Arthritis is widely viewed as "nonfatal cancer". Patients with arthritis suffer for years from joint pains, tumefactions and distortions. Severe arthritis can even disable some patients. According to the 06' National Annual Conference of Rheumatism, there are over 100 million patients with arthritis in China. With the fast aging population in China, the incidence of arthritis is increasing dramatically. However, most made medicines and operations provided by domestic hospitals are usually inefficient and often have many negative side effects.

Based on the combination of its researches and practices for decades of years, SPRC designs this class to provide common people with basic medical knowledge about arthritis, and help them relieve frequent symptoms. The class also includes numerous operative suggestions.
