Abstract
Non-healing chronic diabetic wound treatment remains an unsolved healthcare challenge and still threatens patients' lives. Recently, hydrogel dressings based on natural biomaterials have been widely investigated to accelerate the healing of diabetic wounds. In this study, we introduce a bioactive hydrogel based on fish gelatin (FG) as a candidate for diabetic wound treatments, which is a recently emerged substitute for mammalian derived gelatin. The composite hydrogel simply fabricated with FG and oxidized hyaluronate (OHy) through Schiff base reaction could successfully accelerate wound healing due to their adequate mechanical stability and self-healing ability. In vitro studies showed that the fabricated hydrogels exhibited cytocompatibility and could reduce pro-inflammatory cytokine expression such as NO, IL-1β, TNF-α, and PGE2 in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. In addition, the production of reactive oxygen species (ROS), a key marker of free radicals producing oxidative stress, was also reduced by fabricated hydrogels. Furthermore, in vivo experiments demonstrated that the hydrogel could promote wound closure, re-epithelialization, collagen deposition, and protein expression of CD31, CD206, and Arg1 in diabetic mice models. Our study highlights the advanced potential of FG as a promising alternative material and indicates that FOHI can be successfully used for diabetic wound healing applications.

Abstract
A 68-year-old male patient with chronic hypertension, diabetes mellitus and chronic renal failure was diagnosed with acute calculous cholecystitis. A percutaneous cholecystostomy using a transperitoneal approach was performed after two failed attempts with a right-sided transhepatic approach. Subsequent hepatic embolisation was performed for the treatment of haemoperitoneum due to hepatic injury after the percutaneous cholecystostomy. The presence of a left-sided gallbladder was confirmed by laparoscopic cholecystectomy after 1 week. Prior identification of this anomaly would have prevented hepatic injury through the use of a cautious procedure against mobility or careful selection of the approach routes. In conclusion, the transperitoneal approach can be easier or more preferable to perform for a percutaneous cholecystostomy of a left-sided gallbladder.
