Objective To investigate the relation between omentin and coronary artery disease.Methods Eighty-eight eases were divided into 2 groups, coronary artery disease group (56 cases, includingacute coronary syndrome 28 cases and stable angina 28 cases), and non-coronary artery disease group (32cases). The plasma omentin levels were assayed by ELISA, and height, weight, blood pressure, totalcholesterol high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C),lriglyeeride (TG), high-sensitivity C-reactive protein were detected. Results The plasma omentin level incoronary artery disease group [(33.4 + 6.4) μg/L] was lower than that in non-coronary artery disease group [(51.8 + 7.7) μg/L](P= 0.034). Logistic analysis showed that the decline of omentin was an independent risk factor of coronary artery disease (P=0.012). Conclusions The decline of omentin is an independent risk factor of coronary artery disease. The plasma omentin may contribute, in part, to the pathogenesis of coronary artery disease.

BACKGROUND: PI3K is a family of enzymes involved in insulin signal transductlon pathway, the abnormal expression of which would affect synthesis, secretion, and migration of GLUT4, therefore, results In increased blood sugar, eventually, leads to diabetes.OBJECTIVE: To discuss the effects of insulin combined with selenium on PI3K and GLUT4 expression in cellular signal transduction of skeletal musde in diabetic rats.METHODS: Sprague Dawley (SD) rats were randomly divided into the control, diabetic, insulin-treated diabetic, selenium-treated diabetic and combination administration groups. All rats were prepared for diabetic models by injecting 50 mg/kg Streptozocin exception of the control group. Rats in the control and diabetic groups ware free to food and water; in the insulin treatment group,rats were subcutaneous injected 1 U/(kg·d) insulin. Rats in the selenium treatment group ware treated with a dose of 180 pg/kg per day of sodium selenite dissolved in redistilled water by gavage; and in the combination administration were given both treatments for 4 successive weeks. The levels PI3K end GLUT4 in skeletal muscle were estimated using Western blotting and immunohistochemistry techniques.RESULTS AND CONCLUSION: Immunohietochemistral results were accordance to Western blotting results, which showed the combination of insulin and selenium can remarkable Increase the levels of PI3K in skeletal muscle and GLUT4 in skeletal muscle membrane fraction, therefore, enhance the insulin signal transduction pathway.

Objective To investigate the relation between plasma omentin and glycometabolism.Methods Eighty-five cases were divided into 3 groups by glucose tolerance test:diabetes mellitus group (42cases), impaired glucose regulation group (17 cases) and normal glucose regulation group (26 cases). The level of plasma omentin was assayed by ELISA. Results The level of plasma omentin was (53.7 ± 7.7),(40.7 ±9.9) and (30.6 ±5.3) μg/L in diabetes mellitus group, impaired glucose regulation group and normal glucose regulation group. There was significant difference among three groups (P= 0.049) and there was significant difference between diabetes mellitus group and normal glucose regulation group (P= 0.014).The level of plasma omentin in normal glycometabolism was (53.7 ± 7.7) μ g/L , and the level of plasma omentin in abnormal glycometabolism was (33.5 ± 6.0) μ g/L. There was significant difference between them(P = 0.023 ). Logistic analysis showed that the decline of plasma omentin was the independent risk factor ofglycometabolic disturbance (P= 0.027). Conclusion Omentin may play important roles in glycometabolic disturbance.

Objective To evaluate the effect of remifentanil on heart rate variability,to discuss the optimal does of remifentanil for tracheal intubation.Methods Thirty six ASA Ⅰ～Ⅱ patients were randomly assigned to one of three groups(n=12/group)according to the remifentanil target plasma concentration(2、4、6ng/mL).No premedication was given.The target-controlled infusion(TCI)of renifentanil was initiated 5 minutes after the TCI of propofol given at the target plasma concentration of 3.5?g/mL.Mean arterial pressure(MAP),heart rate(HR),HF,LF,HF/LF were measured from baseline values to 5 minutes after the operation began every minutes.MAP,HR,HF,LF and HF/LF were obtained on the time point as follows:before the induction(T0),before the start of remifentanil TCI(T1),before laryngoscopy(T2),and maximum values after intubation(T3),before operation(T4),maximum values after operation.All the data obtained were analyzed used ANOVA with SPSS 11.5 statistical software.P

Objective:To investigate and compare the influences of Ghrelin and growth hormone releasing peptide 6(GHRP-6) on the contractility of stomach smooth muscle in guinea pigs,and to study the related mechanism.Methods: The myenteric plexuses of gastric fundus and antrium in guinea pigs were stimulated with electrical field stimulation(EFS) to observe the influence of Ghrelin and GHRP-6 on the contractility of stomach smooth muscle.The influences of N-nitro-L-arginine(L-NNA) and L-Arginine(L-AA) on the effect of Ghrelin and GHRP-6 were studied to disclose the mechanism of the effects of Ghrelin and GHRP-6.Results: The circular muscle tissues of the gastric fundus generated on-relaxations and off-contractions when stimulating myenteric plexuses with 1-16 Hz electrical field;the on-responses induced relaxation could be reduced by L-NNA and the off-contractions induced contraction could be blocked by atropine and guanethidine.In fundic strips,ghrelin and GHRP-6 could decrease the on-response induced relaxation and increase off-response induced contraction of the muscle,with the effect of Ghrelin obviously stronger than that of GHRP-6.L-NNA could increase the effects of Ghrelin and GHRP-6-induced muscle contraction,and L-AA could decrease their effects.In the antral strips,electrical field stimulation of myenteric plexuses led to disappearance of relaxation wave,only leaving off-contractions.Both ghrelin and GHRP-6 could increase that contraction.Conclusion: Both ghrelin and GHRP-6 can promote the contractility of stomach smooth muscle in guinea pigs through stimulating myenteric plexuses of gastric fundus and antrium,which might be related to the NO pathway.

Objective To research and develop an index system for training evaluation of national health emergency response.Methods A combinative approach was applied,including core expert group discussion,on-site investigation into parameters applied in Delphi assessment by field experts,national reviews by provincial health departments.Results Firstly,a framework of index system was constructed by core expert group based on literature;Secondly,the index was screened by mean score from field experts' investigation and suggestion of core experts,then an index system was formulated with 5 first level indexes,19 second level indexes and 46 third level indexes;Thirdly,index weight was determined according to the mean weight by field experts investigation and adjusted suggestion of core experts;Finally,the index system for training evaluation of national health emergency response was approved by Ministry of Health and applied to the whole nation.Conclusions The combinative approach is practical in research and developing index system.The index system covers a full range of related factors,and is applicable at provincial level.However,attention should be paid to improving training after evaluation.

Atomoxetine as a nonstimulant medicine was approved by the Chinese Food an Drug Administration and provide a new selection of treatment drugs for attention deficit hyperactivity disorder (ADHD). Tomoxetine is a noradrenaline transmitter reuptake inhibitor which can selectively inhibit synapsis noradrenaline transport protein, strengthen noradrenaline's resupination effect, and increase noradrenaline's activity released by synaptic cleft to improve the symptoms of the ADHD patients. Compared with methylphenidate, atomoxetine does not affect the concentration of the neurotransmitter dopamine and does not induce or increase the Tourettes' syndrome, therefore atomoxetine is more suitable to treat ADHD together with Tourettes syndrome. In this article the treatment of atomoxetine for ADHD, including the indications, dosage as well as adverse reactions and efficacy assessment are reviewed.
