| 1 | Microbial community structures in an integrated two-phase anaerobic bioreactor fed by fruit vegetable wastes and wheat straw显示文摘The microbial community structures in an integrated two-phase anaerobic reactor(ITPAR)were investigated by 16S r DNA clone library technology.The 75 L reactor was designed with a 25 L rotating acidogenic unit at the top and a 50 L conventional upflow methanogenic unit at the bottom,with a recirculation connected to the two units.The reactor had been operated for 21 stages to co-digest fruit/vegetable wastes and wheat straw,which showed a very good biogas production and decomposition of cellulosic materials.The results showed that many kinds of cellulose and glycan decomposition bacteria related with Bacteroidales,Clostridiales and Syntrophobacterales were dominated in the reactor,with more bacteria community diversities in the acidogenic unit.The methanogens were mostly related with Methanosaeta,Methanosarcina,Methanoculleus,Methanospirillum and Methanobacterium;the predominating genus Methanosaeta,accounting for 40.5%,54.2%,73.6%and 78.7%in four samples from top to bottom,indicated a major methanogenesis pathway by acetoclastic methanogenesis in the methanogenic unit.The beta diversity indexes illustrated a more similar distribution of bacterial communities than that of methanogens between acidogenic unit and methanogenic unit.The differentiation of methanogenic community composition in two phases,as well as pH values and volatile fatty acid(VFA)concentrations confirmed the phase separation of the ITPAR.Overall,the results of this study demonstrated that the special designing of ITPAR maintained a sufficient number of methanogens,more diverse communities and stronger syntrophic associations among microorganisms,which made two phase anaerobic digestion of cellulosic materials more efficient. | Chong Wang Jiane Zuo Xiaojie Chen Wei Xing Linan Xing Peng Li Xiangyang Lu Chao Li | 2014 | Journal of Environmental Sciences2014，26，12： | 6 |
| 2 | xperimental investigation on cumulative propagation of thin film buckling under cyclic load显示文摘As instrument technology is needed for rapid determination of the smaller,thinner and lighter specimens,more stringent demands are related to thin films such as micro-electro-mechanical systems(MEMS),dielectric coatings and electronic packaging.Therefore,the requirement for testing platforms for rapidly determine the mechanical properties of thin films is increasing.Buckling of a film/substrate system could offer a variety of applications,ranging from stretchable electronics to micro-nanoscale metrology.In this paper,a fatigue-loading device has been designed to make the cyclic loading available for investigating the cumulative propagation of thin film buckling.The straight side buckling of thin compressed titanium film with the thickness of 50 nm deposited on organic glass substrates is investigated by using an optical microscope.The cumulative buckling propagation under the cyclic loading of a sequence of peak compression with the frequency 1 Hz is recorded by CCD camera.The buckling extension lengths are calculated by digital image measurement technology. | WANG ShiBin JIA HaiKun LI LinAn SUN Heng CUI DiQiang GUO ZhenShan XUE XiuLi | 2011 | Science China(Technological Sciences)2011，54，6： | 4 |
| 3 | Preparation and evaluation of sustained-release diltiazem hydrochloride pellets显示文摘In this study,diltiazem hydrochloride(DTZ)pellets were prepared successfully by extrusionespheronization method.Then methacrylic acid and ethylcellulose coating formulations were employed to make the DTZ pellets sustained release.The pellets with different coatings were investigated by in vitro dissolution tests.At last,the pellets with the best coating copolymer were subjected to pharmacokinetic studies in beagle dogs.The dissolution profiles of pellets coated with EudragitNE30D were similar to Herbesser,one of the marketed sustained release capsules.In the bioavailability study,the principal pharmacokinetic parameters of self-made pellets and the marketed ones were comparable;the relative bioavailability of DTZ sustained release capsules compared with Herbesserwas 98.536.4%.All the data indicated self-made sustained pellets could prolong the release of DTZ,decrease the fluctuation of drug level in vivo,and increase the compliance of patients. | Xiaopeng Han Linan Wang Yinghua Sun Xiaohong Liu Wanjun Liu Yuqian Du Lin Li Jin Sun | 2013 | Asian Journal of Pharmaceutical Sciences2013，8，4： | 3 |
