2Facile Synthesis of Porous Carbon Nitride Spheres with Hierarchical Three-Dimensional Mesostructures for CO_(2) Capture显示文摘Porous carbon nitride(CN)spheres with partially crystalline frameworks have been successfully synthesized via a nanocasting approach by using spherical mesoporous cellular silica foams(MCFs)as a hard template,and ethylenediamine and carbon tetrachloride as precursors.The resulting spherical CN materials have uniform diameters of ca.4μm,hierarchical three-dimensional(3-D)mesostructures with small and large mesopores with pore diameters centered at ca.4.0 and 43 nm,respectively,a relatively high BET surface area of~550 m^(2)/g,and a pore volume of 0.90 cm^(3)/g.High-resolution transmission electron microscope(HRTEM)images,wide-angle X-ray diffraction(XRD)patterns,and Raman spectra demonstrate that the porous CN material has a partly graphitized structure.In addition,elemental analyses,X-ray photoelectron spectra(XPS),Fourier transform infrared spectra(FT-IR),and CO_(2) temperature-programmed desorption(CO_(2)-TPD)show that the material has a high nitrogen content(17.8 wt%)with nitrogen-containing groups and abundant basic sites.The hierarchical porous CN spheres have excellent CO_(2) capture properties with a capacity of 2.90 mmol/g at 25℃and 0.97 mmol/g at 75℃,superior to those of the pure carbon materials with analogous mesostructures.This can be mainly attributed to the abundant nitrogen-containing basic groups,hierarchical mesostructure,relatively high BET surface area and stable framework.Furthermore,the presence of a large number of micropores and small mesopores also enhance the CO_(2) capture performance,owing to the capillary condensation effect.Qiang Li Jianping Yang Dan Feng Zhangxiong Wu Qingling Wu Sung Soo Park Chang-Sik Ha Dongyuan Zhao 2010Nano Research2010,3,9:24
3Efficacy and safety of metformin and sitagliptin based triple antihyperglycemic therapy(STRATEGY):a multicenter,randomized,controlled,non-inferiority clinical trial显示文摘Despite the current guideline's recommendation of a timely stepwise intensification therapy,the 'clinical inertia',termed as the delayed treatment intensification,commonly exists in the real world,which may be partly due to the relatively little substantial evidence and no clear consensus regarding the efficacy and safety of triple oral agents in patients inadequately controlled with dual therapy.In this clinical trial performed in 237 centers in China,5,535 type 2 diabetic patients inadequately controlled by previous therapies were treated with a stable metformin/sitagliptin dual therapy for 20 weeks.The patients who did not reach the glycated hemoglobin A1c(HbA1c) goal were then further randomized into glimepiride,gliclazide,repaglinide,or acarbose group for an additional 24-week triple therapy.A mean HbAlc reduction of 0.85%was observed when sitagliptin was added to the patients inadequately controlled with metformin in 16 weeks.Further HbAlc reductions in the 24-week triple therapy stage were 0.65%in glimepiride group,0.70%in gliclazide group,0.61%in repaglinide group,and 0.45%in acarbose group.The non-inferiority criterion for primary hypotheses was met for gliclazide and repaglinide,but not for acarbose,compared with glimepiride,when added to metformin/sitagliptin dual therapy.The incidences of adverse events(AEs) were 29.2%in the dual therapy stage and30.3%in the triple therapy stage.Metformin/sitagliptin as baseline therapy,with the addition of a third oral antihyperglycemic agent,including glimepiride,gliclazide,repaglinide,or acarbose,was effective,safe and well-tolerated for achieving an HbAlc<7.0%goal in type 2 diabetic patients inadequately controlled with previous therapies.The timely augmentation of up to three oral antihyperglycemic agents is valid and of important clinical benefit to prevent patients from exposure to unnecessarily prolonged hyperglycemia.Wen Xu Yiming Mu Jiajun Zhao Dalong Zhu Qiuhe Ji Zhiguang Zhou Bin Yao Anhua Mao Samuel S.Engel Bin Zhao Yan Bi Longyi Zeng Xingwu Ran Juming Lu Linong Ji Wenying Yang Weiping Jia Jianping Weng 2017Science China(Life Sciences)2017,60,3:19
