Differences in symptoms and pre-hospital delay among acute myocardial infarction patients according to ST-segment elevation on electrocardiogram: an analysis of China Acute Myocardial Infarction (CAMI) registry.
Approximately 70% patients with acute myocardial infarction (AMI) presented without ST-segment elevation on electrocardiogram. Patients with non-ST segment elevation myocardial infarction (NSTEMI) often presented with atypical symptoms, which may be related to pre-hospital delay and increased risk of mortality. However, up to date few studies reported detailed symptomatology of NSTEMI, particularly among Asian patients. The objective of this study was to describe and compare symptoms and presenting characteristics of NSTEMI vs. STEMI patients. ⋯ Patients with NSTEMI were more likely to present with chest distress and pre-hospital patient delay compared with patients with STEMI. It is necessary for both clinicians and patients to learn more about atypical symptoms of NSTEMI in order to rapidly recognize myocardial infarction.

Anti-inflammatory effects of Eucommia ulmoides Oliv. male flower extract on lipopolysaccharide-induced inflammation.
Eucommia ulmoides Oliv. is a medicinal plant native to China, with its bark (Eucommiae Cortex) traditionally being used for medicinal purposes. Previous research has shown that Eucommia male flowers can exert anti-inflammatory, analgesic, antibacterial, and other pharmacological effects, including immune regulation. This study explored the anti-inflammatory effects of the 70% ethanol extract of male flowers (EF) of E. ulmoides in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells and LPS-administered mice. ⋯ EF could effectively inhibit the expression of inflammatory factors and overactivation of neutrophils. Further investigation is needed to evaluate its potential for anti-inflammation therapy.
