Objective:
To investigate the effect of Jianpi Bushen (JPBS) formula on aromatase inhibitor (AI)-associated bone loss after menopause.
Methods:
Six-month-old female rats were randomly divided into 6 groups: a sham group, an ovariectomized (OVX) group, an OVX treated with exemestane and 3 OVX groups each treated with a different dose of JPBS formula. Bone mineral density (BMD) at the lumbar vertebrae, histology, bone markers and serum levels of estrogen were assessed. Furthermore, a cohort study was conducted in 130 postmenopausal women with breast cancer that had undergone treatment with AIs. The subjects were given JPBS + caltrate D or caltrate D only, administered orally. BMD at the lumbar vertebrae and femoral neck and bone markers were evaluated in both control and herbal treatment groups at baseline and 12 months.
Results:
Experimental results indicated that a high dose of JPBS significantly increased the trabecular bone area percentage (Tb.Ar %) and broadened the trabecular thickness (Tb.Th). The JPBS formula enriched the carboxyterrninal propeptide of type ipmcollagen and increased serum estrogen level significantly. The clinical investigation revealed that bone loss was decreased in the group treated with JPBS vs control (BMD T score at lumbar vertebrae, 3.9% increased vs 14.58% decreased, respectively, P = 0.004 and BMD T score on femoral neck, 1.8% decreased vs 22.45% decreased, respectively, P = 0.008). Besides, JPBS formula elevated N- middle osteocalcin and decreased type I collagen cross-linked C-terminal telopeptide.
Conclusion:
JPBS formula prevented aromatase-inhibitor-associated bone loss after menopause by inhibiting bone resorption and promoting bone formation.

01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:22Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
