| 1 | Heat-sensitive moxibustion for lumbar disc herniation:a meta-analysis of randomized controlled trials显示文摘OBJECTIVE:To assess the efficacy and safety of heat-sensitive moxibustion in the treatment of lumbar disc herniation(LDH).METHODS:Randomized controlled trials(RCTs) involving heat-sensitive moxibustion in the treatment of LDH were retrieved from the Chinese Biological Medical Literature database(1978-20011),Weipu database(1989-2011),Wanfang digital journal(1998-2011),China National Knowledge Internet(1979-2011),PubMed(1966-2011),EMBASE(1980-2011),and Cochrane Library(Issue 1,2011).Hand-search of the relevant journals from the Library of Jiangxi University of Traditional Chinese Medicine was also adopted for the collection of data.Data were extracted and evaluated by two reviewers independently with a specially designed extraction form.The Cochrane Collaboration's RevMan 5.0.20 software was used for data analyses.RESULTS:A total of 6 trials involving 580 patients were included.Meta-analysis showed that the total effectiveness rate in the heat-sensitive moxibustion group was significantly different when compared with conventional moxibustion [RR=1.19,95% CI [1.06,1.33)] and diclofenac sodium [RR=1.47,95% CI [1.17,1.85)],but similar to that of acupuncture.The cure rate in the heat-sensitive moxibustion group was significantly different when compared with conventional moxibustion [RR=1.58,95% CI(1.04,2.40)] and diclofenac sodium [RR=1.91,95% CI(1.01,3.60)],but similar with that of acupuncture.In terms of the Japanese Orthopaedic Association scores,significant differences were noted in subjective indices,objective indices,and daily life subscales.Two trials reported that there were no adverse events over the duration of treatment.CONCLUSION:Compared with conventional moxibustion,acupuncture,and diclofenac sodium,heat-sensitive moxibustion in the treatment of LDH is superior in efficacy.Further large-scale trials are required to define the role of heat-sensitive moxibustion in the treatment of this disease. | Rixin Chen Jun Xiong Zhenhai Chi Bo Zhang | 2012 | Journal of Traditional Chinese Medicine2012，32，3： | 33 |
| 2 | Distribution and genesis of the anomalously high porosity zones in the middle-shallow horizons of the northern Songliao Basin显示文摘High-quality reservoirs occur in the middle-shallow horizons of the northern Songliao Basin. The distribution and genesis of their anomalously high porosity zones were studied using measured porosities, examination of ordinary thin sections and blue epoxy resin-impregnated thin sections and by SEM. The results show that there are three anomalously high porosity zones at the depth of 450-900 m, 1,300-1,900 m, 2,050-2,350 m respectively, named zone i, zone ii and zone iii from top to bottom. Horizontally, zone i and zone ii are distributed all over the basin except in the Southeastern Uplift, while zone iii is only distributed in the Central Depression. Zone i was formed by meteoric water leaching as well as organic acid dissolution. Zones ii and iii were dominantly formed by organic acid dissolution. Additionally, clay mineral transformation generating H+ and hydrocarbon emplacement retarding the cementation of sandstones are also important for the formation of zones ii and iii. | Meng Yuanlin Liang Hongwei Meng Fanjin Wu Heyong Wang Cheng Xiu Hongwen Zhang Anda Li Yaguang Guo Rixin | 2010 | Petroleum Science2010，7，3： | 29 |
| 3 | Protective effects of Yindanxinnaotong capsule in a rat model of myocardial ischemia/reperfusion injury显示文摘OBJECTIVE: To investigate the effects of Yindanxinnaotong capsule(YDXNTC) and main components compatibility and ratios on myocardium against ischemia/reperfusion injury and the effect's underlying mechanism.METHODS: Myocardial ischemia/reperfusion injury(MIRI) was induced by ischemia for 30 min and reperfusion for 30 min. Electrocardiogram data and coronary flow were recorded, and superoxide dismutase(SOD), malondialdehyde(MDA), lactate dehydrogenase, creatine kinase-MB, cardiac troponin T and I(cT nT, cT n I) and interleukin-1β, interleukin-8,interleukin-18(IL-1β, IL-8, IL-18) in myocardium were measured. Hypoxia/reoxygenation and hydrogen peroxide(H2O2) injury were induced by hypoxia for 3 h/reoxygenation for 2 h, and 100 μM H2O2 for 1 h, respectively, in vitro rat myocardial cells(H9c2). Cell viability, SOD, MDA, cT nT and inflamma-tory factors(IL-1β, IL-8 and IL-18) were determined,and Toll-like receptor 4(TLR-4) expression was measured by western blotting.RESULTS: