Combination of the He and Mu acupoints is commonly used and has a synergistic effect on functional dyspepsia; however, its underlying mechanisms remain unclear. Therefore, a randomized controlled parallel clinical trial is currently underway at Chengdu University of Traditional Chinese Medicine, China. This trial is designed to explore the efficacy of and central responses to the He-Mu point combination in patients with functional dyspepsia using functional magnetic resonance imaging. A total of 105 patients with functional dyspepsia will be allocated into 3 groups: the low-He point group(puncturing at Zusanli(ST36)), Mu point group(puncturing at Zhongwan(CV12)), and He-Mu point combination group(puncturing at ST36 and CV12). Every participant will receive 20 sessions of manual acupuncture for 4 weeks. The needles will be inserted perpendicularly to a depth of 1 to 2 cun. The angle of rotation and twisting will range from 90 to 180 degrees, while lifting and thrusting will range from 0.3 to 0.5 cm. The various manipulations will be performed 60 to 90 times per minute. The needles will remain in place for 30 minutes, during which manipulation will be applied every 10 minutes. Magnetic resonance imaging will be performed before and after 20 sessions of acupuncture. The primary outcome is symptom improvement according to the Chinese version of the Nepean Dyspepsia Index. Secondary outcomes include the Leeds dyspepsia questionnaire, Self-Rating Anxiety Scale, Self-Rating Depression Scale, Beck Anxiety Inventory, Beck Depression Inventory, and visual analogue scale scores before and after 10 and 20 sessions of acupuncture. Needle sensation and adverse events will be used to assess the therapeutic effects. This study will promote more widespread awareness of the benefits of acupoint combination in the clinical setting and provide a further explanation of the neuromechanism by which acupuncture at the He-Mu point combination for functional dyspepsia.

At present, the majority of functional magnetic resonance imaging studies focus on the motor dysfunc- tion and the acute stage of ischemic stroke. This study recruited 15 right-handed ischemic stroke patients at subacute stage (15 days to 11.5 weeks) and 15 age-matched healthy participants. A rest- ing-state functional magnetic resonance imaging scan was performed on each subject to detect cerebral activity. Regional homogeneity analysis was used to investigate the difference in cerebral activities between ischemic stroke patients and healthy participants. The results showed that the ischemic stroke patients had lower regional homogeneity in anterior cingulate and left cerebrum and higher regional homogeneity in cerebellum, left precuneus and left frontal lobe, compared with healthy participants. The experimental findings demonstrate that the areas in which regional homogeneity was different between ischemic stroke patients and healthy participants are in the cerebellum, left precuneus, left triangle inferior frontal gyrus, left inferior temporal gyrus and anterior cingulate. These locations, related to the motor, sensory and emotion areas, are likely po- tential targets for the neural regeneration of subacute ischemic stroke patients.展开更多

In the current study, we examined structural changes in these brain regions by taking structural magnetic resonance imaging scans of 11 ischemic stroke patients and 15 healthy participants, and analyzing the data using voxel-based morphometry. Compared with healthy participants, patients exhibited higher gray matter density in the left inferior occipital gyrus and right anterior white matter tract. In contrast, gray matter density in the right cerebellum, left precentral gyrus, right middle frontal gyrus, and left middle temporal gyrus was less in ischemic stroke patients. The changes of gray matter density in the middle frontal gyrus were negatively associated with the clin- ical rating scales of the Fugl-Meyer Motor Assessment (r = -0.609, P = 0.047) and the left middle temporal gyrus was negatively correlated with the clinical rating scales of the nervous functional deficiency scale (r = -0.737, P = 0.010). Our findings call objectively identify the functional abnormality in some brain regions of ischemic stroke patients.展开更多

However, the central anal- gesic mechanism remains poorly understood. Studies have demonstrated that single stimulus of the verum acupuncture in healthy subjects can induce significant connectivity or activity changes in pain- related central networks compared with sham acupuncture. However, these findings are not indicative of the central analgesic mechanism of acupuncture at Shaoyang acupoints. Thus, we recruited 100 migraine sufferers and randomly assigned them into five groups: Shaoyang uncommon acupoint, Shaoyang common acupoint, Yangming uncommon acupoint, non-acupoint control, and blank control groups. Subjects were subjected to evaluation of curative effects and functional MRI prior to and after 10 and 20 acupuncture treatments. All subjects were diagnosed by physicians and enrolled following clinical physical examination. Subjects were observed during 1-4 weeks after inclusion. At the fifth week, the first clinical evaluation and resting functional MRI were conducted. The Shaoyang uncom- mon acupoint, Shaoyang common acupoint, Yangming uncommon acupoint, and non-acupoint control grousp then were treated with acupuncture, five times per week, 20 times in total over 4 weeks. The second and third clinical evaluations and resting functional MRI screenings were conducted following 10 and 20 acupuncture treatments. The blank control group was observed during the 5 to 8 week pe- riod, followed by clinical evaluation and resting functional MRI. The aim of this study was to examine changes in brain functional activity and central networks in subjects with migraine undergoing acu- puncture at Shaoyang uncommon acupoints. This study provides a further explanation of the central analgesic mechanism by which acupuncture at Shaoyang acupoints treats migraine,展开更多

