Objective To investigate the effect of early life stress on the locomotion and concentration of corticosterone in peripheral blood in adult rats.Methods Maternal deprivation and isolation were used in the model of early life stress. Chronic stress was used in adult rats.Open field test was used for the measurement of locomotion activity. ELISA was used to measure the concentration of corticosterone in peripheral blood.Results The total activity time of locomotion[(296.96±6.63)s, (291.06±8.40)s;P<0.01] and the concentration of corticosterone [(15.51±2.41)nmol/L,(11.27±2.49)nmol/L;P<0.05]were increased in adult rats by maternal deprivation. The total activity distance [(23231.29±2030.35)mm,(14042.81.06±2875.34)mm;P<0.05] and time[(296.39±3.48)s,(259.18±4.71)s;P<0.01]were increased after chronic stress which was used in adult rats in which maternal deprivation were used before. The concentration of corticosterone[(20.60±1.83)nmol/L,(14.49±1.37)nmol/L;P<0.01]was also increased in the same condition.Conclusions The concentration of corticosterone and locomotion activity of adult rats can be increased by early life stress. The reaction of HPA axis for chronic stress was improved by early life stress.

Objective To investigate the relationship between insulin resistance and endogenous androgens at early and late phase of postmenopause.Methods A total of 105 women with early postmenopause (≤5 years since menopause) and 107 women with late postmenopause (≥ 10 years since menopause) were enrolled in this study.In the mean time,those women were classified into normal weight [body mass index (BMI),BMI <24 kg/m2] group and overweight (BMI≥24 kg/m2) group.Sex hormonebinding globulin (SHBG),testosterone (T),dehydroepiandrosterone-sulfate (DHEA-S),fasting blood glucose(FBG),fasting insulin (FINS)levels were measured and then calculated free androgen index(FAI) and homeostatic model assessment of insulin resistance (HOMA-IR).The relationship between sex hormones and insulin resistance was analyzed by partial correlation and multiple linear regression analyses.Results Compared to early postmenopausal women,late postmenopausal women had higher FINS [(7.9 ± 6.6) mU/L versus (6.6 ±4.0) mU/L] and HOMA-IR(2.1 ± 1.9 versus 1.7 ± 1.1),but they had lower DHEA-S [(0.9 ± 0.5) mg/L versus (1.1 ± 0.5) mg/L,all P < 0.05)].Both in early postmenopausal and late postmenopausal groups,overweight women had higher HOMA-IR (early group,2.2 ± 1.0 versus 1.2 ±0.9 ; late group,2.8 ± 2.6 versus 1.6±1.1)and FINS early group[(6.9±2.9) mU/L versus (4.6±2.0) mU/L] ;late group [(10.2 ± 9.3) mU/L versus (6.4 ± 3.6) mU/L] than those at women with normal weight group(all P < 0.05).In early postmenopausal group,overweight women had lower SHBG [(52 ±37) nmol/L versus (71 ±37) nmol/L] and higher FAI(2.5 ±2.1) versus (1.3 ± 1.1) than those at normal weight women group(all P < 0.05).In late postmenopausal group,overweight women had higher DHEA-S (1.0 ± 0.5) mg/L versus (0.8 ± 0.4) mg/L (P < 0.05).The analyses suggested that in early postmenopausal group,SHBG was correlated negatively with FINS and HOMA-IR (β =-0.386,P < 0.05 ;β =-0.553,P <0.05),DHEA-S was correlated positively with FBG (β =0.348,P < 0.05) in early postmenopausal group.FAI was correlated positively with FBG in late postmenopausal group (β =0.505,P < 0.05).Conclusions The increased androgenic activities are associated with insulin resistance after of menopause.These correlations are different at different stages of postmenopause,which SHBG levels correlate with high risk of insulin resistance and DHEA-S levels correlates with high blood glucose levels at early postmenopause and FAI correlates with high blood glucose levels at late postmenopause.
