Study on the Effect of Bushen Zhuanggu Tablet Combined with Conventional Regimen on Bone Mineral Density Improvement, Functional Recovery and Fracture Risk Prevention in Patients with Postmenopausal Osteoporosis

Abstract

Objective. This case-control study was to explore the effect of Bushen Zhuanggu tablet combined with routine regimen on bone mineral density (BMD) improvement, functional recovery, and fracture prevention in postmenopausal osteoporosis (PMOP) patients. Methods. 180 postmenopausal osteoporosis patients were randomly selected from communities A, B, and C cohorts as research subjects from January to May 2021. The study subjects were divided into three groups. The groups were in a 1 : 1 ratio according to the principles of nonrandomised, concurrent controlled trials, and methods. There were 60 participants in each group (group A, group B, and group C). Group A was treated with Bushen Zhuanggu tablet for antiosteoporosis + basic treatment (calcium supplement and vitamin D). Group C was given Bushen Zhuanggu tablet for antiosteoporosis intervention. Group B was given basic treatment (calcium supplement and vitamin D supplementation) as a control group. The follow-up time was 6 months after treatment. Finally, we compare the differences in calcium and phosphorus metabolism indexes, BMD, bone metabolism indexes, upper and lower limb muscle strength, and quality of life scores. Results. Group A, B, and C’s effective rate was 98.33%, 80.00%, and 93.33%, respectively. The group A’s effective rate was significantly higher than that in group B and C, and the difference was statistically significant ( $P<0.05$ ). After 6 months intervention, the levels of serum Ca2+, serum phosphorus (P), serum creatinine (Cr), and parathyroid hormone (PTH) in 3 groups decreased. Ca, P, Scr, and PTH levels in group A were the lowest among study groups, and the difference was statistically significant ( $P<0.05$ ). The increase in the BMD of lumbar spine, the left femoral neck, and Ward’s triangle area of the three groups were observed with the highest data in group A. After 6 months of treatment, the levels of serum N-terminal propeptide of type I procollagen, PINP, and serum osteocalcin (OC) increased, while the levels of β-cross-linked C-terminal telopeptide of type I collagen (β-CTX) and alkaline phosphatase (ALP) decreased in the three groups. The improvement of all bone metabolic indexes in group A was significantly better than that in B and C groups, and the difference was statistically significant ( $P<0.05$ ). The enhanced upper limb muscle strength and the shorter standing-walking timing test (TUGT) time were observed after 6 months of treatment. The improvement effect of upper and lower limb muscle strength in group A was significantly better than that in B and C groups, and the difference was statistically significant ( $P<0.05$ ). There were significant differences in physiological function, life function, general health status, physical pain, mental state, emotional function, vitality, and social function among the three groups after 6 months treatment, and the difference was statistically significant ( $P<0.05$ ). The score of quality of life in group A was higher than that in B and C groups, and the difference was statistically significant ( $P<0.05$ ). Conclusion. Bushen Zhuanggu tablet combined with conventional therapy is effective in the postmenopausal osteoporosis treatment, which effectively increase the BMD, regulate calcium and phosphorus metabolism, promote the recovery of limb function, prevent the recurrence of fracture, and improve the patients’ quality of life. This treatment scheme is worth popularizing.
