AIM: To investigate the role of nitric oxide synthase (NOS), soluble guanylyl cyclase (sGC) and protein kinase C (PKC) signaling in tumor necrosis factor-? (TNF-?)-induced cardioprotection against hypoxia/reoxygenation (H/R) injury. METHODS: Neonatal rat ventricular myocytes were pretreated with TNF-? or sodium nitroprusside (SNP) or L-arginine (L-Arg), respectively, for 12 h and then subjected to continuous hypoxia for 12 h, followed by reoxygenation for 6 h. The manganese superoxide dismutase (Mn-SOD) activity of the cells was measured after H/R. Myocyte injury was determined by the release of lactic dehydrogenase (LDH). RESULTS: TNF-? (10~5 (U/L)) significantly increased the Mn-SOD activity and decreased release of LDH from ventricular myocytes. The cardioprotection against H/R injury was induced by the pretreatment with SNP (5 ?mol/L) or L-Arg (5 mmol/L), which was blocked by ODQ (10 ?mol/L), the specific sGC inhibitor, and Chel (5 ?mol/L), the specific PKC inhibitor. Pretreatment with L-NAME (100 ?mol/L), ODQ, Chel, antoxidant 2-MPG (400 ?mol/L) or tyrosine kinase inhibitor genistein (50 ?mol/L) attenuated the increased Mn-SOD activity and reduced LDH level induced by TNF-?. CONCLUSION: The results suggest that NO may play a role in TNF-?-induced cardioprotection, which is mediated by sGC and PKC. [

AIM: To explore the effects and mechanism of interleukin-2 (IL-2) on the positive effect of isoproterenol (ISO) in the isolated rat cardiomyocytes. METHODS: Enzymatically isolated cardiomyocytes were used. Peak twitch amplitude and maximal velocity of shortening/relaxation (?dL/dt_~max ) in the isolated cardiomyocytes were recorded with a microscope coupled to a charge-coupled device camera and [Ca~2+ ]i transients were determined with a fluorometric ratio method by using Fura-2/AM as Ca~2+ indicators. RESULTS: ① ISO increased the peak twitch amplitude and ?dL/dt_~max of the isolated cardiomyocytes. Perfusion for 15 min with IL-2 at 2?103 U/L, which had no effect at all, attenuated the enhancing effect of ISO on the peak twitch amplitude and ?dL/dt_~max . ② ISO increased the [Ca~2+ ]i transients of the single ventricular myocytes in a dose dependent manner and the corresponding EC_~50 values of ISO was (0.12?0.01) ?mol/L. Perfusion for 15 min with IL-2 at 2?103 U/L, which had no effect on the ~[Ca~2+ ]i transient at all, attenuated the enhancing effect of ISO and the corresponding EC_~50 was (0.44?0.06) ?mol/L. ③ The electrically induced [Ca~2+ ]i transient was significantly increased by pretreatment with 20 mg/L cholera toxin for ~12 h. The elevation of the [Ca~2+ ]i transient induced by cholera toxin was significantly attenuated by 2?103 U/L IL-2. ④ Forskolin (1 ?mol/L), the activator of adenyl cyclase, significantly increased the electrically induced [Ca~2+ ]i transient, which was attenuated by IL-2 at 2?103 U/L. CONCLUSION: IL-2 inhibits the positive effect of isoproterenol in the isolated single ventricular myocytes, in which Gs protein and adenyl cyclase are involved. [

Objective To observe the influence of early motor cardiac rehabilitation on the life quality of acute myocardial infarction patients. Methods 30 acute myocardial infarction patients underwent percutaneous transluminal coronary intervention (PCI) were randomly divided into rehabilitative group and control group which consist of 15 patients. The rehabilitative group received the individual sports programme and health education in addition to conventional treatment and nursing. The control group was just treated by traditional way. Barthel index was used to evaluate the self-care ability and life quality. Results The rehabilitative group had significantly higher self-care ability compared with control group after 30 days' treatment[(85.48 ±6.77)points vs (69.35 ±6.46)points] (P＜0.05).The rehabilitative group could care by themselves and carry on the light physical activity. In addition, heart rehabilitatione frequency was the favorable factor for improving the life quality of acute myocardial infarction patients.Conclusion Early motor cardiac rehabilitation could effectively improve the life quality of acute myocardial infarction patients which had a wide clinical application.

