Osteoarthritis is a chronic inflammatory disease characterized by non inflammatory degeneration of articular cartilage and the formation of osteophytes at the edge of the joint, caused by complex causes. Its pathology is complex, and its pathogenesis is not yet clear, ultimately leading to joint stiffness and functional activity disorders. At present, the treatment for osteoarthritis is limited to alleviating symptoms and improving function, with varying degrees of side effects. Ferroptosis is a new type of programmed cell death discovered in recent years, which is related to the pathological and physiological processes of osteoarthritis and plays an important regulatory role in the occurrence and development of osteoarthritis. Its main characteristics include iron metabolism imbalance and accumulation of reactive oxygen species. Therefore, ferroptosis inhibitors targeting ferroptosis have shown great application prospects in the treatment of osteoarthritis. In this review, the author summarizes the relevant mechanisms of ferroptosis in the occurrence and development of osteoarthritis, outlines a large number of specific therapeutic drugs and their corresponding targets, with the aim of delaying and reversing the progression of osteoarthritis by regulating chondrocyte ferroptosis, which has certain clinical guiding significance.

Objective:To analyze current situation of hospice care in Jinshan District of Shanghai and provide recommendations for development of hospice care. Methods:This cross-sectional study included 8 hospice care institutions, their health staff and 316 patients during May-August, 2019. Results were analyzed by quantitative and qualitative methods. Results:There had 80 approved beds in Jinshan District, but only 53 beds were used for 189 inpatients in 2017. Hospice care institutions received financial supports from district government at the construction stage, but relied on their own for daily operation costs. The motivation of health staff to work in hospice care was not strong. Among the hospice care workers, 18% had no certification for hospice care, and only 5% of them had senior professional titles. Continued education for health workers in hospice care was weak and the workers were under heavy stress. Conclusion:The potential needs for hospice care were unmet while hospice care was under-utilization in Jinshan District. The development of hospice care was unbalanced, and the health workers lacked motivation. The resources of hospice care need to be strengthened.