4A review of ecological restoration techniques in fluvial rivers显示文摘Rivers play an important role in people's living and agricultural production,however,intense human activities have broken the original ecological balance,and affected structures and functions of the river ecosystem.To restore the damaged river ecosystem back to a healthy status,effective ecological restoration measures need to be implemented.The main problems that the damaged rivers face are either the locally altered hydrological processes affected by construction of hydraulic facilities,or the deterioration of water quality resulted from pollution emissions,or both.In this study,ecological restoration techniques of the rivers affected by engineering control or pollution are reviewed respectively.In addition,three kinds of methods,i.e.physical,chemical and biological-ecological methods are introduced in details for the rivers affected by water pollution.At present,the development of river restoration techniques shows the following trends:1) the scale of ecological restoration is becoming larger;2) ecological restoration measures are required to meet multiple objectives;and 3) the management of water environment is changing from water quality management to aquatic ecosystem management.Baozhu Pan Jianping Yuan Xinhua Zhang Zhaoyin Wang Jiao Chen Jinyou Lu Wenjun Yang Zhiwei Li Na Zhao Mengzhen Xu 2016International Journal of Sediment Research2016,31,2:18
5Combination of western medicine and Chinese traditional patent medicine in treating a family case of COVID-19显示文摘In December 2019,an outbreak of novel coronavirus(2019-nCoV)occurred in Wuhan,Hubei Province,China.By February 14,2020,it has led to 66492 confirmed patients in China and high mortality up to^2.96%(1123/37914)in Wuhan.Here we report the first family case of coronavirus disease 2019(COVID-19)confirmed in Wuhan and treated using the combination of western medicine and Chinese traditional patent medicine Shuanghuanglian oral liquid(SHL).This report describes the identification,diagnosis,clinical course,and management of three cases from a family,suggests the expected therapeutic effects of SHL on COVID-19,and warrants further clinical trials.Li Ni Ling Zhou Min Zhou Jianping Zhao Dao Wen Wang 2020Frontiers of Medicine2020,14,2:15
6QUADRATIC OPTIMIZATION METHOD AND ITS APPLICATION ON OPTIMIZING MECHANISM PARAMETER显示文摘以便设计的机制与最佳的动力学行为满足 kinematics 的要求,一个二次的优化方法基于运动学、动态的优化的不同特征被建议。这个方法包括优化的二步,也就是说运动学、动态的优化。同时,它把运动学的优化的结果用作动态优化的限制方程。这个方法在与显著意义与 high-speedrice 幼苗 transplanter 的椭圆形的行星的齿轮移植机制的参数优化被使用。参数光谱,相遇到运动学的要求,在 kinematics 优化通过设想的人机相互作用被获得,并且最佳的参数在动态优化基于改进基因算法被获得。在动态优化,客观功能作为 theoptimal1 被选动态行为,限制方程从运动学的优化的结果。当两个都运动学、动态的表演充当客观功能时,这个方法对多客观的优化合适。ZHAO Yun CHEN Jianneng YU Yaxin YU Gaohong ZHU Jianping 2006Chinese Journal of Mechanical Engineering2006,19,4:14
7Preparation and Characterization of Three Monoclonal Antibodies against HIV-1 p24 Capsid Protein显示文摘HIV-1 p24 detection provides a means to aid the early diagnosis of HIV-1 infection, track the progression of disease and assess the efficacy of antiretroviral therapy. In the present study, three monoclonal antibodies (mAbs) p3JB9, p5F1 and p6F4 against HIV-1 p24 were generated. All mAbs could detect p24 of HIV-1IIIB, HIV-1Ada-M, HIV-174V mAbs p5F1 and p6F4 could detect HIV-1KM018, while p3JB9 could not. Three mAbs did not react with HIV-2ROD, HIV-2CBL-20 and SIVagmTYO-1. The recognized epitope of p5F1 was located on the Gag amino acid region DCKTILKALGPAATLEEMMTAC. The p5F1 was used to establish a modified sandwich ELISA with rabbit anti-p24 serum and showed good specificity and high sensitivity, which has been used to measure HIV-1 p24 antigen levels in research.Guangjie Liu Jianping Wang Jianchun Xiao Zhiwei Zhao Yongtang Zheng 2007Cellular & Molecular Immunology2007,4,3:14

