| 1 | Therapeutic effect in patients with coronary heart disease based on information analysis from Traditional Chinese Medicine four diagnostic methods显示文摘OBJECTIVE:To study information gained by Traditional Chinese Medicine(TCM)four diagnostic methods and characteristics of syndrome development before and after treatment in patients with coronary heart disease,and to probe into assessment indexes of therapeutic effects with distinctive TCM features.METHODS:Information from the four diagnostic methods before and after treatment in 100 patients with coronary heart disease was collected using the TCM interrogation scale,a pulse condition instrument,a tongue-face diagnosis instrument,anda voice diagnosis information collection system.Changes in the four diagnostic method results from before and after treatment were analyzed with frequency analysis and t-test methods.RESULTS:Before treatment,deficiency syndrome complicated with hyperactivity of pathogenic factors was most common.After treatment,deficiency syndrome was most common.This change from complex syndromes to single syndromes indicates disease and syndrome alleviation.Frequencies of symptoms gained by interrogation after treatment for syndrome of deficiency of heart-Qi,syndrome of deficiency of heart-Yin,and turbid phlegm syndrome were all less severe than those before treatment.Parameters of face color,color on all sub-regions of tongue,color of tongue fur,septic and greasy fur,and lip color after treatment all had significant changes.After treatment,part of the voice diagnosis parameters in the deficiency of heart-Yin and turbid phlegm syndromes had significant changes,but no significant changes were found in the deficiency of heart-Qi syndrome.CONCLUSION:Use of the TCM four diagnostic methods can provide an effective basis forTCM syndrome diagnosis,observation of development of state of illness,and evaluation of clinical therapeutic effects. | Yiqin Wang Jin Xu Rui Guo Chaoxia Xu Yiming Hao Chunfeng Chen Yijian Hong Xiangqun Xiao Wenjie Xu Jing Hong Zhao Lei | 2014 | Journal of Traditional Chinese Medicine2014，34，1： | 12 |
| 2 | Roles of a sustained activation of NCED3 and the synergistic regulation of ABA biosynthesis and catabolism in ABA signal production in Arabidopsis显示文摘ABA, acting as a stress signal, plays crucial roles in plant resistance to water stress. Because ABA signal production is based on ABA biosynthesis, the regulation of NCED, a key enzyme in the ABA biosynthesis pathway, is normally thought of as the sole factor controlling ABA signal production. Here we demonstrate that ABA catabolism in combination with a synergistic regulation of ABA biosynthesis plays a crucial role in governing ABA signal production. Water stress induced a significant accumulation of ABA, which exhibited different patterns in detached and attached leaves. ABA catabolism followed a temporal trend of exponential decay for both basic and stress ABA, and there was little difference in the catabolic half-lives of basic ABA and stress ABA. Thus, the absolute rate of ABA catabolism, i.e. the amount of ABA catabolized per unit time, increases with increased ABA accumulation. From the dynamic processes of ABA biosynthesis and catabolism, it can be inferred that stress ABA accumulation may be governed by a synergistic regulation of all the steps in the ABA biosynthesis pathway. Moreover, to maintain an elevated level of stress ABA sustained activation of NCED3 should be required. This inference was supported by further findings that the genes encoding major enzymes in the ABA biosynthesis pathway, e.g. NCED3, AAO3 and ABA3 were all activated by water stress, and with ABA accumulation progressing, the expressions of NCED3, AAO3 and ABA3 remained activated. Data on ABA catabolism and gene expression jointly indicate that ABA signal production is controlled by a sustained activation of NCED3 and the synergistic regulation of ABA biosynthesis and catabolism. | REN HuiBo FAN YiJian GAO ZhiHui WEI KaiFa LI GuiFen LIU Jing CHEN Lin LI BingBing HU JianFang JIA WenSuo | 2007 | Chinese Science Bulletin2007，52，4： | 12 |
