采用双能X射线吸收术对541名绝经前后妇女进行骨密度测定。结果示:腰椎于30~35岁、股骨近端25~29岁骨密度达到峰值;绝经前没有明显的骨丢失(P>0.05),50岁以后骨密度明显降低(P<0.01);绝经后早期为骨密度加速丢失阶段,随后趋于缓慢;年龄相同而绝经年限不同,骨密度差异显著(P<0.01),绝经年限相同而年龄不同,无显著性差异(P>0.05);多元回归分析表明,绝经年限对骨量丢失的作用强于年龄,认为绝经是女性骨量丢失主要原因。

Objective To investigate the distribution of frequency of parathyroid hormone(PTH) gene polymorphisms in healthy adults of Han nationality in Bejing area and relationship between PTH genotypes and bone mineral density(BMD) in young and postmenopausal women. Methods Polymorphisms of PTH gene were detected by polymerase chain reaction restriction fragment length polymorphism(PCR- RFLP) of restriction enzyme Bst B1 in 270 subjects. If the site of enzyme Bst B1 existed, the PTH genotype was" B" . On the contrary, if base mutation occurred, the genotype was" b" . Some of the PTH genotypes were confirmed by DNA sequences analysis. Bone mineral density(BMD) was measured by dual- energy X- ray absorptiometry. Results Genotype frequencies of BB, Bb, bb were 73.7%, 25.9%, and 0.4% respectively in adults of Beijing areas. The frequencies of RFLP alleles B,b were 86.7% and 13.3% . Beijing postmenopausal women frequencies of BB, Bb, bb were 67.1% , 32.2% and 0.7% . B, b alleles frequencies were 83.2% and 16.8% . We statistically compared bone mineral density at the lumbar 2- 4, neck, wards triangle and trochanter major, there was no significant difference between BB and Bb genotype of young women and postmenopausal women groups. Otherwise, no obvious relationship was found between the BMD and PTH genotype in Beijing women. Conclusions PTH gene polymorphisms were not associateds with BMD in Beijing women .

AIM: To observe the effects of Antai capsule (ATC) on womens post menopausal osteoporosis. METHODS: One hundred and sixty eight women with post menopausal osteoporosis, diagnosed by XR 36 dual energy X ray absorptionetry (DEXA) according to the standard of WHO, were divided randomly into three groups: ATC, Ipriflavone and control. The changes of FSH, LH, E2 and BMD were detected using the radioimmunological assay. RESULTS: Among the 65 patients of ATC treated with ATC, significant effects were found in 48 and good effects in 15, with the total effective rate was 96.9%. Estrogen and BMD obviously increased ( P <0.01). But Ipriflavone had many side effects such as sour regurgitation, discomfort in stomach and hectic fever. CONCLUSION: It is indicated that ATC can increase the level of estrogen and bone mineral density by systematic regulation. Its curative effects were better than that of calcium with vitamin D and Ipriflavone.
