Two Sets of Acupoint Combination of Similar Functions engage Shared Neural Representation:A Functional Magnetic Resonance Imaging Study

引用

Chinese Journal of Integrative Medicine 2014年第3期20卷 184-193页

作者：赵凌秦伟刘继欣方莉董明皓张富文蒋萃孙金铂 karen.M.von Deneen 梁繁荣 College of Acupuncture and Tuina Chengdu University of Traditional Chinese Medicine Life Sciences Research Center School of Life Sciences and TechnologyXidian University The Third Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine The Teaching Hospital of Chengdu University of Traditional Chinese Medicine

Objective： To investigate whether the neural representations underlying alternating two acupoint combinations （ACs） are the same or not. Methods： In this functional magnetic resonance imaging study, two sets of analgesia ACs were utilized, including Waiguan （Te5） and Qiuxu （GB40） for Group A, and Neiguan （PC6） and Taichong （LR3） for Group B, which are the most commonly adopted in clinical treatment. each group had 20 healthy subjects. An experinlental design was proposed, which consisted of a pre-needling resting phase, a needling phase and a post-needling resting phase. This paradigm optimally mimics the clinical protocol as well as focuses on both the stimulation and the resting periods. The results were subjected to general linear model analysis, conjunction analysis and the functional connectivity analysis. Results： The rostral anterior cingulated cortex was engaged in the initiative period of the acupuncture effect in both groups, and it was chosen as the seed region for the functional connectivity analysis for the following resting period. The results showed that several shared brain regions were involved in both groups, in particular the insula, amygdala and hypothalamus. Moreover, significant differences were located at the posterior cingulated cortex as revealed by a two sample t-test （P〈0.05, corrected）. Other regions showed no significant differences. This finding was further supported by the spatial correlation analysis that the two groups were significantly correlated （r=0.51, P〈0.01）. Conclusion： This preliminary research helps us understand the neurophysiological mechanisms of acupuncture when following clinical guidelines on ACs, as well as provides an important opportunity to develop better treatment strategies for reducing, or even preventing pain.

AIM： To investigate whether the stimulation of peripheral blood mononuclear cells （PBMNC） with the cell debris and cell extraction of different probiotic strains is similar or species specific. MeTHODS： Three strains of bifidobacteria, 4 strains of lactobacilli, and e. coli nissle were sonicated and centrifuged in order to divide them into cell extract and cell debris. PBMNC were separated by density gradient and incubated for 36 h with either the cell debris or the cell extract of single strains of probiotic bacteria in doses from 10^2 to 10^8 CFU/mL. Cell supernatants were taken and interleukin （IL）-10, IL-1β, and tumor necosis factor （TNF）-α were determined by eLISA. ReSULTS： Depending on the species super-family, the strains had different stimulation patterns. except for both L. casei strains, the cell extract of bitTdobacteria and/actobacilli had less stimulating capacity than cell debris, whereas the cell extract of e. coli nissle had similar stimulating properties to that of the cell debris of the strain and significantly more stimulating capacity than that of bifidobacteria and lactobacilli. The cell debris of bifidobacteria stimulated more cytokine release than the cell debris of lactobacilli. The cell debris of lactobacilli did not have a stimulating capacity when lower concentrations were used. Neither cell extraction nor cell debris had an inhibitory effect on the production of the tested cytokines by stimulated PBMNC. CONCLUSION： The incubation of probiotic strains, which have been used in clinical trials for inflammatory diseases, with immunocompetent cells leads to different species specific reactions. High IL-10 response to cell debris of bifidobacteria and e. coli nissle can be found. This corresponds to positive effects of bihdobacteria and e. coli nissle in clinical trials for inflammatory bowel disease compared to negative outcomes obtained with lactobacilli.