9Application of wavelet transform in feature extraction and pattern recognition of wideband echoes显示文摘A novel approach to extract edge features from wideband echo is proposed. The set of extracted features not only represents the echo waveform in a concise way, but also is sufficient and well suited for classification of non-stationary echo data from objects with different property.The feature extraction is derived from the Discrete Dyadic Wavlet Transform (DDWT) of the echo through the undecimated algorithm. The motivation we use the DDWT is that it is time-shift-invariant which is beneficial for localization of edge, and the wavelet coefficients at larger scale represent the main shape feature of echo, i.e. edge, and the noise and modulated high-frequency components are reduced with scale increased. Some experimental results using real data which contain 144 samples from 4 classes of lake bottoms with different sediments are provided. The results show that our approach is a prospective way to represent wideband echo for reliable recognition of nonstationary echo with great variability.ZHAO Jianping HUANG Jianguo ZHANG Huafeng(College of Marine Engineering, Northwestern Polytechnical University Xi’an 710072) 1998Chinese Journal of Acoustics1998,17,3:8
10Middle-Late Pleistocene Glacial Lakes in the Grand Canyon of the Tsangpo River,Tibet显示文摘Many moraines formed between Daduka and Chibai in the Tsangpo River valley since Middle Pleistocene.A prominent set of lacustrine and alluvial terraces on the valley margin along both the Tsangpo and Nyang Rivers formed during Quaternary glacial epoch demonstrate lakes were created by damming of the river.Research was conducted on the geological environment,contained sediments,spatial distribution,timing,and formation and destruction of these paleolakes.The lacustrine sediments 14C(10537±268 aBP at Linzhi Brick and Tile Factory,22510±580 aBP and 13925±204 aBP at Bengga,21096±1466 aBP at Yusong) and a series of ESR(electron spin resonance) ages at Linzhi town and previous data by other experts,paleolakes persisted for 691~505 kaBP middle Pleistocene ice age,75-40 kaBP the early stage of last glacier,27-8 kaBP Last Glacier Maximum(LGM),existence time of lakes gradually shorten represents glacial scale and dam moraine supply potential gradually cut down,paleolakes and dam scale also gradually diminished.This article calculated the average lacustrine sedimentary rate of Gega paleolake in LGM was 12.5 mm/a,demonstrates Mount Namjagbarwa uplifted strongly at the same time,the sedimentary rate of Gega paleolake is more larger than that of enclosed lakes of plateau inland shows the climatic variation of Mount Namjagbarwa is more larger and plateau margin uplifted more quicker than plateau inland.This article analyzed formation and decay cause about the Zelunglung glacier on the west flank of Mount Namjagbarwa got into the Tsangpo River valley and blocked it for tectonic and climatic factors.There is a site of blocking the valley from Gega to Chibai.This article according to moraines and lacustrine sediments yielded paleolakes scale:the lowest lake base altitude 2850 m,the highest lake surface altitude 3585 m,3240 m and 3180 m,area 2885 km2,820 km2 and 810 km2,lake maximum depth of 735 m,390 m and 330 m.We disclose the reason that previous experts discovered there were different age moraines dividing line of altitude 3180 m at the entrance of the Tsangpo Grand Canyon is dammed lake erosive decay under altitude 3180 m moraines in the last glacier era covering moraines in the early ice age of late Pleistocene,top 3180 m in the last glacier moraine remained because ancient dammed lakes didn't erode it under 3180 m moraines in the early ice age of late Pleistocene exposed.The reason of the top elevation 3585 m moraines in the middle Pleistocene ice age likes that of altitude 3180 m.There were three times dammed lakes by glacier blocking the Tsangpo River during Quaternary glacial period.During other glacial and interglacial period the Zelunglung glacier often extended the valley but moraine supplemental speed of the dam was smaller than that of fluvial erosion and moraine movement,dam quickly disappeared and didn't form stable lake.ZHU Song WU Zhenhan ZHAO Xitao LI Jianping WANG Hua 2012Acta Geologica Sinica(English Edition)2012,86,1:8
