| 1 | Magnetostratigraphy of the late Cenozoic Laojunmiao anticline in the northern Qilian Mountains and its implications for the northern Tibetan Plateau uplift显示文摘Cenozoic sediments in the foreland basin--Jiuquan Basin in west Hexi Corridor recorded tectonic uplift information of the Qilian Mountains. High resolution paleomagnetic dating of the Laojunmiao (LJM) section across the central LJM anticline in the southern Jiuquan Basin reveals ages of the Getanggou Member, Niugetao Member in the Shulehe Formation, the Yumen Conglomerate, Jiuquan Conglomerate and Gobi Formation at >13-8.3 Ma, 8.3-4.9 Ma, 3.66-0.93 Ma, 0.84-0.14 Ma and 0.14-0 Ma, respectively. Sedimentary evolution study suggests that the Qilian Mountains should begin to rise gradually since ~8-6.6 Ma, accompanied by sedimentary environments changing from lacustrine mudstones-sandstones to alluvial conglomerates. Rapid uplift of the Qilian Mountains began at ~3.66 Ma, followed by a series of stepwise or intermittent intensive uplifts at about <1.8-1.23 Ma, 0.93-0.84 Ma and 0.14 Ma, which finally resulted in the present high Qilian Mountains. | FANG Xiaomin1,2, ZHAO Zhijun3,2, LI Jijun2, YAN Maodu2, PAN Baotian2, SONG Chunhui2 & DAI Shuang2 1.

| 2 | Land use changes and their relations with carbon cycles over the past 300 a in China显示文摘Land use and land cover in China have changed greatly during the past 300 a, indicated by the rapid abrupt decrease of forest land area and the rapid increase of cropland area, which can affect terrestrial carbon cycle greatly. The first-hand materials are used to analyze main characteristics for land use and land cover changes in China during the study period. The following conclusions can be drawn from this study. The cropland area in China kept increasing from 60.78×106 hm2 in 1661 to 96.09×106 hm2 in 1998. Correspondingly, the forest land area decreased from 248.13×106 hm2 in 1700 to 109.01×106 hm2 in 1949. Affected by such changes, the terrestrial ecosystem carbon storage decreased in the mean time. Car-bon lost from land use and land cover changes mainly consist of the loss from vegetation biomass and soil. In the past 300 a, about 3.70 PgC was lost from vegetation biomass, and emissions from soil ranged from 0.80 to 5.84 PgC. The moderate evaluation of soil losses was 2.48 PgC. The total loss from vegetation and soil was between 4.50 and 9.54 PgC. The moderate and optimum evaluation was 6.18 PgC. Such carbon losses distribution varied spatially from region to region. Carbon lost more significantly in Northeast China and Southwest China than in other regions, because losses of forest land in these two regions were far greater than in the other regions during the past 300 a. And losses of carbon in the other regions were also definite, such as Inner Mongolia, the western part of South China, the Xinjiang Uygur Autonomous Region, and the Qinghai-Tibet Plateau. But the carbon lost very little from the traditional agricultural regions in China, such as North China and East China. Studies on the relationship between land use and land cover change and carbon cycle in China show that the land use activities, especially those related to agriculture and forest management, began to affect terrestrial carbon storage positively in recent years. | GE QuanSheng DAI JunHu HE FanNeng PAN Yuan WANG MengMai | 2008 | Science China Earth Sciences2008,51,6: | 30 |
| 3 | NUMERICAL SIMULATION FOR 2D SHALLOW WATER EQUATIONS BY USING GODUNOV-TYPE SCHEME WITH UNSTRUCTURED MESH显示文摘In order to establish a well-balanced scheme, 2D shallow water equations were transformed and solved by using the Finite Volume Method (FVM) with unstructured mesh. The numerical flux from the interface between cells was computed with an exact Riemann solver, and the improved dry Riemann solver was applied to deal with the wet/dry problems. The model was verified through computing some typical examples and the tidal bore on the Qiantang River. The results show that the scheme is robust and accurate, and could be applied extensively to engineering problems. | PAN Cun-hong DAI Shi-qiang CHEN Sen-mei | 2006 | Journal of Hydrodynamics2006,18,4: | 25 |