In the isolated heart experiment, elevated heart function, coronary flow and SOD levels,and decreased MDA levels and inflammatory factors were noted in the YDXNTC, main components and main components compatibility groups. Ventricular tachycardia/ventricular fibrillation occurrence decreased in the ginkgo biloba extract(GBE),and GBE and salvia miltiorrhiza ethanol extract compatibility(SM-E, GSEC) groups. Lactic dehydrogenase levels decreased in the YDXNTC and aqueous extract of salvia miltiorrhiza(SM-H) groups. Creatine kinase-MB decreased with GBE, SM-E, SM-H and GSEC treatment, and cT n I and cT nT levels decreased with GSEC. In the in vitro cell study,YDXNTC and main components ratios improved cell viability and SOD levels, and suppressed MDA,cT nT and inflammatory factors. TLR-4 expression was down-regulated.CONCLUSION: YDXNTC and main components compatibility showed protective effects on MIRI in this rat model and in vitro study. Regulating the Toll-like receptor signaling pathway may affect the mechanism. | Wandan Wang Lan Wang Hongjun Yang Jianlu Wang Xiaojie Yin Haiyu Xu Long Cheng Rixin Liang | 2014 | Journal of Traditional Chinese Medicine2014，34，6： | 22 |
| 4 | Satellite range scheduling with the priority constraint: An improved genetic algorithm using a station ID encoding method显示文摘Satellite range scheduling with the priority constraint is one of the most important problems in the field of satellite operation.This paper proposes a station coding based genetic algorithm to solve this problem,which adopts a new chromosome encoding method that arranges tasks according to the ground station ID.The new encoding method contributes to reducing the complexity in conflict checking and resolving,and helps to improve the ability to find optimal resolutions.Three different selection operators are designed to match the new encoding strategy,namely random selection,greedy selection,and roulette selection.To demonstrate the benefits of the improved genetic algorithm,a basic genetic algorithm is designed in which two cross operators are presented,a single-point crossover and a multi-point crossover.For the purpose of algorithm test and analysis,a problem-generating program is designed,which can simulate problems by modeling features encountered in real-world problems.Based on the problem generator,computational results and analysis are made and illustrated for the scheduling of multiple ground stations. | Li Yuqing Wang Rixin Liu Yu Xu Minqiang | 2015 | Chinese Journal of Aeronautics2015，28，3： | 22 |
| 5 | Curative effect of heat-sensitive moxibustion on chronic persistent asthma: a multicenter randomized controlled trial显示文摘OBJECTIVE:To compare the curative effects of heat-sensitive moxibustion with conventional drugs on chronic persistent asthma and seek a valuable therapy to replaceWestern Medicine.METHODS:The participants in this multi-center,randomized,and controlled study were randomly divided into two groups:group A(n=144),treated with heat-sensitive moxibustion(50 sessions)and group B(n=144),treated with Seretide(salmeterol50μg/fluticasone 250μg,twice a day).The scores of asthma control test(ACT),forced expiratory volume in 1 second(FEV1),peak expiratory flow(PEF),and attack frequency were measured after 15,30,60,and 90 days of treatment.Patients followed up3 and 6 months after treatment.RESULTS:There was a significant difference(P=0.0002)in the ACT score and lung function between the two groups after 3 months of treatment and(P=0.000 03)during the follow-up visits.In addition,heat-sensitive moxibustion reduced attack frequency in the period from inclusion to the6-month follow-up visit.CONCLUSION:This study shows that heat-sensitive moxibustion may have a comparable curative effect toSeretide(salmeterol/fluticasone)on asthma. | Rixin Chen Mingren Chen Jun Xiong Zhenhai Chi B0 Zhang Ning Tian Zhenhua Xu Tangfa Zhang Wanyao Li Wei Zhang Xiaofeng Rong Zhen Wang Gang Sun Baohe Ge Guoxiong Yu Nanchang Song | 2013 | Journal of Traditional Chinese Medicine2013，33，5： | 20 |
