Abstract
Bone is a naturally mineralized tissue with a remarkable hierarchical structure, and the treatment of bone defects remains challenging. Microspheres with facile features of controllable size, diverse morphologies, and specific functions display amazing potentials for bone regeneration. Herein, inspired by natural biomineralization, a novel enzyme-catalyzed reaction is reported to prepare magnesium-based mineralized microspheres. First, silk fibroin methacryloyl (SilMA) microspheres are prepared using a combination of microfluidics and photo-crosslinking. Then, the alkaline phosphatase (ALP)-catalyzed hydrolysis of adenosine triphosphate (ATP) is successfully used to induce the formation of spherical magnesium phosphate (MgP) in the SilMA microspheres. These SilMA@MgP microspheres display uniform size, rough surface structure, good degradability, and sustained Mg2+ release properties. Moreover, the in vitro studies demonstrate the high bioactivities of SilMA@MgP microspehres in promoting the proliferation, migration, and osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs). Transcriptomic analysis shows that the osteoinductivity of SilMA@MgP microspheres may be related to the activation of the PI3K/Akt signaling pathway. Finally, the bone regeneration enhancement units (BREUs) are designed and constructed by inoculating BMSCs onto SilMA@MgP microspheres. In summary, this study demonstrates a new biomineralization strategy for designing biomimetic bone repair materials with defined structures and combination functions.

Biomedicines 2021; 9:biomedicines9050531.

Abstract
The aim of the study was to develop an orthopedic implant coating in the form of vancomycin-loaded collagen/hydroxyapatite layers (COLHA+V) that combine the ability to prevent bone infection with the ability to promote enhanced osseointegration. The ability to prevent bone infection was investigated employing a rat model that simulated the clinically relevant implant-related introduction of bacterial contamination to the bone during a surgical procedure using a clinical isolate of Staphylococcus epidermidis. The ability to enhance osseointegration was investigated employing a model of a minipig with terminated growth. Six weeks following implantation, the infected rat femurs treated with the implants without vancomycin (COLHA+S. epidermidis) exhibited the obvious destruction of cortical bone as evinced via a cortical bone porosity of up to 20% greater than that of the infected rat femurs treated with the implants containing vancomycin (COLHA+V+S. epidermidis) (3%) and the non-infected rat femurs (COLHA+V) (2%). The alteration of the bone structure of the infected COLHA+S. epidermidis group was further demonstrated by a 3% decrease in the average Ca/P molar ratio of the bone mineral. Finally, the determination of the concentration of vancomycin released into the blood stream indicated a negligible systemic load. Six months following implantation in the pigs, the quantified ratio of new bone indicated an improvement in osseointegration, with a two-fold bone ingrowth on the COLHA (47%) and COLHA+V (52%) compared to the control implants without a COLHA layer (27%). Therefore, it can be concluded that COLHA+V layers are able to significantly prevent the destruction of bone structure related to bacterial infection with a minimal systemic load and, simultaneously, enhance the rate of osseointegration.

Abstract
Biodegradable scaffolds are widely use in drug delivery and tissue engineering applications. The scaffolds can be modified to provide the necessary mechanical support for tissue formation and to deliver one or more drugs to stimulate tissue formation or for the treatment of a specific condition. In the current study, we developed biodegradable scaffolds that have the potential for dual drug delivery. The scaffolds consisted of simvastatin-containing prodrug, poly(simvastatin) entrapped in poly(β-amino ester) (PBAE) porogen particles and vancomycin encapsulated in poly(lactic-co-glycolic acid) (PLGA) microspheres, which were fused together around the PBAE porogens to create a slow-degrading matrix. Upon hydrolysis, poly(simvastatin) releases simvastatin acid, which has angiogenic and osteogenic properties, while the PLGA microspheres release vancomycin as an antibacterial agent. Degradation of PBAE porogens through hydrolysis of ester linkages led to the development of porosity in a controlled manner and led to water penetration that facilitated hydrolysis of PLGA. Higher porogen loading (~60% by weight) gave rise to ~70% interconnected porosity with pore spacing of ~180 μm. This open volume facilitated simvastatin acid release upon hydrolysis and entrapped vancomycin release via diffusion through and degradation of PLGA. During the study, ~162 μg of simvastatin acid and ~18 mg vancomycin were released from the highest porosity scaffolds. Bioactivity studies showed that released simvastatin acid stimulated preosteoblastic activity, indicating that scaffold fabrication did not damage the polymeric prodrug. Regarding mechanical properties, compressive modulus, failure strain, and failure stress decreased with increasing PBAE porogen content. These dual drug releasing scaffolds with controlled development of microarchitecture can be useful in bone tissue engineering applications.

Abstract
AbstarctInfections after bone reconstructive surgery are a real therapeutic and economic issue for the modern health care system. As the pathogen (most often Staphylococcus aureus) is able to develop a biofilm inside the bone, local delivery of antibiotics is of interest since high drug concentrations would be delivered directly at the target place. In this context, this study evaluated a porous hydroxyapatite implant as biocompatible bone substitute and vancomycin-delivery system to prevent post-operative infections. A simple method of impregnation with optimised conditions insured a high antibiotic loading (up to 2.3 ± 0.3 mg/m2), with a complete in vitro release obtained within 1-5 days. Additionally, the bacteriostatic and bactericidal effects of vancomycin were retained after loading on hydroxyapatite, as demonstrated after challenge with a Staphylococcus aureus strain. Regarding the biocompatibility, a wound healing assay of pre-osteoblastic MC3T3-E1 cells exposed to various concentrations of vancomycin revealed a dose-dependent reduction in cell migration for antibiotic concentrations higher than 1 mg/mL. Meanwhile, cells were able to proliferate normally on vancomycin-loaded scaffolds, although cell initial adhesion was seriously impaired for scaffolds loaded with 2.3 mg/m2 Loaded scaffolds could be stored up to three months at room temperature without any degradation of the antibiotic. Together, these results demonstrate the efficacy of these hydroxyapatite bone substitutes for local delivery of vancomycin in the context of bone infection.

