Correlation analysis for follicle-stimulating hormone and C-terminal cross-linked telopetides of type i collagen in menopausal transition women with osteoporosis.

The sudden drop in estrogen in post-menopausal women can lead to osteoporosis. About one in three women aged more than 50 years experienced an osteoporotic fracture. The aim of this study is to explore function of follicle-stimulating hormone (FSH) in bone metabolism and osteoporosis in menopausal transition women. 164 cases of women in menopausal transition were included, and which were divided into three groups, including < 40 years group, 40-50 years group and > 50 years group. All of patients must with empty stomach, and 5 ml blood was collected from median cubital vein between second day to ninth day in menstruation period. Examination of FSH and C-terminal cross-linked telopetides of type I collagen (CTx) was performed by using ECLIA assay. The results indicated that CTx levels were distinguished among the different aged group, with the increasing level following with the increased age. FSH level in both of < 40 years and 40-50 years old women were positively correlated with CTx level (P < 0.05). The spearman rank correlation analysis results also showed that there were no significant correlation between CTx level and FSH level in > 50 years old women. There were significant differences for the CTx level between 0-40 mIU/ml group and > 40 40 mIU/ml group in all of the three ages group (P < 0.05). In conclusion, it's clinically significant for the combining examination of FSH and CTx in menopausal transition women, which could observe the bone metabolize changes quickly and sensitively, and prevent or therapy the osteoporosis in a further step.
