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.

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.

The rapid development of human micro-ecology (human microbiome) in recent years has opened up new medical prospects for revealing the close relationship between microorganism and human health and disease.As the second genome of human,the special relationship between the microorganism and the host and its important function have brought new ethical and social problems,which requires to rethink and reform the existing ethical norms.This paper focused on the seven perspectives of “identity”,ownership,informed consent,risk benefit assessment,privacy,commercialization and public health,and demonstrated the importance to construct the ethics of micro-ecological research,which would enrich and expand the connotation of bioethics in theory and better guarantee the benign development of micro-ecology research in practice.

Objective To explore the diagnosis and treatment of hyperthyroidism in the pregnant women to improve maternal and infant healthy. Methods 47 cases of pregnant women with hyperthyroidism were divided into the treatment group receiving anti-thyroid drug PTU and the non-treatment group, and 30 cases of normal pregnant women served as control. The levels of serum T 3, T 4, TSH, FT 3 and FT 4 were measured before delivery, and the neonatal thyroid functions were evaluated by detecting the levels of T 3,T 4 and TSH of umbilical blood, as well as peripheral blood at 3th, 5th and 7th days after birth. Results The levels of T 3,T 4, TSH,FT 3 and FT 4 in the non-treatment group were significantly higher than those in the treatment group and control group(P

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.

The academic orientation determines the development direction of the subject, and also puts forward the corresponding requirements for the professional teaching. The deep development of anes-thesiology, perfect preoperative evaluation, refined management of clinical anesthesia and ultimately improv-ing the prognosis of patients are the total development directions of anesthesiology. Perioperative patient home (PSH) advocates taking patients as the center, dominated by anesthesia, based on evidence-based medicine in the perioperative period, solidarity and cooperation of multiple disciplines, the integration of a variety of medical resources, and providing continuous and efficient medical services for patients. PSH is required to ensure the safety of clinical anesthesia, reduce the incidence of anesthesia mortality and serious
complications, and improve the long-term survival rate and quality of life by improving the clinical work of the department of anesthesia. Practicing PSH, the anesthetic doctors should have the academic idea of the treatment of anesthesia. The concept requires making comprehensive use of a variety of teaching methods, putting emphasis on the training of basic knowledge, and in the teaching of basic knowledge, infiltrating the overall and local thinking and using lecture method in cooperation with the case teaching. To make solid promotion of PSH concept, we should use CBL teaching, strengthening the management of clinical anesthesia, and striving to promote the clinical practice of PSH.

AIM: To study the action of Fufang Danpu Decoction(FFDPD) on experimental gastric ulcer in mice. METHODS: The anti-gastric ulcer action of FFDPD was observed on the gastric ulcer induced by water immersion stress,absolute ethyl alcohol,reserpine and pyloric ligation.The effect on gastric secretion in rats was studied by pyloric ligation.The effect on gastrointestinal motility was observed by gastric emptying in mice. The analgesic effect was tested by the hot-plate test. RESULTS: FFDPD markedly inhibited gastric ulcer induced by water immersion stress,absolute ethyl alcohol,reserpine and pyloric ligation.FFDPD significantly inhibited the secretion of gastric acid and pipsin.FFDPD markedly delayed gastric emptying and enhanced hot pain threshold in mice. CONCLUSION: FFDPD may have anti-gastric ulcer effect,in relation to its inhibition of the secretion of gastric juice,of activity of gastric smooth muscle and analgetic effect.

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