| 6 | Characterization of mitochondrial genome of Chinese wild mulberry silkworm, Bomyx mandarina(Lepidoptera:Bombycidae)显示文摘The complete mitochondrial genome of Chinese Bombyx mandarina(ChBm) was determined.The cir-cular genome is 15682 bp long, and contains a typical gene complement, order, and arrangement iden-tical to that of Bombyx mori(B.mori) and Japanese Bombyx mandarina(JaBm) except for two addi-tional tRNA-like structures:tRNASer(TGA)-like and tRNAIle(TAT)-like.All protein-coding sequences are initi-ated with a typical ATN codon except for the COI gene, which has a 4-bp TTAG putative initiator codon.Eleven of 13 protein-coding genes(PCGs) have a complete termination codon(all TAA), but the re-maining two genes terminate with incomplete codons.All tRNAs have the typical clover-leaf structures of mitochondrial tRNAs, with the exception of tRNASer(TGA)-like, with a four stem-and-loop structure.The length of the A+T-rich region of ChBm is 484 bp, shorter than those of JaBm(747 bp) and B.mori(494―499 bp).Phylogenetic analysis among B.mori, ChBm, JaBm, and Antheraea pernyi(Anpe) showed that B.mori is more closely related to ChBm than JaBm.The earliest divergence time estimate for B.mori-ChBm and B.mori-JaBm is about 1.08±0.18―1.41±0.24 and 1.53±0.20―2.01±0.26 Mya, respec-tively.ChBm and JaBm diverged around 1.11±0.16―1.45±0.21 Mya. | PAN MinHui1, YU QuanYou1, XIA YuLing1, DAI FangYin1, LIU YanQun2, LU Cheng1, ZHANG Ze1 & XIANG ZhongHuai1 1 Key Sericultural Laboratory of Agricultural Ministry, Southwest University, Chongqing 400716, China 2 College of Bioscience and Biotechnology, Shenyang Agricultural University, Shenyang 110161, China | 2008 | Science China(Life Sciences)2008,51,8: | 16 |
| 7 | A system dynamics approach for water resources policy analysis in arid land:a model for Manas River Basin显示文摘The Manas River Basin in Xinjiang Uygur autonomous region,similar to other arid regions,is facing water constraints which challenge decision-makers as to how to rationally allocate the available water resources to meet the demands from industries and natural ecosystems.Policies which integrate the supply and demand are needed to address the water stress issues.An object-oriented system dynamics model was developed to capture the interrelationships between water availability and increasing water demands from the growth of industries,agricultural production and the population through modeling the decision-making process of the water exploration explicitly,in which water stress is used as a major indicator.The model is composed of four sectors:1) natural surface and groundwater resources;2) water demand;3) the water exploitation process,including the decision to build reservoirs,canals and pumps;4) water stress to which political and social systems respond through increasing the supply,limiting the growth or improving the water use efficiency.The model was calibrated using data from 1949 to 2009 for population growth,irrigated land area,industry output,perceived water stress,groundwater resources availability and the drying-out process of Manas River;and simulations were carried out from 2010 to 2050 on an annual time step.The comparison of results from calibration and observation showed that the model corresponds to observed behavior,and the simulated values fit the observed data and trends accurately.Sensitivity analysis showed that the model is robust to changes in model parameters related to population growth,land reclamation,pumping capacity and capital contribution to industry development capacity.Six scenarios were designed to investigate the effectiveness of policy options in the area of reservoir relocation,urban water recycling,water demand control and groundwater pumping control.The simulation runs demonstrated that the technical solutions for improving water availability and water use efficiency are not sustainable.Acknowledging the carrying capacity of water resources and eliminating a growth-orientated value system are crucial for the sustainability of the Manas River Basin. | ShanShan DAI LanHai LI HongGang XU XiangLiang PAN XueMei LI | 2013 | Journal of Arid Land2013,5,1: | 14 |

| 9 | Expressions of chromogranin A and cathepsin D in human primary hepatocellular carcinoma显示文摘AIM To determine the expression and clinicalsignificance of chromogranin A and cathepsin Din hepatocellular carcinoma(HCC).METHODS Double immunofluorescence stain-ing techniques combined with laser confocalscanning microscopy(LSCM)was used toinvestigate chromogranin A and cathepsin Dexpressions in 85 HCC patients.RESULTS Cathepsin D was expressed in :3normal liver tissues,while in HCC the stainingshowed regional variation and the fraction ofstrongly stained cells increased as the tumorsbecame less differentiated and usually clinicallymore malignant.Cells which showed strongpositivity for cathepsin D were present in 71/85(83.5%)cases.Strong expression of cathepsinD in cancer cells was related tohistopathological features.They were morecommon in grade 3-4(26/28,92.9%)and