuritin expression and delta-like ligand 4(DLL4)was identified in vascular tissues of lung cancer.Overexpression of neuritin in human umbilical vein endothelial cells(HUVECs)inhibited the expressions of Notch signaling pathway-associated factors,including DLL4,NICD,and Hes-1,and promoted the migration and tubular formation of HUVECs.In conclusion,our results indicated that neuritin is involved in angiogenesis and may play a role in angiogenesis through the Notch signaling pathway.This study provides a theoretical basis for clinical anti-angiogenesis therapy. | Li Yang Xuhui Wang Jiawei Sun Chunyan Liu Guoxiang Li Jingling Zhu Jin Huang | 2021 | Acta Biochimica et Biophysica Sinica2021,53,6: | 4 |
| 13 | Seasonal variations of particulate silicon in the Changjiang (Yangtze River) Estuary and its adjacent area显示文摘Temporal and spatial distribution of biogenic (BSi) and lithogenic (LSi) silica were studied in the Changjiang (Yangtze River) Estuary and its adjacent area. The annual average BSi and LSi concentrations were (1.71 ± 1.79) μmol/L and (0.56 ± 1.41) mmol/L, respectively. Both BSi and LSi were high in the inshore areas, where they received terrigenous discharge from the Changjiang, and decreased towards the offshore region. BSi and LSi were most abundant at the near bottom layer due to the high sedimentation rates and resuspension of sediment. Diatom blooms occurred in summer with high Chl a concentration in the surface layer, which induced that BSi in the surface layer during summer was obviously higher than that in the surface layer of other seasons. LSi concentration was maximal in autumn and spring and minimum in summer, associated with the seasonal variation of SPM values. Drifting investigation and mesocosm experiments were conducted during dinoflagellate bloom, aiming to understand the effect of nutrients on BSi by changing the phytoplankton composition. The results show that the low dissolved inorganic phosphorus concentration and high molar ratio of N/P (dissolved inorganic nitrogen vs. dissolved inorganic phosphorus), were the important factors for decreasing diatom biomass in the study area, and it would subsequently decrease the BSi concentration in aquatic ecosystem. | CAO Lu LIU Sumei REN Jingling | 2013 | Acta Oceanologica Sinica2013,32,4: | 3 |
| 14 | Grain Composition and Erosive Equilibrium of Debris Flows显示文摘Debris flows consist of grains of various sizes ranging from 10^(-6) m ~1 m. Field observations in the Jiangjia Gully (JJG) and other sites throughout China indicate that the grain size distribution of sediment in debris flows can be characterized by an exponential function fit to the cumulative distribution. The exponent value for the function varies by location and may be useful in distinguishing between debris flows from different valleys. For example, minimum values and ranges of the exponent are associated with the high frequency of debris flows in the JJG. Furthermore, the distribution presents piecewise fractality (i.e. scaling laws hold in various ranges of the grain size) and we propose that the fractal structure determines the matrix and that the fractal dimension plays a crucial role in material exchange between a debris flow and the substrate it flows over. Finally, the empirical data support an exponential relation between grain composition and non-dimensional shear stress for the critical state of the channel. Overall we propose a material-determinism approach to studying debris flows which contrasts with the enviro-determinism that has dominated much recent work in this field. | LI Yong LIU Jingling CHEN Xiaoqing WEI Fangqiang | 2007 | Journal of Mountain Science2007,4,1: | 3 |