11Biomimetic thiamine- and niacin-decorated liposomes for enhanced oral delivery of insulin显示文摘Biomimetic nanocarriers are emerging as efficient vehicles to facilitate dietary absorption of biomacromolecules. In this study, two vitamins, thiamine and niacin, are employed to decorate liposomes loaded with insulin, thus facilitating oral absorption via vitamin ligand–receptor interactions. Both vitamins are conjugated with stearamine, which works to anchor the ligands to the surface of liposomes.Liposomes prepared under optimum conditions have a mean particle size of 125–150 nm and an insulin entrapment efficiency of approximately 30%–36%. Encapsulation into liposomes helps to stabilize insulin due to improved resistance against enzymatic disruption, with 60% and 80% of the insulin left after 4 h when incubated in simulated gastric and intestinal fluids, respectively, whereas non-encapsulated insulin is broken down completely at 0.5 h. Preservation of insulin bioactivity against preparative stresses is validated by intra-peritoneal injection of insulin after release from various liposomes using the surfactant Triton X-100. In a diabetic rat model chemically induced by streptozotocin, both thiamine-and niacindecorated liposomes showed a comparable and sustained mild hypoglycemic effect. The superiority of decorated liposomes over conventional liposomes highlights the contribution of vitamin ligands. It is concluded that decoration of liposomes with thiamine or niacin facilitates interactions with gastrointestinal vitamin receptors and thereby facilitates oral absorption of insulin-loaded liposomes.Haisheng He Yi Lu Jianping Qi Weili Zhao Xiaochun Dong Wei Wu 2018Acta Pharmaceutica Sinica B2018,8,1:8
12Regional eco-efficiency evaluation and spatial pattern analysis of the Yangtze River Economic Zone显示文摘The environmental ecology of the Yangtze River Economic Zone(YREZ)faces ecological function decline,deterioration and degradation under intense human activities,long-term development and utilization and its economy has developed rapidly over recent decades.Eco-efficiency is considered as a measure of coordinated development of economy,resources,environment and ecology,and is currently considered a very important issue.In this paper,based on the slack-based measure and data envelope analysis model,we take 129 prefecture-level cities of the YREZ as the study unit and measure the eco-efficiency of the YREZ in 2000,2005,2010 and 2015,which considers undesired output.The evaluation of the status quo of the regional eco-efficiency development was carried out at provincial,prefectural and city scales.The spatial autocorrelation test model and standard deviation ellipse were used to analyze the spatially distributed characteristics and the evolutionary regularity of eco-efficiency.Our study suggested that the eco-efficiency value varied significantly at different spatiotemporal scales and the overall distribution presented an'N-shaped'pattern,the value is the largest downstream and the smallest upstream.Regional eco-efficiency presented certain volatility in growth and a clear spatial positive agglomeration trend from 2000 to 2015.The spatial distribution of each agglomeration area was also significantly different,forming some high-high agglomeration areas at the center of the shaft with Shanghai and surrounding cities,and some low-low agglomeration areas at the center with middle reaches and upstream cities.The low-high over-aggregation and high-low polarization clusters were fewer.At the same time,with the change of the research period,the degree of positive agglomeration became increasingly pronounced and the eco-efficiency gap of the neighborhoodunit reduced.The regional eco-efficiency value of the YREZ presented a spatial distribution pattern in the northeast-southwest axis and the evolutionary pattern of the regional eco-efficiency similarly showed a northeast-southwest orientation.HA Lin TU Jianjun YANG Jianping XU Chunhai PANG Jiaxing LU Debin YAO Zuolin ZHAO Wenyu 2020Journal of Geographical Sciences2020,30,7:8
