Facile fabrication of chitosan/hyaluronic acid hydrogel-based wound closure material Co-loaded with gold nanoparticles and fibroblast growth factor to improve anti-microbial and healing efficiency in diabetic wound healing and nursing care.

Generally, diabetic wounds heal very slowly and inefficiently with an increasing risk of infections. Recent nanotechnology and biomaterial advances elaborate developed multi-functional hydrogels and nanoparticles offer promising solutions to accelerate wound healing for diabetic patients. This research work demonstrates to use of solvent diffusion method to develop hydrogel nanocomposites composed of chitosan (CS), hyaluronic acid (HA), gold (Au), and fibroblast growth factors (FGF).

Ectopic eruption of the first permanent molar: Predictive factors for irreversible outcome.

Introduction: The present study aimed to analyze possible factors involved in irreversible (IRR) ectopic eruption (EE) of the first permanent molar and explore potential predictors for the IRR outcome.

Methods: Children aged 4-11 years, with at least 1 EE and who took their first panoramic radiograph before the age of 8 years, were selected in this study. The subjects were assigned to the self-correcting (SC) and IRR groups.

[Effects of dynamic nutrition support on energy metabolism, immune function and stress response after oral and maxillofacial tumor surgery].

Purpose: To observe the effect of dynamic nutrition support on postoperative energy metabolism, immune function and stress response in patients with oral and maxillofacial tumors.

Methods: Fifty-six patients with oral and maxillofacial tumor surgery were randomly divided into experimental group and control group (28 in each group). Patients in the experimental group received dynamic enteral and parenteral nutrition support according to the stress period after surgery, ω-3 fish oil fat milk injection and glutamine were added in the nutrition support program.

Characterization of the clustered regularly interspaced short palindromic repeats sites in Streptococcus mutans isolated from early childhood caries patients.

Objective: The aim of this study was to analyze the characteristics of the clustered regularly interspaced short palindromic repeats (CRISPR) sites in 45 clinical Streptococcus mutans strains and their relationship to the clinical manifestations of early childhood caries (ECC).

Methods: Forty-five S. mutans strains were isolated from the plaque samples taken from sixty-three children.

[Expression and distribution of SDF-1 in the soft tissue healing of tooth extraction].

Purpose: To observe the expression and distribution of stromal cell derived factor -l (SDF-1) in the soft tissues after tooth extraction, in order to provide new ideas to promote wound healing of tooth extraction.

Methods: Thirty male Wistar rats were randomly divided into 10 groups. After extracting the first molar of left mandibular respectively, immunohistochemistry and RT-PCR technique were used to evaluate the distribution and expression of SDF-1 1, 2, 4, 7 and 10 days after extraction.
