Research progress on ferroptosis mechanism and osteosarcoma LIANG Tao, LIU Zhuochao, ZHANG Weibin Surgical Research and New Technique    2025, 14 (1): 1-8.   DOI: 10.3969/j.issn.2095-378X.2025.01.001 Abstract （385）      PDF（pc） （675KB）（4784）       Knowledge map    Osteosarcoma is the most common primary bone tumor in children and adolescents, with a high degree of malignancy and a poor prognosis. The prevailing treatment paradigm continues to be based on a multimodality therapy of neoadjuvant chemotherapy-surgery-adjuvant chemotherapy, but the survival benefit provided by chemotherapy has remained relatively constant over the past 40 years. Ferroptosis, as a newly discovered form of cell death, has seen rapid research progress over the past decade, and targets for tumor treatment are constantly discovered. Thus, this article commenced with the proposal, developmental nodes, and underlying mechanisms of ferroptosis, then summarized the research results on ferroptosis in osteosarcoma, anticipated its developmental prospects, and highlighted the most urgent things in this field.

Clinical prospects and opportunities for nanotechnology applied to imaging of osteoarthritis LU Rong, CHEN Shuang Surgical Research and New Technique    2022, 11 (1): 1-8.   DOI: 10.3969/j.issn.2095-378X.2022.01.001 Abstract （414）      PDF（pc） （678KB）（2718）       Knowledge map    Osteoarthritis （OA） is the most common bone and joint disease. At present, it is considered no longer just a degenerative disease, but a systemic, metabolic, and inflammatory disease. OA is the main cause of disability of the elderly and one of the sources of social costs. Many new technologies and materials are under preclinical development to address this multifactorial disease. In terms of diagnosis, nano contrast agents for MRI, CT, and PA provide a lot of qualitative and quantitative information about cartilage structure and lesions, which are known biomarkers of OA. The opportunities for the development of nano medicine and the prospects of imaging and diagnosis based on nanotechnology are extremely broad. Reference | Related Articles | Metrics

The preliminary study of apoptosis and calcium metabolism in human colorectal cancer cells HCT 8 treated with Bufalin Surgical Research and New Technique    2016, 5 (4): 225-228.   Abstract （796）      PDF（pc） （2267KB）（2690）       Knowledge map    Objective：To study the influence and mechanism of bufalin on apoptosis and calcium metabolism in human colorectal cancer cell HCT 8. Methods：We used the method of CCK-8 to detect the proliferation of HCT 8 treated with bufalin of different concentrations at 24 hours or the same one at different time. And then , the apoptosis of the cell with different concentrations was detected by Annexin V / PI double staining apoptosis kit. Finally, we investigated the effect of different concentrations of bufalin on intracellular Ca2 + by using Ca2+ fluorescence probe Fluo-3 AM to mark its intracellular Ca2+. Results：The inhibition of human colorectal cancer cell HCT 8 with bufalin showed dose and time dependent manner obviously by the method of CCK-8. The result of apoptosis with flow cytometry illustrated that bufalin can induce apoptosis in the cell HCT 8, and represented a dose-dependent manner. According to the results of the intracellular Ca2+ labeled by calcium fluorescent probe calcium, there was a higher concentration of intracellular calcium when the cell treated at a higher concentration of bufalin. Conclusion：Bufalin can induce apoptosis in the cell of HCT 8, and it may be related to the metabolism of intracellular Ca2+. Reference | Related Articles | Metrics
