Abstract
To date, numerous delivery systems based on either organic or inorganic material have been developed to achieve efficient and sustained delivery of therapeutics. Hydrogels, which are three dimensional networks of crosslinked hydrophilic polymers, have a significant role in solving the clinical and pharmacological limitations of present systems because of their biocompatibility, ease of preparation and unique physical properties such as a tunable porous nature and affinity for biological fluids. Development of an in situ forming injectable hydrogel system has allowed excellent spatial and temporal control, unlike systemically administered therapeutics. Injectable hydrogel systems can offset difficulties with conventional hydrogel-based drug delivery systems in the clinic by forming a drug/gene delivery or cell-growing depot in the body with a single injection, thereby enabling patient compliance and comfort. Carbohydrate polymers are widely used for the synthesis of injectable in situ-forming hydrogels because of ready availability, presence of modifiable functional groups, biocompatibility and other physiochemical properties. In this review, we discuss different aspects of injectable hydrogels, such as bulk hydrogels/macrogels, microgels, and nanogels derived from natural polymers, and their importance in the delivery of therapeutics such as genes, drugs, cells or other biomolecules and how these revolutionary systems can complement existing therapeutic delivery systems.

Abstract
This work involved the construction of pH-responsive self-assembly systems from a pH-sensitive four-arm carboxylate acid (4EOCOOH) and either the cationic single chain surfactant dodecyl trimethyl ammonium bromide (DTAB) or the cationic gemini surfactant hexamethylene-1,6-bis(dodecyldimethylammonium bromide) (12-6-12). It was found that the constructed oligomeric-like structures from the mixtures of 4EOCOOH with DTAB or 12-6-12 greatly enhance the aggregation ability of the mixtures, thus improving the pH-responsivity. In particular, surfactant concentrations significantly affect the pH-responsivity at a fixed 4EOCOOH concentration. At higher surfactant concentrations, the pH-responsivity is suppressed, while at lower surfactant concentrations, the mixed aggregates gradually change from micelles to unstable large spherical aggregates or vesicles, and then to stable spherical aggregates, with decreasing pH. Moreover, the surfactant/4EOCOOH systems have different solubilization abilities for three hydrophobic drugs. For quercetin and baicalein, the systems support much better solubilization at lower pH values, while for indomethacin, the systems show better solubilization at higher pH values. In particular, compared with DTAB, 12-6-12 is more efficient in constructing pH-responsive systems, and the 12-6-12/4EOCOOH mixture shows better ability for solubilizing hydrophobic drugs. This work will be helpful in the design of high-efficiency, pH-responsive surfactant systems for solubilizing hydrophobic drugs by simply mixing pH-sensitive molecules with surfactants.

Abstract
Bioinspired materials have aroused great interest as their inherent biocompatible and structural characteristics have given rise to sustainable applications. In this work, we have reported the phase and morphology transformation of chitosan from crystalline nanofibrils into amorphous sheets for fabricating sustainable materials. Acetylation-induced aqueous dissolution of native chitosan nanofibrils affords water-soluble chitosan as a biopolymeric liquid. Water-soluble chitosan macromolecules self-aggregate into amorphous sheets on solidification, presenting an interesting way to inspire new structures of chitosan assemblies. Through control over gelation, lyophilization, and self-assembled confinement of water-soluble chitosan, we have fabricated novel chitosan materials including filaments, aerogels, microspheres, and plastics that are promising for sustainable use.

Abstract
The construction of multilayered films with tunable properties could offer new routes to produce biomaterials as a platform for 3D cell cultivation. In this study, multilayered films produced with five bilayers of chitosan and alginate (CHT/ALG) were built using water-soluble modified mesyl and tosyl–CHT via layer-by-layer (LbL) self-assembly. NMR results demonstrated the presences of mesyl (2.83 ppm) and tosyl groups (2.39, 7.37 and 7.70 ppm) in the chemical structure of modified chitosans. The buildup of multilayered films was monitored by quartz-crystal-microbalance (QCM-D) and film thickness was estimated using the Voigt-based viscoelastic model. QCM-D results demonstrated that CHT/ALG films constructed using mesyl or tosyl modifications (mCHT/ALG) were significantly thinner in comparison to the CHT/ALG films constructed with unmodified chitosan (p < 0.05). Adhesion analysis demonstrated that human adipose stem cells (hASCs) did not adhere to the mCHT/ALG multilayered films and formed aggregates with sizes between ca. 100–200 µm. In vitro studies on cell metabolic activity and live/dead staining suggested that mCHT/ALG multilayered films are nontoxic toward hACSs. Multilayered films produced via LbL assembly of ALG and off-the-shelf, water-soluble modified chitosans could be used as a scaffold for the 3D aggregates formation of hASCs in vitro.

