Abstract: The differential expression and subcellular localization of single-cell proteins are closely related to the physiological state and pathological mechanisms of the body. The development of single-cell protein in situ imaging methods provides powerful tools for spatial single-cell proteomics research and single-cell protein profiling. This article summarizes the single-cell protein imaging methods developed in recent years, including the circulating immunofluorescence imaging methods based on ordered multi-round antibody incubation, mass spectrometry imaging based on metal element labeled antibodies, fluorescence imaging based on DNA-barcoded antibody, gene encoded fluorescence protein imaging and spectral imaging based on Raman spectroscopy or X-ray spectroscopy, with brief explanation of the imaging principles of these methods. It focuses on the multiple performance, imaging resolution and signal amplification performance of these methods, and analyzes their application characteristics in practical scientific research and clinical work, in the hope of providing some reference for the development of more revolutionary single-cell imaging methods, and promoting the development of biomedical and precision medicine.

Objective:To summarize the main practices and experiences of the Centers for Medicare&Medicaid Services in the US.to pay for artificial intelligence(AI),which can provide references for the formulation of health insurance payment policies in China.Methods:Based on the literature study,it systematically analyzed the payment mechanism and typical cases of AI pay-ment in the US.Results:The US.has established four payment mechanisms for AI used in inpatient,outpatient and physician ser-vices,and set clear criteria for inclusion and payment,which has facilitated the clinical use of AI.Conclusion:It is suggested that China establish the payment mechanism for AI,focus on the clinical benefits of AI,and be alert of the overuse of AI.

Osteoporosis can be induced by various factors including prolonged glucocorticoid usage, diminished estrogen levels, secondary hyperparathyroidism, and alterations in the microenvironment of bone tissue. The bone metabolism imbalance(osteogenic-lipogenic imbalance) plays a crucial role in the development of osteoporosis. This imbalance is primarily driven by an increase in the differentiation of bone marrow mesenchymal stem cells into adipocytes and a decrease in their differentiation into osteoblasts, thus forming the core of the osteogenic-lipogenic imbalance observed in osteoporosis. The bone morphogenesis protein(BMP) plays a crucial role in the regulation of the osteogenic-lipid balance in osteoporosis. This regulatory function is accomplished through both the Smad-dependent and Smad-independent pathways. This review centers on the Smad-dependent and Smad-independent pathways facilitated by BMP, offering a comprehensive overview of the potential mechanisms through which BMP-2, 4, 6, 7, and 9 contribute to the regulation of osteogenesis and lipid metabolism in osteoporosis via these pathways. In order to present novel insights for the identification of efficacious targets for clinical anti-osteoporosis medications.
