With the development and popularity of percutaneous coronary intervention (PCI), ischemia-reperfusion injury (IRI) has attracted more and more clinical attention. Reperfusion arrhythmia (RA), one of the common manifestations during and after PCI, can affect the postoperative cardiac function of patients with acute myocardial infarction (AMI). Therefore, effective intervention on RA has important clinical significance. This study observed the effect of amiodarone on reperfusion arrhythmia (RA) after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) and explored its possible mechanism. The results showed that amiodarone had good clinical efficacy in the prevention of RA in patients with AMI after PCI, and it could reduce the levels of serum IL-6, hs-CRP, CK-MB, and cTnI in patients and reduce the damage caused by reperfusion, thereby reducing the occurrence of RA.

Data sharing and information exchange among medical institutions is a requirement for convenient and effective data availability for both healthcare professionals and patients. In this paper, the characteristics of medical data are studied; two mainstream technologies of data storage for medical information are compared, and three strategies of medical documents storage are described with detailed advantages and disadvantages. Semi-structured storage technology is easier to deploy and much more promising to promote in a wider range than all-structured methods. The combination of central and distributed data storage is more practical for regional data sharing. This analysis suggests that semi-structural data storage technology and the combination of central and distributed data storage are efficient and fit well the current situation in China.

The objective of this study was to share the experience of building an information security system for a regional collaborative medical platform (RCMP) and discuss the lessons learned from practical projects. Safety measures are analyzed from the perspective of system engineering. We present the essential requirements, critical architectures, and policies for system security of regional collaborative medical platforms.