| 4 | Doxorubicin-loaded zein in situ gel for interstitial chemotherapy of colorectal cancer显示文摘The aim of this research was to evaluate doxorubicin(DOX)-loaded zein in situ gels,a new drug delivery system in which a liquid state drug can be transformed into semi-solid after intratumoral injection.In vitro release of DOX-loaded zein was investigated and the pharmacokinetics,biodistribution and therapeutic efficacy of these DOX-loaded zein formulations were investigated using BAI B/c nude tumor-bearing mice.In vitro release of DOX from the gels extended up to 7 days.Efficient accumulation of DOX in the tumor with lower drug concentration in blood and normal organs was obtained resulting in effective inhibition of tumor growth and fewer off-target side effects.In conclusion,a DOX-loaded in situ gel was developed with sustained release,enhanced anti-cancer efficacy for colorectal cancer in vivo,and especially with reduced off-target side effects. | Ning Shen Jie Hu Linan Zhang Li Zhang Yongjun Sun Yinghua Xie Shaomei Wu Lei Liu Zibin Gao | 2012 | Acta Pharmaceutica Sinica B2012，2，6： | 3 |
| 5 | Ecological stoichiometry of nitrogen, phosphorous, and sulfur in China's forests显示文摘Much attention has been paid to the stoichiometry of carbon(C), nitrogen(N), and phosphorus(P) because of their significance for plant growth and climate change. However, other nutrients, such as sulfur(S), are often ignored. In this study, we analyzed the stoichiometry of N, P, and S in leaves of 348 plant species in China's forests. The results show higher N content and higher molar ratios of N/P and P/S in Angiospermae than in Gymnospermae. At the family level, Ulmaceae absorbed more N and P from soils than other families, and Cupressaceae absorbed more S than other families. In addition,except for bamboo and other tropical forests, leaf N and P content of China's forests generally increased from low to middle latitudes and then slightly decreased or plateaued at high latitudes. Plant ecotypes, taxonomic groups, environmental conditions, atmospheric S precipitation, and soil-available N and P significantly affected the distribution and stoichiometry of leaf N, P, and S in China's forests.Our study indicates that China's forests are likely limited by P and S deficiencies which may increase in the future. | Yuntao Wu Hongyan Liu Zhaoliang Song Xiaomin Yang Zichuan Li Qian Hao Linan Liu | 2017 | Acta Geochimica2017，36，3： | 2 |
| 6 | Characterization of Genome-Wide Microsatellites of Saccharina japonica Based on a Preliminary Assembly of Illumina Sequencing Reads显示文摘Microsatellites or simple sequence repeats(SSR) function widely and locate dependently in genome. However, their characteristics are often ignored due to the lack of genomic sequences of most species. Kelp(Saccharina japonica), a brown macroalga, is extensively cultured in China. In this study, the genome of S. japonica was surveyed using an Illumina sequencing platform, and its microsatellites were characterized. The preliminarily assembled genome was 469.4 Mb in size, with a scaffold N_(50) of 20529 bp. Among the 128370 identified microsatellites, 90671, 25726 and 11973 were found in intergenic regions, introns and exons, averaging 339.3, 178.8 and 205.4 microsatellites per Mb, respectively. These microsatellites distributed unevenly in S. japonica genome. Mononucleotide motifs were the most abundant in the genome, while trinucleotide ones were the most prevalent in exons. The microsatellite abundance decreased significantly with the increase of motif repeat numbers, and the microsatellites with a small number of repeats accounted for a higher proportion of the exons than those of the intergenic regions and introns. C/G-rich motifs were more common in exons than in intergenic regions and introns. These characteristics of microsatellites in S. japonica genome may associate with their functions, and ultimately their adaptation and evolution. Among the 120140 pairs of designed microsatellite primers, approximately 75% were predicted to be able to amplify S. japonica DNA. These microsatellite markers will be extremely useful for the genetic breeding and population evolution studies of kelp. | ZHANG Linan PENG Jie LI Xiaojie CUI Cuiju SUN Juan YANG Guanpin | 2016 | Journal of Ocean University of China2016，15，3： | 2 |

| 15 | A High-Temperature Superconducting Wideband Bandpass Filter at the L Band for Radio Astronomy显示文摘In order to ensure the normal operation of radio astronomy observations,an extremely sensitive receiver system needs to be equipped in front of the large radio telescope.An 8-pole wideband high-temperature superconducting(HTS)filter using a Coplanar Spiral Resonator Structure with a passband of 1160~1670 MHz is developed to suppress strong radio interference.The filter is fabricated on a 36 mm×14 mm YBCO HTS film,which is deposited on a 0.5 mm thick MgO substrate.The minimum insertion loss measured in the liquid nitrogen temperature region is 0.03 dB,and the first parasitic passband appears at 2600 MHz.The measured results are in good agreement with the simulations.The filter can be used in radio telescope receivers for the observation of neutral hydrogen and pulsars,as well as in high-sensitivity satellite navigation instruments. | Xinyu Zhu Jianbin Li Boyu Lu Bin Wei Yifan Jiang Linan Jiang Chao Hu | 2023 | Research in Astronomy and Astrophysics2023，23，11： | 0 |
