The aim of this study was to examine the relationship between serum concentration of testosterone and mortality in men with systolic CHE Methods A total of 175 elderly (age ≥ 60 years) men with CHF were recruited. Total testosterone fiT) and sex hormone binding globulin (SHBG) were measured, and free serum testosterone (eFT) was calculated. The median follow-up time was 1262 days. Results During follow-up 54 (30.9%) patients died. TT and eFF deficiency was found in 21.7% (38/175) and 27.4% (48/175) patients, respectively. Both TT and eFT were inversely associated with LVEF and NT-proBNP (all P〈0.01). Kaplan-Meier curves for patients in low, medium and high tertiles according to TF and eFT level showed significantly different cumulative survival rate (both P〈0.01 by log-rank test). However, after adjustment for clinical variables, there were no significant associations between either Tr or eFT levels or survival time (OR=0.97, 95% CI, 0.84-1.12, P--0.28; and OR=0.92, 95% CI, 0.82-1.06,/'=0.14, respectively). Conclusion Our study showed that although levels of TT and eFT are commonly decreased in elderly patients with systolic CHF and related to disease severity, they are not independent predictors for mortality展开更多

Methods: A total of 40 SPF-SD female rats(5–6 week-old) were randomly divided into three groups: blank control group(group A), castration control group(group B) and transplant group(group C). Ovaries were removed by surgical procedure, then after cryopreservation and thawing procedures the ovarian tissues were implanted into the back muscles of mice in group C. After 4 weeks of ovarian tissues transplantation, all rats blood sampling were measured for E2, LH and FSH hormone levels by ELISA. Results: E2 level was significantly higher in group C and group A than group B [(38.98 ± 5.66) pg/mL,(8.14 ± 3.24) pg/mL; P < 0.05) and [(36.30 ± 6.90) pg/mL,(8.14 ± 3.24) pg/mL; P < 0.05)]. However, E2 level in group C and group A had no significant difference. FSH level in group B, group A and group C was(18.87 ± 2.54) nmol/L,(7.77 ± 0.87) nmol/L and(9.39 ± 2.12) nmol/L respectively. FSH level increased significantly in group B compared with group A, and the difference had statistical significance(P < 0.05). FSH level was slightly increased in group C compared with group A, and the difference was not statistically significant(P > 0.05), but compared with group B, FSH level was significantly reduced and being statistically significant(P < 0.05). Conclusion: Autotransplantation of cryopreserved-thawed ovarian tissue into back muscles can sustain follicular development and re-establish endogenous hormone production by restoring the factors such as angiogenesis and innervations at the graft site.展开更多

The serum testosteron e concentrations of 28 volunteers were investigated daily during abstinence peri ods after ejaculation for two phases. The authors found that the fluctuations o f testosterone levels from the 2nd to 5th day of abstinence were minimal. On the 7th day of abstinence, however, a clear peak of serum testosterone appeared, re aching 145.7% of the baseline (P<0.01). No regular fluctuation was observed foll owing continuous abstinence after the peak. Ejaculation is the precondition and beginning of the special periodic serum testosterone level variations, which wou ld not occur without ejaculation. The results showed that ejaculation-caused va r iations were characterized by a peak on the 7th day of abstinence; and that the effective time of an ejaculation is 7 days minimum. These data are the first to document the phenomenon of the periodic change in serum testosterone level; the correlation between ejaculation and periodic change in the serum testosterone le vel, and the pattern and characteristics of the periodic change.展开更多
