Abstract
BACKGROUND Osteoporosis is a bone metabolic disease that usually causes fracture. The improvement of the clinical diagnostic efficiency of osteoporosis is of great significance for the prevention of fracture. The predictive and diagnostic values of bone alkaline phosphatase (B-ALP) and 25-oxhydryl-vitamin D (25-OH-VD) for osteoporotic vertebral compression fractures (OVCFs) were evaluated. METHODS 110 OVCFs patients undergoing percutaneous vertebroplasty were included as subjects and their spinal computed tomography (CT) images were collected. After that, deep convolutional neural network model was employed for intelligent fracture recognition. Next, the patients were randomly enrolled into Ctrl group (65 cases receiving postoperative routine treatment) and VD2 group (65 cases injected with vitamin D2 into muscle after the surgery). In addition, 100 healthy people who participated in physical examination were included in Normal group. The differences in Oswestry dysfunction indexes (ODI), imaging parameters, B-ALP and 25-OH-VD expressions, and quality of life (QOL) scores of patients among the three groups were compared. The values of B-ALP and 25-OH-VD in predicting and diagnosing OVCFs and their correlation with bone density were analyzed. RESULTS It was demonstrated that computer intelligent medical image technique was more efficient in fracture CT recognition than artificial recognition. In contrast to those among patients in Normal group, B-ALP rose while 25-OH-VD declined among patients in Ctrl and VD2 groups (P < 0.05). Versus those among patients in Ctrl group, ODI, Cobb angle, and B-ALP reduced, while bone density, the height ratio of the injured vertebrae, 25-OH-VD, and QOL score increased among patients in VD2 group after the treatment (P < 0.05). The critical values, accuracy, and areas under the curve (AUC) of the diagnosis of OVCFs by B-ALP and 25-OH-VD amounted to 87.8 μg/L versus 30.3 nmol/L, 86.7% versus 83.3%, and 0.86 versus 0.82, respectively. B-ALP was apparently negatively correlated with bone density (r = - 0.602, P < 0.05), while 25-OH-VD was remarkably positively correlated with bone density (r = 0.576, P < 0.05). CONCLUSION To sum up, deep learning-based computer CT image intelligent detection technique could improve the diagnostic efficacy of fracture. B-ALP rose while 25-OH-VD declined among patients with OVCFs and OVCFs could be predicted and diagnosed based on B-ALP and 25-OH-VD. Postoperative intramuscular injection of VD2 could effectively improve the therapeutic effect on patients with OVCFs and QOL.

Abstract
Osteoporosis is a disease that reduces bone mass and microarchitecture, which makes bones fragile. Postmenopausal osteoporosis occurs due to estrogen deficiency. Raloxifene is a selective estrogen receptor modulator used to treat postmenopausal osteoporosis. However, it has a low bioavailability, which requires long-term, high-dose raloxifene administration to be effective and causes several side effects. Herein, raloxifene was encapsulated in human serum albumin (HSA)-based nanoparticles (Ral/HSA/PSS NPs) as an intravenous-injection pharmaceutical formulation to increase its bioavailability and reduce the treatment dosage and time. In vitro results indicated that raloxifene molecules were well distributed in HSA-based nanoparticles as an amorphous state, and the resulting raloxifene formulation was stabile during long-term storage duration. The Ral/HSA/PSS NPs were both biocompatible and hemocompatible with a decreased cytotoxicity of high-dose raloxifene. Moreover, the intravenous administration of the prepared Ral/HSA/PSS NPs to rats improved raloxifene bioavailability and improved its half-life in plasma. These raloxifene-loaded nanoparticles may be a potential nanomedicine candidate for treating postmenopausal osteoporosis with lower raloxifene dosages.

Nanomedicine and regenerative medicine approaches in osteoarthritis therapy. Aging Clin Exp Res 2022; 34:2305-2315. [PMID: 35867240 DOI: 10.1007/s40520-022-02199-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2022] [Accepted: 07/06/2022] [Indexed: 11/01/2022]
Abstract
Osteoarthritis (OA), the most common chronic joint disease, is a degenerative disease that affects 7% of the worldwide population, more than 500 million people all over the world. OA is the main factor of disability in elderly people which decreases the quality of life of patients. It is characterized by joint pain, low bone density, and deterioration of the joint structure. Despite ongoing novel advances in drug discovery and drug delivery, OA therapy is still a big challenge since there is no available effective treatment and the existing therapies mainly focus on pain and symptomatic management rather than improving and/or suppressing its progression. This review aims to summarize the currently available and novel emerging therapies for OA including regenerative medicine and nanotechnology-based materials and formulations at the clinical and experimental levels. Applications of regenerative medicine and novel technologies such as nanotechnology in OA treatments have opened a new window to support OA patients by offering treatments that could halt or delay OA progression satisfactorily or provide an effective cure in near future. Nanomedicine and regenerative medicine suggest novel alternatives in the regeneration of cartilage, repair of bone damage, and control of chronic pain in OA therapy.

