Osteoporosis and the resulting fractures have become serious global problems. In the United States, about 1.2 million patients are diagnosed with osteoporosis each year. The cost of treatment is US$7.0 billion to US$12 billion, accounting for 85% of the cost of treating all fractures in the United States[1]; approximately 1/3 of the population aged over 65 in Japan. People suffer from osteoporosis; there are about 80 million osteoporosis patients in China, and more than 100 million people need to take preventive measures [2]
