Objective To investigate the effect of edaravone plus beating-heart-preservation as well as beating-heart-transplantation technique on myocardial protection in donation after cardiac death (DCD) heart transplantation.Methods Twenty-four swine (body weight 28 ± 3 kg) were divided into two groups (n =12 each),and another twelve swine were used for blood donor.( 1 ) Experimental group:cardiac arrest was induced by asphyxiation (turning off the ventilation),and then the swine were subjected to 25-min warm ischemia,and cold oxygenated blood was perfused before the harvest of donor heart.Cardiac resuscitation was initiated by the ex vivo perfusion equipment and warm oxygenated blood was reperfused.Edaravone was given before harvesting of donor heart and in the early period of reperfusion.Donor hearts were kept beating throughout preservation and transplantation period.(2) Control group:all animals were treated in the same way except for without the application of edaravone.Hemodynamic,myocardial enzymes,and water content of myocardium were observed,and uhrastructural damage of cardiomyocytes was examined.Results All recipient animals could wean from cardiopulmonary bypass successfully.Left ventricular compliance and left ventricular contractility were significantly better preserved in experiment group than in control group.Though there was no significant difference in myocardial creatase level,the myocardial edema in experimental group was milder than in control group,and myocardial ultrastructure was better preserved in experimental group.Conclusion Heart from DCD,even though experienced 25-min warm ischemia after cardiac arrest by asphyxiation,still could be resuscitated via isolated heart perfusion equipment ( i.e.,beating-heart-preservation ) successfully.Furthermore,beating-hearttransplantation is feasible technically.Edaravone,a free-radical scavenger,could alleviate asphyxiation-induced myocardial injury,and further improve post-transplantation heart function.

Objective To evaluate the effects of fasudil on DCD hearts .Methods Sixteen domestic ,mixed‐breed male porcine [mean body weight (28 ± 3)kg] were randomly divide into experiment group and control group (n= 8 in each) .Experiment group :animals were sedated ,anesthetized and paralyzed .Mechanical ventilation with room air was provided .After thoroctomy ,cardiac arrest was established by bloodletting ,and then keeps at room temperature for additional 25 minutes (warm ischemia) .Hearts were perfused via the aortic root with fasudil (0 .1 mg/kg) enriched cold Stanford solution for coronary artery flushing ,rapidly excised and the aorta was cannulated .Hearts were subjected to isolated Langendorff perfusion (retrograde perfused with warm oxygenated autologous blood) afterwards ,and then underwent 20 minutes of equilibrium ,immersed in fasudil (0 .5 mg/kg) enriched cold Stan‐ford solution for 2 hours in situ cold preservation .Finally ,all the hearts were resuscitated with the warm oxygenated autologous blood perfusion .Control group :hearts from the animals experienced the same except for fasudil supplement .Left ventricular per‐formances were evaluated .Coronary blood flow ,myocardial infarction volume ,myocardial water content ,and myocardial enzyme were measured .Myocardial electron microscopic examinations were carried out as well .Results All the hearts from both groups were successfully resuscitated ,fasudil significantly decreased water content ,enzyme leakage (P< 0 .01 each versus control group) , and increased coronary blood flow (P< 0 .01 versus control group) .Left ventricular function were better preserved (P< 0 .01 each versus control group) .All hearts lacked severe necrosis as determined by tetrazolium staining ,myocardial infarction volume were decresed in experiment group (P< 0 .01 each versus control group) .Intracellular components retained various types of organelle in both group ,but still ultrastructural alterations in control group were more distinctive than in experiment group .Conclusion (1) Donor heart arrested by exsanguinations and plus 25 minutes warm ischemia ,could still be resuscitated with satisfactory result ;(2) The addition of fasudil to Stanford solution (before excise of graft ,during the cold preservation) ,might alleviate DCD heart I‐R in‐jury ,improving the effect of DCD heart preservation ,and hopefully ,might be a novel arsenal in clinical DCD heart transplantation in the future .

Objective To evaluate and verify the preventive and therapeutic effects of electroacupuncture (EA) plus pelvic floor muscle training (PFMT) in treating mild-moderate female stress urinary incontinence (SUI). Method By adopting a single-blind randomized controlled design, eighty-two SUI patients were randomized into an observation group of 40 cases and a control group of 42 cases. The observation group was intervened by EA plus PFMT, while the control group only received PFMT. Before the treatment and after 4-week treatment, the 1 h urine leakage amount, Incontinence Questionnaire Short Form (ICI-Q-SF) and improvement rate were evaluated in the two groups, to analyze the effects of the two methods in improving mild-moderate SUI. Result For mild SUI patients, the 1 h urine leakage amount and ICI-Q-SF score dropped significantly after the treatment in the observation group (P<0.05), and the observation group was significantly lower than the control group (P<0.05). For moderate SUI patients, the 1 h urine leakage amount and ICI-QSF score dropped significantly in both groups after the intervention (P<0.05), the observation group was significantly lower than the control group (P<0.05), and the improvement rate in the observation group was markedly higher than that in the control group (P<0.01). Conclusion EA plus PFMT caneffectively improve the urine leakage and urination in mild-moderate SUI patients. EA plus PFMT can effectively prevent the aggravation of moderate female SUI, and its effect is better than PFMT alone.
