Significant research progress has been made in the development of antibody-drug conjugates (ADCs) for the treatment of ad-vanced breast cancer (ABC),ushering new hope for patients with this refractory disease. Through the conjugation of specific antibodies with highly potent cytotoxic drugs,tumor cells can be precisely targeted and killed while minimizing damage to normal tissues. ADCs such as trastuzumab-emtansine (T-DM1) and trastuzumab deruxtecan (T-DXd),have shown excellent efficacy in the treatment of HER2-positive ABC,significantly prolonging patient survival. Furthermore,ADCs targeting triple-negative breast cancer (TNBC),such as sacituzumab govitecan (SG),have also achieved positive results in clinical trials. With the continuous research,development,and optimization of ADCs,as well as the exploration of combination treatment strategies,ADCs are expected to play an increasingly important role in the treatment of ABC in the future. This article provides an overview of the research progress of ADCs in the treatment of ABC,exploring their efficacy and safety. We aim to offer more treatment options and renewed hope for patients with ABC.

" Medical prevention integration" is the practical need of the construction of healthy China and the focus of the construction of medical consortium in the future. Taking the practice of four chronic disease specific medical prevention centers of Wenling County medical consortium as an example, the authors analyzed their practices and experience in coordinating county advantageous resources, establishing organizational structure, and implementing chronic disease specific prevention and control based on informatization. The " medical prevention integration" system constructed by this mode optimized chronic disease service content, improved service capacity and service quality, and achieved in improving satisfaction. This mode could improve the effect and satisfaction of chronic disease management, improve the prevention and treatment efficiency of chronic diseases, and practice the whole cycle health management of chronic diseases.

Objective To investigate the efficacy of lower cervical spine fracture and dislocation treated by Halo-vest reduction combined with anterior decompression and internal fixation.Methods From January 2009 to December 2012,26 cases of lower cervical spine fracture and dislocation underwent Halovest reduction combined with anterior decompression and internal fixation.There were 18 males and 8 females,aged 19-64 years (mean,42.1 years).Injury resulted from traffic crashes in 11 cases,high falls in 9,and hit by heavy objects in 6.Segment of injury was C5/6in 10 cases,C6/7in 9,C3/4in 4,and C4/5in 3.Prior to anterior decompression/internal fixation and fusion,the Halo-vest external fixation was performed.Neurological performance was evaluated after operation.Results All the patients were followed up for 24-36 months (mean,27.4 months).According to the X-ray films and CT scan at the final follow-up,the alignment of the cervical spine was maintained and the implanted bone was completely fused without internal fixation breaking or loosening.Preoperative neurological status according to the Frankel grading was grade A in 6 cases,grade B in 8,grade C in 7,and grade E in 2.After operation,there were 5 cases in grade A,3 in grade B,4 in grade C,5 in grade D,and 9 in grade E.All together,6 cases presented two-grade improvement in neurological status,13 one-grade improvement,and 5 no changes (P ＜ 0.05).Conclusion Halo-vest reduction combined with anterior decompression and internal fixation is safe and effective in treatment of lower cervical spine fracture and dislocation.