| 6 | Rescheduling of observing spacecraft using fuzzy neural network and ant colony algorithm显示文摘This paper aims at rescheduling of observing spacecraft imaging plans under uncertainties. Firstly, uncertainties in spacecraft observation scheduling are analyzed. Then, considering the uncertainties with fuzzy features, this paper proposes a fuzzy neural network and a hybrid rescheduling policy to deal with them. It then establishes a mathematical model and manages to solve the rescheduling problem by proposing an ant colony algorithm, which introduces an adaptive control mechanism and takes advantage of the information in an existing schedule. Finally, the above method is applied to solve the rescheduling problem of a certain type of earth-observing satellite.The computation of the example shows that the approach is feasible and effective in dealing with uncertainties in spacecraft observation scheduling. The approach designed here can be useful in solving the problem that the original schedule is contaminated by disturbances. | Li Yuqing Wang Rixin Xu Minqiang | 2014 | Chinese Journal of Aeronautics2014，27，3： | 19 |
| 7 | Efficacy of suspended moxibustion in stroke rats is associated with a change in tail temperature显示文摘Suspended moxibustion-produced heat can transfer from the acupoint to other sites of the body. The suspended moxibustion should be terminated when clinical propagated sensation disappears, because this implies that the quantity of moxibustion is sufficient. We wanted to investigate if this phenomenon also occurs in experimental animals. In the present study, a rat model of stroke was established and treated with suspended moxibustion at Dazhui (DU14) for 60 minutes. Results showed that the increase in tail temperature began at 15 minutes after suspended moxibustion and decreased gradually at 40 minutes. In addition, neurological function was significantly improved in stroke rats with tail temperature increase following suspended moxibustion, and this effect was associated with significantly reduced tumor necrosis factor α and interleukin 1β mRNA. However, there was no significant difference between 40-and 60-minute suspended moxibustion. The findings indicate that elevated tail temperature began to decrease at 40 minutes after suspended moxibustion, and further suspended moxibustion was not useful in the recovery of stroke rats. | Rixin Chen Zhimai Lv Dangdang Huang Mingren Chen Fan Yi | 2013 | Neural Regeneration Research2013，8，12： | 11 |
| 8 | Effectiveness and safety of heat-sensitive moxibustion on bronchial asthma:a Meta-analysis of randomized control trials显示文摘OBJECTIVE: To systematically evaluate the effectiveness and safety of heat-sensitive moxibustion(HSM)onasthma.METHODS: Large databases in China and overseas were searched by electronic and manual means to collect information on randomized controlled trials(RCTs).Two evaluators independently extracted data and evaluated the quality of RCTs according to Cochrane Review Handbook v5.0. RevMan v5.0.20 was used for statisticalanalyses.RESULTS: Fourteen RCTs involving 637 patients were collected.Thirteen RCTs compared the effects of HSM and Western Medicine. After 3-month treatment and after 6-month follow-up, there was no significant difference in effective rate [relative risk(RR)=1.01, 95% CI(0.92, 1.12), and 1.12,(0.93, 1.36),respectively], in the asthma control test score of asthma symptoms [weighted mean difference(WMD)=﹣1.54, 95% CI(﹣3.54, 0.47), and 1.41,(﹣0.48, 3.29), respectively] and in the forced expiratory volumein 1 second(FEV1)and peak expiratory flow(PEF). One RCT compared the effect of HSM with warm-suspended moxibustion. After 6-month follow-up, there was a significant difference in FEV1 and PEF [WMD=0.51, 95% CI(0.10, 0.92), and 1.78,(1.06, 2.50), respectively]. After 3-month treatment,there was no significant difference between the two groups. One RCT compared the effect of HSM with acupoint application. After 3-month treatment, there was no significant difference in the effectiverate[RR=0.68,95%CI(0.42,1.12)].CONCLUSION: HSM did not show superiority to conventional Western Medicine and acupoint application in terms of curative effects, and may be superior to warm-suspended moxibustion with regard to long-term curative effects. Because of low quality of the included RCTs, this conclusion must be bolstered with higher-quality RCTs. | Jun Xiong Zhongyong Liu Rixin Chen Dingyi Xie Zhenhai Chi Bo Zhang | 2014 | Journal of Traditional Chinese Medicine2014，34，4： | 11 |
| 9 | Heat-sensitive moxibustion attenuates the inflammation after focal cerebral ischemia/ reperfusion injury显示文摘Heat-sensitive moxibustion has neuroprotective effects against focal cerebral ischemia/reperfusion injury, however its mechanism of action remains unclear. In this study, rat models of focal cerebral ischemia/reperfusion injury were treated with suspended moxibustion at acupoint Dazhui (DU14) for 35 minutes. Results showed that suspended moxibustion decreased infarct volume, reduced cortical myeloperoxidase activity, and suppressed serum levels of proinflammatory cytokines in rats with focal cerebral ischemia/reperfusion injury. Our experimental findings indicated that heat-sensitive moxibustion can attenuate inflammation and promote repair after focal cerebral ischemia/reperfusion injury. | Aijiao Xiao Rixin Chen: Mingfei Kang Shenghai Tan | 2012 | Neural Regeneration Research2012，7，33： | 10 |
