Generally, most of the follicles undergo atresia during their development in mammals, and only a few grow to maturation and ovulation. For many years, the mechanisms of follicular atresia have been one of the foci of study. Recently, with the development in studies on cell apoptosis, it has been proved that follicular atresia is a process of cell apoptosis. However, the endocrinological and molecular evens underlying follicular development and atresia and granulosa cell apoptosis in the goat has not been studied.

Mineral fuel is the primary energy source in the world today, thereinto coal resource holds in store more than 75 percent in the total energy source. During coal's utilized, nocuousness matter expels into environment through all kings of method and works serious environmental pollution. Desulphurization has become one of primary objects of cleaning coal. At present, there are some primary problems of removing sulfur from coal. It is the size of coal is too small, the time of removing sulfur is too long, the technology is too complicated and the investment is much expensive etal.

The human cartilages are composed of chondrocyte and extracellular matrix , the form of chondrocytes are hypertrophy and the quantity are less; the ECM of cartilage are compised of type Ⅱ collagen and proteoglycan. Articular cartilages are all hyaline with little fibers. Trauma and arthritis are the main cause of cartilage injury, the ommilayer injury ofcartilage can be recovered by marrow, but because of without stimulation mechanism, the new tissues are merely fibrocartilages, they can not be coincide with hyaline cartilage in menchanics; the purely damage of articular cartilage can not stimulate chondrocyte to regenerate because of without blood circulation, thus, the plerosis of articular catilage can not depend on the proliferation of local chondrocyte. Ever since, people tried their best to find a way to reconstruct articular cartilage.