grade2(46/53,86.8%)tumors than in grade 1 tumors(1/4,25.0%)(P<0.01).No significantcorrelation was found between age andcathepsin D expression.In patients with positivecathepsin D reaction,the mean age was 52.1±2.8 years(range 32-68 years)and in the groupwith negative reaction,the mean age was 51.3±4.5 years(range 28-71 years).No obvious relationship was observed between CgAexpression in cancer cells and thehistopathological features.The CgA positiverate was 75.0%(3/4)in grade 1,71.7%(38/53)in grade 2,and 71.4%(20/28)in grade 3-4(P>0.05)tumors.The coexpression of CgA andcathepsin D was found by double labeledimmunofluorescence staining techniques.Theprocessing of cathepsin D was disturbed in HCCcells and accumulated in the cells.Cathepsin Dhad proteolytic activity and autocrine mitogeniceffect,suggesting their functions in invasion.These findings demonstrated that the expressionof cathepsin D in HCC had prognostic value.CONCLUSION Chromogranin A and cathepsin Dare expressed in a high proportion of HCC andthe existence of cathepsin D in HCC might berelated to processing of CgA.This is clearly asubject for further studies because of itspotential clinical applications. | Xiao Feng Huang Chun Mei Wang Xiao Wen Dai Zhen Jiang Li Bo Rong Pan Li Bin Yu Bin Qian Li Fang | 2000 | World Journal of Gastroenterology2000,6,5: | 12 |
| 10 | Inhibitive effects of anti-oxidative vitamins on mannitol-induced apoptosis of vascular endothelial cells显示文摘Objective: Study blood vessel injury and gene expression indicating vascular endothelial cell apoptosis induced by mannitol with and without administration of anti-oxidative vitamins. Methods: Healthy rabbits were randomly divided into four groups. Mannitol was injected into the vein of the rabbit ear in each animal. Pre-treatment prior to mannitol injection was per- formed with normal saline (group B), vitamin C (group C) and vitamin E (group D). Blood vessel injury was assessed under electron and light microscopy. In a second experiment, cell culture specimen of human umbilical vein endothelial cells were treated with mannitol. Pre-treatment was done with normal saline (sample B), vitamin C (sample C) and vitamin E (sample D). Total RNA was extracted with the original single step procedure, followed by hybridisation and analysis of gene expression. Results: In the animal experiment, serious blood vessel injury was seen in group A and group B. Group D showed light injury only, and normal tissue without pathological changes was seen in group C. Of all 330 apoptosis-related genes analysed in human cell culture specimen, no significant difference was seen after pre-treatment with normal saline, compared with the gene chip without pre-treatment. On the gene chip pre-treated with vitamin C, 45 apoptosis genes were down-regulated and 34 anti-apoptosis genes were up-regulated. Pre-treatment with vitamin E resulted in the down-regulation of 3 apoptosis genes. Conclusion: Vitamin C can protect vascular endothelial cells from mannitol-induced injury. | PAN Kai-yu SHEN Mei-ping YE Zhi-hong DAI Xiao-na SHANG Shi-qiang | 2006 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2006,7,10: | 11 |
| 11 | Influence of different extrusion processes on mechanical properties of magnesium alloy显示文摘AZ31 Mg alloy sheets were processed by the conventional symmetrical extrusion(CSE)and the asymmetric extrusion(ASE).Progressive-asymmetric extrusion(PASE)and severe strain-asymmetric extrusion(SASE)were employed for ASE processes.The texture at near-surface and mid-layer zones of ASE sheets was diverse penetrating the normal direction(ND).This was attributed to an additional asymmetric shear strain deformation during the ASE process.(0002)basal planes of PASE sheets tilt to the shear deformation direction.Meanwhile,the basal texture intensity of PASE sheets has been weakened compared with one in CSE sheets.Grain refinement and tilted weak basal texture obtained by SASE process dramatically enhances the room temperature strength and plasticity of the extruded AZ31 magnesium alloy sheets.The microstructure and mechanical responses were examined and discussed. | Qingshan Yang Bin Jiang Hucheng Pan Bo Song Zhongtao Jiang Jiahong Dai Lifei Wang Fusheng Pan | 2014 | Journal of Magnesium and Alloys2014,2,3: | 11 |
