Hyaluronan (HA) is a non-sulfated glycosaminoglycan that is present in a variety of body tissues and organs. Hyaluronan has a wide range of biological activities that are frequently influenced by molar mass; however, they also depend greatly on the source, purity, and kind of impurities in hyaluronan. High-molar-mass HA has anti-inflammatory, immunosuppressive, and antiangiogenic properties, while low-molar-mass HA has opposite properties. A number of chemical modifications have been performed to enhance the stability of HA and its applications in medical practice. Hyaluronan is widely applied in medicine, such as viscosupplementation, ophthalmology, otolaryngology, wound healing, cosmetics, and drug delivery. In this review, we summarized several medical applications of polymers based on the hyaluronan backbone.

As one of the most commonly used chemotherapeutic agents in clinical practice, cisplatin is unable to selectively accumulate in tumor tissue due to its lack of targeting ability, leading to increased systemic toxicities. Additionally, the effectiveness of monotherapy is greatly limited. Therefore, the development of new cisplatin-based drug delivery systems is essential to improve the effectiveness of tumor treatment.

The glycocalyx and its associated endothelial surface layer which lines all cell membranes and most tissues, dwarfs the phospholipid membrane of cells in extent. Its major components are sulphated polymers like heparan and chondroitin sulphates and hyaluronic acid. These form a fuzzy layer of unknown structure and function.

Objective: To assess the association of serum glycocalyx shedding components (Heparan sulfate, HS; Hyaluronic acid, HA; Syndecan-1, Sdc-1) with outcomes after CA.
Methods: Patients who were comatose for >24 h after CA in the intensive care unit (ICU) of the Affiliated Hospital of Xuzhou Medical University from 9/2021 to 04/2023 were enrolled. Serum samples were collected 24 h after CA to measure the concentrations of glycocalyx shedding components.

In this study, liposomes consisting of soybean phosphatidyl choline (SoyPC) and different molar concentrations (10 mol% and 20 mol%) of dioleoyl trimethylammoniumpropane (DOTAP) were prepared by the thin film hydration method and coated with sodium hyaluronate (NaHA) of different MWs (8-15 kDa, 30-50 kDa and 90-130 kDa) and concentrations (0.01-0.2% w/w) using phosphate buffer (PB) or glycerol phosphate buffer (G-PB) as the hydration medium.

The problem of antibiotic abuse and drug resistance is becoming increasingly serious. In recent years, polydopamine (PDA) nanoparticles have been recognized as a potential antimicrobial material for photothermal therapy (PTT) due to their excellent photothermal conversion efficiency and unique antimicrobial ability. PDA is capable of rapidly converting light energy into heat energy under near-infrared (NIR) light irradiation to kill bacteria efficiently.
