The theoretical foundation and scientific connotation of spirit-regulating and pain-relieving acupuncture method as well as its clinical application for pain are discussed. During spirit regulation, attention should be paid on regulating heart and brain, while acupoints should be selected mainly from the Heart Meridian, Pericardium Meridian and Governor Vessel. It has significant efficacy for refractory pain in clinical treatment. Spirit-regulating and pain-relieving acupuncture method is development of acupuncture treating spirit, and it is an important method for pain in clinic. Improvement on sensitization of pain center and brain function is considered as one of the mechanisms in spirit-regulating and pain-relieving acupuncture method.

The paper introduced the basic theory of outcome evaluation of media coverage,as well as hospital news and reports analysis methods and attitude measurement methods based on the frame theory and appraisal theory.In addition,the authors made a case study of hospital reports.Authors found that these methods can estimate public opinions,media hotspots and media cooperation based on statistics of news topics,information source,attitudes,reporting media and reprints,for reference of the hospital on its news report and communications.

OBJECTIVE: To observe the effect of electro-acupuncture of Neiguan (PC 6) on mean systemic arterial blood pressure and plasmic concentrations of NO and TNFalpha in endotoxin shock rats. METHODS: The model of endotoxin shock was induced by lipopolysaccharide (1.5 mg/kg i.v.) and D-galactosamine (100 mg/kg i.p.). Aminoguanidine (100 mg/kg i.p.) and electro-acupuncture of bilateral Neiguan (PC 6) were administered. A catheter was inserted into the right subclavian artery to record the change of blood pressure and the blood was abstracted out and centrifuged to determine the NO and TNFalpha concentrations. RESULTS: Electro-acupuncture of Neiguan (PC 6) retrieved the blood pressure and reduced the plasmic NO and TNFalpha concentrations. CONCLUSION: Electro-acupuncture of Neiguan (PC 6) expresses an anti-endotoxin shock effect by repressing the plasmic NO and TNFalpha concentrations smoothly and retrieving the blood pressure stably.

BACKGROUND: Apelin/APJ system has a wide range of physiological functions,but its intracellular signal transduction,in particular,apelin receptor desensitization,internalization,resensitization degradation,have still no consistent opinion.OBJECTIVE: To construct eukaryotic expression vector expressing human apelin receptor(APJ)tagged to red fluorescent protein(pDsRED-express-C1),and to determine the expression in human embryo kidney 293 cells.METHODS: The plasmid pcDNA3.1-hAPJ was used as a template for PCR amplification of human APJ.Following PCR amplification the PCR product were removed and enzymatic digestion with EcoR I and BamH I.Same enzymes were used to cut vector pDsRED-express-C1.The digestive product was ligated by conventional methods of connection,then transfected into Competent E.coli TOP10.Single clones were picked plasmid extraction,followed by restriction enzyme digestion and finally DNA sequencing.The recombinant plasmid with correct sequencing was transfected into human embryonic kidney cells,PI staining,followed by the observation under a confocal microscope.RESULTS AND CONCLUSION: PCR amplified a 1.2-kb fragment,which was consistent with the expected size of the human APJ.The pDsRed-hAPJ recombinant plasmid was cut into two fragments,one corresponded to the pDsRED-express-C1 vector size,and the other fragment corresponded to APJ target fragment.Confocal microscopy analysis showed that,APJ was expressed mainly in the membrane of human embryo kidney 293 cells.The pDeRed-hAPJ eukaryotic plasmid expression vector was successfully constructed and effective expression of this fusion protein is achieved,which might be instrumental in the study of displacement and intracellular localization of human APJ.

Aim To investigate the changes of phosphodiesterase4(PDE4,type 4 cAMP-specific PDE) activity,TNF-? and neutrophil recruitment in experimental rat lung injury(ALI).Methods ALI in the rat was induced by lipopolysacdharide(LPS).PDE4 activity was measured with HPLC,and the level of TNF-? was detected with ELISA,neutrophil infiltration in bronchoalveolar lavage fluid(BALF) and lung tissues was detected by cell count and morphological analysis.Result Lung tissue PDE4 activity significantly increased as early as 1 h,peaked 6 h,and then markedly lowered at 24 h after intratracheal administration of LPS,while there was a same time-course change of total white cell and neutrophil in the BALF(r=0.83,P

Objective: To explore the effect of Plastrum Testudinis on the three subtypes of NOS (nNOS,iNOS,eNOS) expression in rats with focal cerebral ischemia. Methods:Rat model of focal cerebral ischemia was set up by inserting nylon thread into the internal carotid artery . The expressions of nNOS, iNOS and eNOS was detected by immunohistochemical method to observe the effects of Plastrum Testudinis. Results: Expressions of nNOS and iNOS in cerebral cortex and caudate-putamen of Plastrum Testudinis treatment group were significantly lower than those of model control group (P

[Objective] To observe the effect of serum containing Carapax et Plastrum Testudinis (CPT) in inducing the differentiation of mesenchymal stem cells (MSC) of adult rats into neurons. [Methods] The fifth generation of MSC were induced by the serum containing CPT (sero-CPT) and the expressions of neurofilament (NF) protein and glial fibrillary acidic protein (GFAP), the marks of neuron-like cells were detected by immunohistochemical method. [Results] The expression of NF protein was positive after the stimulation of sero-CPT and the expression reached the peak 12 hours after induction. [Conclusion] Sero-CPT can induce the differentiation of MSC into neurons in vitro.
