Objective :To explore therapeutic effect of recombinant human brain natriuretic peptide (rhBNP) and le‐vosimendan on patients with acute myocardial infarction (AMI) undergoing emergency percutaneous coronary inter‐vention (PCI) and its safety .Methods :A total of 110 AMI patients undergoing PCI ,who were treated in our hospi‐tal from Jan 2017 to Oct 2017 ,were selected .Patients were randomly divided into rhBNP group (n＝53 ,received rhBNP based on routine medication ) and levosimendan group (n＝57 ,received levosimendan based on routine medi‐cation) ,both groups were treated for 7d.The 24h urine volume ,heart rate (HR ) ,respiratory rate (RR ) before and 24h after PCI ,level of brain natriuretic peptide (BNP) , LVEF , LVEDd ,LVESd before and 7d after PCI were observed and compared between two groups .Results : Compared with before PCI on 24h after PCI ,there was significant rise in 24h urine volume ,and significant reductions in HR and RR in two groups , P＝0.001 all.Com‐pared with levosimendan group on 24h after PCI ,there was significant rise in 24h urine volume [(1732.00 ± 243. 75) ml vs.(1854.23 ± 264.24) ml] ,and significant reductions in HR [ (79.24 ± 9.43) beats／min vs.(73.43 ± 8.24) beats／min] and RR [ (18. 32 ± 4. 76) times／min vs.(15.32 ± 4. 23) times／min ] in rhBNP group ( P＜0. 05 or ＜0.01) ;on 7d after PCI ,compared with rhBNP group , LVEF [ (40.45 ± 5. 65)% vs .(44.75 ± 5.87)%] , BNP lev‐el [(256. 54 ± 9.38) pg／ml vs.(395.25 ± 8. 34) pg／ml] was significantly higher ,and LVESd [(47. 87 ± 4.65) mm vs.(43. 83 ± 3.65) mm] were significantly lower ( P＝0.001 all) in levosimendan group .There was no significant difference in incidence rates of adverse reactions between two groups after PCI ( P＞0.05 all).Conclusion :Myo‐cardial contraction capacity of levosimendan is significantly better than that of rhBNP ,while rhBNP is significantly better than levosimendan in reducing BNP level and improving renal function .

" Day surgery hospital-community joint follow-up model " results newly from the deepening implementation of the hierarchical medical system policy. It is designed to follow up the patients discharged from hospital but not fully recovered in time to ensure the prevention of adverse events after surgery. It can also improve the quality and efficiency of follow-up, and ensure the safety and integrity of the whole day operation management. In this context, through a comparative study of 720 patients discharged from daytime surgery in the region, patients in the combined follow-up group were followed up by telephone on the 3rd day after the operation by nurses from the day surgery ward. On the 10th and 20th days after the operation, the family doctor from the community health service center will visit the patient at home and follow up the patient by telephone. One month later, the patient returned to the hospital for follow-up consultation. Follow-up results show day surgery hospital-community joint mode as a helpful aid in keeping track of the patients postoperative rehabilitation, reducing complications and handling in time, while improving the ambulatory surgery perioperative safety.
