BACKGROUND: Preliminary study has prepared the silk fibroin/chitosan/nano-hydroxyapatite composite bioscaffold and the recombinant human bone morphogenetic protein 2/polylactic acid sustained release system. OBJECTIVE: To observe the effect of radial bone defect repairing in dogs with composite bioscaffold loaded with recombinant human bone morphogenetic protein 2/poly(lactic acid) sustained-release microspheres. METHODS: Silk fibroin/chitosan/nano-hydroxyphosphorous bioscaffolds were prepared by vacuum freeze-drying and chemical crosslinking. Recombinant human bone morphogenetic protein 2/poly(lactic acid) sustained-release microspheres were prepared by compound emulsion volatilization, and then prepared the three-dimensional bioscaffold. Eight adult dogs (provided by the Experimental Animal Center of Zunyi Medical University) were used to make a critical bone defect model of the radius (3 cm in the middle radius). Four bone defects were implanted with the three-dimensional bioscaffold with sustained release microspheres and autologous cancellous bones (experimental group 1). The other four only implanted with autologous cancellous bone (control group 1). Another eight adult dogs were used to make a superficial bone defect model of the radius (5 cm in the middle radius). Four bone defects were implanted with the three-dimensional biological scaffold with sustained release microspheres and autologous cancellous bone (experimental group 2). The other four were implanted only with autologous cancellous bone (control group 2). X-ray examination was performed at postoperative 4, 8, and 12 weeks. At postoperative 12 weeks, the radius of the defect area was removed for histopathological observation. The study was approved by the Ethics Committee of Zunyi Medical University, approval number: (2016)2-071. RESULTS AND CONCLUSION: (1)X-ray: at postoperative 12 weeks, the medullary cavity in the experimental group 1 was recanalized and the cortical bone was formed. The defect in the control group 1 was basically completely connected, but the medullary cavity recanalization and cortical bone shaping were incomplete. In the experimental group 2, the medullary cavity was basically recanalized, the cortical bone shaping and bone ingrowth were basically completed. The control group 2 appeared no bone connection, no cortical bone shaping. (2) Histological observation: in the experimental group 1, the bone defect was connected completely, and the cortical bone formation and complete medullary cavity recanalization were observed. In the control group 1, bone tissue was formed, and a large amount of fibrous tissues were observed, no cortical bone was formed, and the medullary cavity was not recanalized. In experimental group 2, the cortical bone formation and the completion of the medullary cavity were recanalized in the bone defect. The control group 2 showed a small amount of bones, no cortical bone formation and recanalization of the medullary cavity. The experimental group 1 has better bone repair effect than the experimental group 2. (3) These results imply that the three-dimensional bioscaffolds loaded with recombinant human bone morphogenetic protein 2/poly (lactic acid) sustained-release microspheres can effectively repair the critical and supercritical bone defects of canine tibia to some extent.

BACKGROUND: In recent years, myocardial tissue engineering has developed rapidly. By using exogenous biomaterials to simulate extracellular matrix, damaged myocardial cells can be effectively repaired or reconstructed, which has great potential value in the treatment of ischemic heart diseases such as myocardial infarction. OBJECTIVE: To review the research progress of myocardial scaffolds in the treatment of myocardial infarction. METHODS: NCBI and WanFang databases were retrieved for relevant articles published from 2008 to 2018, with the key words of “myocardial scaffold materials, myocardial infarction” in English and Chinese, respectively. RESULTS AND CONCLUSION: At present, the commonly used myocardial scaffolds are mainly natural biomaterials (including collagen/ Matrigel, fibrin, chitosan, hyaluronic acid, and algae hydrochloric acid), synthetic materials (polyester synthetic materials and nanomaterials) and composite scaffolds. Due to the complexity of cardiac environment and heart function, the selection of scaffold materials should fully take account of biocompatibility, immunogenicity, conductivity, degradation rate and susceptibility to ischemia and hypoxia. Although many scaffold designs have begun to meet many requirements, there are still many kinds of stent materials for clinical application. It is believed that with the further development of researchers and application tools, people can expect to create myocardial scaffolds close to the physiological function of the original tissue, so that the heart function can be better restored.