| 10 | Simultaneous state and actuator fault estimation for satellite attitude control systems显示文摘In this paper,a new nonlinear augmented observer is proposed and applied to satellite attitude control systems.The observer can estimate system state and actuator fault simultaneously.It can enhance the performances of rapidly-varying faults estimation.Only original system matrices are adopted in the parameter design.The considered faults can be unbounded,and the proposed augmented observer can estimate a large class of faults.Systems without disturbances and the fault whose finite times derivatives are zero piecewise are initially considered,followed by a discussion of a general situation where the system is subject to disturbances and the finite times derivatives of the faults are not null but bounded.For the considered nonlinear system,convergence conditions of the observer are provided and the stability analysis is performed using Lyapunov direct method.Then a feasible algorithm is explored to compute the observer parameters using linear matrix inequalities(LMIs).Finally,the effectiveness of the proposed approach is illustrated by considering an example of a closed-loop satellite attitude control system.The simulation results show satisfactory performance in estimating states and actuator faults.It also shows that multiple faults can be estimated successfully. | Cheng Yao Wang Rixin Xu Minqiang Li Yuqing | 2016 | Chinese Journal of Aeronautics2016，29，3： | 9 |
| 11 | Anti-breast cancer effects and mechanisms of Xihuang pill on human breast cancer cell lines显示文摘OBJECTIVE: To investigate the anti-breast cancer(BC) effects and mechanisms of action of Xihuang pill(XHP) by conducting in vitro experiments on human BC cell lines. METHODS: Two human BC cell lines(MCF-7 and MDAMB231) were cultured and treated with XHP. Cell viability was detected using the 3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide(MTT) assay. Flow cytometry was used to measure the cell cycle and apoptosis. The cell cycle was analyzed with propidium iodide staining. Apoptosis was evaluated using the Annexin V-fluorescein isothiocyanate/propidium iodide method. Western blotting was used to analyze the expression of estrogen receptor(ER)-α and ER-β.RESULTS: XHP had growth-inhibitory effects on MCF-7 and MDA-MB231 cells with a half-maximal inhibitory concentration(IC50) of 10.14 mg/mL(MCF-7) and 8.98 mg/mL(MDA-MB231). Apoptosis was induced to some extent. Certain changes in the ER were caused. Upregulation of ER-α protein was found in MCF-7 cells. ER-β expression in MDA-MB231 cells was increased. Cell-cycle arrest was not observed in the two BC cell lines. ER-β expression in MCF-7 cells was unchanged. No ER-α expression was shown in MDA-MB231 cells. CONCLUSION: These data suggest that XHP can affect cell viability and cause apoptosis, but that the cell cycle is not blocked. XHP has a certain impact on ER expression, but its mechanisms of action of anti-BC effects may not be due to regulation of ER expression. | Guofeng Pan Wandan Wang Lan Wang Fangbo Zhang Xiaojie Yin Jianlu Wang Rixin Liang | 2013 | Journal of Traditional Chinese Medicine2013，33，6： | 8 |
| 12 | Image formation of brain function in patients suffering from knee osteoarthritis treated with moxibustion显示文摘OBJECTIVES:Functional magnetic resonance imaging(fMRI) technology was used to study changes to the resting state blood flow in the brains of patients with knee osteoarthritis(KOA) before and after treatment with moxibustion at the acupoint of the left Dubi(ST 35) and to probe the cerebral mechanism underlying the effect of moxibustion.METHODS:The resting state brain function of 30 patients with left KOA was scanned with fMRI before and after treatment with moxibustion.The analytic methods of fractional amplitude of low frequency fluctuation(fALFF) and regional homogeneity(ReHo) were used to observe changes in resting state brain function.RESULTS:The fALFF values of the right cerebrum,extra-nucleus,left cerebellum,left cerebrum and white matter of patients after moxibustion treatment