The biocatalyzed characters of the purified cellulases were investigated with the CMC-Na as substrate. The most appropriate catalyzed temprature for cellulase 1 is 60 "C,and 65 for cellulase 2. The two enzymes have the extreme stability at the temperatures no more than 50.The CMC-Na has the protective effect on the cellulase. The pH stability range of cellulase 1 is 4 ~ 8, and 6-9 for cellulase 2. Zn2+, Ca2+, Mg2+, K+, Li+can ativate cellulase 1. K+, Li"1 can ativate cellulase 2. Cellulase 1 can mainly decompose CMC and salicin. Cellulase 2 can decompose not only CMC and salicin, but other substrates feebly.

Base on core observation and grain size analysis, and under associated consideration of logging trace characteristics, Chang8 reservoir in study area is classified into three sedimentatal microfacies, subsea river, mouth bar and river flank.3.The mian diagenesis in study area are: mechanical compaction, cementation, metasomasis and denudation in late diagenetic phase.4. In allocation of reservoir macroscopic heterogeneity, more heterogeneticer reservoir, class 1 and class 2, mainly locate in the center of subsea river or crook and divaricate of the river; class 3 and class 4 mainly locate in river flank, and the physical property of these locality are better.5. Diagenesis of reservoir have influence on the pore structure which influences the reservoir microscopic heterogeneity. The better the pore structure is, the slighter the reservoir microscopic heterogeneity is; on the contrary, the reservoir microscopic heterogeneity is serious.

Estrogen deficiency can increase the mRNA expression of MMP-1、MMP-3 and IL-1β in OA synovia tissue. Estrogen could inhibit the mRNA expression of MMP-1、 MMP-3 and IL-1β in OA synovia tissue. Progestin could even decrease this expression. Estrogen could slightly increase the mRNA expression of TIMP-1. It is suggested that low dose of estrogen supplement play a protective effect on OA cartilage, and progestin could increase this protective effect.
