Enhanced degradation of enoxacin using ferrihydrite-catalyzed heterogeneous photo-Fenton process.

The ferrihydrite-catalyzed heterogeneous photo-Fenton reaction shows great potential for environmental remediation of fluoroquinolone (FQs) antibiotics. The degradation of enoxacin, a model of FQ antibiotics, was studied by a batch experiment and theoretical calculation. The results revealed that the degradation efficiency of enoxacin reached 89.

A composite hydrogel with antibacterial and promoted cell proliferation dual properties for healing of infected wounds.

Wound infection remains a major challenge for health professionals, because it delays wound healing and increases the overall cost and morbidity. Therefore, the development of new biomaterials with new antibacterial properties and healing effects remains a dire clinical need. To solve this problem, we developed silver nanoparticles embedded in γ-cyclodextrin metal-organic frameworks (Ag@MOF) and platelet-rich plasma (PRP)-loaded hydrogel systems based on methacrylated silk fibroin (SFMA) and methacrylate hyaluronic acid (HAMA) as Ag ion and growth factor delivery vehicles for inhibiting the growth of drug-resistant bacteria and promoting wound healing.

Human fetal mesenchymal stem cells secretome promotes scarless diabetic wound healing through heat-shock protein family.

The high mortality rate of patients with diabetic foot ulcers is urging the appearance of an effective biomedical drug. Senescence is one of the major reasons of aging-induced decline in the diabetic wound. Our previous studies have demonstrated the anti-senescence effect of secretomes derived from human fetal mesenchymal stem cells (hfMSC).

[Comparison of functional recovery of distal radius fracture by suture of pronator muscle through modified Henry approach].

Objective: To investigate the effect of suture of pronator muscle on forearm function after modified Henry approach for distal radius fractures.

Methods: from January 2018 to December 2020, 220 patients with distal radius fractures were treated with open reduction and locking plate internal fixation through the modified Henry approach. They were divided into two groups according to different suture methods.

Antibiotic-loaded chitosan-gelatin scaffolds for infected seawater immersion wound healing.

Skin damaged during sea battles is vulnerable to seawater immersion and bacterial infection. Scaffolds with effective biological function are highly desired for treatment of naval combat wound injuries. Herein, we prepared composite scaffolds of CS/GEL/GMs-CIP.
