This decline in hormones has been associated with changes such as depression, loss of libido, sexual dysfunction, and changes in body composition. Aging has been associated with an abundance of concomitant diseases, in particular cardiovascular diseases, and although andropause is correlated to aging, a causal relationship between reduction of androgens and the development of chronic diseases such as atherosclerosis and heart failure has not been convincingly established yet. On the other hand, increasing data has emerged that revealed the effects of low levels of androgens on cardiovascular disease progression. As an example, low levels of testosterone have been linked to a higher incidence of coronary artery disease. Whether hormone replacement therapy that is used for andropausal men to alleviate symptoms of ＂male menopause＂ can halt progression of cardiovascular disease, remains controversially discussed, primarily due to the lack of well-designed, randomized controlled trials. At least for symptom improvement, the use of androgen replacement therapy in andropausal men may be clinically indicated, and with the appropriate supervision and follow up may prove to be beneficial with regard to preservation of the integrity of cardiovascular health at higher ages.展开更多

The 1st and 2nd groups were normal estrous and ovariectomy (OVX) controls. Treatment of the other groups imitated the clinical regimen (continuous and cyclic) with estradiol valerate (E2V) and medroxy progesterone (MPA) in different ratios of combination. The rats were sacrificed and sections of uterus were stained with HE and histochemical metheds to detect mitosis and proliferating cell nuclear antigen (PCNA), respectively. The mitotic index (MI) and PCNA index were calculated.Results The MI and PCNA index were similar in luminal and glandular cells. Both markers were low in the two control groups. When E2V was given for 1 to 6 days, both the MI and PCNA index increased with duration of treatment. When MPA was added, both markers were reduced to a very low level. In the continuous regimen, both markers decreased as the MPA dosage increased. The ratio of E2V∶MPA=1∶0.5 was enough to suppress markers to a low level similar to that of normal estrous rats. A further increase in the ratio to 1∶1.0 showed no further decrease in PCNA index. In the cyclic regimen, MPA was added for the last 5 days. The mitotic index reached a significantly low level near 0 in all ratios, but the PCNA index in each subgroup was still as high as the positive control, even though the dosage of MPA was increased several times to 1∶8.0. When MPA was added for the last 10 days, the PCNA index at a ratio of 1∶4.0 could be reduced to a low level.Conclusion The results of this study suggest that the continuous regimen was better than the cyclic regimen in postmenopausal hormone replacement therapy (HRT). Progestin should be given for at least 10 days in the cyclic regimen.展开更多

The rational drug management system of Ningbo Women and Children’s hospital was used to screen the prescriptions of menopausal syndrome in 4 years. After the age, year included in the study, and prescription cost were adjusted, Kaplan-Meier regression analysis was performed to compare the prescription retention rates of the two drug regimens. The distribution of the two HRT regimens in the 4 years showed an increasing trend year by year, and the age groups of the two HRT regimens were mainly distributed between 41 and 60 years old, accounting for 97.1% and 87.06%, respectively. The cost distribution for the other two HRT regimens was approximately the same. Compared with the two HRT regimens, the drug retention rate of hormone continuous regimens was higher than that of hormone sequential regimens within 4 years. Kaplan-Meier regression analysis showed that the trend was significant(Tarone-Ware, Chi-square value = 3.857, P = 0.050). This study found that the median retention time of HRT therapy in menopausal women in our hospital was about half a year, which was significantly lower than that reported in previous studies of 1 year or longer. In addition, the present study found that compared with Femoston, the tibolone regimen significantly increased retention time in the treatment of menopausal syndrome.展开更多