OBJECTIVE: To explore the mechanical properties, physical characteristics, chemical composition and antibiotic sustained-release ability of three-dimensional silk fibroin/chitosan/nano-hydroxyapatite scaffold loaded with levofloxacin. METHODS: Levofloxacin/chitosan (3:1) microspheres were constructed by emulsion settlement filter method. 5, 7.5 and 10 g of microspheres were added into 2% of silk fibroin/chitosan/nano-hydroxyapatite mixed solution through freeze drying and chemical cross-linking to obtain the scaffolds loaded with antibiotics. The scaffolds loaded with antibiotics underwent scanning electron microscope observation, and chemical composition analysis. The sustained release, mechanical properties, porosity, water absorption expansion rate and hot water soluble loss rate were detected. RESULTS AND CONCLUSION: (1) Scanning electron microscope observed that there were drug microspheres at the inner wall of the scaffold, and the voidage was decreased with mass of microspheres increasing. (2) Energy spectrum analysis showed that the three kinds of scaffolds were rich in calcium and phosphonium ions. (3) The three kinds of scaffolds showed the same releasing trend, which presented with sudden-release effect at the former 3 days (release > 50%), and then tended to be stable. The release rate was the slowest in the scaffold loaded with 10 g of microscopes, and the rapidest in the scaffold loaded with 5 g of microscopes. (4) With the mass of microspheres increasing, there was an increase in the compressive and tension abilities and hot water soluble loss rate, and a decrease in the porosity, mean pore size and water absorption expansion rate. (5) These results indicate that the three-dimensional tissue-engineered scaffold loaded with levofloxacin is constructed successfully by freeze drying and chemical cross-linking method, which holds good sustained-release effect and compressive ability, water absorption expansion rate and hot water soluble loss rate.

BACKGROUND: Chitosan has become a research hotspot of cartilage repair materials because of a wide range of biological sources, simple preparation processes and excellent biocompatibility. OBJECTIVE: To review the characteristics of chitosan hydrogels and their application in cartilage repair. METHODS: PubMed and CNKI databases were searched by computer with the keywords of “chitosan; chitosan hydrogel; cartilage repair; tissue engineering” in English and Chinese, respectively. The time range was from January 2000 to March 2018. After initial screening, the retained articles were further analyzed, concluded and summarized. RESULTS AND CONCLUSION: Chitosan has good biocompatibility, low toxicity, low immunogenicity, and can load multiple growth factors and seed cells with different physical or chemical improvements. Encouraging progress in tissue engineering cartilage repair has been achieved. With the development of technology and the understanding of cartilage and subchondral bone structure, the application range of chitosan biomimetic hydrogel has been broadened. However, the molecular mechanism and degradation process of chitosan in vivo still have a lot of controversies, and further research and exploration are needed. [ABSTRACT FROM AUTHOR]

BACKGROUND: Preliminary studies have confirmed that vancomycin sustained-release microspheres exert satisfactory therapeutic effect on chronic osteomyelitis in rabbits. Nano-hydroxyapatite/chitosan (nHA/CS) has good biocompatibility, degradability and osteogenic induction. Autologous red bone marrow can be used as a seed cell source combined with nHA/CS scaffold to repair rabbit tibia bone defects. Therefore, the combined effects of the three materials in the repair of rabbit chronic osteomyelitis bone defects need a further investigation. OBJECTIVE: To explore the efficacy and feasibility of nHA/CS scaffold carrying vancomycin/polyactic-co-glycolic acid (PLGA) sustained-release microspheres combined with autologous red bone marrow in the repair of chronic osteomyelitis bone defects in rabbits. METHODS: Vancomycin/PLGA sustained-release microspheres were prepared by water oil and water emulsion method. The nHA/CS scaffolds carrying vancomycin/PLGA sustained-release microspheres were prepared by vacuum freeze drying, and mechanical properties and vancomycin release of the scaffold were determined. Twenty 5-month-old New Zealand white rabbits provided by Laboratory Animal Centre of Daping Hospital of Third Military Medical University were selected for establishing the chronic osteomyelitis bone defect model by intramedullary infection of Staphylococcus aureus into the left tibia. The model rabbits were randomly divided into four groups: group A was only given only for debridement treatment; in group B, the nHA/CS scaffold was implanted after debridement; in group C, nHA/CS scaffolds carrying vancomycin/PLGA sustained-release microspheres were implanted after debridement; in group D, nHA/CS scaffolds carrying vancomycin/PLGA microspheres and autologous red bone marrow were implanted after debridement. At 3 months after implantation, the repair effect was observed by X-ray and hematoxylin-eosin staining. RESULTS AND CONCLUSION: The nHA/CS scaffolds carrying vancomycin/PLGA sustained-release microspheres held good biomechanical properties and drug sustained release. At 3 months after implantation, X-ray revealed that the defect region in the groups A and B had no obvious improvement, and there were still bone destruction and periosteal reaction. The group C showed the formation of the new bone, the defect area was slightly blurred, but the defect still existed. In the group D, new bone formed, the defect area became blurred, the density was slightly high, and the periosteum reaction disappeared. Hematoxylin-eosin staining showed the bone trabecular disorder and more damage in the groups A and B. The bone trabecula was neatly arranged and less damaged in the groups C and D, and especially the group D had thickened bone trabecula arranged regularly. These results indicate that nHA/CS scaffolds carrying vancomycin/PLGA sustained-release microspheres combined with autologous red bone marrow exhibit good outcomes in repairing the bone defect due to chronic osteomyelitis in rabbits.

