As one of the big emerging markets, China's enormous population and rapid increase in consumer spending have attracted many multinational corporations (MNCs). Meanwhile, the misconception of China as a homogeneous market often leads to difficulties in assessing market demand and enacting effective strategies. Examines the diversity among Chinese consumers across seven regional markets. Data from a national survey suggest that consumers from various regions are significantly different from one another in terms of purchasing power, attitudes, lifestyles, media use, and consumption patterns. MNCs need to take a cautionary approach when expanding into the inland regions, and must adapt to the local market conditions and devise sustainable strategies.

How to integrate the emerging consumer segments in transitional economies into multinational corporations’ global marketing strategies presents a significant challenge. An analysis of China's urban consumers based on a 1997 national survey reveals several market segments that are distinctive in their demographics, psychographics, lifestyles, media usage, and consumption patterns. The findings suggest that multinational corporations need to adapt to the local market conditions in China and other transitional economies.

Cardiac involvement has been reported in patients with COVID-19, which may be reflected by electrocardiographic (ECG) changes. Two COVID-19 cases in our report exhibited different ECG manifestations as the disease caused deterioration. The first case presented temporary SIQIIITIII morphology followed by reversible nearly complete atrioventricular block, and the second demonstrated ST-segment elevation accompanied by multifocal ventricular tachycardia. The underlying mechanisms of these ECG abnormalities in the severe stage of COVID-19 may be attributed to hypoxia and inflammatory damage incurred by the virus.
