RESUMEN
Objective To investigate the effects of human umbilical cord mesenchymal stem cells (UC-MSCs) on vascular endothelial growth factor (VEGF) and interleukin-6 (IL-6) expression in acute myocardium infarction (AMI) rats. Methods The human UC-MSCs were cultured to the 4th generation for experiment. Sixty male Sprague-Dawley (SD) rats were randomly divided into sham group, AMI model group and UC-MSCs group, with 20 in each group. AMI animal model was produced by ligation of anterior descending coronary artery; in the sham group, the threading vein was gone below without ligation. In UC-MSCs group 2×106 UC-MSCs were infused through the caudal vein at 24 hours after successful model production. The animals were sacrificed after 7 days; the myocardial tissue and coronary artery below the ligation line were harvested. The mRNA and protein expressions of IL-6 in myocardium were detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western Blot. The positive expression of VEGF in coronary artery was observed by immunohistochemisty. Results Compared with the sham group, the mRNA and protein expressions of IL-6 in myocardium in AMI model group were increased significantly (gray value: 0.732±0.131 vs. 0.321±0.080, 0.678±0.191 vs. 0.286±0.061, both P < 0.05). Compared with the AMI model group, the mRNA and protein expressions of IL-6 in myocardium in UC-MSCs group were decreased significantly (gray value: 0.300±0.104 vs. 0.732±0.131, 0.312±0.101 vs. 0.678±0.191, both P < 0.05). Observation under light microscope, the VEGF positive cells in AMI model group was increased significantly compared with the sham group (cells/HP: 21.1±2.2 vs. 7.6±1.3, P < 0.05), the VEGF positive cells in UC-MSCs group were increased significantly compared with the AMI model group (cells/HP: 41.5±3.1 vs. 21.1±2.2, P < 0.05). Conclusion Human UC-MSCs could promote angiogenesis by the improvement of VEGF in coronary artery and inhibit the inflammation by the reduction of IL-6 in rats with AMI.
RESUMEN
OBJECTIVE:To investigate clinical efficacy and safety of meglumine adenosine cyclophosphate in the treatment of acute myocardium infarction. METHODS:A total of 80 patients with acute myocardium infarction in our hospital during May 2015-Jan. 2016 were selected and divided into control group and observation group according to random number table,40 cases in each group. Control group was given conventional treatment. Observation group was additionally given Meglumine adenosine cyclo-phosphate injection 120 mg added into 5% Glucose injection 250 mL,ivgtt,qd,on the basis of control group. Both groups re-ceived treatment for 7 d. Clinical efficacies as well as the levels of serum hs-CRP and NT-proBNP before and after treatment were observed in 2 groups,and the occurrence of ADR was compared between 2 groups. RESULTS:Total response rate of observation group(92.50%)was significantly higher than that of control group(75.00%),with statistical significance(P0.05). After treat-ment,the serum levels of hs-CRP and NT-proBNP in 2 groups were decreased significantly,and the observation group was signifi-cantly lower than the control group,with statistical significance(P0.05). CONCLUSIONS:Meglumine adenosine cyclophosphate shows significant therapeutic efficacy for acute myocardium infarction,reduces serum levels of hs-CRP and NT-proBNP significantly with good safety.
RESUMEN
Objective To investigate the expression of monocyte subsets and their chemokine,i.e.,monocyte chemoattractant protein (MCP-1) and fractalkine (FKN),in patients with acute coronary svndrome (ACS),and to analyze their correlation.Methods Patients with the syndrome of pectoralgia and to be inspected with coronary angiography (CAG) in our hospital from Sep.to Dec.,2016 were included.Patients' venous blood was collected on the operation day before operation,the level and proportion of monocyte (Mon) subsets,which was namely CD14 + CD16-Mon (Mon1),CD14+CD16 + Mon (Mon2) and CD14-CD16 + Mon (Mon3) according to the expression of cluster differentiation-14 (CD14) and CD16,were detected by flow cytometry (FCM).Patients' venous blood was collected on the operation day before operation and one day after operation,the concentrations of MCP-1 and FKN in plasma were measured by ELISA.We compared the expression levels of MCP-1-Mon1 and FKN-Mon3,and analyzed their relationship between each other respectively in different groups.Results Diagnosed according to the clinical symptoms,myocardial markers,electrocardiogram and CAG results,70 individuals were analyzed,including 30 patients with acute myocardial infarction (AMI group),25 patients with unstable angina pectoris (UAP group) and 15 patients with the chest pain symptoms and normal CAG results (control group).The percentage of Mon1 in the AMI group was higher than that in the other groups (P＜0.05);no difference was observed for Mon3 among the groups (P＞0.05).The Mon3/Mon1 ratio in the AMI group was lower than that in the control group (P＜0.05).Moreover,the levels of FKN and MCP-1 in the ACS group were greater than those in the control group.The level of red blood cell distribution width (RDW) was significantly increased in the AMI and UAP group than that in the control group (P＜0.05).There was a significant correlation between FKN and Mon3 (P＜0.05,R=0.650 2).Conclusions The monocyte subset of Mon1 and Mon3 increased in the early stage of ACS,with their chemokine (FKN and MCP-1) increasing at the same time.There is a significant correlation between FKN and Mon3,which indicates MCP-1-Mon1 and FKN-Mon3 may participate in the pathophysiological process of early ACS in patients.

RESUMEN
Objective To study the effect of psychological nursing on heart rate variability (HRV)in patients with acute myocardium infarction. Methods 80 patients with AMI were randomly divided into group A(routine nursing group)and group B (psychological nursing group) with 40 patients in each group,HRV was evaluated in both groups.The time domain and frequency domain of HRV of 24 h sinus rhythm in two groups of patients were analyzed. Results In group B,24 h average standard deviation of RR interval (SDNN),5 min segments of continuous average standard deviation of RR intervals (SDANN),the difference between adjacent cardiac RR interval of the root mean square (rMSSD),the percentage of adjacent canrdiac RR interval greater than 50 ms (PNN50),low frequency (LF),high frequency (HF) and other HRV parameters were significantly higher than group A. Conclusions Psychological nursing can significantly increase HRV and improve the electric stability of the ischemic myocardium.Psychological nursing can stabilize emotion of patients,decrease sympathetic tone,and may have a role in the prevention of sudden death.