Response of Hypercholesterolemic Rats to Sesamum indicum Linn Seed Oil Supplemented Diet

引用

Journal of Life Sciences 2012年第11期6卷 1214-1219页

作者： Olubunmi Bolanle Ajayi James Braimoh karen Olasunkanmi Department of Biochemistry Faculty of Sciences Ekiti State University P.M.B. 5363 Ado-Ekiti Nigeria

Fatty acid composition of Sesamum indicum oil was determined by gas chromatography and the response of hypercholesterolemic rats to diet supplemented with Sesamum indicum seed oil was investigated. Twenty four rats weighing between 120-130 g were randomly assigned into four groups. Group A was fed normal diet, Group B, C and D were fed hypercholesterolemic diet （i.e. 20% fat ＋ 1% cholesterol） for two weeks to establish hypercholesterolemia. Group B were maintained on hyper diet while C and D were fed 5% and 10% benniseed oil supplemented diet for four weeks. Plasma was collected and analyzed for TC （total cholesterol）, HDL-C （high density lipoprotein）, LDL-C （low density lipoprotein） and TG （triglycerides） levels. Linoleic acid （42.44%） and oleic acid （40.60%） were the major unsaturated fatty acid in the oil. Significant increase （P 〈 0.05） was observed in the TC, TG, LDL and LDL/HDL ratio of the hypercholesterolemic rats compared to the normal control. Supplementation with Sesamum indicum seed oil at 5% and 10% levels resulted in significant decrease （P 〈 0.05） in TC, TG, LDL and LDL/HDL ratio, and significant increase in the HDL-C. The high level of unsaturated fatty acid in the oil may in part be responsible for the hypocholesterolemic effect of the oil.

AIM: To test antibiotic-loaded coating for efficacy in reducing bacterial biofilm and development of osteomyelitis in an orthopaedic model of implant infection. MeTHODS: Phosphatidylcholine coatings loaded with 25% vancomycin were applied to washed and sterilized titanium wires 20 mm in length. A 10 mm segment was removed from rabbit radius(total = 9; 5 coated, 4 uncoated), and the segment was injected with 1 × 106 colony forming units(CFUs) of Staphylococcus aureus(UAMS-1 strain). Titanium wires were inserted throughthe intramedullary canal of the removed segment and into the proximal radial segment and the segment was placed back into the defect. After 7 d, limbs were removed, X-rayed, swabbed for tissue contamination. Wires were removed and processed to determine attached CFUs. Tissue was swabbed and streaked on agar plates to determine bacteriological ***: Antibiotic-loaded coatings resulted in significantly reduced biofilm formation(4.7 fold reduction in CFUs; P es and reduced bacteriological score in surrounding tissue(4.0 ± 0 for uncoated, 1.25 ± 0.5 for coated; P = 0.01). Swelling and pus formation was evident in uncoated controls at the 7 d time point both visually and radiographically, but not in antibiotic-loaded ***: Active antibiotic was released from coated implants and significantly reduced signs of osteomyelitic symptoms. Implant coatings were well tolerated in bone. Further studies with additional control groups and longer time periods are warranted. Antibiotic-loaded phosphatidylcholine coatings applied at the point of care could prevent implant-associated infection in orthopaedic defects.

In the past few years there has been a growth in the use of nanoparticles for stabilizing lipid membranes that contain embedded proteins. These bionanoparticles provide a solution to the challenging problem of membrane protein isolation by maintaining a lipid bilayer essential to protein integrity and activity. We have previously described the use of an amphipathic polymer （poly（styrene-co-maleic add）, SMA） to produce discoidal nanoparticles with a lipid bilayer core containing the embedded protein. However the structure of the nanoparticle itself has not yet been determined. This leaves a major gap in understanding how the SMA stabilizes the encapsulated bilayer and how the bilayer relates physically and structurally to an unencapsulated lipid bilayer. In this paper we address this issue by describing the structure of the SMA lipid particle （SMALP） using data from small angle neutron scattering （SANS）, electron microscopy （eM）, attenuated total reflection Fourier transform infrared spectroscopy （ATR-FTIR）, differential scanning calorimetry （DSC） and nuclear magnetic resonance spectroscopy （NMR）. We show that the particle is disc shaped containing a polymer ＂bracelet＂ encircling the lipid bilayer. The structure and orientation of the individual components within the bilayer and polymer are determined showing that styrene moieties within SMA intercalate between the lipid acyl chains. The dimensions of the encapsulated bilayer are also determined and match those measured for a natural membrane. Taken together, the description of the structure of the SMALP forms the foundation for future development and applications of SMALPs in membrane protein production and analysis.
