RESUMO
Aim To explore the protective effect of Zishen Huoxue Prescription on OGD/R-induced primary hippocampal neuron damage in rats and the possible mechanism. Methods After the isolated primary hippocampal neurons were identified by immunofluorescence, OGD/R induced neuronal damage, and the changes of autophagic flux at different re-oxygenation time were observed by confocal laser scanning microscopy. After OGD/R-induced primary hippocampal neurons were intervened with serum containing Zishen Huoxue Prescription, cell viability was detected by CCK-8, cell apoptosis was detected by flow cytometry, autophagosomes were detected by transmission electron microscopy, and autophagy-related protein expressions were detected by Western blot. Results 10% Zishen Huoxue Prescription-containing serum could significantly improve cell viability and reduce the proportion of cell apoptosis, increase the number of autophagosomes in neurons, and up-regulate the expression of autophagy-related protein PINK1, Parkin, and pATG16L1. Conclusions Zishen Huoxue Prescription can effectively resist OGD/R-induced apoptosis of primary hippocampal neurons in rats, and its effect may be related to the regulation of PINK1-Parkin pathway to promote mitophagy.
RESUMO
Cast immobilization is a noninvasive and effective option in the treatment of fractures in children. However, its use can be associated with complications, such as pressure sores, skin infections, thermal injuries, and joint stiffness. In clinical practice, retained foreign objects in casts are not uncommon. This study aims to ascertain reasons for foreign objects being retained in casts and their effects on the skin. Eighteen children with retained foreign objects in their casts were identified and interviewed. Patient demographics, type of fracture and cast applied, nature of foreign body, and medical complications caused directly by the foreign object were also recorded for analysis. The foreign objects retained included coins, stationery, toy parts, cutlery, and hygiene items. The most common reason for their retention was to relieve itch, followed by accidental insertion and deliberate play. More than half of the children did not suffer complications, and the rest were all skin complications, with the most severe one being an infected skin ulcer that required oral antibiotics. Although the complications of retained foreign bodies are limited to the skin, they can worsen with delayed treatment. Cast care and itch reduction advice must be clearly communicated to patients and their caregivers. Foreign objects in casts must be emergently removed. Level of Evidence: Level 4 Evidence.