| 15 | Characteristic analysis of ecosystem service value of water system in Taiyuan urban district based on LUCC显示文摘Changes in the land use and ecosystem service value of the 600 m buffer zone of Jinyang Lake and the 1000 m riparian zone of the Fenhe River in the Taiyuan urban district in China,were studied using satellite image data collected in June 2006 and June 2013.According to the ecosystem services assessment system based on expert knowledge,the ecosystem service value(ESV)per unit area was determined for various land-use types and the value of the water system and its buffer regions in the Taiyuan urban district were determined.And then the relationship between LUCC(Land Use/Cover Change)and ESV was discussed.Moreover,the accuracy and validity of the results was analyzed.The results showed that:(1)the areas of green vegetation and water bodies of Jinyang Lake and its buffer region decreased by 24.96%and 3.22%,respectively,between June 2006 and June 2013,whereas the areas of farmland and built-up land increased by 15.81%and 12.37%,respectively.At Jinyang Lake,the degree of dynamic change for green vegetation,water bodies,farmland,built-up land,and unused land was−0.13,−0.02,0.17,0.09,and−0.05,respectively.In the Fenhe River’s buffer region,the areas of green vegetation,farmland and unused land decreased by 1.36%,6.36%and 0.3%,respectively,but those of built-up land and water bodies increased by 1.41%and 6.61%,respectively.Their degree of dynamic change was−0.03,−0.02,−0.04,0.01 and 0.32,respectively;(2)In 2006,the landscape fragmentation indices(LFI)of Jinyang Lake buffer of 0-200 m zone were greater than 2,but those of 200-600 m buffer zone were less than 0.3,the water-body index not included.However,in 2013,the landscape fragmentation indices of green vegetation and water bodies of 0-600 m buffer zone were both high,meaning that the land-use pattern had improved.The fragmentation index of green vegetation of the 0-200 m buffer increased from 0.1(the minimum for the year)to 1.7(the maximum for the year)during the seven years of this study along the Fenhe River.The fragmentation index of built-up land increased from 0.007 to 0.01 in the 200-500 m buffer and from 0.007 to 0.06 in the 500-1000 m buffer.(3)The total ecosystem service value of Jinyang Lake and its buffer region decreased by 22.673%,whereas during the same period,that of the Fenhe River and its buffer region increased by 41.345%.The total ecosystem service value of the water bodies and their buffer regions in the Taiyuan urban area increased by 13.725%overall.(4)The change rate of the ecosystem service value of the 0-600 m buffer region decreased by 1.579%at Jinyang Lake,while that of the 0-1000 m buffer region increased 5.079%at the Fenhe River over the seven years. | Liu Ping Zheng Xiuqing Chen Junfeng Zhang Qing Li Jingling Wu Bo | 2016 | International Journal of Agricultural and Biological Engineering2016,9,1: | 3 |
| 16 | Ecosystem health assessment of urban rivers and lakes-Case study of “the six lakes”in Beijing,China显示文摘The assessment of the ecosystem health of urban rivers and lakes is the scientific basis for their management and ecological restoration.This study developed a three-level indicator system for its assessment.The results indicated that:Zhonghai and Nanhai are in the state of transition from unhealthy to critical state and all the other lakes are in unhealthy states.Water environmental quality,structure and function of the aquatic ecosystem,and the structure of waterfront areas were the constraints.Nanhai was ranked as poor and the others were all ranked as very poor.However,the ecological environment of Zhonghai and Nanhai were better than the others,the sums of the degree of membership to the healthy state and critical state were all close to 0.6.and the restorations of these lakes were moderate.The sums of the degree of membership to the healthy state and critical state of the other lakes were under 0.3,as it was difficult to restore these lakes.Some suggestions on scientific management and ecological restoration of the six lakes were proposed:①To control non-point pollution and to improve the water quality of six lakes and the water entering into these lakes;②To improve the hydrological conditions of six lakes;③To rehabilitate the aquatic ecosystem and waterfront areas. | Fengling ZHANG Jingling LIU Zhifeng YANG Yongli LI | 2008 | Frontiers of Environmental Science & Engineering2008,2,2: | 3 |
