Cupping therapy of Chinese medicine is able to relieve a variety of diseases or clinical conditions, which results from the comprehensive effects of multiple types of stimulation exerted onto the regional acupoint areas. Among the stimuli, the negative pressure from cupping is one of the main factors inducing therapeutic effects. In the present paper, the authors review development of researches on the underlying mechanism of therapeutic effects of cupping-negative pressure from 1) the factor of intra-cup negative pressure; 2) influence of intra-cup negative pressure on cup-blackspot formation; 3) influence of cupping on regional blood vessels and blood flow; 4) effect of cupping on regional ultrastructure of the capillary in the raw-surface tissue; 5) effect of cupping-negative pressure on regional endothelial cells; and 6) biological effects of negative pressure drainage. Generally, cupping induced negative pressure can dilate local blood vessels to improve microcirculation, promote capillary endothelial cells repair, accelerate granulation and angiogenesis, etc., in the regional tissues, normalizing the patients' functional state at last.

Mycorrhiza | Year: 2014

Both arbuscular mycorrhizal (AM) fungi and root hairs play important roles in plant uptake of water and mineral nutrients. To reveal the relative importance of mycorrhiza and root hairs in plant water relations, a bald root barley (brb) mutant and its wild type (wt) were grown with or without inoculation of the AM fungus Rhizophagus intraradices under well-watered or drought conditions, and plant physiological traits relevant to drought stress resistance were recorded. The experimental results indicated that the AM fungus could almost compensate for the absence of root hairs under drought-stressed conditions. Moreover, phosphorus (P) concentration, leaf water potential, photosynthetic rate, transpiration rate, stomatal conductance, and water use efficiency were significantly increased by R. intraradices but not by root hairs, except for shoot P concentration and photosynthetic rate under the drought condition. Root hairs even significantly decreased root P concentration under drought stresses. These results confirm that AM fungi can enhance plant drought tolerance by improvement of P uptake and plant water relations, which subsequently promote plant photosynthetic performance and growth, while root hairs presumably contribute to the improvement of plant growth and photosynthetic capacity through an increase in shoot P concentration. © 2014, Springer-Verlag Berlin Heidelberg.

Use accurate springback evaluation method to guide modifying die surfaces, that is the first pledge to rectify the springback of sheet metal stamping by mould compensation method. Aiming at the problems in springback evaluation of complex sheet metal stamping and to improve the simulation precision of finite element, presented the face-to-face selection methods to select reference points evaluating springback, then used this method on the spiral blade's reference points selecting and springback evaluation. Result shows that this method can determine the range of reference points evaluating springback rapidly and get a comparatively accurate result of springback evaluation. © (2013) Trans Tech Publications, Switzerland.

To observe the effect of needle-implantation (NI) at "Neiguan" (PC 6) on the expression of myocardial transforming growth factor-beta 3 Protein(TGF-beta 3) and mRNA in Chinese miniswine with myocardial ischemia (MI) injury. A total of 32 Chinese Guizhou miniswine were randomly and equally divided into Sham-operation group, model group, NI-PC 6 group and NI-Geshu (BL17, NI-BL17) group. MI injury model was established by occlusion of the descending anterior branch of the left coronary artery. Two acupuncture needles (veterinary use) were separately and subcutaneously implanted into "Neiguan" (PC 6) and "Geshu" (BL17) areas for 7 days. TGF-beta 3 protein and mRNA expressions were determined by Western blot and real-time PCR techniques, separately. In comparison with the sham-operation (sham) group, TGF-beta 3 protein and mRNA expressions in model group were upregulated significantly (P < 0.05). While compared with the model group, myocardial TGF-beta3 mRNA expression was upregulated considerably in NI-PC 6 group (P < 0.01), rather than in NI-BL17 group (P > 0.05), and myocardial TGF-beta 3 expression in both NI-PC 6 and NI-BL17 groups was upregulated obviously (P < 0.01). Comparison between NI-PC 6 and NI-BL17 groups showed that the expression levels of myocardial TGF-beta 3 protein and mRNA were significantly higher in NI-PC 6 group than in NI-BL17 group (P < 0.05). Needle-implantation of "Neiguan" (PC 6) can upregulate myocardial TGF-beta 3 protein and mRNA expression in MI Chinese miniswine, which may contribute to its effect in improving the ischemic myocardial injury by way of enhancing the angiopoiesis.

Astilbin in 28 Smilax glabra (red and white cross-section) from different sources was determined by HPLC. Pharmacodynamics and component of S. glabra was investigated through inflammation experiment (penetration type). The analysis was performed on a Hypersil ODS2 column (4.6 mm x 250 mm, 5 microm) with the mobile phase of acetonitrile and 0. 1% acetic acid aqueous (21: 79) at a flow rate of 1.0 mL x min(-1). The detection wavelength was 291 nm, and the column temperature was 25 degrees C. Anti-inflammatory effect was compared from two type cross-section of Smilax glabra in capillary permeability experiment. Linear correlation was good in the range of 0.003 379-4.004 microg, and the average recoveries were 100.1%, 101.9%, 99.3%, respectively. The content of astilbin in white and red transverse section were 0.19%-2.46% and 2.10%-5.92%, respectively. Anti-inflammatory efficiency of sectioned red and white were were 21% and 32%, respectively. Astilbin content and anti-inflammatory effect is significantly different between red and white transverse section of S. glabra, the content of astilbin is not positively related with anti-inflammatory effect.