BACKGROUND: With the development of stem cell therapy and tissue engineering, adipose-derived mesenchymal stem cells combined with biocompatible scaffolds have been introduced to constructing liver tissue engineering micro-units as a new strategy for the treatment of liver diseases. OBJECTIVE: To investigate the repairing ability of adipose-derived mesenchymal stem cells combined with porous chitosan microspheres on acute liver injury. METHODS: Adipose-derived mesenchymal stem cells from neonatal Sprague-Dawley rats and porous chitosan microspheres were co-cultured in vitro to observe the proliferation of adipose-derived mesenchymal stem cells on the microspheres on the 1st, 3rd and 5th days. Thirty-six Sprague-Dawley rats (provided by Beijing Vital River Laboratory Animal Technology Co., Ltd. in China) were randomly divided into three groups (n=12 per group): control group was intraperitoneally injected with normal saline; acute liver injury group was intraperitoneally administered with 10% carbon tetrachloride-olive oil; and cell-microsphere group was intraperitoneally given 10% carbon tetrachloride-olive oil and then adipose-derived mesenchymal stem cells-porous chitosan microspheres were implanted into the liver surface on the 1st day after injection. Gross, serological and histological evaluations were performed on the 1st, 2nd, 3rd and 7th days. RESULTS AND CONCLUSION: Adipose-derived mesenchymal stem cells-porous chitosan microspheres were stained with live/dead staining on the 1st, 3rd and 5th days. The cells grew normally on the microspheres as the number of dead cells was much less than that of living cells, and the cells proliferated continuously over time. The gross score, liver function score and histological score of the cell-microsphere group were higher than those of the acute liver injury group on the 1st, 2nd, 3rd and 7th days. There was no significant difference between the cell-microsphere group and control group since the 3rd day. All these experimental findings indicate that adipose-derived mesenchymal stem cells-porous chitosan microspheres implanted onto the liver surface can accelerate the repair of liver injury.

BACKGROUND: The transfection of angiogenic genes into cells by slow-release technology is the key to adequate vascularization of tissue engineered bone, and it is most important to select the safe and effective gene carrier. OBJECTIVE: To prepare and characterize superparamagnetic iron oxide chitosan nanoparticles (SPIOCN) and superparamagnetic chitosan plasmid gelatin microspheres (SPCPGM). METHODS: SPIOCN was prepared by dehydration condensation reaction, and the molecular structure, morphology and particles size, saturation magnetization, ζ potential and DNA binding ability were respectively characterized. SPIOCN solution was incubated with MG-63 cells for 24 hours, and cell phagocytosis of SPIOCN was observed by transmission electron microscope. SPCPGM and non-magnetic chitosan gelatin microspheres were prepared, which were filled in the porous cage, and the plasmid release of SPCPGM intended for implantation in the porous cage in the presence of and absence of oscillating magnetic fields was carried out in 0.01 mol/L phosphate buffer at 37 oC (pH=7.4). MG-63 cells and human umbilical vein endothelial cells were selected as target cells for transfection, which were divided into four groups and respectively intervened by PolyMag200 (commercial magnetic transfection reagent)/Pdna+the static magnetic field, SPIOCN/pDNA+the static magnetic field, SPIOCN/pDNA and naked pDNA. The transfection efficiency was then detected by inverted fluorescence microscope and flow cytometry after 24 hours. Human umbilical vein endothelial cells were cultured in four groups: PolyMag200/pDNA+the static magnetic field group, SPIOCN/pDNA+the magnetic field group, SPIOCN/pDNA group and naked pDNA group (control group). Cell viability was detected after 24, 48 and 72 hours of culture. RESULTS AND CONCLUSION: (1) The average particle size of SPIOCN was (187±24) nm, the saturation magnetization was (20.3±4.5) emu/g and the zeta potential was (9.5±2.4) mV, indicating that SPIOCN endows the combination ability with plasmid DNA transfected into MG-63 cells and human umbilical vein endothelial cells. (2) SPIOCN was attached to the cell membrane and entered into the cells through intracellular endocytosis pathway. SPIOCN swallowed as endosomes were dispersed in the cytoplasm. (3) The releasing plasmid amount of SPCPGM implanted in the porous cage in the presence of magnetic field was significantly higher than that of non-magnetic chitosan gelatin microspheres implanted in the porosity cage (P < 0.05). (4) The transfection efficiency of PolyMag200/pDNA+the static magnetic field group was higher than that of the other three groups (P < 0.05), and the transfection efficiency of SPIOCN/pDNA+the static magnetic field group was higher than that of SPIOCN/pDNA group and naked pDNA group (P < 0.05). (5) Compared with the naked pDNA group, the cell survival rate of SPIOCN/pDNA+the static magnetic field group and PolyMag200/pDNA+the static magnetic field group decreased at different time points (P < 0.05), while the cell survival rate of SPIOCN/pDNA group showed no significant changes. The cell survival rate of SPIOCN/ pDNA+ static magnetic field group at different time points was higher than that of PolyMag200/pDNA+the static magnetic field group (P < 0.05). To conclude, SPIOCN has the characteristics of small particle size, good dispersibility, low toxicity, superparamagnetism and combined protection of DNA transfected cells. The oscillating magnetic field integrated with SPCPGM is an ideal system of slow-release gene carriers. [ABSTRACT FROM AUTHOR]

