| 目的 应用LC-MS法筛选分析强骨饮治疗后绝经后骨质疏松症患者和未治疗绝经后骨质疏松症患者 全血差异蛋白，探索强骨饮治疗绝经后骨质疏松症的作用机制。方法 本研究采用液相色谱-串联质谱联用测定法分别对7例强骨饮治疗后绝经后骨质疏松症（治疗组）患者及8例未治疗绝经后骨质疏松症（未治疗组）患者全血蛋白进行检测,并对差异蛋白质进行定量分析,筛选出差异蛋白，进行生物信息学分析。结果 分析治疗组与对照组患者全血共筛选出差异蛋白91个, 以差异倍数大于1.2 倍作为显著上调、小于0.83作为显著下调,有 31个蛋白表达显著上调,60个蛋白表达显著下调。对所有差异蛋白进行GO功能注释分析，发现上调的差异蛋白主要位于细胞质内，而下调蛋白有22 %在细胞外，有 1个细胞骨架蛋白。差异蛋白参与的主要细胞活动为单一生物过程、细胞代谢过程等，分子功能主要为催化活性、分子功能调节剂和结构分子活动等。结论 LC-MS法能有效筛选出强骨饮治疗的PMOP患者和未治疗的PMOP患者全血中的差异蛋白，强骨饮治疗PMOP的作用机制是一个由多种蛋白质分子参与的结果,其关键的靶标和具体的调控机制尚待进一步的研究加以探索及验证。 |

| Objective:To screen the differential protein of Qiangguyin in the treatment of postmenopausal osteoporosis, and to explore the mechanism of Qiangguyin in the treatment of postmenopausal osteoporosis.Methods:In this study, the whole blood protein was detected by liquid chromatography-tandem mass spectrometry in the treatment group (n=7) and the control group (n=8), and the differential proteins were quantitatively analyzed. Results ：A total of 91 differential proteins were screened from the whole blood of Qiangguyin treatment group and control group. Among them, 31 proteins were significantly up-regulated and 60 proteins were down-regulated significantly. GO function annotation and functional analysis were performed on all identified proteins, and it was found that the up-regulated differential proteins were mainly located in the cytoplasm, almost all in the cells, while 22% of the down-regulated proteins were outside the cell, 36% were in the cytoplasm, and 1 cell was present. Skeletal protein. The main activities involved in differential proteins are single biological processes, metabolic processes, biological regulation, and responses to stimuli. The molecular functions are mainly catalytic activity, molecular function regulators and structural molecular activities.Conclusion：LC-MS can effectively screen out the differential protein of Qianggu Decoction in the treatment of PMOP. The mechanism of Qiangguyin in the treatment of postmenopausal osteoporosis is the result of a variety of protein molecules involved, its key targets and specific regulation. The mechanism needs to be further explored and verified. |
