密骨片对PMOP的骨密度、MMP-2及骨代谢指标的影响

目的：观察密骨片(Migu tablet)治疗绝经后骨质疏松症的血清基质金属蛋白酶-2(MMP-2)水平及骨密度(BMD)、骨代谢指标的变化。方法：将年龄55～62岁的192名自然绝经的妇女进行骨密度测定,骨质疏松妇女160例随机分为：密骨片(MG)组68例,仙灵骨葆(XLGB)组50例,钙剂组42例；绝经后正常妇女32例作为正常组。各组均于用药前后12,24周,采用酶联免疫吸附试验(ELISA)测定的血清MMP-2水平、骨碱性磷酸酶(sBAP)、骨钙素(sOC)、Ⅰ型胶原交联C端肽(sCTx)和尿Ⅰ型胶原交联N端肽(uNTx),用双能X线吸收法(DEXA)测定腰椎正位,股骨颈,Ward’s三角和大粗隆的骨密度(BMD)。结果：经治疗后,密骨片组和仙灵骨葆组骨密度均有不同程度的提高,而钙剂组和正常组骨密度均下降；密骨片组和仙灵骨葆组的sBAP,sOC均有明显升高,而MMP-2,sCTx,uNTx明显下降,钙剂组和正常组变化不明显。结论：密骨片治疗绝经后骨质疏松症疗效显著,与仙灵骨葆相仿。单纯服用钙剂不能治疗绝经后骨质疏松症,且继续骨流失。

Effects of Migu tablet on bone mineral density, serum matrix metalloproteinase-2 level and bone metabolic markers in postmenopausal osteoporosis

OBJECTIVE: To study the effects of Migu tablet(MG) on bone mineral density (BMD), serum matrix metalloproteinase-2 (MMP-2) and bone metabolic markers in Chinese postmenopausal women. METHOD: According to the criteria of osteoporosis, 192 Chinese postmenopausal female of the aged 55-62 were randomized into 4 groups, such as the normal, MG group, XLGB group and Leli group. The serum MMP-2, bone alkaline phosphates (sBAP), osteocalcin (sOC), bone cross-linked C-telopeptides of type I collagen (sCTx) and urine bone cross-linked N-telopeptides of type I collagen (uNTx) were measured using ELISA. BMD were measured using dual energy X-ray absorptiometry before and after medication at 12 and 24 weeks. RESULT: After treatment, the values of BMD were significantly higher in MG and XLGB groups separately, otherwise lower in Leli and normal control groups. At the same time, serum MMP-2, sCTx, uNTx/Cr concentrations were significantly lower and sBAP, sOC concentrations were higher, but the concentrations in Leli and normal control groups were basically same to the value of before treatment. CONCLUSION: The effects of MG tablet to treat the PMO were notable, just same to XLGB. But calcium tablet cannot play a role in the treatment of osteoporosis and do not prevent the loss of bone.
