Abstract:

BACKGROUND: In recent years, delayed protection of drug pretreatment has become a hot spot in the field of pretreatment, and sufentanil is a non-selective opioid receptor agonist that plays a significant myocardial protective role.
OBJECTIVE: To investigate the protective effect of sufentanil combined with umbilical cord blood stem cell transplantation on injured myocardium after myocardial infarction.
METHODS: Myocardial infarction model by ligating the left anterior descending coronary artery (ischemia 30 minutes and reperfusion 180 minutes) was made in 90 healthy adult Wistar rats, and then these rat models were randomly divided into ischemia-reperfusion (IR) group, cell transplantation group, combined treatment group (n=30/group). Rats in the IR group were given intraperitoneally intravenous injection of
1 mL normal saline 5 minutes before IR; rats in the cell transplantation group were given intraperitoneally intravenous injection of 1 mL umbilical cord blood stem cell suspension 5 minutes prior to IR; and rats in the combined treatment group were given intraperitoneally intravenous injection of 10 μg/kg sufentanil 10 minutes before IR and 1 mL umbilical cord blood stem cell suspension 5 minutes prior to IR. Two weeks later, related indicators were detected.
RESULTS AND CONCLUSION: Compared with the IR group, myocardial infarct size was reduced significantly in the combined treatment group, followed by the cell transplantation group (P < 0.05). Lowest levels of serum creatine kinase, lactate dehydrogenase and troponin I were obtained in the combined treatment group followed by the cell transplantation group and IR group, while highest level of nitric oxide was observed in the combined treatment group followed by the cell transplantation group and IR group(P < 0.05). Highest expression of Caspase-3 protein was recorded in the combined treatment group, followed by the cell transplantation group and IR group (P < 0.05). Significantly increased left ventricular diastolic blood pressure and decreased left ventricular end diastolic pressure were found in the two cell transplantation groups compared with the IR group (P < 0.05). Moreover, pathological injury of the myocardial tissues was mitigated in the cell transplantation group and significantly relived in the combined treatment group compared with the IR group. In conclusion, the combined use of sufentanil and umbilical cord blood mesenchymal stem cell transplantation can reduce the degree of myocardial infarction and protect against myocardial injury.