| 12 | Production of porcine cloned transgenic embryos expressing green fluorescent protein by somatic cell nuclear transfer显示文摘In the present study, nuclear transferred embryos (NTEs) were reconstructed by using pig fetal fibroblasts as donors and in vitro matured oocytes as recipients. The effects of G418 selection on donor cells, duration of IVM of prepubertal gilt oocytes and oxygen tension in IVM of oocytes were investigated. The results were as follows: (i) When G418 selected cells expressing GFP were used as donors, the cleavage rate of NTEs decreased drastically in comparison to NTEs derived from donors without antibiotic selection (47.5% vs. 71.6%, p<0.05). For the blastocyst rate, no significant differ-ence was observed between two groups (10% vs. 10.4%, p>0.05). (ii) The rate of nuclear maturation of oocytes increased significantly when IVM duration time was extended from 36 to 42 h (83.6% vs. 96.7%, p<0.05). However, no statistical difference was observed between NTEs derived from oocytes of 36 h IVM group and NTEs from oocytes of 42 h IVM group in the rates of cleavage (59.3% vs. 73.6%, p>0.05) and blastocyst formation (9.3% vs. 13.2%, p>0.05); (iii) no significant difference was observed between NTEs reconstructed from oocytes matured under lower oxygen (7% O2) tension and NTEs derived from oocytes matured under higher oxygen tension (20% O2) in cleavage rate (70.6% vs. 67.1%, p>0.05) and blastocyst rate (11.8% vs. 12.3%, p>0.05). These results suggest that: (i) G418 selection does not have a significant effect on cleavage rate of NTEs expressing GFP. (ii) Nuclear maturation is greatly improved by prolonging IVM duration from 36 to 42 h, while no signifi-cant differences were observed for developmental potential of transgenic embryos. Thus IVM 42 h is the better choice in order to obtain maximum number of MⅡ oocytes as recipients. (iii) Lower oxygen tension and higher oxygen tension in IVM have no significant effect on development of cloned em-bryos. | ZHANG Yunhai1, PAN Dengke1,2, SUN Xiuzhu1, SUN Guojie1, WANG Xiaobo1, LIU Xiaohui1, LI Yan1, DAI Yunping1 & LI Ning1 1.

| 13 | Economic burden and its associated factors of hospitalized patients infected with A (H7N9) virus: a retrospective study in Eastern China, 2013–2014显示文摘Background:H7N9 continues to cause human infections and remains a pandemic concern.Understanding the economic impacts of this novel disease is important for making decisions on health resource allocation,including infectious disease prevention and control investment.However,there are limited data on such impacts.Methods:Hospitalized laboratory-confirmed H7N9 patients or their families in Jiangsu Province of China were interviewed.Patients’direct medical costs of hospitalization were derived from their hospital bills.A generalized linear model was employed to estimate the mean direct medical costs of patients with different characteristics.Results:The mean direct cost of hospitalization for H7N9 was estimated to be¥71060(95%CI,48180–104820),i.e.,US$10996(95%CI,7455–16220),and was¥12060(US$1861),¥136120(US$21001)and¥218610(US$33728)for those who had mild or severe symptoms or who died,respectively.The principal components of the total fees differed among patients with different disease severity,although medication fees were always the largest contributors.Disease severity,proportion of reimbursement and family member monthly average income were identified as the key factors that contributed to a patient’s direct medical cost of hospitalization.Conclusions:The direct medical costs of hospitalized patients with H7N9 are significant,and far surpass the annual per capita income of Jiangsu Province,China.The influencing factors identified should be taken into account when developing related health insurance policies and making health resource allocation.Trial registration:Not applicable.This is a survey study with no health care intervention implemented on human participants. | Xiang Huo Li-Ling Chen Lei Hong Lun-Hui Xiang Fen-Yang Tang Shan-Hui Chen Qiang Gao Cong Chen Qi-gang Dai Chuan-Wu Sun Ke Xu Wen-Jun Dai Xian Qi Chang-Cheng Li Hui-Yan Yu Yin Zhou Hao-Di Huang Xing-Yang Pan Chang-sha Xu Ming-Hao Zhou Chang-Jun Bao | 2016 | Infectious Diseases of Poverty2016,5,1: | 10 |
