Aim To investigate the inhibition mechanisms of baclofen, a specific GABA B receptor agonist, on quantal glutamate release in the rat spinal dorsal horn neurons.Methods Whole-cell voltage-clamp technique was performed on dorsal horn neurons in rat spinal cord slice to record glutamatergic spontaneous miniature excitatory postsynaptic currents (mEPSCs). Baclofen action on quantal glutamate release was assessed by analyzing the change of mEPESC to baclofen perfusion.Results Baclofen(10 ?mol?L -1,50 s) depressed the frequency, but not amplitude distribution of glutamatergic mEPSCs, indicating baclofen presynaptic depression on glutamate release. The depression on frequency of mEPSCs persisted in Ca 2+-free solution, or in the presence of K + conductance blocker, 4-AP. On the other hand, the depression was occluded by forskolin, an activator of adenylate cyclase, but not protein kinase C (PKC) activator phorbol 12,13-dibutyrate (PDBu). N-ethylmaleimide (NEM), a sulphydryl alkylating agent, which destroys G protein, abolished baclofen depression.Conclusion Not presynaptic K +, Ca 2+ conductance or PKC, but G protein and/or cAMP pathway are involved in the baclofen depression on glutamate release in rat spinal dorsal horn;this depression might contribute to the analgesic action of baclofen at spinal level.

Objective:To make full use of existing variables set,study on the dynamic connection between economic growth,health input and investment benefits.Methods:Using Factor Augmented VAR(FAVAR) to draw common factors and perform VAR estimation with the variables sets.Results:The impact of economic growth on health output had two sides.Increasing health input would significantly stimulate health output and economic growth.The increase of health level would promote economic growth in short time and hamper in the long run.Conclusion:The government should increase health input and consider the health loss brought by economic growth.It should prevent the not rich but old risk with the pursuit of health benefit.

Objective To investigate the expression of glucose transporters(GLUTs)in placentas of pregnant women with abnormal glyeometabolism,and to explore its effect on glucose transport between mother and fetus and its relation with the birth weight.Methods Placentas of 41 pregnant women with abnormal glycometabolism(7 cases of DM,10 GDM A1,10 GIGT and 14 GDMA2)and 15 normal pregnant women as control were selected.The expression of GLUT1 and GLUT3was detected by immunohistochemistry.The birth weight was measured at delivery.Results GLUT1 was expressed in the syncytiotrophoblasts and cytotrophoblasts,whereas GLUT3 in some endothelial cells.The expressions of GLUT1 and GLUT3 were significantly different among the five groups(P＜0.01).Positive correlation was shown between the GLUT1 expression and the birth weight(rs=0.532,P＜0.01),but not in GLUT3 expression.Conclusions The expression of GLUT1 and GLUT3 in placentas of pregnancy with abnormal glycometabolism is enhanced,and GLUT1 may play a predominant role in the fetal glucose uptake.

Objective To establish a HPLC method for the determination of emodin in Niuhuang anti-inflammatory tablets. Method Thermo-Hypersil C18 (250 mm?4.6 mm, 5 ?m) was used, mobile phase was methanol-0.1% phosphoric acid (70∶30), with flow rate of 1.0 mL/min, detection wavelength of 254 nm, and column temperature was 40 ℃. Results There was a good linear relationship of emodin at the range of 0.020 11～0.402 2 ?g. Conclusion The method is simple, accurate, with better separation efficiency, wide linear range and high sensitivity. It can be used for quality control of the preparation.

Post-resuscitation multiple organ dysfunction syndrome(PR-MODS) is a major cause of low survival rate in patients with cardiac arrest.To fully understand the concept of PR-MODS is beneficial for estimating the state of illness,adjusting the therapy and eventually increasing the survival rate.This article reviews the development of PR-MODS concept and compares it with MODS of other causes,including their pathogeny,pathology,mechanism,diagnosis and therapy.

Objective To investigate the effect of Astragalus Membranaceus( Ast) and Angelica Sinensis( Ang) on antithrombosis and explore the molecular mechanism. Methods Plasminogen activator inhibitor-1 ( PAI-1) expression and activity were selected to observe the antithrombosis effect of Ast and Ang ( 3 and 6 mg/ml) on 0. 5 ng/ml TGF-?1 treated endothelial cells. PAI-1mRNA expression was detected by RT-PCR,PAI-1 antigen assay was detected by specific enzyme-linked immunosorbent assays( ELISA) ,and PAI-1 activity was measured by amidolytical assay. Results Ast and Ang significantly inhibited PAI-1 mRNA expreesion,antigen and activity in endothelial cells. The more powerful effects could be observed when treated by Ast and Ang together. Conclusion The PAI-1 mRNA expression,antigen and activity is inhibited effectively by Ast and Ang,which may be the mechanism of their treatment for antithrombosis.

The present study deals with the histochemistry of intramural plexus in stomach, duodenum, ileum, caecum, proximal colon, distal colon and rectum of normal adult guinea pig, including the reaction of Mg~(++)-ATPase, Ca~(++)-ATPase, CCO, SDH, G6PDH, carbohydrate, protein, nucleic acid and lipid in the enteric neurons. The reactions of all the enzymes mentioned above are observed under the light microscope and estimated semiquantitatively, among which, Mg~(++)-ATPase and Ca~(++)-ATPase are measured quantitatively with microphotometer (Leitz MPV II). Both results of light microscope, and microphotometer were analysed statistically. It was found that the above mentioned enzyme activities in the enteric neurons, suggesting that the neurons carry out active metabolism with these concerned enzymes. There were significant differences in some enzyme activities between myenteric plexus and submucous plexus, the former showed higher activity in SDH, while the latter in LDH, G6PDH, and two kinds of ATPase. It is suggested that there are some differences in. the major metabolic manner of carbohydrate, energy metabolism and functional activity between, two plexus. Besides, there were marked difference in enzyme activities among myenteric plexus of different part of digestive tract, the highest activity was showed in duodenum and proximal colon, the lowest was in caecum. These results indicate that enteric neurons differ greatly in functional state, but whether or not the variation of enzyme activities is related with the different types of neurons is unknown.

BACKGROUND:The molecule mechanism underlying endothelial progenitor cells(EPCs) differentiation into mature endothelial cells remains poorly understood.It requires for the regulation of the expression of various genes inside cells by various signal pathways,PI3K/Akt maybe included.OBJECTIVE:To investigate the role of PI3K/Akt in EPCs differentiation.DESIGN,TIME AND SETTING:A group control in vitro experiment was performed at the Pathology Laboratory in Shengjing Hospital of China Medical University from September 2007 to March 2008.MATERIALS:Wistar rats aged 4-6 weeks,of either gender.METHODS:EPCs were isolated from rat bone marrow with density gradient centrifugation.Then difference-speed adherence screening method was used to obtain the second time adherent cells,which then were inoculated in culture flask.After 5 days of culture,cells were collected to be indentified with laser confocal microscopy.The differentiating EPCs were those that have positive results of both AC133 and vWF stainings.MAIN OUTCOME MEASURES:The mRNA and the protein expression of AC133,vWF,PI3K and Akt in EPCs were detected with Western blot and reverse transcription-polymerase chain reaction(RT-PCR) after 0,3,7,10 and 14 days of inoculation respectively.RESULTS:According to the RT-PCR and Western blot detection,AC133 showed the strongest expression at day 0,the weaker at day 3 and none at day 7,10 and 14(P
