Clinical application of common inflammatory and nutritional indicators before treatment in prognosis evaluation of non-small cell lung cancer: a retrospective real-world study.

Objective: To evaluate the prognostic value of common clinical inflammatory and nutritional indicators before treatment in patients with non-small cell lung cancer in the real world.

Method: A total of 5,239 patients with pathologically confirmed non-small cell lung cancer from 2011 to 2018 in the Affiliated Cancer Hospital of Xinjiang Medical University were selected. Their inflammatory and nutritional indicators (RDW, PDW, NLR, LMR, NMR, PLR, SII, PNI, TP, ALB, CYRFA21-1, CEA, CA125, NSE, α1-globulin, α2-globulin, β1-globulin, β2-globulin, and γ-globulin) before treatment were collected.

Bifunctional scaffolds of hydroxyapatite/poly(dopamine)/carboxymethyl chitosan with osteogenesis and anti-osteosarcoma effect.

The bifunctional tissue engineering scaffold with anti-tumor and bone repair properties is promising for the therapy of bone tumor where large bone defects often occur. In this study, hydroxyapatite (HA), poly(dopamine) (PDA), and carboxymethyl chitosan (CMCS) composite scaffolds were prepared by the 3D-printing technology. PDA significantly improved the rheological properties of the slurry for molding, mechanical properties, surface relative potential, and water absorption of composite scaffolds.

Biodegradable 3D printed HA/CMCS/PDA scaffold for repairing lacunar bone defect.

Three-dimensional (3D) printing technology has attracted considerable focus for preparing porous bone repair scaffolds to promote bone regeneration. Inspired by organic-inorganic components and the porous structure of natural bone, novel porous degradable scaffolds have been printed using hydroxyapatite (HA), carboxymethyl chitosan (CMCS), and polydopamine (PDA). The well-designed HA/CMCS/PDA scaffolds exhibited a porous structure with 60.

Tailorable hierarchical structures of biomimetic hydroxyapatite micro/nano particles promoting endocytosis and osteogenic differentiation of stem cells.

Hydroxyapatite (HA) micro/nano particles show great promise as artificial bone and dental substitutes, or drug carrier systems. However, the precise regulation of hydroxyapatite micro/nano particles with controllable physicochemical properties (such as hierarchical structure, particle size, potential and crystallinity) is still a challenge. Furthermore, the effects of different hierarchical structures on biological responses have been rarely reported.

Biomimetic mineralization of carboxymethyl chitosan nanofibers with improved osteogenic activity in vitro and in vivo.

Inspired by the natural extracellular matrix, the organic-inorganic composite nanofibers are promising scaffolds for bone tissue engineering. Chitosan-based nanofibers are widely used as bone tissue engineering scaffolds with good biocompatibility but pungent solvents are frequently used for its processing. Carboxymethyl chitosan (CMCS), a water-soluble derivative of chitosan, has better biodegradability and bioactivity which allows CMCS to chelate Ca and induce the deposition of apatite.
