RESUMEN
Effects of fast-track anesthesia (FTA) on miR-1 and neuropeptides in serum of patients undergoing cardiac surgery were investigated. A total of 147 patients who underwent cardiac surgery at Jining No. 1 people's Hospital from August 2015 to July 2018 were selected. There were 72 patients who received the FTA technology during cardiac surgery in the intervention group, and 75 patients who received routine anesthesia during cardiac surgery in the control group. Venous blood was, respectively, collected before anesthesia (T0), 30 min after artery opening (T1), 60 min after artery opening (T2), and 180 min after artery opening (T3). Expression of serum miR-1 in patients at T0 to T3 were detected by real-time fluorescence quantitative PCR. Expression of neuropeptide indexes such as neuron-specific enolase (NSE), S100ß protein (S100ß), and amyloid ß-protein (Aß) in serum of patients in the two groups at T0 to T3 were detected by ELISA, and the correlation of expression of serum miR-1, serum NSE, S100ß and Aß was analyzed. There was no significant difference in the expression of serum miR-1 between the two groups at T0 (P>0.05). There was no significant difference in the expression of NSE, S100ß and Aß between the two groups at T0 (P>0.05). Expression of serum NSE, S100ß and Aß in both groups increased gradually, and expression of serum NSE, S100ß and Aß in the intervention group were significantly lower than those in the control group at T1-T3 (P<0.05). There was a positive correlation between expression of serum miR-1, serum NSE, S100ß and Aß (r=0.773, P<0.05; r=0.683, P<0.05; r=0.769, P<0.05). Application of the FTA technology in cardiac surgery can effectively reduce the level of serum miR-1 in patients undergoing surgical treatment and improve their neurological function.