13A discussion on the upper limit of maturity for gas generation by marine kerogens and the utmost of gas generative potential:Taking the study on the Tarim Basin as an example显示文摘The experimental data yielded by Rock-Eval pyrolysis, kerogen atomic H/C, Py-GC and gold-tube sealing thermal simulation on the marine Cambrian-Ordovician source rock from the Tarim Basin revealed that the upper limit of maturity for natural gas generation or the 'deadline of gas generation' for marine types I and II kerogens is equal to 3.0% of vitrinite reflectance (Ro); while the 'deadline of gas generation' for type III kerogens typically like coals is as high as 10% Ro. Thus, different organic matter has obviously different utmost maturities for gas generation. The mass-balance calculation by kerogen elements showed that when Ro>1.5%, the utmost amount of gas generation for the marine type II kerogen is less than 185 m3/t TOC, accounting for less than 30% of its total hydrocarbon generative potential; when Ro>2.0%, it becomes 110 m3/t TOC, less than 20% of the total hydrocarbon generative potential. The amount of the gas generative potential obtained by Rock-Eval is only around one tenth of the calculated value by the mass balance of kerogen elements at the same thermal evolutionary stage, while those by Py-GC and gold-tube sealing simulation are intervenient between the above two. The utmost of gas generative potential at the over 1.3% Ro stage is around 60―90 m3/t TOC, therefore, the amount of gas generation obtained by Rock-Eval is the minimum of gas generative potential, while that by the mass-balance calculation of kerogen elements is the maximum that the actual amount of gas generation should not exceed.CHEN JianPing ZHAO WenZhi XIAO ZhongYao ZHANG ShuiChang DENG ChunPing SUN YongGe WANG ZhaoMing 2007Chinese Science Bulletin2007,52,A01:8
14Subduction-zone peridotites and their records of crust-mantle interaction显示文摘Subduction is the core process of plate tectonics. The mantle wedge in subduction-zone systems represents a key tectonic unit, playing a significant role in material cycling and energy exchange between Earth's layers. This study summarizes research progresses in terms of subduction-related peridotite massifs, including supra-subduction zone(SSZ) ophiolites and mantle-wedge-type(MWT) orogenic peridotites. We also provide the relevant key scientific questions that need be solved in the future. The mantle sections of SSZ ophiolites and MWT orogenic peridotites represent the mantle fragments from oceanic and continental lithosphere in subduction zones, respectively. They are essential targets to study the crust-mantle interaction in subduction zones. The nature of this interaction is the complex chemical exchanges between the subducting slab and the mantle wedge under the major control of physical processes. The SSZ ophiolites can record melt/fluid-rock interaction, metamorphism,deformation, concentration of metallogenic elements and material exchange between crust and mantle, during the stages from the generation of oceanic lithosphere at spreading centers to the initiation, development, maturation and ending of oceanic subduction at continental margins. The MWT orogenic peridotites reveal the history of strong metamorphism and deformation during subduction, the multiple melt/fluid metasomatism(including silicatic melts, carbonatitic melts and silicate-bearing C-HO fluids/supercritical fluids), and the complex cycling of crust-mantle materials, during the subduction/collision and exhumation of continental plates. In order to further reveal the crust-mantle interaction using subduction-zone peridotites, it is necessary to utilize high-spatial-resolution and high-precision techniques to constrain the complex chemical metasomatism, metamorphism,deformation at micro scales, and to reveal their connections with spatial-temporal evolution in macro-scale tectonics.Jianping ZHENG Qing XIONG Yi ZHAO Wenbo LI 2019Science China Earth Sciences2019,62,7:8
15Content analysis of systematic reviews on effectiveness ofTraditional Chinese Medicine显示文摘OBJECTIVE:To evaluate evidence for the efficacy of Traditional Chinese Medicine(TCM) in systematic reviews.METHODS:Chinese(TCM Periodical Literature Database,Chinese Biological Medicine database,Chinese Medical Current Contents,China Hospital Knowledge Database journal fulltext database,Virtual Machining and Inspection System,and Wanfang) and English(Cochrane Database of Systematic Reviews,PubMed and Embase) databases were searched.RESULTS:Three thousand,nine hundred and fifty-five articles were initially identified,606 of which met the inclusion criteria,including 251 in English(83 from the Cochrane Database) and 355 in Chinese.The number of articles published