“…Alkaline phosphatase is mainly derived from osteoblasts and participates in inhibiting bone mineralization, increasing bone mass, and enhancing bone metabolism [52]. Inadequate P intake can promote the secretion of parathyroid hormone to improve the proliferation of osteoblasts, which results in a great deal of ALP entering the blood, thereby increasing the serum activity of ALP [53]. In this study, a lower serum ALP activity was observed in the MCP group, which is in agreement with previous reports [54,55].…”

Reproductive efficiency is the main factor limiting yak production on the Tibet Plateau. The purpose of this study was to investigate the effect of supplementation with calcium chloride (CaCl) and monocalcium phosphate (MCP) for 30 days before breeding on body weight (BW) change, serum bone metabolism biomarkers, conception rate, and calving rate of grazing yaks. Ninety 3 year old yak heifers (153.05 ± 6.56 kg BW) were assigned to three treatments (n = 30 per treatment): grazing without supplementation (CONT), grazing plus calcium chloride supplementation (CaCl), and grazing plus monocalcium phosphate supplementation (MCP). Compared with the CONT group, supplementation with CaCl increased the serum concentrations of osteocalcin and decreased the alkaline phosphatase (ALP) levels (p < 0.05); supplementation with MCP increased the average daily gain (ADG), serum concentrations of phosphorus (P) and osteocalcin, conception rate, and calving rate (p < 0.05), whereas it decreased the serum concentrations of hydroxyproline, ALP, and calcitonin (p < 0.05). Both CaCl and MCP supplementation had no effect on serum calcium (Ca) concentration. The ADG, conception rate, and calving rate were higher in the MCP group than in the CaCl group (p < 0.05), while the serum concentrations of hydroxyproline and calcitonin were lower (p < 0.05). It could be concluded that premating supplementation with MCP increased the body weight gain and subsequent conception and calving rate of grazing yaks. Supplementation with MCP had a positive effect on body condition and bone metabolism, thus providing a better estrous condition for grazing yak heifers, which could contribute to enhancing reproduction efficiency.

“…This protein can not only reflect the activity of osteoblasts but also inhibit the activity of osteoclasts and prevent bone loss [ 17 ]. PICP can reflect the synthesis rate of type I collagen and indirectly reflect the activity of bone cells and bone formation, which is conducive to the evaluation of postoperative rehabilitation of patients [ 17 , 18 ]. TRAP-5b is a glycoprotein secreted by activated macrophages, osteoclasts, and dendritic cells.…”

Objective. This work is organized to analyze the clinical effects of new shoulder joint abduction frame on the bone metabolic markers, shoulder joint function, and visual analogue scale (VAS) of humeral fracture patients undergoing arthroscopic surgery. Methods. 118 patients with humeral fracture who planned to undergo shoulder surgery in our hospital from November 2018 to June 2021 were selected as the study objects and were divided into two groups according to the random number method, with 59 patients in each group. The patients in the two groups were subjected to arthroscopic shoulder surgery. New shoulder joint abduction frame was used for shoulder joint fixation in the abduction frame group, and sling was used for shoulder joint fixation in the sling group after surgery. The duration of fixation was 4-6 weeks. Finally, the prognostic indicators, complications, and serum bone metabolism levels in 4 and 6 weeks after surgery, shoulder joint function (Neer score), VAS score before surgery and after 3 and 6 months of surgery, and excellent or good rate of shoulder joint activity after 6 months of surgery were compared between the two groups. Results. The postoperative fracture healing time and start time of shoulder joint training were shorter, and the humeral varus angle and femur height loss were smaller in the abduction frame group than in the sling group ( P < 0.05 ). There was no significant difference in the total incidence of complications between the two groups (3.39% and 13.56%, respectively) ( P > 0.05 ). After 4 or 6 weeks of surgery, the levels of serum osteoprotegerin (OPG) and carboxyterminal propeptide of type I procollagen (PICP) were increased but the levels of tartrate-resistant acid phosphatase-5B (TRAP-5B) were decreased in the two groups with more significant differences in the abduction frame group ( P < 0.05 ). After 6 months of follow-up, 2 cases were lost to follow-up in the abduction frame group and 3 cases in the sling group. Neer scores were increased, while VAS scores were decreased in the two groups in the third or sixth months after surgery with significant differences in the abduction frame group ( P < 0.05 ). The excellent or good rate of shoulder joint activity was 94.74% (54/57) in the abduction frame group, significantly higher than that in the sling group (80.36%; 45/56) ( P < 0.05 ). Conclusion. The fixation effect of new shoulder joint abduction frame is significant after arthroscopic surgery, and patients can carry out functional training as early as possible, which is helpful to promote fracture healing, relieve pain, and restore shoulder joint function with high safety.

“…The cytological changes of aging bone reduce the number of osteoblasts available in bone remodeling and bone formation. Although the process of senile osteoporotic bone loss is the common result of the changes in hormone and bone cell structures, some cases of bone mass loss are just at the physiological level, while some are at the pathological level resulting from osteoporosis [ 29 , 30 ]. A SAMP6 mouse model of spontaneous senile osteoporosis was established in the present study and applied as experimental materials for investigating the regulatory effects of AR at different doses on osteoporosis administered by gavage.…”

Spontaneous senile osteoporosis severely threatens the health of the senior population which has emerged as a severe issue for society. A SAMP6 mouse model was utilized to estimate the impact of intragastrically administered Astragalus Membranaceus (AR) on spontaneous senile osteoporosis. Bone mineral density (BMD) and bone microstructure were measured using Micro-CT; contents of calcium and phosphorus were determined with the colorimetric method; and gene and protein expressions of fibroblast growth factor 23 (FGF23), Klotho, Vitamin D receptor (VDR), CYP27B1 and CYP24A1 were detected using qPCR, Western blot and ELISA assays, respectively. The findings indicated that AR could improve the femoral BMD and bone microstructure, elevate the contents of calcium and phosphorus, and increase the expression of Klotho, VDR, and CYP27B1 whereas decreasing the expression of FGF23 and CYP24A1 in SAMP6 mice in a dose independent manner. The present study has demonstrated that AR can promote osteogenesis and alleviate osteoporosis. It is also expected to provide a new insight for the treatment of spontaneous senile osteoporosis and to serve as a research basis for AR application.
