Umbilical cord mesenchymal stem cells combined with autologous platelet-rich plasma for lower extremity venous ulcers: A case report and literature review.

Rationale: Nonhealing ulcers are difficult to manage because they deviate from the normal wound healing process. Conventional therapy cannot achieve satisfactory therapeutic effects. To verify the effectiveness of combined treatment with human umbilical cord mesenchymal stem cells (hUMSCs) and platelet-rich plasma (PRP) for nonhealing ulcers, we studied a patient with left lower limb venous ulcer (LEVU) treated with combined injection therapy.

Combined treatment of umbilical cord Wharton's jelly-derived mesenchymal stem cells and platelet-rich plasma for a surgical patient with hospital-acquired pressure ulcer: a case report and literature review.

Hospital-acquired pressure ulcers (HAPUs) are still an important worldwide issue related to the safety and quality of patient care, which are among the top five adverse events reported. Patients who develop HAPUs have longer stays in the hospital than necessary, are at a greater risk of infections, and are more likely to die. Surgical patients are prone to developing PUs because they often remain immobile for extended periods of time, and their surgical procedures may limit the flow of blood oxygen and nutrition and lead to a decrease in muscle tone.

Clinical effect of hydrocolloid dressings in prevention and treatment of infant diaper rash.

The aim of the study was to investigate the application of hydrocolloid dressings in the prevention and treatment of infant diaper rash. A total of 210 infants with diaper rash were included in the study and randomized into 3 groups of 70 infants. Infants in group A received hydrocolloid dressings and individualized nursing; infants in group B received mupirocin plaster and topical application of pearl powder as well as routine nursing; and infants in group C received zinc oxide plaster and routine nursing.

Spectrophotometric studies and applications for the determination of Ni²+ in zinc-nickel alloy electrolyte.

The absorption properties of zinc-nickel alloy electrolyte were studied by visible spectrophotometer. The results show that the relationship between the absorbance of the zinc-nickel alloy electrolyte and Ni(2+) concentration in the electrolyte obeys Beer's law at 660 nm. In addition, other components except Ni(2+) in the zinc-nickel alloy electrolyte such as zinc chloride, ammonium chloride, potassium chloride and boric acid have no obvious effect on the absorbance of zinc-nickel alloy electrolyte.