each year increased between 1989 and 2009.Cardiocerebrovascular disease was the most studied target disease.Intervention measures included TCM preparations(177 articles),acupuncture(133 articles) and combinations of TCM and Western Medicine(38 articles).Control measures included positive medical(177 articles),basic treatment(100 articles),placebo(219 articles),and blank and mutual(107 articles).All articles included at least one reference;the greatest number was 268.Six of 10 articles with high quality references demonstrated curative effectsagainst target diseases including upper respiratory tract infection,dementia and depression.Interventions that were not recommended were tripterygium for rheumatoid arthritis and TCM syndrome differentiation for pediatric nocturia.In 10.4% of the studies,the authors concluded that the intervention had a curative effect.The assessors agreed with the authors' conclusions in 88.32% of cases,but rejected 8.94%(54 articles).CONCLUSION:1) Training in systematic review methods,including topic selection,study design,methods and technology,should be improved.2) Upper respiratory tract infection,dementia and depression may become the predominant diseases treated by TCM,and the corresponding interventions could be developed into practical applications.3) Use of non-recommended interventions should be controlled,and there should be more research on side effects.Junwen Wang Meng Cui Hongguan Jiao Yuanyuan Tong Jun Xu Yingkai Zhao Mei Han Jianping Liu 2013Journal of Traditional Chinese Medicine2013,33,2:7
16An Overview of Mineral Dust Modeling over East Asia显示文摘East Asian dust(EAD) exerts considerable impacts on the energy balance and climate/climate change of the earth system through its influence on solar and terrestrial radiation, cloud properties, and precipitation efficiency. Providing an accurate description of the life cycle and climate effects of EAD is therefore critical to better understanding of climate change and socioeconomic development in East Asia and even worldwide. Dust modeling has undergone substantial development since the late 1990 s, associated with improved understanding of the role of EAD in the earth system. Here, we review the achievements and progress made in recent decades in terms of dust modeling research,including dust emissions, long-range transport, radiative forcing(RF), and climate effects of dust particles over East Asia. Numerous efforts in dust/EAD modeling have been directed towards furnishing more sophisticated physical and chemical processes into the models on higher spatial resolutions. Meanwhile, more systematic observations and more advanced retrieval methods for instruments that address EAD related science issues have made it possible to evaluate model results and quantify the role of EAD in the earth system, and to further reduce the uncertainties in EAD simulations. Though much progress has been made, large discrepancies and knowledge gaps still exist among EAD simulations. The deficiencies and limitations that pertain to the performance of the EAD simulations referred to in the present study are also discussed.Siyu CHEN Jianping HUANG Yun QIAN Chun ZHAO Litai KANG Ben YANG Yong WANG Yuzhi LIU Tiangang YUAN Tianhe WANG Xiaojun MA Guolong ZHANG 2017Journal of Meteorological Research2017,31,4:7
1716 × 16 silicon Mach–Zehnder interferometer switch actuated with waveguide microheaters显示文摘We experimentally demonstrate a 16 × 16 reconfigurably nonblocking optical switch fabric using a Benes architecture. The switch fabric consists of 56 2 × 2 Mach–Zehnder interferometer based elementary switches, with each integrated with a pair of waveguide microheaters. The average on-chip insertion loss is ~5.2 dB for both of the 'all-cross' and the 'all-bar' states, with a loss variation of 1 dB over all routing paths. The cross talk for all switching states is better than -30 d B. The switching time of the switch element is about 22 μs. The switching functionality is verified by transmission of a 40 Gb∕s quadrature phase-shift keying optical signal.Shuoyi Zhao Liangjun Lu Linjie Zhou Dong Li Zhanzhi Guo Jianping Chen 2016Photonics Research2016,4,5:7