were higher than before treatment,and the fALFF values of the precentral gyrus,frontal lobe and occipital lobe were lower than before treatment(P<0.05,K≥85).The ReHo values of the thalamus,extra-nucleus and parietal lobe of patients were much higher than those before moxibustion treatment,and the ReHo values of the right cerebrum,left cerebrum and frontal lobe were lower than before treatment(P<0.05,K≥85).CONCLUSION:The influence of moxibustion on obvious changes in brain regions basically conforms to the way that pain and warmth is transmitted in the body,and the activation of sensitive systems in the body may be objective evidence of channel transmission.The regulation of brain function by moxibustion is not in a single brain region but rather in a network of many brain regions. | Hongwu Xie Fangming Xu Rixin Chen Tianyou Luo Mingren Chen Weidong Fang Fajin Lü Fei Wu Yune Song Jun Xiong | 2013 | Journal of Traditional Chinese Medicine2013，33，2： | 7 |
| 13 | Neuronal apoptosis and inflammatory reaction in rat models of focal cerebral ischemia following 40-minute suspended moxibustion显示文摘The treatment duration of heat-sensitive moxibustion(approximately 40 minutes on average) is longer than that of traditional suspended moxibustion.The present study investigated expression changes of three inflammatory and apoptosis-associated proteins(inducible nitric oxide synthase,cyclooxygenase-2 and caspase-3) in transient middle cerebral artery occlusion model rats following suspended moxibustion for 40 minutes,to explore the mechanisms underlying neuroprotective action of suspended moxibustion.The results indicated that suspended moxibustion at acupoint Dazhui(DU 14) for 40 minutes reduced the cortical expression of caspase-3,cyclooxygenase-2 and inducible nitric oxide synthase proteins of transient middle cerebral artery occlusion model rats,as well as decreasing infarct volume and ameliorating the neurological deficit score.Outcomes with 40 minutes of moxibustion were superior to the outcomes after suspended moxibustion for 15 minutes. | Rixin Chen Zhimai Lv Mingren Chen Xin An Dingyi Xie Jing Yi | 2011 | Neural Regeneration Research2011，6，15： | 6 |
| 14 | Human β-defensin 3 gene modification promotes the osteogenic differentiation of human periodontal ligament cells and bone repair in periodontitis显示文摘Efforts to control inflammation and achieve better tissue repair in the treatment of periodontitis have been ongoing for years.Humanβ-defensin 3,a broad-spectrum antimicrobial peptide has been proven to have a variety of biological functions in periodontitis;however,relatively few reports have addressed the effects of human periodontal ligament cells(h PDLCs)on osteogenic differentiation.In this study,we evaluated the osteogenic effects of h PDLCs with an adenoviral vector encoding humanβ-defensin 3 in an inflammatory microenvironment.Then humanβ-defensin 3 gene-modified rat periodontal ligament cells were transplanted into rats with experimental periodontitis to observe their effects on periodontal bone repair.We found that the humanβ-defensin 3 gene-modified h PDLCs presented with high levels of osteogenesis-related gene expression and calcium deposition.Furthermore,the p38 MAPK pathway was activated in this process.In vivo,humanβ-defensin 3 gene-transfected rat PDLCs promoted bone repair in SD rats with periodontitis,and the p38 mitogen-activated protein kinase(MAPK)pathway might also have been involved.These findings demonstrate that humanβ-defensin 3 accelerates osteogenesis and that humanβ-defensin 3 gene modification may offer a potential approach to promote bone repair in patients with periodontitis. | Lingjun Li Han Jiang Rixin Chen Jing Zhou Yin Xiao Yangheng Zhang Fuhua Yan | 2020 | International Journal of Oral Science2020，12，2： | 5 |
| 15 | Model-Based Degree Estimation of Unbalance and Misalignment in Flexible Coupling-rotor System显示文摘The condition of rotor system must be assessed in order to develop condition-based maintenance for rotating machinery. It is determined by multiple variables such as unbalance degree,misalignment degree,the amount of bending deformation of the shaft,occurrence of shaft crack of rotor system and so on. The estimation of the degrees of unbalance and misalignment in flexible coupling-rotor system is discussed. The model-based approach is employed to solve this problem. The models of the equivalent external loads for unbalance and misalignment are derived and analyzed. Then,the degrees of unbalance and misalignment