Abstract
Infections of the musculoskeletal system present a serious problem with regard to the field of orthopedic and trauma medicine. The aim of the experiment described in this study was to develop a resorbable nanostructured composite layer with the controlled elution of antibiotics. The layer is composed of collagen, hydroxyapatite nanoparticles, and vancomycin hydrochloride (10 wt%). The stability of the collagen was enhanced by means of cross-linking. Four cross-linking agents were studied, namely an ethanol solution, a phosphate buffer solution of N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride/N-hydroxysuccinimide, genipin, and nordihydroguaiaretic acid. High performance liquid chromatography was used so as to characterize the in vitro release rates of the vancomycin and its crystalline degradation antibiotically inactive products over a 21-day period. The maximum concentration of the released active form of vancomycin (approximately 265 mg/L) exceeded the minimum inhibitory concentration up to an order of 17 times without triggering the burst releasing effect. At the end of the experiment, the minimum inhibitory concentration was exceeded by up to 6 times (approximately 100 mg/L). It was determined that the modification of collagen with hydroxyapatite nanoparticles does not negatively influence the sustainable release of vancomycin. The balance of vancomycin and its degradation products was observed after 14 days of incubation.

The controlled release of a glycopeptide drug, i.e. vancomycin, is attained by the intercalation of the polymer and drug macromolecules into silicate galleries. Fourier-transform infrared spectrometry reveals electrostatic interactions between the charged structure of clay and the amine and hydroxyl groups of chitosan and vancomycin, leading to a complex positively-charged system with high electrophoretic mobility. By applying electric field the charged particles are deposited on the surface of titanium foils and uniform chitosan films containing 25-55 wt% Laponite and 937-1655 µg/cm(2) vancomycin are obtained. Nanocomposite films exhibit improved cell attachment with higher cell viability. Alkaline phosphatase assay reveals enhanced cell proliferation due the gradual dissolution of Laponite particles into the culture medium. In-vitro drug-release studies show lower release rate through a longer period for the nanocomposite compared to pristine chitosan.

Abstract
Tumor necrosis factor-α (TNF-α) plays an important role in the abnormal metabolism of osteoblasts (OBs), which leads to subchondral bone (SB) alterations in osteoarthritis. In the present study, Tougu Xiaotong capsule (TXC), a traditional Chinese medicine, was used to treat TNF-α-injured OB-like cells. The cellular viability, mortality and ultramicroscopic morphology were evaluated. Thereafter, the activity of alkaline phosphatase (ALP), secretion of osteocalcin (OCN) and mineralization of nodules were analyzed. The results showed that TXC treatment significantly promoted cell proliferation, reduced cellular mortality and improved cellular ultrastructure, particularly that of the endoplasmic reticulum and nucleus. These data indicate that TXC is able to promote cell growth, as well as prevent inflammation in OB-like cells. Furthermore, the activity of ALP, secretion of OCN and mineralization of nodules were accelerated, and the calcium content of the TNF-α-injured OB-like cells was promoted by TXC treatment. These results indicate that TXC protected the OB-like cells from TNF-α-induced injuries. This may be a potential mechanism through which TXC regulates SB remodeling in the clinical treatment of osteoarthritis.

Abstract
Orthopaedic implant-associated infections are one of the most serious complications in orthopaedic surgery and a major cause of implant failure. In the present work, drug-eluting coatings based on chitosan containing various amounts of vancomycin were prepared by a cathodic electrophoretic deposition process on titanium foils. A three-step release mechanism of the antibiotic from the films in a phosphate-buffered saline solution was noticed. At the early stage, physical encapsulation of the drug in the hydrogel network controlled the release rate. At the late stage, however, in vitro degradation/deattachment of chitosan was responsible for the controlled release. Cytotoxicity evaluation of the drug-eluting coatings via culturing in human osteosarcoma cells (MG-63 osteoblast-like cell line) showed no adverse effect on the biocompatibility. Antibacterial tests against Gram-positive Staphylococcus aureus also demonstrated that the infection risk of titanium foils was significantly reduced due to the antibiotic release. Additionally, in vitro electrochemical corrosion studies by polarization technique revealed that the corrosion current density was significantly lower for the titanium foils with drug-eluting coatings compared to that of uncoated titanium.

Abstract
The multifunctional strontium (Sr)-substituted hydroxyapatite microsphere was prepared via hydrothermal method, in which the luminescent and controlled drug release functions can be realized. The structure and morphology of the as-prepared microspheres were studied by using XRD, FTIR, SEM, TEM, HR-TEM, BET method. The optical properties was investigated by using photoluminescence (PL) and XPS measurement. Then, the as-prepared multifunctional microspheres were performed as a drug delivery carrier using vancomycin as a model drug. The experimental results show that the composition, morphology, luminescent properties and drug storage/release behaviour were obviously influenced by the amount of Sr. The microspheres with Sr(2+)/(Ca(2+) + Sr(2+)) = 0.3 of Sr substitution showed the maximum specific surface area, best pore structure and strongest PL intensity. All the samples presented remarkable sustained drug release kinetics. In addition, the PL intensity of SrHA in the drug delivery system increased with the cumulative release time (amount) of vancomycin, which would make the drug release might be possibly tracked by the change of the luminescent intensity. Our study indicated a potential prospect that the fabricated multifunctional SrHA mesoporous microspheres might be applied in the field of bone regeneration and drug delivery.