| 3 | Joint Beamforming Optimization for Reconfigurable Intelligent Surface-Enabled MISO-OFDM Systems显示文摘In this paper,we investigate the reconfigurable intelligent surface(RIS)-enabled multiple-input-single-output orthogonal frequency division multiplexing(MISO-OFDM)system under frequency-selective channels,and propose a low-complexity alternating optimization(AO)based joint beamforming and RIS phase shifts optimization algorithm to maximize the achievable rate.First,with fixed RIS phase shifts,we devise the optimal closedform transmit beamforming vectors corresponding to different subcarriers.Then,with given active beamforming vectors,near-optimal RIS reflection coefficients can be determined efficiently leveraging fractional programming(FP)combined with manifold optimization(MO)or majorization-minimization(MM)framework.Additionally,we also propose a heuristic RIS phase shifts design approach based on the sum of subcarrier gain maximization(SSGM)criterion requiring lower complexity.Numerical results indicate that the proposed MO/MM algorithm can achieve almost the same rate as the upper bound achieved by the semidefinite relaxation(SDR)algorithm,and the proposed SSGM based scheme is only slightly inferior to the upper bound while has much lower complexity.These results demonstrate the effectiveness of the proposed algorithms. | Keming Feng Xiao Li Yu Han Yijian Chen | 2021 | China Communications2021，18，3： | 6 |
| 4 | Microwave propagation in air drilling显示文摘This paper examines the feasibility in air drilling of transmitting down-hole signals by using microwaves. Firstly the basic theory of microwave propagation in the drill-pipe or casing was studied, including power loss, cutoff wavelength, and dust scattering. Theoretical analysis indicates that the microwave propagation distance in a Ф214mm casing can easily reach 5,000 m. When the effect of dust particles is taken into account, the propagation distance decreases to 2,000 m. We conducted both laboratory experiments and field tests in casings commonly used in oilfields. The field tests show that the effective propagation distance of microwave in the casing is about 1,300 m. The experimental results do not match well with theoretical prediction, but are acceptable. In future commercial applications, by applying multiple relay amplifiers, the microwave propagation distance could be long enough for most drilling wells. | Meng Xiaofeng Chen Yijian Zhou Jing Meng Yingfeng | 2010 | Petroleum Science2010，7，3： | 4 |
| 5 | High Potential Columnar Nanocrystalline AlN Films Deposited by RF Reactive Magnetron Sputtering显示文摘Columnar nanocrystalline aluminum nitride(cnc-AlN) thin films with(002) orientation and uniform texture have been deposited successfully on large silicon wafers by RF reactive magnetron sputtering.At the optimum sputtering parameters, the deposited cnc-AlN thin films show a c-axis preferred orientation with a crystallite size of about 28 nm and surface roughness(RMS) of about 1.29 nm. The cnc-AlN thin films were well transparent with an optical band gap about 4.8 e V, and the residual compressive stress and the defect density in the film have been revealed by Ramon spectroscopy. Moreover, piezoelectric performances of the cnc-AlN thin films executed effectively in a film bulk acoustic resonator structure. | Chengzhang Han Da Chen Yaozhong Zhang Dong Xu Yijian Liu Eric Siu-Wai Kong Yafei Zhang | 2012 | Nano-Micro Letters2012，4，1： | 4 |
| 6 | Analyses of an Improved Double-Absorber Absorption Refrigeration System at Low Temperatures显示文摘An auto-cascade absorption refrigeration(ACAR)system could achieve a-60℃ refrigeration temperature by low-grade heat.For an ACAR system,its performance is mainly affected by energy and mass coupling of the auto-cascade processes.A novel ACAR system with double-absorber was proposed to get higher-efficient refrigeration as low as-60℃ in this context,which used R23-R134 a-DMF(N,N-Dimethylformamide)as its working fluids.Theoretical calculation and analyses were conducted under different working conditions.From the calculated results,the new system gained a COP value 20%higher than that of an ACAR system with single-absorber under the same generating,condensing,absorbing and refrigerating temperatures.Compositions of a refrigerant mixture showed key influences on energy and mass coupling of the auto-cascade processes,and an optimal composition of the mixed refrigerants was obtained for the new ACAR system.In addition,it was clearly found that absorbing processes of the new system had great effects on energy and mass coupling of the auto-cascade processes.Based on the difference of absorbing characteristics among R23,R134 a and DMF,the absorbing processes were intensified under the different absorbing pressures.As a result,an optimal matching pressure was obtained for the new ACAR system.Energy and mass coupling of the auto-cascade processes were further optimized,and the highest COP value was obtained.The theoretical analyses showed that performance of the innovative ACAR system could be superior to that of an ACAR system with single-absorber at a refrigeration temperature from -55℃ to -60℃. | HE Yijian CHEN Guangming | 2019 | Journal of Thermal Science2019，28，4： | 3 |