AIM: To investigate whether tumor necrosis factor ? (TNF?) pretreatment can inhibit mitochondrial permeability transition pore opening in isolated rat hearts subjected to hypoxia and reoxygenation. METHODS: Isolated perfused rat hearts were subjected to 30 min regional hypoxia (occlusion of left anterior descending artery) and 120 min reoxygenation. The infarct size, lactate dehydrogenase (LDH) release during reoxygenation and ventricular hemodynamic parameters were measured. RESULTS: Pretreatment with TNF? at concentration of 1?104 U/L for 7 min followed by 10 min washout reduced the infarct size and LDH release, and improved the left ventricular performance (left ventricular developed pressure and rate-pressure product) and left ventricular end-diastolic pressure during hypoxia and reoxygenation. Administration of atractyloside (Atr, an opener of mitochondrial permeability transition pore, 20 ?mol/L) for 20 min (last 5 min of hypoxia and first 15 min of reoxygenation) and paxilline (Pax, a calcium activated potassium channel antagonist, 1 ?mol/L) for 5 min before hypoxia attenuated the reduction of infarct size and LDH release and improved the left ventricular performance induced by TNF?. CONCLUSION: The findings indicate that in the isolated rat heart model, TNF? protects myocardium against hypoxia and reoxygenation injury via inhibiting mitochondrial permeability transition pore opening as well as activating calcium, activated potassium channel.

AIM: To investigate the role of mitochondrial calcium uniporter (MCU) in the cardioprotection by hypoxic preconditioning (HPC) and its relationship to mitochondrial permeability transition pore (MPTP). METHODS: Intraventricular balloon technique was employed to measure the left ventricular developed pressure (LVDP), the maximum rise/fall rate of left ventricular pressure (?dp/dt_ max ), and the left ventricular end-diastolic pressure (LVEDP) in Langendorff isolated rat heart. The hypoxia was achieved by ligation of left anterior coronary artery for 30 min followed by release of ligation for 120 min as reoxygenation. Hypoxic preconditioning was set as two episodes of 5 min global hypoxia and 5 min reoxygenation. RESULTS: Both HPC and treatment with ruthenium red (5 ?mol/L) during the first 10 min reoxygenation improved recovery of LVDP, ?dp/dt_ max and decreased LVEDP, which was associated with reduced infarct size and lactate dyhydrogenase release. These protective effects were attenuated by treatment with spermine (20 ?mol/L) during the first 10 min reoxygenation. Administration of cyclosporin A (0.2 ?mol/L) during the last 5 min of hypoxia period and first 15 min of reoxygenation period reduced the injury effect by spermine. CONCLUSION: These results indicate that inhibition of MCU is involved in the cardioprotection of HPC via inhibiting MPTP.

AIM: To investigate the effect of interleukin-2 (IL-2) on the intracellular calcium in electrically stimulated adult rat ventricular myocytes during anoxia and reoxygenation. METHODS: The isolated cardiac ventricular myocytes were exposed to 5 min anoxia followed by 10 min reoxygenation. Chemical anoxia was introduced by Krebs-Henseleit (K-H) solution containing 10 -3 mol/L sodium dithionite. The spectrofluorometric method was used to verify intracellular calcium transient with fura-2/AM as calcium fluorescence probe. RESULTS: It was shown that during anoxia, the amplitude of Ca 2+ transient was decreased, diastolic [Ca 2+ ] i, time to peak and time to relaxation of Ca 2+ transient were increased. All the parameters were got back but did not returned to the pre-anoxia level during reoxygenation. IL-2 at 2?10 5 U/L administrated during anoxia aggravated the effect of rexoxygenation on [Ca 2+ ] i transient. Pretreatment with a specific ? opioid antagonist, nor-BNI (10 -8 mol/L), abolished the effect induced by IL-2 during anoxia on the [Ca 2+ ] i transients, whereas specific ? opioid antagonist, naltrindole (10 -6 mol/L), did not cancel the effect. CONCLUSION: It is concluded that administration of IL-2 during anoxia aggravated the effect of reoxygenation on the [Ca 2+ ] i transients of isolated ventricular myocytes, which was mediated by cardiac ? opioid receptor pathway.

AIM: To investigate the effect of Dendranthema morifolium (Ramat) Tzvel (DM) on isolated rat heart and ventricular myocytes during ischemia/anoxia and reperfusion/reoxygenation.METHODS: The Langendorff perfused rat hearts were used to measure intraventricular pressure and coronary flow. The cell contraction and intracellular calcium transient in enzymatically isolated ventricular myocytes were determined. RESULTS: (1) DM (0.5 g/L) significantly attenuated the inhibitory effects induced by ischemia/reperfusion on left ventricular developed pressure (LVDP), ?dp/dt max, coronary flow and LVDP?HR, meanwhile increased the content of SOD and decreased the content of MDA in the myocardium; (2) DM (0.5 g/L) attenuated the inhibitory effects of anoxia and reoxygenation on [Ca 2+]i transient and cell contraction in isolated ventricular myocytes. CONCLUSION: DM attenuated the effects on contractility and intracellular calcium induced by ischemia/anoxia and reperfusion/reoxygenation in the isolated rat heart and the ventricular myocytes. The mechanism might be related to increase in SOD activity and maintaining [Ca 2+]i homeostasis.