are estimated by analyzing the components of the equivalent external loads of which the frequencies are equal to the 1 and 2 times running frequency respectively. The equivalent external loads are calculated according to the dynamic equation of the original rotor system and the differences between the dynamical responses in normal case and the vibrations when the degree of unbalance or misalignment or both changes. The denoise method based on bandpass filter is used to decrease the effect of noise on the estimation accuracy. The numerical examples are given to show that the proposed approach can estimate the degrees of unbalance and misalignment of the flexible coupling-rotor system accurately. | LI Changyou XU Minqiang GUO Song WANG Yuewu WANG Rixin | 2009 | Chinese Journal of Mechanical Engineering2009，22，4： | 5 |
| 16 | Fault detection of flywheel system based on clustering and principal component analysis显示文摘Considering the nonlinear, multifunctional properties of double-flywheel with closedloop control, a two-step method including clustering and principal component analysis is proposed to detect the two faults in the multifunctional flywheels. At the first step of the proposed algorithm,clustering is taken as feature recognition to check the instructions of ‘‘integrated power and attitude control' system, such as attitude control, energy storage or energy discharge. These commands will ask the flywheel system to work in different operation modes. Therefore, the relationship of parameters in different operations can define the cluster structure of training data. Ordering points to identify the clustering structure(OPTICS) can automatically identify these clusters by the reachability-plot. K-means algorithm can divide the training data into the corresponding operations according to the reachability-plot. Finally, the last step of proposed model is used to define the relationship of parameters in each operation through the principal component analysis(PCA) method.Compared with the PCA model, the proposed approach is capable of identifying the new clusters and learning the new behavior of incoming data. The simulation results show that it can effectively detect the faults in the multifunctional flywheels system. | Wang Rixin Gong Xuebing Xu Minqiang Li Yuqing | 2015 | Chinese Journal of Aeronautics2015，28，6： | 5 |
| 17 | Multi-objective optimization design of airfoil and wing显示文摘To extend available monoobjective optimization methods to multiobjective and multidisciplinary optimization, the construction of a suitable resultant objective function(in deterministic method-DM) or a fitness function(in genetic algorithm-GA) is important. An objective function combination method (OFCM) of constructing such a function for constrained optimization problems is suggested. How to use both deterministic and genetic algorithms to biobjective and bidisciplinary optimal design of high performance airfoils and wings is discussed. Numerical results in both 2D (airfoil) and 3D (wing) cases show that the present method can be used to optimaize different kinds of initial airfoils and wings. The performance of optimized shape is improved significantly. The method is successful and effective. | ZHU Ziqiang FU Hongyan YU Rixin LIU Jie | 2004 | Science China(Technological Sciences)2004，47，1： | 4 |
| 18 | Approach of fault diagnosis based on similarity degree matching distance function显示文摘A new diagnosis method based on the similarity degree matching distance function is proposed.This method solves the problem that the traditional fault diagnosis methods based on transition system model cannot deal with the'special state'which cannot match the target states completely.For evaluating the relationship between the observation and the target states,this paper first defines a new distance function based on the viewpoint of energy to measure the distance between two attribute values.After that,all the distances of the attributes in the state vector are used to synthesize the distance between two states.For calculating the similarity degree between two states,a trend evaluation method is developed.It analyzes the main direction of the trend of the state transfer according to the distances between the observation and each target state and their historical records.Applying the diagnosis method to a primary power subsystem of a satellite,the simulation result shows that it is effective. | WANG RiXin JIN Yang XU MinQiang | 2013 | Science China(Technological Sciences)2013，56，11： | 3 |
