1Curative 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 2013Journal of Traditional Chinese Medicine2013,33,5:20
2Efficacy 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 2013Neural Regeneration Research2013,8,12:11
3Image 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 2013Journal of Traditional Chinese Medicine2013,33,2:7
4Neuronal 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 2011Neural Regeneration Research2011,6,15:6
5Niacin alters the ruminal microbial composition of cattle under high-concentrate condition显示文摘To understand the effects of niacin on the ruminal microbial ecology of cattle under high-concentrate diet condition, Illumina MiSeq sequencing technology was used. Three cattle with rumen cannula were used in a 3 x 3 Latin-square design trial. Three diets were fed to these cattle during 3 periods for 3 days, respectively: high-forage diet(HF; forage-to-concentrate ratio = 80:20), high-concentrate diet(HC;forage-to-concentrate ratio=20:80), and HC supplemented with 800 mg/kg niacin(HCN). Ruminal pH was measured before feeding and every 2 h after initiating feeding. Ruminal fluid was sampled at the end of each period for microbial DNA extraction. Overall, our findings revealed that subacute ruminal acidosis(SARA) was induced and the a-diversity of ruminal bacterial community decreased in the cattle of HC group. Adding niacin in HC could relieve the symptoms of SARA in the cattle but the ruminal pH value and the Shannon index of ruminal bacterial community of HCN group were still lower than those of HF group. Whatever the diet was, the ruminal bacterial community of cattle was dominated by Bacteroidetes,Firmicutes and Proteobacteria. High-concentrate diet significantly increased the abundance of Prevotella,and decreased the abundance of Paraprevotella, Sporobacter, Ruminococcus and Treponema than HF.Compared with HC, HCN had a trend to decrease the percentage of Prevotella, and to increase the abundance of Succiniclasticum, Acetivibrio and Treponema. Increasing concentrate ratio could decrease ruminal pH value, and change the ruminal microbial composition. Adding niacin in HC could increase the ruminal pH value, alter the ruminal microbial composition.Dan Luo Yufei Gao Youyou Lu Mingren Qu Xiaowen Xiong Lanjiao Xu Xianghui Zhao Ke Pan Kehui Ouyang 2017Animal Nutrition2017,,2:4
6Determination of 4-tert-octylphenol in surface water samples of Jinan in China by solid phase extraction coupled with GC-MS显示文摘Octylphenols, considered as xenoestrogens, mainly exist as 4-tert-octylphenol (OP) in aquatic environments. The high stability and accumulation of OP in aquatic systems have caused endocrine disruption. The OP in surface water in Jinan, China was analyzed by gas chromatography-mass spectrometry (GC-MS) coupled with solid phase extraction (SPE). Water samples were extracted by SPE on a cartridge system containing C-18 as sorbent. To increase sensitivity and selectivity, OP was derivatized to 4-tert-octyl-phenoxy silane. With the use of phenanthrene-d10 as internal standard, the detection limit based on signal-to-noise ratio (S/N = 3) was 0.06 ng/mL. The average recovery was from 84.67% to 109.7%. The precision of the method given as the relative standard deviations (RSD) was within the range 6.24%-12.96%. In the target water samples, the concentrations of OP were as follows: 15.88-71.24 ng/L for Jinxiuchuan Reservoir, 3.850-26.68 ng/L for the city moat, 6.930-41.56 ng/L for Daming Lake, 66.03-474.2 ng/L for Xiaoqing River, 14.66-17.72 ng/L for the Yellow River, and 10.60-26.43 ng/L for Queshan Reservoir. The Xiaoqing River was seriously polluted due to the discharge of wastewater from Jinan. Jinxiuchuan Reservoir had a higher concentration of OP compared with the Yellow River and Queshan Reservoir, which is ascribed to the surrounding human activities. These data are reported for the first time, providing strong support for the control of OP pollution in Jinan.Xueyu Yang Mingren Liu Zhongpeng Wang Qian Li Zhaoliang Zhang 2013Journal of Environmental Sciences2013,25,8:4

19Influence of Bias on the Properties of Carbon Nitride Films Prepared by Vacuum Cathodic Arc Method显示文摘Carbon nitride films have been synthesized in a wide range of biases from 0 to -900 V by vacuum cathodic arc method. The N content was about 12.0~22.0 at. Pct. Upon increasing the biases from 0 to -100 V, the N content increased from 15.0 to 22.0 at. Pct which could be attributed to the knot-on effect. While the further increasing biases led to the gradual falling of the N content to 12.0 at. Pct at -900 V due to the enhancement of the sputtering effect. Below -200 V, with the increasing biases the sp2C fraction in the films decreased, as a result of which the I(D)/I(G) fell in the Raman spectra and the sp peaks also showed the decreasing tendency relative to the s peaks in the VBXPS (valence band X-ray photoelectron spectroscopy). While above -200 V, the sp2C fraction increased and the films became graphitinized gradually, accompanying which theI(D)/I(G) rose from -200 V to -300 V and the Raman spectra even showed the graphite characteristic above -300 V and the sp peaks rose again relative to the s peak. The carbon nitride films mainly consist of three types of bonding: CC, sp2CN and sp3CN bonds. In the first stage the sp3CN relative ratio rises and falls in the second stage, which corresponded well with the variation of the sp2C in the films. The subplantation mechanism resulting from the effect of ion energy played an important role in decidingthe variation of the microstructure of the carbon nitride films.Zhimin ZHOU, Lifang XIA and Mingren SUNSchool of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, China 2004Journal of Materials Science & Technology2004,20,6:0
20Calculation of the Gas Injection Rate and Pipe String Erosion in Nitrogen Drilling Systems显示文摘Detailed information is provided for the design and construction of nitrogen drilling in a coal seam.Two prototype wells are considered.The Guo model is used to calculate the required minimum gas injection rate,while the Finnie,Sommerfeld,and Tulsa models are exploited to estimate the ensuing erosion occurring in pipe strings.The calculated minimum gas injection rates are 67.4 m^(3)/min(with water)and 49.4 m^(3)/min(without water),and the actual field of use is 90–120 m^(3)/min.The difference between the calculated injection pressure and the field value is 6.5%–15.2%(formation with water)and 0.65%–7.32%(formation without water).The results show that the Guo model can more precisely represent the situation of the no water formation in the nitrogen drilling of a coal seam.The Finnie,Sommerfeld,and Tulsa models have different sensitivities to cutting densities,particle size,impact velocity and angle,and pipe string hardness.Mingren Shao Chunpeng Wang Degui Wang Wenbo Mei Mingjie Li Hao Yang 2022Fluid Dynamics & Materials Processing2022,18,2:0
