Objective: To detect the different proteomic characteristics of microvesicles (MVs) and exosomes (EXOs) released from apheresis platelets during storage, and to explore their role in mediating platelet storage damage lesion (PSL). Methods: Apheresis platelets were collected from the retention bag on the third day of storage. MVs and EXOs were isolated using differential centrifugation. Platelet, MVs and EXOs protein samples were extracted respectively, and the differentially expressed proteins were detected by quantitative proteomics technology. Further, the co-incubation model of MVs, EXOs and fresh platelets was adopted to evaluate the effect of extracellular vesicles on PSL. The aggregation response of platelets to collagen agonizers and the changes in ATP release rate were evaluated by optical turbidimetry. Flow cytometry was used to evaluate the changes of platelet early activation indicators (P-selectin and PAC-1) and mitochondrial membrane potentia. Western blot was used to detect the changes in the expression of key proteins for platelet activation and apoptosis (P-selectin, Integrin β3 and Bcl-xl). Results: Proteomic analysis revealed a significantly separation in protein expression profiles of platelet, MVs and EXOs samples within the latent variable space. Energy metabolization-related proteins such as mitochondrial respiratory chain complex and oxidative phosphorylation were enriched specifically, in MVs while EXOs were enriched with inflammation-related proteins. Co-incubation experiments confirmed that extracellular vesicles could significantly induce platelet responses to agonists (the maximum aggregation rate in the MVs group increased by 187.36%, P<0.001; 71.26%, in the EXOs group P=0.002). The maximum ATP release rate of platelets also increased (275.44% in the MVs group, P<0.001; 70.18% in the EXOs group, P=0.015). The expression of P-selectin increased (119.33% in the MVs group, P<0.001; 25.61% in the EXOs group, P=0.013), as detected by flow cytometry. The binding rate of PAC-1 increased (132.18% in MVs group, P<0.001; 21.41% in EXOs group, P=0.043), and the mitochondrial membrane potential decreased (20.49% in MVs group, P<0.001; 9.73% in EXOs group, P=0.044). In the MVs group, platelet P-selectin and Integrin β3 expression were significantly increased (100.83% and 395.64%, P<0.001), while Bcl-xl expression was lower than that in the control group (83.94%, P<0.001). Compared with the control group, P-selectin and Integrin β3 expression were also increased (27.89% and 181.91%, P=0.007和P=0.002), while Bcl-xl was decreased in the EXOs group (36.52%, P<0.001). Conclusion: MVs and EXOs derived from stored platelets show different proteomic characteristics. Compared with EXOs, MVs exhibits a stronger effect in inducing mitochondrial dysfunction. Mvs also promots PSL responses including platelet activation and apoptosis.

The high-quality development of Traditional Chinese Medicine(TCM)is a significant issue faced by the development of TCM in the new era.Artificial Intelligence(AI),as one of the representatives of new productive forces,is expected to provide strong momentum for the inheritance,innovation,and development of TCM.By focusing on three major directions—intelligent TCM early warning and diagnosis,intelligent TCM treatment and rehabilitation,and intelligent TCM research and teaching—the paper reviews the existing problems and challenges in AI-empowered TCM and proposes solutions.In terms of intelligent TCM early warning and diagno-sis,there are issues with the normalization and standardization of TCM theory itself,insufficient open and high-quality large-scale TCM annotation data resources,and lack of TCM theory and thinking guidance in the design of intelligent methods.In terms of intelli-gent TCM treatment and rehabilitation,there are issues such as the feedback and adjustment mechanism are not yet sound,the depth of multidisciplinary collaborative innovation is insufficient,and technical safety and laws and regulations are not perfect.In terms of intel-ligent TCM research and teaching,there are issues such as insufficient mining and interpretation of TCM implicit knowledge,and insuf-ficient learning and simulation of TCM expert thinking.Based on the above issues,corresponding solutions are proposed to explore ide-as for the research in the interdisciplinary field of"artificial intelligence+TCM"and to provide reference for the high-quality develop-ment of TCM inheritance and innovation.
