Intraspecific variation in metabolic rate and its correlation with local environment in the Chinese scorpion .

Scorpions are well known for their reduced resting metabolic rate (RMR) in comparison to typical arthropods. Since RMR is a key physiological trait linked with evolutionary fitness, it is expected that there may exist intraspecific RMR variation given the ecological and geographical heterogeneities across the distributional range of a species. Nevertheless, it is unclear whether RMR variation exists among scorpion populations.

Brief Introduction of Medical Insurance System in China.

China has one of the largest numbers of cancer patients. The huge expenses of medical care for cancer patients has brought heavy economic burden to the family. This paper briefly introduces the tumor medical insurance situation in China from the construction and composition of China's medical security system, the access of cancer patients to get health insurance, the challenges and developmental trend of China's medical security system, and two case studies that highlight different financial situations.