| 14 | Characterization and evaluation of rice blast resistance of Chinese indica hybrid rice parental lines显示文摘The development of resistant varieties and hybrid combinations has been the most effective and economical strategy to control blast disease caused by Magnaporthe oryzae.However, the distribution of major R genes and blast resistance characterization in hybrid rice parents has not been well investigated, resulting in their limited use in hybrid rice blast-resistance breeding. In the present study, 88 elite indica hybrid rice parental lines were evaluated with 30 isolates of M. oryzae collected from the main planting area of indica hybrid rice in China and were characterized for the presence of 11 major resistance genes using molecular markers. The pathogenicity assays showed that four types of hybrid rice parent line showed some resistance to M. oryzae. However, the proportions of highly resistant lines and the mean resistance frequency(RF) varied among the four types, with resistance in decreasing order shown by three-line restorer lines, three-line maintainer lines, two-line sterile lines, and two-line restorer lines. All 88 hybrid rice parental lines carried more than one R gene, but none carried the R genes Pi1 and Pi2. Although Pid3 and Pi9 were present only in three-line restorer lines and Pigm only in three-line maintainer lines, the remaining six R genes(Pib, Pid2, Pi5, Pia, Pi54, and Pita) were present in the four types of hybrid rice parent with significantly different distribution frequencies. The correlation between R genes and resistance reactions was investigated. The results are expected to provide useful information for rational utilization of major R genes in hybrid rice breeding programs. | Yunyu Wu Ling Yu Ning Xiao Zhengyuan Dai Yuhong Li Cunhong Pan Xiaoxiang Zhang Guangqing Liu Aihong Li | 2017 | The Crop Journal2017,5,6: | 10 |
| 15 | Comparative pharmacokinetics of bergenin,a main active constituent of Saxifraga stolonifera Curt.,in normal and hepatic injury rats after oral administration显示文摘Bergenin, isolated from the herb of Saxifrage stolonifera Curt.(Hu-Er-Cao) has hepatoprotective, anti-inflammatory, antitussive, and neuroprotective activities. The aim of the present study was to establish a simple, rapid, and sensitive RP-HPLC method for determination of bergenin in rat plasma and compare its oral pharmacokinetic behaviors in normal and CCl_4-induced hepatic injury rats. With norisoboldine as an internal standard, chromatographic separation was performed on a C_(18) analytical column with acetonitrile and water(11 : 89, V/V) containing 0.1% formic acid as the mobile phase. A good linearity was obtained over the range of 100^(–1)0 000 ng·m L^(–1). The lower limit of quantification was 50 ng·m L~(^(–1)). The developed method was successfully applied to a study of the pharmacokinetic difference of bergenin(100 mg·kg^(–1)) between normal and hepatic injury rats after oral administration. Marked alterations of pharmacokinetic parameters in hepatic injury rats were observed. Compared to normal rats, the AUC_((0–∞)) of bergenin in hepatic injury rats was elevated to 2.11-fold and C_(max) was increased by 130%, whereas CL value was only 55% of the normal rats, suggesting that the systemic exposure of bergenin was significantly increased under hepatic injury status. | PAN Rong-Hua HE Hong-Mei DAI Yue XIA Yu-Feng | 2016 | Chinese Journal of Natural Medicines2016,14,10: | 10 |
| 16 | Force-induced charge carrier storage:a new route for stress recording显示文摘Stress sensing is the basis of human-machine interface,biomedical engineering,and mechanical structure detection systems.Stress sensing based on mechanoluminescence(ML)shows significant advantages of distributed detection and remote response to mechanical stimuli and is thus expected to be a key technology of next-generation tactile sensors and stress recorders.However,the instantaneous photon emission in ML materials generally requires real-time recording with a photodetector,thus limiting their application fields to real-time stress sensing.In this paper,we report a force-induced charge carrier storage(FICS)effect in deep-trap ML materials,which enables storage of the applied mechanical energy in deep traps and then release of the stored energy as photon emission under thermal stimulation.The FICS effect was confirmed in five ML materials with piezoelectric structures,efficient emission centres and deep trap distributions,and its mechanism was investigated through detailed spectroscopic characterizations.Furthermore,we demonstrated three applications of the FICS effect in electronic signature recording,falling point monitoring and vehicle collision recording,which exhibited outstanding advantages of distributed recording,longterm storage,and no need for a continuous power supply.The FICS effect reported in this paper provides not only a breakthrough for ML materials in the field of stress recording but also a new idea for developing mechanical energy storage and conversion systems. | Yixi Zhuang Dong Tu Changjian Chen Le Wang Hongwu Zhang Hao Xue Conghui Yuan Guorong Chen Caofeng Pan Lizong Dai Rong-Jun Xie | 2020 | Light(Science & Applications)2020,9,1: | 10 |