| 16 | Clamping effect driven design and fabrication of new infrared birefringent materials with large optical anisotropy显示文摘Infrared(IR)birefringent materials with large optical anisotropy and wide transparency range are important for efficient light manipulation in various IR optical devices.Herein,two new IR birefringent materials AMgGeSe_(3)(A=Li,Na)with large optical anisotropy were rationally designed by a rigid octahedron and flexible dimer combined strategy and fabricated in experiment.The introduction of rigid[LiSe_(6)]/[NaSe_(6)]and[MgSe_(6)]octahedra effectively regulates the geometry and arrangement of the flexible[Ge2Se6]dimers,resulting in the birefringence as large as 0.334@1,064 nm in LiMgGeSe_(3) and 0.445@1,064 nm(the largest one in the reported[Ge_(2)Se_(6)]dimer-contained selenides)in NaMgGeSe_(3).Density functional theory(DFT)calculations and statistical analyses highlight the influence of polarizability anisotropy,density,arrangement of units,as well as layer distance on birefringence.The results indicate that AMgGeSe_(3)(A=Li,Na)crystals are the promising IR birefringent materials and it gives an insight into the exploration of new IR birefringent materials with large birefringence based on the clamping effect from rigid groups. | Linan Wang Chenchen Tu Hongbo Gao Jiazheng Zhou Hongshan Wang Zhihua Yang Shilie Pan Junjie Li | 2023 | Science China Chemistry2023，66，4： | 0 |
| 17 | Analysis of Clinicopathologic Features of Esophageal Carcinoma Patients Undergoing Surgery-a Report of 4,329 Cases显示文摘OBJECTIVE To investigate the clinicopathological features of esophageal carcinoma(EC)patients,and to analyze epidemiologic characteristics and the current situation of esophageal cancioma in the southern area of Hebei Province. METHODS A total of 4329 patients with esophageal cancinoma, undergoing surgery in the Fourth Hospital of Hebei Medical University during a period from January 1996 to December 2005, were selected.Collection and statistical analysis of the pathologic data were performed using a SAS 6.0 so ware package. RESULTS Over the past ten years,there has been a tendency for an increase in the mean age of EC onset(P<0.05),a downtrend in the percentage of squamous cancer(SqCa)(P<0.05)and an uptrend in the frequency of small cell carcinoma(P<0.05).In clinical stages,there was a drop in the percentage of Stage-II squamous EC patients(P<0.05),and an increase in that of Stage- IV patients(P<0.05).There were statistical differences in sex,age, pathologic types,depth of infiltration,ratio of stages and lymph node metastasis,etc.among the superior,middle and inferior segments of the EC diseased region(P<0.05). CONCLUSION It was relatively late for the EC patients from this area to see a doctor,resulting in a drop in the ratio of SqCa and an ascensus in that of small cell cancer.However,due to a low incidence of adenocarcinoma,no obvious ascending tendency was found in the frequency of this carcinoma over the past ten years. | Wei Liu Xishan Hao Ying Jin Haixin Li Linan Song Shijie Wang Peizhong Wang Yong Chen Qian Fan Liyun Guan Yumin Ping Xianli Meng Rui Wang Junfeng Liu Xiaoling Wang | 2008 | Chinese Journal of Clinical Oncology2008，5，2： | 0 |
| 18 | Epigenetic modification associated with climate regulates betulin biosynthesis in birch显示文摘The Betula genus contains pentacyclic triterpenoid betulin known for its environmental adaptation and medicinal properties.However,the mechanisms underlying betulin biosynthesis responding to climate change remain unclear.In this study,the role of epigenetic modification(DNA methylation) in betulin biosynthesis was examined and how climatic factors influence it.Whole-genome bisulfite sequencing was performed for greenhouse-grown Chinese white birch(Betula platyphylla Sukaczev) treated with DNA methylation inhibitor zebularine(ZEB) and a natural birch population in Northeast China.ZEB treatment significantly affected the CHH methylation level of transposable elements and betulin content in a hormesis dose-dependent manner.The methylation and expression of bHLH9,a key transcriptional factor controlling betulin biosynthesis,were also consistently affected by ZEB treatment as a hormetic dose-response.In the natural population,there was a positive correlation between promoter methylation of bHLH9 and summer precipitation,while winter temperature was negatively correlated.Thus climate-dependent methylation of bHLH9 regulates the expression of downstream genes involved in betulin biosynthesis.This study highlights the role of environmental signals to induce epigenetic changes that result in betulin production,possibly helping to develop resilient plants to combat ongoing climate change and enhance secondary metabolite production. | Jiang Wang Bowei Chen Shahid Ali Tianxu Zhang Yu Wang He Zhang Lishan Wang Yonglan Zhang Linan Xie Tingbo Jiang Jing Yin Heike W.Sederoff Gaurav Zinta Ronald R.Sederoff Yuhua Li Qingzhu Zhang | 2023 | Journal of Forestry Research2023，34，1： | 0 |
