BACKGROUND:Adipose-derived mesenchymal stem cells have the ability to self-renew and have pluripotent potential under specific conditions in vitro, which have broad application prospects in clinical practice. However, isolation and culture of adipose-derived mesenchymal stem cells stil appear to have many difficulties and shortcomings. OBJECTIVE:To isolate and culture rabbit adipose-derived mesenchymal stem cells in vitro in order to study their morphology, cellsurface markers and biological properties as wel as to investigate the osteogenic and adipogenic potentials of adipose-derived mesenchymal stem cells in vitro. METHODS:Primary adipose-derived mesenchymal stem cells were isolated from the subcutaneous adipose tissue of posterior cervical region from New Zealand white rabbits and digested by 0.1%col agenase I. The cells were passaged and amplified by the trypsin digestion. The passage 4 adipose-derived mesenchymal stem cells were induced to differentiate after exposure to adipogenic or osteogenic medium. The oil red O staining, alkaline phosphatase and alizarin red staining were used to detect the results. The cellviability was detected by the cellcounting kit 8 method to drawn the growth curve. cellsurface markers were examined using flow cytometry. RESULTS AND CONCLUSION:The adipose-derived mesenchymal stem cells isolated from the subcutaneous adipose tissue of rabbits exhibited a fusiform adherent growth in a vortex pattern, and had a strong capability of proliferation that could be passaged stably to the 10th generation. Flow cytometry results showed that the cells highly expressed CD29, CD90, CD44, but lowly expressed CD45 and CD34. After adipogenic induction, the adipose-derived mesenchymal stem cells were positive for oil red O staining;after osteogenic induction, the cells were both positive for alkaline phosphatase and alizarin red staining. These findings suggest that the adipose-derived mesenchymal stem cells were successful y isolated and cultured from the subcutaneous adipose tissue of rabbits, and these cells are pluripotent with the potential to differentiate into adipocytes and osteoblasts, which are expected to be ideal seed cells for bone tissue engineering.

Objectives: This study examined the symptoms and emotions expressed by older adults with cancer and their caregivers in South Korean online cancer communities. It aimed to identify narrative patterns and provide insights to inform personalized care strategies. Methods: We analyzed 6,908 user-generated posts collected from major online cancer communities in South Korea. Keyword frequency analysis, term frequency-inverse document frequency, 2-gram analysis, and latent Dirichlet allocation-based topic modeling were applied to explore language patterns. Sentiment analysis identified 12 emotional categories, and Pearson correlation coefficients were calculated to examine associations between symptoms and emotional expressions. All data were cleaned and standardized prior to analysis. Results: Many users expressed anxiety (20.63%) and depression (19.59%), frequently associated with chemotherapy and sleep disturbances. Among reported symptoms, sleep problems carried the highest negative sentiment (79.81%), underscoring their profound impact on well-being. Topic modeling consistently revealed seven recurring themes, including treatment decision-making, symptom management, and concerns about family, demonstrating the layered and personalized experiences of older cancer patients and their caregivers. Conclusions This study explored treatment-related and symptom-related difficulties faced by older adults with cancer. Many reported significant emotional strain, especially anxiety, depression, and sleep disturbances. These findings highlight the necessity for supportive strategies addressing both psychological and physical aspects of care. Future research could investigate the utility of large language models in analyzing these narratives, provided the data is ethically managed and appropriate for such use.

Arterioureteral fistula is a rare but life-threatening condition. An endovascular treatment approach is commonly used; however, there is a potential risk of infection. We present a case in which a patient presented with abdominal pain and was diagnosed with a ruptured internal iliac artery aneurysm and a subsequent arterioureteral fistula. An aortic stent graft was inserted to treat the arterioureteral fistula, but it subsequently became infected, resulting in the patient's death. This case underscores the importance of early diagnosis and treatment of arterioureteral fistula and the possibility of graft infection.

Sugammadex, the first noncompetitive antagonist developed for the reversal of neuromuscular blockade (NMB), is one of the few drugs that has revolutionized anesthetic practice. However, the use of sugammadex for children between the ages of 2 and 17 years has only recently been approved and is currently not approved for children under the age of 2 years. Although the precision and reliability of reversal of NMB with sugammadex are of great benefit in pediatric anesthesia, several important questions remain regarding its use in our youngest patients. In this brief narrative review, we aim to provide an overview of the key considerations and potential challenges that anesthesiologists often face when using sugammadex in pediatric patients.