The model abstracts chemical structures into mathematic graphs. The manipulation of the graphs enumerates the reactions among the large number of molecules, radicals, and other intermediates in the advanced oxidation processes. Using Canonical Simplified Molecular Input Line Entry Specification (Canonical SMILE) representation, the algorithm was able to simulate the reaction of contaminants containing both chain and ring structures. The input chemicals, reaction pattern, and the reaction rules could be specified by users through a graphical user interface. The degradation pathway of Atrazine was used as an example to demonstrate the capability of the algorithm. The generated reaction pathways were compared with those reported in literatures.展开更多

摘要Acupuncture is widely used to treat functional dyspepsia with satisfactory outcomes. Combination of the He and Mu acupoints is commonly used and has a synergistic effect on functional dyspepsia; however, its underlying mechanisms remain unclear. Therefore, a randomized controlled parallel clinical trial is currently underway at Chengdu University of Traditional Chinese Medicine, China. This trial is designed to explore the efficacy of and central responses to the He-Mu point combination in patients with functional dyspepsia using functional magnetic resonance imaging. A total of 105 patients with functional dyspepsia will be allocated into 3 groups: the low-He point group(puncturing at Zusanli(ST36)), Mu point group(puncturing at Zhongwan(CV12)), and He-Mu point combination group(puncturing at ST36 and CV12). Every participant will receive 20 sessions of manual acupuncture for 4 weeks. The needles will be inserted perpendicularly to a depth of 1 to 2 cun. The angle of rotation and twisting will range from 90 to 180 degrees, while lifting and thrusting will range from 0.3 to 0.5 cm. The various manipulations will be performed 60 to 90 times per minute. The needles will remain in place for 30 minutes, during which manipulation will be applied every 10 minutes. Magnetic resonance imaging will be performed before and after 20 sessions of acupuncture. The primary outcome is symptom improvement according to the Chinese version of the Nepean Dyspepsia Index. Secondary outcomes include the Leeds dyspepsia questionnaire, Self-Rating Anxiety Scale, Self-Rating Depression Scale, Beck Anxiety Inventory, Beck Depression Inventory, and visual analogue scale scores before and after 10 and 20 sessions of acupuncture. Needle sensation and adverse events will be used to assess the therapeutic effects. This study will promote more widespread awareness of the benefits of acupoint combination in the clinical setting and provide a further explanation of the neuromechanism by which acupuncture at the He-Mu point combination for functional dyspepsia.

摘要This study aimed to detect the difference in resting cerebral activities between ischemic stroke pa- tients and healthy participants, define the abnormal site, and provide new evidence for pathological mechanisms, clinical diagnosis, prognosis prediction and efficacy evaluation of ischemic stroke. At present, the majority of functional magnetic resonance imaging studies focus on the motor dysfunc- tion and the acute stage of ischemic stroke. This study recruited 15 right-handed ischemic stroke patients at subacute stage (15 days to 11.5 weeks) and 15 age-matched healthy participants. A rest- ing-state functional magnetic resonance imaging scan was performed on each subject to detect cerebral activity. Regional homogeneity analysis was used to investigate the difference in cerebral activities between ischemic stroke patients and healthy participants. The results showed that the ischemic stroke patients had lower regional homogeneity in anterior cingulate and left cerebrum and higher regional homogeneity in cerebellum, left precuneus and left frontal lobe, compared with healthy participants. The experimental findings demonstrate that the areas in which regional homogeneity was different between ischemic stroke patients and healthy participants are in the cerebellum, left precuneus, left triangle inferior frontal gyrus, left inferior temporal gyrus and anterior cingulate. These locations, related to the motor, sensory and emotion areas, are likely po- tential targets for the neural regeneration of subacute ischemic stroke patients.