Abstract
Xyloglucan (XG) is a multibranched polysaccharide consisting of a main chain β-1,4-glucan with xylose and galactose side chains. In this study, cholesterol-bearing XG (CHXG) was synthesized by the reaction of XG with cholesteryl N-(6-isocyanatohexyl) carbamate. The CHXG molecules self-assembled in water to form nanogels consisting of about 100 molecules of XG, and were characterized using light scattering and transmission electron microscopy. The number of cholesteryl groups per physical cross-linking site was estimated using a fluorescence quenching method. The resulting CHXG nanogels could be complexed with molecules of low molecular weight, such as iodine and paclitaxel, making the nanogels useful as drug carriers. The CHXG nanogels could also be specifically internalized by hepatocytes via the galactose receptors on their cell surface. CHXG self-assembled nanogels may be suitable as novel drug nanocarriers with galactose-specific targetability.

Abstract
Self-targetability is an emerging targeting strategy for polymer nanocarriers with facile preparation and high targeting efficiency. An acid-sensitive dextran-doxorubicin prodrug (Dex-g-DOX) has been synthesized and used as a self-targeted drug delivery system for the treatment of orthotopic hepatoma. The polysaccharide prodrug exhibits ultraselective accumulation in cancerous liver tissue, acid-sensitive DOX release within cells, and high antitumor efficacy in vitro and in vivo. Therefore, Dex-g-DOX demonstrates great potential for chemotherapy of orthotopic hepatoma.

Abstract
Objective
Over-expressions of HMGA2, vimentin and MMP-9 and downregulation of E-cadherin occur on colorectal cancer cells followed by a reduction in let-7 as a regulatory factor. In this study, we first used carboxymethyl dextran (CMD)–chitosan nanoparticles (ChNPs) platform to encapsulate HMGA2 siRNA and doxorubicin (DOX), and then, we evaluated the efficacy of the simultaneous delivery of siRNA/drug on viability and gene expression of HT-29 cell lines.

ChNPs characteristics were determined by a dynamic light scattering and zeta sizer. Morphology of loaded ChNPs was assessed by scanning electron microscopy, and Fourier transform infrared spectroscopy was used to confirm the conjugation of ChNP/siRNA/DOX/CMD. Cell viability and relative mRNA expression were evaluated by MTT assay and real-time PCR, respectively.
Key finding
The prepared ChNPs had high efficiency for siRNA and drug encapsulation (78% and 75%) and were stable against serum and heparin. ChNP/siRNA/DOX/CMD was more effective to induce tumour cell death and also could significantly reduce the expressions of HMGA2, vimentin as well as MMP-9 and increase E-cadherin expression.
Conclusion
In conclusion, our results revealed that dual delivery of a key gene siRNA and appropriate anticancer drug have great impact on the treatment of colorectal cancer.

Abstract
The present study was to evaluate the beneficial effect of polysaccharide isolated from Ganoderma atrum (PSG-1) on liver function in type 2 diabetic rats. Results showed that PSG-1 decreased the activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT), while increasing hepatic glycogen levels. PSG-1 also exerted strong antioxidant activities, together with upregulated mRNA expression of peroxisome proliferator-activated receptor-γ (PPAR-γ), glucose transporter-4 (GLUT4), phosphoinositide 3-kinase (PI3K), and phosphorylated-Akt (p-Akt) in the liver of diabetic rats. Moreover, the concentrations of short-chain fatty acids (SCFA) were significantly higher in the liver, serum, and faeces of diabetic rats after treating with PSG-1 for 4 weeks. These results suggest that the improvement of PSG-1 on liver function in type 2 diabetic rats may be due to its antioxidant effects, SCFA excretion in the colon from PSG-1, and regulation of hepatic glucose uptake by inducing GLUT4 translocation through PI3K/Akt signaling pathways.