| 17 | 3D-printed dermis-specific extracellular matrix mitigates scar contraction via inducing early angiogenesis and macrophage M2 polarization显示文摘Scar contraction frequently happens in patients with deep burn injuries.Hitherto,porcine dermal extracellular matrix(dECM)has supplied microenvironments that assist in wound healing but fail to inhibit scar contraction.To overcome this drawback,we integrate dECM into three-dimensional(3D)-printed dermal analogues(PDA)to prevent scar contraction.We have developed thermally gelled,non-rheologically modified dECM powder(dECMp)inks and successfully transformed them into PDA that was endowed with a micron-scale spatial structure.The optimal crosslinked PDA exhibited desired structure,good mechanical properties as well as excellent biocompatibility.Moreover,in vivo experiments demonstrated that PDA could significantly reduced scar contraction and improved cosmetic upshots of split thickness skin grafts(STSG)than the commercially available dermal templates and STSG along.The PDA has also induced an early,intense neovascularization,and evoked a type-2-like immune response.PDA’s superior beneficial effects may attribute to their desired porous structure,the well-balanced physicochemical properties,and the preserved dermis-specific ECM cues,which collectively modulated the expression of genes such as Wnt11,ATF3,and IL1β,and influenced the crucial endogenous signalling pathways.The findings of this study suggest that PDA is a clinical translatable material that possess high potential in reducing scar contraction. | Lei Chen Zhiyong Li Yongtai Zheng Fei Zhou Jingling Zhao Qiyi Zhai Zhaoqiang Zhang Tianrun Liu Yongming Chen Shaohai Qi | 2022 | Bioactive Materials2022,7,4: | 3 |
| 18 | Distribution of Dissolved Inorganic Arsenic and Its Seasonal Variations in the Coastal Area of the East China Sea显示文摘Water samples were collected in the coastal area of the Changjiang Estuary on four cruises from August 2002 to May 2003. The seasonal variations of dissolved inorganic arsenic (DIAs) distributions were analyzed. The results showed that the distributions of DIAs were mainly influenced by the terrestrial input and the intrusion of the Kuroshio Subsurface Water (KSSW). The concentration of the total dissolved inorganic arsenic (TDIAs) decreased consecutively from winter to summer, while it increased in autumn. The distributions of TDIAs showed some relationships with salinity and suspended particulate matter (SPM). The relationships between DIAs speciation (including arsenite [As(Ⅲ)] and arsenate [As(Ⅴ)]), biological activity and the availabilities of the phosphate were investigated in the study area for the cruise August 2002. The ratio of As (Ⅲ)/TDIAs increased with the decrease of phosphate concentrations. In the bottom water, the As(Ⅲ)/TDIAs ratio decreased with the increasing of N/P. The concentration of TDIAs decreased 28.7% approximately after the occurrence of harmful algal blooms (HAB) because of the uptake of arsenate by algae. Further study is needed about the arsenic source/sink relationships in their vertical or horizontal profiles and the uptake mechanism during the occurrence of harmful algal blooms. | CHENG Yan REN Jingling LI Dandan LIU Sumei ZHANG Jing | 2006 | Journal of Ocean University of China2006,5,3: | 3 |

| 20 | Eco-environmental water demands for the Baiyangdian Wetland显示文摘In recent years,the hydrological characters of Baiyangdian Wetland have changed greatly,which,in turn,influence the biotic component,the structure and function of the wetland ecosystem.In order to determine the demands for water resources of ecological wetland system,a method of ecological water level coefficient was suggested to calculate the water resources demands for wetland environment use.This research showed that the minimum coefficient is 0.94 and the optimal coefficient is more than 1.10.According to these two coefficients,the ecological water level and water quantity can be estimated.The results indicate that the amount of the minimal and optimal eco-environmental water require-ments are 0.87×10^(8) and 2.78×10^(8)m^(3) in average monthly,respectively,with the maximum eco-environmental water requirement in summer and the minimum in winter.The annual change of eco-environment water demand is in accord-ing with the climate change and hydrological characters.The method of ecological water level emphasizes that wetland ecosystem adapts to the hydrological conditions,so it can be used in practice well. | Ping ZHONG Zhifeng YANG Baoshan CUI Jingling LIU | 2008 | Frontiers of Environmental Science & Engineering2008,2,1: | 2 |