摘要Our previous study used regional homogeneity analysis and found that activity in some brain areas of patients with ischemic stroke changed significantly. In the current study, we examined structural changes in these brain regions by taking structural magnetic resonance imaging scans of 11 ischemic stroke patients and 15 healthy participants, and analyzing the data using voxel-based morphometry. Compared with healthy participants, patients exhibited higher gray matter density in the left inferior occipital gyrus and right anterior white matter tract. In contrast, gray matter density in the right cerebellum, left precentral gyrus, right middle frontal gyrus, and left middle temporal gyrus was less in ischemic stroke patients. The changes of gray matter density in the middle frontal gyrus were negatively associated with the clin- ical rating scales of the Fugl-Meyer Motor Assessment (r = -0.609, P = 0.047) and the left middle temporal gyrus was negatively correlated with the clinical rating scales of the nervous functional deficiency scale (r = -0.737, P = 0.010). Our findings call objectively identify the functional abnormality in some brain regions of ischemic stroke patients.

摘要Pre-harvest sprouting(PHS)will have a serious effect both on the yield and quality of quinoa(Chenopodium quinoaWilld.).It is crucial to select and breed quinoa varieties with PHS resistance and excellent agronomic traits for guidance production and utilization of quinoa.A comprehensive evaluation of the PHS resistance and agronomic traits of 37 species of quinoa resources was conducted in Chengdu Plain.The evaluation used various methods,including grain germination rate(GR),grain germination index(GI),total spike germination rate(SR),total grain germination index(SI),grey correlation analysis(GCA),cluster analysis and correlation analysis.Results showed significant differences in PHS resistance and agronomic traits amongst the 37 quinoa resources.CDU-23 was most resistant to PHS within 24 h,with a germination rate of 2.67%and 0%according to the GR and SR results,respectively.However,in the same time,CDU-31 showed the maximum susceptibility to PHS based on the SR of 31.07%,while CDU-34 was the most sensitive to PHS according to the GR of 100%.The comprehensive evaluation identified one and nine kinds of high resistance species for grain and whole spike germination,respectively.In both cases,the coefficients of variation(CV)for these parameters were 34.78%and 82.13%,respectively.GCA results showed that the magnitude of the association between each trait and yield in the thirty-seven quinoa resources was in the following order:thousand grain weight>seed length>seed area>seed width.Although the seed weight of CDU-18 reached 3.7010 g,the seed weight of CDU-5 was only 1.6030 g.However,the size of the seeds,their width and area did not correlate with their 1000-grain weight.There was a complex correlation between PHS resistance index and agronomic traits.Based on clustering analysis,thirty-seven quinoa resources were classified into three taxa.It was found that various taxa differed in PHS resistance and agronomic traits.Several comparisons of the aggregated data led to the selection of five varieties of quinoa,of which CDU-2 presented excellent agronomic qualities and strong PHS resistance.This study has provided a reference for breeding excellent quinoa varieties with PHS resistance.

摘要Shaoyang acupoints are the most frequently used in migraine treatment. However, the central anal- gesic mechanism remains poorly understood. Studies have demonstrated that single stimulus of the verum acupuncture in healthy subjects can induce significant connectivity or activity changes in pain- related central networks compared with sham acupuncture. However, these findings are not indicative of the central analgesic mechanism of acupuncture at Shaoyang acupoints. Thus, we recruited 100 migraine sufferers and randomly assigned them into five groups: Shaoyang uncommon acupoint, Shaoyang common acupoint, Yangming uncommon acupoint, non-acupoint control, and blank control groups. Subjects were subjected to evaluation of curative effects and functional MRI prior to and after 10 and 20 acupuncture treatments. All subjects were diagnosed by physicians and enrolled following clinical physical examination. Subjects were observed during 1-4 weeks after inclusion. At the fifth week, the first clinical evaluation and resting functional MRI were conducted. The Shaoyang uncom- mon acupoint, Shaoyang common acupoint, Yangming uncommon acupoint, and non-acupoint control grousp then were treated with acupuncture, five times per week, 20 times in total over 4 weeks. The second and third clinical evaluations and resting functional MRI screenings were conducted following 10 and 20 acupuncture treatments. The blank control group was observed during the 5 to 8 week pe- riod, followed by clinical evaluation and resting functional MRI. The aim of this study was to examine changes in brain functional activity and central networks in subjects with migraine undergoing acu- puncture at Shaoyang uncommon acupoints. This study provides a further explanation of the central analgesic mechanism by which acupuncture at Shaoyang acupoints treats migraine,

