Objective To investigate the effects of orphanin FQ (OFQ) on simple and norepinephrineactivated cardiac function in isolated rat heart.Methods Male SD rats aged 3-4 months weighing 250-280 g were anesthetized with intraperitoneal 25% urethane 1.4-1.8 ml.Their hearts were excised and passively perfused with K-H solutionin a Lanngendorff apparatus.A fluid-filled latex balloon was inserted into left ventricle for measurement of developed pressure.Left ventricular systolic pressure(LVSP),left ventricular end-diastofic pressure(LVEDP),left ventricular developed pressure(LVDP=LVSP-LVEDP),HR and±dp/dtmax were measured.Sixty isolated rat hearts were randomly divided into 10 groups(n=6 each):Ⅰ control group (group C);Ⅱ,Ⅲ,Ⅳ OFQ1,OFQ2,OFQ3 group--OFQ 10-6,10-7,10-8 mol/L were administered via perfusion system respectively;Ⅴ OFQ+UFP group--OFQ 10-6 mol/L+UFP-101 (all OFQ antagonist) 10-6 mol/L were administered;Ⅵ NE group--norepinephrine 10-5 mol/L;Ⅶ,Ⅷ,Ⅸ NE+OFQ groups--NE 10-5 mol/L+OFQ 10-6,10-7,10-8 mol/L were administered respectively;Ⅹ NE+OFQ+UFP group--NE 10-5 mol/L+OFQ 10-6mol/L+UFP-101 10-6mol/L.Results LVSP,LVDP and±dp/dtmax were significantly increased while HR was significantly decreased in the 3 OFQ groups as compared with control group.LVSP,LVDP±dp/dt max and HR were significantly increased in the 3 NE+OFQ groups as compared with NE group.Conclusion OFQ has positive inotropic action and negative chronotropic effect on the isolated rat heart.OFQ Can enhance the positive inotropic and chronotropic effect of NE on the heart.

Objective To evaluate the effect of injecting UK and Herbesser into the target coronary artery where no-reflow happened during percutaneous coronary intervention. Methods Among the 820 acute coronary syndrome (ACS) patients who underwent PCI from Jan. 1990 to Apr. 2004, no-reflow phenomenon occurred in 86 patients. Three hundred cases with acute myocardial infraction (AMI) underwent primary PCI, no-reflow phenomenon occurred in 50 cases. In the other 520 unstable angina pectoris (UAP) cases, no-reflow phenomenon occurred in 36 cases during PCI. All the 86 patients with no-reflow were given intra-coronary arteries nitroglycerin but 78 of them showed no improvement in coronary perfusion and were in turns devided into 3 groups randomly. Group A (n=26) was given intra-vessel UK and Herbesser alternately. The maximan dosage of UK was 2?105 U kIU and 2 mg for Herbesser. Group B (n=24) was given intra-coronary Herbesser 500 ?g each time until the maximum amount reached 2 mg. Group C (n=28) was given UK which maximun dosage was 2?105 U. Results All the 26 cases in Group A showed significant improvement in blood flow (P

Wearing transfemoral prosthesis is the only way to complete daily physical activity for amputees. Motion pattern recognition is important for the control of prosthesis, especially in the recognizing swing phase and stance phase. In this paper, it is reported that surface electromyography (sEMG) signal is used in swing and stance phase recognition. sEMG signal of related muscles was sampled by Infiniti of a Canadian company. The sEMG signal was then filtered by weighted filtering window and analyzed by height permitted window. The starting time of stance phase and swing phase is determined through analyzing special muscles. The sEMG signal of rectus femoris was used in stance phase recognition and sEMG signal of tibialis anterior is used in swing phase recognition. In a certain tolerating range, the double windows theory, including weighted filtering window and height permitted window, can reach a high accuracy rate. Through experiments, the real walking consciousness of the people was reflected by sEMG signal of related muscles. Using related muscles to recognize swing and stance phase is reachable. The theory used in this paper is useful for analyzing sEMG signal and actual prosthesis control.

BACKGROUND:Current cardiac bioprostheses and mechanical valves are shown to have some flaws and shortcomings, and tissue-engineered heart valves which can avoid these problems are becoming an ideal choice for valve replacement.
OBJECTIVE:To explore the experimental progress in the construction of tissue-engineered heart valves.
METHODS:Experimental studies related to tissue-engineered heart valves were retrieved in databases. Three main elements for tissue-engineered heart valves are seed cells, scaffold materials, and cellseeding.
RESULTS AND CONCLUSION:Cardiac valve repair and replacement is the primarily surgical treatment for valvular heart disease. At present, seed cells mainly for construction of tissue-engineered heart valves include vascular endothelial cells, endothelial progenitor cells and bone marrow mesenchymal stem cells. The acellular scaffold has good biomechanical properties and histocompatibility. After cellseeding, a continuous celllayer wil form on the scaffold surface, which makes it possible to construct tissue-engineered heart valves. Tissue-engineered heart valve has a good prospect, but it is stil in the early stage of research and there are stil many problems that need to be solved.
