Ave rage serum E 2 level of women with or without cyclic breast pain in luteal phase were365.0pmol/L and335.3pmol/L respectively (P>0.05),serum progesterone level were73.3nmol/L and66.1nmol/L respectively(P>0.05).
Compared with the model group,the bone shape of treatment group improved significantly,the bone density and serum E 2 level increased while the serum TNF-αlevel lowered(P<0.05or P<0.01)to a level close to that of the sham op-eration group.
Average serum E 2 levels of women with or without breast structure change in luteal phase were368.1pmol/L and322.7pmol/L respectively(P<0.05). Serum P levels were78.8nmol/L and62.2nmol/L respectively(P=0.05);
Serum E2 levels at the third day and at the pick up oocyte day in control group were 14±5pg/ml and1842±675pg/ml, respectively（P<0.01）. Accordingly, PCOS group were 15±7pg/ml and 2282±709pg/ml, respectively（P<0.01）.
Methods: The basal body temperature (BBT) , the thickness and echopattem of endometrium, the biggest diameter of dominant follicle, the level of serum E2 and the cervical scoring of 75 pregnancy cycles of IVF - ET (including 37 conventional IVF cycles and 38 ICSI cycles) were observed.
(3) the level of serum E2 was significantly higher, but the level of serum T was rnarkedly lower in CR rats than that in AL ones at most time point during 24 hours. Meanwhile, CR rats had markedly higher ratio of E2 to T than control group.
Conclusions The high level of serum E 2 and over-expression of ER and PR in gallbladder may play an important role in onset and development of GBC. So they are of value for potential application in early diagnosis of GBC.
Results Serum E 2 concentrations were significantly higher and serum T levels were lower in patients with different age (20～29) years, ～39 years, ～49 years and ～70 years) than those of age-matched contrl group ( P <0 01).