Partoazar A, Goudarzi R. Phosphatidylserine liposomes containing curcumin inhibit bone loss in osteoporotic rats: A possible synergy through a common signaling pathway. J Food Biochem 2022; 46:e14120. [PMID: 35229314 DOI: 10.1111/jfbc.14120] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 01/28/2022] [Accepted: 01/28/2022] [Indexed: 11/27/2022]
Abstract
The present study aimed to investigate the effect of phosphatidylserine liposomes containing curcumin (PSLs-Cur) on the development of osteoporosis induced by glucocorticoids (GCs) in the rat model. PSL-Cur, phosphatidylserine (PSL), curcumin (Cur), and alendronate (AL) drugs as a positive control were administrated orally to evaluate the beneficial effects of 3-week treatments on osteoporotic rats. The biochemical and biomechanical properties of bone parameters as well as gene expression were evaluated in treated rats. Moreover, histomorphometric examinations were performed on the bone tissues of the animals. The results revealed that PSL-Cur oral administration caused a significant improvement in serum markers, mechanical strength, and OPG gene expression rather than PSL or Cur administration in osteoporotic rats. Also, PSL-Cur significantly increased the thickness and volume of cortical and trabecular bone mass in comparison with the untreated osteoporotic group. The results of this study indicated that PSL-Cur had a more inhibitory effect on bone loss induced by GCs compared to AL standard drug. Our findings suggested that PSL-loaded Cur may be an appropriate alternative therapy for glucocorticoid-induced osteoporosis. PRACTICAL APPLICATIONS: Osteoporosis is one of the most serious metabolic chronic diseases that causes fragile bone due to decreased mineral density and microarchitectural deterioration in humans. The osteoprotective effects of curcumin and phosphatidylserine, as a food spice and supplementary diet, respectively, have been shown, previously. However, the low bioavailability of curcumin (Cur) due to its poor absorption, rapid metabolism, and fast systemic elimination, limits its benefits. This deficit can be modified with phosphatidylserine liposome (PSL) formulation that facilitates the gastrointestinal delivery of Cur. Moreover, PSL is known as an osteoprotective agent that may make synergy effect with Cur against GC-induced osteoporosis. In this study, daily oral administration of phosphatidylserine liposomes containing curcumin (PSL-Cur) for 3 weeks, considerably improved biochemical, biomechanical, and gene expression of bone parameters in the treated animals subjected to osteoporosis. PSL-Cur can significantly increase the thickness and volume of cortical and trabecular bone mass as well as the mechanical bone strength in animals. Experimental findings proposed PSL-Cur consumption as a proper and safe supplementary medication in the controlling of bone loss in patients with a high risk of osteoporosis.

PART 2. Int J Nanomedicine 2021; 16:6049-6065.

Abstract
Purpose Healing of osteoporotic defects is challenging and requires innovative approaches to elicit molecular mechanisms promoting osteoblasts-osteoclasts coupling and bone homeostasis. Methods Cytocompatibility and biocompatibility of previously characterised nanocomposites, i.e Ca5(PO4)3OH/Fe3O4 (later called nHAp/IO) functionalised with microRNAs (nHAp/IO@miR-21/124) was tested. In vitro studies were performed using a direct co-culture system of MC3T3-E1 pre-osteoblast and 4B12 pre-osteoclasts. The analysis included determination of nanocomposite influence on cultures morphology (confocal imaging), viability and metabolic activity (Alamar Blue assay). Pro-osteogenic signals were identified at mRNA, miRNA and protein level with RT-qPCR, Western blotting and immunocytochemistry. Biocompatibility of biomaterials was tested using bilateral cranial defect performed on a senescence-accelerated mouse model, ie SAM/P6 and Balb/c. The effect of biomaterial on the process of bone healing was monitored using microcomputed tomography. Results The nanocomposites promoted survival and metabolism of bone cells, as well as enhanced functional differentiation of pre-osteoblasts MC3T3-E1 in co-cultures with pre-osteoclasts. Differentiation of MC3T3-E1 driven by nHAp/IO@miR-21/124 nanocomposite was manifested by improved extracellular matrix differentiation and up-regulation of pro-osteogenic transcripts, ie late osteogenesis markers. The nanocomposite triggered bone healing in a cranial defect model in SAM/P6 mice and was replaced by functional bone in Balb/c mice. Conclusion This study demonstrates that the novel nanocomposite nHAp/IO can serve as a platform for therapeutic miRNA delivery. Obtained nanocomposite elicit pro-osteogenic signals, decreasing osteoclasts differentiation, simultaneously improving osteoblasts metabolism and their transition toward pre-osteocytes and bone mineralisation. The proposed scaffold can be an effective interface for in situ regeneration of osteoporotic bone, especially in elderly patients.
