Colorectal peritoneal carcinomatosis (CRPC) is an advanced stage of colorectal cancer (CRC), which significantly decreases patient survival and quality of life. Here, the naturally occurring polysaccharide hyaluronic acid (HA) was used to prepare an injectable hydrogel and simultaneously deliver 5-fluorouracil (5-FU), cisplatin (DDP) and paclitaxel (PTX) microspheres for intraperitoneal CRPC chemotherapy. The drug-loaded HA hydrogel released the drugs in a sustained manner, and showed low toxicity both in vitro and in a mouse model of CRPC. Furthermore, direct injection of the drug-loaded HA hydrogel in the abdominal cavity of tumor-bearing mice significantly decreased tumor growth and liver/lung metastasis, along with decreasing the volume of ascites and inhibiting local intestinal infiltration of the tumor cells. Therefore, this novel multi-drug hydrogel delivery system may effectively clear CRPC tumors without any adverse effects when used in intraperitoneal chemotherapy.

Background: Hyaluronic acid (HA) fillers are commonly used in esthetic medicine for facial contouring and rejuvenation. However, complications such as overcorrection, vascular occlusion, and irregular filler distribution necessitate the use of hyaluronidase to dissolve the fillers. This study aimed to evaluate the efficacy of hyaluronidase in degrading different types of HA fillers and provide clinical guidelines for its use based on filler type, dosage, and application techniques.

Uncontrollable non-compressible hemorrhage and traumatic infection have been major causes of mortality and disability in both civilian and military populations. A dressing designed for point-of-care control of non-compressible hemorrhage and prevention of traumatic infections represents an urgent medical need. Here, a novel self-gelling sponge OHN@ε-pL is developed, integrating N-succinimidyl ester oxidized hyaluronic acid (OHN) and ε-poly-L-lysine (ε-pL).

The increase of the incidence of autoimmune diseases and, at the same time, a significant surge in the number of regenerative/anti-aging medicine treatments carried out, raises the need to systematise the current knowledge on the safety of the use of hyaluronic acid fillers in patients with autoimmune diseases and to frame management guidelines for aesthetic doctors. One of the most prevalent autoimmune diseases is chronic lymphocytic thyroiditis, so-called Hashimoto's disease, which affects one in every 5-10 women who visit a regenerative medicine doctor. Women in the perimenopausal and menopausal period, aged 40-54 years, were the single largest target group for aesthetic treatments.

Hyaluronic acid (HA) is a popular surface modifier in targeted cancer delivery due to its receptor-binding abilities. However, HA alone faces limitations in lipid solubility, biocompatibility, and cell internalization, making it less effective as a standalone delivery system. This comprehensive study aimed to explore a dynamic landscape of complexation in HA-based nanoparticles in cancer therapy, examining diverse aspects from influential modifiers to emerging trends in cancer diagnostics.

Liver fibrosis is a common pathological stage in the development of several chronic liver diseases, and early intervention can effectively reverse the developing process. Excessive reactive oxygen species (ROS) can promote the activation of hepatic stellate cells (HSCs), but existing treatments have not addressed this problem. In this study, different metal-based mesoporous polydopamine (MPDA) was prepared by the soft template method, and their free radical scavenging abilities, as well as the efficacy and safety of the carriers were investigated, so as to select Cu-coordinated MPDA (CMP) as the optimal nanocarrier.