A series of modified mesh were prepared by dipping coated method with chitosan and nano-titanium as raw material and stainless steel mesh as substrate. The influence of concentration of chitosan, concentration of nano-titanium and different dipping orders on hydrophilicity/oleophobicity underwater of modified meshes were studied. These modified stainless steel meshes were characterized by scanning electron microscope(SEM) and contact angle tester. And the separation efficiency was tested. The results demonstrated that when the outside is nano-titanium and the concentration of nano-titanium is 2wt%, the underwater oil contact angle is as high as135o, the separation efficiency is 99.02%; when the outside is chitosan and the concentration of chitosan is 0.36wt%, the underwater oil contact angle is as high as133o, the separation efficiency is 99.43%. When chitosan and nano-titanium blends, the optimizing blends condition is 0.09wt% chitosan and 2wt% nano-titanium. In this condition, the underwater oil contact angle is as high as138°, the separation efficiency is 99.13%. The modified stainless steel meshes prepared have an excellent hydrophilicity/oleophobicity underwater property for oil-water separation. [ABSTRACT FROM AUTHOR]

Nanogels are nano-scaled three-dimensional networks, generally with good hydrophilicity and structural stability. As a natural macromolecular polysaccharide, chitosan has a great number of advantages such as non-toxicity and good biodegradability which has aroused wide attention. In this paper, with chitosan (CS) as the main building block, the free radical graft copolymerization is initiated at the hydroxyl carbon of chitosan and the nano-scaled aggregates are induced by the self-assembly of the hydrophobic poly(methyl acrylate) (PMA) graft chains. By introducing the redox-responsive cross-linker diallyl disulfide (DADS), the structure is locked and the tumor sensitive chitosan-poly(methyl acrylate) (CS-PMA) nanogels are obtained at high efficiency. This strategy is named as graft copolymerization induced self-assembly (GPISA). The size, morphology and structure of the nanogels are characterized by transmission electron microscopy (TEM), dynamic laser light scattering (DLS), FT-IR. The size of the nanogels can be controlled via adjusting synthetic parameters. Moreover, the nanogels can be modified with near infrared (NIR) fluorescence molecules-Cy5.5-NHS ester and magnetic resonance imaging (MRI) enhancement molecules-Gd-DTPA, leading to fluorescent/MRI dual-functional nanogels. Characterization results of MRI and fluorescence imaging demonstrate that the nanogels show great cell-labelling capability. The cell toxicity study by MTT assay confirm the low cytotoxicity of the nanogels to lymphatic endothelial cells (LECs) and breast cancer cells (MCF-7). All these results indicate that the bio-functional nanogels have great potential as NIR/MRI probe for the diagnosis and therapy of tumor. [ABSTRACT FROM AUTHOR]