| 19 | Analysis of Prognostic Factors of Esophageal and Gastric Cardiac Carcinoma Patients after Radical Surgery Using Cox Proportional Hazard Model-A Random Sampling Study from the Fourth Hospital of Hebei Medical University during the Period of 1996-2004显示文摘OBJECTIVE To retrospectively analyze clinical data of patientsfrom our hospital who underwent radical surgery for esophagealcarcinoma and for adenocarcinoma of the gastric cardia,as well asto investigate prognostic factors affecting the long-term survival ofthe patients.METHODS Data from the patients eligible for our study,admitted to the 4th Hospital of Hebei Medical University fromJanuary 1996 to December 2004,were randomized,and 12distinctive clinicopathologic factors influencing the survival rateof those who underwent radical surgery for esophageal carcinomaor carcinoma of the gastric cardia were collected.Univariate andmultivariate analysis of these individual variables were performedusing the Cox proportional hazard model.RESULTS It was shown by univariate analysis that age,tumorsize,pathologic type,lymph node status,TNM staging,depthof infiltration and encroachment into local organs,etc.,were thefactors that markedly influenced the prognosis of patients(P<0.01).Multivariate analysis showed that pathologic type,numberof the lymph node metastases,involvement of local organs,andTNM staging were independent prognostic factors(P<0.05).CONCLUSION The independent factors influencing theprognosis of patients with esophageal cancer and carcinoma ofthe gastric cardia include pathologic type,number of lymph nodemetastases,involvement of local organs and TNM staging.Themain prognostic factors affecting the patient's survival are patientage,tumor size and depth of infiltration.In addition,patients withinvolvement of the local organs have a worse prognosis,and theyshould be closely followed up. | Wei Liu Xishan Hao Qian Fan Peizhong Wang Haixin Li Linan Song Shijie Wang Ying Jin Yong Chen Liyun Guan Yumin Ping Xianli Meng Rui Wang Junfeng Liu Xiaoling Wang | 2009 | Clinical oncology and cancer resexreh2009，6，4： | 0 |
| 20 | Suppressing byproduct formation for high selective CO_(2) reduction over optimized Ni/TiO_(2) based catalysts显示文摘One of the challenges for catalytic CO_(2)reduction is to control product selectivity,and new findings that can modify selectivity would be transformative.Herein,two kinds of TiO_(2)(homemade and commercial)with the same crystal phase but different surface properties are chosen as supports to prepare Ni-based catalysts for CO_(2)reduction,which show distinctly different product selectivity for CO_(2)reduction to CH_(4) or CO,as well as the CO_(2)conversion.The catalysts based on the homemade TiO_(2)support are highly selective for CH_(4) formation,while the latter ones are about 100%selective for CO formation under the same reaction conditions.In addition,the former ones are much active(more than 3 times)than the latter ones.We found that the collaborative contribution of Ti^(3+)and Ni^(2+)species and the electronic metal-support interactions effect maybe the main driving force behind for determining the product selectivity.Methane is almost exclusively produced over the catalysts with abundant Ti^(3+)and Ni^(2+)species and greater electronic metal-support interaction,otherwise,it will give priority to CO generation.The addition of CeO_(2)can reduce the Ni particle size and improve the dispersion of Ni nanoparticles,as well as create more Ti^(3+)species,contributing to the enhancement of CO_(2)conversion,but shows a negligible effect on product selectivity.Furthermore,the in situ DRIFT experiments and kinetic experiments indicate that the CO route is probably involved in the CO_(2)reduction process over the homemade Ni-CeO_(2)/TiO_(2)-CO catalyst with abundant Ti^(3+)and Ni^(2+)species and a strong electronic transform effect. | Danyang Li Ruidong Xu Roong Jien Wong Xing Zhu Dong Tian Lei Jiang Qingjie Guo Hongcun Bai Linan Huang Wen Liu Hua Wang Kongzhai Li | 2022 | Journal of Energy Chemistry2022，31，9： | 0 |