18Reduning injection for fever, rash, and ulcers in children with mild hand, foot, and mouth disease: a randomized controlled clinical study显示文摘OBJECTIVE: To assess the efficacy and safety of Reduning injection for fever, rash, and ulcers in children with mild hand, foot, and mouth disease(HFMD). METHODS: A stratified-block randomized, double-blind, parallel-controlled, and multicenter clinical trial was conducted with 360 patients in five hospitals across China: Quanzhou Children's Hospital, Shijiazhuang No. 5 Hospital, Shanghai Public Health Centre, Hunan Provincial Children's Hospital, and Kaifeng Children's Hospital. Patients were randomized into three groups with 120 in each. Group A was treated with Western Medicine, group B with Reduning injection, a Chinese herbal medicine, and group C with both Reduning injection and Western Medicine. Results were compared for treatment efficacy and safety on HFMD. The clinical outcomes were observed as follows: fever and onset time of antifebrile effect(time to bring the body temperature down ≥0.5℃ after medication); cumulative time for fever recovery(body temperature recovering to normal and lasting more than 24 h without medication); cumulative time for rash disappearance(without new rashes or ulcers appearing and the original ones fading away); and cumulative time for mouth ulcer disappearance. RESULTS: For the onset time of the antifebrile effect, there was no statistical difference between groups A and B(P>0.05) and groups B and C(P> 0.05). However, there was a statistical difference between groups A and C(P<0.05), and the effect in group C was the best. For the cumulative time for rash disappearance, there was no statistical difference between groups A and B(P>0.05). There were statistical differences between groups A and C, and groups B and C(P<0.05), and the effect in group C was the best. For the cumulative time for mouth ulcers disappearance, there were no statistical differences among the three groups(P>0.05). CONCLUSION: Reduning injection with Western Medicine for symptomatic treatment is most effective for mild HFMD. No adverse reactions were observed.Guoliang Zhang Jie Zhao Liyun He Shiyan Yan Ziqiang Zhuo Haojie Zheng Yongping Mu Shuangjie Li Xi Zhang Jihan Huang Xiuhui Li Jianping Liu Hehe Wan Chaoyu Wei Wei Xiao 2013Journal of Traditional Chinese Medicine2013,33,6:7
19Aerosol characteristics and impacts on weather and climate over the Tibetan Plateau显示文摘With themostmassive snow and ice globally between 60°S and 60°S ,the Tibetan Plateau(TP),also called the third pole of the world,plays significant roles in the weather,climate and lives in South Asia and East Asia and even the world[1–3].Investigating the variation of weather and the climate system over the TP has long been carried out,which is significant for fresh water supplies for over 1.4 billion people in Asia.Actually,the‘Third Pole Environment’program was initiated to call international efforts to understand both climate and environment changes on the plateau[1],which has already shown rapid warming and intensified cryospheric melt and water cycle.Chuanfeng Zhao Yikun Yang Hao Fan Jianping Huang Yunfei Fu Xiaoye Zhang Shichang Kang Zhiyuan Cong Husi Letu Massimo Menenti 2020National Science Review2020,7,3:7
20The recent advances in self-powered medical information sensors显示文摘Monitoring various medical information distributed throughout the body is of great importance in early clinic diagnosis and treatment of disease.To discover abnormal medical signals and find their causes in good time,the human body should be monitored continuously and accurately.To meet the requirements,various battery-less and self-powered information acquisition techniques are invented.In this review,the recent advances in self-powered medical information sensors(SMIS)with different functions,structure design,and electric performance are summarized and discussed.The SMIS mainly involves triboelectric nanogenerator(TENG),piezoelectric nanogenerator(PENG),pyroelectric nanogenerator(PyNG)/thermoelectric generator(TEG)and solar cell.Additionally,this review also analyzed the remaining challenges and prospected the development direction of SMIS in future.Luming Zhao HuLi Jianping Meng Zhou Li 2020InfoMat2020,2,1:7