摘要OBJECTIVE:To evaluate the efficacy and safety of acupuncture for optic atrophy.DATA SOURCES:A computer-based online search was conducted in Medline(1966-2008),Embase(1986-2008),the Cochrane Library(up to 2008),Chinese Biomedical Literature Database(1975-2008),China National Knowledge Infrastructure(1994-2008),VIP Database(1989-2008),Wanfang Database(1980-2008)and the National Research Register for ongoing trials.DATA SELECTION:Randomized,controlled trials addressing acupuncture treatment for patients with optic atrophy were included in this review.Inclusion criteria evaluated all forms of acupuncture therapy,such as filiform needle,electro-acupuncture,laser-acupuncture,acupressure,and auricular-acupuncture.Comparisons between acupuncture therapy and no treatment(blank)or placebo or Chinese medicine or Western medicine,as well as between acupuncture as an adjuvant and other treatments,were included.Exclusion criteria included studies comparing different forms of acupuncture therapy,different manipulations of acupuncture,and different acupuncture prescriptions,as well as non-randomized,controlled trials and animal studies.The domain-based evaluation criteria recommended by the guidelines in Chapter 8 of the Cochrane Handbook for Systematic Reviews of Interventions 5.0.1 was used to assess quality of the included studies.According to the type of outcome index,measurement data as assessed by weighted mean difference or standardized mean difference and 95%confidence interval;numeration data was estimated by relative risk and 95%confidence interval.Heterogeneity was analyzed by Meta-analysis using RevMan 5.0 software.MAIN OUTCOME MEASURES:Improved visual acuity and visual field was sought between treatment and control groups in the included articles.RESULTS:Seven randomized,controlled trials were included after screening and application of inclusion and exclusion criteria.However,the studies were of low methodological quality and lacked comparisons between acupuncture and no treatment or placebo.Applying visual acuity as the outcome index,meta-analysis indicated:the effect of medicine combined with acupuncture was superior to the medicine alone(relative risk=1.41,95%confidence interval 1.14-1.70,P〈0.01),the efficacy of acupuncture was better than medicine alone(relative risk=1.42,95%confidence interval 1.14-1.77,P〈0.01).Using visual field as the other outcome index,meta-analysis revealed:effectiveness of acupuncture or acupuncture in combination with medicine was superior to medicine alone(relative risk=1.47,95%confidence interval 1.27-1.69,P〈0.01).The 7 included articles were incorporated in a sensitivity analysis,and the overall effect showed a significant difference(relative risk=1.35,95%confidence interval 1.16-1.56,P〈0.01).Acupuncture was not associated with any adverse events in any of the studies.CONCLUSION:Acupuncture therapy was determined to be superior to medicine in terms of improved visual acuity and visual field.However,well-designed,randomized,controlled trials with adequate controls and scientific rigor are urgently needed.
摘要A model was developed to generate the complex degradation pathway of contaminants initiated by hydroxyl radical in the advanced oxidation processes. The model abstracts chemical structures into mathematic graphs. The manipulation of the graphs enumerates the reactions among the large number of molecules, radicals, and other intermediates in the advanced oxidation processes. Using Canonical Simplified Molecular Input Line Entry Specification (Canonical SMILE) representation, the algorithm was able to simulate the reaction of contaminants containing both chain and ring structures. The input chemicals, reaction pattern, and the reaction rules could be specified by users through a graphical user interface. The degradation pathway of Atrazine was used as an example to demonstrate the capability of the algorithm. The generated reaction pathways were compared with those reported in literatures.

摘要Highly dispersed Ni catalyst and alkaline promoters supported by mesoporous SiO2nanospheres were synthesized and applied as an active and stable catalyst for dry reforming of methane(DRM).The as-prepared Ni/MgO-mSiO2catalyst showed stable conversions of CH4 and CO2around 82%and 85%in 120 h of DRM reaction,which was superior in performance compared to similar catalysts in literatures.Based on the transmission electron microscope(TEM)images,energy-dispersive spectroscopy(EDS),CO-pulse adsorption,temperature programmed reduction of the oxidized catalysts by hydrogen(H2-TPR),X-ray photoelectron spectroscopy(XPS),temperature-programmed desorption of CO2(CO2-TPD),and thermal gravitational analysis(TGA),the promotion effect of MgO on the Ni catalyst was systematically studied.The introduction of Mg2+in synthesis enhanced the interaction between Ni2+and mSiO2,which led to a high dispersion of active centers and a strong“metal–support”interactions to inhibit the sintering and deactivation of Ni at reaction temperatures.On the other hand,Ni and MgO nanoparticles formed adjacently on mSiO2,where the“Ni-MgO”interface not only improved the Ni0 distribution and promoted the cracking of CH4but also promoted the activation of CO2and the elimination of carbon deposits.A high and stable conversion of CH4 and CO2were then achieved through the synergistic effect of Ni catalyst,MgO promoter,and mSiO2support.