| 17 | Developmental Changes of the LPL mRNA Expression and Its Effect on IMF Content in Sheep Muscle显示文摘This study investigates the developmental changes of the lipoprotein lipase (LPL) mRNA level in sheep muscle and its effect on intramuscular fat (IMF) accumulation. Male Kazak and Xinjiang Merino sheep at 2-120 days old were selected. Six animals of each breed were slaughtered at 2,30,60,90,and 120 days (only the Xinjiang Merino sheep at 120-day old were available) to collect samples from longissimus dorsi muscle for the purpose of determining the IMF content and extracting total RNA that was used to investigate the developmental changes of the LPL mRNA expression by real-time PCR. The results showed that in male Kazak sheep,the IMF content increased with the progress of development and there were significant differences (P < 0.05) between the age groups. However,there was no difference (P > 0.05) between age groups in Xinjiang Merino sheep. Furthermore,the IMF content of the male Kazak sheep was significantly higher (P < 0.01) than that of the Xinjiang Merino sheep aged from 30 to 90 days. The highest LPL mRNA expression appeared at day 2 and it was significantly higher than that of all other age groups (P < 0.01),while animals at 60-day old had the lowest LPL mRNA expression in the male Kazak sheep. In Xinjiang Merino sheep,the highest one occurred at 30-day old (P < 0.01),followed by a continuous decrease to the lowest level at 90-day old,and then it started to increase slightly. At 2 to 60-day old,the LPL mRNA expression was negatively correlated to the IMF content (r = -0.625,P < 0.05) in male Kazak sheep,but no such relationship was detected in the male Xinjiang Merino sheep. | QIAO Yong HUANG Zhi-guo LI Qi-fa LIU Zhen-shan DAI Rong PAN Zeng-xiang XIE Zhuang LIU Hong-lin | 2008 | Agricultural Sciences in China2008,7,1: | 9 |
| 18 | Trends of Overweight and Obesity in Yi People between 1996 and 2007:An Yi Migrant Study显示文摘Objective To evaluate trends of overweight and obesity prevalence between 1996 and 2007 in Yi farmers and Yi migrants.Methods An Yi migrant study was conducted in Liangshan Yi Autonomous Prefecture,Sichuan Province,China from 1996 to 2007.Data were collected with identical methods,including standardized questionnaire and body measurements.Results Age‐ and sex‐specific body mass index (BMI) significantly increased from 20.02 in 1996 to 22.36 in 2007,among Yi farmers,which was significantly different from those among Yi migrants (23.67 in 2007 and 20.90 in 1996) (P<0.05).Prevalence of obesity rose from 1.21 % in 1996 to 4.55 % in 2007 (OR=1.15,P<0.001) in Yi migrants,while that in Yi farmers from none in 1996 to 0.12 % in 2007 (P>0.05).Prevalence of overweight rose significantly to 26.24 %in 2007 from 17.24 % in 1996 (OR=1.06,P<0.001) in Yi migrants,while that in Yi farmers from 1.29 % in 1996 to 4.45 % in 2007 (OR=1.14,P<0.001).Yi migrants appeared to have a 5.52‐fold higher risk ondeveloping overweight and obesity than Yi farmers have.Conclusion The Yi migrants had a steeper increase of overweight with year and consequently caused more obesity.Change in lifestyle may contribute most likely to higher prevalence of overweight and obesity in Yi migrants. | SHAN GuangLiang WEI DaYing WANG ChunXiu ZHANG JianHua Wang Bin MA MingJu PAN Li YU Tao XUE Fang WU ZhengLai | 2011 | Biomedical and Environmental Sciences2011,24,5: | 9 |

| 20 | Fabrication and evaluation of molecularly imprinted regenerated cellulose composite membranes via atom transfer radical polymerization显示文摘A simple and effective method for surface molecularly imprinted composite membranes(MICMs) for artemisinin(Ars) based on regenerated cellulose membranes was first prepared through surfaceinitiated atom transfer radical polymerization(ATRP),and the as-prepared MICMs were then evaluated as adsorbents for selective recognition and separation of Ars molecules.Batch rebinding studies were conducted to determine the specific adsorption equilibrium,kinetics and selective permeation performance.The adsorption capacity of MICMs toward Ars by the Langmuir isotherm model was2.008 mg g^(-1),which was nearly 5.0 times higher than non-molecularly imprinted composite membranes(NICMs).The kinetic property of MICMs was well-fitted by the pseudo-second-order rate equation.The selective permeation experiments were successfully investigated to prove the excellent selective permeation performance for Ars than the competitive analog(artemether). | Yi-Lin Wu Yong-Sheng Yan Jian-Ming Pan Xiao-Hui Dai Wei-Dong Shi Min-Jia Meng | 2014 | Chinese Chemical Letters2014,25,2: | 9 |
